FILM-FEELING mGHANISM.

Application filed January To all whom it may concern: 7

Be it known that I ALVAH C. RoEBUoK, a; citizen of the United States of America, and a resident of Chicago, in the county of-Cook andStateof Illinois, have invented certain new and useful Im rovement's in Film-Reelspecification. I ,7

This invention relates to the film reeling and rewinding mechanisms ofv kinetoscopes, and has for its object to provide a sim 1e and effective construction of parts where y therewinding of the film after its passage veniently effected, an withoutthe removal of the magazines from. the machine, all as will hereinafter more fully appear.

In the accompanying drawings :Figure 1, is a side elevation of a kinetoscopewith the film magazines in place, the position of the magazines fordel very of the film tofthe. kinetoscope being shown in full lines, and in the rewinding'position in dotted lines. Fig.

Fig. 4, is an enlarged detail sectional elevationof the connection between the han-' dle and main shaft. Fig. 5, is a detail longitudinal sectional elevation Y on line wm Fi fifisa detail longitudinal section of the lire tra, of the film magazine.

verse pin 5 en'ga" 'ng in recesses formed in the I inner end of sai hub. The hub is held from independent longitudinarmovement on said shaft b a radial screwfi passing through said'huli groove near the outer end of the said shaft. Such construction is illustrated in Figs. 2, 3

and engaging :in. a circumferential and 4, and affords a very substantial and readily detachable connection between said handle and shaft. 4 fits a similarly formed sleeve 'on the main housing 1, and in addition to forming a The tubular handle hub bearing'for the handle end of the'shaft, is

capable of the limited 'endwise adjustment above referred to, and to such end is formed with a pair of circumferential grooves 7 and 8i into' one ortheothe'r of which the set screw 9,-

passingradially through said housing sleeve, engages to x in oneor t a other of their endwiise adjustments, see Figs. 2 and '3.

10', is a bevelg'ear, and 11a spur gear positively hold said hub and shaft l mounted loosely on a common axis with the main shaft 2, and in adjacent relation to each other; such gears have "hubs which abut posed rrecesses in their abutting ends as shown.

member of the driving gearing by inactive condition, while the other mechan isms above-referred-to are in an active con' dition, and vice versa, and admits .of the armbeing used; to operate the film rewinding mechanism in addltion to itsor'dinary functions of operating the difiierent kinetoscope mechanisms, and without interference with or disturbance of said mechan-' I isms and adds mater'ially to the merit and convenience of the apparatus. Another advantage of the present construction lies in, the fact that the crank handle for both the exhibition and rewinding of the film, is on a line with the elbow of the Operator, the most comfortable position, instead of having the rewinding crank on a ,line with the shoulders or thereabout, as is usual with the ordinary type of rewinding mechanism with the crank I mounted on the reel arm.

screws 17' described. At its 13 is a shaft journaled in a side extension of the main housing 1, and-carrying at its lower end a bevel pinion14 meshing with and receiving motion from the aforesaid bevel gear 10. At its upper end the shaft 13 carries a'socket hub or coupling head 15 adaptedfor engagement with the countersh'aft ofthe rewinding mechanism hereinafter described. 16 is a reel arm or support preferably of a tubular form shown, and detachably secured to the top of the housing'extension aforesaid by means of a spider base and attaching assing therethrough and screwing into said. ousing extension as illustrated in Figs. 2 and 5. At itsupper end said reel arm is formed with an expanded or hollow head' or enlargement 18 for containing and supporting the reel shaft and gearing connections hereinafter described.

. 19 is the countershaft of the "rewinding mechanism above referred to, journaled in the reel arm 16 and having at its lower end a non-circular portion'ada ted for operative engagement with the soc et hub 15 before u per end said countershaft carries a bevel gear 20 in mesh with and adapted to impart rotation 'to .a bevel gear 21 secured to the reel shaft.

22 is the reel shaft journaled horizontally in the head 18 of thereel arm and carrying nea(1r its journal end the bevel gear 21 aforesai 23 is a circular rim arranged at one side of v the hollow head 18 and integral therewith;

such rim is formed with a'beveled eriphery as shown, and adapted to form .a utments for the holdin screws hereinafter described;

24, are the film magazines of the ordinary cylindrical or drum form shown and having at qne end a hinged door or lid 25, and atthe other end a carrying spider 26 fixedly attached to the rigid head of each magazine as shown. v

27 is a film outlet formed in the eriphery of each film magazine and preferalifly of the fire trap construction shown in Figs.' 3, 5

. arranged clamping screws 29 pass and and 6.

the rim 23 aforesaid to attach t 28 are a series ofcircularly arranged ln s on the spider 26, and through which obli ue y have 'eriphery of 1e magazine in lace in a substantial yet readily. detachab e manner.

abutment against the beveled l 30 are stop lugs or pins arranged in spaced relation on the beveled periphery of the rim 23, and adapted to permit of a limited turning adjustment of ,a magazine so that each film outlet 27 may be brought into proper adjustment with the ki'netoscope mechanisms as indicated in full lines in Fig. 1, or into a position in direct alinement with each other, as indicated indotted lines in Fig. 1, when it is desired to rewind the film from the lower or receiving magazine, back upon the reel of the u per or delivery-magazine.

31 is the film reel of any ordinary construction, and secured in a removable manner on the reel shaft 22 by a clamping nut 32 as shown in Fig. 2.
