362,574. Flexible joints. CHRYSLER CORPORATION, 341, Massachusetts Avenue, Detroit, Michigan, U.S.A. Oct. 1, 1930, No. 29414. Convention date, Dec. 27, 1929. [Class 65 (ii).] In a method for assembling a flexible joint such as used between the springs and frame of a motor vehicle and comprising rigid inner and outer sleeve members 12, 10 and an intermediate elastic member 14, the elastic member is inserted in the outer member and the inner member is then guided from its opposite ends while being inserted through the elastic member. The elastic ring 14 is pressed into the outer sleeve 10 by the machine shown in Fig. 1 which comprises a base 16 having a block 18 and an axially adjustable pilot member 20 over which the sleeve 10 is fitted. Mounted in a crosshead 34 by detachable members 38, 40 is a cylinder 36 containing a piston 42 urged upwards by a spring 54 and adapted to be moved downwards by compressed air admitted above the piston from a pipe 56. The piston carries a plunger 44 to which is detachably mounted a tool 48, 70 with a head portion 62 of diameter equal to the smallest diameter of a tapered sleeve 60 slidably and detachably mounted on the rod 70. In operation the sleeve 10 is held between the block 18 and an annular recess 72 in the lower part of the sleeve 60 and the elastic ring is placed in the upper end of the sleeve 60 from which it is pressed into the sleeve 10 by the piston, the pilot 20 serving to limit the downward movement of the ring. Fig. 3 shows a machine for inserting the inner sleeve. The outer sleeve and elastic ring are held in a die 84 resting on the upper surface of a die 76 of internal diameter equal to the outer diameter of the inner sleeve and are clamped at the top by a detachably mounted cap 88. The lower end of a pistonactuated plunger 110 carries a block 122 having resilient upper and lower faces 124 and a member 128 of diameter equal to the internal diameter of the sleeve 12 which is frictionally'held thereon by a spring-pressed ball 130. Similarly held on the lower end of the sleeve 12 is a taper 132. On the downward movement of the piston the taper and sleeve are pressed through the elastic ring, being axially guided at the bottom by a seat 144 mounted on a piston 142 in a chamber 138. When the plunger returns to its original position the sleeve 12 remains in the ring 14 and on the removal of the cap 88 the assembled sleeves and the taper are forced out by the pressure in the chamber 138 built up by the downward movement of the piston 142 or by the admission of compressed air. In a modification the sleeve 10 is held on a block by spring-actuated jaws and the ring 14 rests on a sleeve projecting above the block into the sleeve 10. The insertion of the taper presses down this projecting sleeve against the action of a spring and also forces down a guiding piston as before, the action of the spring and the back pressure of the piston together serving to remove the assembled members.
