To all whom it may concern:

Be it known that I, VILLIAM LOUDEN, a citizen of the United States, residing at Fairfield, in the county of Jefferson and State of Iowa, have invented a new and useful Improvement in Elevators and Carriers, of which the following is a specification.

My invention relates to elevators and carriers having a receptacle attached, and it consists of improved means whereby the receptacle may be elevated and lowered, and be held at any desired point of elevation without the use of clutches, ratchets, brakes or other similar contrivances, as set forth in this specification and more particularly specified in the claims.

In the accompanying drawings forming a part of this specification, Figure l is a perspective of an elevator and carrier embodying my invention. Fig. 2 is a vertical section on a longitudinal plane showing a portion of the elevating gear. Fig. 3 is avertical cross section on line 3 3 of Fig. 1. Fig. 4 is the same on line ldd of Fig. 1. Fig. 5 is the same on line 5 5 of Fig. l. Fig. 6 is a perspective of a portion of the device showing a modification. Fig. 7 is a detail in perspective showing a modification.

Referring to the drawings, A represents an elevated track upon which a pair of trucks B are mounted. The trucks are connected together by a horizontally disposed bar C, (which is preferably a piece of pipe) to the ends of which castings D are secured, and to these castings the trucks are swiveled thus forming a carrier frame. The castings D are extended down below the bar and are fitted with bearings in which a shaft E is mounted so as to rotate therein. A bracket F is preferably secured to the bar C near its center and is extended down and is fitted with a bearing so as to support the center of the the shaft. A chain or rope wheel Gis secured to a projecting end of the shaft E and a chain or rope I'I is hung in this wheel so that the shaft may be rotated by an operator below. The shaft E is threaded between the castings D and the bracket F, the screw on one end being right handed and the screw on the other end being left handed.

J represents two threaded blocks one being fitted With right hand threads and the other with left hand threads to fit the threads on the end of the shaft upon which each block works. Each of the blocks J is fitted with a guide loop or eye Kl which is arranged to encircle the bar or pipe O and slide thereon while the shaft E is being rotated and the blocks J are being moved thereby. The object of these guide loops are to hold the blocks J from rotating while the thread of the shaft E is turning in them. In this way the blocks J are each drawn correspondingly in toward the center bracket F when the shaft E is rotated in one direction; and are then returned correspondingly toward the adjacent casting D when the shaft E is rotated in the opposite direction. The castings D are preferably fitted at their lower ends with two sheaves I, over which wire cables K are adapted to run.

L represents a boX or receptacle adapted to hold the material to be elevated and carried. It may be constructed in any desired manner but is preferably provided with means at each end, as the hangers M to which the cables K can be attached. After being connected to the hanger M, the cable is passed over one of the sheaves in the casting D adjacent to it, and is then passed around a sheave N in the adjacent block J, then back around the other sheave I in casting D and then back to an eye O in the block J Where it is fastened. The block J on the opposite end of the shaft E is also provided with a similar sheave N and the cable connected to the other end of the boX is passed over and around the sheaves I and N in the casting D and the block J on this end of the carrier and is secured to the block J the same as on the opposite end. It will be seen that by this arrangement, as the shaft E is rotated so as to draw the blocks J in toward the central bracket F, the receptacle L will be elevated by means of the cables K, and that as the shaft is rotated in the opposite direction the receptacle will be correspondingly lowered. The receptacle being sus ended at each end by the cables K, will be eld securely in its horizontal position and will be prevented from tilting endwise should one end be loaded heavier than the other.

i The arrangement of the sheaves and cable shown in Figs. l and 2 will cause the receptacle to be raised and lowered three times the distance that each of the blocks will move, while in Fig. 6 the arrangement shown will cause the receptacle to be raised and lowered twice the distance that each of the blocks will move. In this case the cable after passing over the sheave I in the casting D is passed around the sheave N in the block J f may be equally drawn or released at each end and will simultaneously raise and lower each end of the receptacle, but my` invention is not limited to this double end construction. A shaft having a single screw may be used upon which a single block is mounted, as

shown in Figs. 2 and 6, and to this single block a single cable may be secured in any suitable manner, so that the horizontal movement of the block will cause the receptacle to be elevated or lowered substantially as described. Any suitable kind of receptacle may be used only in this case it should be arranged so that the cable will be secured to a central point instead of at the end as will be readily understood by those skilled in the art without a special figure to illustrate it. Also, instead of a thread being cut upon the shaft, a casting having a screw S 'may be secured to the shaft E, as shown in Fig. 7.
