EMBROIDERY-MACHINE.

To all whom it may concern:

Be it known that l, FRANK MAnsciiALnK,

a subject of the King of Hungary, residing the size of the article varying according to'l the size 'of the frame whichmay be used, and is therefore not intended for use in the making of embroidery 10 and 12 yards long, as is the ordinary Swiss machine.

The. object of the invention is the provi'- sion of a machine of the. character described by means of which both halves ot' the Work can be completed at' the same time and by means et' which a great many articles of the' same kind maybe made at-the same time.

A further vobject of the invention is the provision ofv a'n improved-machine of the character described in which the Work franies''are supported transversely of the length of the machine. t n

A further object of the invention is the provision of an improved machine of-'the and and borers'lshiftable into and out -of the work may also beshifted in Atransverse planes relatively to said work instead of the work and borers, as in' my contemporaneously pending application, Serial No. 833,595, filed Aprilf22, 1914. g

A further object of the invention is the provision of an-improved machine o f the character described, comprising a series of independently supported work frames and a series of sets of yneedles and borers so organized that eachl set may consist of at least two needles and two borers for each frame whereby both halves off/the work may be completed at .the same time,

l A further object of the invention is thev provision of an improved machine of the character described iiiwhich the work frames are supported.v in two series, one

i' above 4the other,i transversely of tlie chine, and the needles and borers are likebeing shifted relatively to 'the needles Specification oi Letters Patent. Patented Sept, 2S, 1915. Application filed March 26, 1914. iSerialiNo. 8 17,283. i

' wise supported in two series one above the other, each Series consisting'of a set of needles and a set of borers, whereby both halves of the work can be completed at the same tiine," and which borers and needles are automatically.shifted into and out of the vwork and also manuallyl shiftable in transverse planes relatively to the work.

In' the ordinary Swiss embroidery machine, the. embroidery fra-me is usually twelve yards long and is moved up anddown and endwise by means of a panto graph, while the needles and borers are simply .shiftable into'and out ot the work. In the present improvement, however, 'the Work frames are located transversely of the -machine and maybe of any desired size according to the work to be done and it the machine is twelve yards 4long it will accommodate a series of work frames one set at the top and the other set' at the bottomof the machine, preferably one above the other, whereby a large number ot articles of similar character may be made at the. same time, and in the present instance instead 'oi' shifting the framesrelatively to the needles and borers the latter are shifted, in addition to their ordinary movement in and out of the work, in transverse planes relatively to the work, and inthe presentl organization I am able t'o provide two needles and two borers tor simultaneously working on each frame, whereby, as hereinbefore state'dyboth halves of a piece of lwork can be completed at the same time, whereas' in prior machines of .this general charactery only one needle could work at a time on an article. In short, in the present `improvement each work frame has its own'needles and borers and each set of needles and borers is `located above another setthereoi'.

In the drawings accompanying and forming part of this specification, AFigure 1 clearly toillustrate the improvement; Fig.'

4 is an enlarged detail view, partly in sec` tion, of the left-hand en d of thermachin'e shown in l, taken at the right of the pantog'raph; Fig. 5 'is a detail-view of a needle and borer bar and the carrying machinefwith certain parts omitted more -deemed sufiicient.

shafts therefor, this View being taken on line 5.-5, Fig. 4; Fig. (3 is a sectional plan View taken on line 6 6, Fig. 1; Fig. 7 is an enlarged, partly sectional, view illustrating a part of the mechanism shown in Fig. 4, and this view is taken on line 7 7, Fig. 3; and FigsS and S) are detail views illustrating in part the-connection Abetween the,`

pantograph lever system and. the parts which 'it controls.

Similar characters of reference indicate corresponding parts in the several figures of the drawings.

. The framework ofthe machine in the present improvement consists of four uprights, one at each corner of the machine,

and each of these uprights, (see Fig. 6),

consists of a substantially U-shaped post 2. These four U-shaped uprights are connected at their tops by lengthwise extending beams 3 and crosswise extending beams 4, and are similarly connected at their bottoms' by lengthwise extending beams and crosswise extending beams v7, thus forming a rectangular frame for the support of the various mechanisms.

The wor/.3 or embroidery frames-Cari ried by the framework described is a series of work frames made up of two sets, 8 and 9, one set supported above the other transversely of the length of the machine, and the frames of each set are suitably spaced apart for the positioning and operation of the 1) onefor ea'ch. work frame. Rigidly secured to each lengthwise extending supporting bar l l I A 10 at tne rear of the frames is a series of lugs 19, one for each frame, each being located at the-'rear side thereof and against which .the bottom of the frame is clamped.

For this purpose, each angle iron formed bar.

1o carries a sliding bar 13l having a series of rigidly connected lugs 14 movable therewith and one located in position at the front of each frame, this lug being shiftable, as stated. with the sliding'bar whereby it may be moved into engagement with or from the frame to release the same to permit the frame vto be slid out of its guides. For shifting this shiftable lug each shiftahle bar 1? is provided at its forward end with a rack in engagement with a pinion. the operation of which will move the shifmble bar and release or clamp the arms of the frames,

s sllitable coil spring 16 being used to draw the shiftable lugs into engagement with `the fixed lugs, (see Fig. 1). The pinions for the upper set'of fralnes and for the lower set of frames a re connected kby links 18 and 19 and a connecting rod 2 0, and on grasping the connect-ing rodand moving the shiftable bars the frames may be all simultaneously released'or engaged. l i

The nec/(Ho (mtl borer mechrmfsmr-Jlwo series of needles and borers and 31 are provided, one series above the other, and each series consists o'f a set of needles and a set of borers, two needles and two borers 33 for each frame, so that two needles and two borers will always be working on each upper frame and a similar number of im-Kv Yplements on each lower frame.

Extending lengthwise of the machine are two hollow

parallel bearings

34, 35, which are supported for movement towar'd and away from each other and'each of which carries at each end a pair of rollers 3G, (see Figs. 4, 6 and 7), and these rollers are mounted on a supporting track 40,'each having at its ends a pair of antifriction rollers 37 located in a U-shaped guideway 38 of theupright posts 2. Extending through each of these hollow .hearings is a pair of

shafts

41, 42, and these shafts are .supported for lengthwise movement relatively to said bearing.A Carried by each of the hollow bearings is a series of upwardly and downwardly 'extending U-shaped fixed arms 43 integrally formed withsuch bearings, the U-shaped arms,corresponding in number with the number of work frames` and these U-shaped arms at their lower and upper ends respectively open into enlarged portions 44 of the hollow bearings. These U-shaped arms form the guiding means for the needle and borer bars, (see for instance Fig. 3 and Fig. Each of these U-shaped arms carries a needle bar and a borer bar` one of each set carrying. a needle and the other a borer at its end, and the juxtaposed ends of the upper and lower needle and borer hars are secured to the shafts 41 auth-12 so as to shift therewith when these shafts are moved lengthwise, the U-shaped supporting arms being of sufficient depth to permit this shifting, and whenthe shafts are shifted .lengthwise the needles andborers are shifted into and out of the work in the usual manner. The borers of the entire series at one side ofthe frames are connected to one shaft, as 4:2, while the needles of the entire series at the same side iare all connected to the other shaft, as 41. These shafts, which are slidinglyv mounted in the hollow bearings, project beyond the ends of such hollow bearings and the squared and shouldered ends 45 of the four shafts ateach end of the machine arel mounted in a'slide which is in the a link'210 which supports it .between its ends, and this link 210 is in turn pivotally connected at its lower end between the converging ends of the supporting brackets. The link 209 extends back and is pivotally connected to an adjustable vblock scttable in anv desired fixed position ina vertical slot 211 carried b v an upright bracket 212, (see Figs. 1 and 2), and to this bracket, which is forked at its lower end for this purpose, is secured a' rack member having two sets of

teeth

213 and 214, (see Fig. 8), one at each side thereof, and these rack teeth are in engagement with a pairof pinions 215 and 216 mounted on short

upright shafts

217 and 218 carrying

similar pinions

219 and 220 at their lower ends, (see Figs. 2 and 4). One of these shafts is shorter than the other and the

pinions

219 and 220 mesh with a pair of

racks

221 and 222 respectively, (see Figs. 2 and 4), which racks are formed with dovetail guiding portions 223 adapted to slide in similarly formed guides 224, which guides 4are formed as part of a bracket (see Fig. 4), secured to that U-shaped cross member 90 which is located at the lefthand end of the .machine This guide. bracket also has bearings for 'the two upright short shafts. This bracket 225 has a forwardly extending portion 225 on which is secured a horizontal slideway 230, (see Fig. 4), in which the double rack hereinbefore described can move a predetermined distance back and forth. This guideway230 supports a pair of upwardly converging arms 231 and 232 which terminate in a pair of slotted racks 233 and 234, which racks are also supported at their rear sides by abracket 235 which is secured at its lower end to that U-sha'ped member 9.0 which is at the left-hand end of the machine. Thus, as stated, thedouble faced

rack

213, 214, -which is secured to the lower end of the bracket 212 which is fixedly but adjustably connected to the inner end of the lever or link '209 of the pantogra-ph;\may have a sufficient movement in its/.slideway 230 to rotate the pinions 2146and 217 and thus shift the racks f221 and 222 to move the hollow bearings lat'- erally in the manner about to be described.

', The two .

racks

221 and 222 are secured to bracket arms 226 and 227, one for each rack,

and the bracket arm 226 is secured to one of.

l of, and therefore whenTlv these two racks are shifted by\means of their pinions, which are shifted by" the double-faced rack hereinbefore described, they will movethe hollow .cross members 4G are reciprocable in the U- shaped portions of the cross members 90, while at the Sametime the shafts may slide laterally when the hollow bearings are shifted toward or from each other on the tracks 40 in the guideways formedin the-cross members 4G, which are carried within the U- shaped portions of the cross members 90, so that the shafts thus have two movements, a lengthwise movement and a crosswise movement, the lengthwise movement being within the hollo'w bearings andthe crosswise movement being with the hollow bearings.

g From the foregoing it will therefore be seen that when the pantograph is manipulated by the operator in a vertical direction it will, through the medium of the lever system and the fixed but adjustable connection of the lever 209 with the vertical slot 211, raise and lower the cross beams 90 and-all the parts connected therewith, thus raising and lowering the hollow bearings and therewith the shayfts 41 and 42 and the needle and borer bars, so that the needles and borers may be shifted in a vertical plane, the counterbalancing weight 93 hereinbefore described balancingv these parts in such a. manner as to permit this.

As hereinbefore stated, the double-

faced rack

213, 214 may have a movement through the medium of the pantograph in its slide 230 to rotate the pinions and thereby the

racks

221 and 222 so as to move the hollow bearings laterally or toward and from each other and thereby give the needles and borersa movement transversely of their vertical movement, and this is accomplished by providing an adjustable but relatively fixed slide 240, (see Figs. 2 and 4), adjustable up and down on the slotted racks'233 and 234 but fixed at any desired point relatively thereto by wing nuts 241, and this slide has a dovetail guideway therein in which is located a block 245 secured to or integral with the bracket 212, so that when the pantograph 200 is swung transversely of its up-and-down movement it will move the member 212 in this guide 240 and thus shift the double-faced rack at its lower end in the slideway 230 and thereby operate the

pinions

216 and 217 in the'manner hereinbefore r described and so 4shift the racks 221 and 222 i tending across the machine. In other words',

there is one of these bars 46 at the rear end and one at the forward end of the machine for supporting the series of four shafts. Each of these bars 46 is provided at its ends, at its upper and lower sides, with rollers 47,

` (see Figs. 6 and'7), projecting into U-shaped vguides 48 of shiftable upright members 49,

which membersy are provided at their tops and bottoms with rollers 50 mounted on tracks l'carried by the U-shaped posts 2 of 'the framework, '(seel `igs. 4, 6 and 7).

DWI/ving madam/Sm for the nccdles,aml 150mm-T his comprises, (see Figs. 1 .and 2) al fast pulley 60 and a loose pulley 61 mounted on astub shaft 62, (see IFig. 1), and driven by `any suitable source of power. Secured to the fast pulley 60-is an eccentric or cam 63. In engagement with this eccentric 63 is a cam. roller 64, which cam roller is carried at the lower end of an upright rod 65 mounted in a suitable bracket 66 secured to the framework and -between the upper and lowerbearings 67 and 68 of which bracket a coil spring 69' is secured to the rod, by'means of which the camv roller is maintained in engagement with the eccentric. Secured to this upright rod is a crosswise extending rod 70, and to each end of this rod 7 0l is attached a link 71, theoppol site end of which is pivotally connected to the frame member' 49 hereinbefore referred' to at its lower end, the upper end of each frame member being similarly connected to a link 72 the opposite end of4 which connected toa connecting rod 73, the lower end ofwhich is secured to the rod 70, whereby on the up and down movement ofthe cam roller the two frame members 49 at the lefthand end of the machine will be moved back and forward on its tvacks, andas it is necessary that the similar frame members at the opposite end of the machine 'be moved simulf taneously a connecting' mechanism is provided for thisl purpose, this consisting at the bottom of the machine of a link 75 connected to aA bell crank lever 76, which in turn is connected by a rod or lever 77 with a bell crank 78 at the opposite end of the machine,

-' which in turn is similarly connected by

links

79 and 80 throughthe medium of a rod or shaft 81, and at the 'top of the machine -the link 72 at the forward end and the similar link 7 2'- atthe rear end are connected by a somewhat similar connecting mechanism comprising levers 82, 82', bell cranks 83,

83 and connecting lever or rod 84, the links 72' and 80 at therear end of the machine being in turn connected by a rod or lever 73', whereby both frames 49,"that is oneat the forward end and the other at the rear end, at each side of the machine will be shifted back and forward simultaneously to slidethe shafts 41 and' 42 in their hollow bearings and thereby act-nate the needlesand.

borers tocarry them into and 'out of the work.

If it is desired to stop the machinel atany time when the cam rolleror eccentric is at the highest point, at which time of course the spring is under its greatest tension, a

lever 85 having a forked end straddling the cam -carrying rod and projecting under the spring is provided. This lever 'carries a pawl 86 in engagement with a ratchet 87.

On manipulating this lever the spring can be held at its highest point and thus free of engagement with the eccentric or cam.

vMechowl/sm for moving tbemiedles and borers up and clown and Zate?aZZg/.-The two cross members 46 which support the ends ofv y the sliding shafts at the front and rear of the machine are carried in turn by a pair ofv whichlikewise extend across the machine,

(see Figs. 6 and 7),'is provided at its opposite ends, at the front side, with rollers 91 projecting into Ushaped guides 9270i? the U-shaped posts 2, and to each of these U- shaped members is rigidly securedv the supporting track '40 hereinbefore described Iwhich supports the ends of the two hollow bearings carryingthe two sets of

shafts

41 and 42. vided at each end with a balancing weight 93, the cable 94 of which extends overa pulley 95, and by this means the entire system of needles and borers is properly counterbalanced.

llhe upand down movement of the U- s shaped supports 90, and therefore of the entire system of needles and borers is obtained through the medium of a pantograph 200, which may be of the usual construction. This pantograph is supported by a pair of brackets 2 02, which brackets are secured to the upright posts at the left-hand end of the machine and converge toward each other, (see Fig. 3), and each of these brackets comprises a-pair of

arms

204 and 205, each of the rrms 205 having a bea-ring for the shaft of tle pulley 95 and a support for the bell crank 83. The pantograph lever system is suitably counter-balanced by means of a weight 203 extending over a'guide pulley ,1 203', and which pulley is carried by' an ad'- 1 .justable bearing'206 lmounted on a standard 207'.' The lever system Vof the panto,g"raplt includes -a pair of links'208 and 209, the" 1 link208 being pivotallylconnected between the converging endsofthe two brackets, while the link -209 is pivotally connected to The supporting track 40 is pro-y magari -pantographlias a certain limited operation,

and if it is desired to operate say at the top or the bottoni of the board or pattern the slide 240 is,by means of itsjing nuts, adjusted farther up or farther dow-nas the case may be. i

The shuffle 7w('hrm.s'm.-Sitable shuttle niechanism provided for each` set of needles and boi-ers, and as each is a duplicate of the others a description of one is suiiicient. The shuttle 250 for each needle is carried in a raeeway Q51. at the rear. of its frame. This raeewayis linked by a pair of pivoted links or levers2 2 arid to one face of a U-shaped arm, and by means of a pair of

segmental brackets

254 and 255 likewise carried b v the U-shaped arm and suitable. pins, the raceway may be swung into or out of position, thereby permitting` ready removal of the work frames. Cai'- ried by the upper link is a, segmentally formed track 250, in which is located a chain 257, and to this chain, by means of a linkage s vsteni the shuttle is connected, and this chain is in turn connected at its lowerend to a member 259, which is pivoted to the U-shaped arm, and this arm is provided at 'its forward end witha slot 260 into which projects a pin` 261 'projecting through a slot of the U-shaped arm, and this pin is connected with the needle bar, so that when the needle moves back and forth into or out of the work. the pin operates the lever'or link and so shifts the chain in its' segmental 'gnideway or raceway and thereby moves the shuttle up and down, the

different positions of the same shuttle being shown in Fig. 4. it will thus be seen that by this mechanism, when the needles are moved vertically or horizontally through the means hereinbefore described the entire shuttle mechanism moves therewith. Connected-with this levei or link i259 is a. spring presser 202 for pressing the-work away from the needles when it is withdrawn. A spool 270 is carried by each uiriglit, and the thread is led over an idler 2 l and turned around the same once, and

from thence it passes to a take-up device 272 ithe inner end of which is likewise connected with the chain, and this take -up device passes tlirougli a slot of the upper link 252.

As hereinbefore. stated` the shuttle mechanism for each set of needles is the same., and

this is trne of the shuttle mechanism for the upper sets of needles, but the shuttle mechanismv for the ,lower sets of needles, while operating the same, are slightly different in vthe'detailed construction, but it is deemed unnecessary to further describethe same.

F or braking the roll once, and each idler roll has a braking a rotatable shaft 303.

series of U-sliapcd threads, the thread, i.hereinbeforestated, passes around `the idler ing at its lower end arack 301, each ofv which is engaged by a pinion 302 carried by This shaft is provided with a pinion 304 suitably supported, and which pinion is engaged by another pinion 305 carried by a hand wheel 30G, the manipulation of which will operate all of the braking mechanisms to increase or decrease the tension on the idler rolls and thereby the tension on the threads. Each 4rod 300 has frictional engagement with its idler roll, for which purpose each rod is shown with its upper or lower end, as the ease may be, bent into engagement with theI roll. it therefore follows that, by reason of the-inclination of this iod adjacent to the-engagement. thereof with its roll, the manipulation of the rod up or down places greateifvor lesstension, as desired, upon the roll. i

It will be understood that the various details may be changed without departing from the spirit and scope of this improvement, the present embodiment of the machine illustrating one form of mechanism which may be used for carrying out the. invention, and that other meansinay be used in connection` with the pantograph and the power for actuating the needles and boi-ers in the manner herein shown and described. and thereforel applicant does not limit himseliZ to the specific mechanism herein shown and ldescribed for accomplishing this purpose.
