PATENT OFFICE.

In the process which is the subject of patent no. 28415 is, as long as the needles which the model apparatus has pushed up, should remain in their position, the relevant one The lock closed and both side jacks held in the catching position as soon as; but the needles should come into action, the relevant lock is opened and the trailing side lifter of the same up to the Tee down position.

With the device shown in the accompanying drawing, I achieve the same purpose by keeping the central triangle a 'and the small countersink bc retracted into the lock plate ρ as long as the raised needles are to remain inactive as soon as I want to operate them Let the middle triangle and the trailing triangle bc emerge from the lock plate.

The device which is used to automatically effect this regulation of the triangles α b and c according to a law corresponding to the commodity is shown in connection with the carriage S in the accompanying drawing.

The lock triangles α b and c are connected to the bolts s S ₁ S ₂ which go through the lock plate and which carry the rotatable bushings t ί _λ I ₂ provided with ratchet wheels r.

The bushings tt _x t ₂ have elevations and depressions at the top, on which the pins e of the bolts s S ₁ S ₂ rest alternately.

The bolt -R, which is horizontally slidable on the lock case, carries the two pawls kk _x , which are constantly pressed against the cogwheels r by springs, and is provided with the two noses η η , which, when the slide is moved, on both sides of the Machine-attached outriggers 0 O ₁ and thereby move the latch R.

The bushes tt _Y are rotated by one tooth by means of pushing on O ₁ , and by pushing on ο the bolt R is returned to its initial position, the springs V ₁ preventing the wheels r from falling. This game is repeated until the pins e fall into the recesses of the bushings t ij and allow the springs a _t b _x to bring the lock triangles α b into the working position. At the next stop at o, which takes place after another two sled tours, the lock triangles α and b are pulled back into the lock plate ρ by the inclined surfaces χ of the bushings 11 ₁ engaging the pins e.

The triangle c is moved by the pawl Ar ₂ , which is attached to the bolt T pulled down by the spring ν and is pushed forward with this when climbing the inclined surfaces of the angle gg _x at the end of each slide stroke. As soon as the recess of the bushing t ₂ comes under the pin e of the bolt S ₂ , the spring c · ¹ presses the bolt S ₂ down and the triangle c into the working position.

At the end of the next toboggan tour, the triangle c is pulled back into the lock plate ρ by an inclined surface χ filed on the sleeve I ₂ .

The ratchet wheels r in the present case have six teeth, and while the

Bushings tt _{x have} two depressions, the bushing t _{2 is} only provided with one.

The interaction between needles and locks is as follows:

While the carriage is to the right and the triangles abc sämmtlich in the Schlofsplatte withdrawn are the patterns needles are pushed by some pattern apparatus into the catching position in which they remain during the next four sledding. At the end of the fourth slide tour, in which the slide arrives again on the right, the pins e of the bolts 5 S ₁ fall into the recesses of the bushings t ΐ _λ , and the triangles α and b come into working position.

During the fifth toboggan tour that follows, all needles are pushed into the highest position by the central triangle α _{, the side lifter <f x} returns them to the catching position and the auxiliary triangle b returns them to the cut-off position. Towards the end of the fifth tour, therefore in the left position of the slide, the pin e of the bolt S ₂ falls into the recess of the sleeve t. ₂ , and the triangle c also comes into working position.

On the sixth tour (from left to right), all needles are pushed from triangle a into the highest position, from side lifter d into the catch position and from auxiliary triangle c into the knock-off position.

Towards the end of the sixth tour, the triangles α b and c are all withdrawn into the lock plate ρ.

The pattern apparatus then brings the pattern needles back into the catching position and the game repeats itself in the manner just described.

If one wants to switch off the lock regulation, one strikes back the rotatable bumpers ο O ₁ , Fig. 3, and pushes the angle g ₁ into the position dotted in Fig. 4.

The play between the needles and the thread, the working process, is the same as in the patent No. 28415.

There are also here in the front, provided with the lock device described Fontour only the needles that were pushed into the catch position by the sample apparatus, get the inlaid thread that so often forms handles on them as sled tours are made in which the pattern needles remain in the catch position, as these needles Do not work out any stitches during this time.

Only when the needles drop their handles and process them into stitches, the castle is brought into action by the central triangle and the trailing auxiliary triangle come into working position.

The triangle a is used to move the needles that the sample apparatus has left down from the lowest working position and the remaining needles from the catching position to the highest position, whereby all the handles on the needles get behind the needle tongues to allow all the needles to be pulled down to be able to drop into the lowest working position through the side lifters dd _x.

On the next tour, in which the triangle c is also in the working position, all the needles are removed from the. from the lowest to the highest and from there to the tee position.

When one the wheels r a different Zä'hnezahl gives, one can make the pattern more or less needles during sledging remain in the catching position and thereby more or less combine Henkel into a stitch.

This automatic lock regulation can also be used for other mesh formations by working the same on other knitting machines, e.g. B. at the No. 19510 in Germany patented, applied, whereby the most varied changes in the Let actuation mode of the needles achieve.
