SPECIFICATION forming part of Letters Patent No. 458,627, dated September 1, 1891.

Application filed March 14, 1891. Serial No. 385.045. (No model.)

To all whom it may concern:

Be it known that I, EDGAR W. IloUsnR, 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.

My invention relates to improvements in elevators, and has forits object the production of a simple and effective device for automatically opening and closing the elevator'- doors as the car moves up and down; and to this end the invention consists, essentially, in hinged elevator-doors, a toggle for supporting the doors having one lever pivoted to a door and the other to a stationary support, as the car-guide beam, a pivoted lever secured to the elevator-car-guide beam and provided with a weighted extremity projecting into the path of the elevator-car, a link between said toggle and the opposite extremity of the pivoted lever, a car having curved bearing-faces adapted to engage the projecting extremity of the pivoted lever, a cut-out in the car-guide beam above the elevator-door for receiving the same, a guide-rib on the normal lower face of the elevator-door, and 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 l represents an elevation of two floors, two separate pairs of elevator-doors and their actuating-levers, and an elevatorcar midway between the two pairs of gates, the upper one being shown as closed and the lower one as just on the point of closing. Fig. 2 is a similar enlarged view illustrating the elevatoncar as in its position assumed when the gates are entirely opened and the floor of the car is in alignment with the licor of the building. Fig. 3 is a rear view of a portion of the car-guide beam, the elevator-door, and the levers for actuating the door. Fig. 4C is a horizontal sectional view taken on line :c Fig. 2; and Fig. 5 is a transverse sectional view taken on line y y, Fig. 4.

A and A represent the upper and lower oors of a building having an elevator-well C, in which is movable an elevator-car B of any desirable form and construction.

D represents the elevator-doors, which are preferably hinged at d to a bearing d upon the floor of the building. As preferably constructed, the doors are arranged in pairs, each one of the doors being of substantially the same area and having its free extremity in close proximity to the adjacent edge of the other for entirely closing the openings between the fioors. The doors are also of somewhat greater width than the elevator-Well in order that their opposite edges may rest upon the floor A A and be thereby firmly supported and adapted to safely hold superimposed weights.

E represents a toggle formed by a pair of levers e and c', having their adjacent extremi* ties pivoted together at e2 with the opposite extremity of the lever e, pivoted to a lug e3 upon the elevator-gate D, and the opposite extremity of the lever e pivoted to a support e4, preferably mounted upon the elevator-guide beam F, although it may be otherwise mounted, if desired. The outer extremity of the lever c is screw-threaded and provided With an adjustable connection e5, whereby the length of the toggle maybe somewhat adjusted to conform to the exact requirements.

G represents a lever pivoted at g to thev beam F and formed with one extremity G curved, weighted, and projecting into the eievatorecar path. The opposite extremity G2 is connected to the common pivotal point of the toggle-levers e and e by a link H.

For the purpose of simplicity of 1nanufacture the opposite extremities of the lever G are formed separable one from the other and secured together by rivets or bolts g', the weighted end being preferably composed of cast metal and the other of bar or band iron.

The elevator-car Bis provided with a guideway B', adapted to engage a rib F upon the beam F and guide the car in its upward and downward movements.

Provided upon the upper extremity of the elevator-car at one side of the way B is a bearing-face B2, preferably composed of a semicircular or curved bar secured at its opposite extremities at b and braced at its cen- IOO tral portion by bars b. As the car moves upward this bearing-face encounters the lower face of a bearing rib or face D on the do'ors D and forces them upwardly into a recess or cut-out F2, formed in the guide-beam for their reception. On the under face of these doors is a rib or face D2 at one side of the rib D', which latter rib D2, when the gate is in its upward position, forms a continuation of the rib F and serves to guide the elevator in its onward movement. As the elevator-doors are moved upward the normal lower extremity of the lever G is elevated above the weighted end, which is correspondingly depressed and retained in said position by contact with a bearingface B2, formed on the outer wall of the elevator-car in alignment with the face B2. At the lower extremity of the car B is a curved bearing-face B4, which forms a continuation of the vertical face B3, and as the elevator-car continues its upward movement the weighted end G of the lever G bears against the curved bearing-face B3 and permits the door to gradually close as the elevator-car ascends. On the contrary, when the elevator descends the bearing-face B4depresses the weighted end G and elevates the elevator-doors into their opened position.

As preferably constructed the bearing-face B3 is composed of a hardwood bar having its lower face secured to the elevator-car ioor and its upper face supported b v a brace b2, projecting from the top cross-bar b2. Formed at the opposite extremities of this face B2 are cut-outs for receiving the ends of the faces B2 and B4, which are preferably composed of iron or steel bars.

This construction of automatic elevatorgate may be readily attached to any desired form of elevator-car without extra fitting or excessive expense, since the only thing necessary is to secure to the ordinary guide-beam the pivotal pin g and the support et, provide said guide-beam with a cut-out F2, secure to the door the lug e3, pivot between the lug e3 and the support e4 the toggle E, connect the toggle E to the pivoted lever G by the link l-I, and provide upon the elevator-car the bearing-faces B2, B2, and Bt. By practical use I have ascertained that this construction of elevator-gate is also very quickly and noiselessly operated without the slightest liability of any failure in its operation.

The operation of my invention will be readily perceived from the foregoing description and upon reference to the drawings, and it is evident that considerable change may be made in its detail construction and arrangement without departing from the spirit thereof.

Having thus fully described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

l. In an elevator, the combination of an elevator-car, a movable door, a pivoted lever G, having one extremity weighted for causing said lever to assume its normal position, a toggle E, consisting of levers e and e', hinged together at their adjacent extremities, with the opposite end of one of the levers c hinged to said door, a support c4 for the opposite end of the other lever e', and a link H between said toggle and one extremity of said weighted lever, substantially as and for the purpose set forth.

3. In an elevator, the combination, with a car B and a movable door D, of an upright F, projecting along the elevator-well, a lever G, pivoted to said upright, with one extremity extending into the path of the car B, a support el on said upright, a toggle E, consisting of levers e and c', one lever e being pivoted to the door D and the other lever e being pivoted to the support e4, and a link H between said toggle and the lever G, substantially as described.
