ANTIHOLDU-P DEVICE.

Application flled ltarch 8, 1926. Serial No. 92,095.

This invention relates to a device affording protection from burglars, and has for its object the provision of an armor plate which may be automatically inserted between the burglar, and the protected, upon the closing of an electric switch by the latter.

Customarily, burglars, and hold-up men upon entering a store, such as a 'ewelry store, are in front of the counter, while the clerk is stationed behind the counter. The hold-up man may draw a gun, and command the clerk to put his hands up, and threaten to shoot. The clerk raises his hands, and at the same time steps on a switch, whereupon an armorplate swiftly moves up from the .counter, and shields the clerk from the bandits gun.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description, and accompanying drawings, and to the appended claims in-which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawing shows a fragmentary rear elevational view of a counter with the invention embodied thereto.

'Fig. 2 shows a sidev elevational view taken on the line 2-2 of Fig. 1.

Fig. 3 shows a fragmentary horizontal sectional view taken on the line 3--3 of sectional view taken on the line 44 of Fig. 2. v

Fig. 5 shows a fragmentarv rear elevational view of a wall with a door, and the invention embodied thereto.

Fig. 6 shows a fragmentary portion of the device, illustrating to an enlarged scale the armor releasin mechanism.

Fig. 8 shows a fragmentary sectional view taken on the line 8-8 of Fig. 9.

Fig. 9 shows on an enlar d scale, a fragmentary portion of the indicating device, as seen on a small scale in Fig. 3.

Fig. 10, shows a fragmentary sectional view of a glass window to which the invention may be applied.

Referring to the drawing, the numeral 12 indicates, generally a counter which: ma

have a dis lay case 12' on the top thereo and behin which a clerk stands when atwith gear 28, of a train of ears cilitate entrance to the rear ofithe counter,

the armor plates 13, and. 16 are constructed with slidable doors 17. Springs 18 extend withinthe channels 14, and have their upper ends fastened to the ceiling 15, and the lower ends to the bottom of the movable armor plate 16, normally tending to snap the said armor plate upwards to the ceilin and thus separate the clerk in back of the counter from a bandit in front. To shield the clerk from the sides, door armor plates 19 are hingedly connected, as at 20, to the front armor plate 16, and while the plate 16 is in a lower position the said doorsare closable to allow assage behind the counter, but'the outer e ges of the doors are engageable in guides 21, having alower open side 21, and fastened to the store wall 22, extending from the floor to the ceiling, so that in the raised position the door plates are rigidly held. The lock 23 automatically locks the armor in the upward posi tion, to prevent manual pushin down of the armor from the front of the counter. Support 24 from the plate 16, carries a pair of contacts 25, aligned with ceiling contacts 26, so that an electric circuit to an exterior alarm will be complete when the armor plate 16 is in the raised position.

The device isprovided with means to normally retain the armor plate 16 in lowered position, and manually controlled means to release the holding means, and allow the springs 18 to raise'the plate. The plate 16, on the exterior of the forked portion 16%, being provided with rack teeth 27 meshable supported by shafts journaled in the 0d plates 29, supported from a stationary pa of the rear of counter 12. The last ofthe train of gears has. an escapement wheel 30 fixed to its shaft, and en aged by an escapenlent arm 31, operated y an electrom net 32, controlled by a switch operated y the clerk' behind the counter by stepping on the switch board 33, which has the necessary wires 34 leading to the electromagnet. Stepping on the switch board 33 will not result in an imgears 38 to a rack 39 integral with the forked portion of armor plate 16. The clerk suspecting a customer as being ahold-up man, may with his foot tap the switch bar 33 until the indicator shows that the" armor plate will be released upon the next tap.

The modification shown in Fig. 5 illustrates the device mounted above a door 40,

to entrap the burglar. The slidable armor plate 16', has the necessary co-acting spring 18', the alarm connections and 26, the electroma not release 32, and the indicator 35. In ig.1(l, a window of glass, may be formed oi two plates 42, and 43 allowing a central passa e 44: for the armor plate, so as to cut ofii' t e window as an escaping medium for a bur lar,

While l have illustrated and described my invention with some degree of particularity,

l realize that in practice various alterations therein may be made, ll therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the. correlated parts without departing from the spirit or the scope of the ap derided claims.

Having thus descri ed my invention, what I claim as new, and desire to secure by United States Letters Patent is:

1., A. device of the class described, comprising an. armor plate in a hidden position. springs to project the said plate to a shieldingposition, means for normally retaining said armor plate inthe hidden position, escapement mechanism for permitting a partial )rojection of said-armor plate to position t e same in readiness for sister complete projection, manually controlled means for controllin said escapement mechanism and tor re easing the said retaining means, and indicating 'means for disclosing the position of the partial progection of said armor late,

2. A device (if t c class described, comguides extending mm the said hidden position, springs to project the said plate to a shielding position determined by said guides, means for normally retaining said armor plate in the hidden position, inanually controlled means to release the said retaining means, an alarm connectiomiclosed when said armor plate is in the shielding position, and indicating means informing the position of the said releasing means,

4. The combination, in a devie oi the class described, of an armor plate havin A rack teeth on a face thereof, engageable with a gear from a train of ears, the last gear of said train of gears being fixed to a shaft provided with an escapement wheel, engaged by an escapement arm, controlled by an electroma et, operated by a manual switch, where y said armor plate may be retained in position, or manually released by the operation of said switch,

5. The combination, in a device of the class described, of an armor plate having rack teeth on a face thereof, engageable with a gear froma train of gears, the last of said train of gears being fixed to a shaft I provided with an indicating wheel, whose indications may be observed through a window, in a casing housing said wheel. whereby the relative positions of the said armor p ate in respect to a holding, and releasing device, ma be known,

In testimony whereof I have aflixed my signature,
