The carriers are rigidly secured to the wire rope or cable by means of gripping sleeves cold flowed upon the cable and having spaced external grooves for accommodating cooperating. internally projecting flanges of split bushings adapted to be secured within apertured depending portions of the carriers by means of exter-v nally threaded bushings. The carriers are spaced and arranged so that the conveyer is f driven through direct engagement of the driven sprockets with the depending portions of the carriers, the wire rope or cable serving to interconnect the carriers. In order to insure flexibility and the required tautness in the conveyer cable at all times, the supporting structure and driving gears of 'one of the sprockets are mounted upon a wheeled platform connected to a weighted rope or cableY in such manner that the sprockets are yieldably urged away from each other under sulficient pull to insure the required tautness in the conveyer cable.

Referring now to the drawings wherein like reference numerals designate corresponding parts throughout the several views, it will be observed thatan endless conveyer em-f bodying the features of the present invention is indicated generally by the reference numeral 10, and comprises a plurality of wheeled carriers or trucks 11, 11 which are interconnected by means of an endless wire g5 rope or cable 12 arranged to travel around notched discs or sprocket wheels 13 and 14e mounted upon spaced vertical shafts 15 and 16, respectively. The sprocket wheels are provided with peripheral V-shaped grooves- 18 for receiving the cable 12 as more clearly shown in Fig. 5. Y
The carriers 11 may be of any suitable construction depending upon the particular material or articles to be transported thereby. The conveyer illustrated in the drawings is intended for use inconnection with a wire drawing mill for transporting spools or reels of wire -20 to or from the various wire' draw- -ing apparatuses, and for this reason the carriers 11 are provided with a reel supporting platform 22 of arcuate or concave construction to accommodate the circular heads of the reel 20. The platform 22 is formed with upwardly extending end flanges 23, 23 which engage the heads of the reel and thereby prevent longitudinal displacement thereof.
Each carrier is provided with two or more pairs of flanged wheels 25, 25 adapted to ride upon tracks or spaced parallel rails 26, 26 extending between the sprocket wheels. As the carriers travel around the sprocket wheels the flanges of the wheels 25 engage and ride upon the upper faces of the sprockets. It will be understood that the rails 26 are so positioned with respect to the sprockets 13 and 14 that the carriers are maintained in the same horizontal plane at all times.
The carrier platform 22 is formed with a depending boss or hub portion 28 by means of which the carrier is attached to the conveyer cable in the manner hereinafter described. The carriers are so spaced upon the cable that the hub portions 28 thereof engage correspondingly spaced notches 30, 30 of the driving discs or sprocket wheels, whereby the conveyer is driven through direct engagement of the sprocket wheels with the carriers 11.
In accordance with a feature of the present invention, a simple and improved method is provided for securely clamping the carriers 11 to the conveyer cable. Metallic gripping sleeves 32, 32, preferably composed of soft steel, are inserted around the conveyer cable 12 at spaced positions therealong corresponding to the ultimate positions of the carriers. The gripping sleeves are then swaged, hammered or otherwise subjected to external pressure to cause a cold flowing of the metal thereof into the convolutions of the Wire cable, as shown in Fig. 6, thus insuring a rigid bond between the cable and the gripping sleeves. It has been found that a steel gripping sleeve attached to a. wire cable in this manner has a minimum working load of 75% of the breaking strain of the cable.Y
The gripping sleeve 32 is formed with spaced external annular grooves 33-33. After the gripping sleeves have been rigidly secured to the cable in the manner above described, the cable and the gripping sleeves may be severed intermediate the annular grooves 33 of each gripping sleeve, as indi- A cated by the dotted line 34 (F ig. 8), thus providing a plurality of cable sections of a predetermined length, each section having one-half portion of a gripping sleeve attached at each end thereof. Any number of these sections may be interconnected and assembled with a corresponding number of carriers 11 to form an endless conveyer of any desired length. rlhis is accomplished by placing the cable sections in end to end relation, as shown in Fig. 6, and then placing a- Ysplit bushing 35 around the adjoining ends, the split bushing being formed with spaced internally projecting annular flanges 36-36 adapted toengage the annular grooves 33 of t-he split gripping sleeve 32. The split bushing 35 is then inserted in a circular aperture 38 provided in the hub portion 28 of a carrier 11, the aperture having a reduced portion 39 to lit the gripping sleeve, thus providing a shoulder 40 against which the split bushing 35 is rigidly clamped by means of an externally threaded collar 42 adapted to engage internal threads 43 formed in the hub portionof the carrier. AThe locking collar 42 is provided with a plurality of spaced apertures 44, 44 for accommodating a suit.- able tool for facilitating the threading of the collar into the hub portion of the carrier.
The above described method of assembling the parts of the conveyer provides a simple and rigid construction and permits a quick replacement of the parts whenever necessary without replacing the entire conveyer or con veyer cable.
The sprocket wheels 13 and 14 are driven by individual driving units 45 and 46, respectively, each driving unit comprising suitable reducing gears 47 and 48 through which the sprocket shaft is driven from a shaft 49 Vwhich, in turn, is driven by an electric motor 50 through suitable reducing gears mounted in a housing 51. The sprocket wheel 13 and its driving unit 45 are mounted upon a stationary supporting platform 52, while the sprocket wheel 14 and its driving unit 46 are carried upon a wheeled platform 53. The platform 53 is arranged to ride on spaced horizontal rails 54, whereby the sprocket wheel 14 is movable toward and away from the sprocket wheel 13 so as to vary the tension in the conveyer cable 12.
A flexible rope or cable 55 is looped around and secured to a ball bearing collar 56 which encircles the sprocket shaft 16 near the upper end thereof, as best shown in Fig. 5. The ends of the cable 55 are attached to spaced reduced drum portions 57-57 of an idler roller or pulley 58 mounted in a stationary bracket 59. A flexible rope or cable 60 is attached at one end to a central enlarged drum portion 61 of the pulley 58, and is fastened at its opposite end to a weight 62. It will be understood from the construction just described that the wheeled platform 53 and thereby the sprocket wheel 14 is yieldably urged awa-y from the sprocket wheel 13 by the weight 62, whereby the conveyer cable 12 is maintained under a substantially constant predetermined tension at all times. The ball bearing collar 56 serves to counteract any downward thrust and reduces the wear' on the driving shaft bearings.
In the present embodiment of the invention, the sprocket wheels 13 and 14 and their driving units are preferably mounted in a suitable pit or recess in the floor so that the carrier platforms 22 are flush With the floor surface. This arrangement facilitates the loading of the reels upon the carriers.
If desired, a separate and independently Operated conveyer of the same construction as the conveyer l() may be arranged adjacent to and preferably Within the confines of the conveyer 10 so that in the event that it is necessary to discontinue the operation of the conveyer 10 for the purpose of making repairs or replacements therein, the reels may be readily and quickly transferred from the conveyer l0 to the conveyer 65 and the transportation of the reels may thus be continued Without interrupting the activity of other cooperating apparatus.
It will be understood that the embodiment of the invention herein illustrated and described represents merely one useful form of the invention which is capable of modification and numerous other applications Within the scope of the appended claims.
