CABLE- RAILWAY G RIP.

SPECIFICATION forming part of Letters Patent No. 478,773, dated July12, 1892.

Application filed May 27, 1887. Renewed February 18, 1891. Serial No. 381,811. (No model.) Patented in England September 29,

To all whom it mayconccrn:

Be it known that I, CHARLES VOGEL, of the city and county of San Francisco, State of California, have invented a new and Improved Means for Operating Grips of Cable-Railway Cars, (for which Letters Patent of Great Britain, No. 13,194, dated September 29, 1887, were granted me,) of which the following is a specification.

This invention relates to those cable-grips which operate in subways, one part, however, being equally applicable to the corresponding device which in an electric railway operates in a subway to make connection with the conductor, as will be hereinafter pointed out.

This invention constitutes an improvement on the invention describedin Letters Patent of the United States granted .to myself and Whelan, No. 359,043, dated March 8, 1887, in which patent is shown a peculiar grip, in which the jaws, pivoted together, are set at a level which will permit them to grasp the cable as it rests upon its pulley-supports, said jaws being shown therein as carried upon hangers rigidly secured to the car-body and as being operated by a vertically-moving grip-shank.

The object of my present invention is to give the jaws of said patent a vertical move ment, so that while in their normal position they are at or nearly at a level which will permit them to grasp the cable as it rests upon its supporting-pulleys, yet they are susceptible of being thrust farther downward to a level which will permit them to grasp the cable where it may sag between the pulleysupports or to escape contact with an overhanging depression-pulley and the like. To this end the hangers supporting the jaws are made to constitute part of a vertically-movable frame supported by springs which normally hold it up against a stop connected with the running-gear-such, for instance, as the car-axles Dso that,while the springs permit of the jaws being thrust downward to any extent required, the stop determines the highest position of the jaws, so that the springs cannot lift them above the level or near the level necessary for grasping the cable as it rests on the pulley-supports. This position, being measured from a stop on the running-gear, is

unaffected by the motions of the car-body. The verticallymoving frame carrying the jaws is also made to carry the mechanism by which the jaws are opened and closed, so that the opening and closing of the jaws are substantially independent of the vertical movements of the jaws. Mechanism is also provided whereby the operator may thrust the frame downward,when desired, in antagonism to the springs, which mechanism should be of such a character as to admit of the jaws returning to their normal position upon receiving any powerful upward thrust, so that if the jaws should be thrust downward to grasp the sagging cable between the pulleys they may be automaticallyraised by the upward thrust of the cable it approaches the pulley-support to prevent any jamming action at that point. The downward thrust of the jaws is therefore a yielding thrust, such as the pressure of a lever actuated by the attendants foot.

In the accompanying drawings, forming part of this specification, Figure 1 is a sectional elevation of a portion of acar and subway suflicient to illustrate the application of myinvent-ion. Fig. 2 is a plan of the details of my invention detached from the car. Fig. 3 is an edge view of the hand-lever.

In all the figuresthe same letters of reference are used to indicate the same parts.

A is the car-floor; B B, the springs over the axle-boxes, upon which the car-body rests. C C are the wheels, and D D the axles. These parts are not in any way changed. In the drawings, however, for convenience of illustration I have shown the axle-boxes, pedestals, and supporting-springs arranged inside,

the wheels, as usual in dummies or grip-cars, instead of outside, as more commonly found.

E E are a couple of elastic hangers, each comprising a spiral spring e, supported on a plate 6, which rests on the head of the central bolt 6 hanging from the car-floor above. On the top of these springs there will rest the plates e from which there will depend the bolts 6 which, passing down between the side bars of the equalizing-frame F, support the same on broad washers e resting upon their lower heads. This equalizing-frame F is composed of two longitudinal bars of angle-iron set a distance apart equal to the thickness of the upright portions G of the gr1p-frame, which pass betweenthe bars and to which they are riveted. The space between the an gle-irons also constitutes a passageway for the grip-shank, which lies between the uprlght portions G. The an gle-irons are also a little longer than from center to center of the axles, under which they bear with a constant upward pressure. On each end of these bars there are fastened short pieces of the same-shaped iron f. These bear snugly against the sides of theaxle and cause the whole frame to act as a draw-bar to move the car in either direction.

G is the stationary part of the grip-frame, terminating at the top in the usual notched quadrant. This frameis fastened by rivets or bolts to the equalizing-frame only.

The stationary part G and the equalizingframe 1*, considered together, may be said to constitute the grip-frame, and when thus considered the grip-frame is vertically movable;

but otherwise the frame G is stationary.

H is the moving shank of the grip, which is raised and lowered by the hand-lever I and intermediate link J to open and close the grip-jaws K. The lower portion of lever I and the link J may be said to constitute toggle-links.

L is the cable.

M is the subway.

N is one of the carrying-pulleys.

O is a foot-lever of the second order, having its fulcrum at one end in the crotch of the stirrup-bolt P, which is bolted to the floortimbers. It is pivoted on the pin Q of the hand-lever and has a foot-plate R at the opposite end. \Vhen the foot is pressed down upon this lever, the entire frame of the grip is carried down with it, though immediately the foot is released the grip will return to its normal position. WVith the lever 0 arranged, as described, to depress the grip-frame, which also supports the jaws, the downward pressure of the lever will be in a line equidistant between the springs E, whereby the jaws may be thrust vertically downward.

S S are small parallel timbers framed into the cross-timbers of the car-floor. They act as a sort of guide for the grip-frame and are set just far enough apart to accommodate it.

The hand-lever I is formed of two piecesthe handle end and the fulcrum endthese being separated a distance apart suflicient to accommodate the pawl and quadrant between, the two pieces being joined together by side plates '6 i, riveted to them, as shown. The fulcrum-pin of the pawl t" is at the extreme end opposite its point, the lifting-rod 2' being connected between. (See Fig. 1.) An ordinary. spiral spring wound around the rod 1' expands between the head of the pawl and a projecting stop 2' fastened to the lever. The rod '6 is fastened, as usual, to the releasinglevervl, which is pivoted to the main lever on the opposite side to that which receives the applied power in-gripping the cable.

The grip illustrated in the drawings need not be described in further detail, the one here used for illustration being what is shown in the Vogel and Whelan grip, patented March 8, 1887, No. 359,043.

In the above grip-lever because the pawlreleasing latch is arranged on the opposite edge to that receiving the applied han d-power it is much more convenient to handle when tightening the grip on the cable.

It will be observed that under the construction described the grip-jaws have their ends normally above the lower face of the cable when rasping the cable, It will also be observed that the lower part of the verticallymovable frame has tapered extremities, which bound the jaws at each end and lie normally above the lower face of the cable when the jaws grasp the cable.
