AApplication filed December 6, 1909.. Serial No. 531,483.

To all whom it ma@ concern:

Be it known that I, JOSEPH J AGGER, a citizen of` the United States, and a resident of Poughkeepsie, in the county of' Dutchess and State of New York, have made certain newl and useful Inventions Relating to Jacquard Looms, of which the-following is a specification, taken in connection with the accompanying drawing, which forms part of the same.

This invention relates to Jacquard looms and relates especially to Jacquard .looms suitable for weaving velvet carpet or other fabric in which a plurality of selectively operated lifting boards'are usedin connection witlrthe usual card actuated needles to control the pattern warps.

In the accompanying in a somewhat diagrammatic manner an -illustrative embodiment of this invention, Figure 1 is a partial side elevation. Fig. 2 is a similar View, parts being broken away. Fig. 3 is an enlarged carpet section; and Fig. 4 is a plan view thereof.

In the illustrative embodyment of this' invention shown in the drawings, the head frame 1 may be mounted upon a suitable yoke 2 on the frame of the loom which may comprise a lay 46 provided with the usual reed 45 and operated by any desired means as by the batten arms 60, G2, pivoted together by the pin 61, the arm 62 being seerate soas to alternately raise the cam levers y cured to the pivot 63 carrying the arm 64. The cam 50 on the cam shaft maybe provided With'a plurality of cam grooves 53, 54 with which the cam rolls 5l, 52 cop- 77, 48 pivoted about the pin 49. It is of course unnecessary to show or describe in detail all the usual operating mechanism of theloom which may as indicated comprise the Iseries of guides 69 over which the creel warps 70 pass lto the shedding mechanism. The binder warps may pass through the guides 44 controlled by the usual binder heddles 4l, 42 and the delivery of the binder warps from their' drum 66 mayhepontrolled by any desired tension devices, such as the tension lever 71 over which the warps pass after leaving the guide -.7 3, `the weight 67 having its vrod 68 in engagement with the lever. The drum of Studer warpV may be provided with a similar tension lever 7 2and the stuffer warps after passing over the `guide 74 and tension lever mayvpass through 'jf 'the 'guide or eye 44 controlled by the stutter drawings showing heddle 40 secured by the arm 38 to the comber board 39 operated in the usual Way.

The jacquard needles 35 may be mounted in the usual wayin their guide frame 36 and may be actuated as usual by the- ,cards l16 passing over the card cylinder 29 which may` be mounted at the end of the cylinder slide 27. As this slide is reciprocated the catch 28 which is in operative position engages one of the pins 30 as the cylinder moves away from the needles so as to bring up another card from the box 15 so that a fresh card is brought into coperation with the needles when the cylinder again moves toward them. The cylinder slide may be operated by the slide lever 20 pivoted in the frame and normally drawn down by its control spring 12, the arm 19 of this lever being preferably provided with a slot 18 in which t-he pin 17 on the cylinder slide is adapted to move. -The pin 23 `in the slide lever may be raised by the coperating hand lever 24 so that the cards may be manually moved around to the desired extent. The cylinder and slide lever are however normally operated by the cylinder rod 11 pro- Y l indicated at its lower end to the lifting lever 6 mounted upon the pin 4 and operated by the lifting rod 7 from the cam lever 77 so that each time this lifting lever is completely raised the slide lever and connected cylinder slide are oscillated, althouofh this cylinder slide and jacquard cylinder are normally yieldingly held against the needles by the control spring 12.

Instead of having a single lifting board to control the harness connections 34 a pluralityof lifting boards may be employed 'which vare selectively or alternately operated. As indicated in the drawings two such lifting boards 25, 26 may be used, the back lifting board 25 controlling in this instance the even numberedv pattern warps while the harness is so tied that the front lifting board 26 controls all the odd numbered pattern warps. The lifting board 25 may be lifted by any suitable device, such as-the lifting link 9 pivoted to the lifting lever 6 and the lifting board 26 may be similarly 'raised by the connected lifting llink 10 pivoted as indicated in Fig. 1 to a single cycle.

l and operated. by the lifting rod 8 connected te the c. responding-cam lever 48 so that the two` ing boards may in this instance be alternately ised, i ing board may also in utcd as it is raised by providing thereon' the Vrolls which may when'the lifting board is in its lower position indicated inA dotted lines in Fig. 2, the

rolls engage the vertical portion of the. guide.

Under these circumstances when the loom 1s operating eachjacquard card remains in engagement with vthe needles for a number 0f picks during which time one of the lifting boards is Iirst raised and then lowered land then the other lifting board raisedf, nd

returned to its lowered position, complet ng Thus in this case one-half the desired pattern threads -throughout the width of the fabric are raised by one board to' form the patternloops andpile tufts and then thereafter the intermediate or even numbered pattern warps of similar colors are raised into the pile in the next row of the fabric. As indicated in Fig. 3 the odd numbered pattern warps may be brought up to form the loops 84 around the pile wire 75 and these loops maybe subsequentlyV severed to form the pile tufts 94;. The even j numbered pattern warps which are raised board are brought. upv in the next row of the fabric so as to form by the-'other lifting the diagonally arranged pile` tufts Slet` in the fabric 57 indicated in Fig. 4, although it is of course'understood that in the completed fabric the pattern warps forming the pile are sufficiently tufted out to constitute a practically even uninterrupted surface., v The filling threads 76 may if desired lbe so arrangedin the completed fabric that a plurality of the upper filling threads engage each pattern warp between two consecutive pile tufts to more'securely hold itin position and these filling threads are of course securely held together and upon they stufler and inoperatiffe pattern warps 76by the binder warps 90 in the usual way. -It is of course understood that after the pile wires have been withdrawn as the fabric passes over the 'support 59 shown in Fig. 2 the fabric 57 passes over a suitable guide roll 56v to be wound upon its drum and subsequently clipped and finished' in the case of cut velvets.
