This is accomplished autonmtice lly as follows. i-The outerend-QQ of the film. from the reserve; roll '7 -9: is laid l upon the a anvil 1-6 awithya. .met slli c fastener .23; projecting through it having. the sharp ends. 24; gprojecting upwardly. The

die 15, carried by n plunger 25,: is normally held raised-layup lightspring. 26', but mey be caused tostrike the. fastenerhbencting .over the sharp ends thereof (thus uniting. the film hands)- by 1 a gravity .uctustcd striker, his striker. :1 hall,"isgwnormally held. bya .lutclrl which may betrippedhy .the fil n band F from the supply reel, as will be hereinafter described. The striker 27' falls upon the end 28 of the die causing it to function, falling through the guideway 29. After depressing die 15, the striker rolls down the exit passage 30 which obviously will admit the ball when the die is depressed.

This permits the spring 26 to quickly raise die 15 so that the film uniting operation consumes very little time, being almost instantaneous. The striker can then be removed through the opening 31, and repositioned through the mouth 32 of the guiding tube 29. In order to trip the latch member 28 the following mechanism is used. The film. band F passes over the

twin sprockets

12 and 13, as before described, the reason for this being that the short length of film 33 is supported by the sprockets; On this length of film theactuating roller 34 is held in the position in Fig. 1, wherein it maintains the bell crank lever 35 in an operative position. Roller 34 is supported on an end 36 of the lever 35 and the other end 37 is adapted to strike the tripping member 38 when the film end reaches roller'12 permitting roller 34 to swing! in the direction of the arrow, Fig. 1. The latch 28 is pivoted at 39 to the frame. The end 10 of this member contacts with the tripping member 38, which may swing about pivot 4L1. As part 37 strikes 38 it is swung in the direction of the arrow Fig. 5, permitting latch 28 to swing in the direction of the arrow, and allowing the striking member 27 to fall. The cam surface 42 contacting with part 43 when the parts are being set swings member 38 about its pivot so latch 28 may return to its set position. The weight of the tripping member 38 normally holds it in the position shown. V I 1 e As will be seen'fro-m Fig. 2,

sprockets

12 and 13 are carried by a frame 45 having an operating handle 46 which may be used for removing or inserting the squared plug 47 into aperture 48, as the removal of these sprockets greatly facilitate positioning the film from the reserve to the supply position.

It is necessary to cause'the film to momentarily pause just as the die 15 strikes the anvil 16 when the film ends are clipped together, this being accomplished by a flexibly driven sprocket 19. As may be seen in Fig. 3, this is mounted on a shaft 50, supported by bearings 51 of bracket 52.

A sprocket wheel 53 is mounted to turn freely on shaft 50, being moved constantly by a chain 54. The sprocket moves a cup shaped member 55, to which is fastened an end 56 of aspring 57. The other end 58 is affixed to shaft 50, so that the shaft derives its entire movement through the spring, which is partially tensioned when driving. A ratchet wheel 59 is atfixed to the shaft and may be engaged a pawl 60 to stop the shaft momentarily, thus increasing the tension on spring 57. When released, the spring will drive shaft faster than the normal driving speed for a moment, so that the only effect on the movement of the film band is to vary, for the moment, the position of the floating roller 20, as sprocket 21 drives the film band from this variable supply constantly at an even speed into the machine.

Pawl pivoted at 61 is actuated through the arm 62, which engages a pin 63 on the die 15, so that as the die approaches the anvil pawl 60 will momentarily engage ratchet wheel 59, thus stopping the sprocket operation, he moves the roll from hook 5 up incline 6 to hook 7. This does not in any way disturb the feeding of the film which continues during the operation. Having previously removed

sprockets

12 and 13 by the handle 16, these are again positioned with the film running over them so that roller 3a is thus returned to its operative position and with it bell crank lever 35 is also moved to operative position, after returning the latch 28 to aposition in which the striker 27 is held ready for the next operation. After the operator places a new reserve roll in place in hook 5 and threads the end of the film over the fastener on anvil 16, he may attend other machines.

Having thus described my invention,

,what I claim as new and desire to secure by Letters Patent is:

1. A film supplying mechanism comprising, a reel of supply film, means for drawing film from said reel, a reel of reserve film, and means controlled by the supply film for connecting the outer end of said reserve film with the final end of said supply film. i

2-. A mechanism as in claim 1, in which the connecting means attaches a fastener to said ends of said films.

3. A mechanism as in claim 1 in which the connecting means clinches a pronged metal fastener in said ends of said films.

4. A film supplying mechanism compris ing,'a reel of supply film, a sprocket for drawing film from said reel, a driving element and a flexible member connecting the driving element and the sprocket, a reel of reserve film, means including the flexible member for permitting the sprocket to pause momentarily, whereby a dwell is produced in said drawing, and means for automatically connecting the outer end of said reserve film with the final end of said supply film during said dwell.

5. A film supplying mechanism comprising, a reel of supply film, means for drawing film from said reel, a reel of reserve film, means for producing a dwell in said drawing, means for attaching together the outer end of said reserve film and the final end of said supply film during said dwell, both of said means being controlled by the supply film.

6. A film supplying mechanism comprising a reel of supply film, means for conducting film from said reel, along a path, a reel of reserve film, a support adjacent said path for holding the outer end of said reserve film and a bendable fastening element attached to the film, and means cooperating with said support for automatically connecting said outer end of the reserve film to the final end of said supply film by bending said fastening element over upon the supply film.

i. A film supplying mechanism comprising a reel of supply film, means for conducting film from said reel along a path, a reel of reserve film, a support adjacent said path for holding the outer end of said reserve film and a metallic clip, and means cooperating with sald support for autoinatically completing a connection between saidouter end of the reserve film and said final end of the supply film by clinching said clip.

8. A film supplying mechanism comprising a reel of supply film, means for conducting film from said reel along a path, a reel of reserve film, film fastening devices adjacent said path, a source of energy for actuating said devices, and means controlled by the approachof the final end'of said supply film for releasing energy from said source to actuate said devices to fasten said final end of the supply film to the outer endof the-reserve film. V I

9. A film supplying mechanism comprising a reel of supply film, means for conducting film from said reel along a path, a reel of supply film, film fastening devices in operative position With respect to said path, the outer end of said reserve film and a fastening element heing supported in said devices, and means controlled by the approach of'the final end of said supply film for actuating said devices to apply said ele ment in fastening relation tosaid final end of the supply film and said outer end of said reserve film.
