SHADE-T'IOLDE-R- Specification of Letters Patent.

Patented J an. EA, 1913.

Application filed July 3, 1912. Serial No. 707,551.

T all whom it may concern:

Be it known that I, HARRY J. Monnr, a citizen of the United States, and resident of Syracuse, in.the county of Onondaga and State of New York, have invented certain new and useful Improvements in Shade- Holders, of which the following is a specification.

This invention relates to globe or shade holders and more particularly to a device for attaching the shade holder to an ordinary socket.

One of the objects of the invention is to provide a simple and inexpensive arrangement having few parts by means of which the shade holder shell may be attached to and ordinary lamp socket.

Other objects and the novel features of the invention will be apparent from the following description taken in connection with the accompanying drawings, in which:

Figure l is a side elevation of the shade holder attached to an ordinary lamp socket; Fig. 2 is an enlarged vertical sectional view of one-half of the shade holder shell showing the same attached to the socket shell, the section being taken along line 2-2 of Fig. 3; Fig. 3 is a horizontal cross-sectional view along the line 33 of Fig. 1; Fig. 4 is a perspective View of the upper part of the shade holder shell and the clamping ring, the parts being shown separated; and Fig. 5 is a plan view of the clamping collar and shade holder shell as assembled to be slipped into position over the bead on the socket shell.

Referring to the drawing, designates an ordinary lamp socket shell which has a circular outstanding bead or rib l1 adjacent its lower edge, as is usual.

12 designates a shade holder shell which may be of any ordinary or preferred construction and is shown as substantially frustoconical in form and stamped from a single sheet of brass or other suitable material. The shell 12 is provided at its lower end with any suitable arrangement for supporting a shade, such as a spring 13, which ar rangement is fully described in my co-pend ing application Serial No. 707,550, filed July 3, 1912, but constitutes no part of the present invention.

At its upper end the shell 12 has an in wardly projecting ledge or shoulder 1a, and at the inner edge of the ledge 14 there are upwardly extending resilient grasping or ribengaging members 15 and 16, formed by cutting the diametrically opposite notches 1'? and 18 into the edge of the usual neck portion and extending the notches to the shoulder lat. Near the upper edges of the members 15 and 16 beads form grooves 19 and 20 on the inner faces to cooperate with and spring over the rib 11 on the socket shell 10, which action is permitted by reason of the inherent resiliency of sections 15 and 16.

A loose clamping or looking ring or collar 20 is normally loosely supported on the inwardly projecting ledge 14: of the shell 12 and may be turned relatively to the same. When the upwardly projecting members 15 and 16 of the shell 12 are sprung over the rib 11, the ring 20 clamps the members 15 over the rib and prevents removal of the shell. The ring 20 has an outer knurled face and an inwardly projecting flange 22 at its upper edge. The inwardly projecting flange 22 has two cam lugs 23 and 24 on diametrically opposite sides thereof. The cam lugs 23 and 2% are of a longitudinal length slightly less than the width of the openings 17 and 18, and the ring is adapted to dropin place onto the shoulder on the shade holder shell, as shown in Fig. 5, by setting the inwardly projecting cam lugs 23 and 2st to register with the cutaway parts 17 and 18. The lugs 23 and.24t, when the collar is turned will engage the shade holder shell immediately below the rib thereon. The locking or clamping of the shell 12 into place is accomplished by rotating the collar or ring 20 in the direction of the narrow edge of the incline or cam edge which will afi'ord a binding or wedging action to force the members 15 and 16 inwardly. Knobs or beads 25 and 26 are punched outwardly from the interior of the shell 12 beneath the ribs on the neck in line to engage the forward or narrow ends of the cam edges 23 and 24: and limit the further movement of the collar 2O in that direction, thereby pre venting the same from being rotated into an unlocking position. Square or radially extending shoulders 27 and 28 are formed on the widest ends of the cam lugs 23 and 24 and engage opposite edges of the cutaway sections 17 and 18, and the collar 20 is limited thereby from being rotated in the wrong direction.

The neck portion which grasps the socket is of slightly greater diau'ieter than the socket shell and has resiliency so that the same may he slipped over the head on said socket and will be held in place to a 701- tain extent by the bead.

its the parts are assembled in the figures, the ring should be rotated counter clockwise to look, so that the narrow ends ol the cam lugs 23 and engage first and thus exert an increasing wedgin or binding action, and will be stopped i om rotating all the way around into unlocked position by engagement with the projections and 26. The shoulder 14 on which the lower edge of the collar travels and the ribs on the incmhers l5 and 16 against and beneath which the cam lugs and 24: on the u 'iper edge of the collar engage, constitute a guideway for said collar and positively hold the latter in position when the collar is turned.

it will be seen that l have provided a very simple two-piece shade holder for attachment to a socket and one which is cheaper to manufacture than most of such devices now on the market.

Having thus described the invention, what is claimed is:

1. A shade holder comprising a shell having an internal groove adjacent its upper edge adapted to receive a bead on a socket shell or other support, said shade holder shell also having a cut-away section extending into the shade holder shell from the upper edge across the groove, 21 ring hav ing an inwardly projecting lug provided with a cam edge fitting over the end of the shade holder shell adjacent the external rib corresponding to the internal groove therein and adapted when turned to exert a binding action on the upper end of the shade holder shell to clamp the same on the support, and means on said shade holder shell in the path of said cam edge to limit the movement of the ring.

in a device of the class described, the combination with a shade holder having an internal groove adjacent its upper end adapted to receive the rib on a socket shell, said shade holder also having a cut-a ray section extending inwardly across or transversely to the internal groove therein to permit the end of the shade holder to be sprung over the rib on a socket shell, and means for locking the shade holder against release from the socket shell coniiprising an annular member normally loosely mounted on the shade holder and having inwardly extending lugs at its upper edge provided. with cam edges adapted to engage beneath the rib on the shade holder corresponding to the internal groove therein, and exert a binding action to clamp the shade holder onto the socket shell.

8. The combination of a shade holder,

intense comprising a shell having an inwardly ere tending continuous shoulder at its upper end and an upstanding flange at the inner c ee of said shoulder, said flange having a t, tion thercol? cut-away and the remaining part being provided with an interior groove and an exterior rib corresponding to the :ove, said flange being adapted to be sprung over the rib on a socket shell so that said rib shall be received by the groove in the flange, and means for locking the shade holder shell to the socket shell, comprising an aunula r member normally loosely mounted on said shoulder and having an inwardly projecting flange at its upper edge prorided with an inwardly extending cam lug adapted to engage beneath the rib on the shade holder shell and exert a binding action thereagainst.
