Improvements in Inking Pads.
I, HERMAN BAUMGARTEN, of No. 525, 7th Street, Washington D.C., U.S. of
America, Rubber Stamp Manufacturer, 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 inking pads, and particularly to means for preserving,
and lengthening the life or usefulness of rubber stamp inking pads.
The prime object of the invention is to provide a holder for inking pads and
for a series of cloth covers, whereby the latter may be removed, one or more at
a time, from the pad and leave the remaining cover or covers in proper position
on the pad, without removing the pad or separating the parts of the holder.
A further object of the invention is to provide a locking plate located within
the pad ring to lock the pad and one or more pad covers in the ring, without
employing set screws, springs, or clamps; said plate being adapted to be locsened,
yet held within the ring, to permit the removal of one or more of said covers
from the surface of the pad, through the top of the ring.
It is well known that to preserve the life or usefulness of inking pads, they
have to be provided with detachable covers to receive the impact of the stamp,
Such covers are usually held in place by set screws, springs or clamps, and the
pad and covers removed or dislocated in order to dispense with the top or worn
cover. The removal of one or more covers renders the holder difficult of adjust-
ment so as to hold the remaining covers smooth and tight across the top of the
pad, thus requiring great care, and often special tools to put the device in proper
condition for use.
It is to obviate these difficulties and overcome such disadvantages, and to
provide a pad holder that can be expeditiously and conveniently operated, that
my invention is intended.
Referring to the drawings:-
Figure 1 is a top plan view of my holder with pad and pad covers in place.
Figure 2 is a bottom plan view of the pad ring.
Figure 3 is a plan view of the washer plate.
Figure 4 is an enlarged section on the line - Figure 1.
Figure 5 is an inverted perspective view of the locking plate of Figure 4.
Figure 6 is an edge view of a modified form of locking plate.
Like numeral references denote like parts in the drawings.
The inking pad 1, is of the usual material, and of circular form somewhat
smaller than the ring 2, which holds it.
The pad holding ring 2, has a curved top rim 3, which forms an interior
cavity 4, and the edge thereof depends to form a nipping circular lip 5. The
bottom of the ring has a series of projections or lugs 6, and a finger opening or
notch is made in the rim 3, through which to grasp the cloth covers 3 for
removal.
The washer plate 8 forms a bearing surface for the locking plate 10. This

page_text: washer is provided with an edge notch or cut out 9, to permit its being inserted
under the lugs G.
The locking plate 10, has a series of slots or notches 11. and a series of cam
flanges 12, projecting from the periphery of the plate at right angles to the
inner surface of the same. The deepest end of each flange is at one side of each
notch, and the other end of each flange terminates flush or nearly so with the
inner face, of the plate at the opposite side of each notch so that the latter
separate the flanges.
The inner face of the plate 10, is provided with a hand piece 13, for turning
the plate.
In the modification shown in Figure 6, the locking plate 14, is made thicker
and without cam flanges, but in place of the latter, peripheral grooves 15, are
provided, which are engaged by suitable projections from the pad ring, and the
said plate is turned by the lugs 16, to lock the plate to the ring.
The parts are assembled, and the pad 1, and one or more covers 3ª, secured: in
the ring, by placing the washer plate 8, against the pad and the edge of the
cloth covers, inserting the locking plate and turning it on the lugs 6, which
tightens the said washer upon the pad and the covers and forces the edges of
the latter against the lip 5, leaving the extreme edge of the covers in the cavity 4,
and the body of the covers stretched tight across the pad.
One or more cloths or covers may be removed without dislodging or otherwise
interfering with the pad or remaining, covers, by simply loosening the locking
plate sufficient to permit a cloth or cloths to be pulled out of the ring by
grasping the edge of the cloth through the finger notch, then the locking plate
is tightened upon the remaining cloth or cloths.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:-
1-A holder for inking pads and pad covers, comprising a ring having a
finger notch through which the covers may be grasped for removal, lugs
or projections on the ring, and a locking plate fitting the ring and engaging
the said lugs to adjustably hold the pad and covers in the ring, as herein set
forth.
2-A pad cover holder comprising a ring having lugs, and a plate in the
ring having cams to engage the said lugs, and lock covers of various number
in the ring, as herein set forth.
3-A pad and pad cover holder comprising a notched ring having inward
projections, and a notched plate in the ring provided with cams adapted to be
turned on said projections to lock with the ring, as herein set forth.
4-A pad and pad cover holder comprising a ring having a finger notch upon
one edge, a locking plate having notches, and cam flanges at the periphery of
the plate adapted to be turned on said projections, for the purpose set forth.
5 In a pad and pad cover holder for hand stamps, the combination, with a
ring having a curved top rim forming an interior cavity and a nipping lip,
a finger notch in the rim, and lugs on the bottom of the ring, of a locking
plate having cams separated by notches in the periphery of the plate, a hand
piece on the plate, and a washier held against the pad and the covers and the
latter against said lip by the said cams engaging the said lugs, substantially
as set forth.
6 A pad and pad cover holder comprising a ring having lugs, and a locking
plate in the ring having cams terminating in notches and engaging the lugs
to hold pads of varying thickness and covers of various numbers in the ring as
set forth.
The combination of a holder, an inking pad carried in the holder, a cover
for said pad comprising two or more separate layers, and means carried in and

page_text: by said holder to hold the layers on the pad and to permit the outermost layer
to be removed intact without removing the pad or the remaining layer or layers,
and without disconnecting or removing the said means from the holder, as
herein set forth.
