Improvements in Type-belts for use in Time-dating Stamps and for
similar purposes.
I, HENRY HARRIS LAKE of the firm of Haseltine Lake & Co. Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 type carrying belts as hereinafter described and shown
in the accompanying drawing in which,
Figure 1 is a face view of the belt,
Figure 2 a view of the opposite, or inner side of the belt,
Figure 3 an edge view of the belt, and,
Figure 4, a view, upon an enlarged scale, showing a section of the belt in
longitudinal section.
The same letters of reference denote the same parts.
One object of this invention is to provide an inarticulated belt, or belt made in a
continuous piece, capable of being moved more evenly and with more certainty
than the belts hithe used. Another object is to provide a type-carrying belt
that shall, in its m nt, cause the types to come successively into position for
use with more precand regularity than the types of the ordinary type-carrying
belt. The improvement is especially adapted to rubber type-belts.
One feature in the construction of the belt is the making of the same in parts:
the rubber type are mounted upon a continuous strip of a substance such as a
textile fabric less liable to stretch, and less liable to crack than is rubber.
Another feature is the separation of the types so that they are substantially
disconnected from each other thereby enabling the belt, in its use, to be turned
more or less sharply around angular bearings without straining the projections of
which the types respectively are parts. An additional feature is the making of
the projections, which are used upon the inner side of the strip to insure the
proper movement of the belt, integral with the material upon the outer side of
the strip.
The invention is more fully carried out when the union between the projections
and material is accomplished by extending the material through openings in the
strip, and, when the improvement is carried out to its fullest extent, the material is
extended through the meshes of the textile fabric of which the strip is preferably
composed, and the projections upon the inner side of the fabric are respectively
integral with the types upon the outer side of the fabric.
I do not wish to be restricted to a belt of any particular dimensions, for, while
this belt is particularly useful in contracted spaces, it can, so far as some at least
of its features are concerned, be made of almost any size and used accordingly.
Neither do I wish to be confined to a textile fabric in the construction of the strip,
so long as the material employed for the strip is sufficiently flexible, to serve as a
belt and adapted to be provided with the projections upon its inner side: nor, to
rubber in the formation of the types and of the projections, provided the substance
used is adapted for printing, and the types are separated from each other upon the
belt, or the belt is provided with the projections upon its inner side.
It is preferable, however, to use a textile fabric for the strip, and to separate the
types from each other upon the strip, and to make the types and their corresponding

page_text: projections respectively integral, and of rubber. For thereby a very desirable belt
is obtained for use in mechanisms in which exactness of movement is essential. A
time-dating stamp being a mechanism to which the present improvement is especially
adapted.
A represents a strip of textile fabric. B B B represent the types upon the outer
side of the strip. CCC, represent the projections upon the inner side of the strip.
The bodies of the type, can, in shape, be varied to suit the size and style of the
type, and they can be constructed to form, or be provided with, any types or
characters or other parts which it is desired to have applied to the belt and to be
brought into use in its movement. The projections upon the inner side of the belt
may also be variously shaped so long as they are respectively opposite the types,
and so long as they shall properly coact with the bearings over which the belt is
worked in its use. The projections C, enable the belt to be operated after the
manner of a sprocket-wheel belt. The separation of the types A, enable the types,
as they in the movement of the belt come into position for use, to be supported upon
flat surfaces and the belt, at points between the types respectively, to be bent more
or less sharply over or around bearings more or less angular. By this means the
belt is adapted for being moved with great regularity and surely and, at the same
time, in a manner not calculated to endanger the integrity of the belt. In Figure 3
the broken lines, D, indicate a mode in which the belt can be bent at points
between the types. The belt shown is especially adapted to a time-dating stamp.
It renders it feasible to employ a comparatively compact mechanism for that
purpose, and it enables two or more of the belts to be used upon the same shaft in
perfect alignment with each other.
An additional feature of the belt is the separatio.
projections C. These projections preferably not only
with each other but they preferably are also made with
lateral extension upon the inner side of the strip or band
Having now particularly described and ascertained th
tion and in what manner the same is to be performed
my foreign correspondent, I declare that what I claim ir
from each other of the
no direct counection
thing like a fillet or
of the said inven-
communicated to me by
First. A type-carrying belt having its types upon the outer side, and projections
upon the inner side, of a strip said types and projections being respectively opposite
each other, and said types, and also said projections, being substantially spaced
apart from each other upon the said strip substantially as described.
Second. A type-carrying-belt having its types upon the outer side, and projections
upon the inner side, of a strip, the said types and projections being respectively
opposite each other, and integral, and said types, and also said projections, being
spaced apart from each other upon said strip substantially as described.
Third. A rubber-type belt having its types upon the outer side, and projections
upon the inner side of a strip of textile fabric said types and projections respectively
being united by extending the material, of which the types and projections are
formed, through the meshes in the said strip, substantially as described.
Fourth. A rubber-type belt having its types upon the outer side, and projections
upon the inner side of a strip of textile fabric, the said types, and projections being
substantially spaced apart from each other upon the said strip, and the spaces
between said projections being respectively opposite he spaces between said types,
substantially as described.
