UNITED STATES CLARENCE EVERETT ULERY AND FRANK CARPENTER FITC or Tnnnnmi, TEXAS.
CLOCK ARBCR OR SHAFT.
Application filed April 3,
To all III/0771 it may concern:
Be it known that we, CLARENCE Evnnn'rr limit? and FRANK C. FITCH. citizens of the United States, residing at Terrell, in the county of liau'fman and State of Te 7 have invented a new and useful Clock arbor or iha'tt. ot' which the 't'ollowii'ig is a specification.
This invention relates to arbors or shatts for main and striking); springs or cloclrs.
The primary object of the invention is to provide an arbor of this class composed oi separable sections, so constructed and con-- nected that the springs mounted thereon may be quickly removed and replaced by another without disturbiira the frame or any other part.
With the foregoing and other objects in view which. will appear as the description proceeds. the invention resides in the combination and arrangement of parts and in the details of construction hereinatter described and claimed, it being understood that changes in the precise embodiment oi" the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.
In the accompanying drawings Figure 1 represents a side elevation of a cloc; arbor embodying this invention,
Fig. 2 is a vertical section thereof.
In the embodiment illustrated 1 and 2 represent respectively the front and rear faces of a cloclr in which is mounted the spring arbor or shaft 10 the spring 3 being attached to said arbor at its inner end by a pin shown at 13 in F 2.
The arbor 10 is constructed of a tubular main or body portion 10" with the bore thereof flared at its upper end to receive a tapered section 14- which detachably engages vith the flared portion of said bore. The tapered section or pin 1% has its pointed end 15 inserted in one end of the bore of section 1O which is correspondingly tapered to receive it and is secured therein by a cotter pin 17. The outer end of the pin 14 is made polygonal to receive the winding key.
A screw 18 is engaged with the other end of the arbor section 10 and is designed to hold this end of the arbor in a bushing 19 1924. Serial No. 704,000.
the lower face of which is mounted the main gear 12. This main driving gear 12 turns freely on the arbor 10 as usual in clocks of this character while the ratchet 11 operates to wind the spring.
In the use of this attachment when it is desired to remove the spring 3 for repairs or other purposes the cotter pin 17 is first withdrawn and then the screw 18 is removed. To separate sections 11 and 10 a rod or other punch is forcibly inserted through the open end of section 10 into the, bore thereof and given a light rap which will torce the tapered section let out pern'u ting the arbor and spring to be removed without interfering with any other parts of the clock. 7
It is of course understood that the arbor herein shown and described may be used in connection with either the main driving spring: or the striking spring or both and permits the quick replacement of a broken or set spring, without disturbing any of the other parts.
T he tapered pin. section 1 1 is telescopically engaged with the section 10, the pointed end 15 of r aid section let fitting in a seat in the end of section 10 which is correspondingly tapered to receive it, the cotter pin 17 passing through. both sections as is shown clearly in Fig. 2.
What is claimed is 1. An arbor oi the class described comprising a tubular section. another section telescopically engaging one end of said tubular section and detachably connected therewith and a screw threaded in the other end of said tubular section to form a bearing extension tor the arbor.
2. An arbor of the class described comprising; a tubular section having a bore flared at one end and a removable screw at the other end, a tapered pin section for insertion in the tapered flared end of said bore of the other section, and a cotter pin extending through the two sections for securing them detachably together.
In testimony that We claim the foregoing as our own, we have hereto afiixed our signatures.
CLARENCE EVERETT ULERY. FRANK CARPENTER FITCH.
