Like numerals of reference refer to corresponding parts throughout the different views of the drawings.

The reference numeral 15, designates a portion of an elevated track which may be made of a more or less flexible cable, or of rigid material, and suitably supported at the desired elevation from the ground. This track may have secured thereon at a suit able point a depending bracket 16, on the lower portion of which may be pivotally secured a trip 17, which is free to move upwardly in one direction, but restricted in its movement in the other direction, in order to enable the carrying apparatus which travels on the track 15, to pass said trip when going in one direction, without being influenced thereby or, in other words, without having its trigger thrown thereby, but when the apparatus travels in the other direction, said trip will contact with. the trigger of the apparatus and throw the same. Adapted to travel on the track 15, are wheels 18, both of which are journaled or. the upper end of depending hangers 19, each of which hangers is provided at its lower end with a downward extension 20, having a head 21, on its lower end. Each of the extensions 20, of each of the hangers 19, is swiveled or rotatably mounted in the upper portion 22, of an upright bracket 23, one of which is employed at each end of the truck or main frame which is designated as a whole by the reference numeral 21 see Figs. 1, and 2, of the drawings, thus allowing the wheels 18, to turn at various angles with relation to the truck frame, so as to permit the carrier to easily round curves and to be brought into exact alinement on a straight stretch of track. The truck or main frame of the apparatus comprises two parallel members or rails 25, and 26, which are spaced some distance from one another and have their end portions inturned or approximated and secured to the brackets 23, below the heads or upper parts 22, thereof, in which parts the extensions 20, of the hangers 19, are swiveled. The side rails or members 25, and 26, of the truck or main frame 24, are braced near each of their ends by means of transversely disposed bars 27, and inwardly of each of such bars by means of a similarly disposed bar 23, which bars not only act as'braces for the side rails or members 25, 26, of the truck frame, but also serve to support shafts 29, one of which is roescea journaled on each pair of the bars 27, and 23, and longitudinally with respectto the truck frame as will be clearly understood by reference to Figs. a, and 8, of the drawings, in the latter of which figures as well as Fig. 2, it will be seen and understood that the upright brackets 23, on which the ends of the side rails 25, and 26, of the truck frame 21, mounted, are located on one side of the longitudinal axis of said frame. Mounted on each of the shafts 29, is a drum 30, which has fixed to its outer end a gear 31, one or both of which gears has on its outer surface an annular extension or brake drum 32, against which extension a brake band 33, contacts, one end of which band is secured to one end of an arm 34, which is mounted at its further end on one side of the truck frame 24:, near one end thereof, and said arm projects upwardly and in ardly toward the extension 32, as is clearly shown in 9, of the drawings. Pivotally secured on the arm 3 1, is a dog 35, one end of which is adapted to engage the teeth of the gear 31, and has pivotally connected thereto the end of the bracket banc 33, opposite that which is connected to the arm 34;, so that, when the inner end. of the dog is disengaged from the teeth of the gear 31, which may be done by means of a cord or connection 36, attached to the outer end of the dog the band 33, may betightened on the extension 32, and its frictional contact therewith in creased or regulated so as to govern the movement of the drum 30, to which the brake controlled gear 31, is connected. Connected at one of its ends to each of the drums 30, is a chain or other flexible connection 37. the other of each of which is connected to a bail 38, which is herein shown as being formed of channel iron, or as having a channel on its outer surface, but which may be tubular or of other construction. As shown, this bail. is substantially of an inverted U-shape, and has pivotally mounted between its lower or free ends a car or receptacle 39, of any suitable size, shape and material, which is employed for holding the material to be transported from place to place by the apparatus. The upper portion of the bail 38, is disposed horizontally as shown in Fig. 1, and projects some distance above the points at which the flexible connections 37, on the winding drums 30, are connected, so that when the bail and carrier are raised to operative position for transferring a load, the upper port-ion of the bail will extend through the open truck frame 24, or between the side rails thereof,

in which operation it will be understood that the drum or winding shafts 30, are journaled at one side of the upright brackets of the truck frame, and that as the cords or connections 37, are unwound from and wound on said drums, at their surfaces adj acent to a longitudinal line drawn through the frame 24, and through the brackets 23, thereof, the bail 38, and the receptacle 39, will be operated on a vertical line from the track 15, so that when the bail is raised to its uppermost position it will. lie directly under said tracks so that the trigger which the bail carries will be in position to contact with the trip 17, on the track as will be presently explained.

Mounted on each end of the car 39, or receptacle, is a locking plate 40, which has at its lower portion a bearing 41, to each of which one end of the bail 38, is pivotally connected. These plates 40, are mounted on the receptacle or car 39, so that their bearings 41, will be nearer the bottom of the receptacle than its top, when the same is in its upright or loaded position, in order that its upper portion may be heavier than its lower part. to the end that, when the car is released or unloaded from the bail it will automaticall tilt on its bearings. The upper portion of each of the plates 40, is upwardly curved and is provided with a recess to receive a projection 43, or locking bolt, with which each of the weights 44, is provided, which bolts extend through suitable openings 44, in the lower portion of the bail near each of its ends, and are projected from weights 45, one of which is located in the bail near each of its ends.

The upper or horizontal portion of the bail 38, has pivotally mounted thereon at about its middle portion an upwardly extended trigger 46, which is substantially of an inverted U-shape as shown in, Fig. 6, of the drawings, and has extended in opposite directions from the lower portion of each of its sides, arms 47, to the outer ends of each of which is loosely secured a connection 48, the other ends of which are secured in pairs to a movable member 49, one of which is located in the channeled portion of the bail 38, on each side of the trip 46, and is movably held in said channel by means of a trap 50, which is extended over the member 49, and secured at its end to the sides of the bail. The outer end of each of the members 49, has secured therein a screw hook 51, to each of which is attached one end. of a chain or flexible connection 52, which connections are extended downwardly in the channel of the bail and are connected at their other ends to the weights 45, which carry the locking bolts for the receptacle. By this arrangement it is evident that when the car 39, and bail 38. are in their raised positions as shown in Fig. 1, of the drawings, the trip 46, will be projected into the path of the trip 17, and that in the progress of the apparatus in the direction indicated by the arrow. the trip 17. will contact with the trigger 46. and throw it to about the position indicated by dotted lines, in which operation it is evident that the weights 45, will be drawn upwardly by reason of their connections with the arms 47, on the trigger, thus removing the locking bolts 43, from the recesses 42, of the plates 40, on the receptacle, thereby releasing the latter and permitting it to turn on its pivots and discharge its load.

Instead of making the trigger of the shape shown in Fig. (3, and above described, the trigger 4-6, of the construction shown in Fig. 7, may be employed, which trigger consists of an upright portion pivotally secured at its lower end to one side of the bail 38, having at its upper portion a horizontally disposed part 46 which is projected over the bail and so as to extend into the path of the trip 17, on the track.

A modified construction of the straps used for movably holding the members 49, in place on the bail, is shown in Fig. 7, which may be sometimes employed, and which con sists of an angular piece 50, secured at its lower end to one side of the bail and extended at. its upper portion transversely thereof and above the member which it guides. In the modification of the trigger shown in Fig. 7, the lower portion thereof is provided with arms 47, as in the other const-ruction, and said arms are connected by means of links or connections 48, to the members 49, at one side only thereof.

Journaled on laterally disposed extensions 53, with which the uprights 23, of ,the frame are provided below said frame, and longitudinally therewith is a main shaft 54, which has at one of its ends a grooved wheel 55, over which is passed an endless chain 56, which hangs down a suiiicient distance to be within easy reach of the operator and by means of which the shaft 54, may be turned. This shaft is provided with a pair of pinions 57, at suitable points thereon to engage the gears 31, on the drums 30, so that when the shaft 54, is turned in the proper direction the drum or winding shafts 29, and the drums 30, thereon will be rotated in the proper direction to wind the connections 57, thereon and thus raise the car to the desired position where it will be held by means of the dog 35, which engages the teeth of one of the gears 31. hen it is desired to lower the car, it is apparent that by pulling downwardly on the car 36, the dog 35, will be released from the gear, when the car will descend by reason of its gravity, in which operation its descent can be regulated by pulling down on the car 36, which will tighten the brake band 33, on the extension thus retarding the movement of the car.
