IMPiIiovEMEnITl IN PAPER-PERFORATlNG MACHINES.

Specification formingr part of Letters-Patent No. 189, lill, dated April 3, 1877 application iiled October 6,1876.

To all whom it may concern:

Be it known that I, RosWELI. T. SMITH, of Nashua, in the county of Hillsborough and State of New Hampshire, have invented a new and useful Improvement in Performing-Machines, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure I, Plate l, is a top view of the device. Fig. ll, Plate l, is a vertical view ofthe right side ot' Fig. I. Fig. III of Plate 2 is a vertical view of the left side of Fig. I. Fig. IV is a section ofthe same on line Fig. Vis the sliding platform, which holds the design to be perforated.

Similar letters of reference indicate corre spondin g parts in the several figures.

The object of my invention is to perforate designs in card-board, like the ordinary perforated card-board of the market, while the surface not occupied by the design is not perforated.

The operation of the machine will be hereafter set forth.

The following description of my invention will enable others skilled in the art to under. stand it. v

In the accompanying drawings, A represents the frame which supports the mechanism. rlhis may be of any convenient forni desired, having bearings for the shafts at one end, or at both, as the size and extent ofthe machine may require. B is the shaft through which power and motion is imparted to the machine. C is a shaft supporting and connecting the gear K and ratchet R. D is a platform, with a rack on one end, which engages the gear K, and with parts cut awa-y at its other end,'so as to form a design such as is desired to be cnt in the card-board. F is the punch or punches that perforate the cardboard in connection with the die E. G is an eccentric on shaft B, which, when it revolves, lifts the platform D, and causes the punches that it strikes to rise and perforate the cardboard. H is a cam on the shaft B, which elevates the bar I, and thereby draws back the dog p on the ratchet R. L is a block, which slides on the bar 7c, moving with the platform D, through `its connection with it by the part g. On the block are the forceps h and i, h being a spring, which bears" on the rigidpart t', f

die E is an incline, on which the springQc) is raised, and the forceps are opened for the Ieception of the card-boardl when the platform and block are drawn back. 0n the punch' F is firmly secured the collar b, which prevents the punch from falling below its (the collars) contact with the bracket a', audit also serves as a part on whichl the presser c may act to withdraw the punch from the die and the card-board. c is aspring acting as a presser to withdraw the punch from the die. The pin d projects from c, and its function' is to raise the spring by contact with the rising platform D, thereby taking the pressure of c from the punch F when perfora'ting the card-board. f is a guard, open at top, keeping the platform D in place. lis another guard for the same purpose asf.

. In Fig. III, Plate 2, j is a stop whic'h prevents the bar I from falling lower than is wanted, and bybcing adjustedhgher or lower it regulates, through the ratchet R, gear K, platform D, and block l, the distance the cardboard shall move between the acts of perforation. gis a collar fitting loosely on the shaft C, with oneside projecting as a lever or arm. It supports the dog p, which engages the ratchet It; it also supports the connecting bar o, through which bar the lever qreceives its downwardor backward motion, while its upward or forward motion is given by the spring t.

The dog p is held in connection with the ratchet-by the spring lv'. s-is a wire, secured at one end to an extended part of the dog p, and its' use is to enable'the operator to disconnect the dog and ratchet by pulling the wire, thereby enabling the platform to be drawn back to receive a new card for perforation.` r is a brake, by which friction may be put on the ratchetIt to keep it from moving back with the dog p.

Haviu g described the variousparts of my invention and their functions, I will now proceed to describe its operation. First pull on the wire s until the ratchet It is free from the dog p; then draw the platform back until the spring h strikes the incline on the die E, and is raised by contact with it; then pass the card-board between the die E-and the upper arnN'r FICE.

icm

bracket a until it projects between the parts of the forceps h and I so far as to be firmly held by them when h is removed from the incline n. ,The machine is now in position for work. Revolve the shaft B, and the platform D is raised by the eccentric Gr until the punches that strike the elevated parts of the platform perforate the cardboard. In -doing this the force of the spring c is first relieved from the punches by the part d striking the platform as soon as or before it reaches the punch. The further revolution of the shaft permits the platform D to return to its place, and the punches to be withdrawn from the die and card-board by means of the presser c. At the same time, and by motion of the shaft B, through the action of the cam H and the bar I, 'the dog p is drawn back, and when the bar I is relieved by its progress from connection with the earn H, the ratchet R is, through power received from the spring t, moved forward until the motion of the ratchet is stopped by the bar I striking the stop-bracket y. The gear K and platform D are moved forward by the motion of the ratchet Rthrough its connections with it by means of the shaft C, and the card-board is at the same time drawn between the die and punch the desired distance, the platform and card-board moving simultaneously by the lconnection ofthe slide-block L with the platform through the part g, thus bringing the machine into position for other perforations, when the same motions ofthe machine by repetition will give any desired number of perforations, the extent and positions of which will correspond to the progress of the design on the platform..

Itis obvious that the die-plate E may be extended to any desired length, and the punches multiplied to any desired number, and that if the platform is extended so as to force all the punches into the dies, the surface of the cardboard will be at regular intervals covered with perforations, and also that the platform may be cut away so as tol form ,any design wished for, raised in relief upon the surface of the platform; or the designs may be cut and secured upon the platform, making it a part of the same, and that the punches only which strike the raised design will be forced through the card-board into the die, and where the platform isv cut away the punches are not forced through the cardboard, and it is left plain, thus enabling the operator, by chang- `ing the raised designs on the platform, to

make any wished-for pattern.

I would remark that thegear may be below the platform D, the platform being raised and lowered the same in all its surface; also, that the ratchet may be driven forward instead of drawn back by the action of the cam H .and bar I, the dog being driven back by the spring; also, that the presser c may perform its functions by means of a weight, or by power imparted from the-shaft B by a cam or other device. I would remark that by perforations I d not mean holes broken through card-board,
