DAVID D. NOLLEY, OF VILSON, NORTH CAROLINA, ASSIGNOR OF ONE-IIALF TO AMOS J. HINES, OF SAME PLACE.

CABLE-CAR GRIP.

SPECIFICATION forming part of Letters Patent No. 475,143, dated May 17, 1892.

Application filed December 22, 1891. Serial No.4l5,887. (No model.)

To all whom it may concern:

Be it known that I, DAVID D. NOLLEY, of Wilson, in the county of Wilson and State of North Carolina, have invented certain new and useful Improvements in Cable-Oar Grips; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specication. A v

My invention relates to improvements in cable-car grips; and it consists vin the construction, combination, and arrangement of parts, 4which will be fully described hereinafter, and particularly referred to in the claims.

The object of my invention is to provide a grip for the lower cable of crossing lines, which is so constructed that it automatically allows the crossing upper cable to pass through the grip, while at the same time the grip holds on to the lower cable and to the car, whereby power is transmitted to the car from the lower cable while it is automatically allowing the cross-cable to pass throughpit.

In the drawings, Figure 1 is a vertical section takenthrough the car longitudinally at one side of the grip, as shown by dotted line cc o3 in Fig. 3, one side of the standard being broken away to show the hooks. Fig. 2 is a similar view taken through the car on the opposite side of the grip, as shown by dotted line 'y y, Fig. 3. Fig. 3 isa plan view, a portion of the bottom of the car being broken away. Fig. 4 is an enlarged view of the grip, showing the specific form of the automatic hooks. y

A indicates the bottom of a car which is made of any desired size and style.

` Secured to the under side of the bottom of the car is a circular ring or disk B, which is supported a suitable distance therefrom to receive a disk O between it and the under side of the car. Extending down from this Kdisk C and either secured rigidly thereto or The lower edge of this standard hasv formed therein a series of vertical openings or sockets F, near one end of which are journaled the rollers Gr.

The grip proper consists of a longitudinal plate H, which is provided with the two rollers I, journaled upon one side thereof, which receives the cable J of the lower line upon their upper sides. Above these rollers a suitable distance and extending outward from the side of the plate H, preferably about midway between the two rollers or wheels I, is a bracket K, which is provided with a vertical screw-threaded opening to receive a clampingscrew L. The lower end of this clampingscrew is swiveled in the center of a plate H which has its ends extending over the wheels I and above the cable J. In this manner, when the plate I-I is forced down by turning the clamping-screw, it grips Lthe cable between it and the wheels, thus securing'the car to the cable, which is carried thereby in the ordinary manner. l

The clamping-screw is operated by means of a vertical operating-rod N, which passes directly through the center of theplate C, for a purpose to be fully described hereinafter. This rod N is held up above the cross- 'cable O by means of a suitable spring I, and

is provided at its lower end with an angular socket to receive the upper angular end of the clamping-screw. In order to operate the clamping-screw, the rod N is pushed down and then given a turn to force the clampingscrew and the plate carried thereby down to grip the cable J. The pitch of the thread on the clamping-screw will be great enough to force the plate down by giving it a partial turn, as will be understood.

Pivoted to the opposite side of the plate H from the wheels are a series of levers Q, which are provided at their upper ends with hooks that extend into the sockets F and catch over the rollers G. These levers are preferably inclined away from the direction the car is traveling, so that rollers R, which extend outward from their lower ends, will more easily pass up the incline S of a projection T, that IOO until the cross-cable O has passed the hook.-

' As soon as the cross-cable has passed the hook the roller at the lower end of the lever drops oif the projection T, and the lever is forced: up into position by means of the springs V, which engage therewithin any suitable manner. In this way each hooked lever is turned and automatically detached from the carstandard and then instantly thrown back to position by i-ts spring after thel cross-eable has passed it. The hooked levers are each provided with rearward extensions or shoul-y ders d,.which overlap the sockets .F and engage` therewith atthe point b to prevent back vmovement of the plate H, and as forward movement of the plate is prevented bythe upper end of the hook engaging the upper endof the socket it will be seen that the said plate H is iirmly held to the stand-ard against movement in either direction.

, From the' above description it will be seen that only one hookV isoperated at a time and that'two are in engagement while one is disengaged to allow the cross-cable to pass, thus keeping the car in connection with the cable of itsv line, while-it is at the same time-passing a-cross-upper cable. By means of this construction. the car is being drawn-by the cable f as wellI whenl passing a crossfcable as when not, thus avoiding the necessity ofraising the grip to letthe car pass by its momentuml in the usual manner, which is very objectionable. Theends of the standard andY of the plate H are cut at an angle or inclined, as shown,in order to catch and guide the crossk cablevbetwe'en the two.

tion to operate when the car is runn-ing in p Whilel here show only three levers,.it will be readily conceived that as many may be used as desired without departing from` the spiritof my invention.

By means of the ring B and plate C the grip is readily turned around when the car 50' reaches the end of the line, so that it willoperate in the opposite direction. yThe grip is turned around by means of a vertical rod d, which has its lower end securedto they plate C and extending up through a semicircular slot e. By turning this rod from one endof the semicircular slotl tothe other the' standard and the grip are turned in the reverse position whereby the grip is revolved or rotated to operate in the opposite direction, it will be understood that this is not a necessary part of my invention, for the grip can be made stationary when the cars are turned around at the end of the line. If the cars are not turned' around, as is ordinarily the case, then" the grip is given a rotation, as described.

Having thus described my invention, what yI claim, and desire to secure by Letters Patent, iS-

l. A grip comprising a standard, a plate car- `Aryingr a grip,y hooked levers pivoted between their ends forconnecting the plate and standard, and avmeans at the cross-cable which operates the hooks, substantially as described.
