To all whome't may concern:

H. LEVENE,

.Be it known that I, Annmrr a citizen of the United States, residin in the city and countyof Philadelphia, tate of Pennsylvania, have invented a new and useful Core or other Rack, of which the following is a ification.

My present invention comprehends a novel construction of a core rack for carrying plates with sand cores or molds into ovens. It is so arranged that the bars forming the shelves of the rack are readily re- .movable by simply elevating them. This permits the quick changing of the spacing between the shelves to allow for larger cores or molds. The removable shelf bars are interlocked in such a manner that they can-- not move laterally or longitudinally for such movement would shake and spoil the sand cores.

The rack is constructed preferably of structural metal in such a manner that a very rigid construction is provided.

The rack of my present invention can be employed as a rack per 86 which is adapted to be transported by means of an elevating truck or the corner posts may have secured to them rollers or antifriction devices, in order to facilitate its movement from one place to another.

My invention further comprehends novel means for 'adjustably securing the cross beams to their support and a novel construction and arrangement of interlocking structural beams or bars which interlock in such a manner that any lateral or longitudinal relative movement of the parts is prevented and the position of these structural beams may be readily adjusted in accordance with the character of material which is to be carried by the rack.

construction and advantage will hereinafter more clearly appear in the detailed description.

For the purpose of illustrating my invention, I have shown in the accompanying drawings preferred emments of it which in practice will give satisfactory. and reliable results. lt is, however, to be underonly and that the various instrumentalities of which my invention consists canbeYvariouriy arranged and organized and that the. invention is not limited to the precise ar-i 4 rangement and organization of these instrumentalities as herein set forth.

Referring tothe drawings.

1 designates the corner posts which consist of structural metal bars and as illuslower cross bars consisting of angles as shown which are bolted or otherwise secured to the corner posts 1. In order to reinforce sai bars gusset plates 4: are employed which stood that these embodiments a arlegjixed to the bars 3 and also to the lower structural metal bars 5 which latter as shown are in the form of angles which are adjustblyconnected to the corner post 1 by means fr fs t enimg devices exce t the interm- .diate-c ross bar 5, see Fig. which is secured to the bars 3 by means of gusset plates 7 and any desired type of fastening devices.

such as bolts or rivets 8,

The upwardly extendlng flange 9 of a bar 5 is provided with a series of spaced recesses 10, the contour of which varies in accordance with the type of structural bar which it is to receive and I prefer to illustrate it as adapted to receive the T-bars 11, see Figs. 1 and 3 which are provlded wlth the slots 12 opening through the bottom face of the web of the T-bar so that the bottom wall of the slot 12 will rest on thewall 13 of a recess 10 while the flanges forming the head of the T- bar will rest on the walls 14 of the recess 10.

On the inner face of the angles 5 an angle 15 is secured which is provided with an aperture 16 which registers with an aperture 17 in the web of the T-bar 11 so that a fastening device 18 such as for example a bolt and nut can be employed to rigidly connect the bars 11 with the angles 5. The corner posts 1 have fixedly secured to them near their u per end the bars 19 by means of usset pliates 20 and fastening devices 21. 1xed to the bars 19 are the cross bars 22 which as illustrated in Fig. 1 are in the form of angles having connected to them the structural bars 23 in a similar manner to that already described in connection. with the bars 11 and the angles 5.

The corner posts 1 have ad ustably connected with them by means of fastening devices 24 a series of superimposed structural bars 25 which as best seen in Figs. 1 and 2 are illustrated as consisting of T-bars having spaced recesses 26 therein corresponding in contour to the type of structural cross bar 27 which they are to receive and for purposes of illustration, I have shown the struc tural cross bars 27 as consisting of a T bar except that the uppermost T-bar 25 is provided with a series of double slots 28 to receive the channel bars 29, see Figs. 1,9 and 10. The channel bars 29, see Fi 10, are provided with the slots 30 and t e wall 31 between the slots 28, see Fig. 9, is preferably slightly lower than the upper face of the upwardly extending flange of the T-bar.

Instead of employing the structural bars 25 of a T-shaped contour, I may employ a channel bar of an desired contour. In Figs. 11 and 12, I have shown a U-shaped channel bar 32 the flange 33' of which is higher than the flange 34 and the web of the T-bar 27 is provided with a series of slots 35 which permit 'the flange 33 of the U-bar to be engaged by the head of the Tbar while the slots '36 have their bottom wall restin on the flange 34 of the U-bar.

In ig. 14, I have shown interlocking bars as consisting of two channels each flange of which is provided with slots 37 and 38 arranged in airs in a channel bar 39 which can be use in lieu of the bars 25 while the upper channel bars 40 WhlCh can be used in lieu of the bars 27 are provided with slots I 41 and 42 arranged in airs.

It will be understoo from the foregoing that in all the embodiments of my invention as herein shown, the adjustable bars such as 27 which form the shelves of the rack can be readily removed wlhenever desired or placed in position and when in position they interlock with the rack bars 25 in such a manner that any relative lateral or longitudinal movement between such parts is prevented.

The side walls of the slots 12 in case a T- bar is employed, as seen in Fig. 3, extend on both sides of the flange of the structural bars 25 so that any relative longitudinal movement of the bars 11 with respect to the bars 25 is prevented. The head of the T- bars 11 or 27 which are seated preferably substantially flush in the

slots

10 or 26, respectively, prevent any lateral or relative movement ofsuch bars. When it is desired to change the position of a

bar

27 or 29 all that it is necessary to do is to elevate it and move it into register with the desired slots and then lower it to adjusted position or any of such bars can be entirely removed if desired.

It will be understood from Figs. 11 and 12 that when the interlockin rack bars are in the form of a T-bar am? U-bar as shown, any relative or lateral movement of such rack bars when interlocked is positively prevented and the same holds true in the case of the bars seen in Fig. 14 and also in the case of the channel bars and T-bars in Fig. 8.

It will be apparent that the interlocking structural metal or other bars such as 25 and 27, 22 and 23, 32 and 27, or 25 and 29 form the shelves ofthe rack and can be readily adjusted without the use of tools to vary the size or shape of the shelves, in order to adapt them to the character of the material which is to be supported on the rack and while the rack is especially adapted to be used as a cross rack, it will be apparent that it can be used for any desired purpose.

It will now be apparent that I have devised a new and useful core or other rack which embodies the features of advantage enumerated as desirable in the statement of the invention or the above description, and while I have, in the present instance, shown and described preferred embodiments thereof which will be found in practice to give satisfactory and reliable results, it is to be understood that the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention,-what I claim as new and desire to secure by Let ters Patent, is

1. In a rack, corner standards, latera ly extending structural metal bars supported by said standards and having upwardly directed flanges provided with "IT-shaped recesses opening through the tops of the flanges, and T-bars disposed at an an. 1e to said bars and seated in the recesses 0 said flanges, said T-bars having their webs recessed to fit over said flanges, whereby relative movement of said T-bars with respect to said flanged bars except in an upward direction is prevented.

2. In a rack, corner standards, laterally extending structural metal bars supported by said standards and having upwardly directed flanges provided with recesses opening through the tops of the flanges and structural metal bars disposed at an angle to said first bars and adapted to seat in said recesses, 'said recesses in said flanges conforming to the contour in cross section of said second bars, said second bars having recessed portions which fit over said flanges, whereby any movement except in an upward direction of said second bars with respect to said first bars is prevented.
