METHOD OF MAKING OILING LINKS FOR DRIVE CHAINS.

UNITED STATES PATENT OFFICE.
STERLING ELLIOTT, OF NEWTON, MASSACHUSETTS.
METHOD OF MAKING OlLlNG-LINKS FOR DRIVE-CHAINS.
SPECIFICATION forming part of Letters Patent No. 447,814, dated March lO, 1891.
Application filed June 10, 1890. Renewed January 28, 1891. Serial No. 379,888 (No model.)
To all whom it may concern.-
Be it known that I, STERLING ELLIOTT, of
Newton, county of Middlesex, State of Massachusetts, have invented an Improvement in the Method of Making Oiling-Links forDrive- Chains, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.
In another application for patent, Serial No. 314,039, filed June 12, 1889,I have shown and described a drive-chain especially designed for velocipedes. The drive-ch ain there shown consists of oiling-links each made of a single piece of metal pierced trans-versly to receive pins, and also having a central transverse passage communicating with the pin-receiving sockets or end holes, which passage is supplied with a lubricant absorbent and connecting-links attached to said pins.
This invention has for its object to devise a method by which the oiling-links above referred to may be easily and cheaply made and the pin-receiving sockets be given a truly cylindrical bearing.
In accordance with this invention a block is cut oit of a rod or bar, oval or other suitable shape in cross-section to give a proper exterior shape to the link. Three cylindrical holes are then drilled through said block, one at each end for the pins and one between them. Other holes are then drilled transversely through said block to remove the material which is between the end holes to thereby form an elongated central transverse passage communicating with the end holes. The pins are placed in the end holes and the Inbricant absorbent placed in the central transverse passage, and the connecting-links are attached to the pins at opposite ends thereof in any usual manner.
Figure 1 represents an end view of the rod or bar from which the block is cut; Fig. 2, a plan view of one of the blocks; Fig. 3, a side view of the block shown in Fig. 2, having three holes through it, the two end holes constituting pin-receiving sockets; Fig. 4:, a side view of the block shown in Fig. 3, having the material between the transverse holes removed to form a central transverse passage between the end holes or pin-receiving sockets; Fig. 5, a plan View of a portion of a chain formed of the oiling and connecting links, and Fig. 6 a side View of the chain shown in Fig. 5.
In forming the oiling-links I out from a rod or bar of suitable shape in cross-section-as oval, for instancea block a. (See Fig. 1.) This block a is then bored transversely through it with three holes 2 3 4. The holes 2 4 form end holes or pin-receiving sockets and the hole 3 between them a portion of the central transverse passage. Thematerial between the holes 2 3 and 3 4 is then removed by drilling in the same manner, one hole only in each instance being necessary, as 5 6, (see Fig. 4,) although if the central transverse passage thus formed is very long several holes will be required. By forming the pin-receiving sockets ,in this manner a truly cylindrical bearing-surface is presented for the pins, which I have been unable to obtain in any other way.
In forming the chain the pins Z) are placed in the pin-receiving sockets and the lubricant absorbent is placed in the central transverse passage. The connectinglinks c are secured to the pins Z) byiupsetting the ends of said pins or in any other usualor suitable manner.
I claim- 1. The method herein described of forming oiling-links for drive-chains, which consists in drilling cylindrical end holes transversely through a block, and thereafter removing the material between said end holes, substantially as and for the purpose specified.
2. The method herein described of forming oiling-links for drive-chains, which consists, in cutting a block from a rod or bar, drilling end holes transversely through it, and thereafter removing the materialbetween said end holes, substantially as and for the purpose specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
STERLING ELLIOTT.
