APPARATUS FOR WEAVING FABRICS.
Specification of Letters Patent.
Application filed August 21, 1913.
Patented Dec. 2, 1913. SerialNo. 785,833.
To all whom it may concern:
Be it known that I, EMIL PREIN, subject of the King of Prussia, and resident at Hanover,- in the Province ofHanover, Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Apparatus for WVeaving Fabrics, of which the following is a specification.
This invention relates to apparatus for the weaving of fabrics, in which the filaments all lie close to the yarn.
During the process of weaving, there are always filaments which spread out from the yarn, as is well known, even when they have been previously held fast or previously prepared, or when the weaving takes place in the moist state, and this especially happens with the filaments of the warp yarn in con sequence of the mutual friction of the fila-' ments during the forming of the shed and in consequence of'the up-and-down motion of the reed blade, and also with the filaments of the weft yarn in consequence of the suddenly occurring cessation of the adhesion of the filaments during the shooting and rapid running out of the yarn and also in consequence of the attraction between the material which is running out and that which remains behind. A portion ofthese filaments which are set free are bent, folded over and pressed down in the fabric by the motion of the reed during the throwing of the weft thread and owing to thethreads lying over it in the interwea ving. Thie filaments which still project from the fabric are subsequently removed by shearing and singeing machines in order to render the fabric suitable for its various purposes. But by this process not only are a number of filaments which possess a great power of resistance to breakage, lost for the fabric, but the interweaving of the filaments which project and the forcible removal of the projecting filaments have also very serious drawbacks. The objection ,to the shearing is that the very sharp knives operating at a great speed not only shear off the projecting filaments but also, any knots and threads which stick out and cut them clean away which is at first not noticed as damage and is only discovered on the application of tests for strength, whereupon one and the same fabric will give uneven results. With the singeing process, the repeated sudden heat makes all the woven filaments especially the unicellular cotton filaments brittle.
It is a great drawback moreover that the bent andfoldedinterwoven fibers are held in the fabric with their power of projection unweakened. If then at a later stage, the fabric is treated for some technical purpose, these filaments always again occur as points escaping out of the fabric, because their power of projection and the adhesive power of the preparation act against each other. Also, when the bent fibers are held during the drying under mechanical pressure, which as is well known is effected in various manners in technical weaving according to the application of the goods, they lie only restrained butnot cured. They hereafter also gradually free themselves from the bedding by reason of the various movements of the material, the alternative efiects of temperature and of unequal wear, whereby much damage are caused.
The object of the present invention is a mechanism, shown in various modifications, which is intended to obviate the above mentioned drawbacks. By means of this mech' anism, the warp threads are smoothed fiat immediately at the weaving point by a suit-- able means in the moist condition in such a way, that the projecting fibers are arranged lengthwise against the threads, and are woven into the fabric in this position. Moreover, it is of especial importance that the application of the fibers to the yarn should take place just there and at that moment when forces tending to release the fibers can no longer act upon the threads. As a suitable material for the moistening body, a rubber sponge is preferably made use of.
The invention comprises an arrangement whereby the support for the moistening body is attached to the loom shed so as to be capable of moving up and down and participate in its to-and-fro motion.
The device itself can be constructed in various forms.
In the accompanying drawing some of these forms are illustrated as follows Figure 1 shows an elevation of the first construction in combination with the adjacent parts of the loom. The drawing shows the frame of the moistening body and the mechanism for moving it just before the application of the moisteningbody. Fig. 2 shows the same device in the position after the application of the moistening body and during the moistening.
In all these figures, a indicates the lay sword, I) the lay, a the reed, d the breast plate of the loom. The warp threads are in i dicated by n and the finished fabric by 0.
The moistening body composed of spongy rubber or the like rests in a long liquid container e which extends over the entire width of the fabric and possesses above a slotfor the exit of the moistening body. The liquidcontainer 0 is removably attached to the .part b andswings with it to and fro. .By thearrangement of the moistening. body on the aforesaid part b there is efl'ecteda spe-: cially' favorable strokingaction and the pos-. H
sibility of the easy arrangement of the separate parts of the movement is assured. The} moving and guidance of the moistening body,v and its holder is effected by means of suit-, able rods and levers under the influence of the motion of the part I). At one end of the container is a tubular support 7" to which by, means of a tube the apparatus can be con-' 'nected to a filling receptacle.
In-the constructional form illustrated in Figs. 1 and 2, the containere is detac-hably secured to a bar g, which possesses ,projections'h in the neighborhood of each end, to
which projections, two pivoted unequally long levers a and lcengage, whereby the bar is connected to the loom. For effecting of The boss 7' is gages the lower plane of the warp substan-' tially at the fell. In consequence of the unequal lengths of sults on the raising of the moistening'body a short backward motion thereof in regard to the part I). The consequence of this is that on the simultaneous motion of the part b s the moistening body at the weaving point stands still for a short moment. This causes the moisture therefrom to penetrate more effectively in the warp threads and to moisten these completely. Hereby -a better laying down of the fibers on the threads is effected. According to the length of the adjustable boss rthe period of contact caIf be adjusted at will. As soon as the catch q has passed over the boss 1" it slides off it ,:and allows the limb 71 together with the bar.
the levers z and 70 there re-j 9 and the liquid container 6 with the moistening body to fall down. In order to hasten this rearward motion there is provided a spring 't. In order toprevent any lifting of thefabric on the engagement of the moisteningbody there is placed above the fabric throughout its whole length a lath a which is heldb-y the holders 4). The moistening of the completed fabric is prevented by a protectivexband-wawhich is stretched beneath the fabric close up to the fell, and is secured at both sides as well .asbehind ina suitable Having now described my invention and in whatmanner. thesame is to be used, what I claim and desire to secure, is-
1. The combination witha loom having a lay, of moisteningmeans, guided thereon, an-arm pivoted on the lay and having opera- .tive connection with said moistening means,
and astoponthe 100m frame to engage the said arm to cause the moistening means to be raised on thebackward movement of the i lay.
links being longer than the other, a moisteningdevice pivoted-to said links, an arm pivoted on. the bracketand having a pro- "jection engaging oneof the linksanda stop inthe path of the free end of said arm adapted to engage the armas the layoscillates and thereby oscillate .said. moistening device.
'3. In apparatus of the character described,
.a loom frame,..a boss adjustably' fixed on said frame, a catch-lever adapted to move oversaid boss, alug on said catch-lever,
an arm engaged by said lug, a moisture holder:engaged by said arm, a link con- ,necting'the lower part of .said moisture holder to a block, and .a-spring drawing said container downward 'whereby said moisture holder is reciprocated intoand out of contact with the threads at the weaving point.
4. ,In apparatus of the character described,
. and having a moistening body just below the weaving-point, a protective band to prevent contact of the -moistening body and the fabric.
5. Inapparatus of the-character described and having a ,moistening body, a bar disposed as acounter holder for the adjustment ofsaid moistening body.
Intestimony, whereof I have signed my name to,= this specification in the presence of two subscribing .witnesses.
