IMPRm/EMENT IN PowEa-LooMs FoR-.wEAviNG HAIR-CLOTH.

Specication forniing part of Letters Patent No. 421S0k8, dated OctoberAQ, 1864 antedatcd sp'rn as, 1sc4.' l

To all whom it may concern.'

Pawtucket, in the county of Prbvideiiceaand ,State cfIiRhode Island, have invented a. new and nseflimprovemenoin power looms for weaving hair-cloth.and fabrics' in which the weft is composed of separate lengths `of material'instead of being continuons; and I do hereby declare that the following,-` is a full, clear, and exact description of the same, refer ence being had tothe 'accompanying drawings,

` makingypartof this specification, in which- Figure l is afront elevation of the machine wlii'chexnbodies my improvement. Fig. 2 is a 'side elevation of the same. -Fig. 3 is a rear elevation of the same, -croi' the reverse end from thatshown in Fig. 1." -;.`Eig. 4 is a plan of the ',machine. Fig' 5 is einigte of ade-tacked por Vtion of Fig. el, -illustrat'iire of the-peculiar mode of operation hereinafter described. Fig. 6 is a rear elevation of 'the said machine arranged Fig.

the loom in a dierent position relatively from that ofFig. 6, thetwo figures illustrating'the peculiar mode of operation hereinafter described -as produced by the he'a'ting'move-A w ments ofthe lathe.

Similar letters' of reference,irnlicntecorre rspendi-ng parts'in all the ures.

The apparatus representedin the said draw'- ings i's a modified construction ofthe appara. tus for feeding or serving the weft to' haircloth looms which is shown and described. in Letters Patent of the United States nu'ln'l her Low-32,634, bearing date J une 25,' 41861.

'The Vtirst feature of my improvement relates to the construction of `the repeating mechanism or means by which, in case that the selectt in g-instrnnient fails to select a hair or weft 'at its rst e'ort, the operationwill be repeated several times during `a single beat: .of the lathe. In the patent-before mentioned the detect or stop by which the opera-tion of the selecting device was arrested when 'a weft was selected Was controlled by the Aposition of the pad (so called,) the movement of which depended upon the seizure of faweit by the selectin ginstrnment, the pad in that instance 4performing the double pur-pose' of Aholding' the.

weft in the notch ofthe lance71orselectinginstrumenthand also of `controlling the stop I; before mentioned. .By my present improve- Be it known that, I, ISAAC LINDsL-EY, of

'ment these functions are separated; and this -part ofmy invention consists in controlling vthe operation of' the stop by means of a deli .cate linger or detector that has a movement' lacross the position of the selected weft after each operation of the selecting instr'nmenthe tween the same andthe mass-of weft when the weft is notpresent, or is arrested by thel weft when itis present. By the first-named condition-the stop is placed so as to be inoperative, and per'inits,t.he operation of the of my invention consists in lthe employment,

in "connection with thevselecting mechanism,

of a second detent or stop, which arrests the: selecting mechanism in a position to be out of the Way .of the nipper, and is brought into vaction with each backward movcme t ci the lathe in case that the weft fails to be selecte/d, and continues in action during anydetermined number of picks, andv is then automatically released.

To enable others skilled in the art to make and use my said invention, Ixwill proceed to describe the construction and operation of 4the saine.

' `In the drawings, A is the bed-plate of the apparatus, which is designed to lie-'firmly `secured to the metal plate B, (shown in dotted lines,) extending from the left endet' the race- 'bca-m G of the lathe. AGis an upright stand on -the bed-plate A, in the upper part of which is formed suitable bearings for the driving shaft c. lIn the front ci" the stand C is fitteda slide, ol, which is connected by the rodf to] a stud or crank-pin in the face-of the wheel f,

Figs. l and 2, on the drivingLshaft'aJhe re elution of which is thus made to reciprocct the 'slide d vertically. The lance or selecting instrument k is scoured in'thev lower part of the slide d by means of a binder,"t, with set*-4 screws or otherwise, and the downward movement of the slide plunges the selecting device into the-mass'of hair or weft-,which is held in a`` suitable receptacle, e e, beneath it, in .doing which one of the hairs or wei'ts is .caught-'by the selecting-instrument andfwitlrthe upward.

movement of the slide is deiiected. from the t mass and'hcld in the proper position, :iside `from it, as shown in Ifignl, to 'beseiz'ed 4by the nipper bet/Weenthe-selecting-instrument' and the mas's'andl drawn into the open shed.

The padfi,vinvvthis improvedjconstruction,

'. consists ol? asurlaceupon the lower pait'of la' t sliding sleeve, y, which inclosestheshank of the selectinginstrument:4 in a kind: of sheath, f from which it protrudes to catch-ahai-r orweft' i vfrom the mass'fby the movement-'above mcntioned, and bythe reaction of the spiral spring .7'3, or an equivalent yielding lforce, caused by the upward moven 'e it; vof lthe slide d, is-drawn tinto thesaidsheath, 'carrying the hairorwei'tso-selected against 4the pad i onl the sleeve, which forms a bightintle weft and holds the i same-in 'the cnstod y ofthe selectin g-instrment ;until it is seized and disengaged therefrom by ithenippvx-,fto be drawn into the open shed. l The operationofthe selecting device is ar irestcd and it is heldin its proper position aside from the mass offweft when a. weft' has been if-'selected' vby means of a. datent ors'top, h, at

pivotfa, connected with the sleeve y,'or other- :wise nrrangedto -move across'the position of i the selected'n-e-f't, and having. a'iingenc, or Y F' an" equivalent device to communicate motion Ito the connecting rod j, and thence to the pawl bj, and a'ithird finger, tl,- wh-ich slides upon a .'-stationary inclined snrfaceym,v conveniently to select a weftri'rognv the mass, the comes in eontaclw'itihgtejinclined surface m, .and by'sliding thereon f sings the detector 's beneathand to one side of the selecting-mvstrnmentr,'the-[same increment'. swinging the linger o directly beneath the projecting piece -igonthc lower end of' the connecting-rod j, and when .the 'selectingLinsti-ument asccnds .after'bein'giplunged intotheinass oi weit, and

one ofthe hairs'o'r wefts. is selected and del fl'ected, 'tliercfron1`, jthe spiralgsln-ing I-onthe .pivote swings the dctectorsback to its former 4 position, in doing whichV i't 'is'arrested by 'the presence' of .the selected weft, and, resting` with which vitcomes in contact. and lifts, and vwith itthe rod j, the upper end ofl the latter `serving toiswing vthev pawl b into engagement with-the stop hon the wheel P andarresting its revolution=with the selected weft' sufficiently deilected'to-be seized by the nippel' between the" selectingLinstrument and the mass'. Should the selecting-instrument, h ow-.I everf,v.fail v"to, select. a: weft' fromthe mass, the' absenceof the deflected weft permits the de tector 'to swing across the position `it, would otherwise occupy, and its linger rv t'o swing vvfrom beneath the projection j of' the connect'- ingfrod j, which, with the pawl b,'rema1ns nnmoved during the ascending movement ot'4 the z slide d, and no engagement of the pawl b with the stop' h takes place, and the'whecljP there:l fore continues. to revolveand repeat the op-A eration of the selecting-instrument one or more ytimes until -a' weft' 'is selected, when the. operation is arrested, 4asbei'ore explained.-
