UNITED STATES PATENT OFFICE.

JOHN BERTON ELLIOTT, OF CLEVELAND, OHIO.

METAL-BENDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 561,211, dated June 2, 1896.

Appli filed February 27, 1896. Serial No. 581 ,089. (No model.)

To all? whom it may concern.-

Be it known that I, JOHN BERTON ELLIOTT, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Metal-Bending Machines, of which the following is a specification.

This invention relates to metal-bending; and it consists in the peculiar construction and combination of parts comprising a handoperated tool or implement, substantially as hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is aplan view of the machine in working order with a bar of metal in place, the dotted lines showing the movement of the lever in the act Fig. 2 is a side view of the bending-joint of the machine. Fig. 3 is a vertical section of the same. Fig. 4 is a top or plan view of the machine open, the straight dotted lines showing the bed or holder for the bar that is to be bent. Fig. 5 is a view of a removable cap-plate which lies over the bending-joint seen at O in Figs. 1, 2, and 3.

A is a base or bed plate, which supports all of the working parts of the device.

B is a holder firmly secured to said base, having a longitudinal rib b on its upper surface.

B is a side plate bolted to the side of said holder, which, together with the rib 12, forms a groove in which the bar or rod to be bent is laid, as seen in dotted lines in Fig. 1.

D is a bendingdever pivoted to the base A at the end of said holder B.

- cl is a plate bolted in a recess in the end of holder and lapping over the pivoted end of the lever D, having a rounded end, and is an extension of the top surface of the holder over the joint of lever D.

O is a cap-plate of the same size and form as the plate d. It has a longitudinal groove 0, which lies over the rib on said plate d, and This plate lies over the plate has a hole 0.

d and its hole 0 over a center pin 0 in the joint of the lever D.

E is a block firmly secured to the lever D, close to the rounded end of the plate 0, and forms the bearing-surface against the bar or rod to be bent, and forces the bar around the center pin a as the lever D is moved around in the direction shown by the arrow and by the dotted lines.

Fis a short clamping-lever pivoted onto the block E, which is provided for holding the plate 0 down during the operation of bending the bar, as seen in Fig. 4. The long end of said lever B is supported on a block G on the bending-lever D.

The manner of working this device is as follows: The levers D and F being in the position seen in Fig. 4. and the plate 0 removed, now the bar to be bent is laid in the position shown by the dotted lines. Then the plate 0 is put in place and the lever F turned parallel with lever D. The bar thus occupies the space at between the two plates (1 and O. (Seen in Figs. 2 and 3.) Now, by carrying the lever' D around, the bar may be neatly and easily bent to any degree of curvature desired.

The machine maybe held by clamping the base A in a bench-vise or fastened directly to the bench."

Having described my invention, I claim- A metal-bending machine consisting of the base A, holder B secured to said base, a roundend extension-plate cl attached to the holder 13, a removable round-end plate 0, lying over plate 01 and the center pin 0 the lever D pivoted to the base A under the extension-plate d, block E on the lever D, and the lever F pivoted onto the block E, all constructed and adapted to operate substantially as and for the purpose set forth.

JOHN BERTON ELLIOTT.
