The invention consists in improvements to certain parts of the machine for which an English Patent, No. 2610, dated October 1st, 1870, as well as a French, No. 95910, dated July 4, 1872, and an Alsafs-Lorraine, no. 38, dated July 20, 1872, was granted as a result These improvements make the machine much simpler and easier to adjust and operate with greater certainty.

This result is achieved by replacing the previously used chains or belts without Ends reached by cylinders with helical elevations, which the latter from the Center to both ends run in opposite directions, while the one cylinder, or the pair of cylinders taking its place is carried in a frame in such a way that it swing around the center during its rotational movement and stop as a result can be parallel with the other cylinder or cylinder pairs.

The oscillating frame, the shape of which depends on that of the oscillating roller, carries on its ends bear the bearings for the cylinder, while the frame itself on each side is supported by a pin lying in a bearing, so that the axis of rotation of the frame forms a right angle with that of the cylinder. The frame is also on each side by means of an angle lever in connection with the regulator, which was described in my earlier Pateriten, and depending on the same moves, removes or approaches one or the other side of the oscillating cylinder from or to the fixed cylinder, and the pull which the screw threads, which always run downwards, on the Exercise machined material is thus reinforced on the one hand and. on the other hand reduced, the work piece thereby brought back in its central direction, and the The parallelism between the screw cylinder and the RegulaFor was restored.

The drawing gives an example of a machine with a pair of screw cylinders, which take the place of the two pairs of chains previously used. The same is done on wooden sleepers shown fixed. Like letters denote like parts. Fig. 1 is a basic plan, _ FIG. 2 is a view and FIG. 3 is a cross section of a machine. Fig. 4 shows a part of the rocking cylinder and the frame on a larger scale. Fig. 5 shows a profile of the cylinder jacket with screw threads on an even larger scale.

6 to 9 show the regulator and its connecting pieces in longitudinal section, two Floor plans and a cross-section on the same scale as Fig. 4, and Fig. 10 shows one Cross-section of the regulator covered with the middle rod.

R and R 'are the cylinders or rollers with screw threads on their jacket, called screw cylinders. R is the movable or floating cylinder, carried in the frame SS ¹ and S ² , undi? ¹ the fixed cylinder; both rotate against each other. M is the processed material or work piece, which is pulled through by the rollers B and B ^1; B carries the pulley P, and by means of P * and P ² sets the shaft D in motion, which in turn serves to set the two screw cylinders in motion. This happens from the center on the oscillating cylinder, by means of the gears W and W ¹ , from the end on the fixed, by means of the pulleys P ³ and P *. In all cases, however, gears can be used instead of the pulleys and pulleys instead of the latter. G denotes the regulator, between whose rods bb ¹ and b ² the work piece M passes and which can be rotated around the support pin C in the middle. Due to the friction caused on the rods bb ⁱ and b ² , a certain tension is exerted on the regulator in the direction of movement of the workpiece M. If the pull is the same on both halves of the regulator, it will not change its position; but if the work piece goes to one side or the other, it pulls the regulator on that side with it. The movement is transmitted by means of the pin E and the levers L and L 'to the rod S of the oscillating frame SS ¹ S * , so that the oscillating cylinder moves away from the fixed cylinder on this side, while it approaches it at the other end. As a result, the work piece is tightened more strongly on this side by the screw cylinders and less strongly on that side, until it reaches the center again and the regulator and cylinder return to their normal position. The swing frame SS ¹ and S ² consists of the side

pieces S, the pins S1 of which rotate in bearings, and the ends S2, which carry the bearings of the cylinder. The frame is shown here constructed of tubes, but it can also be made in any way in Gufs, or by any other known method. F and F1 are parts of the machine frame, T the support beams. Fig. 5 shows how the screw threads can be produced from bent copper strips on the jacket of cylinders. This construction, too, can be changed at will; the cylinders can be solid rollers or manufactured in some other convenient way. These machines can also be made with two pairs of screw cylinders, each of which replaces a pair of chains, or the machine can be changed at will, both in its parts and its proportions, as well as in its general system, and does not conform to the given , details required for description. Patent claims: The invention consists in the following points: 1. The application of rotating helical surfaces in addition to their rotational motion can assume an oscillating or swinging movement for the sake of opening and conduction of work pieces such as fabrics etc. 2. The control of the oscillating motion of these helical surfaces by a regulator. '. ' 3. The swing frame for suspending the wing cylinder. 1 sheet of drawings.
