T 0 all whom it may concern 4,

Be it known thatwe, FRANK M. Ronnms and Josnrn S. HARTL Y, citizens of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented certain new and useful Improvements in Conveyor Cleats, of which the following is a specification.

This invention relates to cleats for use with conveyors for handling slabs, sawdust. shavings or other material.

An object of the invention is to provide a cleat of simple and rugged construction which maybe easily and securely attached to a conveyor chain. A. further object is to provide a cleat which may be attached to and detached from a chain without the use of special toolsor of bolts or rivets. A further object is to provide a cleat which may be firmly attached to chains having links of different size or to. a chain having links which have become worn in service. More specifically an object of the invention is to provide a cleat which is attached to a chain by --means of a removable wedge which is locked in position by means of malleable projections.

Some embodiments of our invention are disclosed in the accompanying drawings, in

which Fig. 1 isan end elevation of a cleat 011 a conveyor chain; r

Fig. 2 is a front elevation of the same; Fig. 3 is a plan view;

Fig. l is a horizontal section of the butt end of the cleat, and taken on line i-t of Fig. 2;

Fig. 5 is a fragmentary end elevation illustrating modifications in the construction disclosed in Figs. 1-4; inclusive;

Figs. 6 and 7, are respectively a fragmentary end elevation and a plan. of another embodiment of the invention;

Figs. 8 and 9 are, respectively a. fragn1entary end elevation anda plan of another embodiment v Figs. 10 and Ham respectively, a front elevation and a plan of another'embodiment;

7 Figs. 12 and 13 are respectively, a front elevation and a plan of a further embodiment, and

In the drawings, thelinks of the conveyer chain to which the various forms of cleats are attached are designated by the character L. In the embodiment illustrated in Figs. 1 to 4 inclusive, the butt end of the main section of the cleat 1 is provided on its lower face with a groove 2 for receiving one side of a link L. The upper face of the main section 1 has formed therein a cylindricalsurface subtending an arc of approximately 90 which provides a link receiving seat 3 for the reception of the opposite side of the link L. Adjacent the seat 3 the main section is provided with an approximately vertical wall 4:, a second wall 5 being spaced therefrom and located near the end of the cleat. .The walls 4 and 5 define a recess or slot across the end of the cleat, the bottom surface of the recess being formed by the surface 6 which connects the walls 4 and 5. A clamping member 7 in the recess has a seat 8 which cooperates with the seat 3 of 'the mainsection to form a link groove. The member 7 is locked in position by means of malleable lugs 9 formed thereon which may be bent over to lie in recesses 10" formed in the adjacent portion of the main section 1.

In the embodiment of our invention illustrated in Figs. 1% inclusive, the walls 4, 5 are undercut to form a dovetail recess and the wall 5 is inclined to the axis of the link recesses, thus providing a tapered recess or slot. The member 7 has a corresponding dovetail wedge shape conforming to the shape of the recess. faces of the removable member and the cleat may be smooth as shown in Fig. 2, or if desired these surfaces may be corrugated as shown in Fig. 5. Fig. 5 also illustrates a further modification in that the member 7 does not encircle substantially one half of the link L but terminates substantially at the upper surface of the main section of the cleat 1.

Ihe cleat shown in Figs. '6 and 7 is similar in construction to that above described, but the positions of the malleable lugs and recesses have been reversed. In this form the lugs 9 are located on the end of the main section 1' and the cooperating recesses are formed in the adjacent surface of the member 7 As herein shown the cleat I has been applied to a link which has a span between the opposite sides of the link which The contacting suris greater than the distance between the recess 2 and the seat 3. Due to the taper of the walls 4-, 5, the wedge member 7 holds the cleat firmly to the link L even though the link is not perfectly seated on the cleat. As will be obvious this construction also permits the cleat to be firmly attached to links having side portions of a radius slightly greater than that of the link receiving seats.

In the form illustrated in Figs. 8 and 9, the walls 4:, 5 are not tapered, but the lower face of the recess has formed thereon a tapered dovetail 6? which isengag'ed by a correspondingly shaped recess in the lower face of the member 7 As with the forms previously described this cleat may be firmly attached to links of somewhat different size in view of the'taper of the cooperating parts on the member and the main section of the cleat. Y

Figs. 10 and 11 illustrate a universal cleat 12, that is one which extends to both sides of the conveyer chain. A chain receiving recess 13 and a link seat 14 are formed respectively in the lower and upper surfaces of the cleat. Adjacent the seat 145, the main section of the cleat is provided with a transverse recess of tapered dovetail construction for the reception of a locking wedge 15 upon which are formed malleable lugs 16 which may be engaged in recesses 17 formed in the cleat. Obviously the height and thickness of the main section of the cleat are so proportioned that the cleat may be slipped into a chain link andothen rotated through 90 position for attachment. It is alsooobvious that in place of using a form of wedge mcmber 12 similar to that illustrated in Figs. 1-4L inclusive, attaching means constructed as shown 'in Figs. 5-9 inclusivemight be used. 1

A further form of universal cleat embodying our invention is illustrated in Figs.

'1214 inclusive, in which the main section of cleat is designated by the numeral 18.

' On its rear facethe main section 18 is provided with an extension 19 which terminates in a vertical surface passing substantially through the center'line of the cleat. The

upper and lower portions of the extension 19 are provided with link receiving seats 20 and 21, respectively. Upon the opposite side of the center line of the cleat, the main section -18 is provided on its rear face with a tapered dovetail projection 22 having a notch 28 formed therein near its outer end.

The cleat is held to a chain link L by means of a member 2a which has formed in its lower surface a tapered dovetail recess by means of which it may be slid into position along the back of the main section 18. The member 24; is provided with upper and lower link seats 25 and 26 which cooperate respectivelywith the seats 20 and 21 to form link 'rece'sws. The outer end of the memberQ thereby as many changes may be made in the various parts, their relative location, size andproportion.
