SPECIFICATION forniing part of Letters Patent No. 780,561, dated January 24, 1905.

' Application filed April 20, 1904. Serial No. 203,976. l

To all whom t may concern: f

Beit known thatI, MOSES G. GANS, acitizen of the United States, residingat Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Punching- Machines, of which the following is a specification.

This inventionl relates to a ferrule-attaching machine. l

One object of the invention is to provide aL lupper part of the machine constructed in ac Fig. 6 illustrates an end of an umbrella and shows the ferrule or thimble secured in position on the rod.

ln the drawings, a designates an L-shaped bracket one side, c, of which extends in a horizontal plane and in the present instance (see Fig. 3) is bolted to a bed or table while the other side, a2, of said bracket extends vertically and is provided with a plurality of sockets or mortises c, which extend or are arranged in a horizontal direction near the upper edge of said vertical side c2. In the pres ent instance acup-shaped shell sts into each of the said sockets, and said shells are each provided with a perforation s in its side.

These perforations in the several shells vary ,in diameter, the largest perforation'pret'erably being at one end and. the next smaller adjoining and the others successively smaller comi-ng in their order.

A rectangular movable frame d has position.

at the rear of the vertical side fof the bracket, and said frame is held in position by two vertical end bars e and inwardly-projecting plates e'. In Fig. 1 the inward-projecting plate at the left side is omitted. This frame Z is arranged to have vertical movement at the rear of and with respect to said cup-shaped shells s. The vupper horizontal bar d of said frame d is provided with a plurality of downwardlyprojecting pins (Z2, each ot' which projects downwardly at the rear of one oi the perfolrations s of the shells. These pins are pointed at the ends and are preferably of a screw form and are screwed down through the top of said bar el, and the pointed ends project at the bottom. Horizontally-extending screws (Z3 are entered in the vertical side of the bar CZ and impinge against the pins Z2 and aid in keeping the said pins rigidly in place.

. An outwardly-projecting center pin f is secured in the vertical rear side of the top bar d of the frame, and a iiat spring f extends By this arrangement of pins and' plurality of upward-projecting pins g, each of which is directly beneath one oi' the upper pins d2. These lower pins are also provided with pointed ends and are held against displacement by horizontally-extending screws g2. A center pin L is secured in this bar g, and a at spring 7L extends horizontally above said center pin /L and has its ends curved downwardly, so as to pass beneath a stationary pin /f on each ot' the side plates e. By this construction it will be seen that the bar g is kept normally pressed down or away from the top bar ZC Two cams t' are pivotally secured to the vertical side a2 of the bracket a, and said cams have position between the lower side of the movable bar g and the upper side of the bottom cross-bar Z5 of the movable frame d. These two cams operate to press bar g upward and bar d downward.

Links j are pivoted eccentrieally at one end to each of said cams, and the lower ends of said two links are connected to the upper end of a rod j. A pin extends through the lower1 ends of said links and rod y", and said pin also projects through a slot 7c in the vertical depending bracket Z, which slot serves as a guide 'for said pin and also as a stop acting on the pin to limit the downward movement of the links.

The lower end of the rod j is attached to a treadle fm, by means of which the rod and links j may be moved vertically to partly rotate the cams f/. A spiral spring m serves to keep the treadle normally elevated.

Two stationary pins a have position beneath the movable frame (Z and serve as stops for the latter. f

In the operation of attaching` a ferrule or collar 0 to an umbrella-rod p the collar is iirst slipped over the lower end of the said rod, and said end is then inserted in one of the cup-shaped shells s, with the rod and collar projecting through the perforations s and having position between the two pointed ends Z2 and g The pointed ends of said pins thus have position at diainetrically opposite sides of said rod and collar. The treadle m is now suddenly depressed, pulling the rod j" and links j down with it. This downward movement of the links causes the cams '11 to be parti all y rotated, and as the narrower sides of the cams arein cont-act with the lower side of the movable bar g and the upper side of the bottom cross-bar d when the cams are turned the bar g will be raised and the frame d will be lowered, which causes the pins Z2 and g to make prick-punch indentations r on diametrically opposite sides of the collar, which indentations take into the rod p and secure the collar in position.

Then the treadle is released, the spring m will raise the treadle and rod j." and rotate the cams t' in the reverse direction, and Hat springs f" and /t will return the frame and bar f/ to their normal spread-apart positions andrelease the rod p.

It will be readily understood that the several pertorations s ot different diameters are provided in order that the one machine may accommodate umbrella-rods or canes elE various diameters.

Having thus fully described my invention, what I claim as new, and desire to `secure by Letters Patent, is-

1. In a machine of the class described the combination with an open frame provided with a pin, ot' a bar movable within the opening in said frame and also provided with a pin, and means for moving the open frame in one direction and also moving` the bar within the frame in a different direction to direct the pins toward a common center.

2. In a machine of the class described the combination with a bar provided with a pin, of a frame surrounding the bar and n'iovable with respect to said bar and also provided with a pin, and means interposed between the frame and bar for changing their relative pe` sitions.

3. In a machine of the class described the combination of a plate provided with a per foration; a frame extending around said perforation and movable at one side of said plate and carrying a pointed pin; a bar also carry` ing a pointed pin and inclosed by and mov` able within said frame and a cam device between the said frame and bar and arranged to act on both simultaneously to move them in opposite directions.

4. In a machine of the class described the combination with a perforated plate, ol a frame at one side of said plate and having parallel bars which extend respectively at ep posite sides or' the perforation in said plate and one ot said bars having a pin; a bar in terposed between the parallel bars o1 said frame and also carrying a pin, and a cam operating between said interposed bar and one of the bars of said frame to change their rela tive positions.

5. In a machine of the class described the combination with a plate provided with a phi` rality of perforations` ol parallel bars at one side of said plate and extending respectively at opposite sides of the center of said perlorations, said bars having pins projecting teward the center of said perforations, and means for drawing the bars together.

6. In a machine of the class described the combination of a plate provided with a perforation; a frame lnovable at one side ol said plate and carrying a pointed pin; a bar also carrying a pointed pin and movable with respect to said frame; a cam device interposed between the frame and bar for moving them toward each other, and springs for moving the frame and bar away from each other.

7. In a machine of the class described the lOO IOS

between said parallel bars and also Carrying pins, and a cam mounted on the perforated plate between the frame and the movable bar within the frame. 1 0

In testimony whereof I aflx my signature in the presence of two witnesses.
