Application filed April 1'7, 1905. Serial No; 255,907-

To all whom, it may concern:

Be it known that I, WILLIAM LOUDEN, a

citizen of the United States, residin at Fairowing is a specification.

This invention relates to carriers adapted to run on a wire cable or a similar track; and it consists of an improvement in the stop device therefor whereby it may be securely connected to the cable and at the same time be adapted to engage and operate thelock mechanism of the carrier, as will be described in this specification and more particularl pointed out in the claims.

In the accompanying drawings, which form a part of this specification, Figure 1 is a side view of a carrier embodying my invention, the frame of the carrier on the front side being removed to show the interior parts. Fig. 2 is a side view of the stop device, the front sides thereof being removed to show the interior parts and the wire cable being shown by dotted lines. Fig. 3 is a horizontal section on the line 3 3 of Fig. 1, the cable being shown by dotted lines. Fig. 4 is an enlarged transverse verticalsection on the line 4 4 of Fig. 1. Fig. 5 is a horizontal section through the locking parts on line 5 5 in Fig. 1, said parts being shown in full.

Similar letters represent similar parts throughout the several figures.

Referrin to the drawings, A represents one side 0 the carrier-frame, in which the track-wheels B B and a rope-wheel or sheave C are mounted in the usual manner. A rope D is secured to the carrier-frame and is passed over the sheave C in the usual manner, an elevating-pulley E being preferably hung in the loop of the rope D.

F and G represent the two parts of a clamp which is applied to the wire cable H by means of boltsI I. In order to make this clamp adhere firmly to the cable H, I form a projection J in the groove of the part G where it fits on the cable H and a corresponding recess K in the groove of the part F. By this means when the parts F and G are firmly clamped upon the cable H it will be bent or kinked between them, so that the clamp cannot readily slip upon the cable.

L and M represent the main parts of the stop device. These parts are made in two corresponding halves, preferably a little longer than the carrier-frame and adapted to hang substantially below the cable H partially embrace it between them. At the rear ends they are fitted with corresponding curved parts N, which are adapted to en-- circle the cable H and to be held in engagement therewith, a bolt 0 preferably being used to clamp these ends together.

The pieces F and G are provided with ex.- tensions at the ends adjoining the parts L and M, and these extensions are fitted with flanges P, which when fitted together make an annular lip. The ends of the parts L and M adjoining the extensions of the clamppieces F and G are fitted with semicircular grooves Q, which are adapted to fit loosely over the flanges P and to swivel freely thereon. These ends of the pieces L and M are held together and in en agement with the flanges on the parts F and G by means of the bolt R.

The pieces L and M are each provided with a downwardly-projecting spur or lug S, which coincide with each other so as to form a single lug or downwardly-projecting prong. The carrier is provided with a dog T, pivoted in the carrier-frame at U and having two upwardly-projecting spurs or prongs V and W on its opposite ends, which are adapted to coact with the lug S. The free end of the do T is supported by resting on the upper en of a pivoted grappling-hook X. When the pulley E is brought into contact with the hook, it is turned on its pivot, so that the free end of the dog T will drop so the spur V will pass below the lug S, when the carrier will be free to run along the cable H.

The carrier being returned to the stop, the spur W will come in contact with the lug S, which will cause the free end of the dog to rise, and the pulley E being lowered the hook X will turn on its pivot, so as to support the dog in position as shown in Fi 1, and by this means the carrier will be helrIstationary on the cable.

By referring to Fig. 5 it will be seen that the front spur V of the dog T is rounded in cross-section, while the rear spur is broadened and made concave. To accommodate a dog of this construction, the rear faces of the spurs S are rounded to approximately and to I correspond with the concaved face of the spur W, while their front faces are concavedor hollowed out to fit the rounded sides of the The parts L and M are preferably made concave or recessed on their inner sides, and small spurs Y are formed on one of them to catch in the recess of the opposite part and hold them from slipping on each other. The weight of the carrier and the load it is carrying will at all times be directly upon the cable, or substantially so, instead of being directly upon the sto pieces, as it would be if a sleeve was use or the curved parts N were run the entire length of the pieces L and M. In that case the entire weight of v the carrier and its load would be upon the pieces L and or bend them unless they were made quite strong and heavy.

j The rear wheel standing upon the short curved parts N will not tend to bend or strain the pieces L and M, and the cable will be free to accommodate itself to the strain of the load. The swiveled connection between the parts F and G and L and M should be loosely joined, and there should be sufficient room between the cable and the pieces L and M so that the cable .will be free to spring or bend at all pointsto accommodate the strain of the load.

What I claim is 1. In hay-carriers, a clamp adapted to be applied to a hay-carrier track and having an extension on one end thereof, swiveling means on said extension and a stop device loosely fitted to the track and adapted at one end to embrace the swivel end of the clamp and to turn thereon.
