WINDING AND SPOOLING APPARATUS.

Specification of Letters Patent.

Application filed October 22, 1908.

Patented May 4, 1909.

Serial No. 459,087.

To all whom it may concern:

is journalcd a shaft B having -fixed to and Be it known that I, Janos Sonlinnrr extending axially therefrom a spindle 1 for NUSSBAUMER, a citizen of the Republic of the winding spoo s. The shaft is driven by Switzerland, residing at Erlenbach, near Zurich, Switzerland, have invented certain new and useful Improvements in Wmdmg and Spooling Apparatus; 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 or figures of reference marked thereon, which form a part of this specification.

In winding and spooling thread (which term I here employ in its general sense, intending therefore to include yarn) from bobbins, reels, or similar thread-delivering contrivances (hereinafter briefly referred to as bobbins), it frequently happens that owing to knotting, tangling, or jamming of the thread, or, in the event of the bobbins being wound in bulged form, owing to variation in diameter, the pull on the thread is temporarily increased, whereupon on the cause of such abnormal pull being overcome, the bobbin has the tendency to race, that is rotate in advance of the thread. Attempts have been made to remove this drawback by the provision of spring-mounted rollers, over which the unwound thread is guided. Such arrangement, however, is useless in the event of the thread breaking.

For the purpose of providing regulation even in the event of breakage of thread, I furnish for the bobbin an oscillating appliance which is influenced by the pull of the thread and serves to brake the bobbin, the braking action, however, being overcome again by the pull of the thread. Thus in the event of a sudden diminution of tension after increased pull of the thread, and also on cessation of the pull altogether, the appliance exerts a braking action on the bobbin and thus prevents racing of the latter.

One form of construction of the invention is illustrated in the accompanying drawing, in which Figure 1 is a side elevation, and Fig. 2 a front elevation of a duplex spooling machine. In the following description only one of the two devices shown will be considered, as both act in precisely the same manner.

In the construction shown in said drawings A designates a suitable bolster in which any suitable means such as a gear wheel I) fixed on one end and adapted to mesh with and be driven by a similar gear, not shown, on a suitable motor.

Mounted on and extending above the bolster A is a standard O having an arm 6, projecting at right angles thereto, to which latter is secured a bracket 0 in which is journaled a compensating pulley l yicldingl held against lateral movement by a spring o A short standard I) is mounted on the bolster A parallel to the standard O and has a horizontal pin (Z fixed in its upper end on which is ournalcd a pulley 3.

Bolted or otherwise connected with and depending from the arm 0 is a framing in the form of a yoke comprising two parallel arms 4 in the lower ends of which is journaled an axle 5 carrying a thread containing member 6 fixed thereto. Projecting from the inside of the arms 4 above the axle 5 are pins 7 on which is pivoted a cradle 8. On the end of the latter nearest to the standard O is suspended a weight 9 adapted to normally hold the opposite end of the cradle elevated above the plane of the thread container 6. In said elevated end is fixed apin 8 projecting parallel to the axle 5 serving as an axle for a roller 10. On one side of the cradle S is fixed a projection 11 adapted to serve as a brake shoe for the axle 5, said projection being fixed at a distance from the axis of pin 7 to swing in the arc of a circle which if struck from said axis as a center would pass through the axis of axle 5. The engaging face of the projection is preferably recessed or concaved to conform to the periphery of the axle for the purpose of increasing the size of the engaging surface of the shoe. thread runs from the container 6 over roller 10, pulleys 3 and 2 to the spool spindle 1.

The a If, now, at the bobbin 6 the pull of the thread I axis 5 and exert a braking action upon it, framing, having an arm extending parallel until the extent of draft of the thread is 1 to the spindle adapted to form athread guide again normal, or until the thread has been l and means on said support forming a brake pieced-up again.

Since the braking takes place directly at the bobbin, it is possible to very greatly increase the speed of the latter. The cradle 8 may obviously also be so constructed that both its limbs exert a braking action on the bobbin or its axis.

It is clear that the same braking device can also be employed for reels or the like, as well as bobbins.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that Wh at I claim is:

1. In a winding or spooling apparatus in which is combined a framing, a thread containing member mounted therein, a rockable support pivoted in the framing, a thread guide mounted on the support parallel to the thread containing member, said support adapted to serve as a brake for the thread containing member.

In a winding or spooling apparatus in which is combined a framing, a rotary spindle journaled therein, a bobbin fixed on the spindle, a gravitating support pivoted in the for the spindle.

3. In a winding or spooling apparatus, in combination, framing, a bobbin mounted thereon, a gravitating cradle pivoted to the framing, whose one limb constitutes a brake for the bobbin, and a thread-roller mounted 1 on the cradle above its pivotal points, substantially as described.

l. In a winding or spooling apparatus, in combination, framing, a bobbin mounted thereon, a U-shaped cradle having its vertical arms pivoted to the framing above the bobbin and located contiguously to the axis of the latter, and its horizontal loaded end located below the level of the bobbin, and a thread-roller mounted on the cradle above said bobbin and parallel with it, substantially as described.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
