MACHINE FOR MAKING BOOK-COVERS.

T0 alt whom it may concern:

Be it known that I, WILLARD P. JACKSON, a citizen of the United States, and a resident of Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented a new and useful Improvement in Machines for Making Book-Covers, of which the following is a specification.

In the art of book making, the covers are generally formed of a flexible material such as leather, leatherette, or paper, which forms the outside cover and is folded over and united with a stiffening of card-board or other suitable material, which forms the inside cover.

My invention relates to machines for performing the operations above indicated and consists of a vertically reciprocating male former, and a female former, provided with horizontally adjustable and vertically movable folding plates; and further of mechanism which operates upon the alternate downward movement of the male former to force the folding plates inward over the female .former, in position to be struck by the male former and to be forced downward into the female former, and of the devices and combi nations of devices hereinafter more specifically set forth and claimed. I

My invention is illustrated by the drawings herewith submitted, in which Figure 1 is a top view of a female former, showing folding plates. Fig. 2 is a front View of a machine embodying my invention. Fig. 3 is a sectional view of a portion of the end of the cross head carrying the male former,.illustrating the arrangement of connected mechanism for adjusting the folding plates. Fig. 4 is a section along X X Fig. 2. Fig. 5 is a partial end view. Fig. 6 is a reverse plan view of folding and guide plates, showing relative position of folding plate adjusted to receive stroke of male former. Fig.

7 is a top view of folding plate and connected guide plate showing connecting mechanism. Fig. 8 is a reverse view of same; Fig. 9, asection on line y y, Fig. 7. I

Similar letters and figures of reference refer to similar parts throughout the several views.

head D, to which vertically reciprocating mo tion may be imparted by several well known devices, which I consider it unnecessary to describe as they form no part of my invention. Immediately beneath the former B, is the female former A, mounted in a suitable table E, and movable along transverse ways on said table, so that it can be drawn out from under the male former, by means of a handle K. I also provide a suitable stop, 26, which stops the female former A immediately under the male former B when pushed back.

I have shown in the drawings a preferred form of folding plates at a a a, (see Figs. 4, 6, 7, 8, and 9,) in each of which an end folding plate is united with a side folding plate forming a singular angular plate a, but this form of folding plate, although "convenient, is not an essential feature of my invention. The folding plates are rendered vertically movable and horizontally adjustable by the following described mechanism to which, however, I do not consider my invention limited.

Each of the folding plates at, a, a, a, is secured to a guide plate 1, substantially as follows: The guide plates 1, 1,1, 1, are provided with flanges 2, 2, 2, 2; through slots cut in saidrflanges extend the uprights 3, 3, 3, and 4,4, 4., 4,21. convenient form and arrangement of which is shown in the drawings, Fig. 1, such arrangementgiving strength to sustain pressure of the .plunger or male former, as hereinafter described, and insuring a parallel vertical motion of the folding plates. To

each of the uprights 3, 3, 3, is secured a spring 5, which is also secured to the guide plate 1. The action of the springs 5, 5, 5, 5, is to keep the folding plates 0., a, a, a,in contact with the bottom of the flanges 2, 2, 2, 2, on the guide plates 1, 1, 1. 1, the folding plates a a, a, a, being pressed downward against the tension of springs 5, 5, 5, 5.

The length of the folding plates at, a, a, a, is

IOO

At the angle in each of the guide-plates, a bolt 6 is secured, forming equal angles with the sides, the bolt 6 is adapted to slide in a grooved plate 7, secured to the former A, the groove therein forming equal angles with the sides thereof. Each of the bolts 6 carries a pin 8, extending through a slot 10 in the plate 7, and a slot 9 in an arm of a shear lever O. to suitable supports on former A, and by the mechanism above described, the opening and closing of said levers adjust the folding plates or, a, a, a, said plates in their inwardoutward motions remaining parallel to the edges of the former A. The springs 11, 11, 11, 11, secured to the blades of the levers 0 act to open the same when closed as hereinafter described.

hen the operation of a machine embodying my invention is described, it will be seen i that it is preferable to operate the shear levers C, C, by alternate downward strokes of the former I find a convenient form of mechanism toaccomplish this result to be to provide each end of the cross-head D with a ratchet 12, mounted on a shaft 13 extending into said cross-head, inside of which substantially as shown in Fig. 3, it is connected with a spring 16,against the tension of which itisdrawn out of-thecross-headD. Gentrallyplaced around theshaft 13, andseoured tothe endof theerosshead D, is a double circular cam 14, the elevationsand depressions in whichare one-hundred and eighty degreesapart. carries a rigid projecting arm 15, provided with an inwardly projecting shoulder which bears against the cam 14, held in contact therewith by theaction of the spring16. -Secured to former A, or to the table E, is atpawl 17, which-engages with the ratchet 12 and at each reciprocation of the former B imparts a quarter turn thereto. turned through ninetytdegreesipassesfrom an elevation to a depression in the cam let or vice-versa and a horizontally reciprocating motion .is thereby imparted to the shaft 13.

The lower part of thecross head D is provided with apertures 20, 20, 20, 20, in which The shear levers O, O are pivoted Theshaft 13 The arm 15 being cover, cut to the proper size, which must be larger than the female former A, is placed upon former A, and the machine set in operation; the male former B falling presses the outside cover to conform to the female former A, thereby creasing and partially turning the fold. When the former B rises,a pasted stiffening, or insidecover, is placed in the outside cover, and the former B-again failing, the ratchet 12 having been given a quarter turn by the pawl 17, the fork 18 strikes the ends of the levers C, G, and closes the-same, thereby closing the folding plates at, a, a, a,which turn in the fold, and the former B, falling on the uprights 3, 3,and 4, t,forces the folding plates a, (t, a, a, downward and presses out the fold which is united to the stiffening by adhesive material placed thereon as hereinbefore described, the plate 1) acting to 'holdthestiffening during theoperation of the folding plates. It will be noted that the plate I) also, by bringing the stiffening to an even surface, prevents the catching .of the folding plates. The machine may be provided with suitable stopping and starting mechanism, and the former Adrawn out by the handleK between the-successive operations of the machine.

Lam aware that lhorizontaliy acting folding plates have been usedonmechanisms for similar purposes, but

I claim as my invention and desire to secure by Letters Patent- 1. In a machine for making book-covers, the combination of a vertically reciprocating male former, a female former, a series of guide plates supported in suitable bearings, a series of folding plates connected to, and horizontally movable with, the 1 guide plates, means for imparting horizontal, parallel motion to the guide and folding plates, and means whereby the folding .plates may be moved vertically 'in relation to the guide plates, all substantially asdescribed.
