Specification of Letters Patent.

Patented Oct. 2'7, 1908.

Application filed March 23, 1908. Serial No. 422,809.

To all whom it may concern:

Be it known that I, GRANT Sirr, a citizen of the United States, residing in Paterson, Passaic county, NewJersey, have invented a certain new and useful Improvement in Measuring Apparatus for NindingMachines; and I do hereby 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 letters of reference marked thereon, which form a part of this specification.

My invention relates to machines for reeling or winding silk and the like and it has reference particularly to mechanism employed in such machines, and known commonly as clocks, for measuring the amount of ma terial wound on the reel.

My principal object is to provide a measuring mechanism which shall accurately per form its work, although the machine may run at a high rate of speed and thus make it necessary to take into consideration that the momentum of the parts which directly operate the clock under the influence of the thread being wound tends to keep the clock operating, or registering, after the need therefor has ceased, as when a thread breaks.

A further object of the invention is to provide means whereby the automatic clockstopping mechanism which I employ may be controlled in such manner in the starting and sto ping of the machine that it will be practica ly ineffective at these times, when the tension is not sufiiciently constant, and will therefore not act as an undesirable check on the clock operating parts which the lead to the breaking of the threads because of sudden resistance to the pull of the reel.

A still further object of the invention is to provide a winding or reeling machine with a simple, convenient and effective means'for controlling its operation in general.

My invention will be found fully illustrated in the accompanying drawings, wherein, Figure 1 is a front view of the improved machine; Fig. 2 is a view in side elevation thereof; Fig. 3 is a transverse sectional view taken just to the left of one of the clocks and showing certain parts of the clock also in section; Fig. 4 is a view of what is shown in Fig. 3 looking in the direction of the arrow in the reel :said figure, certain parts being omitted and others broken away; Fig. 5 is a view, partly in plan and partly in section, of certain parts shown in Fig. 4; and, Fi 6 is a plan view of certain parts shown in Fig. 3.

In the frame a is arranged the mechanism 1) for driving the reel 0 which carries the friction wheel at and which is journaled in the bearings e and f, the latter being an open bearing and being a part of a lever g fulcrumed at h and having the handle 2'. The friction wheel cl is adapted to engage the peri hery of the driving wheel 3' which is driven directly from the mechanism 1), and by pressing down on the handle i the shaft of will be raised and thereby move the friction wheel cl out of contact with the wheel In order to lock the handle i down, i. 6., hold the lever in such position that wheel (1 is out of contact with wheel 3', I provide the pawl 7c pivoted at l in the frame and having a in m which overrides a tooth n on the top of the lever 9; when the handle of the lever is depressed the awl falls forward and engages in front of the tooth n so that when the handle is released. it is prevented by the pin m from sufficient upward movement to allow reengagement between wheels (Z and j; in order to permit such reengagement, the operator presses down on lever i with his hand and then holds pawl l: back with his thumb before allowing the lever to rise un der the weight of the reel.

0 designates the bobbins arranged at the base of the machine and from which the threads 19 are taken. Between the bobbins 0 and the reel are arranged the measuring devices or clocks, one of which is shown in detail on Sheet 2 of the drawings and will now be described:

On the inclined rail q forming a part of the frame a is arranged a bracket 7" affording a bearing for the shaft 8 carrying the worm t and a peripherally grooved wheel a made of some such light material as aluminum, so that even if rotated at a high rate of speed, as intended, its momentum will be comp aratively low. A loop 42 carrying the weight w and arranged on the shaft serves as a brake. A slender arm ac pro 'ects horizontally from the bracket 1", the latter being somewhat in clined owing to the incline of the rail g, and extending laterally from the arm at is a pin y on the end of which, opposite the wheel a,

is fulcrumed the brakeshoe 2 carrying the slender upwardly extending faller 1. The arm as has an upwardly projecting portion 2 which carries the pin 3 on the end of which is arranged the thread guide 4 opposite the wheel u. The thread p on its way from the bobbin 0 is passed once around the wheel a, then over the thread guide 4 and then around wheel u again, and finally again engages the thread guide 4 and extends through the eyelet or faller 1. to prevent the windings of the thread around the wheel a from overlapping with each other, it being understood that the thread is passed around the wheel at least twice in order to secure such a frictional contact therewith as will insure the thread having a sufficient grip on the wheel so that the wheel will exactly partake of the advance of the thread. The brakeshoe 2 has a friction face 5 adapted to bear against the periphery of the wheel u and since it forms an eccentric curve it acts more or less on its first impact with the wheel to jam or bind therewith in bringing the rotating wheel to a stop, but lest this jamming or binding might cause the wheel to'collapse, it is prevented from pro ceeding beyond the safety point by the proj ection 6 of the brakcshoe which, once it contacts with the periphery of the wheel under the cam action of the brakeshoe, allows the brakeshoe to continue rather as a brake than as a cam, the wheel from then on having a sliding contact with the brakeshoe until it comes to a stop. The normal position of the faller 1 is the dotted line position shown in Fig. 3; should the thread break, the faller will fall into the full-line position, whereupon the brakeshoe will immediately act to stop the rotation of wheel a, the wheel 10 is the operating part of the clock and the brake mechanism which I have just described is peculiarly adapted to bring this wheel to a substantially immediate stop, when the thread breaks, as it is obvious will be necessary in order to of the amount of to the break.

The bracket r carries the auxiliary bracket 7 and in these brackets is arranged the longitudinally movable shaft 8 a spiral spring 8 interposed between a washer 9 on the shaft and bracket 7" presses a stop pin 10 in the shaft against the bracket 7, the shaft being capable of being pressed back by hand into a hole 11 in the rail q. On the reduced outer end 12 of shaft 8 is j ournaled the toothed wheel 13 and on the hub 14 of this wheel is journaled a toothed wheel 15, the wheel 15 having one more tooth than the wheel 13. On the projecting end of the hub 14 is secured the pointer 16 adapted to rotate with wheel 13. In the normal position of the parts, the wheels mesh with the 'worm t, but by pressing them back against the tensecure an accurate registry thread actually reeled prior The purpose of the guide 4 is sion of spring 8 the worm will be cleared so that the wheels may be manually rotated. The bracket 7 carries an arm 17 in which is pivoted a bifurcated pawl 18 which nor mally rests against a stop 19 and may be moved upwardly as far as the stop 20, said pawl straddling the peripheral portions of the toothed wheels; the wheels each carry a stop pin 21 which, when the wheels are rotated in the direction of the arrowin Fig. 4, may pass the pawl 18, but which will engage pawl 18 on the reverse rotation of said wheels to limit their backward movement. The wheel 13 has the scale 22, on which, by the aid of a stationary pointer 23 on bracket 7, the number of yards in fractions of ten yards may be read, and the wheel 15 has the index 24 from which by the aid of the pointer 16 the number of yards in hundreds may be read; for instance, the wheels being initially set with their stop pins 21 against the pawl 18, one complete revolution of wheel 13 would show one hundred yards reeled off, and this would be likewise indicated by pointer 16 on the index 24 of wheel 15 because, since this wheel has one more tooth than Wheel 13, the pointer 16 would be opposite the first point from zero on the index 24. It should be added that, since in order to reset the wheels they must be moved back out of engagement with the worm t, the pawl 18 is axially moved therewith on its pivot 18.

In starting and stopping the machine, since at these times the pull of the reel on the different threads is likely to be more or less irregular and hence might allow the fallers 1 to drop and apply the brake to the wheel u, with the result that the sudden stop of the wheels would break the threads, the lever f, is adapted to cause the fallers 1 to be temporarily held in the dotted line position shown in Fig. 3 so that the brakes cannot operate. Hence 25 is a rock shaft carrying the bent arms 26 which extend in front of the fallers 1. This shaft is ournaled in the brackets 27 and it carries a handle 28 and a plate 29 from which project two stop pins 30 and 31; the stop pin 30 bears against the top of the bracket 27 to limit the rotary movement of the rock shaft, on pulling upwardly on handle 28, past the position in which said handle stands in Fig. 2, while the stop pin 31 limits in a similar manner the downward movement of handle 28. A rod 32 is connected with the handle end of lever g and is passed freely through a lug 33 on the plate 29, having a nut 34 attached to its lower end. A spiral s ring 35 is interposed between a collar 36 fixec l on rod 32 and the lug 33. The arrangement is such that an upward pull on handle 71 of lever 9 will depress the bent arms 26 on the consequent rotation. of rock shaft 25, the bent arms holding the fallers up so that their brakes will not operate; if handle 2' is now lowered shaft 25 will return until its stop pin 30 engages the bracket 27, the spring 35 taking up any further downward movement of lever g.

In starting the reel, the operator first depresses lever g slightly until pin m clears lug n and then pushes back pawl k with his thumb, whereupon the lever g is raised, allowing the wheel (1 to drop into contact with the rotating wheel and causing shaft 25 to rock and its bent arms to push back the fallers so that their brakes are held out of contact with the wheels a temporarily. The upward pull on the lever g is now relieved, leaving wheels d and in contact and allowing rock shaft 25 to return to its normal position so that the fallers remain under the control of the threads. If a thread breaks, its faller would drop and on the ap lication of the brake the corresponding 0 ock would be brought to a standstill. The operator now stops the machine, in order to connect the ends of the broken thread, and in doing this he first depresses with one hand handle 28 so as to hold up the various fallers and prevent the brakes from operating on wheels u and then depresses lever to raise the wheel d out of contact with wheel j, pawl 7c falling for ward by gravity so as to engage lug n and hold lever g down when the pressure thereon is relieved. The pressure on handle 28 is now relieved, so that the rock shaft returns to its normal position under the action of spring 35, the operator thenproceeding to connect the ends of the broken thread.

On a shaft 37 below the wheels a are arranged the adjustable brackets 38 carrying the thread guides 39 acting to direct the threads accurately to the wheels 11., these guides and the guides 4 preventing such lateral movement of the threads as might cause them to work out of the grooves in the wheels.

One of the essential features of my invention is the means for stopping the clocks when the threads break. Heretofore much difficulty has been encountered in the effort to provide a mechanism which would stop even approximately instantly, so that the clock would not show more yards as reeled than were actually reeled. By using a driving member it of extremely light material and providing a brake mechanism such as that herein described, characterized particularly by the peculiarly shaped brakeshoe z, I find it possible to run the machine at an extremely high speed rate and yet be able to sto any clock almost instantly should a thread break. The pin y being slender and the brake 2 being mounted at the end thereof a certain undesirable rigidity of the brake is avoided, it being found in practice that if the brake is too rigid it is likely to grip the wheel it with such abrupt positiveness as to give rise to possible damage to the parts.

Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent is:

1. The combination, with registering mechanism, of a rotary drivin member for said mechanism having a circu ar periphery, said driving member being adapted to be rotated by the thread to be measured, and a pivoted thread-controlled braking device having a cam-like part engageable with the periphery of the driving member, said part having a relatively abrupt rise extending toward the periphery of the driving member, substan tially as described.
