Patented May 1, 1945 j a l. onTLET COLLAR FLANGE L Robert Haynes, San Francisco, Calif* [Application october 13,1943, serialNo. 506,117 4 3 Claims. y(o1. 22o-3.3)

' In many places vvhfere''electricall` outlet boxes areirequired, especiallyin connection with old work, there isnot suilcientworking room vfor a proper installation, such as could be 'cloneV on new work, and when the .ordinary boxand hang- 'er are employed, thefhanger bar rests on the upper surface o f the ceiling. `There is no way of fastening the hanger bar, unless the ceiling is cut away to give access to the,l hanger: but Aa cutting away of the ceiling is"undesira`ble, becauseit calls a plasterer on the job, to close the breachin the ceiling.

The present invention aims to provide such `astructure whereby `the difficulties above referred to may be remedied,` novel means being employed n kin "place and holding it securely anchored.`

It is within the `province Aof the disclosure to improve generally "andto enhance the utility of 'the invention resides in the combination and arrangement of parts and in the details of conf struction hereinafter described and claimed, it being understood that changes in the precise embodiment of theinvention herein disclosed, may be made within the scope of what is claimed,

Without departing from the spiritof the inven-l tion.

In the drawings:

Fig, 1 shows in transverse section, on the line I-I of Fig. 2, a. device constructed in accordance with the invention, most parts appearing in top plan;

Fig. 7 is a transverse sectional view showing another modified form of the invention;

`to which the present inven- Fig. 8 is an elevation showing a further modi- I cation of the invention; and

Fig. 9 is a vertical section of the structure disclosed in Fig. 8.

The device forming, the subject matter of this invention, may be made of metal throughout, although some other material may be employed electrical outlet structure, comprising an elongated clamp plate I `(Figs. 1 and 2), which is narrow enoughito be passed through a hole 2 in a barrierY 3, such as a ceiling. The clamp plate I engages one surface 4 of the barrier 3. The

A base plate. Sis provided, the base platehaving an opening 1 registering with theopening 5 of the clamp plate I.` The base `platei is of such size `as to engage Vthe opposite surface 9 of the barrier, and to overlapthe barrier, about the hole'2. f "Ti'ghtening devicesB, such asscrews,I kconnect the base plate 6 andtheclamp platelI-,to cause them to bind upon the barrier 3. "The tightening devices 8 are spaced apart at such distance that they` pass` through `the -hole 2` inthe barrier 3.

An inverted, cup-shaped box Illis supplied, and means is provided for connecting the box with the base plate, in communication with the opening 1 therein. I

The deviceformingfthe subject matter of this application includes modifications, and generic structure has been described, up to this point.

About its opening "I, the base plate 6 is provided with an upstandinglintegral collar I l (Figs. 1 and 2) which islpolygonal; and preferably octagonal ini cross secticn.I Nearits upper end,`the

collarII is slit asv shown at I2, to fashion-in-` posed, inwardly projecting ears I8, disposed directly above the ears I6 of the base plate 6. The box Il] is octagonal in cross section, and fits against rotation, within `the collar II, the box resting von the stop tongues I4.

Securing elements 20, such as screws, are engaged with the ears I6 and I8, to hold the box I0 in place. 'Ihe ears I5 may carry `screws Il, employed to hold a closure 2| (shown in dash line in Fig. 2) against the base plate 6, the closure extending across the opening 1 of the base plate or the screws I'I may be employed to hold in place, a hanger bar or other electrical fixture not shown.

the operator locates the box IU above the ceiling if there is a scarcity of`metal. It includes an 3, and attaches the flexible wiring conduits (not `one shown in Fig. 7.

shown). The collar H is slipped upwardly through the ceiling-hole 2 until the base plate or ange 6 is close to the ceiling 3, and the screws 8 are set up to clamping position. The operator reaches upwardly with one hand through the collar Il and pulls down the box Il) until it is within the collar and resting on the stop ears I4. By means of the other hand, draw screws 20 are mounted in the ears I6 and I8, and are tightened, and the partsappear as in Fig, 2,

The construction is such that the box 1D Vis spaced from the base plate 6 `by 'a greater distance than ordinary, to provide a structure of greater height than the one shown in Fig. 7, which is to be described hereinafter.

In Figs. 1 and 2 of the drawings, the collar Il is integral with the base plate 6. This detail is not necessary, as Figs. 3, 4, ands show. In the figures last mentioned, parts hereinbefore described have been designated by numerals already used, with the suflixa Thecollar .l ia is provided at its lower end with dependingflngers 22, adaptedvto be inserted through openings .23 in the'base plate 6a. When the ngers 22 are bent upwardly, :they distort or hump upwardly small reception ofthe bent portions of the ngers 22.

The construction is such that a smooth surface is provided, to receive the blanking disc or closure .21 of Fig. 2.

. AIn Fig. 7 the collar H of Fig. 2, or thecollar VvHa. of 4Figli, has been omitted, parts hereinbefore describedhaving been designated by num-erals already used, with the suiiix b. The ears I8b of the box Ib rest immediately upon the ears .Ibrof the `base plate 5b, and the screws 29h connect the parts specified.

l)En Figs. 8 and 9 there is shown a form of the invention which is adapted to .be used to house a switch structure, parts hereinbefore described having been designated by numerals already used, with the suiiix e.

This .form of the invention .is much .like the The ears 15e ofthe base plate .6e lare provided with openings 24, for the reception of the binding screws 20c, and on opposite sides of each opening 24 there are other openings 25 which facilitate the mounting of the switch in place.

Having thus described the invention, what is claimed is:

l. An electrical housing structure comprising a clamp plate having an opening, a base plate spaced from the clamp plate and having an opening .registering with the .opening of the clamp plate, a collar carried .by the base plate-and distures, an adjustable tightening device connecting the inwardly projecting structures of the box and ci' the base plate, to hold the box seated lon the stop (means, and an adjustable tightening device connecting the base plate with the clamp plate .andlocated outwardly -of the collar.

2, An electrical housing structure constructed as set Iorthin claim l, and wherein the collar and the base plate are integral.

.3. An electrical housing structure comprising a .clamp plate having an opening,'a base plate spaced fromthe clamp plate and having an opening registering with the opening of the clamp plate, a collar carried by the base plate and disposed about the opening of the base plate, the collar extending through the opening oi the clamp plate and Ihaving inwardly projecting stop means, an inverted box extended within the A.collar and seated on the stop means, the box and the base plate having inwardly projecting structures. an adjustable tightening device connecting the inwardly projecting structures of the box and of .the base plate, to hold the box seated on the stop means, an adjustable tightening device connecting the base plate with the clamp plate and .located outwardly of the collar, the base plate being provided with inwardly projecting ears, and adjustable tightening devices mounted
