JOHN REEOE, OF BOSTON, MASSACHUSETTS;

BUTTONHOLE SEWING-MACHINE.

SPEGIFIGATIQN forming part of Letters Patent No. 494,280, dated March 28, 1893. I Application filed AugustZS, 1892. Serial No. 443,885. (No model.)

that class of button-hole stitching machine in which thework to be stitched is held by a suitable work-clamp while the stitch forming mechanism makes the stitches for covering the edge of the button-hole slit, the stitchforming mechanism and Work-clamp having combinedwith them suitable mechanism by which to change their relative positions during the operation of stitching each buttonhole. In this class of machine as heretofore constructed it has been customary to put the material in the work-clamp, and then close said clamp on the material by a hand operated lever, the actvof clamping the material effecting the starting of the machine and its operative parts in the proper order, the machine being automatically stopped at the completion of a button-hole. So also in the class of machine referred to it has been customary to stop the stitching actioifof the stitch forming mechanism as the latter arrives at the small end of the button-hole, but thereafter the rotation of the belt wheel employed for driving the main shaft has been continued to I effect such further relative movements of the stitch and cutter-carrying frames as to enable the cutter to be brought into cutting position with relation to the work-clamp, and

anism into position with relation to the workclamp and also to actuate the cutting mechanism to cut the material and bring the needl e into stitching position with relation to the cut button-hole, the relative distance of movement of parts at each throw of the lever shall be increased or the feed stroke vbe made longer, thus saving time between one and the "next stitching operation. In the-class of machine referred to the feeding movement has whereby the act of putting the material into.

position to be clamped effects the starting of 1 6o t the machine so that a cam forming a part of the machine will thereafter automatically effect the closing of the work-clamp, and at about the same time another cam will act to quickly operate the cutter to cut thematerial then held in the work-clamp, and the cutter will then be permitted to rise and the movement of the machine will be continued until the stitch forming mechanism and the cut button-hole are in proper relative positions .to commence the stitching thereof, when the stitching of the button-hole will be eifected and the machine will beautom'aticallystopped. In this my present invention the movement of the machine during the clamping and cutting of the button -hole and the bringing of the cut button-hole and stitch forming mechanism into operative position is effected at a substantially high speed and preferably by devices having ascontinuous rotation, and as soon as the stitch. forming mechanism arrives in operative position the feeding movement of the machine is automatically reduced and made intermitting during thetime that the stitch forming devices operate to form stitches. The placing of the material in position in the work-clamp may be made to elfect the stating of the machine in various ways, I

machine herein represented, as I have embodied my invention, there are two pulleys which are rotated constantly, and one or the other, not both at the same time will control the feed movement of the machine, or the In the,

too

relative movement of the stitch frame and clamp-frame. Each of these pulleys as constructed forms part of a clutch, and when one is operative the feeding movement is at one speed, and when the other is operative the feeding movement is at faster speed.

Inasmuch as many of the parts of the machine herein to be described are very similar in their construction and action to parts in United States Patent No. 349,359 granted to me, I will briefly refer to some of such parts before particularly describing the more special pointsof novelty to be herein covered.

The frame (1, having an overhanging arm and an attached curb or casing of constitutes what I shall call the stitch-frame; and the plate a what I shall call the clamp-frame. The stitch-frame contains ashaft a provided near its left-hand end, see Figs. 5 and 11,

viewing the front of the machine, with acom-. pound eccentric, to be hereinafter further described, which actuates a lever o suitably jointed to the needle-bar Z), having an eyepointed needle, such needle-bar having its bearings in a loose circular block having attached to it a partial gear LP. The shaft a has a disk a provided with a hole a see Fig. 11 to receive a pin f see Fig. 2, extended from a plate f provided at one side with an eccentric hub f made hollow for lightness,

and surrounded by and adapted to actuate a linkfi jointed to the rear end of a lever g pivoted at g on a leg or stand fixed to the casing at, said lever actuating theball-ended elbow lever A having its fulcrum on a pin A in brackets or ears depending from the partial gear g connected tothe shaft A mounted in a hub or bearing at one end of the casing a said shaft having at its upper end a throatplate having a needle-hole and a gimp-hole, the said shaft also carrying a race-way block A in which is reciprocated a segmental carrier B to which is connected the curved under thread-carrier 3, said carrier B deriving its movements from the lever A through a link B connected toit and to a stud extended from the said carrier. The needle has co-operating with it a looper 2 which takes the needle-thread below'the material and draws it back and holds it for the passage through it of the under thread carrier, said looper being attached to a looper carrier A actuated by or through a slotted arm A entered by a stud A carried by the lever A. The two partial gears 01 and g are engaged respectively by teeth at the end ofv the two pivoted segmental levers e and e connected by an upright rod e extended down through the clampframe and the casing a, the lever 6 having at its inner end a roller or other stud e which enters a cam groove 4 at the under side of what I shall herein designate as a cam device, it being represented as a cam wheel or circular plate j, the hollow hub of the latter rotating about a hollow sleeve extended upwardly at the center of the casing a see Fig. 4, the link f before referred to being extended through the hollow center of the said cam device and the hub of the casing.

The devices thus far referred to, to efiect the stitch-forming movements of the stitchforming devices, and their rotation about the eye of the button'-hole, are and may be all as in my patent referred to, except that the double eccentric for reciprocating said needle bar is not found in my said patent.

Referring now to Figs. 5 and 11, the shaft a has fast to it a disk a provided with a pin a which enters a hole in an eccentric 0, surrounding the shaft 0, and free to rockor slide somewhat with relation to said shaft owing to an elongated slotd in the said eccentric. This eccentric is surrounded by one end of an eccentric strap a suitably jointed to the rear end of the needle bar actuating leverc'. The eccentric a has a .pin a which enters a hole in a link a surrounding an eccentric a fast on a sleeve a surrounding the shaft a said sleeve being held in adjusted position in the stitch-frame by or through a collar a, held fast to said sleeve by a screw (1 said collar having a bifucated arm or portion at, see Fig. 3, which is extended through a slot in the stitch-frame said arm being adapted to be clamped to the stitch-frame by means of a screw a screwed into the space between the two arms made by slotting or dividing said each stitch in order that the needle may be properly timed to'correctly co-operate with the looper and the needle-thread carrier. This double eccentric has been particularly described in order that the necdlemovcment may be thoroughly understood, but the double eccentric isnot herein claimed for the reason that-it has been used in my machines for many years, I having commenced its use shortly after the date of my first patent in 1881. The

cam device j at its lower side has a second cam groove or cam face 7 which receives in it a roller or other stud Z of an arm 1 connected to a rock-shaft Z, mounted in bearings atv the rear end of the casing a, said 'rock shaft having preferably integral with it an: arm Z having a stud Z on which is mounted a suitable swivel block which entersand slides in a groove herein marked Z made longitudinally in the underside of the clamp-frame a, see Fig. 4. V

The cam device has at its upper side a groove 6 in which is entered a roller or other stud j fixed to and depending from the clampframe. If the cam device is rotated while the clamp-frame is anchored or restrained against 7 longitudinal movement, the said cam device,

owing to the fact that it rotates about a center of motion fixed in the casing (1 will cause the relative positions of the stitch-frame and clamp frame to be changed, and in the plan herein illustrated and referred to, the stitch frame and stitch-forming mechanism therein will travel over the clamp-frame in a straight line and when the active part of the cam 7 comes against the stud Z the rear end of the stitch-frame will be given a lateral movement so that the needle carried by said stitch-frame will be given a motion to follow along and about the outline of the eye of the buttonhole. It will be understood, however, that should the stitch frame be anchored orheld firmly rather than the clamp frame,then in such plan the conditions would be reversed and the stitch frame would stand still and the clamp-frame would slide and be moved out of straight line to enable-the work-clamp holding the material to move the latter in the proper lines to enable the stitching to go about the eye of the button-hole. relative movement of position of stitch frame and clamp-frame is provided for in like manner in the patent referred to.

The cam device has at its upper side near its centera cam 57 which acts on a toe 58 of a cutter-carrying lever G, pivoted at G and provided with a cutting-blade G of a length the material.

stitch-frame.

The same adapted to the length of the button-hole slit, said pivot G being'held in suitable ears on the stitch-frame. The button-hole cuttingblade operating as a single stroke cutter, cooperates with a suitable cutter bed G held in place on a projection of the casing at by a screw n. t

The clamp-frame has, as shown, connected to it by

suitable screws

62, 62, plates m m, on which are located cars 24, which receive pivot pins 23, on which are'mounted'the clamp levers 22, provided at their free ends, as herein represented, with pivoted clamping plates m,

each of said levers having jointed to it an r L-shapedlink 26 which is extended below the plate m, and acted upon by a spring-arm 28 of an arm 29 attached toarock-shaft 30, there being two such arms. The plates m in practice have serrated clamp members m?- connected' thereto and adapted to engage the material under the plates 'm'. Each plate'm at its under side near its inner end see Fig. 3,

has a suitable stud 65 which acts against inclines or shouldersn see Fig. 8, of a spreading device shown as a'plate fixed under the cutting bed, said spreading device acting to spread the button-hole clamp or work-holding device after the button-holehasbeen cut in The plates m, m, are'connected together by a suitable spring 96."

The clamp-frame and the work-clamp, the button-hole cutter, the rock-shaftpand its arms 29 to close the clamp, and the cam for IOO closing the cutting mechanism are all as in said patent.

The shaft a at its right-hand end viewing the front of the machine,- has loose upon it a pulley f co-operating with which is a dog f and other co-operating parts, not necessary to be particularly described, constituting a clutch mechanism substantially such as shown in United States Patent No. 367,063, said dog when in engagement with the clutch pulley enabling the latter, which is rotated continually, to effect the rotation ofithe shaft a the stud carried at the upper'end of an arm f 14 forming part of a three-armed lever or rock-shaft being atsuch time held out of the path of rotation of the said dog. The said three-armed lever has its bearing in a tubular or sleeve-like hub f forming part of the The arm F of the saidlever has at its front end a suitable adjusting screw as F which co-operates with the outer end of a slide pin (3 guided by a guide-platef see Fig. 8, and by the stitch-frame, and which pin 0 rests upon a cam 0 made in the upper side of thecam device, said cam haviu g an abruptshoulderf and an inclinef When the slide pin 0 in the rotation of the cam device j rides up upon the higher part of the cam 0 the arm having the stud f is put out of the range of motion of the dog f and the pulley f is then caused to rotate the shaft a and the stitching of the button-hole takes place; but as soon as the said pin drops from the abrupt end of the said cam the stud referred to immediately comes within the range of movement of the dog f and. effects the release of the pulley f from the shaft a and the stitching movement of the stitch forming devices is immediately stopped. The arm f of the three-armed lever referred to is joined by a rod 0 with one end of a lever 19 pivoted at 19 on a stud in a bridge-piece Z2 crossing the cam device j and connected to the casing of. The lever Z1 has an extension Z7 pivoted by link 12 to a hub Z1 loose on the actuating shaft b, said hub supporting a loose pulley sired that the actuating shaft Z1 be rotated continuously by the fast speed pulley Z1 The shaft Z7 has a worm i which by its engagement'with the Worm teeth t of the cam device j rotates the said cam device, the movement being either intermitting' or continuous according to which of two clutch pulleys has control of the shaft b The shaft a has fast upon it. an eccentric 19 see Fig. 5, which through ancccentric strap 11 is connected to a pin 19 having a foot I), shown by dotted lines Fig. 10, which enters a slot b in a pawl-carrying arm b mounted loosely on what I have denominated the actuating-shaft 17 said pawl-carrier having coned, in one direction of the stroke of the pawlcarrier, to engage teeth of the ratchet wheel c fast uponthe shaft I).

This pawl near its outer end hasa pin a which enters aslot in a friction plate a, surrounding the shaft 1) loosely at one side of the ratchet wheel, said plate being acted upon by a ring a in turn acted upon by a spring (1 said ring being held from rotation bya pin. e By means of this friction plate the pawl a when on its reverse: stroke is given a slight movement away from the ratchet wheel a so that the pawl does not click over the ratchet teeth.

When the clutch pulley f is to rotate the shaft a and make stitches, the arm f willbe moved to the right Fig. 1 far enough to enthe lever F is moved by the cam e to disengage the clutch pulley f from the shaft a to stop the stitching, the movement of the lever b, Z2 will slide the pulley b on the shaft 1) so that, its clutch part I) will. engage the clutch I1 and then the pulley 19 in continuous rotation will rotate the shaft 5 continuously and at a faster speed.

The end of the lever Z7 opposite to that joined to the link 0 has co-operating with it a slide 0 see Fig. 2, one end of which has a suitable projection e which is acted upon and locked in place by one end of a starting device (2 represented in Figs. 1, 3 and 9 as a sort of lever, pivoted at e and having a finger e extended partially across the machine substantially at right angles to the length of the button-hole, said finger lying preferably between the upper and lower members'of the clamp, so that when the material, (a buttonpiece or other article to be provided with button-holes, or to be stitched.) is put into the clamp said finger will be made to occupy part of the position occupied by the material, so that said finger 6 may be readily moved manually as the material is being m'anipu lated, or said finger e may be moved by the finger of the operator, the turning of the starting lever from any cause releasing the slide rod 0 so thatit may be moved forward,

or to the right, see Fig. 2, by the spring 0 connected to it and to the clamp-frame. The clutch parts b, Z9 are disengaged when the work-clamp is open, as in Fig. 2.

The rotation of the shaft 19 starts the cam device j, and the latter instantly by the end n of a cam it, see Fig. 7, moving with the cam device, acts on a slide rod 6 causing it to be depressed so as to effect the depression of a lever e" pivoted at e and connected by link e with one of the arms 29 used to close the work-clamp as before described. Preferably the rod 6 will act on an adjusting device 16, shown as a screw having a check nut 167, rotation of the said adjusting device in one or another direction determining to a nicety the extent of the closing movement of the work-clamp. In this way the first effect of moving the starting device in the act of putting the work into the work-clamp is to efiect the automatic closing of the work-clam p, and at substantially the same 1 time the cam IIO 57 of the cam device acts to turn the cutter lever G and automatically cut the work held in the cloth clamp.

The drawings show the parts of the ma chine in position to receive the material to be cut and stitched, the clamp being open, the cutter elevated and the machine at rest, with the exception that thetwo clutch pulleys f and Z9 are running loosely. In this position the end of the lever 12 see Fig. 2, contacts with the slide bar 0 the spring 0 is slightly stretched and the outer end of the said bar is held looked back by the starting device. Now the operator while, or in the act of putting the work into the clamp causes the starting device to be moved thus releasing the slide. bare and permitting the spring 0 to turn the lever Z9 sufficiently to efiect the engagement of the clutch pulley 19 with the proper part of the shaft Z1 and said shaft will be started in rotation, rotating the cam device and causing the cam n to effect as described the closing of the clamp, and as this is done the cam 57 actuates the cutting mechanism at the button-hole, and then the cutter rises from and the cam 6 brings the cut button-hole into stitching position, and the incline. f of cam 0 turns the three-armed rock-shaft, causing the stud f to release the dog J so that the belt wheel f may be coupled with and rotate the shaft a to actuate the stitch forming devices, and also to intermittingly rotate the shaft Z2 and the cam device j, but to do this, just as the three-armed rock-shaft is turned against the tension of spring 0 to release the dog f, as described, the arm f pulls upon and turns the lever Z9 far enough to cause the clutch pulley Z9 to be disengaged from the shaft b which it at such time was rotating. The rotation of the shafts a and b by or through the clutch pulley f is continued until the button-hole has been stitched, at which time the pin 0 drops ofi the abrupt shoulder f 17 of the cam 0 This dropping of the pin allows the three-armed rock-shaft to be moved by the spring f see Fig. 1, thus bringing the stud f in position to turn the dog f and cause it torelease the pulley from the shaft a As the three-armed rock-shaft is turned as described by the spring f, the spring 0 pulling on the lever 73 effects the re-engagement of the clutch parts Z2 Z), and again starts the fast and continuous rotation of the shaft b and the cam device j, the cam n thereon as the continuous motion of the cam device commences, relieving the pin 6 from pressure and permitting the spring 29 to act on arm 29 and open the clamp. During and following the opening of the clamp the cam 6 acts to cause the change of position of the stitch-frame and clamp frame to bring the cutting mechanism into operative position. Just before the parts come into cutting positionthe end of the slide bar strikes the end of the lever 19 and moves it sufficiently to effect the release of the clutch parts 19 and 11 and the machine is again brought to rest with the end of the starting device holding the slide bar 0 The machine will now re main at rest until the starting device is again moved.

In practice the speed of the machine is such and the operator will so manipulate the work by hand, that as soon as the clamp is opened said operator will, as quickly as possible, feed the Work the distance of a button-hole and then as quickly move the starting device and in this manner the cutting and stitching are kept in rapid succession without any loss of time of the machine or the operator.

This invention is not limited to the exact shape shown of the device or bar 0 between the starting device and the lever Z1 or between the starting device and the clutch Z9 b to effect its engagement on the movement of the starting device after or while putting the work in the clamp. After the cutting of the button-hole has been effected, and during the relative change of position of the stitch frame and clamp frame the spreader W, by contact with studs 65, one on each of the plates m, see the detail Fig. 3, acts to effect the spreading'ofthe button-hole ready to be stitched.

This invention is not limited to the employment of devices of the exact form shown between the starting device and the means for moved too far toward the operator by mo mentum I have provided the rod-with a spring r connected thereto by a screw 4", the .free end of the spring contacting with the front side of the starting device. The arms 29 in practice are kept elevated by a spring 29*, see Fig. 2, fast on an ear 3O of the clamp frame, the said ear receiving the rock-shaft 30.

In Figs. 13 and 14,1 have showna modified form of starting mechanism which I will now describe briefly. The slide bar 0 like that shown in Fig. 2, has a projection 200 which is acted upon by one end of one of thearms 29, said arm in practice, however, being normally lifted a little higher by the spring 2.) than required in Fig. 2, so that the arms 28 shown in Figs. 2 and 3 and also fully in Fig.3 will contact with and slightly lift the inner ends of the plates m, m which are held loosely on the clamp-frame. When the inner ends of the clamp-plates m are held up slightly one of the arms 29 keep the slide bar 0 back, but as the operator puts the work into the jaws of the clamp the slightest downward pressure depresses the inner ends'of the clamp plates and arms 29, thus releasing the slide bar 0 when the fast speed clutch is brought into operation as before described.

In Fig. 15, I have shown a modified form of starting device consisting of a lever 5 pivoted at s on cars at the under side ofthe clamp-frame, said lever having one end 5 adapted to meet and look back the slide bar 0 the opposite end of said lever having its end suitably adapted to be engaged or struck by the finger or hand of the operator when putting the work into the clamp.
