ROBERT M. DIXON, OF EAST ORANGE, NEW JERSEY, ASSIGNOR TO SAFETY CAR HEATING 85 LIGHTING COMPANY,

A CORPORATION OF NEW JERSEY,

FASTENING MEANS.

Patented Aug. 2, 1910.

Application filed August 29, 1907. Serial No. 390,607.

To all whom it mag concern: I

Be it known that I, ROBERT M. DIXON, residing at East Orange, in the county of Essex and State of New Jersey, have invented This invention relates to certain improve I ments in fastening devices, but inasmuch as many of its characteristic advantages prominently appear in its embodiment as a shade holder for illuminating devices, it will be conducive to clearness to disclose this invention in such relation. 1 V

This invention has in viewamong other objects the provision of a shade holder which, structurally considered, will be of the greatest possible simplicity and compactness and be composed of but few parts all of which may be manufactured at a minimum of cost. I

This invention also contemplates a shade holder which will in practical usa e possess great durability and positiveness of action and which may be operated with the greatest ease for the purpose of renewing shades.

A further object of this invention is to devise a shade holder which will be sightly in appearance, bein free from undesirable projecting parts suc as screws or the like, and which will rigidly and firmly retain the shade, in place without being loosened by vibrations such as those common to railroad cars when traveling.

Other objects and advantages will be in part obvious from the annexed drawings, and in part pointed out in the following description.

This invention accordingly consists in the features of construction, combinations ofelements and arrangements of parts which will be exemplified in the construction hereinafter set forth and the scope of the application of ,which will be indicated in the following claims.

In order that this invention may be the more fully understood and made compreherrsible to others skilled in its relating arts, drawings illustrating one of the several possible utilizations of the same are appended as a part of this disclosure and, Whilo'the characteristic featuresand principles of this I invention may be otherwise applied by modification falling within the intendedsco e of the claims, the herein disclosed embodiment may be advantageouslyresorted to in practice .andis regarded as representing substantial improvements over many of the seeming equivalents of this invention. In the accompanying drawings, corresponding parts are similarlyireferred to by the figures of which;

latter to be removed.

Continuing now with a more detailed deof this invention, with such-occasional reference to the appended drawings as may afford a clear comprehension of the same, 1 denotes the body portion of a bracket adapted for use in connection with electric lamps. This bracket may comprise a wall portion which may be mounted the lamp socket 4 will ordinarily provide a channel such as that denoted by 6 for enabling the electric socketin the usual'manner.

The shade supporting member or portion 8 may, of course, constitute an integral part may dictate. This supporting member-8 is the open coil securing ring-9 to'be coiled into like'characters of reference throughout all script-ion ofthe herein disclosed embodiment 2 whereby it may be secured to a wall anda lamp socket receiving portion. 3; within-- feed wires to be led to the terminals 7 of the so devised as to properly engage with a securing ring 9 which is here 'shownto be in the form of an open coil, having" a "single convolution. To this" end the supporting member 8 may be provided with an inner. groove 10'andan'opening 11 so .as-to'enable Figure 1 is a vertical section partly in eleof engagement with the shade to enable the adapted to receive the bulb 5. Such bracket of the bracket or it may be detachably carried by the bracket or otherwise as occasion ee P t 9? h ew Qfz 'r e s the:

same through approximately 360 in the directions indicated by the arrows shown on Figs. 3 and 2 respectively. Preferably the inner end of the coiled ring is beveled and provided with a grooved seat 12 and the complementary edge of the opening in the supporting member may be provided with an inclined face 13 so as to promote the ready entrance of the inner end of the coiled ring into the groove 10. The supporting member may also be exterior-1y provided with a groove 14 adapted to retain the ring 9 on the supporting member when such ring has been withdrawn from the inner groove and also serving to retain such ring inproper alinement with'the inner groove so that it will always be in proper relation therewith to enable it to be immediately forced into theinner groove without involving anyv adjustmentor other undesirable.

manipulation.

The shade 15 is provided Witha groove 16 around its attaching end which is complementary to the groove lOof the supporting member so that when the ring 9 is in the position indicated by Fig. 2 it will engage and lock together both the shade and the supporting member.

It will thus be perceived that I have succecded in devising a means admirably adapted to achieve the several objects and ends of this invent-ion. To secure the shade to the bracket, the parts will first be brought into the relation shown by Fig. 3 whereupon a single revolution of the ring 9 the direction indicated by the arrow will cause such ring to coil into the inner groove of the supporting member 8; and also engage with the complementary groove of the shade as indicated by Fig. 2. Inasmuch as the ring 9 will possess acertaindegree of resiliency the finger grip end 17 will be sprung into contact with the inner end of such ring bringing the parts into the closely interfitting and coin pact relation shown by Fig. 2. Vith the parts so positioned, it will be found that they will not be shaken loose even under excessive vibrations, but on theother hand the shade may be removed With the greatest of facility by'merely rotating the ring in the direction of the arrow shown on Fig. 2 thereby causing the end 17 to ride up the beveled ed e 18 and into the exterior groove 14, thus withdrawing the ring from its ins tel-locking relation.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departin from the scope thereof, it is intended that a l mat-- ter contained inithe above description or shown in the accompanying drawings shall be interpreted as illustrative and not in. a limiting sense. i I Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A device of the nature disclosed comprising, in combination, a supporting memher having a. ring retaining seat and having an opening in communication therewith, a shade having a conmlementary seat, and a ring having the form of an open coil adapted to be passed endwise through said opening into engagement withsaid seats to secure said shade to said supporting member.
