Specification of Letters Patent.

Patented Sept. 24:, 1907.

Application filed June 17,1907. Serial No. 379,461.

To all'whom it may concern:

Be it known that I, JOSEPH M. GRIFFITH, a citizen of the United States, residing at Cardiff, in the county of Harford and State of Maryland, have invented a new and useful Conveyer, of which the following is a specification.

This invention relates to conveying mechanism of that general class in which a wheeled bucket or carrier is traveled on an elevated cable or support between filling and dumping position.

One of the principal objects of the invention is to provide. an improved means for insuring dumping of the load at any desired point.

A further object of the invention is to provide a dumping device supported by an adjustable carriage and arranged to be engaged and to form a rest and stop for the fall block and the load carrier.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the'form, proportions, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings :Figure 1 is an elevation of a conveyer constructed and arranged in accordance with the invention. Fig. 2 is a detail view on an enlarged scale of the dumping mechanism prior to the dumping operation. Fig. 3 is a sectional plan view on the line 33 of Fig. 2.

Similar numerals of reference are employed to indi cate corresponding parts throughout the several figures of the drawings.

Extending between suitable towers or posts 10ll is a cable or track-way 15 that extends over the loading pit or point A and the dumping point B.

Mounted on the cable is a fall carriage 16 having a pair of supporting wheels 17 that are grooved for the reception of the cable, and from the shafts of these wheels is hung a frame 18 carrying a pair of sheaves 19 and20.

Below the sheaves 19 and 20 is hung a fall block 21 having a pendent hook 22 on which is hung a tiltable load receiver 23. The fall rope 24 is connected at one end to the frame of the fall block, thence passes up around the sheave 20, down under the fall block, up over the sheave 19, and from thence around suitable guiding sheaves to the hoisting drum E.

The hoisting drum E is arranged to be operated from an engine F that is located adjacent the post 11, any suitable means being employed for controlling the connection and disconnection of the drum and engine. The engine is, also, arranged to operate the drum G over which passes the intermediate portion of a fall cable 28 that is guided by suitable sheaves at the top of the post 10. The lower run of the fall cable is connected to the carriage 16 at 29, and the upper run of this cable extends to the distant post 10 where it passes around a sheave 30, and thence runs back and is connected to the carriage 16 at the point 3]., so that by turning the drum first in one direction afid then in the other direction the carriage 16 will be traveled between the loading and dumping points. Above the dumping point is arranged a carriage 35 having supporting wheels 36 that rest on a cable 15 and which may be locked thereto in any suitable manner, the position of this carriage being adjustable in order to vary the dumping point. l-hpm the shafts of the supporting wheels 36 is hung a frame 38. On this frame is pivoted a lever 41 having a bifurcated lower end that is arranged to form a pair of hooks 42 which are arranged to receive the opposite ends of a bar 43 that projects from the frame of the fall block. The rear portion of the lever 41 is pivotally connected with the bifurcated end of a rod 46, the opposite end of said rod having a number of spaced openings through any one of which may pass a bolt 47 carried by a depending bracket 48 on the frame of the carriage, this rod being adjustable to vary the extent to which the hooks project from the forward face of the carriage 35.

When the load receiver is in the position shown in Fig. 1 and is loaded, the winding drum G is turned and the cable 24 is wound up until the load receiver is fully raised. The fall block and load receiver are then held up by maintaining the friction on the drum E and the drum G is then turned-for the purpose of pulling on the upper run of the pull cable, so that the carriage 16 will contact with the stop carriage 40. The drum G is then stopped and the drum E is released allowing the fall block to settle until the cross bar 43 engages in the hooks 42. On further downward movement the load receiver will be tilted to the position shown by dotted lines in Fig. 2 by reason of the fact that the rear or closed end of the load receiver is connected to the frame of the fall block by a chain or bar 50.

After the dumping of the load, the hoisting cable is again wound up until the fall block is clear of the hooks, and then the haul cable is operated for the purpose of drawing the carriage and load receptacle back to the loading point.

I claim 1. In conveying mechanism, a supporting cable or track, a dumping carriage on the cable, a fall block, a fall block carriage, a hoisting rope connected to the fall block a traction rope connected tothe fall block carriage, a bar projecting from the frame of the fall block, a load receiver, the rear edge of which is connected to said bar, and hooks adjustably secured to the dumping carriage and with which said bar engages.

be run along the supporting cable until it comes into 2. In conveying mechanism, a dumping carriage, a lever pivoted thereto and provided at its lower end with a pair of spaced hooks, a rod adjustably connecting the lever to a portion of the carriage, a fallblock carriage arranged to travel on the cable, a fall block, a hoisting rope carry ing the fall block, a traction rope connected to the fall block carriage, a bar projecting from the fall block frame and provided with a pair of laterally extended arms arranged to engage the hooks, a load receiver, and a connecting means between the rear portion of the load reeeiver and the bar.

3. In mechanism of the class described, a supporting cable, a fall block carriage arranged to travel thereon, a fall block, a frame carrying the same, a hoisting rod having one end connected to the frame and extending around the fall block, and thence to a winding mechanism, a bar projecting from the fall block frame, a load receptacle hung from the fall block frame, and connecting means between the rear end of such receptacle and the frame, a dumping carriage supported by the cable and including a wheeled frame, a lever pivoted to said dumping carriage and having a bifurcated end provided with terminal hooks for engagement with the bar of the fall block, an adjusting lever connecting the hooked lever to the frame of the dumping carriage, and a haul rope, the ends of which are secured to the fall block carriage, the intermediate portion of the haul rope passing around the winding drum.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
