We have recently received details of an interesting new device, which is designed chiefly for facilitating operations on the road springs of vehicles, such as the removal of shackle-pins and the fitting of new bushes to the spring eyes. This apparatus is known as the Brima spring jack, and is marketed by William Clark, Ili, Gt. Dover Street, Londou, S.E.1.
It is intended, as indicated in an illustration on this page, to be placed over the read spring concerned, its lifting crossbar coming into contact with the upper spring or dumb-iron. A ratchet arrangement is employed for the operation of the jack, a few turns of the ratchet wheel taking the tensien from the spring and thus enabling the shackle-pin to be quickly removed. Should it be desired to remove the bush from the eye of the spring, the last-mentioned can be further compressed clear of the dumb-iron with the aid of the jack, thus clearly exposing; the bush for removal with a drift.
It is stated that the Buma jack cane not slip when in use on a vehicle and, in support of this contention, it is claimed that a vehicle was recently driven six miles with one of these devices supporting a spring from which the forward shackle-pin had been removed. This seems to indicate that the apparatus should prove to be of much use in certain cases of breakdown.
We are also informed that the Bunia spring jack is marketed in a special form, having a fiat base and an .extensign handle, so that it can be used, if so desired, as an ordinary lifting jack.
