Application filed June 1,
To all whom, it may concern: Be it known that we, FRnnnnroK W.. PAR- United States, and a resident of Elmira, county of Uhemung, and State of New York, and FnANois A. JIMER- soN, a citizen of the United States, and a resident of Athens, county of Bradford,
"State of Pennsylvania, have invented a certain Built-Up Crank Shaft, of which the following is a specification accompanied by drawing shafts for fluid actuated multi-cylinoler engines, and the objects of the invention are to simplify and strengthen such crank shafts, obtain better balance. and more perfect align- This invention relates to built up crank ment of bearings, and permittheuse in the invention is to engine of solid end connecting rods, rather than multiple piece connecting rods or rods object of the f of the toggle type. Another enable the parts to be readily assembled and disassembled. a To these ends, the invention is illustrated in one of its preferred forms in the accomf panying drawings, in which Figure 1 is a side elevation partly in lonsection of an assembled crank shaft,
Figure 2 is an end view of the crank shaft,,
Figure 3 is a transverse sectional view on the'line 33.of Figure 1, looking in the direction of the arrows, and illustrating the method of'disassembling the parts,
Figure 4 is a view similar to Figure 3,
with the central bolt through the center web c of the crank shaft in position,
Figure 5 is a side elevation of one end web and crank pin,
Figure 6 is a transverse sectional view taken through the center web, andend web and 1 tion of is a side elevation of the oppositecrank pin. p l p i Referring to the drawings, the crank shaft comprises the center web having transverse apertures B ateach end for the recepthe crank pins C, which to be located and aligned in the center web in any suitable manner, preferably by means Flgure 7 and a bolt R ends and transverse apertures at 1922. steam. 565,067.
of the locking pins D assin throu h the center web and the cran k pins? g The shaft end webs G and H carrying the crank pins end webs G and H. The end webs G and H are also referably provided with counterwelghts and K. The shaft ends E and F alsocarry the'main bearings L and O which ends E and F, are provided C, which are formedintegral with said JERSEY maybe in the form of ball bearings, and the drlving pinion P is shown keyed tothe shaft end E.
. In accordance with my construction, the center web A is formed with tudinal slot Q in the body portion of the web connecting the transverse apertures B,
having the nut passes cenbody tightly? together when the parts are assembled, thus rigidly gripping the crank' 111s loosening the crank pin C which may be readily removed. Y Y
the transverse apertures in the center shaft and locating means for aligning the means for locking the web firmly to the crank pins.
