Application filed August 14, 1929, Serial No. ssavsa'and in Grmanyoctober 22, 1927.

The present invention relates to improvements in reels of the type provided with swinging arms and employed for reeling on and off thread-like products such as yarn,

fine wire, rubber and the like.

In reels of this type the arms are simultaneously swung forward and backwards by a common driving means such as a traction rope engaging driving pulleys, wheels, connecting rods or cams, and one of the objects of the invention consists in arranging the driving means whether they comprise pulleys with traction rope or wheels or rods or cams in a casing serving as hub so that the driving parts are protected against coming in touch with fiber dus particles of yarn or dirt which drop down during operation of the rec To attain this end the casing is fully enclosed and the swinging arms are arrange therein or thereon in such a way that no apertures favoring the admission of dust during the swinging motion of the arms are produced. 1

According to the invention, thiscan be achieved in various ways. 'For example, the rotary parts forming the joint of the swinging arms may be of cylindrical shape and guided in cylindrical recesses provided at the circumference of the casing, the cylindrical part of the joint serving in this case as driving pulley. In this manner the easing remains fully enclosed in any position of the arms, because the cylindrical pivots 5' pack the cylindrical recesses tightly.

Furthermore, the swinging arms may be placed on journals projecting from all or alternate sides of the casing and carrying the driving means which are enclosed by the casing.

Another feature of the invention is the tangential bending of the swinging arms to enable them, during their backward motion, to hug the circumference of the casing enclosing the driving means. In this way, and especially on account of the tangential bending of the arms, the latter covers-a wide radi I us, as it is possible to extend the range from 1 the smallest diameter corresponding approximately to the circumference of the casing serving for receiving the yarn etc. One of the to the largest diameter which the ilengthiofi the. levers permits. l Several variations of arrangingthe swing- 1 ing arms in or on the casing aretillustratedin the accompanying drawings, in which Fig? .55- ure 1: isYa front view of 'a reel-.withbent swinging arms and cylindrical recesses at; the circumference of .the casingto receive the joints of the arms Fig.2, a side view of Fig: 1; Fig. 3,. a f'rontview of a reel, inlwhich the swinging arms encircle the casing portion like a bow and are arranged on journals projectingfrom' bothsides' of thewall of the casing; and Fig. 1, a side view of Fig. 3.

Referring to Figs. 1 and 2,.the reel consists chiefly of the fully enclosed casing 1 serving also as hub. Inside the casing the traction rope 2 is arranged which engages the pulleys 3 serving as joint portion and resting in cylindrical recesses 4L shut off on both sides by the wall of the casing. Through the'pulleys 3 extend the journals 5 secured to the side walls of the casing 1. The swinging arms 6 are rigidly connected with the pulleys 3 and curved so that on moving from the extreme position to the position 6 they hug almostcompletely the circumference of the easing 1. The swinging arms are provided with the stays 7 having any desired shape and journals 5 is threaded, and by tightening it by means of a fly nut the rotary parts can be braked more or less elastically or the swinging arms can be held in their position by fully tightening the journal and the fiynut.

As the cylindrical joint portions 3 are embedded in recesses 4: arranged at .the periphery of the casing 1, each armcan be swung about almost 180.

The same slewability combined with dusttight enclosed casings is found also in the modifications shown in Figs. 8, 4 and 5, the only difference being the absence ofrecesses on the periphery of the casing 1. On the other hand, the journals 5, as indicated in Figs. 3 and 4- extend from both sides of the casing 1 far enough to accommodate the bosses 9 of the swinging arms 6 so that a how 6 is produced which encircles the casing 1. i

I claim V 1. A reel comprising a dust proof casing, pivots constructed as rollers and arranged at the circumference of the casing, a common means acting on all of said rollers to drive the same simultaneously, curved arms secured to said pivots exterior of said casing, said arms being adapted to be collapsed and to hug said casing when said drive means is actuated in one direction, and to be extended and to lie away from said casing when said drive means is actuated in the other direction,

2. A reel comprising a dust proof casing, pivots journaled in the casing and projecting outwardly from said casing on each side of thesame, rollers enclosed within said casing and secured to said pivots, a common means acting on all of said rollers to drive the same simultaneously, curved arms secured to said pivots exterior of said casing, said arms being adapted to be collapsed and to hug said casing when said drive means is actuated in one direction, and to be extended and to'lie away from said casing when said drive means is actuated in the other direction.

In testimony whereof, I have affixed my signature.
