Specification of Letters Patent.

Patented Jan. 5, idllfio application filed. January 16, 1914. Serial No. 812,415.

To all whom it may concern Be it known that ll, CARR D. Gounon, a citizen of the United States, and a resident of Boone, in the county of Boone and State of Iowa, have made certain new and useful Improvements in Moving-Picture Apparatus, of which the following is a specification.

My present invention relates to improvements in moving picture apparatus, and particularly to that class of moving picture apparatus in which the film is fed downwardly on to and partiallyaround an upper continuously driven feed roller, and in which an idle presser roll is disposed adjacent to this'feed roll for the purpose of putting the film thereon, it being well known that the film is provided with series of apertures along its opposite edges and the feed roll has circular series of spurs or projections adjacent its. opposite ends which co-v operate with these film apertures, and it being further well known that the presser roll is mounted upon a bracket fulcrumed on the frame of the machine in such manner as to permit of the movement of the presser roll away from the feed roll when it is desired to thread a film through the machine.

The above arrangement in practical use has given rise to a serious and considerable disadvantage, namely in danger of adherence of a portion of the film to the feed roll and its passage almost completely around said roll,'the usual loop formed between the upper continuously driven feed roll and the lower intermittently driven' roll enabling this action to take place, causing frequent breakage of the film and interruption in n order to obviate this difliculty and disadvantage it is the object of *my present in-' ventionto supplement the parts mentioned with a taking ofi roll and to insure the desired release of the film from the feed roll and to thus act in a manner substanwhich is in efiect a putting on roll.

It is a further object of my invention to" mount the taking off roll upon a member which will form the fulcrum of thebracket upon which the presser roll or putting on roll is carried." V

In the accompanying drawings which illustrate my invention, Figure 1 is a perspective view illustrating certain parts of a moving picture apparatus in order that the relative positionsof the frame and the parts immediately effected by my invention may broken away and in section, Fig. 3 is a verti" cal section taken through the parts shown in 1* 1g. 2 substantially on line 3-3 of said figure, and, l 1g. 4 1s a detail perspective View of the supporting bracket and putting on roll and, illustrating the taking ofi roll and its parts in detached relation.

up Referring now to these figures and partlcularly to Figs. 1 and 2, in the type of apparatus to which my invention is applied,

the film strip indicated at A is fed downwardly around an idler a disposed forwardly on the upper continuously driven feed roll B and is extended rearwardly over the upper portion of this feed roll and pressed into contact With the said feed roll in order to efl'ectively engage the spurs b of the latter with the. side apertures of the StI'lP, by means of a presser roll G mounted upon a'bracket D, which bracket is acted upon by a spring E and is fulcrumed upon the frame of the machine so that it may be moved away from the feed roll and against the tension of spring E to the position shown in dotted lines in Fig. 2 when it is desired to thread a film strip through the operating parts. v

llt will be seen that the presser roll C is as usual provided with enlarged circumferentially grooved end portions 0 and that, by virtue of spring E, the presser roll is firmly though elastically held against the film strip and operates to put the said strip on the feed r0 11 B. Due to this arrangement it has been found that the film strip, which is intended to pass over only a small portion ofthe surface of 'the feed roll, will frequently adhere thereto and pass around therewith, as indicated in'dotted lines in Fig. 2, causing an, acute angular bend in the film strip where it is intended that the same shall extendlrearwardly and downwardly in a vfull loop, as shown in full lines in said figure? In order to defeat this I provide a taking ofi roll F, the particular structure of this roll itself being identical with that of the roll G, and in order that such a roll may be conveniently associated with the bracket D -now in use, 1' preferably mount this roll F upon an arbor F having an outer slotted head I and an inner threaded end 7"" llO adapted to pass througha split spring bushing cl disposed-within the pivoted opening of the bracket, it being intended that this threaded inner end of the screw arbor shall extend through the pivoted opening of the bracket and screw into a threaded openingthe film strip when the next intermittent movement of the lower .7 feed roll causes a jerk upon the strip.

I claim:

1. In moving picture apparatus, the combination of a feed roll. partially around which the film strip is carried, a presser roll engaging the film at a point adjacent to the feed roll for putting the said film on to the said roll, a bracket which carries thesaid presser roll having an opening therethrough, a screw extending through the bracket opening for pivotally securing the bracket upon a portion of the frame of the apparatus, and having an elongated shank and a head at its outer end, and a roll journaled upon the shank of said 'screw adja- Y separate the film from the feed roll.

2. In moving picture apparatus, the combination of a ,feed roll partially around which the film strip is carried, a presser roll engaging the film strip to put the same on the feed roll, a bracket which carries the said presser roll, a second roll engaging the film strip at a point beyond the presser roll to separate the same from the feed roll, and a member upon which the said second roll is journaled, extending through the bracket and forming a fulcrum upon which the latter is movable to move the presser roll to- Ward andaway from the feed roll. 3. In moving picture apparatus, the com-' bination of a feed roll partially around which the fihn strip is carried, a putting on roll arranged to press the film strip against the feed roll, a taking 01f roll arranged to separate the film strip from the feed roll after its passage beyond the putting on roll, and a bracket fillcrumed at a point adjacent to the feed roll and in.

connection with which the said putting on and taking ofi rollsare mounted.
