UNITED STATES PATENT curios.
CLOCK-SPRING.
Specification of Letters Patent.
Patented Apr. 13, 1920.
Application filed August 24, 1918. Serial No. 251,291.
To all whom it may concern:
Be it known that L'MARTIN G. STAen BERG, a citizen of the United States, residing at Thief River Falls, in the county of Pennington and State 01 Minnesota, have invented certain new and useful Improvements in Clock-Springs, of which the following is a specification.
This invention relates to clock-springs, and the object is to so arrange the spring that it can be wound upon the winding-arbor of the clock without taking the works apart, thereby saving a great deal of time in repair work.
In the accompanying drawings:
Figure 1 is a view showing a portion of the clock-works with the spring partially wound upon the arbor thereof;
Fig. 2 is a detail view of the clock-spring.
1, indicates a clock-spring, one end of which is bent as at 2, and provided with an elongated slot 3 near its curved end. This end ordinarily is what is termed the inside end of the spring, but, as shown in Fig. 2, it is wound in such a manner as to be on the outside of the spring when the latter is coiled ready for shipment. The other end of the spring is formed in a loop 4, the outer free end being bent over upon itself and provided adjacent to its end with a headed rivet 5 which is adapted to be received into an elongated slot 6 in the spring proper, thereby forming a means for securing the opposite end of the spring when assembled in the works.
Ordinarily the spring when shipped is wound with the end 2 on the inside, which necessitates taking the works apart in order to assemble the spring upon the windingarbor 7. As shown in Fig. 1, this is obviated by winding the spring in such a manner that the end which is to be received upon the winding-arbor 7 is on the outside of the coil and in such a position as to be passed around the winding-arbor, whereupon the spring is uncoiled, as it were, and simultaneously re-coiled upon the arbor, until it is completely assembled thereon. Upon the completion of the winding, the opposite wrapped end of the spring is passed around the pillar 8 of the frame of the works and fastened in the usual manner.
It is obvious that I have arranged the spring in such a manner as to greatly facilitate the assembling thereof into the works in an expeditious and satisfactory manner, in fact in such a way that almost anyone at all handy can very conveniently install such a spring.
I claim:
A method of assembling clock-springs which comprises taking a spring, coiling it up with the inside or arbor end out, and the looped or stationary post end on the inside of the coil, then fastening the arbor end to the winding arbor, unwinding the coil, at the same time rewinding the coil about the arbor, and fastening the looped end to the stationary post.
In testimony whereof I afiiX my si nature.
