UNITED STATES PATENT JOSEPH HAMILTON, 'OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO JAMES DUNLAP CARPET COMPANY, OF PHILADELPHIA, PENNSYL- VANIA,` A CORPORATION OF PENNSYLVANIA.

YARN-PRINTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 699,948, dated May 13, 1902.

Application filed April 18. 1901 To all whom it may concern:

Be it known that LJosEPH HAMIL'roN,a citizen of the United States, residing at the city of Philadelphia, State of` Pennsylvania, have invented certain new and useful Improvements in Yarn-Printing' Machines, of which the following is a full,clear, and exact description, reference being had to the accompanying drawings,forming a part of this specificatiou.

This invention relatesto that class of yarnprinting -machines in which the yarn to be printed is wound upon an intermittently-rotatable drum and in which a color-containing box provided with a color-applying wheel and oppositely-disposed rubbing devices is carried back and forth beneath and parallel to the axis of the drum in-such manner that the said Wheel will apply longitudinal ridges or stripes of color to the opposing yarn and the rubbing devices will, at the end of each stroke of the color-box, be moved into and out of operative position relatively to the yarninV alternate succession, so as to act alternately` upon the successive ridges or stripes of color applied to the yarn.Y

My invention resides especially in a novel construction and organization of rubbing devices and of the controlling mechanism therefor Wherebya uniform and effective rubbing and distribution of the ridges or stripes of color upon the yarn are attained, as will behereinafter particularly described and claimed.

In the drawings, Figure 1 is an-elevation of a portion of a yarn-printing machine in which my invention is embodied. Fig. 2 is a longitudinal section through the trackway, showing the mechanism for controlling the active and idle positions of the rubbing devices. Fig. 3 is a transverse section as on the line x oc of Fig. 2. Fig. 4 is a sectional elevation of the color-box, its carriage, and the rubbing devices, showing a portion of the tra'ckway for saidcarriage and one end of the bar for controlling the positions of the rubbing devices. Fig. 5 `is a transverse vertical sectionl as on the lineV y y of Fig. 4.

ranged beneath and parallel-to theaxis of the drum; C, a carriage provided with wheels c., which bear upon the rails of the trackway, and c a band connectedatits extremities with the carriage and passed around pulleys c2 c3, driven b vsuitable mechanism to effect the traverse of the .carriage back and forthV on the trackway. Upon the carriage is de- 2 tachably supported the color-containing box D, which includes in itsconstruction a supply-wheel d, adapted .during the traverse of the carriage beneath the drumvto roll against the opposing yarn and apply ridges or stripes 0f color thereto.

The parts above mentioned require no de tailed description herein, as they are of wellknown construction and operation.

Supported in bearings at the respective ends of the carriage are vertically-movable posts 1, which are provided on their lower ends with lugs 2 and are maintained yieldingly depressed by the action of encircling springs 3, interposed between the respective lugs and the under side of the carriage. To each of the lugs ispivoted a depending slotted roller-bearing 4, equipped with an anti- ;friction-roller 5. The said pivotally-mounted ibearing 4 is maintained in vertical position jnormally by gravity. While freely movable toward the body of the carriage, the said pivoted bearing is prevented from swinging vrearward beyond the vertical by a suitably- :disposed stop 6 thereon'abutting against the 'opposing edge of the lug.

receive a telescopic or independently-movable stem 8, which is maintained normally raised by the action thereagainst of a spring 9, confined within the socket. A lateral pin 10 on the stem extends through a vertical slot 11 inthe post and prevents rotation of the stem. On the stem is formed or securedan L-shaped bracket 12, to the upwardly-projecting limb of which is pivotally connected an outwardly- The upper end of the post 1 is socketed toV Encircling this pin is a spring 16, which,

4 bearing against the arm and against a washer 17,"imposed on the bracket 12, tends to yieldingly maintain the link-arm 13 in a normal or raised position. The two oppositely-disposed links face outwardly on their respective bracket-supports. IIence the rounded surfaces of their arms 13 incline outwardly from the color-.box D, and they are arranged in such horizontal planular relation thereto that while their bearings are in longitudinal alinement with the color-wheel their upper surfaces are normally below the plane of the periphery of the color-wheel.

Between the rails and parallel therewith is supported a bar 18, which is movable vertically into and from the path traversed by the pivotally-supported rollers 5 during the reciprocation of the carriage.V The ends of the bar are preferably beveled, as indicated, to facilitate the passage thereon of said rollers. This bar is supported horizontally upon a series of upwardly-inclined arms 19, carried by rock-shafts 20, having their bearings in the rails of the trackway. The arms are preferably provided with antifriction-rollers 21 for the support of the bar. Depending from the ends of the rock-shafts are arms 20, which are united by means of links 22, so as to be movable as a unit. One of these latter arms is con nected with apart of the main frame by means of a strong retracting-spring 23, which -tends to turn the rock-shafts in a manner to maintain the arms 20 and, perforce, the bar 1S normally elevated. One of the arms 20 is also connected, by means of a link 24, with a treadle 25, whereby when the latter is depressed (by the foot of the operator) the respective arms will be moved against the action of the spring to elect the lowering of the bar 18.

From the foregoing it will be seen that the bar 18 is maintained normally raised and that during the movement of the carriage in either direction the depending pivotallymounted roller 5 of the forward orleading rubbing device will abut against and ride idly upon the bar. It will also be seen that the wheel of the traveling color-box will apply a ridge or stripe of color to that part of the yarn against which the wheel rolls' and that the roller 5 of the rearward rubbing device will bear against and along the opposing bar and be forcibly raised therebyin a manner to elevate against the compression of the spring 3 the post 1 and its appurtenances, including the link 13 14, causing the rounded arm 13 of the latter to bear against the yarn and rub along and distribute the ridge of stripe being applied by the color-wheel until the roller 5 escapes the bar at the end of the stroke of the carriage, whereupon described supporting actuating mechanisms of the rubbing device will resume their normal position. In view of the independent vertical movement of the stem 8, as well as the independent rocking movement of the spring-actuated link within its bracket-bearing 12, the rounded arm of said link will be caused to press yieldingly against and accommodate itself to any irregularities or variations in the strands of yarn, thus insuring a uniform and effective rubbing action. In the next succeeding strokeof the carriage the then leading rubber will be moved into action by its engagement with the opposing bar. Thus at the end of each stroke of the carriage the rubbing devices will be moved into and out ofoperation relatively to the yarn in alternate succession, so as to act alternately upon the successive ridges or stripes applied to the yarn by the rotating color-wheel.

If it be desired to apply the ridges or stripes 'of color without spreading or rubbing the same, the bar 18 is depressed by the operator preparatory to and during the stroke of the carriage, in which case the rubbing devices travel idly below the yarn on the drum.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a yarn-printing machine, the combination with the yarn-drum, the carriage, the color-box and its wheel, and the rubbing devices on the respective ends of the carriage, of a horizontally-disposed bar, upwardly-inclined arms supporting said bar, rock-shafts carrying said arms, other arms extending "downwardly from said rock-shafts, and links uniting said last-mentioned arms to cause them to operate as a unit; devices operating to maintain the horizontal bar normally elevated, and means to effect an opposite lowering movement of said bar when desired.

2. The combination with the yarn-drum, the carriage, the color-box and its wheel, ot' the rubbing devices at the respective ends of the carriage, said devices comprising each a verticallymovable support, a spring -controlled link pivotally mounted in an independent bearing at the upper end of said support, operating to maintain the same yieldingly in position, springs to maintain said supports in normal position, a roller, a slotted bearing therefor.pivotally mounted on the lower end of said support, a horizontallyarranged lifting-bar having an inclined end, with actuating means operated by a treadle to bring said bar into the path of said roller; substantially as described.

3. The combination with the yarn-drum, the carriage,the color-box and its wheel, of the rubbing devices at the respective ends of the carriage, said devices comprising each a vertically-movable post, means to maintain it in normal position, a stem independently movable on said post, a spring to maintain said stem normally raised, a spring controlled link pivot-ally mounted on said stem, together with means for bodily raising the said post with its connections, substantially as described.

4. The combination with a yarn-drum, the carriage, the color-box, the color-wheel, the rubbing devices on the opposite ends of said IOO IIO

carriage, means to yieldingly support each fixed my signature this 13th day of April, rubbing device in an independently-movable A. D. 1901. post, spring devices to maintain the said post in normal position, and means to raise said 5 post against counter spring action; substan- Witnesses:
