Mam/E2555 042352121? 4 All/2m ETI-IAN I. DODDS, OF PITTSBURGH, PENNSYLVANIA, ASSIGNOR TO FLANNERY BOLT COMPANY, OF PITTSBURGH, PENNSYLVANIA.
BAR FROM WHICH BOLT-BLANKS ARE MADE.
Original application filed June 15, 1915, Serial No. 34,265.
To all whom it may concern:
Be it known that I, ETHAN I. DonDs, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Bars from Which Bolt-Blanks Are Made; 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.
My invention relates to an improvement in bars from which bolt blanks are made and is a division of application Serial Number 34,265 filed by me June 15th, 1915.
The invention consists in a bar from which flexible bolt blanks are cut, composed of a central member and two side members integral with the central member at one edge of the latter, the said side members being bent against the central member and the whole rolled into cylindrical shape.
In the accompanying drawing, Figure 1 is a view in cross section of the slab after its preliminary or first rolling; Fig. 2 is a similar view after it has been rolled into cylindrical shape, and Figs. 3 and 4 are views of a slightly modified form.
In the manufacture of the bar, I take a slab of any approved shape in cross section and pass it through rolls which transform it into a central member and two side members 6, the two side members being joined to the central member at one edge of the latter, so that the bar after this rolling is substantially T-shape in cross section. The central member 5 is rounded at its outer end as at 7 and the outer faces 8 of the two side members 6 are in the arcs of a circle, so that when the side members are folded against the central member, the bar will be cylindrical in shape. The side members are folded against the central member by rolling which also smooths out and straightens the bar, and the latter as thus formed, is provided with two longitudinal slots 9, both of which are open at one edge and closed at flopies of this patent may be obtained for five cents each, by addressing the Commissioner Specification of Letters Patent.
Patented Nov. 21, 1916.
Divided and this application filed September 14,
Serial No. 50,662.
the other. These slots are at opposite sides of the longitudinal center of the bar, and extend upwardly past the transverse center. After the bar has been thus formed, it may be twisted longitudinally from end to end so that thetwo slots 9 will be in the form of parallel spirals extending from end to end of the bar.
To make bolts from the bar, the latter is reheated and is fed to a machine which upsets the head and cuts off the blank. By twisting the bar from which the bolt blanks are cut, the twist will be constant and uniform from end to end, and consequently uniform in the blanks that are out from the bar. The upsetting of the heads welds the' walls of the slots at the heads but leaves the walls of the slots in the shank disconnected thus permitting the shank to give or yield, and as the metal between the bases of the slots and the outer surface of the bar is comparatively thin they may be ruptured by the vibrations to which the bolts are subjected thus disconnecting the members constituting the shank and rendering the latter still more flexible.
The construction shown in Figs. 3 and 4: is identical with that shown in Figs. 1 and 2 except that the central member 5 is upset at its free edge so as to slightly overlap or overhang the free edges of the side members as clearly shown in F 4.
Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is
A bar for bolt blanks composed of a central member and two side members integral with the central. members at one edge of the latter, the said side members being bent against the central member and the whole rolled into cylindrical shape.
In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
