Jam 1952 J. E. DIEFFENDERFER ELECTRICAL CONNECTION BOX Filed Feb. 4, 1946 i fa/wey Patented Jan. 8, 1952 2,581,755 ELEQIR QAL C NEC ION BOX John Elwood Dieffenderfer, Constantine, Mich, assignor of one-half to J. Harvey, Dearborn, Mich.
A pl ti n Fe eerr 4, 94.6 see! N- 4. 4 9 Claims. (Cl. 220-3-6) vantages which 'issimple and economical in its parts in assembly thereof and in manipulation.
Objects relating "to'd'etails' and economies of the invention will appear fromfthe' description to follow, The invention is defined and pointedoutintheclaims'f A structure which embodies the features of the invention is illustrated in the accompanying drawing, in which:
Fig. 1 is a front elevation of an outl t box em,- bodying my invention in assembled relation to a wallpanel.
Fig. 2 is a fragmentary View in section on line 2- 2 in Fig. 1, one' of the bracket members being shown in engaged position by full lines, the other being shown in initial position by full lines and in engaged" position by dotted lines.
' Fig. 3 is a fragmentary rear perspective view.
Fig. 4 is a perspective view of one of the mount ing brackets.
In the accompanying drawing, I represents a wall panel of plaster, beaver "board, or the like having a hole 2 therein adapted to receive the connection box 3, an outlet box being illustrated.
in this preferred embodiment I provide a pair of bracket members designated generally by the numeral 4, these being'moun'te'dbn the outer sides of opposed walls of the box. Bracket members d'are formed of sheet metal folded to pro vide an outwardly projecting flange 5 adapted to overlap the front'side'of' the support. The
forming of the range by folding thestock provides the desired rigidity with relatively light stock or stock of light gage.
The brackets are in effect angular in'jshape and have slots 6 adapted to receivethattachin screws 1. The brackets have inwardly projecting bendable arms 8, the. arms desirably having spaced weakened zones 9 'resulting from holes it. Straps l! preferably integral withithe arms are reversely folded thereon and of such length as to project initially up o n th front of the box as shown Fi gfijso that they may be grasped with pliers or other suitabletoofand a annexerted thereon would result in the bending of the arms at the weakened zones into engagement with the inner sides of the support as shown at I2 in the drawings, that is, the arms are bent outwardly to project behind the edges of the support openings and to engage the's upport in opposed relation to the flanges 5 of the brackets.
After the retaining arms have been bent'into engaging position, the ends of the straps are folded over the edges of the box" an d disposed within thebox as shown at l3. This enables the very rigid anchoring of the box in the support opening. Should it becomenecessarvto renew the box, the ends of the strap may be swung to extended position and a tool inserted to bend the arms back against the sides of the box or out of engagement with the support, permitting the box to be renewed.
My improved brackets may be very economically produced and they are very quickly andasuy manipulated for the mounting of "the box.
I have not attempted to illustrate or describe Various adaptations or modifications which may be desirable for particular designs or typ'esof boxes, as it is believed that these disclosures will enable those skilled in the art to embody or adapt my invention as may b-e'desired.
"Having thus described my invention-what I claim as new and desire to secure by letters patent is: l; The combination with a connection box, of brackets mounted on'the outer sides of opposed walls of the box and having laterally projecting support engaging flanges, said brackets having transversely spaced inwardly projecting bendable arms disposed along the sides of the box and having longitudinally spaced weakened zones, andstraps integral with and extending from the inner'ends'of the arm and reversely folded relative thereto to lie between said arms and the sides of the box and initially projecting beyond'fthe front edges of the arms'wherebyfthey may be grasped and the arms, bent outwardly relative tame box into retaining clamping engagement with a support in opposed relation to the flanges or thei'brackets by Pulling on the straps and the straps'then folded over the ed es of the box into retaining engagement therewith with'the "ends of the' straps disposed within the box. Y' '2.
