HORN FOR PEGGlNG-MACHINES.

SPIEl-GIFIOATIUN forming part of Letters Patent N 0. 667,928, dated February 12, 1901.

Application filed October 23, 1900. Serial No. 34.065. (No model.)

To all whom, it may concern.-

Be it known that I, JOHN E. BICKFORD, of Whitman, in the county of Plymouth and State of Massachusetts, have invented a new and useful Improvement in Horns for Pegging-Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to that class of horns that rot-ate and are provided with means for cutting off the projecting ends of the pegs; and it consists in the peculiar mechanism used for producing the result desired, the object being to make a simple and effective mechanism for supporting the boot or shoe and for cutting the pegs. This object I attain by the means illustrated in the accompanying drawings, in which- Figure 1 is a view partly in vertical section and partly in elevation. Fig. 2 is a crosssection taken on line 2 .2 of Fig. 1. Fig. 3 is a plan view of the knife. Fig. at is a side view of the knife, a part being shown in section.

In the drawings a part of the frame of the machine is indicated by A A, and the post, which supports the horn, is designated by P. This post does not turn, but may be raised and lowered. The horn B B B is mounted upon the post P and is free to rotate upon it. The upper end of the horn has a stationary knife B which fits onto the end of the horn, as shown, and is secured by the screw B. A peg-hole b is made in the knife B This hole is beveled, so as to present a knife-edge to the peg. The lower knife is indicated by K, Figs. 1, 8, and 4-. This knife is adapted to fit closely to the under side of the stationary knife B and has a hole It, also beveled, as shown, so that as it slides it, together with the stationary knife B will cut the peg with a shearing cut. This arrangement of the stationary knife B and the moving knife K insures an exact easy action of the k nives,which results in cutting out the pegs in a thorough manner. The moving knife K is operated by the following-described mechanism: A bent rod D D has a pin .D at its upper end, With which the knife if by its hole K engages, so that any movement of the bent rod D D will be transmitted to the said knife. The bent rod D D slides up and down in a groove made in the horn (see Fig. 2) and is held in place by the plates E E.

The lower end D of the rod D D is connected to a rod R by means of a nut R and check-nut B A spring S serves to press the bent rod D D upward. The lower end of the rod R has rigidly attached to it a forked arm R R upon which a friction-roller R is mounted. The roller R rests upon the camsurface of the fixed cam C, so that byswinging the arm R a vertical movement will be imparted to the rod R and through it to the bent rod D D and thence to the knife K. The cam O is rigidly attached to the post P by means of the set-screw O and moves with the said post and also with the horn in vertical motion; but the horn is free to rotate independently of the post and the cam C.

To give the forked arm R a swinging motion, I have a lever L L, which has an adjustable fulcrum-pin L which is held to it by the nut and check-nut L The fulcrumpin L is attached to an adjustable slide L which is adjustably attached to the fixed arm A of the frame A of the machine by a bolt L which passes through a slot made in the slide L Motion is imparted to the lever L L by a lever N, which is operated by a cam on the pegging mechanism of the machine. The lever L is made adjustable in order to allow for the wear of the parts as the machine is used.

The vertical part L of the lever L L is made long so that the downward movement of the post and horn, necessary for putting on and taking off a shoe, will not disengage it from the fork R of the forked arm R R The sliding knife K may have a straight cutting edge and the hole It be omitted, if desired.

I claim-- 1. A born for pegging-machines comprising a knife for cutting off the pegs: mechanism for connecting said knife with a swinging arm: and said swinging arm: a cam fixed upon the horn-supporting post of the machine and having an inclined surface which will cause the said swinging arm to be vertically operated thereby giving motion to the knifeoperating mechanism substantially as and for the purpose set forth.

swinging arm: and mechanism for operating said adjustable lever substantially as and for the purpose set forth.

In testimony whereof I have signed my 15 name to this specification, in the presence of two subscribing Witnesses on this 13th day of October, A. D. 1900.

JOHN E. BIOKFORD.
