ELEVATOR-GATE.
SPECIFICATION forming part of Letters Fatent No. 415,848, dated November 26, 1889. Application filed August 16, 1899. Serial No. 321,045. (No model.)
.rection; and my invention has for its object the provision of a gate of the above class of a simple and improved construction, which will render it readily operative and thoroughly reliable and effective in its operation.
In the drawings, Figure 1 is a view in broken sectional elevation, showing the fioorof abuildin g, an elevator-entrance provided with a gate of my improved construction opened, and anelevator-car coincident with the entrance; Fig.
2, a similar view, the elevator-car being lowered and the gate closed; Fig. 3, a view in elevation of the gate folded; Fig. 4, a similar view of the same distended; Fig. 5, a broken section taken on the line 5 of Fig. 2 and viewed in the direction of the arrow, and Fig. 6 a broken sectional viewtaken on the line 6 of Fig. 5 and viewed as indicated by the arrow.
A is the frame of an entrance to an elevator-shaft, B the elevator-car, and C a folding gate secured in theframe A at one side of the entrance. The gate consists of horizontally-disposed lazy-tongs mechanism 2, on edge, as shown, pivoted toward one end to a supporting-frame D, secured and housed in the door-casing. The support D is in the form of a rectangular loop with horizontallydisposed parallel sides s, provided with 1011- gitudinal guide-slots .9. At the junction of their second pair of levers the lazy-tongs t are provided with a rigid pin r, projecting at opposite ends through and movable in the guide-slots s, and loosely connected toward one end with the pin 0 is a link 7*.
E is a shaft journaled upon the frame A, extending at one end toward the lazy-ton gs t and projecting at its opposite end into the elevator-shaft toward one side of the latter. At its firstnnentioned end the-shaft E carries a crank-arm q ,loosely connected toward its vided a rack p to engage the teeth of the pinion p and turn the latter during the movement past it of the elevator-car. Turning of the pinion 23 rotates the arm q and reciprocates the link 'r and the jointof the lazytongs provided with the pin 4, which, as it.
moves in a. backward direction, folds the lazy-tongs and distends them as it moves in a forward direction. The rack and pinion have a corresponding number of teeth, so that in the movement of the rack across the pinion a complete revolution is given the latter, which thus operates to open and close the gate. The rack 19 is located upon the elevator-car in position to cause it to have traveled just half its extent across the pinion when the floor of the elevator-car reaches the level of the floor of the building, which arrangement (the gate being first closed) will cause the gate to be opened its full extent when that level is reached. The gate is then closed by movement of the elevator-car in either direction.
If desired, the rack 19 may be divided at the middle and the two halves located at a distance apart in vertical line which will cause the gate to be opened before the floor of the elevator-car reaches the level of the floor of the building and be closed only after the elevator-car has moved some distance beyond that point.
Where, for the sake of appearance or additional safety, or both, it is desired to aiford a gate which will close the opening more effectively and be more pleasing to the eye than the lazytongs al0ne, I provide a curtain F to move with the gate and to stretch across the opening in front of the lazy-tongs when the gate is closed and fold out of the way when the gate is opened. The curtain is secured toward one edge upon a vertically-disposed spring-actuated roller 0, j ournaled in brackets 0 on the door-casing adjacent to the lazytongs, and toward its opposite edge it is secured-to a vertical rod 97. at the free end of the lazy-tongs. As the gateis closed the curtain unwinds from the roller 0 against the resistance of the spring, and the resilient force of the latter operates to Wind the curtain upon the roller again as the gate is opened. The curtain may be of any suitable material and as ornamental and attractive as desired.
WVhat I claim as new, and desire to secure by Letters Patent is- 1. In combination with an elevator-car, a folding gate comprising horizontally-disposed lazy-tongs supported atone side of the entrance, a shaft E, having a crank connected with the lazy-tongs and extending into the elevator-shaft, a pinion 13 upon the shaft, and a rack 19 upon the elevator, to engage the pinion as the elevator passes, and thus turn the shaft and crank and alternately fold and distend the lazy-tongs, substantially as described. I
2. In combination with an elevator car, a su1i)porting-frameD at one side of the entrance, provided with a guide 3, a folding gate comprising horizontally-disposed lazy-tongs piv- .otally supported in the frame D and provided at the junction of a pair of its levers with a laterally-extending pin 7", movable in the guide, a link a", pivotally connected toward one end with the pin, a shaft E, having toward one end a crank q, pivotally connected with the link and extending intothe elevatorshaft, and turning mechanism, substantially as described, upon the shaft E, actuated by the passing elevator to turn the shaft and its crank and fold and distend the lazy-tongs, substantially as set forth. 4
3. In combination with an elevator-car, a folding gate comprising horizontally-disposed lazy-tongs supported at one side of the entrance, a shaft E, having a crank connected with the lazy-tongs and extending into the elevator-shaft, a pinion 1) upon the shaft, a v
rack 19 upon the elevator, and a curtain F, secured at one edge upon a spring-roller 0, journaled at one side of the elevator-entrance, and secured at its opposite edge toward the free end of the lazy-tongs to unwind from the roller as the gate is closed and be Wound thereon again by the action of the spring as the gate is opened, substantially as and for the purpose set forth.
