DONALD H. MURPH, 01 DALLAS, TEXAS, ASSIGNO R 0F ONE-HALF TO HENRY ELMER HOBSON, OF DALLAS, TEXAS.

FAN AND FIXTURE SUPPORT.

Application filed November 5, 1913, Serial No. 799,314. Renewed November 7,

To all whom it may concern Be it known that I, DONALD I-I. MURPH, a citizen of the United States, residing at Dallas, in the county of Dallas and State of have invented certain new and use Texas, ful Improvements in Fan and Fixture Supports, of which the following is a specification.

My invention relates to improvements in fan and fixture supports or hangers, and more particularly to a device of this character to be used in connection with the common type of union box for electrical conduit installations.

The principal object is the provision of a support or hanger which is equally well adapted for use in supporting a fan or an electrolier or other fixture, and which may be installed, by providing two forms of the device, in frame or in concrete ceilings and partitions. Both forms of my invention embody the same idea or principle.

Referring to the drawings accompanying my application, Figure 1 is a sectional elevation of the support or hanger showing it as it would appear installed in a framework ceiling and for supporting an electrical fixture. Fig. 2 is a section on the line 22 of Fig. 1. Fig. 3 shows the hanger secured in the top plate of a union box, and Fig. 1 is a plan view of a ceiling plate used ,in qmnection with the hanger adjuncts. In F'g. 5 is shown the form of hanger to be uled when it is desired to install the same in concrete constructions, and for use as a fan support. Fig. 6 is a sectional view on the line 6-6 of Fig. 6, and Fig. 7 is an elevation of the form depicted in Fig. 6.

Referring specifically to the parts shown in the several views and in which, like reference characters indicate like parts, the numeral 1 is the socket or hollow casting portion of my hanger preferably of malleable iron and having the bolt hole or eye 2 at its upper end (Figs. 1 and 3), said eye being for the purpose of receiving the supporting rod or bolt 3 which is in turn secured to the joists or other frame-work of the ceiling as illustrated, for the obvious purpose of supporting the hanger .and preventing the same from turning. At the lower end of the casting and integral therewith is the externally threaded stud 4 while the under face of the shoulder portion 5 provides a seating surface for the casting against the top por- Specification of Letters Patent.

tion of'the union box 12 when the stud is inserted through the opening in the said box, after which the threaded lock nut 10 is fitted upon the threaded stud and screwed up to hold the casting firmly to the box.

The hollow in the casting is for the purpose of receiving a hollow'soft metal core or lining 6, such as lead, which is poured therein through the opening 9 in the base of the casting while in a liquid state and which upon becoming hard is prevented from turnngby the longitudinal ridges 7 in the casting. The inner surface of the core is molded with longitudinal ridges 8, (Fig. 2), which ridges may be either flat or sharp edged. The internal shoulder '11 prevents the core from pulling out. The purpose of this core may be readily understood by reference to Fig. 6 wherein the fan hook 15 having the threaded end portion 16 is shown screwed therein. By providing the aforementioned longitudinal ridges 8 it is possible for the hook to cut its own threads in the core.

Referring to Fig. 1 it will be observed that the purpose of the externally threaded stud 1, asidefrom receiving the nut 10, is to secure an insulating joint such as 13 which in turn receives a fixture or a'fan stem 17.

I have shown for the sake of clearness (Fig.

1) the method of wiring which may be used, the flexible conduits 14: connecting to the porcelain knobs 18, carried down through the openings 12 in the union box 12, through the openings '19 in the ceiling plate 20 and thence to the stem 17. Only two wires are shown but as it is sometimes necessary to bring down four wires the union box and ceiling plate are provided with the necessaryopenings 12 and 19, respectively.

In Fig. 5 I have shown the form of my invention as installed in a concrete ceiling. The hanger is embedded in the concrete and by reason of its expanded top portion 21 it will be prevented from pulling out while the ribs or flanges 22 prevent turning.

I have illustrated my invention by showing the form for installation in a framework flooring as supporting a fixture stem upon the threaded stud portion of the hanger; while that form especially adapted to concrete installations is shown supporting a fan stem by means of the fan hook screwed into the soft metal core of the casting. But it is to be understood that either the threaded stud or the internal soft metal core mav be employed for the purpose of supporting the stem members to meet varying conditions and requirements.

I particularly reserve the right to make various alterations or changes in construction of my invention as long as I do not depart from the spirit of the improvement as set forth in the annexed claims.

I claim:

1. A device of the character described, consisting of a socket portion, means for securing the said socket portion to a supporting structurc,'a seating surface in the base portion of the socket, a tubular threaded stud integral with the said base portion, a hollow soft metal core retained within the hollow portion of the said socket portion for the purpose of receiving a threaded member, and a threaded nut for engaging the said threaded stud.

2. A device of the character described, consisting of a socket portion, means for securing the same to a supporting structure, means for preventing a rotating movement of the device with respect to the supporting structure, a seating surface formed in the base portion of the socket, a tubular threaded stud integral with the said base portion, a threaded locking nut for engaging the said stud, a hollow soft metal filling or core retained within the said socket for the purpose of receiving a threaded member, and means for preventing turning of the said core within and with respect to the said socket portion.

3. A device of :the character described, consisting of a socket portion, a supporting rod receiving portion integral therewith, a

seating surface at the base portion of the socket, a tubular threaded stud integral with the said base portion, a locking nut for engaging the said stud, and a hollow soft metal core retained within the said socket portion for the purpose of receiving a threaded member.

4-. A device of the character described, consisting of a socket portion, means for securing the said socket portion to a supporting structure, a seating surface in the base portion of the socket, a stud integral with the base portion, and a core retained within the said socket portion for the purpose of receiving and retaining a depending supporting member.

5. A device of the consisting of a socket portion, means for setcuring the same to a supporting structure, means for preventing a rotating movement of the device with respect to the supporting structure, a seating surface formed in the base portion of the socket, a threaded stud integral with the base portion, and a threaded locking nut for engaging the said stud.

6. A device of the character described, consisting of a socket portion, a supporting rod receiving portion integral therewith, a seating surface at the base portion of the socket, a threaded stud integral with the said base portion, and a locking nut for engaging the said stud.

In testimony whereof I affix my signature in presence of two witnesses.
