This invention relates/to an improved warplng frame.

In the warping frames at present ,in' use,

by the disposition of their component parts, the number of threads of each hank of warp formed is extremely limited, amounting at the very most to 400 as the practicable maximum, so that in the case of fine threads,-of silk, for example, it is necessary to prepare 1 a'great number of hanks for each warp beam. For this reason the operation in question is always slow and expensive, since if it is attempted to increase the number of spools, the framein which they are carried becomes extremely cumbersome and of little practical use. Serious difiiculties also arise in the passage of the threads and the formation of the double cross at each hank obtained. I

Furthermore, the varying frames of the kind referred to have the disadvantage that arises from the arrangementof the spools in the respective frames which results always I in the greatest difficulty in knotting broken threads when such are not in the first series and therefore within reach of the hand of the operator.. V

In the warping frame .of'the present invention the formation of the whole ofthe warp can be effected at one time of any width, even when threads of silk have to be dealt with, in which case they have to bevery great in number amounting to 20,000 or more. In addition to the advantages. which this Warping frame presents, is the advantage that all the spools of thread. are within reach of the hand of the operator in such a way knottingthe broken threads can .be carried out in a simple and convenient manner, and

therefore with a great economy of time.

The Warping frame herein referred to is hereinafter described with .referenceto the accompanying drawings infwhich the combin ation of elements composing; it are represented diagrammatically by wayof example. In Figure l is shown in plan the whole of the improved warping frame.

. F igures12 and 3 showrespectively in plan 50 and in "elevation the arrangementwofthe threads-from the spools in which they are I wound on to the winding drum of the hank formed.

Figure 4 shows-in elevation the arrangement of guides for the threads leading from the frame which carries thespools. I

Figure 5 is a detail of the frame which carries the spools just referred to.

Figures 6 to 12 inclusive are detail of'one form of thread guide shown in Figure" 4, in different phases of use and Figures 13 to 16 are modifications of the saidthread guide. I

. The warping frame described comprises: a frameA for carrying thespools, amovable thread guiding device B, a comb or reed with vertical teeth C and a winding drum D for the hank which is formed. v

The reed C and the drum D are those com monly employed in the present warping frames, so that there will be no object in specially mentioningthem in this description nor showing them in the accompanying drawm s. 1

' Theframe A which carries the spools consists'of a horizontal platform 1, mounted on wheels and adapted to move along the guides 2 arranged parallel to the shaft of thewihding drumD. Mounted upon the platform are two vertical spool-carrying members 3 and 4,

arranged to converge towards the said drum Dandcarrying on both sides thereof rows of spindles 5, for supporting the spools 6. The separation of the said members 3 and 4 may be as desired, but it is preferableto adopt that which is most convenient so that the operformed. At-the front part of each ofthe members guide may beof any type ofconstruction but in the example illustrated in the drawings it eration ofchanging the spools can be freely that the operations of substituting them and p is formed by a series of teeth or spikes-8 (see v Figure 5) (as many as there are spools plus one, including the respective -row) duly spaced apart and fixed to a plate 7" which in turn is fixed to the said member at itsedge. Asthe arrangement ofuspools is symmetrical on both sides of'each member-thethread guide mentioned may be double as is shown in the drawings, which facilitates its construction and erection. In orderto prevent the threads from disengagement with the thread employed therefor may vary.

The thread guiding device B consists of a frame 10 arranged vertically and carried by a support 11 of an system of construction and movablein any direction. In the frame 10 aremounted rods or bars 12, arranged vertically or inclined as shown in the drawings.

In order to permit the use-of bars of definite lengths the top cross bar 10 of the frame is adjustable in position and both the top cross bar and the lower one 10 are provided with a series of holes for the fixation of the rods or bars 12.

The bars 12 may be of various patterns and in the case illustrated in Figures 6 to 12 they are of rectangular section and provided at their centres and longitudinally with holes 13 suitably spaced apart and between every two holes a transverse groove 14 is formed. On the face of the bars 12 which face the drum 1), hinge devices 17 are provided at their ends and at convenient intermediate positions. The hinged devices 17 which extend the whole length ofthe bars are arranged in such a way that when they are drawn back towards the centre of the bar (see Figure there is left between them a space which is practically equal to the diameter of the holes 13, and when they occupy the contrary position they leave the transverse grooves 14 completely uncovered.

In the modification ofthe bars 12 shown in Figures 13 and 14, they are formed as a series of smallplates 18 provided with central holes 18 mounted between parallel bars 19, and spaced apart so that there pass between every two of them, other strips 20 similar to the first, with a hole 20 at its centre and mounted in their turn on the bar 21. The separation between these two bars 21 is less than thatof the bars 19 and in this form, by means of the arrangement of guiding elements of a suitable kind, a lateral movement of the strips 18 v over their entire length for. the passage of thethreads and in like manner the movable strips 20 are also constructed and supported on bars 21 This construction has theadvantage that it permits of the rapid formation of lines of holes 18 320 of more or P less inclination according to the particular requirements in each case.

Finally in Figure 16 is shown another mod- I ification of the bar 12 which is constituted by a comb or reed in which the small plates '22 are suitably separated from each other.

Furthermore, every two of the said, small plates are connected by members 23 forming a central passage 24. This systemofconstruction of the bars 12 is similar to the general case described and requires; the use-.of'spindles 15 and 16.

x The preparation of the warping frame the warps described is effected'as follows The spools 6 having been placed in the frame A and the bars 12 with the spindles 15 and 16 as shown in Figures 6, 9 and 10, the threads are passed from the spools in each horizontal row through the thread guide 7 corresponding thereto.,. For, the sake of greater clearness in this description four bars 12 will be used one for each of the faces of the two members 3 and 4 of the frame which carries the spools. The threads on leaving 7 proceed to the respective bar 12, the preced convergetowards the comb or reed G through which they, pass in a horizontal line. In the said comb or reed the preceding threads rejoin from all the bars 12 with which they unite to form the hank E which passes on to the winding drum D. V

For the method of formation of the double cross ineach hankof warp is as follows: As already statedthe threads in each bar 12 pass through the holes 13 and through the central part'of the openings 14 to enter between the spindles 15 and 16 (see Figures 6, 9 and 10). In this form the position of oneof the spindles, 15 changes for example, and the whole of the arrangement B moves towards the right (in relation to the drawings) with the result that the threads which pass through the grooves 14 are applied against the extreme left of the corresponding grooves, but those which pass through the holes 13 are made to move in the same way, an opening having been formed through 13 (see Figures 7 and 11)- through which the spindle passes. Accordingly the spindle 15 is dlsposed again in the original position and the spindle 16 drawsback to the edge of j' the bar and proceeds in the same mannerv as before whereby an opening14- =(see Figure l 1 8 and 12) is produced thus forming the double cross required.

It will be understood that with the warping frame herein described it is possible without any inconvenience to prepare warps of any width in one operation, that is to say apart from the formation of the hanks and the making up thereof it is suflicient that the comb or reed C be of the necessary amplitude in proportion to the convenient number of spools and the adequate number of bars 12 all of which can be accommodated in a very much reduced space. Y

The details of construction of the warping frame may be varied widely as may also its complementary elements.

Havlng now particularly described and I ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what We claim 1s:-

1. In a device of the character described, a thread guiding frame comprising a support, a plurality of bars carried by said support and having alternately disposed holes and slots formed throughout said bars, said holes and slots receiving and guiding the threads, and means associated with said bars for varying the respective positions of the threads re- }caeived through the holes and slots of said ars.

2. In a device of the character described, a thread guiding frame comprising a support, a plurality of bars carried by said support and having alternately disposed holes and slots adapted to receive and guide the threads, and rods pivoted upon one face of said bars and movable to vary the relative positions of the threads received through the holes and slots of said bars.

3. In a device of the character described, a thread guiding frame comprising a support, a plurality of bars carried by said 'support and having alternately disposed circular holes and transverse slots formed substantially throughout the length of said bars, said holes and slots receiving and guiding the threads, and a pair of rods hinged oppositely to each other upon one face of the bars and movable to vary the respective positions of the threads received through the holes and slots of said bar, the relative positioning of said rods upon the bars being such that when in one of their positions, the space between them will be substantially equal to the diameter of the circular holes in the bars, and when in their opposite positions, the space between them will be substantially equal to the length of the transverse slots in said bars.

In witness whereof we have hereunto set our hands.
