ESCAPEM ENT.
SPECIFICATION forming part of Letters Patent No. 286,685, dated October 16, 1883 Application filed February 6, 1883.
The invention consists in the combination,
with a train of wheels and a spring for actuating the train, of a worm or screw engaging with and operated by one of the wheels of the train, a contrate escape-wheel on the shaft of the worm or screw, and an escapement-lever of novel construction engaging with said escape-wheel, and adapted to swing or vibrate in a plane coincident or parallel with the axis wheel and worm or screw, as more fully hereinafter described.
I11 the accompanying drawings, Figure l is a plan, upon an enlarged scale, of a watchmovement embodying my invention. Fig. 2 is a sectional view on the dotted line as :0, Fig. 1, looking in the direction indicated by the arrow. Fig. 3 is a view of a yoke for the escapement-lever which I may employ; and Fig. 4 is a perspective view, illustrating the relative arrangement of the worm or screw, the contrate-wheel, and the escapement-lev er.
Similar letters of reference designate corresponding parts in all the figures.
A designates the barrel, B the barrel-arbor, and C the mainspring, of a watch. Upon the barrel is a wheel, D, gearing into a pinion, a, on the arbor b, and on the said arbor b is a wheel, E, gearing into a pinion,pc, on the arbor d. On the arbor d is aspur-wheel, F, the teeth of which engagev with a worm or screw, G. This worm or screw, as here shown, has two threads, or is a double or multiple threaded screw.
The teeth of several wheels are not represented, save by dotted lines to indicate the exact diameter of the wheels. The worm or screw G is adapted to turn freely on pivots e, and upon the shaft thereof is secured a contrate or crown escape-wheel, H. (Best shown in Fig. 4.) I
(Modeld' I designates the usual balance-wheel, and f f designate, respectively, the hair-spring balance-pallet. The several arbors are journaled, in the usual way, in the plates J J of the movement. The escapement-lever is composed of a stock-piece or yoke, K, and an arm, K, forked so as to receive the balance-pallet f, and rigidly secured to the stock-piece ,or yoke K. The stock-piece or yoke K is annular in form, so as to receive the worm or screw loosely through it, as shown in Fig. 4, and it is provided with pivots g, which are here shown in vertical alignment. One of the pivots g has a bearing in the plate J, and the other has its bearing in a bridge, J attached to the plate J. On opposite sides of the yoke or stock-piece K, in horizontal alignment, are pallets h, upon which the teeth of the contratewheel H act, andthereby the arm K is vibrated in a plane parallel with the axis of the worm or screw.
In Fig. 4 the bearings in which the pivots g are journaled are not shown; but from Fig. 4 it will be clearly understood that by the teeth of the contrate-wheel H acting on the pallets h the lever K K is oscillated on its pivots 9'.
The stock-piece K may be greatly varied in form, and it need not necessarily embrace or case I use a contrate-wheel and a lever pro vided with an arm which is vibrated in a plane which is coincident with or parallel with the axis of the worm or screw.
What I claim as my invention, and desire to secure by Letters Patent, is a 1. The combination, with the train of wheels of a watch, of a worm or screw engaging with and operated by one of the train-wheels, a contrate escape-wheel on the shaft of said worm or screw, and an escapement-lever engaging with said escape-wheel and adapted to vibrate in a plane coincident or parallel with the axis of the contratewheel, substantially as described.
2. The combination, with the train of a watch, of a screw engaging with and operated by one of the train-wheels, a contrate escapewheel on the shaft of said worm or screw, and an escapement-lever composed of a yoke surrounding the worm or screw and an arm which surround the screw or worm; but in every is adapted to be vibrated in a plane parallel with the axis of the contratewheel, substantially as described. 3. The combination, with the contrate es 5 cape-wheel H and its screw-threaded shaft, of
the lever K K, made with a yoke which surrounds said shaft, and on which are both the pivots and pallets 0f the escapeinent-lever, substantially as herein described.
