ATTORNEY Patented July 15, 1952 UNITED STATES PATEN OFF CE v CABINET STRUCTURE Charles 0. White, New York, N. 17., assignor to White, Cabinet Corporation, New York; N; Y., a corporation of New York Application March 17, 194:5, Serial No. 583,310

modities or implements is desired. The instant invent on deals principally with the structure of a cabinet per se while at the same time bring ing out the adaptability or mytype. ofcylindrical cabinet to oombinationsbuilding up to a complete kitchen, pantry, or other combination.

Moreover, certain or the basic features of my cabinet are applicable equally as well to. suchconstructions as refrigerators, stoves, broilers, and instrument, cabinets, as'they are to a common storage cabinet, hence the term cabinet when and as used herein is to. be understood as used in an illustrative rather than a limiting sense. a

Cabinets as previously employed had many drawbacks. In the first placeit was the' common practice to make most of them either square or rectangular be'cause it was believed that. greater storage space was thus obtained and because such cabinets fitted the space. normally. available for them. In order to increase their capacities, however, they were often made of such a depth that it was practically impossible to get at things stored in the back part of them, or on the back part of their shelves, without removing everything in the'iront. The back space was thus of little value and was usually not used at all.

The hinged doors of prior art, cabinets were both a nuisanceand a hazard. They projected out into the room when open and had to. be closed after each opening to avoid ones bumping into them andinjuring oneself, or even to use the space that they-occupied when open. Rarely, if at all, were stoves or refrigerators supplied in shape orsize so related to the rest of th Gabinets that all could be fitted in together to make, a complete kitchen out offharmonious units of elements. 7 I

In the few instances in the past where. cabinets w-ith cylindrical exteriors were employed, they were usually awkward, were permanently fixed in place and precluded any modification without rebuilding. The prior art mounting of cylindrica sh lv was u a qm wte l pensiv and, s q c ns ml with a en er Pole ingmeans. Finally, no one had the vision; to conceive ofv a whole kitchen or pantry made up f t an eable cylindrical elements Rat the prior practice called possibly for one cylindrical cabinet amongst a numberoi rectangular ones. where it was obviously out of place.

In addition to. curin th defects of the prior art constructions, the cabinets of my invention go several steps. forward in cabinet development.

In the first place, all of the elements of the same size, whether stove, refrigerator or mere storage cabinet, are interchangeable with one another. All normal types of cabinets made in accordance with my invention, can be used with either end up. This is particularly advantageous when righthand as against left-hand doors are desired. Furthermore, a cabinet of one height may be replaced by a series of cabinets oflesser height-whose total height equals that. of theori in l cabinet-v T i Where kitchens are :concernedenables the building up of complete kitchensto suit the, tastes of the users thereof as toposition, capacity and convenience of the various elements such asgordinary storage cabinets, refrigerators, stoves and broilers. When the desired elements are all selected, the complete kitchen is mounted on its own supports'which are independent, ofcthe. wall of the building and can thus be easily installed, removed, or changed; Most of the details of such installation form no part of the instant application.

The independent, cabinets of my invention, as

already mentioned, areas readily useable. with one end up as with the other. In accomplishing this, I have'reduced the number of parts to a minimum and simplified the constructionby making parts of each cabinet interchangeable" with other parts of the same cabinet. The doors of my cabinets are cylindrical and turn inside the main cabinet wall to 01 6 so that they are outer the way. The shelves are interchangeable and'the intermediate sh elij or shelves are adjustably and pivotally Q WZQQ 2y asil ????1213 uno rus ve m a 1H5 d n ly anjq est q mvm enti n to pr v e qyl ndr qal a t c n iru z i es f W ap ca i t It is another object of my invention to provide such cabinets which are readily interchangeable, onewith another, and can be readily combined,

0 one with another to form combinations of various heights and sizes. a

It is another object of my invention to provide such cabinets whose storage space and accessibility are kept at a maximum;

or. pivot beingcornmonly employed as the mount- Still another object of myinvention is provide such cabinets which are useable either end up and are fully interchangeable, regardless of which end is up.

A further object of my invention is to provide such cabinets whose construction is simple, economical and foolproof.

A still further object of my invention is to provide such cabinets with interior elements which are adjustable and useable with equal facility, no matter which end of the cabinet is up:

A still further object of my invention is to provide such cabinets so constructed that the parts a and assembly thereof canbe formed-and per formed by simple operations employing unskilled labor.

Other and further objects of my invention will become apparent as the description of the in-, vention proceeds and by reference to the accompanying drawings in which:

It will be noted from a study of the accompanying drawings that in some of the views no attempt has been made to include all of the detail which might have been shown by dotted lines and the like. Such detail is, however, shown independently and in enlarged views as -well as in views which show sufllcient of each portion of an individual cabinet to show how the detail fits into the construction of the cabinet as a whole. It is believed that this manner ofpresentation will. expedite a study of the drawings and the understanding of the invention.

Figures .1 and 2 are included principally to furnish background and to give one example of the combinations to which the cabinet units of my invention may be put. No attempt has been made to go into precise detail in these figures. Their purpose is merely to illustrate generally how such as a complete pantry or kitchen installed in a room'would look were all of the cabinet units employed made in accordance with this invention. The manner in which the cabinet units are assembled into vertical sections forming groups of'cabinetsor into an assembly comprising combinations of such sections and the manner in which such an assembly is removeably mounted in place within a room without being physically attached tothe' walls of such room, involve inventions in and of themselves. It is not the province of this application to treat with such inventions,'so that the detail of them is omitted herefrom.

In the Figure 1 showing, I- have illustratedthe combining of larger lower cabinets, such as 5 and 6; with 'shorter cabinets such as 'l and '8-to make a section of the same height as achieved by putting together two intermediate length cabinets, 9 and I0. Further, it is to be noted that the doors of the cabinets 5 and 1, as indicated by the finger grips thereof H, operate in reverse direction to those shown in Figures 6 and 8. In similar manner, various combinations of smaller upper cabinets such as l2, l3, l4 and I5 can be combined andlarranged to provide any suitable combination.

Extra large end cabinets such as shown at l6. l1 and i8 may similarly be combined or reversed as desired. As an alternative, one of these ends couldbe madeas a single cabinet extending throughout the'full height of the section. Such cabinets are commonly employed for the storage of long, unwieldy articles such as vacuum clean- Finally, Figure 1 also shows perforated kick plates such as l9 and 20, on which the cabinets are mounted. The particular structure and purpose of these is treated elsewhere.

In Figure .2, I have shown somewhat schematically the manner of tying the cabinets together and mounting them in a room without making them. a. part of that room. Generally speaking the cabinet units arezmounted on, and supported .the manner of finishing offithe whole construction toblend into a room." This'is. done bythe use of end pieces. 25' extending from the end cabinets, and scribed to the Wall. These are about the only elements of the whole construction which must be made to conform to the walls of. the room.

To illustrate the structure of a specificcabinet, which structure is the essence of this" invention, I have selected one. of the more simple forms employed, but one which incorporates all the basic elements of, my invention. Such. a cabinet is that shown at 9 in Figure l and in the perspective View of Figure 3. Not all the. detailsof the cabinet unit appear in Figure. 3, but'those, which do not are morefully developed in the subsequent views.

Cabinet uni-ts made in accordance. with my invention will preferably be made. of metal, as it can be. readily worked into the, forms desired. Other materials may, of. course, be employed where suitable, so I do not wish to be limited to metal for the construction of all or any particular part of my cabinet.

Considering, first the. side and end walls of the cabinet unit and themanner in whichthey areinterengaged, the vertical. sidewall 26 forms a substantial portion of a cylinder, leaving out of course a section providing for the opening into the cabinet; The wall 26 thus terminates in the spaced-apart sides 21 and 28; of the, wall opening. The ends of the wall are planes at right angles to axis of the cylinder. Beinghoth the same,

these ends are readily receivable by identical end members 29 and 30 The employment: of identical end membersnot only saves labor and materially simplifies the assembly of the cabinets but this is one feature which assists materially in enabling the cabinets to beused with either endup.

The end membersZQ and 30 being identical, only one need be described. Generally they are in the form of a disc-like base portion 3I provided around its periphery with an offset embossed channel 32, shown best in Figure. 11, which channel is generally U-shaped in cross section. The bottom portion 33 of the channel 32 of substantial width and is. generally parallel with the base portion 3!. From. the bottom 33, the. wall of the embossing turns directlyupwardly to. form the engaging wall 34. This wall extends at right angles tothe base portion 3! backto the plane of the same and terminatesin an out-turned bead portion 35. Thus as clearly seen in Figure 11, when the side wall 26. is en aged with an end member, the portio'nl36 of thewall 25, adjacent the free end thereof, is 'suppfortedby the wall 34 and is received in.the turned-over bead'or lip 35.

The base portion 3|, asshown in Figures and 12, has a hole punched in its center at?! and is embossed inwardly therearound, at 38, to form a shallow depression. The embossing 38 receives a fitting 39 whose base is received in the embossing and is held in place therein'by means such as the screws shown. The fitting 39 has a center hub This cylinder, however, is of'ashorter; radiusthan that of the outside of the cabinet and (as seen from Figures I0 andll) than that of; the embossing 32 around: the endmembers. Thus the door is free to swing from opento closedposition within the cabinet. Y

I have found that a simple and effective construction for the door is to form the sameout of spaced concentric sections, 44 and es, of lightweight material. These sections 44 and 3-5 are kept spaced apart but secured togct-herby means of flanging the side edges of each section in opposed d-irections and overlapping such flanges as shown at 46 -41 and 48-49.: Screws are then passed through the flanged portionsiasfshown in Figures 14 and; 15. The flanging 2.17 4.8, however, as best shown in Figure 14, is first bentdown wardly with respect to the sheet 44 before itis turned back inwardly] to form the: portion 48. This outwardly turned portion 50 serves as one part of a stop and closingconstruction to limit the movement of thedoor in one direction and to close what might otherwise be a vertical opening at that point; i. v

The door is pivotally mounted and additionally supported by means 0f identical sets of radial arms 5f, Stand 53 which converge' inwardly to 'ends turned at right angles to the body portions thereof and extended for a short distance inwardly between the sections M and 45, as shown at 55 in Figures 10 and '12. In addition, the exterior arms 51 and 53 which meet the door just within the flanged over edges thereof are interengag'ed by the samev screws which, are employed to hold together the flanged over ends 56 with 41 and 48 with 59. It is of course to be understood that the pivotal mounting and support for the ends of the door are identical so that the same construction canbe used at either end.

As a means for operatingthe door, I have found that all that is necessary is a depression or finger hole such as that shown at H in Figure 16. It is merely an embossing in the outer sheet and the use of any additional element is thus obviated. Furthermore, I have also found that no latch or catch mechanism is necessary to hold doors of this type inclosed position, for they stay where they are put.- Since these doors operate around inside of the cabinet, they are never in the way.

doors as theilast step in, the clearing up operation.

Though the instant cabinet is shown as one having merely two shelvesone atthe bottom of the cabinet and anotherone which is mounted opening 31, andtherearound. Their maximum diameter is such that when mounted centrally of the cabinet they will, as shown in Figure 5, be free to turn just inside the inner section 45 of the door 43.

The tray 51 is secured to a supporting member such as the spider 59, which terminates in a central hub 60 for the pivotal mounting of the tray in the bearing provided therefor. The hub 60 is also furnished with a laterally extending surface 6| designed to engage the upper surface of the mounting member to steady the shelf. The mounting of the shelf at the bottom of the cabinet, is readily accomplished as shown in Figure 10, by inserting the hub 66 into the pivotal recess 4| which is designed to receive it. Merely placing it there is sufllcient, as would also be true were it to be engaged in the like mounting at the opposite end of the cabinet, assuming the cabinet to be the other way up. The hub 60 is similarly receivable in the pivotal mounting of the mounting member for the intermediate shelf or shelves to be described hereinafter. Here also, provision is made for additional steadying of the shelf by providing a receiving surface for the surface 6|.

In order to stiffen the cylindrical wall 26 and to take care of several other requirements, the cabinet is provided with vertically extending stiffener members 62, 63, 64 and 65 shown in detail in Figures 17 to 24. Considering, first, stiffener member 62, which is located at the left side of the cabinet opening as viewed in Figure 3, it is seen that the same is a bar of material somewhat heavier than the wall of the cabinet.

This bar lies against the outside of the wall 26, extends throughout substantially the entire lugs 66 extending laterally from the inner surface thereof. These lugs, 66, are appropriately spaced from the ends of the member 62, so that when that member is brought up against the side wall 26 with the lugs 66 extended through apertures in that wall, they will underlie the bottoms 33 of the annular embossings 32 around the bases 3| of the end members. The lugs 66 are provided with screw threaded bores to receive screws 61 passed through registering holes in the portion 33. Obviously this construction serves to stiffen and strengthen the side walls of the cabinet and at the same time positively secures the ends of the cabinets in interengagement with the sides thereof. Additional stiffener members 63, 64 and 65 are similarly provided with lugs 66 identical with the lugs 66 of member 62 and which similarly receive screws 61 to assist in holding the ends and side walls of the cabinets in assembled relation as well as strengthening the side walls.

As already pointed out, stiffener member 62 lies against the outside ofthe side wall 26 of .the cabinet. At the same position another member is secured against the inside of the cabinet wall and is secured to both the cabinet wall and the stifiener member 62 by some suitable means such as a rivet. This memberhas a base portion 68 lying against the inner face of the wall 26 and a stop portion 69 extending inward from the wall 26 at right angles thereto. From the innermost extremity of the stop portion 69 this member extends in a reversely bent part 10 to a position outside of the cabinet, where it terminates in a back-turned securing lip H. The securing lip H is designed to be adjacent to a comparable member on the next cabinet and be engaged by means employed to join the cabinets together. This joining feature is not gone into further in this application. The member 6869-10H extends throughout the full height of the cabinet as shown in Figure 3. Other important functions that it performs are in its part 69 acting as a stop for engagement with the stop shoulder formed on the door to limit the movement of the door in closing direction and also as a seal to close the crank which might otherwise appear between the outer surface of the door and inner surface of the wall.

The other side of the opening is similarly provided with a stop and securing member having a. portion 12 secured to the inside of the wall 26 at the position where thatwall is supported on its exterior by the stiffener 63. Here the right angle internally extending abutment 'member 13 extends further inward of the cabinet than does the stop member 69. The portion 73 is also reversely bent and folded against it self for a distance equal substantially to the width of the door. This folded portion serves as an abutment for the leading edge of the door to stop it when it reaches fully closed position and to form, with the edge of the door, a seal to provide a complete closure. From the reversely folded portion 13 the member extends outwardly of the cabinet wall to form portions 10 and H, identical with the portions 10 and H previously described. Before leaving this feature, it is to be noted that the backw'ardly extending portion H lies substantially on a tangent to the horizontal diameter of the cabinet as viewed in the Figure for 5 positions. Thus the portion H is readily available for the join ing of its cabinet to an adjacent one.

Another important feature of my invention is noted from the showing in Figures 6, 18, 19 and 20. Here the stiffener members 63, 64 and 65 are seen to be equipped with additional sets of lugs extending through the wall of the cabinet and for a, short distance within the same. The stiffeners 63 and 65 each present a series of four evenly spaced lugs to which the reference characters 14, 15, I6 and 11 are applied in each instance inasmuch as they are identical and are similarly located with respect to the vertical extent of the stifi'ener members. These lugs serve as engaging means for the transverse arm of a cantilever member, about to be described, which is employed for the mounting of the intermediate shelf. They cooperate with a set of three lugs 18, I9 and extending from the spacer member 64, which lugs are designed to engage the center portion of the cantilever member referred to. It is to be noted that each of the lugs 18, 19 and 80 is positioned intermediateof a pair of the lugs 14, 15, 16 and 11. The purpose of such positioning will appear presently.

The cantilever shelf mounting member, shown by itself in Figure 8, and in mounted positions in Figures 5, 6 and 7. has a center member Bl whose T8, '19 and 8B.

,o he

inner}- end is provided withrapivotal mounting .82 to' receive the hub I60, go'f fa' rotatable-shelf member I s already described. f, The outer end jof portioniii-l is provided iwi'than' upwardly extending pin 83', and, just a little in and from thejpin 83, the member 8|.[i's also ,pitov'dedfwith' laterally extending armsideandtfi; '.Thse arms have their end surfaces 86 'and '8-11formed to the contour of the inside of the 'wall25. The pin 83 is of a size to be accommodated by vertical bores 38, 89 and 98 formed in and extending through the three lugs It is believed that from the showing-in Figures 5, 6 and "7., .it will be:'appa'rent how the cantilever shelf mounting member 8! is employed.

Obviously, the arms 84 and-I85 will have to be supported from beneath by borrespondin'g' pairs to 'allowan adjustment of the shelf mounting member to any one of thr eefjdifferent positions,

regardless of which end of the cabinet is up.

Assuming then that it is desired to install or adjust the position of the intermediate shelf,

all that need be done is grasp the cantilever member 8| and slightly raise its end 82 while at the same time bringing the ends 86 and B! of its cross member down on top of a pair of lugs, such as 15, on the members 63 and E5 respectively. Inasmuch as the end 82 is tilted upwards the end carrying the pin 83 is thus below its normal level, and the pin 83 will thus pass beneath the lug 18. A rocking of the end 82 downward will seat the pin 83 in a bore 88 and enable the surface of member 8| around the pin 83 to engage the under side of the lug 18 at which time the shelf support will be in horizontal position. To remove member 8! and adjust the shelf to a different position, it is merely necessary to tilt the end 82 upward and repeat the process, engaging the ends 86 and 81 and the pin 83 with whatever related lugs are selected. Obviously this mounting, removal and adjusting of the cantilever shelf mounting member 8| can be accomplished with equal facility regardless of which end of the cabinet is up. It is not even necessary to remove the shelf from the mounting 82 in order to do this, but the housewife or other user of the cabinet would probably find it easier to manipulate the shelf mounting member without the shelf in place. Though I have shown one specific form of cantilever member, it is of course obvious that such member can be formed in different ways and still embody the principle underlying this feature of my invention. Before leaving the discussion of this feature of my invention, it is to be particularly noted that my cantilever shelf mounting construction, though providing ample strength for the support of articles placed on the shelf, and providing an entirely adequate mounting for a detachable, rotatable shelf nevertheless reduces to the barest minimum the amount of storage space in the cabinet taken up by it. Furthermore, the construction of the mounting member of the lugs for supporting it and of the shelf itself, are extremely simple in construction, as well as in operation. They are accordingly economical to member :10. ,At this point the'end 'fl 8 of the door make and lend themselves to every-day use without in rodu in stream ine compli ions- Another function perform'edfbvthe stiffener n en ilier" 4 audit l s V o 111s t a t as a to p or the d or 43 W eelie-5 i en a a as it is inte d d l I The member P eet o e e .1110 may just as theiingergrip H arrives 'at the abuts against 'the luigs -14 toil. Thus a proper positioning "of an existing "memberiisall-that is needed. to assure the performance of a function which would normallycallfor-the useof an addi- 'tional'member,

From the foregoing it-will 'be readily apparent that I *have devised a cylindrical cabinet unit so complete yet so simple and economical that ;i-t; goes farinadvanceof any cabinet construc- ;;tions whether cylindrical or-n0t, heretofore c ontemplated. Furthermore; and somewhat spite of its extreme simplicity andeconomy, my cabinet memb'er notbnl'y lends itself admirably to combination -wi-th ;or' interchange with counterpartsofvarying sizes, but also combines admirably in-to vertical sections of similar cabinet units andassembliesconsisting of several of such vertical sections.

While, as --alrea"c;ly po n-teotout, any --invention has :been considered from the point of view of its use in a kitchen or as part of a complete kitchen, and also has been considered as an ordinary storage cabinet, it is of course to be understood that such has been done merely for the sake of convenience of illustration. The cabinet is useable in many situations and locations other than kitchens, and the basic features of its construction are readily adaptable to other fields such as, but without limitation to, refrigerators, stoves and broilers. Other changes and modifications which could be made without departing from the spirit of my invention will become apparent to those skilled in the art, and I therefore desire that only such limitations shall be placed upon my invention as are found in the appended claims.
