HAIR-FABRIC LOOM.

Specification of Letters Patent.

resented April '7, 190s.

rApplication led June 13, 1907. Seria1 No. 378,784.

To all whom it may concern:

Bef-it known that I, BRUNO KNrrrEL,l a sub'ect of the German Emperor, and residing at resden, German Emplre, have invented certain new and useful Improvements in Hair-Fabric Looms, of which the following is a s ecification.

yA invention' relates to improvements in looms for weaving so-called horse hair fabrics.

120 Accordingito my invention two nippers for catching the hairs are located atthe side of the shuttle and lextend forwardly in the direction of motion of the lay. The latter in making its regular, steady strokes advances i5 the nip ers to bundles of hair located at both sides o the loom, in front of the lay. One of the nippers seizes a Single hair, which is then shot into the shed on the passage of the shuttle. yThe jaws of the nippers are so formed 27o as to presentbetween them an inwardly nar-- rowing gap, at the back of which is the actual This mouth is so. small. that it can not nip more than asingle hair.` The nipper jaws are relatively long and ointed, so that they can readily enter the air bundle without' pressing the hairs together. The office of the narrowing gap is to conduct l.the hairs lying Within its province towardv the ni per mouth,

di Since the come to rest at exactly the same spot, it is obvious -that the nippers will take the. hair 't from different parts. of the bundle, which '35 must naturally be of suchwidth that the n1 persniay find hairs'pr'esented to them in g` "w at'ever pgsitionthey occupy. The nipper jaws may opened furthe urposeo seizing a hair eitherlrnerely throng the pressure lexi 4o' ented by ,their-"advance the bundle,`or by positive meegaan The reopening of the'nipers for releas'eo thescized han may be efected by aspring aetuatetlt stud, which as y the shuttle is thrown to and fro passes below 46 'an adjustable stop onl .the lay, which deu .presses it and. eauses itl to` actuate devices compel the 'nippersto yield up vthe air.A Y

l jInthe accompanying drawinl Figure 1 '50 is an elevation and part section o a fra ment L of a shuttle. constructed according to t is nvention. Fig. 2 is a cross section, and Fi i; 3 a horizontal section through the same. ig. 4 isa sectional plan showing the lay, fore 6.6 beam and hair bundles, the central portion being removed -to save space in the drawing. l

l1c which swings in a The shuttle 7) is furnished at the side withtwo nippers a. a (F 4) which pro'ect in the direction of motion of thelay m., t e shuttle being brought up to the bundles of horse hair at n n4 by the forward swing of the lay. Each of the ni pers has two limbs pivoted at c (Fig. 3). T e jaws a (the jaws al are-.precisely the-same) present between them a gap which gradually decreases in width in inward direction, while they only actually contact over quite a short distance, so that it 4is only ossible for a' single hair to be seized by t em-in this minute mouth. The jaws are closed by a s ring d, which forces a conically chamfered s iding sleeve c over the chamfered ends of the nipper Shanks. vThe jaws open against the action ofthe spring (1, on the advancing lay driving1 thel nippers into the bundle of hair, certain airs being at the same time gathered to ether by the Wedge shaped ni per gap. T at hair which has penetrated urthest into the gap will on the Mpressure being relieved (that is, on the lay cbmmencing its bakward swing) be seized by the closing nip er month.l lThe' nip-4 per jaws are reopene b shapedl stud f actuated b the spring When the head of the stu on the shutt e bein shot to and fro, passes below a stop 'h on-telay, a Wedge shaped projection on the shank of the stud, resses against a lever orizontal plane and presses upon a pint, against whose head the spring d abuts. rihe spring will be comressed butlat'the same time the pin l forced orward, so that the ni per mouth will 'sli htly open and release t e hair until now he d` by t e` jaws. The stud f1 for the nipf pers al 'is Athe twin of the stiidf. The vtwo studs, as isseen from Fig. 4, lie on'op osite sides of the shuttle axis, and their hea s are cut awa up to the latter, so that of the two 'stops h 1 furnished on the lay, the former, it,

Ialone depressss the stud f, and the latter, h1, alone de tresses the stud 71. The stops h't" can be a )usted at the back of the lay m, to suit the Width ofthe fabric.

Tn the passage of the shuttle only the rear nippers work; thus on the shuttle'be' shot y the verticalv rivet from left to right the nippers a acts, while on the shuttle passing from right to left the nip# pers a* is active. n n are the holders con tainin the bundles of horse hair, which 'are presse forward by spring controlled plates o o1. The holders are of such breadth that in whatever positionfthe shuttle may halt,

` the ers always lie within the provincenof the ho er aperture. The holders instead of position, the thenippers correspondingly. Supposing the t to e being secured in vertical position as shown in the drawin may be placed in horizontal orse hair being presented to shuttle to be shot from rig t: the stud f? n passing below the stop h1 will be depresse and will cause the nijlpers a to open and release the hair which it as just carried through the shed. Qn the lay m now swinging forward,Y the .nippers a will enter the hair in the holder it, a number of hairs small mouth, and the will be fed by the ni'p er gap toward the llatter will open and seize the foremost hair. On the shuttle bein l `n'ow'shot toward the right the nippers a w' carry* the seizedhair through the shed. Uponthe-stud f passing below the stop h, however, the nippers a will be reopened and the hair will be released. Hereu on the nip ers avrill seizeahair from the older fit1 y positive means if desired. suitable stops may be provided on the frame As alreadyl remarked, the nippers, for the purpose of seizing the hair, ma be opened n such case vjecting laterally beyond the sides of the shuttle, substantially as described.
