Definitions

  • the present invention has for its object a knitting machine adapted to produce a stitched fabric and that is intended more particularly for domestic or handicraft use.
  • the 'carri'age that is started moving through the agency of a head controlled from the outside, has for its object to'pr'oducethe forward and rearward movement of the sliding hooks that are constrained to reciprocate with reference to the rectilinear comb, with a view to positioning the thread in zig-zag formation between the teeth of the comb and the sliding hooks and thereby, to initiating the successive rows of stitches afterthe formation of the first row.
  • the present invention has for its objectto brin'g various improvements to the machines of the abovetype, chiefly for making its structure simpler, its operation more reliable and more accurate, its handling and transportation easier, these different improvements havingvfor their result anincreased production. t.
  • the carriers on which the ends of the removable rectilinear comb rest are rigid each with an arm that is adapted to pivot round an'axis perpendicular to the plane in which the hooks are shifted and that is at a comparatively large distance from the corresponding carrier, which allows adjusting the position of the teeth of the comb with reference to the sliding hooks and consequently provides for an adjustment of the stitch-size.
  • the above mentioned comb carriers are provided with a 2,733,582 Patented Feb. 7, 1956 ice pointer cooperating with a scale carried by the frame or casing of the machine, whereby it is possible to obtain an accurate adjustment and a marking of the position assumed by the rectilinear comb.
  • each of the carriers of the movable rectilinear comb is provided on its inner surface with a recess adapted to cooperate with a stud carried by the corresponding end of the comb, said recess having two slopes one of which allows producing accurately a smooth rising movement of the rectilinear comb with a view to releasing the thread from the hooks while the other slope forms with the former slope a sort of funnel which allows readily posi tioning the comb and releasing it when it is to be turned round longitudinally end for end; at the same time each comb carrier is designed in a manner such that the comb may be readily turned upside down, i. e.
  • the comb body carrying the teeth may be positioned higher'than the teeth that are directed downwardly with a view to allowingexamination of the knitted material, in which case the studs on the comb engage further recesses in the carriers that serve as abutmentsengaging the comb with a view to preventing the latter from dropping out too easily.
  • the thread-carrier associated with the carriage, for laying the thread in the sliding hooks at the moment of their forward movement whilersaid carriage is being shifted, is provided with a rectangular head through which it may be taken hold of easily in order to impart to the carriage a translational movement.
  • the rectilinear comb includes a wooden core which allows an easy mounting and discarding of the teeth.
  • the machine may also include a parallelepipedic frame or casing housingalmetal plate matching the inner shape 'ofthe frame and carrying thedifierent members contained therein, while vertical slots servingas guide-ways for the' sliding hooks are provided in the plate in register with further slots provided in the front wall of the frame and the rear raised ends of said hooks are guided during their slidingmovementinside a transversely grooved metal sheetand their lowermedial portions are guided inside another transversely grooved metal sheet; said two grooved metal sheets are secured to the first mentioned carrier plate and are rigid furthermore with a rail guideing thefcarriage producing the, forward and rearwad movementof the sliding hooks, which latterrest on a U-shapedrnetal sheet carried by springs bearing on stays connecting the two vertical flanges of the metal carrier plate.
  • V r a Lastly, the machine may be laid on feet that are preferably removable and that include bearing surfaces in spaced formation, that allow giving the front surface of the frame a slope that furthers the execution of the work.

  • Fig. 4 is a corresponding plan view.
  • the machine is constituted by a parallelepipedic elon-' gated frame or casing 1 including a front wall 1a a rear metal plate 3, said edges being fitted between the edges of a medial opening of the cover lb that are folded at right angles; along said slot 4 the carriage or the like driving .member .described hereinafter is adapted .to move.
  • 'Thelfront wall la-of the casing is provided with vertical slots #5 through whichprojectthe sliding books 6, which latter rest on alongitudinal flange 7 .formedton the wall 1a .of the casing.
  • the metal-carriergplate .3 is also ,provided :with vertical slots 8 registering with the slots 5.

  • the members withwhich the'slidinghooksfi cooperate for the formation of stitches maybe constituted for instance by 'a-:series tof..metal rods a'ssuming the shape of nails or teeth 14.
  • the latter are connected so as to' form at rectilinear removable comb 15 that may be constituted by a tubular body inside which is housed a woodencore 16 that allows the readymounting-and dismantling of the nails or teeth :14 without it being necessary to resort to anyispecial.devicefor these operations.
  • comb l5t carries at-ea'ch end-a plate 17 secured to the'wooden core 16 through the 'agencyof'a screw 18 (Fig.3), said'platebeing provided 'with'astud 19 hearing against the bottom of-a 'V' shaped recess '20 formed in thei innersurface of the corresponding support '21 (-Fig. 4).
  • Said spindle"23 is 'carried'by a plate '24 rigid withthe casing -1.
  • the shifting of the supports 21' is guidedand limited by aslot'25 provided in the arm 22 and cooperatingwith a threaded'pin 26 screwed'into the plate 2 4; the" large-'radiusof curvature assumed'by the slot25 as allowed by the locationof'the spindle23 ensures substantial"linearity'ofthemovement ofthe carrierZl in a horizontal plane.

  • each stud 31 bears against the adjacent carrier 21 so as to hold the rectilinear comb 15 at a certain distance from the front wall 1a of the casingil .(Fig. 3).
  • the teeth 14 are located, when the comb 15 is in its normal position, in a manner such that the hooks 6 may lie inregister with'the intervals betweenzsaid teeth.
  • the hooks 6 are actuated in a manner such'asto execute in alternation a forward and a rearward movement with reference :;to the comb .15, this reciprocatingsmovernent being produced by a.driving sliding .member such as the carriage shown at32 (Fig.2) which'is adapted to assume a reciprocating movement throughout the length of the machine. This movement is produced through handactuation of the head or knob 33, assuming the shape of a parallelepiped and forming a handle 'forlthe carriage. The said carriage 32 slides when thus controlledlovera longitudinal rail '34 carried by-the groovedmetalsheet 10.
