JACQUARD Loom.

Specification of Letters Patent.

yatented June 25, 1907.

` Application iiled JulyZ', 1905. Serial No. 271,395.

To all whom t may concer-7c.-

Be it known that I, SAMUEL SMITH, a subject of the King of GreatBritain, residing at Toronto, Province of Ontario, Canada, have invented certain new and useful Im rovements in Jacquard Looms, of which `t 1e following is a speciiication.

My invention refers to im rovements in Jacquard power looms for t e weaving of Brussels and Wilton carpet rugs or squares, or for stair carpets of similar character, and is particularly but not exclusively applicable to looms for weaving carpets of widths equal to the ordinary or single width of twenty-seven inches. In power looms of this classwhich contain a card cylinder of usual construction and wherein a multiplicity of circles or chaplets of perforated attern cards are employed so arranged side y side as to have cards in the different circles simultaneously engage with said cylinder for the purpose of having needles contacting with said cards control the formation of the warp shed, it has been customary heretofore to provide four hangers, and to stretchcontinuous wires between said hangers upon which the portions of adjoining circles of pattern cards farthest removed from said cylinder would all be supported in a series of folds, and from which they would be withdrawn and conducted toward the cylinder as the latter was being revolved.

The objects of my invention are to provide suitable and improved means for supporting such circles of cards, and for arranging said supports to best advantage with reference to said circles and with reference to each other. I attain these objects by the use of appliances as illustrated in the accompanying drawings, wherein Figure 1 is a front view, partly in section, of such supporting means, the left-hand portion of said Fig. 1 showing the descending portion of a circle .of cards, and the middle `portion about one-half of the descending and one-half of an ascending portion of such a circle, while the right-hand portion illustrates the hangers and wires for the support of a third circle of cards. Fig. .2 is a ground plan of my improved appliances, the left-hand portion showing one of the card circles suspended thereon, while retaining wires are shown in the central portion and-only the hangers for receiving the wires are shown in the right-hand portion. Fig. 3 is an isometrical representation of a portion of a Jacquard loom provided with my improvements, portions of the structure and of the card circles appearing broken away and the main supporting frame of the loom, for purposes of clearness of the drawing, being omitted. Fig. 4 is a vertical cross section,` drawn to an enlarged scale, of my improved form of hanger for supporting the wires from which the card circles are suspended.

Corresponding figures of reference throughout the different views refer to corresponding parts.

In said drawings 10 represents the main frame of the loom having horizontal girders 11 and horizontal cross girders 12r all secured to the main frame.

13 is the card prism or cylinder. The usual means for causing intermittent revolving movement, and for thereby advancing the circles of cards, step by step, 0f the card cylinder are not shown in the drawings as theyy bear no direct relation to my invention.

15', 152 and 153 are three circles or chaplets of pattern cards 16 made of pasteboard and perforated and laced together at points as 17, 17, in usual manner and made to pass over and contact with cylinder 13.

18 and 184 are two crescent-shaped hangers attached to cross girders 12 and placed outside of and close to the outer edges of the outer pattern circles, while 182 is such a hanger placed between pattern circles 15 and 152 and 183 a corresponding hanger placed between pattern circles 152 and 153. All said hangers are shown to be of substantially crescent-shaped configurations and to comprise a vertical web 19 and an outer arcshaped body 20 of suflicient Width to form two fianges 21 and 22 extending laterally from said web so as to be capable of receiving and supporting the ends of wires 23 attached to the cards and from which the portion of a card circle farthest removed from the card cylinder is supported in folds, movements of the cards toward and from said cylinder taking place in the direction of the arrows, and while one after another of the folds is lifted with its respective supporting wire owing to the intermittent revolving movement of the card cylinder, the ends of said wires resting loosely upon flanges 21 and 22, respectively of said hangers. Hangers 18 and 184 may vbe constructed like hangers 182 and 183, the

outer iianges on the former hangers however not being required.

24, 24, are guide rollers or bars over which IOO the cards pass successively, said guides being continuous so as to make each serve in guiding all three card circles and thereby securing a uniform movement of the same.

25, 25, are connecting rods provided with suitable heads and screw nuts. Said rods pass through suitable eyes 26, 26 in the upper extremities of hangers 18, 182, 18J and 184 and serve to secure the latter to girders l2.

27 is a connecting rod passing through suitable corresponding perforations in webs 19 of the different hangers.

It Afrequently happens that in a pattern covering several ordinary widths and wherein borders running lengthwise are employed, it becomes desirable to substitute different borders for those previously employed, while continuing to use the same central body portion. Under the mode of supporting` a series of card circles from continuous wires heretofore employed such a change would require the entire removal of all such supporting wires and in consequence that of all three card circles from the loom frame, notwithstanding the fact that the central circle of cards would have to be put back again immediately into its original position at the same time that new outer card circles containing the patterns for the new border and for adjoining parts of the main body were being substituted. Of course, during such changes the loom remains idle and it will therefore readily be seen that under my improved arrangement a material saving of time and therefore an increased output will be secured, as the central card circle in my case remains undisturbed. However contingencies may arise where the outer card circles will remain undisturbed and a dierent central body portion only will have to be substituted, my improved system in general permitting of changes in any longitudinal portion of the carpet. Further, the diiierent circles of cards under my improved arrangement may be shifted longitudinally with reference to each other while leaving the majority of the wires undisturbed, and thereby new effects may be produced in the pattern without detaching either one of the circles of cards from the loom and in a much simpler and quicker way than under the present system of continuous wires supporting a multiplicity of card circles. Further as these card circles are very heavy and as they are apt to suffer much from repeated handlings, my improved arrangement will produce not only a saving of labor but also a very material saving as far as the cost of producing new pattern cards is concerned, and, as in order to be able to repeat a pattern at a later period it is important to provide for storing these rather bulky card circles, it will be seen that the saving in storage space due to my invention is an important and valuable feature. Besides, the strain on the supporting wires and danger of 85eme deliecting or breaking the same is reduced materially.

I do not wish to confine myself to the details and detail combinations herein set forth, as it will readily be seen that the same might be varied materially without departing from the spirit of my invention. Thus for each of the intermediate hangers 182 and 183 there might be substituted two independent hangers, so as to furnish for the support of each of the three circles of cards two independent hangers. Ilurther, in )lace of the crescent-shaped hanger described above any other suitable form of support or hanger might be employed. I do not wish to limit myself as to the number of card circles to be employed, as their number will be determined altogether by the width of the loom, or the width of the pattern to be produced.

It will of course be understood that where in a carpet or rug of the ordinary width of twenty-seven inches certain longitudinal portions, such for instance as the border portions, are to be changed the attern cards will be so divided longitudinal y as to make the outer portions contain the patterns for the borders, and the inner portion to contain the patterns for the body, the perforated parts of all three sections aggregating twenty-seven inches.

I claim:

l. In a Jacquard loom, the combination with the card cylinder, of a multiplicity of circles of pattern cards adjusted to simultaneously contact with said cylinder while the same is being actuated and means for detachably supporting one of said circles on its way to said cylinder independent of the supporting means in contact with an adjoining circle of cards.
