theI spring barrel and: the locking engage- :ment-,of the 1- same therewith, and which is also', ofra constructionthat the spring may beI readily removedfromA the spring barrel.
To the attainment of the yforegoing and other yobjects which will present themselves as'the nature of theinvention is better understood, reference isto be had tothe drawing.which accompanies and `which yforms part of'this application.
Figure 1 is a perspective view oi a partly wound spring held from expansion by a clamp in accordance with this invention.
Figure 2 is an approximately central longitudinal sectional view through a portion ot' the'spring and the connected ends of the clamp.
Figure 3 is a sectional view substantially similar to Figure 2, but showing the spring arranged in the spring barrel .and the eye or opening thereof engaging the anchor of the barrel. n
Figure 4 is a fragmentay perspective view of one end of a spring which has its end centrally notched and provided with hooks at the opposite sides of the notch for engagement with an anchor or with a pos t in a spring barrel, the dotted lines indicating the position of the improved clamp on the spring.
Figure 5 is a clamp. l
Figure 6 is a view of the end of a spring provided with diierent post receiving openings.
It is a common practice in factories for springniotor operated mechanisms, such as perspective view of the phonographs and the like, to wind the motor spring yto an extent that will render the same of a size to be inserted in the spring barrel.

manent aair, and the same must be re- The wire clamp is not a permoved when the spring is arranged in the barrel.. As the description progresses, it
will .be seen that my improvement contemplates the employment of a'permanent clamp for springs which are thus partly wound and which will slip with the spring into the barrel, permitting the outer end of the spring to be engaged by the anchoror post in the barrel and'in no way interfering with the operation of the motor.
Referring now to the drawing indetail, a partly wound spring is indicated by the numeral l. The spring has its outer end oti'setto provide a tongue extension 15 that is formed with a slot or opening 2 to en- .l
gage the post 3 in the barrel 4., The spring 1 has arranged therearound a comparatively thin metal strap 5. -The strap gradually decreases in width from Vone'to its opposite end and its widened end is provided with spaced openings 6. The reduced end of the ing 2 in the tongue 15 and has its extremity received in one of the openings 6 l and vis bent under the body of the strap proper@ is passed through the slot or openend of the spring and the coiladjacent to said tongue, so that the tongue may be forced toward the spring to permit of the latter being inserted in the barrel, when a release of such pressure on the tongue will allow the same to spring outwardly and to receive the post 3 in the opening 2 in the said tongue. Of course, the spring is turned inthe barrel either before or after the shaft issecured to the inner end thereof toV bring the post 3 into Contact with the outer end wall provided by the opening 2. I have found that by turning the barrel on its side and lightly tapping the same the springv will turn in the barrelso that'the post 3 will ride out'of the slotJ in the tongue.l It is to be noted that the opening 2 extends vthrough the inner end of the tongue 15 and enters the outer'end of the spring l. By providing the strap with a pluralityv of spaced openings 6, the samecan be adjusted for various sizes of springs.'
Certain ,springs employed Vfor operating motors have t eir outer ends centrally notched, as at 7 and the said ends, at the opiio t posite sides of the notch are hent upon themselves to forni hooks 8. These hooks 8 are en- Y gaged anchor rneinhers 9 in the spring,` barrel 10. in this instance, iny clamping strap :3 is arri nd the spring,` and the reduced of passed through the opening 7 so that iny permanent retaining,-
