FEED MEANS Eon. FILM-Disks.

Application led September 22, 1916.

To all whom t may concern:

Beit known that I, FREDERICK E. Kennin,

a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new Y Film-Disks; and

and useful Feed Means for i I do" hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled' -in the art to which it appertams to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to movingpicture machines both of the projecting and taking type, and particularly to machinesof this character employing films of disk form. The primary object provision inV a machine of the character described of improved meansfor imparting intermittent feeding'movements to the lm to successively move the picture panels in register with the projecting or receiving whereby to enhance the practicability and commercial value of such machines. Further objects and advantages of the invent-ion will be apparent from the following detailedy description thereof.

While the invention, in its broader aspect, is capable of embodiment in numerous illustrated in the accompanying drawings, in which- Figure 1 is a plan view of a machine enibodying my invention, with the inclosing case in horizontal section. Fig. 2 is a section thereof on the line 2 in Fig. 1. Fig. 3 is an enlarged perspective view of the film feeding mechanism embodying my invention. Fig. v4 is an enlarged sectionon the line 4-4 in Fig. 3and Fig. 5 is an elevation of the film engaging end portion of the feed lever with a part broken away.

Referring to the drawings, 1 designates the case of the machine, in the bottom of which are mounted a. pair of spaced parallel rails 2, 2 forming a horizontal track on which the wheels 3 of the carriage 4 are mounted for movement to permit a free horizontal reciprocation of the carriage relative to the case. A shaft 5 is journaled in the carriage 4 transversely thereof' and has' one end projecting from the carriage and provided with opposed clamping members Specication of Letters Patent.

ments with the carriage 4.

of my invention is thel film-disk 7 Serial No. 121,576.

6 between which a film disk 7 may bermovably clamped to have turning movements with the shaft and transversel move- The picture panels of the film-disk 6 are successively arranged in spiral order on the fact of the disk, as illustrated in Fig. 2, and as well understood in the art. It is therefore evident that when the disk is rotated to either move the pictures thereon in successive order past the projecting opening, when the machine is being used for display purposes, or to bring position for receivin ing pictures, the dis an image, when takcan be moved transversely von its axis at proper speed to allow for the proper arrangement of vthe picture panels. In other words, the transverse movement of the film must be such as to permit the picture projecting or receiving opening to move radially of the film as it follows the spiral course of the pictures.

In one end of the case 1 is mounted a shaft which carries the operating crank 8 without the case. A train of gears 9 connects the crankshaft with a shaft 10, which is mounted lengthwise of the'case in advance of the path of transverse movements of the and has one end journaled in a bearing arm 11 projecting from the adjacent case side, and with its other end journaled in a suitable bearing in one end of the case.

The shaft 10 carries a bevel-gear 12 at its inner end in mesh with a largervbevelgear 13, which is carried by a shaft'14, that is journaled in the upper endof a bearing standard 15 in the horizontal plane of the shaft 10 and at right fangles thereto, the gear 13 being disposed at the end of the shaft 14, which is adjacent to the film-disk 7 The Astandard 15 fixedly rises from the bottom' of the case 1 and has its upper end forked, with the shaft 14 extending across the forked opening and journaled in both furcations Patented Jan. 22,1918.

successive panels into in a bearing head 17 havand lever 26 and acts to normally urge an naled in the bearing head 17 lengthwise of its carrying arm and in position to stand in axial register with the shaft 10 when the bearing arm has been swuno into suitable position therefon The shaft 19 carrles a bevel-gear 20 0n its inner end in mesh with the bevel-gear 13 and of the same size as the gear 12, thus causing like rotation to be communicated to the shaft 19 from the shaft 10 through the medium of the gears 12, 13 and 20. A cam-wheel 21 is mounted on the outer end of the shaft 19 and has a protuberant portion 22 on its periphery for the purpose hereinafter described. The shaft 19 has an eccentric portion 23 within the opening 18- in the bearing head 17, and this eccentric portion turns within a yoke 24, that is carried at the inner end of a stub-shaft 25, which projects horizontally toward the Elmdisk 7 through a registering bearing in a side wall of the bearing head 17, 'as best shown in Figs. 3 and 4.

A film feeding lever 26 is mounted on thel outer end portion of the stub-shaft 25 for rocking movements relative thereto and has its film engaging arm projecting horizontally to a point between the gear 13 and the film-disk 7 and provided at its outer end with a transversely projecting finger' 27,

the outer end of which is socketed to receive a film engaging member 28 of rubber or other suitable material for frictionally engaging the film side and imparting feeding movements thereto as the feed arm is successively rocked, as hereinafter described. A coiled compression spring 29 encircles the stu -shaft 25 between the bearing head 17 outward movement of the lever 26 toward the lm 7. At each revolution of the shaft 19, the eccentric 23 causes the shaft 25 and lever 26 to be drawn inward to film releasing position and then permits an outward film engaging movement of the lever under the influence of the spring 29. rlhe tail-end 26a of the lever 26 terminates over the camwheel 21 and carries a roller 30 in position to be engaged by the protuberant part 22 of the cam-wheel at each revolution thereof. A coiled contractile spring 31 connects the tail-piece of the lever to the head 17 and normally retains the lever with its rear end or tail-piece 26a lowered in stop contact with an adjusting screw 32, which threads up through the outer end portion of the 'bearing head 17 and is adjustable to vary the normal position of the lever with .respect .to the cam-wheel 21. At each revolution of the cam-wheel, the peripheralv projection 22 thereon engages the lever roller 36 and imparts a film feeding movement to the lever 26 against the tension of the spring 31. The engagement of the cam projection 22 with the lever roller 30 is-so timed with respect to the reciprocatory movements of the lever i intense v carrying shaft 25 that the working end of is at the limit of its outward movement with respect to the bearing head 17, or in other words, when the lm wiping member 28 of the lever is in engagement with the thus causing a normal feeding movement to be imparted to the film-disk by the downward wiping action of the feed member 28 thereagainst. Y

A segmental rack-bar 33 is pivoted at its upper end to a side of the bearing head 17 at its outer end, as by a screw 34, and projects downward and inward ,through the lower portion of the standard 15 and has its rack-teeth, which'are provided on the upper surface thereof, in mesh with a pinion 35, which pinion is mounted on a shaft 36, that is journaled in the standard 15 and has one end projecting outward therefrom through a side of the case 1 and carrying a hand-wheel 37 at its outer end. 1t is evident that a turning of the shaft 36 and pinion 35 will impart longitudinal movement in one direction or the other to the rack-bar 33 and a corresponding raising or lowering of the bearing head 17 with -respect to the said axis, so that the feed lever, when swungv downward in film feeding direction, will have a movement which is concentric to the film axis and which, in addition to imparting a' turning movement to the film, also draws the film and its'feeding carriage 4 slightly to the right to compensate for the spiral arrangement of the picture panels.

It is evident that the speed of transverse movement of the film-disk depends on the inclination of the lever 26 with respect to the plane of transverse movement of the film axis and that an adjustment ofthe bearing arm 16and parts carried thereby is effected for this purpose by a turning of the shaft 36 and pinion 35.

The film-disk 7 is pressed or held firm in opposition to the point of engagement of the same by the feed lever26 by a pressure pad 38, which is carried at the free end of an arm,39, that projects from a shaft 40, which shaft is suitably journaled in vertical position within the adjacent end portion of the case. A coiled contractile spring 41 connects a tail-piece 42 on the arm 39 to an adjacent portion of the case l andacts on said arm to retainthe pad 38 inyielding contact with the rear side of the film. The film pressing movement of the pad 38 is limited, however, by a stop-pin 43, which is jection positioned to have stop contact with the tail-piece 42, as shown in Fig. 1. The'picture image is transmitted to the ilm or projected from the same through an opening 44 in the pad 38, said opening being properly positioned and of suitable size for the picture panels in the film to successively move into register therewith as the film is rotated. When the 'film-disk 7 is at rest, it is firmly held to the pad 38 by a pressurefoot 45, which is carried at the outer end of one arm of a bell-crank lever 46 and has an opening 47 therein in register with the opening 44 in said pad. The lever 46 is fulcrumed to a bearing arm 48 projecting from the adjacent case end and has one arm projecting at the outer side of a cam-disk '49 on the shaft 10 in position to be `engaged and rocked by a cam projection 50 on the adjacent cam face at each revolution of said shaft. coiled contractile spring 51 connects the le-.f'er 46 to a stationary plate or member within the case and acts to normally move the lever 46 to retain its pressure-foot 45 in Contact with the lm and its other arm in the path of movement of the cam projection 50. As the cam pro- 50 strikes the lever 46, the lever is rocked to release lthe engagement of the pressure-foot 45 with the film and this releasing movement is timed to. take place immediately prior to the film feeding movement of the feed lever 26, the pressure-foot being held outward from the film during such feeding movement.

In the present instance, the large bevelgear 13, in addition to serving as a driving connection between the gears 12 and 20, is utilized as the shutter member of the ma-` chine and for such purpose is provided with -two openings 53 in its web portion at opposite sides of its center, which openings 'are successively brought into register with the openings 44 and 47 in the pad 38 and pressure-foot 45, respectively. The gear 13 is of suitable size with respect to the gears 12- and 20 to turn once for every two revolutions of said other gears so that one of the openings 53 is brought into register with the projecting openings of the machine during each half revolution of the shutter gear.

The member 52 above referred to, in the present instance, constitutes a light protector plate which is disposed between the shutter gear 13 and the film and is provided with an opening therethrough in register with the line of transmission of the picture ima es.

gIn the use of my improved machine, a film-disk 7 is first clamped to the shafty 5 -and the carriage moved to the left in posipanel 1n the outer to move mto regprojecting openings tion for the last picture convolution of the seri ister with the picture when the film is rotated in lfeeding direction. Upon a turning of the operating crank 8, a rapid vrotation is communicated to the shaft 19 from the shaft 10 through` the medium of the gears 12, 13and 20, there- 70 by causlng the eccentric`23 in conjunction with the spring 29 to impart both an inward and outward movement to the feed lever 26 with respect to the film-disk 7 at each revolution of the shaft 19 and also to 75 cause the cam-wheel projection 22 to act on the outer end of the feed lever 26 to impart a quick downward rocking'or film feeding movement to the opposite end thereof agamst the tension of the spring 31, which 8o feedmg movement takes place during the period that the lever is held upward` by the eccentric 23 with its wipermember 28 in contact with the lm. It isv therefore evident that the lever 26 has compound move- 85 ments imparted thereto at each revolution 0f the shaft 19, which movements coperate to move the lever into lm engaging position, to then impart a feedingv or turning movement to the film whereby a succeeding 9`0 picture panel thereon is moved into projecting position, and then to retract the lever from film engaging position. The setting of the rocking axis of the lever 26 below the horizontal plane in which the lm ye5 axis and the lever wiper member-28, when elevated, are disposed, causes the downward wiping or feeding action of the member 28 on the lm to impart not only a rotary feeding movement to the film but to draw it slightly forward or to the right to allow for the gradual inward working of the film panels toward the center of the film due to the spiral arrangement of such panels. It

is evident that as the convolutions of the picture panels become shorter or of less diameter, the forward feeding of the film must be correspondingly increased 'and this, in the present instance, is accomplished by the operator slightly turning the control shaft 37 at frequent intervals so as to increase the incline of the feed finger. At each down ward rocking or feeding movement of the lever 26, the pressure-foot lever 45 is swung outward from engagement with the film by Vthe coaction of the cam projection 50 withV the lever 46. In order to facilitate an insertion of a film-disk 7 between the pressurepad 38 and lpressure-foot 45, the shaft 40, which carries the pressure-'pad arm 39, is 120 projected without the case 1 and carries a hand-control wheel 54, thus enabling the operator to turn said shaft and swing the pressure-pad 38 outward away from the film against the tension of the spring 41 when 125 desired.
