SENDING-MACHINE.
Specification of Letters Patent.
Patented J an. 19, 1909.
Application filed ma 5, 1908. Serial No. 480,961.
To all whom it may concern:
Be it known that I, LOUIS E. RICE, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in 'Bending- Machines, of which the following is a specification.
This invention is a machine for making angular bends in metal bars, rods and strips, and it is provided with one lever for clamping the work and another lever for bending the same, these levers being provided with adjustable blocks to accommodate different kinds of work.
The object of the invention is by improve- -ment to produce a superior machine of the kind, capable of being fastened on a post, wallor bench, and capable of adjustment to accommodate work of different sizes and to bend the same to any desired angle, and making a very useful and practical machine for metal workers generally.
The invention is illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the same and 2 is a side elevation.
Referring specificallyto the drawings, 11 indicates the back plate of the machine which may be fastened to a wall or post by bolts at the holes 3. Or it may be fastened horizontally on a bench, the plate 11 then forming the bed of the machine. The bending lever 1 is fulcrumed at 10 to the back plate, and carries an adjustable block 6 which is fastened to the lever by a bolt 8 extending through a slot 7 in the block, and the block is pressed behind by a screw 5 tapped through an ear 4 on the lever; and by means of the screw the block may be set up or adjusted to any position desired, and so held.
The forming block is indicated at 12 and fits in a sunken recess 21 in the plate, where it is held by a bolt 13. This block may be any shape desired. It is shown with one square corner and other corners rounded to various arcs. The work is clamped against the forming block by means of a slidable block 17 which is guided by a bolt 19 extending through a slot 18 in the block, and at the upper end of the block it has two cars 23 through which a screw 24 extends, the
screw being provided with an adjusting nut 22 between the ears. The head of the screw is connected by links 25 to the short arm 26 of a hand lever 2 which is fulcrumed between ears 27 on the back plate. The links and the lever form a toggle, by means of which the clamping block 17 may be raised or lowered.
A red 14 extends from-the left side of the base plate and is provided with a gage arm 15 adjustable along the same to various distances from the forming block.
In use, the levers are swung up to allow.
the work to be placed on the forming block. Then the lever 2 is pulled down, which clamps the work upon the former. The bendmg lever 1 is then swung around to the right and the foot 9 of the block 6 carried by-the lever bends the metal around the adjacent corner of the former block. The operation may be repeated at different places on the same piece of metal to produce any angle shape desired. The block 6 is adjusted to slze by operating the screw 5. The clamping block 17 is adjusted to size by operating the nut 22. Forming blocks of different shapes can be readily substituted by removing the nut of the bolt 13. Inasmuch as the lever 2 swings forwardly and the lever 1 swings laterally, the machine is finite handy to operate, and the workman oes not have to change his position to work both levers. When the lever 2 is pulled down to just beyond the center it will held without further power.
I claim:
The combination of a bed or back plate, a former'block thereon, a bending lever pivoted on the plate, a clamp block slidable on the plate toward and from the former block, a screw adjustably connected at one end to the clamp block, and a toggle connected betweenthe other end of the screw and the bed plate. one arm of the toggle having a projecting lever, for operation thereof.
In testimony whereof I affix my signature, in presence of two witnesses.
