SIDNEY KELSEY, OF ERIE, PENNSYLVANIA.

-llvlPRovEn PRINTING-PRESS.

Specification forming part of Letters Patent No. 12183, dated January 2, 1855.

To all wtom/ 1115 may concern:

Beit known that I, SIDNEY KELSEY, of Erie, in the .county of Erie and State of Pennsylvania, have invented a new and Improved Printing-Press; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, ia Which- Figure l is aside elevation of my improved press. Fig. 2 is a longitudinal vertical sec- A tion of the same, taken at the linex, Fig. 3.

Fig. 3 is a plan or top view of the same.

Similar letters of reference indicate corresponding parts in the several figures.

The nature of my invention consists, first, in the peculiar' means employed for feeding the sheets of paper to the form, and, second, in the peculiar mode of operating the H y. j

To enable others skilled inthe art to make and use my invention, I will proceed to describe its construction and operation.

A represents the frame of the press, constructed in any suitable manner, and Bis the platen, the ends of which work up and down in guides a in the sides of the frame. (See Figs. 1 and 2.) I

Underneath the guides a are spiral springs h, which give the upward motion to the platen. The downward motion is given the platen by a lever C, which is attached to one end of a shaft o, which extends the Width of the frame. The outer end of this leveris connected byan armD to one of the guides ct. The inner end of the lever C is operated at the proper time by a pin d on a toothed wheel D at one side of the frame A, said toothed wheel being hung upon a shaft E, as shown in Fig. 3. The opposite end of the shaft c has a small lever e attached to it, the outer end of which isalso connected by an arm F to the guide at the opposite side of the frame. (See Fig. 3 and dotted lines, Fig. 2.)

G, Figs. l and 2, is the bed on which the form to be printed from is placed. The bed is permanently secured on the upper part of the frame A, near its back end and underneath the platen B.

II is a carriage which runs in grooves f f on the upper part of the frame A. (See Fig.

3.) .This carriage is formed of two parts g h. The inner end of the partg has an upright projection t', (see Figs. l and'2,) having springs jj upon it, and at the outer side of the proi spring o', and a pulley b' jection an ink-roller k is placed, the axis of the roller running in bearings at the ends of the projection. The outer end of the part g, of the carriage has a bandi attached to it, said band being also connected to the periphery of a pulley I, which is hung upon a shaft J, having a spiral spring m around it. (See Fig. 3.) The part h of the carriage is fitted upon the part g, thin plates n being placed between the two parts, with small spiral springs o underneath them. (See Fig. 2.) The part h is kept properly adjusted upon the part g by means of nuts p, which are fitted upon pins'q, secured in the lower part g of the carriage, said pins fitting in ,recesses r in the outer edges of the sides of the part h. (See Figs. l, 2, and 3.) The outer .end of the part 7L has a series of notches s cut in it, as clearly shown in Fig. 3. rlhe use of these will be shown hereinafter.

K is a projection secured to the outer end of the part 7L and having one end of a bandt attached to it, the opposite end of the band being secured to the periphery of a pulley L, as shown in Fig. 2. rlhe axis of the pulley L is secured in the outer end of a lever M, having its fulcrum at u. One side of the pulley I. has a toothed wheel N attached to it, as shown in Figs. l, 2, and 3 On the inner end of the shaft E, on which the toothed wheel D is hung, there isa cam O, which, as it rotates, acts upon the inner end of the lever M, as will be shown hereinafter.

Directly underneath the pulley L there is a shaft P, having a toothed wheel Q upon it, which at certain times gears into the toothed wheel N, as will be hereinafter explained.

On the outer end of the shaft P there is a band-wheel R, having a band o around it, said band also passing around a pulley S at one end of a driving-shaft T. The opposite end of the driving-shaft is provided With a iiywheel U and a pinion V, which geagsxinto the toothed wheel D. (See Figs. l and 3.)

At the back end of the f/raine A there r' are four ink-rollers w, placed underneath and at the side of an ink reservoir or fountain y. (See Figs. l, 2, and 3.)

IV is a ily which is formed of a series of rods e', attached to a shaft X, which has its bearings inf/the top part of the frame A. Around the shaft X at one end there is a is also attached to 011e end of the shaft, said pulley' having a cord c attached to its periphery, the cord being also secured to the part g ot' the carriage H. (See Figs. 2 and Y is a pawl attached to the end of the frame A. This pawl acts or catches against a notch d (See Fig. 2) on the pulley b at a certain time, as will be presently shown.

The sheets of paper to be printed are placed upon a feed-board Ar, the innerend of which is curved upward, as shown clearly in Figs. l and 2, and is provided with a slot d in the angle of the curve. The sheets are passed through this slot d', and their edges pass between the projection t' on the part g ot' the carriage and the edge of the part h, as shown in Fig. 2, a space being between thelipt' andthe part h in consequence of the springs j. The sheet of paperis indicated by e and shown in red, Fig. 2. Motion being given the drivingshaft T, the cam O rotates in the direction indicated by the arrow,Fig. 2, and is free from the lever M, the outer end of which is depressed by a spring B at its inner end, and the two toothed wheels N Q gear into each other, and motion is given them, as also the pulley L, by means of the band fu, which passes around the pulleys R S. As the pulley L rotates, it winds the band t around it, and the carriage H is drawn underneath the platen B and over the forni on the bed G, and as the bandt is attached to the projection K on the part h the edge of said part h adjoining the projection 'L' will overcome the power of the springs j j and bear against the projection fi, the edge of the sheet e being grasped between them. The sheet is thus carried with the carriage H between the platen and bed. Just before the carriage gets underneath the platen B the cord c acts upon the pulley and turns the shaft X, the rods z being turned over in a horizontal position and occupying the place the carriage left, the pulley being retained in proper position by the pawl Y, which catches against the notch d. When the carriage is between the platen and bed, it is retained at that point by a spring-catch f. (See dotted lines, Fig. 3.) The platen B now descends upon the sheet and presses it against the forni on the bed in consequence of the pin (Z on the toothed wheel...l) acting against the end of the lever C. )Vlien the platen returns to its original position, the cam O de-y presses the inner end of the lever M, and the toothed wheels N Q are thrown out of gear and the spring-catch f depressed by an arm g on the shaft E.. (See Fig. 3.) The pulley I now rotates in consequence of the spring m on the shaft J and the carriage is drawn back to its original position, the rods a of the ly W fitting in the notches s in the outer end of the parth of the carriage, the sheet of paper passing over the rods z or on their upper surfaces. Just as the carriage reaches its original position a small rod at the outer end of the carriage throws up the pawl Y, and the spring a on the shaft X throws the shaft around, and also the rods z, to their original position, the sheet being deposited thereby upon a proper fiy-board. The form is inked by the roller k on the carriage as said carriage passes between the bed and platen. The roller 7o receives its supply of ink from the rollers w, with which it comes in contact when the carriage is between the bed and platen. Motion may be given the rollers w in any proper manner.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Feeding or conveying the sheets to the form by having the carriage H formed of two parts g 7L and arranged substantially as herein shown, so that the edge of the sheet may be grasped between the two parts of the carriage as it is moved between the platen and bed.

2. The fly YV, operated as herein shownviz., by means of the pulley b,attached to the ca`rriage H by a cord c', said pulley bein g hung on the shaft X, which is provided with a spring a', as set forth.
