MATTHEW GOULD, OF BELFAST, IRELAND, ASSIGNOR TO CHARLES MCCLOSKEY AND HENRY MCCLOSKEY, OF BELFAST, IRELAND.

MACHINE FOR DOING OPENWORK-STITCHIN G.

T call whom it may concern:

Be it known that I, MATTHEW GOULD, a

subject of the King of Great Britain, residing-- Under my inventionthe needles work together and they are simultaneously moved.

in the same direction, that is, to the one side or other so as to make the double zig-zag stitch. The needles are not moved near to and then away from one another as in the well known spoke stitch machine.

In order that my said invention may be clearly understood I have hereunto appended explanatory drawings whereon:

, Figure 1' is a side elevation ofa spoke stitch machine of well known type with my improvements applied thereto. Fig. 2 is a plan of the machine. Fig. 3 is a view of the cam for operating the vibrating quadrant which vibrates the needles. Fig. 4 isa view of the needleblocks with their needles. Fig. 5 is a cross section taken on the line w, :20, Fig.

4' andshowing the arrangement of the needles and punches. the stitching.

On the drawings the same reference letters wherever repeated indicate the same parts.

In carrying out my invention, say for pro- Fig. 6 is a diagram showing ducing two rows of hemstitching on handkerchiefs, I arrange on the needle bar a of 2.

Wheeler & Wilson spoke stitch machine, two vibrating blocks 1), c, the block I) being provided with a needlee and the block 0 with a needle The needle bar has, fitted to it,

two punches g, 77,, the punch gbeing at the back of the needle 6 and the punch h at thefront of'the needle f. The needle block b has a rod 41 secured to it and this rod, at its upper end, is attached in the usual manner Specification of Letters Patent.

Serial No. 295,409.

[ to a link k which has, at its one end, a guide; slot lc working on the pin k and, at its other:

end, is connected adjustably to the usual vibrating quadrant Z which is fulcrumed at l The needle'block c has also a rod j secured to it which, at its upper end, is connected in the usual manner to a link m having, at its oneend, a guide slot m working on a pin m and, at its other end, is adjustably connected to at second vibrating quadrant n fulcrumed' at n;

Instead of the usual cam for operating'the vibrating quadrants, I use a special cam p.

which is shown at Fig. 3 to an enlarged; scale. 1 and 2 and depressions at'S.

the cam are duplicates. The pinto offthes quadrant Z and the pin 0 of'thequadrantn;

work in the groove of the cam.

It will be seen, es ecially from the enlarged view, Fig. 4, t at the needle blocks are arranged .close together and so also are Of course the arranged.

The cam p is rotated in the usual manner by means of gearing from the shaft in the arm and as it rotates the so called quadrants- Z, n, are caused to vibrate and they communicate their movements to the links is, m, the rods 'i, and the'needles e, When the pins 0, 0 are in the position shown at Fig. 3, that is, at the points 1 of the cam, they move the quadrants Z, 11, away from one another to; their fullest extent and bring the needles in line with the punches (see full lines, Fig. 4)

This cam is made with projectionsa-t.

Both ends-10f:-

and when the pins are opposite the pointsZ:

of the cam the same thing'oocursbut when the pins are at the points 3 of the cam. the

quadrants are brought near-to oneanother with the result that the needles e, f, are moved to the one side, the needle f being moved away from the punches while the needle e is moved from its position opposite the unch g to a position 0 osite'the-punch h. In this manner the needles aremoved; si-

multaneously either to the one side, as clearly indicatedin dotted lines at Fig; 4. oritozaposition in linewith the punches, asclearlyvinldicated; in full, lines at Fig. 4. movement of the needles istotherightihan'd: side of Fig. 1 but of course it may be to the left hand side according to the position of. the hem. The feed mechanism is the same- The; lateral.

as that employed in the U. S. patent to Joseph Walker #634,970 granted October 17, 1899.

I will now describe the formation of the stitch with reference to the diagram at Fig. 6. When the pins 0, 0 are in the position shown at Fig. 3, thatis, opposite the parts 1, 1, of the cam, then the needles e, f, are in line with the punches g, h. The cloth is meanwhile being fed forward and. at the end of its forward movement the needles enter it at Z, Z, (Fig. 6). After i the needles rise again, the cloth moves backwards and when the backward movement ceases the

parts

2, 2, of the cam are acting on the pins 0, 0 and the needles enter the cloth at 2, 2, (Fig. 6). When the needles rise again, the cloth is again moved forward, and, at the same time, the cam moves round so as to bring the

parts

3, 3, opposite the pins, 0, 0 with the result that the needles are moved laterally and enter the cloth at 3, 3, (Fig. 6). The usual gap in the feed cam for operating the feed carrier now comes into action and allows the carrierto drop with the result that the cloth remains stationary for an interval. When the gap has been passed the cloth recommences its forward movement and, at the same time, the parts 1, 1, of the cam 10 come into action-on the pins 0, 0 with the result that the needles are brought back to their original position opposite the punches and at the next descent they enter the cloth l, 4; thereafter, the stitches are repeated in the same manner as already explained.

It will be seen that there are two parallel lines of punch holes at 1, 1, 2, 2, but there are no punch holes at 3 where the thread passes through the hem of the cloth.

The stitches at the back of the cloth are made in the same manner as on an ordinary Wheeler & Wilson spoke stitch machine.

It will be seen that the needles have two movements in the line of the punches and thcpn a single lateral movement to the one s1 e..

The stitching produces a very pretty effect on handkerchiefs and such like.

By spoke stitch I mean a stitch such as shown for instance in the patent to Walker above referred to.

By arranging the unches so that one shall be disposed in t e rear of one of the needles I am enabled to better produce the zig-zag stitch with minimum movement.

Having now fully described my invention what I claim and desire to secure by Letters 2; A sewing machine having two needles movably arranged on the needle bar side by side transversely of the direction of feed, two unches, one arranged in line with each needfe, vibrating means for the needles, and a cam for operating said vibrating means so as to give the needles two consecutive movements in order that they may enter the cloth twice in line with their respective punches and then a simultaneous lateral movement in the same direction to enter the cloth at one side of the punches.

3. A sewing machine having two needles arranged on the needle bar side by side transversely of the direction of feed, a punch arranged in rear of one needle, a punch arranged in advance of the other needle and means for imparting to the needles a simultaneous lateral movement in the same direction at every third descent of the needle bar.

4. A sewing machine having two needles arranged side by side. on the needle bar, a punch arranged in rear of one needle, a punch arranged in advance of the other needle and a cam for imparting to the needles a simultaneous lateral movement in the same direction at every third descent of the needle bar.

5. A sewing machine having two needles arranged side by side on the needle bar, a punch arranged in advance of the one needle, a punch arranged in rear of the other needle, and means for causing the needles, during the formation of the stitch, to enter the cloth twice in line with their respective punches and then once to move simultaneously in the same direction at the one side of the punches, and means for imparting to the cloth one backward movement followed by two consecutive forward movements.

6. In a sewing machine the combination with the needle bar, of needles movably secured thereto, rods connected with the needles, links connected to the rods, two quadrants, a cam for operating the quadrants so as to impart to the needles a simultaneous lateral movement in the same direction at every third descent of the needle bar and means for rotating the cam.

7. In a sewing machine the combination with the needle bar of needles movably secured thereto, punches, rods connected with the needles, links connected to the rods, two quadrants for actuating the links, a cam for moving the quadrants away from one another so as to bring the needles in line with the punches twice in each revolution and drawing them together so as to throw the needles to one side of the punches once in each revolution, and means for rotating the cam.

8. In a sewing machine the combination with the needle bar of two needles movably secured thereto, a punch arranged in rear of the needles, a punch arranged in advance of the needles, rods connected with the needles, links connected to the rods, two quadrants for actuating the links, a cam of oblong shape and having two corresponding projections at each end and two corresponding depressions at the center for actuating the quadrants and means for operating the cam.

9. In a sewing machine of the character stated, the combination with the needle bar and needles movably secured thereto, quadrants operatively connected with said needles, and means for moving said quadrants in opposite directions, the needles being at the same time moved in the same direction.

10. .In a sewing machine of the character stated, the combination with the needle bar and needles movably secured thereto, of quadrants operatively connected with said needles, and a cam operatively connected with both of said quadrants for moving said quadrants in opposite directions, the needles being at the same time moved in the same direction.

11. In a sewing machine of the character stated, the combination with the needle bar and needles movably secured thereto, quadrants operatively connected with said needles, means operatively connected with both of said quadrants for moving said quadrants in opposite directions, the needles being at the same time moved in the same direction, a punch arranged in advance of one needle, and a punch arranged to the rear of the other needle.

In testimony whereof I afliX my signature in presence of two witnesses.
