page_text: F, is the upper and G, the lower supporting plate rigidly connected by the
post 34, and supported upon a suitable bed plate which also serves to support the
key-levers, the levers for raising the central anvil, the hammer arm and its
operating springs, &c., &c. The key levers, as 2, are supported on three concentric
ribs of which the shaft E, is the centre. These levers are all of the same size
and shape, and formed with an angular notch 7. At this edge they are fulcrumed
on the knife edge rib a. These levers act upon the stop pins 57, which in turn,
being raised, arrest the stop arm 21. The levers No. 13 and 14 which are used to
elevate the type anvil are fulcrumed on the rib 9, their rear ends resting below
the shaft E. The combined shuttle arm g, and stop arm 21 is rigidly mounted
upon the cylindrical sleeve T, which is adapted to fit on the shaft E, the screw t¹
in the plate I, through which, the shaft passes, secures the combined arm so that
it cannot be raised, but permits its rotary motion. The finger S, at the end of the
shuttle arm g,
is at a right angle with the arm and is of a width to fit into the
space between the bosom 0-w. At f, near the pivotal point, the arm is adapted
to receive the end of the driving levers c, c.
These levers c, c, are mounted on skeleton sleeves on the shafts B, B. Secured
to these shafts are the horizontal driver arms b, b, which extend over the key
levers 2. Springs, as 25, secured to these arms return them and the driving levers
to their normal position. Each vertical driving lever terminates in a finger "1
which engages the combined shuttle and stop arm at f.
The anvil which supports the type shuttle is composed of the circular segment H,
which is rigidly mounted upon the shaft E. This segment H, is so constructed
that it affords a solid and rigid backing for the shuttle on its face.
The shaft E, has its lower end bevelled and is provided with a groove V₁ into
which the screw V extends. By the action of V the shaft has a free vertical
motion but cannot be revolved. The spring U, resting in the notch u, serves to
retract the shaft and anvil to their normal position after having been elevated by
the levers 13 or 14. The face of the anvil is recessed at i, to lessen the bearing
surface.
The type shuttle W, is usually made of hard rubber, but may be of any suitable
material. I make it in several forms. In the forms as shown in Figures 3, 4, 5,
and 6 it consists of a curved strip having on its face the letters or characters to be
printed and provided on the back with clips which engage the anvil H, at its
circumference. The finger S, on the shuttle arm, serves to retain it in contact
with the anvil. In order to reduce the friction to its minimum, I spring the shuttle
so that it comes in contact with the anvil only at its extremities. This difference
in circumference is, however, very slight, aud when the finger S, engages the
shuttle it is hardly appreciable to the unassisted eye. In the forms as shown in
Figures 10 to 14 inclusive, the shuttle is provided at its back with a metal rib, w,
which is inserted in the rubber w' so as to be firmly united with it. The inner edge
of this rib is slightly bent or crimped so as to increase the firmness of its position in
the rubber. On the face at the point of contact with the shuttle arm finger S, is a
piece of metal, w³, to serve as a bearing, to lessen the wear at that point. The
segment H of the anvil is necessarily modified to adapt it to the form of shuttle.
The modification is confined to the face of the segment which is provided with the
slot adapted to receive the rib w*.
In Figure 16, is the lower and the upper half of the modified type anvil.
The lower section is firmly fastened to the shaft E, by the set screw e, the upper
section fits upon the shaft and is held in position by the thumb screw e.
The
stop y, secures correct registration between the two sections. The type finger S³ is
on the shortened shuttle arm g' and engages the type shuttle on its inner side by
the projections W, this type shuttle is constructed like W¹ except that the metal
rib has the projections W' at the centre and the retaining clip WⓇ which is
formed by turning down the metal which is struck out from between the
projections WW. A further modification is shown in Figures 8 and 9 where
the shuttle is made a flat plate and is operated by the lever arms L², L³ which

and to actuate the shuttle finger S².
O' and P, are the two feed rolls which hold the paper to be printed upon; L, is
the impression hammer which is actuated through a spring mechanism operated by
the key levers. The method of operating this hammer I do not claim to be new,
and it may be any of the already existing devices for that purpose.
The drawings do not show the entire mechanism of a type-writer, but only so
And none of the
much as is necessary for the full understanding of my invention.
mechanism used in well known machines is claimed in this application.
The operation of my invention is simple. The depression of a given key lever
causes one of the horizontal driving arms b, b, to be raised and consequently the
vertical driving lever c, is oscillated, rotating the shuttle arm g, and carrying the
type shuttle to the right or left of its normal point. The characters upon
the shuttle are arranged in such order that when the letter indicated by the key-
lever operated upon is opposite the impression hammer L, the stop arm 21 comes
in contact with the stop pin which has been raised by the same lever. The
hammer actuating mechanism simultaneously causes the hammer to strike and
the contact is made between the character and the paper. As soon as the
pressure is removed from the key lever, the spring 25, draws down the horizontal
driving arms to their normal position, thereby restoring the shuttle arm to its
centre point.
The elevation of the anvil, carrying with it the type shuttle, is accomplished by
the positive action of the levers 13 and 14 which, act upon the shaft E, the return
is caused by gravity assisted by the spring U. It will be noticed that when the
shaft and anvil are elevated the shuttle arm remains in the same position the
screw acting upon the flange t, to retain it. But the length of the finger S, is
sufficient to permit it to act upon the shuttle even when raised to its highest point.
It is obvious that the number of rows of characters upon the type shuttle is
variable at pleasure. If there be only one, the levers 13 and 14 may be dispensed
with, and if there be more than three, there must be a corresponding increase in
the number of elevating levers. The type shuttle shown in Figures 10 to 15 may
be easily removed by turning it around to the side of the anvil and slipping it out
from under the finger S, and that shown in Figures 16-18 by turning the upper
half to one side. Any other shuttle bearing other characters may be then
substituted.
