6 Claims. (01. 41-10) My invention relates broadly to crystal novel ties or paperweights and more particularly to an improved structural arrangement for facilitating mass production of crystal novelties or paperweights. i

One of the objects of my invention is to provide a construction of crystal novelty or paperweight employing a minimum number of parts for sealing a liquid. filled container enclosing a figure with respect to a base member for facilitating mass production of crystal novelties or paperweights.

Another object of my invention is to provide a construction of crystal novelty or paperweight in which a fluid-tight seal may be obtained between a fluid filled container enclosing a figure and a base member employing a minimum number of parts.

Still another object of my invention is to provide a construction ofcrystal novelty or paperweight including a closure, device for the fluid filled figure enclosing container adapted to pro-v. vide for the expansion'and contraction of fluid within the container and effectively preventing.

the formation of air bubbles within the container.

A further object of my invention is .to provide a construction of fluid filled figure enclosing container and base support therefor wherein a displaceable diaphragm forms part of theclosure for the fiuidfilled container and allows expansion and contraction under conditions of variable temperature or barometric pressures without formation of air bubbles.

A still further object of my invention is to provide a I construction of crystal novelty or paperweight which requires minimum amounts of critical materials for its fabrication.

Other and further objects of my invention reside in the structural arrangement of closure means for a figure enclosed fluid filled container and mounting means for the supporting base structure, as set forth more fully in the specification hereinafter following by reference to the accompanying drawings, in which:

Wherever hereinafterl have referred to my invention as a crystal novelty it will be understood that I intend the term to also include and be synonymous with paperweights or ornaments embodying the structure set forth in the accom panying specification. i

' My invention is directed to an improved construction of crystal novelty which doe not require appreciable critical material for its fabrication. Metal and rubber are regarded as criti-- cal materials and inthe fabrication of certain forms of. the crystal novelty of'my invention, metal and rubber are eliminated. The crystal container is provided with a screw threaded neck portion which terminates in a projecting beading adapted to make a fluid-tight connection with a gasket member. The gasket member may be a shell-like plastic composition or any water-proof material which has expansive or contractive properties. The plastic composition material may be supported by an oiled fiber composition. material such as oiled stencil paper which serves. as a backing for the sheet-like plastic composi tion material. Thefiber sheet material is sup portedby a, base member of porcelain, wood or other material capable of being turned, moldeoL. or o-therwise'fabricated, which is screw threaded to receive the screw threaded neck of the crystal.

chamber formed therein immediately behind the fiber sheet-like member of fiber material and a breathing aperture is provided in the base allowing pressure changes due to variations in temperature and barometric conditions to occur in the breathing chamber.

In certain forms of my invention the heading may be circular, sinuous or irregular in its contour for establishing a firm seat and seal with respect to the plastic sheet-like material. Certain forms of my invention may include a cap member engaging the screw threads of the neck of the crystal to secure in place a transverse member which may be flexible in character and formed from any suitable waterproof plastic composition having expansive or contractive properties. In order to facilitate the expansion and contraction of the diaphragm-like plastic closure member, the cap which seals the member in position with respect to the end of the neck of the crystal maybe open at its center to permit displacement of the plastic diaphragm in accordance with changes in temperature and barometric conditions and prevent the enclosing of air in the fluid filled crystal and thereby preventing development of undesirable air bubbles.

In the forms of my invention which involve a closure cap for closing the neck of the crystal, I apply a water-proof cement around the annular inside portion of the base against which the capped crystal is applied. The cement unites the annular skirt of the cap with the inside annular wall of the base. In the form of my invention in which the crystal is directly screw threaded into the base I apply a varnish or any other water-proof sealing composition to the inside of the threads for insuring a firm connection between the crystal and the base. i

Referring to the drawings in detail, reference character I designates the base structure which may be formed from porcelain, wood or other material capable of beingturned, molded or otherwise fabricated. The upper end of the base is recessed at 2 and is provided with internal screw threads at 3. The'central portion of the recess 2. is depressed or cutout as represented at 4 to provide a chamber for the displacement of the closure diaphragm which extends transversely of the neck 6 of the container 1. diaphragm 5 is formed from fibrous composition material such as oiled stencil paper and is in the shape of a disc which is supported on the annular ledge 8 extending around the central depressed portion 4 of the recess 2.- The fibrous composition material disc 5 serves as a backing support for the sheet-like plastic'composition material 9 which is directly seated against the projecting beading ID, that is, carried by the annular neck portion 6 of the container 1. The annular neck portion 6.0f the container 1 is provided with diametrically opposed recesses H and I2 therein adapted to receive the correspondingly shaped lugs l4 and I5 that project from diametrically opposite sides of the circular base l5 of the .crna mental figure I! which is enclosed by the container 1. The figure or base I6 is apertured in any suitable position such as indicated at vl8 to allow circulation of the fluid l9 enclosed by the container for permitting access of the fluid directly against the sheet-like plastic composition member 9 for exerting expansive or contractive force thereagainst. The base member I6 is spaced from the interior wall of the neck 6 by a narrow annular gap indicated at which also permits direct pressure application of the fluid The closure l9 against the sheet-like plastic composition material 9. precipitate particles of insoluble material indicated at 2| for simulating whirling Show which may be induced upon shaking or agitating the container 1. g

The sheet-like plastic composition material 9 extends directly in contact with the base [6 and over the annular beading l0 and against the peripheral extremity of the annular neck 6 supported by the fibrous backing material 5. As the screwthreads 611 on the neck 6 of container 1 are engaged in screw threads 3 in base i and screwed to a firm securing position for closing the neck of the fluid filled container 1, the annular beading 10 presses into the sheet-like composition ma.- terial 9 forming a fluid-tight closure. The base 16 of the figure I! has a hollow interior portion represented at 22 providing a displacement chamber interiorly of the figure for the movement of the sheet-like plastic composition material 9 and backing sheet '5 as represented in Fig. 7 under conditions where contractive forces are exerted within the fluid filled container 1. The base I with the central depressed portion 4 therein serves as a similar or complementary chamber in which the backing sheet 5 and the sheet-like plastic composition material 9 may be displaced under conditions of development of expansive forces within container l. Base I is provided with a central passage or aperture 23 leading to the atmosphere so that atmospheric pressure is con-- tinuously exerted against the diaphragm-like backing sheet 5. It will be seen that the oppositely disposed chambers 22 and 4 provide ample space into which the diaphragm-like members 5 and 9 may move. I

Fig. 5 represents more clearly the simplified relationship of the parts constituting the crystal novelty. It will be seen that the assembly process is extremely simple as it is only necessary to deposit the backing sheet-like diaphragm 5 in the recess 2 in base i, then deposit the diaphragm 9 of the sheet-like plastic composition material,

'- next mount the figure in the crystal container by engaging the lugs l4 and H5 in recesses II and 12,

then applying varnish or any other water-proof sealing composition to .the inside of the threads 3 in base I, and finally applying the fluid filled and precipitate enclosing container 1 to the base I by engaging screw threads fiaon neck 8 into screw threads '3 in recess 2 of base I.

In lieu of the central projecting beading I0, I may provide a sinuous 0r angul-arly directed projected beading on the peripheral extremity of the neck 6 of container I as illustrated at 24 in Fig. 4. The angularly extending rib or projection enters the sheet-like plastic composition material 9 forming a fluid-tight joint for confining the fluid within the container 1 and preventing leakage of air with development of undesired air bubbles.

InLFig. 9 I have shown a modified form of my invention where a metallic closure cap member 25 and a screw threaded skirt 2-6are adapted to engage the screw threads Ba on neck 6. The screw threaded cap 25 has a central outstruck portion 21 therein adapted-to'be seated in a conformed depression 28 in the base 29. The central outstruck portion 2! provides a chamber 30 into which the expansible and contraciziblediaphragm 31 which is seated in cap 25 may be displaced under conditions of expansion and contraction forces which may develop in container I. The closure cap 25 has an annular portion 251; which The fluid l9 floatingly suspends the serves as a bearing means against lugs 14 and I5 through the material of diaphragm ill for securely maintaining the figure I! in position within container 1. The projecting beading I is forced into the material of the diaphragm. 3| forming a fluid-tight seal. The chamber 22 in the base of figure 11 allows displacement of diaphragm 31 into the chamber while chamber 30 allows displacement of the diaphragm 3| away from the fluid within the container depending upon various conditions of temperature and barometric-pressures. A port 2111 connects chamber 30 with the atmosphere through port 23.

The base 29 has a circular recess 32 in the upper portion thereof adapted to receive the screw threaded cap 25 and permit the cap to be anchored in position by application of a waterproof cement 33 as shown.

In Fig. 10 I have shown a further modified form of my invention in which a closure cap 36 has a screw threaded skirt engaging the screw threads 611 on the neck 6 of container 1 and is centrally apertured at 35 as shown. The annular peripheral portion 36 of the cap 34 serves as a mounting means for the figure I? as the annular portion 36 of cap 34 directly engages the expansible and contractible diaphragm 3! which bears directly against lugs I4 and I5 of the base I6 of the figure H. The projecting beading It enters the material of the gasket 3| forming a fluid-tight closure. The expansible and contractible diaphragm 3! may be displaced into the chamber 22 and the base of figure H or may be displaced into the chamber 31 in base 29 through aperture 35 in closure cap 34 according to variable conditions of temperature and barometric pressure. A port 38 extends through base 29 into chamber 3'! for applying atmospheric pressure directly against diaphragm 3|. The screw threaded closure cap 34 enters the recess 32 in base 29 and may b secured in position with respect thereto by means of the water-proof cement indicated at 33.

The forms of my invention illustrated herein have been found highly practical for mass production of crystal novelties inexpensively with minimum labor and with minimum critical materials. However I realize that modifications in the structural arrangement of the crystal novelty of my invention may be made and I intend no limitations upon my invention other than may be imposed by the scope of the appended claims.
