LEOPOLD FUCHS, OF ROSLYN HEIGHTS, NEW YORK.

SUPPORT FOR LOOM HARNESS.

Application filed August 10, 1922. Serial No. 580,938.

To all whom it may concern:

Be it known that I, LEOPOLD FUCHS, a citizen of the United States, residing at Roslyn Heights, in the county of Nassau and State of New York, have invented certain new and useful Improvements in Supports for Loom Harness, of which the following is a specification.

The present invention has to do with improvementsin loom apparatus, and in particular to novel supporting means for loom harness, as specially adapted for use in conjunction with fancy weaving or jacquard mechanisms in whichthe harness is connected to horizontally operating or reciprocating actuating devices, such as shown in my prior patent for improvements in jacquard mechanisms for looms, No. 1,214,449, dated January 30,1917.

My invention has for its primary object the provision of means whereby the harness cords for weaving either wide or narrow ware may be so arranged as to maintain a spaced non-crossing or intersecting relationship, to thereby eliminate the wear incident to the chafing occurring in the usual arrangements, and the complicacy of inter lacing of the many cords which requires expert labor in the process of preparation for weaving operations. In other words, in the use or application of my invention, I am able to dispose the series of cords which are operated by any one of a horizontal row of griff bars in such relation to those of the next or adjacent row that they will lie in separate or spaced vertical planes, and to in this manner provide just as many of such vertical series as may be desired within the capacity of the harness actuating instrumentalities, without such cords crossing or interfering with one another.

A further object in view is to provide for the arrangement of the harness cords into distinct groups, as when weaving a plurality of fabrics, and the adjustment of any one group as a unit with relation to another group to best position the individual harness cords to accord with the width of the fabrics to be woven.

A still further object in view is to provide means for raising or lowering the harness cords, for varying the spacing between the cords with respect to their vertical series, and to adjust the vertical operating portions of the cords with relation to the batten of the loom.

My invention embodies further novel means cooperative with the harness cords whereby groups of the same may be shifted one' with respect to the other, depending upon the width of the material which is to be woven, so as to best fix in relation to the prescribed spaces of the batten.

These and such other objects as may hereinafter appear are .attained by the novel construction, combination and arrangement of parts to be hereinafter specifically described and claimed.

Reference will now be had to the accompanying drawings forming a part of this specification, wherein:

Figure 1 is a view in end elevation of my particular improvements applies to a. Jacquard loom, such as when weaving a plurality of fabrics.

Figure 2 is a vertical sectional view showing one of the supporting frames for the harness cords in elevation, a portion of the spacing wires or members for the respective harness cords being omitted.

Figure 3 is a vertical sectional view through one of the supporting frames.

Figure 4 is a sectional view taken about on the plane indicated by the line 4:4.- of Figure 3.

Figure 5 is a perspective view of a novel compass board used with my invention.

Figure 6 is a detail view of one of the removable spacing bars employed in the compass board.

Throughout the following detailed description, and on the several figures of the drawing, similar parts are referred to by like reference characters.

Referring to the drawings, A designates the loom frame which preferably includes their position transversely arranged bars or I-beams B,

upon which the main feature of my apparatus is supported, as will be hereinafter described. Projecting laterally from the frame A of the loom are the supports C upon which the supporting frame D for the griff bars is mounted, such mechanism being clearly disclosed in my prior patent above mentioned. In the sup ort D are positioned in horizontal rows a plhrality of griif bars E, terminating in hooks with which the harness cords Fare connected. These respective grifl' bars are actuated by means of horizontally reciprocating griff frames G, so as to give rising and falling movement to the warp threads of a fabric. It is unnecessary to describe this type of jacquard mechanism, which is well known in the art, it being suflicientto indicate that the positioning of the harness actuating members horizontally necessitates provision bein made to change the direction of motion 0% the harness cords from the horizontal planes to vertical planes, as is disclosed in my prior patent of which the presentvmechanism is an improvement. Mounted upon the cross pieces B of the loom frame A are, in the adaptation illustrated, a series of supporting frames 1 over which the harness cords pass, so that these harness cords will have vertically disposed portions lying over the warp threads. One of these frames only will be specifically described.

' The supporting means for the harness comprises a pair of clamping brackets 2 adjustably mounted upon the loom frame through the instrumentality of the clamping screws 3. The supporting frame comprises the U- shaped holder 4 pivotally connected to the clamping brackets 2 by means of the pivot bolts 5. The side membersof the holder 4 are channel shaped so as to slidingly receive the rectangular frame '6 carrying a plurality of spaced rods 7 of glass or the like, there being one of such rods for each horizontal row of grifi' bars E of the jacquard mechanism. It will thus-be seen that the harness cords of the lowermost row of grifi' bars, indicated by the reference character a, will pass over the lowermost rod 7, changing their direction from the horizontal to the vertical, such vertical portion depending to a point adjacent the warp threads. Each of these harness cords of the row is connected to its proper coupling cord and mail through which the warp thread passes. The next higher row of harness cords b of the horizontal row of grifi bars pass over the second rod 7 of the frame and depend in close proximity to the harness cords a of the first row mentioned. Without referring to the additional harness cords, the same arrangement applies to the various other series of harness cords 0, (1, etc. Within the frame 6 are mounted a series of vertical wires or spacing rods 8 held in their spaced relation by means of the apertured reeds or holding bars 9, there preferably being employed one of such bars at the top, one at the bottom, and one centrally of the frame, and these bars hold the harness cords of the respective rows separated orspaced' properly apart.

Referring to the mounting of the frame 6, it will be observed particularly by reference to Figure 2 of the drawings that the said sliding frame is held at adjusted position by means of the adjusting screws 10 carried by the bottom member of the holder 4: and by means of these screws the frame 6 may be raised or lowered in its holder'for the purposes hereinafter specifically pointed out.

drawings, consisting of theside bars 11 which are connected to the jacquard support D by=means of the fastening members 12. Each bar is sustained by the necessary intermediate supporting standards 13 carried by the loom frame. Upon such side bars are mounted at each side of a frame 1 a pair of clamps 14, adapted to engage with the frame and hold it in its fixed position It will be apparent from the foregoing that a wide range of adjustment of the harness is permitted by virtue of the arrangement hereinbefore described and now to be further set forth. In the first place, the support D for the grifi' bars is shiftably mounted upon the support C and held in any desired position by means of the clamping screws 16, and a stop screw 17 is secured to the loom frame at each side of the support D so as to hold this member at its fixed position. Obviously, movement of the support D toward the left will cause the harness cords to be raised and movement of this support D in the opposite direction will ef fect lowering of the harness cords, speaking with reference to the vertical portions of the cords in each instance. Furthermore, swinging of the frames 1 about their respective pivots 5 will likewise cause the harness cords to be raised or lowered, but more particularly this swinging adjustment of the frames is designed to control the position of the series of cords a withrespect to the next series I), and so forth, so that when it is desired to bring these series of cords into closer relation the frames 1 will be swung toward the jacquard, as when weaving narrow ware, while the swinging of the frame 1 in the opposite direction away from the jacquard will modify the position of the series of cords to increase the space between the same. The vertical adjustment or the sliding of the frame section 6 upwardly or downwardly will obviously lift or lower the harness cords, and these various adjustments are provided in order that the disposition of the harness cords' may be regulated both with respect to each other and with respect to the spaces in the batten H through which the warp threads pass. All of the cords in the row a are held in their regular spaced order, separate and distinct from the cords making up the series 7), and so forth, and the cords which depend from any one frame are capable of being adjusted as a unit by the movements or adjustment of that particular frame. All of the frames may be simultaneously adjusted by the bars 11.

Hence it follows that any framed roup of cords X may be adjusted with re ation to another framed group of cords X as may be desired, to accord with the spaces in the batten, or to accord with the width of the fabric which is woven. If the fabric is wide the frames 1 are adjusted closely together, Whereas if a plurality of fabrics are being Woven by the loom mechanism the frames 1 are separated into the position as shown in Figure 1. In order to maintain the harness cords in grou ed relation with respect to the individual fa rics, I preferably employ, in conjunction with the supporting frames 1, compass'boards 18 constructed as shown in Figure 5 of the drawings. These frames are composed of the longitudinally arranged rods 19, 19', and transversely arranged rods 20, each of which is removably mounted in its position to produce the proper index to accord with the weaving. The side member 21 of the compass board is formed with a flange 22 engaging about the I-beam J, whi e the opposite side member of the compass board, indicated 23, is provided with a clamping or set screw 24 engageable with the conti ous I-beam J for securing the compass l idard in its proper position. By employing the compass boards in this manner all the cords of a group X are maintained in close relation so as to fall directly vertically from this board to the warp threads, and said frames are individually adjustable as may be desired. The complicacy of interlacing of-harness cords is greatly simplified by such an arrangement, so much so that unskilled labor may be employed for the purpose of preparing the looms for operation, and the ,removability of the bars 19, 19, and 20 makes it possible to modify the index at will without dislqonnecting the harness cords from the ac s.

It will be observed in the drawings that the vertical sections of the harness cords are attached to the horizontal sections at points adjacent to the frames 1, and in reference thereto I desire it to be understood that this arrangement may be modified as desired. Other changes in the specific details of construction of the a paratus may be made without departing 0111 the spirit of the invention and within the scope of the claims hereto attached.
