HARRY T. KRAKAU, OF CLEVELAND, OHIO, ASSIGNOR TO THE NATIONALMALLEABLE n CASTING-S COMPANY.
PIVOTAL CONNECTION FOB LOCOMOTIVES OF THE MALLET ARTICULATED'TYPE.
To all whom it may concern Be it known that I, HARRY T. KRAKAU, a citizen of the United States, and residing at Cleveland, Cuyahoga county, Ohio, have invented an Improvement in Pivotal Conmotions for Locomotives of the Mallet Articulated Type, of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 is a bottom plan view showing my improved connection as applied to two engines of a Mallet articulatedlocomotive;
Fig. 2 is an enlarged bottom plan view of the connection part-1y broken away; Fig. 3 is an elevation of the connection partly in section; Figs. 4, 5 and 6 are diagrammatic views of thetwo engines of a locomotive illustrating various conditions met in service; Fig. 1 showing the locomotive passing around a continuous curve; Fig. 5 showing the locomotive passing from a tangent to a curve, and Fig. 6 showing the locomotive having its two engines passing over a reverse curve.
My invention relates to pivotal connections for locomotives and is especially designed to connect the high and low pressure engines of the Mallet articulated type.
The objects of my invention are to permit radial movement and vertical angling between the two parts of the locomotive without strain upon the frame of the locomotive itself or upon the track rails.
Referring to the drawings, 2 is the leading or low pressure engine and 3 is the trailing or high pressure engine. The engines 2 and 8 are connected by a casting 4 which is attached to the trailing or high pressure locomotive by means of a vertically disposed pivot pin 5. The casting 4% has a rectangular shaped aperture 6 for the reception of the bearing block 7 which takes about the pin 5, and'which is adapted to slide laterally and horizontally in the aperture or slot 6. The pin 5 is carried in registering apertures 8 of the studs 9 which project from the cross frames 10, and the cross frames 10 are suitably secured to the main frames 11 of the engine 3. The studs 9 also hold the bearing block 7 in place in the slot 6 of the casting 4.
The casting 4. has at its forward end arms 12, which are apertured for reception of the horizontally disposed pivots 13. The pivots 13 are mounted on lugs 14; of the cross Specification of Letters Patent.
Application filed August 31, 1912.
' Patented Mar. 17, 1614.
Serial No. 717,991.
It is obvious that many changes may be made in the device which I have shown and described herein without departing from my invention.
What I claim is:
1. In a locomotive of the Mallet articulated type, a connection between the two engines thereof, said connection comprising a member of substantially U-shape pivoted to one engine to swing in a vertical plane, and lying normally in a horizontal plane, said member having a rectangular aperture, a bearing block slidably mounted in said aperture, carried by the said member, and
a pin mounted on the other engine and passing through said bearing block.
2. In a locomotive of the Mallet articulated type, a connection between the two engines thereof, said connection being comprised of a rectangularly shaped horizontally disposed member having an, aperture therein, the said member being pivoted to one engine by a horizontally. disposed pivot and to the other engine by a vertically disposed pivot, a bearing block mounted in and carried by the said member taking about the vertically disposed pivot, the said bearing block being held from vertical movement and being free to move in said aper ture laterally in a horizontal plane.
