CENTERING DEVICE.

Specification of Letters Patent.

Patented Feb. 11,1913.

Application filed July 19, 1910. Serial No. 572,757.

To all whom it may concern Be it known that I, VICTOR WILLOUGHBY, residing at Jefi'ersonville, Indiana, and being a citizen of the United States, have invented certain new and useful Improvements in Centering Devices, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious thatvarious modiiications thereof will occur to persons skilled in the art,

In said drawings: Figure 1 is a longi tudinal sectional view taken on the plane indicated'by line l1 of Fig. 2. Fig. 2 is a longitudinal sectional view taken on a plane at right angles to the plane of the section shownin Fig. 1, and approximately on line 2-2 of said figure.

Referring to the drawings by numerals, 1 represents the draft sills which may comprise extension of the center sills, '2 the end sill, and 3 the draw bar, as in ordinary car construction. Occupying a position adjacent the inner face of the end sill, and between and supported by the draft sills, is the centering device for the draw bar 3, which centering device is the particular subject matter of the present invention.

To the under side of each of the draft sills is bolted or otherwise suitably secured a guide hanger 4, said hangers being identical in form and positioned directly opposite each other. A transversely disposed slidingly mounted casting 5 has its 'ends'extending through and sustained by hangers 4. At a point approximately midway in the length-of casting 5 the casting is formed with an upwardly extending arm 6, formed preferably of a central web and suitable stiffening flanges. Extending from one draft sill to the other, and passing loosely through a suitable aperture formed in the web of the arm 6 and through apertures in the said sills, is a bolt 7, which bolt is held in place by any suitable means, as by the usual nut retained by a pin or other locking means. 1

Disposed between the web of the arm 6 and one of the draft sills, and surrounding the bolt 7, is a coil spring 8. Disposed between the web of the arm 6, and the other of the draft sills, and surrounding the bolt 7, is a similar coil spring 8.' The springs 8 and 8 are of equal length and tension so as normally to hold the arm 6 in a position approximately midway between the draft sills. Stifl'ening angle bars 9 are applied to the opposite faces of the center sills, and bolt 7 is passed through the vertical flanges of the angle bars.

Formed integral with the under. face of the casting 5 is a pair of depending arms 10,

said arms being spaced apart and carr ng,

between their lower ends a. roller 11, w ich roller is journaled upon a bolt 12 extend.- ing through the lower ends of arms 10. The arms 10 are disposed beneath the arm 6 and midway in the length of thelcasting 5 sutlicient space being left between each 0 the said arms and its adjacent hanger 4 for permitting requisite movement of the casting 5 in said guide hangers.

Thedraw bar 3 extends between the arms 10 and rests upon the roller 11, said arms 10 with the roller ll and bolt 12 thus serving as a draw bar carrying iron. Any side'wise movement of the draw bar 3 will shift casting 5 longitudinally through hangers 4,

compressing one or the other of the springs 8 or 8. When lateral pressure is relieved from the draw bar, expanding movement of the compressed spring will return thedraw bar to its normal, central position.

What I claim is:

1. In a device of the class described, a

pair of supporting members, a draw bar,

draw bar supporting casting transversely movably supported by said supporting members, a pair of pendent lugs formed integral with sald casting, an anti-friction roller between said lugs adapted to receive said draw bar, an upstanding arm formed integral with said casting and projecting between said supporting members, and a pair of compression springs extendingbetween opposite side portions of said upstanding arm and said supporting members 'for maintaining proper relative position of said draw bar.

2. In a device of the class described, a slidable casting having a pair of depending sills and a slidable easting supported from said hangers and bolt. 1 In itness whereof I have hereunte set my hand in the presence of two witnesses.

VICTOR WILLOUGHBY.

roller supporting arms and a vertical stop arm projecting from the top of said bar .and in a plane intermediate the plane containing said depending arms.

3. In a device of the class despribed, a

pair of sills, angle irOns stiffening each of \Vitnesses: I said sills,a boltv passing through'said sills I .Jorm J. SNYDER, and angle-iron, hangersdepending from said J H. BALDW N. I
