COMPOSITE LANTERN-SLIDE.

Specification of Letters Patent.

Application filed July 7,1913. Serial No. 777,747.

Patented'Sept. 22, 1914.

To'all whom it may concern:

Be it known that I, SYDNEY B. AUSTIN, citizen of the United States, residing at Baltimore, Maryland, have invented certain new and useful Improvements in Composite Lantern-Slides, of which the following is a specification.

'My inventionrelates to lantern slides of the composite type, in which a picture carrying member and a screen member are .as-

sociated with each other and have relative movement so asto expose the picture sections at the open spaces between the lines of the screen, and it concerns particularly the means whereby'the picture and screen members are held together and are permitted to have the relative movement mentioned.

The invention consists in the features and combination and arrangement of parts here inafter described and out in the claims.-

I'n the accompanying drawings, Figure 1 represents a front view of my invention; Fig. 2a. rear View; Fig. 3 a. top view; Fig. 4 an end view, and Fig. 5 a sectional view along the line 55 of Fig. 1. Figs. 6 and 7 are opposite side views of a-modification;

Fig. 6 is a detail of Fig. 6; Figs. 8 and 9:

are horizontal sections, and Fig. 10 a vertical section.

In carrying out my invention I provide a two-part casing or holder, making up an open frame, or in other words, a frame open at its center to expose at this point the transparent members of the composite slide so as to permit the light to shine through for displaying the picture. While this holder may assume various forms, in the particular construction which I have chosen to illustrate my invention, it consists of a main frame member 1, in the form of a frame open at its center and having upper and lower strips or bars 2 and end bars 3. At the c'orncrs of this frame portionsare cut out and the edges at these out out points are turned laterally at 4. to provide lugs to engage the end or vertical edges of one of the members of the compositeslide, this member being indicated at These lugs 4 are four in number and engagethe vertical edges of the member 5 at or near the top and bottom thereof. The member .5 is thus held at an intermediate point with relation to the length of the main member 1, and the ends;

. allel therewith,

ways in which particularly pointed myself to mammalof this main member which extend beyond these points are extended laterally and then longitudinally of the main member and pair as indicated at 6, thus fo'rm-. of the'main member guidethe other member of the holder may be reciprocated, these guideways being indicated at 7. The supplemental or movable member of the holder is indicated at 8, this consisting of top and bottom longitudinally extending strips or bars. 9 connected by the vertical bars or strips 10, the said vertical bars at their upper and lower portions having lugs or flanges turned laterally as at 11, to engage the ends of said edges of the movable member of the composite slide indicated at 12. The upper and member have flanges or lugs extending laterally therefrom overand under respectively the upper and lower edges of the member -12 of the composite slide, these flanges orlugs being indicated at 13, and by this construction it will be seen that the member 12 'is held against displacement either vertically or horizontally in relation to the supplemental or movable holding member 8. The main member 1 of the frame or holder also has a horizontal flange 13 at its lower edge, and by this the member 5 of the composite slide is held against vertical displacement, and the flanges 13 on the supplemental member 8 by reaching over the upper edge of the slide member 12 also serve to prevent vertical displacement of this slide-member in relation to the other transparentslide member 5. The two members 1 and 8 of the holder or frame are held against displacement vertically by fingers or clips 14 of the main holding member 1 reaching up over and down on the rear side of the movable frame member 8. By will be clear that the two transparent members 5 and 12 of the composite slide are held accurately in relation to each other in one direction so that there will be no'displacement in this direction, namely, vertically, while at the same time these transparent ing at the ends members will be permitted relative move- 3 ment in a horizontal direction.

It will 'be' understood that the-use of the terms horizontal and vertical is for convenience of description, as F do not limit incitement of one The slide members are held accurately and;

getting the motion-picture eifect. In order to move-one of the framemembers relatively to the other various means may be employed.

In the particular construction shown, hoW-' ever, this means includes lugs or projections '16 extending up from the supplemental frame member and having screws 17 adjustably mounted therein to be borne upon or engaged with any suitable operating mechanism on the display apparatus in which the holder with its composite slide is placed and operated. The slide may be placed at the display point by hand or it may be brought to the display point automatically, and when at said display a-ting means will be such as to give the members of the composite slide the desired relative movement. I prefer to make the holder of sheet metal bent up as shownand de-' scribed above, though I do not limit myself in this respect. It will be observed that the.

two transparent members of the composite slide are not connected with each other ex-- cept through the intermediary of the mem-- bers of the holder or frame.

In operation one frame member with its transparent slide member moves in relation to the other frame member which is attached to the second transparent slide member.

positively in proper relation and are guided accurately in their movements. The holding lugs or flanges of the frame can be bent back to take out one composite slide and place another in position. No special formation of the transparent or glass slide members is necessary in order to render them capable of moving one on the other, nor is it neces-' sary to directly attach to them lugs or other operating devices.

Vhile I have referred to the device above described as a lantern slide it will be understood that I make such reference as being one aspect of my invention. I do not wish to indicate that its use is limited to a lantern or similar apparatus. Where I refer to a composite picture it will be understood that this term is descriptive of anycom site device to be displayed by bringing if; ferent portions thereof to view through the screen.

The screen and picture member may be connected by flexible pieces at the end to insure their proper alinement while allowing one to move in one direction or the other. These flexible pieces may be omitted.

In Figs. 6 to 10 I show a modification in point in either case the oper-.

which, like in the form first described, two

metal frames'are employed, one slidable on the other, and each carrying one of the glass members of the composite picture slide. The outer frame 1 has portion 6 overlapping the inner frame 8. The glass 5' is held to the outer frame by lugs 4 which are struck out from the frame and bent across the edge of the glass member 5. Projections 11' on the inner frame member 8 extend over the end edges of the glass member 12. The glasses and frames are held against vertical displacement by the flanges l3 and lugs 14. The hollow projections 16 are formed by bending the metal clips over upon themselves and securing the lapped gether by striking out a tongue on one which passes through an opening on the other, or a rivet may be used as at 18.

I claim l. A display device comprising two transparent members, one a screen member and the other a composite picture carrying member, and a holder consisting of two centrally open frames, each holding one of the transparent members, said frames having relative movement in one direction and held against movement in other directions to present the different parts of the picture member to the clear spaces of the screen.
