HAY-CARRIER.

Specification of Letters Patent.A

To all whom t may concern:

Bezit known that we, HOWARD J. FERRIs and HENRY L. FnRRIs, citizens of the United States, residing at Harvard, in thecounty of McHenry and State of Illinois, have invented a new and useful Improvement in Hay- Carriers, of which the following isa speciication.

Our invention relates to certain new and useful improvements in hay-carriers, and is fully described and explained in the specification and shown in the accompanying drawings, infwhich:

Figure l is a side elevation of my haycarrier; Fig. 2 is an end view; Fig. 3 is a section on the line 3 of F ig. 2, and Fig. 4 is a section on the line 4 of Fig. 3.

The present invention is particularly applicable to sling carriers of that type in which the rope is gripped as distinguished from carriers of the fork type in which `the fork pulley is directly gripped by holding means on the carrier frame. IVe have shown our present invention as embodied in a sling carrier of the general type shown in Letters Patent No. 1,207,285, issued December 5, 1916, to Hunt, Helm, Ferrisdf. Company as the assignee of Henry L. Ferris. The invention, however, is applicable to other forms of sling carriers, that is to say, those provided? with sling pulleys running in a bight and where the load is held in elevated position Iby clamping mechanism engaging the rope. Since the present structure is very similar in vits general features to the structure of said patent, we have neither illustrated all the details of its construction nor shall we describe the same with unnecessary particularity.

Referring to the drawings, 5 is the carriage running upon a track 6 and having swiveled to it a frame-work 7 carrying the operative parts of the mechanism. 8 is a hook movable with the trip member and to it is attached one end of a chain 9 in the bight of which are hung the sling pulleys l0, the chain running up and over the pulley 11 carried in a housing 12 pivoted at its upper end to the swiveled frame and thereby capable of being swung out laterally as the bight broadens when picking up a load. 13 is a locking member, it being of bifurcated form straddling the pulley 12 and one of its furcations is provided with a segmental gear 14 meshing with a segmental gear 15 connected by a link l16 to the trip member 17 which is of ordinary form and Operates in the usual mannerin coperation with a trip block 18. 19 is the releasing member which, when raised, operates the usual dog so as to free'l the trip member and let it fall.

The operation of the present'device will be readily understood by those skilled in the art, particularly with reference to the patent above identified, it being understood that when the carrier is in position where the trip member` engages the trip block, the locking mechanism is released and the sling pulleys can be drawn down to receivev their load in the usual manner, the carrier being held against longitudinal movement on the track by the trip block. When the load is elevated the releasing member 19 is raised by engagement with the sling pulleys and the trip mem-ber falls, not only by its own weight but with the added power given by reason of the fact that half of the loadis hung upon it. As it descends it rocksl the segmental gears 14 and 15 and throws the locking mechanism into operation. The rise of the load thus frees the carrier from the trip block and at the same time locks the load so that the power upon the rope will draw the carrier along the track to its destination.

The important point about the present arrangement is that We have providedfmeans whereby abrasion of the cable and Very annoying incidents thereof are entirely-eliminated. The structure of the patent referred to was designed to reduce abrasion to the greatest possible extent, yet in practice it was found not to be wholly eliminated. It is necessary in hay-carriers to use a large and expensive rope, or else a steel cable of relatively expensive character, and the constant renewal of rope or cable is both inconvenient and expensive.

In accordance with our invention We have employed, as illustrated, a short length of chain at that end of the rope or cable adjacent to the carrier. It would be impossible to employ chain as a substitute for the entire length of rope or cable, on account of the weight and expense, 'but we have discovered that it is entirely possible to use a short length of chain at that point where the clamping mechanism most frequently works. To this end we attach to the end of the rope proper, indicated at 20, a hollow tubular'tting l2l terminating in an eye 22, the tting 2 1 being'firmly attached to the end of the rope and being of such size that it will run over the pulley and through the clamping mechanism when thesame is released. The pulley is also centrally grooved so that the Vchain will t nicely therein without twistl is entirely satisfactory and takes a iirm and instant grip upon the chain without the possibility of damaging the same.

What we claim as new and desire to secure by Letters Patent is 1'. In combination, a track, a carriage movable thereon, a trip. block on the track, a trip member cooperating with the block, a pair of sling pulleys, clamping mechanism and a composite iieXible member composed partly of rope and partly of chain, the chain portion only of said composite member passing through the clamping means, and such chain portion being so positioned as to be gripped thereby by frictional contact with the links when the sling pulleys are elevated.

2. In combination a track, 'a trip block thereon, a traveling carriage, a trip member cooperating with the trip block, clamping mechanism operated by the trip member, trip-releasing means, a pair of sling pulleys adapted to operate the same when raised, a

elevated to release the trip member, and they flexible member receiving partial support from parts connected with the clamping: mechanism, whereby the weight of the load carried by the sling pulleys is operated to grip the chain. j

4. In combination, a track, a carriage movable thereon, a sheave carried by the car'- riage, clamping mechanism and means for releasing the same, sling pulleys, a composite member formed into a bight supporting the slig pulleys and passing over the sheave and through the clamping mechanism, said member being formed partly of rope and partly or' chain, the chain portion being so positioned as to lie within the clamping member when the bight is shortened to elevate the sling pulleys.

In testimony whereof, we have hereunto set our hands this 18th day of April7 1917.
