ELECTRIC-LIGHT SUPPORT.

Specification of Letters Patent.

Patented July 3, 1917.

Application filed May 23, 1916. Serial No. 99,408. I

To all whom it may concern Be it known that I, Giu'snern A. CnN'ro- LELLA, a citizen of the United States, residing at Clinton, in the county of Oneida and State of New York, have invented new and useful Improvements in Electric-Light Supports, of which the following is a specification.

This invention relates to an electric light support, primarily designed for holding and supporting an incandescent electric lamp with the component parts of the lamp fixture upon the arm of a sewing machine, in such manner as to adapt the light from the lamp to be directed upon the work to afford greater ease and convenience in sewin when the machine is used at night or in a ark place.

The object of thejnvention, is to provide a simple, convenient and inexpensive form ,of light fixture which maybe readily clamped to the arm of the machine and which permits adjustment of the lamp to different angles as required to direct the rays of light in the desired direction.

The invention consists of the features of construction, combination and arrangement of parts hereinafter fully described and claimed, reference beinghadto the accompanying drawing in which Figure 1 is a front elevation showing the application of the invention to the arm of a sewing machine, andshowing in full and dotted lines some positions to which the lamp may be adjusted.

Fig. 2 is a side elevation of the device. Fig. 3 is a top plan view of the same. Figs. 4, and 5 are longitudinal sections through portions of the lamp fixture. Fig. 6 1s a view showing a modification. In carrying my invention into practice,-I rovide a band or attaching member 1 which is adapted to embrace the arm of a sewing .machine and 15 provided with flanged ends 2 perforated for the passage of a bolt 3 provided with a securing nut 4, whereby the band when applied may be firmly fastened in, position on the machine arm. The band serves as the main support for the electric lamp 5 which may be of a type comprising a globe 6, socket 7 and shade 8 partially receiving and. inclosing one side of said globe,

and which may serve also as a reflector.

The socket 7 receives a threaded end 9 of a tubular connecting member 10, which is adapted to be securcdtherein against d1sat its opposite end with a pair placement by the usual set screw 11 upon the socket, the said connector 10 being provided apertured cars 12. a

The ears 12 of the connector 10 receive between them an car 13 formed upon a second tubular connector 14-: having at, its up posite end an apertured ear 15 arranged at right angles to the cars 12 and 13, which cars 12 and 13 are perforated for" the pas sage of a bolt 16 provided with a clamping nut 16, whereby the connecting members 10 and 14: are pivotally united and adapted for relative adjustment for articulating motion with greater or less freedom.

In practice, certain of the connecting of spaced members are preferably made of tubing having a greater or less degree of spring action or resiliency, so that the binding motion of the pivotally connected ears on each other may be varied and regulated by the connecting bolts, thus enabling the joined parts to be disposed at different relativeangles and held connected in a positive and certain manner without liability of relative dis-' placement. i

The second connecting member 14 has its car 15 arranged between the perforated cars 17 at one end of a tubular supporting arm 18, the said ears 15 and 17 being, disposed in a plane at right angles to the ears 12 andv 13 and being pivotally connected by a bolt 19- having'a securing and adjusting nut 20, whereby the second connecting member is adjustably pivoted to the free end of the arm 18.

The opposite end of the arm 18 is provided with perforated cars 21 disposed in a plane at right angles to the cars 15 and 17 and which engage flattened surfaces 22. at one end of a tubular connector 23, having a shank 23' which is perforated for the passage of a bolt 24 provided with a securing and adj u'stin g nut 24', whereby the members '18 and 23 are pivotally coupled forr'notion curing and clamping nut 28, whereby the" j be swiveled together, to permit rotative motion of the arm 18 through the connector 23, on the' band 1, as will be readily understood,

while permitting said'parts to be drawn to-.

gether and fixed in clamping engagement with each other against motion after adjustment, as will be readily understood.

In practice, the conducting cord or wire 31 leads through the arm 18 and connectors 14 and 10 to the socket 7 thus providing for the inclosure of the cord for supplying current to the lamp from a suitable source in such a manner as to prevent the cord from becoming kinked or tangled, while permitting it to bend or flex with the jointed elements of the supporting bracket or arm in disposing the lamp in difi'erent fworking positions. I v

It will be obvious from the foregoing de scription that when the band 1 is ap' lied to the arm ofa sewing machine, as in icated, the lamp 5 will be supported so that it may be bent upon the joints or pivots 16, 19, 24 and 29, so as to be disposed in different positions above, in advance or in rear 'of the machine arm and in difl'erent positions laterally and lon gitudinall of said arm, so as to throw light at di erent angles or from different positions toward-the work, while the eyes of the operator are protected by the shield 8, from the direct glare of the rays, thus enabling the workto be inspected at all times and clearl viewed, irres ctive of other natural lig t-conditions. he lamp may also be disposed in an out-of-the-way position when not in use, or so as not to interfere with the work at times when the use of an artificial light is not needed.

In Fig. 6 I have shown a modification in the construction ofthe swivel connection between the arm 18 and the connector 23. In

- this construction the split ring lis provided with a tubular portion 1" receiving a stem 22 which is fitted to turn or rotate therein.

-.against endwise movement while permitted to tu rn or rotate in said tube. -The stem is provided with an apertured ear 22 for connection with the cars 21 through the medium of the bolt 24.

If desired, instead of employing bolts with nuts .to pivotally connect the jointed sections, said sections may be unitedby headed pins or rivets arrangedto permit pivotal motion thereof, while maintaining the pivoted parts in frictional engagement to hold them in any position of adjustment.

I claim':

1. An electric light support comprising a lamp, a carrying member therefor, an attaching member, and a series of jointed arms connecting said carryin and attaching members, said arms inc uding a central tubular arm and intermediate arms, one of said intermediate arms being jointed in planes at right angles to each other to the 'lamp carrying arms and central tubular arm and the other of said intermediate arms being jointed to the opposite end of the central tubular arm to swing in a plane at right anglesto the pivotal connection of the firstnamed intermediate arm of the central tubular arm, said second-named intermediate arm being swiveled to the attaching member.

2. An electric light support for sewing machines comprising a lamp, a clamping member having a stationary I head thereon and jointed supporting arms- Iconnecting said lamp and clamping member, one of said supporting arms having a socket therein and a retaining flange partially closing the entranceto saidsocket, said supportingv arm and flange being split for the greater portionof the length on the socket forming gripping jaws for swiveling connection to said head on clamping member.

In testimony whereof I aflix my signature.
