Abstract
742,442. Making piston assemblies. CARRIER ENGINEERING CO., Ltd. Nov. 3, 1953 [April 16, 1953], No. 30400/53. Class 83 (2). [Also in Group XXVI] A method of assembling a piston and an eccentric strap comprises attaching the strap by a wrist pin to support means while said means are without the piston skirt, and then inserting the assembled strap and support means within the piston skirt and securing, e.g. by welding the support means to the inner face of the piston head to depend within said skirt. A piston 2 is fabricated from a tubular skirt 4 and a stamped head 5 to which are brazed or welded apertured lugs 6 the head resting in a recess 4<SP>1</SP> in the skirt. The walls of the openings 7 in the lugs are slit for clamping around a wrist pin 15 disposed in the small end 9 of an eccentric strap 3. In assembling, the lugs are welded to the head and then drilled to form the openings 7 after which the slits 8 are cut. The piston skirt 4 is then placed over the shank 11 of the strap, the strap head 9 placed between the lugs 6 and secured to the head by the wrist pin 15. Finally, the assembly is placed in a jig to obtain accurate alignment between the piston skirt and the opening 14 of the strap and the piston head 5 is brazed to the skirt 4. The slits may be made large enough to permit the wrist pin to be inserted into the openings 7 through the slits after which the pin is held in position by filling the slits with solder or weld material. In a modification, the piston may have an integral body and head portion 20 and 21 respectively formed by deep drawing a metal sheet. The pin support in this instance comprises a U-shaped member 23 having aligned openings 26 which is first assembled on the strap end 28 and then placed within the piston body 20 in contact with the piston head 21 and brazed or welded in position.
