TRANSPARENCYp srncrrrcnrron forming part of Letters Patent No. 73 6,751, dated August 18, 1903..

I Application filed November 21, 1901. Serial No. 83,196. (No model.)

To all whom, it may concern.-

Be it known that 1, .Tony LosrnLLnaa citizen of the United States, residing at W ellsburg, in the county of Brooke and .State of .V'est Vi rginia, have invented certain new and useful. Improvements in 'lransparencies, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of this invention is to so construct transparencies that the matter to be displayed may be mounted therein in a very secure and inexpensive manner.

lhe invention consists in the novel strue tural features and combination of parts here inafter fully described and claimed, and il.lus trated by the accompanying drawingsportraying the invention as applied to apaperweight, wherein- I Figure l. is a bottom plan view of. a weight constructed. in accordance with my invention. Figs. and 3 are crosssectional view-sol? 1101- low weights embodying the invention, the for- .mer being unmounted. Figs. 4: and dare simiface at 5, said groove being preferably, though not necessarily, continuous. The outerportion of this groove forms the shoulder 6.

The weight shown in Figs. 2 and 3 is hollowed. or recessed inwardly from groove 5, as shown at 7, said recess being of slightly less diameter than well 3, forming ledge 8 to re ceive picture or card 9. In the form shown in Figs. 4 and 5, wherein recess 7 is omitted, the picture or card bears against the inner wall 3' of well 3.

The securing means consists, preferably, of a bulged or dish-shaped metallic disk 10, which after being inserted in well 3 is flat toned by any suitable means and caused to expand into groove 5 and engage shoulder (3 thereof, as in Fig. 5. Blanks 11, ofcardboard,

are inserted to tightly hold picture or, cardi) against ledge orwoll bottom 3', as the case maybe, the number of said blanks varyingwith the thickness of card 9 and with the depth of well 3, the latter variation arising through the unavoidable slight difference in amounts of glass supplied, to the moldsinwhich the weights are formed.

Groove 511s preferably formed while the glass is hot and immediately following the pressing or. melding of the transparency.

. The shape or form of the groove is immaterial.

Cutting the groove in cold glass is a delicate operation, as the articles are very liable to break, owing to the great tension existing in thick bodies of glass.

iavity 7 is formed for the purpose of light- .ness, and possibly the picture or card may-be displayed to better advantage therein than where it bears against a glass surface, as in the construction of Figs. l and 5. Movable devices 12 of circular or other form may he confined in cavity -7, which in a paper-weight add novelty and attractiveness thereto.

While I have shown and described the invention as applied to a paper-weight, it will be understood that this ismerely an illustration of one of the uses to which the same may be put, astransparencies of various kinds and shapes and for a variety of purposes may be constructed in accordance therewith. It will be understood that the surface 9 exposed through the transparency may bear a photograph, picture, or printed matter for advertisement or other purposes.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A transparency comprising a body of glass formed with cavity '7 terminating at its lower edge in ledge 8 and beneath said ledge the inner wall of the glass body formed with groove 5,an eiipansible metallic closure ad apted to be expanded and permanently secured in groove 5, layers of paper interposed between ledge 8 and the closure, and movable devices within space 7 .1

-2. A transparency consisting of a body of transparent glass formedwith abottom depression having a continuous or unbroken side groove, anenhibit within the depression visible through the transparent body, an exhibitconfining device closing the depression with 5, and a filling interposed between ledge S and no the closure, substantially as described.

its entire edgea'rea within and confined by said side groove/ a filling between the exhibit and the closure, substentiailiy as def sei-ibed.

3. A transparendy formed. with a bottom esvisy formed with ledge 8 and beneath said ledge formed with side groove 5, an expansiv f Tole closure'adapte'd to be, secured in groove "Witnesses:
