BUTTONHOLE-SEWING MACHINE. I

Specification of Letters Patent.

Patented Jan. 16, 1906..

Application filed April 19, 1902. Serial No. 103,742-

0 To t whom, it may concern:

Be it known that I, HENRY C. MILLER, a

iritizen of the United States, and a resident of Waterford, in the county of Saratoga and State of New York, have invented certain new and useful Improvements in Buttonhole- Stitching M achines of which the following is a specification.

This invention relates to improvements in multiple but tonhole-machines used primarily for simultaneously making .buttonholes in- .collars, cuils, or the like articles.

Heretofore in the manufacture of collars and cuffs the end buttonholes were made individually but this means proved to be too slow and could not be relied upon to produce the end buttonholes exactly the same distance from the center or from the ends or edges of a collar or cuff. Moreover, by making one buttonholc at a time in a collar unnecessary handling is occasioned and considerable expense is added to its manufacture.

My invention comprehends, broadly, the placing of two buttonhole-cutting and stitchin g-inachines in position to operate at the ends of a collar or end and a centralizing mechanism to properly and quickly locate the collar between gages adjacent each sewing-machine to ermit the quick and ready insertion of a col ar to produce therein the end buttonholes at exactly the same distance from the center and end. i

In order that the sewing-machines may be operated simultaneously to form the two end buttonholes, I'have provided mechanism to simultaneously actuate the starting mechanism of the two machines, and as the thread of one of the machines is liable to break or become out of order, and hence produce an imperfect buttonhole, I have provided means whereby either one or the other of them may be independently thrown into operation. This is vitally important in an organized multiplebuttonhole machine, and I regard it as essential toward making a practical and commercial apparatus.

My invention also relates to improvements in the manner of mounting the sewing-machines that they may be adjusted to or from each other to operate upon collars of diilerent lengths and be turned to produce buttonholes of varying angles to suit diil'eren't styles of collars.

The invention further relates to a centralizing device arranged intermediate two buttonhole-sewing mach nes, such device having means to positively engage the collar to cooperate with gaging devices located equal distances therefrom to make the end buttonholes exactly the same distance from the center of the collar.

Many other objects and advantages will be hereinafter referred to, and be particularly pointed out in the claims.

In the drawings, Figure 1 is a top plan view of my improved multiple buttonhole-sewing machine, showing the machines conventionally, one being dismantled. Fig. 2 is a longitudinal section on the line 1 1, Fig. 1. Fig. 3 is a transverse section on the line 2 2, Fig. 1. Fig. 4 is a detail rear elevation of the driving mechanism. Fig. 5 is a detail plan view of a guide-block on which one of the machines is mounted. Fig. 6 is a detail plan view of one of the cloth-clamps and a gage adjacent thereto. Fig. 7 is a detail section of-the same on the line 3 3, Fig. 6. Fig. 8 is a detail plan view of a portion of the centralizing device. Figs. 9 and 10 are details of a detent used in connection with the centralizer. Fig. 11 is a detail view of the equalizing-bar and cooperating parts. Fig. 12 is a diagram showing varying angular positions the blades of the machine may assume. Fig. 13 is a similar View, but showing the base and bed of the machine.

The numeral 1 indicates a bed or supporting-table mounted on legs and havin 1n, its upper surface ways 2, along the edge e which is a scale 3. Two blocks 4 4, having flanges lapping the under side of the bed, are adapted to he slid to or from each other, each having a central seat 5, opening 6, and depending threaded niit 7, and one of the blocks has a pointer 8. A rod 9, having right and left hand screw-threads 9 and 9, extends from. side to side of the bed and is mounted in bearings 10, the threads en aging the respective nuts 7 7 under the blOCiS 4 4. On screwrod 9 are nuts 11 11, adjusted to prevent endwise movement of the rod after it has been set. A detachable handle 12 affords convenicnt means for turning the rod to move the machines to or from each other. The rod not only adjusts the two machines, but holds them in position after the adjustment is made. I

13 13 indicate two buttonhole cutting and stitching machines of any appropriate type. However, I have shown, for convenience, machines in which a gage cloth-plate 14 moves laterally, and as the buttonholes are rrade the collar is moved back and forth the distance of the buttonhole. My invention is not limited to buttonholemach. nes having this characteristic, for in other machines the needle is moved around the contemplated buttonhole during the stitching operation, and my im rovement can be used with 1na- .chines of this ty e as well as with the ma.-

chines shown an described.

Generally each machine is mounted on a base 16, having a depending boss 17, which rests and turns in the seat 5. A pivot or bolt 18 fits in the opening 6 in the block 4 and engages a threaded opening in the boss 17. A scale 19 onthe upper face of the block 4 is 'drawn on a line struck from the center of the ivot 18, and a pointer projecting from the base 16 coacts with said scale to indicate to the operator what circular movement has been given the machine that she may set it to produce a buttonhole of the desired angle.

20 indicates a cutting-blade and 15 a needle, the center of the cutting-blade always being in exact alinement with the center of the pivot 18, so that it is immaterial at what angle the machine may be set the relationship between the pivot and blade will remain the same.

The driving mechanism is indicated at 25, and the starting-lever at 26. The connections and details thereof being old in the art itis not deemed necessary to describe them in detail.

The machines are constructed exactly alike, except that the cloth-plate and clamp are made right and left to make buttonholes at an incline from the center of collar. The mountings of the two machines are also similar, so that they are adapted to be adjusted at any preferred angle in relation to a straight line drawn through the pivots of the two machines. In any adjustment of the two machines to form end buttonholes the middle of sa d buttonhole will be on lines coincident with the centers of the pivots on which. the machines are turned. Therefore the center of the buttonhole-cutting blades of the sewing-machines are and must be in exact center of the buttonholes at the time of out. This location of arts is highly important, as it is this relationship which enables me to use any kind of buttonhole-stitching machine.

Adjacent the gage 'cloth-plate is a clamp 28, having an opening through which the needle passes, and it is pivoted at 29 and extends beyond the pivot to form a lifting-lever 30.

It is essential in order that either collars or cuffs may be (:perated upon that each machine be provi ed with a right and left hand to the structure shown, as other devices may be employed to accomplish the same result. It is necessary that the collar when flattened out engage a stop to insure that the contemplated end buttonholes be located exactly equidistant from the center of the collar and also properly distanced from the upper edge and ends of the collar. To accomplish this'important result, I have provided a guideway 31 on the gage cloth-plate 14, and working in this uideway is a slide 82,having a slot 33, throug which passes a set-screw 34 to hold the slide in fixed position after it has been adjusted to suit the length of the collar in which the buttonholes are to be made. A second slide 35 is adj ustably mounted on the slide 32 by a set-screw 36, passing through a slot 38 and entering a threaded opening n slide 32. The inner end of slide 35 has formed with it a depending lug 39, which constitutes a stop or gage for the end of the collar. The lug 39 is in the plane of the collar, so that when the latter is flattened out to be operated upon the gage fixes its location, so that each buttonhole will be located at a predetermined. pont. Ord narily the adjustment of slide 35 will be suific ent to position the gaging device; but for longer collars than the swing of this slide will permit the other slide 32 will be adjusted, which will permit of the locating of the gage parallel with the proposed buttonhole, wh ch saves readjusting the other gage. It is evident that by turning the slides around and adjusting them ample space is provided for gaging cuffs.

An equalizing-bar 45 to simultaneously operate the starting mechanisms of the stitching-machines and also to release a centralizing device is mounted under the bed 1. This bar is centrally pivoted to a rod 46, which is ivotally connected to a foot-lever 47.

reeper 48 on the rod 46 forms a guide for a spring 49, said spring having one end fastened to the rod and its other end to the bed 1. The equalizing-bar is wholly supported by the spring, and the latter is prevented from swaying by the keeper 48. Stirrups 5O depend from the base of the machines and the ends of the egualizing-bar are guided in them, the upper e spring against the stirrups to limit its u ward movement. A chain. or other flexible connection 52 is suspended from each starting-lever 26 of the stitching-machines, and at the lower ends of the chains are adjustably-supported stirrups 53. The bar 45 under'normal conditions is limited in its u wardmovement by the stirrups 50, and the stirrups 53 being properly adjusted the ends of the bar pass freely through the latter, so that when the machines are adjusted and the gaging device to coact with the clamp and operator relieves pressure on the foot-lever gage cloth-plate, one form of which is illustrated in the drawings, particularly in Fig. 6. However, I. do not desire to be limited j 47 there will be no friction or binding between the bar and the said stirrups 53. The object of this feature of my invention is to ge of the bar being drawn up by thei for the bar 15.

reduce the friction between the parts to a minimum, so as not to interfere with the delicate and intricate movement of the automatic stopping mechanism of the stitchingmachines, for if there is friction to overcome the needles will not stop in their proper position to start the succeeding buttonhole, which would cause delay when another collar is inserted to be operated upon. This construction will permit of the two stirrups 53 being drawn down together to simultaneously start the two l uttonhole-stitching machines, and when the operator relieves pressure on the pedal the stopping mechanisms will have absolutely nothing to interfere with their movement during the formation of the buttonholes, and are therefore free to be automatically stopped.

In a dual buttonhole-sewing machine it. frequently happens that a thread of one machine may break, which produces an imperfect buttonhole. In order, therefore, that this imperfect buttonhole may be worked again without operating the companion machine, I have arranged a crank-shaft at each end of the frame 1 to coact with the equalizing-bar 45. There will be two of these shafts 56 56, one for each machine, each mounted in bearings 57 57, each having a crank portion 58 and a handle 59. The crank 58 of each shaft normally rests on the upper edge of the equalizing-bar, and as the latter is pivoted at its center to the rod 46 and its opposite upper end bears against its stirrup one end of said bar 45 may be depressed, and the stirrup-and-chain connection adjacent thereto will be pulled downwardly and start one of the sewing-machines without affecting the other, the stirrup of the machine of the one being operated acting as a fulcrum In this way either of the machines may be operated independent of its companion, with or without lifting its respective clamp, so that with my machine a buttonhole may be made either at one or both ends of a collar. Furthermore, if two 'buttonholes have been cut and one imperfectly finished the imperfect one may be stitched without relieving the clamps which hold the collar and without starting the companion machine. Even should the operator remove the collar and it has been found that a buttonhole is not perfect the end of the collar can be again inserted and the machine started and go over its same course again. This result can only be accomplished by providing a centralizing device, cooperating end gages, and mechanism for simultaneously or indepcmdently controlling the buttonholestitehing machines, all of which mechanism is herein set forth.- Furthermore, if one ma chine becomes inoperative and requires repairs another may be substituted, and in a short time the dual machine is ready for operation.

A second equalizing-bar 60 is mounted under the bed of the machine and its ends pass through stirrups 61 61, depending from the blocks 4 4, the upper edge of the bar bearing against the upper part of the stirrups. A rod 62 is pivotally connected to the bar 60, and at its lower end it is connected to a treadle 63. A spring 64 is connected at one end to the rod and at its other end to the bottom of the bed, and to prevent the spring swaying it passes through a keeper 64 fas-r tened to the rod. To the ends of the levers 30 are attached chains 65, on the lower ends of which are stirrups 66, and through these stirrups freely pass the equalizing-bar 60.

The purpose of the equalizingbar 60 and its connections is to simultaneously elevate the clamps 28 for the insertion of the ends of the collar. Obviously when the treadle 63 is depressed the equalizing-bar will pull down on the chains, and they in turn, the levers 30 and the clamp will be elevated, and upon re lease of pressure on the pedals suitable springs will return the clamps to their normal positions.

In connection with the buttonhole-stitchin machines for forming the end buttonho Ies in collars, &c., and the gaging devices coacting therewith I employ a centralizing device to engage and position the collar to insure operation of the stitching mechanisms to form buttonholes eq uidistant from the central buttonhole. This centralizing device, broadly stated, comprehends mechanism for placing a collar in position relative to the buttonholeanachines, whereby'the buttonholes produced by said machines will be located at a predetermined distance from an indicated point in the collar, previouslyformed central buttonhole being shown for this purpose in the drawings, which show one form of my invention. to accomplish the desired result. A fixed'support 67 is fixed to the bed 1, and at its upper end it is formed with a split bearing 68 and a coacting setscrew 69. A horizontal bar of a work-support, 70, is mounted in the bearing 68 and is adapted to be adjusted to or from the operator by manipulating the set-screw 69, so as to change the position of the centralizing engaging detent to suit collars of varying widths and styles. A work-supporting plate 71, having a detent-seat 71, is fixed to the bar,

IXO

and at the outer end of the latter is a workguide 72, hinged at 73 and rovided at or near its opposite end with a etent or locating-guide 74, held in place by a threaded portion 75. (See Fig. 10.) A spring 76 on the hinge 73 tends to throw the arm upwardly when its inner end is not held by a cooperating latch. Adjacent the detent or locatingguide two leveling-arms 77 extend from the bar 70, each being provided with a slot 79, through which a set-screw 80 passes to fix them in an adjusted position on the bar.

The leveling-arms extend downwardly in opposite directions from the bar and rest on the Work-sup orting plate 71 and are intended to assist in eveling the collars toward the respective machines when they are being positioned to be operated upon. bar 70-is pivoted a latch 83, the upper end of which is adapted to engage the work-guide 72 when it is thrown down with a collar, while the lower end of the latch is bent at an angle and is providedwith a projecting foot 84, a sprin 85 engaging a seat in bar 70 and the an ar part of the lever to keep the upper on of the lever in the path of the Work-guide 72; A step or rest is indicated at 7 2, against which the work-guide strikes when disengaged from the; latch,- as' shown in dotted inesinFig. 3.

A short shaft 861s suitably mounted under the bar 70, and extending from said shaft are arms 87, su porting arod 89, which is directly under the not 84. A short stem 90 extends from the op 'osite side of the shaft 86, and it has swivele to it a chain or like flexible connection 91, the swivel being adjustable by means of the screw-and-nut connections 92.

It will be noted by reference to the drawings that the chain has in its length a short spring 93 to form a yieldin connection. The spring is connected to t e pedal 47, and its functlon is to revent undue pulling on the shaft when pulling on the bar to start the machines. I

The bar and plate 71 for convenience in defining the structure constitute the worksupporting plate, andI have so designated it in t 1e claims.

The parts thus assembled, the operation is substantially as follows: The operator will adjust the two buttonhole-stitching machines the proper-distance apart by turning the rod 9, thisdistance always depending on the length of the proposed collar to be operated upon, the adjustment being determined by the scale 3 and pointer 8. The next step in the setting of the machines is to release the screws 18 and turn the two machines on their pivots to accommodate the angles of the proposed buttonholes, for it must be remembered that the angular arrangement of the end buttonholes vary according to the style and shape of the collar. The second adjustment having been made, the scales and pointers 19 enabling the operator to set the two machines precisely alike, the screws 18 are tightened-up. These distances having been determined the gage 39 is adjusted, and it only remains to adjust the detent 74 accordin .to the style and width of the collar. If a co lar is to be operated upon which has pre viously had its center buttonhole completed, the detent or locating-guide will be in the form of a blade and will engage the buttonhole, while if a collar not having a buttonhole is to be operated upon then a mark in In a slot 82 in 74, While the work-guide 72 is in an elevated the collar will indicate its center, and in lieu of a blade a pin 100 (see Fig. 8) will engage the center marked in the collar. In order that these various adjustments may be quickly made, I propose to make up a series of scale-cards corresponding to the different styles of collars. If, for instance, a particular style of collar is to be operated upon, it would only be necessary for the operator to refer to a scale-card of-the particular style and number desired and read therefrom just what adjustments are required, the scales on the machine being in harmony with those of the card. A collar to receive the end buttonholes is placed on the detent or locating-guide position against its rest 72*, and the workguide and collar are now thrown down and the end snaps behind the latch 83, the detent or locating-guide entering an opening or seat 71- in the work-supportin plate. The collar is now fastened on the tab e by the detent or locating-guide and is leveled by the arms 77, whereupon the operator having previously depressed the foot-treadle 63 and elevated the clamps 28 quickly adjusts the edgesof the collar against the gaging projections 39, and the pressure is relieved from the pedal and the clamps are dropped and securely hold the collar against the gages. The collar being secured in fixed position relative to the buttonhole cutting and stitching machines, the operator depresses the treadle 47, which pulls down on the stem and rocks the shaft 86, which in turn elevates the rod, which strikes the foot 84 and rocks. the latch 83 on its pivot and releases the work-guide 72, and under the'infiuence of its spring the locatingguide is disengaged from the collar and is elevated and rests against its support 72". This operation also pulls down the chains 52, which acting on the starting devices simultaneously starts the stitching and cutting mechanisms, and when the buttonholes are completed the machines automatically stop. While the stitching operation-is going on, the

operator skilfully applies another collar to the locating-guide, and by the time the'buttonholes are completed she has the next collar ready to be inserted against the gages and between the clamps. v which the end buttonholes have-been made, the operator depresses the treadle 63 and elevates the clamps and also inserts the ends of the collar to be operated upon.

An operator becomes adept in the use of the'machine, and, as above indicated, a collar can be on the work-supporting plate and engaged by the locating-guide and the ends ready to be placed under the clamps before the operation of completing the buttonholes in the preceding collar is completed. Even with such quick manipulation the one and all important result is accomplished, and that is that every collar is perfectly positioned un- To release the collar in on A der theclamps and against the gages beforo the locating-guide is lifted, insuring the end buttonholes being exactly the same distance from the center, ends, and edges of the collar and precisely at the same corresponding angle.

in selecting buttonhole cutting and stitching machines it is immaterial what make machines are employed. As before stated, the conventional machines shown in the drawings are of the type wherein the gage clothplates are movable, and it is only necessary to change one so that one will move to the right and the other toward the left to accomplish the results herein described. However, to use any make of buttonhole cutting and stitchin machine to operate at opposite ends of a colIar and yet be susceptible to pivotal movement to change the angles of the buttonholes in different collars it is of the utmost importance that the center of the buttonhole-cutting blade of a respective sewingmachine be inexact alinement with the center of the pivotal connection. Under these conditions it makes no difference at what corresponding angles the two machines are or of what type machine is used the centers of the blades will be central of the respective end buttonholes at the time of cut. This condition insures the uniformity of the buttonhole and its proper angle and distance from the center of the collar. This particular arrangement, coupled with a centralizing device, enables me to locate the collar so that it is exactly central between the two proposed end buttonholes at the time of cut. This absolutely locates the end buttonholes exactly the same distance each side the center buttonhole.

Inasmuch as this machine is adapted for sewing cuffs, collars, shirt-bands, or other articles requiring a buttonhole at both ends and in order to avoidconfusion, I shall mention collars in the claims, it being distinctly understood that in the use of this term it contemplates all articles capable of being operated upon and is in no wise a limitation, and while I have not shown the machines so located it is evident they may be turned so as to cut and stitch buttonholes transverse of the length of the collar.
