MEANS FOR SETTING END STONES IN WATCHES.
Application filed March 1, 1924. Serial No. 696,297.
To @ZZ whom it may concern:
Be it known that I, BERNARD t3. CoDDING, a citizen of the United States, residing at Warren, in the county of Cochise and State of Arizona, have invented new and useful Improvements in Means for Setting End Stones in lVatches, of which the following is a specification.
The object of this invention is to provide means adapted to set an end-stone eccentrically with reference to a conical pivot or staff of a watch, and with reference to the jewel in which the pivot is mounted, for rotation.
A further object is to provide an eccentrically mounted end-stone which may be rotated slightly when it has become pitted, so that a new surface will be presented, and the refinishing or renewal of the stone will not be required.
A further object is to avoid the loss of time incident to the operation of renewing or refinishing a stone of this kind, and likewise to avoid the expense involved.
YVith the foregoing and other objects in view, the invention consists in the novel construction and arrangement of elements described, illustrated and. claimed, it being understood that modifications may be made within the scope of the claims without departing from the spirit of the invention.
The stones provided for reducing friction and end thrust of certain of the pivots in all grades of watches designed for eiiicient service, are subject to wear, and when they become pitted, complete and satisfactory repairs can only be made by renewing the stones. In order to avoid this expense, refinishing or some other expedient is resorted to, for partly meeting the difliculty. My
purpose is to provide a stone the position of which may be changed almost instantly, for presenting an entirely new surface, without' removal, with the result that the bear ing will then function as correctly as when new.
It is difiicult to ascertain the extent of repairs required when a watch is presented by a customer for attention, and the watchmaker frequently finds .later that complete repairs will be more expensive than was anticipated, or if made within the estimate, the results will be unsatisfactory. This difficulty is also avoided under the conditions here disclosed.
In the accompanying drawings, Figure l a view in section through a hole jewel, an end stone, and the settings therefor; Figure 2 is a plan view The element in which the settings are mounted is designated l, and this element is machined to receive the detachable members which are held in position by screws 2. An end stone is desigated 3, and the sets ting therefor is shown at 4. The setting 5 for the hole jewel 6 has an outer flange 7 engaging iiange 8 of element 1, for prevent* ing movement in one direction.
The setting 4: is of greater diameter than setting 5 and therefore the bore 9 for setting l is correspondingly greater than the bore l0 for the other setting. These bores and settings are eccentric with reference to each other, and the settings, as well as the stone and jewel, are likewise eccentric with reference to each other. The drawing shows that the screws 2 engage the setting il, and the latter holds the setting of the jewel, the two settings being in contact when the stones are in contact.
When the end stone 3 becomes pitted, it is only necessary to rotate the setting 4- very slightly in order to present an entirely new surface, and restore the original conditions, without expense for this particular item, and with the assurance of satisfactory results. In view of the large number of new positions possible, this operation may be repeated a great number of times with equal success.
It is unnecessary to add that this type of mounting may be employed in connection vith endstones wherever used, as in other time keeping devices, speedometers, electric meters, and the like.
Vshat I claim is:
l. The combination with a watch jewel and a setting therefor, of means for mounting the setting, said means having a bore eccentric with reference to the setting, an end stone, and means for mounting the end stone concentrically with the bore and eccentrically with reference to the jewel.
2. The combination with an element having a plurality of bores eccentric with reference to each other, a jewel and a setting therefor mounted in one of the bores, of an end stone and a setting therefor mounted concentrically in the other bore and eccentrically with reference to the jewel.
3. The combination with an element havmeme 'or retaining the setting; of the ent! mg a, plurality of 1901765 @00mm-ic. with perfstom :mit heldngj Ithe latter in Contact with erenee to each other, a jewel and :1 setting the setting' of they Jewel when the end stone 10 therefor mounted in one of the bores, ot an engages the jewel. end stone and a setting therefor mQunted In testlmony whereof I am); my Slgna eoncentreally in the other bore and eeeen- UI'G- L( treally With reference to the jewel, and BERNARD S. CODDING.
