Another object of this invention is to provide wall or partition units of the character stated and which are the floor selectively. A further object of this invention is to provide a mobile: wall unit of A specific object of the present invention is to provide a mobile wall or partition unit of the character stated and in which the structure is improved and simplified in many casters.
Other specific objects ofthis invention obvious and in part pointed out hereinafter. In accordance with the invention disclosed in this and.
rooms and arrangements movable wall or partition will be in partvarious numbers and sizes of of rooms. In order to makev this economically feasible, the invention consists of a, section so constructed that the I with adjustable bases and tops, as well as with adjustable slip moulds whereby the units can be re-arranged to place the wall or partition where it is desired to be without marring or mutilating the walls, ceilingsor floors or even having an attachment thereto. At the same time the units are so constructed that when they have been moved to the desired place they can be expanded vertically so that they will have firm and steady contact with the floor and also with the ceiling and the slip moulds can be adjusted to cover any space that might be present between two adjacent units. Preferably the mobile wall units are in the form of cabinets having such depth and width as desired for ample storage space.
The invention accordingly consists in the features of construction, combinations of elements and arrangements of parts which will be more fully described hereinafter and the scope of the application of which will be pointed out in the claims that follow.
In order that a clearer understanding of this invention may be had, attention is hereby directed to the accompanying drawings forming a part of this application and illustrating certain possible embodiments of this invention and in which:

Similar reference characters refer to similar parts throughout the several views of the drawings.
Referring to the drawings the expansible mobile wall unit includes a cabinet section having a back panel 40, side panels 41 and 42, a stationary top frame 43 having cross bracing 44 and corner backing 4'5 and carrying a top panel 46. This cabinet section also has a bottom panel 47 above which a sill 48 extends across the front of the cabinet section and supports a panel 49 providing a space for a drawer 50 between the sill 48 and panel 49 and the bottom panel 47 of the section. At the front of the cabinet on each side are door jamb rails 51 for sliding doors 52 which may be of the show case type and are slidably supported by and between the upper panel 46 and the sill 48.
To the derside of bottom panel 47 of the cabinet moved about and section are fixed two spaced reinforcing strips 53 which are provided with casters 54. Also beneath the cabinet section is a frame 55 constituting a base or rest for the cabinet section. This cabinet base or rest 55 is connected to the cabinet section by means of jack bolts 56 which extend through the bottom panel 47 of the cabinet and have nuts 57 pinned thereto beneath the panel 47 preventing the bolts from being raised upwardly through the panel 47. Below the nuts 57 the bolts extend through threaded apertures in screw plates 58 which are mortised into and fastened to the cabinet rest or base 55 which is provided with recesses 59 into which the lower ends of the bolts 56 extend. As shown in Figs. 4 and 7 the bolts 56 may have their heads 60 exposed above the panel 47 and adjacent thereto so as to be accessible for the turning of the bolts in the screw plates 58 to raise and lower the cabinet section and the cabinet rest 55 relatively to each other. However, if desired, and as shown in Fig. 8, longer jack bolts 56' may be provided and have their heads 60 exposed above the cabinet section panel the bolts being locatedbetween the sides of the drawer 50 andthe side panels of the cabinet section. The shorter jack bolts 56 become accessible for manipulation when the drawer 50 is removed. The longer jack bolts 56' become accessible for manipulation upon opening the doors 52.
Not only are means provided for raising and lowering the cabinet section relatively to the floor but means are also provided for expanding the cabinet vertically at its top to insure firm contact with the ceiling. Also adjustable slip moulds are provided on the front "and back of the cabinet on both sides and which can be projected horizontally to cover any space that may be present between two wall units placed side by side or between a unit-and-an adjacent wall. Preferably the slip moulds are also adjustable vertically and are so connected with an adjustable upper frame of the cabinet section that by adjusting the slip moulds vertically the adjustable upper frame of the cabinet may be moved upwardly into firm contact with the ceiling or lowered to be out of contact with the ceiling when it is desired to move the unit to another location.
As shown the adjustable upper part of the cabinet includes an adjustable frame consisting of front and rear pieces 62 and'side pieces 63 and which surrounds and slidably overlaps the stationary frame 43. This frame is supported by the upper ends of four slip moulds 64, two .on the front of the cabinet and two on the rear at the side edges there'of. The upper ends of the slip moulds have a mortise 65 cut in the back and the ends of the adjustable frame members 62 are shaped to fit into these mortises so that the adjustable frame may be raised and lowered by raising or lowering the slip moulds while allowing the slip moulds to be moved sidewise in and out relatively to the adjustable frame and cabinet in all vertically adjusted positions of the slip moulds and the adjustable frame carried thereby.
Concealed means are provided for holding the slip moulds 64 to the cabinet for both horizontal and vertical adjustment thereon. These concealed means for adjustably anchoring the slip moulds to the front of the cabinet are shown best in Figs. 10 and 11. As will be seen a vertical slot 66 has been cut through each jamb rail 51 and oppositeto this slot 66 a horizontal slot 67 is cut into'the back of but not through the slip mould 64 and eye bolt 68- is inserted through the vertical slot 66 in the cabinet jamb with-the eye 69 of the bolt 68 projecting into the recess 67 'of the slip mould and retained therein by means of a retaining pin 70. At the other end of the bolt there is a washer 71 and wing nut 72, which, when tightened, holds the slip mould 64 securely against thejamb 51. At the rear of the'cabinet where normally there are no jamb rails, and slots corresponding to: the vertical slots 66iformed'in' the jamb rails 51 may be formed-directly inthe-rear panel 40of the cabinet and of 1 course shorter eye bolts provided with wing nuts may be hold and at the same time subject to change-by the occu-, used. However, if desired, the cabinet may be provided pant of the house into an entirely different arrangement with rear corner posts (not shown) and the vertical slots of the house without expense incident in moving a wall for the eye bolts provided in these posts. or closet section inherent in present day construction.
