s'rIcKING PINS IN PAPER.

Specification of'Letters Patent No. 15,877, dated October 14, 1856.

To all wiz-0m t may concern:

Be it known that I, WALKER B. BAR'rRAM, of lVaterbury, in the county of New Haven and State of Connecticut, have invented a new and Improved Machine for Sticking Pins in Paper; 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, forming part of this specification, in which Figures 1 and 2, are vertical sections at right angles to each other taken'` through the principal parts of the machine. Fig` 3, is a plan of the same. Fig. 4, is a plan of part of the machine indetail. Figs. `5, 6 and tail. p

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

This invention consists in certain new devices and in certain'new arrangements `and combinations of old devices, the whole constituting a machine of novel character for crimping the paper and sticking the pins therein. 1

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

A, is the framing of the machine.

C, is the shaft from which all the working parts of the machine derive their necessary movements. This shaft works in bearings a, a, on the top of and near one end of the framing. i

B, is a roller whichcarries the paper, c, into which, after it has been crimped, the pins are to be stuck, said paper being in a V continuous roll of an indefinite length.

This roller has its journals fitted to bearings Z1, arranged on the-top of the framing at the opposite end to the shaft C.

D, and E, are two rollers hung in bearings in the lower part of the framing, carrying an endless band cl, of india rubber of a width not less `than the width of the paper.

F, is a roller which is arranged in bearings in the lower `part of the framing in such a position that the band (Z eXerts a pressure against a considerable portion of its periphery for the purpose of taking hold of the paper c, to draw it from the roller B, as fast as it is required, the drawing of the paper being effected by an intermittent motion of the roller F, produced by a ratchet wheel G, at'one end of the said roller, which is operated upon at proper intervals by a 7. are side views of some of the cams in de-` dog e, suspended from one end of an elbow lever H, actuated by a simple wiper J, on `the shaft C.

I, 71, see Fig. 1, are the crimpers, of which two pair will `always be used, though I have only shown one pair for the sake of simplifying and preventing obscurity in the drawing. These crimpers are of a well-known character. They are constructed and arranged to advance toward `and recedel from each other by sliding in grooves in a guide piece I', in the lower part of the guide frame K, in which the pin driver L, works, as shown in Fig. 2. The movement of the female crimper I, is produced by its connection with the arm m, of a rock shaft M, arranged below in bearings in the frame A, and the movement of the male crimper c', by its connection with the arm n, of a rock shaft N, arranged relatively to itsubstantially as M is to the female crimper, I. The rockshaft M is furnished with another arm m2, which is operated upon to work the female crimper I, by a cam M', on the shaft C, and the rock shaft N, is furnished with a short arm n2, whichisconnected by a rod n', with a lever N2, which is operated upon to actuate the male crimper z', by a cam N', on the shaft C. `The cams M', N', are simply what are generally known as wipers, as they are required to make the crimpers advance quickly to meet each other and to allow them. to retreat quickly. The retreating movement of the crimpers is effected by springs m3, as, applied to the arms m2, a2, of their respective rockshafts.

O, 0*, are the jaws of a pair of forceps which seize the fold of the crease produced by the crimpers after the latter have retreated, forthe purpose of holding the `said crease closed and in a rigid condition while the pins are inserted through it. The arms j, j, of these forceps work on separate stationary pivots la, c, and are operated upon to close the jaws of the forceps by means of two wipers or cams O', 0", on the shaft C. The forceps are opened again after they have finished their duty, by a spring Z, connecting the two arms j, j, above the pivots 71:, t. i Two pairs of forceps will be required for two pairs of crimpers, viz., one for each pair of crimpers, but both will op erate in substantially the same manner.

` P, P*, are a pair of aws which constitute a holder to hold the pins t, t, upright in readiness for driving through the crease formed in the paper and until after the commencement of the driving operation. These jaws are attached to two levers p, 29,* which work on separate fixed pivots g, g* and are 5 operated upon to close the jaws by cams P, P*, of which separate views are'shown in Figs. 6 and 7. The jaws are liberated at the proper time by the connection of the two levers p, 2),* by `a spring 7, see Fig. 1. The 10 jaw P, contains strips of leather s, s, which project slightly beyond its face so as to constitute the surfaces which hold the pins t, t, against the face of the other jaw, by which means the pins are held with firmness enough to prevent them getting out of a proper position, but are allowed to move longitudinally under the action of the driver I.

Q, is a movable jaw occupying a position below the jaw P, and intended to operate in connection with the upper jaw of the forceps O, 0*, as a second holder of a similar character to P, Pt, the jaw O, of the forceps being furnished with a strip of leather in the face next the jaw Q, like the face of the jaw Pt, of the upper holder. The jaw Q, is slotted for the male crimper z', to pass through it. It is attached to the arm u, of a rock shaft R, which is arranged in bearings between the shafts N, M. This rock shaft is furnished with a shorter arm u, which is connected by a rod u2, with a lever R2, that is operated upon to bring the jaw Q, toward the forceps O, 0"", by a cam R', on the shaft C. The jaw Q, is thrown back again when it is time to release the pin by means of a spring that is applied to the arm u', but not visible in the drawing.

S, is the pin feeder, consisting of a sta- 10 tionary slotted inclined bar in the slot o, of which the pins hang suspended vertically by their heads, which are broader than the slot o. The inclination of the bar terminates at a short distance from its lower extremity where, for a short distance, it gradually assumes a horizontal direction to meet a horizontal slotted plate T, which is fitted to slide in a direction transverse to the movement of the paper, in guides w, fw. The lower extremity of the feeder must not extend laterally beyond the position to be occupied by the last pin of a row. The slot o, which forms a continuation of the slot o, into the plate T, is of a length not less than that of a row of pins. The slot o, receives from the feeder' a suiicient number of pins to form a row and keeps them suspended in vertical positions till the holders take them, after which the plate T, is drawn outward from the machine to make room for the hammer to drive the pins through the holders into the creases of the paper. The sliding motion of the plate back -and forth is produced by the action of a cam T, on a horizontally-moving lever T2, which works at one end of a fixed fulcrum and at the other end takes hold of the plate by a slot and pin connection.

y, y, y2, yg, etc., are a series of angular bars corresponding in number to the nurnber of pins to be inserted in one row, constituting what I call the separator, the duty of which is to take a proper number of pins from the bottom of the feeder, separate them and force them in the slot o', of the plate T, 75 over the holders at the proper distance apart for insertion in the paper. These bars y, y, etc., are fitted to slide side by side transversely of the machine in a guide box, U, which 1s arranged to swing backward so and forward in the machine on a pivot c,

and receives such swinging movement in a forward direction or toward the pins from a short wiper 10, on the shaft C, acting on the upper end of a lever 11, which is connected at its lower end by a rod 12, with a rigid upright 13, attached to the guide box, but receives its backward movement from a spring 23, applied to the upright 13. The forward swinging movement of the box U, takes place at a time when the points of the separating bars y, y, etc., are as close as possible together and all opposite to the same lower part of the feeder. The points of the bars in that condition are at a dis- 95 tance apart corresponding with the diameter of the heads of the pins, and as the bars swing forward with the box, the shanks of the pins being at a short distance apart owing to the greater size of the heads, the said points pass between the pins. The bars y, y', etc., then slide in the box U, one after the other in quick succession, the bar y, which takes the first pin, moving iirst and thus moving the pins away from each other as fast as required according to the spaces required between them on the paper. The sliding movement of the separating bars y, y, etc., in the box U, is produced by a cam V, on the shaft C, acting on a horizontally-moving lever V, one end of which works on the fulcrum pin 14:, and the other connects with a pin 15, on the top of a saddle 16, which slides between the guides of the plate U, and rests within notches 17, 17 in the upper sides of the separating bars. These notches 17 are all of different lengths, that in the bar y, being only just long enough to receive the saddle so that the bar begins to move as soon as the saddle, that in the next bar y, being a little wider, so that the saddle moves a little way before it operates on the bar, that in the bar y2, being wider still and so on to the last bar g5. The separating bars are shown in Fig. 4 close together, as they are before their action, and in Fig. 1 open in the act of separating the pins.

V, is a horizontal lever working on a fulcrum 18, and serving as a stop to prevent 130 the feeder.

the pins issuing from the feeder till the proper time. This lever is operated in such manner by a pin connection at 19, with the lever V, that one end is thrown across the underside of the notch o, of the feeder after the sliding movement of the separating bars in the plate U, and thus stop the pins in This lever is moved out of the way when the pins are to be taken from the feeder by an angle bar if, which stands in advance of and moves along with the first `pointed separating bar y.

The pin driver L which has been before mentioned, for driving the pins into the paper, is attached toa stock K, which slides `in vertical ways in the standard K. Tt has a row of recesses 20, 20, see Fig. 2, counter sunk in its face, corresponding in number with the pins to be inserted, each recess being of proper size and occupying a proper position to receive the head of a pin. These recesses are to hold the upper parts of the pins after the points are entered in the crease of the paper and thus serve to hold the pins upright after the jaws of the holder have opened, which it is desirable they should do as early as possible after having guided the points of the pins to the proper' place in the paper. The pins make their own holes as they enter the paper, no previous punching being required.` The downward movement ofthe driver to drive in the pins is produced by a cam L', one end of which works on a fulcrum 2l, andthe other is attached by a slet and pin connection 22, with the stock K. The driver is raised again by a spring 24, connecting it with the top of the standard K. l

The operation of the machine is as follows: The paper from the roll is conducted over the top of the jaw Pt, of the holder, down below the jaws Pf, P, and between the ends of the forceps O, O, and bar Q, from whence it descends to the roller F, passing between the said roller and the band al. The shaft C, has then a rotary motion imparted to it by any suitable method. The first part of the operation is that of crimping the paper to form the crease or creases to receive a row of pins. The crimpers i, effect `this part of the operation while the holder P, Pf, is open and the paper is free to come from the roll to supply the qnantity taken up in forming the creases. During the operation of the creasers the boX U, receives its movement toward the pins in the lower part of the feeder and its bars y, y after taking a sufiicient number of pins, slide one by one under the plate U, which is at this time close up to the bottom of the feeder and thus place the pins at proper distances apart in the slot 'v, of the said plate. The crimpers now move out of the way and the holder comes into operation and seizes both the pins and the paper alongside of them, about the same time as the forceps come into operation to seize the crease or creases, and then the box U, swings back to carry the separating bars from between the pins, and the plate T, slides outward from the machine to make room for the descent of the driver which comes down and drives the pins through the crease, the holders opening as soon as the heads of the pins have been received within the recesses in the face of the driver and their points entered in the first crease, in order to let the driver pass down between them. The driver after its operation is quickly raised by the spring 24, and the plate T is pushed up again to the feeder, after which the lever H with its dog e, comes into operation on the ratchet Gr, and moves the wheel F, ,which takes away the row of stuck pins and draws from the roll B, a supply of paper sufficient to receive the neXt row, after which the above described operations are repeated with every revolution of the shaft D. The paper having the pins stuck in itis conveyed away between the roller F., and band d, to any suitable receptacle, from which it may be taken and cut into any lengths desired and folded up ready for the market. It should be observed that the separating bars, after having been thrown back from between the pins by the swinging movement of the box U, are caused to slide back,

one at a time, to the position (close together) which they occupied in the first part of the above described operation, to be in readiness to take another supply of pins` from the pin feeder S. When the bars move forward to take the pins, the outermost bar gft, knocks away the stop lever V, from in front of the pins. As the last bar i 5, moves from under the feeder toward the plate T, the pins in the feeder S, are caused to follow it by the action of gravitation on those pins in the inclined part of the feeder. As the bar g5, reaches the point where the first bar g5, and thus prevents the pin moving moved forward, the stop V, is thrown across the slot e between the front pin and the said bar gf, and t-hus prevents the pins moving any farther, and detains the lowest pins in a position ready for the next operation of the spacer and separator.

This machine possesses several advantages over those in common use for a similar purpose, among which may be mentioned, first, owing to the peculiar manner of separating the pins and carrying them toward the de vices by which they are placed in the paper it is almost impossible to leave out a single pin from a row, while in the machines in common use, in which the pins are taken one at a time by the separator, so many pins are missed that much time is lost in supplying their places by hand; second, the work is much more easy and simple for the person in charge of the machine and a much greater amount of Work is performed in a given time; third, the pins are held more firmly in the paper owing to the crease being held closed by forceps during the insertion of the pins through it and afterward slightly opened by the tension produced on the paper in drawing it through the machine, which causes the paper to bite upon the pins; fourth, the sharp front edges of the crease produced by the forceps gives the paper a neater appearance.

l/Vhat claim as my invention and desire to secure by Letters Patent, isf l. The separator and spacer composed of a series of bars g/,y,y2, etc.,having a simultaneous movement at right angles or nearly so to the line of pins in the pin feeder and to the line in which the pins are inserted and a movement one after the other in a direction parallel or nearly so to the said line and operating substantially as and for the purpose herein set forth.

2. The construction of the driver L, with recesses in its face to receive the heads of the pins and act in conjunction with the paper after the points of the pins have penetrated it to serve the purpose of guiding the pins straight and parallel through the paper, thus enabling the holder to be opened to make room for the driver, substantially as herein described.

3. The stop V, acting in combination with the separator and spacer, substantially as described, to retain the pins behind the separator and spacer after a number suficient for one row has been taken from the feeder by the separator and spacer, but to be moved away by the separator and spacer.

et. The bar Q, operating in combination with the forceps O, O, substantially as de-` scribed to form a second holder below the principal holder P, Pf, and more perfectly secure the upright and parallel positions of the pins during the commencement of the driving operation.
