Specification of Letters Patent. Patented 25, 1913,

l Application filed July 15, 1912. Serial No. 709,319.

To all whm'n'it may concern.

, Be it known that I, ARTHUR EMERY, a

i citizen of the United States, residing at Philadelphia, in the county of Philadelphia -and State of Pennsylvania, have invented an Improvement.- 1n Narrow-Ware Looms,

of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawin representing like parts.

he invention to be hereinafter described relates to narrow ware looms, and more par-.

ticularly to shuttle motions of such looms,

whereby the series of shuttles are moved to lay filling or weft in the sheds of the fabrics being woven.

As Well known by those skilled in'the art, looms of this generic character have been devised to weave a series of narrow fabrics side by side, and if desired, such fabrics me have different characters or colors of filling or weft, in which event a plurality of banks or series of shuttles are employed, and the bank or series of shuttles having the desired character or color of filling is brought into play as dictated by the pattern of the fabrics being woven; or a plurality of fabrics may be woven in vertical rela tion. In any event, the shuttles of each series are moved across the warp space of their res ective fabrics tolay the filling or weft, an various means have been devised to impart desired movement to the shuttles.

The aims and purposes 'of the present invention are to simplify, render more effective and positive, and generally to improve the means for giving to the series of shuttles the movements above-noted whereby filling is laid in the shed ofthe fabrics being woven, all of which will best be made clear from the following description and accompanying drawings of one form of such means, it being understood that the invention is not circumscribed bythe details thereof, but in its truescope is pointed out by the claims.

In the drawings :-.Figure 1 is a front elevation of one end of the loom, showing the lay or batten and its associated elements, parts being broken away. Fig. 2 is a side elevation at. the same end of the loom, showing more particularly the lay or batten, its mounting,-the actuating means lherefm',

the devices carried thereby, the latter being partly shown in section. Fig. 3 is a detached detail showing the driving con nection between the shuttle actuating shaft. and the under shaft of the loom. Fig. 4 is a top or'plan view of one end of the batten or lay, showing features of the present invention, parts -being broken away. Fig. 5 is an enlarged detail showing the action of the picker fingers,.yielding plunger,

and picker blade. Fig. 6 1s a cross-section on line 6-6, Fig. 4.

In the drawings, the loom frame 1 may be of any usual construction suitable for supporting the operative parts. Mounted on the loom frame is the crank-shaft 2, which maybe driven from any suitable source of power usual, and connected thereto is the pinion 3. to which is jointed at 4 thepitman 5, the other end of'which connected at 6 to 'a bracket 7 secured to the lay beam or batten 8., To the lower portions of the bracket 7 are pivotally connerted at 9 the links 10, whichat their lower ends are pivotally sustained, as at 11 upon the loom frame, the constrl'lction being such that upon rotation of the'crankshaft 2 the lay or batten '8 will be given a movement toward and from the front of the loom, the lay or batten during silch movement maintaining its vertical or op erative position, as will be well understood by those skilled in the art. i v

Mounted on the lay or batten 8 through the agency of any suitable means is the auxiliary batten 12, whichrcarries the series of shuttle races 13 separated by a space l t through which pass the warp threads which form the warp of one or more of the narrow fabrics being woven.

'lhe'shuttles 15 which carry the weft or fillingto be laid in the shed formed. in the warp threads, are or may be provided with the usual rack teeth 16 engaged by suitable pinions 17, as indicated in Fig. 1, which .pinions may be operated at the desired tunes. through the usual racks 18 to impart to the shuttles their prescribed or desired nnnements, through the shed of the warp threads, as usual in this character of devices. r i

- lnlhe present form of the invention there is shown three banks or series of shuttles,

and for each series of shuttles there is a separate rack 18, as indicated by Figs. 2 and 6, said racks being appropriately connected, as will hereinafter appear, to their respective pinions 17 to impart to (the shuttles the desired movement to lay the filling in the shed. v I

In the form of the invention herein illustrated, theauxiliary batten 12, Fig. 1,- is mounted upon the lower batten or lay 8 soas to have rising and falling movement with .relation thereto, and as one means to this end, brackets 19 (Figs. 2 and 1) extend upward from the rear of the batten 8 and are provided with guideways 20 which engage complemental guideways 21 secured to the rear of the auxiliary batten 12. Mounted upon the batten 8, Fig. 1 at 22, is a bell crank-lever 23, having a link connection 24 with the auxiliary batten 12, said bell-cranklever being likewise connected by a chain or other flexible device 25 with suitable pattern mechanism, not necessary herein to be described, since it. forms no part ofthe present invention. A spring 27 (Fig. 1) normally tends to lower the auxiliary batten, the construction being such that under demand of the pattern, and through the connection 25 and bell-crank 23'the auxiliary batten may be raised or lowered to bring the appropriate bank or series of shuttles into the line of the race or shed of the warp thread.

In the form of the invention shown, the narrow fabrics being woven side by side are adapted to have different characters or colors of filling laid in the shed of the respective war-p threads to vary the pattern or color effects, and through the pattern connection hereinbefore described, the rising and falling movement of the auxiliary batten determines which one of the banks or series of shuttles shall be brought into the line of the race or shed, to have its appropriate filling laid in the fabric. It will not be necessary to go further into the details of means for moving the auxiliary batten in the manner stated, because such means form no part of the. prese-nt'invcntion, and are herein shown only in so far as illustrative of one of the applications ofthe present invention, it being understood that the invention to be herein described is applicable to any character of narrow ware loom whether.

be figured or more vertical and bolt connection 31, Fig. 1. In order to effect adjustment of the brackets 30 on the plate 28 a suitable shoulder 32, Fig. 2', is preferably formed on the plate 28 and against this rest-s the end of an adjusting screw passing through a lag 34 extending from each of the brackets 30 and held in adjusted position by means of a suitable set nut. Obviously various means might be employed for connecting the brackets 30 to the beam or lay 8, but the above-described means has been found convenient as a good, practical form of such devices. The brackets SO'eXtend upward and have suitable socketed endportions35 in which are held the end portions of guide rods 36, there being referablytwo of such guide rods extending tween the brackets 30 as indicated in Figs. 1 and 2, such guide rods being held in position by suitable means such as the set screws.

37, or the like. Mounted to slide upon the guide rods 36 are the picker slides 38, said picker slides 38 having appropriate sleeve portion for engaging the guide rods 36, as will be clear from Figs. .1 and 2.

Pivotally mounted at 39 upon the batten 8 or a projection fronrthe plate 28 carried by the batten, is the picker lever +0, having an arm 41. the upper end of which is con- ,nected to the picker slide 38 by means of a link 42 pivoted to the upper end of said arm 11, and to the picker slide. Similarly pivoted at 43 to the batten S or a. projection of the plate 28-carried by the batten is the picker lever 44 connected at its upper end by a link 45 to the other picker slide 38, said link 4-5 being suitably pivoted to the lever H,- and to its picker slide 38. Projecting from the respective picker levers 4-0 and 4:4 arc the arms 4-6 and 47 respectively which are connected at their free ends by the adjustable connection 4.8, Fig. 1, said adjustable connection 49 being-preferably formed by a turn-buckle or similar device, whereby the nclation of the picker levers 40 and -l--l: may be appropriately changed as desired. in the present form of the-invention the turnbuckle :18 preferably comprises end portions oppositely screw-threaded into appropriate sockets 4D pivotally connected at :30 to the arms 46 and 47.

Frornthc construction thus far described -it will be apparent that if motion be im- Jpartcd to one of the picker levers, such motion will cause such picker levers to move around their respective fulcruins toward and from, each other so as to carry the picker slides 38 into similarly movable relation:

nections, the essential being that suitablefl.

means be provided to impart to the picker slides 3b movements toward and from each other, tor purposes as will presently appear.

livotally mounted upon each of the picker slides 38 is a picker finger 51, each of said picker fingers having a notched or jaw portion 52 (Figs. 4 and 5) which is adapted to engage, as will hereafter appear, with the end portion of a picker blade 53, suitably connected, one to each of .the racks for actuating the shuttlesj In the present form of the invention, each of the picker fingers 51 is pivotally mounted at 54-. to a lug 55 projecting reaiwardly from its slide 38, and a suitable spring, as 56, normally tends to hold the notched end 52 of the picker fingerclosed upon the face or back of the picker slide 38. In the present form of the invention, the spring 56 is shown as-coiled about the pivotal portion of the 'picker finger 51, one end of the spring being connected to the lug 55 and the other end of the picker finger, but obviously various forms of this feature of the invention might be employed, the characteristic of thisportion of the device being that a suitable yielding means normally acts upon the lingers 51 to hold them closed upon the back face of their respective picker slides 38.

Each of the picker fingers 51 has a projecting tail portion 57, (Figs. 4 and which, .as the picker slides 38 are moved into separated relation, are adapted to engage a yielding follower or plunger 58, the construction being such that when the tail portion 57 of a picker finger engages its coacting plunger,-the picker finger will be turned upon its pivot 5d and its notched portion 52 will be thrown outward from the picker slide 38, substantially into the position indicated by Fig. 5. Upon movement of the icker slides relatively toward each other, tie notched portion 52 of the picker fingers will be in position to engage the end of a picker blade 53, provided such picker blade be in position to permit such engagement, as will presently appear.

It is appropriate at this time to describe the picker blades and their. association, each with a rack 18 for moving the shuttles. Se-

cured to the upper and lower rails of the.

auxiliary batten 12 arethe brackets 59 (Figs. 2 and 4-), one of said brackets being disposed substantially opposite each of the brackets 30, hereinbefore described. Extending between and secured to each of the brackets Share the guide rods (30, three in the present t'ormof the invention, one for each of the banks of shuttles, see Fig. 2.

These guide rods (30 may be secured to the brackets 59 in any approved manner and each has mounted thereon a picker plate slide 61, said slide being preferably formed as indicated in Figs. 4 and 5, that is each picker plate slide has an end sleeve portion 62 embracing one of the guide rods 60 and a web at the rear connecting such sleeve portion 62, said web being connected in turn by an arm or plate 63 (Fig. 2) to one of the racks 18. Each of these picker plate slides carries a picker plate 53 which is less in length than the distance between the picker slides 38 when said picker slides are at their maximum degree of separation, it, being understood that there is no normal connection between the picker plates and the picker fingers or the picker slides 38. I

Fromthe construction thus far described, it will be apparent that as the picker slides 38 aremoved by their connected picker 1evers into their maximum separated Osit-ions, the tail portion 57 of each ot the picker fingers 51 will engage its coacting plunger 58 with the result that the picker finger thus engaged, will have'its notched end 52 thrown outward against the tensions of the spring 56, and should a picker plate 53 be in the path of movement of the picker finger 51 as indicated in Fig. 5', said finger 51' will engage the end of the picker plate, and uponmovement of the picker slides toward each other will carry with it the engaged picker plate, and

through the connections therewith, move the connected rack 18 and the shuttles operated thereby. On the next separating movement of the picker slides38 the picker fingers 51 when free from the picker plate will move into close relation with the slides 38 until they approach their outer positions, where' upon they will engage by their tail portions 57 their coacting plungers 58 and have their notched portions 52 thrown outward into position to again engage the end portion of a picker plate when the picker slides 38 are again moved toward each other. Thus during the operation of the loom a picker fi-nger 51 when thrown outward into the posi-,

tion indicated by Fig. 5, will engage the end of a. picker plate if such picker plate be in position for such engagement, and will move such picker plate to the other limit of the picking movement, and then leave it disconnected and free from mechanical control.

In order that the picker fingers when thrown outward into the position indicated by Fig. 5 for engaging with the picker plate may remain in said position as the picker slides again move toward each other at the commencement of such movement, the follower or plunger 58 is made yielding, so that it, will follow up the tail portion 57 and hold the finger 51 in outward position until it has engaged the end portion ofthe picker plate, should such picker plate be in position for such engagement; and thereafter, as the picker slides 38 more still tar,- ther from their outer positions, the notched portions 52 will maintain themselves in engagement. with the engaged picker plate.

being interposed between the head of the plunger and an appropriate shoulder in the adjusting sleeve 67. The plunger is also preferably Pllfl'ltlttl with a head (39 by which it may be manually withdrawn or held in retracted position in order that. he picker fingers 51 may .not engage the picker plate when it is desired to operate the loom experimentally, or for other purposes, without moving the shuttles. It will be noted that by appropriate manipulation of the heads 70 of the adj ust-ing sleeve 67, the relation of the end of the plunger 58 with the tail of the picker fingers may be properly timed and regulated.

In the present form of the invention, as hereinbefore noted, each of the picker slides 38 carries a single picker finger and the auxiliary batten 12 is raised and lowered under the pattern control to bring any one of the three or more picker plates 53 into the line of action of the picker fingers 51, the loom of the present illustration being intended for the'production of narrow fabrics having a pattern formed by different characters or colors of filling. It is to beunderstood, however, that the present inven-- tion is not restricted in its use to the particular form of loom herein illustrated, and that it may be applied as a shuttle motion in a narrow ware loom having two, three, four or more banks of shuttles or battens or to whatis known as a two-bank double deck batten. In the last-named case, two or more fabrics will be formed in vertical relation, that is in the warp space 14 there will beprovided two. or more sets of warps each set comprising the warp threads of a single fabric. In thisdast-named case it is only necessary to provide each of the picker slides 38 with an appropriate num-.

ber of picker fingers 51, so that upon reciprocating the slides 38in the manner hereinbefore pointed out, suchpicker fingers may engage with appropriate picker plates to move the shuttles and cause the filling to be'laid in twoor more fabrics, according to the number of fabrics being woven in vertical relation. For instance, in a twobank double deck batten each 92 the picker slides 38 will havetwo 'icker fingers 51 with their cooperating yie ding plungers or followers and in'the operation of such construction the upper picker finger of one picker slide will be moving a picker plate in one direction while the lower'pick v.r finger I of the opposite picker slide will b moving a picker plate in the opposite direction, that is two rows of shuttles will be moved at the same time to layv the filling in the shed ,of two separate fabrics.

From the construction hereinbefore described as one embodiment of the present invention, it will be noted that while the motion of the shuttles is positive and not dependent upon flexible connections such as chains, rawhides or catgut, each of the banks or-series of shuttles is left free from the actuating means as soon as the shuttles have mo ed in either directionto lay the filling in the shed, so that should occasion require, the shuttles may be freely moved by hand in either direction while the loom is at rest.

In view of the fact that each bank or series of shuttles when moved in the manner stated, is left free, it is at times desirable to provide-some means for preventing accidental or undesired movement of the l banks or ser1es of shuttles, and as one means 9b to this end the auxiliary batten 12 has atable depressions or sockets in the picker plates 53 near the end portions thereof, as indicated in Fig. 6. These plungers are normally-acted upon by the springs '75, Fig. 6, the construction being such that when one of the picker plates is moved tothe limit of its stroke in either direction, one of the plunger-s will engage the depressions or socketed portion in the end ofthe plate, as indicated in Fig. 6, and yieldingly maintain the picker plate in the position to which it has been moved and Where it is left by the picker finger. Obviously various forms of means might be provided for preventing this accidental movement of the picker plates, and it is to be understood that the invention is notlimited in this respect, although the form shown and described is found to be of convenient construction. I

In order to effect the movement of the picker slides 38 toward and from each other in the manner hereinbefore noted, the present invention contemplates the actuation of the picker levers .by positive connection with the under-shaft of the loom, or with the crank-shaft. To this end the batten 8 has secured to and projecting downward therefrom, a bracket 76, Figs. 1 and 2, thelower portion of said bracket 76 having-a bearing 77 fora crank-shaft .of an adjusting screw 82 threaded through the said crank pin slide and having its other end provided with collars 83 to engage between them suitable'lugs 8i projecting from the crank arm, the construction being such that upon manipulation of the adjusting screw 82 the crank pin 81 may be moved to or from the end of the crank arm.

Connected to the crank pin 81 is the adjustable pitmaii 85, said pit'inan being preterably formed of two parts, as indicated in Fig. 1, and having a right and left screw connection as at 86 whereby the length of said pitmaii may be varied," Said pitinan is connected at 87 to the lower arm of the picker lever 40, the constructionbeing such vthat upon rotation of the crank-shaft the picker levers will be operated to move the picker slides toward and from each other in' the manner hereinbefore explained.

Secured to the under-shaft 88, 1s a bevel gear 85.), Figs. 1 and 3, which meshes with a corresponding bevel gear 90 splined to the shaft 91 as will be clear from Figs. 2 and 3. The shaft 91 is connected to the crank-shaft 78 by a universal joint 92, the construction being such that as the lay or batten 8 moves toward the front and rear of the loom, the shaft 91 will'slide lengthwise through the bevel gear 90 and the universal joint 92 will act to prevent any binding 'and facilitate ease of rotary motion of the crank shaft.

' In order that the rise and fall of the batten or lay'8 may findcompensation in the connection of the crank with the under-shi'it't, the under-shaft- 88 has mounted thereon a loose sleeve 93 (Fig. 3) connected by a web 94 with a similar sleeve 95 on the shaft- 01, the construction being such that as the-bat.- ten or lay 8 rises and falls in its arc of movement toward and from the front of the loom, the connected rocking sleeves 93 and 95 will rockabout. the axis of the under shaft 88 and thus compensate for this rising Y and falling movement of the lay.

While the present invention has been illustrative in connection with a particular type of narrow Ware loom, it is to -'be understood that it is a general application and not restricted thereto; indeed, this appears to be the first case in the art wherein a.bat

ten or series of shuttles of a narrow ware loom are given positive movement froman.

actuating means and then left free to be moved by hand. if desired. The, present iiivention 1s also generic with respect to the picker fingers and their characteristic operation in connection with the picker plates, and while these parts have been illustrated and described ascoinprising certain constructions, it is to be understood that the invention in its true scope is defined by the claims. and not necessarily restricted to the details shown and described.
