MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 398,214, dated February 19, 1889.

Application filed November 13, 1888. Serial No. 290,662. (No model.)

To all 107mm it may concern.-

Be it known that I, ERNST F. AUTENRIETH, of New York, in the county of New York, and State of New York, have invented a new and useful Improvement in Mechanical Movements, of which the following is a specification, reference being had to the accompany ing drawings.

The object of this invention is to provide in a very compact form gearing for the purpose of transmitting rotary motion at a reduced speed.

I will now proceed to describe my invention in detail, and afterward point out its novelty in claims.

Figure 1 represents a. central vertical section of a driving-shaft and a portion of a driven-shaft having my invention applied. Fig. 2 represents a vertical section in the line a: m of Fig. 1 as viewed from the left. Fig. 3 is a plan of a portion of a wood-planing machine, illustrating the application of my invention thereto.

Similar letters of reference designate corresponding parts in all the figures.

A designates an internally-toothed spurgear, which is intended to be fastened in a fixed position to a stationary support-as, for instance, the framing B of the machine to which my invention is to be applied.

C designates afixed journal-box for the support of the driving-shaft D. This journal-box is arranged in front or outside of the gear A in concentric relation thereto. In the within the fixed internally-toothed spur-gear A. The hub f of this gear F is bored from one end concentrically to its pitch-line to reexample of my invention represented this,

ceive and constitute a bearing for the eccentric E on the driving-shaft D. This concen tric bore is represented in Figs. 1 and 2 as having fitted tightly to it a bushing, a, of hard metal, in which the eccentric is fitted to turn freely. The said hub is bored eccentrically from its other end to receive the shaft H to be driven, which I will hereinafter speak of as the second shaft, to which the gear F is firmly secured by any suitable means, as, for instance, a set-screw, b, as shown in Fig. 1.

The eccentricity of the second shaft, H, to its gear F corresponds with the eccentricity of the eccentric E to its shaft D. The second shaft, H, is in line with the driving-shaft D. It may be supported in any suitable bearings but I prefer that, as shown in Fig. l, the in ner end of the said shaft shall be fitted as a journal to a bearing, 0, made by boring the eccentric E, or the end of the driving-shaft D. In Fig. 3 the second shaft, H, is also represented as supported in bearings in the machine-frame B, the said bearings being indicated in dotted outline. The driving-shaft D is represented as furnished with drivingpulley, I, and this driving-pulley is represented as being furnished with a counter-balance, d, to counterbalance the eccentric E.

In order to provide for the oiling of the eccentric-bushing a and the journal-bearing c from the oil-cup e of the journal-box C, I provide in the shaft D, within the journalbox C, a transverse passage, 2', opposite the oil-hole of the cup 6, and through the eccentric E and shaft D a central longitudinal passage, j, which meets the transverse passage 2', beforementioned. I also provide in the eccentric a transverse passage, is, and I further provide in the second shaft, H, a ceno tral passage, Z, and a transverse passage, m, the latter passage being within the bearing 0. The oil flows from the oil-cup c and. journalboX through the passages ij 15 Z m, supplying oil to the eccentric through the passage 1c, and also supplying it to the journal Cthrough the passages Z and m.

The operation of the movement is as follows: Rotary motion being transmitted through the pulley I to the shaft D and eccentric E, the loo gear A is carried round by the eccentric E in an eccentric orbit within and in gear with the fixed gear A, and this motion within the gear A causes it to have a slow rotation about the common axis of the two shafts, and this rotation is also given to the second shaft, H, to which it is secured. The velocity of this rotation will depend upon the relative number of teeth within the gears A and F, being as the difference between the number of teeth in the two gears is to the number of teeth in the small gearfor instance, in the example represented there are thirty-eight teeth in the large gear A and thirty-six in the smaller one F, the difference in the number of teeth being two, and the smaller wheel of the shaft H making eighteen revolutions for every revolution of the driving-shaft D.

The example of my invention illustrated in Fig. 3 shows the movement applied to drive the shaft H of the first feed-roll, R, of the planing-machine. The driving-pulley I on the shaft D receives motion from a belt, J, from the pulley K on the shaft K of one of two cone-pulleys, L L, of which L derives motion from L through an intermediate frietion-wheel, M, which is capable of being adjusted lengthwise of the said cone-pulleys by means of a screw, N.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-- 1.. The combination, with an internallytoothed siationary gear, a driving-shaft concentric with said gear and an eccentric carried by said driving-shaft, of a second shaft arranged in line with the driving-shaft, a gear having fewer teeth arranged within and gearin g with said stationary gear and secured fixedly on the second shaft in eccentric relation thereto and containing a concentric bearing fitted loosely to the eccentric on the (hiringshaft, substantially as herein described.

2. The combination of an internally-toothed stationary gear, a driving-shaft concentric therewith and an eccentric carried by said driving-shaft, a second shaft arranged in line with the driving-shaft, a gear internal to and gearing with said stationary gear secured fixedly on the second shaft in eccentric relation thereto and fitted to the eccentric on the driving-shaft, and a bearing within said eccentric for the end of the second shaft, substantially as herein described.

3. The combination, with a driving-shaft, a stationary internally-toothed gear, and a journal-box for said driving-shaft secured concentrically upon said toothed gear, of an cecentric fast upon the said driving-shaft, a secon d shaft in line with the drivin g-sh aft, and an eccentric gear fast on the second shaft and fitting loosely to the eccentric on the drivingshaft, substantially as herein described.

4. The combination of an internally-toothed stationary gear, a driving-shaft concentric therewith, a stationary journal-box for said shaft, an eccentric carried by said shaft, a second shaft arranged in line with the d rivin gshaft, an eccentric gear secured to said second shaft in eccentric relation thereto and fitted to the eccentric on the driving-shaft, and a bearing within said eccentric for the end of the said second shaft, the said driving-shaft and eccentric having longitudinal and transverse oil-passages, and the said second shaft having longitudinal and transverse oil-passages, substantially as herein described, whereby oil is to be delivered from said stationary j ournalbox to the exterior of the eccentric, and also to the bearing provided within the eccentric for the second shaft, all substantially as herein described.
