ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 615,080, dated November 29, 1898.

Application filed February 17, 1898. Renewed November 6, 1898. Serial No. 695,627. (No model.)

To all whom it may concern.-

Be it known that I, HENRY I. LURYE, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Elevators, of which the following is a specification.

By means of this invention danger of falling is avoided and derangement is signaled, as set forth in the following specification and claims and illustrated in the annexed drawings, in which Figure 1 is a side elevation of an elevator.

Fig. 2 is a section along line a: m, Fig. 1. Fig. 3 shows cables running about a drum. Fig.

4 is a spring tension device. Fig. 5 is a face View of Fig. 4, partly in section. Fig. 6 is a detail view of a leverarm. Fig. 7 shows an electric contact-maker out of action. Fig. 8 shows the same in action or making contact. Fig. 9 is an edge View of Fig. 7. Fig. 10 is a detail view of parts of the contact-maker. Fig. 11 shows a clutch for the safety-cable.

The elevator body or cage may be of any suitable construction for freight or passengers and is shown with its floor at 1 and a roof or cross-beam at 2, Fig. 1. The elevator runs along rails 3 of suitable construction, sometimes being toothed or made as racks; but such rails can be left plain, if seen fit. Clutches or jaws 4, suitably gripping the rails to prevent fall, can be applied to act in case of danger.

The elevator 1 is actuated or held by one or more cables 5, running over pulley 6 to drum 7, actuated by suitable appliance or power. In addition to the actuating-cable 5 a safety-cable 8 runs about pulley 6 and is also wound or moved by drum 7. This cable 8 connects with a lever 9 10, fulcrumed at 11 and suitably over-Weighted or exposed The arm 12 is connected by ates the connections 16 and 17 to rock shafts 1S and bring clutches 4 into action.

The safety-cable S is arranged to normally hold lever 9 1O horizontal or clear of arms 12 and 13. In case of accident, suppose the cable 8 to be broken. Then the lever 9 lOis freed and strikes its arm 10 against arm 12 to actuate the latter and bring the clutches into action. Again, suppose the cable 8 is not broken, but held or strained so as to swing lever 9 10 to bring arm 10 against arm 13. This arm 13 being then swung, the gears transmit the motion to arm 12 to again cause clutching or stoppage of the elevator 1.

Supposing the elevator is descending too rapidly, the cable 8 is held or stopped by jaws or clamp 20, Fig. 3, actuated by governor 21, driven by pulleys 22 and 23 and belt 24. The governor 21, when rotated with excessive Velocity, causes rod 25 to be moved longitudinally, so that stud 26, Fig. 11, on this rod, traveling along the inclined slots 27 on jaws 20, causes the latter to clutch or hold the cable 8. The cable 8 being held by holder 20 while the elevator 1 continues to descend, the lever 9 10 is swung to actuate arm 13, as noted.

The cable 8 is suitably connected to leverarm 9, as seen in Fig. 6, where the cable is guided through eye 28 to the adjustable fastening or screw-eye 29.

The stud 11, Fig. 4, forming the fulcrum of lever 9 10, is secured to beam 2, and to such stud is fixed or secured a ratchet-disk 30, engaged by spring-pawls 31 on collar 32, having handle 33 and adjustable or rotary about stud 11. This collar 32 has connected thereto at 34 an end of spring 35, also connected at 36 to the sleeve 37, rotary on stud 11. This sleeve 37 has secured thereto or is formed or cast with the lever 9 10. By suitably rotating or adjusting the collar 32 the spring can be tightened, as required for securing the proper function of lever 9 10. A spring 35 is preferable to a weight, since during the fall of the elevator the effect of any overweight on the lever might be interfered with or neutralized.

In case the lever-arm 9 swings out of horizontal or inactive position it closes one or another of the circuit- makers 38 and 38. From closer 38 runs wire 39 to wire 40 to alarm ICO mechanism All, whence wire 42 runs to battery 43, having wire 44; returning to contactmaker 38. The wires 39' and 4:4 similarly run from and to contact-maker38. These contact-makers are in reach or in the path of the lever-arm 9.

As seen in Figs. 7 to 10, the contact-maker or plate 38 is pivoted at 45 and the spring i6 normally tends to hold the same clear, as seen in Figs. 7and 10. As the lever-arm 9 swings and strikes the contact-maker 38 the latter is swung to contact with the terminals or springs 4-7, Fig. 8, so as to close the circuit for the alarm.

The alarm-circuit is kept in action indefinitely by a spring or serrated catch 48, Fig. 8, which looks the contact-maker 38 in action against return or clearance by spring 40 until the catch 48 is withdrawn by hand. The circuit-actuatin g alarm 41 announces that leverarm 9 has been in motion. For example, in case the supporting-cables 5 should have been stretched the alarm announces such stretch or weakening in time to enable required repairs to be made in advance of a break or fall.

The jaws 20 can be given a parallel motion by having the fixed pin 49, Fig. 11, passed through the slotted parts 50 of the jaws, these slots 50 being similar to slots 27, Fig. 11. As the rod 25 moves stud 26 toward stud 49 to close the jaws the jaws are also moved along stud 49 to cause the slotted parts 50 as well as 27 to close the jaws. Each jaw 20 is practically formed by several serrated plates, and by placing the teeth of these plates out of alinement with one another a secure grip of cable 8 is assured.

The contact-maker can of course be applied elsewhere than 011 an elevator.-

\Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination with an elevator-cab and its guide-rails, of an actuating-cable and asafetycable, a drum common to both of said cables, a lever pivoted to the cab and having a connection at one end with the safety-cable, a pair of arms moving in unison and placed within reach of the lever upon opposite sides thereof, and clutches mounted upon the cab and arranged to engage the said guide-rails, said clutches being actuated by the movement of the arms.

2. An elevator, an actuating-cable and a safety-cable, combined with a leverconnected to the safety-cable, arms geared to one another and placed within reach of the lever, clutch-shafts geared to one another and one of which is connected to one of the arms, and clutches upon said shafts, substantially as described.

3.
