'To all whom it may concern/. I

Be it known that I, FlannnaroK RJFRENCH,

a citizen of the United States,'residing in the. city and county of San Francisco, State of 1 California, have invented an 'll'nprovement in Conveying Apparatus; and'I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to an apparatus designed for transporting burdens in bothhori zontal and vertical directions;

It consists of parallel'suspended cables inclosing any area and adapted to operate between four supports, a transverse burdencarrier movable between said supports,'and

means for also moving the burden-carrier transversely between the cables and at any point between the supports, whereby thebur-I den can be transferred toanyp'oint within the area and raised or lowered withoutan independent mainfall-line? v My invention also comprises details of construction, which will be'more fully explained by reference to the accompanying'drawings, in whichj e Figure 1 is a general perspective view of the apparatus. Fig. 2 is a view of the sheaves which are attached to the top of the towers. j Fig. 3 shows'the arrangement of the trolleys tion, depending upon the contour of theground or theposition where the apparatus is to be operated. Spars or timbers with, suitable guys or supports may serve, or builttowers or where the contour of the ground is suitable the elevation'of the ground may serve, for the support of'the cable-carrying sheaves. The sheaves upon" the towers A B are constructed as shownin Fig. 2, in'whioh three different pulleys 2, 3, and 4 are-turna'bleupon pins in a single frame or frames, as at 5, and these frames or blocks are suitably connected with the towers or supports by links, as are, or other suitable connections,

which will allow the parts'to yield to the changing positions or strains upon which pass around them.

the cables 7 and 8 are two drums, connected so as to and 9 and 10 10 the first two passingaround the drum 7 and the second pair aroun'dithe Around these drums passcables 9 6o drulnl8. The cables 9 and 9 and 10 10. may

either -.be separate and have their ends secured to their respective drums or they may be continuous andwound around the drums,

is drawn in.

10 pass, respectively, aroundthe sheaves'2,

As sho'wnin the drawings, vthe cables 9 and thence beneath guiding-pulleys 11 upontrol- 'ley-carriers 12', thence around pulleys 13, at-

tached to the upports 0 and D,-thence reu ning to-the point whereithey are attached to the trolley-carriers, as at 14, the other cables .9 10 passing from'the'oppositesides p Y of the drums 7 and 8 around" thesheaves't of the tower-blocks 5, thence "to the trolleycarriers 12, to which-theyare'attached, as at": I 14 of the cables10. Bythis arrangement it :1 33 will be 'seen that whenever'thedru'ins'are re 15, upon the sides opposite to'the attachments volved in unison in either'direction-Ithe trol-f .1ey-carriers12 will be silnllltaneouslymoved outward awaylfrom the towersA and 13 or of revolution of the drums;

51 toward the towers, according tothe direction: e

.The trolley-carriers l2 maybe-of any' it,

able form or construction I *Iha've here shown I them as triangular framesjin: one angle of "whichthe pulleys or sheaves 11 are journaled,

and in theother two'anglesare journ'aledthe sheaves 16. and 17. '.-18'- and' 19 are two drums re'volu'bleinunt "son and around whichare wound the ropes 20 and 21in such a manner that one of said ropes wil pay out or be lengtheneiwh il it I a other will be correspondingly drawn'in'or shortened. The rope 20 passes outwardly around the sheave'3 of the *towerIA', "thence around the sheave 16 of the tr01ley-'carrier,'

thence around a sheave 2,2, which is journaled in a frame or block connected with the burden-support, thence around the sheave 17 of ,65 if p the object in either casebeingfthat'one cable e p of each pair should pay out while theother c The operation of the device will then be as follows: The two drums 7 and 8,1'evolving together, if they are turned so that their top sides move to the left the cables will be coiled and uncoiled upon the drums in unison, so that the trolleys will move in unison toward the engine. If the drums are reversed, the cables will cause the trolleys to move in the opposite direction or away from the engine. While this motion is taking place, the burden will remain at the same relative position between the trolleys 12,having first been lifted from the surface by the operation of the drums 18 and 19 and the

cables

20 and 21. Thus a burden having been lifted from a point near the tower A may be transported by the movements of the drums 7 and S and the cables 9 and 10 to a point near to the tower G, and then by the operation of the drums 18 and 19 and the

cables

20 and 21 it may be transferred transversely to a point near the tower D, after which by stopping one of the drums 18 or 19 and allowing the cable to uncoil from the other the load may be lowered by the lengthening of the supporting-cable and deposited at any desired point. In this manner the load or burden may be picked up at any point within the area between the towers or supports A B C D and transferred to any other point within said area and there deposited.

If it is desired to make aerial dumps, as in discharging loads of earth or rock, it may be elfected by any well known or suitable device employed for such purposes.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination in a conveying apparatus of parallel pairs of suspending-cables, supports over which said cables pass, winding-drums around which the cables are movable, trolleys suspended and movable upon the cables, other cables passing around sheaves in said trolleys and a burden-carrier suspended by said cables between the parallel cables, and means by which said burdencarrier may be moved transversely between the parallel cables.

2. The combination in a conveying apparatus of pairs of parallel cables, supports over which said cables pass, trolleys suspended and movable upon the cablesanechanism by which said cables are moved to cause the trolleys to travel outwardly or inwardly in unison, a burden carrier, supplemental cables from which the carrier is suspended between the parallel cables, and means for actuating the supplemental cables to move the carrier transversely between the parallel cables.

The combination in a conveying apparatus of two sets of parallel inhaul and outhaul cables, trolleys with which said cables are connected from opposite sides whereby said trolleys are movable in unison, a burdencarrier and supplemental cables by which it is suspended between the parallel cables, guidesheaves upon the trolleys and upon the fixed supports, and winding-drums by which the supplemental cables are actuated to move the burden transversely, or to raise or lower it.

4. The combination in a conveying apparatus of two pairs of parallel inhaul and outhaul cables,with direction-pulleys overwhich they pass, trolleys movable one upon each of said parallel cables, and with opposite sides of which the ends of the cables are connected whereby the trolleys are moved in unison, and a burden-carrier and supplemental cables by which it is suspended between the trolleycarriers, and means by which the cables are actuated to raise or lower the burden or to move it transversely between the parallel cables.

5. The combination with pairs of parallel cables and their actuating mechanism, and trolleys suspended and movable upon the ca bles, of supplemental cables connected to the trolleys, a burden-carrier connected to the latter cables, and means for actuating the supplemental cables to cause the burden-carrier to be moved transversely between the parallel cables.

6. The combination in a conveying apparatus of two sets of parallel inhaul and outhaul cables, trolleys with which said cables are connected from opposite sides, windingdrums by which the cables are driven and the trolleys moved in unison in either direction, supplemental winding-drums and supplemental. cables connected and movable thereby, guide-sheaves upon the towers and the trolleys, and a burden-carrier connected to the supplemental cables and located between the main cables, and capable of being moved transversely thereby between the parallel cables.

7. The combination in a conveyingapparatus of two sets of inhaul and outhaul'cables and winding-drums operable in unison to move the cables, trolleys to which the cables are connected at opposite sides, and supplemental cables passing over sheaves in each of the trolleys, a bundle-carrier suspended from the supplemental cables,winding-drums, guiding-sheaves, and connections whereby the fall is operated without a standing cable.
