Specification of Letters Patent.

Patented Jan. 1, 1907.

4 Application filed July 26, 1904. Serial No. 218,193.

' Be itknown that I, HOVCEP SARAFIAN, a citizen of the United States, and a resident of Yonkers, in the county of Westchester 5 and State of New York, have invented a new and Improved Pile-Fabric Loom, of which the following is a full, clear, and exact .de-

scri tion. T e object of the invention is to provide -:o a new and improved loom for weaving pile fabricssuch, for instance, as are shown and described in the Letters Patent of the United States, No. 752,712, granted tome February 23, 1904, and in .the Letters Patent of me February 7, 1905.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter then pointed out in the claims.

'A practical embodiment of the invention is represented in the accompanying drawings, forming a art of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of a loom embodylng my im rovements, parts nonessen tial for the un erstandingof the invention.

being omitted. Fi 2 is an enlarged-longitudinal sectional e evation of the improvement. Figs. 3 to 9', inclusive, are like views of the same, showing the parts in different positions. Fig. 10 is an end elevation of the shogging-combs, the guideways, and needle. Figs. 11 and 12 are like views',of the same, showing the parts in difierent positions.

fabric woven by the loom. 4 The pile fabric to be woven by'the loom and; illustrated in Fig. 17 consists, essentially, of sets of warp-threads a, b e, the sets being bound together by alternating'weftthreads d d, and each set ofwa -threads comprises a pile warp-thread a and W at I pre-g fer. to call an upper ground warp-thread between 't e ground warp-threads 'c and b to the United States, No. 782,178, granted .to

and

hand a lower ground "warp-thread c, thewarp-thread b. The successive bottom loops a and a of the form a-pile-loop a" above the upper ground I ile war -thread or around the lower groun warp-t ead c extend alternately in opposite directions, and the ground warp-thread b asses under the weftthread (1 in front oft e pile warp-thread a and over the weft-thre'ad d in the rear of the pile warp-thread a, and the ground warpthread a asses overthe weft-thread (1111 the rear o the pile warp-thread a and under the weft-thread d in front of the pile Warpthread a, as plainly shown in' Fig. 17.

In order to produce the weave described, it necessary to mani ulate' the warpt hreads a, b, and c of each manner and relative to each other, and for this purpose a special device resently to be described in detail, is usedff I set in a peculiar The warp-beams for the warp-threads c, b, x

and c and the breast-beam for the Woven fabric are suitably arranged on the main frame A of the loom, andin this frame is journaled a crank-shaft B, having its crank-arms B" connected by pitman B with the lay C, fulcrumed at O in the main frame A and pro% vided with the usual reed (-1 for beating in the weft-threads (Z d and the pile-wires D D. In practice the ground warp-threads b and c are preferably on a single wa beam, and thesaid ground warp-threads and c after leaving their war -beaIn are engaged by the usual heddles E F, respectively, as plainly shown in Fig. 2, and the said ground warp threads 6 c then pass-'between the shoggingcombs F F, extending transversely and having their teeth in vertical alinementiand ar ranged toward each other, as plainly indicated. in Figs. 10-12; The ground warp-threads b c after leaving the combs F F pass between spaced dents or bars ,G G which, 3 with the needle H for the pile wa -thread, are preferably mounted in a frame having anupand-down sliding movement. The said ground Warp threads b c after leaving the, I

bars G G pass-through the reed C of the lay C. The pile warpthread a, after leaving its Warp-'b.eampa sses through the eye H of the needle H, extending between adjacent bars I G G in such a manner that the needle H is approximately spaced midway between the bars and extends upwardly from the bottom .of the frame I to approximately about half,

the height of the bars, so that the'upper portion of the bars is free for both the ground warp-threads b and c to pass into simultaneously, as indicated in Fig. 10. -The pile warp-thread aafter' leaving the 'eye H. passes through the reed C with the ground warp-threads b and c, .as plainly shown in Fi s. 2 to 9.

. t is understood that a pair of bars G G form a'guideway for the passage of the ground warp-threads b and c, and the needle H, cartion of the guideway is complete y unob' structed by the needle H, and hence the ground warp-threads b 0 can be readily shifted in the guideway in a transverse direction I understood that for practical reasons I pre-' by the action of the combs F F and at the time the said guidewayis in its lowermost position and the ground warp-threads b and 0 range in the upper unobstructed portion of the guideway, as shown in. Figs. 6 and 9-.

The needle II when in an uppermost posi tion extends with its eye H above the then uppermost ground warp-thread b or c, and w en the needle 11 is in a lowermost position its eye H is below the ground warp-thread c, as will be readily-understood by comparing Figs. 2 and 9, for instance. The guideways may be stationary and only the needles moved up and down to bring the ground warp-threads alternately to opposite sides of the needle by 'shogging the ground warpthreads I) and c, as will hereinafter be more fully described, and hence I do not limit myself to the exact construction shown, it being fer to attach the bars G G and the needles H to the same frame and move the latter up and down instead of holdin the bars G G stationary and moving 0 y thev needles H up and down.

The frame I, carrying the needle H and the bars G G, is mounted to slide up and down in suitable guideways A A, arranged on the .main frame A, and the said frame I is pivotally connected at its upper end by links I with a bell-crank lever I fulcrumed at or near its middle on the main frame A, and the said bell-crank lever I is pivotally connected by a link I with the upper end of a cam-lever J fulcrumed at or nearits middle at J on the main frame A. The camlever J is provided with a friction-roller J engaging a cam K, secured on the cam-shaft K, driven by suitable gearing from the main driven shaft L, which by the usual gearing (not shown) also rotates the crank-shaft B. The lower end of the By terframe I is connected by links I with a rope I extendin under a pulley I and connected with the ower end of the cam-lever J, so that when the loom is in operation and the shaft K is rotated then the cam K imparts an intermittent swinging motion to the cam-lever J,

which by its connection with the frame I moves the latter intermittently up and down. The-cam K is so arranged that the frame I is moved whenever the lay O is in a forward position. y

The combs F F are shogged or causedto move intermittently in a transverse direction, and for this purpose a mechanism is provided connected with the main shaft L.

The combs F F aremounted to slide transversely in suitable bearings arranged in the main frame A, and the said combs F F are pivotally connected by links N and N (see Figs. land 13) with arms N and N secured on the upper ends of vertically-disposed shafts N N journaled in suitable hearings on the sides of the mainframe A, as plainlyindicated in Fig. i 1. On the lower ends of the shafts N N are secured arms N N carrying friction-rollers N N, of which the frictionroller N engages a camoove on the cam O,

secured on the main sha t L, and the frictionroller N engages a similar cam-groove on the cam 0, also secured on the main shaft L. The cam-grooves on the cams O O are arranged in opposite directions, as plainly indi cated in Fig. "1, so that when the loom is in 0 eration'and the main shaft L is rotated t en the cams O O impart simultaneously a swingin motion to the'arms N N, so that the shafts impart a transverse sliding motion to the combs F F by the links N N. The cams O and O are so arranged relative to the cam K Ioo % N are turned and their arms N N Y and the lay C that the combs F F are shifted periodically relative to the guideway formed y the bars G G.

From the foregoing it will be-seen that the combs F F are adapted to be shifted transversely in opposite directionsthat is, when the comb F moves in the direction of the arrow as (see Fig. 10) then the comb F moves in the direction of the arrow 00', and when the comb F moves in the reverse direction of the arrow 01; then the comb F moves in the reverse direction of the arrow as.

When the combs F F are in theposition shown in Fig. 10, the ground warp-thread b lies adjacent to the inner face of the bar G and the ground-warp 0 lies adjacent to the inner face of the other bar G", and when the on opposite sides'of the needle tocross the ground warpthreads b and c at the time the needle is in one of its raised positions.

Although I have shown and described two combs F F for. shifting the ground warpthreads transversely in opposite directions,

this particular construction is not essential, as only a single comb, may be used for shifting the ground warp-threads, c, for instance; but in this case it is necessary to give more movement to the comb, and hence for prac-' tical reasons I prefer to use two combs, soas to divide the'shifting movement equally to the two ground warp-threads b and c. It is also not essential 'thatthe'combs F and F be located'between the heddles E and E and the lay C, as the combs F and F may be arranged in the rear of the heddles. In the drawings the heddle E for the ground warpthis arran ement is not of particular moment I dle.

thread a is shown as the front heddle; but

as the he dle E- may be made the front hed- Various forms may be given to the needle H and the bars G G ,as indicated in Figs. 14, 15, and 16, Hence I do not limit myself to the particular construction shown, it being understood, however, that the needle H extends between two bars G G, so that the.

ground warp-threads I) 0 can pass alternately on opposite sides of the needlev while :between the bars G G, as previously explained, it being expressly understood that the main object is to loop the pile warpthread' a,

aroundthe ground warp-thread c alternately in opposite directions to form the bottom loops a and a and to pass the pile warpthread a-up between the two ground warpthreads I) c to form the face-loops a, as above set forth.
