COUNTING MECHANISM.

SPEOIFICATION forming part of Letters Patent No. 663,924, dated December 18, 1900.

Application filed March 3 0, l 9 00.

T0 ctZZ whom, it may concern:

Be it known that LMAx J ULIUs NORDMANN, a citizen of the Kingdom of Saxony, residing at Dresden, in the Kingdom of Saxony, German Empire, have invented certain new and useful Improvements in Counting Mechanisms; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The object of my invention is to provide a mechanism for counting the number of yarns or threads in a reel and for regulatingthe size of hanks or skeins.

My invention comprises a number of revolving counting disks, rings, plates, or the like, each of which is adapted to count and limit the duration or number of working operations, and a regulating or adjusting mechanism placed parallel to the axis of the counting-disks.

In the accompanying drawings, Figure 1 is a part-sectional front view of the device as used in connection with yarn-reels for counting the number of threads or turns suitable for a skein or hank or for dividing the threads into certain quantities for different thick- Fig. 2 is also a front view, but with some of the parts in a different position to that of Fig. 1. Fig. 3 is an end view of the same. Yarns are frequently required in bundles of an unequal number of threads, while in bundles of like thread the first and last turn of the thread in a skein is separated from its group to facilitate the knotting with the hankbinding threads, and this varying distribution is effected by the device of the invention.

ais a portion of a reel-frame; b, a shaft fixed therein; 0 d, worm-wheel and worm, the latter set in motion from the reel-motor and slowly driving through the worm wheel a sleeve 6 and disk f, both in one piece and in rigid connection with the worm-wheel.- Upon the sleeve e, which is screw-threaded at its outer end, are arranged revolving countingdisks 9 to g, adapted to be fixed on the sleeve e and against the disk f by a nut g and washer- Serial No. 10,829. (No model.)

disk f after the recesses 72 of every two disks have been relatively adjusted.

t is a guide-bar fixed in the frame a, and having arranged on it a slide-block Z, under pressure at one side of a spring 7c and mow able to and fro with a rod on and thread-guide eyes n. The slide-block lis held by a pawlp, under the pressure of a spring 0, against the circumference of each counting-disk until the recess 71 of the same comes underneath the spring-pawl p, which then by the action of the spring 7; springs through said recess and bears against the next disk, to be held there until the recess h of this second disk comes underneath it and is passed through by it to the next disk, and so on. When the pawl has in this way passed by all the counting-disks g to g, it is finally pressed against the disconnecting-rod q, Fig. 2, which being then slid back against the resistance of the weaker spring 1'- disconnects the motor from the reel and causes this to stop, thus finishing the winding of skeins or thread groups upon it.v The slide-block l is then, with the spring-pawl 19, adjusted by hand upon the counting-disk g, Fig. 1, to lay a fresh skein upon the reel.

Each counting-disk is provided on its circumference with a scale, so that the number of threads or turns of each skein can easily be adjusted by turning the corresponding counting-disk with its recess in the proper position. The counting-disks are so arranged that for each revolution of the reel they are turned a portion of a revolution. Each disk, therefore, will count the threads or turns in a skein corresponding to its adjustment and according to the number of scale divisions on its circumference which lie between the commencing-point and the recess of the first disk and between this and the recess of the next counting-disk, and consequently all the disks will, while the regulating mechanism, with the thread-guide eye 02, springs the distance of one regulating-surface of the disks to another, lay a skein upon the reel each composed of the desired number or turns of thread. As, further, the circumference of the reel is constant or easily calculated, so also can be the length of thread or yarn for a hank or skein.

Instead of releasing the pawl 19 by means of recesses or openings on the circumference of the counting-disks the same end may be attained by means of teeth or projections arranged on the circumference of said disks or on rings or plates or the like, with the aid of a stop arrangement which would permit a forward movement of the rod on and of the regulating mechanism.

In a manner similar to that above described the device might be employed for many other purposes-for instance, the transmission of electric current or the delivery of liquids and grainy materials, the thread-guide eyes then being replaced by a contact-field or outletaperture orshut-off slide, as the case might be.

What I claim, and desire to secure by Letters Patent, is

1. In acounting mechanism, the reel-frame, a supporting-rod extending therefrom,a wheel placed upon the said rod and means for driving said wheel, combined with a revolving sleeve placed upon the rod, a series of counting-disks clamped upon the said sleeve and caused to revolve therewith, each of the disks having a notch formed through its outer edge, and which notches are adjusted in relation to each other, a rod also secured to the frame, a spring-actuated sliding block placed thereon and provided with a pawl which engages with the counting-disks, and a rod connected to the said block carrying guide-eyes, substantially as shown.

2. The reel-fra me, a supporting-rod extending from the end thereof, a spring-actuated sliding block placed upon the rod, a springactuated pawl connected to the block, and a rod also secured to the block and provided with guide-eyes, combined with a revolving sleeve mounted upon the frame, a mechanism for causing said counters to revolve, and a number of counting-disks clamped upon the sleeve, and each one provided with a notch or opening through its edge, and through which the pawl upon the block is adapted to pass as the block is forced inwardly by its spring toward the frame, substantially as described.

3. In a counting mechanism, a series of revolving counting disks and means for causing them to revolve, each of the disks being provided with a notch in its periphery, combined with a sliding spring-actuated block, a springactuated pawl connected to said block, and a rod connected to the block and provided with guide-eyes, substantially as set forth.

4. In a counting mechanism, the reel-frame, a series of revolving counting-disks mounted on the end of said reel-frame, and a mechanism for causing them to revolve, combined with a spring-actuated pawl, and a sliding rod actuated when the pawl has passed through all of the counting-disks, substantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.

MAX JULIUS NORDMANN.
