UNITED STATES PATENT OFFICE.

THOMAS C. HENDEY, OF TORRINGTON, CONNECTICUT, ASSIGNOR OF ONE-HALF TO THE COE BRASS MANUFACTURING COMPANY, OF SAME PLACE.

SWAGlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 439,952, dated November 4, 1890.

Application filed August 11,1890.

To whom it may concern:

Be it known that I, THOMAS C. HENDEY, a citizen of the United States, residing at Torrington, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Swaging-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in machines for swaging and pointing wire, and similar uses, and the particular objects of said invention are to secure a simple and accurate means for adjusting certain of the parts so that any wear may be taken up; and with these ends in view said invention consists in the construction and combination of elements hereinafter fully and in detail explained, and then recited in the claims.

In order that those skilled in the art to which my invention appertains may fully understand its construction and operation, I will describe the same in detail, reference being had to the accompanyingdrawin gs,which form a part of this specification, and in which Figure 1 is a front elevation with the faceplate removed; Fig.2, a vertical longitudinal section at the line y y of Fig. 1; Fig. 3, an end elevation of one of the compressors; Fig. 4, a side elevation of one of the compressors; Fig. 5, a section at the line w w of Fig. 4.; Fig. 6, a section on the line 0 o of Fig. 3; Fig. 7, a face view with the ring and compressors removed; Fig. 8, a face view with the com pressors removed.

Like numerals denote the same parts in all the figures.

1 represents a standard or base adapted to carry the moving parts of the machine.

2 denotes a shaft having a head 3 upon one end and a band-wheel 4 on the other end, whereby said shaft may be driven. Within a slot cut across this head are arranged dies 5 and hammer-blocks 6, having rolls 7. The construction of this head and the parts 5, 6, and 7,1 have fully shown and described in a 50 certain application executed by me upon an even date herewith, Serial No. 861,707, and it Serial No. 361,708. (No model.)

is therefore unnecessary to set forth their specific construction herein, since they form no part of my present invention;

In the face of the standard 1 is formed a circular recess, whose shape and dimensions are clearly shown at Figs. 1 and 2. In this recess is set a ring 8, so fitted as to be capable of rotation therein, and the inner edge of this ring is provided with a considerable num- 6o ber of cam-surfaces 9, each surface being sectoral but eccentric to the periphery of the ring. Inside this ring is a second ring 10, which is formed on or secured to the standard in any desired manner. I refer to this as a ring, and it may be convenient to make it as a separate part; but it may equally as well consist of a circle of sectoral projections formed on the metal of the head itself. This ring 10 has a considerable number of radial seats having parallel walls, said seats being shown as fourteen in number, which, however, is obviously immaterial, save that for the operation of the machine said seats should be arranged in opposed pairs. Each one of these seats is adapted to contain a compressor, which consists, as shown in Figs. 3,

4., 5, and 6, of two blocks 11 and 12, adapted to have a rocking movement relative to a shaft 13, which is secured to one of the blocks by means of a washer 14., and is adapted to engage with its end another washer 15, secured to the other block. This, when the parts are assembled, constitutes a simple and convenient bearing between the parts 11 and 12.

Each of the blocks 12 has a seat in its lower end, in which is mounted a roll 16, whose periphery projects beyond the face of the block, as shown at Fig 3. Upon its circumference 9c the ring 8 is provided with teeth 17, which are engaged by aworm 18 on a shaft 19, which is journaled transversely in the upper end of the standard. Said shaft at one end 20 is adapted for engagement by a key, and at its other end a set-screw 21 or a similar device engages it for the purpose of holding it as against rotation. Said ring has also a pinand-slot connection 22 with the standard, whereby its movement is limited.

The operation of my invention is as follows: When the compressors are arranged in their respective seats, the outer ends of the blocks 11 abut against the cam-surfaces 9, which are formed on the ring 8. The rolls in the inner ends of the blocks 12 are adapted to engage and operate the dies 5 through the rolls 7 in the same manner as the corresponding parts in the application heretofore referred to. When, however, for any reason it is desired to change the operative engagement between the rolls 7 on the head and those in the compressors, the ring 8 is turned slightly in the recess in the standard by means of the worm on the shaft 19, whose set-screw has been loosened for the purpose. By this movement the compressors are each carried inward to the same distance and are supported from the rear by a difierent and somewhat higherpart of the cam-surfaces 9. The nature of the joint between the blocks 11 and 12 insures at all times a full surface contact between the curved face of the block 1 1 and the cam-surface. The face-plate 23, when in position, prevents the displacement of any of the blocks in the ring; but in order to hold said blocks as against any inward sliding movement in their seats I perforate the faceplate immediately over each of the blocks 12 and insert in each perforation a bindingscrew 24, between Whose inner end and the block I interpose a washer 25 of leather or soft metal, which by its frictional contact will prevent accidental displacement of the blocks, but whose grasp upon the latter is not sufficient to prevent their being moved inward by the cam-surfaces when the ring is turned.

In this invention I do not wish to be 0011- fined to the precise construction which is herein shown and described, since the details thereof may be varied in many particulars, and still the spirit and aim of my invention be retained.

I claim 1. In a machine of the character described, the combination, with the standard, of a ring provided with cam-surfaces set in said standard, means for effecting axial movement of the ring, and a series of compressor-blocks whose outer ends abut against said cam-surfaces, substantially as described.

2. In a machine of the character described, the combination, with the standard, of the ring having interiorly-formed cam-surfaces, and means for rotating said ring, a series of seats in the standard, and a series of compressor-blocks set in said seats and adapted to be adjusted therein by the cam-surfaces, substantially as described.

3. In a machine of the character described, the combination, with the standard, of the movable ring provided with interior cam surfaces, a series of radial seats concentric with said cam-bearing ring, and compressor-blocks, each provided with a roll in its inner end, arranged in said seats and adapted to be adj usted by the cam-surfaces.

4. The combination, with the concentric rings 8 and 9, the latter provided with seats, of a series of compressors, each formed of two blocks havingarocking-bearing between them and arranged in the respective seats.

5. In a machine of the character described, the combination, with a suitable part having radial seats, of a series of compressors, each consisting of the blocks 11 and 12, having a rocking-bearing between them, rolls carried by said blocks, and means, as described, for effecting the radial adjustment of the compressors in their seats.

6. In a machine of the character described, the combination, with the standard, of the rings 8 and 10, the transverse shaft engaging and adapted to turn said ring 8, the compressors arranged in said ring 10, and friction devices engaging said compressors and adapted to retain them as against displacement.

7. In a machine of the character described, the combination, with the standard, of the rings 8 10, the radially-movable compressors, means for adjusting them, the face-plate, and friction-screws passingth rough said face-plate and engaging the compressors, substantially as described.

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

THOMAS HENDEY.
