ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 515,225, dated February 20, 1894.

Application filed January 3, 1893.

To all whom it may concern.-

Be it known that we, EDGAR W. HOUSER and CLARENCE O. DECKER, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Elevators, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

Our invention relates to improvements in elevators of the particular class set forth in the Patent No. 458,627, issued September 1, 1891, to E. \V. Houser, and has for its object the production of a device for opening and closing the elevator. shaft doors or guards as the car moves up and down, which is extremely simple in construction, practical and effective in operation, and occupies but a minimum amount of space so as to enable it to be placed in elevator shafts in which there is but little distance between the car and the wall of the shaft; and to this end the invention consists, essentially, in hinged elevator shaft doors or guards, a car, a support or guide at the side of the car, a lever having one end hinged to the doorat a point between the extremities thereof, an actuating lever having one end arranged normallyin the path of the car, a link having its central portion hinged to the opposite end of the actuating lever and having one end hinged to the door lever at a point between the extremities thereof and the other end hinged to said support or guide, and a second link having one end hinged to the outer end of the door lever and the other end hinged to the actuating lever.

The invention consists furthermore in the detail construction and arrangement of the parts, all as hereinafter more particularly described and pointed out in the claims.

In describing this invention, reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figure 1 is an elevation of an elevator car, a portion of two floors of a building shown as above and below the elevator car, and as provided with elevator shaft doors or guards, supports or guides for the elevator car, and

our improved invention illustrated as oper- Serial No. 456,977. (No model.)

atively secured to said doors and supports or guides. Fig. 2 is an enlarged elevation of a detached portion of one of the supports or guides, one of the elevator shaft doors or guards and ourdooroperating mechanism connected to said parts for opening and closing the door. Fig. 3 is an edge view of the detached shaft door operating mechanism shown at Fig. 2 and its detached plates secured to the door and to the corresponding guide or support for the car. Fig. 4 is an enlarged horizontal sectional view, taken on line et 4, Fig. 3, and Figs. 5 and 6 are enlarged vertical sectional views, taken on lines -5-5 and 66, Fig. 2.

Itis frequently the case that elevator shafts, which are to be provided with doors, are of but slightly greater cross sectional area than the car, so that but little space intervenes between the car and the Wall of the shaft, and consequently it is often necessary to cut through the wall of the shaft to obtain the requisite room for the shaft door opening and closing mechanism operated by the movement of the car. It frequently happens, however, that the elevator shaft is so constructed or so placed with reference to adjoining rooms that it is impracticable to cut through its wall, and often it is impossible to provide such a shaft with elevator shaft doors.

Our present invention has been designed for the express purpose of use when but little space intervenes between the car and the adjacent wall of the elevator shaft to be provided with the dooropening and closing mechanism, and is of such construction as to occupy but a minimum amount of space vWhen the door is open, and as to permit of its ready and practical operation in order to reduce to a minimum the amount of power required in operating the same.

A represents the elevator car guides or supports, only a portion of which are here illustrated, and B- the elevator car, which is shown as interposed between two floors O-O having elevator doors -OO.

At the lower end of the car B are rounding faces bbwhich, as presently described, actuate our door operating mechanism to open the door O'O'-, and at the upper end of the car -B is a curved face --b, which engages the under faces of said doors in the usual manner, and elevates them to the position assumed by the lower doors at Fig. 1. The elevator shaft doors or guards O'-C, which are of the same construction as the doors shown in the aforesaid patent, No. 458,627, are hinged at -cc to supports -C O secured to the top face of the floors OU or other suitable support at the side of the guides or supports AA. As clearly seen at Fig. 1 the guides or supports AA are formed with guide ribs A-A'-, which are engaged by suitable guide arms B'B- upon the elevator car B-. Portions of said guide ribs A' A directly above the doors C-C- are cut away for enabling the doors to swing upwardly beneath the said ribs, and, as also clearly seen at Fig. 1, the doors GO'- are formed on theirnormally lower faces with ribs C C which, when the doors are open, are aligned with the ribs A'A and form, essentially, continuations of said ribs for supporting and guiding the elevator car when passing the doors O' DD are plates secured by suitable fastening means d to the corresponding faces of the car guides or supports AA', and -E-E are plates secured by suitable fastening means eto the central portions of the top faces of the doors O-C'-. As best seen at Figs. 3 and 4 each of the plates --D is formed with a projecting spindle D'--, and, as best seen at Figs. 3 and 6, each of the plates -E is formed with aprojecting ear E-.

FF- are door levers each consisting of a pair of bars f hinged at their lower ends to a pin emounted in the corresponding ear E, and GG are links each consisting of a pair of bars gg arranged at the opposite sides of the corresponding levers FF and having their lower ends hinged bya pin f' to the central portions of said levers -FF, and their upper ends provided with eyes -g'g registered with the corresponding spindles DD'. Consequently one of the levers F and one of the links G form a toggle between one of the shaft doors E and the corresponding support or guide A, and, as said door moves upwardly as presently described, the lever -F- swings on the pin eand the link G on the spindle D, and the lever F swings between the bars -gg of the link G until its normal lower end is almost directly above its normal upper end, as shown at Fig. 1.

HH are actuating levers each having one end hinged at h to the corresponding link G and the other end formed with a downturned extremity h'. As clearly seen at Figs. 1 and 2 each of the levers H is of slightly less width than the distance between the bars g-g of the corresponding link G in order that the outer end of said link may swing freely between said bars, and said lever is formed on its normal lower face with a rib h'' of less width than its normal upper face.

II are links each having one end hinged at 'i to the central portion of the corresponding lever H,, and the other end hinged at t" to the normal upper end of theadjacentleverF-. Said linksII are each preferably constructed of a lower section I formed with a screw-threaded upper end t' and an upper section --I composed of a central bar i formed with a screw-threaded socket for engaging the screw-threaded end -z' of the lower section I and with upwardly extending arms i t' arranged on opposite sides of the rib h of the lever H and formed with eyes 2' -?l for receiving the pivotal pin z' previously described. As the elevator car is descending the rounding faces bb engage the normal upper faces of the actuating levers HH and depress said levers into the position shown at Fig. 1. The links II thereby depress the normal upper ends of the levers FF, rock said levers on their pivots ee,and elevate the normal lower ends of said levers FF for opening the doors. As clearly seen at Figs. 1, 2 and 3 the links -II are arranged in a plane interposed between the planes of the inner faces of the bars gg composing the links GG, and are free to swing between said bars, thus permitting our improved door operating mechanism to operate in a very limited space not greater, if desired, than the width of the guides or supports AA. Moreover, as is evident to one skilled in the art, the construction of our improved door operating mechanism is such as to permit the door to be opened with a minimum amount of power, and to cause the door when opening or closing to move at a substantially uniform speed.

The operation of our invention will be readily perceived from the foregoing description and upon reference to the drawings, and it will be particularly noted that the same is simple in construction, practical in operation, durable and effective in use, and that it occupies but a minimum'amount of space.

Having thus fully described our invention, What we claim as new, and desire to secure by Letters Patent, is
