GATE FOR ELEVATOR-$11M TS.

Specification of Letters Patent.

PatentedFeb. 23, 1915.

Application filed May 12, 1914. Serial No. 837,966.

To all whom it may concern:

Be it known that I, AGHILLE F. BATAILLE, a citizen of the United States, residing in the borough of Manhattan, in the city, county, and State of New York, have invented an Improvement in Gates for Elevator Shafts, of which the following is a specification.

My invention relates to gates for closing the openings to the elevator shaft at each floor of a building, and particularly to so called folding or eXpansible gates, and mechanism for locking the same in an open or closed position.

The details of my invention are hereinafter particularly described.

In the accompanying drawings :Figure 1 is an elevation looking from within the elevator well or shaft, showing my improved gate in a closed position. Fig. 2 is a vertical section on the broken line :12 00, of Fig. 1, showing also in dotted lines the position of the gate and locking mechanism when the gate is open, and also showing in dotted lines the car and mechanism carried thereby in position opposite the gate. Fig. 3 is a transverse section on the broken line 3 y, of Fig. 1, showing also in dotted lines the gate in an open position, and a plan view of the front portion of the platform of the car and catch carried thereby for holding the gate open. Fig. 4.- is an enlarged sectional view about on the broken line :12, 00, of Fig. 1, showing the gate locked in a closed position, and also illustrating the contact shoe carried by the car in a position about to operate the mechanism for unlocking the gate from its closed position. Fig. 5 is a view similar to Fig. 1, but showing the shoe carried by the car in contact with the locking mechanism and the gate unlocked from its closed position, and Fig. 6 is an enlarged sectional view on the broken line a, z, of Fig. 3.

Similar reference characters indicate like parts throughout the several views.

1 indicates an elevator well or shaft having a door-opening 2, above a landing or floor 3.

4: designates a car movable up and down in the shaft 1, and 5 indicates a folding gate which controls the opening 2.

The supporting frame for the gate consists of the two vertical members 6, 7 and transverse members 8, 9. This frame is secured to the wall of the well or shaft 1 in any suitable manner surrounding the opening 2 therein, or it may be fitted and secured within a recess in the Wall.

l0, 10, indicate two upright members arranged opposite each other adjacent the frame member'6, and permanently secured at their top and bottom to the transverse frame members 8, 9. These uprights have right angled longitudinal flanges 11 on each side, and are spaced apart by blocks 12 at the top and bottom, and at intermediate points, if desired. Bolts or rivets 13 connect the uprights 10 together.

14.1-1 and 15l5 and 16-16 indicate additional uprights of similar shape and spaced and connected, in pairs, in the same manner as the uprights 1.0, but these uprights l t, 15 and 16 are not secured to the supporting frame. These uprights 14, 15, 16, together with the lazy-tongs or pivotally connected slats 17, form the folding gate. One of the members of each pair of uprights 14 and 15 is extended above the transverse frame member 8 and its top bent over, in which portion is pivoted a grooved wheel 18, the top edge of the transverse member 8 forming a track for the same. The upright 16, at its top, is also provided with a similar grooved wheel for the same purpose. I have shown in connection with this upright an attached piece 19, for the wheel, but if preferred one member of this pair of uprights may be extended above the transverse member 8 similar to the pairs of uprights 1d and 15.

20 indicates a handle or suitable grip secured to the outer surface of the upright 16.

The slats 17 are pivotally connected by pins or rivets 21.

The lazy-tongs at one end are pivotally connected between the uprights l0, imd at the other end between the uprights 22 and 23 represent two cross bars pivotally connected together at one end by a rivet or pin 24, the other end of the cross bar 22 being pivotally connected to the upright 10, while the other end of the cross bar 23 is pivotally connected to the upright 16 by a pin or rivet 25. Stops 60, upon the uprights 14 and 15 support these cross bars in a horizontal position when the gate is closed. These cross bars fold with the gate and when the gate is opened and return to a horizontal or nearly horizontal position when the gate is closed. These cross bars act as a back brace for the gate when closed.

26 indicates a cross piece secured to the upper surface of the transverse frame member 9, having a longitudinal groove 27 in its upper surface within which the projecting lower ends 28 of the bottom spacer blocks, between the pairs of uprights 14 and 15, slide.

29 designates an arm, one end of which is secured to the lower part of the upright 16, from which it is bent outwardly at an angle and again bent downwardly so that its free end is below the gate for the purpose hereafter described.

30 indicates a vertically sliding block fitted between the two upright members 10, and retained therein by the longitudinal flanges 11 upon such members. This block 30 has a cross-head 31 which extends beyond the outer surface of the upright 10 on one side.- The lower portion of the block 30 is reduced and at the bottom of this reduced portion there is a vertical slot 32. The upper end of the gate slat 33 enters this slot 32 and is pivotally connected therein by a rivet or pivot pin 34. It will readily be seen therefore that when the gate is opened the block 30 will be forced upwardly between the upright members 10, and that when the gate is closed the block will be drawn downwardly.

35 and 36 are two spaced guide strips, bent around the outside of the two upright members 10 in parallel line, and secured in position by screws or rivets 37. The ends of these guide strips extend a predetermined distance beyond the outer surface of the upright members 10.

38 designates a locking member fitted to slide between the guide strips 35 and 36, on one side of the upright 10, and bent at right angles to fit between the said strips at the rear of said uprights. The free end of this member 38 is again bent at right angles to come between the projecting ends of the strips 35 and 36, so that when the gate 5 is closed this bent end 39 of the member 38 will rest upon the top surface of the cross head 31 of the block 30. The other end of this member 38, or in other words the end of that portion which slides between the guide strips 35 and 36 is bent at right angles and at this point is secured to a bowed spring 40 of fiat metal by rivets 41. The upright members 10 are sufiiciently near the vertical frame member 6 that the sliding portion of the member 38 is properly retained between the guide strips 35 and 36 by said member 6.

42 indicates a shoe carried upon the car 4.

The gate is normally locked in a closed position by the member 38, its end 39 being in contact with the top of the cross head. 31 of the block 30, and said member being incapable of vertical movement by means of the guide strips 35 and 36.

When the car 4 comes in alinement with the gate at any floor, either in ascending or descending, the shoe 42 carried upon the car comes in contact with the bowed spring 40, compressing the same and thereby forcing the member 38 backward sufiiciently to release its end 39 from contact with the top of the cross-head 31 of the block 30, as shown by dotted lines in Fig. 2 and full lines in Fig. 5. The block 30 is now free to move upward when the gate is opened by grasping the handle 20 and drawing the upright 16 toward the fixed upright 10, the gate slat 33 acting to cause such movement of the block 30. This condition will prevail so long as the car 4 remains stationary opposite the gate.

The gate is locked in an open position by means of a spring operated catch lever 43, connected with the platform 44 of the car, and the bent arm 29 carried by the upright 16 of the gate.

45 is a housing arranged in the front of the car platform 44 about centrally thereof in which the catch lever 43 and its operating mechanism are contained. The lever 43 is pivoted at 46, and its catch head is nor mally pressed outward through an opening 48 in the face plate 49, of the platform 44, by a spring 50, one end of which is secured to said face plate 49, by screws or rivets, its free end resting over and upon the free end of the lever 43. The other end of the lever 43 is provided with a slot 51 having a beveled portion 52.

53 is a push pin passing down through an opening 54 in the top of the housing 45, its lower end fitting within a vertical slot 55, in the bottom of the housing. This push pin 53 is also received within the slot 51 in the end of the lever 43, and is provided with a projection 56 having a beveled side in contact with the beveled portion 52 of said slot 51. The pin 53 has an integral annular flange 57 on that portion coming immediately below the under surface of the lever 43, and 58 is a coiled spring surrounding the pin beneath said flange, one end of which bears against the under surface of said flange while its other end bears upon the bottom of the housing surrounding the vertical slot 55 therein. This coiled spring normally holds the head 59 of the pin 43 slightly raised in the opening 54. By depressing the pin 53 the beveled projection 56 thereon,

acting against the beveled portion of the slot 51 in the lever 48, will turn said lever on its pivot 46, thereby drawing its catch 17 within the housing, and when pressure upon the head 59, of the pin 53, is released the coiled spring 58 will expand and force the pin upward again, and at the same time the catch 47 will be projected through the opening 48 by the spring 50.

The front surface of the catch 47 is beveled outwardly so that when the gate is opened the bent arm 29, carried on the gate, will ride over this beveled portion of the catch, forcing it within the housing 415 against the tension of the spring 50, and when this bent arm 29 passes said catch, the spring 50 throws the catch outwardly in front of the arm 29, thereby locking the gate in an open position. This is clearly illustrated in Fig. 3. The gate will thus be held by the catch 47, so long as the car 4 remains stationary with the shoe 42 in contact with the spring 40, but upon moving the car in either an upward or downward direction, the arm 29 is drawn away from the catch 17 61 indicates a flat spring, one end of which is secured to the fixed uprights 10, by rivets or screws 62, while its free end projects outwardly therefrom. When the gate is opened the upright 14:, contacts with this spring, compressing the same. When the arm 29 is released from the catch 17, this spring is allowed to expand thereby forcing the gate toward its closed position, and to insure a full closure of the gate I provide one or more spiral springs 63, which are attached to the pivot pins 21 of the gate slats 17, in vertical lines as shown in Fig. 1, tending to draw said pins toward each other, thus expanding the lazy-tongs and throwing the gate across the door-way.

The jointed cross-bar 2223 not only acts as a back brace for the gate slats, but limits their expansion, thereby preventing the uprights 16 striking the frame with too great force.

Should the operator desire to close the gate before starting the car in either direction, he may do so by placing h1s foot upon the head 59 of the push pin 53 and depressing said pin, thus withdrawlng the catch 47 and releasing the arm 29 when the gate will close by the action of the springs (31 and 63.
