I will now proceed to describe my improved i loop-holders, the right-hand one of which is shown more clearly in Figs. 5 to 7, inclusive, in which figures the numeral 16 designates the case or shell of said loop-holder, which is suitably fixed tothe lay-beam and is open at both ends. This case or shell is formed on its upper side with the lugs or extensions 16', between which is fixed the shank of the loopholder 15, which holder is pivoted on a shaft or pin 15', supported in said lugs or projections, the loop-holder heilig arranged eXteriorly of lthe fixed shell or case, and provided at its forward end with a depending hook 17, adapted to engage and retain the loop in the weft-thread, whilethe rear end of the loopholder is provided with a depending rightangled arm 17', which is bifurcated, as shown in Figs. 5 and 7, to embrace a reciprocating plunger 18. This plunger 18 is arranged longitudinally within the iiXed case or shell 16 to slide freely therein, and at one end this plunger has an enlarged head or buffer 18', which is adapted to receive the thrust of the bulged part 13 of the needle staff or bar when the latter is returned to its normal position, and which also serves to arrest the rearward movement of the plunger, because said head abuts against the end of the case or shell. Through this reciprocating plunger is formed an axial longitudinal bore or passage 19, and transversely across the plunger, on opposite sides of its axial bore or passage, are formed recesses 19', the longitudinal bore or passage admitting of the free play or movement of the reciprocating needle bar or staff through the ri ght-hand loop-holder 15 while the transverse recesses 19', in the sides of the plunger receive the bifurcated arms 17' of the pivoted loop-holder, whereby the plunger and loop-holder are connected together and the position of the loop-holder is regulated and determined by the plunger, and the plunger is in turn operated by the reciprocating needle bar or staif to elevate or depress the hookshaped end of the loop-holder.

The left-hand loop-holder 2,0 is essentially the same in construction as the right-hand loop-holder-namely, it has an open-.ended case 21,which is fixed to the lay-beam in line with its fellow loop-holder 15, the reciprocating slotted plunger 22, and the eXteriorly-arranged loop-holder pivoted to the shell and provided with an arm 23, which iits in the slot 28' in the plunger. In the case of the left-hand loop-holder, however, the needlebar does not pass through the plunger, and hence the latter is made solid, with the eX- ception of the transverse slot 23', and the arm 23 of' the loop-holder 20 is in one piece,

instead of being bifurcated, as is the case with the arm ot' the right-hand loop-holder.,

The plungers of the two loop-holders 15 2O are operated by the impact or thrust oi' the needle to positively depress the loop-holders alternately to take into or engage with the loops formed by the weft-thread and at the termination of each back-and-forth movement' of the needle. Thus when the needle has completed its forward movement through the shed it impinges against the concave head of .the plunger 220i the left-hand loop-holder andforces-the said plunger forward to depress the hooked end of the loop-holder 2O and cause it to engage the loop in the weftthread, and when the plunger completes its return movement the bulged part 13 of the needle-bar impinges against the enlarged head of the plunger 18ofthe righ tfhand loopholder 15, which impact forces the plunger rearward with the needle-bar a short distance, which is sufficient to depress the loop-holder 15 and cause it to engage the loop of the weft-thread. The left-hand loop-holder is first disengaged from the weft thread or loop by means of an arm 50, (see Fig. 10,) which is xed to the front part of the frame 1 and in the path of the rear end of the plunger, so that when the lay is swung forward the rear end of the plunger 22 rides against the curved heel of the fixed arm, and the plunger is thus moved longitudinally and operates to lift the free end of the loop-holder 20.

The plunger of the right-hand loop-holder15 is arranged in the path of the reciprocating needle-carrier 8, and as the carrieris moved forward and the needle is pursuing its course through the shed this carrier impin ges against the rear end Aof the plu nger and forces the same forward, thereby lifting the free hooked end of the right-hand loop-holder 15, as will be readily understood. 1

The crank-shaft 4 is provided at one end IOO ITO

with the fast and loose pulleys, as is usual, and

`zontally-inclined lever 28, which lever is pivoted at a point intermediate of its length in,

a fixed bracket 29 on the frame 1, and is adapted to be vibrated on its fulcrum as the friction-roller follows the course of the groove in the cam. To the free end of this inclined lever is coupled a link 30, which has its other end coupled to an upright lever 3l, which is fulcrumed at its lower end on the lay rockshaft, as at 32. The upper free end of this upright lever 31 is pivoted to a link 33, which in turn is pivoted to a depending portion of the needle-carrier 8, wherebv the cam is connected by intermediate devices with the needle-carrier to impart a rectilinear reciprocating movement to said carrier and the needle at suitable regular intervals.`

The pivoted connections between the lergo - vers 28 and 3l and the link 30 is effected by means of loose ball-and-socket joints 33', (see Fig. 13,) in which the sockets are formed or secured on thc ends of thc link, and the balls suitably secured to the levers.

Near the right-hand end of the lay-beam is provided the thread-receptacle 35,- from which the weft-thread is led to the needle and passed through thev eye thereof; but before the weft-thread reaches the needle-eye it passes through a tension-regulating device 3S, which is preferably applied laterally to the shell or case of the right-hand loop-holder 15. Thistension-regulatorconsists ofa springarm 3S, suitably secured to the fixed shell 16 and having a friction-shoe 39 at its free end, upon which said spring-arm bears, and the pressure of the spring-arm on the thread can be regulated bythe adjustment of a thumbscrew Lt0, as shown in Figs. 5 and 7.

lt is obvious from the foregoing description, taken in connection with the drawings, that the needle-carrier is lnoved forward and backward in its guides on the lay-beam by the operation of the cam thereon through the system'of levers and links.

The weft-th read from the receptacle 35 runs or extends through an eye or guide 45 on the lay-beam, and thence extends alongside of the shell or case of the right-hand loop-holder 15 over the outer rounded surface of the lug 39 and beneath the spring 38, after which it passes to the eye of the needle. The weftthread is held under proper tension by being compressed against the lug 39 by the spring 38, which latter is adjusted by a thumb-screw 40. The right-hand loop-holder engages the weft-thread as the latter is introduced in the eye of the needle, the point of said loopholder 15 descending in front of the point of the weft-needle-that is, between the point or tip of the needle and the weft-thread when in the position shown in Fig. 3 of the drawings, and this loop-holder 15 operates to hold the weft-thread as the needle-bar moves forward through the shed and until the hollow plunger of said loop-holder is thrust forward in the manner described to raise the said right-hand loop-holder as the needle-bar completes its forward movement, and thereby release said loop-holder 15 from engagement with the loop in the weft-thread. As the needle bar completes its forward movement through the shed, the front end of said bar colnes in contact with the plunger of the lefthand loop-holder 20 which is depressed by the movement of the plunger to engage the loop of the weft-thread, and simultaneously with the impact of the needle-point on the plunger of the left-handloop-holder 2O the needle-carrier S strikes against the plunger of the righthand loop-holder 15, which plunger is operated to raise the loop-holder 15 in position to engage the weft-loop, whenon the backward or return movement of the needle the bulged part 13 thereof impinges on the head of the plunger 18 and moves the lat-ter rearward to depress the loop-holder 15 and cause it to engage the weft-loop. Just before the completion of the forward movement of the laybeam thc left-hand loop-holder 20 is raised into position to engage the next weft-loop by reason of its plunger riding against the fixed arm 011 the frame and being forced to the right by said arm.

I am aware that slight changes in the form and proportion of parts can be made without departing from the spirit orsacriiicing the advantages of my invention, andi would therefore have it understood that I reserve the right to make such modification as fairly fall within the scope of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
