YARN-PRINTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 595,984, dated December 21, 1897.

Application filed May 24,1897. Serial No. 637,822. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM J. WEBB, a citizen of the United States, residing at Yonkers, county of VVe-stchester, and State of New 5 York, have invented certain new and useful Improvements in Yarn Printing Machines,

fully described and represented in the following specification and the accompanying drawings, forming a part of the same. This invention relates to improvements in yarn-printin g apparatus of that class in which the printing mechanism proper,consisting of a color-box for containing coloring material and a distributing-wheel rotating therein, is removably mounted in a carriage adapted to reciprocate from end to end of a drum carrying the yarn and which carriage is provided with rubbing appliances movable automatically into and out of operative position alternately at opposite ends of the movement of the carriage for engaging the yarn and removing therefrom ridges formed between two or more adjoining stripes of the same color applied thereto by the wheel.

The present invention relates more particularly to such rubbing appliances and to means for automatically moving them into and out of operative position at the ends'of the movement of the carriage in opposite directions and to means for retaining the rubbing appliances during movement of the carriage in printing in the positions to which they are thus moved.

It also relates to means for automatically depressing slightly the operative rubber as it nears the drum, so as to avoid liability of contact between it and the edge of the drum or the edge of the row of yarn wound thereon and consequent injury to the rubber or injury and disarrangement of the yarn upon the drum.

In the accompanying drawings, Figure 1 is a side elevation of a yarn-printing apparatus embodying the present invention. Fig. 2 is a plan view of the same. Fig. 3 is an end View, partly in section, looking toward the right of Figs. 1 and 2. Fig. 4 is a similar view looking toward the left of said figures. Fig. 5 is a side elevation on a slightly-enlarged scale, illustrating both of the rubbing devices in inoperative positions; and Fig 6 is inwardly-curved brackets 26.

a detail on the same scale of one of the rubbing devices, illustrating particularly the means for depressing it as it nears the yarndrum.

. Referring to said drawings, the frame of the machine therein shown is provided with rails 2 3 for support-ing a Wheeled carriage 4, provided with cables 5 6, passing over pulleys 7 8, connecting with a suitable source of power for moving the carriage back and forth beneath the yarn-drum 9 in the usual Way. Hinged at 10 in the carriage 4 is a plate 11, provided with an opening 12, which registers with a similar opening beneath it in. the carriage 4 for receiving the removable color-box 13, containing the coloring material. On opposite sides of the opening 12 the plate 11 is also provided with bearings 14 15 for the shaft lb of a distributing-wheel17, immersed in the coloring material in the color-box 13 and which during the movement of the carriage engaging the yarn upon the drum 9 applies stripes of colors thereto in the usual manner. The plate 11 is also provided with the usual pulley 18, clutched to shaft 16 and connected by belt 19 with a second pulley 20 on one of the axles of the carriage 4 for the purpose of turning the distributing-wheel 17 in the color-box as the carriage moves under the drum, so as to insure a supply thereon of coloring material.

The contact of the distributing-wheel 17 with the yarn-d rum 9 is rendered yielding by the provision of a spring 21, secured to the carriage and engaging the under side of the plate 11, upward movement of the plate, color-box, and distributingwheel by the spring 21 being limited by a nut 22 on the upper end of a bolt 23, secured to the car- ,riage 4 and projecting through an opening in the free end of plate 11.

Pivoted centrally in brackets 24, secured to opposite sides of the carriage 4, is a rocking frame 25, provided at opposite ends with Between the brackets 2d at one end of the frame 25 is pivoted the curved bifurcated arm 27 of a rubber 28, while to the brackets 26 at the other end is similarly pivoted a rubber 29. Each of said rubbers is supported from the frame 25, so as to permit it to yield when in contact with the yarn upon the drum 9, by a spring between the arm 27 and a bracket 31 upon the frame 25 and which encircles a pin 32, secured to said bracket and passing through an opening in the arm 27.

As is well understood, rubbers such as de scribed are used only on the application to the yarn of the second and succeeding stripes of a series of adjoining stripes of the same color, and it is important that during the application of certain stripes, depending somewhat upon the width of the rubbers em ployed and their position relatively to the distributing-wheel-as, for instance, during the application of the first stripe of a series and during the application of isolated stripes-both of the rubbers should be out of operative position, as in such case if either of the rubbers should contact with the yarn the color of one stripe would be forced thereby into the adjoining and ditferently-colored stripe, thus blurring the pattern. In the present case, therefore, the rocking frame during the application of the first stripe of a series of the same color and during the application of isolated stripes to the yarn will occupy a horizontal position, as shown in Fig. 5, in which position both of the rubbers are out of operative position. The rocking frame 25 is also capable of assuming an inclined position, as shown in Fig. l, in either direction, in which position one or the other of the rubbersnamely, that which follows the distributing-wheeL-will be in operative position. The rocking frame 25, with its rubbers, is retained in its horizontal position by a spring 33, centrally secured to the carriage 4 and engaging the under side of the frame on opposite sides of its pivotal connection to the carriage.

The frame 25 is adapted to be rocked from its horizontal position to one or the other of its inclined positions, so as to render one of the rubbers 28 or 29 operative, and also to be rocked from one inclined position to another to reverse the rubbers at opposite ends of the movement of the carriage by mechanism which will now be described. For this purpose the frame 25 is provided with a lever 34, fulorumed at and one end of which is provided with a cam-slot 36, embracing a pin 37in the rocking frame, and the other or free end of which is provided with a laterallyprojecting bowl 38, which is adapted to be engaged so as to trip the lever 34 by cams 3f) 40 at opposite ends of the movement of the carriage. cam 39 at the end of the movement of the carriage toward the left, Fig. 1, the free end of the lever 34 is moved upwardly and its slotted end moved downwardly, as shown in Fig. 1, thus tilting the frame 25 and elevating the rubber 28 to operative position and cone spondingly lowering the rubber 29, while when the bowl 338 is engaged by the cam 40 at the end of the movement of the carriage in the opposite direction the free end of lever As the bowl 38 is engaged by the 34 is lowered and the frame 25 rocked in the reverse direction, the rubber 20 being thus elevated and the rubber 2S depressed. These movements of the rocking frame 25 take place whether at the time of the engagement of the bowl 38 with the cams 39 40 the frame 35 be in horizontal position and the rubbers both inoperative or be in one of its inclined positions with one of the rubbers operative. The form of the slot 36 and its position relatively to the pivot of the lever 34, as will be ob served, are such that the frame 25 will not only be rocked thereby into its inclined p0- sitions, but locked in that position, so as to retain the rubbers during the movement of the carriage in printing in the positions to which they have previously been moved thereby.

Mechanism is also provided in the present case for automatically restoring the frame from either of its inclined positions to horizontal position when desiredas, for instance, when the first or last stripe of a series of adjoining stripes of the same color or isolated stripes are to be applied to the yarn-so that neither of the rubbers will contact therewith and thus mar the pattern. The means for this purpose consists of cams 41' 42 at opposite ends of the movement of the carriage and each of which is adapted to engage the bowl 38 and trip the lever 34, so as to disengage the pin 37 from the end of the slot 30 an-d thus unlock the frame 25 from the lever. When the frame has thus been unlocked, the small further movement of the lever, aided by the spring 33, will move it from its inclined position to its horizontal position, in which both of its rubbers will ,be inoperative and will retain the frame and its rubbers in such position during the subsequent movement of the carriage in printing the first one or first two, if desired, of a series of adjoining stripes of the same color or in printing isolated stripes.

The cams 39 40 are, as will be observed, located slightly in advance of the cams 41 42, so that when in position themselves for tripping the lever 34 they prevent operative engagement therewith of the cams 41 42. In order, therefore, that the cams 41 42 may be rendered operative, the cams 39 40 are movably mounted in the frame of the machine, so as to be adjustable to and from operative position at the will of the operator. For this purpose the arm of each of the cams 39 40 is hinged to the frame of the machine and provided with a pin 43, engaging a slot 44 in arms 45, secured to a rock-shaft 46, mounted in suitable standards 47 and provided with an arm 48, connected by a link 49 to one end of a bell-crank lever 50, pivoted in a standard 51, and the opposite end of which is provided with a pin 52, entering a slot in a treadle 53, pivoted in a standard 54. On depressing the treadle 53 the cams 39 40 will be moved from operative position, shown by full lines, into inoperative position, shown by dotted bers rendered inoperative. the treadle, which remains depressed until lines, Figs. 3 and 4, and when so moved will permit the bowl 38 to pass without engagement. The bowl 38 will then be engaged by one or the other of the cams 41 42 and the frame 25 unlocked from the carriage and then moved by the lever and its spring 33 to a horizontal or inactive position and both the rub- On the release of the printing of successive adjoining stripes of the same color is resumed and the first or second stripe of the series has been printed, the cams 39 40 will be restored automatically to operative position to tilt the frame 25 by a spring 55, secured to the rock-shaft 46 and to a stationary part of the machine.

As the rubber following the distributingwheel in position to operate upon the yarn is sometimes liable to come in contact with the edge of the yarn-drum and thus be injured or to come in contact sidewise with the edge of the row of yarn upon the drum and thus injure or disturb it it is desirable that means should be provided for slightly depressing the rubber as it nears thedrum and retaining it in that position until it is beneath the drum, so that the rubber will move vertically into contact with the yarn when beneath it. Means are provided in this case for this purpose also, consisting of cams 56 57, secured to the rails 2 3 at opposite ends of the drum 9 and-which are adapted to engage bowls 58 on the lower ends of rods 59, secured to the arms 27 of rubbers 28 29,-respeetively, and passing through guides 60 in the ends of the rocking frame 25. Each of the cams 56 57 is of such length and so positioned relatively to the drum that as the rubber following the distributing-wheel in operative position nears the drum it will engage the bowl 58 corresponding to that rubber and depress the rubber against the pressure of its spring 30 and retain it in depressed position until it is directly under the drum, when the bowl 58 will become disengaged from the cam and the rubber be raised by its spring 30 into contact with the face of the yarn upon the drum. When the rocking frame 25 is in horizontal position, both bowls 58 will be lowered to such an extent as to clear the cams 56 57.

The rubbers 28 29 are preferably double the width of the distributing-wheel and mounted directly in line therewith, as shown, so that when operating they will embrace the ridges at both sides of the strips of yarn then being printed and overlap upon the unprinted and previously-printed yarn on the opposite sides of said strips. The width and arrangement of the rubbers, however, forms no part of the present invention, which may be used with rubbers of any desired width and position; but this feature is included in another application now pending in the Patent Office, in which I have fully described and claimed rubbers of such width and so positioned relatively to the distributing-wheel as to act upon the stripe being printed and the adjoining unprinted portion of the yarn and preferably of the width and positioned as shown,

and the method carried out by such rubbers.
