Abstract
530,364. Connecting mattress &c. springs. DAVIS, J. M. July 13, 1939, No. 20454. [Class 83 (iv)] A tool for securing together the ends of the springs of spring interiors for cushions, mattresses &c. by tie wires, consists of a pair of fluid operated dies, one of which has a T-shaped recess and the other a pair of grooves lying parallel with the centre limb of the T-recess. The tie wires, are formed with a series of lateral U-bends each limb of the bend being of S-form as shown in Fig. 8. The bends are clenched over the overlapped ends of the strings in order to secure the rows together, the inner bends 2a being engaged over the outer coil 10 and the bends 2b at the free end being engaged under and over the. subjacent coil 9. The clinching tool comprises a pair of pivoted jaws 20, 21 at the end of a portable pneumatic ram 22, the jaw 20 having a T-shaped recess 24 and the jaw 21 having an inclined face provided with a U-shaped groove 28, 29 with open ends. The tooling may be provided with a press button or trigger-operated valve and is provided with an adapter for connection to a source of fluid pressure. Specifications 630,363 and 515.821, [Group XIV], are referred to.
