IMPRVEMENT IN SPLIGING BELTl-NG.

TO .A LLWHOM-IT MAY CONCERN:

Be it known that I, N. E. SMITH, of East Cleveland, in the county of Cuyahoga, and State of Ohic,.h'ave invented certain new and useful Improvementsinl Splicing Belt-s; and I do hereby declare that the folloiving is a full and complete ldescription of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a view of two sections of belting cutter-splicing.

Figure 2 a. view of the sections lwhen spliced.

Like vletters of reference refer to like parts in the viewspresented.

The usual manner of splicing belts is by shingling or shaving down the hair side of o ne end of a piece of belting, and the ilesh side of the other, and then lapping the two pieces uponeach other andcementing them together with any appropriate'material. To give additional strength and security to the splice of the larger class cf belts rivets are employed, thus adding to the'labor of making the belt and increasing the cost of the same., Theobjection to belts thus made is that the thin edges of the lap will break loose and curl up'. This not onlyiweakens the belt, but the folding back of` the loosened ends formsridg'es across the belt, thereby making it rough and uneven. Also belts made by thus splicing thein are not so strong, for the reason of` cutting away too much of the thickness of the leather. The stretching of the outer side of the belt, and consequent crimping ci' the inner side, as it bends in passing around the pulley, tend greatly to strain the lap apart by the opposite and unlike action i exerted upon the splice. More especially is this the case when the beltpasses' around a small pulley, thus bringing the strain more across the grain of the leather, or rather the angle -oi` the splice. r

In order to avoid this diiliculty,and give greater strength and security -to the splice, the following-described way is adopted, viz: d

' ,The ends of the strips of beltng B C, instead of being'shaven down to long tapering Wedge-like ends for the splice, are cut out vertically into a number of tapering tongues, A, fig. 1, thus preserving the thickness of the leather intact. The ends .on being thus prepared are then glued and brought together :and thetongues made to iterlock, as shown in iig. 2. By this it will be evident that there is no weakening of lthe belt by shaving down the ends for the lap, which ordinarily requires about one-half the thickness of the leather; whereas in tonguing the 4 splice in the manner' as described, thel whole thickness of' the leather is retained ;A also in this splice, on bending or warping the `belt around a pulley, there are no thin ends to break loose and roll up across the belt, making it rough and ridgy. In this manner of splicing the strain of the b elt is withrthe grain of the leather, hence-there will be no strain across' the angle of the splice, nor any tendency to break apart, as in the old manner of splicing.

W hat I claim as my invention, and desire to secure by Letters Patent, is-

The herein-described method of splicing belts in the manner substantially as specified. N. E. SMITH.
