materials, it has been found in actual practise that considerable clearance has to be allowed be"- tween the cover and the body so as to compensate for manufacturing tolerances and the factor of expansion and contraction that results in this material or the tacky effect that might result from the finishes used upon the box. 'To overcome such conditions that may result from the above factors and still provide for a frictional fit suflicient to hold the cover in closed position, the improvements in my invention resides particularly in the use of suitable frictional elements carried in the beaded end of the cover opposite from its hinging end, which elements are allowed to project beyond the transverse edges of the cover a sufficient distance to have firm frictional engagement with the adjacent walls of the body member. More specifically the friction elements are made from compact cylindrical felt wads forced into restricted sockets drilled into the transverse ends of the cover bead.
The full nature of this invention along with other objects and various advantages thereof will be more apparent from a consideration of the following description when read in connection with the accompanying drawing in which Fig. 1 represents a perspective view of the vanity box construction showing the cover in an opened position.
Fig. 2 is a plan view of the vanity box with the cover in a closed position, and
Fig. 3 is an enlarged sectional view drawn along the line 3-3 of Fig. 2 showing in detail the frictional means.
Referring now to the drawing in which the reference numerals designate like parts throughout the several views, numeral indicatesgenerally the-body member and numeral H the cover member. tion, referred to above, the body and cover members are so designed as to be made preferably from wooden material that can be readily fabricated in long strips of molding material of gen- As pointed out in the Root applica-' eral U-shape in cross-section. In cutting the body from such a strip of molding material there will result two opposed upstanding side walls l3, whereas the other ends of the box will be open. Within the upper face of the base of the body there is provided a relatively large recess l4 into which powder may be disposed in accordance with the Root teaching.
The cover member H likewise is adapted to be transversely cut from long strips of molding material: having two parallelling beaded edges I5 andlG which become the ends of the cover member parallel to the longitudinal axis thereof. To'
form a compartment within the box when the cover is closed, the cover member is assembled in an'inverted position, i. e with the beads l5 and IS in a dependent position, to the bod member II) with its axis normal to the longitudinal axis of the body member and in between the body side walls l3. One of .the beaded edges I5 of the cover member which for convenience's sake will be called the hinging bead is pivotally enaged to the ends of the body side walls I3 through the medium of wooden pivot pins I1 driven into suitable recesses formed in from opposite ends thereof and have rotatable engagement in complemental alined bearing openings [8 in the body side walls l3.
As pointed out in the objects of the invention, 7
in order to preclude the cover from sticking or binding in between the side walls of the body when in closed position, a considerable amount of tolerances is allowed between the cover edges and side walls l3, therefore making it necessary to provide for means to hold the cover in closed v which is forcibly assembled a cylindrical felt wad 20 of relatively firm consistency and of a length to project beyond thecut or transverse edges of the cover a distance sufficient to have a relatively firm frictional engagement with the adjacent surface of the bodyside walls I 3 in a manner such as shown-in Fig. 3. The felt wads are cut transversely from long cylindrical firmly compressed felt strips which thus provide for innumerable fibre ends that resiliently bear against the adjacent fiat surface of the body flanges which preferably are left in a smooth finished state. The frictional effect produced by this construction is suflicient to maintain the cover in closed position yet free enough to allow the op erator to open the cover without having to exert an extreme amount of force in hinging the cover relative to the body.
To facilitate the opening of the cover there is provided an arcuate cut-out or thumb opening 2| in the front edge of the body that allows ample room for the operator to wedge his thumb underneath the front beaded edge ii of the cover member and permit a sufficient thumb purchase a cover member having an end hingedly connected to said flanges and entirely confined between said fianges when in a closed position, the opposite end of said cover member having sockets provided in each of its transverse edges, and compact cylindrical felt wads of a normal diameter slightly greater than said socket and disposed in said sockets under force of pressure to completely fill said sockets with one end of said wads firmly seated against the base of their respective sockets as a stop and the opposite end projecting beyond their respective cover edges a distance to have frictional engagement with the adjacent smooth wall surface of said flanges. the degree of frictional effect between the wad ends and the adjacent flange wall surfaces being uniform for both the closingand opening operations of said cover member when moving within the area i of said flanges.
