In this manner, dampening of theinterior of tbe-,cabinet .or its lcontents ror any supporting surface is prevented. Algrojup of small,receptacles-.is partitioned ina secondary orf inner cabinet,- .G, in which the individual chambers- 17, 18,19; and i20 are arranged in steppecrelationshipg` rising upward from front toback as shown.v This arrangementgmakes the? locating of any 1desred :article an d" i ts withdrawal and freplace.-

ment easy. Neither light nor eye-glasses are needed to take out or put back the contents of this stepped group of receptacles as their separate positions are sufficiently defined to make a selection by touch a reliable manner of locating any one of the articles disposed therein. Y

The entire unitary group G, of containers is movable and may be taken from the cabinet and replaced as desired. The rear wall 26 of` the inner receptacle G is concaved away from rear wall A. The space thus provided accommodates the handle of a dental mirror 27, as shown. H is a. small, shallow pan or vessel having a stepped bottom portion 22, as indicated in Figs. 4 and 7. This vessel is placed in the cabinet and rests on the bottom thereof, the lower portion of the vessel bottom being in contact with the cabinet bottom while the upper-part of the vessel bottom, or the step made therein, rests on a. raised portion J of the cabinet bottom. This part J extends across the front of the cabinet from wall B to wall C. It is formed by placing a strip of heavy metal such as lead, across the bottom of the cabinet and folding an extension of the cabinet bottom over it or fastening it in any convenient manner. This strip is both a counterweight and a locking means for the inner removable parts of the cabinet, by inner edge 23.

From the form shown, it is evident that the cabinet, especially when empty of the various objects for which it is intended, has no tendency to resist being overturned rearwardly or toward one of the sides, B or C. By placing the bottom weight J at the front of the bottom of the cabinet a gravity component is provided which resists overturning in any direction. At one side of the container H the group G abuts against and is retained by this metal strip J.

As shown, the inner edge of this weight 23 is higher than the bottom of the cabinet, Vand this edge, 23, provides a means of locking in the receptacle group G and the vessel H. First, group G is placed in position by push* ing to the rear of the cabinet and then downwardly, so that it becomes held in four directions, viz, by the bottom of the cabinet, by the adjacent wall C, the rear wall A and the ledge 23 of weight J, respectively. Thefreceptacle group therefore has only two directions of motion left, viz, 'toward the right wall B or upward. By placing stepped vessel H between the right-hand wall of the re ceptacle group and the right-hand wall B of the cabinet, the entirety is locked in place in the cabinet against motion in any direction except upwards against gravity. Even if the cabinet were turned upside down, the friction of the adjacent parts, pressed together, would hold them against dropping out.

The vessel H is for reception of a dentifrice tube, 24'. The stepped bottom causes the tube to fall backward toward the rear wall, so that merely placing the tube bottom in t-he vessel H and raising the tube to vertical will result in the tube dropping back to the rear as indicated in Fig. 5. The different receptacles in the inner group before described, are adapted to receive any preferred articles or substances, but, in general, dental floss; false teeth; chewing gum; tooth picks and the like, in groups, individual pieces or packages of the same or differing heights.- Any of the compartments 17, 18, 19, Q0, may have any preferred form, circular, rectangular, elliptical or other. Compartment 20 for tooth-picks is preferably provided with an inwardly-projecting rim around the top opening to direct the picks towards the center, as indicated in Fig. 6.

The brushes may be mounted on either side of the door; inside, as shown in Figs. 1 to 5 or outside as indicated in Fig. 8. The specific construction disclosed in our prior application before herein referred to, is maintained in this form of the invention, viz, the provision of one wall of the tooth-brush handle receptacle higher than the opposite wall. As shown in the figures, the handle-holding member F, fixed to the face of the door D is higher than the edge of the door. This construction aids placing the brushes in their receptacles when vision fails, either because of insufficient light or defective eyesight, the latter condition, accompanied by forgetfulness of the necessity for eye-glasses in a bath-room, being common. In placing the tooth-brush in its proper handle opening, it is only necessary to lift the lower end of the handle over the lower edge of wall D and let it strike against the upper edge of memberF. This 1 locates the end of the brush handle so that it can then be dropped into the receptacle provided for it.

The inward sloping of the front wall, or door, makes the whole cabinet more compact and adds to its appearance as compared with a vertical walledstructure.

- As mentioned, the cabinet may be held in several ways, a further one being by means of a bent metal angle L whereof one end fastens, or screws, into the wall of the room or of some. article of furniture. A mating member K adapted to fit over the upwardly projecting end of L, is fastened to the rear wall A, as shown. The suspension means whereby `the hole is passed over a convenient projecting object and the weighted ability to stand on any level surface, have been memtioned.

Having described our invention in connection with illustrative embodiments. forms, proportions and arrangement of parts, it will be understood that many variants thereof are possible to those skilled in the art, and our invention, in its broader aspects, is

not limited to the specific construction herein described and shown, as changes .in the sizes, proportions, configurations, arrangements, assemblage, materials, juxtaposition and mechanical relations, as well as addi-` tions, omissions, substitutions, combinations and alterations of forms, parts, members and features, may be made without departing from the broad spirit of this invention.

` Having thus disclosed our invention, We claim and desire to secure by Letters Patent:

1. A dental cabinet having a door, an upward and inward sloping wall, a holding means for tooth-brushes attached to said door and a drip pan under the brush handles.

2. A dental cabinet having a rectangular cross section, which diminishes in area as the top is approached, a door for vsaid cabinet forming one wall thereof, brush-holding means attached to said door and a weighted bottom.

In testimony whereof, Wev have signed our names to this specification at Los Angeles, Calif., this 2nd day of July, 1930.
