TRICK ELECTRIC POCKET-LAMP.

Specification of Letters Patent.

Patented Apr. 12, 1910.

Application filed October 7, 1909. Serial No. 521,434.

To all it may concern:

Be it known that I, AARON JEDEL, a citizen of the Unlted States, and a resident of the city of New York,'borough of Manhattan, in the county and State of New York, have invented a new and Improved Trick Electric Pocket-Lamp, of which the followmg 1s afull, clear, and exact description.

Th1s invention relates to certain improvements in trick apparatus, and more particularly to that type of apparatus in which a movable part may be unexpectedly released during the handling or'manipulating of the device.

One object of my invention is to construct the device so that it will have the enact appearance of a pocket electric light with the battery casing, light bulb and switch or push button. Instead of providing the interior of the battery casing with a bat,

tery and with connection to the bulb, I provide an extensible member, so mounted that when the switch or push button is operated to turn on the light, the extensible member will be released and a-portion of the device will be projected outwardly to the consternation of the person who pressed the button with the expectation of closing an electric circuit and turning on the light. The general combination of elements may be em bodied in other forms than in a pocket electric light, without departing from thespirit of my invention, and certain of the structural details are of importance for use in other types of apparatus of the same general character.

Referen'cejs to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding-parts in all the figures, and in which- Figure 1 is a perspective view of a device constructed in accordance with my invention, a portion of the outer casing being broken away and the parts being in operative position; Fig. 2 is alongitudinal section through the device, the parts being. shown in extended or discharged position; and Fig. 3 is a transverse section on the line 33 of Fig. 1.

In the specific form of apparatus illus- 'trated, I employ a cylindrical casing .10,

substantially in the form of a metal tube and having an outer coating to make the easing simulate, as near as possible, the battery casing of a small pocket electric light. The

ends of the casing are closed by caps 11 and 12, one of which, 11, is permanently secured in place and the other of which, 12,.is detachable from the casing. lVithin the cusing is a coil spring 13, one end of which may be soldered or secured in any other suitable manner tothe cap 11 or to the lower or innermost'portion ofthe casing. I At the outer end of the coil spring is a head let of any suitable material, for instance, wood, and,

permanently secured to the outer or free end of the coil spring-13. The outer end of this head is secured to the cap 12 and is provided with a cavity or recess 15 in its outer' end and opposite to an opening through the cap. A glass bulb or knob 16 is provided with a stem 17, which extends through the opening in the cap 12 and into the cavity or recess 15 in the outer end of the head 14. The glass stem 1'1 is glued in the recess and the bulb serves to hold the cap .and head together. The bulb or knob 16 is made to simulate. as near as possible, a small electric light bulb, and is preferably hollow, although if made solid, its solidity would not be noticed at first glance. The coil spring is of such strength that when released it will project the head, cap and bulb outwardly from the end of the casing a considerable distance, but as all of the parts are secured together, none of them can become detached or lost.

-For normally holding the spring in its compressed state and with the cap 12 in engagement with the end of the casing, the casing is provided with an opening 18 in one side thereof adjacent the cap, and the head is cut away at one side to provide a fiat surface 19. Secured 'to this surface is a spring 20, terminating at its free end in a knob or push button 21, which may extend out through the opening 18 and prevent longitudinal movement of the head. This knob 21 has the same general form and appearance as the push button on a circuit-closing switch of an ordinary pocket electric light.

With the parts assembled and'the coil spring under compression, the head and coil spring are entirely concealed from view and the cap 12 is'in engagement. with the end of the casing. The parts are all held in their proper relationship by the knob 21. If the device be handed to aperson unfamiliar with its construction, he assumes of course that it is a pocket electric light, and will almost instinctively press the button 21 in order to see the light. The pressing, of the button releases the coil spring 13 and the head light and ca are projected outwardly to the position in icated in Fig. 2 This, of course, is a great surprise to the person operating thesame and causes amusement to the onlookers. v

Various changes may be made in the construction and arrangement of parts within the terms of the appended claims, without departing from the S00 of my invention.

Having thus descri d my invention, I claim as new and desire to secure by Letters Patent: I

1. An imitation pocket electric lamp, comprising a casing, a cover normally closing one end of said casing, a head within the casing and terminating adjacent said cover, a glass bulb upon the outer surface of said cover and having a stem extending throu h the cover into said head tosecure the bul cover and head together, a coil spring within the casing and attached to said head and normally tending to project the latter outwardly from the casing, and a spring catch carried by the head and having a portion normally extending into an opening in the wall of the casing, to hold the first mentioned spring under compression.

2. In combination, a tubular casing, a cap normally closing one end thereof and havin an opemn therethrough, a head within sai casing an secured to said cap and havin a recess in its outer end, a glass bulb outside of said cap and having a stem extending through the openin in the cap into the recess in the head an secured within said recess, a coil spring within said casing and secured to said head for projecting outwardly the latter together with the cap and bulb, and a spring secured to the side of said head and having a knob extending outwardly through an opening in the casing and normally holding the first mentioned spring under compression, the s ring bein released upon the pressing inwar 1y of said knob.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
