GATE SECURING AND CLOSING MEANS.

,.App1ication fiIedMay 14, 1325. Serial No. 30,344.

To all coho-m it may concern:

' Be it known that I, Fnnnnnroii J. LYNCH,

eitizen of the Dominion of Canada, residing at NewvlVestminster, in the Province of British Columbia, Canada, have invented certaindnew and useful Improvements in Gate Securingand GlosingMeans, of which the following is a specification.

This invention relates to a means for rapidly closing and securing a door or gate at iording entrance and exit to a building or the like, the same being operable by electric means from any part of the building.

It is particularly applicable to a door of that class wherein a series of lattice levers pivotally connect a series of uprights, so as to be slidably extensible across a doorway from one or both sides thereof, the inner upright being secured to one of the sides of the doorway and the outer upright hung from a sheave movable on a rail extending across the upper or transom rail of the doorway.

The invention is particularly described in the following specification, reference being made to the drawings by which it is accompanied, in which:

Fig. 1 shows he door in the open position closing the doorway.

Fig. 2 is a view of the same when the door is withdrawn to open the doorway, and

Fig. 3 is an enlarged detail of the electric release mechanism.

In these drawings 2 represents the'doorway to be closed, 3 one of the side posts and l the transom rail of the doorway. The gate by which the doorway 2 is closed consists of an upright 5 secured to one of the side posts 3, and 6 is the outer upright of the gate which is suspended at 7 from a track rail 8 secured to the transom rail 4 and extending over the doorway 2.

The inner and outer uprights 5 and 6 are I connected together by an upper and lower series of lattice levers 10 pivotally connected at 11 to one another, and at 12 to a series of uprights 13, so that the gate may be extended from the fixed upright 5 to close the doorway, as shown in Fig. 1, the suspension 7 of the outer upright 6 travelling along the track rail 8.

Extension of the gate from the position shown in Fig. 2 to close the doorway, as shown in Fig. 1, is effected by a bar 15, one end of which is pivotally connected at 16 to the outer upright 6 of the gate and the other end at 17 to a weight 18, which is vertically movable within a casing 19 formingthe side 3 of the doorway.

.The casing 19 has a slot 20 to permit the bar 15"to be connected to the weight 18 and to move down with it to the horizontal position. The length of" the bar 15 is such that when in the horizontal position, the gate is extended to its full limit to closethe door space and a stop is provided in the easing to check movement of the weight when the bar is in the horizontal position.

At the upper limit of its movement the weight 18 is sustained in the casing 19 by a latch 21, the end of which is connected by a link 23 to the end 24 of a lever 25 pivoted at 26 to the side wall of the doorway. The free end of this lever 25 is adjacent the pole of an electromagnet 27 in a normally open electric circuit 28 energized by a battery or by connection to other source of electrical energy. This circuit is closable at a contact 29 at a convenient place in the buildmg.

On the link is secured a projection 30 which engages an angled projection 31 from the wall of the casing 19.

When the circuit 28 is closed and the clectromagnet 27 energized, the free end of the lever 25 is drawn up into contact with the pole of the electromagnet and the link 23, connected to the other end of the lever 25, is drawn down and by engagement of 30 with the incline 31, the upper end of 23 and the latch 21 connected to it are drawn outward and disengaged from the weight 18. The weight then falls and in falling projects the bar 15 from the inclined upright position shown in Fig. 2 to the horizontally extended position, as shown in Fig. 1. The weight 18 is retained at its lower position by the latch 32 of a lock The essential features of the invention are the horizontally extensible bar 15 connected between the outer end of an extensible gate 6, and a latch supported weight 18; and the means for withdrawing the latch 21 and permitting the weight to fall to extend and secure the gate to close the dorway 2. The electric circuit 28 is such that the latch may he released from any position in the building so that in the event of any requirementfor closing the gate, as for instance, the pres ence of bandits, the gate may be closed and escape prevented.

Having now particularly described my invention, I hereby declare that what I claim as new and desire to be protected in by Lettors Patent, is:

1. Means for shutting and securing a sliding gate to close a doorway, said means comprising the combination with the gate, of a weight vertically movable within a casing on one side of the doorway, a bar pivotally con: nected at one end to the weight and at the other endto the outer style of the gate, a latch sustaining the weight at the upper limit of its movement and the gate open, and means for withdrawing the latch and permitting the weight to fall whereby the gate is extended across the opening.

, 2. Means for extending a sliding gate to close a doorway and for securing it in the closed position, said meanscomprising the. combination with the slidable gate, of a cas ing on the side of the doorway from which the gate is extended, a weight Vertically movable in the casing, a bar pivotally connected at one end to the weight and at the other to the outer style of the gate, a latch retaining the weight at the upper limit of its movement in the casing, means for withdrawing the latch and permitting the weight to fall, whereby the gate is extended across the doorway, and means for retaining the weight at the lower limit of its movement with the gate shut.

In testimony whereof I al'lix my signature.

FREDERICK J. LYNCH.
