Description
Ndv. 7, 1939. J. G. KNIGHT DOOR BUCK SUPPORT Filed April 23, 1937 Patented Nov. 7, 1939 UNITED. sra'rss.
snrENT orries DOOR BUCK SUPPORT be used equally well with door bucks of different sizes and adjusted to support the switch box or other element at the desired location in the wall.
1 Further objects are to provide a buck support,
which will be of particularly simple and inexpensive construction, easily assembled, readily mounted, adjusted and secured and which will occupy small space in shipment and storage.
20 The foregoing and other desirable objects are attained by novel features of construction, combinations and relations of parts hereinafter definedand broadly claimed.
The drawing accompanying-and forming part ofthe specification illustrates certain practical embodiments of'the invention, but it will be appreciated that the structural form may be modifiedand changed all within the true intent and broad scope of the invention, as claimed.
20 Fig. 1 is a perspective view of one of the supports.
Fig. 2 is a broken part sectional horizontal View taken through a wall and door buck and showing the structure of Fig. 1, as in use therein for sup- .35 porting a switch box, outlet box, conduit, or the like.
Fig. 3 is a broken part sectional view as taken on substantially the plane of line 33 of Fig. 2.
Figsland 5 are similar views illustrating the 40 feature of shortening the support to adapt it to smaller size bucks.
Fig. 6 is an enlarged broken sectional detail as on substantially the plane of line 6--6 of Fig. 3.
4.5 Fig. 7 is a similar View of a modification.
Fig.4; is a broken part sectional view similar to Fig.3, showing a modified form of the support.
The form of the device shown in Fig. 1, consists of two lengths of strap metal II], II, se- 50 cured together in relatively spaced relation by having approached portions l2, of the same fastened by through rivets l3, and slotted lengthwise at M, in their intermediate portions to slidingly receivea bridging nut piece l5, carrying 55 a screw rod IS. The end of this rod is shown as. having a swivelled thrust connection at ll, with a thrust bar 3, of channel cross-section. It will betnoted the spacing of the slotted intermediate portions of the bars H], H, is suflicient to freely pass the screw rod [6. One or both 5 ends of the nut piece l5, may be turned at an angle as indicated at Hi, to slide over the outer face of one or both these bars to prevent turning of this nut piece when the screw rod is relatively rotated. 10
Door bucks of typical cross-section are representedat ZiL'in the several views and Fig. 2 in particular shows how the support is mounted by locating'the generally parallel bars It, II, in edgewise engagement back of the spaced buck l5 flanges 29, with the free end of the screw rod projecting outwardly away from the buck and then turningthis rod untilthe thrust piece i8 engages the back or inner wall of the buck. Ordinarily, suflicient pressure may be developed to firmly secure the: support in position by simply turning therod by hand, but if considered desirable, pliers, pipe wrench or other tools may be employed for relatively spreading the cross bars andthrust piece sufficiently to firmly lock the 5 support in position in the buck. The thrust piece distributes the pressure so developed to prevent injury to the. inner wall of the buck and similarly the spaced cross bars distribute pressure suificientlyto prevent injury to the buck flanges. The edgewise disposition of both the cross bars and the channel-shape thrust piece enables these parts to take alldeveloped pressure without bending or giving way.
As will be clear from Fig. 2, the screw rod. may 5 be adjusted more or less toward either one or the other surface of the wall 22, through the sliding of the nut piece l5, in the slots I4, to locate the switch box or other supported structure 23, in proper relation to theplaster line. Screw clamps, such as illustrated at 24, may be employedufor securing'boxes such as 23, conduit clamps 25, or the like, in various positions lengthwise on the rods iii. H
Figs. 2 and 3 illustrate what may be considered a large size buckand'in which instance, the spacedcross bars extend substantially straight across the full width backof the buck flanges 2|.
Figfi may-be considered as showing a medium size buck in which the distance back of the buck flanges is much less; In sucha case, to fit the supportback'of the flanges, it is only necessary to spread or relatively separate the spaced end portions of the bars H], II and thus to foreshorten the total, overall length of the bars sufiiciently to go in that lesser space.
Fig. 5 represents what may be considered as a much smaller or smallest size buck. To fit the 5 support in this much lesser space, the ends of the two bars may be fully separated, in fact, be bent substantially at right angles to the general longitudinal axis of the support.
The bars l0, ll, may be of mild strip steel, which can be readily bent by pliers or like tools and such bending is facilitated by the previously bent condition of these strips at 26, where they are offset toward each other to bring them flat together at the points of riveting.
The nut pieces it may be made of similar strip steel, since they only require a few screw threads and have only a relatively short distance to bridge across the slotted intermediate portions of the two bars.
Instead of slotting the bars and sliding the nut in such slots, the nut piece may be made as a yoke embracing the bars substantially as indidicated at ita in Fig. 7, with one or both ends of such yoke angled inward as indicated at 21, 5'to hold this yoke in sliding position on the bars.
The construction shown in Fig. 8 illustrates the fact that the spaced bars may be made of one continuous length. Here the bars are designated Alla and Na and are shown integrally connected 'at one end by a loop 28, which may be spread as much as considered desirable to give the bars a wide bearing on the back of the flange. In
such construction, the angled ends l9 of the nut I piece it, sliding in slots it, serve to prevent separation of the intermediate substantially parallel parts of these integrally connected bars and in this construction, as in the preceding, the ends of the bars may be relatively spread to shorten the structure for smaller size door bucks.
The face-to-face relation of the generally parallel spaced bars and the relatively transverse disposition of the sliding nut piece bridging the same serve to locate the bars in the edgewise relation back of the buck flanges and the screw rod extending horizontally when the support is engaged in the buck. The malleable or bendable character of the bars and the relative separability of the ends of the bars,'enable ready shortening to fit smaller sized bucks. Instead of being made up fully extended for maximum length, the bars may be partly bent, that is, separated to an intermediate extent as for medium sized bucks, Fig. 4, in which condition they may be squeezed or hammered together to extend them fully as in Fig. 3, for larger sized bucks or may be further spread as in Fig. 5, to fit a smaller sized buck. As another alternative, the supports may be made up fully spread as in Fig. 5, ready to be bent out more or less to fit larger sized bucks.
The adjustability to fit different sized bucks is particularly advantageous for adapting the support to bucks which have only very narrow marginal flanges 21, for in such cases, the ends of the support may be bent one way or the other, so as to engage fully behind such narrow flanges. The separation of the ends of the bars also is desirable in furnishing relatively wide bearings at the opposite ends of the support providing a desirable firmness in the mounting of the support in the buck. The two forms of the invention shown, illustrate the point that the cross bars may be separate pieces secured together as by rivets or the like, as in Fig. 1, or portions of one continuous strip, as in Fig. 8. In this latter form also, the bars may be separate pieces, riveted or otherwise suitably secured together. Various other modifications and changes may be made, as will be clear from the scope of the claims.
