CHARLES T. SCHOEN, OF PHILADELPHIA, PENNSYLVANIA.

BOLSTER GUIDE-BAR FOR CAR-TRUCKS.

SPECIFICATION forming part of Letters Patent No. 437,722, dated October '7, 1890.

Application led J' annary 24, 1890. Serial No.337,980. (No model.)

To all whom it may concern:

Be it known that I, CHARLES T. SoHoEN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Bolster Guide-Bars and Bolster-Guide-Bar Plates, of which the followingr is a full, clear, and exact description.

The object of this invention is to produce, from pressed steel especially, a bolster guidebar and a bolster-guide-bar plate for railwaycar trucks.

The invention consists of a bolster guidebar and a bolster-guide-bar plate constructed, by preference, of pressed steel, substantially in the manner hereinafter more particularly set forth and linally claimed.

In the accompanying drawings, illustrating myinvention, in the several figures of which like parts are similarly designated, Figure l is a front elevation, Fig. 2 a side elevation, Fig. 3 a top plan view, Fig. 4 a bottom plan View, and Fig. 5 a cross-section taken in the plane of line fr, Fig. 1, of the bolster guidebar. Fig. 6 is an elevation, and Fig. 7 a longitudinal section, of the bolsterguide-bar plate; and Fig. 8 is a perspective view of portions of a railway-car truck in outline with my guide-bar and plate applied. Fig. 9 is a perspective view of a modified form of guide- The bolster guide-bar a is struck up in dies or by other suitable devices and from sheet or plate steel or other Wrought metal which maybe foundin open market, or may be made in shape to order. In order to obtain the requisite strength, this guide-bar is bellied centrally, as at b, and, preferably, in the arcs of circles, as indicated in the sectional view, Fig. 5. The ends c may be squared and turned in to form heads, as at CZ and e, and these heads are provided with openings f and g, respectively, for the passage of a throughbolt h, (shown in dotted lines in Fig. 8,) for connecting the parts with the braces or beams of the truck. Side Wings i' are provided for co-operation with the bolster guide-plates. (Shown in Figs. 6, 7, and 8, and hereinafter more particularly described.) The Wings i' are enlarged at their lower ends to form liangesj, which are provided With bolt-holes to receive the bolts 7c, (see Fig. 8,) by means of which the bolster guide-bar is secured to the truck.

The bolster-guide-bar plate Z (see Figs. 6,

7, and S) has struck up the parallel ribs m, which form Ways to receive the Wings i of the bolster guide-bar and to guide the parts in the movement of the truck. Holes n are made in the guide-bar plate for the reception of fastening devices to secure the guide-bar plate to the truck.

The parts are assembled as clearly indicated in Fig. 8. Very obviously modiications in the form of these parts will be made to suit the requirements of railway construction, and these I esteem as within my invention so far as they contain the principle of my invention.

These wrought-ni etal bolster guide-bars and bolster-guide-bar plates will be constructed so that they may be interchangeable with the cast-metal and other bolster guide-bars and guide-bar platesin common use, so that in repairing cars old bolts and old bolt-holes may be employed in assembling my improved bars and plates. Another and manifest advantage of my invention is the great difference in weight iu favor of my construction without any impairment of strength or durability, but rather in gain of both.

In the use of the term bellied, as applied to the longitudinal elevation of the bolster guide-bar, I mean to include any form or extent of elevation of the metal which will strengthen the guide-bar. For example, the bellying may be angular, as indicated in Fig. 9, instead of curvilinear, and it may be in a single straight line instead of at inclinations.

What I claim isl. A pressed-steel or other Wrought-metal bolster guide-bar having edge fianges for attachment to a part of the truck, bellied longitudinally and having terminal heads for the reception of the connecting-bolt,'and also having wings for (3o-operation with a bolsterguide-bar plate, substantially as and for the purpose described.

2. A bolster guide-bar provided with basetlanges, Wings, and an intermediate bellied portion of curvilinear outline and terminating in squared end portions or heads and constructed of pressed steel or other Wrought metal, substantially as described.

In testimony whereof I have hereunto set my hand this 23d day of January, A. D. 1890.

CHARLES T. SCHOEN.
