BENJAMIN F. RIX, OF KALAMAZQO, MICHIGAN, ASSIGNOR TO It. ARTHUR STONE, OF SAME PLACE.
MACHINE FOR FORMING VEHICLE-SEAT BARS.
SPECIFICATION forming part of Letters Patent No. 366,880, dated July 19, 1887.
Application filed April 26, 1887. Serial No. 236,164.
To aZZ whom it may concern:
Be it known that I, BENJAMIN F. RIX, aeitizen of the United States, residing at Kalamazoo, eounty of Kalamazoo, State of Michi 5 gan, have invented a new and useful Machine for Forming Vehicle-Seat Bars, of which the following is a specification.
This invention has for its object the construction of a machine for forming the seatro bars, from T-metal, of two-wheeled vehicles.
It also more especially has for its object to produce a device or machine for bending a bar of T metal toward the single flange (sometimes called the stem) ol'the T bar or rail.
In the drawings forming a part of this speeificatiou, Figure lis a plan view; Fig. 2, a section 011 lines 2 2 in Fig. 1; Fig. 3, a broken plan showing an equivalent to Fig. 1; Fig. 4,
a broken plan of parts in Fig. 1, and also showing parts below described; and Fig. 5 is a section on line 1 1 in Fig. 4.
In Fig. 1, D is a T-rail, and the dotted position of this rail. in said figure shows it bent into the ordinary shape of a seat-bar for vehicles. The part to which this invention more particularly relates is illustrated at the lefthand portion of Figs. 1 and 2, one being in tended as an equivalent to the other. It is a diliicult matter to bend the T-rail toward its Single flange a without a proper tool, form, or machine for the purpose, for the reason that the single flange would bulge when trying to bend it upon itself.
5 At Bis shown a bed-plate, to which the lever I, Fig. 1, is pivoted. This pivoted end is rounded on one side, and the lever is grooved from below the handle end of said lever to the lower end of said rounded portion, said groove 0 being a channel to receive the single flange c ofthe T-rail. An eccentric lever,t,is pivoted to the forming-lever I, to hold the end of the T-rail clamped firmly to said lover I, as in Fig. 1. A raised portion of the former at s 4 5 serves as a shoulder to contact the upper face of theT-rail. Now, by swinging the lever I to the position shown in dotted linesin Fig. 1 this end of the T-rail is bent or shown to form the seat-support at the rear end.
(No model.)
During the operation of bending it will be observed that that portion of the single flange e which is bent upon itself is in a groove just large enough to receive it, and hence it is prevented from bulging laterally. As an equivalent to this, I employ in lieu of the grooved lever I a fixed block, a, grooved, and corresponding in shape to the lower end of lover I. and a lever, A, pivoted so as to be clamped by the clamp and lcvcrwi to the upper face of the T-rail. By swinging the lever A down the T-rail will be bent as in Fig. 1, and during the operation that-portion of the single flange c whichis bent upon itself will be in the grooves of the block a, and hence cannot bulge laterally, thus the results in both in 6 stances are the same.
The raised curved portion (7 of the bedplate 13 conforms to the desired curvature of the body portion of the seat-bar D. It will be observed that this port-ion is bent away from the single flange c, as shown by the dotted rail in Fig. 1. This part of the bar may be bent by any suitable means. At Z) is a pinch-lever catching over the edge of the raised part of the former O, and recessed, as 7 5 at V, Fig. 2, to [it the shape of the T-rail. \Vith this lever the rail can be bent a little at a time around the form C.
The lever f, bearing the grooved wheel 0, Figs. 4 and 5, may be used in lieu of the lever b. A rope, r, is attached to the lever f, and is passed over a pulley and weighted at U. The pulley has a pivoted bearing, and the lever f is slotted or forked and straddles said bearing below the pulley, and is thus ful- S5 crumed to swing laterally. In the operation of swinging the lever f the wheel 0 traverses the T-rail flange, and the weight keeps the wheel in close contact around the entire curve of the portion 0 of the bed-plate B. 0
Having thus described my invention, what I claim is 1. A machine for bending the seat-bars of vehicles, which bars eonsistin T-rails, toward the single flange of the rail a bed-plate or suit- 5 able support, the fulcrumed lever having the groove to receive the single flange of the rail, or the described equivalents to said grooved lever, means for clamping the rail to the lever, stop to contact the flat face of the T-rail while and a shoulder or stop adapted to contact the bending the single flange upon itself, and suitflat face of the rail near the point of bending, able means for bending the body portion of 15 substantially as set forth. the T-rail around its form, substantially as 5 2.
