.SPECIFICATION forming part of Letters Patent No. 458,106, dated August 18, 1891.

Application filed March 24, 1891. Serial No. 386,271. (No model.)

To all whom it may concern:

Be it known that I, EDWIN H. HATCHER, a citizen of the United States, residing at Neodesha, in the county of lVilson and State of Kansas, have invented certain new and useful Improvements in Tricycles; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in certainnew and useful improvements in bicycles and tricycles, whereby by a novel and peculiar construc tion I obtain greatly-increased speed with the usual movement of the footpedals, causing the main drive-wheel of the bicycle or tricycle to revolve several times for each revolution of the pedal or drive-shaft.

My invention further consists in the peculiar construction and combination of parts of a new andimproved tricycle.

My invention will be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 is a vertical sectional view of my new and improved tricycle. Fig. 2 is a sectional view taken on the plane indicated by line 2 2 of 1. Fig. 3 is a sectional view taken on the plane indicated by line 3 3 of Fig. l. Fig 4 is a sectional view of a modification of my invention, showing the multi plying-gear arranged at one end of the wheelhub outside of the wheel proper. Fig. 5 isa side elevation of my new and improved tricycle.

The same letters and numerals of reference indicate corresponding partsin all the figures.

Referring to the several parts by their designatingletters and numerals, a indicates the pedal-shaft of my cycle, to the ends of which the pedals b are secured.

0 indicates the fork of the machine, one end of which is secured to the usual collar (1, in which that end of the pedal-shaft turns, while the other end of the fork is secured to a collar A, keyed on the outer end of a cylinder annular wheel D, which is secured to the inner side of the hub-casing E.

The cylindrical hub of mycycle-wheel is formed at its center with a circular hub-casing formed of two halves or sections E E, the inner meeting ends of these sections being either bolted, riveted, or keyed together, or they may be threaded and screwed together, as shown, while the outer circular ends E of the hub havethe inner ends of the wire spokes of the main wheel secured in them, as shown. This casing thus forms the hub of the wheel and at the same time completely incloses all the gearing of my cycle, thoroughly protecting it from dirt, dust, or injury of any kind.

The pedal-shaft Ct, at a point within the easing E E, is formed with anannular series of serrations a, and upon it at this point fits a lever-arm F, the openingf in the inner end of which is serrated to fit the serrations a of the axle. By this peculiar construction the pedal-arm F is firmly secu red against turning on the axle, and for further precaution it is keyed on by an ordinary key. The outer half of the lever-arm F is formed with a longitudinal slot F, the edges of which are preferably curved in crosssection, and in this slot fits and runs a roller or small wheel G. This roller is mounted on the outer part of a heavy pin G, which extends from that side of the large annular wheel 0 at thepoint shown. It will now be seen that in operation as the pedal-shaft is revolved it will revolve the arm F, and as the pin G of the large wheel 0 fits in the longitudinal slot F of the arm F the annular wheel 0 will be thusrevolvedon the eccentric disk 13, the disk B being held stationary by the cylinder A, secured to it and to the machine-fork, the anti-friction roller G on the outer end of the pin G sliding in and out in the longitudinal slot F of the lever-arm F as the wheel 0 revolves around the eccentric disk B. As the wheel 0 re meshing with the teeth of the small wheel D.

In Fig. at of the drawings I have shown the same driving-gear arranged at the outer 'end of the hub outside of the wheel proper. The hub is in this case a plain cylinder, and at one end is enlarged, as shown, to enable the wheel D to be secured to it, and the other parts of the gear are practically the same as in the construction before described, as will be seen.

From the foregoing description, taken in connection with the accompanying drawings, theconstruction, operation, and great advantages of my new and improved tricycle will be readily understood.

It will be seen that with my invention a slow and easy movement of the feet will give a high rate of speed, while the invention is comparatively simple and very strong and durable in its construction.

In Fig. 5 I have shown my new and improved tricycle, which consists, broadly, of two small wheels mounted in line with each other at the ends of a backbone which is curved into substantially a half-circle, and a large drivewheel mounted beneath the center of this curved backbone in line with the two small end wheels, and in the peculiar connection between the main fork of the machine-frame and the backbone. 6 indicates the rear curved section of the backbone, having a fork at its lower end, in which a small wheel 16 is mounted, and formed at its upper end with a tubular projection 5, as shown. In this tubular projection 5 is pivotally secured by the nuts 17 a pivot projection 15, formed on the upper end of the curved front section 4 of the backbone, the forward end of this section being pivoted in a projection 14, formed on the handle-jacket 7. 8 indicates the main upright fork, in which is mounted the large main wheel 19, which is thus brought beneath the center of the curved arch or'backbone, and a second fork 0 extends from the handlejacket 7 to the hub of the main wheel, as shown. The handle-bar 2 passes through the jacket 7 and has a fork at its lower end in which is mounted the small wheel 16. In a tubular projection 9 on the upper end of the main fork 8 is adjustably mounted the saddle-support 10, on which the spring-saddle S is in turn adjustably mounted, thus giving vertical adjustment as well as adjustment forward or rearward to the saddle. The upper end of the upright fork 8 is pivotally connected by a link 11 with the upper end of the pivot projection 15 of the front fork-section 4, thus giving a flexible or yielding connection between the fork and the backbone.

It will be seen that my new and improved tricycle can run freely and smoothly over all kinds of roads, as the backbone will balance on the large middle wheel 19 in running over uneven ground, the machine running then on either the middle and rear or middle and front wheels, as will be readily understood.

Having thus described my invention, what I claim, and desire to secure by LettersPatent, 1s-

1. In acycle, the combination of the pedalshaft, the arm F, keyed thereon and formed with the longitudinal slot F, the cylinder A encircling the pedal-shaft and secured at its outer end to the machine-fork, the eccentric disk 13, keyed on the inner end of the cylinder, the large wheel 0, revolving on the ec centric disk, having the annular flange C, formed with teeth on itsinner face, and having the projecting pivotpin G, the main wheel having the hub formed at its center with the casing composed of the two halves or sections E and E, and the smallwheel D, secured to the inner side of the hub-casing, sub stantially as set forth.

2. The combination, in a tricycle, of the curved backbone-section 6, having the fork at its lower end and formed with the tubular projection 5 at its upper end, the curved section 4:, having the pivot projection 15 at its upper end, and the retaining-nuts on the upper end of the same, the main fork 8, having the tubular projection 9 at its upper end, the link 11, connecting the upper end of the fork 8 with the fork projection 15, the seat-support secured adj ustably in the tubular projection 9, the fork c, the handlejacket 7, having the projection 14, the steering-bar passing through said jacket and having the fork at its lower end, the large drive-wheel mounted in the forks S and c, and the two small wheels mounted, respectively, in the forks of the section 6, and the steering-bar 2 in line with the main wheel 19, substantially as set forth.

In testimony whereof I afl'i it my signature in presence of two witnesses.

EDVIN H. HATCHER.
