COMBlNG-MACHINE FOR TEXTILE MATERIALS.

SI1?.(JIFIOA'.1IO1\I forming part of Letters Patent No. 620,747, dated March 7, 1899.:

Application filed February 25, 1898. Serial No. 671,627. (No model.)

To aZZ whom it may concern:

Be it known that I, EUGENE DELETTE, a citizen of the Republic of France, residing at Lure, Department of IIaute-Saone, France, have invented Improvements in Oombing- Machines for Textile Materials, (patented by Letters Patent of Addition No. 238,825, filed in France January 14, 1898; Letters Patent of Addition No. 110,266,filed in Belgium January 24, 1898; Letters Patent of Addition No. 81,432, filed in Germany January 29, 1898, and Letters Patent of Addition No. 18,852, filed in Spain January 29, 1898,) of which the following is a specification.

This invention relates to combing-machines for textile materials in which the combing of the sliver is effected by means of a stationary circular reed; and the same consists in a new kind of presser device, the purpose of which is to compel the material to be combed to en ter between the needles of the circular reed.

The application of a presser-cylinder to the combing-machines of the I-Ieilman'n type has been proposed heretofore. In that system the presser device is formed of a cylinder having a certain number of longitudinal and parallel corrugations or projections disposed in regular order on its periphery. This cylinder is movable about its axis and moved by a toothed pinion keyed onto its axis, which engages with a toothed wheel keyed on the axis of the circular reed, so that during the rotation of the same the projections of the cylinder arrive successively between the rows of needles of the circular reed after the manner of the teeth of two gear-wheels, but without any contact between said projections of the cylinder and said needles of the circular reed. In this arrangement the driving-cylinder is stationary with relation to the circular reed, with the result that after each combing of the sliver the circular reed shall move away from the jaws of the clamp with the presser-cylinder in order to release the head of the sliver and allow the same to be grasped by the pick-off device. This is obtained by imparting to the whole device formed by the circular reed and the presser-cylinder an alternately up-anddown motion. My device consists, on the contrary, in the use of a circular reed the axis of which is stationary, combined with a movable presser arranged in such a manner that the pressing of the material to be combed shall occur as close as possible to the jaws holding the sliver to be combed.

The invention will be described hereinafter in detail with reference to the annexed drawings, in which Figure 1 is a cross-section of the apparatus in a certain position. Fig. 2 is a cross-section thereof in another position. Fig. 3 is an end view. Figs. 4 and 5 show two peculiar arrangements of the presser-cylinder.

As shown in Figs. 1, 2, and 3, the circular reed M is of a small diameter and its axle is stationary in order to give more steadiness to that part of the apparatus. DriverA only acts on a portion of its periphery. This driver is movable on its axis and is carried at both ends by two supports B, arranged on two ends of the circular reed M and movable on the axis of said reed. These supports have an oscillatory movement on the axis of the said reed by means of -a pair of links which con? nect the said supports with levers E, keyed on the shaft G, the latter receiving an oscil latory movement from an arm II, also keyed on shaft G, (the keying of which may be regulated by means of a screw or key h, as more fully described hereinafter,) and terminated by a roller travelingon a cam P, arranged on the side of the frame of the machine. The reed M has a rotary continuous movement in the direction of the arrow at a uniform speed the jaw D of the gripper under the influence of the cam P, and the proportions of the pinions at and b are arranged in such a way that the projections of the driver engage between the rows of teeth of the circular reed toward the end of the combing when this driver has come into the proximity of the lower part of the jaw D. Then when this driver A has turned on itself to a sufficient extent to allow itsungrooved part to be precisely opposite the lower part of the jaw D the concave portion of the cam P imparts a slight brusk movement of recoil toward the said jaw, which has for its object to drive the materialbetween the teeth of the circular reed as near as possible to the jaw D and under the nose of said jaw. This position is shown in Fig. 1. It follows that said presser is eccentric. During the combing the driver A approaches the jaw D by a progressive motion. Then when it reaches such a position that the part without corrugations is opposite the jaw D the same receives a sudden receding motion toward said jaw. The presser A then falls simultaneously with the last rows of needles of the reed M and leaves the sliver-head free to rise at the moment the upper jaw D opens, and the blade F completes the rising of the head to present the same to the action of the pick-0K cylinders J, as represented in Fig. 2.

The presser Ais mounted on two supports 13, placed at the right and the left of the circular reed M, and it receives its oscillating motion about said reed through a pair of links 0, connecting the supports 13 with levers E, mounted on the shaft G, on which they are keyed. The shaft G receives its motion from an arm H, the keying of which may be regulated by the screw h, and which. arm termimates in a roll actuated by cam P on the side -of the frame.-

The rotary motion is transmitted to presser A by means of the gear-wheels a and b, one of which, Z), is keyed onto the shaft of reed M and the other onto the axis of presser A.

The pick-off is effected as in the systems of 'c0mbingmachines now in use through one or more finishing-combs I I and is produced either by means of an endless leather strip and two rollers J J or by means of a four-oscillating-roller system or by any other suitable device. It is evident, however, that the number and the form in profile of presser projections maybe varied according to the nature of the material to be combed.

In the arrangement shown in Figs. 1 and 2 I have represented as a specimen a presser provided with two juxtaposed longitudinal projections on the surface of said presser. It may, however, be advantageous to provide the presser with projections on the entire periphery thereof, taking care in such case to largely reduce the profile of some of the successive projections in order to enable the presser device to approach very near the jaw D. A device of this kind is represented in Fig. 4. Finally, in some casesfor instance, when dealing with very short wools-it will be sufficient to form the driver by means of a single projection, as represented in Fig. 5.

The screw h, by means of which the posisame as before it will move in a diiferent path or are of its circular oscillatory movement.

Having thus described my invention and pointed out the means whereby the same is to be carried into practice, what I claim is- 1.
