1927, Serial No. 14,777, led Harch 11, 1925. Application for reissue led August 18, 1928. Serial No. 300,555.

The present invention relates to improvements in lamps; and has particular reference to a lamp intended to be secured to a person without interfering with the use of his hands. A lamp of this character is particularly useful for miners who may secure the same to the hat or cap, or their clothes, but it is also convenient in many other situations as, for instance, to a physician who wishes to closely inspect throat or eyes, or other portions of the body of a patient and who may secure the lamp to the front of his head so that the rays of the light naturally fall upon the place to be inspected Without requiring the use of the hands.

A particular feature of my lamp is that it represents a flat base so that it may be set on a table; that it presents a shaped rear wall fitting preferably on that part of the human body or other object to which it is intended to be attached, and a slanting light opening to which a reflector is hinged in such a manner that the reflector opening may be moved from a forwardly slanting position into a horizontal position While means are provided for automatically holding the refiector in any position to which it may be advanced.

Further objects and advantages of my device will appear as the specification proceeds.

The preferred forms of my invention are illustrated in the accompanying drawing, in which- Figure 1 shows a front view of my lamp.

Figure 2 a vertical longitudinal section through the same.

Figure 3 a sectional III- III of Figure 2.

Figure 4 a fragmentary horizontal section showing a slightly modified form, and

Figure 5 a detail sectional view through a portion of the housing and a portion of the reflector.

While I have shown only the referred forms of the invention, it s ould e understood that various changes or modifications view taken along line may be made within the scope of the claims hereto attached without departing from the spirit of the invention.

My lamp comprises in its principal features the light housing 1 of a reflector 2. The light housing 1 includes a flat base 3, a rear wall 4 which may be straight, as illustrated in Figure 2, or which may be curved to fit the outlines of the object the lamp is to be secured to, as illustrated in Figure 4, and a light opening 6 which slants forwardly from bottom to top preferably at an angle of about to the base line.

The side wall of the housing is preferably made cylindrical except for the flat base and the overhanging portion 7 caused by the slanting light opening is curved along the top, as illustrated in Figure 2, to provide an are of which the lower edge of the light opening is approximately the center. The Nlight housing has ears 8 extending laterally from the rear wall thereof, the ears serving as attaching means for a band 9 by means of vwhich the light housing may be secured to an object such as a hat, ca or the like. Another ear 11 extends from the top of the rear wall to receive aY hook 12 by means of which the light may besuspended from a belt or similar object.

The reflector 2 which may be of any suitable form and which supports a light 13 on the inside thereof is hinged to the lower edge of the light opening, as shown at 14, and is provided with a flange 16 adapted to lie against the edge of the light opening. A collar 17 extends forwardly from the flange 16 and is adapt-ed for reception of the lens 18 which is held in position by the ring 19 adapted to be threaded upon the collar 17. The reflector which is of smaller proportions than the light housing has a hood 21 secured to it near the fiange 16 thereof, the hood being formed to run parallel to the projectin portion of the light housing and 1n space relation thereto so that the Oufi face of the hood is adapted to ride on an internal flange 22 formed in the light housing at the opening thereof; while at the same time an external flange 23 at the rear end of the hood 5' is in sliding contact with the inner face of the projecting portion of the light housing, the hood being made to exert spring tension against the light housing and to hold the reflector in any position to which it may be advanced manually.

The advantages of my lamp will be readily understood from the foregoing description.

The lamp may be set on a table without any further support and will securely rest on the base 3. The lamp may be suspended from a belt or may be secured to a hat or any other suitable object by means of the band 9. Whatever support is selected for the lamp, the reflector' may at anytime be moved from the forward slanting poistion, illustrated in full lines in Figure 2, to the dotted line position or to any intermediate position, and will be firmly held in any desired position by the hood 2l which at the same time serves as a protector for the reflector when the same is projected from the light housing. The light moves with the reflector and the light rays may be thrown in any direction desired within the range of the turning movement of the reflector.

It might be mentioned in this connection that in addition to the uses mentioned in the first paragraph of the description many other uses will be found for my lamp; the lamp would, for instance render excellent service as a reading lamp if attached to the front of the head or might be secured to the back of the hand or wrist of an automobile driver to serve as a signalling device. When used as a reading lamp, a suitable colored lens might be selected to minimize or eliminate the relection of light rays into the eyes.

1 claim:

l. A miners lamp comprising a housing having an opening inthe front thereof, the upper forward part of said housing curving downwardly as it extends forwardly, said upper part extending forwardly of the base of the housing, a reiector set in said housing,

said reflector being hinged at its lower forward edge to the lower forward edge of the base of the housing and closing the opening in said housing, and a hood Vsecured to the top of the reflector, said hood pressing resiliently against said housing whereby it will maintain the reflector in a desired position relative to the housing.

2. A device of the class described comprisy ing a substantially cylindrical housing having a fiat base portion and its wall above the base portion extended `on a downwardly curved arc beyond the forward side of the base portionto provide an opening at an angle approximating the radius of the are,

a reflector within the opening of said housing JOSEPH F. N ENZEL.
