UNITED STATES PATENT'OFFICE.
WILLIAM R. CRAIG AND JAMES H. CRAIG, OF CHICAGO, ILLINOIS.
MECHANCS TROUBLE LAMP.
Application filed Eebmary 10, 1923. Serial No. 618,228.
T0 aZZ w7w;m z't may concem:
Be it known that we, WILLIAM R. CRAIG and JAMES H. CRAIG, both citizens of the United States, and both residing at Chi cago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Mechanics Trouble Lamps; and We do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.
Our invention relates to lighting appliances and in some of its general objects aims to provide an inexpensive, easily manufactured and eflicient lamp-socket and refiector arrangement in 'combination with simple and adjustable means for attaching such an arrangement to the head of the user and for afi'ording the electrical connections t0 a source of current.
In its immediate commercial aspects, our invention is particularly suitable for use in place of the ordinary trouble lamps durlng the inspection and repair of automobiles, as its attachment to the head of the user leaves him the free use of both bande. Furthermore, the light-reflecting portions of our appliance are so designed that the refiected light Wlll issue mainly in a forwardly and dovmwardly sloping direction corresponding to the usual line of vision of the person to whose head the appliance is attached, thereby insuring the effective concentration of a large share of the light in the direction in which the user is lookirig.
Further and also more detailed objecte of our invention Will readily appear from the following specification and from the accompanying drawings, in which Fig. 1 is a perspective view of a mechanics head lamp or trouble lamp embodying our invention.
Fig. 2 is an enlarged front elevation of the same with portions of the head-encircling strap broken away.
Fig. 3 is a vertical section taken transversely of Fig. 2 along the line 33 of that figure.
Fig. 4 is a plan view corresponding to the elevation of Fig. 2 and also showing only a portion of the head-encircling band.
In the embodiment of the drawings, the appliance of our invention comprises an adjustable etrap or band adapted to be attached to the -oead of the wearer (with a portion of the band bearing against his forehead), a forwardly opened casing attached to the forward part of the said band; a pair of lamp-sockets carried by the casing and supporting lamps within the latter, the casing having interior reflecting surfaces arranged for redirecting a considerable portion of the light of the lamps in desired directions; and conductors for supplying current to the lamps.
Thus, Fig. 1 shows a band 1 in the form of a flexible ring, including an elastic or otherwise adjustable portion 2, and includ ing overlapping tabs 3 and 4 equipped with cooperating snap fastener portions 5 and adapted to clamp portions of a flexible lamp cord 6 to the main band portion 1. The wires of this-flexible cord extend partly across the frontal portion of the band and lead to the usual conducting elements of a pair of lamp sockets 7. These sockets e tend respectively through the opposite ends 8 and 9 of a metal casing which has its back 10 secured to the band 1 and which desirably has its ends 8 and 9 divtarging forwardly toWards the mouth of the casing as sh0Wn in the drawings.
The casing also desirably has its 'bottom 11 sloping downwardly and has its top 12 s0 curved that this top Will cause a downward refiecting of light from a pair of lampe 13 respectively carried by the two lamp sockets 7. That is to say, this top 12 desirably is so shaped that light reaching its forward portions from the lamp filaments Wlll be reflected forwardly and clownwardly as shown by the dotted line 14: of Fig. 3, While rays of light from the lamp striking the upper portion of the back 10 of the casing and refiected by this back against the top 12 Will thon be refiected by the latter in a forward and downward di rection after the manner shown in the dotted line 15 of Fig. 3. At the same time, raye of light striking the forward portion of the bottom 11 of the casing Will be refiected forwardly after the manner shown by the dotted line 16 of Fig. 3.
With the reflecting casing thus constructed, it Will be obvious from Fig. 3 that when the user has his head erect, the forwardly directed rays of light from the lamp are unobstructed; that the back of the reflector Will redirect a good share of the rearward rays of light from the lamp so as also to project these forwardly; and that the bot-
