SPECIFICATION forming part of Letters Patent No. 395,372, dated January 1, 1889.

Application filed September 4, 1886. Serial No. 212,673. (No model.)

To all M71071 if; may 0071/0677L:

Be it known that I, LINGAN (f. WING, of l-loston, in the county of Suffolk and State of Massach useti s, have invented certain new and useful Improvements in Button-Sewing Machines, of which the following is a specification.

My invention relates to an organized machine by which to sew buttons upon fabrics IO or garments, and particularly to a machine or class shown and described in Letters Patent of the United States, granted to L. J. Driscoll December 1o, 1 Nos. 309,209 and 309,210, and December 20, 1883, No. 290,981.

It is the special. purpose of my invention to improve the machines disclosed in said Letters Patent to the end of securing simplicity and strength of construction in all of the elements, exactness and readiness of adjustment of such parts as it is desirable or necessary to have adjustable, and certainty and smoothness or steadiness in the operation of the entire machine.

Having thus indicated the nature and objects of my invention, I will proceed to describe the same, so that others skilled in the art to which it appertains maybe able to make and use it, reference being had to the accompanying drawings, and to the letters of reference marked thereon, the invention being particularly pointed out and distinctly claimed atthe end of the expdanat-ion of its construction and operation.

Of the drawings, Figure l represents a rear elevation of the invention. Fig. 2 is a bottom plan view of the same, the treadle-rod for operating the presser-foot, 820., being shown in sectioi'i. Fig. 3 represents a sectional plan view on the line 1 1, Fig. 1. Fig. l indicates a sectional detail view of the clutch mechanism on the line 2 2, Fig. 3. Fig. 5 is a similar view, the parts being represented in a different position. Figs. 6,7,and 8 are detail views hereinafter referred to.

Similarlet-ters of reference indicate similar parts in all of the figures.

Such devices and groups of devices as perform common and well-known functions and are fully understood by those skilled in the art and constitute no part of my present invent-i on will not be particularly described hereinafter.

In the drawings, A represents the bed, and B the overhanging arm, in which is journaled the needle-shaft C for operating the needlebar 1).

'E indicates the main shaft, provided with an eccentric, F, by which the conneeting-link G is actuated to impart motion to the needleshaft in the usual manner. 1

H represents the presser-bar for holding down the lnitton-carrier I, and such device or devices as may be considered as constituting the presser-foot.

The main shaft is provided with a worm, a, engaging the teeth of a pattern-wheel, b, provided with lugs or cam-pieces 0 (Z, the former adapted on one side to engage the adjacent end or finger h of a slide, 6, and the latter on the opposite side to come in contact with the laterally-proj ecting finger 0 of the latch-lever Z. As shown in Figs. 6 and '7, a ca1npiece, c, which is quite thin, is arranged close to pattern-wheel b and in the same horizontal plane as the end or finger h of slide 6, so that in the 7 5 rotation of said wheel said cam-piece maybe brought in contact with the end of the finger of said slide.

Laterally-projecting finger 0 of latch-lever Z is arranged at a lower horizontal plane than cam-piece and slide 6, so that in the rotation of wheel I; said cam-piece 0 will pass above said finger without touching it, while cam-piece d is offset from the lower face of wheel I), so as to pass below slide 6, but in the same horizontal plane with finger 0, and therefore adapted to be brought into contact therewith. The lower end, 7c, of shipper-handle K, rigidly secured to rock-shaft .I, is adapted to rest on the rear edge, e", of the go slide e, as shown in Fig. 53 and in detail in Figs. (3 and 8, when said slide is held by its actuating-spring (not shown) toward the pattern-wheel b; but when said slide is moved by the pattern-cams c in the direction of the ar- 5 row marked thereon in Fig. 2, said lower end of the shipper-handle will, by operation of spring j, which tends to revolve the shaft J in the direction of the arrow marked on said shaft, drop from the rear edge, e, of said slide 0o 6 onto the rear edge, e, of finger or offset 71, rocking shaft J in its bearings and permitting the arm j, rigidly secured to the outer end of shaft J, to be moved into the line or path of travel of the dog or clutch devicof, pivoted by the pin f on .and so as to turn with the main shaft, (the direction of movement of arm j being indicated by arrow 3 in Figs. 4 and 5,) causing said dog to ride up the inclined facej (see Figs. 1 and 2) of said arm j, turning the dog on its pivot against a spring, (not shown,) and disengaging it from a block or lug, j, on the driving-pulley and balancewheel L loose on main shaft E, and pern'iitting the said pulley and wheel to turn freely on the shaft without operating the same.

After dog or clutch device fhas been rocked to a sufficient extent by its engagement with the inclined face 7' of arm j to disengage said dog from the block or lug j" on the driving pulley and to bring the needle into its high-.

est position, the dog will be caused to abut against a pump-center or spring-pressed pin, g, (see Figs. & and 5,) set in a well or hole formed in an offset (see Fig. 1) formed on arm j, and thus entirely stop the rotation of said shaft with the needle up, as stated. The object of the pump-center or pin g is to cushion what would otherwise be a concussive blow given to the arm 7" by the dog in being suddenly stopped. Said pin, instead of being cushioned by a spring, mightbe made of solid rubber or similar material arranged in substantially the same way,with a similar result.

In Fig. i I have shown the dog fon the main shaft as engaged with the block 7' of the driving-pulley. This will be the position of the parts when, the machine is being oper ated, and the arm j is held out of the path of travel of dog f by lever K when the lower end, 7;, thereof is made to rest on the rear edge, e", of slide 6.

In Fig. 4; arm j is shown as having been moved inward in the path of travel of dog f, and thelatteras having ridden u p the inel ined face 7' of said arm, and said dog drawn away from blockj of the driving-pulley, and said pulley released from the main shaft, the dog J" having been brought against the springpressed pin g, which will be the position of the parts mentioned when the slide 6 has been moved in the direction of the arrow marked thereon in Fig. 9, and the lower end, 7;, of lever K has dropped from the edge e of the slide 6 to the offset edge e', permitting the spring] to rock shaft J, so as to move arm j from the position in which it is represented in Fig. 5 to that in which it is portrayed in Fig. 4:.

M represents a small bevel-gear secured to the main shaft E, and intermeshing with the teeth of a larger horizontally-arranged bevelgear, m,'turning on a stud, m, secured to the bed of the machine. Said wheel on is provided on its upper face with an irregular camgroo ve,

m (shown in dotted lines in Fig. 3,) into which a trundle-stud, n, extending down from the forward end of lever N, pivoted 011 the upper face of the bed at it, projects.

0 represents a rod connecting lever l with the button-carrier and presser-foot I. Said rod 0 is formed in two partsthat is, it is divided near its center and has a right-hand screw-thread formed on the end of one part and a left-han d thread on the adjacent end of the other part and an elongated right and left screw-threaded nut, o, screwed thereon by which improved means the rod 0 can be regulated or adjusted to regulate the position of the button-carrier and button laterall v that is, in the direction indicated by the double-headed arrow, Fig. 3as desired with respect to the needle. Jam or look nuts 0 o are screwed onto the ends of the rods, and after nut 0 has been properly set or adjusted are turned up against said nut to lock or hold it in position.

The revolution of wheel m imparts, through the medium of its cam-groove m acting on the trundle-stud 'n, a vibratory motion to lever N, which in turn imparts a like motion to the button-carrier and presser-foot I, pivoted at r, as hereinafter explained, through the medium of red 0.

To provide for the variatitm in the throw or extent of vibration of the button-carrier, I form a slot, or, in lever N, and provide a setnut, n for clamping or setting the stud upon which the end of bar 0, connected with lever N, is pivoted at any point within the limits of said slot. As it is desirable oftentimes to vary the extent of vibration of thebutton-carrier in a very slight (it-.Q'lfit, for various kinds of work, adjust-n'ient in this manner .is of the greatest impm'tanee and provides for results that could not be attained if lever N were provided at short intervals with holes in which the pivot-pin of rod 0 might be set.

To provide for the adjustment of the button-carrier and bu t-ton with respect to the needle at right angles to the line indicated by the d ouble-headeiil arrow before mentioned I form a screw-thread on the red I, to which rod 0 is pivot-ed, projecting rt-tarwardly from the button-carrier I, through a block or stud, p, projecting up from the presser-foot mech anism, and turn a thumb or set 111111, .1, on said screw-threaded end of rod P, providing a jam-nut, 1J2, for locking or fixing said rod in position after it has been once properly set or adjusted by the thumb-nut. This improved mechanism, like the means by which red O is connected with lever N, provides for adjustment of the button-carrier with respect to the needle to a degree of the utmost; nicetya matter of importance in lnitton-sewing machines. v

Lever Z, Figs. 2 and (i, is provided at its outer or rearward end with an offset or hook, Z", adapted to snap over the adjacent end q of lever Q by the action of spring Z when the end q of said lever is pressed inward by the operation of finger .5, secured to rock-shaft S, as hereinafter explained, as represented in said Figs. 2 and (j.

Lever Q is pivoted near its middle, as at q, to the bed of the machine, and at its forward end is pivoted to the rearward or outer end of a bar, R, arranged substantially at right angles to lever Q, and to whichbar Rthe button-carrier pivoted, as at r", Figs. 2 and 3, and shifts the latter by the operation of spring when locking-lever Z is disengaged from the end of lever Q by the action of one of the can1-lugs (Z on the finger 0 of said lever I. Pivot 1' extends through a slot (not shown) in needle or work plate R, said slot being elongated in a direction at right angles to main shaft E.

By dispensing with all of the devices intermediate of the lever Q and button-carrier Z, save the bar R, I am enabled to greatly simplify the construction of the machine at this point, securing entire certainty of operation and reduein liability of breakage and of the parts being disarranged or disordered.

S indicates a rock-shaft havingsuitable bearings in the bed of the machine, which rock-shaftis provided at its forward end with an upwardly-extending linger, s, the upper end of which rests against the rear edge of lever Q back or to the rear of its fulcrumpoint. At its rear end rock-shaift S is provided with a laterally-extending arm, 5-, (see Figs. 2 and 3,) the inner end of which is connected by a link, .9 with the rear end of a lever, 5, pivoted at .s to the overhanging arm 1%, and at its forward end exteinling under a lug, s, projecting laterally from the presserbar, as represented in Fig. 1, so that when the PIQSStW-bttl is raised to insert the work and anew button in the button-carrier, by depressing the rear end of lever s the shaft Swill be rocked, so as to cause its attached finger to move the rear end of bar Q inward in the direction of arrow 2, Fig. 2, so that the adjacent end of lever I will, by the action of spring Z snap thereover, all will, be readily understood by an inspection of Fig. 2 of the drawings.

In order to enable the operator to readily depress the rear or inner end of lever s, for the purposes explaimd, or to simply raise the presser-foot, I exteml connecting-link s by attaching thereto a rod, T, connected with a treadle, 1, adapted to operate on the floor,

whereby, when said treadle is depressed, the

rear end of lever s will be drawn down, with the result specified.

As shown, geanwhecl at has twicethe num ber of teeth that are formed in wheel M, so that the latter wheel will make but one revolution to two of the former. Consequently rod will be reciprocated once to each two revolutions of the main shaft E, and two reciprocatory movements of the needleebar, this timing of the parts being necessary in order to secure the descent of the needle first through one hole of the pair of holes in the button being operated upon, and then through the other.

If desired, wheel on, as is obvious, may be constructed with. a cam-groove in its periphery, similar to cam U, for operating the takeup devices, and be vertically arranged on an independent stud, instead of horizontally, as shown, and be operated by a gear similar to gear M on the main shaft. I prefer, however, the arrangement shown.

In operation, the parts being set and arranged as remesented in Fig. 2, except that a cam-piece, c, will have just passed finger h of slide 6, a four-hole button being in the button-carrier, and the goods to which the button is to be attached being placed under the presser-foot and the machine set in motion, the needle will descend and stitch first through one of the holes .2 and then the other until can'i-piece (I comes in contact with finger o of lever I, when the latter will be unlocked from lover Q, and the latter and bar R, with which it is connected, will be moved by the opertion of spring 0-, which will shift the buttoncarrier, (it being recolleeted that the buttoncarrier-is pivoted to bar R at r,) so that the needle will, operate through holes .2 .2" of the button, as through the holes .2, as beforeexplaincd, until one of the cam-pieces 0 comes in cont-act with finger 71 on slide 2, and moves said slide in the direction of the arrow marked thereon, when the lower end, 7;, of lever K will slip off the rear face, 6, of slide 6 onto the rear face, 6', of finger 71', permitting springj to rock shaft .1 in the direction of the arrow thereon, so as to carry the inner end of arm j into the path of travel of clutch-dog f, and operate the same, with the result hereinbefore explained.

To operate the machine to repeat the work of sewing on a button, after the latter is placed in position in the'cairier and the goods put under the presser-foot, the lever K is operated so as to rock shaft J in a direction opposite to the arrow, which will move arm j out of engagement with clutch or dog f, and allow the latter to become engaged by the driving-pulley L, and the main shaft: E to be operated. At the same time the lower end, 7a, of lever K will be moved rearward, so as to cause it to engage the rear face, 6, of slide 6, moved by a spring (not shown) in a direction opposite to the arrow marked thereon, when the operation of sewing on a button will pro.- ceed as before, the raising of the presser-foot and button-carrier having operated rock-shaft S, so as, through the medium of finger s, to move lever Q. in position to have the hooked end Z of lever Z snap over the end q" of lever Q, and hold the latter locked in the position in which it is represented in Fig. 2.

To operate the machine to sew on two-hole buttons cam-pieces (I will be replaced by campieces similar to those marked 0, and the use of leversl and Q and bar R and their ad juncts, constituting the button-shifting devices, dispensed with, the button-carrierhaving been adjusted so as to bring the eyes of the buttons in proper position with relation to the needle, when the machine will be operated and stopped at each quarter-revolution of wheel. 7) by the cam-pieces c comingin contact with finger ll of slide 6 and there being no shifting of the button-carrier.

By the improvements described it will be seen that the machine shown and described in the Driseoll patents, before mentioned, has been greatly simplified, rendered more compact in form, cheapcned in. construction, made more certain in its movements, less liable to get out of order, more readily adjusted to different characters and sizes of buttons, and made easier of and smoother and steadier in operation.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. In abutton-sewin g machine, as a means for readily and with the utmost nieety adjusting the button-carrier with respect to the needle on a line substantially transverse to the re ciprocating movements of the carrier, the combination, with a sewing mechanism, of a button-carrier provided with a rod, P, screwthreaded on its rear end, a presser-foot mechanism provided with a lug orbloek, 1), having a hole through which th e rod 1 passes,a thu mbscrew, 1), on, the outer end of the rod to adjust the button-carrier, and a lockingnut, p

to look the buttoncarrier in adjusted position, substantially as set forth.

2. In a button-sewing machine, a sewing mechanism, a button-carrier and means for operating it, the main shaft, a dog, f, pivoted thereon, a driving-pulley running loose on the main shaft and adapted to engage the dog and drive the main shaft, a rock-shaft, J, and means for controlling the movement of the same, and an ar1n,j, on the rock-shaft, provided with a springn'essed pin, and having the inclined surface 7' substantially as set forth.

3. A sewing mechanism and a button-carrier, in combination with a lever, B, directly connected with the button-carrier, levers Q and Z, for locking or holding the button-carrier in one position, lever Q being directly connected with lever R, and lever Z being directly connected with lever Q, a spring for moving the button-carrier to another position when released by the levers, the main shaft, and cams or wipers operated by the main shaft and arranged to operate on lever l, substantially as and for the purposes set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 31st day of August, A. D. 1896.
