PROVISIONAL SPECIFICATION.
Improvements in or applicable to Type-writers.
I, EDWARD TENNEY BOUSFIELD, of Bedford, in the County of Bedford,
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to type-writers of the Hammond class which have an inking-
ribbon interposed between the type and the paper which is to receive the impress
of the type, and has for its object to enable the operator to read the word last
printed without the necessity for shifting the paper clear of the inking-ribbon, which
operation involves loss of time, and sometimes considerable difficulty in readjusting
the paper to its proper position.
When applying my improvements to the well known "Hammond Type-writer,"
the guard-rim which supports and guides the inking-ribbon and also carries the
shield is made to vibrate instead of being firmly screwed in position as heretofore
and at the opposite side of the guard-rim from that which supports the inking-
ribbon, a lever is attached and extended backwards, its extremity being connected
by a link with the spacing key. At the end of each word when the spacing key is
used, the rim is rocked on the hinge, at the same time the ink-ribbon is lifted above
the word last printed in sight of the operator who has an opportunity of verifying
his work without hindrance or changing his position. The operator can at any
time lift the ink-ribbon independently of the spacing lever.

COMPLETE SPECIFICATION.
Improvements in or applicable to Type-writers.
I, EDWARD TENNEY BOUSFIELD, of Bedford, in the County of Bedford,
Engineer, 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 :-
My invention relates to type-writers of the "Hammond "class which have an
inking-ribbon interposed between the type and the paper which is to receive the
impress of the type, and has for its object to enable the operator to read the word
last printed without the necessity for shifting the paper clear of the inking-ribbon,
which operation involves loss of time, and sometimes considerable difficulty in
readjusting the paper to its proper position.
When applying my improvements to the well known "Hammond Type-writer,"
the guard-rim which supports and guides the inking-ribbon and also carries the
shield is made movable instead of being firmly screwed in position as heretofore and,
at the opposite side of the guard-rim from that which supports the inking-ribbon a
lever is attached and extended backwards, its extremity being connected by a link
with the spacing-key.
To enable my invention to be fully understood I will describe the same with
reference to the accompanying drawing, in which
Figure 1 is a perspective view of a Hammond Type-writer" provided with my
improvements; and,
Figure 2 is a section shewing the guard-rim and adjacent parts.
a indicates the base of the type-writer, and the guard-rim, which is carried upon

e, e being the spools for carrying the said ribbon.
fis the shield which is carried by the guard-rim band which is interposed between
the inking-ribbon and the paper to be operated upon.
is a hinge or joint by means of which the said guard-rim is connected to the
cylinder and which permits the said guard-rim to be oscillated or vibrated
relatively to the said cylinder. is a lever by means of which the said guard-rim
may be vibrated, and is a link connecting the said lever to the spacing-keyj of
the key-board.
The operation of the apparatus herein before described is as follows, that is to
say, during the ordinary working of the type-writer, the guard-rim rests upon the
top of the cylinder e, as indicated by full lines in Figure 2 should it be necessary
to inspect the word last written it is only necessary to oscillate the guard-rim upon
its hinge by depressing the lever h, as indicated by dotted lines in the said figure,
the said guard-rim being then in such a position that the last word can be seen.
This will be clearly understood by reference to Figure 1, where & indicates a sheet of
paper, the dotted lines upon which represent the printing thereon, and the portion /
of such dotted lines the last word or words written.
By connecting the lever to the spacing-key, as shewn, the guard-rim is lifted
at the completion of each word so that the operator can, if desired, examine the
same, this connection is not, however, necessary.
m, m are the studs around which the inking-ribbon passes, the said studs being,
as shewn, brought near to the pivot of the said guard-rim, at which point the
movement is less than at the front of the same, so that the said ribbon is not creased
or crumpled as would be the case if it passed directly from the spools over the front
of the guard-rim.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a type-writer in which the inking-ribbon conceals the last word or words
printed from view, mounting the guard or guide-rim over which the said ribbon
passes in such a manner that it may be moved with the ribbon in order to reveal
such word or words, substantially as described.
2. In a type-writer mounting the guard-rim in such a manner that it
rocked, substantially as, and for the purpose, described.
may be
3. In a type-writer having a movable guard-rim or guide for the inking-ribbon,
connecting the said guard-rim or guide to the spacing-key in such a manner that,
when the said key is depressed, the said guard-rim or guide will be moved, substan-
tially as, and for the purpose, described.
4. In a type-writer of the kind herein before described, mounting the pins, around
which the ribbon passes, on the rear of the guard-rim, substantially in the manner
and for the purpose described.
5. In a type-writer, the combination of the movable guard-rim or guide for the
ribbon and the lever for operating the same connected to the spacing-key, substan-
tially as, and for the purpose, set forth.
6. The adaptation to a type-writer of means substantially as hereinbefore
described and illustrated in the accompanying drawing for the purpose specified.
