DOOR OPENING, CLOSING, AND LOCKING DEVICE.

SPECIFICATION forming part of Letters Patent No. 619,626, dated February 14, 1899.

Application filed September 26, 1898. Serial No. 691,921- (N model.)

To all whom it may concern.-

Be it known that LELI B. SLONACHER,a citizen of the United States, residing at Greensburg, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Door Opening and Closing and Looking Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to door opening, closing, and locking devices; and it consists, essentially, of an actuating-motor having controlling mechanism, an irregularly-channeled slidable device connected to said controlling mechanism and adapted to be operated by a projection on an adjacent movable object, and a door-operating lever attached to an opposite part of said motor.

The invention further consists of the details of construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

The object of the invention is to automatically open and close a door of an elevatorshaft and dispense with the necessity of manual operation for this purpose and always insure a tight closure which will resist exterior efforts to dislodge or unfasten the same, and thereby avoid accidents arising from carelessness or neglect.

In the accompanying drawings, Figure 1 is a perspective view of a portion of an elevator shaft and cage in dotted lines, showing the arrangement of the improved mechanism. Fig. 2 is an enlarged elevation of the mechanism attached to the shaft and broken through in parts. Fig. 3 is a section on the line w a: of Fig. 2, looking in the direction of the arrows. Fig. 4 is a detail view of the engaging device attached to the elevator-cage. Fig. 5 is a section on the line y y of Fig. 2.

Referring to the drawings, wherein similar numerals of reference are employed to indicate corresponding parts in the several views, the numeral 1 designates a cylinder of suitablelength and resistance and having opposite heads 2. Secured to upper and lower sides of the opposite heads 2 by their connections are valve globes or

casings

3, 4, 5, and 6. Thesevalve-casings have suitable slidevalves therein, which may be of any preferred construction, and to the upper side of valves 3 and 4 a feed-pipe 7 is secured and runs from any suitable point Where a source of supply of a propulsive medium is located. To the valves 5 and 6 a discharge-pipe 8 is also attached and can run away from the mechanism any distance. Each pair of

valves

3 and 4 and 5 and 6 have connected to the valve-stems 9 and 10 thereof

tubular rods

11 and 12. All of the valve-stems from the valve: casings extend inwardly toward each other, and at one

end arms

13 and 14 are connected to the

rods

11 and 12, respectively, and also pivotally attached to a lever 15, which is fulcrumed, as at 16, on one of the heads 2 of the cylinder. The upper end of said lever 15 passes through a cylindrical casing 17 and is secured by a screw or bolt 18-, working in slots 19, springs 20 being located within the casing to cushion the movement of the lever and avoid a sudden jar on the

arms

13 and 14 and the

rods

11 and 12. The cylindrical casing 17 has a screw-cap 21 at one end for the purpose of providing convenient means of adjusting the several parts, and pivotally secured to the outer end of .said casing, through the medium of aiprojection 22, are a pair of connecting bars or rods 23, which are converged toward this point and have their diverging opposite ends movably attached to the upper and lower portions of a flange 24 of a link 25. This link is formed with a channel 26 by means of opposite downwardly-extending flanges 27, as shown in Fig. 5, and said channel is deflected at opposite ends and vertical at the center, as at 27 The opposite ends of this link are connected to sliding rods 28, movable in guides 29 and shift either to right or left.

In one head 2 of the cylinder 1 is a gland 30 and packing-nut 31, in which a piston-rod 32, connected to a suitable piston within the cylinder, has free movement, and this piston-rod is attached to a slide 33, movable on a guide 34, and at its outer end beyond the-point of nected to a link 35, which is movably at tached to a door-operatin g lever 36,fulcru med at 37 and having an upper enlarged slotted end 38, in which a turn-head 39, secured to the door, has movement.

On the elevator-cage an arm or bolt 40 is secured and has on its outer end a Wheel 41, which is yielding and slightly spring-actuated through the medium of a spring 42, surrounding said bolt or arm. This wheel is adapted to ride in the channel 26 of the link 25 and first enters through one of the deflections in accordance with an upward or downward movement of the cage and throws the said link in one direction and afterward in the reverse direction when reaching the opposite deflection. Either of the movements of the link is continued until the central vertical portion of the channel is reached, when the door will be permitted to stand open and the cage will be at a proper position opposite the door-opening in the shaft.

The improved device is intended to be operated either by steam, water, air, or any other propulsive medium, which is conducted through the pipe 7 and after use passes-out through the pipe 8. Primarily the parts all act and are set to hold the door closed, and, for example, on the downward movement of the cage the wheel 41 strikes the upper part of the link 25 and gradually moves it to the right, thereby shoving the upper end of the lever 15 over in the same direction through the medium of the bars or rods 23, and opens the valves in the casings 3 and 6 and closes those in casings 4 and 5. This permits the propulsive medium to come in at the left end of the cylinder against the adjacent side of the piston and force the latter to the right, shove the piston-rod 33 outwardly, and the resistance that may exist on the opposite side of said piston is permitted to escape through the valve-casing 6 and pipe 8. This movement of the piston through the link 35 swings the lever 36 to the left, and the door is slid to the left and opened, the movement of the door being compensated for by the enlarged slotted end 38 of the lever 36. The opening movement of the door will continue until the.

roller 41 reaches the vertical portion of the channel 26, where a stop can be made, or if no stop is made the said roller then passes on down to the lower deflection of said channel,

gradually restoring the link to its normal position, and reverses the movements of the piston-rods 9 and 10 through the lever 15, closing the valves in the casings 3 and 6 and opening those in the casings 4; and 5, thereby permitting the previous charge in the cylinder to exhaust from the left end of the latter and simultaneously permit a charge to enter in the right end of said cylinder to move the piston toward the left and reverse the operation of the lever 36 and slide the door in the opposite direction or closed.

The proportions and dimensions of the several parts, as well as the details of construction, can be changed without departing from the nature or spirit of the invention.

Having thus described the invention, what is claimed as new is 1.
