Improvements in Marking or Numbering Machines.
JAMES DAVENPORT, Engineer, 15, Limes Grove, Lewisham, London, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in numbering or marking machines
rendering them especially applicable for the marking of linen, in steam and
other laundries, as a means of ready identification. In my invention I employ
a wheel or wheels on the periphery of which are raised figures or letters or other
signs, as is common in numbering machines, and I prefer to fix them at the end
of an arm the opposite end of which is pivoted to the body of the machine so
that by means of a rod & pedal or other contrivance the wheels are readily
brought into contact with the article it is desired to mark. The figures or signs
on the wheels are inked by means of a pad contained in a revolving holder, which
holder is, in its turn, contained in a frame & this frame by means of suitable
springs causes the pad to come into contact with the signs. The frame is pivoted
to the body of the machine in such a manner that the axle running through the
wheels, or other suitable contrivance, must come into contact with & displace
it before the wheels can fully descend, and the displacement is regulated &
controlled by the suitable shape of that portion of the frame which the said axles
come into contact with. The displacing of this frame moves the inked pad
from the signs and a notched wheel affixed to the underside of the actual holder
of the pad engages with a suitable projection and causes the said holder
to revolve a certain distance. Upon the wheels regaining their normal position
the pad resumes its position under the signs. The signs on the wheels are
brought into any desired position by means of thumb nuts connected to the wheels
by tubular connections.. The wheels are locked in any desired position by means
of small levers or other contrivances which engage, automatically or otherwise,
with suitably placed notches in the periphery of the thumb nuts. In order to
facilitate removal of pad from contact with signs I employ a bar or slide so fixed
and shaped that a slight displacement of the pad holder frame shall be caused
by it before any movement of the arın is effected. In order to prevent the ink
clogging the wheels I perforate them with suitably shaped holes, or I may make
the wheels skeleton.

This invention relates to improvements in numbering or marking machines,
rendering them especially applicable for the marking of linen in steam and
other laundries as a means of ready identification. In my invention I employ
a wheel or wheels on the periphery of which are raised figures or other signs as
is common in marking machines and I prefer to fix them at the end of an arm
the opposite end of which is pivotted to the body of the machine, so that by
means of a rod and pedal or other contrivance the wheels are readily brought
into contact with the article it is desired to mark. The figures or signs on the
wheels are inked by means of a pad contained in a revolving holder, which

pivotted to the body of the machine in such a manner that the axle running
through the wheels, or other suitable contrivance must come into contact with
and displace it before the wheels can fully descend and the displacement is
regulated and controlled by the suitable shape of that portion of the frame which
the said axles come into contact with. The displacing of this frame moves the
inked pad from the signs and a notched wheel affixed to the under side of the
actual holder of the pad engages with a suitable projection and causes the said
holder and pad to revolve a certain distance. Upon the wheels regaining their
normal position the pad resumes its position under the signs. The signs on the
wheels are brought into any desired position by means of thumb nuts connected
to the wheels by tubular connections. The wheels are locked by suitable
means.
In order to prevent the ink clogging the wheels I perforate them with suitably
shaped holes or I may make the wheels skeleton.
And in order that my said invention may be better understood I will now
proceed to describe the same with reference to the drawing accompanying this
specification in which Fig. 1 shews elevation of machine with type or signs raised.
Fig. 2 elevation with type or signs lowered as it would appear when in position
of marking. Figs. 3 to 7 shew details hereinafter referred to.
The same letters denote the same parts in all the views.
a shews wheels, with raised figures or other signs on their peripheries, these
figures or signs are marked b. The wheels a are carried by an arm c, the opposite
end of which is pivotted to the body d of the machine at e. f is a pedal rod for
bringing the wheels a down for marking, as in Figure 2. g is a spring for
carrying the arm c back when the pedal is released. The figures or signs are
inked by means of a pad h, this pad is revolved by means of a ratchet wheel i
attached to the underside of said pad, and a pawl j attached to the frame d of
the machine the wheel i and pawl j engage each time the arm c is brought
down, as shewn at Fig. 2. The pad his carried by a carrier & suspended at in
and kept normally in position against the type or sign b by springs n: but when
the arm e is brought down, this carrier k is swung back, as shewn at Figure 2,
owing to the pressure of the spindle of the wheels a on the curved part o. p
shews small wheels, each connected with a corresponding wheel a, these latter
wheels being mounted upon independent sleeves. By means of the wheels p, the
type wheels a may be set as desired. These wheels may be provided with slots
as shewn at Figs. 6 and 7, so that a lever, bar or other contrivance attached to
the machine may engage or disengage in these slots, to lock or unlock the wheels
as desired. Letters may be so arranged round the peripheries of the wheels
as to indicate the letter set to mark on the corresponding wheel a.
The wheels a are formed in skeleton shape, to prevent the ink from clogging
them.
The frame of the machine and the carrier k are shewn in plan without the
arm cat Fig. 3. The arm e is shown detached in elevation at Fig. 4 and in

page_text: I do not wish to confine myself to the precise details herein described and
shewn on the accompanying drawing as the same may be varied.
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:-
Marking and numbering machines constructed substantially as herein described
and shewn on the accompanying sheet of drawings.
