CABLE ATTACHMENT FOR ELEVATOR-CARS.

SPECIFICATION forming part of Letters Patent No. 611,416, dated September 27, 18981. Application filed April 30, 1897. $erial No. 634,548. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE H. REYNOLDS, a citizen of the United States, residing in Chicago, Cook county, Illinois, have inventeda certain new and Improved Cable Attachment for Elevator- Cars, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to the means by which the hoistingcables are attached to the elevator-car, and has for its object the provision of an anchor-block forming a socket or fasteningfora plurality of hoisting-cables arranged therein concentrically, such anchor-block being adj ustably secured to the car to compensate for the changes in the length of the cables. The purpose of arranging the hoistingcables in the manner described is to insure that they shall be brought over the overhead pulley in such a manner as to play in and out evenly and smoothly regardless of the angle at which such overhead pulley may be set with reference to the front of the car. In order to secure a result as perfect as possible, I also arrange the cable-sockets equidistant from each other.

Figure 1 is avertical view of my apparatus, showing the socket-casting and the crossbeams of the car in section. Fig. 2 is a side view of the same, and Fig. 3 is a plan view showing the arrangement of the sockets in the socket-casting. Fig. 4 shows the apparatus of Fig. 1 applied to an elevator-car, and Figs. 5 and 6 are views designed to show the arrangement of the cables running over overhead pulleys placed at different angles with the front of the elevator-well.

The socket casting 4 has the cables 5 se cured to it by the usual method, (indicated at 6.) Through the center of the casting,however, is a threaded hole 7, through which passes a threaded bolt or spindle 8, provided with nuts 9, 10, and 11 and the head 12. The

bolt 8 is put through the castings '13 from below and the nut 11 screwed downinto place. The nut and the socket-casting 4 are then screwed onto the outer end of the bolt 8 and the lock nut 9 followed into position, the

cables into proper If now it be desired to raise or lower the car With reference to the socket-casting 4-in other words, if it be desired to shorten the length of the hoisting-cables, for this is substantially the effect of raising the car-the lock-nut 10 is loosened and screwed downwardly, and the bolt 8 is screwed up to the position desired when the lock-nut 10 is again set. The manner in which the ends of the hoisting-cables 5 are arranged within the socket-casting 4 is clearly shown in Figs. 3,

5, and 6, this being Well adapted to guide the position to pass over the overhead sheaves.

Referring particularly to Figs. 5 and 6, it will be seen that in Fig. 5 the pulley stands at an angle approximately forty-five degrees with the horizontal plane, which is the plane of the front of the car, while in Fig. 6 the pulley 15 stands at a right angle with the front of the car, but that in both of these arrangements the cables 5 play in and out over the pulley equally well, being arranged concentrically around the center of the anchorblock 4.

Having thus described my invention, what I claim asnew, and desire to secure by Letters Patent, is-- 1. In an elevator the combination of a car; a plurality of hoisting-cables; and an anchorblock adjustably secured to said car and having the sockets of said cables arranged therein concentrically aboutthe center, substantially as described.

, 2. In an elevator the combination of a car; a plurality of hoisting-cables; and an anchorblock adj ustably secured to said car and havin g the sockets of said cables arranged therein concentrically about the center and equidistant from each other, substantially as described.
