SPECIFICATION forming part Of Letters Patent N 0. 744,442, dated November 17, 1903.
Application filed January 6, 1902. Serial No. 88.592. (No model.)
0 all 107mm 1715 may concern.-
lle it known that I, ERNEs'r VAHLE, a citizen of the United States, and a resident of \Vcst IIoboken, in the county of Hudson and State of New Jersey, have invented a new and Improved Loo'm, of which the following is a full, clear, and exact description.
The object of the invention is to provide a new and improved loom for weaving all kinds of textile fabrics and arranged to carry the doubled-up weft-thread through the open shed by a spoolless shuttle, to produce a fabric having double weft-threads in each pick, the arrangement permittingthe production of plain goods as well as figured goods with the aid of a jacquard.
The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.
A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all of the views.
Figure 1 is a longitudinal sectional side elevation of the improvement, showing the lay in a beating-in position and the picker mechanism omitted. Fig. 2 is a transverse section of the same on the line 2 2 of Fig. 1. Fig. 3 is a sectional plan view of the same on the line 3 il of Fig. 1. Fig. 4. is a like view of the same, showing the parts in a different position. Fig. 5 is an enlarged sectional side elevation of the lay and parts carried thereon. Fig. 5 is a similar view of the same, on a reduced scale, with parts in a dilferent position. Fig. 13 is an enlarged sectional plan view of the shuttle, the shuttle-race, and the mechanism controlled by the shuttle for operating the loop-needles and the locking device for the weft-thread guide. Fig. 7 is a like view of the shuttle, showing parts thereof in a different position. Fig. 8 is an enlarged rear sectional elevation of the weft-thread spool of the holding and releasing device for the weftthread and adjacent parts. Fig. 9 is a side elevation of the actuating device for the weftthread gu ide w h on weaving plain goods. Fig. 10 is an enlarged front elevation of one of the hooks for guiding the weft-thread to the open shed. Fig. '1 l is a plan view of the same.
Fig. 12 is an enlarged perspective view of the fabric, showing the open shed, the weft-thread in position therein and looped onto the needle. Fig. 13 is a longitudinal sectional elevation of the weave.
In the fabric A to be wovenby the loom warpthreads A' are bound in by doubled-up weftthreadsA and A alternately passed from opposite sides of the loom through the open shedthat is, in the first pick, say the doubled-up weft-thread A is passed from the right to the left through the open shed from a spoolA, located on the right-hand side of the machine, and then during the next pick the donl aled-up weft-thread A is passed from the left to the right through the open shed from a spool A, located on the left-hand side of the machine, (see Fig. 2,) the ends of the weft-threads being held in the selvage of the fabric, as indicated in Fig. 12. In order to weave the fabric, it is at least necessary that two weft threads A and A from separate spools A and A be employed; but the number of spools and weftthreads for each side of the loom may be increased, especially when it is desired to weave figured goods. As shown in Fig. 2, two spools A and two spools A are provided for each side, and each of these spools carriesa differently-colored weft-thread to'allow of weaving figured goods according to a predetermined pattern, and in this case a jacquard is required to bring the desired weft-threads into action. In case plain goods are woven the weftthreads A and A are alike in color, and in this case the jacquard can be dispensed with; but instead of the jacquard the device shown in Fig. 9 is employed to bring the weftthreads A A for successive picks alternately into active positions. The loom for weaving this fabric is arranged as follows:
On the frame B are arranged the usual beams B and B for the fabric A and warpthreads A", as plainly indicated in Fig. l, and in the said frame B is journaled the main or crank shaft U, having crank -ar1ns U, connected by pitman with the lay l), fulcrumed at l)" in the frame B and provided with the usual reed I) for beating in successively the doubled-up weftthreads A A The warp -thrcads A are held in the usual heddles E, and the doubledu p warp-threads A are carried alternately through the open shed by a spoolless shuttle F, mounted to travel from one shuttle-race I) to the other shuttle-race l and back again, the shuttle being propelled from one shuttle-race to the other by a suitable picker mechanism. (Not shown.) The shuttle-races l) and I) are integral parts of the lay I), and consequently move with the same as the latter swings forward and backward when the loom is in action. The shuttle F is pointed at its ends in the usual manner and is provided in its trout side with a retainingdevice for ei'igagingthe loops A of the doubled-up weft -threads A A to alternately carry the same through the open shed. This retaining device consists, essentially, of a lug or button F, mounted to slide transversely in the sh little-body, thelug when in an outermost position beingadapted to engage the loop A" and when moved into an inward position casts oii' the loop A shortly after the shuttle has passed through the open shed and entered the corresponding shuttlerace I)" or IV. In order to move this lug F transversely in the shuttle F, I provide the following device, special reference being had to Figs. 6 and T. The innerend of thelug F is engaged by the inner ends of levers and F extending lengthwise in the shuttle F and in opposite directions from the lug F, the said levers being provided near theirtulerum ends with pioieetions F F, oi which the projection F is adapted to engage a spring I), arranged in the front of the shuttle-race l), and the lug F is adapted to engage a similar spring I), but located in the other shuttle race D". Now when the shuttle F passes into the shuttle-race 1). as indicated in Fig. It, then the projection F engages the spring I)", so that the lever F is swung inward, and in doing so moves the lug F likewise .inward to cast Oil the loop A oil the weft-thread A. In a like manner when the shuttle F moves into the shuttleraee l) then the projection engages the spring I) in the said shuttle -race 'and causes a like inward movement: of the lug F to cast olt' the loop A of the weftthrcad A. \Vhen the projections F and F" are not in engagement with theircorresponding spring I), then the lug F is held in an outermost position by a spring F pressing against the inner end of the lug F", as will be readily uin'lerstoml by reference to Figs. It and T.
In order to prevent the loop A" from aecidentally sliding oil the lug F, I provide the retaining-arms G and G, l'ulcruined in a recess in the front end of the lug F, (see Figs. 5, (3, and 7,) and the said arms are normally pressed into an outermost retaining position by a spring G, so as to hold the loop A on the lug F. The inner ends G of the arms G G are adapted to be pressed apart by the poin ted end of a pin G, rigidly secured in the casing F in which the lug F' slides, so that when the lug moves into a rear-most position, as previously explained and shown in Fig. U, then the inner ends G of the arms G (r' move in contact with the pin G", and are thereby spread apart to draw the free ends of the arms G G" into an innermost position-that is, in the recess in the lug F' to allow the loop A to readily slide oil at the time the lug F' movesrearward. As soon as the lugnuwcs outward and engages the next loop A then the arms G G move again into an active position, as shown in Fig. 7, to hold the loop A" against accidental displacement from the lug F'.
In order to bring the active wettthread A or A in and out of position at each end of the open shed for the lug F to take hold of the loop A, I provide gn ide-hooks ll ll and mechanism fori'ictuatingthe same, each guide-hook ll ll operating in conjunction with corresponding welt-thread holding and releasing device I, located immediately above the corresponding spool A A and above which device I is arranged a spring- .I, from which passes the corresponding wettthread A or A to an eye I) or D held on the top rail of the lay I). The mechanisms for bearing the guide -hooks are simply duplicates one of the other, and the several holding and releasing devices I are alike in construction, also the eyes J and l)" and I), so that it sul ices to describe one of each duplicate device in detail.
inch of the guide-hooks II II is provided ith a shank ll", from the upper end of which extends longitudiintlly the horizontal arm 1 l, terminating in a hook proper, II, as plainly indicated in Figs. 5, lo, and 11, the hook ll being adapted to engage the corresponding we ft-thread A or A below the eye I)" at the time the lay D is in a rearmost position. The shank ll of the hook is fastened by a setscrew ii in the upper end of a rod K, mounted to slide vertically in suitable bearings K and K formed on a bracket k boltedorotherwiso fastened to the underside oi the lay I), as plainly indicated in Fig. 5. A spring K is coiled on the rod h and rests with its lower end on the bearing K and presses with the upper end against a collar h", normally resting against the under side of the bearing If. The rod h, and with it the guide-hook II or ll, is drawn dowmvard into an active position by the action of the jacquard Ii,-and in order to do this thelower end oi. each rod K is connected with one end oi a rope N, extending over pulleys N", N N", and N, and connected at its other end with the lower end of a hook l/ of the jacquard L, the said book being adapted to be lifted periodically bythe lever I and to draw the rod h downward against the tension of its spring K and until the spring-catch snaps oil? over the top of the collar K so as to lock the rod K temporarily against a return or upward movement. On each hook L of the jacquz'ird is arranged a wedge I), (see Fig. 2,) adapted to engage a projection If on the frame of the jacquard, so that when the hook L" is elevated into an uppermost posi tion by the lever L then the said wedge L presses the hook L to one side to disengage the upper end of the hook from the lever L As soon as this takes place the hook L drops back to a lowermost position and a spring N on each rope N draws the latter back, it being understood that the spring was exerting a pull on the rope l\" by the lifting of the hook L. The catch 0 holds the rod K in a lowermost position during the time the lay l) is in a rearmost position, so that the hook ll holds the corresponding weft-thread A A in the path of the shuttle to allow the lug l thereof to engage the corresponding loop A to allow of drawing the doubled-up weftthread through the open shed from one side to the other. (See Fig. 5%) The catch 0 is released by the shuttle entering the opposite shuttle-race, so that the spring K forces the rod K back to a normal uppermost position, thereby releasing the corresponding weftthread A or A for the time being.
In order to withdraw the catch 0 from the collar K I provide the following device: The catch 0 is mounted to slide in the bracket K (see Fig. and is pressed on by a spring 0" to normally hold the catch in an outermost position for ei'lgagement with the collar K when the rod K is moved downward. On the inner end of the catch is arranged a head containing a spring pressed catch adapted to be engaged by one end of a lever 0 fulcrumcd on the bracket K and pressed on by a spring The lower end of the lever U is adapted to be engaged by an arm 0, seoured on a transversely-extending roek-shaf t journaled in suitable bearings on the lay I), so as to move with the same. ()n the shaft are secured two upwardly-extending arms 0 and (7)", engaging the rear faces of the levers l and l fulcrumcd at their outer ends l and P in the rear sides of the raceways D and I), the said levers extending in slots arranged in the raceways, so as to project with their forward faces into the raeeways for the shuttle 1* to swing the levers 1 andl outward at the time the shuttle passes into the corresponding raceway I) or D. As previously stated, the rod K is locked by the catch 0 in a lowermost position during the time the shuttle passes through the open shed, so that the hook ll properly guides the corresponding wel't-thread A or A to the open shed, and as soon as the shuttle enters the raceway I) or 1) then it brings the corresponding lever P or P outward, and thereby gives a swinging motion to the arm to rock the shaft which by the arm 0 imparts a swinging motion to the lever and as the latter engages the spring-catch t) it is evident that the catch is caused to slide rearward out of engagement with the collar K to re lease the rod K. As soon as this takes place the spring K immediately E'irces the red I( upward, so that the hook ll discngages the corresponding weft-thread 1V or A. The
weft-thread A or A is thus released previous to the lay beating in the weft-thread.
From the foregoing it will be seen that the shuttle when entering the raceways l) and 1) controls the releasing of the weft-threads by the hooks ll". The shuttle h also controls the needles Q and Q", employed for engaging the loop A" of the weft-threads A and A at the time the loops are cast off from the lug h" ofthe shuttle l-that is, at the time the shuttle passes into the corresponding raceway l) or I). The needles Q and Q" extend longitudinally adjacent to the edges of the weave, as plainlyindicated in Figs. 25 and 4. The needles (3 Q move bodily with the lay D and have a longitiuliual movement to bring the needles into a forward position for receiving the loop A as soon as the shuttle has left the open shed and passes into the corresponding raceway l) or I). As soon as the doubled-up weft-thread A or A just laid in the open shed is beaten in by the lay then the needle Q or Q moves rearwardly and out of the path of the shuttle, so that the latter can return to the other side of the loom during the next pick.
The mechanisms for i'q'ierating the needles are arranged as follows, special. reference being had to Figs. 3, l, and H: The needles Q and Q, are secured on the rods Q and Q, mounted to slide loi'lgitudinally in the easings R lt, attached by brackets R to the race *ays l) l), and each of the said rods Q is pressed on by a spring Q and normally holds the corresponding needle Q or Q in a forward position. On the rods Q and Q are secured or formed lugs Q and Q, extending through slits R" in the casings R 1%, and the said lugs are adapted to be engaged by spring-catches 5* held in the front ends of the levers b l'ulcrumed on the casings ll 1%, respectively, each lever S S being pressed on by a spring S to normally hold. the lever b or b" in such position that the spring-cz'ttch S engaging'the,
corresponding lug Q", is in a normal forward position. The ends of the levers S S are adapted to bear against stops S S held adjustably in the frame B and adapted to be secured therein by set-screws S" to allow of properly adjusting the stops S It will be seen that when the needle Q or Q is in a forward position and engages the loop A and the lay swings rearward then the lever S or lirmly moves in contact with the corresponding step b" 5", so as to impart a swing ing motion to the lever and cause the catch 8* to draw the lug Q or Q", and with it the rod Q or Q and needle Q or Q, in a rearward direction for the corresponding needle Q or Q to disengage the loop A. At the time this takes place the lay has reached almost an in nermost position, and when the lay moves into a final rearward position then the catch slides oil the corresponding lug or Q"; but at this time a catch (3 has moved in engagement with a collar Q? on the corre spending rod Q or Q so as to hold the latter in a rearmost position against the tension of the corresponding spring Q.
The catches (3 above referred to are springprcssed and mounted to slide in bearings attached to the casing R or R" and are provided with springcatehes Q, which move bodily therewith, of which the spring-catch Q" on the casing R is adapted to be engaged by a lever T, and a similar lever T is adapted to engage the spring-catch Q on the casing it to withdraw the spring-catches Q from the collars Q and allow the spring Q" to move the rods Q and Q outward for the needles Q and Q" to engage the next loop A. Now this releasing of the rods (2' and Q by the spring-catches (2* is controlled by the shuttle F entering the eorres imnding raceway D or I), and for this purpose the levers T and T are adapted to be engaged by levers T T, fulerumed on the raeeways l) I) and carrying buttons T and T resting on the levers l and I previously described. Eat-h ofthe levers T and T is provided with a notch T, and each lever T is pressed on by a spring T A pivoted arm T, pressed on by a spring T engages the corresponding lever T (or '1") for the purpose hereinafter described. The lever T (or T) must disengage the catch (3" after the catch (3 has released the collar (3 to allow the catch (3* to move immediately back to its position shown in Fig. ti. As the lever T does not allow a return movement of the lever T as long as the shuttle is in the raceway it necessary to open the catch (2 to release the catch Q from the lever T, and this is done by the shring'vu'm T. \Vhen the catch Q is moved by the lever I, the springarm T moves with the lever T, and the movement of said arm on its pivot causes the free end of the arm to push the catch (3? out of engagement with the lever T as soon as the collar (Q is released. The catch Q no \v moves to the position shown in Fig. I), while the lever T and its arm T remain in the position into which the lever was moved by the lever T \Yhen the lever T is released, then the spring-arm T returns the lever T tor T) to position to engage the catch (3. It is understood that during the time the shuttle passes through the open shed the eorrespoinling needle Q or Q is in a rear-most positionthat is, out of the path of the shuttleand the eorrespolnling eat-eh if then engages the rollar (3 while the lever T or T engages the notch T in the eorrespr'mding lever T or As soon the shuttle passes into the raceway I) or I) and presses the lever l or l outward, as before explained, then the corresponding lever T or T" is caused to swing, thereby moving the end of said lever out of the notch T and imparting a swinging motion to the lever T or T to draw the catch out of engagement with the corresponding collar Q and allow the spring (3 to move the rod or ()forward for the corresponding needle (.3 or (3' to receive the loop A",whieh is eastoll' the shuttle F on the withdrawal of the lug F". The needle Q or (3' now holds the loop A during the forward or beating-in stroke of the lay l), and when the lay I) returns on the next stroke the needle Q or Q is withdrawn by the action of: the lever S or S, as above explained, so that the needle is again out of the path of the shuttle for the latter to pass through the open shed at the next pick.
The holder for each weft-threai'l A or A is arranged as follows, special reference being bad to Fig. 1 and S: The weft-thread A or A after leaving the corresponding spool A or A passes forwardly through eyes I 1 located one above the other and held in a frame I, secured to a bracket 1?, attached to the main frame ll. A spring I is secured in the frame I and is curved to press one side of the weft-thread against the side of the frame I to clamp the thread in position for the time being. The free end of spring 1 is pivotally connected by link I with a bell-crank lever I and adapted to be engaged by a rod 1 carrying a friction-roller l in contact with the peripheral surface of a cam. U, secured on the cam-shaft U of the loom. Now by the arrangement described the weft-thread A or A is periodically clamped and held in position by the spring I and is periodically released at the time the cam U imparts a sliding motion to the rod 1 to swing the bellcrank lever l and to draw the spring I out of engagement with the thread. The thread after leaving the upper eye 1 passes through an eye B, carried on the bracket B and then the thread passes through the eye .l', mounted to slide vertically on rods .1 and J secured at their lower ends on the bracket l3 and attached at their upper ends to an overhead support 13, as indicated in Fig. 1. A spring J is coiled on the rod J to normally hold the eye J in an uppermost position, the spring permitting, however, the eye .I to slide downward on its rods J or J when a pull is erted on the thread by the shuttle passing from one side of the loom to the other. This is at the time the weft-thread is laid double in the open shed. Now as soon as the pressure on the weft-thread is released the eye J is drawn forward by its spring J to take up any slack that is in that portion of the weftthread extending from the eye J through the open shed and to the end secured in the selvage of the fabric. it is understood that when the shuttle goes through the open shed the eye J is drawn downward against the tension of its spring J, but during this time the thread is held by the spring I in the frame I to prevent unwinding of the weft-thread from its spool A or A". When the shuttle has passed through the open shed and the loop A has been cast off from the lug i and the i'zorresponding needle (3 and Q has moved in position to receive the loop, then there is some slack in the weft-thread, and this slack is innnediatcly taken. up by the spring J pulling the eye J, so that the loop A engages the needle Q or Q very firmly. Immediately after this the hook ll disengages the weft-thread, and consequently the latter again becomes slack, and this slack is also taken up by the further upward movement of the eye J caused by the spring J. As soon as the lay starts to go back after having beaten in the weft-thread then the spring I' is moved out of engagement with the warp-thread, and now the eye J moves into a final uppermost position by the action of the spring J and in doing so unwinds a portion of the weft-thread from the spool A or A The amount unwound from the spool corresponds to the amount needed in the neXl pick, it being further expressly understood that as soon as enough thread has been unwound from the spool A for the purpose mentioned the spring I" again clamps the thread in position in the frame I to prevent unwinding of the thread d u rin g the time the shuttle lays the doubledup we t't-thread in the open shed.
The operation is as follows: When the lay is in a rearmost position, as illustrated in Fig. l, and the shuttle F has passed through the open shed from the shuttle-race D into the shuttle-race l) and cast oit the loop A, then the needle Q" engages and holds this loop, so that the doubled-up weft-thread extends in the open shed and can now be beaten in on moving the lay D forward. hen this has been done and the lay moves into a rearmost position, then the needle Q is withdrawn from the loop, as previously explained, and the hook II on the left-hand side of the machine engages the weft-thread A and holds the same across the open shed at the left-hand side in such a manner that when the shuttle moves from the shuttle-race D through the open shed then its lug F engages the weft-thread A to form the loop A" and to carry the now doubled-up weft-thread through the open shed, and when the shuttle moves into the shuttle-race D the lever P is actuated to cause the needle Q to move into an active position, so as to receive the loop A as soon as the same is cast off. from the lug F. Thus the weft-thread A is doubled up in the open shed and is now beaten in on the next forward movement of the lay D. \Vhen this has been done and the lay moves back into a rearmost position, then the needle Q is withdrawn and the hook H is moved into engagement with the weft-thread A to draw the same across the open shed, so that the shuttle F on the next. movement from the right to the left carries the weft-thread along to again lay the doubled-up weft-thread in the open shed. The above-described operation is then repeated.
It understood that the several devices operate in unison to produce thedesired result. It is further understood that whatever weftthrcad A or A is called for in the pattern is moved into an active position by the corresponding hook 11 or H from a card of the jacquard. \Vhen it is desired to weave plain goods, then the device shown in Fig. {I is em ployed-that is, a single hook llor II is only used, and each hook is drawn downward by a cam U held on the cam-shaft U and engaging a lever V, connected with one end of the rope N.
By employing a spoolless shuttle and carrying the weft-threads to the shuttle from spools located outside and independent of the shuttle the weaver is enabled to control the weaving more accurately and the endless annoyances due to spools in shuttles as heretofore constructed are completely avoided.
As any desired number of weft-threads can be employed on each side of the machine and interwoven with the warp, it is evident that any desired pattern can be produced in the weave. In fact, the loom can be readily adapted for doing any kind of weaving.
Havin thus described my invention, I claim as new and desire to secure by Letters Patent 1.
