Application filed lngif' 24, 1889. Serial No. $21,862. (Model.)
To all whom it may concern:
Be it known that I, JOSEPH P. HALLEN- BECK, a citizen of the United States, residing in the city of New York, in the State of New York, have invented certain new and useful Improvements in Button-Sewing Machines, of which the following is a specification, reference being had to the accompanying drawings, in which similar parts are marked by like letters in the differentviews, and the directions in which some of the parts move are indicated by adj aeent arrows.
This invention relates to machines for sewing to clothing and other articles or fabrics buttons having perforations or eyes through them from side to side; but some parts of the invention are applicable to machines for sewing on buttons having shank-eyes.
The general objects of this invention are to furnish a sewing-machine with excellent mechanism for holding and intermittingly moving a button having four eyes and presenting the eyes in succession to the needle to sew on. the button by stitches from eye to eye progressively around the circuit of the eyes, to provide such mechanism with adj usting devices whereby buttons having eyes at widely different distances apart can be thus sewed on, to provide such mechanism with adj usting devices whereby buttons having four eyes or two eyes can be sewed on by stitches extending to and fro between two opposite eyes and across the center of the button, to produce a button holder and carrier having superior means for receiving and holding such buttons and applying them to the fabric in the sewing-machine, to furnish the button holder and carrier with adjustable devices for holding and carrying buttons of very different sizes, to provide the button-carrying mechanism with excellent means for antomatically securing the sewing on of a button by a certain predetermined number of stitches, to provide such means with adjusting devices whereby the sewing on of buttons by certain different numbers of stitches can be secured, to provide means for automatically stopping the sewing-machine when the button-carrier shall have moved a certain predetermined number of steps, and to provide a device whereby the machine'can be conveniently started and kept in motion. Other objects of the invention are hereinafter set forth. These objects are attained by the mechanism illustrated in the accompanying drawings, in which Figure 1 represents in side elevation. and partly in section a button-sewing machine embodying one form of this invention, the section being mainly at about the line .2 z in Fig. 2, which is a plan of the under side of the same machine. Fig. 3 shows a section of a portion of the bed-plate ofthe same machine at the said line .2 z and an elevation of some parts of the mechanism, as seen in the direction of the arrow '1 in Fig. 2. Fig. i represents a section of the lower portion of the same machine at the line or a," in Fi 2 and an elevation of some parts as viewed in the direction pointed by the arrow 10, and Fig. 4 is a plan' and partial section of parts at the line 20 10 in Fig. l. Fig. 5 shows a section of the lower-portion of the same machine at the line c o in Fig. 2 and an elevation of some parts as seen in the direction of the arrow u, and Fig. 5 is a plan and partial section of parts at the line ru 10 in Fig. 5. Figs. 6, 7, and 8 represent some detached parts of the mechanism shown in 2. Fig. 9 shows in plan and on a larger scale the button hold ing and carrying mechanism represented in elevation in Fig. 1, and Fig. 10 shows the same mechanism in partial section at the line i t in Fig. 9. Fig. 11 is a plan of the under side of a part of the button-holder shown in Figs. 9 and 10; and Figs. 12, 12, and 13 are isometrical representations of some detached parts of the same button-holder. Figs. let. 15, 16, 17, 18, 19, 20, 21, and 22 are isometrical illustrations of detached parts of the same button holding and carrying mechanism shown in Figs. 9 and 10. I
This invention is mainly applicable to various kinds of well-known sewing-machines. The drawings illustrate it applied to a sewingmachine manufactured by the Singer Manufacturing Company. Of that machine, A represents the bed-plate; A, the overhanging arm; B, the reyoluble driving-shaft; B, the needle-bar, which is depressed and elevated at each revolution of said drivingshaft; C, the shaft which carries the hooked shuttle and is oscillated at each revolution of the driving-shaft by the intervening crank B connecting-rod B rock-shaft 0, having the arms 0 C and the arm (3 on the shaft 0 and engaging the arm 0 and O is the feed-actuatin g rock-shaft having an arm 0, connected with the driving-shaft by the rod 13 and eccentric B As a means for carrying a button-holder holding a button, as Y, Figs. 9 and 10, having four eyes 1 2 3 4, in a circuit, so as to present each of the eyes in succession to the needle to of the sewing-machine, the button-holder is secured to a primary slide D, having a socket b, Fig. 16, with a crank-pin or eccentric E, fitting in said socket and secured to a revoluble shaft or carrier F, mounted to rotate in a fixed position or socket b, Fig. 10,, and connected to the. driving mechanism of the sewing-machine by devices which cause the rotation of said crank-pin or eccentric by steps of equal length and equal in number to the number of eyes in the button. The slide D is also provided or furnished with a secondary slide G, having a guideway, as c c, for said primary slide and furnished with means for insuring the movement of said secondary slide bodily and equally in all its parts to and fro laterally to said primary slide and said guideway, so that the intermittent rotation of said cranlcpin or eccentric E causes the positive crank-pin or eccentric.
step-by-step movement of every part of said primary slide and attached button-holder in a true circle equal in diameter to the diameter of the circle described by the center of said In carrying out this part of my invention any suitable known means may be used to secure the movement of said secondary slide bodily to and fro laterally to said primary slide in a course perpendicular or somewhat inclined to said primary slide or in an arc of a circle or a curved course.
As a superior means for accurately guiding the secondary slide G and the primary slide D, with its'attached button-holder, when actuated by theeccentric E, fitting in the socket b in theprimary slide, I provide a stationary base-plate H, Figs. 9, 10, and 14, which supports the two slides and has a guideway (2 cl, Fig. 14, in which fit and slide wings c, Fig. 15, on the slide G, which has guides c c, in which the primary slide D fits and is moved to and fro by the eccentric E, having its carrier F mounted to rotate in and 011 said baseplate.
To provide means for properly presenting to the needle of the sewing-machine buttons having their eyes in circles of different diameters or at various distances apart, I combine with the primary slide and its attached button-holder a laterally-movable guideway for the primary slide, means to direct the lateral movements of said guideway, an eccentric fitting in a socket in the primary slide, a revoluble support which carries the eccentric and revolves it step by step, and means by which the eccentric can be secured to its said support at different distances from its axis of revolution.
To provide means for securing the eccentric upon its carrier at different distances from its axis of revolution, I form the eccentricE, Figs. 10, 18, and 19, and its carrier F, Figs. 10, 14, and 17, one with a radial groove f and the other with a corresponding tongue f, adapted to fit and slide in said groove, and have through the eccentric a suitable perforation f and a clampingbolt I, extending through the perforation f and engaging with the carrier F, whereby the eccentric can be secured to the carrier at Whatever position it shall be set thereon.
To facilitate the adjustment of the eccentric E on its carrier F, there is introduced upon the eccentric a cap-piece I, Figs. 9, 10, and 20, having a central perforation g, through which the clamping-bolt I extends, and a camslot h, into which extends a pin 1', Figs. 10 and- 19, fast on the eccentric, so that upon loosening the clamping-bolt and turning the cappiece I to or fro uponthe eccentric and about the bolt I as a pivot the eccentric will he slid radially along the ways ff by the cam-slot h and pin 11 in or out upon the carrier F to different distances from its axis of rotation, and can be there clamped fast with the cap-piece I by tightening said clamping-bolt.
To further facilitate the adjustment of the eccentric upon its carrier, I form in the periphery of the carrier F a recess j, Figs. 14 and 17, and also form in the stationary support II of the carrier a slot j, so arranged that when the carrier is turned into a certain position its recess j will register with or be as an extension of the slot j, as shown in Fig. 14. I also have a stop-bolt J, Fig. 22, which can then be inserted through the slot j into the recess j, so as to prevent the turning of the carrier F while the eccentric E is being readjusted and clamped fast thereon, as above described, and so that the bolt J can be withdrawn from the recess j to let the carrier revolve.
As regards the above-described parts of my invention, the button-holder attached to the slide D may be of any suitable known kind.
To provide a button-sewing machine with, improved means for conveniently receiving,
centering, and securely holding and carrying buttons having eyes through them, I have a fabric-presser K, Figs. 9 and 10, so secured to a suitable carrier, as D, that said fabricpresser can be freely elevated and depressed and retained upon the fabric, and have the foot of said presser formed with a recess e and provided at the sides and end of that recess with lateral guide-bearings is, Fig. 9, so as to just permit a button to be insertededgewise between them and thereby centered, said lateral bearings being furnished with thin lips Z, projecting inward at the lower edges of the bearings. Ialso have a somewhat elastic button-presser L, attached at one end to the ICC IIO
shank of the fabric-presser K and having its foot formed with a recess c and shaped and arranged so as to permit the button to be easily pressed in between it and the lips Z and the edge-bearings 7r, and so as to then press down upon the inserted button outside of the circuit of its eyes, and thereby securely hold the button when such button-holder is elevated to permit the insertion and removal of buttons and when depressed upon the fabric X, as in Fig. 10, while sewing on a button.
Any suitable known means can be used to secure the button-holder to its carrier and to elevate and depress the sameas, for instance, such as is shown in Figs. 1, 9, and 10, wherein a part K, to which the part K is firmly attached, is hinged at cl to a standard (Z on a part D, which is firmly attached to the carrier D, and has a vertically-adjustable screw post (1 extending upward loosely through an aperture in the part K and surrounded by a spring d", compressed between the parts D and K, and a cam-lever d is mounted on the post (i over the part K, which is pressed upward against the cam-lever by the spring (1*. When the cam-lever d is turned into its position in Figs. 9 and 10, it presses the button-holder down upon the fabric X, and thereby clamps the fabric upon the thin plate D which is attached to the part D and extends over and slides upon the cloth-plate a, Fig. 10, and has an aperture d, Fig. 21, about the needle-hole a and of greater size than the circle of the eyes of the buttons to be sewed on. "When the camlever d is turned into another position, the spring CP'GlGVELtGS the button-holder in the course of the broken line 6 in Fig. to permit the free removal from the button-holder of a button sewed to a fabric and the easy insertion of another button into the buttonholder.
for example, by having the seat portion Z of the part L rest on the ends of four screws 0, which fit in and are adjustable through screwsockets 0 Fig. 12, through the part Kand a clamp-screw c havingits head bearing on the part L and its shank extending through a perforation a, Fig. 13, in that part, and screwing into a screw-socket c in the part K.
hen the button-holder is to be used to hold buttons of equal-diameters,thebearings for the edge of the button and the lips Z for supporting the under side of its rim may all be on one integral stock.
To make the button-holder capable of receiving and holding buttons of very different diameters, I provide three sub-feet m, Fig. 12, each with a lateral bearing 70 and lip Z, and with a tongue 71, having therein a screwsocket n and extending upward and fitting into one of three longer slots of, Fig. 12, arranged as at three sides of a square through the plate of the fabric-presser K, and each furnished with a clamp-screw n fitting in the screw-sooket a, and the under side of the head of the screw bearing upon said slotted plate, substantially as indicated by Figs. 9 and 10, so that thereby the three sub-feet m can be readily adjusted and firmly secured to said plate with their guide-bearings 7c at various distances from a commoncenter. The lips Z may be rigid on the sub-feet m, or may consist of the free projecting ends of thin sheet springs extending under and along the sub-feet and united to the heels thereof, as indicated by the lines at m in Figs. 10 and 12?. By the above-described adj ustability of the button-holder it is adapted to receive and hold buttons of equal diameters and diderent thicknesses, and buttons of equal thicknesses and different diameters, and buttons of different diameters and different thicknesses.
As regards the above-described parts of my invention, any suitable-known means can be used to revolve the carrier F of the eccentric E step by step in concord with the movements of the needle-carrier of the sewing-machine.
As an improved means for that purpose, I
have fast on the carrier F a bevel-gear F, Figs. 10, 1, and 2, engaging with a bevel-gear M, mounted to freely rotate upon the oscillating shaft 0, supported by fixed bearings y, and I have fast on the gear M a ratchet M, Figs. 2, 4, and 8, furnished with a driving-pawl N and pawl-carrier N, mounted to too vibrate on shaft 0, and. having an arm N jointed to a rod N which is jointed to an arm 0 fast on the rock-shaft O, which is mounted on the bearings 03 and has an arm 0, con nected to the driving-shaft B by the eccentric B and connecting-rod 13, whereby the carrier F and eccentric E will be turned a step at each revolution of said driving-shaft.
To render the mechanism capable of sewing on buttons having four eyes by stitches from eye to eye in succession around the circuit of the eyes, and also capable of sewing on buttons by stitches extending across the center of the button between two opposite eyes, the gear M may have teeth of a number multiple of the number of teeth in the gear F, and the number of teeth in the ratchet M maybe equal to or a multiple of the product of the number four and the ratio of the numbers of teeth in the two gears as, for example, when the number of teeth in the gear M is eighteen and in the gear F is nine the ratio is two, which multiplied by four gives the product eight as a proper number of teeth for said ratchet; also, the rod N may be jointed to the point 0 to the point 0. WVith this construction when the rod N is jointed at 0 to the arm 0 as shown by full lines in Fig. 4, the pawl N will be moved by the arm so as to turn the ratchet M. a step equal to only one of its eight teeth, and thereby turn the gear F, shaft F, and eccentric E through only onefourth of a revolution, as required in sewing on four-eyed buttons from eye to eye in a circuit. When the rod N is jointed by the pivot-coupling P, or its equivalent, to the arm 0? at 0, Fig. 4, the pawl N will be moved by each rocking movement of said arm so far as to turn the ratchet M a step equal to two of its eight teeth, and thereby turn the gear M through one-fourth of a revolution and the gear F, carrier F, and eccentric E one-half of a revolution, as when stitching across the center of a button through and between its opposite eyes.
M is a collar fastened adj ustably to the shaft 0 to retain the gear M in proper engagement with the gear F and to keep the driving pawl N and its carrier N in proper relation to the ratchet M, and M is an adjustable friction-brake bearing against the sleeve of said ratchet to secure its accurate movement by said driving-pawl and to prevent the movement of the ratchet by the shaft which supports'it.
Q is a friction-disk fast on the driving-shaft B, and Q is a corresponding friction-disk, grooved to receive a driving belt or b'and'and loose upon and slightly movable along that shaft. R is a shipper mounted on a'stationary pivot at p and arranged so that upon moving it in the direction of the arrows to in Fig; 1 the disk Q while revolving will be pressed by the shipper against the disk Q to rotate it, 4
and thereby the shaft B, and so that upon moving the shipper in the opposite direction it will release the disk Q from the disk Q to let it and the shaft 13 stop.
R is a brake united to the shipper R and arranged so that when the shipper releases the disk Q from the disk Q the brake will then bear against a projecting part 19 of the disk Q, as shown in Fig. 1, to stop the machine, and so that when the shipper presses the disk Q against the disk Q the brake R will be removed a little from the projecting part 19 of the latter disk, as in Fig. 2.
S is a rod jointed at 132 to the shipperR and mounted to slide to and fro lengthwise in bearings through stationary brackets or lugs 11. 10 The rod S has a collar '8 fastened thereon, and is furnished with a springs which is compressed between the collar S and lug 10 so as to constantly tend to move the rod S in the direction of the arrow Q2 and thereby move the shipper B, so as to release.
the disk Q from the disk Q and apply the brake R to the former disk. Another collar S is fast on the rod S and has lugs q, between which is a pin g on the short arm of a lever T, which is pivoted at to a bracket g on the bed-plate A, so that by pressing down the long arm of that lever, from its position in Fig. 1 to its position in Fig. 3 the rod S will be moved in the direction of the arrow 0 Fig. 1, in opposition to the pressure of the spring S and will move the shipper so as to press the disk Q againstthe disk Q and remove the brake R from the latter disk, and thereby start the machine and keep it in motion.
To avoid all necessity for continuously.
pressing down the long arm of the lever T while the machine is in operation, and to provide means for automatically stopping the machine when it has made a certain predetermined number of stitches in sewing on a button, I provide a revoluble thrust-bearing U, Figs. 1, 2, 3, 6, and 7, for the slide-rod S and the follower U on said rod, and have on said revoluble bearing a ratchet U Fig. 5, furnished with a driving-pawl V and its carrier V, pivoted at r to'a connecting-rod W, which is jointed to an arm 0 on the rockshaft 0, from which the button-feeding1nechanism is actuated, so that for each step movement of the button-carrier the thrust-bearing U will be turned .a step. I also have the parts U U formed with abrupt ledges s s and with contiguous bearing surfaces 3 3 whereby during a large portion of each revolution of the thrust-bearing U the slide-rod S is held, in opposition to the pressure of the springS in the position to keep the loose driving-disk step rotation of the bearing U its ledge 8 passes the corresponding part 8 of the follower U the rod S and shipper R will be instantly moved by the spring S so as to release the disk Q from the disk Q and apply the brake R to the latter disk, and thereby stop the machine. When the machine thus automatically stops in using it, the sewing on of a button is usually completed, and the sewed-on button should be removed from the button-holder and another button inserted in the holder, and therebydepressed and held in proper place on the fabric. By then pulling down the long armof the lever T; which may be connected with a foot-lever for that purpose, the slide-rod S will be moved so as to start the machine, as above described, and upon then holding down that lever until the button-carrier shall have moved a few steps the thrust-bearing U will have turned so as to bring its surface s opposite to the surface 3 of the follower, at which time the lever T should be released to let the follower bear against the thrust-bearing until in its rotation its ledge 3 just passes the ledge s of the follower and the machine then stops.
The ratchet U Fig. 5, has a suflicient number of teeth to permit the mechanism to sew on a four-eyed button by stitches from eye to eye in a circuit repeatedly while the ratchet and the thrust-bearing U revolve 0nce.'
To make the mechanism capable of moving the button-holder different numbers of steps during a rotation of said thrust-bearng, as is generally desirable and important in using the mechanism to sew on buttons through ditferent numbers of eyes, I joint the pawl-operating rod \V to the arm 0 of the rock-shaft O by a pivot-coupling'X, Figs. 5 and 5=,'which is adjustable along that arm to different distances from the rock-shaft, whereby the pawl V canbe caused to revolve the ratchet U and thrust-bearing U by steps each equal in angular extent or degree to that of either one, two, ormore teeth of the ratchet at each to-and-fro movement of said rockshaft.
S is a collar adj ustably secured to the rod S to variously limit the movements of that red in the direction of the arrow The pawl-carrier V is mounted loosely on the rod S, and between that pawl-carrier and the bracket a is a loose sleeve V on said rod. The thrust-bearing U and ratchet U are united by a sleeve U which is loose on the rod S and is furnished with an adjustable friction-bearing V to insure more accurate stepby-step movements of the ratchet by its driving-pawl.
