Definitions

  • the reading and the press action of the needles are carried out before the hooks are taken over by one or other of the claw frames, that is to say in their high and / or low positions.
  • the press In the case where the hooks have a double branch, the press must be maintained until the claws have been crossed. This requires a very rapid movement of the paper which must occur in the very short time during which the press is released. In addition, this prohibits turning the mechanics upside down.
  • a double mechanical lift according to the invention comprises hooks affecting the general shape of a tuning fork, that is to say that they have a hairpin part extended downwards by a straight rod at the end of which is attached the harness.
  • Each branch of the hooks is provided with a deformation or bump directed towards the outside or the inside and suitable for cooperating with a racket whose bars or rods ensure the appropriate position of the branches of each hook by cooperation with his bumps.
  • the press is not necessary for crossing the claws, it can be released as soon as the hooks are taken over by the corresponding claws. This way we have a much longer time to move the paper.
  • Fig. 13 to 24 are views similar to those of FIG. l to 12, but corresponding to a variant in which the shape of the hooks is modified so as to correspond to an inverted press, that is to say that from rest the hooks are actuated by the claws only they are pressed.
  • Fig. 25 to 27 show an alternative embodiment of a hook as illustrated in FIG. 1 to 12 but intended to operate with a single racket.
  • the hooks used in accordance with the present invention have the shape of a tuning fork, that is to say that they firstly comprise an upper part 1 in the form of a hairpin and a lower rod 2 which starts from the rounded connection 3 between the two vertical branches 4 and 5 of the part 1.
  • the lower end of the rod 2 is associated with a ring 6 intended to rest in a cavity 7a of complementary shape formed in the board of usual background 7 of an armor mechanism.
  • a heddle 8 shown in broken lines.
  • each of the branches 4, 5 of the upper part 1 of each hook is turned over so as to constitute a spout 4a respectively 5a.
  • These spouts are intended to cooperate with the claws 9a, 10a of a lower frame 9 respectively upper 10.
  • the claws 10a of the upper frame can also come below those 9a of the lower frame. Since such an arrangement is well known in practice, it is not necessary to describe further the production of such frames. It will be observed, however, that the figures of the appended drawing are schematic and do not claim to represent in a precise manner how the claw frames intersect.
  • the branches 4, 5 of the upper part 1 of the hooks are provided with camberings or bumps 4b, 5b oriented towards the outside and located at the same level.
  • the mechanism according to the invention also comprises a racket 11 comprising rods 11a, 11b located on either side of the branches 4 and 5 of the hook.
  • Two grids 12 and 13 respectively have also been provided, the bars 12a, 13a being arranged on either side of the racket 11 respectively above and below the rods llb, that is to say that the said bars are on the side of each hook opposite to that which faces the direction of the normal press.
  • the rod 2 of each hook is provided with a spout 2a intended to cooperate with a blade 14 when it is desired to maintain the hook in the open step position.
  • a needle 15 comprising an eyelet 15a crossed by the rod 2 of each hook.
  • the elevation of the hook results in cooperation of its branch 5 with the claw 10a of the frame 10 in the downward movement except during the period of crossing of the claws.
  • the bump 5b cooperates with the bar 12a.
  • the hook can be grasped by the claw 10a of the upper frame 10 being in its low position, since then the spout 5a of the branch 5 of said hook is located above the claw considered (fig. 7). At this position, the hook is also stable since the hump 5b of the branch 5 is in abutment against the bar 13a of the grid 13.
  • the hook gripped by the claw 10a then rises (fig. 8). During its ascent, its position is stable due to the fact that its branch 4 rubs against the claw 9a of the frame 9, while the rod 2 slides along the blade 14. In the high position the hook is supported by the bump 5b of its branch 5 against the bar 12a of the grid 12.
  • a hook according to the invention is not interested in the rise of the claws 9a of the lower frame 9 because, as illustrated in FIG. 11, in the position of not closed, the bump 4b of the branch cooperates with the rod lla of the racket 11. This causes a deformation of the branch 4 in the direction of the other branch 5 so that the spout 4a of the first cannot be actuated by the claw 9a during the climb.
  • the aforementioned deformation of the branch 4 is made possible by pressing the bump 5b of the branch 5 against the rod llb of the racket 11.
  • the hook illustrated in fig. 13 to 24 is of the same kind as that described above, except that it is intended for reverse press armor mechanics. By this is meant that the hook remains on the bottom board, that is to say in its low position if it is not subjected to a press, while in the normal press the hook is gripped by the claw of the one or the other of the two frames without action of the needle on itself.
  • the hook illustrated in fig. 13 to 24 is of the same type as the previous one, but its hairpin part has two branches 16 and 17 of shapes different from those 1, 5.
  • the bottom of this part 1 comprises two close rectilinear elements 16a, 17a which then move away to form the parts 16b, 17b whose free ends are arranged in the form of beaks 16c, 17c turned outwards like those 4a, 5a.
  • the part 16b of the branch 16 is provided with a camber or bump 16d oriented inwards.
  • a racket with two bars referenced 18 is placed between the arms 16, 17 at their most spaced apart portions 16b, 17b. We have referenced 18a, 18b two superimposed bars of the racket 18.
  • Illustrated in fig. 16 the position of the hook and claw frames at the time of their crossing, that is to say when the step is closed.
  • the lower frame 9 descends while the upper frame 10 rises.
  • the part 17b of the branch 17 is guided by the two bars 18a, 18b of the racket 18 due to the deformation of the hook due to the action of the claw 9a on the spout 16c.
  • the claw frames are crossed without any action of the rising frame relative to the hooks.
  • Fig. 19 shows the hook in the low position as in fig. 13 but with the upper frame allowing the hook to be raised by cooperation of its claw 10a with the spout 17c.
  • the claw 10a to hook the spout 17c it is necessary to bring the latter above it by making a movement (in the direction of the arrow in fig. 20) by the needle 15.
  • the branch 16 of the hook pivots around the bar 18b by cooperation of its hump 16d which allows the displacement of its other branch 17.
  • the top of the latter presses against the claw 10a above which is place the beak 17c.
  • the hook can then be raised by the ascent of the upper frame 10 to arrive at the position of fig. 21 which corresponds to the position of fig. 15 except that it is not the same frame which raised the hook.
  • the latter is stabilized in a similar manner.
  • the position illustrated in fig. 22 illustrates the crossing of the frames 9 and 10 when the hook descends with its beak 17c associated with the claw 10a. Only the branch 17 of the hook is deformed since it is attached to the claw 10a, the claw 9a rises without hanging the spout 16c.
  • Fig. 23 illustrates how, thanks to a displacement of the needle 15 or press, the beak 2'a comes to be located above the open pitch blade 14 'so that the hook subjected to the action of the claw 10a of the frame 10 is not lowered by it but remains in the high position, as illustrated in fig. 24.
  • the racket 18 and the guide of the upper parts 16b, 17b of the branches 16, 17 by means of the claws 9a, 10a makes it possible to keep the hook stable in the open step position.
  • the needle 15 no longer cooperates with the lower rod 2 of the hook but with its two branches 4, 5 thanks to two eyelets 15b, 15c which each of the abovementioned branches crosses.
  • the spout 4a of the branch 4 is located above the claw 9a of the lower frame 9 when the hook is in the rest position against the bottom board 7.
  • the elevation of the frame 9 causes that of the hook.
  • the two branches 4, 5 of the hook are brought together by cooperation of their bosses 4b, 5b with the bars lla, llb of the racket 11 so that the branch 5 of the hook which is not not retained by the claw of a frame is offset with respect to the claw of the other frame, so that the latter cannot raise the hook when it descends attached to the first frame.
  • D is called the spacing of the bars 11a, 11b of the racket
  • this dimension must be such that the arms are supported on the racket in their parts located above the bumps 4b, 5b so that this racket ensures stabilization while avoiding the tilting of the hook on the bottom board.
  • the distance Dl separating the top of the bumps 4b, 5b is such that the cooperation of the latter with the bars 11a, 11b causes the spouts 4a, 5a to be erased when the claws cross as illustrated in FIG. 27.
  • the distance d separating the lower part of the two branches 4, 5 must be such that the branch 5 is in abutment against the racket in the high position of the hook so as to allow the hooking of the spout 2a on the open pitch blade 14.
  • d is equal to D so that the two lower parts of the arms 4 and 5 cooperate with the two bars of the racket 11 in the high position of the hook.
