A T TOfF/VE JOHN NEWTON, OF NEW YORK, N. Y.

PORTABLE LIGHT.

Specification of Letters Patent.

Patented Nov. 4, 1919..

A pplication filed January 10, 1918. Serial No. 211,309.

To all whom it may concern Be it known that I, JOHN D. Nmv'ron, a citizen'of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Portable Lights, of which the following is a specification.

My invention relates to certain new and useful improvements in portable lights and especially to those comprising a reflector for cluster lights, and a guard therefor. The chief objects of my invention are to provide a li ht of this character which will be exceedingly cheap to manufacture, easy to assemble, strong and durable in use and effective in operation, and one wherein the guard may be mounted on the reflector in a most satisfactory manner, this mounting being for the purpose of retaining the guard in position for protecting the lamps or for allowing ready access to the lamps by swinging the guard upon my improved mounting as a hinge.

An object of the invention is to provide a guard having lateral extensions engaging openings in the edge of the reflector where by the guard -may be readily adjusted in position, and whereby the guard may readily be swun 'out of position to allow the light bulbs toie inserted in the light cluster.

Novel means have been provided also to I lock the guard securely in position.

It will be apparent from the following description that the structure hereinafter described possesses many advantages over those now in the art, in that the cost of manufacture is reduced considerably and all the parts may be readily placed in position without the use of skilled labor, or any special tools.

In the accompanying drawings,

Figure 1 is a sectional elevational View;

Fig. 2 is a perspective;

Fig. 3 is a fragmentary plan View of the top of the reflector showing the bail held in place by the retaining means for the light. cluster Fig. 4 is a detail of the retaining means for the guard, and I Fig. 5 is a sectional view of a modification of the locking me ans for the guard;

Fig. 6 is an elevational view showing the portable light in a hang ng pos tion with the guard in the position it IS retained when opened;

Fig. 7 is an enlarged view showing the extension ,from the guard in the hole of the reflector as they are when the guard is opened in the position in Fig. 6.

Referring to the drawings in detail, 1 designates the usual metal reflector used with lights of this type, and it will be understood, of course, that this reflector may be of any desired contour. The light cluster, designated 2, has an upwardly extending threaded stem 3 passlng through the upper part of the reflector. A bail designated 4: and secured to a member 5 is held rigidly in place on the reflector by means of a nut 6 threaded on the stem 3, which nut also holds the light cluster in place on the reflector. The nut 6 is held in position by a lock nut 7. To place the light cluster and bail in position it is merely necessary to pass the stem 3 upwardly through the reflector, slip the bail-supporting member 5 over the topthereof and then screw on the nuts 6 and 7. It will be seen that both the light cluster and bail-supporting member will thus'be held firmly in position. The guard designated 8, which is of the usual construction, has, however, lateral extensions 9 and 10 passing through orifices 11 in the edge of the reflector, these orifices being slightly larger than the extensions 9 and 10 and permit of the guard 8 being swung-downwardly from the posi-.

tion shown in Fig. l, as on a hinge to permit of access to the light cluster 2, as shown in Figs. 6 and 7. In this position the guard is held in place by gravity and frictional action between the walls of the holes in the metal reflector and the'extensions 9 and 10.

It does not fall away from the reflector and consequently the workman when replacing the lamp need not concern. himself about the supporting of the guard any more than he would were there provided a conventional hinge, as, for example, the one shown in Patent No. 1,078,339. In order to remove the guard from the reflector, the workman merely grasps in his hand the guard and slightly raises it so as to remove its weight from the reflector. The guard then is readily detachable on account of the rela tive movement of the guard and reflector for this movement will disestablish the frictional contact between the parts. In placing the guard in position, it is merely necessary to insert the extensions 9 and 10 into the orifices 11 and swing the guard up- 'wardly until it'is in the position shown in,

Figs. Land 2, at which time a bolt 12 passing through a lip or extension 13 formed integral with the guard, if it is desired, is slipped into place, passing through the rim l l of the reflector. These lateral extensions 9 and 10 may take the form of lugs or projections suitably secured to the guard by welding or the like, or, if desired, may be formed integral with the guard. A nut 15 may then be screwed on the bolt 12 to hold the guard securely in adjusted position. At this time I wish to call attention to the fact that the extensions 9 and 10 cooperate with a flange 18 formed on the reflector so that as the guard is swung u into the position shown in Fig. 1, it wiil be placed under tension. This is of distinct advantage, in that, when the whole apparatus is in position, there will be no disagreeable rattling of the guard on the reflector as is oftentimes the case with apparatus of this kind now used in the art. In some cases it may be desired to have the guard 8 locked in position and for this purpose I have provided the device illustrated in Fig. 5, which comprises a U-bolt 16 passing through the lip 13 of the guard already referred to, this bolt passing upwardly through the rim 1 1 of the reflector when a pad lock 17 of any type may be locked thereto to prevent tampering with the guard, or with the light cluster.

It will be obvious from the foregoing description that so far as the cost of manufacture is concerned, as compared with the cost of manufacture of apparatus of this character now known in the art, it has been reduced appreciably. It has been customary to provide devices of some sort generally including a common hingeabout the edge of the reflector to hold the guard in position. These devices, as compared with merely forming extensions 9 and 10 on the guard and punching holes through the reflector, as in my apparatus, are expensive.

It has also been customary in this art to have the bail 4 secured to the reflector separately from the light cluster. This is more or less expensive, as compared with my method, and requires more time in assembling, thereby adding to the expense of the structure as a whole.

I do not desire to be limited to the precisedetails of construction and arrangement ofparts herein illustrated and described, as others skilled in this art might make various changes therein within the scope of the present invention. Therefore, what I claim as new and desire to secure by Letters Patent of the United States is 1- 1. In combination. with a reflector, a guard having an extension passing through the reflector to removably secure the guard to the same, the extension and reflector together forming a hinge to enable the guard,

to be swung into and out of guarding posi tion.

In combination with a reflector, a guard having an extension passing through the reflector to removably secure the guard to the same and cooperating therewith to enable the guard to be swung into and out of guarding position without entirely removing the guard from the reflector, the extension engaging the reflector before the guard is completely closed to cause the guard to be placed under tension when moved to closed or guarding position.

3. In combination with a reflector, a I

guard having a laterally extending portion passing through the reflector-and cooperating therewith to enable the guard to be swung into. and out of guarding position without entirely removing the guard from the reflector, the said extension engaging the reflector at a plurality of points as the guard is moved toward guarding position to retard further movement of the guard and cause it to be placed under tension as it is forced to full guarding position.

4. In combination with a. reflector, a guard having a laterally extending portion passing through the reflector for detachably securing the guard to the reflector, said portion cooperating with the reflector to form a hinge connection about which the guard may be swung into and out of guarding position, and a flange on the reflector engaged by the said laterally extending portion of the guard when the guard is moved to guarding position, the laterally extending portion of the guard at the same time engaging that portion of the reflector through which-it passes, the engagement of the said laterally extending portion of the guard and the flange on the reflector causing the guard to bind before it reaches full guarding position to put the guard under tension, as it is forced to closed position.

5. In a device'of the class described, in combination, a sheet metal reflector having an outer peripheral edge and provided w'th holes adjacent one another in the Wall the eof, adjacent said edge, and a guard having extensions corresponding in number to said holes,'said extensions and said holes cooperatin'g to provide a hingle-like joint.

6. In a device of the class described, in combination, a sheet metal reflector, a guard therefor, and interconnecting means therebetween for securely supporting the guard, when opened, by friction between the parts.

7 In a device of the class described, in combination, a sheet metal reflector, a guard therefor, and interconnecting means therebetween for securely supporting the guard, when opened, by friction between the parts, said guard becoming disconnectible by relative movement of the parts to establish the frictional contact between the parts.

8. In a device of the class described, in

combination, asheet metal reflector having holes adjacent one another and the edge of the reflector, a substantially rigid guard therefor, and means interconnecting them on one side to support the guard and to permit it to swing away from the reflector and be normally held in such position, said means comprising extensions adapted to be passed outwardly through said holes.

' 9, In a device of. the class described, in combination, a sheet metal reflector having holes adjacent one another and the edge of place.
