CLAMP FOR ROPE BELTING.

Specification of Letters Patent.

Patented Nov. lO, 1908.

Application filed February 24, 1908. Serial No. 417,603.

To all 'whom it may concern:

Be it known that I, JACOB KAST, a citizen of the United States of America, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented cer tain new and useful Improvements in Clamps for Rope Belting, of which the following is a specification.

This invention relates to endless belting and particularly to that class of belting which is woven from a plurality of strands of textile material, and it relates particularly to the means for securing the ends of said belting together to form a continuous belt, the inner face of which is without a break.

It consists in crossing the ends of the longitudinal strands of said belting and laying these ends parallel to one another on either side of the point of crossing upon an inner section of the belting and then clamping these strands eftectually to said inner sections by devices which engage with the outer layer of strands of the inner section of belting, thus leaving a portion of the strands beyond the limit of the fastening devices and interposed between the same and the face of the pulley when in operation.

The invention further consists in certain novel features of construction and arrangement of parts which will be readily understood by reference to the description of the drawings and to the claims hereinafter given.

Of the drawings: Figure 1 represents a plan of a portion of an endless belting connected together by my improved device, one of the plates being shown removed therefrom and the securing staples therefor cut in section, the cutting plane being on line 1-1 on Fig. 2. Fig. 2 represents a vertical section of the same, the cutting plane being on line 2-2 on Fig. 1. Fig. 3 represents a transverse section of the same, the cutting plane being on line 3-3 on Fig. 2, and Fig. 4 represents a transverse section of the same, the cutting plane being on line` 4 4 on Fig. 2.

Similar characters designate like parts throughout the several figures of the drawings.

In the drawings, 10 represents a portion of woven belting made up of a plurality of strands 11 and 12 which cross each other at 13 and are connected together by means of the cross strands 14. At each end of the belting' 10 the cross strands 14 are terminated at 15 while the longitudinal strands 11 and 12 extend for a short distance beyond, as at 16 in Figs. 1 and 2, forming disconnected ends terminating at 17. These disconnected ends 1G cross one another at 18 and rest upon one section of the belting the strands of which are connected together by means of the cross strands 14.

On either side of the point of crossing 1S and resting upon the disconnected strands 1U are the plates 19 provided with the downward turned lips 20 which embrace the disconnected ends 16 and prevent them from spreading outwardly when strain is brought to bear thereon. Each of the plates 19 is provided with a plurality of staples 21 in four rows, said staples being staggered with the staples in one row overlapping the staples in the next adjacent row. rlhe outer ends of the staples 21 are threaded and upon these ends the nuts or other adjusting devices 22 operate. The cross member of each staple 2l is flattened as at 23 and passes beneath a plurality of strands 11 or 12, the plurality of staples in two adjacent rows acting upon all of the strands 11 while similar staples'in the other two rows of each plate operate upon all of the strands 12. By this means each one of the strands 11 and 12 in each section of belting is clamped firmly and effectually against the disconnected ends 1G of the strands of the opposite section and these in turn are clamped against the plate 19.

A greater tension may be brought to bear upon the various parts to more firmly clamp them in position by means of the nuts 22 which may be moved along the threaded ends of the staples 21 for this purpose. It is obvious that from an inspection of the drawings a thickness of fibrous material is interposed between the staples 21 and the face of any pulley on which the belting is adapted to be used. The plates 19 are prevented from slipping longitudinallyof the belt 10 by means of their ends abutting one another and the staples 21 therein being immediately on either side of the point of crossing of the disconnected strands 16.

By such a construction as this a most effectual clamp is made for connecting the ends of such a belting as is herein shown, leaving the inner face or contacting face pertectly even throughout its ent-ire surface while the ends are so iirmly and etectually locked together that there is no opportunity for separation at this point.

In the drawings the belting is shown opened up and Somewhat exaggerated in order to more clearly illustrate the invention.

It is believed that trom the foregoing the operation and advantages ot this invention will be fully understood.

Having thus described .my invent-ion, I claim:

l. rlhe combination of a woven belting; a plate; a plurality of staples therein adapted to engage all the longitudinal strands of one end ot said belting and grip between them and said plate the strands of the opposite end; and adjusting devices'eoperating with said staples.

2. The combination of a woven belting; a plate; a plurality of staples therein staggered in relation to each other; and adjusting devices cooperating with said staples.

The combination of a woven belting; two plates; a plurality ot staples in each plate adapted to engage all the longitudinal strands ot one end ot saidbelting and grip between them and said plate the strands ot' the opposite end; and adjusting devices cooperating with said staples.

4. The combination of a woven belting; two plates, said plates abutting one another; a plurality ot' staples in each plate adapted to engage all the longitudinal strands of one end of said belting and grip between them and said plate the strands of the opposite end; and adjusting devices cooperating with said staples.

The combination of a woven belting; two plates; a plurality7 of staples in each plate, said staples in one plate being adapted to grip the strands in an intermediate section of one end of the belt-ing while those in the other' plate are adapted to grip the strands of an intermediate section ot the other end ot the belting; and adjusting devices coperating with said staples.

G. The combination of a woven belting; two plates each provided with a plurality ot staples in a plurality of rows overlapping each other; and adjusting devices on said staples, the staples of each plate being adapted to pass through the center of an intermediate section of one end of the belting and grip between it and said plate the eXtreme ends ot the strands at the other end of said belting.

7. The combination of a woven belting; the stra-nds at each end of which are crossed and laid iat upon an intermediate section of the other end of the belting; and a connector consisting of means connected with the outer layer ot each of said intermediate sections for effectually locking said strands of the other end thereto.

'8. The combination of a woven belt-ing, the strands at each end of which are crossed and laid flat upon an intermediate section of the other end of the belting; a plate on each side of said crossing of the strands adapted to rest upon said strands; and means secured to said plate for etlectually locking said strands to the intermediate section on which they rest. Y v

9. The combination ot a woven belting, the strands at each end of which are crossed and laid flat upon an intermediate section of the other end of the belting; a plate on each side of said crossing ot the strands adapted to rest upon said strands; and a plurality of staples secured to said plate tor etllectually locking said strands to the intermediate section on which they rest.
