Definitions

  • a frame in the form of a casing is provided on the slide, and a roller is mounted in this casing so as to be movable therein longitudinally of the slide, and during the reciprocating movements of the slide this roller on the one hand rolls on a rolling track arranged on the needle bed and on the other hand rolls at the top on a cam member which is also loose in the casing and is directed towards the roller, and the cam member is thereby caused to move upwards and downwards and therebyto act on the actuating member of the counter and bring about the counting operation.
  • roller with two stud axles one on each side, which engage in corresponding recesses extending over almost the whole length of the frame and bounded by an abutment which is in the form of a shoulder extending over almost the whole length of the frame, so that the roller is secured against falling out of the frame.
  • cam member symmetrical about its centre, so that the cam member will always be lifted and the counting mechanism thereby actuated during movement of the slide in either direction.
  • the apparatus constructed in accordance with the invention has the advantage that the counting operation is effected quite independently of whereabouts on the needle bed the knitting process is going 011, provided only that the slide makes reciprocating movements during the knitting process. This arises from the fact that in a cer- I 2 t. tain sense the projection, that is to say the cam member located in the frame, is not arranged in a fixed position on the slide as in the previously known counting apparatus but is moved to and fro together with the slide and counter. The fact that actuating of the counter is nevertheless" possible arises from the characteristic rolling movement of the roller mounted in the frame.
  • FIGURE 1 is a view of a counting apparatus for knitting machines, partly in elevation and partly in longitudinal section,
  • FIGURE 2 is a plan view of the apparatus shown, in FIGURE 1,
  • FIGURE 3 is a view partly in elevation and partly in cross section on line IIIIII of FIGURE 2,
  • FIGURE 4 is an end elevation of the counting appara-' tus mounted on a knitting machine, of which certain parts are shown in section, and
  • FIGURE 5 is a plan view of the arrangement shown FIGURE 4.
  • recesses 4 are provided which extend over almost the whole length of the frame and are bounded at the bottom by a shoulder abutment 5 and on the two narrow sides by abutments 6 which project towards the middle of the recess 2 of the frame.
  • j 1 p A roller 26 withtwo stub axles 7 is inserted into the" interior of the frame; thesestub axles 7 canroll along'on the shoulder abutment 5, so that the roller is prevented from falling downwards out of the frame.
  • the distance of the shoulder abutment 5 from the bottom edge 8 of the frame is made such that when roller 26 rolls along on the shoulder abutment 5 the roller periphery projects slightly below the bottom edge 8 of the frame. Also, the movement of the roller 26 in the longitudinal direction is limited by the abutments 6 against which the stub axles bear when in their extreme positions.
  • the roller is provided, on its periphery, with a rubber ring 9 engaging in a channel.
  • a step abutment 12 is provided near the top end of the inner surface 11 of each end wall 10 of the frame; the ends 13 of a cam member 14 are supported on these step abutments.
  • This cam member is made symmetrical about its centre line 15; it is provided with two downwardly directed run-up ramps 16 at an obtuse angle to one another.
  • the peak 17 of the cam member, which projects furthest downwards, is in the middle of the cam member.
  • the whole top surface of the cam member is flat.
  • run-up ramps 16 do not extend over the whole length of the cam member but merge into flat end surfaces extending parallel to the top surface 19 of the cam member.
  • the frame 1 is closed at the top by a cover 20 on which a counter 21 of known construction is mounted.
  • a counter provided with a plunger pin 22 has been found particularly advantageous.
  • the plunger pin passes through a bore 23 in the cover 20 and touches the top surface 19 of the cam member.
  • the counter has a number of counting discs 28 which are rotatable about axes and are visible through windows 29 provided in the casing of the counter 21.
  • the frame 1 is secured laterally to the lock plate 30 of the lock 24.
  • the lock plate 30 has angularly bent portions 31 engaging in external guiding grooves in lock guiding rails 32 secured to the top side of the needle bed 27.
  • Sinkers 34 are mounted for pivotal movement within slots 33 of the needle bed.
  • Latch needles 35 are arranged so as to be easily displaceable in further slots between the sinkers 34.
  • a cam 37 mounted in the lock casing acts on the inner ends 36 of the sinkers 34, and during the movements of the lock each sinker impinging against the cam is pivotally moved by the cam.
  • a cam disc 38 used for adjusting parts of the lock, and a handle 39 used for moving the lock, are secured to the lock 24.
  • the frame 1 is secured to the lock 24 in such a manner that when the lock is set in place on the knitting apparatus the bottom edge 8 of the frame is slightly above a rail 25 secured to the needle bed of the apparatus. In this position, the rubber coating 9 of the loose roller 26 rests on the rail 25 and there is a slight gap between the topmost point of the roller and the flat end 18 of the cam member.
  • the roller 26 rolls on the rail 25 and at the same time the stub axles 7 move in the direction of the arrow Brelatively to the frame 1. This causes the top of the roller to leave one of the flat end surfaces 18 and run on to one of the ramps 16, rolling on this ramp. Because of the inclination of the ramp the left hand part of the cam member 14 disposed loosely in the frame is first lifted until it touches the bottom surface of the cover 20. Then, as the slide continues to move, the right hand end of the cam member is also lifted and the plunger pin 22 is moved upwards whereby the counter is actuated.
  • the roller has rolled past the peak point 17 of the cam member and rolls off on the other ramp, and finally reaches the right-hand position shown in broken lines, in which the top edge of the roller is underneath the right hand end surface 18.
  • the stub axles 7 now bear against the right hand step abutment 6, so that as the slide continues to move the roller rolls in the apex of the angle between the shoulder abutment 5 and the step abutment 6 without imparting any movement to the cam member. Instead, both ends of the cam member rest on the abutments 12. It is only when a change of direction of the movement of the slide takes place that the roller will again move in the frame in the manner described above, but from right to left, and the cam member will again be lifted and the counter actuated.
  • An automatically operated counting mechanism for counting rows of stitches on hand knitting machines provided with a needle bed, comprising a reciprocating slide, a casing secured to said slide, a loosely mounted cam member adapted for up and down movement in said casing, a rolling track arranged on said needle bed, a roller mounted in said casing for longitudinal displacement on said rolling track and on said cam member to cause said cam member to move upwardly and downwardly upon longitudinal displacement thereof, a counter mechanism secured to said casing, said mechanism including a counter actuating pin in contact with said cam member.
