form openings to receive the weft-wires, which may be inserted by hand or automatically, the especial object of the invention being to provide an efficient and durable machine of this class capable of operating at a satisfactory speed. In securing this result I employ a pair of crimping-rolls provided with'teeth arranged to crimp all the warp-wires alternately in opposite directionsand to crimp the adjacent warp-wires in opposite directions, so that the weft-wires inserted when the shed is opened willbe held in the closed loops formed by the upward and downward crimps in adjacent warp-wires when the shed is closed. connection with these crimping rolls and suitable means for raising and lowering the warpwires alternately to open and close the shed my complete machine in its preferred form includes guiding-fingers between which the warp-wires pass, which fingers are formed so as to provide guides for the weft-wires, insure ing their proper position when inserted, these guiding -'fingers being withdrawn when the weft-wire has been inserted and the fabric is to be advanced.

In addition to the above features of the crimping-rolls and the weft-wire guides the invention includes various combinations of' parts and features of construction in an organized machine of the general class above described. E

For a full understanding of the invention a detailed description of a construction embodying all the features of the same in their preferred form will now be given, in connection with the accompanyingdrawings,'formingpart of this. specification, and the features forming the invention will then be specifically pointed out in the claims.

In the drawings, Figure 1 is a side elevation of the machine. Fig. 2 is a plan view of Fig. 1. Fig 3 is a vertical sectional view taken on the line 3 3 of Figs. 2 and 4. Fig. 4 is a sectional end view taken on line 4: 4 of Fig. 1. forming fingers.

Referring to said drawings, A A are the side frames, in which is mounted a drivingshaft B, which may be driven from any suitable source of power. Mounted in the frames A A above the driving-shaftB is a cam-shaft C, driven from the shaft B by gears D E. The warp-wires 00 are led from a series of spools F, mounted on the shaft 10, journaled insupports 11, secured to the frames A A of the machine, over a roll, as 12, thence through guide-grooves 13, formed in a bar 14, secured to the side frames of the machine. The grooves 13 guide the warp-wires to the pair Fig. 5 is a detail view of the shed of crimping rolls G H, arranged one above the other, the crimping-rolls G H in the form shown consisting of a number of disks 15 16.

-The disks 15 16 are provided with conicalshaped teeth 1 2, respectively, meshing one with the other, thedis'ks being secured to shafts 17 18, journaled in brackets 21, secured to the frames A A. i g

The journal-boxes19 20 are adjustable one to the other by means of suitable adjusting screws 22 for the purpose of giving a greater or less crimp to the wires while the wire is being drawn between the said crimping-rolls by suitable winding-up devices, as hereinafter described. It is necessary that. the crimps in each alternate wire should bear a proper relation one to the otherthat is, the higher portion of the crimp in one wire should be opposite the lower portion of the crimp in the alternate wire or wire next it. To provide for this, the teeth 1 2 of each adjacent disk 15 16 are staggered that is, a tooth 1 of one of the disks 15 will be positioned so as to be in line with the space between two of the'teeth 1 of the next or adjacent disk 15 the teeth 2 of the disks 16 being arranged in a similar manner, as shown in Figs. 2 and 3.

The crimping-rolls G H may be rotated in any suitable manner, the means for rotating said crimping-rolls as shown in the drawings consisting of a ratchet-wheel 23, secured to one end of the shaft 18 of the crimping-disks 16, the ratchet 23 being engaged by a springpressed pawl 24, pivoted in the upper end of a two-armed lever 25 26, loosely mounted on the shaft 18, the lower arm 26 of said lever being connected by a link 27 to a cam-lever 28, pivoted to the frame of the machine at 29 and carrying a roll 30, which engages a camgroove 31 in a cam-disk 32, carried by the shaft C, the cam-gr0ove 31 being so formed as to actuate the lever 28, and thereby the pawl 24, twice for every revolution of the shaft C, the amount of rotation given the crimping-disks 16 being adjustable by means of holes 33 in the arm 26 of the pawl-lever and holes 34 in the cam-lever 28, which are entered by the pins 35 36 of the link 27. The upper crimping-disks 15 are driven from the shaft 18 by means of a gear 37, secured to shaft 17, and gear 38, secured to the shaft 18 of the crimping-disks 15 16, respectively.

The warp-wires w as they pass from between the crimping-rolls G H are engaged by shedforming devices, from which they pass to suitable guides where the weft or cross wires 1 are inserted. The shed-forming devices consist of two bars 40 41, mounted in guideways in brackets 42, secured to the frames of the machine. The bars 40 41 carry upwardly-projecting fingers 43 44, formed integral with or otherwise secured to the bars 40 41, the lingers 43 44 being provided with openings 45 46, through which are passed the crimped wires .12, (see Fig.3,) the bars 4041 being raised and lowered alternately to form the shed and allow of the insertion of the cross-wires y in the following manner: The lower edges of the bars 40 41 have formed integral or otherwise secured to them downWardlyprojecting arms 47 48, to which are connected the ends of cam-levers 49 50, fulcrumed on the bar 51 carried by brackets 52, secured to the frames of the machine. The

cam-levers 49 carry rolls 53 54, which engage cam-grooves 55 56, formed in either side of cam-disks 57 58, carried by the shaft C. The cam-grooves 55 56 are similar in form and adapted to actuate the cam-levers 49 50 to raise and lower the bars 40 41 alternately once for every revolution of the camshaft C. The bar 40 as shown in Fig. 3 is in its raised position and the bar 41 is in its lower position, thereby separating the alternate warp-wires m as is usual in this class of machines, thus forming the shed through which is passed, by hand or otherwise, the

cross or weft wire y.

As the fabric in some cases will be of con 'siderable width, it is desirable to provide means for guiding the weft-wire y with certainty in relation to the warp-wires as the weft-wire is inserted. To accomplish this, a guideway 3 is provided in the upper part of a vertically-sliding bar 60, adjacent to the shedforming devices, the guideway 3 being formed in lingers 4, integral with or secured to the bar 60. The spaces between the lingers 4 form slots or guideways 5, (see Fig. 4,) running at right angles to the guideways 3, and these guideways 5 act to guide the warp-wires a: as the bars 40 41 move the said warp-wires vertically. The guideways 3 in the lingers 4 are flared or bell-shaped at the end at which the weft-wire 1 enters, as shown at 6, (see Figs. 2 and 4,) thereby facilitating the entrance of the weft-wire into the guideways 3. Above the bar 60 a stationary bar 66 is mounted in the frames A A, this bar having fingers 7 cooperating with the lingers 4 of the bar 60 to close the guideway 3 at the top when the bar 60 is in its upper position. They also act to guide the warp-wires when the warp-wires are moved upward, as before explained.

The weft-wire is inserted while the bar 60 is in its upper position, and after the weftwire has been inserted the bar 60 is lowered to withdraw the lingers 4 from the wires, so as to permit the fabric and warp-wires to move forward, when the bar 60 will be raised into its former position for the reception of another weftwire. The means shown for raising and lowering the bar 60 are as follows: The bar 60 has a downwardly-cxtending arm 61, to which is connected one end of a camlever 62, the other end of said lever being fulcrumed on the bar 51. The lever 62 carries a roll 63, which engages a cam-groove 64, formed in a cam-disk 65, the cam-groove being so timed as to actuate the bar 60 twice for every revolution of the shaft 0, the bar 60 be ing suitably guided in the brackets 42.

The fabric is drawn forward after a weftwire has been inserted by toothed feeding disks or rolls 68, acting to aid the pushing action of the crimping-disks 15 16. The disks 68 are secured to a shaft 69, mounted in brackets 70 on the frames A A of the machine, and the fabric is shown as taken up, as usual, on a reel 1 on shaft J. The shafts 69 and J may be driven in any suitable manner to draw olf and reel up the proper amount of fabric as the warp-wires are released from the crimping-rolls, the means shown being slip-belts 71 72 and pulleys 73 74, the belt 71 being driven by pulley 75 on the cam-shaft C.

If the wires forming the fabric are of large size and it is not desirable to reel it, the fabric may be fed or drawn along and cut into sheets of the desired lengths, the crimpingrolls G H allowing the feeding-disks 68 to draw off the completed fabric.

A general description of the operation of the machine thus organized is as follows: The warp-wires are drawn from the spools F by the crimping-rolls G H, the crimping-rolls being rotated to draw off the proper amount of wire 00 by means of the ratchet 23 and pawl 24, which are actuated from the cam 31 and levers 25 and 28. As the crimping-rolls are as to place the higher portion of the crimp formed in one wire opposite the lower portion formed in the adjacent wire. The crimped wires pass to the shed-forming devices, wh ere they are separated by means of the shed-forming bars 40 41 at the proper time by meansof the levers 49 5O andcams 56. From the bars 40 41 the wires pass through the guidingfingers 4 of the bar 60, where the weft or cross wires y are inserted. The shed-forming bars 40 41 now reverse their position--that is, the bar 40 will be lowered from the position shown in Fig. 3 and the bar 41 raised, wrapping or binding-the warp-wires around the cross-wires.- While this movement of the bars 40 41'is taking place the bar 60, carrying the fingers 4 and guideways 3, will be lowered, so as to allow a free passage of the fabric, by means of the lever 62 and cam 64, when the crimping-rolls G H will again be actuated to feed and crimp the wires and at the same time the drawing-off disks 68 and the reel I rotated by means of the slip-belts 71 72to draw 0H and wind up an amount of fabric equal to the feed of the crimping-rolls G H. The bar will now be raised again to the position shown in Fig. 3, when another weft-wire may be inserted and the operation of the crimping-disks and shed-forming devices be repeated.

-The weft-wires y are shown as put in at every fourth crimp; but it will be understood that this will be varied according to the fabric required, and a weft-wire may be put into each crimp or as often as desired, the attendant simply inserting a weft-wire when the shed is opened and the bar 60 raised, or not,

according to the spacing of the weft-wires desired. I
