. SAFETY DEVICE FOR ELEVATORS.

Specification of Letterslatent. Patented July 12 1921.

Application filed February 16, 1920. Serial No. 358,849.

To all whom it may concern:

Be it known that I, JOHN H. BnRerIAps, J r., a citizen of the United States, residlng at Louisville, county of Jefferson, and State of Kentucky have invented a new and useful Safety lfievice for Elevators, of which the following is a specification. V

This invention relates to safety devices for elevators.

An object of the invention is to provide means for preventing accidents in the operation of elevators, more especially such as are due to an object, as the foot of an operator, projecting beyond the edge of the elevator, and being caught between the floor of the elevator and the ceiling of the room, as the elevator ascends. 7

With the foregoing and other objects in view, the invention consists of the novel construction and arrangement of parts illustrated in the accompanying drawing, which forms a part of this specification, wherein is set forth an embodiment of the invention, but it is to be understood that such changes and modifications ma be resorted to as come within the scope of the appended claims.

In the drawing, wherein similar reference characters designate like parts in the several views, Fi re 1, is a perspective view of a portion 0 an elevator equipped with an embodiment of the. invention; and Fig. 2, a section on line 22 of Fig. 1.

Referring now in detail to the drawing, the reference character -10 design one of a pair of vertical timbers, of which one is positioned oneach side of an elevator shaft which extends upward through openings, or hatchways --11 in floors 12 and extends the full height of the building. car -13- which comprises a platform -14, side posts 15 and a head beam 16- is raised and lowered by suitable means such as a rope 17 attached to the head beam. Shoes -18- on the posts 15 bear against the sides of guide rails 19- which are secured to the vertical timbers.

The car is usually closed in on three sides by a railing or wall -j20-, thereby permitting access thereinto from one side only. A wing --21 is pivotally suspended by suitable means such as hinges -22 at the ates lower edge of each floor opening on the side thereof toward which. the car opens. The wings are suspended from the ceiling or from a joist of each floor and in such'relaitionship to the hatchway that when-inactuated position its inner face will lie in substantially the same vertical plane as the side -23 of the hatchway, and it may extend the full width of the hatchway, or only such a part thereof as corresponds to the opening from the car. Normally thewing is biased by suitable means such as a spring 24, so that it stands at an angle to the elevator shaft with its lower edge spaced from the "opening. A slidingbar 26 is connected by. one end to a stud 27 extended from an end of the wing. The bar extends through a slot 28- in the vertical timber Y and is bent atan angle so that a roller 29-- on its inner end lies in the path of a cam block 30 positioned on the post, 15, of

the elevator, the arrangementbeing such that as the platform in its upward travel approaches an opening, the cam 30 will engage the roller on bar 26, shifting it longitudinally and drawing the wing t o which it is connected down fiushwith the side of the hatchway. The wing as it is drawn down will push before it anything that may project over the edge of the platform, such as the operators foot, thereby preventing it from being injured by being caught between the platform and the edge of the opening.

Having thus described a my invention so that those skilled in the art pertaining thereto can make and use the same, a

I claim:

1. In combination a floor, having an opening, an elevator guide at the side of said opening, an elevator movable through the opening, a wing pendent below said floor in aplane substantially the same as a side of said opening, means normally biasing the lower edge of said wing away from the ropen'ing,'a bar pivoted to said wing and ex- 1 opening and having an upright member slidable on said guide, a Wing pending below said floor in a plane substantially that'of the side of the opening, a spring normally 7 holding thelower edge of said wing away fromthe opening, a bar pivoted to said'wing and extending through the elevator. guide,:, 7
