Definitions

  • the present invention relates to plaiting machines in which an upper and a lower knife are pivotally mounted on a common axle and are reciprocated towards and away from the drums in a forward and a backward stroke.
  • the lever causin the pivotation of the knives is controlled by a cam provided with removable bosses, in such manner that according as the said lever makes cont-act with a raised or a concave cam portion, the knives will assume the upper or lower position, or inversely.
  • the pivotation of the said knives is effected by means of a member positively driven which causes said knives to be pivoted towards one of the drums during one of said strokes against the action of yielding means urging constantly said knives towards the other drum, means bein; adapted to relieve the knives from the action of the member positively driven.
  • the said relieving means may be controlled by a cam provided with fixed or removable bosses, known per se.
  • l i l is an elevational view of the machine. .l "s a plan view showing the device for tr-oi oi the movable stop by means of cum provided with bosses. I15 l 23 shows the sector for holding the said device.
  • the upper andlower knives of the machine, 1-2 are supported by the checks 3 and are given a reciprocating motion by these latter, whereby they are moved from or towards the drums l and
  • the cheeks 3 together with the knives 1 and 2 are pivotally mounted on the axle (3, so that the said knives may slide upon the upper forming plate 7 or on the lower "forming plate 8.
  • This movement of pivotation of the cheeks 3 and the knives 1 and. 2 is effected by means of a pm or rod 9 mounted on the plate 10 pivoted on the axle 11; the said pin 9 cooperates with a guide 12 secured to the cheeks 3 and preferably formed 260,498, and in France December 30, 1927.
  • the pivoted plate 10 is actuated by a lever 15 pivoted upon an axle 16 and connected with the plate 10 by means of the sliding member 17 whose position may be adjusted in the slot 18 of the plate 10.
  • the lever 15 is controlled by the spring 19 in such manner that the roller 20 mounted on this lever will make contact with the rotatable cam 21having a continuous out line.
  • the said cam has two curved parts, one of which a-b-ewhich is relatively nearer the centre of the caimiwhilst the other part a(Z-c is farther removed, the construction beingsuch that when the roller 20 makes contact withthe respective curved parts of the cam, the knives l and 2 will, be raisedor lowered.
  • the speed of rotation of the cam 21 is regulated in such manner thatthe outline a-b-c will correspond to the forward motion of the knives towards the drums 4 5, and that the outline ad-c will correspond to the back motion of the said knives with reference to the drums.
  • the machine will constantly produce overlapping plaits.
  • the hook 22 is movably mounted on the axle 23 so that it may make contact with the catch 24 or may move out of contact therewith.
  • the hook may be placed in or out of contact with the catch 24 by means of cams provided with fixed or movable bosses, wherey we may obtain a succession of plaits in a stated order so as to produce various patterns on the fabric.
  • the sleeve 26 carrying a contact roller 27 is slidable 0n the axle 23.
  • the said roller may be made to coincide with one of the cams 28, 29, 30, 31 mounted on the axle 32 which is parallel with the axle H3, or it may be placed in the space
  • the said cams may be provided with removable bosses, and they are preferably constructed according to the U. S. Patent No. 1,612,500.
  • the said cams may also consist of discs with fixed bosses.
  • a disc may offer alternately a boss and a concave part in order to obtain box plaits.
  • the hook 522 is engaged with the catch 24, but when the said roller engages a raised part, said book will be released from the catch.
  • the cams such as 28, 29, 80, 31 may be used in any suitable number, and in this manner the plaits will succeed one another in any desired order. For instance, if box pla-its are to be formed, the roller 27 is made to coincide with a cam having alternately a boss and a concavity. When the roller 27 is brought into the space between any two cams, the hook 22 under the control of the spring 26 will engage the catch 24, so that the machine constantly produces underlapping pla-its.
  • the roller 27 may be operated by a lever 33 which is pivoted to the sleeve 26 and is pivotally mounted on a ball joint 34 (or the like) by which the lever may turn upon dif' ferent axes.
  • the said lever may beheld in the respective positions of the roller 27, by means of a sector having the notches 35, 36, 37, 38, 39 in which the lever can be fastened.
  • the notches 36 to 39 correspond to the respective cams 28, 29, 30, 31, whilst the notch 35 corresponds to a lower position of the roller 27 in which the hook 22 engages the catch 24.
  • the sector comprises the raised parts 40, so that in passing from one notch to another, the lever is obliged to pass over the raised parts and it accordingly rotates the sleeve 26, and the roller 27 is thus raised out of contact with the cams 28 to 31. Vith the roller 27 in the raised position, the lever 33 can be used to bring the said roller into any position without meeting with the cams.
  • the controlling lever 33 may in turn be automatically controlled by a cam of suitable outline.
  • the plaiting machine herein specified has many advantages over the known plaiting machines, which may be stated as follows:
  • the oscillating motion of the knives is obtained by the control of a cam which has a continuous outline and is given a regular rotation, thus providing for the positive control of the knives, and we are thus enabled to optionally eliminate the elastic combination 18, 14:.
  • the bosses on the cam 21 may be as considerable as desired, and this al'li'ords the rcduction of the lever gear which was necessary when the lever 15 was controlled directly by a cam with removable bosses.
  • the position of the knives is controlled by the complete rotation of the cam 21, and not as in the machines employing a cam provided with bosses and having an intermittent rotary motion, by a rotation through a very small angle corresponding to half the angular distance between two successive bosses, and we thus obviate the shocks in the machine, so that it will operate 1n a very easy manner.
  • the said bosses may have a relatively small size, for in the present machine, the bosses serve only to release the stop 22. whilst n the known machines the bosses must pro- ]ect considerably from the surface, sin cc they must provide for the whole amount oi. motion of the knives.
  • a plaiting machine the combination of two plaiting upper and lower drums, an upper and a lower knife, a pivoted frame supporting said knives and adapted to be pivoted with said knives towards the upper and towards the lower drum and to be reciprocated towards and away from the drums in a forward and a backward stroke, elastic means adapted to urge said frame with said knives towards one of said drums, controlling means adapted to pivot said frame with said knives to *ards the other drum against the action of said elastic means, and movable locking means adapted in their operative position to hold permanently said frame with said knives towards said other drum.
