JACKSON H. CLARK, OF SUNBURST, NORTH CAROLINA.

CLEAT CHAIN CONVEYERS.

Specification of Letters Patent. Patented Apr. 9, 1918 Application filed August 18, 1917. Serial No. 186,953. v

To all whom it may concern:

Be it known that I, JACKSON H. CLARK, a citizen of the United States, residing at Sunburst, in the county of Haywood and State of North Carolina, have invented new and the object of the invention being to provide a. cleat which is light,strong and durable, simple of construction and comparatively inexpensive of production, and which is composed of sections adapted to be easily assembled and firmly secured to a chain link and to present a broad abutment surface for engagement with the slab or other object.

"With this and other objects in view, the invention consists of the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawing, in which Figure 1 is a rear perspective viewv of a cleat embodying my invention as applied to a link of a conveyer chain.

Fig. 2 is a front elevation of the same.

Fig. 3 is a vertical longitudinal section through the applied cleat.

Figs. 4 and 5 are vertical transverse sec- 7 1 tions.

Fig. 6 is a view showing the sections of the cleat disassembled and disposed to expose the construction thereof.

In the practical embodiment of my inven- V pending to a degree equal to the thickness tion I provide a cleat comprising a pair of outer cleat sections 1 and 2 and an intermediate or central cleat section 3. These cleat sections are united in the manner hereinafter described to en age one of the links 4 of a conveyer chain, the cleat being extended through the link and in engagement.

therewith at its center, and projecting to equal degrees beyond opposite sides of the link. For convenience of description the outer cleat section 1 may be termed the top cleat section, and the outer cleat section 2 the bottom cleat section.

The cleat sections are preferably of: the

form shown, each comprising a metallic plate having a straight longitudinal front edge, and having its rear edge inclined on diverging lines from the center of the cleat toward the ends thereof, the cleat thus being made of maximum width at the center, but this form of cleat is not absolutely essential and may be departed from if desired. In practice, the cleats may be arranged any desired distance apart along the conveyer chain, and each cleat engages a vertically disposed link of the chain, as shown.

The top and bottom cleat sections 1 and 2 are alike in construction, and hence a description of one will suflice for both. As shown, the cleat section 1' is provided in its outer face with a transversecentral groove 5 which receives and engages one of the sides of the linkl, while the inner or reverse face of said cleat section is formed with'a'rib or boss 6, Which thickens and increases the depth of the cleat section in the vertical plane of the groove and plane of engagement of the cleat with the chain link, to increase the strength and durability of the cleat at the center, to adapt it to effectually withstand the pressures and strains falling thereon. The inner face of the cleat section 1 is further provided with lugs 7 arranged adjacent to and on opposite sides of the boss 6, and lugs 8 arranged adj acent t0 the ends of said cleat section, the said cleat section being formed with openings 9 and 10 respectively passing through the inner and outer sets of lugs. The lugs 7 and 8 correspond in depth or other object which is to be transported.

cleat sectionstalining for the passage of suit- This intermediate cleat section is provided upon its upper face with a central boss 12, inner. lugs: 13' andouter lugs.-1{4,.a id is provided'along its straight abutment edge with an upwardly extending abutment flange 15, said cleat sectioni'beingiprovidedwithopene ings 16 and 17 extending respectively through the sets of lugs 13 and l li The; in

termediate cleat section differs from the top antl 'lsOtiZOHItClGEtiFSGGblOIIS in that it; is -devoicl of the groove 5, its lower, facebeingfiator plane-surfaced throughout. WVheii the intermediate section, is fitted: in. position. between I the top,..an d, bottom; sections 1. and. 2,1118. boss 12 and lugsl -and, 1:45 thereof. lie in contact #w-ithQthe boss v6 and. lugs .7, and 8 of. the upper cleat section 1, while the flatlowenv face of saidicleattsection, 3 lies in contact. with the boss andlugs o f 2 the, lower. cleat. section2,.the openings in; the abutting faces ofthe several able fastenings, suchas countersunk rivets 118301 connecting bolts, whereby the cleat sections are firmly and. securely bound together and held: improperly assembled, relation against any possibility of displacement or disconnection; When the cleat sections are thus combined to. form. the-.eomplete cleat, the fia-ngesxlfi, oithe ntermediate cleat section are disposed. in: al nement. with and abut against the downwardly and. upwardly V extendin'g fiangesat the topand bottom cleat sections, thus forming atthe front of the cleat a straight abutment surface, of the full depth of. the cleat-,to. engage the. loglor other object. By the constructionof thecleat sections in; the manner described, a/form, of

cleat is produced I which, while exceedingly strong and'durabl is light in weiglitand much less expensive thanv a. construction, employing solid. cleat blocks on sections.

In. applying the, cleat. to the. chain' link the bottom cleat. section2. is firstinsertedlin position.- through; the link, after which the top cleat section is arranged in pl,21(2e 2 11 1l then. the intermediate cleat. section is inserted fromione endbetweenthe top fillClQljOll' tom cleat. sections, thus spreading the same apart. and binding them. into engagement with the, Side barsof'the links which are receivediintoithe grooves 5, the rivets or bolts sections.-v may. be, with. the, exeeptionof the groovesihflat on of: any other desired formation.

From the foregoing description, taken in connection with the drawing, the construction; and mode of. application and use of my improved sectional cleat-will be readily understood, and it will be seen that a cleat is provided which; is siinple of construction,

capable of being easily and conveniently applied for use and as easily removed for 1 repairs, the substitution of a new cleat-or cleat sectioiuori for other purposes. It will also be seentliatt-lie construction described is of material advantage fromthe standpoint of. economy and lightness in wei'gl'it, withoutsacrifice oif'strengtli andrdurability.
