EDWARD H. NOACK. OF STSCKTON. CALIFORNIA. ASSIGNOR TO MONABCH FOUNDRY COMPANY. OF STOCKTON, CALIFORNIA, A CORPORATION.

OONVEYEB CLEAT.

Application filed June 10, 1826. Serial No. 114,885.

This invention relates to improvements in conveyer cleats of that type articularly used on chain drag conveyers or sawdust and refuse in saw mills and like places.

The object of the invention is to produce a sectional cleat for the purpose which can be easily and quickly assembled on the chain and there secured in position. A further object is to produce a cleat which, when so assembled on the chain, is so constructed that the sectional parts may be accurately and rigidly fastened together so as to be in effect a single unitary structure. This will insure long life to the cleat and render its operation 16 properly effective.

A further object of the invention to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views:

Fi 1 is a top 'lan view of a section of the rag chain an ,cleats as they appear in operative assembled position in the drag trough.

Fig. 2 is a side elevation of the sectional parts of a single cleat showing them in position assumed as the are being assembled into the chain, the c ain link being shown in section.

Fig. 3 is a top plan view of the bottom section of the cleat.

Fig. 4 is a longitudinal vertical section throu h a completely assembled cleat.

Re erring now more particularly to the characters of reference on the drawings, the numeral 1 designates the drag chain link into which the sectional cleat is assembled.

The cleat comprises two complementary members consisting of a bottom section 2 and a to section 3. The bottom section 2 is provided with a transverse recess 4 in its under face to receive one side of the link 1. The opposite side of the section 2 is cut away as at 5 in a plane surface to a point just short of the center line of the cleat where it raises slightly to form a shelf 6 at the center of the cleat, from which shelf is a curved portion 7 rising upwardly in a substantially 90 degree are to the top surface of the cleat.

The cut out portion 5 as well as the shelf 6 and the top roper of the cleat section 2 is full surfaced from edge to edge of the cleat section.

In the face of the shelf 6 is a cut-out recess 00 8 and in the face of the surface of the cut away portion 5 adjacent the front face of the cleat is another cut out recess 9.

The cleat section 3 is made as a com lement to the section 2 to make the comp ete cleat and has a cut away portion 10 to fit over the shelf 6; a lug 11 to fit the recess 8; 3. lug 12 to fit the recess 9; and a curved end 13 to fit the curved portion 7. Immediately ad'acent the curved end 13 is a recess 14, a apted, when the sections are assembled, to be parallel with and in the same vertical plane as the recess 4 so that the curved end of the sections 3 may be rotated into engagement with the link 1 and com- 7 plete the cleat tied into the link. Both sides of the section 3 have full surfaces from edge to edge, so that when the sections are assembled the under surface lies flush with the surface of the cut away portion 5 and the

lugs

11 and 12 fit snugly into the

recesses

8 and 9 to definitely and positively fix the proper relative position of the two complementary sections and make a substantially solid and unitary cleat when the parts are $5 riveted together, as will now be explained. In adjacent outer ends of the

sections

2 and 3 are alined

rivet holes

15 and 16 respectively. When the parts are assembled a rivet 17 is set through these holes and secures the parts together as a unit.

After the sections are riveted together the flat contacting surface between the two and the abutting shoulders formed between the upraised shelf 6 and the cut out portion 1') together with the spaced

lugs

11 and 12 fit ting closely into the

recesses

8 and 9 positively prevent either transverse or longitudinal loose movement between the

sections

2 and 3, and hence shifting of parts and consequent wear and inefficient operation is completel avoided.

From t e foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

1. A conveyer cleat comprising two C0111- plementary cleat sections one section having a flat under surface rovided with a transverse groove interme iate its ends and a fiat surfaced cut away portion in its upper side extending from one end to a oint short of the groove, an upraised shel at the inner end of the cut away portion and crossing the plane of the roove and curving in 'an arc to the top surface of the cleat; the other section having a flat surface to lay against the flat surface of the cut away portion of the first section, a cut out portion to seat over the shelf, a curved end {0 engage the curve of the shelf, the inner end of said second section being provided with a transverse groove arranged to lie parallel with and in the same vertical plane as the transverse groove in the first section when the two are assembledto ether; and means to fasten the sections rigi lyjogether.

2. A conve er cleat comprising two complementary c eat sections, one having a fiat under surface rovided with a transverse groove interme iate its ends and having a at surfaced cut away portion in its upper side terminating short of the transverse center .line of the cleat section, an upraised shelf at the inner end of the cut away portion and crossing the center line of the cleat section and curving in an arc to the top surface of the cleat; the cut away portion and the shelf each having a recess in its surface; the other section having a flat surface to lay against the fiat surface of the cut away portion of the first section, a cut out portion to fit over said shelf, a curved end to engage the curve of the shelf, lugs to fit into said recesses, the inner end of such second section being provided with a transverse groove arranged to lie parallel with and in the same vertical plane as the groove in the first section when the two are assembled together; and means to fasten the two sections rigidly to ether.

11 testimony. whereof I affix my signature.
