Application filed March 28, 1893. Serial No. 468,009. (No model.) Patented in France March 17,1898, No. 228,713 in Belgium March 18,1893. No. 103,897, and in Italy June 23,1893,LXVIL 118.

To all whom it may concern:

Be it known that I, J OSEPH TEMPERLEY, ship-owner, a citizen of England, residing at Wray Lodge, Reigate, in the county of Surrey, England, have invented a certain new and useful Traveling Pulley-Carriage for Raising, Lowering, and Traversin g Loads, (for which I have obtained Letters Patent in France, dated March 17, 1893, No. 228,713; in Belgium, dated March 18,1893, No. 103,897, and in Italy, dated June 23, 1893,Vol.LXVII, 118,) of which the following is a specification. For the purpose of raising, lowering and traversing loads as from the hold of a vessel to a quay or barge or conversely, or from one part to another of a warehouse, factory, wharf, railway or other yard, an overhead track is often provided, having a winch, or crab arranged to travelalong it. Certain inconveniences attend this arrangement, resulting from the necessary weight of the winch and the difficulty of applying power to it.

A main object of my invention is to avoid these inconveniences by placing the winch stationary in any convenient position and arranging simply a pulley carriage to travel along the overhead track, this carriage being provided with automatic locking and unlocking mechanism such that it can be stopped at any desired part of its travel and will remain stationary while the load is raised or lowered by the rope or chain passing over the pulley from the winch. This pulley carriage when the pulley is looked is drawn along the track in the one direction by the winch rope or chain; it is drawn in the opposite direction by a counterweight, or, in cases where the track can be conveniently inclined, it may run down by gravity. A convenient form of track for such a pulley carriage is a flanged girder, the carriage having wheels which roll on the flanges of the girder. I shall therefore describe a pulley carriage according to my invention arranged to run along such a girder referring to the accompanying draw- Ings.

Figure 1 is a vertical section of the carriage in condition for raising or lowering, Without traveling. Fig. 2 is a side elevation showing the carriage in condition for traveling along the track without raising or lowering the load. Fig. 3 is a front elevation. Fig. 4 is a plan the girder and wheels being removed to show the cams below. Figs.5 and 6 show details. Fig. 7 illustrates the application of the apparatus for loading or unloading at a wharf.

In these figures similar letters denote like parts.

The upper part of the carriage consists of a frame having two side cheeks A A with four wheels (1, to roll on the flanges of the girder B two on each side of its web.

To the frame A is jointed at c c the'under frame of the carriage, having two side cheeks C 0 between which is mounted the pulley D free to turn upon a pin 01 on which is also mounted, free to turn, a lever frame having two side cheeks E E between which passes the rope F carrying the load. The lower part of the lever frame E E is formed as a fork at e e. A pair of arms 6 e projecting from E E have pivoted to them at e a pawl lever having a pair of long arms e between which the rope F passes and a pawl e which can engage with one or other of a set of ratchet teeth on a segment 0 which is fixed between the cheeks O O and which forms at its lower end at c a rest for e e. The cheeks E E are connected by a bolt 6 in such a position that when the cheeks move round the pin (1 this bolt can enter the gab of a cam G pivoted on a bolt 9 between the cheeks A A. Another cam H is in like manner pivoted on a bolt h between the cheeks A A. The cam H is wider than G and has a groove to receive G. Both the cams G and II have curved slots through which passes a bolt I, this bolt also passing through horizontal slots in the side cheeks A A. The cam H has also aprojecting horn h which can engage in a notch 70* or h in a piece or pieces MM fixed where desired to the under side of the girder B, and in a groove of H is pivoted a pawl k having a heavy lower arm. The curvatures of the cams G and H have portions at their lower ends radial.

To the cheeks A A is attached a rope or chain K which passes over a pulley at the exthe following manner: When it is in the con- 1 dition shown in Fig. 1 the horn h of the cam H being engaged in the notch k or it might be in a notch 71. at another part of the girder, the carriage cannot move because the bolt I is in the radial part of the slot of H preventing H from turning in either direction so as y to disengage itself from the notch h or h The load can then be lowered by slacking out the rope F or raised by hauling it bya winch In raising the load, the rope F or otherwise. passes between the cheeks e" and if it should rub against either of them it might tend to raise them with it. This is prevented by the pawl e engaging with a tooth of c. When the load is so far raised that theblock L on the rope F comes up to the lever arms 6' between which the block cannot pass, it raises these arms throwing the pawl e away from the teeth of c, and the block L still rising moves the lever frame E E round to the position shown in'Fig. 2. During this movement the bolt e entering the gab of G moves G partly round causing the bolt I to slide along the horizontal slots in A A and so far along the slot of H that H can be turned by its horn 7t disengaging itself from the notch h or 71 this movement of H moving the belt I still farther along the horizontal slots of AA and along the slot of G to the terminal part which is radial G being thus held stationary and holding the lever frame E E in the position shown in Fig. 2. In this position the block L being over the forks e is held stationary locking the pulley D, and now it being disengaged the whole carriage can be pulled to the left byhauling F or allowed to be drawn to the right on slacking out F, the load being thus carried along without being raised or lowered. While II moves round as above described to the position shown in Fig. 2 its pawl 72. is turned into the notch 71 as shown in Fig. 5, but as that notch has its right side slotted the pawl can pass through the slot when the carriage travels to the right. When however the carriage is pulled to the left, the pawl k is turned over into the position shown in Fig. 2, and then when the carriage travels to the rightthe pawl is stopped by a shoulder at b, so that H is again turned to the position shown in Fig. 1, turning G so as to release e and thus allowing the lever frame to be carried down by the block L when the rope F is slacked out. Thecarriage now being held as before by the engagement of h in the notch, the load can be lowered or the end of the rope F can be lowered to take up a load which can be raised, the carriage remaining stationary until the block L again releases it and locks the pulley D. Pieces M each having a notch 7L2 and a shou1- der I) being fixed to the girder B at various places, the operator can at any of these places lock or release the carriage releasing or locking the pulley; he has only to haul the carriage by F to the left untilthe end of the pawl htpasses theshoulder I). Then on slacking out F, when h meets b the carriage will become locked and the pulley released as in Fig. 1, and will so remain until the ascent of the block L again releases the carriage and locks the pulley. The cheeks C C of the lower part of the carriage might be fixed to the cheeks A A of the upper part. I prefer however to joint the two parts together by pivots c 0 so that there may be freedom to swing without throwing the wheels at off the track.

As shown in Fig. Z, the girderBis inclined so that when the rope F is slacked out, it can run by gravity to the right. A numberof the pieces M are shown on the under side of the girder to allow of locking and unlocking :as above described in a number of different places. When an inclinedgirder is employed as shown in Fig. 7, the vertical line of rope below the pulley, instead of being in the direction shown at F in Fig. 1, will take a direction relatively inclined as indicated by the dotted line W, the anglemade by F with F being equal to the inclination of the girder. It is therefore necessary to adjust the segment 0 and with it the lever frame E E to this condition. This is done by providing several holes at c to receive the bolts by which the segment 0' is fixed to the cheeks O 0. Also to allow for the consequent change of position of E E, several holes are provided to receive the bolt e according as the girder is less or more inclined to the horizontal.

Having thus described the nature of my said invention and the best means I know for carrying the same into practicalettectfl claim- 1.
