OLIVER C. HAYWVARD, OF NEYV YORK, N. Y.

INDICATOR FOR ELEVATORS.

SPECIFICATION forming part of Letters Patent No. 396,159, dated January 15, 1889. Application filed Pebruaryl, 1888. Serial No. 262,629. (Nomodeh) T0 at whom it may concern:

Be it known that I, OLIVER O. HAYWARD, of the city, county, and State of New York, have invented a new and useful Improvement in Indicators for Elevators, of which the following is a full, clear, and exact description.

My invention relates to an improvement in elevator-indicators, and has for its object to provide a simple and economical attachment to elevator-shafts, whereby the approach of the elevator either from beloi or above will be indicated and the fact made known whether the ear is upon the ascent or descent, and wherein also the same fact is set forth upon the stoppage of the car at any floor.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a partial vertical section of an elevator-shaft havingmy invention applied. Fig. 2 is a side elevation of a section of the device. Fig. 3 is a perspective detail view; and Fig. 4. is a partial elevation of the car.

It is the prime object of the present invention to provide a simple and inexpensive indicator capable of use in connection with any shaft and car, which will be composed of few parts, and wherein the fact that the elevator is ascending or descending may be noted by prospective passengers approaching the elevator from any direction. To this end, within the shaft, or within a casing auxiliary to the shaft, the several indicators are pivoted, adapted for engagement with the car. In carrying out the invention I have illustrated the devices as pivoted in the elevator-shaft proper.

At a suitable distance above the flooring of each story, preferably in front of the elevator,

an aperture, (1, is made in the wall A of the shaft. Through each aperture (1 the vertical member I) of an angular indicating-block, B, is projected outward, the horizontal member Z1 being pivoted within the shaft to any suitable support and provided at the extremity with a friction-roller, b The said horizontal member at the pivotal point is provided with a transverse slot, If, for a purpose hereinafter set forth. I

At the extremity. of the vertical member I) a horizontal projection, Z)", is'attached or cast integral therewith, which,facingfrom the front of the elevator, has produced thereon the word Down or Up, according to the placement of the block. The same words are also produced upon the sides of the vertical member, in order that when the blocks are in position to indicate the movement of the car the words may be read from either the front or sides. V Vith the exception of the indicator block upon the upper floor, all are weighted at the lower outer end to keep the vertical member facing downward and in contact with. the outer face of the shaft, as illustrated in Figs. 1 and 2. The block upon the top floor has invariably the word Down produced thereon, the outer member being held normally in a vertical position, pointing upward, by the weighting of the inner arm or member. The upper block is also simply pivoted, the slot not being needed.

On the floors intervening the upper and lower stories a second angular block, D, is employed, fulcrumed upon the same pin with the blocks B. The end projection of the outer member (I of the said second block extends from one side only, in order that normally the said outer member of the block D may rest, pointing downward, essentially in contact and parallel with the block B and the shaft. The inner member d of the blocks D is shorter than the equivalent member of the blocks B, and is respectively connected to a lever, E, pivoted at one end to the inner wall of the shaft below the blocks, which lever is prox'ided at its other end with a friction roller adapted for engagement with the elevator-car, as illustrated in Fig. 1. The connection between the blocks D and the lever E is effected through a bar, H, slotted at each end, a pin being passed through the slots, respectively, into the inner member of the blocks and outer end of the lever beyond the fulcrum, as illustrated more clearly in Fig. 2. The outer member of the blocks D is weighted, and the lever at its outer under surface likewise, sufficiently to retain the latter, when idle, in a downwardly-inclined position. The elevator-car is provided with a strip,

II secured to the front or side, projecting a suitable distanee above and below the same, whieh strip is pin-posed to engage the levers and all the blocks exeept that upon the lower floor. This bloek, which is out of alignment with the others, is engageal by a separate and shorter strip, 71, secured to the upper portion of the ear and extending above the same. The object of this second strip is to release the lower block ahnost as soon as the elevator-ear has started.

In the event the shaft is so narrow that the blocks eannot be introduced without interfering with the door when open, a easingmay be eonstrueted outside the shaft and the shaft slotted to receive the inner members of the hloeks and the lever. It found desirable, the strips upon the ear ma be so placed, and likewise the blocks with relation to the strips, that the blocks will cease to indicate immediately upon the elevator starting from any tloor, or just after.

In operation, the ear being at the lower tioor and the inner member of the block I; in engagement with the short strip 74, the outer member otthebloek assn mes a horizontal posi tion, havin the word lip produeml thereon. Almost immediately upon the elevator leaving the lower floor the block I is released to assume its normal. position. In approaching the next story and before reaehing the same the upper end oi. the strip ll, (":oming in contact with the lever E, causes the outer member of the bloek I) to assume a ln'n'izontal post tion, which, having the word Up produeed thereon, indieates before the stoppage of the ear and after the car has stopped the direction in which it is moving or to move. In its further ascent the ear eomes in contact with the inner arm of the substantially duplicate bloek ll, upon which the word Down is produced; but the ear in its upward eourse does not move the intermediate bloelcs I to an indicating position, as the slot U therein allows sultieient movement ot the inner arm to permit the free passage of the ear without l l l l action of the said blocks. When the upper story is reaehed, the strip ll, coming in eontaet with the upper bloek It, causes the vertical member to assume a horizontal position indicating Down, Iieaving theupper lloor and gi'ling down, the car at the intermediztte floors, by means olfthe strip ll, is brought in eontaet with the several bloelcs .1), raising the outer members to a horizontal position indicating Down. The lever E does not act when the car is passing down, owing to the slots in the conneeting-bar ll, the said lever being intended to engage the ear for action upon its upward course. 7

llaving thus fully described my invention, I claim as new and desire to seeure by Letters Patent-- 1. In an indicator for elevators, the combination, with a vertical shal't, stages or lioors :nljaeent to said shaft, and the ear :nlapted to travel in the latter, oi angle-blocks which are pivoted above sueh stages or tloors,onemem her or arm thereol' projecting through the side of the shaft to engage with the ear, and the outer member oi? said block being ,n'ovided wit h an indicating-word and weighted to cause itto hang normally vertieal parallel to the side olf the shaft, as shown and described, to operate as specified.

In an indicator [or elevators, the combination, with the ear 1n'ovided with side projeetions, olf a double series of angle indicatingbloelcs, one series provided with africticm-roller upon the inner end adapted to engage the car, a leverconneetedwith the inner member of the seeond series engaging the ear and operating the block, and a horizontal projection int cgral with the outer member of each series of blocks, the said series having produced upon the l'aces ot' the respwtive outer members the words Down, and Up, sulr stantially as and for the purpose specified.
