Specification forming-part of Letters Patent No. 48,479, dated June 27, 1865.

To all whom it may concern:

Be it known that .I, LEVERETT BRADLEY, of Jersey City, in the county of Hudson and State ofNew Jersey, have invented, made, and applied to use a certain Improvement in Means Qfor Perforating Paper for Telegraphic Purposes; and I do hereby declare the following to be a full, clear, and exact description of the ,1; said invention, reference being'had to-the annexed drawings, making part of this specification,whereinc Figure l is a plan of my apparatus. Fig. 2 is a side elevation, a portion of the frame beof the punchingdevice.

j i Similar marks of reference denote the same parts. a

The nature of my said invention consists in a punch of a peculiar characterfitted to perforate a strip of paper, and in combination therewith I employ a pair of rollers actuated paper along a given distance each perforation. I also employ levers .to actnpon the said pair l of rollers to cause the strip of paper to be :drawn along sufliiciently to form spaces between the'perforations for representing letters or for making the sp'acesbetween the respective letters or the words. In the drawings, ct represents a table or bed carrying the partsof the apparatus.

b is a triangular frame, in which the punch c is fitted to slide. This punch is kept up by the spring at when ina normal position, and 3 when depressed so that the end passes into 1 and punch, as seen by the red line, is perfof i rated. I prefer that the punch have a square end, so thata series of holes cutting into each other will form an elongated opening in the paper. The punch is actuatedvby the lever f on the fulcrum 1, from which leveris a link, 9, to an arm, h, from the rock-shaft '5, that is actuated by the lever 70. l is aspring to raise the lever k, and m is a stop regulatingthe amount of motion that can be given to the moving end of the lever is. By means of the nuts 2 2 on the leverf and the shackle 3 in the link 9 the movement communicated from the lever-k to the punch 0 can be regulated so that the perforation ofthe ing removed; and Fig. 3 is .a vertical section by themovement of the punch 'for'drawing the l the dies the paper passing between .the die "paper will be smooth and cleanly out, but no unnecessary motion be given to the punch c.

n is a roller on the shaft 0 in the frame ,1), and q is a second roller pressed toward a by springs, (see dotted lines in Fig. 2;) and 4 4 are screws acting on the springs to regulate the power with Which'the rollers are pressed together. The strip of paper passes through between these rollers and is drawn along by them as the punching progresses. An arm, 1', from the rock-shaft'i is provided with a sliding pawl, .9, taking a wheel, t, or. the shaft of the roller n, which wheel is pro", vided with ratchet-teeth. zis a guide-stud for the pawl s. The size of these ratchet-teeth is such that at every stroke of the punch the slidin g pawl s will cause the rollers to draw the paper along a little less than the width of the perforating-punch. Thus the working of the lever it alone would form an elongated perforation iu the strip, of paper. This is necessary for the production of the dashes employed in of perforations representing a letter I employ the lever 22, with an arm, 00, and pawl 00, that takes the teeth of the ratchet-wheel t aud in consequence of the amount of movement given tosuch pawl 00 it will take two teeth each reciprocation, and thus move the paper suflicientlyto leave the space for separating groups of perforations representing letters.

; 1t willbe apparent that theoperator, by working the lever kwith one hand and the levers t and o with the other, can produce single per forations, spaces, or elongated perforations in the strip of paper or other material, so that the same can be used in the usual or an y known manner of transmitting electrical pulsations in telegraphing.

The strip of paper may be led beneath a spring, w, and between guides at 7 7, thence beneath the punch and through between the rollers and n, and pass away when perforated to any suitable receptacle, and then afterward ters Patent, is-

- 1 The punch 0, actuated by the lever h, and regulated in its moyements by the adjustment of the nuts 2 2 and shackle, substantially as specified.

2.' A reciprocating punch, in combination with a pair of rollers for drawing the paper along, and with a ratchet-movement actuated by thereciprocation of the punch, substantially as specified.

- 3. .A spacing lever or levers, coinbinedwith a pair of rollers'for drawingthe paper along,

and with a device for perforating the paper, substantially as and for the purposes specified. In witness. whereof I have hereunto set my signature this 15th day of March, A. D. 1865.. I1. BRADLEY.
