SPECIFICATION forming part of Letters Patent No. 788,861, dated May 2, 1905.

Application led June 1G, 1904. Serial No. 212,906.

To all 'wlmi/1t it may concern:

Be it known that I, JOHN L. WTAGNER, a citizen ofthe United States, residing at Fairmont, in the county of Marion and State of Test Virginia, have invented certain new and useful Improvements in Oable-Hauls, of which the following is a specilication.

My invention relates to cable hauls or similar systems in which interengaging devices are provided on cars and on an endless cable, whereby the cars are automatically picked up by the cable at one point and delivered to another point.

My invention consists in certain novel combinations of features and details of construction hereinafter fully described, and particularly pointed out in the claims, reference being mad e to the accompanying drawings, forming part of this specification, in which Figure l is a vertical sectional view of that portion of the system at which the cars are picked up by the cable. Fig. 2 is a similar sectional view of that portion of the system where the cars are. released, suitable driving machinery for the cable being also suggested. Figs. 3 and i respectively show a vertical transverse section and a partial plan of brakingl mechanism automatically operated in the system` for retardingI the cars at the point where they are released by the cable. Figs.

5, 6, and 7 respectively show a side elevationv of the inter-engaging devices on the car and cable, a bottom plan of the engaging' device applied to the cars, and a top plan of the engaging device or trolley, of which a number are applied at suitable intervals on the cable. Figs. 8 to ll illustrate further features of my invention, whereby the dogs are raised and held in elevated position prior to or upon entering the mine in order to avoid fouling with obstructions while the car is in the mine and released so that they can gravitate to engaging position when or after the car leaves the mine, Figs. 8 and l() being, respectively, a side elevation and a bottom plan View of the car-dogs with the centrally-disposed rail for raising' said dogs into engagement with suitable detents, and Figs. 9 and 11 being a side elevation and a bottom plan view, respectively, of the dogs with the laterally-disposed rails for releasing the detents.

the car-track connecting with A where the carsare to be picked up by the cable, inclined upwardly to reduce the momentum of the cars, and O the portion of the track where the ears are discharged by the cable, usually given a slight downward incline in order that the cars will proceed by their own momentum after being released to a dumping-point-such, for instance, as a tipple. D represents any suitablev type of driving machinery for the cable, which may conveniently be located adjacent to the dimming-point for the cars. Vhcn cars are discharged from the mouth of the mine, it is desirable to have them move off promptly, and for this reason the portion of the track A is given a considerable incline downward, and for this reason itis customary, even though the dumping-point is lower than the point B, to provide an incline at B suiiicient to reduce the speed of the cars to what it should be. The cars are indicated by dotted lines at 5 and their wheels at 6. '.lhe engaging device carried by these cars is represented at 7 and comprises dogs 8 9, suitably pivoted beneath the car-body in a manner to permit them to gravitate into engaging position. The engaging devices on the cable comprise trolleys A, running on suitable tracks and carrying blocks l0, in front of and behind which the dogs 8 and S) drop for engagement. The distance between the dogs is such that when either dog is in engagement the other dog can swing upward out of engaging position. One feature of my invention consists in providing interengaging means on the cars and on the cable, comprising' pivoted dogs on the cars, adapted to swing upward out of engaging position, and a block on the cable, in front of and behind which thesedogs are adapted to engage, so as to conline the car relatively to the cable in both directions. Under some circumstances, particularly when the cars are light, it is desirable to have means for holding the cars on the track upon which they run. Another feature of my invention therefore consists in providing the blocks l() with suitable undercuts l1, as shown by dot- IOO ted lines in Figs. 5 and 7, and the dogs 8 9 with projections 12, adapted to enter the undercuts 11, so that the interengagement of the devices 7 and 4; holds the cars down upon their tracks, the tautness of the cable being sufiicient to prevent the trolleys 1 from yielding upward. VVheu a car moves rapidly down the incline A, dog 9 will readily ride over the block 10 should the car overtake one of the trolleys 1 near the bottom of the incline B and when the car is moving at a much greater rate than the cable; but if the dog 8 should strike block 10 at such a time there is danger of either breaking some of the parts or derailing the car. Another feature of my invention consists, therefore, in providing between the delivery-incline and retarding-incline means for raising' the rear dog on the car and holding it out of engaging position until such time as the momentum of the car is largely overcome and. its rate of movement reduced to approximately that of the cable. One embodiment of such means is illustrated in the drawings as comprising a lifting-rail 13, arranged along the track with an inclined front end and in position to engage the rear dog or a part thereof-for instance, through the lateral projection or pin 18 on the dog. This lifting-rail will be to one side of the dogs or otherwise arranged so that it affects the rear dog only, and, as suggested by the breaking away of the end and its continuance in ,dotted lines, it may extend to any desired point, the front dog being allowed to hang in engaging position, so that the car will be picked up by the cable as soon as sufficiently retarded to be overtaken by one of the trolleys.

1f the projections 12, entering the undercuts 11, are not used, the trolleys will naturally sink below the line of engagement with the dogs when the car reaches the position shown in Fig. 2, at which point the cable is below the surface of the track; but since it is preferable to have this interlocking of the dogs with the trolley it is necessary in order to release the dogs from the trolley to permit a disengaging relative movement between the trolley and the dogs engaged therewith by raising one of the dogs and then to cause such relative movement as will result in the remaining dog becoming' disengaged. 1f the depression of the cable relatively to the track takes place on the upgrade, it is obvious that the front dog would be in engagement, and therefore that the rear dog would have to be raised previous to reaching such point of depression and thereafter the car accelerated relatively to the cable-as, for instance, by a slight downgrade in the track-just before the point of depression is reached, which would draw the projection 12 on the front dog out of the front undercut 11, after which the car is free to continue under its own momentum to the dumping-point; but if there is downgrade in advance of the point of depression a sufficient distance to cause the rear dog to engage the trolley then it will be necessary to raise the front dog andto retard the car to unlock the rear dog just before the trolley drops below the plane of the track. Another feature of my invention therefore consists in combining with the interengaging and interlocking means on the car and cable means for raising one of the dogs, so as to permit a relative disengagiug movement between the trolley and the other dog, and means for causing this relative movement when the parts are in position to permit it to take place. The embodiment of this feature, which I have illustrated, is shown in Fig. 2 of the draw-v ings, where the car is on the downgrade, and therefore has to be held back by the engagement of its rear dog with the trolley. The lifting-rail 13it is on the opposite side of the dogs from the lifting-rail 18, previously described, and has lifted the dog 9 by its laterally-projecting pin 18u, (shown in dotted lines in Figs. 2 and 5 and in full lines in Fig. 6,) also an automatically-applied brake, which is more clearly understood upon reference to Figs. 3 and 4, wherein 14 represents brakeshoes adapted to impinge the sides of the carwheels. 15 represents thrust rods by which the shoes 14 are carried. 16 represents pressure-plates at opposite sides of the trolleytrack, and 17 represents antifriction-rollers projecting from the sides of the trolley in position to impinge the plates 16 as the trolley passes between them to force the brake-shoes 14 against the wheels 6. By this construction, as will be seen, I provide not only automatic means for moving one dog out of engaging position to permit relative movement between the car and trolley in the direction of the raised dog and automatic means for causing this relative movement to take place, but also means causing this relative movement to take place which is automatically actuated by the trolley and specifically a means for retarding the car automatically actuated by the trolley.

Rails 13 and 13, with their cooperating dogs, provide automatic means for lifting the dogs at suitable points along the tracks, said means being alternated on opposite sides of the track and each dog being provided with its special engaging means, so that one dog may be affected independently of the other.

As is well known in the usual operation of single-cable hauls, the cable is used both to run the cars out and to return them. I have only illustrated the outgoing track in my invention; but it is obvious that the principles here explained are applicable in returning the cars, and the lifting-rails and means for releasing the dogs from their engaging positions that the trolley may be depressec may be located at any point where it is desirable to have the several functions of these parts performed.

IOO

, Ihere is a decided advantage for some purl poses in having dogs mounted on the car instead of on the trolley, as proposed. This location of the dogs facilitates the use of means for controlling their positions and for moving them out of engaging position. Moreover, gravitating-dogs can be employed with very much less complication than when the dogs are mounted on the trolley. Vi'hen the dogs are carried by the car and necessarily enter the mine with the car, they vvill be liable to meet obstructions of coal or other solid matter lying between the rails of the track, and thus be in danger of becoming broken. The same conditions may be encountered in other uses to which my cable-haul system is applicable. To avoid thisdanger, I provide further features of my invention, one of which consists of a centrally-disposed liftingrail 19, having an inclined end 19, upon which the dogs 8 and 9 ride either before or immediately after the car enters the mine or enters upon any portion of the track Where it may be desirable to hold the dogs in elevation or at some other suitable point, While detents.20, swinging in bearings 21 and having counterbalance-arms 22, are adapted to engage the pins 18 18 on the dogs when the latter are raised up and hold said dogs in elevated position until the detente are released. In order to release the detents and permit the dogs to drop into engaging position after the car leaves the mine or reaches a portion of the track Where it is desired to have the dogs or either` of them in effective position, laterally-disposed releasing-rails 23 are put into position to lift the connterWeight-arms 22 as they ride up on the incline 23, and thus permit the dogs 8 and 9 to drop. It will be understood that the rail 19 will be on the track by which the cars enter the mine, lWhereas the pair of rails 23 Will be on the track by which the cars leave theV mine. rIhe exact points at which these rails are located may be selected according to the time in the passage of the car when it is desired to have the several functions performed. Obviously the rail on that side of the dogs which releases the rear dog can be located at a different point in the track from the rail which is utilized to release the front dog. The dogreleasing rail may often be located on the knuckle at the point at which it is desired to drop the rear dog behind the block on the cable, in which event the Vlifting-rail 18, heretofore described, need not be employed to prevent the rear dog from striking the cableblock before the momentum of the car has been overcomewthat is to say, the detentfor the rear dog and its releasing-rail together serve as the means for holding the dog ele* vated at the desired point and dropping it behind the block when the momentum of the car is overcome.
