PROVISIONAL SPECIFICATION.
A New or Improved Puttying Device.
We, ALBERT JAMES BLAKE of St. James Street, Portsea and RALPH
HEGINBOTHAM of 24 High Street, Stalybridge, Cheshire, Gentlemen do hereby
declare the nature of this invention to be as follows:-
This invention relates to an instrument to be used in puttying, and has for its
object to provide a device which will supply the putty automatically to the required
part at a suitable speed.
The instrument consists of a tube or cylinder, having a conical cap at one end,
with an opening, preferably rectangular, and inclined at an angle to the cylinder
forming a nozzle. Within the cylinder moves a piston, attached to a rod which
extends through the other end of the cylinder and having a strong spiral or other
spring bearing on it, tending to force it towards the nozzle. The rod is provided
at its end with a finger piece or handle, by which it can be drawn back against
the spring. It is also formed with a number of ratchet teeth along one side,
and a small spring pawl is pivotted to the cylinder, projecting through it and
furnished with a finger piece so that it can be raised from the rod, when desired,
by pressing on the projecting piece.
The piston can thus be stopped at any point, by releasing this pawl. The
cylinder is filled with putty as far as the piston will allow, it being drawn back
as far as possible.
In using the instrument it is held to the part to be supplied with putty, and
the pawl is released, allowing the spring to act, forcing the putty from the
aperture. Two nozzles may be employed, one for use at first in putting the
putty on roughly and the other for finishing. With this device a window may
be glazed with far less trouble and at much greater speed than heretofore.

COMPLETE SPECIFICATION.
A New or Improved Puttying Device.
We, ALBERT JAMES BLAKE of St. James Street, Portsea and RALPH
HEGINBOTHAM of 24 High Street, Stalybridge, Cheshire, Gentlemen, 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:
This invention relates to an improved device to be used in connection with
glazing, intended to provide an arrangement by which the putty can be applied
in an automatic manner, thus allowing the work to be done much more rapidly
than is the case at present.
The instrument consists of a cylinder of suitable dimensions, which can be
held in the hand, in which a piston moves, having a rod passing through a cap
at one end, and furnished with a handle by which it can be withdrawn to the
required position.
A strong spring is situated at the back of the piston tending to force it to
the end of the cylinder when the rod is released. The piston is held back by
means of a spring pawl engaging with a rack or ratchet teeth on the rod so that

puned, until the pawi 19
released.
The putty is fed to the cylinder in front of the piston, which when released
forces the material in a regular manner out of a suitably formed opening in the
end cap of the cylinder, so that as the instrument is moved along the edge of the
window, the putty is laid in proper position in an even manuer.
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet of drawings in which
Fig. 1 and 2 are elevations of the complete instrument, taken at right angles to
each other,
Fig. 3 is a vertical section of the end of the cylinder through which the putty
emerges when the instrument is in use,
Fig. 4 is an end view of the same end of the cylinder or cap, and Fig. 5 is a
cross section.
The cylinder A is furnished at its upper end with a screwed cap B through
which the square piston rod C, carrying the piston or plunger c at its end, passes,
the cap having a similarly formed aperture to prevent the said piston rod turning.
At the back of the piston or plunger c is placed the spiral spring D which
forces it towards the lower end of the cylinder, on which is placed the cap E
having an aperture e towards one side, the cap being of a somewhat conical form,
or sloping so that it can be moved along the glass in an even and accurate manner.
The putty is placed between the piston and the said cap, the latter being removed
for that purpose and emerges from the aperture e. A device for smoothing or
moulding the putty as it proceeds from the aperture, or after it has been laid on
roughly, consists of a hinged plate F, fitting the top of the cap, which can be
turned back when not in use, or fixed when required by means of a small button f
or other simple device.
This hinged plate is formed with an extension f¹ at its end projecting at about
right angles and approximately parallel to the other side of the cap or at a slight
angle to it, which projecting plate smoothes or moulds the putty as the instrument
is moved along it.
To retain the piston rod in the required position after it has been pulled back
against the force of the spring by means of the handle C', ratchet teeth c' are
formed on the rod, with which engages pawl G hinged to the cylinder, and
furnished with a spring g which presses it on the rod.
When the putty is to be applied after the instrument has been charged, the pawl
is pressed back allowing the spring to act and force the putty out of the aperture,
the flow being stopped immediately the pawl is allowed to fall. The instrument is
held in the hand and moved rapidly up the glass, the tip of the nozzle pressing
into the window rebates, the bed of putty being regulated in thickness by pressing
the nozzle diagonally.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
(1.) A puttying device consisting of a cylinder charged with the material,
having a nozzle at which it issues, a piston with a spring forcing the putty out of
the nozzle at the required speed and means for withdrawing the said piston and
retaining it against the force of the spring, allowing it to be released when required,
substantially as described.
(2.) In a puttying device the combination of a cylinder containing the material,
having a nozzle through which it issues, with a piston, piston rod, spring forcing
the piston towards the nozzle and pawl engaging with ratchet teeth on the said
piston rod and retaining it in withdrawn position, substantially as and for the
purposes specified.
(3.) In a puttying device, the combination of a cylinder having a screwed cap
at each end, one forming a nozzle through which the putty can issue and the

page_text: other retaining the supplying mechanism, with a plunger, rod, spring and pawl,
the latter engaging with ratchet teeth on the rod, the whole constructed sub-
stantially as described, and for the purposes specified.
(4.) In a device of the kind described, in which a plunger works in a cylinder,
containing putty, and is operated by a spring, a conical cap forming a nozzle
screwed on the end of the cylinder, having an aperture through which the putty
is forced, and furnished with a projecting plate for shaping or moulding the
putty substantially as described.
