WALTER ERBEN, OF RADNOR, PENNSYLVANIA.
APPARATUS FOR EXAMINING YARN.
Specification of Letters Patent.
Patented July 18,1911.
Application filed February 29, 1908. Serial No. 418,561.
To all whom it may concern:
Be it known that I, IVALTER ERBEN, a citizen of the United States, and a resident of Radnor, Delaware count-y, Pennsylvania, have invented certain Improvements in Apparatus for Examining Yarn, of which the following is a specification.
One object of my invention is to construct an apparatus in which a number of ends of yarn are exposed to the view of the operator so that any defects in the yarn can be readily detected and such defects removed; and a further object is to arrange the examining board that the spools and other mechanism are out of view of the operator, so that the attention is concentrated solely upon the yarn as it passes before the operator.
My improved apparatus is so arranged that the yarn is taken from the creel-frame and travels over an examining board and is wound upon spools from which the yarn can be transferred to bobbins, other spools, or beams, or it can be made into hanks, or skeins, as desired.
In the accompanying drawings :Figure 1, is a side view illustrating my improved apparatus for examining yarn; Fig. 2, is a front view, showing the examining board; Fig. 3, is a rear view; and Fig. 4, is a perspective view of sufficient of the apparatus to illustrate my invention.
In the present instance the apparatus consists of two side frames A, A connected together by transverse tie rods. On the front of the apparatus and extending from one side frame to the other is an examining board B made in the present instance of sheet iron blackened, although the examining board may be made of wood or of other metals and suitably colored so as to be clearly distinguishable from the yarn. In the present instance the apparatus is used for examining white yarns and, therefore, the face of the examining board is made black.
C, C, C are three spools upon which the yarn is wound after it has passed over the examining board from the creel-frame W; these spools have spindles mounted in slots (Z in bearings D forming part of the side frames. Mounted in slots d are the spindles of the drums E upon which the spools rest and these drums are driven so as to impart motion to the spools C; the spools being forced into frictional contact With the drums by the pressure of the weights 0 resting upon bars 0 adapted to guideways in the slots cl.
F is the driving shaft on which are mounted fast and loose belt pulleys f and f, and on the shaft is a gear wheel f meshing with a gear wheel 9 on the shaft G and on this shaft is a sprocket wheel 9 and on each of the drums E are sprocket wheels 6.
h is a driving chain passing around the sprocket wheels 9 and e and also around the idler wheels a mounted on studs projecting from the frame A. These idler wheels are so arranged as to throw the driving chain out of line to increase the bearing of the chains upon the sprocket wheels 6.
e is an idler for taking up the slack on the lower run of the chain.
I is a treadle pivoted at i to the end frame A, this treadle is within easy reach of the inspector and is connected to one arm of a bell crank lever I by a link 2", which in turn is connected to a lever I by a rod 2' The lever I actuates the shifting rod 2' carrying the shifting arms 2", so that when the treadle is pushed down the belt is thrown on the fast pulley and the mechanism set in motion. As soon as the treadle is released the machine will stop, as the belt is thrown on to the loose pulley.
The yarn ac passes from the spools on the creel frame W in the present instance through eyes in the guide bar a, the eyes being staggered to accommodate a greater number of strands of yarn. The yarn then passes over a roller N situated directly above the examining board B, between spacing pins 6 and over the board, then between other spacing pins Z) and around a roller N directly under the examining board, and through eyes in the guide bars 8, 8, 8 The two upper strands preferably pass over guides at and in order to prevent any unevenness in the winding upon the spools 1 preferably reciprocate the guide bars 8, s in any suitable manner. In the present in stance I provide a lever M which is pivoted at m to a bracket on one side frame A and the lever is slotted at its upper end and on the guide bar 8 is a pin which enters this slot.
Mounted in bearings on the bracket A is a shaft m having a cam m which acts upon the lever M, tending to force it in one direction. A spring m on the pivot pin m tends to force the lever in the opposite direction, consequently a reciprocating motion is given to the bar 8. The shaft m is driven from the spindle of the central drum E by the worm and worm wheel a, 6. Instead of duplicating this device at each drum I preferably connect the other two guide bars to the central guide bar, as shown in the draw ings.
p is a rock shaft adapted to bearings p projecting from the side frames and on this rock shaft are three arms 72 having slotsand on the end of each guide bar a, s, s is clamped a plate having a pin which enters the slot in the arms 2 so that as the central guide bar is reciprocated the other will reciprocate with it.
One of the main features of my invention is to so arrange the examining board in relation to the spools upon which the yarn is to be wound, that the examining board will be situated between the operator and the spools, and the board is of such a length and width that when the operator is in front of the examining board nothing is visible except the yarn upon the board; therefore the entire attention of the operator is concen trated upon the yarn and defects in the yarn are readily detected, also the yarn can be arranged so close together that the least defeet can be readily seen and this defect quickly removed, in some cases Without stopping the mechanism while in other cases the mechanism can be brought to a standstill while the defect is taken from the yarn or the yarn broken to remove the defect and the ends again united.
The operation of the apparatus is as follows :The position of the operator is in front of the examining board and when the machine is set in motion, by placing the foot. upon the treadle, the belt will be shifted onto the fast pulley and the spools c, c, 0 will slowly revolve drawing the yarn from the spools on the creel-frame W over the examining board B, and as the face of this of the yarn. In some instances the defects in the yarn can be picked oft without stopping the travel of the yarn, but when it is desired to break the yarn in order to remove the defect then the machine is stopped, the repair made and the machine quickly set in motion again. By this means a great quantity of yarn can be examined and the defects removed so that when the yarn is delivered it is in a perfect condition.
1. The combination, in apparatus for examining yarn, of a creel frame, a series of winding-off spools, an examining board in front of and binding said spools, means for directing a series of independent strands of yarn from said spools across the surface of the board, said strands being spaced apart. and one or more spools behind said board upon which the yarn is wound after passing the same, all of said spools being mounted independently of the board and the latter being of such a size as to hide all of the spools from the view of the operator located in front of the board so that the operators attention will be directed to the individual moving strands of yarn.
2. The combination, in an apparatus for examining yarn, of a solid examining hoard disposed at an angle with respect to the vertical and having a surface of a contrasting color from the yarn, a creel frame hack of the examining board, a series of spools mounted on said frame, guides for directing independent strands of yarn from the creel frame to the board and from the latter to the spools, the board being of such size as to hide all of the spools from the view of the operator located in front of the board, and rotating means disposed adjacent the upper and lower edges of the board over which the threads undergoing examination must pass.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
VALTER ERBEN.
