The pivoted end oiv this 1 5 -},lever is fulcrumed on the bar 13, the hub'lB being elongated and provided with a screw 19 entering an annular recess formedin the shaped front extension 50 suited to enter-a corresponding slot. in the rear end of the sleeve 46, whereby it is rigidly held in either i of two positions under thrust of the'push spring 51 which abuts against the head-52 site side of the sleeve -16 is a scraper piv-- otally supported on a pin 56 extending into the scraper compartment from a lever 5T,- the pm being operable m a slot 58 formed in the contiguous side of the sleeve and so arranged that the scraper blade may be wholly retracted or ejected, as shown in Fig.

5', by operation of the lever 57, through its handle 59, which is carved to conform i closely with the lever handle 47. 'Pivotally attached tothe plate 14 is a lever 61, having an extending head 62, adapted to be finger pressed in. raising the opposite end of-the lever and forcing the pins 63 through the plate, their function beingto raise the film end to allow the prepared end of the filmt-o be cemented to pass under and also toraise the film, after'the mending operation has been completed,

, In operation the broken ends of the film i are placed facing each other on the pins in the plates 14: and 15, at that time separated,

j and the shear'brought down by the lever 47.

- It will be noticed that the rear corners of the shear elements 40 and 41 are beveled or curved so that the shear 45 will enter, and as i the lever is .brought down the film is smoothly and squarely cut across along both shearing edges. The lever 47 is then raised, the plates 1-1 and 15 moved mward, the sleeve 46' reversed soas to bring the scraper blade 55 into operation on top'of. the films heldby the plate 15, .and as the scraper blade is pivoted near its center so it will adJust which is moved back and forth under the scraping edge by actuation of the slide 25 tlfi'ough the lever 26, thus scarifying the film surface so that the cement applied may set pgreadily upon it. The Jplates are thus edges being equal to that of the shear or. cutter 45 rigidly aflixed to one side of are verslble rectangular sleeve 46 mounted n bar, the hub 48 is formed with a wedge brought closely together, the slifd eimoved forward carrying the scraped end of-the film under the sheared end of the film held in-the plate 14, the sleeve ,again reversed and pressed firmly down upon the ends, over the shear strips attached to the plates and so held until the joint has set. When this has been done the clamp plates and 33 are released, the lever el-T. raised and the pins 63 pressed up by means\f the lever 61 freeing the film from the mechanism, which is then. ready for.another opefation.

Thus it' will be seen that a film may be quickly and neatly mended ,in an effective ma ner and 'llillgllffllllltlllt). 1t will be 'IOlJVlOHS- also that minor changes may be made in the construction without departing from the scope of the claims hereto appended. 4

I claim -1. In a'film mending machine, a pair of plates mounted to move in a horizontal plane, a toggle whereby sa1d plates are f the lever 4?. Near the edge on the oppof moved uniformly, a slide combined with one of sa1d plates, means for engaging the'ends filnrmay be passed under the opposite end.

'. a film mending machine, the combination with a pair of movable plates and means foractuating said plates to and from each other, of a lever pivoted to operate over and between said plates, a reversible sleeve mounted on said lever, a shear on one side of said sleeve adapted to cooperatively engage withthe adjacent edges of said plates, a scraper on the opposite side of said sleeve, means for raising and lowering said scraper into or out of operative engagement, means for engaging film ends with said plates and 'means for moving oneof said plates past said scraper.

3. In a film mending machine, the combination with two plates slidable in opposite directions in a horizontal plane, means for actuating said plates uniformly, a slide movsaid plates whereby the film may be sheared on both ends simultaneously, ascarifying means combmed with sa1d shear. means for raising one end ofthe sheared'film whereby the opposite end may be entered thereunder. and means for pressing the ends of the films itself to the level surface of the film end,

plate; a sleeve rotata l fly and'sl idabl y xnolunted on saidf-leven] means for-engaging said sleeve in an adjusted positien on' said lever,- a shear comb1ned wlth sa1d sleeve, said shear also' being operative as a pressing means; a scraper plvoted 111 a' recess formed 1n sald s1eeve,.means for i'emovin'g a film under said scraper a predetermined distance, and means CHARLES BIS HQFF, MIKE SmREsco. v
