Dec. 15, 1959 N. A. APPLETON ETAL ELECTRICAL FIXTURE FASTENER Filed Feb. 27. 1957 INVENTORS NORTON A. APPLETON ARTHUR I. APPLETON United States Patent ELECTRICAL FIXTURE FAS-TENER Norton A. Appleton, Chicago, and vArthur -I. Appleton,

Northbrook, Ill., assig'nors .to Appleton Electric Com- .pany, Chicago, 111., a corporation of Illinois Application February 27,1957,-Serial No. 642,858

7 Claims. (Cl. 248-216) This invention relates to electrical fixtures and more particularly to a bar hanger for supporting electrical outlet boxes or the like between spaced 'wooden building members such as floor joists or wall studs.

in the co-pending application of Arthur I. Appleton,

Serial No. 597,242, filed July '11, 1956. "When installing this type of hanger, ordinarily the workman holds the hanger in position by hand while hammering nails which provide permanent fastening means, through the ends of the hanger into the wooden building members.

The general object of this invention is to provide 'a retainer for fastening an electrical fixture, such as an outlet box, in place on building joists or-studs. A'related object of the invention is to provide an integral nailing prong for fastening a member to a wooden support.

It is a more specific object of the invention to provide an outlet box support with a retainer formed as an integral nailing prong'bent such that with the fixture held against the studs or joists, the nailing prong may be given a light blow as by a hammer to drive the toe of the prong which is sharpened into the surface of the wooden members. Permanent nails may then be installed, and particularly in overhead installation and awkward ceiling work, a saving-in time and reduction in cost of installation results.

Another object is to form the integral nailing prong by striking the same out 'of flat sheet material such as is provided by the end flange 'of the bar hanger support for the box. A further object is to provide an integral nailing prong wherein the sharpened point of the toe of the prong lies substantially within the opening in the sheet material left by the metal removed therefrom to make the prong. Thus the nailing prong is protected against being broken off or bent during shipment v.or handling. Moreover, due to the pointbeing shielded or concealed, the danger of injury-to tworkmen from cuts or scratches is reduced.

,-A further object is to provide a construction' for the fixture retainer which is inexpensive to manufacture yet which is durable and sturdy so as to be satisfactoryunder conditions of rough handling to which devices of this general type are frequently exposed.

Otherobjects will appear from the-following description taken in connection with theaccompanying drawings wherein:

Figure 1 is a .perspective view of a bar hanger constructed in accordance with the present invention;

"Fig. 2 is a view in side elevation of the bar hanger shown in Figure 1, supported between floor joists or wall studs; I

Fig. '3 is an enlarged fragmentary perspective view of the integral nailing prong formed .in the end "flanges of the bar hanger of the previous figures;

Fig.4 is asectional view illustratingthe nailing prong taken through the median line of the end flange and hanger; and

Figs. '5 and 6 are views in end elevation and transverse section illustrating the end flange of the bar hanger and the integral nailing prong.

While the invention has been described in connection with the preferred embodiment, it will .be understood that it is not intended 'to be limited to such embodiment but is intended to include all modifications, alternative constructions and equivalents which are included within the spirit and scope .of the appended claims. 7

Referring to the drawings, the present invention is .shown embodied in an extensible bar hanger having telescoping sect-ions 11, ;121and a hanger stud13 which is employed for holding .an outlet box '14 or the like electrical fixture in place. This hanger stud 13 also .serves for locking the telescoping sections together so .-.as to :fix the overall length ofthe hanger.

The hanger .also .has end flanges 15a, 15b provided with openings 16a, 16b for receiving nails for permanently fastening .the hanger between wooden building members such as floor or ceiling joists or wall studs 17a, 17b as indicated generally in Fig. 2.

In carrying out the invention, the outlet box 14 is temporarily fastened in place on the joists or studs 17a, 17b by means of an L-shaped nailing prong or retainer 18a, 18b which, .as shown in Figs. 3 and 4, is struck out of deformable fiat sheet material presented by that portion of the support for the box that lies adjacent the surface of the wooden building members. In the present instance the box 14is supported by the bar hanger :which has 'end'fianges 15a, 15b lying adjacent the joists orstuds. The nailing prong 18a, 18b is therefore struck out of thexm'etal of the hanger ends, .so'that with the ends of the hanger held flat against the beam .or stud on which the hanger is to be fastened, the bent prong may be given a light hammer blow and the toe portion 20, 20b of the prong which has'a sharpened point 21a, 21b driven into the surface of the wood for supporting the'hanger. The hanger may be fixed in permanent pos'itionwith ordinary nails. It is contemplated that the nailing prongs 18a, 18b may be struck out in a punch press type forming operation, and thus at a :relativelylow cost added to the hanger construction.

For the purpose ofstrengthening the'nailingprong, as appears most clearly in Figs. 3 and 6, the shank'portion 19a, 19b and toe portion 20a, 20b thereof maybe'forrned With a slight transverse CUI'VO'SO :as to resist bendingand retain substantially the original angular relation and form. As shown in Fig. 3, the shank 19a of the L-shaped prong 18a is integral with the end flange 15a of the hanger and extends out of :the plane of the surface of the flange with the :toe portion curved :back along an are I struck from about the hinge point of "the prong as shown in Figs. 2, 4 and 6, so that the point 21a which is left sharpened from the forming die lies within the opening 22a left in the material of the flange. The point is thus protected somewhat against being bent during shipping or other handling.

To insure that the point of the nailing :prong will enter the wood of the supporting stud or joist-ata proper angle, the free end of the toe portion 20a, 20b of the nailing prong 18a, 18b is shown herein carried rso as to enter an adjacent wooden member at substantially right angles-to the face or surface ofcthe member. This angular relation is shown in Fig. 6. In order to hammer the prong into the wood, the prong should bestruck by blows directed substantially parallel to thevtoe, as herein shown at about right angles to the wooden support, .al though .the particularangle would vary according to the angle the :toeis carriedby theshank. Due to .thecurved configuration of the toe and shank, however, as the nailing prong 18a, 18b is driven into the member the point 21a, 21b of the nailing prong describes an upward curve defined ,by the are I. As illustrated in Fig. 4, with the toe portion 20a and point 21a completely embedded, the shank poriton 19a of the nailing prong lies substantially in the plane of the end flange 15a. It is a feature of the present invention that the embedded nailing prong offers substantial resistance to removal from the wood while yet enabling removal by prying as with a screwdriver or claw hammer. As will be observed, the curved nailing prong 18a under normal conditions retains substantially the same set placed in it by the forming die while it is being driven into the wooden supporting member, pivoting about its hinge without exerting substantial force on the bracket tending to shift it from the original placement on the support. The shank portion 19a on the other hand lies substantially flat against the outer surface of the wood, having lost substantially all the set placed in the prong by the forming die. The toe portion to be extracted from thewood is required to describe a curved withdrawing path which the flat configuration of the flanged ends of the bar hanger prevents. Thus the nailing prong clamps the flange to the stud or joist and temporarily yet securely holds the hanger in position. The nail openings 16a, 16b in the end flanges and on each side of the nailing prong are provided for receipt of ordinary nails which may be driven in place to hold permanently the fixture in position.

It will be readily appreciated that in installing an outlet box with a bar hanger having the retainer means of the present invention, after having obtained the adjustment in length to accommodate the particular stud or joist spacing involved, with one hand the bar hanger is held in place with the flat outer surface of one end flange against the surface of the respective floor joist or stud. The workman then with a hammer may strike the end of the hanger a sharp blow to drive the nailing prong into the wood, repeating this operation to fasten both ends of the bar hanger. Particularly in awkward ceiling work in overhead installation between joists, once the bar hanger has been supported in place by means of the integral nailing prongs, both hands are left free so that permanent fasten ing devices may also be hammered into place using the nail openings 16a.

We claim as our invention:
