IMPROVMENT IN wooVD-BENDING MACHINES.

Specification forming part of Letters Patent No. 48,661, dated July 1l, 1865.

ings that accompany this specification, makingA part ofthe same.

The nature ot' my invention consists in bending wood by passing` it over rollers to give-it the desired form on one side and pressing upon the opposite side by a moving form operated by levers, said form also affording a ready means ot' releasing the bent piece of wood from the machine.

In the drawings, Figure 1 represents a side view of the machine, showing a piece of wood bent; Fig. 2, a front end view ofthe machine.

A represents thelegs of the machine; B, the frame or sides. U is a moving or sliding top, carrying the wood l), and having a small projection, c, at its rear end, against which the wood abats. By means ot' the cog-wheels E and F, crank G, and cord H, passing over pulley l, it will be seen how the sliding lop, with the wood, is carried forward between the rolls 'lhe rolls are held between l'ouruprights, b, giving two sets ot'rolls. There are also two formers, so that two pieces of wood can be bent at once. The upright pieces b or curved inclines can be changed, or the rolls in them, so that the curvature of the wood may be varied at pleasure by changing the position of the rolls. The forming-blocks J can also be changed, being screwed to the rotating center d, on or with which they oscillate, and this center, with the blocks, are carried by two oblique pieces, e and f, and they slide along another Astationary piece, g, held by uprights h h'. A pin, fi, passes through e andy f, works in a slot in g as a guide, having a head,j, to control the movement. These forming-blocks are raised and lowered by means of the levers L L' and their connections Z Z', these latter, Z',

'jl in their lower ends and guide.- screws s, so

that these several parts arc capable ot' varied adjustments.

rll-he operation is as follows: The table being run back, the piece of wood to be bent is laid thereon after being steamed, the rear end abutting against c, the front being laid on the first roller. Theformingblock J above is put in position over the wood, serving as a controlling gnide, and the required pressure brought to bear by means of lever L, which is held down by a ratchet or pins, s. The. continued turning ofthe crank carries the wood forward over the rollers and under the formers, giving it the bent shape desired. But'before the Wood is put on the sliding table a strap of metal, t,

' oscillate'd if necessary, the wood removed, the

machine being ready for another operation.

The small wheel F can be easily slid out of gear,`so that the table G may be run back more rapidly.

The construction of the shaping-blocks or formers is such (as will be seen) that the link l can be over the middle ot' the wood and on one side ot' the former J What, therefore, I claim asuew, and desire to secure by Letters Patent ot' the United States, is y The combination of the uprights I), carrying rollers a, the curved l'ormers J, and the sliding blocks ef, arranged and operated substantially as described, for the purpose set forth.
