JOSEPH I. POTTER, OF INDIANAPOLIS, INDIANA.

AERIAL-CABLE HOISTER AND CONVEYER. v

T 0 all whom it may concern:

Be it known that I, JOSEPH L. POTTER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Aerial-Cable Hoister and Conveyer, of which the following is a specification, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon.

This invention relates to movable apparatus adapted for hoisting and conveying and adaptable for excavating and conveying operations, the invention having reference particularly to apparatus of the above-mentioned character that is designed to be shipped knock-clown and to be readily set up for use wherever required.

The object of the invention primarily is to provide improved hoisting and conveying apparatus that will be adapted to be moved as the work progresses and capable of conveying the earth from trenches relatively long distances and dumping the earth backinto the trenches; a further object being to provide apparatus of the above-mentioned character that will be adapted to be constructed atrelatively small cost and in a compact and substantial manner, and which will be durable and economical in use, minor objects being apparent from a perusal of the description of the invention.

The invention comprises essentially two frames provided with wheels to constitute cars, each car having a tower mounted thereon, means for looking or anchoring the cars to prevent movement thereof during operations, an overhead or aerial cable supported by the towers, and a carrier having wheels mounted movably on the cable; and the invention consists further in the novel parts, and in the combinations and arrangements of parts, as hereinafter particularly described and claimed.

Serial No. 621,226.

the different figures of the drawings indicate corresponding elements or features of construction herein referred to.

In practically carrying out the objects of the invention a suitable rectangular car frame 1 to constitute a part of a head frame or car is provided and its normally rear end is mounted on a pair of wheels 2 and 2 having toothed wheels 3 and 3 thereon or so connected that both must move together, the toothed wheels preferably being of the spurtooth type. The forward end of the frame is mounted on similar carrying wheels 4, and preferably additional wheels A support the middle portion of the car frame. The frame has a floor 5 built thereon which, preferably, does not extend entirely to the rear end of the frame. Two locking dogs 6 and 6 are mountedon the opposite side portions of the rear end of the frame and normally engage the toothed wheels 3 and 3", respectively, for preventing movement of the car, the dogs being so mounted that they may be disconnected from the toothed wheels to permit the car to move. The carrying wheels of the car are preferably flanged, and when the car is setup for operation the wheels are supported and guided on rails 7 and 7 arranged at opposite sides of the plane in which the excavating is to be done, the rails usually resting upon stringers 8 and 8. A suitable hoisting engine is mounted upon the forward end portion of the car frame and comprises a frame 9, engine cylinders 10 and 10', a boiler 11,

a winding drum 12 provided with a brake operating arm 13 and a winding drum 14 provided with a brake operating arm 15. Engines of this character being well known require no further description. A suitable frame is erected upon the opposite end portion of the car frame at a suitable distance from the rear end to constitute a part of the head frame or car and preferably comprises two vertical posts 16 and 16 on the top of which a cap beam 17 is secured, a beam 18 frame thereon constitute a unitary movable head frame or forward frame which in practical use is moved as occasionally required in the direction indicated by arrows thereat.

A forward tower is arranged at the rear end portion of the frame 1 and is preferably supported on pivots 20 and 20 suitably mounted upon the frame adjacently to the rear side of the posts 16 and 16'. The tower preferably comprises two standards 21 and 21 provided with journal boxes 22 and 22 embracing the pivots so as to aiford conveniences for permitting the tower to be lowered or raised. The standards are inclined each toward the other, and a capbeam 23 is secured to their upper ends. A beam 24 is secured to the standards and is secured to the beam 18 by means of bolts 25 which hold the standards against the stopblock 18. Preferably other beams 26 and 27 are secured to the standards, the tower structure preferably having cross-braces 28 and 29. Two sheaves 30 and 31 are mounted in the upper portion of the tower, prefer-' ably on shafts 32 and 33 mounted on the standards. A saddle 34 is mounted on the top and another saddle 35 is mounted on the rear side of the cap beam 23, the saddles being on the middle portion of the beam and preferably are formed on a single casting. A guy rope or cable 36 is seated at its middle portion in the saddle 35, and its end portions are secured to the forward end portion of the frame 1, or if desired may extend forwardly as indicated by dotted lines in. Fig. 1, so that it may be anchored to the ground beyond the movable forward frame, the latter arrangement being desirable in some cases if the towers or masts are spaced apart an extremely great distance. The forward tower may readily be detached from the forward frame after disconnecting the cable 36 from its anchorage and removing the bolts 25 to permit the tower to be lowered to the ground.

An open base rearward or tail frame is provided which preferably comprises two sills 37 and 38, preferably of compound construction, and the forward ends thereof are mounted on carrying wheels 39 and 39 provided with toothed wheels 40 and 40 connected thereto so that each carrying wheel and a toothed wheel must move together, the rear end portions of the sills being mounted on carrying wheels 41 and 41. The carrying wheels are preferably flanged, so as to be guided on the rails 7 and 7 Dogs 42 and 42" are mounted movably on the sills so as to normally engage the toothed wheels 40 and 40 removably. A post 43 is secured upon the sill 37 some what rearward of the forward end thereof, and a post 43 is secured upon the rear end portion of the sill, similar posts 44 and 44 being similarly secured upon the sill 38.

A rectangular top frame comprising beams 45 and 45' extending longitudinally, and transverse beams 46 and 46 extending transversely are secured to the upper ends of the four posts. A diagonal brace 47 is secured to the upper portion of the post 43 and to the lower portion of the post 43, a similar brace 47 being likewise connected to the posts 44 and 44. A beam 48 is secured to the rear side of the upper portions of the posts 43 and 44, and a stop block 49 is secured to the forward side of the posts at the upper portion thereof. It will be seen from the foregoing that there is clear space between the two sills of the rear or tail frame and from the ground up to the beam 48, so that the frame may span the trench and also span the ridge of earth resulting after filling the trench. Suitable provision is made for loading the rear end of the rear or tail frame, and preferably two beams 50 and 50 are placed upon the beams 45 and 45 and support a box 51 in which a suitable number of weights as 52, 52 are placed, any suitable character of weighting material obviously being permissible. An open base rear tower is provided which is some what similar to the other tower and preferably is supported upon pivots 53 and 53 mounted on the forward end portions of the two sills, the tower preferably comprising two standards 54 and 54 provided with journal boxes 55 and 55 embracing the pivots detachably, the standards converging upwardly and having a cap-beam 56 secured to the upper ends thereof. A beam 57 is secured to the standards opposite the beam 48 and is secured thereto by means of bolts 58 and 58 so that the standards are held tightly against the stop block 49. Horizontal beams 59 and 60 are secured to the upper portions of the standards, and preferably the tower is braced by means of crossed rods 61 and 62. A saddle 63 is mounted upon the beam 56, and another saddle 64 is mounted on the forward side'o'l. the beam, the two saddles preferably being formed as a single casting. A guy rope or cable 65 is seated at its middle portion in the saddle 64 and its ends are secured to the rear upward portion of the rear or tail frame, or as illustrated by broken lines in Fig. 1 it may extend outward beyond the rear frame to be anchored to the ground. A sheave 66 is mounted in the upper portion of the rear tower preferably on a shaft 67 supported by the standards 54 and 54. It will be seen from the foregoing that the rear or tail frame may be moved to a suitable or desired position and then locked against movement by means of the dogs 42 and 42.

A cable 68 is seated in the saddle 34 and also in the saddle 63, one end portion 68 of the cable being brought down alongside of one of the standards of the forward tower 73 mounted thereon and also a pair of sheaves 74 and 75 mounted on the lower portion of the frame. A pulley block 76 is em-; ployed which is provided with a hook 77. Any suitable excavating implement or hoisting device may be connected to the hook, in

the present case a scooping bucket 78 provided with a bail 79 being shown for the purpose of illustration of the invention, the:

bail being connected to the hook. The

pulley-block has a suitable pulley 80 mount-' ed therein. A cable 81 is connected with the windingdrum 12 and extends over the sheave 30, thence over the guide-pulleys 72 and 73 and around the sheave 66, thence over the sheave 75, around the sheave 80 and thence over the sheave 74 and connected at} Another. cable 82 is connected to the winding drum 14 and extends over the sheave 31 to the; frame 70 to which it is connected. Then the winding drum 12 is operated it is evi-l dent that the carrier may be drawn toward the rear tower if the winding drum H bev allowed to run loose, or if prevented from; turning the load may be lifted. If the wind-i ing drum let be operated the cable 82 will; draw the carrier toward the forward tower In practical use the two towers are ar-f ranged oppositely each to the other at a suitits end to the pulley block 76.

able distance apart, and the distance may be varied as occasion may require by merely 'readjusting the cable 68 and moving one or the other of the movable frames. The excavating and the sewer construction work may be accomplished conveniently between the two towers, the earth being usually removed near the forward tower and then conveyed and dumped upon the finished work near the rear tower, the earth being piled up to form a ridge which may be passed over by the rearward tower and its supporting frame. In some cases the excavating implement may require'to be worked rearward of the rear tower below its supporting frame and dragged forwardly, which operations may be conveniently performed with the present construction. It will be understood that the movements of the hoisting or excavating implement are quickly controlled by the operator at the hoisting engine.
