Subordinate objects are to provide a movable loading 'means which is coupled to and carried'forward-by the 15 traveling bucketfor a predetermined distance," the contents of said loader being discharged into' the bucket during the period of' such travel; toprovider means which will automatically uncouple said loader, when unloaded, from the bucket and'return s'ameto' starting at the city of St. Louis and State 10f Missouriyhaveim vented certain new and useful Improvements in Aerial Tramways,-of which the following is- 'a specification,

A clip 12 is secured to the trolley beam 2, said clip being tightened seas constantly Ward by gravity, and this bill terminates in chutes 14, ,one chute being providedon'each side of the tramway system] iAutoma'ticallybperated gates 15 close said i chutes when the reed or cm are be stopped, as, in additiom haid g'atesimay be'iadjusted to regulate the amount of orewhi ch can pass through chutes 14in any given-period of time. 7 Chutes. 14 discharge theore into I 6 5 is located the travelinghoppers 10 while said dPP rsare. at rest, and these-hoppers, in turn; ivhile moving,.empty their contentsinto bucketil l I p The travelingloadr'comprises apair'of l 1oppe1s ;10 which are respectively located on'opposite sides of-the track cable 7 or track8 and which are, furthermoree suitably 'united' together to ms 'unitaryij structuref Because of this provision and arrangemeutoia plurality of hoppers, i opposite sides er e; path oi the bucket 1, ore can be discharged; intobuc ket l from both sides,

instead Jof frorn oirIy one, as has" heretofore been the practice, Many importantfadvantages havebeen found to arisefrom this improyedconstruction, among which may be mentioned .the fact that the traveling bucket can'be loaded in half thetime otherwise required; and

the distance which-.the travelingv loaderm'ust cover.

thereby- 'cut in'half, so that the costof constructing the loading. stations is materially reduced ;the fact that the ,load ofi'ore is-niore evenly distributed and moreloosely packed'iin'the traveling bucket; so that.it will empty more readily andewilltravel with less tendenc'yto cause the trolley sheaves'h to bind on the track cable 7, 'which binding necessarily occurs where the center of gravity of the loaded bucket is very much to one side, asis the case wherathe ore is unevenly distributed or dumped in a single heap in the bucket; the fact that even =dis- ,tribution tends to reduce many strains onthe entire system which a would otherwise bei-Zpresent, thereby helping to prolong the life of all parts; the fact that the weight borne by the traveling loader is evenly dis- I .Itribut'edon'each side thereof; and the fact that'said" leader can be actuated at or near its center of gravity,

at a point midway between the two hoppers, instead of being drawn from one corner or one side as customary in present practice, where the traveling bucket actuates a single hopper, thus allowing the hopper-carriage I 5' to move easily and with little, if any, tendency for. the

,10 beams 17, from which beams thefhoppers are supported, and by'which they are connected.- Sheaves 18 are journaled .upon suitable axles .which are secured either to cross-beams 16, as in Fig; 3, or to longitudinal beams 17, as in Fig. 2, said sheaves traveling upontracks 19, so that the loader canmove back and forthon said tracks, carrying lr'oppers 10 therewith, said hoppers discharging their contents into the bucket 1 while the parts are in motion.

In order to insure the travel of the loader at the same 20 time bucket-1 is passing through the loading station,

means are provided for locking said 'loader to said bucket, or the trolley beam supporting same, and for releasing said members from such engagement at a predetermined point. To this'end, pintle 9. projects outwardly from trolley beam 2, as hereinabove set forth,

and, as the bucket lpasses through the loading station; said pintle locks with'the pivoted and spring-pressed actuating levers 20, which levers are adapted to cause the loader to start forward slowly but gradually to increase in speed until it travels at the same rate as bucket I. Said levers, also, serve as a buffer to obviate the I 40 otherwise mounted, however, as by brackets secured to the framework of the loader. Said levers are disposed ,in the path of travel of the pintle 9, and are engaged by said pintle as the bucket 1 passes through the loading station "Said actuating levers occupy, when the loader is at rest, the approximately vertical position depicted in full lines in the left hand end of Fig. 2, and the heli-, cal springs 22, one end of each of saidsprings being secured to one of said levers 20 and theopposite end to shaft 21, tend to keep said levers normally in such ver-' tic al position, to resist any forces which operate to pull the levers out of such vertical position, and to return the le'vers to the position depicted in the left hand end, Fig. 2, when they are so moved by the action of the pintle 9, as presently described. 5 5 When the pintle 9 strikes levers 20, said ieversyield slightly against the resistance of springs 22, but, at the same time, as the pintle presses the'levers forward in the same direction as the pintle itself moves, the levers, in turn, cause the' loader to move forward as well. As

the bucket 1 continues to move and pintle 9-to bear on t the inwardly-curved edges 23 of levers 20, the levers are gradually swung upward as the springs 22 yield, the

, levers, of course, moving forwardand causing the loader aiter'which the traction'cable 11, being then'connected to the loader, will draw'the loader along at the same rate of speed as the bucket itself is moved. During I springs 22 are tightened by the rotation of levers 20 around shaft 21, said loader reaching the maximum.

velocity when the pintle. 9 catches in the hooks 24.

Inasmuchas it is desired to have the loader thus travel for only a predetermined distance and during such length of time as will enable the contents of the hoppers 10 to be discharged into. the bucket 1, it 'is cross-connectsthe ends of levers 20 opposite'the hook-- like ends 24, so that these levers move in unison, and upon said shaft rollers 25are journaled. In the'path of travel of theserollers a releasing-trip 27 is inter-' posed, which trip is adapted to depress the upper ends of levers 20, thereby'to elevate the hook-like ends 24 and disconnect the same from thepintle 9. Trip 27 is from traveling too far, and this buffer may be ofany desiredv form and can be placedwherever convenient; v As one illustration, the drawings show the ends of the rails 19 bent-upward at 19 so that sheaves 18 may.

' suspended from the framework of the loading-station strikethereagainst, thus positively limiting the forward movement of the loader, 'as well as imparting a slight return impulse thereto; The rails 19 are set at an incline, so that as the loader movesforward as above described it travels on an. upgrade. When, however,

the levers 20 are released from the pintle 9, the loader is no longer drawn forward, but is free to return to the starting position depicted at the left hand end of Fig.- 2. To secure such return and make it automatic, a counterweight 34 may be provided, said counterweight its being suspended at one end of a rope 35, which rope passes over apulley 36 and has its opposite end secured to any convenient part of the loader, as, for example, the beam 16., ,It is not necessary in all cases to provide this counterweight, and generally it will be found sufficient to set the rails;19 at an incline, so that the'carriage, can return by'rolling down grade. As the loader thus returns, springs 22 cause-the levers 20 toresume the vertical position, and, when. the loader has returned to the left" hand end of Fig. 2, the levers 20 willbe in place so that the loader is ready for another trip as, soon as the, hoppers 10 have been refilled.

, When the ore is discharged from chute 14 into hoppers 10 it would fall to the ground were not'some means provided for closing the mouth 30 through which the ore passes from the hoppers into the bucket. Accordingly, a bulkhead 31 is secured to the framework of the loading station, said bulkhead being properly braced, as at 32, and so placed that when the hopper 10 is in starting positionit willbear thereagainst with mouth 30 immediately behind'said bulkhead and closed thereby. As hopper 10 is drawn forward (toward the right, Fig. 2) in the manner hereinabove described, mouth 30 gradually rides beyond the end of bulkhead 31, and the ore drops through said month (now unobstructed) into the bucket l beneath. Theedge of the bulkhead flares as'at 33 toward the'side opposite that against whichthe hopperrests, so that the loader will slide into position, on its return movement, without having the hoppers l0 strike against the outer edge of said bulkheads.

When the pintle Q strikesthe levers-20, there is a tendency for the reaction to cause the bucket to rise up, and thus derail the trolley sheaves 6"from the' track 8. To obviate this,.a guide 37 is provided, said guide being bolted or otherwise secured to the loader at 38. The apex of the trolley beam 2, is curved as-at a position that the curved ape2t39 strikes thereagainst before coming into contact-with the guide 37, the spring thereby serving partly to absorb the shock which occurs when the traveling bucket picks up the loader to carry same forward. In lieu of having the. apex, 39 I curved, a roller may be journaled in thetrolley beam or on pintle .9, said roller,.instead of the curved top 39,

strikingagainst .guide 37 ,1 this construction being, in many cases, thepreferred form. l To eschouhem-ms 41 of pendant 3 plates 42 are secured, and in, these plates latches-4 are pivoted, there being one such latchat each side'of bucket 1, said latches beingadapted to hook over theprojecting ends.

of brackets 5 and thereby keep the bucket 1 locked in upright ,position. A shaft 43 is journaled in blocks 44 which are fixed to the pendent arms 41. Links 45, ec-

centrically pivoted to the ends of shaft 43 or to crankarms 46 which are fixed upon said shaft, connect theshaft to latches 4, so that rotation of the shaft causes links 45' to raise the latches 4 and thereby allow the bucket l to be released so as automatically to dump its contents. A handle 4.7 is secured to shaft'43, and a trip 48, similar in construction and arrangement to trip 27,

- ,c'anbe-pla ced at. any desiredpoint'in the system, said trip serving to depress the handle 47 and, thereby, to

release the bucket so that it will discharge its contents automatically;

The trolley beam 2 is preferably triangular in shape, thesheaves 6 being journaled adjacent the two lower angles while the pintle 9 passes through the beam near the apex thereof. ,Pintle 9, inaddition to serving as a convenient'means for actuatingthe load er, is the axis for roller 39, and, fiirther, supports the bucket 1 from the 'beam, 'pendant 3, in which the bucket is held,-looping over said pintle. Projecting outwardly from'trolley beam-Zeta point bel ow pintle 9 isan extension 49 upon which clip 12 is mounted, saidclip being provided to' engage the traction cable 11 by which the various mov-' ing parts are drawn forward.

To each ore gate 15 one arm of a bell-crank lever 50 is secured, saidle'yer, on being rocked, serving to open $5 the gate. An operating lever 51, fixed to a rock-shaft .52, rocks shaft, swings the crank arm '53 which isfixed upon said shaft. As said arm 53 is swung, link 54 is pulled, thus rocking the belLcrank 50 and thereby opening'the gate .15. It should be understood that the levers 51 are moved automatically so that the gates 15 are opened. at the proper time to fill the hoppers l0, and are'closed' as soon asa sufficient quantity of ore-has passed down thechutes 14. .Sa'id; automatic mechanism,- however, forms no part of the present invention,

and-is not herein described orshown in detail, the leve'rs 51 being represented conventionallyand as capable I of manual operationonly.v

The operation of the system isas followsz-The clip 12 having been tightened upon the-traction cable 11, said cable draws the bucket 1 forward (toward the right, .Fig.

. 2), said bucket being supported from the trolley beam 2 which travels on track S or cable 7. bucket I'enters the loading station, 'pintle 9 engages thelevers 20, and, as the trolley beam2, which carries-the pintle, continues to move forward, levers 20 are simultaneously pressed forward and upward, thus actuating'tlie loader and causing same to travel atja gradually increasing rate of speed until, at length, pintle9 engages'thehook-like ends 24 of levers 20, after which the leader, and the bucket 1 will travel in unison for a predetermined time.

When the upper ends of levers 2O strike the trip 2 7 and are depressed thereby, thehdok-like ends are elevated and thus forced out of engagement with'the pintle 9,

thereby stopping the forward actuation ofthe loader andpermitting said loader to return; automatically to starting position. The bucket l continues'on its way, and, at anydesired point in the system, the operator may, manually or-automatically, tripthehandle 47,

which operation releases the latches 4, thus-permitting the bucket to become inverted and to discharge its contents. The bucket, thereupon, rights itself, and,- as the track 7 .and traction cable 11 are endless, the bucket will in due time be returned to the loading'station where it can be reloaded as above. When the hoppers; are in starting position (at the left, Fig. 1) they are filled by ore which runs down chute 14, .gate 15 being opened just long enough to permit thehoppersto be filled.

The ore is retained 'in hoppers '10, the mouth of the hoppersbeing closed by the bulkhead 31, but when the loader is movedtoward the right, Fig. 2, mouths 30 of hoppers 1 0 are carried clear'of the bulkhead, and the ore thus permitted-todrop into the buckets 1.- At each succeeding operation the hoppers-are recharged from chute 14, as before, so thattheloading and unloading of buckets 1 and hoppers 10 becomes a continuous and automatic operation, which is repeated ed libt'tum, or

as long as the traction cable 11 is kept in motion.
