CONVEYER-BELT.

Specification of Letters Patent.

Patented May 1@, 1910.

Application filed January 8, 1909. Serial No. M1305.

To all whom it may concern:

Be it known that I, MICHAEL C. GRANEY, a citizen of the United States, residing at Hoosick Falls, in the county of Rensselaer and State of New York, have invented new and useful Improvements in Conveyer- Belts, of which the following is a specification.

This invention relates to endless conveyer belts for grain harvesters and other machinesv and relates more particularly to connecting means for the ends of the belt of that type disclosed in my application Serial No. 433,890.

The invention has for one ofits objects to improve and simplify the construction of devices of this character so as to be comparatively simple and inexpensive to manufacture, and reliable and efficient in use.

Another object of the invention is to provide improved means for attaching the 0011- necting means with the ends of the belt in such a manner as to insure firmness and stability while at same time preventing the belt from tearing.

With these objects in view and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate one'embodiment of the invention, Figure l is a plan view of the meeting ends of a conveyer belt with the improved connecting means. Fig. 2 is a view taken on line 2 2, Fig. 1. Fig. 3 is a perspective view of one of the brackets and attaching clips. Fig. 4 is a similar view of another form of bracket. Fig. 5 is a fragmentary perspective view of one end of the belt showing the manner of arranging the same for the reception of the attaching clips.

Similar reference characters are employed to designate corresponding parts throughout the views.

Referring to the drawings, A and B designate the meeting ends of a canvas, leather or other flexible conveyer belt, which ends are connected together by a lacing device designated generally by C. On the outer face of the conveyer belt are spaced strips or abutments 1 which insure the ready transportation of the material carried by the belt. The belt has its terminal portions 2 and 3 doubled back on itself the terminal portion 2 being doubledunderneath while the portion 3 is turned back over the top of the belt. At

the bend 1 where the belt is doubled backwardly is arranged a transversely-extending rod 5 which insures a proper grip for the clips or attaching devices 6. These attaching devices are constructed with parallel members or jaws 7 which have their inner ends curved outwardly in opposite directions for embracing the portion of the belt surrounding the reinforcing rods 5, and the members or aws 7 are apertured for receiving clamping screws 8. Attached to the clips are lacing brackets or arms 9 of substantially the same construction and arrangement as shown in my prior application hereinbefore mentioned, and these brackets receive lacing cords 10. The transverse portions of the lacing cords are connected by a longitudinally-extending spring 11 or takeup device which insures the proper tension on the belt. One set of brackets are detachably connected with their respective clips so that the ends of the belt can be readily connected or disconnected. For this purpose, the clips on one end of the belt are construct ed as shown in Fig. 8 with a hook 12 for receiving the loop 13 of the lacing bracket 9. The end bars 14 of the loop are provided with notches 15 for permitting the loop to be detached from the clip. In detaching the bracket, the same is turned on the clip in such a position as to bring the notches 15 in line with the mouth 16 of the hook, and when in this position, the bracket can be slid laterally out of the clip.

In order to cover the connecting device C so as to preserve the continuity of the belt, a

7 covering flap 17 is provided which is preferably a continuation of the doubled-back portion 3 of the end A of the belt. The said portion 3 is itself doubled backwardly at a point 18 directly under the strip 1 and the flap 17 is of such length as to extend over the connecting means C and terminate adjacent the strip 1 on the end B of the belt. The three thicknesses of the belt are pierced by staples 19 that are driven into the strip 1 and these staples span a reinforcing rod 20 bearing against the under surface of the belt, as shown in Figs. 2 and 5, whereby the belt is firmly secured to the strip 1.

From the foregoing description, taken in connection with the accompanying draw ings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the. best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.

Having thus described the invention, what I claim is 1. A conveyer belt having terminal portions bent backwardly, rods extending transversely to the belt at the point where the latter is doubled, clips spanning the doubled portions of the belt and shaped to grip the belt around the rods, and lacing means connected with the said clips for uniting the ends of the belt.

2. A conveyer belt, transversely-extending rods around which the terminal portions of the belt are doubled, clips straddling the bled portion of the belt, clips engaging over 1 the doubled portion and clamping the latter to the rod, said doubled portion being itself: bent forwardly to form a covering flap, clips on the opposite end of the belt, and connecting means attached to the clips and arranged to be covered by the said flap.

In testimony whereof I allix my signature in presence of two witnesses.

MICHAEL C. GRANEY.
