' isclaims. (o1. 24S-Q19).

This invention relates to shelf bracket construction or the like.

One of the objects of this invention is to provide a simple and thoroughly practical bracket construction for supporting a shelf or the like, that Will be of rugged construction and reliable action. Another object is-to provide a construction of the above-mentioned character which is inexpensive to manufacture and capable of simple and'rapid adjustment, attachment, or manipulation in practical use. Another object is to provide a shelf bracket construction Vin which the attachment of the bracket to its supporting member maybe quickly and dependably achieved and,

y moreover, in a manner that will be free from causing marring or defacement of the supporting member. Another object is to provide a simple and thoroughly practical and inexpensive assembly of the bracket per se with its manually operable securing device or devices.

. Another object is to providea construction of theabove-mentioned nature which will be compact and neat and well adapted for use particularly in display cases, and which will have-a `Wide range of exibility of adjustment to meet the varying requirements of practical use in. such a showcase, without, however, causing defacement or marring when the position of the bracket is changed. Another object is to provide a bracket construction that will be adjustable and capable of being decorated, for example in colors, as by paint, enamel, or the like, but constructed so that rearrangement of the bracket with respect to its supporting member will-notaifect the nish or decoration of the parts. Other objects Will be in part obvious or in part pointed out hereinafter; Y The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts as will be -exemplied in the 'structure to be hereinafter described and the scope of the application ofV Which'will be indicated in thefollowingclaims. j

Similar reference characters refer to similar parts throughout the several views in the draw-- ings.

As conducive to a clearer understanding of certain features of my invention, itmight at this point be noted that bracket constructions have heretofore been employed in which the vertically extending support for the bracket is provided with so-called keyhole slots or openings into which suitably shaped pairs of projections on the bracket itself are received; these keyhole slots are unsightly and ungainly in appearance and have certain other objections among which may 'be noted that they do not permit the achievement of suitable decorative effects, particularly by way of the application to the vertical members of colored paints, enamel, or likecompositions. It has also been proposed to employyertical supports for brackets and to provide these vertical supports with slots into which certain parts' of the bracket are to t; but with known methods of securing the brackets to such slotted vertical supports, it has been found impossible to achieve such decorative effects as are above-mentioned witho-ut causing the cracking off, scratching, or marring of the applied coloring material. One of the various aims of this invention'is t0 achieve a construction in which such disadvantages vas the above are avoided in a thoroughly practical and inexpensive manner.

Turning first to Figures 1 to 5, there is shown a bracket generally indicated atr 20 and its verti'c-al support, generally. indicated at 21'.` The preferredforrn of support 2l is a sheetmetal channel-shaped ymember having a front face 21? and. side flanges 2lb and 21C, the member .21. being adapted to rest with the edges of the side flanges against a wall or like member and to be'secured thereto in any suitable manner. The front face 21a is provided with vertically extending alined but spaced slots 23, 24, 25, 26, etc. (Figure 2). These slots can be made relatively narrow and are therefore relatively inconspicuous throughout such portions of the support 21 as are exposed between vertically spaced brackets carried thereby. The outer or exposed faces of the front face 2la and of the side anges 2lb and 21c can be nished in any suitable manner; they may be, for example, given any suitable plating or polish, or they may be colored as by the application of a suitable paint, enamel, or other appropriate coloring material.

In the embodiment illustrated in Figures l-ll, the bracket 20 takes the form of a casting of a suitable metal and may be made of any suitable weight or strength or shape, but it preferably comprises a horizontal arm 2()n with a downwardly and rearwardly extending bracing arm 2Gb, the left-hand or rear ends of the two arms being joined by a vertical portion 2GC (see Figures 1 and 3). The vertical portion 2()c may be suitably anged to either side, as at 20d (Figure 3) and its end face 2()e suitably made plane, thus to provide a suitable expanse of surface to rest against the front face 21ZL of the vertical supporting member 2l and to appropriately square the bracket oil if the engaging surfaces of these two parts are dependably held in assembled relation.

Secured to the lefthand portion of the bracket 20, as viewed in Figures 1 and 3 and in a manner to be more clearly described below, is a sheet metal member 27, the shape and coniiguration of which is better shown in Figure 5. Member 27 may conveniently be a stamping out oi sheet metal of suitable weight and it is provided with two hook-shaped parts 27a and 27b and it has a transversely extending slot 28 of different widths; thus, the portion 28a of the slot 28 has a greater width than the portion 28.b which in turn is of less width than the spacing between the free end of the hook 27a and the inner or anchored end of the hook 27h. Also, the plate member 27 is provided with suitable apertures, illustratively two in number, which are shown at 27c and 27d in Figure 5.

The plate member 27 is centrally received within a suitable recess 20f (Figure 1) appropriately formed in the vertical left-hand member 20C of the bracket 2() so that the hook parts 27a and 27b project rearwardly or to the left from the rear face 20e of the bracket 20 (see Figures 3 and 4) but the end part 2()c is provided with a transversely extending slot 20g (Figures 3 and 4,) shaped 'substantially as shown in Figure 3 and through which the slot portions 28 and 28b of the plate 27 (Figure 5) are exposed.

This recess 20f may be formed in any suitable way. .For example, I may mill the recess aiter the casting 20 has been completed and may insert theplate 27 either with a driving iit or give it a 5. suitable snug fit, in the latter case employing riv- 6 ets or the like that pass through the side wall portions of the recess 20f and through the openings 27C-and 27d in the plate 27 or, instead of milling the recess I may core the recess during the casting of the bracket 20 and then insert the plate with a driving t or else otherwise and then secure it as by rivets, or both. Also, I may, in the process of casting the bracket, suitably position the plate member 27 in the mold to cause it to function as a core and then cast the metal, the metal iiowing around the plate 27 and entering also suitable recesses such as the openings 27c and 27d, thus securely anchoring the plate 27 in the desired position. I may thus use any suitable metals; for example, I may use brass or bronze for the bracket 20 and a suitable steel for the plate 27. Also, I may weld the plate 27 in position within the recess 20f.

Thus, I provide the assemblage better shown in Figure 3 in which the hooks 27@L and 27O are well shown projecting to the left of the end face 20E of the bracket 2() while the lips 27e and 27f (see Figure 5) that form the narrower portion 28h of the slot 28 project toward each other be yond the facing walls of the narrower portion of the slot 20g, as is better shown in Figure 3.

Into the Wider portion 28a of the plate 27 I then place a knurled nut 29 preferably provided with a lett-hand screw-thread; then I provide a member generally indicated at 30 (Figures 1, 3 and 4) that has a relatively large head 30EL and a threaded shank 30h, the latter being preierably provided with a left-hand thread and adapted to be threaded into the nut 29. The head 30EL is provided with two diametrically opposed and longitudinally extending slots 3()c and 30d, better shown in Figure 4, into which are recessed respectively the, lips 27e and 27f of the plate 27. The member 30, after the nut 29 has been positioned as above described, may then be slid in an axial direction toward the right as viewed in Figure 3 to bring the lips 27e and 27r into the external slots 30c and 30d and then by rotating the nut 29, the device 30 and hence its head 30L may be brought into the position as shown in Figure 3. By reason of the congura- At its left-hand end and coaxial therewith, j',

the head 30c is provided with a cylindrical projection 30e (see Figures 3 and 4). This projection has such a dimension and the parts coacting therewith are so proportioned that, While the hooks 27at and 27lo may pass freely through two vertically displaced slots in the support 2l, such as the slots 26 and 25, respectively, the projection 30e is in substantial alinement'with the upper end of the slot 25 (in which the hook 27D has been received) when the bracket 20 with the hooks is dropped so that the hooks engage in back of the wall 21a of the Vertical support 21.

If now the nut 29 is rotated in an appropriate direction, the device 30 is moved to the left and ultimately the parts assume the position shown in Figure 1; the nut 29 abuts against the righthand end wall of the slot 28 in the plate 27 or against the right-hand end wall of the slot 20g in the bracket 20, the head 30a, presenting at its left-hand endanend face of relatively large area, is moved squarely against the front face of the wall 2l2L of the channel support 2l, and the projection 30e enters the extreme upper end of the slot 25 through which the lower hook 27b has been passed. f Y

Appropriately tightening up the nut 29 thus l But it is toV be noted that j' the head 30a 'is brought about. Thus, marring of the nish or decoration of the parts is dependably prevented.

Ihe projection 30e prevents intentional or accidental upward movement of the bracket (see Figurel) rvso that accidental dislodging'of 'the bracket 20-irom its vertical support cannot take place. Disassembly of the parts, however, may readily be achieved by rotating the nut 29 in reverse direction, thus drawing the clamping head a directly 'away from the support 21 and'again avoiding marring of the nish on the vertical support 21.

In Figures 6, 7, 8 and 9'I have shown a possible modied embodiment of certain features of my invention and I have there illustrated a bracket'generally indicated at 31 made up of a sheet metal member of suitable weight and strength and having a horizontal shelf-supporting portion'31a and a vertical portion 31b adapted to rest against the wall 21a-o the support 21, the strap metal being of appropriate width to form an adequate area of surface to abut against the front face of the vertical support 21; the parts 31a and 31h, thus bent at right angles to each other, are reinforced and held in that position by a bracing member 31c which extends diagonally substantially as shown in Figure 6; the bracing member 31c may be of round stock and may be'riveted or welded or otherwise secured as at 31d and 31e to the portions 31a and 31h, respectively. l

The vertical part 31b is provided with a centrally positioned vertically extending slot 31f of sufficient width to receive therethrough certain partsvof a plate member 32 not unlike, in many respects, the plate 27 above-described in connection with Figures 1 5. The plate 32, preferably in the form of a stamping of Ysheet metal such as steel, is given a shape substantially as shown in Figure 6 but better shown in Figure 9.

The plate 32 (Figures 6 and 9) has two hook-4 shaped partsr 32a and 32h, the over-all length (in a vertical direction as viewed in Figure 9) of which is substantially equivalent to the length of the slot 31f so that the hook portions of plate 32 may be passed lfrom the position shown vin Figure 9 to the position shown in Figure 8, shoulders 32c and 372d on the plate 32 abutting against the righthand aceof the bracket portion 31b while the hooked portions 32a and 32b are thus positioned, as is better shown in Figure 8, to be passed through slots, such as slots 26 and 25,V respectively, in the supporting member 21. Preferably, also, I provide ears or lugs 32?v and 32g (Figure 7) cut and bent atk right angles to the plane of the plate 32 and extending from' opposite sides'thereof, these lugs having their lefthand faces as viewed in Figure 8 preferably alined with theleft-hand faces of the shoulders 32C and 32d and being thus adapted to abut against the right-hand face of the bracket portion 31h. These lugs aid in maintaining the plate 32 at right angles to the bracket portion 31h.

. Plate 32 is provided with a slot extending crosswise of its center portion, the slot having a relatively'narrow portion 32h"and a relatively wide portion 321'; the latter receives the nut 29 described above in connectionwith Figures 1-5 while the inwardly projecting walls of the former formguides for the slotted'headl 30a of the device 39; the threaded shank"30b is received within the nut 29,'the parts 32, 29 and 30 thus holding themselves automatically in assembled relation. In Figures 3 and 9 these parts are shown assembled but with Vthe head 30@L .drawn substantially completely toward the right.

In rline with the movement of the head 30a toward the left, as viewed in Figures 8 and 9, the slot Blf is enlarged to provide a substantially circular opening 3lk so that the head 30e, when moved toward the left, as viewed vin Figure 8, upon manipulation of .the nut 29, may pass through the bracketportion 31" for coaction with the portion'21a of the vertical channel support 21.

The plate 32, with the parts 29-30 related to it, may be associated with the bracket 31 in various ways. For example, the plate 32 may loosely fit intoror through the slot Slf in the bracket portion 31h, or I may proportion the parts so that plate 32 is force-tted to the bracket portion 41h. Or, I may otherwise rigidly secure these parts together as by welding, for example; thus, I may spot `weld the lugs 32f and 32fg to the bracket portion 31". l

In any of these cases plate 32 with its associatedparts 29-30 and the bracket 31 appear substantially as is shown in Figure 8, from which it will be seen that the hooks 32a and 32b are in readiness to 'be passed through two of the slots in the vertical support 21 so that, upon a subsequent downward movement of the assemblage withrespect to the channel support 21, the hooks take in back of the front wall 21*l of the support 21, as is better shown in Figure 6.

A subsequent rotationof the nut 29 is then made' elective to movethe head 30a in a direction toward the left and to cause it to abut against the front face of the wall 21a of the channel support 21 with the projection 30e entering the upper of the lower of the two slots throughwhich the hooks have been passed. The nut 29, abutting against the right-hand vertical wall of the slot 32d, in coaction with the threaded shank 30h, thus causes a secure clamping of the wall 21a of the support 21 between the hooks 32e--32b and the head 30a itself, while the projectionv 30%3 dependably'pre'vents accidental displacement of the bracket in' an upward direction.

In Figures 10 and 11 I have shown another possible embodiment of certain features of my invention and in these gures I have shown a bracket '3 3 made of a suitable heavy and strong sheet metal and thus capable of being stamped; the bracket 32 has a preferably horizontal upper edge 33a and is tapered or curved as is indicated at V33b so as to give a substantial vertical width at its left-hand endwhere it is to be attached tothe supporting channel and a relatively small vertical dimension at its right-hand end with corresponding rigidity and strength to carry the load imposed upon it.

At its left-hand end it is shaped substantially as is best shown in Figure 10 to provide two hookshaped parts 33c and 33d and a longitudinallyex tending and substantially centrally positioned slot 33 terminating ina wider slot 33f. Within the latteris received the nut 29 whilethe inwardly projecting wall portions of the former-form guides for'the slotted'head 30e of the device 30 already above-described. As was the case with respect to the mcdications above described, the nut 29 holds the Apart ,391 against sliding out of the slot 33e while the sliding or channeled interengage-A ment between the head 30a and the inwardly projecting'parts of the slot 33e p-reventsthe head 30a with the nut 29 from falling out of the slcts in a direction transversely to the axis of the device 30 itself. x Y

- The hooked parts 33 and 33d are passed through two slots, such as the slots 26 and 25 of the member 31, whereupon the bracket 33 is moved downwardly so that the two hooks will take in back of the front wall 21a of the channel 21. The nut 29 is then rotated to force the head 30a against the front face of the wall 212L and to bring the projection 30e into the upper end of the lowermost of the two slots, the latter action preventing the bracket 33 from being moved upwardly and thus from being, in that way, disengaged from the support 21. The nut 29, as in the other modifications described above, is rotated to a sufficient extent to clamp the vertical wall 21*L oi the support 2l between the hooks 33C-33d and the head 30ct with the requisite or desired pressure.

. With the constructions above described, it will be seen that I have achieved a high degree of simplicity of construction and action, together with thorough dependability oi' result. The constructions are inexpensive and it will be seen that the various objects hereinabove noted, together with many thoroughly `practical advantages, are successfully achieved. Moreover, it will be seen that certain features of my invention :readily meet the varying conditions of practical use or requiren ment; more'speciiically, it will be noted that I have hereinabove illustratively set forth the embodiment of these certain features of my invention with three of the various kinds or types of bracket shapes or structures that are most in demand.

It will also be noted that the assembly and disassembly of the bracket with respect to its vertical supporting member are readily and conveniently achieved and, moreover, without the need for special tools and without causing harmful or undersirable marring or marking up of coacting surfaces. I am thus enabled to employ any iinish such. as plating, painting, enameling, or the like, without danger of permanently disguring the finish in case the bracket is shifted from one position lengthwise of the vertical channel support to another. The head 3o@ of the device 30 provides a relatively large area for clamping contact with the wall 21a so that the pressure per unit area is relatively small while at the same time the bracket is properly alined and held at right angles to the wall 21a. Moreover, it will be seen that the construction is of simple and inexpensive manufacture and lends itself readily to quantity production.

As many possible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawings, is to be interpreted as illustrative and not in a limiting sense.
