The winding-stem D, preferably, is to be inelosed in the pendant-knob (not shown) of the movement-case, (not shown,) and is otherwise constructed and arranged of itself and in its connection (all not shown) with the pusherbutton (not shown) of the pendant-knob to be always in proper connection for being rotated and otherwise to serve all purposes, and as well known, the whole forming no part of this invention, and therefore, being well known, needs no further particular explanation herein. The mainspring-winding mechanism illustrated, Figs. 1, 2, and 4 to 0, both inclusive, in various forms of construction and arrangement of its several parts and in the special form of construction and arrangement of its several parts, Figs. 1, 2, 4, and 5, will now be described.

R S are two gear-wheels on maiuspringarbor B. The gear R is smaller than and is placed below the gear S, and it rests on a shoulder (t of the arbor B. The gear S rests on the pillar-plate, and both gears R S are loose and free to turn on arbor B.

T U are two ratchet-wheels of similar size and both fitting and engaging the mainspringarbor B and turning in common with it. This arbor B, as shown, is made square-sided, and each ratchet-wheel tits and engages the arbor.

T U are ratchet-wheels, one for each loose gear-wheel R S, and each ratchet-wheel is re ceived in a countersink or recess Z) of the upper face of the loose gear-wheels, and the teeth of both ratchet-wheels are presented in the same direction as to the axis of the arbor B, Figs. 1. and 2.

V \V are two pawls, each fnlerumed on a loose gear-wheel R S,and each at its free end engages the teeth of a ratchet-wheel T ll of its gear-wheel R S.

f is a bent spring, at one end fastened to the gear-wheels R and at its opposite and free end pressing against a pawl V \V.

The driving gear-wheel K, carried by the swinging yoke II, with said yoke in its normal position, meshes the smaller loose gearwheel R, and also a pinion gear-wheel X, which turns on a fixed stud X of the pillarplate and meshes the larger loose gear-wheel S. The rotation of the driving gear-wheel K directly rotates the loose gear-wheel R and the pinion gear-wheel X, turning both in the same direction, and indirectly through the pinion gear-wheel X it also rotates the loose gear-wheel S, but in a direction opposite to that of the loose gear-wheel R. If the direction of rotation of the loose gear-wheel R from the rotation of the driving gear-whe( K is such that its springpawl V engages the teeth of its ratchet-wheel'l,then said ratchele wheel will be thereby rotated in common with said loose gearwheel R, and through it, as it is engaged with the mainspring-arbor, as before explained, such arbor will be correspondingly and similarly rotated, while as the loose gearwheelS rotates in a direction opposite to that of the loose gear-wheel R, the teeth of both ratchet-wheels being, as stated, presented in the same direction, obviously the loose gear-wheel S will then simply turn on the niainspring-arbor, its spring-pawl \V freely passing and slipping over the teeth of its ratchet-wheel U. Again, if the direction of rotation of the loose gear-wheel R from the rotation of the driving gear-wheel K is such that its spring-pawl V passes and slips freely over the teeth of its ratchet-wheel T, then said ratchet-wheel will remain statimiary, and from the then rotation of the loose gearwheel S, which is in an opposite direction to that of the loose gearwheel R and in a direction for its spring-pawl \V to engage the teeth of its ratchet-wheel U, said ratchet-wheel and the mainspring-arbor are consequently rotated therefrom, and, as is obvious, in a direction which is the same as that of its previous rotation from the rotation of the loose gear-wheel R when its sprii'igpawl V did engage with the teeth of its ratchetwheel U. It thus appears that in either (lll't'K'ftion of rotation of the driving gear-wheel K the mainspring-arbor is rotated always in one and the same direction, and as the driving gear-wheel K receives its rotation from the rotation of the rotatory or pendant arbor D, plainly, in whatever direction that is retated, the 1nainspring-arbor is always rotated. in one direction only, whereby, it being of course understood that the so secured direction of rotation. of the mainspring-arbor is one suitable to secure a winding of the mainspring therefrom, the winding of the mailr spring is secured by a rotation in either direction of the winding-stem l).

The other forms of construction. and ar rangement of the several parts of the meclv anisms of this invention are now to be described.

In Fig. 6 each of the loose gear-wheels R S, with its pawl V \V and ratchet-wheels T l, turns on separate studs 10 and 1], of the pillar-plate, and both loose gear-wheels R S ongage the common driving gear-wheel K. The teeth of the ratchet-wheels T I are opposed relatively to the direction of rotation of the inainspring-arbor 13. Each ratchet-wheel has a fixed gear-wheel l2 13, in dotted lines, and the fixed gear-wheel 12 meshes gear-wheel '1 i, and fixed gear-wheel l3 meshes a gearovheel 15, turning on a fixed stud of the )illar-plate and meshing said gear-wheel H, which is fixed on the 1nainspring-arbor 13.

TlO

111 Fig. 7 the loose gear-wheel R, with its pawl and its ratchet-wheel T, is on, and the ratchet-wheel fixed to, the mainspring-arbor B, and the loose gear-wheel S, with its pawl NV and its ratchet-wheel U, is loose on a fixed stud 16 of the pillar-plate. Loose gearwheel R meshes driving gear-wheel K and loose gear-wheel S meshes a gear-wheel 17, turning on a fixed stud of the pillar-plate and meshing the driving gear-wheel K and a gear-wheel 241, fixed to the ratchet-wheel U of loose gearwheel S, which meshes a gear-wheel 18, turning on a fixed stud of the pillar-plate and meshing a fixed gear-wheel 19 of the mainspring-arbor B. The teeth of both ratchetwheels T U are presented in the same direction relatively to mainspring-arbor.

In both arrangements, Figs. 6 and 7, the turning of the driving gear-wheel K in either direction rotates the loose gear-wheels R S in opposite directions, and rotates the mainspring-arbor B in one direction only.

In Fig. 8 both loose gear-wheels R S, with their spring-pawls V \V and ratchet-Wheels T U, are on a common arbor 20, having a fixed gear-wheel 21, meshing a gear-wheel 22 of the yoke II, in turn arranged to mesh a fixed gear-wheel 23 of mainspring-arbor B. The loose gear-wheels R S are crown gearwheels, and both mesh a common bevel gearwheel 26 of the rotatory or pendant arbor D, and which gear 26 is located between them. The teeth of the ratchet-wheels are presented in the same direction relatively to the direction of rotation of mainspring-arb0r, and the loose gear-wheels R S rotate in opposite directions and the mainspring-arbor in one direction only.

In Fig. 9 loose gear-wheels R S (shown as bevel gear-wheels) have toothed clutchingrims 27 28, respectively, and all 011 a common arbor 29 of the pillar and top plates, having a fixed gear-wheel 30 to be connected to mainspring-arbor. Arbor 29 has two separate clutching-collars 31 32 to turn with, but to be free to slide-lengthwise on it. These clutchin g-collars 31 32 have a spring 33 between them and coiled about the arbor 29, all so as to engage both clutching-collars with their respective clutching rims of the loose gear-wheels, and to allow them to pass from and return to such engagement in the rotation of the loose gearwheels. The loose gear-wheels are in mesh with a common bevel gear-wheel 34: at opposite sides thereof and which rotates with the winding-stem D. Turning the rotatory arbor D in either direction turns the fixed gearwheel 30 of arbor 29 in one direction only, and through its connection (not shown) with mainspring-arbor that also is turned in one direction only. i

In turning the winding-stem D in one direction, one of the clutching-rims 27 or 28 of the loose gear-wheels R S takes hold of its clutching-collar 3]. or 32 of the arbor29, which is common to all, and the other clutchingrim 27 or 28 of theloose gear-wheels R S slips and passes freely over its clutching-collar 31 The loose gear-wheels R S turn in opposite directions.

All the constructions and arrangements of 1nainspring-winding mechanism shown and described embrace substal'itially the same elements and are substantially the same, varying only in forms of details and their arrangement. In each there are two loose gear-wheels and two ratchet or clutch wheels, and two pawls or clutches to engage said ratchet or clutch wheels, combined with said loose gearwheels and the mainspring-arbor and otherwise, as described, to secure a rotation of the two loose gear-wheels in opposite directions, and from them a rotation of the mainspringarbor in one direction only.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
