` i MuToscoPE.

Be it known that we, HARRY H. ELDREDGE and CHARLES J.. DOTY, citizens ofthe United States, residing at Guthrie,"in the county of Loganvand Territory of Oklahoma, have invented aznew and useful Mutoscope, of which the following is a s eciiication.

This invention re ates to stereosco es, and is primarily designed to avoid the in ividuall handling ofthe several pictures and to equipl y the device with improved mechanical means for successivel bringing aseries of pictures into position fbr viewing the same through the eyeglasses of the s'tereoscope. In this connection it is proposed to arrange the pic- Itulehandling mechanism forvmoving the pictures in rapid succession so as to give the eii'ect of a moving picture and also t0 enable the holding of each picture for any suitable period of time in front of the eyeglasses to permit careful scrutiny of the several pictures. i

Withthese and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described;l 'shown in the accompanying drawings, and articu-v larly pointed out in the appended c aims, it being understood that changes in the form, proportion, size, and minor details ma be ma e within the scope of the claims wit out departing from the spirit or sacrificing anyof the advantages ofthe invention.'

In the drawings, Figure 1 is a perspective view of a stereosco e equipped with the picture-handling mecllianism of the present 'invention. Fi 2 is a front elevation of the picture han ling mechanism with parts roken away to show the manner of rotatably supporting the picture-containing case. 3 is a detail cross-sectional view of the picture-containing case. v

Like characters of reference designate corresponding -parts in all of the figures of the rawin s.

To il ustrate the application and operation of the present v`invention, there has been shown in the accompanying drawings the eyeglass-frame or lens-frame 1 of a conventional form of stereoscope, said lens-frame 'being carried in an elevated position at the front end of an arm 2 and there bein a andle 3 depending from the front of t earm.

These parts are common and well known, and thereforev may be varied considerably without affecting the spirit of the present invention.

In carrying out the present invention there is mounted upon the arm 2 a mutoscope or mechanism for handling a series of This mutoscope includes a yokeshaped bracket 4, disposed transversely across the top of the arm 2 and carrying at its middle a depending loop 5,' slidably embracing the arm 2 and equipped with a set- .screw 6, piercin the bottom of the loop for engagement wit ythe underside of the arm to rigidly securethe bracket to the arm at any adjusted position thereon'. The arms of the yoke-shaped bracket extend upwardly, and a cylindrical case 7 is mounted between said arms loosely upon a rotatable shaft 8, which pierces the ends of the case and has its terminals formed into cylindrical journals'Q and l10, rotatable in bearing-openings 11,

To prevent rotation ofthe case, there is a pin or projection 12, carried by the inner side of one of the arms of the bracket and adapted to be snapped into a socket or opening 13 in the adjacent end -of the case.

The series of picture-leaves 14are boundy ""adiallyupona tubular core 15, having a noncircular ybore for engagement with thesimilarly-shaped non-circular-middle portion of the rotatable shaft, thereb to interlock the Lseries of picture-sheets an the shaft for simultaneous movement. The series of pictures is introduced as .a Whole through the opening 16, formed in the upper front uarter of the case, after lwhich the case is p aced within 'the bracket, and then the. shaft is thrust through one of the bearing-openin s 11 of the bracket, then through the sha f A formed in the arms or sides ofthe bracket.

The" journal-terminal 10 ofv the E roo is corrugated longitudinally, so asto form a series of longitudinal ribs 18, over which the free ends of the picture-leaves wipe, thereby to maintain the leaves yindividually separated in order that they may pass one at a timel across the .opening l6 rather than to move thereacross 1n bunches.

In 'practice the device being assembled as hereinbefore described, the lens-frame or eye.l

another slight movement 'to bring the nextV picture into view. When it is desired to produce the eec't of moving pictures, the crankhandle is rapidlyrotated, so as to swing the pictures in rapid succession across the opening of the case 7, which produces the desired effect in the Well-known manner.

Attention is directed to the fact that the top edge 1'9 of the opening 16 is deflected inwardly, soas to somewhat constrict the opening 16, thereby to eifectually hold each picture in an upright position until it snaps i arms ofthe bracket and the ends of the case past the confining iiange or lip 19, which has the eHect of accelerating therotary movement of each picture as it passes across the view-opening of the case.

Having thus described the invention,what is claimed is,-

1. A mutoscope comprising a non-rotatable case having a view-opening, a yokeshaped bracket .straddling the case, there being a pin-and-socket engagement between the case and one arm .of the bracket to prevent rotation ofthe case, a tubular rotatable core within the case, a series of radially-disposed picturesV carried by the core, an endwise-movable rotatable shaft piercing the and passing throughthe core, there being an If it is desired to carefully scrutimounted to rotate within the case with their scopes comprising a yoke-shaped bracket proing the non-circular portion of the shaft, a

succession, the'top 'edge of the view-opening interlocking connection between the shaft 5o and the core, and means' to rotate the shaft.

2. AInutoscope comprising a cylindrical case having a view-opening and provided with an internal series of longitudlnal ribs, and a lseries of radially-disposed ictures mounted to rotate Within the case with their free ends Working across the ribbed 4interior of the' case.

3. Afmutoscope comprising a cylindrical case having its inner surface ribbed longitudinally in close succession, there being a view-opening in one side-of the case,` the top edge o the opening being bowed inwardly, and a series of radially-disposed pictures Jree edges working over the ribbed interior of the case and the inturned upper edge ofthe view-opening. 4. A mutoscope attachment for stereo- 7 0 vided upon its under side with a loop having a set-screw, an endwise-removable rotatable shaft piercing the arms of the bracket and having an intermediate non-circular portion, a non-rotatable cylindricall case pierced by the shaft and having a socket and projection engagement with one of the arms of the bracket to prevent rotation ofthe case, a tubular core having a non-circular bore receiv- 8e series of radially-disposed pictures carried by the' core. the case being provided with-a longitudinal view-opening and having its interior provided with longitudinal ribs in close A 8s being inclined inwardly, the free edges of the pictures working over the ribbed interior of the case and the inturned edge of the viewopening, and means associated with one end o the shaft for rotating the same. I n testimony that we c laim the foregoing as our own we have hereto aflixed our signatures in the presence of two witnesses.
