ARTHHUR J'. TIZLEY, OF BROOKLYN, NEW YORK.

SHADE HOLDER.

Application filed July 22,

of Brooklyn, county ot Kings, and State of New York, have invented certain new and useful Improvements in Shade Holders,

oic which the following is a specification.

My invention relates to shade holders,

`10 and particularly to shade holders adapted to be applied to electric lamp sockets. rlhe object of my invention is to provide a shade holder having suitable means Jfor mounting the same upon the lamp socket together with means for engaging the trame oi' a shade of standard construction, the upper and lower portions oil the holder being preferably jointed to permit the shade to be tilted.

In the accompanying drawings- Figs. 1 and 2 are broken side elevations at right angles to each other, showing a shade holder in which my invention is embodied in one form, together with an associated lamp socket and shade engaged by the holder to which my invention relates;

In my prior Patent No. 1,246,497, dated November 13, 1917, l have shown a lamp shade having permanently associated .with its frame aA pair ot support-ing arms pivoted thereto, and carrying at their lower ends means for securing the shade lto a lamp socket, or thelike. This construction neces-V sitates a special frame and supporting arms permanently connected therewith and thus constitutes a combined shade and carrier.

The present invention provides a carrier 1921. Serial No. 486,722.

which is independent of the shade frame and is provided with means for detachably engagingashade' trame of standard construction. The particular means employed for this purpose maybe of any suitable sort, but is preferably of such character that it is adaptable to shade'trames of different size and construction, so that the carrier is in effect of practically universal utility.

As here shown, the carrier comprises a su) ort 15 adaated for mounting u aon a lamp socket 16, or other base member. This support may, for example, take the shape of a ring threaded to engage the usual threaded bead 17 (Fig. 4) adjacent the lamp-receiving end of the socket shell. tending trom opposite sides of the ring 15 are the rigid arms 18 and 19 of the supporting fork. Pivoted to the free ends of the latter are the arms 2O and 21 ot the shade-carrying yoke. The pivot joint may be of any suitable character, such for instance, as the friction pivot of my patent above mentioned. For simplicity of manufacture, however, these friction joints are shown as effected by rivets 22, the heads of the rivets being set down hard enough to cause sufficient friction at the joint to automatically hold the. yoke arms 2O and 21 in various positions of'angular adjustment ot the shade (see Fig. 2). A spring washer ot common type may beinserted between the arms to assist in this action, it desired.

In the construction illustrated, the head 23 ot the yoke is integral with the yoke arms 2O and 21, and bridges the latter. At its center, the bridge 23 is apertured to receive a screw bolt 24, and may be tapped to receive the latter, or `it may be a plain hole to permit the screw bolt to pass freely therethrough, as shown in Fig.- 5. An ornamental clamping nut 25 is threaded on the outer end of the bolt. In order to hold the bolt in iXed position during the screwing-up of the nut, some suitable means, such as a small holding nut ot common type engaging the thread of the bolt, m-ay be used where the hole in the yoke is plain. Or a drop of solder 26, as shown in Fig. 5, may be used Jfor this purpose.

The shade 27is ot standard construction and comprises a frame 28 with top spider arms 29 extending from a central pierced hub 30. To support a shade of this construction on the Vpresent carrier, it is only necessary to pass the stem of the bolt 24 through the hole in the hub 30 and clamp the latter against the yoke bridge 23 by screwing down the ornamental clamping nut 25 on the screw bolt 24. This may be accomplished either before or after the carrier is mounted on the lamp socket 16.

vSome shade frames, also of' standard construction, lack the hub 30 and their spider arms 29 are joined to a central strengthening ring 31. To adapt the present carrier for the'support of a shade of this construction, a pair of spring arms 32 and 33 are pinned to short offsets in the. yoke arms 20e-21 adjacent the bridge. At their ends, the spring' arms 32 and 33 are provided with fish-tail notches 311, which receive and support the ring 31. The spring action of the arms 32 and 33 presses the fish-tail ends against the ring, and thus maintain the joint.

modified form o-f device for this purpose is illustrated in Figs. 6 and 7, and comprises a star plate 35 of flexible material, centrallj7 pierced at 36 to pass over the screw bolt 2st. The arms of the star are of sufficient length to overlap the ring 31 of the shade frame, and may be bent around the latter to engage and support it. As a matter of convenience, the star arms may be corrugated, as at 37, at their outer ends, the better to grip the ring 31 when the ends are bent around the latter. It is obvious that by making the arms of sufficient length the star plate is adapted to engage rings 31 of different diameters for shades of different sizes just as the spring action of the arms 32 serves the same pur-pose. The star plate 35 may, however, be an independent element loosely mounted on the screw bolt 24.-, and may be discarded where the shade has a formof construction of the type shown in Figs. 1 and 2 and is provided with a hub 3f). Various other devices for accommodatingthe carrier to shade frames of different types will readily occur to those dealing with the problem.

l have illustrated in Figs. 8, 9 and 10 a simple and inexpensive base support for the shade carrier. In this modification the ring 38 is formed from sheet metal having threads rolled there-in to engage the threads 17 of the lamp socket. At the upper margin of the ring or lugs 39, which may be provided with marginal flanges 40 forming a channel to receive the lower ends of the fork arms 18 and 19, which may be joined thereto by rivets 41.

While I have shown the fork and yoke arms 18 to 21 formed from light strap metal, they may of course be made from wire or bars, if preferred. In any event, the carrier affords a simple and inexpensive fitting which may be applied to lamp sockets and shades of standard construction, detachably engaging each, so that both or either may be replaced if desired.y lts construction is such that shades of different sizes and didierenttypes of standard construction may be used therewith. ln all cases the carrier affords a substantial support from the socket and an angular-ly adjustable4 carriage for the shade to permit the latter to be tilted, if desired.

lt will be obvious that the attaching ring, or other attaching member, may be applied to any suitable lamp base other than a socket, such for instance as a candle tube, or the like, and in the following claims l use the expression lamp base in a sense broad enough to include such other structures. t is also obvious that if either pair of arms 18-20 or 19-21 be made strong enough, the other pair may be omitted, thus avoiding the shadow which the latter unavoidably causes. rthe star plate 35 may be made from wire, if prefererd, so that it creates less upward shadow-and increases the ventilation of the lamp, although sufficient ventilation is af forded by the construction shown.

Various modifications in detail of construction will readily occur to those dealing with the subject, which do not depart from what I claim as my invention.

I claim as my invention- 1. For use with a lamp shade having a skeleton frame element extending inwardly from the upper margin of the shade, a shade carrier comprising an attaching member for mounting the same upon a lamp base, supporting arm means rigid therewith, carrier arm means pivoted thereto a bridge extending between and integral with said carrier arm means, and means associated with the carrier arm means for detachably engaging said skeleton frame element of the lamp shade, said shade-frame engaging' means being engageable with frames of different sizes.

2. A shade carrier comprising an attaching member for mounting the same upon a lamp base, an upwardly extending supporting arm, a shade-carrying arm pivoted thereto, and shade-frame engaging means associated with the latter and comprising a substantially flat, detachable star member,- the free ends of the arms of which are deformable into supporting engagement with the frame of a lamp shade.

3. ln a shade casing, a shade-frame engaging substantially fiat star member, the ends of the arms of which are deformable into detachable supporting engagement with the surrounding ring of a lamp shade frame.

4. ln a shade carrier, a carrier arm having at its upper end a bolt and a clamping nut thereon, and an associated substantially flat, detachable shade-engaging star, the free ends of the arms of which are deformable into Supporting engagement with the frame of an associated shade.

5. In a shade carrier, an internally threaded sheet metal supporting ring adapted to engage a threaded portion of a lamp base, a

111g extending from the upper edge of said ring, and a supporting arm of heavier met-al riveted to said lug.

In testimony whereof I have signed my name to this specification.
