The invention relates particularly to anequipment for eleratorsnnerein the doors of the elevator shaft are controlled by the car.

The invention to provide as its principal ohjeet a means whereby the doors opening into the elevttor shaft from various floors may he seemed a ganrstopening except when the 'Hoor of the Car level 'with any of the floors on to which the doors open.

Another object of the invention is the provision of means to prevent the operation of the car atte "a door has been opened as a result of bringing the car to the level of any partieular lioor.

Still another object of the invention is the provision of an electrically operated app-aratus conjoined With the car and with the elevator shaft doors of the several floors of a 7mlildinzgg', 'whereby the principal objects of the invention are contained.

Still another ohjeet of the invention is to provide an equipment o'l thisi, charaotz. which is simple in construction, which is easily installed and which is cheap and may, therefore, he employed at a small cost.

Other and further objects will appear as the invention is set `forth in detail in the aecompanying; description.

To the exact construction herein shown and described, the invention is not to loe restricted. The actual practical application of this equipment may show certain desir-i able changes or alterations to be advisable and these the right is claimed to make. in so far as they may tie compatible with the spirit of the subjoined claims.

Referring to the drawings, there vis shown an elevator shaft 1 communicating' with the several ioors 2 of a building. Each floor is provided with a. door 3 that communicates with the elevator. shaft, these doors beineT slidaoly supported in trout ot the door opening on a suitable track from which they are swung by the hangers t. The doors Sere hung in the elevator shaft and are of slightly larger dimensions than the door openings which are indicated by dotted lines in Fifi. l. lilith particular reference lto l, the doors are intended to loe opened by moving them to the lett and the equipment comprising apart oi' this invention and which is designed to be atta-.cheri to the doors earried on the front ends 'thereof which. as shown in L is ou the right.

The surrounding frame 5 on Aeeeh door opening provided with a tripping; inem ber 6 met" ed near the .upper right hand corner7 it being; assumed that the equipment as it is beingdescrilied ifbeing' viewed from vithin the elevator shaet.- This tripping member 6 is o'f the shape shown in Figs. l and Q and is fixed pivotaliy to the frame 5 by means of u su' ialole rivet or pin 7 WlfiioA passes through it at the lett hand end and enters the door frame. The tripping memloer 6 is designed to lie horizontally andit iS provided with a diagonal edge 8 and asyei`- tieal edge 9 at the right hand end., this right hand end being in Aclose proximity to the right hand side of the frame 5. A pin 14 is `fixed in the trame 5 andv the diagonal edge S rests on this pin, thus holding the tripping @senese gaged by the 1i-shaped end of the paivl 35i the latter being slidable through a guide 36 carried `within. tl:V car. A. solenoid l? is also carriedniithin the car and this solenoid is proifided with projecting@T erin 3S on which there is fulcrulned a leer 3f) which at one end eli'ects pivotal connection with the bottoni end ot thepawl 35, the end of tne lever belngprorided with an elongated hole to permit its oscillatory movement at the saine time .that tie paal is moving vertically.

The solenoid 37 is provided with the usual iluno'er l0 and the end of this lunUer is li. b D

connected to the adjacent end of the lever by a. linlr 4l. "li-Then the solenoid 37 is deenergizedv` the longer erin of the lever trips by gravity against the stop 42 thus bringing the pawl 35 out. of engagement with the notch and also raising the plunger 40. When. the solenoid 3T is en: ergized., it draws in the plunger Ll@ and thus operates to raise the pawl 35 so that it may engage the notch 34.

To prcnfide the necessary current for the equipment any s hable source of electrical suppl;7 is employed and a conducting Wire el leads `troni one terminal of this supply and extends throughout the length oi the elevator shaft l. Taps are taken oir the conductor lll adjacei'it each floor through which the shaft. 1 passes and these taps are connected one to each of the contact plates 2S. The conductor i6 is led *from the other source ot electrical supply and connects with the cer 21 on the bottom thereof in the same Way that the light and bell conductors connect with the car. means a conductor 47, the conduct-or 4G is connected with the terminal of the solenoid 37 and the lother terminal of this solenoid connects by means of a conductor e8 with the stud 22.

Let it be assumed that an elevator equipnient provided with the present invention is in use and that all the doors of the elevator shaft are closed and that all the attendant parts are in their normal positions. Let it be further assumed that the car 2l 1's between two floors and that the roller 25 has just passed under a. guide 3l. lThis roller 25 will then haresuch a position relative to the car and to the shaft. to bringr the Contact arm 26 in the position to have its bifurcated end con ising the spring clips 2? enter between the pla "When this arm res and 25 'thus enters between the 'two plates, the s designed to be level With anding onto which the attendant door 3 oi th t landing; opens.

insure a. `tirni contact between the arm and the plate 29) an electric circuit Will be es tablished from the source of electrical supply #i3 over the conductor nl, the solenoid itl, the conductor '-l-, the plate 29, the arrn 2G. the bolt 2l, the arm 23, the bolt 22, the conductor lththc solenoid 3?, the conductor l? and conductor lo back to the source of supply i3. rl`hc solenoid 16 is thus energized and raises its plunger l? leaving the door 3 tree to be opened. But the solenoidv? is also energized at this time and, the car hai'- ing been brought to a stop by the bringing ot' the lever 32 to a vertical position, the solenoid l? by operating the lever 39 eects the locking of this lever. The particular door 3 concerned may, therefore, be opened but the car 2l may not be moved because oi' the locking of the control lever 32. As the door is opened the upper end of the lever l contacts with the diagonal edge of the tripping lneniber 6 the door is thus permitted to slide back on its hangers el. rhe car having discharged its load, the door is closed but just before the completion of the closing operation the upper end of the lever l() is brought into contact with the vertical edge of the triprlhe movement or" the door then shifts this lever l0 on .its pivot ll and throws the lower end of the lever out beyond the front edge of the doorl and brings its inclined portion l into Contact with the inncr circular edge ot' the roller 25. The continued movement ot' this lower portion l0 by means of this inclined portion l5 opcrates to Withdraw the Contact arin Q6 from fric-tional engagement between the contact plates Q9, and 30.. since the arni 23 which carries the roller Q5 and the arm 26 is permitted to be moved pivotallj7 against the friction of the washer The circuit. which had previously obtained is broken b v the Withdrawal or" the contact arm QG from the Contact with the plate Q9. Therefore, the two solenoids concerned arc deinergized, the one dropping` its plunger and locking the door, the other permitting its plunger to be raised b v the droppingof the lever 39. The operation of the lever l0 results in moving the arm 9.3 and the other parts associated therewith. into a position Where the contact arm 2S Will not he able to engage the contact plates 29 and 3() ol the next door at which itis desired to stop. Vlie object of the guides 3l is to reestablish the condition of aliairs that existed before the operation ofthe lever l0 when the car is in the vicinitlv o't` the nent floor n'here it is desired to stop, the tguides 3l operate to shift the roller 25 andthe arm 26 back into a. position Where the said arm may be enabled to engage the contact plates 29 and 30.
