FIXTURE SUPPORT.

Application filed February 17, 1928. Serial no. 619,549.

My invention relates to a support for fixtures and the like and is particularly adapted to securing to a wall or ceiling articles such as bath room accessories, electric light fixtures, and other devices in which it is desirable to so secure the device to the wall that the securing and supporting means shall be concealed from View.

A considerable difficulty has been experienced in securing fixtures of this class to a wall or ceiling in a substantial manner, since, heretofore the usual practice has been to secure such fixtures by means of screws passing therethrough into plugs, expansion olts, or the like, fastened in the wall. This has involved accurate drilling of relativelv small holes which frequently resulted in the cracking or other mutilation of the wall and produced an attachment which lacked strength and was frequently unsightly.

According to my invention I am enabled to firmly attach fixtures to a wall of cement, plaster or similar material, and my improved device is arranged so that the upported fixture is, through the attaching means, drawn into close contact with the wall. When attached no screws or other attachin means are visible.

In t e drawings accompanying this specification I have shown In Figure 1, a cross sectional view of one form of my invention,

In Figure 2, a plan view thereof,

In Figure 3, a cross sectional view of a modified form of my invention, and

In Fi ures 4 and 5, vertical and cross sectional views of another modification thereof.

Referring to the drawings, it will be seen that my device comprises a supporting member 1 and a supported member 2, the supporting member being embedded in the wall :3. The wall may be faced with tile 4, or other similar material and the supporting member is inserted in the wall by drilling r a relatively large recess 5, which need not be of any exact dimensions, filling said recess with plaster of Paris or other suitable material and inserting the supporting memher 1 therein. i

The supporting member 1 is provided with lateral extensions 6,of the sha e shown, and to permit easy entrance oftne lateral extensions through the plaster of Pariswhile the same is still in a plastic condition.-

but to prevent the supporting member from Paris t e plaster of Paris maybe easily displaced but that when it is attempted to withdraw it it is wedged between the wings 7 and the other portions of the supporting member toform a substantial anchor.

Mounted upon and fixed to the shaft of member 1 is a disk 8 which vacts to prevent the material 5 from being forced out of the recess when the end of member 1 is inserted withm said recess. The disk 8 also serves to limit the positionin of the entire member 1, which, as has iiefore been stated is the supporting member. As shown in Fig. 2, the dlslr 8, may, and preferably does have a lug or 11p formed on the edge thereof. The lug or 11p 9, it will be obvious, serves to position the supported member 2 and to prevent rotation of the latter, by being fitted within a recess 9' formed in member 2, as clearly shown in Fig. 2. It will also be obvious that if the member 1 is embedded in the wall with regard to the position of this lip 9, the member 2 will have a correspondingly correct position when attached to the member 1. The supported member2is adaptedto cover the exposed portion of the supportmg'member as shown inthe drawmgs, and is provided with suitable means, such as set screw 11, for engaging the supporting member. The latter ad acent its exposed end is formed with a taper which may take the form of an annular groove 13 as shown in Fig. 1. The arrangement is such that the tightening set screw in engagement with the taper will force the supported member in the direction of the wall and thus insure a tight fit between the supported member and the wall. It will also be noted that all of the fastening means are covered by the flange on the supported member, and that the only fastening member exposed is the head of the set screw 11, which may' be put in an inconspicuous position. When desired, a portion of the same fastening means may be used, as shown in Fig. 3, in which modification the disk or plate 8 is'attached to thewall by means of screws 12, and the anchor portion of the supporting member omitted.

The modification in Fig. 3 is adapted for use on wood or metal, or other substances in which screws can obtain a firm hold and which it is inconvenient to drill and fill with plaster as described above in connection with the modification of Fig. 1.

If desired, the lip 9 may be omitted and the set screw or other means may be used to perform the functions of the lip as well as the other functions performed by it. Such an arrangement is illustrated in Figs. 4 and 5 in which modifications a tapering slot 13 is cut in the supporting member, with which slot the set screw or other means carried by the supported member cooperates. It will be understood that this modification is applicable equally to the device shown in Figs. 1 and 3 and that, if additional precautions against rotation are desired to be taken, the lip may be used as well. If the modification of Figs. 4 and 5 is used, the disk 8 may be entirely omitted or a laterally extending pin 14 or other similar device for positioning the supporting member may be used, although I find the disk 8 useful because it positions the supporting member normal to the line of the wall without the exercise of any great care on the part of the user.

While I have only described the forms of my invention which I refer and have found use for in practice, I 0 not wish to confine myself thereto as it will be evident to those skilled in the art that many modifications may be made without departing from the spirit of my invention.

It will be noticed that by a very simple structure I attain important results, that is, I get an easy, rigid and permanent assembly. In fixture supports, generally, the supported member'has been inclined to wabble more or lessv in some cases to a considerable extent and in some cases only sli htly on its supporting member. This web lin ultimately results in the supported mem er becoming loose, either by disturbing the support or by loosening the fastening screw and the fixture ultimately falls apart, or becomes shaky or ugly in appearance. Where the two parts are fastened together by a set screw going through a part of the supported member and into the supporting member,'as, for example, in the structure shown in the patent. to Wells No. 1,27 6,463 of August 20, 1918, it is diflicult to have the fastening or binding screw register accurately with the hole in the stem, which it is supposed to enter and therefore it is difficult to assemble the structure, Moreover, in a structure of this kind there is likely to be more or less play at the base of the supported structure and between it and the wall with which it abuts, so that this will cause vibration and wabbling. In other structures the stem of the supporting member has been made in two pieces to provide for expanding the stem, and, to a slight extent, for adjustment of the supported member, but structures of this kind are undesirable because of the fact that the stem does not transversely fill the socket of the supported member as it should and reliance has to be had on the fastening screw, and wabbling and vibration result.

Furthermore, the multiple part structure is objectionable because of the expense and the fact that the parts are likely to be im-' properly fitted or become dis laced or lost in shipment. All these difficulties are overcome bymy improved structure.

It will be noticed that the stem 1 is of the same cross-sectional shape and transversely fills the socket of the member 2 and that the inclined surface of the stem, when engaged by the screw 11, causes the base of the part 2 to be brought into firm contact with the adjacent wall so that the parts are held against possible loosening. This, rigidity of structure is further enhanced by'the fact that the lip 9 on the edge of the member 8 engages a complementary part 9 in the member 2, so that when the latter is positioned it cannot turn and it cannot move lengthwise. To get at this result it has sometimes been the practice to have a lug on the face of the part marked 8, correspond-v ing with a complementary socket in the wall of the member 2, but this structure is objectionable for the reason that it is difiicult in (practice to have the partsalw'ays register an to brin them into proper connection. By having t is lip on the edge of the member 8, however, it is a simple matter to turn the member 2 so that the recess 9 will register with the'part 9, and thus when the structure is erected there is no possibility of the fixture turning or movin axially and, consequently, the erection o the parts is easy and permanent.

What I claim is:

1. A fixture support comprising a supporting member having a rigid one-piece stem. with a recessed part, the outer wall of which is inclined towards the base of the stem, means for attaching thestem to a support, a supported member having a socket which fits over the stem of the su porting member so that the stem substantial 1y fills the socket transversely, and, a fastening member carried by and adjustable in the supported member intersecting the socket and impinging on the outer inclined wall only ofi the recess of the stem thereby moving the supported member endwise towards its base.

2. A fixture support comprising a supporting member having a' rigid one-piece stem with a circumferential recess therein, the outer wall of the recess being inclined toward the base of the stem, means for atlull taching the stem to a sup member having a socket w ich fits over the stem of the sup orting member so that the stem substantiai y fills the socket transversely, and a set screw carried by and "adjustable in the supported member intersecting the socket and impinging on the enter inplort, a supported clined wall only of'the recess of the stem thereby moving the supported member endwise towards its base. 4

In testimony whereof, I have signed my name to this specification this 5th day of February, 1923. a
