SAMUEL TOOMEY, OF CANAL DOVER, OHIO.

AXLE FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 346,001, dated July 20, 1886.

(No model.)

To all whom t may concern:

Be it known that I, SAMUEL TooMEY, of Canal Dover, in the county of Tuscarawas and State of Ohio, have invented an Improved Axle for Vehicles; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part oi' this specication.

My invention consists in abent axle formed solid in its middle raised portion and of skeleton, open, trussed construction at the bent or curved portions, substantially as hereinafter specified, also, in the specific improvements hereinafter set forth.

In the annexed drawings, Figure l represents a side view of a vehicle axle construct ed according to my improvements; Fig. 2, a top view ot the same, Fig. 3, a cross-section of the solid part in a plane indicated by the line I l, Fig. I, Fig. 4, a cross-section of the trussed part in a plane indicated by the line 2 2, Fig. I; Fig. 5, a side view or" one of the improved axles modified in construction.

Like letters designate corresponding parts in all of the figures.

The drawings represent a sulky-axle to which the improved construction is well adapted; but the invention is applicable to bent axles for other kinds ot' vehicles.

It being desirable to make the axles as light as practicable, and at the same time sufficiently strong and rigid, as well as cheap, I construct the middle part, A, solid and of wood. This part of the axle is made comparatively high and thin; and to give it greater rigidity with the utmost lightness, the sides are tluted in the middle, as shown fully in Fig. 3, making the crossvsection approximately of the form ofthe numeral 8.

I prefer to make the whole axle of one piece of wood, and to that end I form the bent trussed parts B B each of two thin strips, c b. continuations respectively from the upper and lower parts of the solid portion A. These strips are bent separately and trussed together when thus bent by tubular washers or spools c c, placed endwise between the strips and bolts d d, as shown in Fig. 4, or by clips, as shown at e, Figs. l and 2.

As a modification of the above-described construction, but not considered as good as that, I show the bent strips c Z) made of separate parts from the middle solid portion, A,

and secured at the inner ends to the said middle portion by clips or bolts, as shown in Fig. 5, clips being shown at one end and bolts at the other end. In this modified construction the bent strips a b may be either of wood or of thin strips of metal, preferably steel.

The bent strips (t b are strongly secured to the spindles O O of the axles by clipsff, as shown. v

In the use of raised axles, as for sulkies, where the horse travels close back to the body of the vehicle, it is desirable to give as great width of space as possible under -the raised part ot' the axle, in order that sufficient 1ateral room be given to the animal to travel without striking his hooks against the bent or end parts thereof. This is especially necessary for trotting-horses. I Itherefore form the bent or upright portions of the front axle as close to the wheels as practicable, as indicated in the drawings, and render these bent portions as upright or near a perpendicular position as may be. This Aconstruction does not allow room for the ordinary leather step on the axle. To obviate this ditliculty, I form on one of the clips ff, by which the adjacent spindle is secured to the axle, a small raised step, D, as shown in Figs. land 2. This need not be broad, and sutlicient room is allowed for this construction of a step.

In Letters Patent No. 294,528, granted t-o me March 4, 1884, I have described and claimed a bent carriage-axle trussed throughout its length between its spindles. I disclaim such an axle in the present case.

I claim as my inventionl. A bent axle formed solid in its middle raised portion, and in its bent portions with separate strips trussed together, substantially as and for the purpose set forth.

2. A bent axle formed o f a single piece of wood, solid in its middle portion and formed in separate strips in its bent portions, continuations oi' the middle solid portion,and trussed together, substantially as and for the purpose herein specified.

3. A bent axle formed solid in the middle and tinted at the sides, asset forth, and trussed at the ends, as herein specified.
