.Application filed September 20. 1907. Serial No. 393.772.

.To .allwhomktt may. concern:

:Be it :known-fthat .1, SHERMAN M. TANNE- A1HIIaL,-a citizen'of the-.UnitedStates of Amerea,:residing` at Connellsville,in the county of Fayette and State of Pennsylvania, have invented certain new and useful Im rovements -in`MovingPicture Apparatus, o which the following is a s ecification, reference being had therein to. t e;accompanying drawings.

This -inventon b a paliatusz an 'fits primary o ject is to avoid .it-lie unwin mfrewinding ofthe film st-rip em loyedin meehanismsof this class.

further object of the invention is to pro- -vide rollers orgpulleys lof'novel construction,

and relative arrangement, for guiding the film stri j 1n its travel.

.'lihe invention consists in the combination `with a -moving l.picture 'machina vof va film Istri 'having its endsconnectedsto forman.

end ess band; 'and in an endless film strip formed .adjacent l'to its `edges with .perforations to receive-.,thesteeth ofsprocket Wheels for driving'theendless strip. 1

The invention further consists of means for supporting the endless :lilm-stripain such a manner as to direct theifrontportionyof said strip away from the sight opening of the apparatus, so that the projection of the pictures upon the strip b opticon will not eobstructed.

The construction of the improvement will be fully described? hereinafter in connection .with the accompanying drawing which forms part of the specification, and its novel features will be defined in the appended claims.

In the drawing: Figure l 1s a view in perspective, partly broken awayof a moving 1picture machine embodying the invention,

ig. 2 is a diagrammatic view partl in side elevation and partly in elevation of t e same,

vand Fig. 3 is a detail front elevation showing the oppositely disposed conical .rollers over which the film strip passes. Y .tral longitudinal sectional view of the film box that is supported beneath the machine,

and Fig. 5 is a horizontal sectional view of said frame Y alining with the lens 5 of the s tereo ticon.

j k Below the table 1 is suspended a box8,-

` the same.

The reference numeral 1 designates a table uponwhich is supported a stereopticon 2, and a frame 3 supporting the ilm mechanism, provided with ai sight opening 4 The revoluble shaft 6 of the film eeding mechanism is provided'withja crank 7.

l'relates A,to moving picture.

-8a between the block 8c means of the usual `stere- Fig. 4 is acen-A `of the frame 3 wi formed at its rear end with top With a slot 1 0. Parallel na ed in the walls of the slot 9 orinsuitable brackets provided therefor, and parallel brackets 13 project from the opposite wallspof the slot l0 forming bearings fora airv of rollers 14. Below these rollers 1.4 Wit 'n the-.box

8 are supported two shafts y15 Jand' 15a; the

shaft`1'5`carryingaroller l 5 having sprocket wheels 16, while the shaft 1 5a carries arolleril 7 provided with grooves 17X to receive theteath of sprocket Wheels 16. Within thefbox 8 is a casing 8a, open at the front end and closediat therear end. This casing is provided lwith side flanges 8 by means `of which it isseeured to the innerfaces of the ysidewalls ofthe'hox 8. lIn the casing -8a is'a sliding'block 8v ro-g' vided with forwardly-projectin arms 8 :in

which the shaft 15a 1s .j ournaied. hOne or more coil springs 8b is mountedin the casing and the rear endof said casing for the purpose of holding-:the

roller 17 yieldingly against the roller-15 fear.-

ried by shaft 15. The film is firmlyheld'befv tween the rollers 15 and 17 byathe springer springs 8b forcing the block ,80.andzrollerlf7 towards roller 15X, thus preventingthelm from being displaced Wlth relatio'n tothe Sprocket wheels, and also allowing for any unevenness or irregularities in the film'.

Bracket arms 18 'project from the forward side of the frame 3, and in said arms is. supported a roller 19.'

The numeral 20 designates .the endless film strip formed adjacent to each of its edges with perforations" 21 to receive the teeth of the sprocket wheels 16. This 'stripy passes through openings 22 and 23 formed in the table, and through the'slots 9 and 10 of the box. by a belt (not shown) operating over pulley 24 of the moving picture-machine and over` pulley 15 carried by the shaft 15.

A bracket 25 extends rearward from the frame 3, and mounted in bearings 26 depending from said bracket is a 'conical pulley 27. Another conical pulley 28 is mounted in bracket bearings above an opening 2 9 in the frame 3, through which opening the filmstrip passes.

The two conical pulleys 27 and 28 are oppositely disposed as shown in Fig. 3 and are outv of vertical alinemenf so that that portion 30 of the film-stri which is moving in front' not obstruct the part of the film opposite the sight opening.

aslot QI-and-'atits rollers 12 are. jour-1 described.

The endless film strip is also guided by parallel rollers 31 supported on the front side of the frame 3, and any slack in the film strip will'fold upon itself within the box 8, as

' shown.

Parts of the feeding mechanism not specifically described are intended to be repre' sented only conventionally, the characteristic and novel features of the present improvement being the structure above fully for efiectingYI the forward portion of a film strip fedfrom said mechanism out of alinement with the lens of the stereopticon.

2. In a moving picture machine the combination with a stereopticon, of a frame car- 'n the film feeding mechanism, and means v for efiecting the forward ortion of a film strip fed from the fee ing mechanism through said frame, 'comprising oppositely disposed conical pulleys supported in the A frame in different vertical planes.

3. In a moving picture machine, the combination with a stereopticon, of a frame sup A ported in front thereof, a box below said frame, film-carryingand. feeding mechanism supported on said frame, land means for defiecting a portion of a film strip fed from said mechanism away from the sight opening of the machine.

4. In a moving picture mechanism, the combination with a stereopticon, of a frame i supported in front of said stereopticon, a film-carrying and feeding mechanismsupbtoJ-F ported by said frame,- said frame provided with an opening to receive a film, a conical roller in said opening over which the film is drawn as it is fed through the feeding mechanism, a bracket carried by the rear face of the frame and located on adifierent plane than .the opening in said frame, a conical roller carried by said bracket to receive said film, and a film-receiving box supported below said frame. l Y

5. In a moving picture mechanism, the combination with a stereopticon, of a frame supported in front of said stereopticon, a film-carrying and feeding mechanism sup ported by said frame, said frame provided with an opening to receive a film, a conical roller in said opening over which the filma' Y ff' Y- drawn as it is fedthrouglrthe feeding'm'echanism, a bracket 'carried by the rear face of the frame and located on a different vertical plane than the opening in said frame,'a conical roller in said bracket to receive said film, a film-receiving box supported below said frame, and means within said box for holding the film strip taut during the feeding operation.

' In testimony whereof I affix my signature in thepresence of two witnesses.
