DRIVING MECHANISM.

Specification of Letters Patent.

Patented Dec. *7, 1915.

Application filed October 29, 1914. Serial No. 869,336.

To all whom it may concern:

Be it known that we, JOHN J. Hnssn and LUCIAN STANEK, citizens of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Driving Mechanism, of which the following is a specification.

This invention relates to apparatus for feeding motion picture films and has for its object to provide a Simple, positive and accurate means adapted to rapidly advance the film consisting of a series of pictures and intermittently present successive pictures in said series to the projecting instrumentalities connected with the apparatus.

The object of the invention is further to provide means for maintaining the pictures on said film stationary in front of said projecting instrumentalities and for a predetermined period.

Another object of the invention is to provide means for adjusting said locking means whereby any looseness or play, due to the wearing of the several parts of the device, may be removed.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims.

Referring to the drawings: Figure 1 is a vertical section, partly in elevation, taken through a device embodying our invention, certain unimportant details of said device being broken awayto save space in the drawings. Fig. 2 is a side elevation of the device illustrated in Fig. 1 looking toward the right in said figure. Fig. 3 is a section taken on the line 3-3 of Fig. 1.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 5 represents a frame upon which are supported the several elements of the device embodying our invention. Upon the frame 5 is a shaft 6 journaled to rotate in bearings 77, said shaft having secured thereon a sprocket 8 constructed to engage the perforations in the film and advance the pictures constituting said film into the range of the projected rays of light. The shaft 6 constitutes the driven member of a pair of shafts mounted in said frame 5. A shaft 9 is preferably arranged below the shaft 6 and preferably one of the pair of shafts and the driving shaft of said pair, said driving shaft receivlng a continuous rotary motion from any desired source not shown in the drawings.

An intermittent rotary motion is imparted to the shaft 6 from the shaft 9 by means preferably consisting of a disk 10 having a hub 11 arranged to receive one end of the shaft 6. A series of laterally disposed projections or pins 12 are arranged upon one face of the disk 10. A bifurcated member or actuator 13 is secured to the end of the shaft 9 adjacent the disk 10, said actuator 13 having a projection or tooth 1 1 at one side thereof within the end of which is a notch or recess 15 suitable to receive one of the pins 12. As the shaft 9 is rotated the actuator 13 is also rotated, by reason of its being secured thereto, and causes the side of said projection 14 to engage one of the pins 12 and the recess 15 to receive the next pin in the series to that engaged by the side of said projection, thus advancing the disk the distance equal to that of two pins and as there are preferably 8 pins the disk 10 will be rotated one-quarter of a turn, which distance is sufficient to advance one film to the projecting instrumentalities of the apparatus. It will be evident that but a small portion of each rotation of the shaft 9, or at least the actuator 13 secured to said shaft, will be required to operate the disk 10 and as said projection 14: escapes from the last pin engaged thereby, said disk 10, so far as the actuator 13 is concerned, will be free to rotate. 1

It is essential in this particular type of apparatus that the driven member be prevented from rotating between the successive intermittent rotary movements thereof, and.

locking means have been provided for accomplishing this result which preferably consists of a rotary member or ball 16 arranged in a suitable recess 17 formed in a detachable portion 25 of the frame 5, preferably beneath the driven member or shaft 6. Said ball is permitted to move substantially along a plane extending from the axis of the shaft 6 to the axis of the shaft 9. A groove 18 is formed about the periphery of the shaft or driven member 6, preferably in the outer surface of the hub 11 within I which groove said ball is adapted to rotate.

A plurality of recesses 19 are arranged parallel therewith and constitutes the other about said, driven member along the groo 3.1-1

. ator.

' the portion 25 of said frame.

18, said recesses being capable of receiving a portion of the ball 16 to an extent sufliing a rotatable engagement with the driving member 9, preferably through the instrumentalities of a collar 22 which constitutes the hub for the actuator 13. A groove 23 is also provided in the periphery of the eollar 22 and in this groove the ball 20 has its contact with said collar; The groove 23 has a depressed portion 24 extending circumferentially thereof and constituting a cam, a distance sufiicient to permit the ball 20 to be depressed during the time the actuatoi- 13 is engaging the pins 12, preferably one-quarter of a rotation of said actu- As the ball 20 is moved radially relatively to the axis of the shaft 9, the ball 16 being operatively' connected therewith would likewise be moved radially relatively to the member 6 and the depression 24 in the groove 23 is timed'so that said radial movement of the ball 16 will take place when the recesses 19 are alining with the recess 17. Means are also provided for adjusting the balls 16 and 20 toward and away from each other, thus to eliminate any loose ness or play produced by the wearing away of the balls and their cooperating members. To accomplish this result a Wedge-shaped separator 26 is interposed between the balls 16 and 17 and arranged to be moved substantially at right angles to the plane passing through the axes of the members 6 and 9, said member 26 being pivotally secured at 27 to a slide 28 arranged to reciprocate in The pivot 27 of said member permits said separator to move with the balls when the same are actuated to lock the member 6 against rotation. To adjust the slide 28 a nut 29 is 1'0- tatablyarranged in a portion of the frame 5 and has screw-threaded engagement with a threaded stem 30, forming a part of the slide 28, and by the rotation of the nut 29, said slide will be rotated to force the separator 26 between the balls or withdraw the same therefrom.

The general operation of the apparatus hereinbefore specifically described is as follows: A continuous rotary motion is parted to the shaft '9, which motion is transmitted "intermittently through the actuator 13 and disk 10 to the driven member or shaft 6. upon which the film sprocket '8 is fast, thus moving the film to successively present the pictures thereon to the projecting apparatus. As the shaft 9 is rotated the elevated and depressed portions of the groove 23 are alternately presented to the ball 20, thus causing said ball to be moved radially relatively to the shaft 9, likewise causing the ball 16, through the separator 26, to be i moved radially relatively to the shaft 6 and at the proper time to enter and be withdrawn from the recesses 19 and thereby alternately lock and unlock said member at the proper times in its operation.

By means of a sensitive adjusting means for the Separator 26 it will be obvious that all excessive movements of the balls or driven or driving members relatively to each other may be quickly and easily removed and the coiiperating parts always maintained at the highest point of efliciency, while at the same time the driven and driving members will. be retained in their proper alinement by means of the balls 16 and 20 and their cooperating grooves, which prevent the slightest longitudinal movement of either of said members relatively to the other.
