2 Claims.

The invention relates to improvements in weaving machines for weaving wire mesh fabric and has reference more particularly to novel mechanism for winding the woven fabric on to a drum and. for measuring the quantity so wound.

Looms for weaving wire fabric are provided with a hand drive which when actuated will produce movement of the fabric in the direction of feeding or in a rearward direction. The drive.

10 is used to properly adjust the position of the woven fabric with respect to the oscillating shuttle bars and beater frame before starting the machine, and quite often the -adjustment resultsrin movement of the fabric backwards which tends to unwind the woven material from the drum or roll on to which the same is wound. As it is necessary for most ecient operation of the weaving machine that the material be held under tension excessive unwinding of the same is to be avoided. An object of the invention is to provide appar-atus for winding wire mesh fabric onto adrum and k for measuring thepquantity so wound as the operation proceeds, and which will bel driven from the weaving machine in a manner to permit adjustment without developing excessive slack in the woven material.

With these and various other objects in view, the invention may consist of certain novel featuresv of construction and operation, as will be more fully described and particularly out in the specification, drawings and claims appended hereto.

In the drawings which illustr-ate an embodiment of the device and wherein like reference characters are used to designate like parts- Figure 1 is an elevational view showing the winding and measuring mechanism of the invention in association with a conventional weaving machine;

Figure 2 isa front elevational view of the windl ing and measuring mechanism;

Figure 3 is a top plan view of the same;

Figure 4 is a side elevational View of the mechanism; and

Figure 5 is a sectional View showing the ratchet connection provided in the drive to the winding mechanism.

The longitudinal wires I0 forming the Warp strands of the fabric are fed in any suitable manner to a weaving machine of conventional design, indicated by I2, which is not shown complete as the same forms no part of the present invention. The Warp strands are interwoven by the machine in the customary manner with weft pointed strands to form wire mesh fabric I4 which is passed under the machine and wound onto? a drum by mechanism to be presently described. Frequent interruptions in the operation-of the machine occur as the wires may break andthe chine and having gear I6 xedly secured toits ,1 5 end for meshing'with gear I1 secured to shaft I8 vertically positioned and journalled in bearings I9. The shaft carries a worm gear 20 mesh' ing with gear 2I for rotating the friction rolls 22 which feed the longitudinal wires to the'machine. Gear 23, also i'lxed to shaft I8, operates through a plur-ality of gears to drive a spur v'gear 24,'which in turn meshes with lgear 25r xedly secured to sh-aftfZG. Said shaft is thus driven from the hand drive I5, but at a considerably reduced speed.

4The winding mechanismof the present invention is driven from the weaving machine through connection with shaft 26 and in order to prevent reverse rotation of the winding mechanism when the hand drive is rotated in a direction to feed the fabric backward through the weaving machine the invention provides ratchet mechanism between shafts 26 and 21. The same consists, as shown in Figure 5, of a hub member 28 having a pawl 3B and a ratchet wheel 3l associated therewith and which is fixed so as to rot-ate with shaft 21. It will be seen from the above that shaft 2l has rotation in one direction only, that is, to cause winding of the inaterial. Gears 32 operatively connect shaft 21 and the transverse shaft 33 (Figures 2 and 3) which carries at its opposite end a pulley 34. This latter shaft is journalled in the supporting frame structure 35 having uprights 36 and rotatably mounts a roller 3l for contact with the woven fabric. The uprights 36 journal shaft 38 carrying drum Ml onto which the material is wound to form a roll of the same. When the roll reaches the required size the shaft 38 can be released by actuation of lever 4I to permit removal of the drum 4B from the apparatus. Another shaft and drum of similar construction can be journalled in the uprights and the operation again resumed or the roll of material can be immediately removed from the drum and the same replaced. Y

One end of shaft 38 has connection with pulley 42 which is driven from pulley 34 by the belt Y 43 held under proper tension by the idler roller 44. The belt provides a friction drive for the drum 40 Which is driven from; shaft 21 through the instrumentalities .describedW Provision is thus made for a considerable slippage between the driving shaft and drum, which is necessary since the quantity of material wound on the E Qdr'um per revolution increases as the diameter 'of the roll becomes larger, Whereas, the quantity K of Woven material supplied by the machine is V fairly constant. By the structure described the material iswound on the drum and considerable tensionis placed on the same vto also maintain the Woven fabric in the weaving machine under tension. As it may be necessary at times to vary the tension on this fabric the'amountof slippage occurring in the frictiondrive ismade adjustable within limits through the provision of the idlerV roller 44 yieldingly held by coil spring 45 in contact with the belt 43 which thus holds the same taut. Y

The uprights 35 journal shaft 46 which carries spaced arms 41 supporting a roller 48 havl ing a knurled periphery and of considerable weight. The roller normally rests on thel roll of material wound on the drum 40 andY serves to maintain the surface of the -roll flat and free of kinks and wrinkles. The roll forms part of the counting mechanism as the same has rotation with the roll of material and which rc-` tation vis in proportion tothe quantity of material wound on the drum. A counter is operatively connected through chains 5| with the be limited bythe exact embodiment of the d vice shown, which is merely by way of illustration and not limitation, as various and other forms rof the device will of course be apparent to those skilled in the art Without departing from the spirit of the invention or the scope of the claims. I claim: 1. Thecombination with a weaving machine of means located to the rear of said machine for releasably and rotatably supporting a drum,V said .drum receiving the Woven material which is wound on the drum to form a roll of material, connections operatively connecting the weaving machine With the drum including a friction drive to permit slippage of the drum with respect to the machine, a roller havin'gcontact with the surface of the roll of material on the drum .to maintain the same flat,Y means pivotally supporting the roller to permit bodily movement of the same whereby the roller can be lifted out of contact with said roll-of material, a measuring instrument,` and connections from saidv permit bodilymovement of the roller, said roller. having contact with the roll of vmaterial on the drum to maintain the Vsame ilatv and freev of kinks and wrinkles, a measuring instrument and roller, whereby. said connections from' said instrument to said roller drives the measuring instrument in proportion to the quantity of material wound on the drum.
