sPEcIFIcATIoN forming part of Letters Patent No. 284,300, dated September 4,1883.

Application filed April 11, 1883. (Model.)

To aZZ whom it may concern:

Be it known that I, JOHN HEBERLING, a citizen of the United States, residing at Mount Pleasant, inthe county of Jefferson and State of Ohio, have invented certain new and useful Improvements in Running-Stitch Sewing-Machines; and I do declare the followingto be a full, clear, and exact description of the-invention, such aswill enable others skilled in the art to which-it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specifications My invention relates to that class of sewingmachines commonly called runningstitch or shirring machines.

The objects of my invention are, first, to

. furnish a device for making one or more rows efed in short folds in front of of runningstitches at the same timeby causing the goods tobe alternately raised and low: and against the point or points of the needle or needles, whereby a succession of uniform running stitches will be formed in the goods as the latter is drawn through the machine by the feed-rollers; second, to provide a convenient way by which the stitches can be lengthened or shortened at pleasure and instantly without removing or interchanging or substituting any in reciprocating or oscillating stitch-formers haying corrugated or recessed ends, and arpoints of the needles; second, in the vertically reciprocating or 0scillating stitch-formers, in combination with a curved needle or needles; third, in a slotted bell-crank lever and clamp-lever, in combination. with aseries of feed-rollers; fourth,in slotted bell-crank levers and adjustable crankpinsfor regulating the stroke of the stitch formers, fifth, in an adjustable pinion-bar, in combination with a hinged or pivoted stitchformer; sixth, in the combination of a gear meshing with grooved feed-pinions and needle-holders; seventh, in the combination and arrangement of other parts, hereinafter fully described, and pointed out in the claims. In the drawings, Figure 1 is a perspective outer or front face of the said slide. is a section cut through the enlargement of the stitch-former.

,Fig. 8 is a plan of the lower feed rollers or pinions, showing the circumferential channels or grooves and: needles laid therein. Fig. 9

is a side elevation of one of the curved 11eedles, and Fig. 10 shows an edge view of a piece of fabric as folded by the stitch-formers, and

the longer folds thereof as they pass through between the feed-rollers. The straight line drawn through the middle of the folds indicates the line of the needles and of the thread drawn through by the needles.

A is the frame, composed of the base-plate a, the crane a, and the short standard a The crane is provided with a head, (6, which is arranged over the cloth-plate a the latter being fiXedupon the standard a".

a is the slide, adjustable vertically, and it is held in any desired position by the thumbscrew a inserted from the rear side. of the head a l b is the main driving-shaft, journaled' in bearings provided on the frame A. On one end of the main shaft I place the driving. wheel and on the opposite end I fix an eccentric, ,b, and intermediately I place the eccentries 11 b The eccentric b is below the cloth plate and outofthe vay of the operator and of the goods which are being passed through the machine.

c is a supplemental shaft, journaled in'the frame, andhaving its end below the cloth-plate arranged immediately below the feed-rollers,

and provided with a gear-wheel, c. It is also provided, near its opposite end, with an enlarged portion or drum, 0 which is arranged on a line drawn midway between the two eccentrics 12 b To the shaft 0 is given an intermitting rotating motion, for purposes hereinafter explained. The eccentrics b b are arranged on opposite sides to each other, as shown, so that they act reciprocally.

d is a rocking shaft, journaled in bearings on the crane a. It has a slotted arm, d, at its rear end, and has at itsforward end the arm d", arranged just in rear of the head a The arm d is provided with pin (1", to which is attached the end of a pitman, d", which extends downward near to thelower end of the slide a and operates the carrier d pivotedto and near the lower end of the 'said slide. The carrier. d has the upper reciprocating stitch-former, d, fixed thereto. This stitch-former extends down in. front of the'points of the needles and is provided with short needle-slots d. In the lower end of the slide a there are mounted two toothed rollers or pinions, d d, separated as shown, and so arranged that they will mesh with the feed-rollers mounted on the clothplate.

6 is an arm, having on one end the ring 0, which is placed around the eccentric I)? To the other end of the arm 0, I pivot athreaded shank, e, which passes through a slot in abellcrank lever, and it is provided with a thumbnut, 6 (see Fi 4,) so that the threaded shank may be set higher or lower, for purposes hereinafter explained. I

To the ring a, I secure the lower end of a pitman, 6', the upper end of which is adj ustably connected to the slotted arm d on the shaft (1. By means of a set-screw, 6", the end of the pitman can beset at any desired place along the arm. (1, and the length of stroke of the latter be regulated at will, and thereby the length of the stroke of the stitch-former (1 will be also regulated.

There are attached to the eccentrics -5 6 arms 6 6 to which are affixed pivoted shanks and thumb-nuts, so that they can be adjusted, for purposes hereinafter explained.

f f are two bell-crank levers, sleeved upon the shaft 0 and abutted against the opposite ends of the enlargement or drum 0 andvthey are held in position by any ordinary means. The lower or depending arms, j, are slotted, and the pivoted shanks of the arms e e are held thereto by the thumb-nuts e".

g g are two friction-pawls, which have their outer ends pivoted to the upper arms of the bell-crank levers, while their inner ends bear on the drum 0'. Each pawl is so arranged that it binds on and causes the drum to rotate as the upper arm of the crank is raised. Nhen the arm falls, the grip of the pawl releases. The two pawls move reciprocally, and they give an interniitting movement to the shaft 0 through the action of the two eccentrics b b h is a bell-crank lever, pivoted to the standard of immediately below the cloth-plate and slide a It has its lower arm, h, slotted, and connected to the eccentric b by an arm, a, adjustablezpivoted shank '12, and thumb-nut 1?. On the upper horizontal arm, 71/2, I fix the lower 7 needle or needles securely in place.

stitch-former, i, which is arranged in front of the points of the needle and immediately below the upper stitch-former. The two stitchformers operate reciprocally, so that each will alternately engage the cloth and press it onto the points of the needles. The upper former presses the cloth below the plane of the point of the needle, and the lower former presses the said cloth above said plane. Thus the cloth is alternately doubled in short folds in front of and pressed onto the needles, where it is caught by the feed-rollers and carried along the needles and through the machine.

k, and k are three pinions or feed-rollers, mounted in suitable bearings on this clothplate. They are so arranged asto lie above or nearly above the plane of the upper surface of the cloth-plate, so as to give them a better action when they engage the cloth. The middle pinion, 7c", is raised about half its diameter above the pinions k 70. This construction and arrangement permits the curve of the needle to lie over the middle pinion, while its point rests on the front pinion, 7c, and the eye rests on the pinion 7c.

The pinions or feed-rollers k .k are arranged a little distance apart, and so that they mesh with the gear 0 on the shaft 0. The grooved pinion or roller 762 is journaled on amedial line between and slightly above the pinions k k,- but it does not mesh with the latter. The

needle, curved, lies over the roller lcflwith its.

point end resting in the groove in the roller is, and its eye or heel end resting in the channel in the roller 70. The pinions d are grooved corresp ondingly to the lower pinions, and when the slide a is let down the grooves hold the The up per pinions, (1 mesh with the pinions k 70 and g with the elevated pinion 70, so that the mo tion imparted by the wheel 0 is communicated to all the rollers'by positive action, by which a perfect, continuous, and regular feed is guaranteed.

All the pinions are provided with circumferential grooves in which the needles lie. I do not limit myself to the use of any particular number of needles. I make machines adapted to receive one, two, three, or more needles. The needles are removable, andone or more, as may be desired, can be used in the same machine.

By the arrangement of the feed-rollers or pinions, as hereinbefore described, Ihave placed them in close, compact form, and have so geared them with the driving mechanism that a perfect feed is secured.

The function of the fluted or cogged pinions IIO is twofold: First, the upper and lower series, when brought together, hold the needles in can beregulated at pleasure. l 3ythese means the reciprocating stitch-former can be so adjustedthat one of them will make a long and adjustment of the arms the other a short stitch. The feed of the machine is regulated by the e c in the bell-crank lever f f. The adjustment of the arms 6 6 may be such that the one will give a short stroke-to the bell-crank to which it is attached and the other will :give a long stroke, thereby regulating the feed to alternate long or short stitches. I am thus enabled by these several adjustments to make long stitches above or below the cloth and alternating short stitches.

It will be seen that the stitch-formers are provided with slots in their adjacent ends. In the operation of the machines the formers are passed inward past the ends of the needles, the latter entering the slots d. This is the preferable manner of construction and use; but I am enabled by other constructions to dispense with the slots d and at the same time press the goods onto the needles.

Having thus described my invention, what I claim, and dBSIIG'lJO secure-by Letters Patent,
