Application filed March 12, 1887. Serial No. 230,621. (No model.)

T0 to whom, it may concern.-

Be it known that I, CARL J. A. SJOBERG, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Button l lole Attachments; andl do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to simplify and cheapen the construction, and at the same the head of the machine being shown to illustrate the mode of attachment thereto; Fig. 2, a plan view of the operative parts, the cap be- 'ing in section, the position being at the beginning or ending of a button-hole; Fig. 3, a longitudinal section on the line 00 as in Fig. 2; Fig. a, a plan view corresponding with Fig. 2, except that the parts are in position just after the first turn-that is, at the beginning of the last half of the button-hole; Fig. 5, a 1ongitudinal section on the line 3 y in Fig. 4; Fig. 6, a front elevation of the attachment; and Fig. 7 a rear elevation thereof, the parts being in the same position as in Figs. 1, 2, and

3; Fig. 8, a plan view, the position of the parts being the same as in Fig. 2, except that the feeding mechanism is removed; Fig. 9, a similar view to Fig. 8, showing the parts in the saine position as in Fig. 1; Fig. 10, a plan View corresponding with Figs. 2 and 8, the feeding mechanism and cloth-clamp being removed; Fig. 11, a similar view to Fig. 10, the position of the parts corresponding with Figs. 4: and 9; Fig.12, an inverted plan View of the attachment complete; Fig. 13, a View of the crossslide detached; Fig. 1 1, an inverted plan View of the ratchet for operating the cross-slide detached; Fig. 15, a view of the cloth -clamp spring detached; Fig. 16, a longitudinal section of a portion of the cloth-clamp, showing the manner in which the length of the buttonhole is adjusted; Fig. 17, a side elevation of the forward end of the cloth-clamp and the work-holder, showing the manner in which the clamp is attached in place; Fig. 18, a side elevation of the frame-work, all the operative parts being removed; Fig. 19, an elevation of the cutting mechanism detached; and Fig. 20 is a view of the cutter detached.

The frame-work of the attachment, consisting of bed-plate 1,side pieces 2, and standard 3, is struck out and formed from a single piece of metal.

1 denotes the oscillating work-carrier; 5, the feed-rack, which is made integral with or secured thereto; 6, the feed-pinion which en-- gages said rack, and 7 the feed-wheel with which the feed-pinion is made integral or to which it is secured. It will be noticed (see Figs. 3, 4, and 5) that the edge of the feedwheel is provided with two rows or sets of teeth which are inclined in opposite directions. The upper row I have designated by 8 and the lower row by 9;

1O denotes the reversing-plate, and 11 a screw-pin securing the feedewheel thereto, all

of which will presently be more fully explained.

12 denotes the feed-plate, which slides in ways 13 in the side pieces of the frame-work, lugs 14 being provided to engage these ways. This plate is struck out and formed from a single piece of metal, and lugs 15 at the opposite ends of the plate are turned downward at right angles thereto, forming bearings which hold the plate securely in its operativ position.

16 denotes the feed-pawls, which are placed one above the other, and are secured by a screw-pin 17 to the feed-plate. It will be seen in Fig. 7 that one of these pawls engages the upper row of teeth, the other the lower row. The ends of both pawls are provided with downwardly-turned lugs 18, which engage openings 19 in the feed-plate to limit the motion of the feed-pawls. A spring or pair of springs 20, engaging the backs of the feedpawls, acts to force them both inward, so that each is in position to engage its corresponding set of teeth in the feed-wheel at the proper time.

21 denotes the feed-slide, which is provided with rack-teeth 22, which are engaged by rackteeth 23 on feed-lever 24.

25 is an operating-lever, which is provided with the ordinary slot 26 to engage the needlebar of the machine. The operating-lever and the feed-lever are both secured to the standard by a screw-pin 27. The upper end of the feed-lever is provided with a flange 28 and set-screws 29, the points of which bear against the operatinglever to limit the vibration thereof, so as to adapt the attachment to different styles of machines.

30 is a plate made integral with or secured to the feed-slide and which is provided with a pin or lug 31, engaging slot 32 in the feedplate, whereby motion is imparted to the latter.

33 denotes the cross'slide which operates the oscillating and shifting mechanism. This cross-slide moves in openings 33 in one of the side pieces of the standard, and is provided with an opening 34, said opening being provided on opposite sides with cam-surfaces 35. This cross'slide is operated by means of a cam 36 upon the under side of a ratchet 37. This cam lies within opening or yoke 34:, and is ordinarily made three-sided, as shown in the drawings, the cam and cam-surfaces 35 being so laid out relatively to each other that each actuation of the ratchet throws the crossslide to one extreme or the other of its move ment. For instance, to move it toward the right, one of the points 33 of the cam 36 would engage the right cam-surface 35, as the plate lies in the machine, and one of the sides 39 of cam 36 would be in contact with the left camsurface 35. To move the slide toward the left, one of the points would be in contact with the left cam-surface and one of the sides in contact with the right cam-surface. Cam 3G is actuated by a pawl 40, carried by feedslide 21.

4:1 denotes a spring acting to hold this pawl in engagement with the ratchet. The respective positions of this pawl in actuating the ratchet are shown in Figs. 2 and 4: and in Figs. 8 and 9.

42 denotes an oscillating lever carrying a double pawl 43 at its forward end, the functions and operation of which will presently be explained. This link is secured to the cross-slide by a pin 44:, and its rear end is socketed in a recess 45 in the bed-plate of the attachment. The oscillatory motion of the work-carrier is imparted through the crossslide.

46 is a screw-pin which passes through a slot 47 in the work-carrier and engages 1101c 48 in the cross'slide. The reversing-plate 10 is provided at its rear end with a slot 49, which engages a stump 50 upon a plate 51, adjustably secured to the bed-plate.

52 is a friction-spring secured to the bedplate and bearing on the reversing plate to hold it in operative position.

53 is a slot in the reversing-plate engaged by a pin 54, projecting upward from the bedplate, whereby the plate is held in position opposite sides of the V-shaped teat or projeetion, thus acting to hold either end of the pawl in engagement with its respective set of racleteeth upon the end of the reversing-plate.

It may be here observed that the pivotal point of the work-carrier 4 (or that point on which it swings laterally to enable the overedge or button-hole stitches to be produced) is coincident with the feed-pinion 6, said workcarrier having a pivotal connection with the cross-slide 33, which imparts the lateral oscillating movements to said work-carrier necessary for the production of the overedgc stitching, the bearing shoulders or disks 6G and (37, (hereinafterreferred to,) which hold the pinion 6 and rack 5 in engagement with each other, being concentric with said pinion.

As the pinion 6 and feed-wheel '7 are mounted on the pivoted reversing-plate, it is obvious that they will be moved laterally with the said plate when the latter is swung one way or the other, such lateral movements of the feedwheel and pinion and of the shoulders or disks 66 and G7, rigidly connected to and thus movable therewith, serving to give a suflicient lateral throw to the forward or work-clamp end of the said feed-plate to form the barringstitches at the ends of the button-holes and to bring the woikinto proper position beneath the needle of the machine to work the second side of a button-hole after the first side thereof has been worked, or to bring the work-clamp into its initial position for the working of a new button'-hole after the second side of a button -hole has been worked, such lateral movement being known as the shipper movemcnt,in contradistinetion to the vibrating or over-stitch movements.

The stump or projection 50, which extends into the slot. 49 of the reversing-plate, serves as a fulcrum forsaid plate, or as a pivotal point on which said plate will swing when operated by the pawl 43 in effecting the shipper or ship-over movements of the work-carrier. By loosening the screw by which the plate 51 is secured to the bcd'plate 1 the said plate 51 may be moved to adjust the fulcrum projection 50 in or out of the slot 49, and by thus changing the position of the said fulcrum the shipper movement may be regulated to vary or adjust the distance apart of the lines of IIC ' feed-rack 5 upon the work-carrier.

feed-slide.

stitches forming the workedbutton-hole,as may be required.

The operation of the parts already described .is as follows: Each upward or downward is caused to reciprocate through the engagement of pin 31 with slot 32 in the plate, so that each reciprocation of the feed-lever causes a reciprocation of the feed-slide and the feedplate. At the commencement of each buttonhole the parts are in the position shown in Figs. 2, 8, and 10. The reversing-plate is; swung toward the right, as in Fig. lO-thatis, looking from the front of the machine, asin Fig. 6. This of course swings the feed-wheel toward the right and brings the right feedpawl in engagement with its corresponding set of teeth upon the feed-wheel, the under set, as shown in the drawingsthat is, the set the action of which is to move the work-cal rier forward, as in Fig. 2. It will of course be understood that the feed-plate is recessed out to afford ample room for the movement of the feed-wheel, the recess being indicated by 59, (see dotted lines in Figs. 2 and 4,) the other dotted line in these figures denoting openings through the cap. (Shown also in Figs. 3 and 5.) This capis denoted by. 61, and is secured in any suitable manner to the side pieces. As the feed-plate reciprocates in its bearings, it follows that each forward movement thereof will cause the right feed-pawl to impart a forward movement to the feedwheel. When the plate moves backward, the pawl slips over the teeth in the usual manner, rc-en gaging the teeth again at the end of the backward movement, ready to carry the wheel forward again with the next forward movement of the feed-plate. As the feedpinion and feed-wheel move together, it follows that the work-carrier must move forward through the engagement of the pinion with The 05- cillation of the work-carrier, whereby the cross-stitching of the button-hole is produced, is accomplished by the movement of the cross-slide, to which it is pivoted, as already explained. Each forward movement of the feed-slide causes pawl 10 to engage ratchet 37 and impart a movement thereto, which,by means of cam 36 and cam-surfaces 35 upon the cross-slide, imparts to said slide a movement in one direction or the other. While the work-carrier is moving. forward the right point of double pawl 43 rests upon the smooth surface 62 at the end of the reversing-plate between the two sets of rack-teeth 55 and 56, as in Fig. 10, said pawl and the reversing-plate being inoperative during this? forward movement. The forward movement continues until the end of the button-hole As already stated, feed-plate 12- is reached, at which instant stump'63 upon the under side of the work carrier engages lug 64 on the double pawl 43, tripping said pawl and bringing the left point thereof into engagement with the left set, of ra-ck teeth at the rear end of the reversing-plate, (denoted by 56.) It will be seen that spring 58, which engages teat 57 on the double pawl,

, acts to hold it in either position into which it may be thrown, and that friction-spring 52 acts to hold the reversing-plate in position, so that at each movement of the cross-slide toward the right the left point of pawl 43 will slip backward over one of the rack-teeth in set 56. The movement of the cross-slide toward the left of course carries lever 42 and double pawl 43 in that direction, so that through the movements of the cross-slide, link, and pawl the reversing-plate is quickly moved from'the position shown in Fig. 10 to that shown in Fig. 11, which completes that end of the button-hole. As soon as the reversingplate and the left point of pawl 43' have reached the position shown in Fig. 11' they bot-h become inoperative again. While these movements of the reversing-plate have been taking place the feed-wheel has of course been inoperative, as neither feed-pawl'has been in engagement therewith. As soon as the movement of the reversing-plate is com- .pleted and the left point of the double pawl engagement with the other row of teeth-in the present instance the upper row-in the feed-wheel, as in Fig. 4a This reverses the movement of the feed-wheel, and consequently of the feed-pinion, so that the work-carrier begins 7 to travel backward to complete the other side of the button-hole. The movement down the other side of the button-hole continues-until adjustable stump 65 upon the under side of the work-carrier comes in contact iwith lug 6i on the double pawl 43, which trips it again and brings the right point thereof in. engagement with the set of teeth 55 at-the forward end'of the reversing-plate. The action in reversing is the same as before until the right point ofpawl 43 has acted upon each tooth in set 55 in turn, from the outer one inward, which completes the other end of the button-hole, the parts being again in the position shown in Figs. 2, 8, and 10. It is of course preferable .to run a few stitches over the point at which the stitching comin slot 68 at the rear end of the work-carrier over the edge of the rack and the upper one .side of the feed-wheel, the lower one resting resting in a recess 59 in the feed-plate. These shoulders serve as bearings and hold the parts firmly in position in use. i

It will be noticed in Figs. 2 and 4 that a gage G9 is provided upon the top of the feedwheel, and in Figs. 4 and 8 that a gage 70 is provided upon the top of the work-carrier by the side of slot 71. Stump 65 upon the under side of the work-carrier is made adjust able by means of set screw 72, which passes through slot 71 and engages said stump. The adj ustinent of this stump determines the point at which the second crossing orbarring of the button-hole takes place-that is,- the point at which the second movement of the reversing plate takes place. The attachment illustrated in the drawings is capable of producing an inch-'and-a-quarter button-hole for its larger size.- If a button-hole of this size is desired, set-screw 72 is loosened and the stump pushed to the extreme forward end of slot 71. If a half or three-quarter inch button-hole is desired, the stump is set to the proper position,- as indicated by gage 70, in order to make the second crossing, barring, or turn at the proper time. The position of the work-carrier and clothclamp when commencing to work the buttonhole is determined by the adjustment of the feed-wheel, which is provided with a fingerknob 73,for convenience in operation, this finger-knob being always within reach through the opening in the cap. (See Fig. 3.)

7i (see Fig. 5) denotes aprojection or point in the edge of opening through the cap, which is the mark used to determine the position in which the feed-wheel is to be set when abutton-hole of a certain length is to be made, as determined by the position of adjustment of the adjustable stump (i5.

Supposing it is desired to make a half-inch buttouhole, the parts being of course in the position shown in Figs. 2,- S, and 10, the feedwheel is moved forward until the point 'marked one-half on gage 69 is brought in line with projection 74, when the machine may be started. it As stated above, While either point of double pawl 43 is acting upon the reversing-plate, both feed-pawls are out of engagement with the feed -wheel; consequently no forward movement of the work-carrier takes place until movement of the reversing-plateis completed, so as to bring the feed-wheel into position to be engaged by the other feed-pawl.

hen the attachment is not in place upon the machine, the work-carrier may be readily moved backward or forward by rotation of the feed-wheel by hand. In order, however, to prevent the work-carrier from moving far enough in either direction to allow either of the stumps 63 or to forcibly engage lug 64 on the double pawl, and thus prevent the reversing mechanism from acting, I have provided a stop 75, preferably made integral with friction-spring 52, which engages shoulders 76 in the edge of the workcarrier, thereby limiting its movementin both directions and avoiding the possibility of either stump moving far enough to anything more than trip the double pawl, thus preventing injury to the reversingmechanisin.

7 7 denotes the needle-hole in the bed-plate. The forward end of the work-carrier is of ordinary construction, and is provided with the usual opening 78. H

79 is a cloth-clamp having flanges 80, which extend down into this opening," thus holding the work firmly, and rearwardly-extending arms 81, which are joined by a cross-piece 82.

83 denotes lugs which project downward from the cross-piece, and are provided with notches 84, adapted to engage projections 85 on the edge of the work-carrien I I 86 denotes a standard projecting upward from the work-carrierbetween arms 81 of the cloth-clamp. A j

87 denotes a clamping-lever pivoted to the standard. The head of this lever has two straight faces, one of which is continuous with the handle and the other at right angles thereto,the face in line with the handle being at a greater distance than the other from the pivotal point, so that when the handle is turned downward the cloth-clamp is pressed down upon the work-carrier, flanges 80 passing into opening 7 8. \Vhen the other face of the clamping-lever is in contact with the clothclan1p'that is, when the'handle is in the raised position, as in Fig. 17-the cloth-clamp is raised above the Workcarrier by the action of a spring 88 lying under said carrier. Any style of spring may of course be used for this purpose, although I preferably make a special spring having a plate 89, with a slot 90, adapted to engage the standard. The spring, being simply slipped over the standard, is held firmly in position at all times without the use of rivets or screws.

In order to provide simple and convenient means for cutting the button-hole after it has been stitched, Ihave devised a cutting mechanism adapted to be used in connection with the needle bar, cap, and standard 86, which I will now describe.

91 (see Figs. 2 and 19) denotes a plate substantially' a right angle in form, which is provided with a slot 92,- adapted to engage standard Siiabove clamping-lever 87 when it is in the locked position, with needle-holes 93, to adapt it for different button-holes, different machines, 850., and a rearwardly-extending shank 94:,- which is bent downward and rests in a loop 95, formed integral with the cap, as clearly shown in Figs; 6 and 7.

96 (see Figs. 19 and 20) denotes a cutterblade, the edge of which is made of just the required length to cut the special length of button-hole that is being stitched.

Plate 91 is provided with a downwardlyprojecting flange 97, the ends of which are curved around, forming sockets which embrace the cutter. The cutter is firmly secured in place by a set-screw 98, which passes through slot 99 in the cutter and engages flange 97. V

The operation is as follows: The cutter has tobe placed in position for each button-hole;

but as there are no adjustments it takes but an instant to do so. The shank simplyhas to be slippedwinto loop 95 and the plate passed over the standard which engages slot 92. To cut the button-hole, the flywheel of the inachine is moved by hand, which of course brings the needle-bar down and causesthe end thereof denotedby 100 to engage the top of plate 91 on opposite sides of the special hole through which the needle passes. This of course forces the cutter down and cuts the button-hole,

101 denotes the slot in the bed-plate through which the cutter passes in cutting a buttonhole. Itshould be noticed (see Figs. 11 and '12) that this slot is placed at one side of the needle-hole in the bed-plate, and is wholly independent thereof. The slot is made long enough to accommodate any length of buttonhole, and no changes in the attachment are required in cutting different lengths. The cutting is of course done when the needle-bar is down, at which instantthe work-carrier is oscillated toward the left, as seen in Fig. 2, so that the cutter-blade enters said slot without interference with any part of the machine or attachment.

In use the attachment is secured directly to the rear slide 102 of the machine. V

103 (see inverted plan View, Fig. 12) denotes screws which pass throughzthe slide from beneath and engage the bed-plate 1 of the attachment.

104 denotes a longitudinal slot in the slide which curves out to the edge thereof, forming a strip 106.

105 denotes a set-screw which passes through the bed-plate of the attachment, the point of which engages the outer side of slot 104, acting to spring strip 106 outward against the slide-groove (not shown) in the bed-plate of the machine, thus locking the attachment firmly in place.

The operation of the attachment is briefly as follows: The rear slide of the machine is taken out and the attachment secured thereto. The slide is then pushed into place and locked there by set-screw 105. The feedwheel and adjustable stump upon the under side of the work-carrier are adjusted to the proper length of button-hole, the work placed in position under the cloth-clamp and secured there by the clamping-lever. The operation of stitching the opposite. sides of the button-hole and barring the two ends and the movements of the parts in accomplishing this result have been so clearly described as not to require repetition. \Vhen a buttonhole is completed, the cutter, without disturbing any of the parts, bya single movement of the fly-wheel, is caused to cut the button-hole. The cutter is then removed, the cloth-clamp lIaving thus described my invention, I
