UNETED STATES SIMON W. FAB/BER, 0F BROOKLYN, YORK.

PORTABLE LAMP.

Application filed April 11, 1923. Serial No. 631,292.

To all whom it may concern:

Be it known that l, SIMON W. F ARBER, a citizen of the United States, residing at Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Portable Lamps, of which the following is a specification.

This invention relates to improvements in lamps of th type shown in my previous U. S. Patent N 0. 1,266,241.

My invention relates to a new and improved portable lamp.

One of the objects of my invention is to provide a portable lamp which can be placed upon or suitably clamped to any convenient support and which can be quickly and economically manufactured.

Another object of my invention is to provide a lamp of the above mentioned type comprising a plurality of movable parts which can be relatively adjusted so as to throw the light in a great number of directions.

Another object of my invention is to provide a lamp of the before mentioned type in which the parts will remain in any position to which they hav been adjusted.

Another object of my invention is to combine a friction device, embodying a spring, in a lamp structure of type so that said spring will serve as a friction device to hold the adjusted parts firmly, but movably, in position.

Other objects of my invention will be set forth in the following description and drawings which illustrate a preferred em-- bodiment thereof.

Fig. 1 is a side elevation.

Fig. 2 is a side elevation partially in section and showing the parts in a different relative position.

Fig. 3 is a rear View of Fig. 2.

Fig. 4 is a detail sectional view.

Fig. 5 is a top view of the base of the lamp, a portion thereof being broken away.

Fig. 6 shows my lamp applied to an automobile so as to serve as a trouble lamp, although my invention is not restricted to this purpose.

Th base portion of the lamp is comprised of an upper clamp 1 and a lower clamp member 2, the rear 3 of the lower clamp member 2 being substantially flat and the rear 4 of the up er clamp member 1 being preferably curved.

the above mentioned The upper clamp member 1 has two slots or openings 5 and 6 formed therein and the adjacent ends of thes slots are provided with two upwardly stamped flanges 7 and the other ends of the said slots, which may be. called the remote ends for convenience, are provided with two downwardly stamped flanges 8.

It can thus be seen that the top member 1 together with the flanges 7 and 8 thereof can be formed from a single piece of material and by the use of suitable dies so that the structure is very rigid and can be made very quickly and economically since the material for the flanges 7 and 8 is secured from that part of the upper member 1 which is stamped out of the slots 5 and 6.

The bottom member 2 is provided with two upwardly stamped flanges 9 which are adapted to be located closely adjacent the flanges 8 when the parts are assembled.

V The flanges 8 and 9 are suitably perforated so that a spindle 10 can be passed through them to connect the two clam members 1 and 2 so that they can be turne or partially revolved with respect to each other.

In order to keep the parts normally in the position shown in Fig. 1 for example, a coil spring S is provided upon the spindle 10 and this is provided with an upper portion 11 which normally bears against the upper member 1, and with two rearwardly inclined ends 12.

It is obvious that th base portion of the lamp constituted by the two clamping members can rest upon any suitable support, such as shown in Fig. 1, for example, or they can clamp around any suitable supporting member M shown in Fig. 2, such as for example, an automobile, as shown in Fig. 6. The standard 14 of the lamp 1s revolubly connected to the member 7 by means of a construction similar to that shown in Fig. 4 and which represents the manner in which the base of the lamp socket is connected to the standard 14: As clearly shown in Fig. 3, the standard'l l fits between the members 7 and is pierced at the bottom thereof so that it can be connected to the said member 7 by a threaded pin 15 having the head 16 and the nut 16.

The standard 14 fits. relatively loosely between the stilf upright members 7 and 1s adjustably held in position by means 'of a friction device similar to that illustrated in of said bore, which may be the right hand side thereof, has a diameter which is only slightly greater than the diameter of the pin 20 which corresponds to the pin 15 shown in Fi 3 and has a screw head 21.

he other side of the said bore, namely the left hand side, as illustrated in Fig. 4, has a bore large enough to permit the entrance of the friction spring 19. The pin or bolt 20 which may be suitably threaded for its entire length or only a small portion of its length has a nut 23 whereby the arm of the bracket 18 may be firmly secured in position, as shown in Fi 4.

The bracket 18, w ile it is made of stifl material is somewhat resilient so that the. arms thereof are bent inwardly to compel them to assume the position in Fig. 4 and the resilience of these arms tends to force them outwardly and against the screw head 21 and the nut 23. This frictional effect is further increased by the friction spring 22..

which, as shown in Fig. 4 tends to force the left arm of the bracket 18'against the nut 23. Hence there is a substantial frictional effect between the bracket 18 and the adjacent parts of the standard so that the parts remain in any relative position in which they are placed and it is further to be noted that this frictional device thus provided, is practically free from any wear and tear and subsequent loosening of the parts and loss of the frictional effect which is produced in other types of frictional devices by constant use.

The lampsocket 24 has the bayonet joint 25 and terminals 26 and in'itself may be of any old and well known construction, so that it is only diagrammatically illustrated in the drawings, as I do not wish my invention to be limited to any particular type of lamp socket.

The said socket 24 has the bottom thereof internally threaded and the bottom of the socket is adapted to rest upon the ring shaped bottom 27 of the bracket 28 which movably supports the reflector 29. A bolt or nut 30 having the shape shown in Fig. 24

is adapted to firmly hold the socket 24 in position. I

The reflector 29 which is made of any suitable material has an opening to admit the socket 24 and, as clearly shown in Figs. 1 and 4 it is provided with a bracket 28 secured thereto by rivets 30 or other suitable means. This bracket 28 and the shade 29 n freely revolve about the axis of the Socket 24, even though the socket 24 is firmly into position without exerting any frictional effect upon the ring shaped bottom 27 of the bracket 28.

In Fig. 6 this device is illustrated as being applied to an automobile to provide light for changing a tire orthe like and it is obvious that due to the adjustability of all the parts and the firm and reliable frictional devices provided that the light provided by the lamp can be projected in any direction.

The frictional joints provided at the bottom of the standard and at the top thereof afford a very wide range of adjustment in one plane and a revoluble mounting of the reflector provides a complete adjustment in a plane at right angles to the plane of movement of the said standard 14.

It will be noted that the spring 19 shown in Fig. 4 fits tightly within the bore of the standard 14 so that it exerts a frictional effect. Before the spring 19 is compressed into the position shown in Fig. 4 its outer diameter may be slightly less than that of the bore in the standard 14, but when the spring 19 is firmly compressed into position, so that the, adjacent turns thereof touch each other, the outer diameter of the said spring 19 becomes enlarged so as to secure the frictional effect before mentioned.

It is also preferable to have the pin 20 fit tightly within thespring 19.

A similar construction is found at I the lower part of the standard 14 in which a coil spring similar to friction spring 19 is located in a bore at the lower part of the standard 14. The members 7 serve to confine the said spring. A hole H can be provided in the lower member 2 so that the lamp can be hung on a nail or the like.
