IMPRQ'VED DEVICE FOR HEADING BOLTS.-
The Sehedule referred to inthesfe Letters Patent and makingpart of the same.
To all whom 'it 'ma/y concern:
Be it known that I, JOHN M. WOODS, of Washington, in the county of Franklin, and State of Missouri, have invented a new and valuable Improvement in Bolt-Heading Machines; and I do yhereby declare that the following' is a full, clear, and exact description of the construction and operation of the same, reference being had to the'annexed drawings, makinga part oi' this specification, and to the letters and gures of reference marked thereon.
.Figure l of the drawings is a side view of my bolt heading machine;
Figure 2 is a front view;
Figure 3 is a Sectional view; and
l Figure 4 is a detail.
My invention relates to devices for fashioning bolts preparatory to cutting screw-threads thereon or otherwise; and
It consists in constericting a portable machine for that purpose, easily adjustable to an anvil or bench, and in which the bolts may be readily formed by novel and expeditious means.
The letter A of the drawings represents a vise, the lower end of which is adjustable to an anvil or bench, and .held rmly therein by means of the key a.
The jaws of this vise are marked b and c respectively, and they are held together by the bolts dand s,
in the manner represented. The bolt (l is hinged, as
shown, on fig. 4.
The letter 'u is a spring, adjusted between the jaws of the vise, as shown, and serves to force them asunder when the bolt is completed and ready for removal.
The bolt s has a shoulder upon one side of the vis'e, and a thread and nut at the other, as shown, between which the jaws have play adapted to the size of the dies in which the bolt is formed. 'r
On the long end of bolt s, I attach the lever O, by means of a hinge, as shown. This lever extends from the hinge above mentioned, to a point near the ground or floor, where it is formed to receive the operators foot and serve as a treadle. f
The upper end of lever O is bent around, as shown on iig. l, and formed in the shape of an arm, with its of which is affixed to each of the jaws of the vise, in
the manner shown, and they are removable at will.
The upper ends of these dies are made sharp and ush with the top of the jaws, or they may be reamed 1 out, as the operator desires. ,In the former case,'the lower end of the bolt-head will be formed iat, and in the latter it will be bevelled.
The letters 7: and xrepresent openings, one at the bottom, and the other in the side of the hollows that hold the iron rods, and they are designed 'as passages for the cinders, 85o., from such rods.
To operate my device, I first heat the rod of iron to a red heat in the iire, and then place it in the dies J. I then pressdownward with a foot upon the treadlebottom of lever O. This movement brings the bottom of elbow-lever t against the jaw c, and forceit, with great power, against the jaw b. 'By this means, the rod is grasped firmly by the dies.
I next strike'with a hammer upon the end of the A rod, above the dies, and thereby form a head thereon, of the size required. When-this is accomplished, the foot is withdrawn from the treadle, and the boltrex, for the removal of cinders, &c.,'and 'the foot-lever O, all constructed and arranged substantially as described.
In testimony that I claim the above, I have hereunto subscribed my name, in the pres ynce of two wit- AIIOSSOS.
