SPECIFICATION forming part of Letters Patent No. 392,5e6, dated November 6, 1888.

(No model.)

To aZZ whom, it may concern:

Be it known that I, JACOB ENGEL, a citizen of the United States of America, residing at New Bedford, in the county of Ooshocton and State of Ohio, have invented certain new and useful Improvements in Self-0losing Hatchways; 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, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to certain new and use ful improvements in door-operators for hatchways, the object of the same being to provide an improved means for opening and closing hatchway-doors of an elevator shaft as the car is about to pass said door in either direction; and it consists in providing the doors of the hatchway with geared segments, which engage with bell-crank segments having gear-teeth, said segments being connected to pivoted levers, which are operated to open and close the hatchway-doors, the bottom portion of the cage engaging with thelevers on its downward movement, while the upper portion thereof engages with the under side of the doors on its upward movement, the parts being organized as shown.

My invention also consists in the construction and combination of the parts, as will be hereinafter fully set forth and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view of my improved automatic closer for hatchway-doors. Fig. 2 is a sectional view taken through the line or x of Fig. 1. Fig. 3 is an edge view of the cage detached.

A A refer to the uprights of the elevator, the inner edges thereof being provided with guides to a or projecting tongues, which lie within the grooves 11, formed in the side pieces of the cage. These uprights above each of the doors are provided with cut-away portions A, within which the doors will lie when swung upwardly to a vertical position, and the under sides of the doors B B are each provided with strips a, which will form with the tongues a continuous guides for the cage.

the uprights A, and around said pins are placed coiled springs cl, one end of which is made fast to the upright, the opposite end being secured to the bell-crank segment, so as to have a tendency to throw the outer end thereof downwardly and hold the doors normally closed. Instead of employing aspring in this connection the outer ends of the bell-crank segments may be weighted, or weights may be attached to the rods, which extend upwardly therefrom. I, however, prefer to employ the springs, as they can be so adjusted as to ease the closing movement of the hatchway-doors. To the outer ends of the bell-crank segments D are pivotally secured rods E,the upperends of which are attached to the outer ends of bent levers F, which are pivotally attached to the uprights substantially on a line with the pivots of the bellcrank segments D. These levers F are of such alength that they extend beyond the edges of the uprights, so that the cage will engage therewith on its downward movement, and when the ends of these levers are depressed, they, being connected to the segments hereinbefore described, will operate the said segments to raise the doors and permit the passage of the cage through the hatchway.

The cage is provided with a curved bar, G, located to one side and attached to the main frame thereof, and the bottom of the platform adjacent to its corners is provided with rollers g g, secured in suitable bearings,which will contact with the long end of the lever. When the elevator is drawn upward, this curved bar G, attached to the cage, will contact with the under sides of the doors and open the same, and while the platform is level with the floor the ends of the levers will bear against the sides of the aforesaid bar G, and as the cage is moved upward the long ends of the levers will contact with the rollers, which will cause the levers to move slowly, so as to not close the door with undue jar.

I am aware that prior to myinvention ithas been proposed to provide self-closing hatchways with an arrangement of pivoted levers and weights connected to the doors, so that they will be opened and closed by the passage of the cage or car, and I do not claim such construction, broadly; but

What I claim as new, and des re to secure by Letters Patent, is-

1. In an automatic hatchway-door operator, the combination, with the casing and doors, of toothed segments secured to the hinge edge of the doors, bell-crank levers pivoted to the easing and provided with segmental racks meshing with the toothed segments, levers F, pivoted to the casing above the bell-cranks with one end projecting into the elevatorshaft, and rods connecting said levers with the bellcranks, substantially as described.

2. The combination, with an elevator shaft and cage, of upwardly-opening doors hinged in the shaft and provided on their hinge edges with toothed sectors, bell-crank levers pivoted to the shaft-casing and provided at one end with a segmental rack, springs secured to the casing and levers to move the levers in one direction, levers F, pivoted to the casing with one end projecting into the shaft in the path of the cage, and rods E, connecting the other ends of said levers with the bell-crank levers, substantially as described.

3. The combination, in a device for operating hatchway-doors, of a segment, 0, having gear-teeth, a bell-crank segment pivoted to the uprights, so as to engage with the segment 0, a spring, d, embracing its pivot, the ends being attached to said segment D and to the upright, connecting-rods E, and pivoted lever F, and the cage provided with rollers g and a bar, (1-, or angle-iron, the upper portion of which is curved so as to contact with the under side of the hatchway-doors upon the upward movement of the elevator, the parts being organized substantially as shown, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JACOB ENGEL.
