IMPROVEMENTS IN THE CONSTRUCTION OF GAS PLIERS AND GAS TONGS
Year: 1885

page_text: We, HUGH CULTRA GILCHRIST, of 70 Atlantic Road, Brixton, in the County of
Surrey, Ironmonger, and CHARLES BELLAMY, of 3 Park Terrace, Streatham, in the
County of Surrey, Mechanic, do hereby declare the nature of our said invention
for "IMPROVEMENTS IN THE CONSTRUCTION OF GAS PLIERS AND GAS TONGS," and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being had to the accom-
panying drawings, and to the letters of reference marked thereon, that is to say
By this our invention we provide gas pliers and gas tongs which are more
powerful, more durable, and easier of operation than the gas pliers and gas tongs
now in use
A great defect in gas pliers and gas tongs, as hitherto constructed, 18 their
tendency to slip, more especially when used to unmake an extra tight, or an old
rusted joint This necessitates the exercise of a great deal of strength to get them
to bite This great defect is entirely obviated by this our invention, as we so
construct the jaws of our gas pliers and gas tongs that all tendency to slip is
prevented, thus the unmaking of an exceedingly tight joint is rendered com-
paratively an easy matter (a very perfect grip being obtained with a far less
expenditure of power than is required with the ordinary pliers and tongs).
These our gas pliers and gas tongs are moreover simple in construction, and
inexpensive in manufacture
This our invention consists in constructing the one jaw of gas pliers and gas
tongs with teeth which have an inclination towards the nose of such pliers and
tongs, and the other jaw with teeth which have an inclination in the reverse
direction The one set of teeth thus act contrary to the other set, and prevent all
tendency to slip
This our invention further consists in constructing gas pliers and gas tongs with
holes for different diameters of pipes, which holes, instead of being separated from
each other by a bridge, (as in two-hole pliers of ordinary construction) are joined
together, that is to say, the rear part of the front hole joins the front part of the
hole in rear of same
These our gas tongs may be constructed to take one, two, three, four, or more
Bizes of pipe, as required, without materally increasing the weight of tool
This construction of gas tongs is particularly advantageous as it dispenses with
the necessity now existing with respect to gastongs of the ordinary construction of
carrying a number of tongs so as to suit different diameters of pipes

page_text: And in order that this our invention may be fully understood reference is had to
the accompanying drawings, and to the letters of referente marked thereon
Figure 1, shews a pair of gas pliers, constructed in accordance with this our
invention, having one jaw A with its teeth a inclined towards the nose of pliers,
and the other Jaw B with its teeth b inclined in the reverse direction.
Figure 2 illustrates a pair of two hole phers constructed in accordance with this
our invention, that is to say, with the two holes C, D, joined together, the rear
part of the front hole C being joined to the front part of rear hole D
Figure 3 represents a pair of gas tongs constructed according to this our
invention, and adapted to take several sizes of pipe Though 3 holes are here
shown, each of which may be adapted to two sizes of pipe, it must be understood
that such tongs may be constructed with any number of holes, as suitable or
requisite, without departing from this invention
Having now particularly described and ascertained the nature of this our
invention, and in what manner the same is to be performed, we declare that
what we claim is
First, The construction of gas pliers and gas tongs having the teeth of one jaw
inclined towards the nose of such gas phers and gas tongs, and the teeth of the
other jaw inclined in the reverse direction, substantially as and for the purposes
herein before set forth and described
Second, The construction of gas pliers with holes for different sized pipes,
which holes, instead of being separated from each other as usual by a bridge, are
Joined together, substantially as and for the purposes herein before set forth and
described
Third, The construction of gas tongs with two or more holes for the purpose of
taking different sizes of pipe substantially as herein before set forth, and described
Fourth, The general arrangement and construction of gas pliers and gas tongs,
substantially as and for the purposes hereinbefore set forth and described
