CHENlLLE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 650,641, dated May 29, 1900.

Application filed July 29, 1899. Serial No. 725,464. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK HENRY GELDERMANN, a citizen of the United States, residing in Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Chenille-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to machines for producing pile fabrics, and it has reference particularly to machines of this nature used for making that especial kind of such fabrics generally known as chenille.

The improvement in which the invention consists resides in the novel construction of a certain means whereby the threads for producing the pile of the chenille are directed and wound onto one of the threads which constitute its core or warp. I

The object of the invention is to so construct the means referred to as to materially improve the quality of the chenille produced, especially where the latter is produced in several colors, and it is the desire to keep said colors perfectly distinct and unblended in the finished article.

The invention is fully illustrated in the accompanying drawings, wherein- Figure 1 is a top plan view of a portion of a chenille-machine, enough thereof being shown to clearly illustrate the nature of my invention. Fig. 2 is a perspective view of that part of the machine which my invention directly involves. Fig. 3 is a transverse sectional view of what is shown in Fig. 2,certain parts being removed; and Fig. 4 is a sectional View of a modified form of my invention.

In order to clearly set forth the nature of the invention, I will briefly describe that form of chenille-machine to which I propose by preference to apply it and which is shown in Fig. 1.

The frame of this machine is designated by the reference-letter a, and above the same there is journaled in a bearing a, that exin any suitable manner, so as to insure their properly passing over that pair of pulleys c which they are approaching.

The cylinder 1) is provided with one or more circumferential grooves (Z, any one of which is adapted to receive a'driving band or belt for rotating said cylinder. About midway its length said cylinder carries a disk 61, which is rigidly secured thereto and revolves therewith and which carries in suitable brackets e bobbins e, which bobbins supply the thread for forming the loops or pile of the chenille.

fis an annular shoulder that is carried by the cylinder, near the end thereof, adjacent the rolls 0, and from the said end of the cylinder extends forwardly a pair of thread guides f, which are elastic and whose free ends tend to approach each other in the line of the bore of the cylinder.

From suitable bobbinsfnot shown) and extending over pulleys g are the warp-threads g, these threads beingv guided between certain of the wires. It should be here remarked that as they pass through the cylinders and between the rollsc the wires assume positions which in cross-section correspond to those of the four corners of a rectangle having its top and under sides horizontally disposed and that the warp-threads 9" (there being two of them) are guided the one between the upper and lower right-hand wires and the other between the upper and lower left-hand wires. The threads 9 after passing through the cylinder extend through the thread-guides f and thence back again between the wires, and it is at this point that the threads extending off the bobbins e are spun around the-series of wires and threads g by the action of the rotating disk 61. The threads passing off the bobbins e are designated by the referenceletter h, and they extend over a guide-ringt before being wound or spun, as above inentioned and as designated at c", said ring being carried by arms j, that extend forwardly from the shoulder f, being secured therein about the cylinder by means of adjustingscrews j. Between the rolls 0 the portions of the threads h which are wound about the wires and threads g are being continually cut by an inclined knife 7c, that is adjustably mounted in a standard 70', mounted on the frame and disposed on the side of the roll 0 opposite to that to which the threads approach. As fast as the short strands that are to form the pile of the fabric are thus produced by the action of the knife each of the threads 9 (which threads now divide, respectively passing through suitable eyelets Z) and another c'oacting thread m are twisted together by any suitable mechanism (not shown) that also acts to draw the finished chenille away from the machine proper. The threads m are fed from any suitable source over pulleys m, that are journaled in a bracket '11, that extends from the frame a, and they pass back from said pulleys around the rolls a and then ce between the same, from which point they begin to be twisted with the threads 9. Now I have ascertained that owing to the fact that the ring '5 affords no positive means for feeding or laying the several pile-threads onto the wires one after another or side by side, as it were, said threads tend to overlap their own convolutions, as well as those of the others. This action produces chenille which is uneven and otherwise poor in quality, and it is all the more perceptible where several colors are used, for here the colors are blended more or less and are not kept distinct from each other, as they are intended to be. In order to oh- 7 viate this difficulty, I have provided a ring of such construction that the threads 71. are laid or wound smoothly and uniformly about the wires 1), as strands of a band, as it were, which may be transversely colored as said strands are colored.

The preferred form of my improved ring is clearly shown in Figs. 2 and 3. In its body portion 0 is mounted a series of inwardlyprojecting eyelets constituting thread-feeds or thread-guides. Each of these eyelets preferably consists of a wire loop 19, the same being adjustably maintained in the body portion 0 of the ring, in which its ends are set in orifices 13, provided for the purpose, by means of set-screws q. These eyelets may therefore be adjusted radially in the ring. Their inner ends are bent outwardly-that is to say, away from the cylinder b-when the ring is mounted in position in the machine. They do not all project the same distance; but they are situated in a successively-advanced disposition. All, however, project inwardly toward the wires close enough so that the distancebetween them and the wires is reduced to a minimum, and consequently the thread is by them wound true on the Wires. It should be remarked that the loops should be of wire that is pliable enough so that it may be bent with readiness into any desired position.

In the modification of my invention shown in Fig. 4 instead of the wire eyelets p I employ as thread feeds or guides small tubes 3, the same penetrating the body portion of the ring obliquely and being adj ustably secured in position by means of set-screws s. It will be seen that by adjusting these tubes they may be brought in more or less proximity to the wires or be made to assume a more or less successively advanced disposition.

I do not wish to be confined to either'of the particular forms of rings hereinbefore described, for I deem any means which feeds the threads onto the wires in successivelyadvanced disposition or which in addition thereto feeds the threads onto the wires at points appreciably contiguous thereto within the scope of my invention.

It will be seen that by providing a guidingring so constructed that the pile or loop forming threads can be fed onto the wires from points in close proximity thereto is obviated that possibility of overlapping the threads which is due in some degree to the fact that the line of winding does not constantly and perfectly coincide with the axis of rotationof the ring, the latter at times slightly, though unavoidably, changing its position. 7

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a chenille-machine, the combination, of a ring for winding or laying in convolutions the pile-forming threads, and radially-disposed and longitudinally-adjustable thread-feeding devices carried thereby, said thread-feeding devices extending in contiguity to the axial line of the ring, and being arranged in successively-advanced disposition, substantially as described.

2. In a chenille-machine, the combination of a ring. for winding or laying in convolutions the pile-forming threads, radially-disposed a'nd longitudinally-movable wire loops carried thereby, and securing'means for said loops also carried by said ring.

In testimony that I claim the foregoing I have hereunto set my hand this 21st day of July, 1899.

FREDERICK HENRY G ELDERMANN.
