HENRY ESSEX, OF MEADVILLE, PENNSYLVANIA.
GEARING.
SPECIFICATION forming part of Letters Patent No. 374,146, dated November 29, 1887.
Application tiled July 29, 1887. Serial No. 245,610. (No model.)
I 0 aZZ whom it may concern:
Be it known that I, HENRY EssEX, of Meadville, in the county of Crawford and State of Pennsylvania, have invented a new and useful Improvement in Multiple Gearing; and I do hereby declare that the following is a full, clear, and exact description of the same.
My invention relates to mechanical movements,and is an improved form of mechanism for converting motion, the initialfspeed being multiplied in its transmission or reduced, as circumstances may require.
My invention consists in its broadest features of a driving gear-wheel, a double gearwheel, or a series thereof carried loosely on the support with the driving gear-wheel, the double gear-wheels having large and small portions and a similar double gear-wheel or series thereof on another support, the large portions of one series engaging with the small portions of the other series.
The drawing represents the two supports and the train of gears mounted thereon.
The supports are marked A B, of which the support A carries the single driving gear-wheel O andthe double gear-wheel D, and the support B carries the double gear-wheel Eand the single driven gear-wheel F. Any suitable journals and boxes may be provided for these shafts. The driving spur gear-wheel Oou the support A meshes into the small portion of the double gear-wheel E, running loosely on the support B,and thelarge portion of said double gear-wheel E meshes in turn into the small portions of asimilar double gear-wheel,D,ruuning loosely on the support A and positioned similarly to the said wheel E. The large portion of the double gear-wheel D meshes into a small spur-wheel, F, on the support B, or it could mesh into the small portion of another similar double gear-wheel instead,and so continue gearing from wheels on one support to similar wheels on the other indefinitely to produce any speed desired. The opposite action would reduce speed indefinitely also.
Instead of employing rotary shafts, as described, the supports may be mere bars or standards, in which case all the wheels would be mounted loosely; or, if desired, one of the supports may be stationary and the, other rotary. The last single gear-wheel may be dispensed with, ifdesired, and the motion derived from the last double gear-wheel. The starting and ending gears can both be fastened to their respective shafts, or one can be fastened and other loose, or both can be loose, in which case the intermediate double gears may be, if desired, fixed to their shafts.
Having thus described my invention, what I claim is- 1. In combination, the driving-gear O, the two supports, the double gears, as E D, each being formed with larger and smaller portions and mounted on their supports in similar positions, the larger portion of one gearbeing in engagement with the smaller portion of the opposite gear, and the remaining portions be ing free to engage with other wheels, substantially as described.
2. In combination, the two supports, the driving'gear 0 upon one of said supports, the gear, as F, also mounted upon one of said supports,and theintermediatedouble gearsloosely mounted upon the two supports,the large portion of one double gear meshing with the small portion of the opposite gear, and the remaining portions being free to engage with other wheels, substantially as described.
In testimony whereofIhave signed my name to this specification in the presence of two sub scribing witnesses.
HENRY ESSEX.
