Application August 30, 1956, Serial No. 607,074 7 Claims. (Cl. 101-269) This invention relates broadly to the art of printing and, more particularly, to means used in printing for making a proof copy of set type. While the invention is useful in all printing operations it has a particular field of usefulness in the printing of newspapers and, without in any way limiting the invention or the claims which define it, the invention will be described in this application in connection with the printing of a page, or part of a page, of a newspaper.

In the usual and conventional printing of a newspaper each page, or any part of a page, is made up by assembling slugs of type in a chase on a table or bench known as the make-up bank. After this is done and the type is locked in the chase, the form, as it is known, is moved, usually on a wheeled carriage, to a stationary proof press where it is moved from the carriage to the press. After a proof sheet is made the form is moved from the press onto the carriage and taken back to the makeup bank. The sole purpose of this laborious and timeconsuming operation is to make a proof sheet from which it may be determined whether changes must be made in the type which is locked in the form. My invention has the same purpose, which is the making of a proof sheet, and its principal object has been to provide a means of making a proof sheet which will require a minimum time, which will eliminate the necessity of moving the madeup forms, and which may be carried out at the make-up bank. Another principal object of the invention has been to provide a device which may be applied directly to a made-up form at the make-up bank or elsewhere in order to take a proof of the set type without moving the form itself and which is light in weight and easily portable, whereby it may be moved from form to form to take proofs, thereby eliminating any necessity of moving the forms to the proof press and, further, eliminating any need for the usual stationary proof press.

An embodiment of my invention is illustrated in the accompanying drawings, in which:

Fig. l is a front elevational view of a portable proof press according to the invention in operative position on the chase of a made-up form, showing the inking roller below the pressure roller;

Fig. 2 is a view which is similar to Fig. 1 except that the positions of the two rollers are reversed;

Fig. 3 is a sectional view taken on line 33 of Fig. 1;

Fig. 4 is a sectional view taken on line 44 of Fig. 2;

Fig. 5 is an enlarged sectional view taken on line 5-5 of Fig. 1;

Fig. 6 is a front elevational view of a modified form of my invention, and

Fig. 7 is a sectional view taken on line 7-7 of Fig. 6.

The portable proof press provided by my invention and illustrated in the drawings comprises a rigid frame having spaced, parallel, vertical side plates 2 connected at their upper parts by a rod 4 and at their central parts by a shaft 6. Adjacent the lower edge of the inner face of each side plate there are provided three rollers 8, 10, 12 which extend in a row parallel to the horizontal lower 2,901,971 Fatented Sept. 1, 1959 ice edge of the plate and are spaced apart in such a way that roller 8, which is adjacent to one side edge of the plate, is spaced from the nearest roller 10 by a distance greater than the spacing between rollers 10 and 12. An elongated metal member 14 is attached to the inner face of each side plate 2 above the rollers 8, 10, 1.2 and has a horizontal lower edge spaced above the rollers. This rigid frame, with the parts which are to be described hereinafter, is adapted and intended to the mounted on a chase 20 for the purpose of taking a proof of the type within the chase. As is well known to the art, a chase consists of a rectangular metal form having side members 22 and end members 24 defining a central opening somewhat larger than the printed area of a newspaper page and within which slugs of type are assembled and locked. In accordance with the invention the two parallel side members of such a chase are undercut, as shown at 26, to form parallel passages which receive the rollers 8, 10, 12. Instead of being undercut the side members of the chase may have longitudinally-extending metal strips attached to their outer side surfaces, which are of less vertical height than the side members and thus provide passages beneath these strips in which the rollers are received. In either case the passages are of proper size to receive the rollers 8, 10, 12 and the parallel members 14 on the side plates 2 are spaced from the rollers a sufficient distance to permit the horizontal lower surfaces of these members to loosely engage the upper surfaces of the side members 22 of the chase when the portable proof press is put onto the chase. It will thus be seen that the frame which has been described may be picked up, put onto a set-up form with the rollers 8, 10, 12.0f the two side plates in the passages 26 in the side members of the chase and the horizontal, lower surfaces of the members 14 in loose engagement with the upper surfaces of the side members 22 of the chase and, with the parts in these positions, the frame and its associated parts may be moved back and forth from end to end along the chase by pushing and pulling on the rod 4.

Means are provided by the invention for alternately inking the set up type 27 within the form and applying pressure to the type through the intermediary of a sheet of paper placed on the type. Such means comprise a carriage 28 which is mounted on the shaft 6 and which has spaced end members 30, an inking roller 32 and a pressure roller 34. The end members 30 are preferably identical in construction and each comprises an elongated metallic member which is journaled adjacent its center on the shaft 6 so that it may be rotated about and with respect to the shaft. Adjacent each of its ends the shaft 6 is provided in its outer surface with three elongated slots 34, 36, 38 which extend lengthwise of the shaft and the longitudinal center-lines of which are spaced at intervals about the shaft, the middle slot 36 opening vertically upwardly and the two other slots 34, 3% being at opposite sides of the shaft when the carriage 28 is in its normal or inoperative position as shown in Fig. 5. Each end member 30 has a bearing block 40 surrounding the shaft 6 and a radial opening 42 is provided in each of these bearings through which a headed locking pin 44 extends. A spring 46 surrounds each pin 44 and constantly urges the pin toward shaft 6 to a position in which the end of the pin extends into one of the slots 34, 36, 38 to thereby lock the carriage 28 to the shaft.

As described above, each end member extends radially outwardly in opposite directions from the shaft 6, thus providing aligned members at the opposite ends of the shaft 6 which provide means for supporting the opposite ends of the inking and pressure rollers. Thus, the parts 50, 52 of the two end members are aligned with each other and rotatably support the opposite ends of a shaft 54 which is covered with suitable material to form an inking roller. Each of the parts 50, 52 of the two end members is hollow and has within it a block 56 having an opening within which an-endofshaft 54 is journaled. A compression spring 58 is disposed between each block 56 and the central block 40 of theend member and constantly urges the block 56'and shaft 54 outwardly. At the other side of shaft-6-the parts 70, 72 of the two end members extend radially outwardly from shaft 6 and have substantially the same construction as the parts 50, 52 of the end members, thereby providing a resilient support for the pressure roller. Thus, the parts 70, 72 are aligned with eachother and rotatably support the opposite ends-of a shaft 74 which is covered with suitable material to form -a pressure roller. Each of the parts =70, 72 is hollow and has within it a block 76 having an opening within which an end of shaft 74 is journaled. A'compression spring 78 is disposed between eachblock 76 and the central block 40 of the end member and constantly urges the block 76 and shaft 74 outwardly. Anadjusting screw 80 is tapped into the end wall of each of the'parts 50, 52, 70, 72 of the endmembers'and may be selectively 'turned to adjust the tension of the springs '58, 78.

The pressure roller 34 is preferably slightly larger in diameter than the-inking roller 32 and if this is the case theparts 50, 52 which support the inking roller must be madelonger than :the parts 70, "72 which support the pressure roller in order that the distances between the axis of shaft 6 and the outermost points of the periph- -eries ofthe-inking and pressure rollers will be equal.

- the :passages.

The distance between the axis of shaft'6 and the outer surface of the pressure roller at the point whereit :engages the typeisslig'htly greater than the distance between the axis of shaft 6 and the 'upper surface of the type in themade-up form and when thepressure roller is moved in the described manner in engagement with the type it inking roller 'ismoved in the described fmanner-into engagement with the type the springs 58' which urge the The entire proof press is now moved back and forth along the entire length of the made-up form causing the inking roller to pass over and engage and ink all of the type within the form.

After the inking of the type is completed the portable proof press is moved to the end of the form, but not moved off of the form, and a sheet of newsprint is placed over the type. The pins '44 are pulled out of the slots 34 and the carriage is rotated about shaft 6 until the pressure roller is vertically .below the inking roller, as shown in Figs. 2 and 4, in which position the pins 44 may be released to permit the springs 46 to force them into slots 38, thus locking the carriage from rotation with respect to shaft "6. The entire portable proof press is now moved along the entire length of the made up form, causing the pressure roller to press the newsprint into engagement with the type after which the portable zproof press may be removed from the form or "it"rnaybe moved to one -end of the form and a second ipro'of'taken by removing the :printed sheet of newsprint, placing a fresh sheet .on the type in the form and repeat- .ingtthe described operation.

The spacing'z-of theirollers 8, .710, 12 which is described -above permits Jthe portable rproo'f ."press to be .partly moved beyond thec'end 'offa chase, by allowing the rollers 8 to pass out of the ..ends*of:the passages 26 while tpreventingithe other rollers :10, 712 :from coming out of This permits the portable proof press to ibe rnovedto atposition where ittis not-above the type-in theform, thus :perrnitting theprinted sheet of newsprint to be :replaced bya new sheet.

Any suitable means may bezprovided within the scope of the invention for supplying ink to the inking roller, sand in *Figs. 6 and 7 of thefdrawings I have illustrated an Fembodiment of f the invention in which such a 1 means is incorporated in'ithe portable proof :press. This means r'comprisesxa tubular ink reservoir 90 which is supported on'i-the outeriends'of1pivoted #arms 92, :the inner ends of which are supported *on or adjacent the central parts 1 of the 'two:'end members 30. The outer surface of the reservoir is :in engagement with the outer surface of the inking roller 32 and is constantly urged into such contact by springs 94 which extend between the arms inking roller outwardly will be compressed, thusforcin'gthe surface ofthe inking roller into tight engagement with the type.

It will be seen 'that the carriage which includes the two end members and the inking andpressure rollers is a unitary'structurernounted-on shaft'6 and capable'of being moved-about and with respect-to the shaft'to three positions-in which itrnay be locked. Thus, if it is desired to take aiproof .oftype in a made up formthe portable proofpress provided'by-the invention is first 92 and the end members 30. The reservoir'90 cornprise's r two tubes :96, 98 which fitone within the other and have closed ends and are :rotatable with respect to each other bykknurled knobs 100 on i their ends to bring apertures in the tubes into register, thus permitting ink to @fiow from :the reservoir to the inking roller, after which the two tubes may be rota-ted relatively' to each "other-to s'top the how of ink. A crank 102 is journaled in oneofthe'side plates 2 andhas a fitting-104 on its inner end which may be engaged with a fitting 106 on adjusted so that the carriage- 28 is-in its middle position, a

as shown'in Fig. 3, with the end members horizontal and the inking and pressure rollers-in side by side-relation. The press is now placed'onthe m'ade'up form atthe make-up 'bank orelsewhere, with therollers 8, 10, 12

positioned within=the passages '26 'in'the side members I 22 of th'e'chase and-the horizontal lower surfaces of the members 14 loosely engaging-the upper surfaces ofthe sidernemb'ers of the chase. The portable pressis'now in position'to be operatedand the'nextstep'in its operation is'to ink the type in the-form. In order to do this the pins 44 are pulled outwardly against theforce of springs 46 untiltheir ends come out 'of the middleslots '36. The carriagemay 'nowbe rotated about shaft 6 through an angle of 90 until theinking roller is-ve'r'tically below the'pre'ssureroller, 'as shown in Figs. '1 and '3 and in which position the pins 44 may be released to cause'the springs 46 to fo'r'ce them into the slots 34.

the end of'the shaft 54:which supports the inking roller. In order to replenish the supply of ink on the inking 'roller thecarriage 28 is'turned to the position in which the inking roller isabovethepressure-roller, as shown 'in FigsJ-2 'and 4,.and-tubes96, 98 are turned relatively to each other to permit ink to flow from the ink reservoir to the surface of the hiking roller, the crank 102 is pushed I inwardly in-order 'toengage the fittings104, 106 with each other-andthe crank is-then turned, causingfihednkingrol-ler 32-to be rotated. Ink will flow fromthe reservoir '90-to'thesur'face of the inking roller and when the entire surface has been covered the crank may be-wi'thdrawn and'the knobs on the reservoir tubes turned in order to close the apertures in the reser- 'VOlI'.

WhileThave described my invention in this application'appliedto themaking of a-jproofcopy from type 'it 'will'be apparent th-at it-is equally applicable to the making of a proof copy from photo setplates, photoengraved-plates, stereotype or any othenplates or other devices .-used the .printing art to transfer words, H pictures or any other intelligence to paper or other material. It is therefore to be understood that the word type as used in this specification and in the "appended claims means, generically, type, plates and all other devices for performing the above-described function. Further, while I have referred in this application to type locked in a chase, it will be understood that the invention may be used to make a proof copy regardless of how or whether the type is held in the chase.

While I have described and illustrated one embodiment of my invention, it will be apparent to those skilled in the art to which the invention relates that other embodiments, as well as modifications of that disclosed, may be made and practised without departing from the spirit or scope of the invention, for the limits of which reference must be made to the appended claims.
