Abstract
The crosshead has a body formed of solid, metal plate, and of substantially U-shape. It comprises a pair of spaced-apart parallel limbs which are bridged between by an integral transverse member, and the latter is bored through to receive a piston rod therein. Shoe plates are joined to the limbs to guide the body in reciprocation. In the combination with a connecting rod assembly and a piston rod, an end of the piston rod is directly fastened to the connecting rod assembly, and the crosshead is coupled to an intermediate portion of the piston rod.
Claims8
A crosshead, comprising:
- a body formed of solid, flat, metal plate of uniform thickness;
- said body having a pair of spaced-apart, substantially parallel limbs, and a single transverse member integral with, and bridging between said limbs;
- wherein
- said limbs, as aforesaid, are solid, of said uniform thickness, and devoid of any throughgoing boreholes;
- said transverse member has a borehole formed therethrough in which, slidably, to receive a piston rod;
- and further including
- shoe plates joined to said limbs 8.
In combination, a connecting rod assembly, and a piston rod, comprising:
- a crosshead body formed of solid flat, metal plate of uniform thickness;
- said body having a pair of spaced-apart, substantially parallel limbs, and a single, transverse member integral with, and bridging between said limbs;
- wherein
- said limbs, as aforesaid, are solid, of said uniform thickness, and devoid of any throughgoing boreholes;
- said transverse member has a borehole formed therein through which to receive a piston rod;
- and
- a connecting rod;
- wherein
- said connecting rod has a given, hollow end formed of a substantially barrel-shaped wall;
- said wall has an opening formed therethrough
- said transverse member is set in said opening;
- and further including
- a crosshead pin, disposed within said wall, having a tapped hole formed therein;
- and
- a piston rod in slidable penetration of said borehole and having a threaded end threadedly engaged with said tapped hole.
In combination, a connecting rod assembly, a crosshead, and a piston rod, comprising:
- a crosshead body having only a single borehole formed therein and therethrough;
- a connecting rod assembly;
- and
- a piston rod in slidable penetration of said borehole and having an end fastened directly to said connecting rod assembly.
