An Improved Method of and Means for Attaching in Position Gas
and other Bracket Blocks and the like.
I, JOHN LEWIS, Plumber and Gasfitter, 8, Moor Street, Chepstow, Mon., do
hereby declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
-
My invention relates to an improved method of and means for attaching in
position gas and other bracket blocks and the like, and the objects are to prevent
damage to the walls and other inconveniences which accompany the usual method
of fitting gas blocks and to obviate the practice of plugging the walls previous to
fixing the blocks. In carrying my invention into practice I proceed in or in about
the following manner making reference to the accompanying drawings, Figs. 1 to 5
of which show isometrical views of various forms of the appliance I use. Fig. 6
the cross section of a modification and Fig. 7 a longitudinal section of a wall with
the appliance in use. Briefly described the appliance consists in a special spike or
a particular kind of holdfast for driving into the wall or other surface and having
either a shouldered end or a radial arm or radial arms at right angles to the axis
of the spike.
Referring to Fig. 1a is the spike having a shoulder and a projecting end c
which is bored and screw threaded at d to receive the ends of one of the screws
used to hold on the block. The spike is to be driven in preferably by a tool having
a hollow end fitting over and pressing on the shoulder b. In Fig. 2 the spike is
terminated by an arm e in Fig. 3 by two arms e in Fig. 4 by three arms c
and in Fig. 5 by four arms &³, the end of each arm being in every case bored and
screw threaded at d. In order to facilitate the driving in of the arm or arms e,
el, e², &e they may be of triangular cross section as at Fig. 6 the edge f being
on the spike side of the arms. In the longitudinal section Fig. 7 g is the wall,
h the plaster, a the spike, the arms, the bracket block and the screws for
attaching to e¹. It should be noted that the.spikes are driven in so that the outer
surface of the arms or of the face e shall be flush with the outer face of the plaster,
and it is obvious that the appliance can be used either before or after plastering
and finishing. It is proposed to make the appliances of malleable iron but they
may be made of any other suitable metal.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is:-
1. The improved method of attaching in position gas and other bracket blocks
and the like by screwing them to special spikes or holdfasts substantially as
described in the above specification and exemplified in the accompanying drawings.
2. The improved spike for use in attaching in position gas and other bracket,
blocks and the like, the said spike having a shouldered outer end and screw
a

page_text: threaded axial hole therein substantially as described in the above specification
with reference to Fig. 1 of the accompanying drawings.
3. The improved holdfasts for use in attaching in position gas and other bracket
blocks and the like, the said hold-fasts consisting essentially of a spike terminated
by an arm or by more than one arm, at right angles to the axis of the spike and
having a triangular or other cross section, each of the said arms being provided
with a screw threaded hole at its outer end and the axis of the said hole being
parallel with that of the spike, the whole substantially as described in the above
specification and exemplified in Figs. 2 to 6 of the accompanying drawings.
Dated this 21st day of November 1898.
