8 is a detail elevation of a portion of one of the latch mechanisms. And Fig. 9 is a dctail plan viewof one of the switches.

Similar indices denote like parts throughout the several views.

In order that the construction and the operation of-iny invention may be more fully understood and appreciated I will now take up a detail description thereof in which I will set forth the invention as briefly and as comprehensivelyas I may.

My present invent-ion is intended to be used in connection with an elevator-car D arranged to travel up-and-down through the shaft which is formed by openings therefor through a. plurality of floors, A, B, C, or 9:, 2, 2 and 2 for instance, although there may be any number of doors between which the car operates up and down.

It is to be understood that my invention is especially adapted to operate on the intermediate gates which normally close the openings from each floor to the elevator shaft, as shown.

Letters .l) and F. denote the gates which close. the opening ron'i the respective floors. B and O to the elevator-shatt, as shown in Figs. 1 and 3. As shown in Fig. 2 a. fourth door, if is added; and in Figs. 1 and 3 a gate E is provided for the first floor. Saidgates are mounted to slide up and down in. suitable guideways formed in the sides of the openings in any well known manner.

he elevatoncar isj provided with the. usual stationary standards in the center at each side thereof, as the standardd for in-' stance, which are arranged to guide the car up and down controlled by suitable guides which engage with the track carried by the. posts G for instance. The car D is adapted broadly speaking, is to provide a construction combining a minimum of mechanical elements into an electri ally operable, open at will, elevator-gate mechanism, which will be strong and durable in construction, simple to eti ectuatc, positive in action, and whiclrcanbc manutactured and sold at a comparatively low price.

A more specific object is to provide a mechanical construction which will contain only the indispensable requisites for an electrically operable, open at will, elevator gate niechanisn'i whereby the gates which guard the various hatchways of the elcvator-shatt will remain closed, regardless of the number oi? times the elevator-car passes up and down until such time as shall be selected by the operator of the car, and then only providing the. door of the. car isapproximately even with one ot. the. [tours of the lniilding in which the eleraton -ar is located.

Other objects and particular advantages ol my invention will be brought out and made clear in the course oi the 'l ollowingl specification, and that which is new and useful will be emphasized in the appended I claims which terminate this tlQStIlPlltlll. l

Ono manner for the construction of my im'ontion, and that which in practice I have found to be the most. practical and economically otlicient, is shown in the awoinpanyingi; tour sheets of drawings, in which-- Figure 1 shows a perspective view of the arrangement of my invention, as applied to a building having three tloors and one intermediate gate to which the operating mechanism applied, showing the car at the bottom lloor. Fig. is a perspective view of my invention as applied to a building having four floors and two intermediate to be raised and lowered in any well known manner, as by the cable H by which it may be suspended and lifted. The pcwer for operating the elevator-car is. controlled by the small cable I, which operates at the base around pulley J the upper portion at which is not shown, operates over a similar pulley one of which pulleys may act: as the power controller in the usual manner.

Numerals l and 2 denote each a rod which are of the same length and which extend from near the bottom to near the top of the elevator-shaft, the same being carried by l l l l l l and adapted to slide up and down in suitable brackets 3, which latter are secured to theface of the Wall K, there being apertures formed through said brackets in whi h the rods may slide up and down, there also being a space between the side of the car I) and the wall K for said rods to be located without interference, as well as other de H v es which will hereinafter be fullydescil'bed. The lower ends of the rods 1 and 2 are connected rigidly together by the plate 4, and their upper ends are likewise connected by .the plates 5 and 5 which are spaced apart for the purpose hereinafter appearing.

Secured to the plates 5 and 5, centrally of the rods hand 2, isthe rack-bar (3. At.- tached to the upper end of the rack-bar (5 is the rope 7, which extends directly up and then over the pulley 8 and then back to any convenient point and then over a pulley 9, and then down to the count'erba-lanw ing weight 10. The specific gravity ot' weight 10 is such as to normally raise the rods 1 and 2 upward to their highest point of elevation and also the parts thereto attached.

Letter M denotes an electric motor, ot any convenient construction, adapted to revolve the shaft 11, on which latter is secured the pulley N, the outer end of the shaft 11 being supported by the bracket 11 which is socured to the wall K. Also secured to the wall K is the bracket 12 in which is mounted the pulley 13.

Numeral 14 denotes an endless hand. or sprocket-chain which operates over pulleys or sprockets N and 13 substantially as shown.

Numeral 15 denotes a rope, or the like, one end of which is secured in the center ol plate 4 (Fig. 3) extending downward, with its lower end secured to the band or chain l-l by means ol' the finger 16, as indicated.

'From the above it isv apparent that. i l the motor be opt-rated in one direction that the hand 14 will carry the finger 1G dmvnward. moving the rope l5 dowmvard, and also pulling the rods 1 and 2 downward and thereby raising the weight l After the rods 1 and 2 have been pulled down lo their limit it will be s en that it the power he cut ofi from the motor that the weight 10 will return the rods 1 and 2 to their upward position. In order that the last named movement of the chain 17 may be more positire, that is to cause the motor to coast backward, I provide the weight 0 which is suspended by the cord P, which latter passes over pulley Q. and then down and is secured to the opposite side of the band 1% from that of said finger 16. The pulley Q is carried by the bracket R, the latter being seeuredto the face; of the wall K. The weight 0 causes the motor M to operate idle and rev'ersely when the electric current is cut off.

A latching device is located at each intermediate floor, all being made identical with "ach other, and all are carried by and are slid-able up and down on the reds l and 2, certain details of which are shown in Figs. 7 and 8. All of said latching devices being alike I will describe but one in detail and refer to'like parts of the others by similar indices.

Numeral 2O denotes a yoke extending across and having two apertures in which may neatly slide the two rods 1 and 2. Formed integral with the yoke 20 and extending down centrally therefrom is the stem 21.

Numeral 22 denotes a plate which has a downwardly extending stem 23 which is pivoted to the lower portion of the stem 21 in such manner that the plate 22 may swing out a limited distance (as in Fig. 1) away from the rods 1 and 2. Two slots c and f are "formed in the rear edge of the plate 22 to receive therein the respective rods 1 and 2. The plate 22 normally swings away by gravity so that the said rods will not be in said slots. Mounted in the frontedge of plate 22 and extending out centrally thereof" is the roller S, which is for the purpose hereinafter set t'orth. Secured to each of the latching devices is a rope or the like each ol which has its other end secured to one oi. the gates, as for instance rope 24 which extends up to the ceiling above that floor, passing over pulleys Q5 and 26 and from the latter directly down to the center of the gate E to which it is attached, as shown in Figs. 1, 2 and 3. Tn like manner each of the other intermediate gates is connected by its rope 2 1- to a latching device, said ropes extending over like pulleys 25 and 26. Tn order that. the rope it may have a straight pull upon its latching device it is evident that an auxiliary pulley 27 may he used.

Numeral 28 denotes a cam which is secured to the edge ou the. car and extends above and below the platform thereof and it. is adapted t engage the rollers S, as the car moves up and down the shaft, thereby pressing the plate, 22 back and causing the. rods and i to enter the slots 0 and f, as slnrwn at th right in Fig. 7.

At: properly predetermined intervals there are nuts or buttons secured on the rods 1 and 2, as for instance the nuts 0 and (I, respectively, there being a pair of said nuts for each door, the same being adapted to engage in sockets g and h which are formed in the upper face of the plate shown in Figs. 7' and 8 which are located around the inner portions of the respective slots 1 and Said engagements of course taking: place when the roller S is in engagement with the cam QSQat other times the plate 22 is swung out so that the nuts can not engae e in the slots thereof. As the cam 28 is carried by the edge of the car it apparent that the roller S must be so located that its contact with the cam will occur only when the floor of the car is even (or nearly so) with "one of the intermediate floors. It

0 should be noticed thatv only one of said 6*positi'0n in Fig for convcnienco in drawlcywhich is near the power rollers S can be in engagement with the cam 28 at any one time regardless ot'the number of floors through which the car is adapted to travel.

Located near the ceiling of the upper floor, in the locality of the rack-bar (3, is the locking mechanism, shown in detail in Figs. 4:, 5 and 6. the same being shown as broken away and. locatedbelow its proper ing. Saidlocking inechanisi'n operates in connection with the rack-bar 6, and it comprises a pair of brackets 30 and 31 secured to the wall K, slightly to the right of the barsl and Slidahly i'nountcd to operate "vertically-in the brat'ikets 30 and 31 isthe bar 32. Attached to the upper end of bar 32 is the rope 33 which extends up over pulley 34, then across near the ceiling to puh 7 controlling cabled) and then down, being secured to cable I at the point whereby the bar 32 will he moved up or down when ever the elevator is started or stopped, which is initiated by the operation oi cable l a slight distance.

Secured to the bar 3:2 and spaced apart, and located between l'irat-ltets 3 and Ill, arc the two clips 36 and J-J. arried by and connecting; the clips ill; and. '57 are the twin spaced apart, cannbars or guides Ella and Pitt which are parallel with each other except at their upper and lower ends where they flare apart. The upper third and the lower third oi said bars are oll'set in th same direction (inward) whercl'iy the central third thereof s'ofi'set (outward), that. is toward the wall K, with relation to the other two-thirds, all substantially as shown in Fig. 4.

Secured to the wall l\' is the braeit'et 40 to which is pivoted the upwardly extending arm 4i, which latter carries at its upper end the horizontal shaft 42. livotod on shat-t. 42, in alinement with the rack-=bar ti, is the 5, dog 4-3, the point thereof being adapted to engage the teeth of the rack-bar 6, the other vend of the (log being weighted, as indicated in Fig. 4. Also carried on shaft 42 is the roller l4 whose diameter is slightly less than is the width of the space between the cam-bars 35 and 3t), between which it operates the bar 2323 is mm ed up or down.

From the abore it will be apparent that il the right -hand portion of cable I be pulled down to start the car down, for instance, that the rope 3-) will he pulled in such manner as to raise the bar 32, carrying the can1- bars 39 and 251) upward, which will cause the roller i t to be located in the lower portion of the space between the cam-bars, thereby moving the dog away from the position where it might contact with the rackbar (3. It will be apparent that it the lefthand portion of the cable I be pulled down, to start the car up, for instance, that the rope 33 will be raised. allowing the bar 32, carrying the cam-bars to more downward, which will cause the roller 44 to be located in the upper portion of the space between the canrbars, thereby moving the dog away from position to contact with theraclt-hai."

6, the same as when it was in the lower space. And it. is also appa'rei'it that when the cable I is in normal position, that is the pcsition causing the car to be at rest, that it will. cause the roller 4st to. be located in the central portion of the space between the cam-bars, thcrol'iy causing the dog to be in pos t ii to engage or to be engaged by the rack-bar 6, that when the "aclt-bar is moved down to the position to be engaged by the dog, as that shown in Fig. 4-.

Secured to the wall. K. opposite each intcrmediatc liooi'. as the floor B for instai'ice, is a pair of contacts and 5i; and in alinement therewith but secured on the edgi'e oi the car ll are the two shoes 52 and 55 which are adapted to contact with the respective contacts ea h time the ca is even with that Secured in the standard r1. within reach of the operator of the car, is the pushbulton 45. l lxtcnding' troin each of the pole"- ot the 'nish-button is a wire. as the wires :34- and 553 shown in Fig. l. The oth r ends oi said wires are connected to the respective shoes 52 and 53.

l lxtcnding in from the source oi supply is the service wire 56 which is atta hed to contact. 51, and service wire 57: extends in and is attar-ln l to one pol ol the motor hi FIX-- tending from the other pole of the motor is the wire whos other end is attached to the switch shown in detail in Fig. l). Said switch is attached to the jamb or to the wall K, and it consists essentially ot'the base 5.) having a forked pole (it) in which may engage the blade til, the said blade being normally retained in engagement with the pole 60 by the spring (32, said blade being trical connection. Said wire '58 is connected to the pole (it). A wire (33 extends from the spring 62 to the contact 50. Secured to the upper right-hand corner of the gate 1), for instance. is a linger (it which when the gate 1') is raised to a certain height will push the blade tit cut of contact with the pole (it) against the resiliency of spring (32. In case there are other intermediate tloors then a pair of (Otittllir- 50 and 51 are provided located opposite to each tioor as shown in the above instance. the same being treated in position to he impinged by the shoes :32 and 53. and the wire of) ina he extended up to the contact corre poznliug to c ntact 51 and located thercahow: while in like manner wire (it; ma he extent ted to a switch for that floor and then to the other contact next above contact 30. and so on regardless of the number of lloors in the building.

ln Fig. 2 the lower tloor shown is denoted by indice the next door above by 2". the next by 2", and the upper floor by 2", the other parts being substantially the same as in the other views.

'1. he operation of my invention may be as follows: The car l) is intended to operate up I and down in the shaft. passing the various tloors but without moving any of the intermediate gates, except at the will of the operator. If the car be located at floor A then if the left-hand portion of the cable I he pulled down the car will start up, and it the car be up and the right-haud portion of cable I be pulled down then the car will start down, all of which is well known and is not part of this invention. Now suppose that the car 1) in passing up or down should stop at either intermediate tloor, as for instance t'loor B,the gate E of course will still remain closed even after thc car stops. But should the operator now pitess the button 45 then an electric current will be establishedz-passing through wire 56 to contact 51, then to the shoe 53, then up wire 55, through button 45, then down the wire 54 to the shoe 52, then to contact 50, from the latter it will pass through the wire (33 to the spring 62, then through the blade 61 to the pole (50, then through the wire 58 to the motor M, the other poleof the motor being supplied by the wire 57, thereby completing the circuit. As soon as said circuit is completed the current will start the motor to operate thereby turning the band 14- and pulling the rods 1 and 2 downward endwise. The car being located 'at floor B it is-cvident that; the cam 28 pressing out. on the roller S will cause the slots n and f to stride the respective rods 1 and 2, whereby as the rods are moved down as just stated the nuts on said rods will engage the plate 22 and thereby carry said plate 22 downward therewith. The rope 24 is secured to the yolte 20, which latter is rigidly connected to said plate 22, by which it is evident that rope Qt at that floor will be pulled with the rods 1 and 2, thereby'raising the gate E. It should be noticed at this point that only one gate can be raised at one time, as the car must be opposite a floor in order that the cam 28 may press one of the plates 22 into position to be engaged by the nuts on the rods l and 2. Continuing the operation: It-is evident that when the gate raises to a point where the linger (3 t presses the blade 61 out of cantact with the pole-( 0 that at that tin .he current will be broken at the latter point. and consequently the motor will stop, and therefore the gate will stop and it will he held in its elevated position until the car is started to move up or down, as will hereinat'ter be described.

During the time certain of the operations just described are taking place another important operation is in process: As the cable I is moved to start the car the rope 33 connccted thereto will raise or lower the bar 32, thereby moving the dog 43 out of alinement with the rack 6. but as the cable I is moved to normal position again, to stop the car. at lloor B, for instance, the dog will he moved to operative or engaging position, that .midway of the cam-bars 38-39, as in Fig. 4. Now as the bars 1 and 2 are moved downward, as stated, it is evident: that. the rack 6 will be moved down also. the (log t3 gliding idly over the notches of the rack, but when the circuit is broken, as stated, and the'eurrent is cut oil from the motor then the weight 10 will tend to draw the rods 1 and 2 back to their first position, that is to their upper limit of movement, but at this time the dog 43 will engage one of the notches of the rack (as in Fig. 4) thereby holding the rack 6 and consequently holding the rods 1 and Q at their lowercd position. thereby retaining the gate I) raised, holding it raised as long as the car remains atthat tloor. -However should the operator now desire to move his car to another floor then the first operation will be to move the cable. I, to the proper position, to start the car, which of course will move the cam-bars 3839 up or down which manifestly will pull the dog away from connection with the rack (i, which will allow the weight 10 to pull the rack (l and the. bars 1 and 2 upward which will of course allow the gate E to close by gravity.

From the above it is evident that l pro-- vide an open at will elevator gate that is adapted to be opened only when the car is opposite that floor, all gates remaining closed at all times except when the car is opposite a certain floor at, which time the the operator.
