Specification forming part of Letters Parent No. 10.609'. dated Marcil 7,1854.

.To al?, whom it may concern.- n

Be it known that I, CHARLES MILLER, of

'the city and county' of St. Louis, and State of Missouri,

Similar letters of reference indicate corresponding parts in both figures. The sewing-machine to which these improvements relate is of that description in which the stitches 4are formed by the interlaeing of two threads,

one of which is passed through the cloth and left protruding inthepforrn yof a loop, and the other is carried bya shuttle through the said loop.

My invention relates to the adaptation of the cloth or other material to be sewed to receive what aretermedthe .button-hole stitch,77 the whip-stitch, and the herring-bone f stitch;77 and it consists in givingthe cloth or 1 material to be sewed a movement laterally to l the direction of the seam and in opposite directions, alternately, between every two stitches, in addition to the movement commonly given in the direction of the seam. The button-hole stitch and 'whipstitch are both made in the same way-by taking one'stitch through the cloth and the next over the edgethe only dierence being that in making the button-hole stitch the movement in the direction of the seam requires to be much less than in making the whip-stitch, being properly only the distance of one thickness of thread. The herring-bone stitch is made by taking all the stitches through.

To enable those skilled in the art to make and use my invention, I will proceed to. describe its construction and operation. l

The working parts of the machine represented in the accompanying drawings are all carried by a bed-plate, A, supported lon standards B B. The needle is carried by a vertical slide-rod, C, which is fitted to a suitable guidestoek, D, and attached to a beam, E, which lreceivesan oscillating motion through a cam, F, on the driving-shaft G, and thus communi-v cates a reciprocating motionto the slide-rod and needle. Ihe shuttle H is tted to a pickerbox, .I, which works in a raceway, I, sunk in the -bed-plate, receiving motion through .a picker-staff, K, which is caused to vibrate horizontally below thc bed-plate by means oi an eccentric, L, on a vertical shaft, M, 4 which is driven by a pair .of bevel-wheels, a a, from the driving-shaft. The cloth or. material to be sewed is fed by a drum, N, which is 'fitted to turn loosely on a fixed axle, O, below the bed-plate, the upper part of the periphery of the said drum standing slightly' above the upper face of the bedfplate. which has a suitable opening to admit it. The feed-drum receives motion upon its'axis at propei` intervals-that is, between every two stitehesby means of a band, b, which passes roundv it from the hub of a ratchet-wheel, P, which is iittedto turn freely on a fixed stud, c, the said ratchet-wheel being actuated by a click, d, on a lever, Q,'whose iulcrum is on the stud c, and which is acted upon at the proper intervals by a lever, (notshowm) which -receives motion through a cam, R, at the bottom of the verti cal shaft M.' The above parts do not :diii'er sewing-machines; and therefore they are only described as far as is ,necessary to elucidate the present improvements.

semicircular arcs of different radii, united at end of a screw, j, in the upper end of a lever, T, of the iirst order, whose fulerum, is a pin, h, in an arm standing out from the backof the framing. To the lower endof 'this lever T is attached a rod, U, which passes nearly horizontally under the center-'of the bed and axis of the feed-drum through a guide, i, and carside of the feeding-drum.

materially from corresponding parts in other Y The feed-drum N is so tted to its axle that both ends by steps, and this cam acts upon theV ries a fork, V, which bears against the back l When the drivingl shaft is rotating, the larger and smaller radii of the cani are alternately in operation 011 the screw j. While the screw bears upon the larger arc of the cam, the drum is pushed forward on its axle by the fork V; but when it bears on the'snialler are the drum is moved backward by the spring f, the latter moving forth and back in the direction of its axis, as the screw j ascends and descends the steps on the cam, and being retained in eitherits backward or forward position long enough to allow the stitch to be made. These changes in the position of the drum take place at about the saine time as its rotary movements l'or thefeeding of the cloth, or during the time that the needle is not in the clot-h. The friction-roller \V, which holds the cloth down firmly on the feed-drum, turns freely on a stud, 7c, which is fixed in a cheek, Z, at the lower end of a vertical rod, 11., which slides up and down, but does not turn in, guides m m on one side of the fraining of the machine. No spring or weight is shown for holding` the roller down upon the cloth, as its-own weight, with that of the rod I, 1n ay be sufficient lnsewing thebuttolrhole or whip stitch, the cloth is laid on the bed-plate with its edge or the edge ol` the hole at a right angle to the In sewing the herringbone stitch, the cloth is laid so that the needle always passes through the cloth, but makes two parallel rows of perforations, entering in one andv the other row7 alternately.

Vhat I claim as my invent-ion, and desire to secure by Letters Patent, is-

Giving theeloth or material being sewed a `movement laterally to the direction of the seam, between the successive stitches or interlacings of the needle and shuttle threads, substantially as set forth, for the purpose of receiving different kinds of stitches or seams.
