BOOK-FOLDING MACHINE.

Z3PECIFICATION forming part of Letters Patent No. 369,599, dated September 6, 1887.

Application filed July 3, 1886. Serial No. 207,114.

(No model.) Patented in England August 20, 1856, No. 10,678.

T0 at whom it may concern:

Be it known that I, EZRA T. HAZELTINE, a citizen of the United States, residing at WVar ren, inthe county of WVarren and State of Pen 11- sylvania, have invented new and useful Improvements in Book-Folding Machines, (for which I have obtained a patent in Great Britain, No. 10,678, dated August 20, 1886,) of which the following is a specification.

This invention relates to improvements in the book-folding machine for which Letters Patent No.- 345,506 were issued to myself and F. A. Weld July 18, 1886.

The object of my invention is to provide novel means for moving the folded book into engagement with the pressurerollers between which the book passes for pressing it along the line of the fold made by the foldingblades.

The invention also has for its object to pro vide novel means for clamping the folded book to move it to the pressure-rollers without undue pressure being applied to the folding- 'blades, so that the knife can rise without liability of lilting the book.

The object of my invention I accomplish in the manner and by the means hereinafter described and claimed, reference being made to the accompanying drawings, in which Figure l is a side elevation of a bookfolding machine embodying my invention; Fig. 2, a top or plan view thereof, broken away at one side on the line so a; of Fig. 1 to show the pressure rollers and the clamping jaws for moving the folded book into engagement therewith; Fig. 3, a vertical sectional view taken on the line 3 g of Fig. 1; Fig. 4, a detail perspective view of one pair of the clampingjaws, showing also a portion of one of the upper book-folding blades; Fig. 5, a detail perspective view of one of the lower blades; Fig. 6, a sectional view of one of the clamp-operating cams, taken on the line 3 3 of Fig. 7; Fig. 7, a side elevation of one of the cams, and Fig. 8 a detail sectional view of one of the clamping-jaws.

In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, referring to the drawings, where- The numeral 1 indicates a supporting framework; 2, the table having at each side a slot,

each of which has at its opposite edges aguideplate, 3.

As in the machine forming the subject-mat ter of the application before referred to, an attendant sits at each side of the table and places one of the flattened-out books, back downward, upon the guide-plate 3 at the time the cross-head 1 is elevated. When the crosshead descends, the vertical blade 5, attached thereto, strikes the book along the folding line and presses it down upon a vertical blade, 6,

which is held in such position that its top edge isjust below the bookback. The lower edge of the upper blade is chanit'ered to corre spond to a groove in the top edge of thelower blade, and the two blades come sufficiently close for the upper blade to press the book at the folding-line into the groove of the lower blade to clamp or pinch the book. The motion of the two blades is thereafter coincident and downward to force the book between the guide-plates 3 sufficiently far to place thefoldline in a horizontal line passing between the pair of pressure rollers 7, after which the blades separate, the upper one ascending, lcaving the book folded between the guideplates. It is now necessary to move the book in a horizontal plane to engage and pass between the pressure-rollers to press the book along the folded line and eject it from the machine into a suitable receptacle. To accomplish this I employ two jaws, 8, preferably of wood and capable of sliding back and forth in a rectilinear path on blocks 9, secured to a cross plate, 10, fastened at its ends to'the frame of the machine. These jaws at one end are curved into projecting points 11, so that such ends may pass between the rollers to or near their peripheral contact. and each jaw is slotted, as at 12, and provided with a metallic wear-plate, 12, Fig. 8, to receive the upper end of a lever, 13. These levers are mounted 011 independent pivot-pins 14, located in a frame, 15, having journals 16, by which it is as in Fig. 4. The lower ends of the levers have attached studs 21, engaging properlyshaped camgrooves 22 in a cam, 23, fixed to a transverseshaft, 24, each of said grooves having within it an elevation, 25, Fig. 6, the construction being such that as the cams are rotated by the shaft 24 the elevations first spread the lower ends of the levers outward to swing them on their pivot-pins 14 to close the jaws 8 against the opposite sides of the folded line of the book, after which the levers are so acted upon by the walls of the camgroovcs as to cause them to swing the swiveled frame 15 in its bearings and advance the clamping-jaws toward the pressing-rollers 7, so that the points 11 deliver the book directly to the peripheral contact-point of the rollers, which grip the book, and'immediately thereupon the jaws are, by the cams, released and restored to their normal position to clamp and advance another book.

In order to prevent the clamping action of thejaws from exerting undue pressure on the upper folding-blade while it is between the folded book, which would interfere with the withdrawal of the blade and be liable to lift the book, I provide the acting face of one of the jaws with a projection, 26, which may consist of a staple driven into the jaws, .if the latter are of wood, which is preferable. This projection is in line, vertically taken, with a notch, 27, in the lower edge of the upper blade, so that the projection presses on the folded book through such notch and to a large extent prevents'the acting faces of the jaws from unduly clamping the book upon the opposite sides of the blade, thereby permitting the latter to rise without disturbing thefolded book.

There are three shafts. 24., 28, and 29, extending across the machine-frame, the shaft 28 having a pulley, 30, for the driving-belt, and also a pinion, 31, engaging a spur-wheel, 32, on the shaft 24, which spur-wheel meshes into a smaller spur-wheel, 33, on the shaft 29, the latter having a bevel-wheel, 34, engaging a bevel-wheel, 35, on the vertical shaft of one of the pressure-rollers, which shaft is geared with the other pressure-roller shaft by gearwheels 36 38, whereby the pressure-rollers are rotated.

The cross-head 4 is secured to a vertical rod, 4, adapted to slide up and down in suitable bearings, and is" operated by a cam, 37, on the shaft 24.. These features, their mode of operation, and the means for operating the lower 1. The combination, with the book-folding blades and the pressure-rollers, of opening and closing and laterally-movable clampingjaws for moving the folded book into engagement with the pressure-rollers, substantially as described.

2. The combination, with the book-folding blades and the pressure-rollers, of jaws moving first towardv each and then together moving laterally for clamping the folded book and delivering it to the pressure-rollers, and means, substantially as described, for so operating the jaws.

3. The combination, with the book-folding blades and the pressure-rollers, of two clamping-jaws, a swiveled frame, two levers pivoted in the swiveled frame, and means, substantially as described, for first operating the levers to clamp thejaws on the folded book, and thence advance the jaws to deliver the book to the pressure-rollers, substantially as described.

4. The combination, with the pressure-rollers for pressinga folded book along its folded line, of opening and closing and laterallymovable jaws for clamping the folded book and delivering it to the pressure rollers, sub stantially as described.

5. The combination, with the foldingblade having a notch, of the opening and closing and laterally-moving jaws, one of which is pro vided with a projection on its acting face arranged in line with the notch in the blade, 9

substantially as and for the purpose described.

6. The combination, with the pressure-rollersfor pressing a folded book, of the sliding jaws, the swiveled frame, thelevers pivoted in the swiveled frame and connected with the jaws, and the cam acting on the lower ends of the levers for moving the jaws to and from each other, and also to and from the pressurerollers, substantially as described.

In testimony whereof IaffiX my signature in presence of two witnesses.
