CHAIN convnynn. I

i 7 a lication fiieaJul 15, 1926. Serial No.- 122,551.

My invention relates to chain conveye rs and more particularly to means for attaching the carrier to the chain.

Difficulty has been experienced in disconnecting the links of a c-onveyer chain at the point where a carrier was connected to the A further objection to the old attachment is that it frequently became loose and not being detected, soon became worn beyond further use. v The objects of my invention are to provide carrieratta ching means for conveyer chains which,when applied to a-chain link, will allow the links to be readily disconnected and ,will be free of liability of be coming loose on the link, thus lengthening the life of the conveyer and avoiding costly delays due to break-downs and repairs.

These objects, and other advantageous ends which will be described hereinafter," I attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is a fragmentary plan View ,of

a conveyer chain employing my carrier attaching means, I

Figure 9 a section on line 99 of Figure 8. Referring to the drawings, 1 indicates a chain which is of the type requiring shifting of the links toward each other to effect This atmembers 28 fit.

a disconnection of the outer links frmnthe inner link 3, which are connected by a pin elpassing through slots 5 in'the, ends of the links, Each slot has its inner end 6 enlarged and a semi-circular bearing 7 in its outer,- end. Journals 8 on pin 4 fit in bearings 7 and heads 9 on the ends of the pin, being of greater diameter than the widthxof the' slot, prevent endwise shifting of'th-e pin out of the links, and being of less diameterthan the'enlarged ends 6 of the slots, may be readily slipped out of the links through the aligned enlarged ends, after the links have been shifted toward each other tobri'ng the enlarged ends into alignment.

My carrier attaching means is connected to the inner link3 and is of such construction as will allow free shifting of the link to effect a disconnection. Saidmeansinclude a recess 10 on each side of the inner link and tenons projecting from the link in each recess. One-pair of tenons 11 is located in a horizontal plane in each recess and another pair of tenons 12 is located in 30 a vertical planein each recess. A carrier attaching member 13 fits in the recessand has mortises fittingthe tenons. One pair of mortises 14 snugly fit the horiontal faces 15 of tenons ll and another pair of mor- 35 tises 16 snugly fit the vertical faces 17 of tenons 12. Fitting the mortises on the tenons in this manner avoids accurate workmanship in positioning the mortise-s and tenons and yetenables a snug fit of theimortises and tenons to rigidly hold the carrier attaching member to the link. The side extensions 18 of the carrier attaching member are of such thickness that, when in the recess, their outer sides 19 are substantially flush with the outersides 20 of the. inner links as shown in Figure 1. This allows the outer links 2 to be shifted toward the inner link 3 past extensions 18 and tenons :12 when disconnecting the links. Each member 14 is secured in the recess preferably by bolts '21 passing through the link, and has an upwardly project-ing lug 22 to which a carrier, such as a flight 23, is secured. Other means may be substituted for the lug which best suit for securing the type of carrier used with the chain.

In the form shown in Figures 8 and 9,

an inner link 25 has a mortise 26 on each side in which tenons 27 of carrier attaching A carrier 29, such as a flight, is secured to the members 28 preferably by bolts. The means for connecting the links differ from the means shown in Figures 1-6 in construction only; the manner of disconnecting the links being the same, that is, the outer links 80 are shifted toward the inner link 25. Instead of making the pin as shown in Figures 1-6 free of the links, the pin 31 is made integral with the inner link 25 and has journal parts 32 fitting slots 33 similar to slots 5. The outerv links may be shifted toward the inner link for disconnecting the links without interferei'iee from the carrier attaching members .28, the outer sides of tenons 27 being substantially flush with the sides of the link.

In a conveyer chain employing the carrier attaching means above set forth, the links may be readily disconnected because the can rier attaching members 14 have their extensions 19 flush with the sides of the inner link. This allows the outer links to be shifted toward the inner link to effect a disconnection. The carrier attaching members 14 are rigidly connected with the link due to the mortised connection therewith and in use are practically free of the possibility of becoming loose, thus lengthening the life of the conveyer and avoiding shut-downs for repairs.

. While I have described my invention as taking a particular form, it will be under stood that the various parts may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a chain conveyor, a link; a pair ofjecting from the opposite sides of the link; a carrier attaching member secured to each side of the link and having mortises fitting the tenons; a lug on each member, and a carrier secured to the lugs.

41:. In a chain conveyer, a link; tenons projecting from the opposite sides of the link; a carrier attaching member secured to each side of the link and having mortises fitting the tenons, one mortise snugly fitting only the horizontal faces on one tenon and another mortise fitting only the vertical faces on another tenon. and a carrier secured to the members.

5. In a chain conveyer, a link having a recess between its ends at each side; tenons projecting from the link in the recess; a carrier attaching member secured in each recess and having mortises fitting the tenons, and a carrier secured to the members.

6. In a chain conveyer, a link having a recess between its ends'at each side; a car.- rier attaching member mortised in eachrecess, the sides of said carrier attaching members being substantially flush with the outer- SlClBS of the link, and a. carrier secured to the members.

7. In a chain conveyer, a link having a recess between its ends at each side; tenons projecting from the link in each recess;jacarrier attaching member secured in. each recess; extensions on the opposite sides of each member having mort-ises fitting the tenons and disposed in the recess with the outer sides substantially flush with the sides of the link, and a carrier secured to the members. r

8. In a chain conveyer, a link having a recess between its ends at eachside; a pair of tenons projecting'from the link in each recess and disposed in a horizontal plane; a second pair of tenons projecting from the link in each recess and disposed in a vertical plane; a. carrier attaching member secured to the link in each recess and havingmortises fitting the tenons, one pair of mortises snugly fitting the horizontal faces of the first mentioned tenons and the other pair of mortises snugly fitting the vertical faces of the last mentioned tenons, and a carrier secured to the members.

Intestimony whereof I have signed my name to this specification.

LEWIS LOMANDO.
