Renewed September 23, 1933 46 Claims.

This invention relates to projecting machines in general, and more especially to projecting machines in which the travel of the film is automatically reversed to effect rewinding after completing a period of projection, and in which the travel of the film is again automatically reversed after being rewound to repeat the projection period.

Machines of this character have been found particularly adapted for use as lecturers machines and salesmens machines. When these machines are used as salesmens or lecturers machines, the operator is very frequently called upon to repeat a portion of the film projected. To this end, the present invention has for an object to provide improved means whereby the travel of the film may at any time be interrupted, a portion rewound, and the film again reversed to project such rewound portion.

It has further been found that when these machines are used as lecturers machines or salesmens machines, it frequently happens that only a portion of the film may be of interest at a particular time, and that therefore it would only be desired, if at all, to project and repeat a portion of a film. As an instance, a lecturer may be confined to the first half of a film, and in the course of his lecture mayfind it desirable to repeat such first half, but is not interested in projecting the second half at such time, and in turn, at another time, he may only be interested in projecting and repeating the projection of the second half of the film. Similarly, a salesman when addressing one prospective purchaser, may find it advisable to project only one portion of the film, and here too, let us I assume that this salesman may find it advisable invention aims to provide to project only the first half of a film to one prospective purchaser at one time and the second half of the film to a second prospective purchaser at another time. It is of course understood that both the lecturer and salesman may be interested in repeating the portion of the film originally projected. To this end, the present improved means whereby the machine may be set so that only one portion of the film is projected, at the end of which the projection is interrupted automatically to effect rewinding, and again automatically to reverse the travel of the film when the be ginning of such portion of the film has been reached in the act of rewinding to repeat the projection of such particular portion, in which case the portion of the film not to be projected could be ignored entirely at such particular time.

The present invention has for a further object to provide, in machines of this general class, improved means whereby the wear of the film, due to reversing the travel thereof, is reduced to a minimum. To this end, the present invention aims specifically to provide improved means whereby a sufiicient dwell or period of interruption is caused to take place in the feeding means of the film before the reversal takes place, so that the film is afforded sufficient time to come substantially to rest before the reverse feeding action comes into play.

To further protect the film against tear and wear during the reversing action, the present invention aims to provide improved means whereby the intermittent actuator of the film is caused to be released from engagement with the film before the travel of the film has been reversed, and not again caused to engage the film until after the travel has been reversed. 5

In the interest of protecting the film against wear and tear during the reversing action, it is still a further object to release the film from the film guiding gate at the exposure location before the travel of the film has been caused to reverse, and to maintain such gate in open or released position until after the travel of the film has started to reverse.

These and other features, capabilities and advantages of the invention will appear from the subjoined detail description of one specific embodiment thereof, illustrated in the accompanying drawings, in which Figure 1 is a front side elevation of the complete machine.

In the embodiment illustrated, there is provided a main platform A, from the right hand side of which, see Fig. 1, there extends an arm 13 on which the lamp housing C is mounted. The lamp housing C has adjacent to its light aperture a funnel shaped guide D for the light rays. Extending upwardly from the main platform A, there is a main frame member E extending in a plane forwardly of the mouth D of the funnel member D, see Fig. 4. Extending rearwardly from the upper end of the frame member E to the left hand end thereof, there is a reel housing 1, and extending from the lower end of the main frame E below the reel housing 1, there is a second reel housing 2. The reel housings 1 and 2 are for convenience provided with hingedly connected

closure members

3 and 4 respectively. In the reel housing 1, there is a reel 5 mounted on the shaft 6, and in the reel housing 2, there is provided a reel 7 mounted on the shaft 8.

The reel 5, in this instance, serves as the supply reel, and the reel 7 as the take-up reel, the film F traveling from the reel 5 to the reel 7 during projection and traveling from the reel 7 to the reel 5 during the rewind action.

As the film F passes from the reel 5 to the reel 7, it will pass through the housing 9 to the intermittent actuator, the sprocket 10, cooperating with the film to register it in focusing position intermittently. In the projecting operation, of course, the reel 7 will be driven continuously at varying rates of speed as distinguished from the intermittent action of the sprocket 10. In order to compensate for this difference in action, the vibrating take-up lever 11 is provided, which has a guiding shield 12 over which the film F passes from the sprocket 10 to the reel 7. This lever 11 is yieldably mounted to exercise tension upwardly on the film F between the sprocket 10 and the reel 7. In order to prevent the formation of slack in the film F between the reel 5 and the housing 9, the cooperating tension levers 13 and 14 are provided. The lever 13, in the present instance, consists of a yieldable spring member having a loop 15 exercising downward tension on the film F between the lever 14 and the reel 5, while the lever 14 has a yieldable guiding shield 16 and is yieldably mounted to exercise an upward tension on the film F between the housing 9 and the looped end 15 of the lever 13. The construction and operation of these spring loaded levers are described and claimed in the copending application of Clarkson Ulysses Bundick and myself, Serial Number 44,482, filed July 18, 1925.

For driving either the shaft 8 in the projecting operation, or the shaft 6 in the rewinding operation, driving means are provided which are operatively mounted to the front of the main frame E.

In the projecting action, the lower shaft 8, Fig. 2, is driven. As shown in Fig. 6, the shaft 8 is provided with a friction disc 17 disposed adjacent to the friction disc 18, mounted on the clutch shaft 19. The shaft 19, as shown in Fig. 3, is supported in the auxiliary frame member 29 and bracket 21, the shaft 19 having a beveled gear 22 formed thereon between the frame 20 and the bracket 21, being provided with a portion 23 extending from the beveled gear 22 to the bracket 21. The shaft 19 is the driven shaft. The friction disc 18 is slidably of the collar 24, and is secured to the outercylindrical shaft 27 which is freely rotatable on the inner upwardly extending vertical shaft 28, the outer shaft 27 being pivotally mounted in the lower bracket 29, and the inner shaft 28 being pivotally mounted in the upper bracket 30. The vertical shaft 27 is operatively connected to oscillate with the vertical shaft 31, which is pivotally mounted at its lower end in the bearing bracket 29 and at its upper end in the bearing bracket 30. When it is desired to cause the friction disc 18 to engage the friction disc 17, the lever 26 is caused to rock with the shaft 27 about the shaft 28 to press the friction disc 18 into engagement with the friction disc 17.

When it is desired to rewind the film F, in which case the film travels from the reel 7 to the reel 5, the friction disc 18 is withdrawn from engagement with the friction disc 17 to liberate the shaft 8, and the shaft 6 of the reel 5 is operatively connected to be driven. For this purpose, the shaft 6 of the reel 5 has the clutch pins 32 radially extending therefrom to cooperate with the longitudinally extending pins 33 mounted in the collar 34, which is slidably mounted on the shaft 35, but fixed to rotate therewith due to the fact that the pins 33 extend through orifices formed in the disc 36 fixed on the shaft 35. The annular member 34 has pivotally connected thereto the forked member 37, which is fixed on the vertical inner shaft 28, which is rotatably mounted in the cylindrical outer shaft 27. When the cylindrical outer shaft 27 is rocked to withdraw the friction disc 18 from engagement with the friction disc 17, the inner shaft 28 is rocked to cause the pins 33 to extend into the path of movement of the pins 32, whereupon the shaft 6 will be caused to rotate with the shaft 35. The inner vertical shaft 28 is operatively connected by means of links with the vertical shaft 31, this link connection being such, relative to the link connection between the outer shaft 27 and the shaft 31, that the oscillation of the shaft 31 in one direction will cause the shafts 27 and 28 to oscillate in opposite directions to one another. Thus, the oscillation of the shaft 31 in one direc tion at one time will withdraw the friction disc 18 out of engagement with the friction disc 17, and at the same time cause the pins 33 to be moved into the path of movement of the pins 32, and at another time, when the shaft 31 is oscillated in the opposite direction, it will cause the friction disc 18 to be moved into engagement with the friction disc 17 and at the same time cause the pins 33 to be moved out of engagement with the pins 32.

At this time, it might be desirable to note that in order to prevent the overspeeding of the shaft 6 when the film travels from the reel 5 to the reel '7, a brake is provided, consisting of a brake drum 38 fixed on the shaft 6, see Fig. 3, and a yieldably mounted brake shoe 39 secured to the spring 40 fixed to the short end of the lever 14. Thus, see Figs. 1 and 2, in the act of projection, if the

levers

13 and 14 do not exercise tension on the film F and if slack is thereby formed in the film F between the reel 5 and the housing 9, the brake shoe 39 connecting the brake drum 38 will retard or arrest the rotation of the reel 5, until such slack has been taken up and the normal feeding operation resumed.

The shutter and its operative connections, which form no part of the present invention, will now be described to set forth its association with the present mechanism. To the rear of the frame member E, there is formed a shutter housing 41 in which a shutter of usual construction is 'rotatably mounted, operative connections being provided between the shaft 42 of the shutter 43 and the shaft 44 extending from the housing 45, see Fig. 5, to the bearing 46 secured to the frame member E, and having a gear 47 formed on the outer end thereof in mesh with the. gear 48 formed on the shaft 49, which is journaled in the bearings 50 and 51 secured to the frame member E. The inner or right hand end of the shaft 49 has freely mounted thereon the idler gear 52 which meshes with the gear 53 on the main drive shaft 54, supported in the

bearings

55 and 56 secured to the auxiliary frame member 29 mounted on the main platform A. On the left hand end of the shaft 54, there is provided a pulley 58 which is connected by means of a belt, not shown, to any suitable source of power, such as the driving pulley of a motor shaft. Fixed to the idler gear 52 is provided the friction disc 61 also freely rotatable on the shaft 49. On the portion of the shaft 49 extending beyond and to the right of the friction disc 61, there is mounted the friction disc which is keyed to such shaft to rotate therewith but freely slideable axially thereof. On the end of such shaft 49 there is fixed the abutment 59 having the disc 71. Fixed to the friction disc 60 to rotate therewith, there is provided the collar 62 between which collar 62 and the disc '71 there is tensed the spring 70, which spring 70 normally maintains the friction disc 60 in engagement with the friction disc 61 so that when so engaged, the shutter 43 will be driven through the shafts 44, 49 and 54.

The operative connections for the intermittent actuator, the sprocket 10, similarly form no part of the present invention. Such operative connections are contained in the housing 45 and operatively connect with the shaft 44 so that when the friction disc 60 is permitted to engage the friction disc 61 the sprocket 10 will be actuated with the main shaft 54. Such operative connections and allied structure may if desired be of the type described and claimed in my copending application Serial Number 54,910, filed September 8, 1925, but I am not confining myself to such structure.

When it is desired to interrupt the actuation of the sprocket 10 and the shutter 43, the friction disc 60 is drawn out of engagement with the friction disc 61, at which time the idler 52 and the friction disc 61 will rotate freely .on the shaft 49 without actuating the same. For withdrawing the friction disc 60 out of engagement with the friction disc 61, there is provided the lever 64 pivoted at its lower end to the bracket 65 extending from the main frame E and having a pin 63 engaging the groove in the collar 62. The upper end of the lever 64 is pivotally connected to the link 66, pivotally connected to the lever 67, see Fig. 11, which is pivotally connected at 68 to'the arm 69 extending from the bracket member 29. The

friction discs

60 and 61 thus engage one another to actuate the shaft 44, in turn to actuate the shutter 43 and the sprocket 10, by operative connections not shown, during projection, that is, when the film travels from the reel 5 to the reel 7. when the projection period ends, the sprocket i0 is immediately stopped before the travel of the film is caused to be reversed, that is, to travel from the reel 7 to the reel 5. The withdrawal of the friction disc 60 is effected by actuating the lever 67 to thrust the link 66 to the right, thereby rocking the lever 64 about its pivotal connection with the bracket 65, causing the pin 63 to move the collar 62 and therewith the friction disc 60 out of engagement with the friction disc 61. The pin 63 has sufficient clearance in the groove of the collar 62 so that when the lever 64 is rocked in the other direction to release the friction disc 60, the spring 70 yieldably presses the friction disc 60 into engagement with the friction disc 61.

For driving the reels 5 and 7, the counter shaft 35 of the reel shaft 6 and the counter shaft 19 of the reel shaft 8 are both operatively connected to the main drive shaft 54. To this end, the drive shaft 54 has formed thereon a worm 72 in mesh with the worm wheel 73 on the counter shaft lQ, which has the bevel gear 22 in mesh with a larger bevel gear '74, see Figs. 1 and 3, on the lower end of the shaft '75, which shaft 75 is supported in the bearing 29 and the bearing 30, above which bearing 30 the shaft '75 extends and has formed on such end the large bevel gear '16 in mesh with the small bevel gear 77 on the forward end of the counter shaft 35. Since the bevel gear 76 is much larger than the bevel gear 74, it is obvious that the counter shaft 35 will be driven at a faster rate of speed than the counter shaft 19, in other words, that the rewinding action will be effected in a much shorter period of time than the projection action.

The signal cams and their operative connections and functions will now be described.

The signal cam elements (81 and 86) cooperate to initiate the actuation of the mechanism whereby the travel of the film is reversed, both to initiate the actuation of the mechanism for the change of travel of the film from the direction of travel in which projection takes place to the direction of travel in which the film is being rewound, and from the direction of travel in which the film is being rewound to the direction of travel in which projection takes place.

The signal cam elements (81 and 86) are adjustable in their position to correspond to the length of film to be projected and rewound, or to the portion of film to be projected and rewound.

At the right hand end of the platform A, see particularly Figs. 1 and 10, there is provided a cylindrical shaft '78 extending through the frame E forwardly and being supported forwardly of the frame E on the bearing bracket 79. On the shaft 78 rearwardly of the bracket 79 there is fixedly mounted a cam disc 80 having a nose 81. On the shaft 78 rearwardly of the frame E there is fixed a dial 82 having suitable graduations formed concentric to the shaft '78. Extending through the shaft 78 and frictionally maintained in place therein there is provided an inner shaft 83 which projects from the rear end of the shaft 78 and has fixed thereon a pointer 84 cooperating with the graduations on the dial 82, by means of which the relative positions of the

shafts

78 and 83 may be predetermined. The shaft 83 also projects from the front end of the shaft 78 and has fixed thereon a cam disc 85 which, see Fig. 1, is provided with a rise or nose 86.

In the present instance, the cam 85 functions to initiate the actuation of the mechanism whereby the direction of travel of the film is reversed from projection to rewind action, and therefore for convenience will be denominated the rewind initiating cam; and since the cam 80 functions to initiate the actuation of the mechanism whereby the direction of travel of the film is reversed from rewind action to projection, this cam will for convenience be denominated the projection initiating cam.

In the operation of the machine, the shaft 78 and therewith the shaft 83 will be rotated during projection and rewinding action, and the number of revolutions will be determined to correspond with the length of the film being used, that is, to the length of time required to feed the film either from the reel 5 to the reel 7 in the act of projection, or back from the reel 7 to the reel 5 in the act of rewinding. During projection, the

cams

80 and 85 will rotate in clockwise direction as viewed in Fig. 1, and during the rewlndlng action, the

cams

80 and 85 will rotate in counter clockwise direction,

To effect rotation of the

cames

80 and 85, the shaft 78 has formed thereon a worm wheel 87 in mesh with a worm 88 on the shaft 89 which is carried in the

bearings

90 and 91, Fig. 5, mounted on the platform A. Near the bearing 90 on the shaft 89 at the left hand end of the platform A, there is mounted a worm 92 in'mesh with the worm wheel 93 on the shaft 94 extending from the frame E to the ,lower end of the bearing bracket 29, Fig. 3. On said shaft 94, there is 9.11.0 mounted a large gear 95 in mesh with the smaller gear 96 on the shaft 8 of the lower reel 7, Figs. 3, 5 and 6. From the foregoing it will be seen that the shaft 78, Fig. 10, will only be actuated when the shaft 8, Fig. 3, is rotated and consequently either during the projection period when the shaft 78 is connected to rotate with the shaft 19. Fig. 6, or during the rewinding period when the shaft 8 is being ro- -tated due to the fact that the reel 7, Fig. 2, is

being rotated when the film F is drawn therefrom in its travel to the reel 5 and thereby be ing wound onto the reel 5.

The connections for actuating the shafts 27 and 28 in turn to actuate the forked member 37 and the forked member 25 drivingly to connect either the shafts 6 or 8 will now be described. These connections are controlled by the oscillating plate 97 pivotally mounted on the shaft 98, which oscillating plate is positioned to be automatically actuated by the signal cams and 85. The shaft 98 is mounted in the extension 99 of the plate 79, Figs. 3 and 10.

On the shaft 31 to the left of the shaft '75, Fig. 1, there are mounted two

rockable cam plates

100 and 101 which are pinned to the shaft 31 to be rotated therewith but movable about their pin connections with the shaft 31 so that their ends may be moved up and down relative to the shaft 31. To the right, Fig. 1, of the shaft 75, there is provided a shaft 102 journaled in the upper bearing bracket 30 and in the lower bearing bracket 29, Fig. 3. On this shaft 102 there are mounted a pair of

rockable cam plates

103 and 104 which are pinned to rotate with the shaft 102 but free to rock so that their free ends may move vertically relative to the shaft 102. The

plates

100 and 101 are provided with recessed projections 105 and 106 respectively,

Fig. 1, and the

plates

103 and 104 with recessed projections 107 and 108 respectively, Fig. 1, which projections are adapted to be engaged and cooperate with the curved cam lever 109 fixed on the shaft 75 and rotating therewith, Figs. 1, 11 and 12.

The right end of the cam plate 103 extends into the recess 110' of the link pivotally connected at its lower end to the finger 111 of the plate 97, Fig. 1. From the foregoing it will thus be seen that when the nose 86 of the cam 85 engages the pin 112 of the downwardly extending finger 113 of the plate 97 to rock the plate 97 about its pin 98, the linkgllO will be moved upwardly and thereby the recessed projection 107 of the cam plate 103 brought into the path of movement of the cam lever 109 to be engaged thereby as indicated in Fig. 1 and moved to rotate the shaft 102.

In order to facilitate raising the link 110 to the extent desired, the lever 114 is provided which is pivotally connected to the bearing bracket 29 and has a slot in its right end for receiving the pin 115 formed on the link 110. The other end of the lever 114 has a pin 116 extending through the slot 117 formed in the short lateral arm 118 of the plate 119 which is pivotally connected to the bearing bracket 29, and has a spring 120 connecting its downwardly extending arm 121 with the pin 122. The spring 120 is so connected relative to the plate 119, as shown, that it will normally maintain the arm 121 to either side of the pivotal point of the plate 119 and will cooperate with the lever 114 and the link 110 to assist the link 110 in moving to the limit of its movement either up or down, according to the cycle of operation.

A similar toggle arrangement is provided to assist in rotating the shaft 102 to the limit of its movement either in clockwise or counter clockwise direction. At the upper end of the shaft 102, see Figs. 1 and 11, there is fixed a short lever 123, the end of which is pivotally connected to the toggle lever 124 which is pivotally connected at one end to the other toggle 3'.

lever 125 which is pivotally mounted on the pin 126 extending upwardly from the bearing bracket 30. The other end of the lever 124 has connected thereto one end of the spring 127, the other end of which spring is connected to the pin 126.

The position of the several parts as illustrated in Fig. 11 indicates the position thereof at the end of projection and just immediately before initiating the rewinding action. When the cam lever 109 actuates the cam plate 103, it will cause three actions to take place,it will close the fire shutter in the extension D, it will withdraw the friction disc 60 out of engagement with the disc 61 in order to arrest ed on the shaft 129 disposed adjacent to the its.

housing extension D, the shutter 128 having formed thereon an arm 130 which has a pin at its free end extending through the slot 131 in the lever 132 pivoted at 133 to the bracket 134 extending from the housing extension D.

The lever 132 is connected by the link 136 to the pin 135 extending radially from the shaft 102. It will thus be seen that when the shaft 102 is rotated, it will actuate the link 136 and lever 132 to actuate the shutter 128, and in the present instance, when the cam plate 103 is initially actuated before the rewinding action, the shutter 128 will be actuated to close the opening through the housing extension D.

The sprocket 10 at such time will be arrested in that the friction disc 60 will be withdrawn out of engagement with the friction disc 61. This is effected by pivotally connecting the lever 67, see Fig. 11, with the arm 137 by the slot and pin connection shown, it being apparent that when the shaft 102 is actuated in a clockwise direction, the arm 137 will actuate the lever 67 in turn to actuate the link 66 to rock the lever 64, see Fig. 5, to withdraw the friction disc 60 out of engagement with the friction disc 61.

The cam plate 190 will be depressed during the rotation of the shaft 102. This depression is effected by means of the rod 138, see Fig. 1, which rod 138 is pivotally connected to the short lever 139 fixed on the shaft 140 mounted in the

bearings

141 and 142 formed on the bearing bracket 30. For guiding the rod 138, there is formed the guide plate 143 extending down from the bearing bracket 30. The other end of the shaft 140 has formed thereon the pin 144 to which is pivotally connected one .end of the link 145, the other end of such link 145 being connected to the pin 135. From the foregoing, see particularly Figs. 1 and 11, it will be seen that as soon as the shaft 102 is rotated clockwise, it will actuate the link 145 upward to rock the shaft 140 and thereby depress the rod 138 to depress the plate 100 carrying the projection 105. For normally maintaining projection end 105 of the cam plate 100 in raised position, the spring 146 is provided connecting the left hand end of the plate 100 with the pin 147 extending from the shaft 31. When the projection end 105 is so depressed, it will extend into the path of movement of the cam lever 109, so that the cam lever 109, after an interval of about three-fourths of a turn between the moment ofleaving the projection 107 and the moment ofengaging the projection 105, will cause the cam plate 100 to be actuated to rotate the shaft 31. The interval of rest before actuating the cam plate 100 is provided in order to afford sufficient time for the film F to come to rest before the direction of travel thereof is caused to be reversed.

The direction of travel of the film F will not be caused to be reversed for the rewinding action until after the shaft 31 has been rotated by cooperation of the cam plate 100 with the cam lever 109, see Fig. 12, showing the operative parts in position when the cam lever 109 has engaged the projection 105 of the cam plate 100 and is about to actuate the cam plate 100 to rotate the shaft 31.

The rotation of the shaft 31 in a counter clockwise direction, by cooperation of the cam plate 100 with the cam lever 109 will cause five actions to be effected-the forked member 37 will be actuated to cause the pins 33 to engage the pins 32 thereby to drive the reel shaft 6 with the counter shaft 35, the friction disc 18 will be caused to be withdrawn out of engagement with the friction disc 17, the film gate 148 will be caused to be withdrawn out of engagement with the film F, the stripper plate 149 will be caused to pass between the film F and the sprocket 10 to liberate the same for the return movement, and the pusher plate 150 will be caused to be set in position to engage the cam plate 104, subsequently to depress the cam plate 104 when the travel of the film F is again reversed from rewinding action to projection.

Before considering the various actions effected by the rotation of the shaft 31 in a counter clockwise direction, it may be well to mention that the cam plate 101 extends into the recess 151, see Figs. 1 and 3, of the lever 152 which is pivoted at 153 to the bracket 154 extending from the bearing bracket 29. The right hand downwardly extending end of the lever 152 loosely engages around the pin 115, and consequently when the lever 110 is raised, it will, through the pin 115, also actuate the lever 152 to depress the projection end 106 of the cam plate 101 and thus maintain such projection end 106 out of the path of movement of the cam lever 109 during its rotation when the rewinding action is initiated and until the projection action is initiated hereinafter to be described.

To insure rotating the shaft 31 to the limit of its movement and to assist the cam lever 109 in such actuation, here too a toggle arrangement is provided, see Figs. 1 and 12. A short arm 155 is fixed to the upper end of the shaft 31, see Fig. 1, the end of which arm is pivotally connected at 156, see Fig. 12, to the lever 157 which is pivotally mounted on to the bracket 158, the free end of the lever 157 being connected to the bracket 158 by the spring 159.

For actuating the shafts 27 and 28, see Figs. 1 and 6, the plate 160 having diametrically oppositely extending arms is provided, one of the arms of the plate 160 being connected by the

links

161 and 162 to the shaft 28, and the other arm being connected by the links 163 and 164 to the shaft 27. From the foregoing it will be apparentthat when the shaft 31 is rotated in a counter clockwise direction, the shaft 28 will be rotated in a counter clockwise direction to actuate the pins 33 of the forked member 37 into engagement with the pins 32 of the reel shaft 6, and the cylindrical shaft 27 will be actuated in a clockwise direction to actuate the forked member 26 to withdraw the friction disc 18 out of engagement with the friction disc 17. By this actuation of the shafts 27 and 28, it will be noted that the reel shafts 6 and 8 will now be connected to cause the film F to travel from the reel 7 to the reel 5 in rewinding action. It will also be noted at this time, that immediately that the sprocket 10, or intermittent actuator was arrested, the film F would be arrested thereby, and the friction disc 18 in its continued actuation would be caused to slip on the friction disc 17 and permit the reel shaft 8 to remain at rest.

During the same counter clockwise rotation of the shaft 31, the film gate 148 will be withdrawn out of engagement with the film F. The film gate 148, as shown in Fig. 9, functions to maintain the portion of the film F being exposed smoothly in position during the projecting action. During rewinding action, in order to facilitate the rapid rewinding of the same on the reel, the film gate 148 is withdrawn into the position shown in Fig. 9. The film gate 148 is mounted on the rod 165 which is slidably mounted in the bearing bracket 166 extending rearwardly from the frame E. The left hand end of the rod 165, see Fig. 12, is pivotally connected to the lever 167 extending through the frame E to the vertical shaft 168 and fixed thereto. The shaft 168 extends upwardly from the platform A and is journaled at its upper end in the bracket 169 extending forwardly from the frame E, see Fig. 5. The shaft 168, see Figs. 5 and 12, has fixed thereto a lever plate 170 having three

fingers

171, 172 and 173.

The finger 172 is provided with a pin extending through the slot 174 of the link 175, which link is pivotally connected at its other end to the arm 176 fixed to the shaft 31, see Fig. 12. It is thus apparent that when the pin of the finger 172 is at the right hand end of the slot 174 of the link 175, and the shaft 31 is rotated in a counter clockwise direction, the rod 165 will be thrust in the right hand direction to withdraw the gate 148 out of engagement with the film F, into the position shown in Fig. 9, Fig. 9 being a rear view of the same.

The finger 173 is connected to the link 177 which is pivotally connected to the lower end of the lever 178 which is fulcrumed at 179 to the hearing bracket 180 extending from the arm 181 formed on the frame E. The upper end of the lever 178 is connected by springs 182 "to the pins 183 on the bracket 180 disposed below the pivotal point 179 of the lever 178, whereby the springs 182 will serve to assist the shaft 31 to actuate the rod 165 to its limit of movement either to the right or left according to the cycle of operation.

The finger 171 of the lever plate 170 is pivotally connected to one end of the lever 184, the other end of which is provided with a slot 185 to receive the pin 186 of the arm 187 fixed on the shaft 102. The slot 185 is provided to permit the plate 170 to be actuated by the shaft 31 when rotating in a counter clockwise direction without disturbing the position of the shaft 102, the link 184 freely passing relative to the pin 186 until the pin 186 is positioned at the rear end of the slot 185, the pin 186 being shown in Fig. 12 in the front end of the slot 185, the position thereof before the shaft 31 has been rotated in a counter clockwise direction. The arm 187 will cooperate with the link 184 to return the film gate 148 into film engaging position upon the reversal of travel of the film F, preparatory to the succeeding projecting action.

Simultaneously with the withdrawal of the film gate 148, the stripper plate 149, see Fig. 9, will be caused to engage the film F and remove the same out of engagement with the sprocket 10. The stripper plate consists of a cylindrical section having radially extending plate portions 188 mounted on the stub shaft 189, the plate 188 having fixed thereon the gear 190 in mesh with the sector 191 of the lever plate 192 pivotally mounted on the bracket 193, the lever plate 192 having a slot 194 in its upwardly extending arm receiving the pin 195 on the rod 165. Thus it will be apparent that the lever plate 192 will be actuated with the right hand movement of the rod 165 to rock the stripper plate 149 under the sprocket 10 into engagement with the film F to remove the same therefrom. The construction and operation of this stripping mechanism may be if desired of the type disclosed and claimed in my copending application Serial Number 343,301, filed February 28, 1929, which has matured upon November 19, 1929, as Patent Number 1,736,750, such application being a division from my previously identified application Serial Number 54,910,.filed September 8, 1925.

The actuation of the rod 165 is timed to withdraw the film gate 148 and rock the stripper plate 149, Fig. 9, simultaneously with the clutching of the reel shaft 6 or slightly before so that the film F will be free to travel toward the reel shaft 6 as soon as the tension in the film F has been taken up preparatory to starting the rewinding action.

The pusher plate 150 which is raised during this counter clockwise rotation of the shaft 31 is pivotally connected at its lower end, see Fig. 10, to the arm 196 fixed on the shaft 197 journaled at one end in the bearing bracket 198 extending upwardly from the bearing bracket 29, and at its other end is journaled in the bearing bracket 199 formed on the bearing bracket 29. The left hand end of the shaft 197 has fixed thereon an enlongated pin 197 which extends upwardly through an orifice formed in the arm 200, see Fig. 12, formed on the cam plate 101. In order to guide the plate 150, the guide plate 201 is formed on the upper end of the bracket 198, and in order normally to maintain the upper end of the plate 150 rearwardly, a spring 202' is provided connected to the upper end of the bracket 198.

From the foregoing it will be apparent that during the counter clockwise rotation of the shaft 31, the shaft 197 will be rocked to raise the plate or bracket 150 so that its finger 202, Fig. 1, will rise above the cam plate 104 preparatory to engaging the same and subsequently depressing the right hand end of the plate 104 when the mechanism is to be reset for the projecting action.

The reel shaft 5 will now continue to rotate until the rewinding action is completed, this being determined by the setting of the signal cam relative to the signal cam 80. Fig. 1 shows the mechanism at the conclusion of the projecting action and just after the cam 85 has pin 204 and rocks the plate 97 about its shaft 98 to depress the finger. 111, the lever 110 will be depressed, and by its connection with the lever 152 will raise the projection 106 of the cam plate 101 into the path of movement of the cam lever 109, and at the same time through the con- 1.

nection of the arm 200, Fig. 12, with the pin 197', Fig. 1, the shaft 197 will be rocked in turn to raise the finger 202 of the bracket 150 to release the cam plate 103 and thereby permit the projection 108 to descent out of the path of move- T3 ment of the cam lever 109 so that during the subsequent rotation of the shaft 102, the cam. lever 109 will be free to rotate during the projecting action without disturbing the position of the shaft 102.

As soon as the cam lever 109 engages the projection 106 of the cam plate 101, it will rotate the shaft 31 in a clockwise direction, thereby immediately disengaging the pins 33 and 32 to liberate the reel shaft 5 and bring the friction disc 18 into engagement with the friction disc 17. At the same time, by rocking the shaft 197, the finger 202 will be caused to engage the right hand end of the cam plate 104 to raise the projection 108 into the path of movement of the cam lever 109, and by actuating the link 175 it will initiate withdrawing the film gate 148 before coming to a stop and before the pin 185 moves to the front end of the slot 185.

Thereupon after a three-fourths further turn of the cam lever 109, it will engage the projection 108 of the cam plate 104 to rotate the shaft 102 in a counter clockwise direction. In turn through the arm 18'], the pin 186 will return to the rear end of the slot 1850f the link 184. At the same time'through the arm 13'? and operative connections to the friction disc 60, the friction disc 60 will again be liberated to be pressed by the spring 71 into engagement with the friction disc 61, by means of which the drive connections to the shutter as and the sprocket 10 will be effected to drive the same. Thereupon the pin 186 in continuing its rearward movement will start actuating the link 184, whereupon the shaft 168 will be rocked in a counter clockwise direction to return the film gate 148 into engagement with the film F and to withdraw the stripper plate 149 out of engagement with the film F so that the sprocket 10 may again engage the film F.

At the same time, through the pin 135, the shaft 140 will be rocked to raise the pusher plate 138, and thereby permit the spring 146 to raise the projection 105 of the cam'plate 100 out of the path of movement of the cam lever 109 during the projecting action, and through the conneotion of the shutter 128 with the pin 135, the shutter 128 will again be opened.

At the same time also the right hand end of the cam plate 104 will be rotated out of engagement with the finger 202 so that the projection 108 will be free to descend out of the path of movement of the cam lever 109.

When the machine is used as a salesmans machine, a lecturers machine or the like, and it is desired to repeat just a short portion of the film, without repeating the entire length of the film, the machine may be instantly set to rewind the portion of the film desired to be repeated and the travel of the film again reversed to repeat the portion so rewound. This is effected manually. To this end the lever plate 97 is provided with a handle consisting of a bent rod 203 formed on the plate 97 by means of which rod 203 the plate 97 can be swung to actuate the lever 110 either upwardly or downwardly depending upon the position of the cams and 85.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention set forth in the appended claims.
