WILLIAM JEFFERSON CHANCE, OF DAWSON, YUKON TERRITORY, CANADA.

ELEVATED CARRIER.

Specification of Letters Patent. Patented May 5, 1908.

Application filed July 15, 1907. Serial No. 383,789.

To all whom it may concern: I

Be it known that 1, WILLIAM JEFFERSON or abutment block 2, having the depending CHANCE, a citizen of the Dominion of Canada, latch portion or lug 3, at its forward end, and residing at Dawson, in the Yukon Territory the depending counter-weighted extension and Dominion of Canada, have invented cerl 4, at its rear end, which serves to retain the tain new and useful Improvements in Ele- I stop block in the proper'upright position. vated Carriers, of which the following is a The carrier frame consists of two side memspecification. bers 5, each member comprising a top bar or My invention relates to improvements in rail 6, depending end bars 7, an intermediate elevated carriers, and has for its object the longer depending bar or plate 8, a short lower provision of an aerial or overhead conveyor bar 9, connected between the rear end bar system which will be automatic in its operaand the intermediate bar 8, and a diagonally tion, which will be of simple and durable conarranged bar 10, extending from the rear end struction and which will be practical and of the upper bar to the lower depending end efficient in'every particular. of the front bar. These two side members Another object of my invention isthe proare secured together in spaced relation by the vision of an automatic hoisting and convey spreaders or spacing bolts 11, and by reason of the braced construction, the carrier frame is light, compact and very strong. Sheaves 12, are journaled in the upper ends of the frame between the side members, which engage the cable or track and form the roller supports for the carrier.

load sheave 13, is journaled in the front lower end of the carrier frame, preferably at the juncture of the diagonal braces with the front depending braces 7, over which passes the hoisting rope or cable 14, the stationary end of the cable being anchored to the spreader or securing bolt 15.

The forward edge of the depending bar or plate 8. is rounded or curved inwardly and upwardly as at 16, to form a guiding edge, and a complementary guiding edge 17, is formed on the oppositely disposed depending guide plate 18, the depending portions-of the two plates thus forming a gradually narrowing guiding passage. At the head of this guiding passage between the guiding plates, is pivoted the tumbler 19, which is formed with a supporting hook extension 20, which when the tumbler is in the upright supporting position, extends across the opening between the guide plates. As shown in the drawings, one of the spreaders of the carrier frame may be utilized to serve as an abutment, to limit the lower movement of the tumbler. When the tumbler is in this lower or non-supporting position, the upper leg or portion 21, 0f the tumbler extends across the guiding opening.

A latch member 22, is pivoted at 23, in the rear portion of the frame, the upper portion of the latch having a jaw recess therein to engage the lug or tooth 3, on the end of the bumper. The movement of the latch is liming apparatus which may be adapted for a great variety of purposes such as hay conveyers, excavating systems, for coaling ships at sea, and for many other like uses.

With the above and other objects in view my invention consists of a track or cableway, a carrier adapted to travel thereon, a hoisting sheave supported by the carrier, means for automatically locking the carrier at predetermined points on the trackway, and automatic means for releasing the hoisting sheave to lower the load at such predetermined points. a

My invention further consists of an elevated carrier embodying certain other novel features of construction, combination and arrangement of parts substantially as disclosed herein and as illustrated in the accompanying drawings, in which:

Figure 1, is a side elevation of my improved tumbler carrier, with the parts shown in the release or nonsupporting position, the near side of the carrier frame being removed to more clearly illustrate the parts. Fig. 2, is a like view of the device with the parts in the load-supporting position. Fig. 3, is a verti cal sectional view taken through the carrier and sheave frame.

My invention is particularly adapted for use where the cable or track is placed at an incline, as on the side of a hill for instance, and it is illustrated as such in the accompanying drawings. It will be understood, however that I do not limit myself to the use of an inclined trackway, as the invention may as well be adapted for a straight or irregular In the drawings: The numeral 1 designates the cable or track upon which at the desired point is bolted or otherwise secured the stop ited by means of the abutment or spreader tical and satisfactory tumbler carrier which 24.

frame contacts with the tooth on the bumper j or stop block, and the jaw opening in the latch makes locking engagement with the, bumper tooth. The latch thus locks the carrier stationary upon the cable and by the j same movement draws the pawl on the dog from engagement with the angular shoulder on the tumbler thereby releasing the tumbler. The weight on the sheave frame draws the tumbler down, the sheave frame then being free to fall to deposit the load in the proper place. A reverse procedure is gone through with in hoisting the load and carrying to a different location.

From the foregoing description taken in connection with the drawings, the operation and advantages of my invention will be readily understood and appreciated, and it will be apparent that I have provided a prac- Witnesses:
