EDWARD o. SOHRIEFER, OF CINCINNATI, OHIO.

EXTENSIBLE CASE.

To all whom it mag concern:

Be it known that I, EDWARD G. SOHRIE- FER, a citizen of the United States, residing.

at Cincinnati, in the county of. Hamilton and 5 State of Ohio, have invented certain new and useful Improvements in Extensible Cases, of which the following is a specification.

It is the object of my invention to provide an extensible case com rising a case-section or sections having a bac and sides but without to or bottom, a top unit and a bottom unit, or forming a case in which a shelf or shelves may be assed up and down and secured at desirab e points for forming a compartment either within a case-section or overlapping case-sections, with a door or doors swinging in upright position, and my invention consists in providing a case-section of the character described with a door swin ing in upright positions; further, in providing means for connecting the severa doors of the several sections or units for forming a united door; further, in providing a top unit, or a bottom unit, or both, for a case of the character described, with a swinging leaf or door; further, in providing means for connecting said ,door or leaf with the united door of the case-section or sections, further, in novel means for hanging the shelves for o affording full inside clearance for the case and compartments in the case; further, in novel means for hanging the doors for affording full clearance at the front to the inside of-the case; and further, in the parts and in 5 the construction, arrangement and combinations of parts hereinafter scribed and claimed. I do not independently herein claim the adjustable shelf support herein shown and more fully dedescribed, having filed a plications on said subject-matters, being erial Nos. 105388 and" 105389 filed April 30, 1902, to which reference is respectfully made. I have also, in another application, Serial No. 92460,

shown described and claimed the case-section or unit comprising a back and sides without top or bottom, to whichapplication reference is respectfully made, and have also shown, described and claimed such case-section in connectionwith other matter. in other applications filed: by me February 3, 1902, Serial Nos. 92462 and' 92463, to which reference is also respectfully made.

2 tion, the to unit, and the bottom unit in separated re ation. Fig. 3 is a plan view of a detail, showing the shelf support, means for mounting the door, and the connecting means between sections. Fig. 4 is a detail in vertical section, takenon a line corresponding to the line 03-00 of Fig. 3, showing the shelf support and .means for holding the sides of case-sections against sidewise displacement. Fig. 5is'a detail in perspective of the connecting means between sections. Fig. 6 is. a detail in side elevation showing the connecting means between doors. Fig.

7 is a cross-section of the same in separated relation taken on the line y'y of Fig. 6; and,

Fig. 8 is a detail in cross-section taken on the line 2-2 of Fig. 6 showing the retaining means for the same.

1 represents a case-section; 2' a top unit, and 3 a bottom unit. The case-section consists of two sides 4 5, and a back 6, all preferably close, and connected by suitable means. The doors 7 8 are supported on the case section and swing in vertical position on hinges 9. The hinges are preferably located to the outside of the inner-face 10 of theside of the case-section for a distance corresponding to the thickness of the door frame between said inner'face and pivot of the bin e, so that when the door is swung open at rig t angles to the case its inner face -11 will be in substantially the vertical plane of extension of the inner face 10 of the case-section for giving the inside of the case-section full clearance at its front for removal of articles therein. For accomplishing this object conveniently, I provide the front of the sides of the sections with posts 12, having rabbets 13 for receiving the outer edge of the door.

In order to further provide clearance on the. inside of the case-section for articles, I also provide the sides with recesses 15 in which I secure vertical shelf-strips 16.

17 represents a shelf support, provided at its upper end with a hook 18 for taking into a )ertures 20 in the shelf-strips 16. The

s elves 14 or similar article support' device may be recessed, as shown at 21 for mittin the ledge 22 of the shelf sup ort. The shel strips may also be channele as shown at 23,

for strength and for receiving the shank 24 of the shelf support. Screws .25 secure the shelf-strips to the sectionqsides. One of the shelf su )ports ma be provided for each corner of the shelf fbr supportin the shelf in horizontal position at desirable eight. The.

shelf-strips and supports are preferably of metal. By means of this improved construction full clearance is given the insideof the case, and full clearance is also iven compart ments between shelves, the s elf-strips and supports being located within the lanes of extension of the shelves and vertical walls of the case-sections.

ed e having a groove 27, or vice versa, for" I have shown the upper edge ofv the casesection provided with a tongue 26, its lower 'ai ing in seating the cases upon each other,

' of the parts.

"tween the shelf-strips and the s1 es of the case, thereby'i-removing them from view when the case is set up. For readily findingf the connecting pieces when placing a unit, I.provide the grooves 31 32 with fiarin openings 33 34. One of the pieces is re erably placed at the front at each side 0 the case lapping two units placed one above another. 1 The object of the connecting pieces is to hold the sides of ,the case-sections T e channel 28 in the connecting piece is for the purpose of strength and to receive the hook 18 when inserted into openings 0 pcsite the connecting-piece. The sides o the A case-section are also provided with grooves 29 to rear of the shelf-stri s for receiving said hooks, the channels 28 eingpractically a continuation of the grooves 29.

If case-sections are placed one upon another, I prefer to connect-the doors of the several sections for forming a uniteddoor. The doors may also be provided with tongues 35 and rooves 36 similar to the case-secmeans for connectingthe doors, I have shown'wedge pieces 37 38 connected respectively to the respective doors to be connected, with a wedge-clamp 39 adapted to take about the'two wedge pieces and to be forced upon the same for firmly uniting the doors, a s ring 40 being adapted to take 7 against ri g'es 4:1 for preventing displacement of the clamp. The wedges and wedgepieces may besunk into depressions 42. Any suitable number of doors may be thus connected for forming a united door. It is y of course obvious that other means for connecting'may be employed.

If thedoors are provided with tongue and oove, as stated, it is advisableto provide a oor or leaf 51 for the top unit adapted to be 7 connected with the door of the section immeas by means similar to the agxainst sidewise displacement or bulging.-

sections. The leaf 51 maybe hinged to the top unitby a hinge 9. The bottom unit may also be provided .with a door or leaf 52 connected to the bottom unit bya hin e 9 and to the door of the section immediate y above by aconnection similar'to the connection for connecting the doors between sections. In the form shown, the lower edge of the leaf or strip 51 will be provided with a groove for receiving the tongue of the door immediately below and the upper edge of the leaf or strip 52 would be provided with a tongue for taking into the roove of the door of the section above, and t eupper edge of the leaf 51 and 'lower' edge of the leaf 52 would be square of the leaves for forming a with the sides complete finish when the case is closed. dust strip doors and leaves at one side of the case for overlapping the doors and leaves at the other side of the case.

53 may be provided for each of the The top unit may have depending sides 54' 55 and a dependin back 56 corres onding to the height of the eaves 51, and t e bottom unit may have upwardly extending sides 57 res onding to the height of the leaves 52.
