DANIEL LUGKWALIDT, SAMUEL L. KATZ, AND FRANK GROSSMANN, OF CHICAGO, ILLI- NOIS, ASSIGNORS, BY MESNE ASSIGNMENTS, TO CHARLES WEICENSANG.

OUTLET-BOX SUPPORT.

Application filed June 21, 1922.

To aZZ whom it may concern-.-

Be it known that we, DANIEL LUCKWALDT, SAMUEL L. Kyrz, and FRANK GRossMANN, all citizens of the United States, and residents of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Outlet-Box Supports, of which the following is a full, clear, and exact description.

The invention relates to outlet box supports and its object is to provide an improved support in which the supporting bar and adjustable supporting head thereon are retained in connected relation before the bar is installed and another object is to provide an improved support of this character which is simple in construction and can be produced at a low cost.

The invention consists in the several novel 20 features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Fig. 1 is a perspective of a support embodying the invention. Fig. 2 is a side elevation, an outlet box and the nut on the supporting head being shown in section. Fig. 3 is a section on line 33 of Fig. 2. Fig. 4 is a vertical section.

Theinvention is exemplified in a support l comprising a bar 5 usually formed of flat stock of sufiicient length to extend between the joists of a building. The ends of said bar are provided with holes 6 for screws or other devices for attaching the bar to the joists. In practice, the perforated ends are usually bent at right angles to fit against the adjacent faces of the joists, as well understood in the art. This bending is usually done at the place of installation so that the bar will fit properly between joists which are differently spaced. A longitudinal slot 7 is out in the bar 5 so that the bar will comprise side members 8. This slot is of suflicient length to permit the members to be flexed relatively to one another to permit the insertion of a carrier head and so that it will be locked against separation from the bar while permitting longitudinal adjustment thereof to position it at the desired point a between the joists. The carrier head 9 is provided with notches 10 in its sides to receive the side members 8 of the bar 5. By using a screw-driver, members 8 may be pressed apart suiiiciently, as indicated by dotted lines i'n'Fig. 4, to permit the upper the desired position.

portion of the head to be inserted between said members and when the latter are released, they will spring into normal position shown in full lines in said figure and, thereupon, the headwill be held in connected relation to the bar, but adjustable longitudinally of the bar. A depending screw 11 is integrally formed with the head 9. A nut 12, fitted to said screw, is adapted to engage the underside of an outlet box 13, so that the box .will force the bar upwardly against the upper faces of notches 10 and cause the bar and outlet box to be clamped between the nut and the head. By tightening the nut 12, the outlet box and carrier will be conjointly secured against movement relatively to the bar. hen the nut is loose, the outlet box and carrier head may be adjusted longitudinally of the bar to bring the outletbox into The invention exemplifies an outlet box support comprising a bar and head which are adapted to be connected against separation by flexing members of the bar and in which the head is provided with notches in its sides to receive the members of the bar. The construction is advantageous in that it makes it possible to assemble the head and bar at the factory and can be produced at a low cost.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.

Having thus described the invention what we claim as new and desire to secure by Letters Patent, is: l

1. In an outlet box support, the combination of a sup-porting bar comprising a pair of longitudinally extending side members with a space therebetween, a head extending through the s ace and having notches in its sides to receive the members of the bar respectively and sildably connect the head, 190 and bar, the head being secured against separation from the bar while said members are in said notches, the head being of greater width than said space and insertable into said space, and means on the lower end of ghe head for securing an outlet box to the 2. In an outlet box support, the combination of a supporting bar comprising a pair of longitudinally extending side members with a space therebetween, a head extending through the space and having notches in its sides to receive the members of the bar respectively and slidably connect the head and bar, the head being secured against separation from the bar while said members are in said notches, the head being of greater width than said space and insertable into said space, an integral screw on the lower end of saidhead and of greater diameter than the width of said space, and a nut on the screw to secure an outlet box to the bar.

3. In an outlet box support, the combination of a supporting bar comprising a pair of longitudinally extending side members with a space between and relatively flexible to permit them to be spread, a head of greater width than the space and insertable into said space by the spreading of the members and provided with means to hold it in connected relation to the bar when the side members are-in normal position, and means on the head to support an outlet box.

4. In an outlet box support, the combination of a supporting bar, comprising a pair of longitudinally extending side members with a space between and relatively flexible to permit them to be. spread, a head of greater width than said space and insertable into said space by the spreading of the members and provided with means to hold it in connected relation to the bar when the side members are in normal position, an integral screw on the head, and means on the screw to supoprt an outlet box.

5. In an outlet box support, the combination of a supporting bar having a longitudinal slot with closed ends therein to provide longitudinally extending side members with a space therebetween, the side members being flexible so they may be spread, a head insertable into said space when said members are spread and having notches in its sides to receive said members and whereby the carrier will be held in slidable and connected relation to the bar, an integral screw on said carrier and means to support an outlet box.
