HARLES EOLIQ, OE EALTIEZOELE, MARYLAND.
EEA'NDBEL FOB SQUABING- PI$TQNS Application filed August 1'2 To all whom it may cancer? Be it known that l, CHARLES E. Four, a citizen of the Jnited States, residing at Baltimore, in the State of Maryland, have invented certain. new and useful improvements in l /landrels for Squaring Pistons, oi which the following is a specification.
The invention relates to improvements in mandrels for squaring pistons, and has for its object to provide a simple, cheap and etficient device for setting pistons through on the crank shaftv The invention consists of the novel construction and arrangement of the parts and combination of parts hereinafter more fully s forth in the following specification and Cl) pointed out in detail in the appended claim. in the accompanying drawing,
Figure l is a side view of my invention projecting through the end of a connecting rod and showing the piston being squared thereon.
Figure 2 is an enlarged side view of the mandrel.
Figure 3 is an end view of Figure 2.
Referring to the accompanying drawing forming part of this specification and in which like reference numerals designate like parts throughout the several views thereof, 1 designates the mandrel which is round at one end and has its opposite end cut away to form the flat top 2 and sides 3, the that upper side 2 being for the purpose of hold- 6, 1920. Serial l lo. 406,204.
ing the square when the piston is being squared on the connecting rod. The flat sides 3 are clam "Jed between a vice (not shown) or other suitable tool for holding the mandrel when in use. The end of the mandrel having the fiat top and sides is smaller in diameter than the rounded end.
ine round one ol the mandrel 1 is placed in the end of the connecting rod 4} as shown in Figure l, and the square 5 is placed on the flat surface 2 of the mandrel with its upper edge projecting against the outer surot' the piston 6 and when the latter is perfectly square on the rod lthe mandrel l is removed from the rod 4- and piston 's then connected up to the crank shaft of he engine. The edges 7 of the upper surface 2 is slightly bevelled to prevent injury to the said surface 2 when the device is clamped in a vice or other holding means.
