TWO-VVHEELED VEl-llCLE.

QFEGIEICATIQN forming part of Letters Patent No. 329,124, dated October 2 1 Application filed December 26,1884. Serial No. 151,257. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN-O. BLOOHER, a citizen of the United States, residing at Lima, in the county of Allen and State of Ohio, have invented certain new and useful Improvements 1n TwoVVheeled Vehicles; and I do declare the following to be a fullfclcar, 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, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specifica tion.

My invention relates to improvements in two-wheeled vehicles.

In my invention the body of the cart is suspended in such manner as to take off or to new tralize the horse 1not-ion,and to prevent shocks from uneven roads or from obstacles over which the wheels may pass from being roughly communicated to the body of the vehicle. This I accomplish by suspending the front and rear ends in such a way that the movements to which the vehicle is thus subjected are either neutralized or converted into easy pliant counter movements of the body not unpleasant to the occupants.

Figure l is a perspective View of a twowheeled vehicle, commonly termed a roadcart, having my improvements embodied therein. Fig. 2 is a side elevation of the same, the dotted lines in this figure showing the up and down movements of the body and its attachments in dotted lines. Fig. 3 is a top view of one side of the same with the seat removed, and shows a longitudinal, transverse, and partially rotary movement of the body, also in dotted lines. Fig. 4 is a bottom view of the same, with dotted lines showing the comparative movement of the front and rear of the body laterally. Fig. 5 is a perspective view of the two sections of the hangers, the fastening-loop being shown on one section.

A is the body of the cart, which is of the usual constructiomwith an open front frame extending forward of the seat B. On the under side of the frame,at the front end,are angular bars a 0. These are bent at an angle in the middle, which latter part projects downward from the frame, and a block, 0, is inserted in the angle between the iron and the frame, and

a bolt secures the angle-iron, block, and frame together. This bolt also secures the end of a strap of flexible material, (Z, to the iron at this point to allow free play of the front end of the body in any direction. A chain or one or more links may be substituted for the strap, as it is only necessary that the points of flexure be at or near the attached ends. The front ends of the straps d are attachcd,by preference, to the cross-bar d of the shafts or thills c. The rear end of the body is suspended from the ends of the long cyma-reversa springs e c,which latter are fastened upon the tops of the thills and extend upward and backward in a curve.

At their rear ends,which curve downward, a little beyond the rear end of the body, are flexibly attached the long links or hangers f f. These hangers extend forward from their points of attachment (to the springs e c) as well as downward, and are connected at the lower ends with the transverse semi-elliptic spring 9. Upon the spring-bar of this spring rest the bearingirons h h of the rear end of the body.

By reference to Fig. 2 it will be seen that the line of the linksff and the line of compression of the spring 9 is at an angle of about forty degrees from a perpendicular. The movements of the springs are therefore oblique instead of vertical, and in the direction of the line seen drawn from the point of resistance t to the points of suspension at the rear ends of the springs e c. This manner of suspending the body A is essential to the movements here inafter described, and which latter are termed counter-movements and serve to counteract the usual sudden shocks to which vehicles of this character are subjected, as before mentioned. It also allows the additional weight of more than one person upon the seat Without materially disturbing the equipoise of the body. At the front end the body is allowed free up-and-down and lateral play; but its movements are more limited than at the rear end, which is suspended from the long pendent links f f, and the up-and-down motion by the horse is virtually cou nteraeted by the clasticity of the suspending members, springs e e, and the transverse spring The latter, being suspended from the former by the linksff, allows the pendulous body to gyrate around the pivotal points of suspension, as well as to move in any direction at any angle thereto, thereby breaking up the single movement caused by a sudden shock into a number of easy, pliant counter-movements, which latter 5 are comparatively little felt and not at all unpleasant. By reference to Fig-2 it will be noticed that the linksff and the line of compression of spring 9 arein direct line with the point of resistance 13 of the right wheel 0, so

that when the spring 9 and the side springs, e e,first take up the shock the body A (being weighted) descends at the rear from the yielding of the springs, and the flexible straps 'd d allow the front end to be thrown upward, as

15 seen in dotted lines. In addition to these movements,it is thrown sidewise and obliquely backward and toward the left, as seen in Fig.

3, and in recovering its normal position it is carried by the hangers f f, both obliquely and circuitously forward and toward the right orv opposite side again, as seen in the dotted lines, Fig. .4. Each movement changing its direction is less than the one preceding it, so that the force first exerted upon the body is soon 2 lost or neutralized in the succeeding and successively lessening counter-movements. One of the linksf is shown enlarged in the detail, Fig." 5, and consists of the two sections 76 and 70. These pieces are flat and overlap each 0 other. The piece It is provided with holes ZZZ foradj ustrnent,with which thepinm,projecting at right angles from the innerside of section k,engages. A loose loop, a, slides down over the lapped parts and securely clamps the two 5 sections together.

I claim as my invention--- l. The body of a road-cart, having its rear end swung freely from the ends of the long body to move about the points of suspension,

as set forth. I 2. The combination,with the body ofa roadcart,suspended by flexible straps at the front end, of the long cyma-reversa side springs,

.the pendent links connected therewith, and

the transverse spring swung from the ends of 0 the latter, substantially as and for the purpose set forth.

3. In combination with the body ofa roadcart, the long cyma-reversa springs extending rearward and upward from the shafts, the pendulous links suspended from said springs, the semi-elliptic transverse spring, the springbar and bearing-irons, and the flexible hangers connecting the front end of said body with the crossbar of the shafts, substantially as and for the purposehereinbefore set forth.

4. In a roadcart, the S-shaped or cy1na-re versa springs, the pendulous links flexibly attached thereto, and the semi-elliptic spring supporting the rear of the body, a line drawn through said links and the line of compression of said semi-elliptic spring cutting the points of resistance of the wheels, substantially as set forth. i

In testimony whereof I aiflx my signature in presence of two witnesses.

JOHN G. BLOCHER.
