DIVISION A.

To ail whom it? may concern:

Be it known that I, J OHN OLUTE, 0f Cohoes, county ofAlhan y, and State of New York, have inventcd a ncwand uscf'ul Improvement; in Mat-hincs for Uniting; Knit Fabrics, of which tlufollowing; is a full, clcar, and exact dcscriptinn, rct'ert-ncc living had to thc nccompauyiug drawings, making part of this specification.

My invcntinn rclatcs to certain ilnpl'0\'0- nLcnts in that class of t'urning-oti'machincs dc- Stl'llNtl in Lcttcrs Pat'cnt No. 228,802, dated June 15, 1880, and known as circu1ai"turning-ott' machincs, uscd in swing togcthcr the t wu scl vagc or looped edges of knit-ted 0r loopctl fabrics, in which machines the. points carrying-111v edges of the fabric are arranged in a virclc and project iadially from a revolving cylimlcr, so called, of suitable t'orm and construt-tion. and providcd with suitable applianccsfor carrying the points and bringing and lmlding thcm succnssivcly nndcr, the nccdlc whilc a singlcur double stitchis i'ormcd. In machincs at this class, known as doublestitch cyli ndcr turning-nit machints, a sihglc stitch is madc in the usual Hllklllltl], and thc cylinder. rcmains statinnary until a second stitch is formcd ulmvctheothcr, thctwo stitch- (as constituting what iscallcd a tinuhlcstit-ch. Attcr a dnuhlc stitch is thus tnrnicd thc cylin- (10! moving brings the next point under the Il((dl(, whcn anothcr double stitch is tinned and an clnsticscnm is thus product-d. In forming thc svvondstitch-411st is tosay, thcsccnnd art of n dnuhlc stitch-41w nccdic audloopcr lay snitahlc nn-chnnisin nrc raised above thc falrrit'S high cnuugh tn nlluwthc nccdlcto pass over the fabrics at thc tinic whcn it would otlrcrwista lltl\'t passcd again through the sclvagc ur ltmpttl mtg-cs. and tinswnnd part of the doulilv stilt-h is complctnd whiic tlunccdlcand lnupcr :lrv abovc thc nitric-s.

My invcntiun consists of n doublv stitch t-ylimlcrturning-01fmachine in which the nec- (4' and thc Iunpcr arc raiscd and inwcred silnnpcr lmldcr lever, suitably (Ollllttittl with ttll'il nthcr and nim'czi hya can: on tin-'connt rshaft.

My invcntinu furtin-iconsists nt' curtain dctails of construction hcreiuaf E3 tinsel-innit, pointed out in the claims.

In the accompanying drawings, Fig-urn l is a side elevation of my invcntien with certain, details omitted. Fig. 2 is a pizza ViOW oi" the samc. Fig. 3 is a side elevation ofthnnecdlc- 5 arm lcvcr, the lunpcrholder invcr, and thc connecting-rod. Figs. 4 and 5 rnprcscnt the (-0unt-cr-shaft, cam, and cant-blank; Fig. 6, thn t-rip-hwcr cam, roller, and spring, and a part; of the trip lever; Fig. 7, the iuopcr-holticr and spring, the cud of the loopcr-holdcrlcvcr, and the; connecting bolt; or stud; Fig. 8, thc cain-fiistcning and details.

A is the supporting frame or stand, which may he of any suitable form for carrying the parallel axlcs B and G, and thc projecting arm D.

In the drawings, the axlc B is the needle and looper-cam axlc, which projects beyond the frame, and in practicc carries tin driviug-puL lcy and shipping devices.

E is a lug to carry the SliipPtEf-lQVtl.

The shippingdcviccs and the driving-pullcy arc not shown in the drawings.

The axle G is the counter-shaft, is parallcl t0 axle B, and is driven by the spur-whccls F and G at onc'halt'the spccd 0t axlc B.

Attics B and L- rcvolvn in suitable hcarings in uprights H, l', J, and K.

By means of scrnws through tinscrcwdmlcs 8o L, the frame orstand A may 'Eic Sttlitfiti to thc top of atn-nch or table, near its cdgc, in such a manncror positinnthat thc cyiindcr wiil projcct laterally thci'cfrmn.

Thc outer or overhanging" .rud of arm D is pmvidcdwitli a huh, N, hurt-d to rct'cii'n thc cylinder-axle in this nsnztl manna-r.

The cyiinder is net; shown in the drawings, becauss the construction of such cylinders is tan well known to require tlcscription here, 9.0 and the parts of a cylinder nenessaryto a desuription of my invention are sufficiently indicated in. Figs. 1 and Tits syiinder may be at any suitabie form cnnstruction fer carrying the points U and ntiugi them successive! info theif prnpcr mus belnw tins :issdie,

is a ring", nsuaiiy if brass, into which the 55 block r fits loosely in the cam-groove s of cam on the pinion and on the ratchet-wheel, thatv the latter in moving one tooth will move thecylinder enough to carry the points therdistance required for each double stitch, or for .each single stitch, when the machine is used for making a single-stitch seam.

U is the fulcrum-post usually employed in connection with the eccentric or. pawl rod 'V and eccentric W for working the ratchet-wheel T. The eccentric \V is carried by the axle B.

The trip-lever X has its fulcrum in a stud or pin, Y, projecting from the arm 1). One end of the trip-lever X is provided with a friction-roller, Z, which rests on the trip-lever cam a and receives its motion therefrom. The trip-lever cam in its cylindrical part .is concentric with the eonntershaft (I, and the other end. of level X is so curved that the bearingpinb does not interfere with the action of the pawl-rod V while the roller Z rests upon the cylindrical port of cam a. The cam u is fiattened on a part of its face, as shown in Fig. 6, in such manner that when the roller Z rests upon the flattened part the pawl V will be lifted, and, resting upon pin 1), cannot move the ratchet.

\Vhen the machine is in operation, forming a double-stitch scam, the parts are so adj usted that the pawl-rod V will he raised in time to prevent the movement of the ratchet while the second part of the double stitch is made.

'c is the needle-cam,and d is theloo'per-eam. Both are of the usual for|n, are carried by the axle B, and operate in the'nsual manner.

A cam-block (not visible in the drawings) moves in the cam-groove of cam c and receives the pin 0 of the needle-arm f.

g is the looper-holder.

h is the needle. and i the looper.

The stud j of the needle-arm is attached to one end of the needle-arm lever l.-. The stud lot the looper-holder is attached to one end of the looper-holder lever m. The other end of the lever m is connected with a stud, 0, on the lever I.-, by a connectingrod, p. The end of lever I; nearest the stud 0 is provided with a pin, 1 inserted in a cam-block, 1'. The camt on the counter-shait (I. The cam 18 may have either a groove, 8, as shown in the drawings,

or the end of lever k may be provided with a friction-rollerland a suitable weight or spring, to hold it down on the face of the cam in a manner similar to that shown in Fig. 6.

The form of cam t (clearly shown in the drawings) is such that each revolution of the counter-shaft will once raise and once lower the cam end of the lever k, and thereby raise to form the second part 'of a double stitch.

and lower simultaneously the needle and looper when properly connected with or attached to that lever.

The several parts must be so proportioned and adjusted that the needle andlooper will be lowered to form a single stitch-that is to 'say, the first part of a double stitch--and raise-d \Vhen a single-stitch scam is to be made, the spur-wheel (l is moved along the counter-shaft C and thrown out of gear with wheel F, and said counter-shaft and cam t thereon fixed in such position that thccam-block r will be held at its highest point, thus allowing the needle and looper to remain at their lowest working limit. The cam a on said counter-shaft. which is now fixed and inoperative, is also adjusted and fixed in such position and relation to the roller 75 on the trip-leverX. that said roller and tbat'end of the lever will be elevated and the other end of the trip-lever depressed col"- respondingly, this allowing the pawl-arm V to always engage and drive the ratchet-wheel T. Thus it will be seen that the axle (l, eccentrics t and a, and the trip-lcver X will all he inoperative and at rest, and the pawl-arm V will operate the wheel T at each revolution of the axle 1;, and thereby cause a single row of 5 stitches to be formed.

r is the looper-holder spring, (SPO Fig. 1,) and a is the spring (see Fig. 6) for holding the trip-lever roller Z against the fan-e of the cam. The lever I; has its fulcrum on a stud, 1:, projecting over the needle-can], and the lever n! has its fulcrum on the stud :r, on the opposite side of the upright column K. The stud a: is shown in dotted lines in Fig. l.

\Vhen it is desirable to form a double-stitch seam without raising the needle and looper above the fabrics in forming the second part of the double stitch, the set-screwy is loosened or taken out. so as to allow the cam tto revolve freely on the counter-shaft,'aud the cam is turned on the shaft until the needle and looper are brought into their lowest positions, and until the fastening-pin .2, passing through the column J, will nter the hole 1' of the cam and fix said cam to column J so that it cannot rotate. It will thus be seen that since the ram i cannot rotate the needle and looper will not be raised, and will always operate in the same plane. The cam a will, however, still not upon the'trip-lever and cause it to lift the pan-harm V, for the purpose of allowing the ring to re-' main stationary until the second stitch is formed.

2 and It are suitable collars to prevent the cam t from moving endwise on the countershaft. I

Having thus described my invention, what is claimed in this division of the application 1. In a machine for uniting knit fabrics, in which the needle and looper are adapted to be arnrlever k and the looper-holdcr lover in,

needle-arm lever k and the looper-holder lever- 111, having a link-connection with each other, in combination with a earn,- t, for operating the 20 needle-arm lever and looper-holder lever, ar

ranged on a'counter-shaft, (1, parallel with the v needle-cam axle B, and driven by spur-wheels F and G at one-half the speed of that axle, sub

. stantially as described..

' 4'.' In a machine for uniting knit fabrics, in

'which the needle and looperare adapted to be raised and lowered simultaneously, the needle-arm lever k, the .looper-holder lever m,

connected with each other, as described, a cam,

t, on thecounter-shaft C, for actuating said levers k and m, and means, substantially as described, for fastening and loosening the cam t on the counter-shaft,-and forholding the-cam 1 stationary while the counter-shaft revolves,

substantially as described.

In testimony whereof I hav e hereunto set my JOHN GLUTE.
