FILM WIN DIN G AND REWINDING APPARATUS.

Application filed February 28, 1919.

To all whom it may concern:

Be it known that I, JOHN C. RAMsHER, a citizen of the United States, residing at, Shenandoah, in the county of Schuylkill and State of Pennsylvania, have invented new and useful Improvements in Film \Vinding and Rewinding Apparatus, of which the following is a specification.

My present invention has for its general object to provide film-winding and rewinding mechanism in a unitary apparatus in which the parts are so constructed and relatively arranged that a number of reels may be used in succession and while one film is being run to display the pictures thereon in a kinetoscope, the preceding film, the pictures of which have been exhibited, Will be rewound.

In the present embodiment of my invention I have elected to illustrate an apparatus for handling five films in succession together with the reels complementary to the films and the appurtenances of the reels; and the novelty, utility and practical advantage of the invention will be fully understood from the following description and claims when the same are read in connection with the drawings accompanying and forming part of this specification, in which:

Figure 1 is a side elevation of the unitary apparatus constituting the best practical embodiment of my invention of which I am cognizant.

Fig. 2 is a transverse section taken in the plane indicated by the line 22 of Fig.

Fig. 3 is an enlarged section taken diametrically through one of the reels.

Fig. 4 is a section taken in the plane indicated by the line 44 of Fig- 3, looking in the direction indicated by arrow and showing the means complementary to each reel for preventing casual turning thereof.

Fig. 5 is a detail enlarged perspective showing the fastener of each reel for attaching one end of a film thereto.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

I prefer to have my novel apparatus comprise a plurality of, say six, plates 1, each of which is of the configuration shown in Fig. 2. The said plates 1 are arranged in spaced relation, Fig. 1. and are held apart by sleeves 2 and nuts 3. and are also. through the said agency, connected together so as to Specification of Letters Patent.

Patented Aug. 19, 1919. Serial No. 279,701.

be capable of movement toward the left on rods 1 and also toward the right in Fig. 1 as a unit.

Extending loosely through the plates 1 and at right angles thereto are shafts 4 and 5, each of which is provided at an intermediate point of its length with a portion 6 of angular form in cross-section. The said shafts 4 and 5 are designed to be continuously rotated through any suitable driving connection from the means usually employed for actuating a kinetoscope or moving picture machine. There are five reels 7 on the shaft 4, and five reels 8 on the shaft 5, and each reel is provided with a central bore 9 of a shape and size to receive the angular portion 6 of its respective shaft, and is also provided with a central lateral projection 10 at the left, Fig. 1, through which the said bore extends. Each reel is also provided at its left-hand side with a spring-pressed detent 11 that is adapted to be engaged with an arcuate rack 12 on the opposed plate 1, Fig. 4. This provision manifestly permits of each reel being secured against casual rotation until it is desired to put the same into use, whereupon the operator manually disengages the detent 11 from the rack 12 and then slides the body 13 to which the detent is hinged at 14 in- Wardly in'the housing loops 15, until said pivot belt 14 is inwardly beyond the outer housing loop, when the detent will be retained out of engagement with the rack 12. To detachably secure each reel against rotation, the operation described is reversed. In its hub 16 each reel is provided with a concavity 17, and hinged to the hub is a hollow fastener 18 in which is a finger'piece 19 and which fastener is normally and yieldingly retained in working position by a spring 20.

At 21 are idler rollers, and at 22 are films passed over said rollers 21 and fastened at their ends to the reels in the manner described, and designed to be wound off the upper reels and on the lower reels and vice versa. as hereinafter explicitly set forth.

Suitably supported at 23 is a manipulating lever 24, having a detent 25, Fig. 1, and interposed between the said lever 24 and the adjacent end plate 1 is a link 26. Y Supported in proper proximitv to the detent 25 and the remainder of the apparatus is an arcuate rack 27 having at intervals seats 28 to receive the detent. The said seats being preferably numbered in regular sequence as illustrated.

In the practical use of my novel apparatus it will be manifest that by advancing the apparatus step by step toward the left in Fig. 1, the first reels toward the left will be turned by reason of the lower reel toward the left being engaged b the angularportion 6 of the lower sha 5. Before such engagement is efiected it is the province of the operator to release the upper and lower reels toward the left by manipulation of the detents 11 complementary thereto, and when the engagement'described takes place the film com lementary to the reels mentioned will ObVlOllSl be wound upon the lower reel toward t e left and off the upper reel toward the left. At the completion of the run of the said film for the exhibition of the pictures thereon the apparatus is moved as a unit toward the left so as to put the second lower reel from the left in engagement with the angular portion 6 of the lower shaft 5, and this engagement is also effected after the upper and lower second reels from the left have been manually released for rotation. In consequence of the said manipulation the second film from the left will be let off the upper reel from the left and taken up on the lower reel from the left, and at the same time, by reason of the upper reel toward the left having been engaged with the angular portion 6 of the upper shaft 4, the first film toward the left will be rewound on the upper reel toward the left. This operation is continued in step by step manner until all of the films have been manipulated in the manner described.

It will be gathered from the foregoing that it is within the purview of my invention for the apparatus shown in Fig. l to be handled and ship ed as a unit, in which event provision Wlll be made for the ready connection of the rod 1 to a kinetoscope, and the similar connection of the shafts 4 and 5 to the means employed for the actuation of the kinetoscope, or the said rods 1 may be supported and the shafts 4 and 5 may be rotated in any other approved manner.

Having described my invention, what I claim and desire to secure by Letters-Patent, is:

1. The combination of a shaft having a driving portion, a plurality of reels loose and movable laterally on the shaft and successively into engagement with said driving portion to be rotated thereby, and means through which the reels are so moved.

2. The combination of shafts arranged in and parallel relation and each having a driving portion of one, shaft being in advance of the driving portion of the other, a plurality of reels loose and movable laterally on each of the shafts and successively into enga ement with the driving portion thereof to e successively rotated thereby, and means through which the reels are so moved.

3. The combination of a shaft having an angular portion, a plurality of reels loose and movable laterally on the shaft and each having an angular bore to receive said angular portion when the reels are moved successively into engagement therewith, and means through which the reels are so moved.

4. The combination of shafts arranged in spaced and parallel relation and each having an angular portion; the angular portion of one shaft being in advance of that of the other, sets of reels loose and movable laterally on each shaft and each having an angular bore to successively engage the angular portion of its respective shaft, and means through which the reels are so moved.

5. The combination spaced and parallel relation and each having an angular portion; the angular portion of one shaft being in advance of that of the other, sets of reels loose and movable laterally on each shaft and each having an angular bore to successively engage the angular portion of its respective shaft, means for laterally moving the reels, means for effecting connection of films to the reels, means for holding the reels against casual rotation, said means being detachable, a handle connected with the means for moving the reels, and means for adjustably fixing said handle.

6. The combination of shafts arranged in spaced and parallel relation and each having a driving portion; the driving portion of one shaft being in advance of that of the other, a plurality of reels loose and movable laterally on each shaft and successively into engagement with the driving portion thereof to be rotated by said driving portion, means through which all of the reels are moved laterally as a unit, and manual means connected with said moving means.

7 The combination of spaced plates, a shaft extending therethrough, a reel loose on the shaft, 21 rack on one of the plates, and a detent on the reel and constructed and arranged to be yieldingly pressed into engagement with the rackand also constructed and arranged to be detachably secured out of engagement with the rack.

In testimony whereof I afiix my signature.
