CARRIAGE.

SPECIFICATION forming part of Letters Patent No. 765,983, dated July 26, 1904.

Application filed March 21, 1904.

To all whom, it may concern.-

Be it known that I, VVILLIAH B. MORGEY, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Carriages, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

The objectof my invention is to so reconstruct the ordinary carriage of the perchmount type that the shafts may be swung upward to a substantially vertical position and that the front portions of the shafts will be relieved from the strain incident to mounting the vehicle-body from steps secured to such shafts. v

The ordinary carriage of the type specified is open to a serious objection arising from the location of the steps on the shafts. VVhenever the driver mounts the carriage, a severe strain is thrown upon the shafts, which strain is imparted to the horse or horses hitched thereto. In all but the lighter draft vehicles this cannot conveniently be remedied by locating the step in any other situation. In my invention the step is retained in its old position; but the construction of the shaft itself is so changed and such additional mechanism is provided that the strain is properly distributed on the vehicle-gear. Another objection to the ordinary carriage is that the shafts are at their rear ends necessarily curved downwardly to enable them to be hinged to the axle, and the vehicle-body overhangs the front of the axle, which features of construction make it impossible to elevate the shafts to a vertical position or any position approaching a vertical position. This objection also is remedied by my improved construction. Another objection to the ordinary carriage is that as the pulling strain is wholly on the axle and as the axle is below the direct'line of draft the tendency is to pull the king-bolt and fifth-wheel forwardly, while any weight thrown on the shafts, as in mounting the vehicle, tends to pull the king-bolt and fifthwheel backwardly. Thus these parts are constantly subjected to opposing twisting strains,

which wear them out. My improved construction also entirely removes this objection.

1n the drawings, Figure 1 is a plan view of a portion of a carriage embodying my invention. vFig. 2 is a section on the line 2 2 of Fig. 1.

a is the fore axle; (Z, the king-bolt; e, the fifth-wheel; f, the lower half of the elliptical or double leaf-spring on which the carriagebody is mounted; a, the perch or reach joining the fore and hind axles, and r the headblock of the perch, to which the lower half f of the spring is secured in the usual manner.

The shafts are of the usual shapethat is, substantially straight except at their rear ends, where they are curved downwardly toward the axle. The construction of the shafts, however, differs from that usually adopted in that they are each made in two sections, the relatively short downwardly-curved rear section I; and the relatively long substantially straight,

front section 0. The two sections are hinged or pivoted together at g, and the rear section is pivotally attached in the usual manner of shafts to the fore axle. The rear sections Z) Z) of the shafts are connected at their front ends by the cross-bar t', and the cross-bar 2' is connected to a'bolt p by means of bars 3' j, the front ends of which are secured, some distance apart from each other, to the cross-bar 2', while the converging rear ends are integral with a collar on a-bolt 0. To accommodate thiscollar, the bolt 19 may be welded or otherwise integrally secured to the spring-stay 0, secured to the perch n, it being undesirable to extend the king-bolt up through the spring in View of the weakening of the spring that would result therefrom.

The steps on m are secured to the sections 5 Z) of the shaft. In mounting the wagon the entire weight of the driver as he places his foot upon the step is thrown upon the rear sections 6 b of the shafts and their supportingframe t' j], and no weight is thrown upon the front sections 0 0 of the shafts, and thus none upon the horses. The frame 7' has sufficient resiliency to cause the sections 6 b to have an appreciable pivotal movement upon the axle to which they are hinged.

In hitching or unhitching the front sections 0 c of the shafts are alone manipulated. As the hinges g are forward of the wagon-body and not underneath it, as usual, and as the sections 0 c are substantially straight, they can be lifted to a vertical position without interfer ence with the front of the wagon-body.

To prevent the bolt being twisted by the weight or strain thus thrown upon it, a stay Z is secured at one end to the perch 77., while the other end embraces the top of the bolt 39 and abuts against the collar Zr.

it is the usual cross-bar, to which the whiflietree is attached. This cross-bar connects the rear ends of the front sections 0 c of the shafts,

By the foregoing principle of construction it will be observed that the bolt or pin p, to which the bars ,y'j are attached, is secured to the spring-stay, which while resting on the spring supported on the head-block of the perch is also secured to the porch back of the head-block, and it will also be observed that the stay Z is secured to the perch. Thus it will be seen that any strain on the cross-bar c and bars y' is thrown on the perch and is not borne by the axle.

In the ordinary construction or, in fact, any construction in which the shafts are secured wholly to the axle,whethcr directly or through the medium of an intermediate frame, the pulling strain being thrown entirely on the axle, and therefore at a point below the direct line of draft, tends to pull the king-bolt and fifthwheel forwardly, while stepping on the shafts tends to pull the bolt and fifth-wheel backwardly. Thus these parts are subjected to great wear and tear and torsional strain, necessitating their frequent repair and replacement. By my construction the strain on the frame if y' is thrown on the top of the bolt f, which is in the direct line of draft back of the front sections of the shaft, and this strain in turn is thrown on the perch, which is the member of the wagon-gear best able to bear it.

The specific construction described is suitable for heavy-draft wagons. For lighter-d raft vehicles, such as buggies, it is customary to secure the steps to the buggy-body, and in these vehicles especially it is not essential that the sections 7) 6 should be hinged to the axle, but they may be rigidly secured thereto. hen the sections 0 6 are rigidly secured to the axle and the steps secured to the vehicle-body, the connection between the shafts and bolt 1) need not be so stout, and a single bar j may connect the cross-bar t' with said bolt.

Other variations from the foregoing specific structure may be made without departing from the invention, such variations depending upon the fancy of the individual constructor as well as upon the different kinds of vehicles to which the invention is applied.

The invention is applicable to wagons in which a pole is used as well as to those in which shafts are used. In this type of wagon the shaft-sections M are retained and the pole pivoted or hinged to the cross-bar a: midway of the latters length.

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is-- 1.
