HOMER KIMURA, OF GUNN, WYOMING.

ELECTRIC LAMP.

Application filed June 25.

To (171 whom it may concern:

Be it known that I, T'TOMER KIMURA, a citizen of the United States, residing at Gunn. in the county of Sweetwater and State of \Vyoming. have invented new and useful Improvements in Electric Lamps, of which the following is a specification.

This invention contemplates the provision of a portable electric lamp mounted upon a support for universal adjustment to permit the light rays to be thrown in any desired direction. and to also increase and decrease the area of illumination with a consequent variance of the intensity of the light as the occasion may require, together with means for holding the lamp fixed in adjusted position.

The nature and advantages of the invention will be better understood from the following detail description of the device, when considered in connection with the accompaying drawings wherein like numerals of reference indicate similar parts in the several views and wherein Figure 1 is a front elevation of a lamp constructed in accordance with my invention. Fig. 2 is a side view. Fig. 3 is a rear elevation. Fig. 4 is a top plan showing the lamps adjusted away from each other. Fig. 5 is a similar view showing a diiferent adjusted position of the lamps. Fig. 6 is a View of the same folded. Fig. 7 is a perspective view of one of the lamps removed. Fig. 8 1s a transverse sectional view therethrough. Fig. 9 is a detail view of the post. Fig. 10 is an enlarged detail view showing one manner of supporting the lamp.

Referring more particularly to the drawings 5 designates a post having a collar or shoulder 6 adjacent the lower end thereof, a pair of wings being indicated at 7 and 8 respectively. The wing 7 is formed to provide spaced knuckles 9, while the adjacent edge of the wing 8 terminates to provide an intermediate knuckle 10 disposed between and in line with the knuckles 9 for the reception of the post 5 adapted to be passed through the knuckles. 'By reason of this construction it will be noted that the wings are mounted upon the post for relati ve adjustment, or in other words are adapted to be moved toward and away from each other when desired, and held in any angular position by means of the button 11 adjustably mounted upon the upper end of the post 5 and adapted to bind the knuckles for Specification of Letters Patent.

the respective wings between the said buttons and the collar (3. Each of the wings has secured thereto in any suitable manner the lamp which may be of any particular type suitable for the purpose, but as shown in this particular instance includes a parabolic reflector 12 having arranged therein an electric bulb 13. the butt 14 of which is preferably threaded through a nipple 15 into a receptacle 16 threaded upon the nipple and including a contact plate 17 for engagement with the central contact 18 of the electric bulb. The enlarged end of the reflector is closed by the lens 19 which is held associated with the reflector in any suitable manner.

20 indicates a handle for the lamp adapted to be associated with the post 5 to permit the lamp to be conveniently handled as Well as to permit the same to be carried from place to place. The handle may be associated with the post in any suitable man-- ner preferably'by means of a lug 21 arranged at one end of the handle, and a yoke 22 arranged upon the lower end of the post 5 and which may form an integral part thereof. The lug 21 is adapted to be passed between the parallel portions of the yoke, and provided with a central opening adapted to register with alined openings in the said parallel members of the yoke, and through which ispassed a bolt 23 and held associated therewith by means of a thumb nut 24. lvlanifestly this construction provides for an adjustment between the handle and the lamps, to permit the lamps as a unit to be moved forwardly or rearwardly to different angular positions with respect to the handle and held in this position by means of the thumb nut 24. This adjustment together with the relative adjustment between the lamps provides what may be termed a universal adjustment to permit the lamps to be adjusted independently or simultaneously to almost any position as the occasion may require.

The device in its entirety may be used as an automobile trouble lamp, although it is susceptible to an unlimited number of uses, and for the purpose of suspending the lamp when desired, from a suitable support I employ a hook-like element 25 terminating to provide an eye 26 embracing the shank of a headed bolt 27 which latter is passed transversely through a suitable opening in the handle and held associated therewith by means of a thumb nut 28. The bolt is provided with a squared portion 29, which n...

tion is embraced by the eye 26 to prevent casual rotation of the hook element, subsequent to being moved to adjusted position. It will be manifest by reason of this construction that the hook element may be swung to any angular position with relation to thehandle, to permit the lamp to be suspended or mounted upon almost any form of support, and if necessary the lamp subsequently adiusted to the proper position with a view of throwing the light upon the work. The adjustment of the hook elementis obtained by merely loosening the thumb nut 28 and rotating the bolt 27 together with the hook until the latter is forced to assume the proper position, and of course held in this position by tightening the thumb nut 28. Should it be desired to support the lamp vertically upon a table, working bench or other horizontal support, the hook element 26 is removed from the handle, and the latter arranged between the parallel members 30 of a substantially U- haped bracket 31 secured in any suitable manner upon the base 32, so that the transverse opening in the handle will be disposed in a line with the openings in the parallel members 30, and through which openings the bolts 27 is adapted to be passed and upon the free end of which the thumb nut 28 is mounted for the purpose of holding the parts operatively associated in the manner shown in Fig. 10.

A pair of conducting wires 33 have one end connected with a battery (not shown) or other suitable source of energy, and their opposite end connected with the binding post 34: mounted upon the wings 8 and 9 respectively. One of the wires is ground upon the wing 7, while the other wire is insulated and terminates to provide the branches 35 leading to the lamps and connected with the receptacles 16 of the respective lamps in any suitable manner. One of the branches is threaded through suitable eyes 36 to hold the branch in proper position so that the same will not interfere with the adjustment of the lamps toward and away from each other. A suitable form of switch 37 is connected with one of the wires, and mounted upon the handle 20 for opening and closing the circuit of the lamps.

It will be obvious from the foregoing description, that the lamps may be adjusted in any direction the occasion may require, the lamps when adjusted in the manner shown in Fig. 4 increasing the area of illumination, and when moved toward each other as shown in Fig. 5 the area of illumination is not only decreased, but the intensity of the light is proportionally varied with re gard to the degree of adjustment of the lamps toward and away from each other.

' It will be further noted that the lamps may be folded in the manner shown in Fig. 6 so as to reduce the size of the article for transportation, as well as to protect the lens 19 from being broken. For the purpose of transportation the lamps together With the post 5 may be removed from the handle 20 by reason of the connection between these parts to permit the various parts to be conveniently packed as will be readily understood.

It is believed that from the foregoing description the nature and advantages of the invention will be readily apparent without requiring a more extended explanation. However, I desire to have it understood that I do not limit myself to the precise construction and arrangement of parts herein illustrated and described, as various changes in this respect may be resorted to when desired as fallv within the scope of the appended claims.
