UNITED STATES EDEN MILTON BALLANTINE, OF PHILADELPHIA, PENNSYLVANIA,
SHUTTLE-SPINDLE SPRING.
Application led September 16, 1924. Serial No. 738,102.
To all whom t 'may concern.'
Be 1t known that I, EDEN M. BALLnN'rrNn,
a citizen of United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Shuttle Spindle Springs, lof which the following is a specification, reference being had therein to the accompanying drawing.
The present invention relates toloom shuttles having bobbin spindles mounted there` in to be swung out of and into the shuttles for the replacement of the bobbins thereon, and it is the object of the invention to provide novel and improved spring means for effectively retaining the spindle in position within the shuttle.
With the foregoing and other objects in view, which will'be apparent as the description proceeds, the invention resides in the construction and arrangement of parts as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without dei parting from the spirit of the invention.
The invention is illustrated in the accompanying drawing, wherein- Figure 1 is a View, partly in elevation and partly in section, showing the improved spring means as embodied in a shuttle of conventional design. l
Fig. 2 is a fragmentary plan view show ing the springs.
The shuttle 7 which may be of any well known construction, has an opening in which the bobbin spindle S is normally disposed longitudinally or axially of the shuttle, and said spindle has a shank 9 inserted through the spindle socket 10 which is pivotally mounted on a transverse pivot pin 11 eX- tending through the shuttle, so as to permit the spindle to be swung out of and back into the openingof the shuttle with the socket 10. The shank 9 has the opposite notches 12 at opposite sides of the pivot pin 11 to engage transverse stop pins 13 engaging through the shuttle, whereby to limit the movement of the spindle in one direction whenV swung into normal position within the shuttle, one pin 13being beyond the rear end of the socket 10, and said socket having the recess or opening 14 to accommodate the other pin 13.
Ordinarily, a leaf spring 15 is provided for holding the spindle 8 and socket 10 in position within the shuttle, said leaf spring 15 being secured to the shuttle 7 by a secur mg screw 16 or other securing element with ing a seat 17, and the Afree terminal of the spring bears against a contact portion or lug 18 of the socket 10 so as to exert pressure against the socket to swing the socketand the spindle and hold the spindle against the pins 13, Such spring has been a source of annoyance because the spring may weaken and permit the Aspindle to vibrate or swing out of normal position. The parts described up to this point areV common and well known in shuttles, and in order to increase the power and efficiency of the spring means, an additional or supplementary spring is used as will presently appear.
A leaf spring 19 is secured against the leaf spring 15 within the seat 17 by the screw or securing element 16, and is longer than the spring 15 so as to extend beyond the free end ofsaid spring 15. The free terminal of the spring 19 is bent back inwardly, as at 20, in, hook formation so as to bear against the contact point or'lug 18 of the spindle socket, with the spring 15 located within the hook portion of the spring 19 and bearing against the terminal portion 20. Thus, both springs exert pressure against the spindle socket to hold the spindle in proper position within the shuttle, and by disposing the bent back terminal 20 of the spring 19 between'the spindle socket and spring 15, the strength and holding power' of the spring means is increased considerably and is more efficient.
The spindle can be swung out of the shuttle and removed conveniently. Thus, by swinging the spindle (upwardly as seen in Fig. 1) the spindleis swung away from the pins 13, and the contact point or lug 18 will, by cam action, bend the springs 15 and 19 outwardly, the spindle 8 being readily withdrawn from the socket 10 as soon as the spindle is swung out of the shuttle away from the pins 13.
The supplementary or additional spring 19 can be readily applied to shuttles already in use, by using the same securing screw or element 16 which fastens the spring 15 to the shuttle, and inserting the end portion or terminal 20 between the spring 15 and spindle socket. As shown, the springs 15 and 19 have the enlarged portions 21 surrounding th-e apertures through which the screw 16 extends, and said springs lia-ve the tail poi-tions 22 extending beyond the poi'- tions 2l. 1
