ELEVATED TRAM WAY.

SPECIFICATION formingpart of Letters Patent No. 643,114, dated February 13, 1900.

Application filed May 2'7, 1899. Serial No. 718,598. (No model.)

To aZZ whom it may concern: Be it known that we, SAMUEL FLORY, residing at Bangor, and J OHN MARSHALL YOUNG,

residing at Easton, Northampton county,

. State of Pennsylvania, citizens of the United construction in which the gripper shall be automatically caused to grip the cable by the weight of the load with sufficient force to carry the load up any degree of incline and yet no injury he done to the traction-cable.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a sufficient portion of a cableway-terminal to illustrate the operation of the invention. Fig. 2 is an enlarged side elevation of the carriage. Fig. 3 is a view at right angles to Fig. 2.

In the drawings, A represents the stationary elevated way, in this instance a cableway, upon which thecarriage runs, and B the endless traction rope or cable, both of these being supported in the ordinary or any desired manner. Above the end of the cableway and. continuing beyond the said end is the supplemental way 0, which effects the automatic release ofthe grip in the manner hereinafter described. The tramway carriage frame is indicated at D and is provided with the wheels E, which travel upon thestationary cable and normally support the load. A bail-bar F, designed to carry the bucket, has its upper end provided with a lateral extension or trunnion guided in a vertical slot or guideway cl in the carriage-frame. A second vertical bar G, connected to this trunnion f, extends upward to a point above the cable- 'way and is provided with a wheel 0', designed to coact with the supplemental rail or way 0 upper face, this jaw being preferably adjustably secured upon abutments D of the carriage-frame and having a guiding-shank extending down between the same.

An upper movable jawK is provided, having its lower face curved to correspond to the face of the lower jaw, this jaw being guided by a stem or projection 70, entering a slot L in the frame. (Jams M are pivoted to the frame, one on each side of the upper shoe, having their faces designed to coact with the shoe to force the latter down to clamp the cable between the upper and lower shoes, and these cams are operated by links N, pivotally connected at one end to the cams and at the other end to a downward extension of the bar G. It will thus be seen that when the carriage is at the terminal, as shown at Fig. 1, and is being loaded or unloaded the wheel 0' rests upon the supplemental track, and as at this point the cableway descends out of the path of the main wheels the entire weight will be borne by the supplemental wheel, thus drawing upward upon the movable shoe through its lateral extensions K, which rest upon the lugs w, extending from the link N, to release the grip.

After the bucket has been filled or dumped, as the case may be, the carriage is shoved by hand. to the terminus of the supplemental rail,where the wheels of the frame pass onto the cable-rail, and the release of the supplemental wheel from the rail 0 permits bar G to descend under the weight of the bucket and through the links and cams force the movable jaw down to firmly clamp the traction-rope between it and the lower jaw. The carriage is then firmly gripped to the traction-rope and remains connected with it until the other terminal is reached, when the supplemental wheel again passes onto the supplemental rail or way and the carriage-wheels pass from the cableway, permitting the relative movement of the frame and bar G to release the grippers.

It will be observed that after the load at terminal has caused the jaws to grip the rope it also firmly locks them, so that any diminishing of the load by reason of climbing stifi grades will not diminish the pressure upon the grip on cable, as by reason of the shape of the cam-faces any upward movement of the shoe will be resisted, and it can only be raised by first moving the cams.

Having thus described our invention, What we claim is- 1. In an elevated-tramway system, the combination with the main way and supplemental Ways, of a wheeled carriage designed to run upon said main way, stationary and movable gripping-shoes carried thereby, a bar verticall y movable of said frame, a wheel carried by said bar designed to coact with said supplemental rail, cams operatively connected with said movable bar and bearing on said movable shoe, and means for suspending the bucket from said movable bar, substantially as described.

2. In combination with the supplemental and main ways, the wheeled carriage, the sta tionary and movable shoes carried thereby, the verticallymovable bar guided by said frame and carrying a supplemental wheel, cams pivoted to said frame and bearing against said movable shoe, links connecting said cams with the movable bar, and means for connecting thebucket to said movable bar, substantially as described.

3. In combination, the carriage-frame,the stationary lower jaw, the upper jaw vertically guided thereon and having inclined side faces, the vertically-movable bar guided in said frame, the cams pivoted to the frame and bearing against said inclined sides, and links connecting said bar and cams, substantially as described.

4. In combination, the main. way and terminal supplemental way, the carriage-frame, the main supporting-wheels carried thereby normally engaging said main way, the sliding bar carrying the load, means carried thereby adapted to engage the supplemental way, a stationary gripping-jaw secured to said frame, a movable gripping-jaw and means for clamping said jaws when the sliding bar is held depressed and said bar is out of engagement with said way, substantially as described.

In testimony whereof we affix our signatures in presence of witnesses.
