ATTORNEY Patented Feb. 8, 1938 UNITED STATES PATENT OFFICE 4 Claims.

My invention relates to improvements in shelving, particularly to an adjustable shelving which can be readily set up and dismounted in any desired plurality of sections for use in refrigerators, stores or for any other, similar purpose, and it is the principal object of my invention to produce a preferably metallic shelving, the individual parts of which are so connected and interconnected, that their article supporting trays can be suitably distanced from one another on their supporting posts by means of suitable brackets of a special construction attached to said posts on which the individual trays arefirmly supported.

Another object of my invention is the provision of an adjustable shelving of comparatively simple and inexpensive construction, yet durable, and highly eflicient in use, and which is sanitary as it can readily be cleaned. It may be set up in several sections which may either be aligned and connected or be angularly disposed to one another in which case specially and suitably designed brackets are used to support the ends of the inner tray bars without the necessity of using special fastening means.

. Still another object of my invention is the provision of an adjustable shelving the trays of which are supported on specially constructed brackets adjustably secured to the supporting posts or standards which are preferably made of angle irons and to the upper and lower ends of which brackets are removably attached and provided with suitable openings for the passage of fastening means to secure the posts firmly to the upper and lower walls of refrigerators or like casings with which the shelving is to be used.

A further object of my invention is the provision of an adjustable shelving made in units of identical construction adapted to be set up end to end and at their meeting ends supported by specially constructed posts or standards to which the head and foot parts are readily connected while specially constructed brackets are adjustably secured to the posts intermediate their ends to support the trays of two adjoining units.

A still further object of my invention is the provision of an adjustable shelving, the single units of which when set up and connected form a compact whole and a rigid structure to support the trays having preferably grill or grate form the individual members of which are securely held on the frame bars of the trays.

These and other objects'and advantages of my invention will become more fully lmownas the description thereof proceeds, and will then be specifically defined in the appended claims.

In the accompanying drawing forming a material part of this disclosure:

Fig. l is a top plan view of an adjustable shelv- 5 ing constructed according to my invention, two of the units of the shelving are shown in alignment while a third unit is illustrated angularly disposed to the aligned units.

Fig. 2 is a fragmentary side elevation of the 10 adjustable shelving according to my invention, partly'in section on line 2-2 of Figure 1.

Fig. 3 shows in perspective views details of an angular post and the end and intermediary brackets adjustably to be secured thereto. 15

Fig. 4 is a perspective detail view of a bracket adjustably to be secured to an intermediary post to support trays of two adjoining sections of the shelving.

Fig. 5 shows in perspective views a bracket for 20 the support of the inner tray bar of a shelf section angularly disposed to another section, and the manner of supporting the grill bars on the frame bars of the trays.

As illustrated in Figure 1, the individual sections or units of my adjustable shelving are designated A, B, and C respectively of which sections A and B are shown in alignment, While section C is angularly disposed to section B.

Each of the sections or units comprises the 30 vertical corner posts It! substantially made from angle ironv essentially L-shaped in cross-section. To the upper and lower ends of these posts are attached the upper and lower end brackets H and I2 respectively by engaging the upper and 5 lower edges of the posts in the slots l3 formed between the vertically disposed bracket branches l4, l5 depending from an upper branch plate It if the bracket is used for the upper end of the post and upstanding from said plate if the bracket is to be used as a foot. Plate I6 is perforated, as at I! for the passage of suitable fastening means for securing the brackets to the upper and lower walls of a refrigerator etc. The brackets l l and I2 are held in place on the posts 45 by means-of the screws I8 or the like passing through the branch I4 of the brackets and engagingthe post.- t g The intermediary tray supporting brackets for the corner posts as shown in Figure 3 are designated l9, and are each provided with the slots 20 into which engage the side edges of the post to be locked in their respective adjusted positions by means of the screws 2| passed through the branch. of the bracket in which the slot is 2 7. formed and engaging the post. The other branch 20' of the bracket has the form of a plate and serves to support the trays which may be firmly held thereon by means of fastening means passed through openings 23 in these plates 20. The trays of the shelving are substantially in the shape of grills or grates 24 having supporting bars or frames 25 provided at their upper edges with suitable depressions for the reception and holding of the grate bars having preferably the form of strong wire convoiutions 26- engaging the. depressions 21 in the frame bars 25 as indicated in Figure 5.

If two units are placed end to end, as shown in Figures 1 and 2, intermediary posts are used between the units which are substantially T-shaped in cross-section and top and foot brackets 29, 30 having slots for the engagement of the ends of the posts port the posts 28 on top and bottom walls of their respective casings and the posts are secured with their ends in these slots by means of screws 3| or the like, 7 V

In Figure 4 I haveillustrated the brackets used for the support of the" trays of two aligned. units, generally designated 32'havin'g each a horizontally disposed plate member 33 and a. member depending therefrom. The plate member as well as the depending member'has a slot 34 formed therein into which engages the edge 35 of the T-post Z8 and is held therein by means of the screws 36 or the'like, whilei-angularly disposed upright flanges' 3l are engaged by the frame bars 25 of the trays which maybe held in place by means of suitable fastening means passing through the openings 38 in plate member 33.

In Figure' 5, I have illustrated a bracket 39 for the support of the'inner end of thetray frame bar 25 of a section C, angularly disposed to a section B of the shelving, asfor instance illustrated in Figure 1, the frame bar '25 of the secticn C rests upon thefibottom of a chamber 40 formed in the bracket 39, The other branch of the bracket is separated from the chamber 40 by means of a channel 4| into which engages the frame bar 25 of the next adjoining section B to which the unit C is anguiarly disposed, and screws 42 or the like hold the bracket 39 in place on the'grate frame bar 25 of section B.

For the support of the outer frame bars 25 of the traysof section or unit'C posts 10 and ,l I are used at the outer corners with brackets H, l2, while similar brackets 30 are used to adjustably hold the outer ends of the supports for the trays on the edges 35 of posts 28.

The operation and use of my adjustable shelving willbe entirely clear from the above description thereof by having simultaneously reference to the accompanying drawing, and it will be entirely clear that by loosening the screws l8v the upper and lower brackets H and I2 of'thecorner posts can be removed, while by the loosening of the screws 2 l" the interme'diary brackets l9 holding and supporting'the trays can be adjusted at any distance from one another on the posts l0 and 28 to vary the distance betweenthe individual trays tosuit the size 'ofthe articles'to be supported thereby. The brackets 32Ysupporting two adjoining units of the shelving can likewise suitably be adjusted bymeans'of the screws 3li,'while the upper ends of the post s-I 0 and28, can be securely held in position by means'of the brackets H and 29 respectively which may be secured to the walls of a refrigeratoror'other casing for the shelves. If one or several units are angularly 28 are provided to sup- 1 shown the preferred form of my shelving only as an example of the many possible ways to practically construct the same and thatI'ma'y make 1:

suchchanges in the general arrangement thereof and in the construction of its minor details as come within the scope of the appended claims without departure from the spirit of my invention and the principle involved.

Having thus described my invention, what I claim as new, and desire to, secure by Letters Patent is:
