WATCH-WINDING ATTACHMENT.
Specification of Letters Patent.
Patented A119. 2, 1921.
Application filed. November 14, 1919. Serial No. 338,06S.
To all whom it may concern:
Be it known that I, ELMER C. NIELSEN, a citizen of the United States, residing at Rawlins, in the county of Carbon and State of Wyoming, have invented certain new and useful Improvements in IVatch-VVinding Attachments, of which the following is a speci fication.
This invention relates to improvements in watch winding attachments especially adapted to be applied to main spring winders.
An important object of this invention is to provide a watch winding attachment which may be readily applied to a main spring winder and which may be sold as a part of the main spring winder so as to increase the utility and salability of the same.
A further object of this invention is to provide a watch winding attachment for main spring winders having novel means for engaging the winding stem of the watch so that when the winding of the watch is completed the stem will lose its binding contact with the device, whereby over winding of the watch is prevented.
A further object of the invention is to provide a device of the class described which is simple to use, of highly simplified construetion and cheap to manufacture.
Other objects and advantages of the invention will be apparent during the course of the following description.
In the accompanying drawing, forming a part of this application and in which like numerals are employed to designate like parts throughout the same,
Figure 1 is a side elevation of a main spring winder having the improved attachment applied,
Fig. 2 is a detail section through the attachment applied,
Fig. 3 is a fragmentary perspective of the attachment.
In the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 5 generally designates a main spring winder having its lower portion provided with a shank 6 which is reduced, as indicated at 7, for providing an attaching lug adapted to be received between the jaws of a watchmakers vise. The upper portion of the device is provided with alined barrels 8 and 9, the barrel 9 rotatably receiving an operating crank 10 having a handle 11 and provided with a fixed collar 11' retaining said crank against axial displacement toward the barrel As iswell known, these devices are employed for winding the main springs of watches prior to fittlng them within a watch 'ase. In this particular style of device the main spring engaglng and supporting means are corinectcd to the forward end of the shaft or crank 10 whereby the rotation of the crank causes the spring to be wound.
To provide for the attachment of the improved watch winding attachment the main spring engaging and supporting means are detached from the forward end of the shaft 10 and the forward barrel 8. The improved watch winder includes an arbor 12 having its rear end portion provided with a longitudinally extended socket 13 receiving the reduced forward end portion 14 of the shaft or crank 10. The reduced forward end por tion 14; of the crank is held within the socket by a set screw 15 which seats against a recess in the reduced end portion 14 for causing the rotation of the arbor with the crank. The intermediate portion of the arbor 12 is enlarged to provide a bearing 16 which is rotatably extended through the barrel 8 and is held within the same by a locking sleeve 17. As will be noted with reference to Fig. 2, the sleeve or collar 17, which is secured to the shaft by a set screw 18, engages the rear side of the bearing 16 and the rear side of the collar 8 so that undue longitudinal movement of the arbor is prevented. The forward portion of the arbor is provided with a socket 19 which is of a greater diameter than the bearing 16 and engages the adjacent side of the barrel 8 for coacting with the collar 17 in securing the arbor in position. The cylindrical socket 19 is provided with a filling 20 of partly or fully cured rubber which may be cemented or otherwise secured in position and which is provided in its outer side with a recess 21 conforming in curvature to the curvature of the stem 22 of a watch 23.
After one or.more watches have been repaired and it is desired to wind the same, the stems 22 may be inserted into the recesses 21 for providing frictional contact between the stem and the filling of rubber, whereby when the crank 10 is 'manually rotated the socket 19 will also be rotated for winding the watch. The rubber filling provides a frictional contact between the arbor 12 and the stem to assure the complete winding of the watch. However, when the watch is fully wound the frictional contact between the stem and the rubber will be insufi icient to allow the watch to be overwound. In the event that the operator continues to rotate the crank 10 after the watch is fully wound, the rubber will merely slip about the stem 22 and will not further rotate the latter.
This attachment may besold with the original main spring winder or as a separate part thereof. Also additional rubber fillings 20 may be provided when the original one becomes worn.
' It is to be understood that the form of the invention herewith shown and described is to be taken as a preferred example of thesame and that such minor changes in arrangement and construction of parts may be made as will remain within the spirit of the invention and the scope of what is claimed.
Having thus described the invention, what is claimed is:
1. A watch winder comprising a standard having'alined barrels, a crank including a shaft received in one of said barrels, means retaining said shaft against axial d1splace- 'ment toward the other barrel, awinding arbor mounted in the other barrel and hav- 7 ing means retaining the same against axial displacement toward the crank shaft, and cooperating means carried by the shaft and arbor for detachably associating the two in driving relation.
2. A Watch winder comprising a standard having aline'd barrels, a crankincluding a shaft received in one of said barrels, a collar the shaft and arbor'in detachable driving relation. v i
3. A watch winder comprising a standard havingalined barrels, a crank including a shaft received in one of said barrels, a collar on said shaft preventing axial displacement of the latter in the direction of the other barrel, a winding arbor mounted in the other barrel and having'a watch winding socket bearing against the barrel to prevent axial displacement toward the crank shaft,fa collar onsaid arbor bearing against the other side of the same barrelto prevent displace ment of the arbor away'froin thecrank shaft axially, a reduced end portion on the said crank shaft, said arbor having a socket receiving said end portion, and a set'screw in said arbor socket spotted into saidreduced end portion whereby said arbor and crankshaft are detach-ably associated in driving relation.
In testimony whereof I affix my signature.
