page_text: To properly guide the valve, it is provided with a downwardly extending stem t
which passes through the central orifice of the spider e. A spiral spring f is inter-
posed between the spider and valve to hold the latter in its closed position.
The hereinbefore described flange 6" and tube t, form an annular cup surrounding
said tube, and in this cup is secured a swab or brush composed of felt, or
other suitable material adapted to spread over the pad the ink issuing from the
tube t.
In using the described inker, it is to be placed in an inverted position upon the
pad to be inked. The bearing of the outer end of the stem d' upon the pad pushes
the valve d into its open position, and thus allows the ink to escape through the
tube t. Then, by wiping the pad with the inker inverted as aforesaid, the swab h
spreads the ink over the pad. As soon as the inker is removed from the pad
the valve d is automatically closed by the spring f.
When the inker is to be used on pads connected to the stamp, as is the case with
spring stamps, where the pad is not accessible by an inker of the form shown in
Fig. 1 of the drawing the fount R is provided with a spout R', which terminates
with a lateral projection to which the discharge tube t, swab h and valve dis
connected combined and operating similar to the corresponding parts shown in Fig. 1
of the drawing.
My correspondents do not wish to be limited specifically to the use of the spiral
spring fas it is obvious that other forms of springs may be employed for the same
purpose. One of said modifications is illustrated in Fig. 5 of the drawing, in which
the spring fis formed of a leaf or plate of steel, or other suitable spring metal,
bowed at its central portion and secured at one end to the underside of the disc c
and supporting upon its opposite end the valve d.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondents, and in what manner the
same is to be performed I declare that what I claim is :-
1. A pad-inker consisting of an ink-fount provided with a discharge tube in one
end thereof a valve on the inner end of said tube and provided with a stem normally
projecting from the outer end of the tube a spring holding the valve in its closed
position a cup surrounding the discharge-tube and a swab secured in said cup as set
forth and shown.
2. As an improved article of manufacture a pad-inker composed of the fount R
provided with the removable stopper a in its bottom the ring b secured to the upper
end of said fount and formed with the inward offset b¹ and upward flange 6 the
disc c secured to the said offset and formed with the upwardly extending tube t the
valve d seated on the under side of the disc and provided with the stem d' extending
through the tube t the spider e attached to the ring 6 the stem t¹¹ extending from
the valve through the said spider the spiral spring f interposed between the said
spider and valve and the swab h seated upon the disc c and confined thereon by the
tube t and flange 6" substantially as described and shown.
