EDMUND H. BENEDICT, OF TREMONT, ASSIGNOR OF ONEHALF HIS RIGHT TO GEORGE H. CLARK, OF BROOKLYN, NEW YORK.
IMPROVEMENT IN HATCHWAV-PROTECTORS.
Specification formirg part of Letters Patent No. 146,799, dated January 27, 1874; application filed September 9, 1873.
To all whom it may concern:
Be it known that I, EDMUND H. BENEDICT, of Tremont, Westehester county, New York, have invented certain Improvements in Hatchway-Protectors, of which the following is a specification My invention relates to devices for preventing accidents occurring from open hatchways; and consists in a novel construction, combination, and arrangement of parts, which have for their object to produce a hatchway-protector cylinders O G, plainlyshown in the perspective Xiew. These cylinders or posts are pivoted,
at either end, in bearings a a f f secured to the posts A A, and are capable of turning on their pivots. The groove cut in these cylinders is plainly shown in the perspective view and Fig. 3. It will be seen that it commences at one extremity and turns, in a gradual spiral, partly around the cylinder, when it continues in a straight line to within some distance of the other extremity, where it again turns, in a similar spiral, to the other end, but in the reverse direction. The two uprights of the elevator adjacent to the posts carrying the cylinders are each provided with a projecting arm on the collar E, which arms carry on their outer extremity an anti-friction roller, 0. The collar E may be provided with a set-screw for adjust ment. H H represent a sliding door, provided at either end with a rack, I. J J is an upright shaft, carrying the pinions m m, which gear with the racks on the sliding door H. n is a segment of a pinion secured on the cylinder Gr, which meshes with the lower pinion on the shaft J. is another segment of a crown-pinion, secured to the cylinder G below the flooring. it represent a horizontal shaft turning.
in proper beari n gs, and to which are secured three pinions-one, g, which gears with the crown-pinion on the cylinder G, and two others, h h, which work in racks k k, attached to the under side of the horizontal sliding door G which closes half the hatehway-openin g. B is a swing-door, which closes the other half of the hatchway-opening, is hinged to the floor at d, and operated by a segment of a crowngear, (1, attached to the cylinder 0. This segment-gear meshes in a pinion, b, secured to a short spindle, on which the arm 0, secured to the door B is keyed. a? is the rope by which theelevator is operated.
The parts, being constructedand arranged substantially as described,will operate, to open and close the doors of the hatehway, as follows The elevator, ascendin g the roller 0 on the arm projecting from the standard D, enters the groove in the roller G, and, in passing along the spiral portion of this groove, will turn the cylinder on its pivots. This motion of the cylinde-r will be communicated to the pinions m m and g. The former will operate on the racks I I and open the door H, while the latter, operating the shaft t i, on which are secured the pinions h h, withdraws the horizontal sliding door 0 The opposite arm now enters the groove in cylinder (3, and, passing along its spiral portion, turns the cylinder. This motion will be communicated to the pinion I) by the pinion a, and the door B will be thrown up. The arms now run in the straight portion of the grooves and hold the cylinder stationary, but, on arriving at the upper spiral of the grooves, a repetition of the foregoing operation is had, only in the reverse direction, and the doors are accordingly closed.
The object of showing the lllGUllfllllSlll lllldCl" the flooring in the drawings, for operating the horizontal sliding door, is for the purpose of illustrating two difierent ways of operating the doors for closing the hatchway-opening--'i. 0., this and the mode of operating door B but,
in practice, instead of this sliding door, ahinged door, similar to B can be arranged to swing downward, bein operated by the pinion 11 on the cylinder G.
I claim- 1. The combination, with the platform 13, provided with cams c, of the vertically-grooved cam-shafts O and G, sliding doors H and O and hinged door B all arranged and acting, in co-operation with each other, substantially in the manner described.
2. In combination with the cam-shaft G and door H, the segment at and ra-cks and pinions l I m m, or equivalents thereof, for automatically operating the door H, substantially in the manner described.
3. The combination, with the verticallyg'rooved calm-shafts O and G, swinging door 13", and sliding doors H and C of the segment a, and pinion b, racks I I, pinion m m, and
segment n, and racks 70 7c, pinions h h g, and
segment f, all constructed and operating, substantially as described and specified.
4. The doors B 0 combined with the rotating cam-shafts, arranged to open one above and the other below the floor, substantially in the manner described and specified.
