SPECIFICATION forming partl of Letters Patent No. 510,557, dated December 12, 1893.

Application inea september 21. 1892 To @ZZ whom t Be it known may concern: l that I, NowMAN M. SAATI, a

invented a new and useful Mechanical Movement, of which the following is a specification.

My invention relates to a mechanical movement adapted for reducing the rate of rotation in mechanical devices, and it consists in a othed wheel actuated by means of a branchthe alternate'engagement of the spurs of the the teeth at the opposite edges 4of the Wheel, to impart a rotary movement there- Figure 1, represents a top view showing one Fig. 2, represents an under view of the same.

and between the eccentric B and leve the Wheel C,

attached to a supporting plate F.

JWhen the shaft A is rotated in the direcby the arrow in Fig. 1, the diarranged opposite engaging spurs b, h', will be caused to move in the c tion shown metrically a g, toI alternate engagement ment With the teeth of the wh the spur b is in engagement of the wheel,

to in the direction of the a the continued rotation posite spur ment with the in the direction with the r D, and

is placed the bridge E, which is ircles g,

and disengageeelC; and when 6o tooth o,

movement will be imparted thereh will be brought into of the arrow thus ing motion to the wheel C in the sam tion as befo site' to that of the shaft A; and the co rotation of the shaft A, will canse the rrow and upon of the shaft A the opengagetooth @,which Nillbe moved imparte direc which direction will be oppontinued 7o continued rotation of the wheel C, tooth by tooth, 0'5"/ and upon the reversal of th ment of the ment will be i e rotary moveshaft A, a reverse rotary moveone or the other spu mparted to the toothed Wheel rs b, h',

times" in engagement with a wheel, so that the wheel cannot skip a tooth and thus with uncertainty.

Whenever it is tion of the shaft A same directi ment lever D may be on with each other, the

operate desired to cause the rotaand the wheel C in the engagemade of compound con struction, as shown by D in Fig. 7, so as to reverse the engaging movementof b, b', and th ment of the us cause the same r wheel C, as before; and

case the branching arms, ot, a, are p with the guide slot d and fulcrum stud e, and 9o with the circular socket z', to which is the leverj,

eccentric B, adapted to receive the fulc having a head when the shaft A is turned in the d of the arrow, the reverse engagemen studs b, h', struction of ver D, or D teeth of the the studs otary movein this rovided jointed y f adapted to fit the and provided with the slot 1c rum stud m, so that,

irection t of the by reason of the jointed conthe lever D', will drive the wheel wheel, that when the ecc with lthe shaft A. ,of the branching le- Ico are so arranged relatively tothe entric B space c between is in the position shown, the stud b will be in full engagement between the adjoining teeth at the side of the wheel, while the stud b is held opposite the point of a tooth, at the opposite side of the wheel.

Another arrangement for driving the shaft A, and the wheel C, in the same direction, is shown in Figs. 4c, 5, and 6, and in this case the lever D is also shown as adapted to make twice the ordinary number of vibrations, so that upon each complete vibration of the said lever, the wheel will be moved through the space of one-half of a tooth, instead of a whole tooth as before. The eccentric B instead of being placed upon the shaft A, is placed upon a driving shaft A', and at the side of the eccentric B is placed the pinion F, which engages with the gear G of twice its number of teeth, upon the shaft A. The eccentric B will thus be caused to revolve with twice the rapidity of the shaft A, and will also revolve in the reverse direction to that of the said shaft; and in order to move the wheel C for the space of one-half a tooth, at each complete vibration of the lever D, the engaging studs b,b', instead ot being pointed as shown in Fig. 1, are provided with a notch o, adapted to receive a tooth c, of the wheel, the said studs being at the same time of the proper thickness to enter the spaces c between the teeth, and when the shaft A is rotated, the stud b will first receive the top of a tooth c, and at the next vibration enter the the teeth, and so on, alternately, while the opposite stud b' will enter the space c', and at the next vibration receive the top of a tooth c, and so on, alternately, requiring two full vibrations ot the lever D, to produce a movement of one tooth in the wheel C.

Another modication of my invention is shown in Figs. S to 11, inclusive, in which a crown wheel C', is employed to turn loosely upon the shaft A, the eccentric B being attached to the said shaft; and in this case, the branching lever D may be employed to operate upon the inner side of the teeth c of the wheel C', the said lever being made to fit the eccentric B, and provided with the guide slot d adapted to receive the fulcrum stud e, and the branching arms a, a,

of the lever D are provided with the tapering spurs b, b', adapted to enter the spaces c' between the teeth ot the wheel C', to cause the revolution of the` wheel, by the alternate engagement of the said studs with the teeth c at the opposite edges of the wheel. The branching lever D, shown in Fig. 1, may also be employed with the crown wheel C', and in that case the rotation of the wheel C', will be reversed, when the shaft A is being rotated in the same direction as before.

This improved mechanical movement, is adapted for employment in Watches and clocks, and in various registering machines requiring a greatly reduced rate of movement, and several sets of toothed wheels with operating eccentrics `and branching levers, may be employed upon the same axis, as shown in Fig. 12, the second eccentric B being attached to the side of the wheel C', `and made to operate a lever D2, which engages with the teeth of the wheel C2, placed loosely either upon the shaft A, or upon the hub m of the wheel C', resulting in the greatly diminished movement of the wheel C2.

l claim as my invention- 1. lhe combination with the toothed wheel and the eccentric, of the lever fitting the eccentric, and provided with the two diametrically arranged spurs which by engagement rst with the teeth of one, and then the teeth of the other, of two opposite sides of the wheel, will cause the rotation of the said wheel, substantially as described.

2. The combination with the toothed wheel, ot the eccentric, and the compound engaging lever fitting the eccentric, and having spurs adapted to engage alternately with the teeth at the opposite edges of the wheel, substantially as described.

3. The combination with the toothed wheel, and the eccentric, of the engaging lever titting the eccentric, and having forked engagingspurs adapted to engage alternately with the points, and the sides of the teeth, at the opposite edges ot thewheel, substantially as described.
