Referring more in detail to the accompanying drawings, the reference character 20 designates an upright support upon which shelving brackets 2| and 21a are .adjustably mounted.

The upright support 20 as shown more clearly in Figures 5 6, 8 and 9, is of tubular or channel formation, rectangular in formation and having a rear wall 22, side walls 23, spaced front Walls 24 with an inwardly directed flange 25 at the free edge of each front wall 24 with the inner edges of the flanges 25 notched as at 26 to provide seats for lateral pins carried by the shelving brackets 2| and. 2|a. The spaced walls of the notches 26 are slightly inclined upwardly and rearwardly for the more secure seating of the shelving brackets, as shown in Figure 6.

The shelving bracket 2| is shown in Figs. 3 and 6 comprises a horizontal arm 21 and a vertical limb 28, the bracket being of one-piece construction and of blade-like form. Laterally directed pins 29 are carried by the upper end of the vertical limb 28 and when the vertical limb is disposed in the upright channel member 20, the pins 29 are seated in selected notches 26.

A tilting screw arrangement is associated with the lower end of the vertical limb 28 and the up right channel support and as shown more clearly in Figures 6 to 8, comprises a plate 30 flatly engaged with one side of the lower end of the vertical limb 2B and carrying end lugs 3| reversely bent to overlie the opposite face of the lower end of the vertical limb 28 as shown in Figure 6. An offset tubular member or barrel 32 is carried by the plate 30 and extends transversely of the vertical limb 28 and said barrel has a transverse opening intermediate its ends that registers with a similarly formed opening 33 in the vertical limb 28. A nut 34 extends into the opening in the barrel 32 and also projects into the opening 33 in the vertical limb while the screw 35 freely movable through the barrel 32 is threaded to the nut 34 and forms an interlocking connection between the tilting screw plate 30 and the vertical limb 28 of the bracket. The screw 35 is provided with a relatively large head 36 and constitutes the tilting screw for the adjustment of the horizontal arm 21 of the shelving brackets 2| and 2|a. With the shelving brackets in position in the upright channel support, the tilting screw head 36 projects outward ly of the support and forwardly of the front wall 24 thereof and said tilting screw head 36 'is adapted to be engaged with an abutment strap 31 of .U-shape as shown in Figure 8 that straddles the forward side of the upright channel support and is provided with a lower end opening slot 38 to facilitate placement thereof on the upright channel support rearwardly of the tilting screw head 35. Upon operation of the tilting screw 35, the shelving brackets 2| and 2|a are shifted on their pivot pin mountings 29 for the correct positioning of the horizontal arms 21 thereof.

From an inspection of Figures 6 and 7, it will be observed that the tilting screw 35 is positioned laterally of the vertical limb 28 of the shelving bracket and another. form of tilting screw which positions the same in the plane of the vertical limb 28 of the bracket is shown in Figures 16 to 18. The lower end of the vertical limb 28 of the shelving bracket is provided with side notches 39'and a lower end notch 40. A U-shaped clip comprising side plates 4| and 42 is placed upon the lower end of the vertical limb 28, the plate 42 being cut away at its corner edges as at 43 and shown by dotted lines in Fig.

16, thesecut-away portions registering with the side notches 39 in the vertical limb while the plate 4| of the clip carries lateral lugs 44 at its free corners that are adapted to be bent for reception in the side notches Hand to overlie the plate 42 as illustrated, this connection securing the clip element of the tilting screw upon the lower end of the vertical limb. The outer end of the clip is in the form of a tubular barrel 45 that carries the side plates 4| and 42 and said barrel is provided with a transverse opening inter mediate its ends for the reception of the nut 46 that extends into the end notch 49 in the vertical limb, the tilting screw 47 freely passing through the barrel 45 and threading through the nut 46 and provided upon its outer end with a relatively large abutment head 48. The foregoing tilting screw arrangement presents the tilting screw in the plane of the vertical limb 28 of the shelving bracket.

A saddle 49 of U-shape in end elevation is received upon the upper side of the horizontal arm 2'! of the shelving bracket, being bolted or otherwise secured thereto as at 59 and provided with laterally directed flanges 5! at the lower ends of the sides thereof for the support of the adjacent ends of shelf boards, the shelf boards being of a thickness to present the upper edge of the saddle 49 in the plane thereof. The flanges 5| of the saddles 49 are provided with key-hole slots 52 to receive lug pins depending from the shelf board for the anchoring of the latter to the flanges, but it is to be understood thatother forms of fastening means may be provided. The shelf boards are designated by the reference character 53.

To retain the shelving brackets rigidly positioned upon the upright channel support, there is provided a spring clip or spacer shown in detail in Figure 14 and comprising a pair of legs 54 carried by a loop head 55, one of the legs being'longer than the other to facilitate placement thereof upon the bracket. The spring or spacer clip has the legs 54 thereof straddling the horizontal arm 21 of the bracket between the forward side of the upright channel support 29 and the adjacent end of the saddle 49 and when so disposed, movement of the shelving bracket relative to the upright channel support is prevented,'the spring clip acting to prevent displacing movement of the pin support 29 relative to the notches 26. When it is desired to vertically adjust the shelving brackets 2| and 2|a with respect to the upright channel support 20, the spring or spacer clip is disengaged from the bracket whereupon pins 29 may be moved further rearwardly into the upright channel support to be displaced from the notches 26 so that the vertical limb 28 of the bracket may be shifted in the upright channel support and the pins 29 positioned in a selected notch 26. The spring or spacer clip is then replaced and the shelving bracket is again rigidly mounted upon the upright channel support.

The saddles 49 are desired for the support of shelf board ends and it is also intended to employ the form of shelving bracket 2! shown in detail in Figure 15 for the support of shelf boards intermediate their ends. The bracket 2|a is provided on the upper edge of its horizontal arm 2111 with a laterally directed angle flange 5| a and the shelf boards are suitably anchored thereto. The bracket 2|a is provided with laterally directed pins 29a for the support thereof in flange notches 26 and the vertical limb 23a of the bracket is provided with a slotted opening 33a, side notches 39a and an end notch 49a to facilitate attachment thereto of either form of tilting screw arrangement shown in Figures 6 to 9 or Figs. 16 to 18.

The several upright channel members of a unit may be connected by brace bars, as shown in Figs. 10 and 11, the connection between the upper ends closedby avertical flange Slisprovidedtvith an indenture 58 to receive a finger 59 struck-out from the vertical member 51 to retain the angle clip in position against displacement. A brace bar or rodfiilis secured atits ,endsto the horizontal fiangesfifi of theangle clips. The upright supports are further connected by brace bars 60 intermediate their upper and lower ends by means of angle clips, each including a horizontal flange BI and a depending flange 62 the latter being provided with lower end opening notches 63 tapering toward their upper ends and communicating with cross slots 64 'topermit positioning of an anchor screw in either end of the slot for the rigid mounting of the angle clip The brace rodor bar 60 is anchored atits ends to the of the horizontal flanges 6|. V

Perpendicular brace boards 65 each has an end thereof positioned in the lower end of the upright channel support and anchored therein by transverse fastening elements 66 and said boards 65 have secured to their upper edges a lower rigid shelf board 61 and a front end finishing board or panel 68. The adjustable shelving brackets and support may be used for original installation, but it is primarily intended that they be employed for replacement work and in such instances, the upright channel support may be anchored in any convenient manner to a wall and a front finishing panel 69 positioned between adjacent upright supports and substantially in line with their forward edges as illustrated in Figs. 10 and 11 so that the upright supports are hidden from view except for the forward open sides thereof.

From the above detailed description of the invention, it is believed that the construction and upper sides use thereof will at once be apparent and while there are herein shown and described the preferred embodiments of the invention, it is nevertheless to be understood that'minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
