COMPANY, United States of America.
1, JAMES GRIEVE LORRAIN, of Norfolk House, Norfolk Street, Strand,
London, W.C., Chartered Patent Agent, do hereby declare the nature of this
invention to be as follows:
My invention relates particularly to platen carriages of typewriters, to the ways
upon which said carriages reciprocate, and to mechanism for guiding the inking
ribbon. The object of the invention is to produce a platen carriage, ways for said
carriage,, and guides of the inking ribbon, all of which may be readily removed
from and replaced upon the machine, to the end that access may be readily had³tò
the parts of the machine located beneath the carriage.
In the.accompanying drawings:
Figure 1 is a plan of a portion of a typewriter embodying my invention.
Figure 2 is a front elevation.
Figure 3 is a vertical section in line a-b of Figure 1.
Figure 4. is a vertical section in line a-c of Figure 1.
A is the upper portion of the frame of the machine. This may be of any well
known form. A is a central opening through which the well known type-bars
rise to reach the platen. A, A² are openings in said frame through which the
inking ribbon, A³, passes. A', A' are parallel dove-tail grooves extending from
the front of the upper portion of the frame, A, rearward through the latter almost
to the rear of said frame. B, B, are dove-tail bars accurately fitted into said
grooves, but loosely enough to permit longitudinal reciprocation therein. At any
couvenient point in each of said bars a binding screw, B', extends through said
bar and is adapted to be pressed against the bottom of the groove, A', in which
said bar is located. By means of said screws, said bars may be immovably bound
in said grooves.
C, C are parallel rails each extending from one of the bars, B, to the other and

platen to the carriage, for this is well understood by those familiar with this-art.
E, E are ribbon guides extending from.onec rail, C, to the other at each side of
the centre..of the opening, A. Said:guides extend beneath the carriage, D; and
ae.attached.rigidly to the said rails, C.. To provide for the release of the ribbon
when the carriage rails are removed;.1 have provided for temporarily, forming a
gap at the middle of each of said: supports. To this end each of said supports
consists of two rods, E, approaching each other from the opposite side rails and 'a
loose sleeve, E., surrounding said rods and adapted to be moved longitudinally

the carriage rails are to be removed, the sleeves, E, are slipped toward one of the
rails until said gap is exposed, and then the inking ribbon is moved downward
through said gaps. Then said guides and said rails are free to be lifted away.

A communication from abroad by THE REMINGTON-SHOLES TYPEWRITER
COMPANY, United States of America.
I, JAMES GRIEVE LORRAIN, of Norfolk House, Norfolk Street, Strand,
London, W.C., in the County of Middlesex, Chartered Patent Agent, 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 particularly to platen carriages of type-writers, to the
ways upon which said carriages reciprocate, and to mechanism for guiding the
inking ribbon. The object of the invention is to produce a platen carriage,
ways for said carriage, and guides of the inking ribbon, all of which may be readily
removed from and replaced upon the machine, to the end that access may be
readily had to the parts of the machine located beneath the carriage.
In the drawings left with Provisional Specification,
Fig. 1 is a plan of a portion of a type-writer embodying my invention.
Fig. 2 is a front elevation.
Fig. 3 is a vertical section in line ab of Fig. 1.
Fig. 4 is a vertical section in line a- of Fig. 1.
A is the upper portion of the frame of the machine. This may be of any well
known form. A is the central opening through which the well known type-bars
rise to reach the platen. A³, A³ are openings in said frame through which the
inking ribbon, A', passes. A', A' are parallel dove-tail grooves extending from
the front of the upper portion of the frame, A, rearward through the latter almost
to the rear of said frame. B, B, are dovetail bars accurately fitted into said
grooves, but loosely enough to permit longitudinal reciprocation therein.
At any
convenient point in each of said bars a binding screw, B', extends through said
bar and is adapted to be pressed against the bottom of the groove, A', in which
said bar is located. By means of said screws, said bars may be immovably bound
in said grooves.
C, C are parallel rails each extending from one of the bars, B, to the other and
having there ends secured to said bars by any suitable means.
For this purpose, I prefer to apply a short cross-piece, C, at each end of said
rail between the latter and the adjacent bar, and attach said cross pieces to said bar
by means of screws, c¹.
D is the platen carriage. This is arranged to reciprocate upon the rails, C, in
any suitable manner. The drawings show the opposing faces of said rails provided
with tongues, c, extending into grooves, d, in the edges of the carriage.
I deem it unnecessary to illustrate and describe the manner of applying the
platen to the carriage, for this is well understood by those familiar with this art.
E, E are ribbon guides extending from one rail, C, to the other at each side of
the centre of the opening, A. Said guides extend beneath the carriage, D, and
are attached rigidly to the said rails, C. To provide for the release of the ribbon
when the carriage rails are removed, I have provided for temporarily forming a

page_text: gap at the middle of each of said supports. To this end each of said supports
consists of two rods, E¹, approaching each other from the opposite side rails and a
loose sleeve, E, surrounding said rods and adapted to be moved longitudinally
upon said rods to uncover the gap between the adjacent ends of said rods. When
the carriage rails are to be removed, the sleeves, E³, are slipped toward one of the
rails until said gap is exposed, and then the inking ribbon is moved downward
through said gaps. Then said guides and said rails are free to be lifted away.
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 typewriter, the combination with the frame, A, of bars, B, detachably
secured to said frame, rails, C, secured to said bars, and a platen carriage, D, and
separable ribbon-supports applied to said rails, substantially as set forth.
2. In a typewriter, the combination with the frame, A, the carriage rails, C,
and suitable removable supports to which said rails are attached, of ribbon
supports, E, consisting of rods, E¹, attached to said rails, and sleeves, E, loosely
surrounding said rods, substantially as set forth.
Dated this 16th day of July 1895.
