Improvements in Screws.
MARIA WOOLLEY and EATON WOOLLEY both of No. 23 Kensington Crescent,
Kensington London, Lady & Gentleman do hereby declare, the nature of this
invention to be as follows:-
Our invention relates to screws more especially designed for the construction of
wooden beams fixed in ship building, waggons, life boats, bicycles etc. and also
applicable in many other ways. Manufactured in any size, or metali deemed
desirable for the purpose to which it is to be applied, & in as many pieces. as the
manufacturer may think necessary. Our invention consists of an ordinary screw
with a hollowed shank constructed so as to allow two horizontal over lapping prongs
to protrude. From the head of each prong is a wire carried up the centre of the
hollowed shank to the head of the screw which by pulling will allow the prongs to.
protrude when the screw is firmly fixed into the substance with which it is in con-
tact with. The purpose of the screw is to prevent continual movement from loosening
the beams & being hollow would be an advantage in many ways. In cases of need
the screw can also be extracted as it is so formed that a wire is attached to the end
of each prong which will be in the part of which projects in a groove. The hollowed
shank will only be large enough for the wires to be enclosed & each wire, or chain
will have a small head to prevent it from dropping down the centre.
The screw has
a movable head, the thread going the same way the screw turns, so as to prevent
the head coming off before it is required to do so & the head of the screw will have
the thread continued round if necessary so that should it be desired the screw can
be completely embedded. The upper part of the hollowed shank will contain two
blocks projecting inwardly & the head will have places made to receive them so
that the screw may be turned whichever way desired without the head of the screw
coming off, & if necessary it will have attached to it rings into which ordinary screws
may be fixed so that in no possibility can the screw move. If required this screw
can be used for its lightness alone when the internal part would not be desired &
the head need not be movable unless necessary. This screw can be made with a
perforated shank & after being driven into metal it can be filled with oil to prevent
the screw from rusting in same.
