APPARATUS FOR HANDLiNG MINE-CARS.

(SPECIFICATION forming part of Letters Patent No. 765,902, dated July 26, 1904.

Application filed March 26. 1904. Serial No. 2U0,210. (No model.)

vented a new and useful Improvement in Ap-V paratus for Handling Mine-Cars; and I do hereby declare the following' to be a full, clear, and exact description thereof.

My invention relates to apparatus for handling mine-cars, its object being to provide for the quick handling and discharge of loaded cars as well as the returning' of the empty cars to the point where they are reloaded.

M v invention therefore comprises the novel features hereinafter fully set forth and claimed.

To enable others skilled in the art to make and use myinvention, I will describe the same more fully, referring to the accompanying drawings, in which4v Figure 1 is a plan view of my improved apparatus. Fig. 2 is a side view thereof. Fig. 3 is an enlarged side view of a portion of the apparatus, showing the pusher-carriage for advancing the empty cars onto the elevator and the mechanism for operating the same. Fig. 4 is an end view. Fig. 5 is a plan view of the driving mechanism and the different connections therefrom for operating the apparatus. Fig. 6 is a plan view of the pusher-carriage and the safety-stop for checking the too rapid movement of the car in advancing onto the elevator. Fig. 7 is a sectional detail view of the clutch shown in Fig. 5 for throwing thc mechanism into and out of operation for driving the cndless'chain. Fig. 8 is an enlarged cross-section online 8 8, Fig. 6; and Fig. 9 is an enlarged detail view of the frictional railoperating mechanism.

In the drawings thenumeral 2 represents an elevated structure of proper size and dimensions for supporting my improved apparatus, and said structure may be varied according to the conditions and requirements of different plants. As my invention is used in connection with vertical mine-shafts, thenumerals 3 and 4 designate suitable shafts through which the cars are raised and lowered into the mine, said shafts being provided with any suitable form of elevator or lift L1" for 'raising and lowering the cars to and from the mine. This elevator 4 has a platform with a section of track laid thereon adapted to support the mine-car. (Shown in dotted lines in Fig. 1.) The structure Q is further provided withtipples 5 and 6, where the loaded cars may be dumped; but as any suitable form of tipple or dumping apparatus may be employed and the same forms no part of my present invention it has not been deemed necessary to illustrate the same further than in the dia grammatie form of Fig. 1.

At the rear of thestructure 2 is thekickback 7, upon which thetrack 9 is laid, said track extending forward to a suitable point, where it branches oif into thetrack 10, said track extending to and being in alinement with the track on the elevator-platform and extending still farther forward, where it curves at 11 and unites with thetrack 12 on thekickback 8 at the forward end of the structure. Branching oif from thetrack 9 is the track 13, which operates in connection with theshaft 3, said track extending forward and connecting' with thetrack 12. A return-track 14 connects with thetrack 12, saidtrack 14 leading to theinclined track 15.

Within thetrack 15 is the endless chain 16, mounted on thesprockets 17 and 18, supported within the frame. This chain 16 passes through asuitable guide 19,'above which theprojections 21 extend, said projections being adapted to engage with the car, axle, or other projection and carry the same up theinclined track 15.Idle rollers 20 are employed to support the chain 16 at proper intervals.

Mounted on theshaft 22, upon which the sprocket-wheel 18 is mounted. is the large sprocket-wheel Q2, over which the sprocketchain 23 passes, said sprocket-chain passing' over the sprocket-wheel 24 on theshaft 25, mounted in suitable bearings- 26. Upon theshaft 25 is a large gear-wheel 27, which meshes with the small gear-wheel 28 on theshaft 29. Thisshaft 29 is mounted in suitable bearings, and at the outer end of said shaft is thepulley 30, driven by thebelt 31 from a suitable engine.

ounted on theshaft 29 is theclutch 32, said clutch, as indicated in Fig. 7, being composed of the disks 33 and 34, secured to theshaft 29, said disks being connected by the boltsA toggle connection 36 connects said disks with the sliding sleeve 37 on theshaft 29. Interposed between the disks and 34 is the friction -disk 38, having the wooden friction-blocks 39, said friction-disk 38 being loosely mounted on theshaft 29. Connected with the friction-disk 38 by means of the sleeve 39 is thesmall pinion 28. Alever 40 is connected to the sliding sleeve 37, said lever being pivoted at 41, so that by the movement of said lever the toggle is operated to force the disks 33 and 34 into contact with the friction-disk 38, so as to cause the rota-- tion of same, together with thepinion 28. The outer end of thelever 40 is connected to the rod 42, which in turnvis connected to the crank 43 on the shaft 44. Secured to the shaft 44 is theoscillating bar 45, to the outer ends of which are secured therods 46 46'. To the upper end of thesevertical rods 46 46' are secured the foot-rests 47 47, by means of which said rods are depressed.

Mounted on theshaft 29 are the frictionwheels 48 49, adapted to bear against the faces ofthe friction-wheels 5() 51, respectively. The large friction-wheels 5() and 51 are mounted on theshafts 52, said shafts having at one end the sliding bearings Mounted on theshafts 52 are thepinions 54, meshing with the large gear-wheels 55 upon theshafts 56. On theshafts 56 are thedrums 57. These parts are in duplicate in order to provide for the operation of the mechanism for each shaft.

Connected to the slidingjournals 53 are thelevers 58, extending up to a suitable point in the platform above, where they may be operated by the handles 59. By the operation of these levers the large friction-wheels 50 and 51 may be moved into contact with their corresponding smaller friction-wheels 48 and 49. Cables or belts 60 pass around thepulleys 57 and thence in both directions over the drums 61, where said cables are connected to the front and rear ends of the pusher-carriage 62. This pusher-carriage is provided with thewheels 63, adapted to run on thetrack 64. Pivoted to thecarriage 62 is thepusher 65, which normally extends up in position to engage the mine-car and push the same forward. The pusher, however, is pivoted at 66, so that the said pusher will be depressed when the car passes over the same.

Just in advance of the pusher-carriage 62 is the car-checkingdevice 67, which comprises therails 68, with the curved ends 69, said rails being connected to thebars 70, pivoted at 70,

whereby said rails are capable of being moved longitudinally in the manner fully hereinafter set forth. Connected to the pivotal bars are the weighted levers 71, provided with theweights 72, said levers being adapted to return saidrails 68 to their normal position. The movement of the lever 71 is regulated by thestops 73 and theguide 74, within which the outer end of said lever works.

Connected to the pusher-carriage 62 is thecable 75, to which theweight 76 is secured, said cable passing over thepulley 77. This weight is adapted to return the pusher-carriage 62 to its rearmost position.

When my improved apparatus is in operation, the loaded cars are lifted, by means of the elevator, up through theshafts 3 and 4 into position to be moved from the tracks of the elevator onto thetracks 9, to be carried to the dumping-tipple. As shown in Fig. 1, the car-shaft 4 is in such position, and said car is then advanced along thetrack 10 of the tipple 5, where said car is dumped, and is then advanced forward along the curved track 11 to the track l2 on the kick-back 8, The empty car passes up said kick-back 8, and then descends the same, whence it is shifted otf onto thecurved track 14 to theinclined track 15. When the car passes onto theinclined track 15, it is carried up said track by means of the endless chain 16, one of theprojections 21 of said chain engaging the car. When the car has been carried up to the top of the incline, it descends from the same and passes to track 9 and up the kick-back 7. It then descends from said kick-back and is switched off onto thetrack 10. The impetus which said empty car has acquired carries it forward, and in order to check its movement and prevent it from dropping into the open shaft 4 in case the elevator of said shaft is lowered the wheels of said car engage the longitudinalmovable rails 68, their inner faces being in frictonal contact with said rails, whereby the speed of the car is checked and the car stopped. The flanges of the wheels will run between the rails of the track and the rails of the checking device, and in order to advance said empty car onto the platform 4a of the elevator when the same is up in position to receive the car the operator operates the proper lever 59, so as to throw the friction-wheel 50 into contact with the friction-wheel 48, whereu pon through theshaft 52 and thepinion 54 and gear-wheel 55 power is transmitted to theshaft 56. This will act to rotate thedrum 57 and Wind the cable 60 thereon in such a manner as to advance thepusher carriage 62, so that the pusher engages the emptycar and advances the same onto the platform of the elevator. At the same time the loaded car is pushed by the empty car onto thetrack 10. As soon as the car has been driven onto the elevator the lever 59 is moved in the opposite direction, whereupon the friction-Wheel 50 is thrown out of contact with the friction-Weel 48 and thedrum 57 ceases to rotate in that direction. Theweight 76 oncable 75 withdraws the car- IIO IIS

riage 62 to its normal position, while at the same time the weighted lever 71, which has been raised by the forward movement of therails 68, resumes its normal position and carries therails 68 back to their original position. The empty car is then lowered and a loaded car at the same time is raised inshaft 3 and after beingadvanced to the dumpingtipple passes onto the kick-back 8 and returns in the same manner as above described to the kick-back 7, whence it passes to the similar apparatus as that just above described in connection with shaft 4, whereupon the empty ear is held in check until the platform of the elevator is in position to receive the same,when it is advanced onto the elevator in the manner before described.

In case it is desired to stop the movement of the endless chain 16 for any reason, as in case where the empty cars are becoming congested at the rear end of the apparatus, the operator by putting his foot on one of the foot-rests 47' acts through the connections described to operate thelever 40, so as to throw the clutch in-such position as to render thepinion 28 inoperative, whereupon the power transmitted through said pinion to the large gear-wheel 27 and thence to the large sprocket-wheel 22 is shut off.
