the centre of its lower side projects a spindle. The under side of each
wheel or disc has a hollow formed within the circle of its peripheral
projections, and the cells of each wheel or disc are open at each ond and
on the outer side, also on the inner side below the line of the lower
surface of the body of the wheel or disc. The said wheels or discs are
placed in a horizontal position (and as near cach other as they can be
without being in contact with each other) upon a plain surface on the
upper side of the base of the hand stamp through which the spindle of
cach has its bearings. A sliding bar is placed in a horizontal position
under the day and month wheels or discs and within a groove in the
upper side of the base, a wedge being arranged to operate across the
peripheral line of both wheels or discs.

A, B, are two rotary wheels or discs. One wheel or disc A has on and
around its periphery a series of, say, twelve cells a, a, a, formed by
peripheral projections a¹, a¹, a', which extend below the lower side of the
body of the wheel or disc, their inner edge projecting inward under the
same. The part a³ of cach, which is on the inner side of the peripheral
line as, has on each side a lateral projection a', a', Figure 11, forming
shoulders on a line with the face of the periplicry to support the type in
a vertical position within its cells. On its upper side it has formed
thereon or applied thereto an index dial a³, in which are inscribed
opposite the cells in consecutive order the names of the months; from
the centre of its lower side projects a spindle a. The other wheel or
disc B has on and around its periphery a series of thirty-one cells b, b, b,
formed by the peripheral projections b¹, b', b¹, which extend below the
lower side of the body of the wheel or disc, their inner edge projecting
inward under the same; the part 2 of each, which is on the inner side
of the peripheral line, has on each side a lateral projection b', ',

page_text: Figure 10, forming shoulders on a line with the face of the periphery b³
to support the type in a vertical position within its cells; the part 6 of
cach of the projections forms a ratchet. On its upper side it has
formed thereon or applied thereto an index dial ³, on which aro
inscribed opposite the cells in consecutivo order the numbers of the
days, and from the centre of its lower side projects a spindle 6º. The
under side of each wheel or disc has a hollow area formed within the
circle of its peripheral projections, and the cells of each wheel or disc
are open at each end and on the outer side, also on the inner sido below
the line of the lower surface of the body of the wheel or disc. The said
wheels or discs are placed in a horizontal position (and near to cach
other without being in contact) upon a plain surface on the upper side
of the base C of the hand stamp, through which the spindle of each has
its bearings. D is the sliding bar, with slots d and d', wedge &ª³,
studs d³, d³, and ³, friction spring do, and finger piece d", in combination
with the lever E, with slot e, and stud cand e combined with the
paul Fattached to stud e', and with the spring G attached to the
stud e. The sliding bar is placed in a horizontal position under the
wheels or discs A and B, and within a longitudinal groove C in the upper
sides of the base C, the spindle aª operating through the slot d, and the
spindle b through the slot d', the wedge being situated on the part
thereof which operates across the peripheral line of both wheels or
discs A and B, and in such a position that it operates through the lower
part of the cell of each wheel or disc which is under the mortise of the
inverted caso M and of the die T; the studs d', d, and d³ are situated
on the part thereof which operates under wheel or disc B, stud d³ being
placed in such a position that when the sliding bar is being pulled
outward it comes in contact with the ratchet of wheel or disc B to
stop the momentum of the latter, and the studs d' and d³ being placed
in such a position that the lever E which lies horizontally across the
sliding bar and under and across the centre of the wheel or disc B lics
between them. Said lever E is at one end attached to the base C by
the pivot c³, which projects from its under side and fits in the hole c'
of the base C, the spindle 6º operating through the slot e, the paul F
at the other end (being pushed outward by the spring G prossing
against its inner sido) operating against the ratchet of wheel or
disc B.
The apparatus further consists of the tannat TT the

page_text: zontal position on the lower side of the base C, the latter having for the
purpose a hollow under side with a plain level surface. The tappet
is at one end attached to the spindle 6º, the other end thereof at cach
revolution of the wheel or disc B comes in contact with the ratchet
wheel or disc I (which is attached to the lower end of the spindle aº)
communicating motion from wheel or disc B to wheel or disc A. The
bent spring J is at one end fixed to the baso C, the other end having
a bulb j operates against the ratchet wheel or disc I to stop tho
momentum of the wheel or disc A altogether, as shown in Figures 3 and 4
of the Drawings.
The type used in combination with this Invention are known as
logotype, though other type may be used instead, the letter type K
representing the names of the months are placed in a vertical position
and in consecutive order into the cells a, a, a, of wheel or disc A, and
the figure type L representing the numbers of the days are placed
in a vertical position in consecutive order into the cells b, b, b, of wheel
or disc B. An independent inverted case M is employed, the plan
outline of which conforms to that of the basc C; its interior is divided
into two circular communicating chambers mand m³, as indicated by
the dotted lines m² and m³ in Figure 6 of tho Drawings, the chamber m
being of the same size as wheel or disc A, and the chamber m' being
of the same size as wheel or disc B. At the intersection of its chambers
m and m³ it has a mortise m* through its upper side, said mortise m*
being directly above the cell of each wheel or disc which is the nearest
each other, and into which the wedge d² of the sliding bar D operates
for the purpose of lifting the type.
On the application of the inverted case M to the upper side of the
base the wheel or disc A enters into the chamber m, and wheel or
disc B enters into the chamber m³, thus securely enclosing all the parts
which are placed upon the base C, the chambers serving to keep the
type within the cells, the latter being open on the outer side. The
inverted case M is attached or secured to the base C by screws passing
from the under side of the base C, upward through the holes c², c², and
screwed into the threaded holes m³, m³, of the inverted case C, or by
other suitable means. On the upper side the case has a perforation m³
over each wheel or disc, cach of which is situated in such a position
that when the type in any one of the cells of the wheel or disc which
is under the perforation is under or within the mortise m³, one of the

page_text: inscriptions on the index dial on the wheel or disc will be within the
area of the perforation through which it will be scen.
In combination with this arrangement the series of the type in cach
wheel or disc is placed in such a relation to the series of the inscription
on the index dial thercon that the type under or within the mortise m*, i
and the inscription seen through the perforation m', will be in wheel
or disc A the same in name, and in wheel or disc B the same in number.
The type N representing the number of the year is fixed into the rear
side of the mortise m* of the case M resting upon the upper surface of
the wheel or disc B.
A separable ribbon saddle O is employed for the purpose of carrying
and operating the inking ribbon Q, consisting of the plato o which has
at each end a cylindrical chamber o', o', for the reception of the ribbon
spindles P, P, around which is rolled the inking ribbon Q so as to
stretch from one to the other. The spindles consist of two cylindrical ·
tubes, each of which has at one end a head p with a slot p', and at the
other end a washer and pin p², the end of each which has the washer
and pin has a friction spring R for the purpose of holding the ribbon
taut. Both spindles have their bearings through the ends of the
chambers in the usual manner of other ribbon stamps.
In combination with the tubular spindles P, P, is used a key S con-
sisting of a rod with a finger piece s at one end, and at a point near the
finger piece two opposite pins or studs 8', 8', which fit into the slot p' of
the head p, the rod fitting into the tube, by means of which arrange-
ment the spindle only into which the key is inserted operates the ribbon,
the latter rotating always in the direction of the spindle containing the
key, which should remain within the same spindle until the rotating
part of the ribbon is wholly transferred from one spindle to the other.
Through the centre of the plate o is a mortise o² for the occupation of
the dic T, the latter being held therein by a dovetail, and having a
mortise of the same shape as the mortise m of the inverted caso M.
The dic T and the ribbon saddle O are combined with the inverted
casc M. The latter has on the part of its upper surface, which is under
the padded pressing block U, and which contains the mortise m', a
transverse groove m³, into which are placed the dic and the ribbon saddle.
The dic is placed in such a position that its mortise is directly above
the mortise of the inverted case, in which position it is held by a
dovetail, or in other suitable manner within the mortise o of the ribbon

page_text: "
saddle, the rear edge of the latter being held by a dovetail, or in other
suitable manner within the groove, and the front edge thereof being
held therein by a sliding catch V operating within a longitudinal
groove m in the upper surface of the inverted case in front of the
groove m³, within which it is held by a dovetail, or in other suitable
manner, and made operative by the use of a spring W, one end of which
bears against a projection of the inverted case, and the other against a
projection of the sliding catch, pushing the latter against the front
edge of the ribbon saddle, as shown in Figures 2, 4, and 6 of the
Drawings.
In the apparatus the stock or arm X' is attached to the lugs c', c¹, of
the case C by a hinge y, upon which it swings, as shown by Figuro 2 of the
Drawings, and by a pin or boltz and a spring ¹ fixed into and operating
within one of the lugs c' and against the stock or arm locking the latter,
as shown in Figures 1, 2, 4, and 5 of the Drawings. The stock or
arm X' terminates at its forward end in the block or head c³, through
which the plunger spindle c' operates. To the lower end of the latter
is attached the padded pressing block U, which is so arranged as to be
directly over the mortise m* of the inverted case M. The base C has
on its under side under the lugs c', c', a type chamber c³ with a sliding
lid operating in a dovetail, as shown in Figures 3 and 4 of the
Drawings.
To operate the apparatus pull the sliding bar D outward; the wedge d
will then be drawn out of the cells a and b under the mortise m¹ of the
inverted case M, and the mortise t of the die T allowing the type K and
L to gravitate from the mortise into the cells, its studs d will operate the
lever E and the paul F, and the spring G acting against the ratchet b
of the wheel or disc B will operate the latter, carrying the next cell
under the mortise of the dic, the stud d' acting against the ratchet bª of
the wheel or disc B, stopping its momentum at the point when the cell
is under the mortise. Then by pushing the sliding bar inward the
wedge ď² lifts the type upon its inclined plane to the level plane ď³ upon
which the type rests, the face of the latter being on a level with the face
of the die, as shown in Figures 4 and 12 of the Drawings. At the same
time the stud d' will operate the lever E to carry the paul F back behind
the next of the ratchets of the wheel or disc B. Each outward and
inward operation of the sliding bar changes the type in the mortise of
the die carried by the wheel or disc B, and cach thirty-two outward and
