\ To all whom t may concern.'

Be it known that I, VENZEL IVEICHSEL- noRrER,-`a citizen of the United States of America, residing at Potlatch, in the county 4 of Latah and State of Idaho, have invented new and useful Improvements in Conveyer- Cleats, of which the following is a specification:

The invention relates to an improvement in cleats for conveyer chains designed primarily for use with saw mill slab conveyers.

The main object of the present invention is the provision of a cleat adapted for removable connection with the appropriate length of the conveyer chain, the construc tion permitting the connection of the cleat with the link in a substantial and effective manner through the use of a single bolt.

The invention will be described in the following specification, reference being had particularly to the accompanying drawings, in which- Figure 1 is a perspective View of the cleat showing the same applied to the conveyer chain. Fig. 2 is a perspective view of the clamping section. Fig. 3 is a perspective view of the main section. Fig. 4 is a plan of the improved cleat. Fig. 5 is a side elevation of the same. Fig. 6 is a rear elevation of the same. Fig. 7 is a section on line 4 4 of Fig. 5. Fig. 8 is a section on line 5-5 of Fig. 4.

Referring particularly to the accompanying drawings, wherein is shown the preferred form of the present invention, my improved cleat comprises what I term a base section 1 and a clamping section 2, each preferably comprising an integral casting. The base member'l includes a bearing plate 3 of substantial width and length from one edge of which is upwardly projected what will be hereinafter termed the engaging plate 4. The bearing plate 3 gradually decreases in thickness from the engaging plate 4 toward the free edge of the bearing plate, the upper surface only of the bearing plate being inclined. The lower surface of said plate is at right angles to the respective surfaces of the engaging plate and is preferably formed with an elongated recess 5 whereby to reduce the surface ofv the bearing plate with the slab table to minimize friction incident to the travel of the cleat along the table. At the relatively rear or chain engaging end the engaging plate is reduced in height to provide a shoulder portion 6, which, as

shown in Fig. 6, is on a plane slightly above the upper surface of the bearing plate 3.

. The forward edge of the reduced portion is formed throughout its height to provide a curved or link engaging surface 7, while the `reduced portion of the engaging plate in rear of the link engaging surface 7 is laterally enlarged, as at 8. In advance of the reduced portion the engaging plate 4 is recessed or reduced in thickness at 9, said reduced port-ion being so formed as to leave an inclined outwardly projecting iange 10 coincident with the lower edge of the engaging plate and a relatively thickened portion 11 immediately in advance of the link engaging edge 7, the cutaway portion 9 otherwise extending throughout the height and length of the engaging plate. From the relatively rear edge the bearing plate 3 is of uniform width throughout its length, as at 12, the free edge of the bearing plate being extended in advance of the portion of uniform width at an inward incline relative to the opposing edge of said plate, as at 13.

To the free edge of the plate 3 throughout the portion of uniform width there is provided a holding plate 14, which, at the forward portion, is coincident in height with the height of the engaging plate and at the rear portion is reduced to provide a shoulder 15 corresponding to and arranged in transverse alinement with the shoulder 6 of the engaging plate. The forward edge of the shoulder 15 is formed with a link engaging surface 16 curved to correspond to the surface 7 of the receiving plate. The reduced portions 6 and l5 of the receiving and holding plates are of less width than the plates immediately in advance of said portions whereby to provide a shoulder 17 at the juncture of the reduced portions with the plates proper, and also to in efl'ect widen the bearing plate throughout its length in rear of said shoulders. Centrally of the rear edge the bearing plate is formed with a recess 18 opening through said rear edge and of rectangular formation, the forward wall of the recess being inclined, as shown.

The clamping section comprises a main plate 19, which, at its relatively rear end, is formed with an upward extension or block 20. The main plate of the clamping section is at its rear portion immediately adjacent the block formed with a rounded depression 21, and the forward or proximate face of the block is formed wit-h a curved surface 22 arranged to coperate with the

surfaces

7 and 16 and preferably forming a continuation with the recess 21, as clearly shown in Fig. 8. That portion of the main plate including the recess 21 and also the block is coextensive in width with the width between the reduced portions 6 and 15 of the engaging and holding plates, while that portion of the plate in advance of the recess is reduced to fit between the engaging and holding plates in advance of the shoulders 17. By this construction the clamping section lits snugly between the receiving and holding plates with the shoulders formed by the relatively different widths of the main plate bearing aga-inst the shoulders formed by reducing the width of the portions 6 and 15 of the receiving and holding plates. As a further means for connecting the parts I provide the undersurface ofthe main plate of the clamping section with a block 23 designed to snugly fit the recess 18, the forward wall of the block being inclined to snugly engage the inclined wall of the recess. v

The reduced portion of the main plate of the clamping section is centrally formed with an opening 24 adapted to register with an opening 25 formed in the bearing plate 3 to receive a bolt 26 on which is threaded the usual nut 27 to secure. the clamping section in place. The opening 25 is preferably countersunk so that the head of the bolt will lie flush with the undersurface of thevbearing plate to avoid obstruction. n p

The use of the improved cleat will be readily understood from the above description taken in connection with the drawings, it being noted that upon the removal of the bolt 26, the clamping section may be readily separated from the main section and thereby permit the convenient coupling of the sections to the desired bar of the link. The

bar receiving portions

7 and 16 of the main section, recess 21, and curved portion 22 of the clamping section are, of course, so relatively arranged as to accurately engage the link bar and to present, when the clamping section is secured in place, a rounded aperture extending transverse the cleat and opening at the upper portion, the opening being, of course, materially less than the diameter of the aperture. i

When it is desired to disconnect the cleat it may be readily separated from the chain by the removal of a single bolt, and in the event either portion of the improved cleat should become worn it may be readily replaced without necessitating the disuse of both parts.

Having thus described the invention what is claimed as new, is:-

1. A conveyer cleat including a main section formed with an engaging plate, and a clamping section designed to be removably secured to the main section, said clamping section and engaging plate being formed with oppositely curved surfaces to engage a link of the conveyer chain, the curved surfaces of the engaging plate being arranged in spaced relation transverse of the plate and the curved surface of the clamping section being of a lengt-l1 exceeding the '.distance between the curved surface of the engaging plate.

2. A conveyer cleat comprising a main section including a bearing plate,'an engaging plate projecting upwardly from one edge of the bearing plate, 'a holding plate Iprojecting' upwardly from the opposing edge of the bearing plate, said engaging and holding plates being formed with curved portions, and a clamping section designed to rbe removably secured to the bearing plate,

said clamping section having a block formed on its forward edge with a surface curved in opposition to the surfaces of the bearing and holding plates, whereby to form a curved aperture extending transverse the cleat.

3. A conveyer cleat comprising a main section including a bearing plate, an engaging plate projecting upwardly from one edge of the bearing plate, a holding plate projecting upwardly from the opposing edge of the'b-earing plate, said engaging and holding plates being formed with curved portions, and a clamping section designed tov be removably secured to the bearing plate, said clamping section having a block formed on its forward edge with a surface curved in opposition to tlie'surfaces of the bearing and holding plates, said blockbridging the space betweenthe engaging and holding plates, whereby to form a link gripping aperture transverse the cleat.

In testimony whereof I afliX my signature in presence of two witnesses.
