MACHINE FOR BENDING METAL.
SPECIFICATION forming part of Letters Patent N0.3l3,4.59, dated March 3, 1885.
i Application filed June 10, 1884. (No model.)
.T aZZ whom it may concern,.-
Be it known that I, ALWILL URBAHN, a resident of Paterson` in the county of Passaic and State of New Jersey, have invented an Improved Machine for Bending Metal, of which the following is a full, clear, and exact description, reference being made to the accompanying drawings, in which- Figure lis a plan or top View of my improved machine for bending metal. Fig. 2 is a longitudinal vertical sect-ion of the saine, taken on the plane of the line c c, Fig. l. Fig. Sis a vertical cross-section of the same, taken on the plane ot'theline k It, Fig.,l, and showing the clamping-jaw open. Fig.4 is a similar section showing the clamping-jaw closed. Fig.
' 5 is an edge view of the metal to be bent; Fig.
6, a face vlew ofthe same, and Fig. 7 an edge View of said metal after it has been bent.
The object of this invention is to produce a machine for bending straps of metal such as that used in grated doors or windows; and the invention consists in combining with the frame or main block of the machine a transverse lever-jaw for holding the metal to be bent and a separate bending-lever carrying an attachment or projection for engaging the metal to be bent -and crowding it against another attachment or projection which is carried by the above-mentioned frame or block.
In the drawings, the letter A represents a block of metal or other substance, of suitable size and form, which block is adapted to be clamped by a vise to a bench, or may be a rigid projection on a table or frame; hence this block constitutes, in fact, the supportingframe of the machine. The upper face of this block A is level, excepting where the saine carries a projecting piece, B, which serves as an abutment for leaning the metal. to be bent against, and also furnishes the edge a, which determines the angle to which t-he metal is to be bent.
To the lower part of the block A is pivoted, by thehorizontal pin b, alever, C, which carries an L-shaped jaw or head, d, that eX- tends over the upper face of the block A, as is indicated in Figs. 3 and 4. To the end of the block Ais also pivoted, by a vertical pivot, e, a lever, D, the upper face of which is substantially on a level with the upper face of the block A, but which carries on its top a projectiornf, or bending-lug.
The piece of metal to be bent, which is shown at E in Figs. 5 and 6 and indicated by 55 dotted lines in Fig. I, is placed upon the block A and lever D, so as to be in contact substantially on one side with the projection B of the block .'*Aand on the other side with the projectionf of thelever D. This appears clearly from the strap E, which is shown by dotted lines in Fig. l, and more particularly from the straight wing or end piece, g, of said strap E, which is shown in said figure. rIhis being the arrangement and disposition of the metal, and holding it tight between the headv 7C d of the lever O and the projection B of the block A. The attendant next turns the lever D on its pivot e-that is to say, from the position which is shown by full lines in Fig. 1 into about the position which is shown by dotted lines in that figure. By this motion the projection fot' the lever D carries the wing or end portion, g, of the strap E against the obliquely-set face a of the projection B,
whereupon the end portion, g, willassume the 8c position indicated for it at h in Fig. l.
I am not confined to the use of an obliqueedged projection, B, on the block A, as the face a may be rounded or otherwise formed to produce the requisite angle or bend in the strap E. In fact, the projection B is secured by bolts i to the block A, and can be removed to allow another projection with a differentlyformed face to be putin its place, and in like manner the projection f of the lever D is fast- 9c ened by bolts j to the lever D, and can therefore be removed and replaced by another of different length, thickness, or form.
If the metal E to be bent is perforated before bending, as shown in Fig. 6, and if it is desired to aOe the angle with reference to its distance from one or the other of such per-Y forations, it is desirable to have a gage`-pin, Z, inserted in the projection B, as shown in Fig.
3, aspring, m, being placed behind said pin Ic to push it out of the projection B, as appears clearly from Fig. 3. The pin may then be z l y 313,4,59
put through the perforation of the strap E before the latter is bent; and yet, if an unperforated strap E should have to be bent, the pin Will be crowded against the spring m into 5 the socket provided for its reception in the projection B, and will not be in the way of such unperforated strap.
I claim- 1. The combination of the block A, having 1o rigid projection B and bendingface a, with the clamping-lever C, which is pivoted to the block A and carries the head d, and with the bending-lever D, which is also pivoted to the block A, and provided Vwith the rigid projectionf, substantially as herein shown and de- 15 scribed.
2. The combination of the block A, hav'ing rigid projection B, with the spring m, pin l, lever C, and lever D, the lever D having the projection f, substantially as described.
Y ALWILL URBAHN.
