EARL F. SMITH AND GUY KENNETH WILSON, OF MUNCIE, INDIANA, ASSIGNORS TO MIDWEST METAL PRODUCTS COMPANY, OF MUNCIE, INDIANA, A CORPORATION OF INDIANA HANGER DEVICE FOR ELECTRIC FIXTURES Application filed February 7, 1929. Serial No. 838,126.
This invention relates to improvements in support-devices of the bar type used in building construction, and which are intended for electric outlet boxes, and electric service de- 5 vices such as lighting fixtures and the like.
The invention has reference especially to a support device of the kind referred to, which consists primarily of a slender metal bar adapted to be secured in position between the 10 ceiling joists or wall studding.
The objects of our invention are to provide a device of the kind described, which is economical of manufacture,'strong and dur able, and which will afford means for the suspension or support, at practically any location within the area of the ceiling or wall.
Our invention is illustrated in the accompanying drawings, and described and claimed in the following specification and claims.
Figure 1 is a side view of our improved hanger device.
Figure 2 is a top' plan view of Figure 1. Figure 3 is a view showing the position of the hanger device when the point of suspento be equidistant between the joists or studdings.
Figure 4 is a view showing an outlet box supported by the hanger bar.
0 Our invention broadly stated, contemplates the providing of a bar having angular bends therein, spaced apart, and in such relation to the ends of the bar, that oppositely extending arms and an intermediate offset body portion a eccentric thereto, are provided, and there being a connecting stud provided on the said body portion of the bar.
In carrying out the purposes of our invention, the said bar is of steel or iron, and may be one-half inch wide and three-sixteenths of an inch in thickness, and of predetermined length. At a predetermined intermediate point 1, the bar is bent upon itself. At a relatively short distance from 1 it is then bent in opposite directions, there being thus consti- .tuted the integral stud A. Thence, at relatively short distances from the stud, by slight oblique bends, and then again in opposite directions, and I thence at right angles, and thence in opposite directions, the bar will sion or support of the outlet box or fixture, is
have been fashioned into the formation as shown in Figure 1, there being the offsets B of the body portion B, the bends C and C, and the arms D and E.
The arms D and E are of. unequal lengths, and are in straight alignment with each other. In each of the said arms, spaced holes D and E are provided in the successive order, as shown in Figure 2. These holes permit the passing of a small nail or screw, for the securing of the bar to the face of the joist or studding. The stud A, formed in the manner above described, has a longitudinal slot A, the function of which will presently be referred'to. e
The only'work in processing this article, other than the bending thereof as just described, is the milling of the end, and of the corners of the stud, and then the threading of same for the accommodation of fitting. of
I standard t e or of such other t oe as ma be 7 yr desired. Threaded, and movable freely on the said stud, is the nut G.
In supplying this improved article to the trade, the bars and the nuts therefor, arepreferably packed separately, for economy and convenience in packing and handling. For the general purpose for which the article is intended, the stud is providedwith the usual standard iron pipe thread common to the fittings of electric service devices generallyfor which the invention is intended. 7
To use the invention, the bar is disposed in engagementwith the faces of the joists or studs, at position so that the location desired for the stud A is obtained. Then by a nail or nails applied through the arms D and E, the device is secured in its position. Features of the invention are the extreme simplicit of its. construction, and the ease with whic it is capableof being used for-all of the general purposes for which it is intended.
In. an instance :where the outlet box or fixture is to be supported at a location occurring equidistant between the joists or studding, the bar is secured in the position, as shownv in Figure 3. g
'If the position for the box occurs at a location to' the rightof the said central position, then the hanger is set at the position as indicated by the dot-ted lines. If the outlet occurs at a location to the left of the said central position, then the hanger bar is turned end for end, and whereby the stud is readily brought to the desired position.
The effectiveness of the support by our improved hanger bar, of the outlet box is easily understood by reference to Figure 4. T0 attach the outlet box it is simply disposed in place, the stud A protrudingfitherethrough the usual knoclnout opening in the rear side of the box. The offsets provided by the portions B and B, permit of a full thread entirely to the base of the stud, so that when the nut is screwed on the stud, the rear side of the box is secure and direct engagement with the body portions B and B of the bar.
The length of the bends C and C, in the hanger bar as illustrated in the drawing, is suitable for an outlet box having depth of one and one-half inches. For a box of this size, the device is designated as the shallow type hanger. For a box of the larger size, and which is about one and three-quarters inches in depth, a deep type hanger is provided, it being the same in all respects, as the former, except as to the lengths of the bends C and C. In supplying this improved article to the trade, the bars and the nuts G therefor, are preferably packed separately, forreasons of economy, and for convenience in packing and handling. 1
The slot A provides facility for the easy insertion into the space to be enclosed by the box, of the terminal portions of the electric wires or conductors which occur at said outlet. Another function of the stud is that it constitutes means to which the fitting of the electric service device or fixture may be attached.
What we claim as our invention, and desire to secure by Letters Patent, is'
1. Ahanger device ofv the kind described, consisting of a barprovided with a double bend in its intermediate portion, thence at a relatively short distance from the end of said double bend, being bent at angles toprovide aligned oppositely extending arms, the portion of the bar that is comprised in said double bend being threaded, and there being a nut screwed thereon.
2. A hanger device of the kind described, consisting of a metal bar bent upon itself at a predetermined intermediate point, thence, at a relatively short distance from said point, being bent in opposite directions, there being thus constituted an integral centrally slotted stud, thence, the bar at relatively short distances from the stud, being provided with shallow oblique bends, and being extended in opposite directions, thence. at. right angles, and thence again in opposite directions, whereby to provide shallow offsets adjacent the said stud, a body portion at each side of the said offsets, and oppositely extending and thence in opposite directions, the arms thus formed bein of unequal lengths, the said stud being threaded, and there being a nut screwed on the said stud.
In testimony whereof we afix our signatures.
