PERFoRA'rlNe-MACHINE.

SPECIFICATION forming part of Letters Patent No. 575,853, dated January 26, 1897.

Application led March 25, 1896. Serial No. 584,881.

T all whom, t may concern:

Be it known that I, EDWIN HARRIS BUFF- NER, acitizen of the United States of America, residing in the city, county, and State of New York, have invented a certain new and useful Perforatinglllachine, of which the following is a full, clear, and exaet specification.

The object of my invention is to provide a simple, convenient, and easily-operated ma- Io chine for making perforated patterns and for similar purposes which can be readily attached to and operated in connection with a sewing-machine or in connection with a pulley upon a shaft turned by machinery or power.

Referring to the drawings which illustrate my invention, and which form a part of this specification, Figure l is a view, partly in perspective, showing my improved perforating- 2o machine attached to a sewing-machine. Fig. 2 is a detail sectional view of the bracketpiece for supporting` the flexible shaft and which also carries the dri ving-pulley and supporting-arm. Fig. 3 is aside elevation of the 2 5 perforating-pen and handle. Fig. 4 is acentral sectional view of the perforating-pen and a portion of the flexible shaft. Fig. 5 is a detail view of the pen shown in Fig. 3, looking' in the direction of the arrow shown in Fig. 3.

3o Referring to the drawings, A is a sleeve provided with a set-screw A'. This sleeve is adapted to fit upon the spool-carrier B of any ordinary sewing-machine, as B', and to be secured thereto by the set-screw A. At the 3 5 upper end of the sleeveA is an arm O, which extends outwardly and over the drivingwheel D of the sewing-machine. A sleeve E fits upon the arm O and may be secured thereto at any desired position by the set-screw E.

4o To the sleeve E is attached an arm F, to the lower extremity of which is secured a bracketpiece F', which is adapted to receive and carry a pulley G, which is preferably provided with a soft-rubber rim G'.

The bracket-piece F'is provided with suitable bearings f'fand receives and supports one end of the flexible shaft H, upon which the pulley G is mounted, as shown in Fig. 2. The flexible shaft H may be of any usual or 5o desired construction and is preferably a coiled spring-wire H, surrounded with atextile cov- (No model.)

ering` H'. Upon the other extremity of the exible shaft H is attached the perforatingpen J. This perforating-pen consists of a face-plate K, which is provided at one side with a tang Kf, which is adapted to be secured in the handle K2, which is preferably formed like an ordinary penholder.

Upon the extremity of the flexible shaft H is mounted a cam O. The cam O works in 6o and is adapted to operate a vibratory frame P, Which is retained in position upon the face-plate K by the strap L, which is secured to said face-plate by screws Z/ or in any other suitable manner. At the bottom of the vibratory frame P is attached an ordinary sewing-machine needle R, which Works in the bearing fn, formed in or upon the lower edge of the face-plate K. At the upper part of the vibratory frame is a pin T, which Works in 7o the bearing m, which is formed in or upon the upper edge of the face-plate K. This pin T, working in its bearing m, serves to prevent lateral movement of the vibratory frame P and the ordinary sewing-machine needle R. As the cam O is rotated in the operation of my machine by the flexible shaft H the vibratory frame is caused to vibrate-rapidly 'up and down and to cause the needle to be vibrated in unison therewith. 8o

At the loweredge of the face-plate K, I form a spur S, which is adapted to act as a guide or rest, it being held upon the paper to be perforated by the operator using the machine.

In carrying my invention into operation the sleeve A is secured by the set-screw Al to the spool-carrier B of the sewing-machine in such a position that the arm O will extend over the fly-wheel D of the sewing-machine. 9o The sleeve E, carrying the arm F, is then adjusted upon the arm O in such a position that the pulley G will be over and in line with the driving-Wheel D and is secured in this position by the set-screw E', the pulley Gr being 95 pressed down against the fly-wheel D. When the fly-wheel D is revolved, it will rotate the pulley G by frictional contact, and thus communicate motion to the flexible shaft H and the cam O, which, as it turns, causes an uproo and-down motion of the vibratory frame P and causes the needle R to be rapidly moved up and down in the bearing n, the point of the needle R extending suliciently below the bearing N when the vibratory frame P is in its lowest position to perforate a piece of paper or other substance upon which the needle R may be placed and held. by the operator.

The operator holds the perforating-machine by means of the handle K2, which is held in the operators hands in the same manner as a pen or pencil, the spur S resting upon the paper or other substance to be perforated and acting as a guide or rest.

If desired, the needle may be made hollow and its lower extremity formed with a cutting edge, so as to operate as a punch, and, instead of making pin-hole perforations, to cut out considerable portions of the body of the paper or cloth and make very large perforaticns.

` It will be obvious that instead of supporting the sleeve A and connecting mechanism upon the spool-holder oit' a sewing-machine it may be supported upon an independent standard placed in proper position relative to the fly-wheel D of a sewing-machine or any other pulley or fly-wheel driven by machinery.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In combination, in a perforating device, a faceplate formed with a spur and a handletang extending laterally therefrom, a reciprocating frame placed upon the face of the plate, guides on the plate for the frame, said frame having an open center and carrying the needle, the eccentric therein and the shaft extending through the face-plate and carrying the eccentric, substantially as described.

2. In combination a face-plate having upper and lower guides, an open frame having the tool passing through one guide and a pin extending through the other guide, an eccentric working in the open 'frame and having its shaft extending through the faceplate and the strap L extending across the open frame and the eccentric, substantially as described.

3. In combination, with a sewing-machine having a spool-support B, a bracket C, having means vfor attachment to the said support and extending laterally therefrom, the depending arm F, the bracket F at the lower end thereof, the wheel D of the sewing-inachine, the shaft journaled in the bracket Il" and having a wheel G to bear on the sewinginachine wheel D to be driven thereby and the tool carried by the shaft of the wheel G, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

EDWIN HARRIS RUFFNER.
