JOHN I. MANNY, OF ROCKFORD, ILLINOIS.

IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 38,054, dated March 31, 1863.

Z all whom it may concern,.-

Be it known that I, JOHN P. MANNY, of Rockford, in the county of Winnebago and State of Illinois, have invented a certain new and useful Improvement in Gearing for Harvesters, of which lthe following is a full, clear, and exact description, reference being had to the accompanying drawings, which make part of this specification, and in whichl Figure l represents a horizontal section` through the driving-wheel and gearing of a harvester to which m y improvement is applied; Fig. 2, a View in perspective of the outer side of my improved driving-wheel, and Fig. 3 a similar view of the other side of the same.

My improvement consistsin mounting the spur-pinion and bevel-wheel upon an overhanging or projecting bearing in such manner that the bevel-wheel sh all be between the driving-wheel and gearing-frame, and yet outside ofthe plane of the driving-wheel, while the crank-shaft has its bearings upon the frametimber, as hereinafter described, whereby I am enabled to secure a simple, strong, 4and compact arrangement of the gearing, and consequently to reduce the width of the gearframe.

In the accompanying drawings a stout frame, A, is shown as encompassing a driving-wheel, B, which turns on suitable bearings in it. The driving-wheel has a concave or depression on its outer face, in which an internal spur-wheel, C, is bolted. A counter-shaft, D, is mounted in a long box, E, rmly secured upon the outer frame-timber. A spur-pinion, F, and bevel-wheel G are mounted upon the end of this sha ft. In this instance the spurpinion and bevel-wheel are represented as cast in one piece and with a concavity in the face of the bevel-wheel, into which the projecting end of the box or bearing E lits. The spur-wheel O engages the spur-pinion F, thus driving both it and the bevel-wheel G, which in turn drives a bevel-pinion, H, on a crankshaft, I, mounted in suitable bearings on the gear-frame. Thebevel-wheel and spur-pinion are shown as keyed upon and turning with the counter-shaft, which method I prefer; but it is obvious that the counter-shaft might be rigidly fastened to the frame, and the pinion and wheel be made to revolve upon it, if desired.

The following are some of the advantages attained by the use of my improvement, viz:

First. The outside frame-timber (which was only necessary to support the outer journalbox of the counter-shaft, which box was always outside of the bevel-wheel) is dispensed with.

Second. The frame is rendered more compact and strong, and consequently not so liable to sag or twist, and thus strain the gearing.

Third. The wheels, being firmly secured together, must always run true to each other.

Fourth. When thus united, it follows that the driving-power is applied to the bevelwheel directly from the spur-pinion. The counter-shaft is thus relieved from torsion or strain, and the friction consequently reduced.

Fifth. The machine is rendered stronger, cheaper, more simple, compact, and durable, and the attractiveness of its appearance is increased. f

Sixth. By dishing the face of the bevelwheel the length of bearing of the countershaft is increased, and its liability to torsion diminished, and dirt and other foreign substances are kept out of the journal.

Seventh. The end of the box and countershaft are brought within the plane of the bevel-wheel, thus bringing the pressure to bear more directly upon them.

I deem it unnecessary to describe in detail here the construction of the driving-wheel, as it is fully described in another application for Letters-Patent of the United States filed simultaneously with this.

I am aware that a bevel-wheel and spurpinion have been used on the same end of the counter-shaft and within the plane of the driving-wheel, and do not broadly claim such device; but,

Having thus described the construction and operation of my improved gearing for harvesters, what I claim therein as new, and described my name.
