PATENT OFFICE.

In the mill shown in the accompanying drawing, the mechanical treatment of the fabric to be milled consists mainly of processing it by means of a hammer moving at high speed. The work process can easily be seen from the cross section of the machine shown in FIG. The fabric G goes in trains respectively. strand-like manner through the machine 'and is subject in the housing H to the Walk table E the impacts of the hammer A. In front of the housing H are the food and at the same time mill rolls JJ ^1, which the fabric is fed through a special insertion device K; the rollers J ² J ³ serve as outlet or as escapement rollers. The hammer A made of wood or metal, which is suspended between the ends of the spring B moved by the flywheel disc C , is guided in the slide rails D and its height can be adjusted so that the distance of its toothed lower surface from the base plate E can be regulated at will. The suspension of the hammer in the bow-shaped spring B enables it to make 200 to 300 blows per minute. In order to be able to give the hammer an oblique movement against the position of the waling table E , an arm X is attached to the former instead of the slide rail guide, the pivot point 0 of which can change the position in a sliding path Q of the side pieces A '; By this device, in addition to the fabric, depending on the greater or lesser inclination of the hammer movement, a more or less energetic friction is exerted on the fabric at the same time.

The whale table E, clad with wood, copper, etc., the surface of which is toothed or wave-shaped, is supported by the supports O and assumes a slightly inclined position, with the aim of ensuring that with every blow of the hammer, its lower surface is also beveled accordingly is to cause the tissue to advance.

The rollers JJ ¹ lying in front of the housing H , the length of which is equal to the width of the hammer, respectively. of the housing, stepped disks can be rotated at different speeds. The discharge rollers J ² J ³ are set up in such a way that they can serve as pull rollers or pinch rollers as desired. For this purpose the roller J ^{s is provided} with a belt pulley, which is operated from a pulley of the same size on the roller J. These two rollers therefore rotate at the same speed and the fabric is consequently stretched between the pairs of rollers in the housing H; If the rollers J ² J ³ are to function as pinch rollers, the belt is removed and the pressure roller J ^{2 is} more or less weighted; as a result, the movement of the tissue is delayed and a build-up of the same in the fulling chamber H is brought about.

The insertion device K attached in front of the rollers JJ ¹ is set in a reciprocating motion by the crank disk P by the linkage ^{mnn 1.} The stroke of this movement can be changed and by turning off the handlebar m the. Loading

movement can also be completely suspended. The rods separating the compartments of this introducer can be removed if necessary, so that the strands or strands of the fabric can be changed during flexing and brought into one or two or three compartments without that it would be necessary to remove the piece. Fig. 2 shows the manner in which the rods s s are held in place by pins g and tenons t so that they can be removed and reattached at will. The outlet roll L is used when a piece is only to be milled in a single pass. In this case, the piece z. B. beaten on four or five strands, d. H. If the length of the fabric is allowed to go through the machine in four or five turns, the first four strands fall to the bottom of the machine and the end of the fifth is picked up by the roller L and pulled out. This type of lay-up can only be used for very fast flexing fabrics. In Fig. 2 the course of the fabric is indicated by dotted lines when it passes through the machine, tied to three strands I, II, III. The setup of the machine described above now allows the different types of flexing to be achieved with ease: 1. In order to mill a fabric in width and a little in length, it is laid on one or more strands, so that it goes through the machine one or more times and all the strands are passed together through the central section k _{2 of} the insertion device . The stroke for the reciprocating movement of the latter is now regulated in such a way that the fabric is laid in a snake-like manner between the infeed rollers JJ ' and from these onto the milling table E in a horizontal plane - and then the blow of the hammer is given flat. By pulling the fabric back and forth and by the position of the same on the milling table in which it is hit by the hammer, the warp threads are preferably pressed together, so the piece flexes in width while it loses little in length . 2. To mill a fabric in length and little in width, the reciprocating movement of the insertion device K is suspended and the piece is inserted into three or six strands, one of which respectively. two runs through one of the departments ^ ₁ k ₂ k _s ; in this way, the tissue lies down, as it is no longer an-. is given, pulled back and forth, in the fulling chamber, in that it accumulates in front of the pinch rollers J ¹ J ³ , snake-like in a vertical plane. In this storage of the fabric, the weft threads are preferably pressed together by the material of the hammer, which means that the length is rolled in. 3. In order to flex both in one direction and in the other, the fabric is only brought into two entrances ^ _{1 %} ; these inputs receive a reciprocating motion with a half-stroke reduced; the tissue lies in oblique folds, so that it comes to lie obliquely under the hammer, whereby flexing occurs both in one direction and in the other. 4. In order to mill only in width, without losing anything of the length (even in order to lengthen the length), the fabric is laid in three or six strands, and the output rollers J * J ^S are set in motion so that they pull the tissue with them; in this way the same is stretched lengthways in the fulling chamber, and the warp threads are therefore pressed together; the piece therefore rolls in width and the blow of the hammer even stretches it out in length. The walke shown offers the advantage of a faster and more perfect work than the cylinder rolls and one more regular than the ordinary hammer rolls. You allowed both hard and very dense fulling, as is required for cloth goods, as well as to obtain a felted and supple milled product, as it is for light fabrics is appropriate. Since it can tumble without heat because of the slow movement of the fabric, it is perfectly suitable for treating novelties (nouveautos) in delicate and bleeding colors; it makes fewer creases than the other machines and can serve to complete the pieces started in other mills. The machine is also very suitable to replace the dryer rolls and machines for pulverizing the straw in the chemically cleaned fabrics. The fabric can, as explained, be folded vertically or horizontally, depending on whether the straw parts are in the warp or in the weft yarn. So you let the hammer work in the desired direction. Patent claims: At Hammerwalken: 1. the suspension of the hammer between the ends of an arcuate spring B attached to the crank; 2. the connection of the hammer by a linkage X with a correspondingly placed slide Q, whereby the position of the hammer in relation to the position of the whale table can be changed, zu.dem purposes, around next to the fabric at the same time depending on the greater or lesser obliqueness the hammer movement to be able to exert a more or less energetic friction on the tissue; the way of regulating the milling in width by using an insertion device K provided with several adjacent and interchangeable openings, which is arranged in front of the feed rollers JJ ¹ and which can be given a reciprocating movement as required the purpose of arranging the fabric on the milling table in such a way that the effect of the blow of the hammer takes place in the desired direction; ² / to blank 4. The device, which is arranged behind the milling chamber rolls J ³ both as a source as well as act as Hemmwalzen, indem- either of the lower roll a .zwangläufige movement of the same number of revolutions with the feed roller J or of the machine independent movement that is only dependent on the displacement of the fabric is given and in the latter case a pressure is exerted on the upper roller in a suitable manner.
