Application June .1, 1939, Serial No. 276,879

6: Claims.

This inventionrelates to projectionmachines and vhas special reference to the winding .of a photographic film in such a machine.

More particularly the invention relates toan improvement ,onmyprior application No. 212,343, filed June 7, 1938, fora machine of this class.

The most important object of the present invention is to provide agenerally improved-form of such a machine. e

With the above and other objects .in;view the invention consists ingeneral of certain novel details of construction and. combinationsfof parts hereinafter fully described, illustratedin the accompanying drawings, and specificallyset forth in the claims.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and: v

Figure 1 is a front elevation of the improved winding device with theface of the cover, removed.

Figure 2 is a detail View showing (the construction illustrated in Figure 1 of the moving parts from the rear thereof.

Figure 3 is adetail section ,partlyinelevation and partly in section on the line 3.3 of Figure 1.

Figure 4 is a fragmentary detail on an enlarged scale showing the manner in which thesupporting rollers of the filmare carried.

Figure 5 is a detail view showing, in section, the manner of connectingthe clip of the carrier ring. V g

Figure 6 is a further detail view of such ring to a greatly enlargedscale showing the manner of holding the same in position in the mainpart of the device. v t

In the device asherein disclosed there is ,provided a casing it which may or may.not,-a s may be desired, have a coverhinge thereon, said cover being of glass or having a glass panel. Secured in this casing by screws H is a bracket l2 having ajournal opening at the center thereof. This bracket l2, supports a shaft I4 as best shown in Figure 3. ;On the outer endof this shaftthere is provided a plate l5 havinga hub 3 which is keyed or otherwise secured to the shaft Hi so that the shaft and hub rotate together. This plate I5 is provided with aseriesof arcuate slots ll. Also fixed to the bracket 12 is a plate I 1 carrying a series of radial channel members I 8 wherein are slideably held the. heads lliofshafts 20 each of which ,carriesa rotary film supporting roller 25 having flanges .22 at its ends. The bracket 12 has a series of radial arms each of,

which is provided with an opening 23 wherethrough, extends the stem 24 of a yoke member 25 carrying a roller 26 having flanged ends. 21. There are at least three of these rollers as can be seen from Figure 1 and these rollerssupport a ring 28 having a gear 29 on the outer, face thereof. This gear 29 is engaged by a .pinion 3,0 which may be turned by any suitable means, so that when, the pinion is rotated the ,gear will rotate. The shafts of the rollers 2| pass through the slots l1 and also carryjthe heads [9. Now

it is to be noted'that the plate I1 is fixed while theplate l5 rotates. This plate rotates withthe hub so that when this rotation takes place the arcuate slot 1? acts as cams to move the rollers 2| in and out.

The casing lil is provided with an inlet where the film enters'and adjacent this inlet is a guide roller (H which leads the film to a second guide roller 32 and from there to a guide roller 33 carrie'd by the fixed plate I'! and having its stem passing through a slot v3 so. that rotation of the plate I5 is permitted without interfering with the guide roller 33. .Similarlythere is a second guide roller 35 carried by the plate l1 and having a stem extending through a slot 36. .Itwill be seenfrom Figure 1 that the film enters-and passes over the guide roller 3i, over the roller 32, around the roller.33, then to theroller 3.5 and thence to one of the rollers 3|. 1

Fixed on thehub It isa grooved segment 37 atone end of which is securedvthe oneend of a spring 38 which has its other end secured to a bracket-39 fixed on the member 12. The object of thisspring is to constantly urge the rotation of the member 28 in the directionof the-arrow on Figure 2. Also there is fixed ,on the hub 16a ratchet wheel 40 normally engaged by a pawl ,M

which may be released from the ratchet ,at will. In order to release the pawl ll from the ratchet there is provided a plunger 42 which extends through a bracket 43 connected to the upper part of the member l2 and on the upper end of this bracket 43 is apush button 44 which is held inelevated position by a spring 45. The arrangement here is such that when the push button is pushed downwardly then the pawl 4| is released from the ratchet 4B and the spring 38 is ,allowed to act on the segment 3! so as to turn the member l5 in the direction of the arrow shown in Figure 2.

. vBetween the rollersZl and the member. 28 there is normally interposed a split ring 46 hinged as at 41 to open and close and provided with a snap lock indicated in general at 48. This snap lock consists of a bevelled end 49 on oneside of the lock and a spring 50 fixed to the other side to engage with its notched or bevelled end 5| on the latch 49. Also there is provided a releasing member 52 which, by pushing in the direction of the member 49 will release the latch 5|.

Furthermore at suitable places around the device the ring 28 and the split ring 46 are provided with latching means indicated in general at 53, these latching means consisting of a spring latch 54 which normally engages a shoulder 55 formed in a groove 56 in the member 28, the spring latch 53 being provided with a button or head 51 whereby the shoulder portion 54 may be released from the shoulder 55.

Now under these circumstances when the film leads into the device it passes around within side of the member 46 and, by reason of the arcuate slots l'l forces the member l5 to revolve since the rollers are forced directly inward in a radial direction on account of the slots I8. Therefore the member l5 may, as one may say, wind up and cause the spring 38 to expand by reason of the fact that the segment 31 rotates in the opposite direction of that shown in Figure 2. Thus the ratchet 40 rotates and is held in its rotated position by the pawl 4| until it is desired to release the apparatus. After this the buttons 51 may be drawn to position to release the inner ring 46 whereupon the inner ring with the film may be removed from the remainder of the device.

The initial movement is to thread ribbon in by hand until it is gripped between one of the rollers 22 and the ring 46. Then by slightly rotating ring 46 the ribbon is fed to be gripped by several of said rollers and the continuation of rotation of the ring 46 winds the ribbon against the inner side of this ring without any attachment thereto. The spring38 rotates the shaft l4 when the pawl 4| is released from the ratchet 40. Now, the purpose of this is to urge the rollers 22 outwardly against the ring 45. The ring rotates continuously during winding, the plate only rotates part way.

Ther has thus been provided a eificient device of the kind described and for the purpose specified.

It is obvious that minor changes may be made in the form and construction of the invention without departing therefrom.
