Application esi lay 7,
To @ZZ whom t may concern i Be it known that I, FRANCIS A. ,inane- SON, a' citizen of he United States, end a resident of Athens, county of Bradford, State o1 Pennsylvania, have invented e, cerm tain Built-Up Crank Shaft, oi. which ehe' following is a specification accompanied by drawings.
lThis invention reietes to built up crank shafts for Huid actuated muitieylinder engines, and the objects of Jhe invention are to simplify and strengthen such crank shafts, obtain better balance and more per feet alignment',A of the bearings, and permit the use in the engine of solid end connectl ing rods, rather than multiple piece co'nneet-ing rods or those or" the toggie ype., Another object of the invenion is to enable the arts tov be readily assemhied and dises. sem led. V
A further objectl of the inveniion 4is to provide the hearing portions 'oi' the empli pins in the form of sleeves carried by he center web of, the crankl shaft, ihrough which sleeves the crank pins are inseried.
To ailof these ends the4 invention is shown in one 'ofits preferred iorinsin theaccompany drawings .in whichn Figure l is a side elevarion artly in -longitudinal section of en' asseinb ed crank shaft.
Figure 2 is en end View of Figure l.
l Figure 3 is a ,ransverse sectional View of Figure l on she line 3--3 iooking in the direction of the arrows, Figure 4 is aside elevation of one of the end webs withits crank pin,
f shaft comprises the center web Figure, 5 is e longitudinal, sectional elevea tion of the center web end sleeve portions, and f Figure 6 is a side elevation of the other end web and crank. pin.
Referring to the drawings, the crankv A having sleeve portions B integral therewith and ex- `tending outwardly in opposite directions et each end ofthe web to forni the hearingl portions of the crank pins C, which ere adapt- 'ed to be inserted through the'sieeve por gfions and secured to the webs as by means 'to `he center weba in aceordance Wish niy consrneion, the
crank are provided with sieeve hearing poriions B which noi oniy serve the usuel functions of hearings, but sei; as spaeing 11i-embers for spec-ing sperrt `ehe webs of he crank shaft and :idd to the strength of the entire sirue't-ure. The crank pins are readily inserted into the sleeve bearilw portions i3 or withdrawn therefrom, en
are securely vheld in position in a simple .manner when ehe paris are assembied.
l claim:
l. A built up crank shafl; der engines, comprising e cener web having sieeve portions inzegral herevvith and extending outwerdiy in opposite directions at each end of the web ro forni the bearingportions of the crank pins, shai's ends ailing end ceri-ying crank pinsinegrai therewith endadaped to he inserted throughsaidsieeve portions of the center web, and means for securing the crank pins for moisi-cylin- 2. vA huile up crank shais for mulei-eylin-v der engines, comprising s, center web hav mg sleeve portions inaegrei-herewith and extending outwardly in on osiie directions l En teseimeny whereof have signed this specification.
