HAN D-CAR.

SEEGIFICATION forming part of Letters Patent No. 716,524, dated December 23, 1902.

Application filed February 25, 1902. Serial No. 95,542. (No model.)

To au whom, t may concern:

Beit known that I, JAMES DONOVAN, a eit- Zen of the United States, .residing at Three Rivers, in the county of St. Joseph and State of Michigan, have invented certain new and useful Improvements in Hand-Cars, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to a walking-beam, and particularly to the pitman-pivot carried thereby; and the invention consists, essentially, in the novel means employed for securing the pivot to the beam, whereby it will I5 be effectively braced to resist the strains to which it is subjected in use.

The invention further consists in the peculiar construction, arrangement, and combination of the various parts of the beam, as

ao will be hereinafter described.

In the drawings, Figure 1 is a perspective View of my improved walking-beam, illustrating the means for securing the pivot thereto. Fig. 2 is a sectional plan View of the beam,

z5 and Fig. 3 is a side elevation thereof.

In the drawings thus briefly described, A and B designate two complementary metallic members, each bent to form inclined portions C, securing portions D and F, and a central 3o section E. The members described are com# bined in the mannerindicated in Figs. l and 2, the portions C forming the handle-sections for the beam and the sections E the body. The members are connected by rivets a and Z2, which extend through the securing portions D and F, respectively.

The handle-sections C are apertured at their free ends to receive the handles I. The beam-body is also provided with apertures c,

4o which extend laterally through the body sides midway of the ends, as shown. Thimbles J are provided for the body, which are formed from the material about the apertures, the material being struck out by suitable mechanism to form alining bearings for the ful- Crum-shaft II.

L designates the pitman-pivot, which, as shown, is supported beneath the beam in proximity to one of the body ends and is braced, as hereinafter set forth, to resist the strains to which it is subjected. I have shown the pivot as carried by a support M, secured at its upper end between the portions F by means of the rivets b. This support in turn is braced by an inclined section extending from the lower end of the support to the beam.

More particularly, the construction of the connecting mechanism is as follows: The` support and brace are formed, preferably, of two angle-shaped members P, the upper ends of the vertical portions of the members being con-nected to the beam in the manner described and bent so as to be spaced apart at the lower ends to carry the pivot. The inclined portions O of the members are connected at their upper ends to the fulcrumshaft K, and the ends of these members are preferably provided with thimbles Q, formed in the same manner as the thimbles J, before described. The pitman which engages the pivot being of ordinary construction and forming no part of the present invention is not shown or described.

From the construction of the walking-beam it will be obvious that by supporting and bracing the pitman-pivot in the manner set forth it vwill be readily enabled to withstand the strains to which it is necessarily subjected, and thus a rigid and durable beam structure is produced. It will also be noticed that the means employed for securing the pivot to the beam are of simple and durable construction, which permits the walking-beam to be manufactured at a minimum cost.

What I claim as my invention isl. A walking-beam comprisinga body, handle-sections therefor, a support depending from the beam in proximity to one of the body ends, the pivot carried by said support, and an inclined brace extending from the lower end of the support to the beam.

2. A Walking-beam comprisinga body, handie-sections therefor, the pitman-pivot suping the lower portion of said support with ported beneath the beam near one end of the the fulerum-shaft. .1o body, andra brace for the pivot-support.
