ENDLESS WOVEN BELT.

Specification of Letters Patent.

Application led May 27, 1908.

Patented Feb. 16, 1909.

Serial No. 435,320.

To all whom it may concern:

Be it known that 1, 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 certain new and useful Improvements in Endless Woven Belts, 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 of securing the ends of said belting together to form a continuous belt, both faces of which are without a break making the endless belting reversible.

The invention consists in a novel means of connecting the two ends of the woven belting together and uniting the same in such a manner that the connection between the two ends is as strong as any other part of the belting.

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 view of one end of a piece of woven belting showing the longitudinal strands extending beyond the ends of the filling members thereof, a portion of these longitudinal strands being unlaid to show the inner wire portions thereof. Fig. 2 represents a longitudinal section of the same showing the longitudinal strands, beyond the end of the filling members, crossed. Fig. 3 represents a similar longitudinal section ofthe opposite end of said belting showing the longitudinal strands beyond the end of the filling members uncrossed. Fig. 4 represents a plan of a portion of the endless belting showing the two ends brought together and united. Fig. 5 represents a side elevation of the same. Fig. 6 represents a longitudinal section of the same, the cutting plane being on line 6-6 on Fig. 4, and Figs. 7, 8, and 9 represent, respectively, transverse sections of said belting on lines 7 7, 8 8, and 9-9, on Fig. 4.

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

ln the drawing is represented a portion vof the woven belting which is made up of a plurality of strands 1() and 11 which cross each other at 13 and are connected together by means of the cross members 14. These cross members 14 extend transversely of the belting between the

longitudinal strands

10 and 11 and the ends of said cross members 14 at each end of the belting, before being united to form an endless belt, are united by suitable seizing 15 or any other means may be used which will connect the two ends of the cross member 14 together and prevent the lateral separation of the

longitudinal strands

10 and 11. The fillingmembers 14 may be similarly united together at another point by an additional seizing 16 if desired. The

longitudinal strands

10 and 11 extend beyond the united ends of the filling members 14 as indicated in 1. Preferably the extending portions of the strands are of different lengths and a ortion of the textile material 17 is unwounfl) for a limited distance from the end of each strand, as indicated in Fig. 1. 1n lilre'manner the wire portion 18 is similarly unwound from the wire core 19 for a limited distance from the end of said strand and after unwinding the wire portion 18 from the wire core 19 a section of said core 19 is cut away as indicated at 20 in Fig. 1. The opposite end of the wire belting has its corresponding strands 10 extending beyond the united filling members 14 in a similar manner and these extending portions of the strands 10 are similarly treated by having the textile material and wire portion unwound for a limited distance and the ends of the cores 19 cut away. Vilhen both ends of the filling have been thus treated and the ends of the filling members 14 united together by the seizing 15, the

strands

10 and 11 are crossed as indicated at 21 in Fig. 2 while the

strands

10 and 11 at the opposite end of the belting are left uncrossed, as indicated at 22 in Fig. 3. The two ends of the filling are then brought together until the transverse portion 14at of the filling member 14 at one end of the belting and the transverse portion 14b of the filling member 14 at the opposite end of the belting are about the same distance apart as the remaining transverse portions of the filling members 14 are separated from each other. When this has been done one of the longitudinal strands 11, as, for instance, the strand 11a, of the righthand end of the belting is unlaid and the strand 11b of the lefthand end of the belting is inserted in its lace, being interwoven with the filling vmembers 14 for a limited distance. The vtextile material 17 is removed from the end of the longitudinal strand 11a for a limited distance leaving exposed the wire portion 18 from which a section of a core 19 has been removed as previously described.

strands 11a and l1b` are brought together and twisted together as indicated at 23. When the two wire ends 18 have been thus twisted together the unwound textile material 17 is wound about the twisted wire portion 23 as indicated at 24 and also about the untwisted end portions 2.5 which have the textile material wound about them and are then inserted between the

longitudinal strands

10 and 11, as shown in Fig. 4. Each strand 11 is similarly united with a corresponding strand 11 in the opposite end of the belting, the uniting of the different strands being at dierent points in the length of the belting. The strands 10 of the righthand section are similarly united to corres Onding strands lO in the lefthand section o the belting. The removal of the portion of the core 19 of each

longitudinal strand

10 and 11 reduces thev bulk of said strands at the point where the wire ortions 18 are twisted together, thereby o viating an enlargement of the belting at that particular point, the twisting of the two wire ends 18y together leaving the diameter of the united strand practically the same as one of the strands with the wire core therein.

The wrapping of textile material such as marline about the united wire portions prevents the wire from rusting and deteriorating while at the same time it prevents wear of the parts when under considerable strain and creates sufficient friction to prevent the parts from becoming displaced.

When the two ends of the belting are united in the manner herein described the belting becomes endless, both faces being practically free from any rotuberances and as a consequence when tlhe inner face becomes slightly worn the belting may be reversed and what was formerly the outer face of the belting be placed next to the pulleys upon which the belting operates.

Constructed in the manner set forthA the belting is of great tensile strength, the point of connection, as 7`7 being no weaker than any other portion of the belt.` While the capability of reversing the belt is of some advantage a still greater advantage due to this construction is the great flexibility of the belt and the freedom from any rigid clam ing members.

It is believed that from the foregoing the Thetwoy ends of the coreless wire portions 18 of the operation of the invention and its many advantages will be fully understood without further description.

Having thus described my invention, 1 claim:
