COMBINED FLASH LIGHT AND UMBRELLA.

Application filed August 5, 1926. lSerialjo. 127,448..

T he object of this invention is to provide the handle of an umbrella with a flashlight., the casing of which is formed in sections, one of these sections carrying aA lamp and being movable angularly with reference to the handle and rod of the umbrella.

A further object is to provide a device of this character, which will permit the user to have full control of the flash-light without the necessity of handling `the umbrella and light separately.

A further object is to provide a two-part casing which will carry two cells, with means for` connecting the cells electrically, and maintaining connection, without interfering with the movement o'f one section relative to the other and to the handle, incident to the shifting of the light-beam in, t-he direction desired.

lith the foregoing and other objects in view, the invention consists in the novel construction and arrangement of elements described, illustrated and claimed, it being understood that modifica-tions may be made within the scope of the claims A'without departing from the spirit of the invention.

In the `drawings forming part of this application, 1

Figure 1 shows the two-part casing in vertical section, a portion of the rod ofthe umbrella being illustrated in the upper part of the View, and the Vangular movement of the lower section being illustrated in dot-ted lines. I

Figure 2 is a fragmentary view, constituting a sect-ion taken in a plane at a right angle to the plane in which the section of Figure 1 is taken.

Figure 3 is a section on line 3-3 of Fig ure 1.

Figure 4 is a section on line 4-4 of Fig ure 1.

Figure 5 is a section on line 5-5 of Figure 1.

Figure 6 is a view similar to Figure 5, but the contact fingers have moved away from the segments of insulation, into position for making electrica-l connection.

Figure 7 is a perspective view showing a battery made up of a number of individual cells, of small diameter, arranged in ythe manner illustrated.

The element 10 is intended to illustrate the rod of an umbrella, although it may be considered as representing-a cane, so far as the use of this particular form of'flash-light on any similar article is concerned.

The rod 10 enters a bore in the handle 11, and the latter is preferably of cylindrical form, the major portion thereof being tubular and providing a. chamber 12 in which 'a cell may be mounted. This tubular .portion of the handle constitutes one element of a battery casing, comprising two sections, each adapted to receive a battery cell. One side of the handle 11 is provided with an opening adapted to be closed by a door 13 having a notch 14 therein for engagement by the user when remving a cell, such as 15, for the purpose of inserting anew one. The dooris hinged at 16 and is held in closed position by a` slidable ring 17 adapted to engage the surface of handle 11 and the upper edge 'of the door. This element 17 constitutes a sleeve or collar.

The detachable end member 18, preferably of metal is provided with ears 19 and 20, spaced to receive therebetween the tongue 21 carried by end member 22 of the lower tubular member 23,' which may have threaded connection at 24 with element 22. The battery cell 25 mounted in section 23 of the casing is illust-rated in Figure 1 as having one terminal 26 in engagement with the central terminal of a lamp base, the lairn'p being shown conventionally at 27 and being received within a vsocket 28 carried by re- Viiector 29. A lens 30 is retained by a anged collar or the like designated 31. Y

The tongue 21, of diskv form extends between ears 19 and 20, of similaiferm, and a pin 33 constitutes a connecting element, passing thru outer disks 34, ears 19 and 20,

and tongue 21. Insulation is shown at 35 y and 36, serving an obvious purpose, when the electrical connections, referred to below, are considered.

A resilient element 38 is secured by a screw 39, and is in electrical connection with metallic strip 40 extending to the point 41. The central terminal 15 of cellI 15 is in contact with a brush or the like designated 42 adapted for electrical contact with tongue 21, so that electrical connection Will be maintained for the various positions which element 23 of the casing may assume when shifted by the user in order to throw the rays from lamp 27 in the direction desired.

Tongue 21 includes an extension 44 engaged by resilient fingers or the like designated 45, oppositely located, and suitabl'y mounted, for rotation with section 23 of the casing. By rotating this element 23 thru a quarter turn, the fingers are caused to contact either with the metallic element 44 or the insulated segments 46 of Fig. 6. The circuit is broken when the segments 46 kare thus engaged. Fingers 45 are in electrical contact with the end Vof cell 25 of the battery, and a metallic strip 48 extends thru end 22 of casing 23, and is insulated from said end, and extends thence to point 49 where it has electrical connection with reflector 29 and socket 28 receiving the lamp base 27. The end ot strip 48 is designed to engage one of t-he ears, land provide surface contact therewith at the point 48.

Current will pass from battery terminal thru brush 42 to tongue 21, thru extension or post 44, and if the casing 23 is in vposition for completing a circuit, as in Figure 6, connection will be established with the adjacent end of cell 25 thru fingers 45. Central terminal 26 of cell 25 is in contact with the central terminal of the lamp 27 and the exterior of the lamp base is in electrical connection with the socket 28, reector 29, and strip 48, at the end portion thereof designated 49. Strip 48 engages at 48 with one of the ears 19, 20, and the latter are carriedby end 18 ot casing section 13,-el'ement 18 being engaged by conducting strip 40, having electrical connection with the` end of cell 15. i

The connections permit the casing section 23to be rotated .thru a quarter turn to permit of the control of the circuit thru the construction of Figures 5 and 6, and the casing section 23 may be moved to dotted line w osition as in Figure 1 or ma be moved to any intermediate angle, s o that the user may throw the light beam in the desired direction. y

The cells employed may be of standard type, or may be of the type illustrated in Figure 7 wherein several individual cells 51 are grouped about a central' cell 52, all of these elements beingof small diameter, and being capable of renewal individually, in order to extend the life of the complete device, when separate portions become exhausted while others are still good and capable of use.

I-Iaving described claimed is l. In a device of the class described, a casing comprising two tubular sections, each 'section adapted to receive a battery cell, means for pivotally connecting the sections at :adjacent ends, a lamp carried by one scction of the casing, and means for Vconnecting the poles of cells adapted for reception within the casing, the connection for the cells extending across the pivoted connection of the invention what is the sections, and means to energize the lamp Y at'will from the battery.

2. In a device of the class described, a casing comprising two tubular sections, cach section Iadapted to receive a battery cell, -means for pivotally connecting the sections at adjacent ends, a lamp carried by one section of the casing, battery cells connected with the lamp andV positioned respectively within the sections of the casing, means for electrically connecting unlike poles of the cells and maintaining connection independent of relative movement of the sections of the casing, and means to energize the lamp-` at will from the battery.

3. In a device of the class described, ak casing comprising two tubular sections, each section adapted to receive a battery cell, longitudinal extensions on said sections, means for Vpivotally connecting the extensions, a lamp carried by one section of the casing, means for connecting the polos of cells adapted for reception within the casing, and ymeans to energize the lamp at will from the battery.

In testimony whereof I aliix my signature.

FRANK DAVID MALUM.
