' PERFORATING-MACHINE.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, THOMAS A.- MCCALL, a cltizen of the United States, residing at Cincinnati, in the county of Hamilton and I the like.

The invention consists in the construction and combinations of parts hereinafter de scribed, and pointed out definitely in the claims. 1

In the drawings, Figure 1 is a side elevation of a machine embodying the invention. Fig. 2 is a plan view thereof. Fig. 3 is a transverse sectional view in'thc plane indicated by line 33 on Fig. 2; and Fig.

4: is a sectional View of one of the punches and the parts associated therewith.

A represents a roll on which is wound the paper strip ,to be perforated, which roll is hung loosely in bracket arms 7) fixed to the frame members B of the machine.

C represents a roll on which the perforated paper strip S is finally wound. which roll is hung in other fixed brackets Z). The spindle c of this latter. roll has a pulley a, over which the belt F runs. This belt runs also over a pulley d fixed to a driving shaft D, which extends transversely and is meant ed in bearings in the two side members of the frame. The belt is suiliciently loose to enable it to slip, if necessary, but sutliciently tight to enable it to turn the receiving roll (3 as much as is necessary to take up the slack of the paper.

A horizontal cross bar 1*] extends between and is fixed to the side frame members. Near its ends, hardened die plates G are 1Tlset into, its upper surface, which die plates have holes 9 registering with holes 0 below them in the bar E. Punch guide blocks H- are fixed to the side frame members, and each of these has two vertical guide holes in which the reciprocating punch bars K, K

and K, K are guided for vertical movement. The punches L- on the lower ends of vertically movable horizontal bar J which extends transversely across the machine, its ends being connected with the upper ends of the two slides M, M, which are mounted for vertical endwise movement. in guidcways fixed to the side frame members. 011 the shaft D and at opposite ends thereof are the two eccentrics N; N, whose eccentric straps 71,02, are pivotally connected with the lower ends of the bars M. \Vhen the shaft D is rotated, the four punches will, through the described mechanism, be moved up and down, said punches 7.: descending far enough to punch holes in the paper strip'which runs across the bar E. Below the holes e,'e, chutes 1 ,are fixed to receive the paper disks punched from the paper, and to carry them to a scrap receiver.

The paper strip S passes over the bar E, as stated, and its edges pass likewise beneath the lower ends of the punch guides H, which lower ends are placed pretty close to the bar 1'), so that the paper is prevented -from buckling or crinkling at the points where the perforations are tobc made. To keep the paper straight, however, entirely across the bar while the perforations are being made. four resilient pressure bars R, R, R, .R are employed, the two pressure bars R, R, at the left side being curved to the left, and the two pressure bars R, R, near the left side being curved to the left. These four bars are fixed to the reciprocating bar J. Each of these pressure bars consists t'reierahly off a flat spring 7 over which a rubber sheath .r is drawn. \Vhen the bar J descends, these spring pressure bars will strike the paper at the merest instant before the punches strike it, and will press it down Patented Dec. 31, 1911.2, Application filed March 8, 1912.

Two .levers T are'pivot'ed to the side of the frame, and a roller 25 is mounted in their outer ends, which roller rests on top of .the

This roller has also. two collars t t, which,

by engaging the edges ofthe paper, help to guide it, and to .keep therollofpaper in the proper position. I

' Two' levers U are respectively pivoted to the frame which is composed of the two levers T, and.roller t, and hang at an angle downwardly therefrom, and a roller u" is mounted their ends.

The ratchet g is fixed to one endfof. this feed roll spindlew A bell crank lever is pivoted to one of the side frame members, and it carries apawl 'v for engagement with this ratchet,--a spring '0 acting to preserve this engagement. In the horizontal arm of this bell crank lever is a slot which embraces a pin m fixed to one of-the vertical movable bars M. 'Every time this bar moves up, it rocks this bell crank lever, and this lever, through pawl '21, acting on ratchetg, turns the feed roll through a definite arc. A spring yengaging with this ratchet acts as a brake to prevent the feed roll from turning too far, and also acts asa dog to prevent it from turning backward while .thepawl'is moving backward.-

A curved plate Z is fixed to the side frame members adjacent'to the feed roll and pre- -vents thev paperstrip from becoming disengaged from the-saidfeed roll.

The drawing shows by dotted lines in Fig;

1 an electric motor, and in Fig.2, together with the dotted lines in Fig. .1, is shown a train of mechanism for transmitting motion from this motor to the driving shaft.
