Abstract
732,381. Two-part couplings combined with switches. SCHEID, A. M., SCHEID, W. M., and SCHEID, E. M., [trading as VORWERK & CO.]. Oct. 29, 1952 [Nov. 16, 1951], No. 27208/52. Class 38 (1). In an appliance such as a vacuum cleaner having a built-in switch 5, the supply from the switch is passed through a pair of spring contacts 14, 15 which normally engage and form a socket for a plug 9 of an auxiliary device such as a heating resistance, whereby the latter can only be switched on with the vacuum cleaner. When the auxiliary device is to be connected in series with the appliance, the plug comprises a pair of parallel contacts insulated from each other and each engaging one of the spring contacts. Otherwise two pairs of spring contacts and solid plug pins are provided. In the construction shown, contact 15 is mounted on a fixed part of the appliance casing 3 and contact 14, with the switch, is mounted on a removable cover 4 which may therefore be removed without disconnecting any wires.
