Application filed. August 9, 1913. Serial No. 783,916.

To (455 whom it may concern:

Be it known that I, WILLIAM W. CONNOR, a citizen of the United States, residing at De Bidder, in the parish of Beauregard and State of Louisiana, have invented certain new and useful Improvements in Conveyor- Qhains, of which the following is a specification.

My invention relates to a new and useful conveyor chain and more particularly relates to that class of chains which are employed to convey such material as sawdust, hay-dust, bark, slabs, strips, trash, etc.

The object of my invention is to provide a conveyor chain that will be given a much greater strength and durability than the chains now in use for a similar purpose by providing to each link of said chain a central member which will supplement the two outer members in transmitting a strain and carrying a load.

Another object is to provide a conveyer chain employing three separate sections to form each link, so that it will not be necessary to discard an entire link when one member thereof is broken, the broken member being simply replaced by a similar section in my construction.

Another object which I accomplish by the use of sectional links in my chain is to render it very easy to oil the rivets by which the links are joined.

A still further object of the invention is to provide a device of the character described that will be strong, durable, simple and effi cient and comparatively inexpensive to produce, also one in which the several parts will not be likely to get out of working order.

With the above and other objects in View, the invention has relation to certain novel features of construction and operation, an example of which is described in the following specification and illustrated in the accompanying drawing, wherein:

Figure 1 is a top View of a portion of my improved chain, three links thereof being shown. Fig. 2 is a side View of the same. Fig. 3 is a detail sectional view of the center member of one of the links, the section being taken upon the line XX of Fig. 1. Fig; 4 is a detail sectional view of an outer member of one link, the section being taken upon the line YY of Fig. 2.

Referring now more particularly to the drawing, wherein like reference characters designate similar parts in all the figures, the numerals 1, 2 and 3 respectively denote the three sections which together comprise each link of my chain. The central section 1 is substantially l shaped in form, one of its extremities being apertured as indicated at a to receive the rivet 5 by which the links of the chain are connected, a transverse sleeve 6 being formed upon the other extremity of said section to receive another ofthe rivets 5. 'lhe sleeve 6 is centrally slotted as indicated at 7. That extremity of each center section 1 which is formed with the aperture 4 is inserted within the slot 7 formed in the center section of an adjacent link of the chain. The outer sections 2 and 3 of each link are each formed at one extremity with integral sleeves 8 which are mounted upon the same rivet 5 that receives the sleeve 6 of the center section. At the other extremity of each section 2 and 3 there is formed integral therewith a boss 7 centrally apertured to receive the end portions of a rivet 5, said extremities of the sections 2 and 3 being made to inclose between them the sleeves 6 and 8 carried by the several sec tions of an adjacent link. The upper edge of the portion 1 of each center section will preferably be tapered to a sharp edge as is clearly shown in Fig. 3. Each of the bosses 7 will preferably be recessed as indicated at 9 to receive a washer 10 carried by the correlated rivet 5, the rivet-heads being made to bear upon said washers.

A conveyer chain having its links constructed as above described, will be sufficiently strong to resist any ordinary strain to which it may be subjected. In case however through any extraordinary shock one section of any link is broken, the chain will continue to perform its function being held together by the other two sections of the broken link. After the break has been noticed, it may be repaired merely by removing the broken section of the link and replacing it with a duplicate perfect section. In the present practice when any link of a conlveyer chain is broken, it is necessary to discard the entire link. It is to be observed that oil may be applied to the rivets 5 not only at their extremities but also between the sections comprising the links so that the entire length of it may be constantly kept perfectly oiled.

This formrof chain is particularly applicable for feeding sawdust and similar mate- =rial,to. furnacesbutthe device is not limited fto thisp'articular application.

7 7 claims; .i

to onelend, said sleeves being alined and constructed .to be united by a rivet the central section having an enlarged portion at theintersection ofits'sleeve and body, and

. it"s'sleeve having a cut away portion for receivingthe'central section of the next adj acent li k;

coiiie of this'patent may be obtained for 2. A chain comprising a plurality of links and rivets connecting the extremities of the links, each link being formed of three spaced parallel sections Which are formed With sleeves at one extremity of the link to receive the rivet correlated with said extremity, the center section With its integral sleeve being T-shaped and the two lateral sections with their integral sleeves being L-shaped.

In testimony whereof I have signed my name to thls specification in the presence of tWo subscribing Witnesses.

WILLIAM W. CONNOR.
