'DOOR AND GATE CONTROLLING DEVICE.

Patented Feb. 1, 1921.

Application filed July 25, 1919. Serial No. 313,160.

To all whom it may concern:

Be it known that we, CLINTON L. WOLFE,

I gate controlling devices, and has for its primay manipulate the controlling means and.

mary object to provide means whereby the entrances of homes, stores, banking and other institutions may be closed, from a distant point, to either entrance or exit.

The invention is especially applicable to the doors of stores and banks, where it may become necessary, on account of a robbery or like disturbance, to automatically close the doors to the escape of one or more persons from the building. In its preferred embodiment, it is desirous of locating the controlling means, which is preferably electrical,

at a point remote from thedoor; as, for instance, providing a series of push buttons or switches under the store counter, or within 1 convenient reach of the clerk, whereby, in the event of a robbery or hold up, the clerk automatically close the door.

While the above general description sets forth the main features of the idea, there are further minor objects, such, for instance, as secondary controlling means, also located at a point distant from the door, for opening the same after the closing means has been actuated. It is also proposed to electrify or charge the. door, thus rendering it impossible for any one to force an exit or entrance after the door has been closed. This particular means, however, while operable froma point adj acentthe controlling means, should be independent of the controlling means, as in every caseitmay not be desirable to electrify thedoor, certainly not to the extent that the current could not be cut oil when the door-openingmeans has been actuated to permit an entrance to be had.

to enable access to be had to the building by oflicers prepared to arrest the suspect or guilty party confined within the building.

There is still a further feature, which consists of an alarm device and which is located either in the building or. on the outside, in a.

police station, said device being operated either automatically by the closing of the door, or by a secondary circuit controlled by other controlling means.

While the invention has been illustrated and will be'further described as especially applicable to stores, F iglires 7 to 11, inclus1ve, of the drawings illustrate an embodi -ment, rendering the idea applicable to the Fig. l is a schematic view of a gate-actu-'- ating device, illustrating the relative as- 'soclation of the parts and a diagrammatical plan of the wiring system;

Fig. 8 is a top plan view of Fig. 7; and

Figs. 9, 10 and 11 are detail views of the sprin -ac tuated holding ratchet. N

Re erring to the drawings in detail, '1 represents a closure for the entrance of a building, whichniay be either a swinging or sliding dooror gate. In the present embodiment, for the purpose of illustration, we have shown a sliding gate of the lazy tong Further, it is to be noticed that thea switch under the 'store counter, near the Fig. ,3 is a horizontal section of the same;

type, preferably constructed of metal.

While the gate is shown closed, under normal conditions it will be open and will assume a position in which the sections of the lazy tongs are folded to the left. The gate is of usual construction, having the neces-I sary frame 2, with a stationary upright member 3, the lazy tong sections 4 and the front piece 5, which moves, together with the frame piece 2 and the lazy tong sections, to and from' open and closed positions, the

'roller"6 being employed to conveniently,

effect the opening and closing. The gate is provided with-a. latch 7, the rearend of which having a notched portion 8 which engages a dog (not shown) in the latch housing 9 to retain the gate in open position. Secured to the doorframe, preferably at the upper right-hand corner,.is anactuating de- 'VICG 10, the details of which will be hereinafter described. Mounted 'at the top of the front piece 5 of the gate is a chain 11, WhlCh passes over a toothed gear (to be further described) mounted in the actuating devicelO,

thence downwardly through the door frame, preferably working in a recessed portion of the frame, such as '12, and on the end of which is carried a weight 13. With the gate in open position, the weight 13will of course be suspendedadjacent the actuating device 10, and will thus have a tendency to close the gate, but this will be overcome by means of thelatch 7 fastened within thelatch housing.9. While the alarm device, shown in the present instance as consisting of a bell 14, is shown active, it will be readily seen that when the gate is open the end of'the first.

lazy tong-section will bear against the push rod 16 of the automatic alarm operating means, and thus retain the

contact pieces

17 and 18 apart. Now, with the gate open and the parts so far described assuming the same-relative'position as described, the entrance to the building will be unobstructed.

.Should a robbery or any other disturbance occur' within the building which 'would -make it desirableto close the exits, the latch 7 will be actuated to permit theweight 13 to close the gate, and also permit the. spring 19 to close the

contacts

17 and 18 and actuate the automatic alarm device 1 1. The gate will thus be closed and retained in this position b means of the opposite end 20 of the latch engaging the eye 21, and the locking of the actuating device 10. With this accomplished, it will be necessary to electrifythe gate to prevent it being broken open. Therefore, a suitablesource of elec tricity, such as from the dynamo 22, is supplied to the gate through the posts-23 and 24, the circuit 25 for which being controlled by the switch 26, and the circuit for controlling the release of the gate toclosed position being 27, controlled by the switch 28. This circuit is completed by the switch and the latch housing 9. Upon the closing of the gate the-alarm'will automatically sound, as above described. However, to sound the same in a police station, a separate circuit .29, controlled by the switch 30, is provided.

i ergized, will release the end ofthe latch 7, J

When the alarm has been answered, the

charging circuit is out to the gate by opening switch 26 and the gate releasing means, consisting of the magnet 31, which,when enthe circuit 32 for which being controlled by switch 33, said circuit also having a shunt to the actuating device 10 in order thatthe toothed gear may be released to enable the gate to be pushed back.

bolt is adapted to slide in a guide Hsupported on'the frame E, and is provided on its opposite end with a pivoted catch I, adapted .to interlock with the pivoted spring-presse dog J. Thus, when the pivoted end I of the bolt is interlocked'with the'dog J, as shown in Fig. 5, the bolt is disengaged from the ratchet F and thew'eight 13 on the chain 11 is released. Normally, the bolt is out of en'- gagement with-the ratchet; that is, when the gate is open or in normal position, the means dss for controlling the bolt and the release of the ratchet consists of a pair of parallel electro-magnets K, which are also supported on the frame E, in position to actuate the armature L,- which is pivoted as at M, withits outer end acting as a lever or finger to engage a post on the bolt. The bolt is held in engagementwith the ratchet under tension of a spring N. Now, when the switch controlling the circuit to the magnets K is on,

the armature L will be actuated and draw the bolt away from the ratchet, overcoming the tendency of spring N; this functioning occurs when the controlling-switch 28 and the circuit 27 are closed, or when this switch- 28 is closed'to release the latch 7 from the housing 9. When it becomes desirable to release the gate to open position, the switch 33 is closed, whereupon the end 20 of the latch 7 will beraised and disengaged from the eye 21; at the same time, the short clrcuit 34 will energize the coil K and the armature L .will operate to draw the b0'1t G awayfrom the .ratchet.- The automatic alarm contact is represented by the spring tension lever O and its contact P. The magnets Q, the armature, R and the actuating means S, for the catch J, which means are actuated by the armature R, are employed to release the "bolt from the catch. The bolt G is provided with "means other than electrical, for throwing it into and out of engagement with the ratchet.

This means comprises the key T, which is, adapted to turn the spindle U, to which is attached a small chain V, the other end of which being secured to the post W.

The'forms. illustrated in Figs.- 7 to 11 are practically the same as the form just de-v fastened at one end to the door sill and at the other end on the drum B. This modified form does not require the electrical wiring, as the bolt may be released by the key T,

as in the firstform.
