SHELF CONSTRUCTION.

Application filed May 21, 1919.

To all whom it may concern Be it known that 1, Josnrrr 1V. Srnnorr, a citizen of the United States, and residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Shelf Constructions, of which the following is a speci-' fioation, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to shelf constructions and particularly to apparatus of this class designed to be used in various manufacturing institutions and particularly 1n workshops and is used for the purpose of storing or separately classifying tools, workpieces or various manufactured parts or products, and the object of this invent on is to provide an improved shelf construction of the class and for the purpose specified which is simple in construction and strong and durable; a further object being to so construct the apparatus as to readily facilitate the adjustment of the various shelf members employed in connection with the standard or framework construction; and a further object of the invention being to so con. struct the apparatus including the shelf members thereof as to put the various parts of the apparatus under compression or under tension whereby the shelf construction will always maintain an upright or rigid position regardless of where the load or stress upon the shelves, or the shelf construction, as a whole is located, thus preventing the tilting or upsetting of the apparatus; and with these and other objects in View the invention consists in an apparanis of the class and for the purpose specified, constructed and operated as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which I Figure 1 is a front view of a shelfconstruction showing two parts or sections with a plurality of shelf members connected therewith :2 a partial section on the line 2-2 of Fig. 1 on an enlarged scale, and with parts oi the construction broken away;

Specification of Letters Patent.

Patented Dec. 16, 1919;

Serial no. 298,726.

ig. 5 a partial section on the line 5'5 of tion of one of a number of bearer-bars which I I employ. I

In Fig. 1 of the drawing, I have shownat 10 a shelf construction composed of two sections or parts 11 and 12, said sections or parts being formed by vertically arranged end standards 13 and 14 and intermediate vertically arranged standards 15. The standards 13 and 14 are arranged in the corner portions whi e the standards 15 are arranged centrally of the front and back portion of the apparatus and in line with the standards 13 and 14, and the standards 13 and 14 are connected with the standards 15 by longitudinally arranged bearer bars 16 a plurality of which are employed and which are spaced vertically on said standards, as is illustrated in Figs. 2, 3 and 4; the vertical standards 13, 14 and 15 are also connected by forwardly and backwardly directed Wall plates 17 as is illustrated in Figs. 2, 3 and 5 of the drawing. I

The above construction completes the general. construction of the framework of the apparatus which, as set out, is divided into the vertical sections or parts 11 and 12', and in practice, the plurality of shelf members 18 are adapted to be placed on the tops of the bearer bars 16 between the separate standards 1315 and 1514, and the wall plates 17, said shelf members resting upon two of the bearer bars 16, one at the front of the apparatus and the other at the back.

In practice, the standards 13, 14 and15 of the frame are preferably composed of sheet metal tubes 19 which, in the construction .shown are square or rectangular in form in cross section, and are made from strips or sheets of material the sides of which are brought together and bent at right angles to one of the sides of the tubes 19 as shown at 20 to form flanges between whichthe front and rear edge portions of the wall plates 17 are secured by riveting, spot welding or otherwise, this construction being clearly sh in F g.- 2 of the drawing. It i l'be noted that this construction or operation connects the separate pairs of standards 13, 14 and 15 and forms therefrom forwardly and backwardly directed side wall or partition members 21.

The opposite side faces of the tubes 19 are provided with a plurality of equally spaced apertures 21-, the top portions of which are enlarged as shown at 23, and these apertures are so arranged on the tubes 19 as to bring the apertures of one of the pair of standards 13 in line with corresponding apertures of the other pairs of standards 14 and 15 as will be readily understood.

The bearer bars 16 are preferably composed of sheet metal bent into U or channel-shaped form in cross section, and the upper or free sides of which are bent to form outwardly and downwardly directed flanges 21 as shown in Figs. 3 and 6 of the drawing, and formed centrally of the cross heads 25 of said bearer bars are longitudinal and downwardly directed beads 26. The opposite end portions of the bearer bars 16, or the flanges 2 1 thereof are provided with a plurality of saw-cuts or recesses 27, and the end portions of the beads 26 of said bearer bars are also provided with a plurality of saw-cuts or recesses :28 which are the same in number as the recesses 27, and are in the same vertical alinement therewith as is illustrated in Figs. 2, 4 and 6 of the drawing, and in connecting the bearer bars 16 with the tubes 19 or the apertures 22 therein, the end portions of the bearer bars are passed into the tubes 19 through the apertures 22 and the flanges 24; pass through the enlarged portions :23 of said apertures, in this operation, and the end portions of the bearer bars are then moved downwardly and the bottom walls 29 of the apertures '22 pass into one of the recesses :28 in each end of the bearer bars, while the shoulder portions 30 of the side walls of the apertures pass into one of the recesses 27 in each of the flanges Ql in the opposite ends of the bearer bars, and this as will be apparent will lock the bearer bars 16 against displacement in or against movement in the tubes 19, the beads 26 and flanges 24 forming shoulders where they are cut out or recessed at 27 and 28-, and these shoulders bear on the inner and outer side faces of the tubes 19.

The shelf members 18 are preferably composed of sheet metal and are approximately rectangular in form. The corner portions of said shelf members are cut out as shown at 31 to receive the corner portions of the tubes 19, and said shelf members are also preferably reinforced at the corner portions thereof by a plurality of corrugations 32. The front and back sides of the shelf members 18 are bent downwardly, upwardly and inwardly to form downwardly directed V-shaped flanges 33 having inwardly directed top plates 34:, which are independent of and adapted to move on the bottom of the shelf members 18 and are free to be sprung outwardly by reason of their spring connection through the inner members 35 of the V- shaped flanges 33 as shown in Fig. 3 of th drawing. W hen the shelf members are in position or placed upon the tops of the bearer bars 16, the plates 3% rest upon the tops of said bars. It will he understood that the V-shaped flanges 33 extend longitudinally of the front and back portions of the shelf members between the tubes 19. The opposite side walls of the shelf members 18 are provided with downwardly directed flanges 36, the ends of which are bent upwardly upon said flanges as shown at 37 to strengthen the same and in connecting the shelf members with the framework of the apparatus. After said shelf members have been moved downwardly to rest upon the bearer bars 16, a plurality of stove belts or similar devices 38 are passed through the flanges 36 and through the wall plates 17, this construction being clearly illustrated in F 5 of the drawing.

From the foregoing description my improved shelf construction will be readily understood, or the method of assembling the same, when taken in connection with the accompanying drawing and the following statement: It will be apparent that the standards 13, 1% and 15 made from the tubes 19 will be separately formed by suitable dies or otherwise as will also the bearer bars 16, and shelf members 18, and the wall plates 17 will also be cut to the desired dimensions and the holes drilled therein through which the stove bolts 38 are passed. With the required number of these parts at hand, to build up a shelf construction. of the class specified, or two sections or parts thereof, as illustrated in the accompanying drawing, it being understood that the wall plates 17 have been welded or otherwise connected with the separate pairs of standards 13, 14; and 15, I connect said standards with a plurality of bearer bars 16 in the manner hereinbefore set out, said bars being spaced or located vertically on said standards and in the separate parts or sections in such manner as to divide the separate parts or sections 11 and 12 into the required number of shelf spaces 39. As illustrated in Fig. 1, the spaces may be all of the same size, or of different capacities, and after all the bearer bars have been properly placed in position the shelf members 18 are placed upon the bearer bars. It will also be noted on a consideration of Fig. 4. of the drawing that the longitudinal dimensions of the shelf members are preferably slightly greater than the distance between the separate pairs of standards 13-45 and 15- 14t, whereby the proper placement of the shelf members 18 in position require the aid of a hammer or mallet blow at one side portion thereof to place said shelves in position under tension, or compression, and this as will be apparent also places the standards or pairs of standards under compression where each of the shelf members are connected therewith. In placing the shelf members 18 in position the V-shaped flanges 33 in the front and back edges thereof may also be forced downwardly over the bearer bars under the tension of the inner spring members 35 of said flanges.

The above described operation of placing the shelf members in position tends to move or force the standards, or pairs of standards 13, 14 and 15 outwardly where said shelves are mounted in connection therewith, or

i where the bearer bars are connected with said standards, and this as will be apparent will place the standards, or pairs of standards, under compression at these points and regardless of where the load is placed on the shelf construction as a whole, or regardless of what compartment or what part of each compartment the load is placed there will be no possibility of the shelf construction tipping over, or falling down by reason of the location of the weight. It will also be apparent that while I have shown a specific form of bearer bars and apertures as well as a specific form of shelf members, my invention is not limited to these or other details of construction herein shown and described, and changes therein and modifications thereof may be made, within the scope of the appended claims, without departing from the spirit of my invention Or sacrificing its advantages.
