Figure 2 is a front view of the locomotive underframing drawn to an enlarged scale, the end of the frame proper being shown at the right a hand side of the figure and the pilot being shown 0 at the left hand'side of the figure.

. Figure 3 is a top view of the structure indicated in Figure 2 andis taken approximately on the 0 line 3-4 of Figure 2. 1

Figure 4 is a side view of the structure shown "in Figures 2 and 3.

At the front end of the underframe casting is the deck plate 1 terminating in a pilot beam I! to which is secured the pilot I3 by means of the bolts Ila. The pilot includes forwardly tapering or streamlined transverse members l4 and I5 connected by ties Hi. Secured to the bottom transverse member I5 is a plate 11 having a re-' inforcement I8 at its lower edge. Member ll forms the lower edge of the pilot and has slots 2| receiving thebolts whereby this member may be vertically adjusted to maintain the same at a uniform distance above the rails regardless of variations in the thickness of tl'tie wheel tires due to turning or renewing 'thereof. ,Members l4 and II are also arranged for attachment of the front streamline casing l9, thiscasing being conveniently welded or bolted to its supporting members. The member I1 is located on the outside of the front casing.

The pilot beam I! to which the pilot is secured has rearwardly divergingendportions 22 alined with the upper member l4 of the pilot, which portions are also arranged for mounting the streamlined tront casing. Projecting above the front deck I on each side are the brackets 23 for mounting various pumps, and these brackets are connected by a curved member 24 which supports the front casing l9 above the pilot and the pilot beam. Projecting from eachsteam cylinder 4 is 5 the casing mounting arm or bracket 25 and the bracket 28. Extending between the lower extremities of arms 26 and the lugs 21 at the ends of lower member [5 of the pilot, and between the brackets 28 and recesses He at the ends of the pilot beam are the

structural members

28 and 29 suitably shaped for supporting adjacent parts of the streamline casing.

Also secured to the pilot beam I! by means of the bolts 30 extending through slots 30a is a bracket, generallyindicated at 3i, and having forwardly projecting arms 32 including the

bearlugs

33 and 34. Pivoted to the bearings 33 by means of the pin 35 is the swinging coupler 36 having a counterbalance extension 31 at the rear end thereof arranged to engage a stop 38 on the underside of the front deck structure to limit the downward swinging of the coupler. A door 39 hinged to the front casing I9 may be swung downwardly over the coupler opening therein to complete the front streamlining when the coupler is in the lowered inoperative position illustrated in dotted lines in Figure 3 and also in Figure 4. A pin 40 is detachably seated in the bearings 34 at the front ends of arms 32 for securing the coupler in the raised or operative position. The coupler bracket is vertically adJustable independently of the pilot by means of bolts 30 and slots 30a.

Various features of the structures described in themselves do not constitute the present invention and these maybe altered as desired and also various inventive features may be modified as will occur to those skilled in the art, and the exclusive use of all such modifications as come within the scope of the appended claims is contemplated.

I claim:

1. In locomotive end structure, an end memher, a pilot immovably secured thereto, streamline casing carried by said pilot, a coupler mounted on said member and movable independently of said pilot and casing from a projected position in which it extends outwardly of the normal contour 01 said casing to a retracted position within the normal contourv of said casing.

2. In a locomotive front end structure, a pilot, a coupler constructed and arranged to project outwardly from said pilot or to be recessed therein, and streamlined casing for the front of the locomotive constructed and arranged for said coupler to project forwardly, thereof when extended or to enclose said coupler when the latter I is retracted.

3. In a locomotive front end structure, a pilot, a. casing having a rounded nose for streamlining the trout end oi the locomotive, there boin: an

' oypenin: in said nose and a movable member for smoothly closing said opening, and a coupler mounted on said pilot to be projected through said opening or to be moved to a retracted position wherein said member may be moved to close said opening and overlie said coupler.

4. Railway vehicle end construction including a mbstantially continuous streamlined wall deberisnotinuse.
