ERNEST A. HAVENS, OF 'IPEORIA, ILLINOIS.
PoRTABLE'ELEcTRIo LAMP.
Application filed November 19, 1923. Serial No. 675,553.
This invention has reference to portable electric lamps and it has for ts principal object to provide a lamp of the character provide in a portable lamp, ahandle, lever actuated jaws for clamping the lamp to a support, a flexible tube carrying a bulb or lamp, an open wire guard surrounding said bulb or lamp, a revoluble reflector Within the guard and means arranged exteriorly of the guard for adjusting and holding the reflector in adjusted positions. The, arrangement of the elements being such that the lamp may be clamped to any desirable object, the flexible tube bent or turned to position the bulb on the object to be lighted and the reflector adjusted to project the light on the desired object and to shade the eyes of the person using the lamp.
A still further object of the inventionis surrounded byan open wire guard, the reflector being located between thebulb and guard, and in the provision of a reflector turning knob disposed exteriorlv of 'the connected to the reflector, whereby on the turning of the knob the reflector may be positioned in different positions around the bulb.
That the invention may be more fully understood, reference is had to theaccompanying drawings forming a part of the present description, illustrating a preferred embodiment of the invention, in which Figure 1 is a side elevation of my improved portable electric lamp ona somewhat reduced scale, the same being shown clamped to asuitable support, and in dotted lines illustrating how the flexible tube may be bent to place the bulb or lamp in. different positions;
Figure 2 is a detail end elevation of the open wire guard and reflector, the latter partly in section, and
Figure 3 is a detail in section showing the connection of reflector actuating knob to the reflector and journal bearing for same in the guard.
Like characters of reference denote cor responding parts throughout the figures.

'to a light socket.
to provide a revoluble reflector for a bulb] guard in axial alignment with the bulb and '1 designates a handle, the main body portion of which is preferably of channel format-ion .for lightness. One end is bifurcated and formed ,or provlded with flat bearing plates 2, between which and to.
which are pivoted clamping jaws 3. To the opposite end of said handle is suitably connected a flexible tube4 of well "known construction, to the outer end of which. is connected a light socket '5. which is carried within the tube t and connected to the light socket enters the handle intermediate its ends, preferably at 7 through a bushing 8 or other suitable con- Said cord being of adesirable length and supplied with the usual and ordinary connections for attaching the same connected the usual bulb or lamp 9 and clamped to said light socket and surrounding said bulb or lamp is the usual open wire guard 1().
Wires formingthe guard are connected has ournaled therein the short rod'12' the inner end ofwhich is connected to a sen' i-globular reflector plate 13 lying between the to be gripped by a person when it is desired to revolve and position the reflector. Surrounding the rod '12 between the knob 14: and the head plate 11 is a spring 15 which holds the reflector againstthe head plate, as shown in Figure 3, against vibration and when adjusted in diflerent positions. The value of the revoluble reflector and the actuating means therefor exteriorly of the guard surrounding the globe or lamp, it is believed will be readily understood. Guards are universally used on electric lamps in and about a garage, machine shop and the like, and reflectors are verydesirable and in fact essential Where lamps are used in machine shops and like places and are more desirable when the lamp is portable and adjustable. In the present disclosure the lamp be-s ing carried on a flexible tube it is very readily seen that an adjustable reflector is desirable, but so far as I am aware no one has provided a revoluble reflector within a' guard with means for turningv the reflector insane.
A. light cord 6 To the light socket 5 is I The lamp and guard are not unlike those now in general use, except that the head plate 11 ofith'e guard to which the I Hi l exteriorly of the guard, while at the 'same' time providing for 'holdingth'e reflector in adjusted positions; lVith such an arrange VID EIlt the scope of use of such a lamp 'is erably provided With plates l6't'o Which'are' attached cushions 18 preferably of: suitable soft rubber. p
The jaws 3 are adapted to .be brought into clamping position by means of a lever 21, the head of Whichis fulcrumed'betvveen'and to the plates 2 of the handle 1. The disposition of the'clamping ends of the jaws is such that as theyare' brought-into clamping position they will engage the object beginning' at their forward ends. In this Way, a better grip may be had on the supporting object. rubber, as the clamping element, the jaws may be brought into clamping engagement with a supporting object and pressure applied to cause the gripping suri'aces -of'the aws to more firmly implnge on the article and insure holding against any vibration, in the event the lamp is clamped to a vibrating part. 7
From the foregoing description it Will'be apparent that I have devised a portable electric lamp adaptable to many and various uses, and as disclosed is capable ot' many modifications, and I do not Wish to Further b rovidin ia cushion of a J7 a said bulb,- of"a revoluble reflector shade for said bulb mounted Within said guard, means arrangedexterior-1y of'the guard and connected vi-th said shade for turning the shade, and yielding means for holding the shade against vibration and in adjusted positions.
2. In a device of the character described, in combination, an open Wire guard for electric lights, a reflector shade rotatably mounted within said guard, and'means arranged eXte'riorly of the guard] and connected to'sai'd shade for rotating the latter.
3' An open Wire guard having a head plate to which one end of'the Wires or 'the guard are connected, a reflector Within the guard, anda shaft'journaled in the head plate and fixedly secured to and constitut ing the sole means of support for the rcfl ector, said shaft'projecting through the head plate to be manipulated from Withcut the guard.
at. A guard for electric lights, having a head plate, a reflector adjustable Within the guard, a shaft fixed to the reflector and journaled in the head plate, and means arranged exteriorly of the guard for adjustably securing the shaft and reflector in an adjusted position;
In WitIlGSS whereof, I have hereunto atfixed my hand this 16th day of Novembu; 1923. i l
