IMPROVEMENT yIn MAcHINEs Fon sEwiNe GLOVES.

Specification forming part of Letters Patent No. 188,616, dted-Maroh20, 1877 -application filed To ail whom .it may concern.:

Be it known that I, HANS P nTnsHnNRIK- B'EN ,of Copenhagen, Denmark, and a resident of Brooklyn, New York, have invented certain new and useful Improvements in Glove-Sewing Machines, of which the following is a specification:

The object of 4my invention is to ,prodnce a glove-sewing machine by which every seam required on a glove can be sewed perfectlyand conveniently, with either a straight or a zigzag seam, and by lock-stitch.

The invention consists in the construction and combination of the various parts, as will be hereinafter described, with reference to the accompanying drawings, in which- .On Sheet 1, Figure l is a front elevation, partly in section, of a glove-sewing machine constructed according to 4my present inven-. tion.y 0n Sheet 2, Fig. 2 is-a perspective view, partly in section, through the line a: :v of Fig. 1, taken from the side where theoperator sits, or in the'direction 'indicated by the arrow 1l on Sheet 1. Fig'. 3 is a detail section (through.

the line y y of Fi 1) of the presser-foot and feeder, and the p atel to which it is attached.

Figs. 4 and `5 are detail sections (through the line z z oi' Fig.,l) of the needle-bar and crankpin, showing the diierent positions ofy the same, and ot' the'ratchet and shift wheel to produce a straight and zigzag seam.'4 F`1g.6`v

is a detail ofa section of a ratchet and' of the pawl and cam lever for operating the same; 0n Sheet 3, Fig. 7 is a detail. section through the line fn o of Fig. 2, seen 4in thedirection of arrow 2, showing the reverse or inside of the side plate with the movements for :operating the needle, feed, and presser, foot.. Fig. 8 :is the outside view of the said plate, the needlebar, ratchet and pawl, and the tension-plate" ',-being itted to, move closely betweenthe teni.A

being removed. Fig. 9 is aside view of the shuttle. Fig. 10 isa vertical .section of the same and of the spool therein,` Fig. 1l is an end view of thellower end of the shuttle. Figa 12, 13, and Mare front views of three dili'erent relative positions of the shuttle, shuttlecarrier, and needle, exhibiting .three different' stages of forming the lock-stitch. Fig. 15 represents a portion of 4n glove-thumb, sewed with the straight seam on a lap-joint. Fig.

providedwith a toe, i', and

represents the zigzag stitch ou an edge toedge joint, or. a ush joint.

Fig. l8 shows two pieces of .skin, held in position on the finger-table by the presser-footfor edging. and

joining by the cross-stitch.

Similar letters'otvreference indicate corre4 1.sponding parte in the difierentiigures. i A is the frame of the machine, the horizon- .tal part a of which is attached,by=screws'ontd-.

a table. Aeasing, ttl, surrounding thepart O f machinery underneath the frame A, is fitted:

l1.16 is anu-enlarged section of the said stitoh,

through a suitable opening in the table. ai;

is theupright portion :of the frame, providedwith a horizontalshaft,B, revolved by 'treadleg motion, in the usual manner, transmitted `by- `a belt or oord to the `'pulley-b. A crank-pin, vtransmits the motion of the shaft B. to recip-` rocate a connecting-rod =or angular bar, Q,

which operates the shuttle, as will be herein-4 after described.

From-the shaft B; the necessary motion is transmitted to operate thek three main essential parts, viz: the feed, needle, and, shuttle. Onthe shaft B-are two cams, D E, for the movements of which ample room is provided by recessing an enlargement, a, of the ver-tie cal portion aot' theframe A, which parte3 will here call the head of the framer A.. Fis the movements-plate, mentioned in describing Figs. 7 andIS, attached to the head as. It is. .provided with a slot, f-,for guiding the. feed and presser-foot, and another slot, f', for gnidf.

ing the needle barslide. G isthe presserf. foot secured to a plate, g, whichlatter is also provided with a swiveled' guide-block, g, slid; ing in .the .slotjianda stationary block, .g having a toe-piece, g, and n pin projection, gf.'-

ilhe plate g is prevented from side play' by-1.4

the tensiomscrew, vthelatter passing throughs- 'an opening in the plate enlarge enough to el= .low of a free movement of thelastf n emcd' plate. Parallel with the `shattB is tltted a shaft, I, on which is pivoted a liftinghook, t', operated by the cam D. f

romeno i s the end of the wheel P either in one of the grooves p1, es shown in Fig. 4, or on two opposite of the projections p, as in Fig. 5, according to the position of the wheel P; thus, when the pawl B. is thrown in the teeth ofthe rntchet, oscillating thecrauk S for euchnpwsrd stroke of the slide M e distance equal to the depths of the grooves p1 and alternating the position of the needle laterally u distance equal to the ratio ol' the eccentricity of the needle und thetof the cr-.inlcpiu relative to the center of the needle-bar L. The Inovement of the feed nt the same time as the needle chunges position produces the zigzag stitch. T is the finger-table on sewing-table previously mentioned, being a. metallic tube closed nt the top (except the opening for the needle) und dat, so as form n. platform small enough lo enter the little linger of u. glove. This tube 1 has nu opening at the front of the upper end for the insertion ofthe shuttle, after which the opening is closed by e lid, U, fastened by e screw, t', and further held in place b v a spring, t, at the lower end ol' the tube, in such e. manner that the lid muy be opened by being slightly raised and then turned sidewise on the screw tl, to give access to the shuttle.

The lid U is provided ut the upper end with a small, thin projection, u', which, when the lid is closed, projects slightly above the tiet top or teble of the tube T, directly in frontof the needle, and serves to guide the seem, und also to divide the edges of the material in sewing n zigzag seem, a's shown in Fig. 18. The tube 'l is inclined in lintl with the needle, and has n ilunge nt its lower end by which it is screwed to the hollenr or concave portion of the horizontal purt of the frame A, as seen in the drawing, two parallel bars, V, extending from the flange through nu opening in the frame and terminating with u cross-bar, e', which serves as bearing for the shuttle-carrier. The shuttle-carrier W is e rod inclosed in the tube 'Lend provided at its lower end, below the frnnxe A, with u spirul groove or thrend, w, of a. large pitch und ofjust one turn, a portion of thc rod W above and below the groove w being cut down ilut to the depth of the said groove, us shown nt w1, Fig. 1. The upper cud Yol' the rod W is provided with n head fitted to revolve in the upper end ofthe tube T. This hond hns e smell projection, w', which enters und lits loosely in u notch, c, in the lower end ofthe shuttle X, so ns to rc volvo the shuttle with tho cnrrier W,nnd, with out separating them out oi' working order, to nllow the loop of tho upper thrend on being formed to pues through under tho shuttle, ho tween it und the hond of the rod W. The shuttle-carrier is revolved by the rod U, oporuted by the crunlsmovement from the shaft B. For this purpose a. round bar. o', clamped to the cud of the bont rod C, and is mudo dat ou one side, is guided between one of the bars V and the rod W--the flot side against the bur V und the round side against the rod W. While the baro' ou its stroke slides on the dat portion w of the shuttle-carrier, no movementof the lutter is produced, but when it enters und slides through the groove w,the shuttle is caused to make one revolution and revolve again once in the opposite direction on the return stroke of the har c.

The shuttle X is cylindrical and hollow, and u portion of its surface, at the lower end, is cut sway to form u thin broad hook, wl, for catching the threud olf the needle und carrying it around with the revolution of the shuttle to form n loop around the lower thread issuing from the spool in the shuttle through the slot und twice again in und out through holes on the shuttle, as seen in the drawing in Figs. 9, 10, 12, 13, und 14. Y is the spool held on the stud in the shuttle by the smal-l spring y'.

The forming of the loop and making the stitch is very plainlyr exhibited in Figs. 12 to 18, Fig. 12 showing the needle-thread just caught by the hook w1, the shuttle just started to revolve and form the loop; Fig. 13 showing the shuttle having completed its full turn und formed the loop ready to be drawn through between the shuttle und carrier-head by the upward movement of the needle; and Fig. 14 the loop of the needle-thread eucir cling the shuttlethreed, and nearly tightened by the further upward progress of the needle.

Z is the upper, and z' the under thread. A is a. plete hinged to e stud pivoted to the frame A, and which muy be swung partly around, raised up, and placed on the lingertable, as shown in dotted lines in Fig. 1, when it is desired to sew tint pieces only.

Having thus described my invention, what I claim es new, und desire to secure by Letters Patent, is-

1. The presser and feeder mechanism, cousisting' of the loot G und plete g, provided with the stationery block g2 nud swiveled block gl, thc latter sliding in the inclined slot f, in combination with the cuius D E on the shaft B, und the lifting hook or lever ion the shnft I, all constructed und operating substantinlly ns specified.

2. The gngewheel P, spring s, crunk-piu s, und crunk S, in colnbinut-ion with the needle-bnr L, haring the needle ctt-ached eccentricnlly, tho slide M, und the stationery puwi und coin-lover 1t r, ull constructed und operating substnntinlly un specified.

The atbovc specification ol" my invention signed by nin this lith dany ol' November, 1870.
