Claim 1
Independent Claim
117 words
THE METHOD OF MAKING COMPOSITE ARTICLES OF METAL PARTS AND RESILIENT MOLDABLE MATERIAL WHICH COMPRISES MOUNTING THE METAL PARTS BETWEEN MOLD MEMBERS HAVING METAL-FORMING SEALING ELEMENTS NON-COMPLEMENTAL TO THE METAL PARTS, APPLYING PRESSURE TO THE MOLD MEMBERS IN A DIRECTION TO FORM PORTIONS OF THE METAL PARTS COMPLEMENTAL TO SAID ELEMENTS BY DISTORTION OF THE METAL OF SAID PARTS UNDER SUCH PRESSURE AND THEREBY TO ENGAGE SAID ELEMENTS WITH SAID PARTS TO SEAL OFF A CAVITY BETWEEN THE METAL PARTS, THEN WHILE HOLDING THE MOLD MEMBERS AND THE METAL PARTS IN SUCH CLAMPED AND SEALED RELATION FILLING THE CAVITY BETWEEN THE METAL PARTS WITH PLASTIC RESILIENT MATERIAL UNDER PRESSURE, AND REMOVING THE ARTICLE FROM SAID MOLD MEMBER.

Claim 3
Dependent Claim
140 words
APPARATUS FOR MAKING COMPOSITE ARTICLE OF CONCENTRIC METAL BUSHINGS AND RESILIENT MOLDABLE MATERIAL THEREBETWEEN, SAID APPARATUS COMPRISING MATING MOLD MEMBERS DEFINING A FORMING CAVITY THEREBETWEEN, HARDENED METAL INSERTS NON-COMPLEMENTAL TO SAID METAL BUSHINGS IN THE CAVITY, SAID MOLD MEMBERS BEING ARRANGED IN CONCENTRIC RELATION TO SAID METAL BUSHINGS, EACH INSERT HAVING A SHARP UPSTANDING ANNULAR KNIFE EDGE POSITIONED TO CONTACT THE END OF A BUSHING AND TO BE FORCED INTO THE METAL AT AN END OF THE BUSHING TO SEAL OFF A CAVITY BETWEEN THE CONCENTRIC BUSHINGS BY DISTORTION OF THE METAL OF SAID BUSHING UNDER PRESSURE AND THEREBY TO ENGAGE SAID KNIFE EDGES IN SEALING RELATION TO SAID BUSHINGS, AND MEANS TO CLAMP THE MOLD PARTS WITH THEIR INSERTS IN SEALED RELATION WITH THE ENDS OF THE BUSHING WHILE THE CAVITY IS FILLED WITH PLASTIC RESILIENT MATERIAL UNDER PRESSURE.
