RUNNING-GEAR FOR TRACTION-ENGINES AND TENDERS.

SPECIFICATION forming part of Letters Patent No. 711,330, dated October 14, 1902.

Application filed May 26,1902. Serial No. 109,052. (No mania 1'0 all whom, it may concern:

Be it known that we, CHARLES S. MILLER and EBER C. AUSTIN, citizens of the United States, residing at Hampton, in the county of Hamilton and State of Nebraska, have invented certain new and useful Improvements in Running-Gear for Traction-Engines and Tenders; and we do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The purpose of this invention is the provision of a novel form of gearing for the tender of a traction-engine which will admit of the machine turning in a small space and at the same time preserve the alinement of the engine and the tender, this being a desideratum in order to prevent cramping or binding between the framework of the engine proper and tender when making a turn.

In accordance with this invention the tender is mounted upon stub-axles firmly braced and having connection with the front axle of the engine, so as to turn simultaneously therewith in an opposite direction, whereby the tender moves in an opposite direction to the engine in order to preserve the alinement.

The improvement consists, essentially, of the structural details, novel features, and peculiar combinations of the parts which hereinafter will be more particularly set forth, illustrated, and finally claimed.

In the drawings hereto attached and forming a part of the specification, Figure 1 is a plan view of the running-gear of a tractionengine and its tender, embodying the essential features of the invention. Fig. 2 is a side view thereof, the body of the engine and tender and the axles and wheels of the traction-engine being omitted. Fig. 3 is a view similar to Fig. 1, showingthe position ofthe parts when the front axle of the engine is turned. Fig. 4 is a transverse section about on the line X X of Fig. 1 looking toward the front, the right-hand axle being in section.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

any type and is mounted upon axles l and 2, constituting parts of the running-gear. The rear axle 2 is fixed, whereas the front axle 1 is mounted to turn about a vertical axis in order to admit of turning and properly securing the engine when in motion.

The invention resides more particularly in the peculiar formation of the running-gear for the tender, and said running-gear comprises a pole or tongue 3 and a transverse bar 4, rigidly connected intermediate of its ends with the pole 3 and strengthened by means of oppositely-inclined braces 5, secured intermediate of their ends to the outer portions of the transverse bar 4 and having connection with the pole 3 a distance from said bar. A second transverse bar 6 is connected midway of its ends to the front portion of the pole 3, and stay-bars 7 are connected near theirfront ends to the outer ends of the transverse bar 6 in any substantial way and have their rear ends converged and rigidly attached to the braces 5 in advance of the transverse bar 4. Braces 8 have their front ends attached to ,the stay-bars 7 a short distance in the rear of the transverse bar 6 and are rearwardly converged and attached to opposite sides of the pole or tongue 3. In the preferable construction the braces 8 form parts of the same bar as the oppositely-inclined braces 5. The stay-bars 7 are extended in front of the transverse bar 6 for convenience of attachment of the tender to the framework of the traction-engine. A transverse bar is arranged above the bar 4, in the plane thereof, and comprises the centrallydepressed portion 9 and the elevated end portions 10, the tank 11 being fitted in the depressed part 9 of said bar and riveted or otherwise secured thereto. An arched bar 12 supports the central portion 9 of the bar, and its downwardly-diverged portions are secured to the middle portion of the transverse bar 4, as shown most clearly in Fig. 4. Knees 13 connect the ends 10 of the upper transverse bar with the side portions of the tank 11 and brace the same, as well as staying the outer ends of the said upper transverse bar. Stub-axles 14 are pivotally connected intermediate of their ends to the outer end portions of the upper and lower transverse bars by means of king-bolts or analogous means. The spindles or axlearms of the parts-14 project beyond the ends of the transverse bars and receive the ground: wheels 16. Braces 17 are interposed between the top side of the axles 14 and the end portions 10 of the upper transverse bar and have their end portions secured to the said axles. The outer end portions of the braces 17 are bent into an approximately U form and fit snugly between the parts 14 and 10, as shown most clearly in Fig. 4. The U-shaped ends of the braces 17 have their upper and lower members apertured to receive the king-bolts or pivotfastenings 15. The inner ends of the stubaxles are notched or mortised to receive the overlapped ends of the elbow-shaped links 18, which extend in opposite directions from the respective stub-axles. Transverse swing-bars 19 and 20 are pivoted intermediate of their ends to the pole or tongue 3 and are locatedthe one in front of and the other in the rear of the stub-axles and the transverse bars, to which said stub-axles are pivoted. The front set of links 18 are pivotally connected to the swing-bar l9, and the rear set have a like connection with the swing-bar 20. Rods 21 connect the swing-bar 19 with the front axle 1, and any turning of said axle causes the swingbars 19 and 20 to correspondingly turn. By having the inner ends of the stub-axles connected by links with the swing-bars 19 and 20 said stub-axles swing in an inverse direction to the axle 1, as shown most clearly in Fig. 3, thereby causing the tender to move in an opposite direction to the traction-engine when making a turn, with the result that the alinement of the traction-engine and tender is preserved. As shown in Fig. 3, when the axle 1 is turned to cause the engine to move to the right the stub-axles 14 are turned to cause the tender to move to the left, thereby enabling the engine and tender to turn in a comparatively small space and at the same time preserve their alinement, which is essential, as herein stated.

Having thus described the invention, what is claimed as new is 1. In combination, upper and lower transverse bars, the upper bar having its central portion depressed, an arched brace between the middle portions of the saidtransverse bars, stub-axles pivoted between the outer ends of the said bars, braces between the stub-axles and one of the said transverse bars, a tank seated in the depression of the upper transverse bar, knees between 'the sides of the tank and the ends of the upper bar, and means for connecting the inner ends of the stub-axles, substantially as set forth.

2. In combination, a pole or tongue, front and rear transverse bars connected intermediate of their ends to the said pole, oppositelyinclined braces between the said pole and rear transverse bar, stay-bars connecting the ends of the front transverse bar with the said oppositely-inclined braces, and other braces attached to the stay-bars near their front ends and rearwardly converged and attached to the said pole or tongue, substantially as set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
