ALFRED SWEETSER 67 Croxted Road West Dulwich in the County of Surrey
Mechanical Engineer do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to produce a type writer in which the whole of
the letter or other document being printed can always be plainly seen by the
operator, without having to turn a cylinder, shift a carriage, or any other
movement; and at the same time the machine shall be extremely simple in
construction.
In carrying out my invention I employ a bed plate having a main slide, upon
this slide I fix pulleys, upon which an endless band is stretched, carrying the type.
The main slide is lettered and fitted with an auxillary slide with pointer, this auxillary
slide is fixed to one side of the aforesaid endless band, and is fitted with a locking
device, such as a spring bolt, so that it can be readily fixed to the main slide
opposite any of the aforesaid letters, by the aid of the aforesaid pointer and
suitable notches or holes in the main slide.
The lettering on the main slide and the type on the endless band are so arranged
in respect to each other, that when the auxillary slide is fixed to the main slide
opposite any particular letter, its corresponding type shall be in any prearranged
position, this position being opposite to the position on the paper where the
printed character is required to be much on the same principle as a mechanical,
or engine room telegraph. To allow the lettering on the main slide being shown
larger than the printed characters, or to bring other characters than those in
immediate use into position, the position of the auxillary slide on the aforesaid
endless band is made adjustable, by a spring bolt, the intermission of an excentric,
or its equivalent.
The paper carriage 1 form of a longitudinally slotted tube fitted with a rack and
pawl movement to feed it along, and suitable bearings for it to work in, such slotted
tube being fitted with an internal grooved roller, to hold and roll the paper
on, and such grooved roller is fitted with suitable pivots and milled head to
turn it by.
The operation of the machine is as follows-The auxillary slide being placed
opposite the letter the printed character of which is required to appear on the
paper, the auxillary slide is locked to the main slide, and the whole pressed
forward till the character is printed on the paper, it having been previously passed
from off the aforesaid internal roller, through the slot in the paper carriage, and
over a fixed cushion or stop. Upon the withdrawal of the main slide, an uninter-
rupted view of the printing will be obtained.
The type is inked by a roller, it being fixed to the bed plate of the machine by
a spring arm, and being pushed out of the way by the movement of the
main slide.
It will be obvious that instead of employing an endless type band, it could be
simply a band with a spring or weight, or its equivalent, to withdraw it; or there
might be one or more type wheels connected with the auxillary slide by a rack, or
band, or its equivalent.
Dated this Sixth day of November 1894.

Mechanical 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 :-
The object of this invention is, to produce a type-writer in which the whole of
the letter or other document being printed can always be plainly seen by the
operator, without having to turn a cylinder, shift a carriage, or any other
movement; and at the same time the machine shall be extremely simple in
construction.
In carrying out my invention I employ a bed plate having a main slide, upon
this slide I fix pulleys, upon which an endless band is stretched, carrying the type.
The main slide is lettered, and fitted with an auxillary slide with pointer, this
auxillary slide is fixed to one side of the aforesaid endless band, and is fitted with
a locking device, such as a spring bolt, so that it can be readily fixed to the main
slide opposite any of the aforesaid letters, by the aid of the aforesaid pointer, and
suitable notches or holes in the main slide.
The lettering on the main slide, and the type on the endless band are so arranged
in respect to each other, that when the auxillary slide is fixed to the main slide
opposite any particular letter, its corresponding type shall be in any prearranged
position, this position being opposite to the position on the paper where the
printed character is required to be-much on the same principle as a mechanical
or engine room telegraph. To allow the lettering on the main slide being shown
larger than the printed characters, or to bring other characters than those in
immediate use into position, the position of the auxillary slide on the aforesaid endless
band is made adjustable by a spring bolt, the intermission of an excentric or its
equivalent.
The paper carriage I form of a longitudinally slotted tube, fitted with a rack
and pawl movement to feed it along, and suitable bearings for it to work in, such
slotted tube being fitted with an internal grooved roller to hold and roll the
paper on, and such grooved roller is fitted with suitable pivots, and milled head to
turn it by.
The operation of the machine is as follows. The auxillary slide being placed
opposite the letters the printed character of which is required to appear on the
paper, the auxillary slide is locked to the main slide, and the whole pressed forward
till the character is printed on the paper, it having been previously passed from
off the aforesaid internal roller through the slot in the paper carriage, and over a
fixed cushion or stop. Upon the withdrawal of the main slide an uninterrupted view
of the printing will be obtained.
It will be obvious that, instead of employing an endless type band, it could be
simply a band with a spring or weight, or its equivalent to withdraw it; or there
might be one or more type wheels connected with the auxillary slide by a rack, or
band, or its equivalent.

In order that my invention may be clearly understood, reference may be made
to the accompanying drawing, in which Fig. 1 is a side elevation, and Fig. 2 is a
plan of a type writer made according to my invention. A, is the bed of the
machine; a, is the main slide; bb, are pulleys upon which the endless band, c,
stretched; d, is the auxillary slide; e e, the pointers; /, the connection to the
endless band c; g, is the key, and g', is a spring bolt to engage the notches or
rack h, for the purpose of pushing the main slide a, forward in the act of pointing;
i, and, are the upper and lower case type ranged alternately round the endless
band c, is an excentric connected to the key g, by turning which alters the

page_text: position of the main slide a, in respect to the type i, i¹, on the endless band c,
which brings the intermediate type into use, thus changing the case. B is the
paper carriage; k, the paper; 1, is the cushion or stop.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. The auxillary slide d, and the main slide a¹, working on the same horizontal
plane.
2. The excentric j, for altering the relative position of the main slide a, in
respect to the type on the endless band c.
3. The general construction, and arrangement of parts for the purposes set forth,
and illustrated by the accompanying drawing.
