WATCH.
SPECIFICATION forming part of Letters Patent No. 763,508, dated June 28, 1904.
Application filed April 25, 1903.
To a, whom it may concern:
Be it known that I, BERNARD REDEPENNING, a subject of the Emperor of Germany, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Watches, of which the following, when taken in connection with the drawings accompanying and forming a part hereof, is afull and complete description, sufiicient to enable those skilled in the art to understand, make, and use the same.
This invention relates to ordinary watches; and the object of the invention is to obtain a watch intended to be wound every twentyfourhours which will run at nearly the'same rate of speed the last few hours of the twentyfour following its being wound as during the first few hours after such winding.
The manner in which I obtain, particularly in a cheaply-made watch, a nearly uniform speed during the twenty-four hours subsequent to the winding thereof is by so constructing the watch and so positioning the parts thereof relative to each other as to permit the use of a much wider and longer mainspring'than is usually employed in watches. By constructing the watch in a manner embodying the inventions set forth and claimed herein 'I find I can use a mainspring of less force than is ordinarily used, it being of sufficient length, however, to run a watch in the neighborhood of forty eight hours after winding.
In the drawings hereinbefore referred to, Figure 1 is a top plan view of a watch embodying my invention. Fig. 2 is a sectional view on-line 2 2 of Fig. I viewed in the direction indicated by'the arrows. Fig. 3 is the plan view of the under side of a mainspringbarrel bridge used by me in this invention. Fig. 4 is an elevation of the mainspring-barrel bridgeillustrated in Fig. 4. Fig. 5 is a sectional view of the winding and setting stem, showing in elevation the winding gear-wheel which is loosely mounted thereon; and Fig. 6 is a sectional view showing the circular projection' on the bridge which is attached to the back plate of the watch and the circular hole in the mainspring-barrel loosely fitting over Serial No. 154,260. (No model.)
- such circular projection, such barrel turning on the projection.
A reference-letter applied to designate a given part is used to indicate such part throughout the several figures of the drawings wherever the same appears.
A is a short section of the watchcase, and a is the stem thereof.
' B and C are the plates of the works of the watch.
D is the mainspring-barrel bridge. E is an additional bridge used by me in the construction embodying this invention attached, as by the screws 0 c, to the back face of the plate C.
F is the barrel-arbor of the mainspring, and G is the mainspring-barrel.
G is the mainspring. The mainspring-barrel extends through the plate B to obtain a Wide mainspring.
H is the barrel-arbor wheel or the first wheel of the train of the watch and is rigidly secured on the barrel-arbor F to turn therewith.
l is the pinion of the train of the watch. which intermeshes with the barrel arbor wheel H.
2' is the shaft on which the pinion I is rigidly secured, and I is the cannon-pinion carrying the minute-hand 71 of the watch. Cannon-pinion I is on the shaft 6 and turned by friction in the ordinary way. It will be observed by reference to Fig. 2 that one end of the shaftz' is journaled in bridge E to permit the mainspring-barrel G to extend over and beyond the shaft.
g is the axial center of the mainspring-barrel G, and h is a projection on the under side of the mainspring-barrel bridge D, on which projection the mainspring-barrel turns when the watch is being wound. The mainspring barrel-arbor F and the mainspring-barrel G are not concentric, as is readily seen by inspection of Figs. 1 and 2, and hence the diameter ofthe mainspring-barrel is greater than the diameter of the barrel-wheel H.
J is the wheel and pinion transmitting motion from the cannon-pinion I to the pinion J of the hour-hand of the watch.
K is a dog engaging with the teeth w on the spindle to be moved longitudinally therethrough. Gear-wheel N is also provided with the recesses 91 a on the face thereof adjacent to the pin or projection 0, such recesses having,*respectively, one inclined face and one face against which the pin or projection O abuts to turn the gear-wheel forward with the spindle when such spindle is rotated. When the spindle M is rotated in one direction, with the pin or projection O in contact with the recessed end of the wheel N, such wheel is turned with the spindle, and when such spindle is turned in the opposite way such wheel is not turned therewith.
M is a gear-wheel engaging 'with wheel N and with the gear-teeth n on the mainspringbarrel Gr, so that the watch is thus wound by turning the spindle M in the ordinary way.
P is a gear-wheel rigidly secured to the spindle M to turn therewith, and Q is a gearwheel rigidly secured on shaft (1 inposition relative to gear-wheel P to intermesh therewith when the spindle M is forced forward against the resiliency of the spring m.
g is a gear-wheel rigidly set on the shaft (1 in engagement with the wheels J, so that as the spindle M is turned (when forced in against the resiliency of spring 711/) the hands are set.
R indicates a recess in plate B, through which recess the wheel N extends and by which such wheel is prevented from moving forward when the spindle is forced forward to bring the wheel P into engagement with the wheel Q.
By turning the mainspring-barrel to wind the watch and the mainspring barrel-arbor to run the watch such mainspring is wound frolm one end and unwound from the other enc. Y
The barrel-arbor, with the wheel H thereon, is in substantially the same position as in an ordinarily-constructed watch; but by shortening the center pinion, as hereinbefore described, and by inserting the bridge D and putting the mainspring-barrel through the aperture in the plate B, I obtain suflicient room to use a wider mainspring than is ordinarily used, while at the same time the mainspring and the mainspring-barrel extend over the center pinion i of the watch. I thus place a wider and a longer mainspring in the watch than is customarily done, such mainspringbarrel being of more than half the diameter of the plates of the watch. I have used a mainspring of the running capacity of fortyeight hours. I do not, of course, in a watch designed to be wound every twenty-four hours require a mainspring of forty-eight hours running capacity; but I obtain greater uniformity in the movement of the watch by so doing, and in case it be forgotten to wind the watch at the regular time such longer running capacity is utilized to prevent the watch from stopping as soon as it otherwise would.
By placing the mainspring-barrel eccentric to the barrel-arbor it is of course nearer one of the walls of the barrel than it is to the other and opposite wall thereof; but this does not interfere with the running of the watch in any way, as in all mainspring-barrels the spring is on one side or the other thereof, and Imerely utilize such fact in constructing the watch as herein described.
Having thus described my invention and the construction of a watch embodying the same, what I claim as new, and desire to secure by Letters Patent, is
1. In a watch, the combination of a mainspring barrel and a mainspring arbor set eccentric to each other, such barrel provided with a circular hole inone end thereof, a bridge provided with a circular projection on one side thereof to fit loosely in the circular hole in the end of the barrel, an additional bridge attached to the back of the front plate of the watch, the mainspring-arbor arranged to extend through the mainspring barrel and to be rotatably mounted in such bridges, a center pinion and a gear-wheel on the mainspring-arbor intermeshing with such center pinion; substantially as described.
2. In a watch, front and back plates, bridges on the back of the respective plates, a mainspring-barrel and a mainspring barrel-arbor set eccentric to each other, the back plate being provided with an aperture through which the barrel extends to near the bridge thereover, and such barrel-bridge being provided with a circular projection on which the barrel turns when the watch is wound, a center pinion journaled at one end thereof in the bridge on the back of the front plate, a gear-wheel rigidly secured on the mainspring barrel-arbor to intermesh with such center pinion; all substantially as described.
3. In a watch, the combination of a main-' spring-barrel and a mainspring barrel-arbor set eccentric to each other, a mainspring, a gear-wheel rigidly secured on the barrel-arbor to intermesh with the center pinion of the watch, and means to turn the barrel to wind the mainspring; substantially as described.
