Generally the invention relates to novel and useful-improvements in the construction and consequent mode of op ration of bullionfringe loom apparatus of the type capable of producing simultaneously a number of widths of fringe by having groups of warp threads spaced apart and weft threads adapted to be interwoven respectively with each of said groups of warp threads. In such looms it is customary to mount the hooks on the lay and to move all the hooks by positive actuating mechanism carried on the lay and partaking of the swinging of the lay.

The invention relates particularly to a driving and connecting mechanism affecting the lay and a member of the hook operating mechanism such that the backward and forward mot-ion of the lay directly, without the interposition of cumbersome and power- 9 consuming gearing and other motion communicators and converters, actuates the hook operating mechanism to reciprocate longitudinally of the lay and at the/same time to partake of the swinging movement of the g; lay.

It is the general object of my invention to improve the construction of a loom of the character described by means already mentioned and to be specifically described hereinafter such that it becomes capable of operatat very high speed with a minimum of vibration. V V

A further and incidental object of my invention resides in the'structure of the driving and connecting mechanism affecting the lay and a. member of the hook operating mechanism on the lay such that control, adjustment, actuation and timing or synchronization of the hook operating mechanism in coaction with the lay is more readily and simply accomplished and such that the parts may be more easily constructed and more readily accessible for repairs.

'1 iese objects and other advantageous ends in the arrangement and combination of parts to which my invention relates are now to be described, reference being had to the accompanying drawings, wherein like reference characters designate corresponding parts throughout all the views.

Fig. ll 18 a top plan View, partly in section, of the loom shown in Fig.

Guide rods 3, only one of which is shown in the accompanying drawings, each similarly spaced and secured onpositely tothe upri ht offrame 1, serve as the mount for lay a. The said lay liS provided with sleeved bores 5 through which pass guide rods 3,'the latter serving as bearing shafts for the lay when it is actuated to oscillation. Guide rods 8 are deviations from the usual manner of mounting the lay piv- I otally from the frame of the loom, and effectuate or confine oscillation of the lay in the intimate relation between vibratory phenomena and the action .of divers physical forces on any particular body, it can be said at this time that the mounting of lay don guide rods 8 as above described contributes in the arrangement and combination of parts of my invention toward the minimization of vibration of the frame of the loom, especially where the loom operates at high speed, and toward the functioning and operation of the driving H of the accompanying drawings. lVefts 9,

each arranged adjacent to the warp threads for every width of fringe, constitute the material r the strands of bullion in the manufacture of the various fringes. The warp threads actuated in the customary manner for the production of sheds by heddle frames 10', the operating means for the heddle frames not being illustrated in the accompanying drawings. ll efts 9 are similarly actuated by a heddle frame, not shown in the accompanying drawings, to raiseand lower them in and out of the path of a hook passing through each warp shed in a manner and for a purpose to be hereinafter described. we

Bar11is slidably mounted on lay 4i, and secured thereon by means of uprights are weft-inserting members or hooks 12' spaced between each two of the adjacent warp thread groups 8 to engage the weft for the respec:

tive warp thread groups. Lay 1 is moved to produce the beat-up of the weft, and more particularly in its application to my invention, to directly actuate slide bar 11 to reciprocate longitudinally of the lay. Lay 4 is moved for these purposes by any suitable means such as a connecting rod 13 which is actuatedby a crank pin 9 positioned in a slot 14 on a variable speed driving toothed wheel 15. 'loothed wheel 15 is secured to the main shaft 16, and derives its motion from the main drive by pulleys or gears not illustrated in the accon'ipanying drawings.

Proceeding now to description of the features of the driving and connecting mechanism inclusive of structural details, co-oporation, combination, and arrangement of the several parts, reference is had to Figs. IILVI inclusive, of the accompanying drawings.

17 and 18 are appropriately shaped guide rods secured to brackets 19 and 20, both the latter being attired to an upright of frame 1 and the breast beam 2 respectively, the said guide rods being s positioned together as to comprise a cam groove to engage grooved wheel 21. mounted on spindle 22, the latter being secured to and near the extremity of slide bar 11. dle

23 is aroller revolvably mounted on spin- 22 and'positioned above groovedwheel21,

the said roller running along a longitudi; al

guide-way. 25 is a bracket forwardly and horizontally flanged and supported by no- .rights 26, the said bracket 25 being provided on the flange withrectilinear slot 28 to serve Grooved wheel 21 is revolvably.

as the aforementioned hide-way for roller 23. 'Slot 28 is of a length equal to the longitudinal displacement of grooved wheel 21 by virtue of its engagement with guide rods 17 and 18, the extremities of the slot being in line with the thrust limits of the said guide rods 17 and 18.

In order to permit revolution of grooved wheel 21 in the cam groove, suflicient clearance is provided as best illustrated in Fig. 111 of tie accompanying drawings. VJ'hen slide bar 11 is actuated to oscillate in the right direction, grooved wheel 21 rolls along guide rod 1'? as a track and partakes of the longitudinal displacement effected by the shape of the said guide rod 17." The reactive force of thesaid guide rod 17 force grooved wheel 21 andslijde bar 11 to which it is secured to move to the right and longitudinally of lay 4:. On the return movement in theoscillation of slide bar 11, grooved wheel21 rolls along guide rod 18 forcing grooved wheel 21 and the slide bar to move to the left and longitudinally of the lay. And further to effect revolution of roller 23 in the guid eavayor slot28, slight c'learance is provided in the width of the said slot, as

illustrated in ill of the accom an in drawings. 4 I I In reference to guide rods 17 and 18 comprising the cam groove for grooved wheel 21, appropriately shaped rods may be employed to control amplitude anddiflerential timof slide bar 11 in its-reciprocation longitudinally of thelay, it being evident that for the portion of the cam groove that forms the more acute angle with the line of the horizontal, slide bar 11 will travel the faster, and'that for the portion of the cam groove that is pendicular to the line of the horizontal, slide bar 11 will not reciprocate or oscillate at all.

strands therefor. Usually, sin ultaiieonsly with the formation of the respective bull on strands, the beat-up of wefts 9 inthe respective warp thread groups 8 is produced by reeds 7 laterally secured to standards 6, the latter being alfixed to lay 4-. A knocking device, which is not illustrated in the accomp'anying drawings, disengages the respective bullion'str'ands from hooks 12 ata'bout the sametime. Thus it is manifest that alag at this point regardlessof the, reciprocating speed of lay 4 is salutary. here a certain variety of weft requires a twisting mecha nism to twist the bullion stands, this operation is done before the knocking device comes into play. A twisting device is not illustrated in the accompanying drawings, nor is the mechanism for rolling the respective but lion-fringes illustrated in the accompanying drawings. The advantages of guide rods 17 and 18 comprising the cam groove in reference to the minimization of vibration and th increase in the number of picks per unit time will be set forts hereinafter.

The operation of the foregoing driving and connecting mechanism comprising the improvements of my invention as to structure, co-operation, combination and arrangement of parts, is fairly simple. Variable speed driving toothed wheel 15 communicates reciprocating motion to lay l by connecting rod 13 which is actuated by adjustable crank pin 9 positioned in slot 14- to regulate the amplitude of lay 1. Lay 4 reciprocates in the plane of the horizontal sliding about guide rods 3. The reciprocation of lay 1 actuatesthe reciprocation or oscillation of slide bar 11 thereon longitudinally of the lay by virtue of grooved wheel 21 engaged by a cam groove comprised of guide rods 17 and 18. The operation of hooks 12 actuated by slide bar 11 to en age and carry respective wefts 9 have been heretofore described. The coaction between lay 1 and slide bar 11 is perfectly synchronized by virtue of structure irrespective of frequency in the oscillation of lay 1. Such synchronization or timing is significant; for at one limiting position of lay 4 hooks 1 function to engage respective wefts 9, and at the other limiting position,

reeds 7 produce the beat-up of the respective wefts, while a knocking device almost simultaneously therewith disengagesv the bullion strands from the respective hooks 12. If a twisting mechanism isemployed, hooks 12 are twisted the instant before th disengagement of the bullion strands by the knocking device. For high frequency of lay a a twisting mechanism is not employed; such 7 a. device bein unnecessary for certain va rieties of weft.

By the utilization of means other than the driving and connecting mechanism as heretofore described, synchronization between lay 4 and slide bar 11 is precarious when the bullion-fringe loom apparatus operates at higher speed. Under such circumstances slide bar 11 is actuated to oscillate by mechanisms comparatively unassociated with lay i such as cam-operating treadles, springs in conjunction therewith gearing and other motion communicators and converters. The said mechanisms usually interposed, as above-mentioned, to actuate slide bar 11 to synchronize with the movement of lay a are power-consuming, massive and vibratory, the functioning thereof at high speed for purvention. ing a complex structure of a complex bulposes of synchronization being influenced by friction,-dislocation, jamming and inertia of the several parts. The mechanisms for actu ating slide bar ll, moreover, are productive of vibratory movement, and the same is communicated to frame 1 of the bullion-fringe loom to which they are secured.

The quality of the manufactured fringes is seriously impaired by the vibration ofythe operative parts of the loom apparatus in the production of the said fringes. My improved driving and connecting mechanism comprises features doing away with this vibration at both low and high speed in the particulars heretofore set forth and also in the functioning of roller 23 associated with slot 28. Roller 23 prevents angular backward and forward'tilting displacement of slide bar 11 in the groove of lay 4, and prevents jamming of grooved wheel 21 in the cam groove during operation.

- From the foregoing description, the im-' proved driving and connecting mechanism afi'ectmg lay 4: and a member of slide bar 11 comprises a minlmum of simple and inexpensive parts, the latter being easy of adjustity of fringe- Vibration of the loom has been set to a minimum for both low and high speeds by virtue of all of the foregoing features present in the invention. 7

Economically, less power is consumed, less noise is generated, the production is manifoldly increased, and the bullion-fringe loom apparatus becomes more simple and comprises fewer parts, all by virtue of 'my'in- The attendant is freedfrom faclion-fringe loom.

I wish it understood that the embodiment of my invention is solely for purposes of disclosure herein and that there is no limitation to any specificconstruction in the disclosure; minor changes in size, shape and arrangement of parts, variations and'modifications of details may all be resorted to without departing from the spirit of my invention nor enlarging its scope within the appended claims.
