' Application filed ()ctober 22, 1827. Serial No. 227,916.
. The object of our invention is to make a locomotive frame, of the type in which the cylinder structure is located between upper and lower arms of the frame, in such manner that it can be made as an integral castlng which can be machined, and then cut to allow for the insertion of thecylinder structure, the cut portion being replaced and welded'or otherwise secured at the point where it had been previously cut.
In the accompanying drawing:
Fig. 1 is a side view of a locomotive frame made in accordance with our invention;
Fig. 2 is an enlarged side viewof the front:
end of the frame;
Fig. 8 is a transverse sectional view of the two side frames on the line 3'3', Fig. 2, showing the cylinder structure in position; and
Fig. 4 is a detached side view of the upper arm which has been severed from the main casting to allow for the insertion of the cylinder structure.
1 is a frame having the usual pedestals 2 connected together by portions 3. The forward end of the frame is forked, 4 being the lower arm and 5 the upper arm. These arms are spaced apart to fit the cylinder structure 6 shown in Fig. 3. p
The cylinder structure in the present instance is the ordinary two-cylinder structure of a high-pressure locomotive, but it will be understood that any type of cylinder structure may be used without departing from the essential features of the invention.
The arms of the frame are secured to the cylinder structure by bolts in the present instance, as shown in Fig. 3. Shoulders 7 and 8 on each arm 4 and 5, respectively, of the frame fit against the ends of the cylinder structure. The end portions of the arms 4 and 5 are located close together and extend parallel one with the other as illustrated'at 4 and 5, Fig. 2. The foot plate of the locomotive is located between the end portions of the arms, and the arms are perforated for the passage of securing bolts.
The frame casting 1 is made as a unitary structure and the entire frame machined while the partsa-reintegral, thus insuring acit was severed.
between the lower arm; I p 7 After .the cylinder. structure has been placed in position then theupper arm 5 is shoulders 7 and 8j of the said N located in position on the cylinder casting,
with the severed end abutting that of the main frame; Then the two parts which were previously severed are welded or otherwise secured'on the line w w, Fig. 2, so that. the castmg becomes an lntegral structure with the cylinder structure located mproper position, the welding being preferably accom' previously severed. 1
The particular design of frame will vary with the particular type of locomotive, We claim L 1. The process'herein described ofassem bling locomotive frames and cylinderstructures, said process consisting in making a frame having two integral arms at one end; machlmng the entire frame lncludlng the arms; then severlng one of sald arms from the frame; locating the cylinder'structure in V ositionthen re Jlacin the severed armand 7 I a 7 securing the arm permanently to the fram at the point where it was severed. j 2. The process herein described of assembling locomotive frames and cylinder-structures, said processconsisting in making a frame having two integral arms'at one end; machining the entire frame including the arms; then severing one of said arms from the frame; locating the cylinder structure in position and-securing it to the other arm; then replacing the severed arm, securing it to the cylinder structure; and securing the arm permanently to i 3. The process herein described of assembhng locomotive frames and cylinder struc- I tures, said process consisting in making the side frames of the locomotive with pedestals I and two arms at the forward end'spaced apart for the reception of acyhnder. structure; severing the upper arm from the frame;
.removin said armlacin the .c linder the frame at the point where moutnting the severed upper arm on the cylinder structure with the severed end of the frame; securing said arm to the cylinder structure; and Welding the abutting ends of theframe and arm together to form a unitary structure. p
4:. A locomotive frame made in a single casting, said frame having pedestals and-two longitudinal arms spaced apart at the forward end and shaped to fit a cylinder casting, one of the arms being so formed that it can be severed between the part to be secured to a cylinder and the first pedestal, to allow for the insertion of the cylinder, and then replaced in position and Welded to the frame. V 5. A locomotive frame made ina single casting, and having two arms'at the forward end, one arm being directly above the other arm, said arms being spaced apart forthe reception of a cylinder structure,' each arm having a shoulder at each end arranged to abut the cylinder structure, said arms having parallel extensions spaced apart for the reception of a foot plate of the locomotive.
