TWO-WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 492,224, dated February 21, 1893.

Application iiled August 3, 1891. Renewed November 26, 1892. Serial No. 453,212. (No model.)

To all whom it may concern.'

Be it known that I, EvERETi` F. MORSE, a citizen of the United States, residing at Tru.-V mansburg, in the county of Tompkins and State of New York,have invented certain new and useful Improvements in Two-Wheeled Vehicles, of which the following is a specilication.

The objects of my invention are to provide an elastic connection between the body and gear which will permit the free ends of the thills to vibrate up and down independently of the body and also form a yielding resistance to this vibratory movement that will increase in intensity as the load in the vehicle is increased and the body depressed, and to provide convenient means for adjusting the body to horses of different heights, also to provide means for increasing the resistance to sidewise tipping of the body independent of the resistance to vertical depression. I attain these objects by the mechanism illustrated in the accompanying drawings in Which,-

Figure 1, is a side elevation of a part of a vehicle embodying my improvements and having parts of one thill and the body broken away to more fully show the details of construction. Fig. 2, is a bottom View of the same.

Similar letters refer to similar parts throughout both the views.

Referring to the drawings, G is the axle.

A A, are the thills securely attached to the axle.

H and B are cross bars connecting the thills.

C is the body mounted on elliptic springs c c, arranged lengthwise of the gear and on either side of the body. These springs have their lower halves hinged to the gear and their upper halves rigidly attached to the body, thus permitting the body to tip endwise freely except as restrained by arm b, which extends in a nearly vertical direction to a point directly or obliquely below the axis m, about which the body rocks endwise. Bar g, extends crosswise of the body and has its ends securely bolted to the framework of the same. To this, arm b, is securely attached.

Eyes may be turned on both the upper and lower ends of arm b, for the purpose of connecting it to bracket z', and brace a, respectively. Step arms D, have their upper ends lsecurely bolted to the thills and are provided with lug bolts p p, projecting from them crosswise ot' the cart. The triangular brace a a', has its forward ends provided with eyes adapted to receive the lug bolts p p, to which it is secured. The rear end of the brace is also provided with eyes through which and the lower end of arm b, a bolt passes. Thus arranged, the lower end of arm b, is permitted to move up and down with the body by the angular motion of brace a, about the lug bolts p p, at the same time it is restrained to follow the path b b2, in this movement. The triangular form of the brace a a', restrains the end of arm b, from moving laterally and thereby provides an additional restraint to the sidewise tipping of the body. Bracket z', which is securely bolted to the bottom of the seat, is provided with a curved slot which follows the path of the upper end of arm b, as it is turned in a vert-ical longitudinal plane about its attachment to bar g. Bolt h adapted to extend through the slot and the upper eye of arm b, is provided with a head on one end and a nut h, with handle on the other. By screwing up the uut h, the arm b, is firmly clamped to the bracket t', and by loosening this bolt, arm b, can move along the slot in bracket t', and the body can be tipped endwise so as to be level, with the thills attached to a horse of any height, and when adjusted to the desired position, is securely held by tightening the bolt h.

In operation, the yielding of the supporting springs c, as the load is increased, permits the body to be depressed carrying the arm b, down with it. If the body is tipped endwise, the lower end of arm b, tends to follow a path circular about the axis m, of 'tipping but it is restrained from following this path by the brace a, so that the body can tip endwise only through the ilexion of arm b. When the body is in its normal position, the arm b, acts with the lever arm m b to resist the tipping of the body, but when the body is depressed so that the lower end occupies the position h2, the arm b, then acts with the much longer lever arm m b2, to resist the tipping of the body. Thus by this arrangement the resistance to the endwise tipping of the body IOO body and accomplish substantially the samev obj ects.

Instead of hinge d, a iiexion connection with the gear can be used or a rigid connection which would ntilizethe resistance of the.V

springs to permit the endwise rocking of the body, as it lisy ,only `necessary that the axis about which the bodyrocks should be above thel end bf, ofarm b, so-thatitshall move away fromthis axis as the body is depressed.J It is also apparentthatthethills may be iiexibly connected to the axle orliinged to thel same instead of makingthe joint directly between thespring and axle.

Whilearm lb,-is.shown.to be connected to the body in a manner permitting-.the body to be adj ustedto horses of different heights, it is evident that thisA arm may beV attached to thebodyin any secure manner and perform its principal'function, also, thatthe arm b,
