Electric storage batteries
Abstract
Abstract A method of providing mounting means and/or lifting means on the external wall of a battery box comprises starting with a moulded mounting or lifting member which is formed with a peripheral skirt extending from the surface thereof to be presented to the battery box and with an integral projection defined within the skirt and extending therefrom, the skirt and the projection defining a channel therebetween. A heater is placed between the projection and a portion of an external wall of the battery box from which the mounting or lifting member is required to protrude and said portion of the battery box and the projection are urged into contact with the heater. The heater is then withdrawn and the mounting or lifting member and said portion of the battery box are pressed into engagement with one another to secure the member to the battery box with the skirt abutting against the external wall of the battery box. Molten material displaced from the projection during the heating step is received in the channel.
