This invention relates to a tool which is used by watch manufacturers and repair men for the purpose of setting springs in the spring cases of watches and the like. This is a very awkward and dificult operation because of the very small size of the parts to be handled and because of the difficulty to be experienced in getting the spring properly placed on its arbor without being in continual danger of the spring, springing out either at the arbor or from the upper portion of the spring case during the operation of setting the spring therein.
An object of my invention is to produce an improved tool in which springs of all slzes for watches or clocks may be accommodated and in which such springs may be wound very quickly on a temporary arbor and thereafter placed in their mounting cases without the least trouble. I
This and other objects are attained in the tool described in the following specification and illustrated in the accompanying drawings, in which;
Fig. 1 is a composite view of the parts of a tool embodying my invention, separated more clearly to show the construction thereof.
Fig. 2 is a perspective view of a spring, typical of the type I have chosen to which to adapt my improved tool, the spring being shown in a somewhat expanded position, with the inner and outer ends thereof pulled outwardly in order to disclose the characteristic means which is usually employed as a fastening at the end of the spring.
Fig. 3 is a view partially in section and elevation, showing the tool embodying my invention the improvements of which I will describe, with a spring mounted therein and in the condition it assumes after having completed the winding operation.-
Fig. 4 is a view, similar to Fig. 3, but showing the winding element of the tool removed and the setting element of the tool in position ready to place the spring therein.
Fig. 5 is a similar view as that of Fig. 4, but showing the element as having discharged the spring into the spring case.
1 am aware of the fact that a tool of the 1929. Serial No. 356,863.
general type I have disclosed, is not new and that such tools have embodied, generally speaking, such elements as the setting element, shown at the left in Fig. 1, and the winding element, shown at the right of Fig. 1. However, it is the winding element only to which I have applied the novel features of the invention I am about to describe. In
such tools of this type as are available on the market, the winding element is adapted to use with but one size of spring and great diiliculty to the operator in the endeavor to release the end of the spring from the fastener on the winding element is encountered, with much less of time, and the abuse to the end of the spring with pliers to release the end from the winding element; therefore, applicant knowing the difiiculties encountered in the art of spring setting, has so changed this winding element that not only more than one size spring can be accommodated thereon, but also to release the fastener from the spring end, without the usual difliculties or abuse thereto. The shaft of the present winding element is provided with a projecting pin adapted to engage the opening in the inner end of the spring to be wound, so that the spring, as the handle of the winding elements is turned, will be drawn into the housing of the setting element. In these tools noprovision has been made for rendering the construction adaptable to diiferent sizes of springs, neither from releasing the spring conveniently, after it has been wound.
In the tool I have disclosed, the setting element 6, as has been said, is identical with the setting element usually found in such tools, but the winding element 7 is different. The shaft 8 of the winding element is made movable to adjusted positions in which it may be locked by screw 9. This shaft is also made with a series of offsets of varying diameters l0 and 11 which form the shanks upon which the springs are wound. The smaller shank 11 fits, of course within the recess 12 of the longitudinally reciprocable plunger 13 of the spring setting element so as to form a hearing for the winding element. The shaft 8 is slotted longitudinally to contain a latch 14 which. is pivoted at a point 1.5 at the end of the shaft and extends outwardly beyond the crank 16 to form a small handle 17 by which the latch may be raised or lowered in the slot 18. On this latch are two pins, projections or lugs 19 and 20, the former extending above the periphery of offset 10 and the latter eX- tending above the periphery of offset 11 of the winding element shaft when the latch is in the raised position shown in Figs. 1 and 3, but which lie below the surface of the offsets when the latch is'pusheddownwardly to the bottom of its mounting slot. The purpose of 7 these lugs 19 and 20 is toengage within the opening 21 in the inner end of a coil spring such as handle22-otthe winding element is rotated, 1 .6; spring is drawn in to thehousing 23 of the settingelement 6, through the slot 24: in the setting element.
is shown in Fig. 2, so that as the movement with the offsets on said shaft, whereby movement of said latch engages or releases a spring located in said setting element. s
In witness whereof, I afiix my signature.
CURTIS MoFAR-LAND.
:If'thefdiameterof the inner opening of V the spring is too small for offset 10, then set screw 9 is released from the shaft 8 audit is slipped forward into. the winding element to renderonly offset 11 and lug 20 usable. De.- pressions 25 in-theshaftS at properly spaced intervals,afiord the means by which set screw g lockstheshaft in itsrequired positions of adjustment. After the spring winding has i beenco npleted, the'latch handle 17 is moved downwardly to withdraw the one of thelugs 19. or 20 which is causing the spring to be wound, thereby releasingthe spring and perinittingwthe entire winding element to be withdrawn from the setting element. x
The setting element has a plunger plate 26 suitably mountedwithin its housing 23 for control by the reciprocable plunger- 13 that when the springis beingwound as,
shown in Fig. 3, and at the time it is ready for discharge into thespring case, it occupies aposition againsttherear wall ofthev housing. In th's posltion the end of theplunger extends beyond the element 6: to form a push button 27 whichmay be pushed by the user of the t l i derto caus t plunge to force. the plate 26 toward the open end of the housing, thereby discharging the 7 spring intov the spring'case 28, as shown in Fig- 5, This latter description of the setting element does not incorporate anything of especial novelty inasmuch as the entire-setting'elementis of usual construction.
Havingthus described my invention, what I- claim is: Y
