SUPPORT FOR MOVING STOCKRODS.

Application led September 7, 1915.

To all whom it may concern.'

Be it known that I, LATHAM H. BRIGHT- MAN, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Supports for Moving Stock-Rods, of which the following is a specification.

My invention relates to the improvement of stock supports for nut making machines, and the objects of my invention are to provide improved supports for the stock or rod while the same is being fed into a machine which converts the stock into nuts; to so construct my improvedsupports as to prevent injury to the spool shaped bearings' thereof through the vibratory movement of the end of the stock rod when the latter is released from the spool.

Other objects of my invention will become more apparent after a further detailed description of the accompanying sheet of drawings, in which similar characters of reference designate corresponding parts, and in which:

Figure 1 is a view in elevation of two of my improved supports showing the end stock rod passing through one of said supports and with its rear end portion adjacent to the discharge end of the other support, Fig. 2 is an enlarged elevation of one of the supporting heads, and, Fig. 3 is a central vertical section of the same.

At desirable intervals and in proper alinement with each other, I provide upright standards or supporting rods 1, these standards being arranged on a line with the feeding mechanism of any suitable type of nut making machine. Upon the upper end portion of each of these standards 1 is mounted a supporting head, which comprises an upright socketed portion or shank 2 which is surmounted by a head 3, the latter being bifurcated or of yoke form as indicated in the drawing. The upper end portions of the standards 1 enter the hollow or socket portions of the members 2 and are adjustably held therein through the medium of suitable set screws 4t which pass through the bases of the members 2. Fixed in a suitably rounded recess in the crotch of the bifurcated head 3 vof each of said supports, is a semi-tubular bearing plate 5. Within the U-shaped space which is thus formed between the upwardly extending opposing Specification of Letters Patent.

walls of the member 3 and resting upon the bearing plate 5 of each of the supports is the central or barrel portion of -a spool 6, the latter' having flanged spool heads 6, Each of these spools s of somewhat greater length than the length of the bearing or the head 3 so that when one of the spool end flanges is against one end of the head, the other projects beyond said head, this being shown more clearly in Fig. 1 of the drawing. 'Ihe spool body is prevented from escaping from its seat within the bifurcation or head yoke by the insertion of a suitable pin 7 through opposing openings 7*L in the side walls of the head 3 above the spool.

In practice, the stock rod from which the nuts are to be formed and which is indicated at 8, passes through correspondingly shaped openings 6b in the spools 6, said spools thus supporting the stock. Although the opening shown in the spool in Fig. 3 of the drawing, is of hexagonal form in cross section, it is obvious that any suitable shape of opening may be employed to correspond with the form of the stock in cross section.

It will be understood that the rod or stock 8 is fed intermittently through the spools to the nut making machine by the usual or a suitable mechanism and experience has shown that where the stock bearing member, which in the present case is in the form of a spool, is of substantially the same length as` and held against longitudinal movement in the head 3, the end of the stock rod immediately after it leaves one of the spools is, owing to the length of the rod or that portion thereof which is suspended from the next forward head, subjected to an upward and downward vibrating movement, with the result that during a limited time, the .end of the stock rod strikes or scrapes the adjacent end of the spool and particularly the edges at the mouth of the opening in the spool, thereby damaging the end edges of the spool opening. In order to overcome this diiiiculty, I have provided the bearing spools 6, as described, of greater length than the length of the heads which support said spools. As the stock rod and the spool rotate together, it will be understood that the feeding action of the rod through the spool will by frictional engagement with said spool, tend to draw the latter to its limit in the direction of the feed,

2O Y. JJhe combination with a supporting head, of

I this position of the spool being indicated at the right in-Fig. l of the drawing. At the -rst vibratory movement of the end of the stock rod after it leaves the spool end, it is o obvious that any contact Voijthe rod and spool will serve to immediately drive said spool back until the adjacent flange 6a is against the end of theY head 3, said spool being thus moved out of the. Wayof the vi- 1o brating end of the rod and saved from dam- Y aging Contact therewith.

`lllthough I have described my improvement as being Vadapted or use 1n connection with nut making machinery, 1t 1s obviousV that the stock supporting means a stock supporting member slidably and rotatably mounted in said head, said sup- Gopes of this patent may be obtained for porting member being of greater length than Said head.

3. In a support for a moving stock rod, the combination with a standard having a bifurcated supporting head, of a stock supporting member slidably and rotatably mounted in said bifurcation, said member being of greater length than said head, and an opening through said stock supporting member corresponding in shape to the stock to be fed therethrough.

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