To all whom it may concern."

Be it known that I, J AMES L. Roms, a citizen of theUnited States, residing at Amistad, in the county of Union and State of New Mexico, have invented new and useful Improvements in Gas and ElectricFixture Attachments, of. which the following is a specification.

This invention relates to electric, combi ing a means for leading the Wires out formakin connections, thereby dispensing with outlet oxes and accessories; or a means for connecting combination gas and electric, or

gas fixtures to gas or other rigid pipe, all of which have the adjustable feature set forth heretofore.

A further object of this invention is to provide a simple, strong, durable, safe and inexpensive means for conducting wires out from concealed places, in such as knob, cleat, flexible loom, or other style of concealed work, or from open work, molding, or other accessible methods of wiring; the same being applicable to all styles of old work as Well as being adaptable to new work, in that it can be installed to advantage while the structure is in process of construction, and be ready for the fixture as soon as the conditions will permit the use of the same.

A still further object of the invention is to provide a means for applying this adjustment movement, commonly known as a ball and socket joint, by the modifications set forth hereinafter to the various methods of wiring and piping for fixtures, and to be applicable to the various shapes and styles of supports used for the receiving of fixture stems and the support of fixtures.

The invention consists in the novel construction and combination of the several parts as hereinafter set forth and described in connection with the accompanyin drawings, which form a part of thls 'speci cation,

while its novel features will be particularly pointed out in the appended claims.

- Further objects of the invention will appear as the following specific description is read in connection with the accompanying A drawings, Which form part of this application, and in which Figure 1 is a section showing parts in elevation of one form of the fixture. F 2 is a detail sectional view of the separate parts I usedin Fig. 1. Fig. 3 is a sectional view showing the structure in Fig. 1 installed under extreme conditions. Fig. 4 is a'detail sectional view of a modified form- Fig. 5 is a top plan view of the structure shown in Fig. 4:. Figs. 6 and 7 show similar views in different positions. Fig. 8 shows a sectional view of a further modified form of fixtures Fig. 9 shows the application of a hickey to an outlet box. Flg. 10 is a similar view showing the hickey connected to the ordinary crowfoot. Fig. 11 is a sectional view of the ball socket.

Referring more particularly to the draw-' ings, 1 represents a crowfooL of special design having a bowl 2 in which is seated a semi-spherical ballv 3 having a centrally threaded aperture 4. The bowl 2 is spherical, or substantially so, upon itsexternal and internal'surfaces and the radius of the convex surface of the ball 3 is slightly greater than the radius of the concave surface of the bowl 2. Threaded in the ball is a-two-part conduit pipe 5 whose sections meet approximately in the vertical center of the ball and with the upper section extendingabove the crowfoot and the lower section extending through an aperture 6 in the bottom of the bowl and having its lower end threaded, as

at 7, to receivethe sleeve adjusting nut 8. A sleeve 9 surrounds the lower end of the conduit tube or pipe 5 and has its lower end resting upon a washer 1'0 surrounding the tube and supported by the nut, and its upper end in engagement with the under side of the socketll whose concave surface has a radius slightly less than the convex surface of the bowl 2. By adjusting the the socket 11 is forced into engagement with the bowl 2 and the ball is pulled vdoWn'into engagement with the bowl, so that the bowl of the crowfoot is gripped upon its internal nut 8 upon the end of the conduit tube 5 and external surfaces, the relative relations of the radii of these respective parts being 'such that when the ball and socket arev drawn together they will bind effectively upon the bowl to hold the tube at any angle to the "crowfoot which can be obtained, the,

tach the same to a lath and plaster support.

Surrounding the tube '5 and having its upper end abutting against the socket 11, is a shell 14 in the form of a frustum of a cone which is held in place by a washer 15 upon which the shell rests and which is held in position by the nut 8. This shell is used to serve as a form for the outlet through ahole in the ceiling. WVhen this form of fixture is used with new work the shell is placed in position before the lath or plaster or other finish is applied and may be left in such posit-ion, or used again. The washer 10 is removed before attaching the fixture.

In Fig. 3, the device is shown applied in an extreme condition where a ceiling support 16 is shown carelessly installed be tween the floor joists 17, the upper end of the conductor tube 5 extending through an aperture 18 therein and the crowfoot secured directly with its bowl in registry with the aperture. The adjustment of the device will be seen to readily permit the conductor tube to pass vertically through the ceiling 19. The lower end of the tube left exposed beyond the nut 8 has threaded thereto an ordinarycommercial hickey 20 having side apertures 21 for the passage of the electric wires, so that a joint can-be conveniently made between the fixture wires and the leading-in or

feeder wires

22 and 23 respectively. The lower end of the hickey is threaded and secured therein is a fixture stem 24 to which is secured the fixture casing 25 surrounding the same and carrying an adjustable collar 26 upon which a fixture canopy 27 is supported to cover the hickey and aperture in the ceiling formed by the shell 14.

In Figs. 4, 5, 6 and 7, the device is shown applied to an ordinary commercial crowfoot 28 having a threaded aperture 29 in its base and a substantially spherical outer surface. Seated in the crowfoot is a substantially semi-spherical member or ball 30 having relatively large through aperture 31 adapted to receive the adjusting screw 32 which passes through the apertures 31 and 29 in the member 30 and crowfoot 28 and engages the threaded aperture 33 formed at the base of the socket 34 which is formed upon the upper end of the hickey 35. The upper end of the screw is provided with a head 36 having a plurality of apertures 37 therein adapted to receive an adjusting tool which may be in the form of a spike 38, as shown in 5. By turning up the screw 32 the socket portion of the hickey is drawn into engagement with the outer spherical surface of the crowfoot bowl, and the hickey is held in adjusted position with relation to the crowfoot. The large aperture 29 in the crowfoot permits a relatively wide adjustment of the screw 32 and the hickey connected thereto and the aperture 31 in the ball 30 is made considerably larger than the screw, so as to allow the head thereof to retain its fixed relation to the socket and to allow the ball to adjust itself to the crowfoot. The lower end of the hickey 35 is internally threaded and mounted therein is a fixture tube 39 throughwhich the conductor wires 40 pass.

Tn Fig. 8, an ordinary metal conduit 41 is shown as projected through the ceiling 42 and provided with a threaded lower end upon which is mounted a hickey 43 having a spherical lower end 44 and a central aperture 45 which communicates with side apertures 46 through which the fixture and'leading-in wires 47 and 48 respectively may be connected. Surrounding the spherical ball 44 of the hickey is'a split socket 49 having the internally threaded lower end adapted to receive the fixture tube 50. This tube has its upper end threaded for a considerable distance and, mounted upon the threaded portion, is a nut and washer 51 to bear against the lower end of an inverted cone frustuin 52 which has its upper internal portion recessed, as at 53, to receive the fingers of the split socket 49. The fingers of the split socket 49 are sufliciently resilient to snap over the ball or sphere 44 and the frustum or shell 52, when operated upon by the nut, holds the fingers together in engagement with the ball so that the fixture tube 50 may be held in adjusted position.

In Fig. 9, the type of hickey shown at 43 is illustrated connected to an ordinary outlet box 53 by means of a threaded supporting stud 54.

In Fig. 10, a commercial form of crowfoot is shown at 55 having a threaded nipple 56 secured in its lower end and adapted to receive the hickey. Tn this type of hickey the side apertures 46 are omitted and only the straight central aperture is provided, the wires coming" in between the legs of the crowfoot and extending down through the nipple and hickey which may have the fixture connected thereto, as shown in Fig. 8. In place of the washer shown above the nut 51 the canopy shown at 27, in Fig. 3, ma be secured so as to cover the jointat the cei ing or side wall.

Having thus described the invention, what I claim as new is 1. In combination, a fixture tube, a support, a universal connection between the tube and the support for adjusting the tube relatively to said support, fixture wires in the tube, incoming wires, and a hickey connected to the tube and having side apertures to permit the connection of the incoming ancl crowfoot having a bowl, a ball seated in'the bowl, a concluctor tube passing through the ball, a socket member engaging the bowl, a sleeve surrounding the tube, and means for forcing the sleeve against the socket member, whereby the latter will be held in engagement with the bowl.

3, In a device of the class iescribecl, a crowioot having a bowl, a ball seatecl in the bowl, a conductor tube passing through the ball and connected thereto, a socketmember surrounding the tube and adaptexl to engage the bowl, a sleeve surrounding the tube, anti a nut on the tube adapted to force the sleeve into engagement with the sachet member hold the latter in engagement with the exterior of the bowl the ball in engagev rnent with the interior of the bowl,

4., In a olevice of the class describecl, a crowfoot havi a bowl, a ball seated in bowl, a conductor cube passing through the ball and connected thereto, a socket member surrounding the tube and. adapted to engage the bowl, a sleeve surrounding the tube, a nut on the tube adapted to force the sleeve into engagement with the socket member and hold the latter in engagement with the exterior of the bowl and the ball in engagement with the interior of the bowl, a fixture tube, and a connecting device for joining the fixture tube with the conductor tube and having apertures to permit the joining of inlet and fixture wires.

5. in combination, a sectional conductor tube, means for connecting the sections, a

socket member surrounding said means, ancl means adjustably secured on one section of the tube for holding the socket member acijustably clamped on the connecting means,
