Letters Patent No. 102,641, dated May 3,1870.
IMPROVEMENT IN` BENDINGMACHINE The Schedule referred to in these Letters yPatent and making part of the same.
` tofore been attended with considerable diculty, es-
pecially when a round stick of such wood as maple is employed. rlhe shortness of the woody fibre ren# dered the handle liable to break, and only half round h ookshave been thus made, and thesewere not fully approved in the trade.
My invention is made with reference to the removal of these difficulties, and consists in a peculiar clamping and bending apparatus, that operates upon a round or otherwise nearly finished stick, togive to the vsamea compound curved or cross hook form, While clamped i n such a manner that there cannot be any endwise motion or yielding, but` the bending will ell'ect an end compression throughout the bent portion, whereas, in the bending-devices heretofore made, the stick was liable to be broken or split in consequence of. not being held sut'liciently to prevent an end motion while being bent by a compressing-strap In the drawing- Figure 1 is a plan of my apparatus; and
Figure 2 is a section at .the line x x.
'Ihe bd tt of the apparatus is made with a fence, l), to which the metallic bending-strap c is attached. Said bed a also carries the gudgeon d, upon which the clamping-molde swings.
The edge of this mold is grooved toreceive the cane' or stick f, and a projection at g is made, so that a compound curve or back-set is given tothe stick in the act of clamping said stick between the mold e, and bending-strap c. v
A pin, introduced at h,-holds the mold c in place while the bending-strap c and cane or stick are bent down to the mold c, and retained by a piu inserted at 7c.
It is to be understood that the mold e is to be heated, and the stick or cane rendered pliable by steam heat, and I find that, in consequence of the back-set and the compound curve thereby produced, Iam enabled to bend umbrellaand cane handles with the shape known as the cross hook, without breaking the fibre of the stick, because the compound curve and the firm hold of the cane by the ose't g ensure a uniform'endwise vcompression of the entire hook in bending it to shape, whereas, in the bending of semicircular hookson the handles, such hooks are liable to break.- l
One man has a sufficient supply of these bendingclamps toallow the stick or cane to remain in the mold a sufcient length of time to become dry and set before 11e comes around to that mold, as 'he operates them in succession.
lhe fence l) might be movable, and the mold c stational-y. l I do not claim the strap c, or bending-mold, as a variety of articles have been bent by devices ot' said character. l
I claim as my invention- -The mold herein described for bending canes o1" sticks, formed of the clamp c, with the projection g, in combi'nationwith the strap f, fence b, and bed a., the. parts being constructed and operated substantially as specified. y
Signed by me this 3d day of March, A. D. 1870. HENRY WINTER.
