  • My present invention relates to a machine organized to trim selvage edges from a moving fabric strip, and contemplates, as its principal object, the provision of a trimming mechanism operable upon the meandering edge, or edges, of a fabric strip to sever the selvage strands or cords therefrom land to a. uniform width, regardless of any sinuosities of the fabric edge which result either from irregularities of sidewise movement compounded with the forward movement of the passing fabric strip, or from undulations inherent in the edge of the strip, and thus to avoid the production of anundue amountof waste fabric, such as would result were the knives set in fixed cutting position.
  • the essential obj ect of the invention has been to provide a trimming mechanism, which includes knives transversely shiftable with respect to the untrimmed fabric, and guide means arranged to engage the meandering edges of the fabric'for lateral shifting in accordance with the undulations of such edges. Additional mechanism is proposed that will so copulate each knife with one of the guides that all fabric-imparted movement of the guides may be positively transmitted to respective knives to effect corresponding and equal changes in their position.

  • the lower base element 19 slidably supports the entire carriage upon a dove-tail rib 22 formed upon the upper face of a xed bracket 23, which is supported in lateral projection from-each main side-frame of the machine structure.
  • the top slab 21 may be arcuately adjusted upon this base element 19, to which it is secured by fastening studs 24 engaging in arcuate slots as shown. Angular horizontal adjustment is thus secured to thetrimming knives, in respect to the adjacent fabric edge,
  • Linear horizontal adjustment for the trimming elements is secured by mounting the upper base element 18 .upon a dove-tail lrib 25 formed upon the lower top slab 21,
  • the top slab 20 is hingedly mounted upon itsbase element 18 through the medium of the pivot rod 27, which thus allows for depression of each knife from engagement with the fabric.
  • Latch means 28, which-may consist of any preferred association of a spring pressed catch with a keeper or any equivalent thereof are provided to normally prevent the carriage part 20 from moving about the hinge 27 connecting it to its lower part 18, although the catch may be readily released by proper manipulation of the obvious sort.
  • each tube sleeve 16 there may be supported a shelf 29 which partially incloses the knife in order that the fabric edge may be consistently fed to the latter, accordingly eliminating the necessity for any vertical linear adjustment of the knives.
  • the side frames 32 of the machine structure rest upon a suitable base or bed-plate and are each formed with a vnumber of integral bearing sleeves 33.
  • Corresponding bearings of the opposite side frames are in'transverse alinement across the fabric for the support of a plurality of rolls 34 over which the fabric passes in traveling through the trimming machine.
  • Horizontal ledges or webs 35 Fig 2) connect the-front and rear parts of each side frame and upon these and intermediate auxiliary frames 36 are supported the housings or casings 37, one at each side of the machine, as illustrated in Fig. 1.

They project above the roll to provide a sufficiented T-shaped extremity 39 'which is securedupon the central portion of an arm 40 extended from the body of the carriage E.
  • This carriage is mounted within a suitable casing 41 formed along one side with an elongated aperture 42 (see Fig. 8) through which the arm 40 passes for exterior attachment to the guide arm 39.
  • the top plates l 43 of this carriage casing are formed with grooves which receive the knife-edged peripheries of a pair of guide wheels 44 which are supported centrally of the carriage to project above the top thereof.
  • To each wall of the casing 41 there is secured a number of projecting arms 44 which support rails 45, also having grooves to receive the knife- .edged peripheries of the guide wheels 46, which are mounted upon suitable trunnions projecting from the ends of the carriage E and in the same vertical planes of the central wheels 44.
  • a weight E (Fig. 7) is suspended from a flexible element e which. is attached at its other endto the controller carriage and intermediately trained over the pulley c so that the gravitational force of the weight is translated into a horizontal force which acts to insure a positive contact between theguides and the fabric edges.
  • the carriage E is provided with dependent skeleton side plates 47, the corresponding extremities of which are connected by any suitable attaching means 48. Centrally these side frames are connected by a trunnion 49 upon which is supported for oscillation a T-shaped member 49.
  • the stem of the T is relatively short and it occupies an inverted position upon its mounting trunnion 49. At its upper extremity, it is transixed by the pin 50 which serves as a pivotal point for the loose connection of the member 49 to an arm 51, through the medium of the plates 52 dependent from the extremity of the arm 51 and slotted to rest upon the pin 50 (Fig. 1l).
  • This arm projects longitudinally through the carriage casing 41 and is then bent at right angles thereto for suitable connections denoted by the numeral 53 with a bracket 54 jutting out from the adjacent side of the motor and knife carriage C.
  • the T-shaped member 49 embodies the selective control which governs the direction of movement of the trimming knives in accordance with the direction in which the guides are actuated.
  • Each extremity of the inverted T head is enlarged to provide a supporting sleeve 55 for a contact pin 56 which is adjustably maintained within its sleeve through the medium of the set screw 56 or equivalent securing member.
  • Supported within the housing 4l are a pair of mercury tanks 57 and 58 placed in alinement directly below the carriage E and mounted upon, insulating pedestals The placing of these tanks in respective electrical circuits will later be discussed in connection with the wiring diagram of Fig. 10.

  • the shaft 60 supports the magnetic clutch member 66 at the unsocketed extremity'and the shaft 61 similarly mounts the magnetic clutch member 67.
  • These magnetic clutches are of a type well-known to the electrician and are provided with the usual brushes 66, pivotally .mounted by the casing back wall, and
  • Equal gears 68 and 69 are respectively carried by these clutches and in an intermeshing relation.

  • the energization of this magnetic clutch serves to draw the opposite clutch member 75 into mating relation therewith, thus determining a clockwise movement for the shaft 73.
  • This shaft motion is directly transmitted to the superposed shaft 72 through the train of ears 76, 77 and 78, the center one of which 1s an idler mounted upon a stub shaft 79 between the shafts 72 and 7 3 which respectively carry the terminal gears of the train.
  • a drive gear 80 is carried by 'the shaft 72 and is thus rotated in the clockwise direc-tion ofthe shaft 61 to drive the element H, through the pinion 81, in the countereclockwise direction of Fig. 6 which results in an advancing movement of the carriage C along its bracket track-way 22 toward the fabric edge at the right of Fig. 4.
  • Energization, on the other hand, of the magnetic clutch 66 which. is continuously driven in a counter-clockwise direction by the motor G, through the gears 68 and 69, serves to bring the clutch member 82 into mating relation therewith, thus turning the shaft 72 and the gear 80 in a counter-clockwise direction, and consequently the gear 81 clockwise or, in an opposite direction to that determined by an energization of the clutch 67.
  • the driving element H is then reversely rotated to retract the carriage C from the fabric edge.
