claims. (cl. fzs-18.7)

i a .sleeve shaft 23 which extends rotatably My invention relates to moving picture machines, and more particularly to the reels thereof, by means of which the film is quickly and eifectively fed from one reel to the other. It applies more especially to the lower reel into which the film is fed and from which it may be removed to the upper.

The object of the invention is to enable the operator, when the winding is completed, to remove the film from the lower reel and transfer it to the upper magazine. A further object is to produce a device that can be easily and cheaply manufactured and readily manipulated.

In the drawings forming a part of this specification, and in which like symbols of reference represent corresponding parts in the several views:

Figure 1 is a side elevation of a projection machine embodying my invention;

Figure 2 is an enlarged view, partly in elevation and partly in section, showing the lower magazine and a portion of the upper magazine.

Figure 3 is an enlarged section on the line 3-3 of Figure 1; l

Figure 4 is a section on the line 4-4 of Figure 3 to illustrate disk I5 merely, the apertures and other parts not shown, and the casing entire;

Figure 5 is an enlarged section on the line 5-5 of Figure 3, with the casing and other parts omitted, to illustrate a slotted plate I 8 used in the device; Y

Figure 6 is a .greatly enlarged fragmentary section, of a modification, on the line 6-6 of Figure 3, showing the opposite side of the plate shown in Figure 5;

Figure 7 is a fragmentary section on the line 1-1 of Figure 6, with parts broken away; and

Figure 8 is a fragmentary detail showing a modification of the device shown in Figure 3.

The projector of the device, I0, is of the usual form, and is provided with an upper magazine II, and a lower magazine I2. Each magazine has an access door, these being indicated at I3 and I4 respectively. Inthe lower magazine is mounted a fixed disk I5 having a shaft receiving opening I6. The disk I5 is provided with radially extending slots I1. Fixed on the rear face of this disk is a circular plate I8 having a shaft opening I9 and slots 20 registering with the opening I6 and slots I 1. On the rear face of this plate I8 is a series of pairs of Z-shaped confronting guides 2|, the guides -of each pair being located on opposite sides of a respective slot. EX tending from the rear wall of the magazine I2 is a stub shaft 22 whereon is revolubly mounted through the openings I6 and I9.

On the front end of the shaft 23 is xeda revoluble disk 24 having a series of arcuate slots 25 extending from the central portion of the disk to points at the periphery thereof. The slots 25 correspond in number to the slots I1. suitably mounted in the lhousing is a series of rollers 26, preferably three in number, spaced to receive va lm drum, including fa cylindrical band ('21, carrying outwardly extending flanges 28 which ride on the rollers 26. The inner flange 28 has a ratchet' 58 which rides on rollers 26.

Through each pair of registering slots I1 and 20 and through a corresponding slot 25 extends a shaft 29. Each shaft 29 carries a slide 29a which is mounted between a respective pair of guides 2l to slide therein.r It will now be noted that the curvature of the slots 25 is such that movement of the shafts 29 inwardly of the disk I5 eifects camming action on the plate 24 to,v

cause it to rotate in the direction of the arrow A of Figure 2. On each shaft 29 at thev front end thereof is mounted a flanged roller 30, the flanges being of grooved rubber which may be formed by a pair of flanged disks 3 I, asin Figures 6 and 7. Preferably there are sixteen of these rollers which are evenly spaced Within the drum 21.

Fixed to the central portion of the disk I5 is a pair of rods 32 and 33 which pass through a slot 34 formed in the disk 24 concentric thereto. There is also a third rod 35 which passes through an arcuate slot 36 formed in the disk 24 concentric thereto. The

rods

32 and 35 have heads on each of which is mounted three anti-friction rollers 31. The rod 33fcarries but two rollers 38, a guide 39 being arranged between them. The rods 32 and '33 have their outer ends within the drum 21, while the rod 35extends forwardly of the drum and is inclined asV shown in Figure 3.

The lm F is led from the upper magazine Il over a series of guide rollers 40 in the head 4I and upper part of the lower magazine I2, and passes to the rolls 31 on the rod 35, thence to the rolls 31 of the rod 32, thence between the rolls 38 and around one of the rolls 30. 'Ihe drum 21 is split into halves which are hinged together at 42, and the end of the iilm F passes between` the halves at 43 and iscaught beneath a clip 44.

A shaft 45 is suitably journalled in the lower part of the magazine I2 and is drawn by a belt 46 deriving power from the motor of the projection machine which engages a pulley on said 'held from movement by shaft. Onthe forward end of this shaft is a pinion 48 which engages a gear 49 carried by the drum 21. The lower shaft 29 is extended rearwardly as at 50 and carries a belt pulley 5I. Above the shaft 45 is a stub shaft 52 Aon which is mounted ran idler pulley 53 alined with pulley 5I. On the shaft 45 is fixed a pulley 54 alined With the pulley 53 and a belt 55 is trained around the

pulleys

53 and 54 and engages the pulley 5l. This causes the lower roller 30 to rotate as the shaft 45 is driven. Also, the rotation of the shaft 45 rotates the drum 21 and theV rotation of the drum draws the film around the rollers 30 to lie in a tight coil within the drum at the periphery thereof, this action beingassisted by the coaction between the

lower rolls

30 and 26. In the form shown in Figure 8 theV shaft 52 may be used as a driving shaft, being itself drawn by the rli'his is merely a reversal of the form shown in Figure 3, the power being imparted through belt 10, through pulleys 56 and band ll.V

When all of the film has been wound within the drum the rolls. 30 rwill have moved inwardly. These rolls are, during the start of operations, a pawl 51 engaging a l the flanges 28, a pull'rod 59 being actuated to releasethe pawlafter one or4 two convolutions of filmV have been wound within the drum. AsV the winding continues the ratchet58' on one of slots 25 are cammed by the shafts 29 causing the disk y24 to turn. When the winding has been completed, the door I4 is opened and the disk `24 manually rotated to draw the rolls 3% inwardlyv clear of the coil of film. The drum and lcoil of film may now be removed from between'rthe supporting rolls 2G.

The film may now be removed from the drum by opening the latter slightly on the'hinge 42 and the drum replaced for further winding. The coil of film may now be placed on a suitable reel ready for unwinding from its exterior in the usual manner. i f In order to restore the shafts 29 to their normaloutward positions a coil spring 23a has one end connected to thesleeve 23 and has its other end connected to a fixed post 23h.v This tends to turn the cam disk against the direction of the arrow in Figure 2 and thus urges the shafts 29 outwardly. l y Y Having now fully described my invention, what I claim as new, and desire to secure byLetters Patent, is :Y Y
