The pin 5| is so located with respect to the two forward ends of the shearing members 31 are optional positions of the movable table l2 that the’ point of fastening of said spring on the table connected by a cross member 40 which serves as a handle for bringing the knife into its cutting, .will not be directly above the pin 5| when the position as shown in Figure 2, so thatthe shearing links |3 of said table are in the vertical position, in which case there would be a tendency to hold 20 20 .members 31 cut the ?lm across the ?xed shear the movable table |2 in a half-way position, but blocks 4| and 4|’. will always provide a resilient force to throw the As shown in Figure 5, the ?lm scraper con sists of a comparatively heavy slide member 42 table into either its cutting or splicing position knife 36 comprising two individual, shearing mem bers 31 which are individually rotatably hinged relative to the stationarytable II. This toggle spring 50, therefore, serves to resiliently force 25 provided with grooves 43 which extend length wise of the member, said grooves being adapted to fit the shearing members 31 of the knife 36 the movable table |2 into either‘its proper cut ting‘ or splicing position and. hold the same and give the slide member 42 a sliding engage therein until altered by the operator, and in the splicing or overlapping position of the table this spring 53 provides a resilient means for pressing the spliced joint until it is su?iciently dry to be ment therewith after it is slid thereonto from the rear. or open end of said shearing members 31. 30 Two stop members 44, see Fig. l, are provided on the base 10 in the path of, the knife 36 to engage the separate shearing members 31 thereof for the purpose of limiting its movement so that when the knife is in the cutting position, removed from the splicing table. is ?xed to the base ||l by means of screws 56 and is provided with a ?exible ‘?nger 51 which is 35 adapted to enter the open end of the shearing members 31 to prevent the slide member 42 from accidentally sliding off of said shearing members. If it is found desirable to remove the serrated 35 shown in Figure 2, the top edges of the shearing members 31 will be flush with the upper surfac of the shear blocks 4| and 4|’; , Referring now to Figure 4, a spring member 55 - A serrated tool 45 is adjustably mounted on the side of the slide member 42 to slide there with to act as a ?lm scraper when said slide member 42 is reciprocated on the shearing mem mounting of the serrated tool 45 on the side of the slide member 42 is suitably made to provide for aslight amount of adjustment of said tool tool 45 for any purpose, such as cleaning, etc., the 40 flexible spring ?nger 51 can be pressed to the position shown in dotted lines wherein the open end of the shearing members 31 is left unob structed and the slide member 42 and along with it tool 45 can be slid off and .on said shearing relative to said slide member so that it can be members 31 with ease. adjusted to just remove the emulsion coating of i the ?lm when it is reciprocated on the shearing Integral with the spring member 55 are a pair of spring arms 58 which are adapted to.extend members 31, in the position shown in Figure 2, into a pair 1'of receptacles 59_which are provided but not scrape away or injure the ?lm base. Therefore, when the tool 45 is properly positioned on the base for receiving bottles 60 of liquid re quired in splicing a ?lm. These receptacles are on the slide it will not contact the upper surface , shown as being cast on the base l0, but it is to of the shear block 4| or the shearing member 31, be understood that they may be associated. with the splicing apparatus in any suitable manner so bers 31 in the position shown in Figure 2.
