UNITED STATES PATENT OFFICE.
FRIEDRICH ALBERT, OF NUREMBERG, GERMANY.
SCREW-STOCK.
SPECIFICATION forming part of Letters Patent No. 666,789, dated January 29, 1901.
Application filed september 29, 1900. Serial No- 31,572. (N0 model.)
To aZZ whom it may concern:
Be it. known that I, FRIEDRICH ALBERT, manufacturer, (whose post-office address is Nos. 9 and'll Mathildenstrasse, Nuremberg, Bavaria,) a subject of the King of Bavaria, residing at Nuremberg, Bavaria, Germany, have invented certain new and useful Improvements in Screw-Stocks 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.
The purpose of the present invention is to substitute for the screw-stocks now used for screw-threading dies made of massive wrought iron screw-stocks of sheet iron, sheet-steel, or similar formable material with exchangeable adjust-able nuts, as such weigh much less and are yet of sufficient stability.
In the accompanying drawings, Figure l is a partial section of the improved screw-stock. Fig. 2 shows a section on the line A A, Fig. 1; Fig. 3, a section on the line B B, Fig. 1.
As appears from the drawings, a blank a (shown in dotted outlines in Fig. 1 and corresponding to the ground form of the finished screw-stock) is punched out of sheet metal, and this has an elongated gap I) through its center, over which the dies may be adjusted. Hereupon the piece a is brought under the press and its ends turned up, so that the result is a case-like form. By the same action a socket e is pressed into the bottom of the screw-stock frame at in line with the elongated gap. This deepening is for the reception of the exchangeable adjustable nut f, Fig. 3, in
which the screw for setting up the dies works. In the further course of the manufacture the little side handles 0 are finished tube-like by the press, and, further, the sides of the frame d are drawn into a dovetail form, as shown in Fig. 2, in order to receive the correspondingly-formed threadbearers or dies. A part of the Wall of the frame must of course remain vertical in order that the dies 9 can be inserted and slipped under the dovetail.
The adjustable nut f is fastened in the socket e and can for this purpose be provided with one or several protuberances h, which fit into the openings 2 of the frame-bottom and can be bound to it by rivets, screws, &c.
What I claim, and desire to secure by Letters Patent, is
The screw-stock herein described, formed of sheet metal with tubularhandles,elongated central gap, dovetailed sides for the reception of the dies, and a socket for the nut in line with said gap.
In testimony whereof I affix my signature in presence of two Witnesses.
FRIEDRICH ALBERT.
