To all whom it may concern:

Be it known thatI, itrLLrArr-F. DREXLER, Jr., a citizen of the United States, residing at Morton, in the county of Tazewell and State of Illinois, have invented certainnew and useful Improvements in VVire-F-abric Machines; and I do hereby declare that thefol lowing is a full, clear, and exact description of the invention, which will enable othersslrilled in-the art to whichit appertainsto make and use the same. I

This invention has referenceto machines for the manufactureof wire fence fabric and relates particularly to an improvement to that type of fence Weaving machines wherein the twisters for intertwisting the wires which form the fabric are revolubly mounted on a twister support adapted to travel in a con tinuous or it. 7

One of the obj eets whichI have in view is a support adapted to travel in a continuous orbit on which is mounted a series of rows of forming blocks ordics adapted to receive stay blanks asthe said support-is revolved and to shapethe said stay blanlrsintothe form in which the said stays will appear when woven with a series of longitudinal stringer or strand wires, and to means for delivering the formed stays to a series of rows of twisters revolubly mounted in a support adapted to travel in a continuous orbit.

A further object of the invention is a revoluble drum on which is pivotally mounted a series of longitudinal and circumferential rows of forming blocks or dies and to-means for oscillating the forming blocks or dies in each row in one direction during a'partial rotation of said-drum and for returning the same to their normal positions during-the further rotation of said drum.

A further object of the invention consists in means for feeding and simultaneously straightening a stay blank; a revolu ble drum provided with a series'of rows-of movably supported formingblocks or dies-for-receiving said stay blanks andshaping the same after saidstay blanks have been severed into their proper lengths means for severing the stay blanks; means for actuating the said forming blocks or diesfor shapingthe stay blanks into a suitable form; means for discharging the formed stays from the said drum during its rotation, and means for returning the stay forming blocks I or dies to their normal positions on the drum after the discharge of the formed stays therefrom.

For a further and fulldescription of the invention herein and the merits thereof, and also to acquire a knowledge of the details of construction of thelmeans for effecting the result, reference ishad tothe following description and drawingshereto attached.

l/Vhil-ethe essential and characteristic features .of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figured is a generaliplan viewin outline of one form of wire fence machine with my improvements attached thereto, parts of the frame and support being shown as broken awayyFigQZis afrontelevation of the devices seen in planin-Fig. 1 ,Fig. 3 is an end viewlooking at the right hand side of Fig. 2; Fig. 4 -is-an enlargedlongitudinal cross section through the stay forming drum and showing a portion of a twister support; Fig. 5 is a transverse cross section through the stay forming drum and parts cooperating therewith and also -lshowing a cross section ofa portion of the twister support and twisters of parts connected with the lower faces of the formingblocks or dies and their positions are similar to the positions of the parts shown in Figs-'5, 8 and lOrespectively, with the ex- ,ceptionthat Fig. '14 shows a bottom plan view 'ofsuch parts as they are being returned to theirnormal positions; Figs. 15 and 16 are sectional views in elevation taken longitudinallythrough 1-4:, for the purpose of showing in detail the construction of certain plates-and'barsto which are attached rollers foroperating the forming blocks or dies; Fig. 17 is an end view ofthe stay forming drum showing the position of the cam and rollers-which-ride over the same, adapted to return the stay forming blocksor dies to their normalpOsitionsjFig. I8 is an enlarged longitudinal cross section V through certain clamping parts which are employed for gripping the stay blanks, preparatory to the stay blanks being bent into suitable form by the stay formers or dies; Fig. 19 is a plan view of one of the stay forming blocks or dies; Fig. 20 is a vertical cross section on the line x.r of Fig. 19; Fig. 21 is a longitudinal section on the line 'yy of Fig. 19 Figs. 22 and 23 show enlarged front and edge views of a twister for twisting the intermediate portions of a stay to the strand or stringer wires; Figs. 24 and 25 show a face and sectional view of a twister adapted to coil or wrap the ends of a stay about the selvage or margin wires; Fig. 26 shows a section of one form of fence adapted to be made on my machine.

On Jan. 9, 1905, William Grimm and myself filed an application for patent for improvements in wire fabric machines, which was given Serial No. 240,37 5. This machine consisted of a revoluble drum adapted to move in a continuous orbit, having a series of rows of twisters revolubly mounted thereon and adapted to receive a series of previously formed stays which were automatically delivered to the rows of twisters as they moved into position. The revoluble twister drum in the present application is somewhat similar to that described in the application above referred to with certain exceptions which will be hereinafter noted, but attention has been called to this application as it is thought unnecessary to show and describe a complete twister drum, with the twisters thereon, and the mechanism which is employed for actuating the said twisters during the movement of the drum. Except, that in the present application the ends of the stays are adapted to be coiled about the selvage or margin wires instead of being inter-twisted therewith.

One form of fence has been shown in the drawings (Fig. 26) and yet it is to be understood that with slight modifications the style of fence may be changed. That is to say, whilein the present application I prefer to show that the fabric is made with the ends of the stays coiled or wrapped about the margin or selvage wires, yet, it could be arranged so that the ends of the stays would be intertwisted or interlocked with the margin or selvage wires, substantially in the same manner as they are shown in the application for improvements in wire fence machines above referred to.

Attention is here called to the application for wire fence filed by William Grimm on June 14, 1905, bearing Serial No. 265,283, which shows several different forms offabric which may be made on this machine, however, Fig. 3 in such a plication for improvements in wire fence, i lustrates the preferred form. Attention is further called to the application for patent filed by William Grimm and myself on Sept. 13, 1905, bearing Serial No. 278,213, for improvements in wire stay bending machines, wherein stay forming blocks or dies are employed, which are in some respects similar to the stay forming blocks or dies shown and described in this application.

in the present application the twister drum is adapted to be provided with a series of longitudinal and circumferential rows of revolubly mounted twisters, the spacing of the twisters being at graduated distances apart necessitating the stay forming blocks or dies being correspondingly arranged; however, it is to be understood that they may be placed at uniform distances apart if it is so desired. By spacing the twisters and forming blocks at graduated distances apart it insures the manufacture of a wire fence fabric where the longitudinal stringer or strand wires are at graduated distances, producing afabric where the meshes at the bottom of the fabric are very close together. The longitudinal, stringer or strand wires, and the selvage or margin wires may be fed to the twister drum from a series of spools, reels or coils of wires, in any suitable manner, the twister drum serving as a positive feed for drawing the said wires from the reels, spools or coils and together with the stays delivering the same in the form of a finished fabric to a suitable wrapper or take-up that rolls up the finished fabric. During the passage of the longitudinal wires of the fabric over the twister drum, stays are adapted. to be deposited in the twisters and the twisters are actuated during a partial revolution of the drum for intertwisting or interlocking the stays with the longitudinal wires where they intersect, all of which will become apparent and be better understood from the following description.

Like numerals of reference indicate corresponding parts throughout the figures.

In the drawings a support which will be hereinafter referred to as the twister drum, comprises a shaft 1 which is adapted to be journaled at its opposite ends in boxings formed upon or attached to uprights or standards 2, forming a part of the main frame of my machine. 1n the drawings there is only one of the standards or uprights 2 shown, as the machine is of considerable length and only one end of the machine is shown. The standards 2 at their lower front ends are adapted to be connected by the braces or sills 3 and they may be otherwise braced if it is so desired. The twister drum further consists, of the disks 1- which are secured to and suitably spaced apart on the shaft 1. Interposed and extending between the said disks are a series of pairs of parallel frame supports 5, see Fig. 5, which are suitably spaced apart. At intervals throughout the length of these supports are secured .plates 6 in which are revolubly mounted twisters 7, the same havingslotted portions 8 for the reception of certain wires and provided with toothed peripheries whereby each row of twisters may be actuated simultaneously through the agency of rack bars 9, all of which is best seen in Fig. 5. The plates 6 are slotted at 10 to correspond to the slots 8 in thetwisters 7, and the supports 5 are likewise slotted at 11 which correspond with the slotsin the plates 6 and; the twisters 8. The rack bars are adapted to have longitudinal movement between the parallel supports5 and are reci rocally mounted on rests or bars 12 to whicl i the lower edges of the supports 5 are connected. The en ports for therack bars, therack bars, the p ates which serve as bearings for the twisters, and the twisters, are all shown in a general way, and while the twister drum has been illustrated in outline and gen erally referred to, no means have been shown for operating the rack bars as this is not thought to be material in this case as it is intended that the twisters may be actuated either by rack bars, or some other longitudinally movable means or gearing, if it is so desired.

The longitudinal wires, such as stringer, strand, margin or selvage wires, are generally referred to as 13, see Fig. 5, and are fed to the twister drum in the manner heretofore indicated, by being assed partially around the drum and through the slots in the plates 6 and also the slots in the twisters 7. It is intended that when the staysare dropped Y onto the twister drum, portions of the stays will be seated in the slots of the plates 6 and also the slotsofthe twisters 7 and when the said twisters are actuated they will berotated a sufhcient number of times to intertwist or interlock that portion of the stays seated 111 theplate 6 and the twisters 7, with the stringer wires 13, substantially as is shown in Fig. 26 which illustrates a section of a fabric. It is intended that the tn ister drum shall be revolved in a continuous orbit, which will facilitate in the continuous manufacture of woven fabric, the stays which will cross the stringer wires being deposited onto the twister drum and into the twisters during the continuous rotation of said twister drum.

Any suitable means may be employed for transmitting motion from a suitable source of power to the shaft 1; but in Fig. 3 on the far end of the shaft 1, I have shown an en-- larged gear wheel 14 which intermeshes with the inion 15 carried on a. driving shaft 16 whid h may be connected by a belt or some other suitable means with a suitable source of power, the shaft 15 being journ'aled inan extension of the'framefrom the uprights or standards 2.

In Fig. 26 the section of the fence fabric there shown, shows that the ortions of the stays which intersect with al of the intermediate stringer wires are preferably intermargin wires.

locked by a right and left intertwist of the said stays with the stringer wires, this is accomplished through the provision of that form of slotted twister which is shown in Fig. 5 and best seen in detail in Figs. 22 and 23. Fig. 26 also shows that the ends of the stays are coiled or wrapped about the selvage or This I accomplish by placing at the end of each series of twisters a slotted twister which is indicated as 17, best seen in Figs. 24 and 25. The twisters 17 differ from the twisters 7 in that the twisters 7 have clamping parts 18 which serve to clamp the wires which are seated in the said twisters, while the outside or selvage twisters 17 are minus the parts 18 employed in the twisters 7; the ends of the stays are dropped alongside of and adjacent to one face of the twisters 17, on which said face is provided a coiling pin 19, adapted through the rotation of the saidselvage twisters to engage with the free ends of the stays and coil or wrap them about the selvage or margin wires extending through the twister 17. V

I will now describe the forming means cooperating with the twister drum, for receiving successively stay blanks and bending the said stay blanks into suitable form and depositing the formed stays into each row of twisters as they are successively brought into position by the continuous rotation of the twister drum; and in connection with said forming mechanism, I will describe the means for feeding the said stay blanks thereto, cutting such stay blanks into proper length, and the manner of depositing the same on to the forming mechanism and for holding one end of the stay blanks preparaism for bending the stay blanks; the descrip tion to also include means partially overlying the twister drum which discharges or insures the delivery of the formed stays into the rows of twisters as they come into proper alinement with said forming mechanism.

20 denotes a longitudinally supported shaft, preferably located in vertical alinement and parallel with the axis of the twister drum shaft 1. The shaft 20 is journaled at its op osite ends in brackets 21 which are suitab y secured to a frame part 22 supported at its opposite ends on the standards or uprights 2. Said shaft 20 receives its power from the shaft 1 through and by means of the gear 23 on the shaft 1 which intermeshes with the gear 24 on the shaft 20. On the shaft 20 are revolubly carried a pair of spaced disks or drum heads 24 to which are secured the opposite ends of a series of longitudinal bars 26 which are preferably spaced equidistant from each other around the heads or disks 24, substantially as seen in Fig. 5 and interposed between the said bars and having their opposite ends secured to the heads or disks 2 1* are a series of filler plates tor to the o eration of the formin mechan- 27. The heads or disks 24, the bars 26 and plates 27 form the foundation of the former drum on which are pivotally mounted the forming blocks or dies 28 which are arranged in a series of longitudinal and circumferential rows on the drum composed of the heads 24 bars 26 and plates 27. Such forming blocks or dies are arranged in a series of rows and are pivotally connected with the bars 26, being preferably spaced on said bars at graduated distances for the purpose of forming stays to be interweaved with a series of runner wires so that the meshes of the fabric when completed will be at graduated distanees from the bottom to the top of said fabric. Each forming block or die 28 has a central depending stud 29 which passes through the bars 26; and on said depending studs 29, just below the bars 26, are secured the cam blocks 30; and for holding such cam blocks and the dies in working position on the bars 26, the lower ends of the studs 29 are threaded as at 31 and are adapted to be engaged by the nuts 32. The body portions of the forming blocks or dies 28 are preferably made rectangular in form and with a longitudinal groove 33 extending down into and through the same. I have provided the forming blocks or dies with the body portions thereof upon the opposite sides of the slots or grooves 33 higher on one side than on the other, for purposes which will become apparent and at the opposite ends of the said slots or grooves and upon the opposite sides and at each end thereof I have provided the

rollers

34 and 35. The forming blocks or dies 28 are so positioned on the bars 26 to which they are connected that the stay blanks when they are dropped on the drum su porting the said forming blocks or dies wil fall first upon the low side of the said blocks or dies and in the movement of the forming drum Will, by suitable means be forced against the higher portions of the blocks and caused to drop into the slots 33 of said blocks or dies, preparatory to the operation of the blocks for bending right angle portions into the stay blanks. In their normal position the forming blocks or dies 28 have their slots or grooves 33 extending longitudinally with the axis of the drum on which they are supported and they remain in this position during the rotation of the said drum until after a row of formers have received a stay blank, when by the rotation of the drum, the said blocks or dies are caused successively to make suitable turns on the bars 26; alternate blocks swinging in the same direction, thus forming angular portions in the stay blanks; and after the proper bending of the stay blanks the drum rotates into a position where a row of forming blocks or dies overlies and is co-incident with a row of twisters on the twister drum when the formed stays are caused to be discharged into the said twisters, after which and during the remainder of the rotation of the former drum, the blocks or dies are returned to their normal positions with the slots or grooves extendinglongitudinally with the axis of the drum. The stays which are used for making the said fabric are preferably provided. with right angle portions; consisting respectively of alternate vertical and horizontal portions, the horizontal portions to be intertwisted with the running wires of the fabric and the vertical portions to extend between adjacent longitudinal wires and the opposite ends of said stays to be coiled or wrapped about the margin or selvage wires. By vertical and horizontal portions are meant the portions of the stays, which assume these positions when the fabric has been placed in a vertical position. To form such angular portions in the stays, it is only necessary to oscillate the forming blocks 28 one-quarter way around as shown in Fig. 10.

In Fig. 4 it will be noted that the forming blocks are made to coincide with each of the intermediate twisters on the twister drum and by reason of the marginal twisters being adapted to coil the opposite ends of the stays about the margin wires, there is no necessity of providing a forming block or die for the marginal twisters as the stay blanks are left straight, substantially as appears in Fig. 10 of the drawings.

In the rotation of the former drum, a means is provided, by which each forming block beginning with that on the left hand, is operated so that adjacent blocks move in 0 Y posite directions, each successive block a most making its complete turn, before the next in line starts to operate. This operation is carried out successively with each row or set of blocks during the continuous rotation of the former drum.

The means for actuating the forming blocks or dies to partially rotate them on their pivots consists of a series of wedging

bars

36 and 37. The wedging bars 37 being similar, are given a corresponding numeral and the wedging bar 36 serving the additional function of operating suitable clamping parts is given a distinguishing numeral from the other wedging bars, so as to avoid confusion, and have preferably concave faces to adapt them to ride over the surface of the former drum as the same is rotated for the purpose of engaging the forming blocks or dies during the revolution of the drum. The wedging bars are further disposed on a stationary sup )ort in such a way as to turnsuccessively the blocks in each row beginning with the left hand block, each making almost its complete turn before the next to its right is engaged, adjacent blocks moving in opposite directions. To the support 22 is suitably secured a plate or bar 38 having a concave face 39, see Fig. 5, to

which the wedgingi'bars 36 andigf are adept ed to be secured.

As will be noted in=the drawings, particu larly Figs. 6,7 and 8, the w'edgingdsarsfid and 37 are rovidecb with. wedge or cam faces adapter to engage withx thef-forming; blocks or (llGS 28, substant ally as seeniln:

Fig. 8, for. swingmgjthesaid blocks:v onequarter-way around on their pivots for shape ing a stay blank into the formishowniniFig; 10. To insure the deposit of the stay blanks,- after theyv are straightenedandicut; into a row of-formingblocks or dies-28, Lprovide a series of guide fingers 40,.some of which may be securedtoand project up fromthe wedging bars 36 and '37, and others which,

low sides of'theforming blocks or dies 28"asthey move into position=during therotation of the formingdrum; They further assist in its deposition by forcingit into the former slots during the rotation of said former drum.

The guide lingers which have been referred to as being attached toithe wedging bars 36 and 37 may be formed integral with the said bars, it it is so desired, and the said fingers extend downwardly and forwardly from the lower ends of the wedging bars 36- and 37 and the plate or bar 38, as best seen in Fig. 5. The lower ends of said guide lingers terminate at a point just above the twister drum where it is adapted todischarge the formed stay blanks from the forming blocks or dies into the twisters '7 and 1.7. By the time that the forming blocks or dies 28have reached the lower l'orwardends of the guide fingers 40, the said blocksor dies have been swungsuiliciontly on their pivots, so as to shape the stay blanks into the form shown in Fig. 10, and the said blocks or dies remain in this positionuntil alter the discharge of the formed stays therefrom, when, by means which will be described, the blocks are returned to the position shown inFig. 6. To prevent accidental displacement or discharge ol' the stay blanks from the forming-blocks or dies, it is provided that the wedging-bars and guiding :iingors willride above the'stay blanks in the rotation of the forming drum,

. J. as be Lll\.' or dies are deep enough so that the stay blanks will ride beneath the said wedgingj the wedging bars engage the formingblocks or dies to oscillate them ontheir bars pivots, tl s is very clearly seen in 9 and removal of the formed stay blanks lromthe slots or grooves in the forming blocks overliefa row of :twisters in the movement of the twistervdrum, consists of a seriesof disehargeafingrsAZ.whichiare secured at a suitablepoint. i'ni their: length to brackets 43 attachedito a frame 44. supported by uprights 45 -fron1athe cross-brace 3, as best seen in Figs: 2. and 5.. The fingers42 project upwardly and rearwardly andiarc concave, orshapedtocontorm to :the surface of the twister: drum,.as will bese'en in Fig. 5 and their upperi rean ends are curved 1 upwardly. or opposite to the body. portions thereof so as-to havea convex lower face as shown. The said fingers 42. are interposed and ride betweeln the: twisters and bearing plates supporting the same on the twist er drum and the upper "ends: thereof are interposed *and ride b'etweenithe forming blocks or dies on the formingidrum, all of which will be seen from an examinationTobFigs. 2'and 5. As the formingblocks or dies leave. thelower forward ends of the guidingiingers 40, the stay. blanks are. caused to engage with the upper rear ends of the dischargefingers 42. andthey. are 'forc'ed down on. to the twister drumiand' into thetwis-ters, as will be seen from an'examination of Fig. 5 ol' the drawings; .the forming, blocks and twisters as above described, coincide as the forming blocks leave thelower. ends of the guiding and in the twisters until they are locked there by the revolvingtwisters. It is preferable toset the twisters oi'each row in operation at agiven point in the movement of the-drum, .and il'it is desired the mechanism for actuatingthe said twister-s may be so arranged that one or; more rows of twisters may be actuated simultaneously, although it is not intended to place any limitation on the number oirows whichimay be actuated at a time.

Extending. longitudinally through the forming drum and. reciprocally supported therein are a series of pairs of bars 46, one pair of bars for each row of iormingblocks or dies and disposed below the same in the said drum, see Fig. 4.. These bars at one end are reciprocally mounted in one of the heads or disks 24* and the opposite ends of the said. bars are suitably secured to an elongated head 47 which are reciprocally mounted. and extend through the opposite head or disk- 24, best: seen in Fig. 4 of the drawings.-. It is intended that the outer face of: the bars 46 shall'be on; a plane with the inner faces of the cam blocks referred to as carried by the studs 29 of the forming blocks or dies 28, and said cam blocks when the forming blocks or dies are swung on their pivots are adapted to swing across the outer faces of the bars 46. That is to say, the cam blocks .of the alternate forming blocks or dies are adapted to swing across the opposite bars 46 .of each pair of bars as best seen in Figs. 13 and 14 of the drawings. With this arrangement I have provided a series of alternately spaced rollers 48 which are revolubly attached to the outer face of the bars 46; those .on the extreme left of each set are adapted to be engaged by the left hand earn blocks 30 when they are swung in the operation of the first forming block or die 28 of each row, while all of them are employed in returning the forming blocks to their normal position by engaging said cam blocks. In Fig. 11 of'the drawings, a bottom plan view of the bars 46 is shown and 7 their position together with the cam blocks therewith, is a cam 51.

30 corresponding to the position of the forming blocks or dies when they receive a stay blank preparatory to shaping the same. As the wedging bars 36 engage the first forming block or die to the left of each row of said blocks or dies and the same is oscillated on its pivot, the cam block attached thereto will engage its respective roller 48 and reciprocate the pair of bars 46 lying beneath that row of forming blocks or dies, in one direction or to the left when looking at Figs. 4 and 12. Each pair of bars 46 when projected in the manner just indicated, through the operation of the first forming block or die of each row thereof, will remain in such position until after the discharge of the formed stay into a corresponding row of twisters on the twister drum. The function of the bars 46 and rollers 48 is to return the forming blocks or dies to their normal positions after the discharge of a stay therefrom and when they are projected in one direction through the operation of the first block or die of each series they are simply placed in position to adapt the rollers 48 attached thereto to engage with the cam blocks 30 for returning the forming blocks or dies to their normal ositions.

On one en of the shaft 20, preferably the right hand end thereof looking at the machine from the front, is supported a stationary head 50, which is secured to the bearing of the said shaft; and attached to the pe riphery of the head 50 or formed integral To the outer ends and inner faces of the heads 47 to which each pair of bars 46 are connected, are revolubly connected rollers 52, the inner ends of which ride around the periphery of the head 50 and the said rollers are adapted to ride on the cam 51. When the bars 46 are projected to the left, the rollers 52 are brought adjaesoeee cent to that portion of the cam 51 which lies in juxtaposition to the head or disk 24 for a considerable portion of its length and at a suitable point in the revolution of the forming blocks between the time the stays are expelled and again received, the rollers 52 begin to travel adjacent to a sinuous or irregular portion of the cam 51, see Fig. 2, which is such as to move the head 47 and l the bars 46 to the right, or in a direction opposite to that previously described, when the same were moved through the actuation of the first forming block or die of each series. The movement of the bars 46 through the action of the rollers 52 as they ride over the sinuous or irregular portion of the cam 51 will cause the rollers 48 to engage and oscillate the cam blocks 30 in the manner shown in Fig. 14, which will return the said forming blocks or dies to their normal or initial positions.

In depositing a stay blank into a row of forming blocks or dies on the forming drum, the longer portions of the said stay blanks are preferably at the right hand end of the 1nachine when looking at the front, so that when the said stay blanks are formed into the right angle portions the slack of the said stay blanks will be drawn from the longer por tion of the said stays. And to prevent the left hand end of the stay blanks from being projected toward the right as they are formed into their right angle portions, I arrange to clamp or grip the left hand end of each of said stay blanks during the rotation of the forming drum, and at such a time before or just at the beginning of the operation of the first forming block or die as \Vlll hold the said stay during the oscillation of said first forming block or die. The clamping or gripping means ust referred to, consists of a series of base plates 53, one for each row of forming blocks or dies 28 and secured to said plates 53 are bars 54 provided with elongated slots 55. To one end of the base plates are pivotally connected crank arms 56, to which at 57 are pivotally connected longer arms or reaches 58; and at the junction of the said arms and reaches are carried rollers 56-".

The arms 58 have a pivotal connection at 11 their opposite ends with the gripping blocks 59 which are slidably mounted on the bars 54 and retained in working position thereon by pins or studs which operate in the slots of the said bars 54, as best seen in cross section in Fig. 18. Cooperating with the grip ping blocks 59 are companion blocks 60 which are secured to the bars 54, as shown in the figures. When the stay blank is dropped into a row of forming blocks or dies 28, as seen in Fig. 6 and just prior to the wedging bar 36 engaging with the first forming block or die 28 a cam face 61 thereof will engage the rollers supported by

arms

57 and 58, as above stated, and will move the arms in the manner seen in Fig. 7, sliding the gripping block 59 along on the bar 54 until the stay has been forced against said gripping block 60 for firmly holding the said stay blank at this end, until, the first forming block or die 28 has been oscillated or turned one-quarter way around as shown in Figs. 8 and 9, when that portion of the wedging bar 36 will have passed beyond the pivotal connection on the reach 58 with the crank arm 56 when the coil spring 62, see Fig. 18, will operate to return t e crank arm 56, the reach 58 and .the gripping block 59 to their normal or initial position as shown in Fig. 9.

As the forming drum is revolved, there is provided means for holding the right hand end of the stay blank as the last block of the series of forming blocks or dies of each row is operated, so'that the free end of the stay blank will extend longitudinally with the opposite end thereof, both of'which ends serve as the portions of the stay which are adapted to be coiled or wrapped around the selvage wires of the fabric. Attached to the surface of the forming drum and spaced at suitable intervals around the same I have provided the engaging blocks 63 with which the right hand end of a stay blank will engage as the last block of a series is being rotated, substantially in the manner seen in Fig. 9 and after the last forming block has completed its movement the right hand end of the stay lp lank will have assumed a position shown in ig. 10. r

The wire which is fed across themachine and from which the stay blanks may be severed, may be fed to the said machine from a coil of wire or from spools or reels on which the said wire is wrap ed. It it preferable to feed the wires from w ich the stay blanks are severed, through a suitable straightening and guiding device and while I have shown and will refer to one form of straightening and guiding device, it is to be understood however, that any suitable form serving the purpose, may be substituted. And while I have shown that aseries of similar cutting members are adapted to and movable with the forming drum, it is understoodthat both of the cutting members severing a stayblank, from a length of wire, may form a part of the straightening and guiding means. In fact, there are several well known straightening and guiding devices which might serve the purpose equally as well as the one herein adopted and I do not wish to be confined in the present device to such straightening and guiding mechanism.

The straightening and guiding means consists of a series of vertically and horizontally rotatable members 64 and 65, see Figs. 1 and 2, which are journal'ed in a suitable support 66. The feeding rollers for advancing the wire from which the stay blanks are severed are indicated as 67 and 68 which are jour naled on short spindles 69 which have a bearing in suitable boxings attached or secured to the support 66 and the manner of transmitting motion to said feeding rollers, consists of a short driving shaft or spindle 70 on one end of which is a sprocket pinion 71 driven by a sprocket chain 72 from any suitable source of power; and on the opposite end of the said short shaft or spindle 70 is a bevel gear 73 which intermeshes with the bevel gear 7 4 carried on the shaft or spindle on which is car ried the lower feeding roller 68, and on such shaft is also carried a spur pinion which meshes with the spur pinion on the shaft or spindle on which is carried the feeding roller 67. These parts are all best seen in Figs. 1 and The support 66 in advance of the feeding rollers 67 and 68 is provided with a bearing block 75 through which the stay wire is adapted to be fed and the front face of the said block is adapted to serve as one of the cutting members for severing the stay wire into proper lengths. The stay wire passes from the block 75 through a guide consisting of the hinged bars 76 and 77 the latter of which is provided with a wire groove, 78, see Fig. 5. The

parts

76 and 77 are adapted to be hinged together throughout their length at short intervals as at 79 and in such a manner that the bar 77, may, at predetermined. intervals, swing upwardly and away from the bar 76 to allow a stay wire blank, after it has been severed from a length of wire, to be dropped on the curved forward ends of the guiding finger 40 and from which these-wires find their way into the grooves or slots of the succeeding rows of the forming blocks or dies. The

guidingbars

76 and 77 may be supported in any suitable manner but I have shown the same supported by the brackets 79 one of which has its lower end connected with the frame 44. and the other is supported from one of the standards or uprights 2, see Figs. 1 and 2.

On the forming drum is suitably supported a series of cutting members 80, one each lo-,

cated at the left hand end of each row of forming blocks or dies, as shown, and said cutting members are adapted to co-act with the cutting face of the block 75 for severing a stay blank from the coil of wire as each row of forming blocks or dies move into position to receive the same from the guiding bars 76 and 77. The cutting members are so positioned on the forming drum with respect to the forming blocks or dies and the means for operating the same, that a wire stay blank is severed in suflicient time to enable their discharge, by means to be described, from the guiding bars 76 and 77, so that they will find their way into the slots or grooves of a row of forming blocks or dies when they have moved into position, throu h the rotation of the drum, for receiving tie same. In this connection it might be said,

that the cutting means for severing a stay blank from a length of wire may be so positioned that more or less 01 an end of a stay may be left at the left hand end thereof, so that when the end of the stay is coiled or Wrapped around a margin or selvage wire, that it may be completely wrapped through the rotation of the selvage twisters around the selvage or margin wires or a short length left to serve as a barb, and this is also true with respect to the length of the stay blank which may be correspondingly lengthened or shortened'so as to form a barb or not, at the opposite end of the said stay, if it is so desired. The bar 77 is raised through the action of the forming drum and may be re turned by any suitable means; in this instance the return of the bar has been accomplished through a yielding means. At or near the opposite ends of the bar 77 are attached or secured arms 81 which extend downwardly and forwardly and beneath the bar 76, as best seen in Fig. 5, and with the ends of the extensions of said arms are adapted to engage a'series of blocks 82 arranged in a circumferential row on the forming drum and at the opposite ends of each row of forming blocks or dies, see Fig. 1. These blocks, during the rotation of the forming drum, successively engage with the arms 81 and swin the bars 77 upwardly, which said movement will release a stay blank from said bars, and allow the same to fall on the forming drum. As the blocks 82 disengage themselves from the arms 81,- the said bar 77 might possibly, through gravity, drop back to its normal or initial position, but to obviate the danger of the said bar not returning to its original or initial position, I provide the springs 83 which engage at one end with extensions of the brackets 7 9 and at their opposite ends with the bar 77, as best seen in Fi 5.
