ELEVATOR.
SPECIFICATION forming part of Letters Patent No. 652,893, dated. July 3, 1900.
I Application filed February 14, 1900. Serial No. 5,128. (No model.)
To all whom it may concern: Be it known that I, FRANK E. HERDMAN, citizen of the United States, residing at Winnetka, county of Cook, andState of Illinois,
have invented a'new and useful Improvement. in Elevators, of which the following is a full,-
clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to that type of elevators wherein the lifting-cable is actuated by a drum about which the cable is wound. The
ordinary drum is provided with a spiral groove or a series of them, which accommodate the cable, and by the revolution of the drum the cable is wound or unwound, de-
pendent upon the direction in which the drum is turned. As the drum is stationary, this operation necessarily produces a side motion of the cable in the shaft, or means have to be provided to impart to the pulleys about which the cable passes a side motion corresponding to the side motion of the cable as it, is fed onto or off of the drum.
The object of the invention is to prevent of which will now be particularly described;
In the drawings, Figure 1 is a plan view of the drum and actuating mechanism. Fig. 2 is an end view of the same. Fig. 3 is a section on line 3 3 of Fig. 1. Fig. 4 is a section on line 4: at of Fig. 1.
A isthe supporting-framework for the drum and its immediate actuating mechanism.
B is a stationary shaft, screw-threaded toward one endand secured at each end to the frame.
. O is the drum, having the bearings c 0, one of which, a, is internally threaded and engages thescrew' end of the shaft. Both bearings are connected with the periphery o of the drum by the radial arms 0 0 D is a sleeve loose on one end of the shaft B.
E is a disk secured to or integral with the sleeve.
F is an internal gear secured to the disk.
vF is arpinion secured in bearings on the frame and meshing with the internal gear.
- f is the driving-shaft upon which the pinion is-mounted'. This driving-shaft has-mounted -upon1it or geared to it an electric motor, (not 'shown,) or it may be actuated by any desired means.
Projecting from the disk E and extending close to and parallel .with the periphery of the drum are the drum -actuating arms G, having bosses at their ends, within which are journaled rollers g, extending into longitudinal grooves g in the inner side of the drumperiphery. These rollers engage the side walls of the groove.
It will be understood that axial motion is imparted to the drum by the driving-shaft through the medium of pinion F, gear F, disk E, and arms G. It will also be understood that as the drum turns it will be fed upward along the screw, the rollers g moving relativelybackward within the groove g. The pitch of the screw coincides with the pitch of the spiral grooves on the drum-periphery, and it is obvious that as the drum rotates and feeds forward the unwinding cable will be maintained in the same line.
To'provide for automatically throwing the controlling mechanism to the center toward the end of travel of the drum in'either directionthat is, when the cable is nearly compl'etely unwound on the forward movement and nearly completely unwound on the backward movement-J have devised the following mechanism:
H is a ring splined upon the sleeve D, so as to rotate therewith and be capable of longitudinal movement thereupon.
I designates rods secured to ring H and extending longitudinally of the drum-shaft.
t' i are stops secured to the rods and in line IOO while the collar remains stationary; but any side motion of the ring is imparted to the collar.
K is a bell-crank lever pivoted upon the brackets 7t 7t, extending from the frame of the machine. The free ends of this lever are pivoted to the collar J at its upper and lower sides,respectivel y. The opposite ends of this lever are connected by a link K The other end of the link K is connected to an arm K which is secured to the operating-shaft Z. This operatin gshaf t is controlled by an y wellknown means from the car, a sheave M being shown in Fig. 1, which may be engaged by a control-cable extending through the car. The operating-shaft controls the motor by any wellknown means, a switch box M being shown in diagram in Fig. 1. No control mechanism is shown or described in detail, as the invention is applicable to any form of control mechanism. The shaft Z may represent or be connected with the control mechanism for brake apparatus instead of the main controller-shaft of the switch-box. As the drum nears the end of its forward travel the bearing 0 strikes the stops 6, drawing forward the rods I, ring II, and collar J, and thereby tilting the bell-crank K and through thelink K and arm K throwing the operating-shaft to its central position, and thereby stopping the motor or applying the brakes. Then the operating-shaft is thrown to the other side of the center to reverse the direction of travel of the drum, the stop 1" is in a position to be struck and moved by the drum-bearing 0, thereby through the same connecting mechanism again throwing the operating-shaft to its central position.
Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is--- 1. In an elevator, the combination, with the cable-wound drum and its actuating mechanism, of. means for imparting to the drum a movement parallel to its axis, the control mechanism, a stop or stops in line of travel of the drum, and connections between the stop or stops and the control mechanism,substantially as described.
