PAPER-FOLDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 379,698, dated March 20, 1888.

Application filed November 30, 1886. Soria1No.2-20,23B. (No model.)

To aZZ whom it may concern:

Be it known that I, WARREN HILL, of Towanda, in the county of Bradford and State of Pennsylvania, have invented certain new and useful Improvements in Paper-Folding Machines, of which the following is a specification.

The object of my invention is to provide a new and improved machine for folding newspapers ready for wrapping and mailing.

The invention consists in a paperfolding machine constructed with a flier, toothed rollersections for creasing and folding the paper, and a swinging rod also for creasing and fold ing the paper.

The invention also consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of my improved machine for folding newspapers. Fig. 2 is a side View of the same, parts being broken out. Fig. 3 is an enlarged cross-sectional view of the table and Fig. 4 is an enlarged cross-sectional view through the fluted rollers. Fig. 5 is a detail view of the cam. Fig. 6 is a detail view of the cam for operating the paper-holders. Fig. 7 is a cross-sectional view of one of the rollers, showing the contiguration of the end disks. Fig. 8 is an enlarged detached sectional view on the line 3 y, Fig. 1, illustrating merely the mechanism for operating the pins T T. Fig. 9 is a detached view of the fluted rollers, in reduced size, showing their crimping-teeth internieshing and the paper being folded between them.

Similar letters of reference indicate corre sponding parts.

The drivingshaft A is provided with the pulleys A. A flier, B, is hinged at B to the left-hand edge of a platform, 13, at the righthand end of which platform an angle or other bar, B, is fastened edgewise, as shown in Fig. 3. To the under side of the flier B a curved arm, G, is fastened at the hinged end, and to said arma wire, 0, is fastened, which is connected by a spring, 0*, with the opposite part of the frame of the machine. \Vhen the flier is swung off the platform B", its free edge rests upon the frame D, on which a flat bar or plate, D, is mounted to slide diagonally, said plate D having diagonal slots D through which pins D pass into the frame D. The frame D is provided with an edge, D, on which the swinging edge of the flier can rest, and an upwardly-projecting flange, D*. A hook, D projects from the end of the sliding bar or plate D and is adapted to engage with the pin A projecting from the side of one of the pulleys A. An anglebar, a, is fixed on the frame adjacent to and parallel with the inner edge of the flier B, Fig. 1. A spring, E is fastened to the frame of the machine and to a diagonal bar, E, fastened to the sliding bar D and an arm, D, of the same, which arm extends from the bar or plate D entirely across the front of the machine and has its free end rested on the end of the bar B, Fig. 1.

On the shaftAfive cylinder-sections, F, are mounted a short distance from each other, said cylinder-sections each being provided with as many teeth F as there are to be folds in the paper.

Above the shaft A a shaft, H, is journaled in the frame of the machine,on' which as many sections G are mounted, which are shaped like the sections F and have the teeth G, the sections G being shaped in such a manner that the teeth of the same can be passed into the recesses between the teeth or projections of the sections F. The end sections, F and G on the shafts A and H are provided with the teeth entirely around the circumference, as shown in dotted lines in Fig. 7. The teeth F of the section F on the shaft A engage with the teeth of the section G2 on the shaft H, so that said shaft H can be revolved from the shaft A. Through the spaces between the ends of the sections F the curved guidebars I I, Fig. 4, are passed and fixed, between which the papers pass, the rear ends of the guide-bars being connected by the plates J, placed edgewise, between the inner edges of which plates a slot, J, is formed, the curved guide-pieces J forming the sides of the slot, said guide-pieces be'ing fastened to the ends of the bars J.

On the outer surface of that section F next the pulley A, aplate, K, having two teeth, K, is fastened, which can engage with the two teeth K of a collar, K on the shaft L, journaled below the flier at right angles to the shaft A, on the end of which shaft the curved arm L is fastened, which can act on the under side of the flier, as shown in Fig. 3, the plates K and toothed collar being shown in Fig. 5.

A shaft, M, is passed through the several bottom sections, F, and mounted to revol ve on its axis, and is provided with spring-arms M, which can rest upon the sides F of the first teeth of the bottom sections, F, as shown in Fig. 2. An arm, M is fastened to one end of said shaft and can be acted upon by a fixed segmental cam-plate, M, fixed to the frame of the machine, adjacent to the right-hand bottom section, F, as shown in Fig. 1.

A pin, N, projects from the outer surface of the left-hand bottom section, F, and can act on the tooth or projection N of a sliding bar, N, suitably guided on the frame, and having its end connected with the arm 0 of a vertical.

shaft, 0, having the two arms 0 and 0 Fig. 1, at right angles to each other, in which a rod, P, is mounted to turn on its longitudinal axis, said rod being provided at one end with a cranked arm, 0, to which a spring, 0, is fastened, the other end of which is fastened to the arm 0 on the shaft 0. The opposite end of the rod P is provided with a hook, P, and with a lug, P upon which two beveled projections, P and P, on the frame of the machine can act, in the manner that will be set forth hereinafter.

The shaft 0 is also provided with an arm, Q, connected with a sliding rod, Q, suitably guided, and having a projection, Q", on which a pin, Q, or projection on the left hand upper end section, G, can act. A cam-disk, R, is mounted on the shaft A and can act on one end of the lever B, pivoted at B3, and to that end of the lever B opposite the one at the cam R a rod, S, is pivoted, which has the opposite end, S, forked, on which fork a crosspiece, S, is fastened, which slides on the table T at the rear end of the machine, said crosspiece S being guided by a pin, S passing through a longitudinal slot, S in the table T. A- short distance to the right of the cross-piece '8 two pins, T, project up through apertures in the table, said pins being fixed on a crosspiece, U, on the end of a lever, U, pivoted be low the table T and provided at the end opposite the pins T with a weight, U".

To the same end of the lever B to which the rod S is pivoteda rod, W, is pivoted, which is provided at its free end with a wedge shaped piece, W, adjacent to a fixed beveled projection, W, on the upper surface of the table T, said wedge-shaped piece W being slightly to the right of the pivot of the lever U. The table T is provided with a slot, .W, as shown in Fig. 8. A spring, V, is fastened to that end of the lever B to which the rods W and S are pivoted and draws the same in a direction toward the front end of said table T. Asuitable spring, M is provided for bringing the shaft M back into its original position after the arm M on the same has been acted upon by the cam M, as shown in Fig. 4.

The operation is as follows: The sheet of paper is placed upon the platform B and the flier B, as indicated by the heavy dotted line in Fig. 3. against the prong of the hook D and draws the bar or plate D diagonally in the direction of the arrow on. Fig. 1, as said plate is guided by the pins D in the slots D", and thereby the sheet is shifted or moved into the proper position, so that its edges rest upon the tops of the teeth F ofthe sections F, said sections being shown in Fig. 2. The pin A snaps off the hook D and then the plate D is drawn back in the inverse direction of the arrow :10 and into its original position by the spring E. At that moment the teeth K of the plate K on the end bottom section, F, act on the teeth K of the collar K whereby the shaft L is rotated in the direction of the arrow 00*, Fig. 3, and the arm L is swung up and swings the flier B over upon the platform B whereby the sheet is doubledthat .is, folded at its middleand now rests upon the platform B and upon the teeth F. By this time the sections F are in such a position that the arm M passes under the segmental cam-piece M and is swung into the position shown The pin A of the pulley A strikes 7o in dotted lines in Fig. 6, whereby the springarms M are swung down upon the surfaces F of the teeth and hold the sheet on said surfaces. The sections F and G continue to revolve and carry the sheet along with them and crease the same between the teeth F and G of the bottom and top sections, the paper passing between the guides I and I. When the teeth of the sections begin to separate, as shown in Fig. 4, the creased paper rests against the plates J, as shown in Fig. 4, and the sections continue their rotation, and at the proper ti me grasp a fresh doubled sheet from the platform B", and so on. As the sections continue to revolve, the pin N on the lower end section, F, strikes the projection Nfiwhereby the bar N is moved in the direction of the arrow as, Fig. 2, and the shaft-O is turned in the direction of the arrow at, Fig. 1, and thus the hookrod P is swung in the direction of the arrow m, Fig. 1, the hook passing over the top edges of the folded paper 1%, resting against the plates J. The lug 1 strikes the beveled projection P, and thereby the rod is turned ninety degrees and the hook end P is swung down, as shown in dotted lines in Fig. 4, and over the folded paper, the spring 0 preventing the rod P from turning on its axis while it is being swung and before the lug P strikes said projection. By this time the pin Q on the upper end section, G, strikes the projection Q on the rod Q',whereby the shaft 0 is turned in the inverse direction of the arrow x and the hook P drawn through the slot J, and as it is in the position shown in Fig. 4 it pulls the folded paper through with it, whereby the papers are again folded-that is, the folded paper is creased at its middle by being drawn through the slot J. The rod P is swung in the inverse direction of the arrow 00 and when its lug P strikes the bevel pro- IIO jection P, the hook P is swung back into its original position and the paper dropped in the position shown in dotted lines in Fig. 1 and is between the sliding cross-piece S and the pins T. By this time the cam R acts on the rod R and swings the swinging end of the same, connected with the bar S, in the direction of the arrow 51;, Fig. 1, whereby the paper is pressed against the pins T by the cross-piece S. When the bar S is moved a short distance,

the wedge-piece W on the bar \V strikes the bevel V on the top of the table T, whereby the said wedge-shaped piece is forced downward and acts on the lever U and swings the same downward, whereby the pins T are lowered below the surface of the table T, permitting the cross-piece S to press the paper beyond the pins T. The bars Sand \Vare then moved back by the spring V, and the pins T are raised by the weight U on the end of the le ver U, whereby the table is again ready for the next paper. The paper is thus first folded by the flier, so as to have about onehalf of its area. It is then grasped by the spring-fingers M and held on the teeth surfaces F of the bottom sections and creased, the creases made by the sections F and G being at right angles to the crease made by the flier. Then the folded or creased paper is again folded and creased by being drawn through the slot J, the crease formed by being drawn through said slot being at right angles to the creases formed by the sections F and G and parallel with the crease formed by the flier.
