ILLUMINATING DEVICE.

Application filed may 28, 1917. Serial No. 171,370.

One of the objects of the invention is to provide an illuminating device of simple and compact construction, which may be conveniently positioned within an obscurely lighted space to concentrate light at any particular desired local position. A further object is to provide a device of this type which may be placed contiguous to a door,

cover, or other closure, and having means whereby it may be operated by said closure, or independently thereof, at will. A further device is to provide a portable device of the character mentioned, which is particularly applicable for use in the cabinets of sound reproducing machines, .to illuminate the record, the stylus, and the record controlling devices, and which may be placed in position in any of the cabinets now in general use, without cutting or marring the same, or altering the positions of any of the parts.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawing Figure 1 is a perspective view illustrating the invention. Fig. 2 is a rear view, with the back plate or door removed and the battery shown in dotted lines. Fig. 3 is a transverse section on the line 3-3, Fig. 2. Fig. 4 is a similar section on the line 4-4, Fig. 2. Fig. 5 is a detail view of the detachable swltch-operating arm.

Referring to the drawing, 10 designates a casing of any desired shape, provided with a removable back plate or a door, 11, it being preferred to construct the casing of metal, although the invention is not limited in this particular. The front wall of the casing is provided with an opening 12, and concentric therewith is a reflector 13, provided with a lamp socket 14, in which is mounted an incandescent lamp 15, said socket having circuit with said contacts.

a base contact 16 electrically connected with one terminal of the lamp, the other terminal of the lamp being grounded through the casing.

Located at the ends of the casing are insulated supports 17, 18, the battery 19, of the usual dry cell type, being located between said supports. Attached to the support 17, is an end contact plate 20, provided with an angularly disposed resilient arm 21, overhanging the battery, and having an enlargement 22, which is pressed into contact with the base contact 16, by the resiliency of said arm. Attached to the support 18, is

a spiral contact spring 23, one end of which 1 bears against the base of the battery '19, the

other end of the spring being bent to form an overhanging contact arm 24. Attached to the top of the case 10, is a spring contact arm 25, preferably constructed of flat resilient metal, so shaped that the resiliency thereof will hold its free end upwardly in contact with the contact arm 24. Thetop of the casing 10 is provided with a slot 27, immediately above and parallel with the contact arm 25, and working in said slot is the shank of a slidable button 26, the lower end of said shank being provided with a protuberance 28 frictionally engaging the contact arm. By shifting the button 26, along said slot, the circuit is closed or broken, as

the case may be, by movement of the free end of contact arm 25 with respect to contact arm 24. Should it be desired to have the circuit broken automatically by means of a door or other closure, the contact 25 may be made of sufficient length to project through an opening in the back plate 11, and an angular operating arm 29, may be attached thereto, said arm having a socket to receive the end of said contact.

In operation, the battery 19 is placed between the contact spring 23 and the contact plate 21, being held in position by the resiliency of said spring, with its poles in The circuit may be-opened or closed, as previously stated, by movement of the button 26. When closed, the circuit is from the battery 19, through contact plate 20, arm 21 and enlargement 22, to the lamp and after passing through the latter, is grounded through the casing, passing through'contact arm 25, and contact arm 24 and spring 23,to the battery. Should the arm 29 be employed, the closing of a door, such as the cover of the cabinet of a sound reproducing machine, will bring said door into engagement with the angular portion of said arm, causing the same to pull contact arm 25 out of engagement with the contact arm 24, so that the circuit is broken while the door is closed, and illumination is not needed. As soon as the door is opened sufficiently, the resiliency of the contact arm will immediately bring the same into engagement with the contact arm 24, and close the circuit. Thus it will be seen that the circuit may be closed manually through button 26, or automatically by means of arm 29.

Having thus explained the nature of the invention, and described an operative manner of constructing and using the same, although Without attempting to set forth all of the forms in which it may be made, or all of the forms of its use, What is claimed is 1. An illuminating device of the character described comprising a casing, a battery supported in said casing in a normally horizontal position, a lamp above said battery, a battery retaining device engaging one end of'said battery and having an overhanging contact arm, means for placing one terminal 'of said lamp in circuit With the other end of the battery, the other terminal of the lamp being grounded through the casing, and a switch arm attached to the casing and positioned to engage said contact arm.

2. An illuminatingdevice of the character described comprising a casing, a battery supported in said casing in a normally horizontal position, a lamp above said battery, a battery retaining device engaging one end of said battery and having an overhanging contact arm, a flexible contact arm connecting one terminal of the lamp with the other MB end of the battery, the other terminal of tached to the casing trically connected the lamp being grounded through the easing, and a switch arm attached to the casing and positioned to engage said contact arm.

3. An illuminating device of the character described. comprising a casing, insulated supports at the ends of said casing, a flexible contact arm attached to one of said supports, a battery retaining device'attached to the other support and havingan offset overhanging portion forming a contact arm, a battery engaging said flexible contact arm and said battery retaining device, a lamp supported by said casing and having one terminal in circuit with said flexible contact arm and the other terminal grounded through said casing, and a switch arm atand positioned to engage said contact arm.

4:. An illuminating device of the character described comprising a casing, a lamp supported therein and having one terminal grounded through said casing, a battery in circuit with the other terminal of said lamp, a retaining device for the battery in circuit With said battery, said retaining device having a terminal contact, a contact arm elec- With said casing. and--10- cated contiguous to said terminal contact, means for effecting relative movement of said contact arm and said terminal contact, and an offset operating arm detachably connected With said contact arm.

In testimony whereof I have hereunto set my hand in presence of two. subscribirig Witnesses.
