SHADE HOLDER.

Application sied August 15,1922. serial No. sei-,m4,

To all 107mm t may concer/n Y Be it known that l, ALFRED J. MCMi-NN, a citizen or" the United States, residing at *the city and county of Denver and State ot llolorado, have invented certain new and useful improvements in Shade Holders; and lg do declare the following to be a full, clear, and exact description ot' the invention, such as will enable vothers skilled in thek art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to the characters ot reterence marked thereon, which form a part of this specification.

This invention relates to shade holders and has special reference to a holder of the type employed in connectionwith electric liXtures. j

lt is the object of this invention to produce Aa shade holder that is so constructed that the shade can be conveniently removed 4 therefrom and replacedtherein.

Vl Vaccomplish my object by means which l will describe in detail hereinafter and which consists Vbroadly in forming the ring,

which embraces the upper end oiE the shade, with a joint that can be quickly opened andV closed.

ln order to more clearly describe my inivention, I shall have reference to the accompanying drawing in which- F ig. 1 represents a side elevation or an electric lamp socket having a shade attached thereto by my improved holder, the upper part orD the'socket and the lower part of the shade being broken away.

Fig. 2 is a top plan view of my shade holder removed trom-the lamp;

Fig. 3 is a section taken on line 3 3, Fig. 2, and shows the means provided for engag` ing the bead on the shade;

Fig. 1 is a section taken on line 4 4, Fig. 2,v and shows the construction of the lock,` and The saine reference numbers will be'used to designate the same parts throughout the 5 is a section taken on line r5-5,

Numeral 1 represents Ya lamp socket of usual construction, having a bead 2 thereon, and 3 represents an ordinary incandescent lamp. ln order to hold the shade 1 in position about-the lamp, I provide avliolderV which consists of a central ring-like portion 5, which is open on one side and has its in Fig 3. y

rlhe inner ends of fingers 10 are pref r-' outwardly projecting ends 6 connectedby a screw 7 in vthe usual .manner pair of diametrically spaced arms S joins the ring 5 to a larger shade holding ring 9, which isl preferably of channel-like cross section andA is provided on its lower side with three or more inwardly projecting ngers 1G whose function it is to engage in the annular groove of the shade A1 in the manner shown ably upwardly and outwardly curved in the manner shown at 11 in Fig. 3, so as to conform more nearly to the curvature of the groove with which they cooperate. Ring 9 is cut and has its' ends 12'and 13 overlapped in -the manner shown in Fig. 2 and locked togetherl by means which l will now describe. rllhe endf12 is-inwardlyy oiliset the thickness of the material as indicated by numeral 14;'

(F ig. 2) `and is provided near its outer end with aV pin 15 which is adapted 'to enter and engage with the-'hole 16 in end 13 and thereby locking the two ends against longitudinal V imovement. A. slight inward pressure on end 12 at the point indicated by the arrows in Figs. 1 and 2 will remove the pin 15 from the hole 16 andpermit the en ds12A and 13 to spread apart. In order to guide the pin 15 .into the opening 16, I provide an outwardly pressed chanii'ed 17 within which Vthe point of the pin 15 slides when the ends are pressed together tor thev purpose or" locking them. The ring 9 ispreterably distorted slightly from the circular shape so that it will have a tendency tolopen, which tendency is resisted by the pin 15 engaging in the hole 16. l have shown only two arms 8, but Il may employ three if 1 so desire, although two'is considered to be sutlicient for ordinary purposes.

The operation of my holder Vis as follows :v

The holder is lirmly clamped in place on the socket by meansv oit the clamping ring 5 and the screw 7 in the manner shown 'in Fig. 1. rPhe lock that holds the ends 12 and 13 toOether is thenoaened and the u 3er e l Pl grooved end or" the shade 4C is inserted within the ring 9 in such a mannerthat the i'ingers 10 engage the groove in the manner shown in Fig. 3. The ends of the ringy are then squeeezed 'l together until Vthe vpin 15 engages the opening 16, when the shade will be securely held in place. Vhen it is desired to remove the shade end 12 is pressed inwardly until the pin 15 leaves the hole 16,

` g .I 1 i v Y 1,464,660

Vwhen the ends maybe lmoved .apart suiciently to permit the shade tofbe removed.

From the above it will be apparent that ll Ahave providedv ashade Vholder that is so constructed andv designed that the shade may be easily and vquickly attached thereto o r Vremovedtherefrom. Y y f Y'l desire toV call particular attention to K' the fact that my invention resides in the .construction and a snap loclr for securing combination ont a shade holder` of arspecial thel ends 'of the shade holdingiring. This typev of lool: is of 'great importance in a shade' helder having a separateY Shade clamp- Y ing ringf9. Ido not desire to claim broad: ly ashade holder having a snap lock for' holding1 the shade thereirnbut rather this in combinationiwith the other elernents shown. Having now described my invention, what 20 I clairn asnew- 1s;

shade holder consisting ofja clamping ring adapted to encircle a lamp socket, Y

and provided with a lock comprising'a pin onV one endV and an openingin thesother end,"

theV end Vhaving-.the hole being provided ith van outwardly pressed guideway for direoting'the pin into the hole, and inwardly projecting tiners'oarriedI bythe lower edge of the shade-holding ring `for engaging and .holding the shade.

In testimony whereof l Inysignature.
