ROBERT LEMME in BERLIN. Machine for creating hat compartments.

Patented in the German Empire on August 24, 1890.

It is well known that hat compartments made of wool are formed in such a way that the fleece removed from the card is directed onto a core in the form of a double cone. The same is set in rotation by the card together with the fed fleece by means of two pairs of bearing cones which, in addition to rotating around their own axis, also rotate around a vertical axis, Fig. 3a, in order to guide the fleece in cross layers, Fig 3 a, to be able to act alternately on one and the other half of the core by hand. The hat compartments on the core are divided into two parts according to line xx, fig.

Now, with the current designs of the bearing cone drive, the disadvantage is that in order to produce the edge α, Fig and push rod releases until the edge has the desired thickness. The fleece then constantly runs onto one and the same zone of the core, and since as much material runs out on the smaller circumference as on the larger one, the position at the edge also becomes stronger and unevenly strong. The plates of the felting machine therefore do not come to full contact, press too hard in places, too weak in places, and an unevenly moderate fulling takes place; one obtains a strong head and weak edge α, while it should be the other way round.

Furthermore, there is the disadvantage that when the push rod is now disengaged, the cap rims are unevenly thick, because the vliefs does not lie in two equal halves to the left or right of the line xx due to wear of the pins and bearings.

The present friction interlocking on the drive of the bearing cone now enables the generation of slim tapering hat compartments towards the head to weaker from the cross section shown in Fig. 2a. Marked it is the same in that the reverse rotation which is transmitted to the bearing cone The push rod engages a friction-inhibited adjusting piece of the crank disc, so that only one material is required to turn the crank arm, as soon as the edge is to be formed, to reduce to the desired size during the walk.

The accompanying drawing shows such a drive in views and sections, FIG. 1 1 to 4, and an associated counter in Figs. 6 to 9. Figs. 10 to 12 show the position of the shaped cone in its carriers and the course of the Vliefses.

The shaft e is rotated from the card by means of cord c and stepped pulley d. This then transmits rotation to the vertical shaft /, which rotates the bearing cones h / i ¹ h " ² h ^{3 by} means of the wheels gg ^l g ¹ all in the directions of the arrows, Fig. 1. The core of the hat compartment together with the part that has been placed on it the light coming from the carding Vliefses ν then turns to the direction of the arrow, Fig. 1 and 3a to achieve with. to assist in Aufleiten of Vliefses intersecting layers, the bearing cone lead, besides rotating about its longitudinal axis at the same time a reciprocal rotation about the shaft on / off, for what purpose the arm I is grasped by the crank disk i by means of the push rod k , FIG. 5, which is seated on a sleeve m

Claims (2)

whose upper arm η find the shaft of the wheels g1g2 and the cone h hl h2 h3 bearing. By means of change gears ο the parallel shaft ρ is rotated by shaft e and the latter drives the crank disk i by means of wheel q. From this wheel q the crank disk i is now lifted in the current versions by means of the pedal, when one proceeds to the formation of the edge. Then the core of the hat only rotates about its longitudinal axis and the material runs up at the edge, Fig Worker tired. In the present embodiment, if the machine is to form the edge, the worker simply gives an impetus to the hat cone at the moment when the crank disk is at the dead point, or, with simultaneous use of the counting device described later, to the inducer ^, Fig. 7 Then the crank arm of the disk i is reduced without further ado to the size necessary for forming the edge, in that the engagement pin of the push rod k with the piece r guided in i and inhibited by friction moves more towards the center of the disk. The core of the hat now makes smaller turns than are usual when spinning the head b, and the edge area is also spun with cross layers, so that hat folds of the cross-section, Fig. 2a, are obtained. The adjusting piece r, which yields from the outside in the case of the material, but otherwise remains in place, is provided with side teeth. This engages in a spur gear s mounted on the crank disk g, which is held down by a screw by means of a curved woodruff spring s1, so that the necessary degree of friction can be achieved by tightening the spring s1 more or less. It goes without saying that the adjusting piece r could also be given the necessary frictional inhibition directly by means of elastic pressure and brought into connection with a counter, such as that shown in FIGS. 6 to 9 in view and sections. After the pressure on the inducer 13 has been pressed, this counter initiates the formation of the edge and carries it out automatically, so that one is not dependent on the worker for the latter. The counter shaft 2, FIG. 9, is driven by the cord disk or chain wheel 1 of shaft e by means of cord disk or chain wheel 3 and change gears 4. The worm of the shaft 2 turns the partially toothed wheel 5 of the shaft 6, which consists of two halves. Then the pin of the adjusting piece r, which is provided with a hammer, strikes against the arm 9 of the rod 8 with each rotation of the crank disk i, and the adjusting piece moves more and more towards the center of the disk until the sector 7 finally disengages, whereupon the rod 8 returns to the starting position by weight 10 or the like. The formation of the edge thus initiated continues as long as the toothed part of the wheel 5 engages in the worm of the shaft 2. The arm 11 of the shaft 6 must be set so that it hits the release arm 1 2 at the same time, which can be made noticeable by a signal from the worker. Now the remaining Vliefs is used for further spinning of the head by adjusting the crank arm of the disc accordingly. If the arm 11 is then released again by material on the inducer 13 and the arm 12, the gearwheel 5 also falls into the worm of the shaft 2 in the direction of the arrow, Fig. 9, the formation of the edge then begins anew, etc. To regulate this activity If the arm 11 is expediently provided with a set screw and the wheel 5 is made from two parts which can be adjusted by means of an arcuate slot and screw, Fig. 7, in order to be able to change the number of effective teeth of the same. Patent claims: 1. A machine for the production of hat compartments, in which a proper edge formation is brought about by the fact that the oscillation amplitude of the shaped cone is gradually shortened, and for this purpose the connecting rod with its crank disk which produces the oscillating movements of the same by means of friction in the latter held inhibitor fr) is connected, which experiences a radial displacement by Anstof. 2. A machine of the under. 1. designated type, provided that in the same the displacement of the said arresting piece Ir) is brought about automatically by an adjustable counter (5, 7, 8, 11) which adjusts a stop (9) in such a way that the arresting piece through with each rotation this stop is shifted a little radially inward.
