P 1947. W.-T. HORMES I MOUNTING FOR SLIDING D OOR FRAMES Filed Aug. 25, 1944 Patented Sept. 30, 1947 UNITED. STATES PATENT OFFICE MOUNTING FOR SLIDING DOOR FRAMES William T. Hormes, Catonsville, Md. Application August 25, 1944, Serial No. 551,167

This invention pertains to store-furniture cabinet unit containers of the type in which slidingly mounted glass doors are arranged to close the front of a unit. Such a unit container is illustrated and described in a pending application filed August 20, 1942, Serial No. 455,481 which has become Patent No. 2,367,124, dated Jan. 9, 1945, to which reference is made for purposes of illustration only.

One of the objects of the invention is to provide Simple and effective means for releasably mounting a door-supporting frame within a store-furniture unit container which is to be equipped with sliding doors, A further object is to provide a door-frame mounting of the character mentioned by means of which the frame may be vertically adjusted within said unit, after the frame and its mounting have been installed. A further object is to provide a door-frame mounting of the character mentioned by means of which the position of the frame may be so adjusted as to bring its front face in alignment with the front edges of the end walls of the cabinet unit container. Another object is to provide a door-frame mounting which may be quickly installed or removed at will, with a minimum expenditure of time and labor.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings:

Referring to the drawing C designates a storefurniture cabinet unit container which may be of any desired or well known construction. A store furniture cabinet C of the character disclosed and claimed in a co-pending application Serial No. 455,481, has been selected for purposes of illustration and without intent to limit the invention in this particular, As shown in the pres- 8 Claims. (01. 312-189) ent drawing, the cabinet C is provided with a base lo, a top H, two ends l2, and a back 13, all assembled to provide a complete cabinet structure open at the front. Unit container inserts are preferably removably positioned within the cabinet C, and are normally retained therein by molding strips M removably attached to the front edges of the end walls [2, in a manner not shown in detail in the present drawing, but fully shown and described in the above identified application, to which reference is hereby made. The end walls l2 are provided with vertical channels M in which are located slotted strips l5 for receiving removable lugs to support shelving. These strips and lugs may be of any desired construction, but

it is preferred to employ the arrangement illustrated in a copending application filed August 20, 1942, Serial No. 458,480.

Two doors D are mounted in overlapped sliding relation within a door-carrying frame F which is positioned adjacent the front of the cabinet C. Said frame is constructed with two parallel channels l6, Ilia, one for each door, and arranged to provide a rectangular structure of proper dimensions to be inserted into the front of the cabinet. The frame F is adjustably mounted within the cabinet by mountings A which are connected to opposite vertical sides of the frame.

Each frame mounting A consists of a supporting plate 20 which is provided at one end with oppositely disposed ears 2|, having screw threaded openings 22 therein, said ears being joined to the edges of the plate by reenforcing flanges 23. The lower edge of said plate contiguous to the other end thereof is provided with a plurality of horizontally spaced notches 24, positioned to selectively register with a slotted strip l5, and to be engaged by a lug 25, which may be selectively and releasably engaged with any of the slots in said strip. Fixedly attached to opposite sides of the frame F and to the inner surfaces thereof, are frame-carrier members 21, each provided with oppositely disposed cars 28, having opening 29 which are positioned to register with the openings 22 of the plate 20. Rotatively mounted in the openings 29 are the reduced ends 30 of a screw threaded rod 3|, the threads of which engage the threads of said openings 22, The reduced ends 30 of said rod 3| provide the latter with end shoulders which engage the inner surfaces of the opposite cars 28, so that said rod is held against longitudinal movement although free to rotate. The upper end of the rod 30 is provided with means by which it may be engaged by a suitable tool to effect rotation thereof. For

purposes of illustration and without intending to limit the invention, a slot 32, to be engaged by a screw driver is shown for this purpose. v

In practice, the plate 20, frame-carrier member 21 and the screw 3| are assembled in the relation shown in the drawing, and the frame-carrier member of each mounting A is spot welded or otherwise attached to a side of the frame F, in the manner hereinabove described. When it is desired to install a door frame F, lugs 25 are engaged with the strips H5 at the approximate horizontal plane to be occupied by the lower edge of the plate 20. As the frame F is inserted into the front opening of the cabinet C, one of the notches 24 of each plate 20 is engaged with its lug 25. In this manner each plate 20 is removably anchored to its end wall I2, and the two plates will sustain the weight of the frame at the opposite ends of the latter. After the frame mounting is so installed relative pivotal movement of the frame-carrier 21 and the supporting plate 20 is prevented; In this connection, it is to be understood that the lug 25 will be engaged with a selected notch 24 which will place theframe F in such a position that its front face will be in alignment with the front outer edge of the adjacent end wall l2. Then by rotating the shaft 7 3|, the reaction member 2'! will be caused to travel upwardly or downwardly, according to the direction of rotation of the rod 3!, so as to correspondingly adjust the frame F to its required juxtaposition with respect to the under face of the top H of the cabinet C. It is contemplated that molding M will be removably attached to the'front edges of the end walls 12 of the cabinet unit container, and so positioned as to overlap the ends of the frame F after its final positioning in the manner illustrated in a pending application Serial Number 455,481,

The advantages of the invention will be readily understood by those skilled in the art to which it belongs. For instance, it will be observed that a very simple and inexpensive door-frame mounting is provided for a store furniture unit, which mounting is capable of firmly supporting said frame in its operative position. An important advantage is that accurate location of the door frame with respect to the cabinet opening is assured, because of the possibility of readily adjusting the position thereof after its initial installation. Another advantage is that the mounting is so constructed and arranged that it permits of quick installation of the door frame, or ready removal thereof, as occasion may require.

If; is to be understood that although only two I frame mountings A have been shown and described, the invention is not limited in this particular, because any desired number may be used, depending upon the size of the door frame to be installed.

Having thus explained the nature of the invention and described an operative manner of constructing and usin the same, although without attempting to set forth all of the forms in which it may be made, or all of the forms of its use, what is claimed is:
