UNITED STATES PATENT rricn.
BENJAMIN OBORN, OF MARION, ASSIGNOR TO JOSEPH ANDRE\V JEFFREY,
' OF COLUMBUS, OHIO.
DRIVE=CHAIN.
SPECIFICATION forming part of Letters Patent No. 378,173, dated February 21, 1888.
Application filed Apr-115, 1884. Serial No. 126,769. tModcl.)
To aZZ whom it may concern;
Be it known that I, BENJAMIN OBORN, of Marion, in the county of Marion and State of Ohio, have invented certain new and useful III1 provements in Drive or Sprocket Chains; and I do hereby declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.
Figure l of the drawings is a plan view, the Fig. 2 is an edge View of Fig. 1. Fig. 3 is an edge view of two links in position for coupling or uncoupling. Fig. 4 is an end view of the pintle. Fig. 5 is a side View of the pintie.
Like letters indicate like parts in all the figures.
The link is substantially U-shaped, and consists, essentially, of two side bars, A A, connected by a tubular end bar, B O, which is provided with a circular seat, I), for the pintle. The opposite ends, a a, are also provided with circular pintle-seats (Z (I, one of the ends having upon its outer face a recess, (2'.
D is the pintle, circular in cross section and of such size as to fit closely the pintleseats.
e is a flange or lip projecting from the pintle at or near one end, and is of such form and thickness as to enter the recess (1' and have its outer face practically flush with the adjacent portions of the side bar.
0 is a spur or lug projecting from the side bar in such position as to overlap and engage with the outer face of the flange 6 when the links of the chain are straightened out, it beflan e 6 bein seated in the recess (1 that 40 when the links are straightened out the flange will be turned around under the spur c of the adjacent link, so that the pintle cannot be removed when the links are at any angle to each other,which they will ordinarily assume when 5 at work. I
By preference I provide the side bars with reenforcing ribs 0 c, which project beyond the adjacent portions of the end bar to constitute these lockinglugs, as is plainly indicated at 50 the lefthand end of Fig. 1.
I am aware of Patent No. 376,325 to B. A. Legg, and do not claim anything therein shown; but
What I do claim is- In a drive-chain, the herein-described U- shaped link having side bars, A A, united by a tubular. end bar, one of said side bars being recessed, as at d, and having at its opposite end a lo 0 in combination with a intie D, on
having a projecting flange, 6, adapted to enter the recess (1 and engage with the lug c,
, substantially as set forth.
In testi mouy whereof I have signed this specification in the presence of two subscribing wit- 6 nesses.
