York.
1, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in
the County of Lancaster, and 323, High Holborn, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
The invention relates to type-writer having the type fixed to levers called type bars
pivoted in a circle, and swinging inward and upward against the paper, held on a
cylinder or platten roll on a movable carriage, the carriage being moved by a spring,
and its movement being regulated by a rack hinged to the carriage in conjunction
with two dogs or catcher, attached to a pivoted frame, one attached rigidly, and one
pivoted to the frame.
The invention partly consists in providing means for more readily adjusting the
movement of the pivoted dog, and in facilitating the lifting of the rack away from
contact with dogs.
In this machine the carriage is guided by grooved wheels resting on the flattened
sides of the back hinge rod, pivoted to projection on the top plate and supported in
front by a wheel.
The rack frame to which is attached the spacing rack, is hinged to the
carriage frame by the hollow hinge pin or bushing, the hinge rod passing through
the bushing, the hole in the bushing being large enough to allow of the rod to
pass through without touching it, the carriage being wholly guided by the wheels
ind the hinge rod.
When the carriage is at rest, the rack is held

page_text: by a spring, and into a position far enough in advance of the rigid dog to engage a
tooth on the rack on its return to its normal position, to allow a movement of the
carriage equal to the letter space desired.
To allow of the carriage being moved to right in position for beginning a line
without raising the rack from contact with the loose dog, the loose dog is made in
two parts, the upper portion or dog proper, and the lower portion jointed by the
knuckle joint made in such form as to admit of its tipping one way to admit of
the rack passing over it in one direction, without being raised from contact with it.
The loose dog is held in its normal position against the stop by a spring.
The entire dog is held away from the stop and against the leather cushion, attached
to the adjustable stop by the spring, one end of the spring resting in a hole in the
rocker arm, the other end of the spring engaging with a hole in the lower portion of
the dog shown near its pivotal point.
The adjustable stop is attached to the rocking frame by the screw passing through
an opening in the stop and into the rocking frame, and is guided by a groove in the
rocking frame.
The stop is adjusted by the adjusting screws, threaded into the ends of the stop,
their ends abutting against the rocking frame. It will be readily seen that by the
means provided any wear on the parts may be counteracted, for the stop is adjusted
to give a proper position to the pivoted dog that it may move freely between the
teeth of the rack, and may be so adjusted that the carriage will move the distance
of one or more teeth on the rack at each vibration of the rocking frame, if
desired.
To facilitate the moving of a carriage on a type writer, the movement of which is
regulated by a rack hinged to the carriage, and a rigid and loose dog or pivoted dog
attached to a rocking frame, pivoted to a support.
A lever is attached to the rack frame so formed as to pass above the hinge rod and
under the carriage, its free end projecting above the carriage at the left of the cylinder,
and in front of the pivotal line of the cylinder.
By depressing the free end of the lever the rack is removed from contact with
the dogs and the carriage is free to be moved in either direction on the guide rod.
The lever is preferably made of round wire, and it is attached to the rack frame
by drilling into the end of the rack frame, inserting the wire, and holding it into
position by a set screw.
A lever may be attached to the rack frame in any other way at the left of the
carriage without departing from the spirit of the invention.
To avoid the sticking of the stop on the pivoted dog, and to leave only a small
surface to catch dust and dirt, the metal in the part of the dog is removed, leaving
only a small edge.
Another form of the adjusting stop may be used, if desired, attached to the
spacing rocker by a screw in the same manner as, before described, but with one
adjusting screw, which has an annular groove fittting into a notch in one end of
the stop.
The rocking frame is drilled and threaded to receive the thread part of the screw.
It is obvious that by turning the adjusting screw, the stop will be moved by the
annular groove engaging with the sides of the notch in the stop. The screw may be
used as a clamp screw to hold the stop in position when it has been properly adjusted
by the adjusting screw.

depressing any of the key levers except the upper and lower case levers 107 and 111,
the contact with the rack is changed from the pivoted to the rigid dog, and the
pivoted dog 65 is forced against the stop 123 by the spring 77, and into the position
shown in Figures 4 and 6 far enough in advance of the rigid dog to engage a tooth
on the rack 102 on its return to its normal position, to allow a movement of the
carriage equal to the letter space desired.
To allow of the carriage being moved to the right in position for beginning a line
without raising the rack from contact with the loose dog, the loose dog is made in two
parts, the upper portion or dog proper 65, and the lower portion 65, both being jointed
by the knuckle joint 42 shown in Figures 4 and 5, and in detail in Figures 7 to 11.
The dog is made in such form as to admit of its tipping one way to admit of the
rack passing over it in one direction, without being raised from contact with it.
The loose dog 65 is held in its normal position against the stop a shown in
Figures 4 and 6, and in detail in Figures 7 to 11, by the spring 78 shown in
Figures 4.
The entire dog is held away from the stop 6, (shown in Figures 2, 3 and 5) and
against the leather cushion 124 (shown in Figures 4, 14 and 17, and attached to the
adjustable stop 123) by the spring 77 shown in Figures 4 and 5, one end of the
spring resting in a hole in the rocker arm 166 at & shown in Figures 2, 4, and 6,
the other end of the spring engaging with a hole in the lower portion of the dog 65
shown at e, Figures 4 and 5 near its pivotal point 42.
The adjustable stop 123 is attached to the rocking frame 106 by the screw 23
passing through an opening in the stop 123, and into the rocking frame 166 as shown
in Figures 5 and 6, and the stop is guided by the groove e in the rocking frame 166.
shown in Figure 3.
The stop 123 is adjusted by the adjusting screws 561-56, shown in Figures 4, 5-
and 6, threaded into the ends of the stop 123, their ends abutting against the rocking.
frame 166, as shown in Figures 4, 5 and 6. It will be readily seen that by the means
provided, any wear on the parts may be counteracted, for the stop is adjusted to give
a proper position to the pivoted dog, that it may move freely between the teeth of the
rack, and may be so adjusted that the carriage will move the distance of one or more
teeth on the rack at each vibration of the rocking frame 166, if desired.
In a typewriter, the movement of which is regulated by a rack hinged to the
carriage, and by a rigid and loose dog, or pivoted dog attached to a rocking frame
pivoted to a support, the following arrangement may be employed to facilitate the
moving of the said carriage.
A lever 168 is attached to the rack frame 168 at g, and is so formed as to pass
above the hinge rod 2, and under the carriage 158, its free end projecting above the
carriage at the left of the cylinder, and in front of the pivotal line of the cylinder,
as shown in Figures 1 and 18.
By depressing the free end of the lever 108 the rack 102 is removed from contact'
with the dogs 64 and 65 and the carriage is free to be moved in either direction on
the guide rod 2.
The lever 168 is preferably made of round wire, and is attached to the rack
frame 168 by drilling a hole into the end of the rack frame 168, inserting the wire,
and holding it into position by a set screw f, as shown in Figures 1 and 22.
A lever may be attached to the rack frame in any other way at the left of the
carriage, without departing from the spirit of the invention.
To avoid the sticking of the stop a on the pivoted dog, and to leave only a small
surface to catch dust and dirt, the metal in the part 65 of the dog, is removed, as
shown at h, Figures 9, 10 and 11, leaving only a small edge at a.
In Figures 15, 16 and 17 there is shown another form of the adjusting stop 123.
It is attached to the spacing rocker 166 by a screw 23 in the same manner as before
described, but it has only one adjusting screw 56, which has an annular groove 3
(shown in Figures 16 and 17), fitting into a notch k, Figure 15 in one end of the
top 123

page_text: The rocking frame 166 being drilled and threaded to receive the thread part of the
screw 56, as shown in Figures 17, it is obvious that by turning the adjusting screw,
the stop will be moved by the annular groove 3, engaging with the sides of the
notch in the stop. The screw 23 may be used as a clamp screw to hold the stop in
position when it has been properly adjusted by the adjusting screw 56.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
1. In a typewriter having a movable carriage, a rack fixed to a frame hinged to
the carriage, and an escapement composed of a rigid and pivoted dog, a joint in the
pivoted dog between its pivotal point and its point of contact with the rack, substantially
as shown and described, and for the purpose specified.
2. The regulating of the movement of a carriage on a typewriter by the combina-
tion of a rack hinged to the carriage, and of a rigid and a pivoted dog, the pivoted
dog having a joint between its pivotal point and the point of contact with the rack,
substantially as shown and described.
3. In a type writer having a jointed dog such as described, the holding of the
jointed parts of the dog in position by means of stops formed on the joint, and of a
