TIMOTHY DOLAND, OF WVELLINGTON, OHIO.

CARRlAGE-GEARING.

SPECIFICATION forming part of Letters Patent No. 469,735, dated March 1, 1892.

Application filed October 14, 1891. $erial No. 408,676. (No model.)

.To all whom it may concern:

Be'it known that I, TIMOTHY DOLAND, a citizen of the United States, residing at WVellington, in the county of Lorain and State of Ohio, have invented certain new Improvements in Carriage-Gearing, of which thefollowing is a full, clear, and complete description.

The nature of ,my invention relates to the arrangement of two spring-braces, in connection with the springs, spring-bar, and axles of the carriage, said spring-braces being attached as hereinafter fully shown, and crossing each other near the front axle, forming a device which does away with the ordinary fifth-wheel and forming a lighter and stronger gearing than the usual form of carriage-gear- 1ng.

That the invention may be fully seen and understood, reference will be had to the following specification and annexed drawings, forming part thereof.

Figure 1 is a View of the under side of the gearing of a carriage with the improved attachment shown thereon. Fig. 2 is a front end view thereof; Fig. 3, a side View; and Fig. 4 is a cross-section on line a: 00, Figs. 1 and 2.

Like letters of reference designate like parts in the drawings and specification.

The spring-braces A A are clipped to the rear axle at the points a a, near the hubs of the wheels, and extend forward diagonally, as shown in Fig. 1, crossing each other at b, and being bolted to the side springs B B at their point of intersection c c therewith.

The spring-braces A A extend forward of their point of intersection b, and are bolted to the spring-bar O at old, their forward terminals being curved, as shown in Fig. 1, and forming a substitute for a fifth-wheel, answering all the purposes of the ordinary fifth-wheel or circle now used, and at the same time enhancing the value of the gear in strength, lightness, neatness, and utility.

In case the axle is provided with axlestock e, which is clipped thereto, a piece of steel or iron 6' is secured to the top of the stock. This iron 6 is called friction-plate, being interposed between the axle and the curved ends of the spring-braces A A. In case the axle is entirely of iron or steel the friction-plate is not necessary, as the braces will then be in direct contact with the body of the axle. The king-bolt '5 passes down through the spring-bar, axle-stock, frictionplate, and axle, as shown in Figs. 2, 3, and 4, having a nut on the under side thereof.

A safety-guard D, Figs. 1, 2, 8, and i, is used in connection with my improved gearing. The guard D is bolted to the spring-braces A A at their point of intersection 19, passing around under the axle A and is fastened to the spring-bar O at f by means of screw-bolts passing through the T-head and said springbar 0, Fig. 2. By this arrangement, as hereinbefore stated, the carriage-gearing is much lighter and stronger than in the usual form of construction, as the spring-braces A A extend diagonally from and across the central line of draft to the rear axle at a point near the wheel, thus forming braces and avoiding the lateral motion usual to the side-spring form of construction.

The ordinary circle or fifth-Wheel referred to as now used soon becomes loose and rattles. This is avoided in my improvement by the firm, simple, and peculiar construction, attachments, and arrangement.

The diagonal spring-braces A A consist, preferably, of one or more steel plates or leaves fastened to the side springs B B at c c, Fig. 1, on the under side thereof, thus supporting the body of the carriage upon four springs by means of the attachment of the side springs B B to the ties or body-rests E E with clips or bolts at any suitable point.

What I claim, and desire to secure by Let ters Patent, is

1. In a carriage gearing, the diagonal spring-braces A A, clipped to the rear axle near the wheels, crossing each other at 1), near the forward axle, the extended portions curved and rigidly secured to the spring-bar O, in combination with the side springs B B and the safety-guard D, substantially in the manner as set forth.

2. In a carriage-gearing, the safety-guard D, in combination with the spring-bar C and diagonal spring-braces A A, said guard being bolted to said braces at their intersectionpoint I), passing under the axle, and bolted to the front of the spring-bar, substantially as and for the purpose specified.

3. A carriage-gear formed by the diagonal In testimony whereof I aifix my signature in spring-braces A A, attached, as specified, to presence of witnesses. the rear axle, crossing each other at the point I), the forward terminals curved and bolted to FIMOTHY DOLAND' 5 the spring-bar, and the king-bolt passing down Witnesses:
