'To ALL WHO-M 1T MAY eoNoEnN;

Bc 'it known that I,-RoBnRTJ. JORDAN, of the town and county ot` Elkhart, and State 4of Indiana, have invented a new and useful Improvement in Belt-'Couplings; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the aecompanying drawings, making a part of this specification', in whichi Figur-c1 represents a top view of my improved device for conpling the belting.

Figure 2 a side view of the same.-

Like letters in both iigures'of the drawings indicate like parts.

My'invention has reference to the construction of metallic plates provided'with longitudinal slots and capped and spearhealdrivets, in combination with the halting, whereby, when the ends of the sections of the belting have been lapped together for coupling, and one or two of the said slotted plates transverselyarranged on the upper lappingpart of the belting, and one or two on the under side opposite thereto, which under plates have only round holes, the belting may be fastened by the insertion therein of either the said spear-head rivet being d riven through the leather, or the leather perforated and the said capped rivet placed through, and the heads of the rivets turned across the slots of the upper plate, so that any possibility of the belting breaking loose `from the point of its connection is eieotually prevented; and by the facility with which the plates are attachediand the rivets applied and likewise removed, the belting may be readily shortened or any change made in reference thereto when desired.

The belting is .represented by the letter A, the platos by B, the capped rivet by a, and the spear-head one by The rivets, for the purpose of showing them clearly, are detached from the plates andV shown in detail on the drawings. The plates are to be made of a suitable width, and as thin as possible, so as not to present toc much projection on either side oil-the belting, and thus oil'er an impediment somewhat to the freeland easymovemen't of the same, and yet made suiiiciently thick for the purpose required. The slots of the' top plates 'are represented by the letter c, (see g. 1.) The bottom plates have round holes, which are countersunk to receive the heads of thc rivets ush with the surfaces of the plates. When the plates are properly adjusted for coupling the belting, and if'itis desired to used the capped rivets, holes are punched through the leather and the rivets -then introduced, which, having dat longitudinal heads, are turned transversely over the slots of the top plates, (see tig. l.)

The rivets constructed with spear-heads or points may be more conveniently used than' the capped ones just described, as no -ho'les are requred to be punched, they being driven through. When introduced and having heads like the others, 'they are turned the same as those. This kind of rivet, however, cannot be used to adiiantage where two pulleys are in close proximity to one another, as the spear projections, if on the belting of a lower pulley, are apt to come in contact or interfere with the movement of the belting on an upper one, and vice versa; otherwise it .will be found to be a'very desirable and convenient rivet to use. Where the pulleys are close together, and to avoid any possible chance of the capped rivets giving trouble in the respect above remarked, their heads maybe attened close down over the slots ofthe plates, and the ends of the lbelting, aftervbeing lapped together, pared down to a.V tapering form, (see iig. 2,) and a strip of leather made to fit over the whole, and then tacked to the halting this will give comparatively a smooth surface to the top ofthe same. In order to prevent any diminishment of the friction ofthe bel'ting on the' pulleys, were the bottom' plates allowed to come in contact with the smooth'surfaces of the same, a strip of leather is made to cover the plates,

as shown by the letter d, in like manner as would be that on the top. These rivets may be provided with screwthreads instead of capped or spear heads, and flat screw-nuts applied to the rivets, andsthe` plates made to couple the belting by thismeans.

It is intended that inclined recesses shall be formed on each side of the slots of theplatcs',`it` the same i will admit of it, or the plates in their construction may have inclined pieces on each side, or the pieces properly attached thereto, whichever is deemedpracticable. The incline on one side ofthe slot is diagonally reverse to that on the other side, (see the letter C representing the plate, and the letter e showing the inclines in the two views in detail.) It will thus be observed that with the =heads of the rivets inclined rev'crsely on each side of the shank so as to correspond with the inclines, they can be made to clamp the plates tightly to the belting by turning the heads with a pair of pineers, which, as they are turned, become wedged fast on the inelines, and hence compress the ends of the belting together, and at the same time are not liable to work around and slip out of the slots. This feature of my improvement will enable the belt-ing to be coupled as tightly as may be desired.

The longitudinal slots, as hereinbefore described, and as seen in fig. 1, constructed parallel with the sides of the plate, may be constructed dierently by their being made across the plate parallel with the ends of the same, (see the letter c representing the slot, and the letter a', the rivet at the end of it in the top view of the plate in detaih) which when the helting is extended out over the pulleys, the rivet will be in the position just described, consequently if' the rivet should work around with its sides parallel with those of the slot, half of the head or cap ef the saine will be over the plate. This being the case, the rivets will have no possible cha-nce of slipping out of the slots.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The platos B provided with inclined depressions or pieces e formed on the sides of the slots c and c', and spear-head rivets b, in combination with the belting A, substantially in the manner and for the purpose as herein set forth.
