HENRY REYNOLDS, OF AURORA, NEW YORK.
IMPROVED MACHINE FOR MAKING CHAIN-LINKS.
Svpecitication forming part of Letters Patent No. 102,711, (la-ted May 3, 1870.
To all whom it may concern:
Be it known that I, HENRY REYNOLDS, ot' Aurora, in the county ot'Gayuga and State ot' New York, have invented certain new and useful Improvements in Machines t'or Cutting QE, Bending, and Shaping Links for Chains; and 1 do hereby declare the following to be a tull, clear, and exact description ot' the same, reference being had to the accompanyingdrawings, making a part ot' this specification, in which- Figure l represents a front elevation of the machine. Fig. 2 represents a side elevation thereof. Fig. 3 represents the trip-ping device detached from the machine, that throws the shaped link from the formen over which it is bent. Fig, 4 represents a horizontal section through the machine, taken at thered linea/m,1 of Fig. 1. Figs. 5 and 6 represent the bending and shaping rollers and their traversing carriages detached from the machine.
Similar letters of reference, where they oc-4 cur in the separate drawings, denote like parts of the machine in all of the drawings.
My invention relates to a machine for bending or shaping chain-links, which are after. Ward welded up into achain; and to enable others skilled in the art to make and use the invention, I will 4proceed to describethe saine with reference to the drawings.
A is a bed or base, upon which is mounted a pillow-block, B, with a horizontal slotted cross-head, C, secured to its upper end, these parts being made strong and rigid to support the operative parts ot' the machine.
On the base A there is a shaft, D, which may be driven by an endless belt or band extending from any first-moving power and passing around the pulley E. The shaft D carries a pinion, F, which works in the cogged gears G on the perimeter of a disk or cam-wheel, E,
supported by and turning on a journal, I, secured to the pillow-block B. In the face ofthe disk or wheel H there is aseries of cam grooves or ways for giving a regulated motion to the moving parts of the machine, as will be explained.
In suitable guiding-ways, a a, in the pillowblock B there is arranged a vertically-moving plate, J, which has upon it an adjustable gage, b, a die or former, c, an oblique groove, d, and a shear-cutter, e, Fig. 4, that works in connection with a stationary cutter, f, Fig. 2, for cutting oit' a blank from the rod or bar. The plate J has a stud, K, projecting from its rear, upon which a friction-roll is placed, that runsin the cam-groove K in the disk orv wheel H, which camway is so made as that the rotation ot the wheel H will cause the plate J to move up and down in the pillow-block.
In the cross-head or cross-frame C, on top of the pillow-blo;k B, there is formed a slot or opening, L, having at its center a projection, g, on the under side, and acorrespondng cutaway portion, It, on the upper edge, so that the friction-rolls M on the carriages N, that traverse in said slot or slots, (for there are two of them, one in each side piece.) may roll over said eminence g, for a purpose that will be explained. Each of the carriages N carries a grooved shaping and bending roll, O, and so arranged that they will pass by each other, as each one bends its end of thelinkorlink-blank over the former i, and each bending-roll O rides up upon the elevation or swell g, and bend down or around the two ends of thevlink. Upon the two carriages N are other rollersviz., those, P, which run in the slots L in the side pieces, C C, andare simply guiding and friction rolls, and those, Q Q, which extend into the cam grooves or ways B R in the face ofthe Wheel H, and which cani ways cause the two carriages to move toward and from each other in bringing up and carrying back their respective bending-rolls O.
The former z', which is of the shape and size of the opening in the links, is ot' steel, and securely fastened to the pillow-block B. 0n two sides of this former i. the forksl or projections j of the spring delivering apparatus S stand,
and as the delivery apparatus is moved by the studs 7c in the wheel H striking against the projection l of the delivery-plate and moving it outward, it throws oft' the bent link in a condition ready to be welded. I
The blank is cnt oi' from the rod or bar so as to leave a scarfed end; and when the two scaried ends are brought up together by the bending-rolls they lap past each other, so that they are readily'and uniformly welded by a lap-weld; but the sca-ris or oblique cuts of the bent-up link do not face each other. On the contrary, as shown underneath Fig. 4, the Weld is formed by contact of the backs of' thelinks, calling those the backs that are on the `opposite sides from the searfs.
m shows one of the pieces as eut oli' between the gage b and the cut-ters e f, and n represents said piece as bent np into a link and ready to to be welded.
The operation is as follows: The bar is fed in obliqnelyiin the groove d, Fig.' 4, until it reaches the gage b. The cutter e comes up and ents ol'the piece between itself and the fixed cutter f. The moving plate J, which has the cutter e as WellV as the die c upon it, takes the piece cut oand carries it 'up and bends it around the former i. The two grooved bending-wheels 0 now approach each other, and each lof them takes its end of the U-shaped piece and bends it over the top of the former, so that the two ends shall lap past each other and the scarfed ends on the outside. In this form the links are welded into a chain and a better weld attained than when the lap is made by the searfed edges. Y
lation to one another of the oblique holding groove', the cutters, the former, and the rolls, in virtue ot' which the ends ol' the bent-up link shall lap each other, so that the weld shall be on the round part of the rod and not on the searfed ends or surfaces, substantially as desrribed.
HENRY REYNOLDS.
