BOLT-HEADING IMPLEMENT.

Specification of Letters Patent.

Patented Dec. 25, 1906.

Application filed May 3, 1904. Serial No. 206,231.

To all whmn it rncty concern:

Be it known that I, lVILLIAM H. SAYER, a

citizen of the United States, residing at Adams, in the county of Umatilla and State of Oregon, have invented a new and useful Bolt-Heading Implement, of which the following is a specification. This invention has relation to bolt-heading implements; and it consists in the novel construction and arrangement of its parts, as hereinafter shown and described.

The object of the invention is to provide an implement adapted to be used in combination with a vise for holding the bolt while the head is being formed upon the same. It is understood that during said operation the strain incident to the pounding is severe upon all implements used in such operation, and consequently the implements in order to be serviceable, must be constructed in a substantial manner and to be as free from weak points as possible. The forming of boltheads between clamping-jaws is unsatisfactory, for the reason that the blows exerted transversely of the holding force applied to the vise-jaws drives the bolt or rivet from between the same, so that it is frequently necessary to loosen the vise and readjust the bolt or rivet during the process of heading. This entails vexatious delays and annoyance and prevents satisfactory results and uniformity of the head.

WVith the improved implement hereinafter described the bolt or rivet is not only firmly supported and the tendency to longitudinal movement under the heading force materially decreased, but the implement itself may be effectually supported and held from displacement transversely of the clamping means. At the same time the implement is so constructed that the clamping means may be. applied on diametrically opposite sides of the pivot that secures the members which constitute the implement together, and thus the hinged or pivotal point of the said mem bers is relieved of the strain incidental to the force of the blows upon the end of the bolt. Furthermore, the implement may b e adjusted along its entire length between the jaws of a vise, and such adjustment is very convenient in the formation of heads upon the same characters of bolts.

In the accompanying drawings, Figure 1 is a perspective view of the improved implement. Fig. 2 is a transverse section, en-

larged, showing the device supported between vise-jaws.

The implement comprises the two members 10 and 11, hinged together at one end at 12 and with the other ends merging into the handles 13 and 14. In the adjacent faces of the members 10and=gl liare formed semicircular recesses 15 and 16, which when the members are united registerwith 'each other and form circular apertures to receive and support the bolts or rivets to be operated on and will be graduated in size to adapt them to difi'erent sizes of such articles.

The portions 10 and 11 of the implement are of the same size throughout their length,

so that their outer faces are parallel, and extending laterally from the upper outer edges are flanges or ribs 17 and 18, said flanges extending at thehinge end beyond the hingepintle. The flanges are desi ned to bear upon the clamping means, suc as the jaws of a vise. By reason of the fact that the said flanges extend beyond the hinge-pintle of the said members the clamping-jaws of the vise may be brought together diametrically opposite about said pintle, and thus the hingepoint or weak point of the implement is protected against the heavy strain incidental to the operation of forming the head upon a heavy bolt. This feature is material in preserving the integrity of the implement. Furthermore, by reason of the fact that the outer portions of the side surfaces of members 10 and 11 are in planes without shoulders or lateral projections the said implement may be shifted to any desired position between the jaws of the vise, and thus, if it is intended to form the head on a very long bolt, the rod may be placed in the recesses 15 and 16 and may extend down to one side of the vise. By reason of the fact that the said lower outer surfaces of the said members 10 and 11 are without lateral projections or shoulders the implement may be adjusted beyond either side of the vise.

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

An implement of the class described comprising members hinged together at one end and provided with handles at the opposite ends, said members having body portions of uniform width throughout and being provided in their inner edges with oppositelydisposed recesses, each said member having ICC on its outer-sideaflange thei ip, :er'surface of of: the hinged members, said membershaving which is in thesame plane ast face of the member, said flanges extend ng along the entire lengthrof: the members from points diametrically opposite the center of the hinge-pintle thereof to thefhanill'esthereof, those portions of the sides of the members vbeneathsaidflangestbeing in vertical planes without lateral projectionsor shoulders and the sides of the handles lying within the vertical planes of such under portionsof the sides 1 e'upper -sur' their hinged ends provided with arcuate surfaces which bear directly against each other.

In testimony that I claim the foregoing as r 5 my own I have hereto affixed my signature the presence of two Witnesses.
