Improvements in Type Writers.
A communication from abroad by Messrs. WYCKOFF, SEAMANS, & BENEDICT, a
corporation organised under the laws of the State of New York, having their
place of business at 327, Broadway, New York City, New York, in the
United States of America.
I, JOHN CORRY FELL, of the Firm of Fell & Wilding, of 1 Queen Victoria
Street, in the City of London, 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 :-
This invention relates more particularly to carriage raising and releasing means
and to that class of devices for performing column or tabulated work made part of
the subject of Letters Patent of Great Britain, No. 156, of 1892, and consists in the
various features of construction and combinations of devices hereinafter more fully
described and particularly pointed out in the appended claims.
In the accompanying drawings,
Figure 1 is a plan view of the paper-carriage of a Remington type writing
machine, (stripped of its platen, platen-carrier, paper-feeding mechanism, etc.), the
guide and hinge rail, and the usual shift-rail for the platen frame or carrier, and
showing also the present improvements.
Figure 2 is an elevation of the same taken at the left hand end of the machine
with the top-plate added.
Figure 3 is a front elevation of the same.
Figure 4 is a vertical cross-section taken at the line x, x of Figure 1.
Figure 5 is a rear, detail elevation, or a view looking in the direction of the
arrow at Figure 4; and
Figure 6 is a rear elevation, showing a pivoted dog.
In the several views the same parts will be found designated by the same numerals
of reference.
1 designates the posts or pillars, and 2 the top-plate of a Remington machine.
3 is the main carriage hinged by eyes 4 upon the guide-rail 5, and provided with
grooved wheels 6, which run upon said rail. A frame 7 is also hinged to swing
about said rail, and is provided with a feed-rack 8, which co-operates as usual with
the letter-spacing dog 9.
Attached to said hinged frame 7 is an arm 10, which is bent to pass over the
rail 5 and extended forward to terminate contiguous to the rear end of the left hand
side bar of the carriage.
In bearings 11 on the outer side of said side bar is mounted a rock-shaft 12,
which at its rear end is bent inwardly under the said side bar, and rests at its free
end upon the forwardly extending arm 10.
At the free end of the rock-shaft is secured a finger-piece or key 13, which
projects upwardly and inwardly over the said side bar of the carriage.
On the front bar of the carriage at the left hand side is fastened, by screws 14,
a bracket 15, which at each end is provided with a forwardly extending eye or
bearing 16. The bracket between said eyes or bearings is cut-away or open and
between the ends of said bracket immediately over the front rail a space or
opening 17 is left for the passage of the rear arm 18 of a lever 19, a portion of the
front arm 20 of said lever fitting in the space formed between the eyes or bearings 16,
the remainder of the forward arm of said lever 19 being formed or provided with a
handle 21. The said lever 19 is attached, by a screw 22, to a bar 23, which is

page_text: seated or fulcrumed in the eyes or bearings 16 at one end, (thus forming a pivot
for the lever), and which at its opposite end is bent at right angles and rearwardly
to extend over and lie adjacent to the finger-key 13.
Attached to or formed integral with the arm 18 is a depending lug or stop 24,
and attached to the bracket 15, by one of the screws 14, is a spring 25, which is
bent to bear upon the top of the arm 18 and hold the lever 19 down against the
upper side of the front bar of the carriage, as shown clearly at Figure 4.
Mounted upon the top-plate 2, or some other stationary part of the machine, and
preferably by detachable brackets 26, is a rod 27, arranged parallel with the pivot
of the lever 19, and having a series of perforations 28 into which may be fitted one
or more stops or pins 29.
The perforations or holes 28 are arranged apart or graduated to correspond with
the divisions of the machine scale 30. Preferably, however, there is only one hole
in every five figures of the scale, as this arrangement has been found in practice
to be ample. The holes are preferably numbered as shown to aid in facilitating the
work.
At Figure 3 of the drawings, two pins or stops 29 are shown, one at the hole "20,"
and the other at the hole "40" of the said rod 27.
The lower end of the projection, lug, or dog 24, stands in a plane in front of the
line of holes or pins in the normal position of the arm or lever 19, so that in doing
ordinary work the dog 24 may pass freely by the said stops or pins.
By depressing the said arm or lever 19 at its handle end 21 the dog may,
however, engage with said pins upon arriving thereat, and by such engagement or
contact arrest the carriage.
The pointer 31 attached at the axis of the front supporting roller 32 of the carriage
shows at Figure 3 that the carriage has arrived at "30" ou the machine scale.
If it be desired now to have the carriage moved quickly to the point "40"
on the scale (so that a column of figures may be commenced, for example) the
dog 24 is swung rearwardly by bearing down upon the handle portion of the
lever 19.
By this movement the bar 23 is rocked in its bearings, and its rearwardly pro-
jecting portion is caused to rise and bear upon or against the finger-piece of the
rock-shaft and operate to turn said rock-shaft and cause its inner portion to
depress the arm 10 of the hinged frame, and lift the rack-bar 8 from engagement
with the spacing dog.
As soon as this is accomplished, & spring drum or power 33 (which may be of any
known or suitable construction) acts to propel or pull the carriage rapidly towards
the left until the dog 24 strikes or abuts against the stop or pin 29 at the hole "40."
The pressure upon the handle 21 may be then released and the lever contrivance 19
will be returned to its normal position by the spring 25. After the carriage has
been arrested, and the dog permitted to return to its normal position, the writing may
be proceeded with to the full limit of travel of the carriage, as in the arrangement
exhibited there is no pin or stop in place beyond that at the hole numbered "40."
When the lever is released the rack and the rock-shaft are restored to their
normal positions by reason of the superior weight of the hinged frame, which is
sufficient through the rock-shaft, to return the lever 19 to its first position without
the aid of the spring 25, which is employed principally to keep the dog 24 out of
the plane of the pins when the rock-shaft alone is actuated in ordinary work.
The rock shaft or lever is usually designated a "release-key," and this release-
key may be operated independently of the key or lever 19, for releasing the carriage
in ordinary work, and when so operated the key or lever 19 remains in its normal
position, shown in full lines at Figure 4. As the release key may be operated
independently of the lever or column stop key the pins or stops 29 need not be.
removed from their holes in the bar or support when the operator is engaged in
doing ordinary work. While we have shown only two pins or stops, there may be
used as many as the work may demand.
It will be observed that the lever or column stop key is connected to the carriage,

page_text: and that when actuated to move the dog 24 to working position, serves to operate
the carriage releasing devices. It will be further observed that when the dog 24 is
vibrated and the carriage is released the hand is upon the column stop key (or
the carriage), and hence the movement of the carriage towards the left under the
force of its driving spring, may be so regulated or controlled as that the carriage may
be stopped easily, without shock, when the dog comes into contact with the pin.
This invention is of course also adapted to that class of machines wherein a
spring-drum or driving power is dispensed with, and the carriage moved step-by-
step by positive means actuated through the movement of the key-levers.
While we prefer to combine the release key with the column stop key, so far
as some of the features of these improvements are concerned the release key may
be omitted.
Referring to the construction shown at Figure 6, the vertical portion of the
arm 18 of the lever is prolonged and the dog 24 pivoted thereto at 34, for a purpose
which will presently appear. With the construction shown at Figure 4, it will be
seen that if, while the handle is depressed and the dog is swung rearwardly to the
dotted line position shown, it be attempted to return the carriage to the right for
the beginning of a new line or column, the dog 24 would strike against any pin
arranged on the right hand side thereof and arrest the carriage, which would
necessitate a releasement of the lever 19. The construction shown at Figure 6 is
intended to obviate this releasement, and by the same it will be seen that (in
returning the carriage to the right while the dog is held in the plane of the stops
by the depression of the handle portion 21) when said dog encounters the pin, it
will turn about its pivot 34 and ride over said pin, and after passing the same drop
to substantially a vertical position. In order to prevent such tilting or vibration
of the dog when the carriage is moving to the left a pin 35 is provided on the
arm 18.
One of the main objects of this invention is to combine in one device a forwardly
projecting handle, by which the carriage may be lifted to expose the line of print,
with means for doing column work. Heretofore the Remington machine has been
provided at the left hand side with a fixed handle extending towards the operator
to facilitate the raising of the carriage, which handle is also some times used to
return the carriage towards the right when it may not be desired to use either the
release key or the line spacing lever.
In the Patent No. 156 of 1892, above referred to, is shown a key or lever, which
performs only the function of a column stop key or lever, and which is neither
intended nor well adapted to be used as a lifting means for the carriage. It being
desirable to reduce the number of parts in the machine as much as possible, we
have, therefore, so constructed and arranged the column stop key as that it may be
readily employed as a carriage lifter. When used as a carriage lifter, the handle 21
is of course caught underneath, and the dog-bearing arm 18 abutting against the
upper surface of the front bar of the carriage prevents any independent vibration
of the said lever during the turning up of the carriage about the hinge-rod 5 as a
center of motion. If in turning down the carriage said lever should be vibrated it
is immaterial, since upon releasing the same the spring 25 will restore the dog to its
normal position out of the plane of the pins or stops.
Another main object of this invention is to combine a carriage lifter with a
carriage releasing means, so that either the lifting or the releasing of the carriage
may be effected by the operation of a single device. When the handle 21 is raised
the carriage is lifted and when said haudle is depressed the carriage is released.
Thus the combined lifting and releasing means is a most desirable construction
independently of the column-stop devices, which, therefore, may be dispensed with,
as may also the finger-piece of the release key so far as this part of the invention
is concerned.
Another main object of this invention is to so combine the combined lifter and
column stop key with the release key as that the release-key may be operated
independently of the combined lifter and column-stop-key when the pins or column

page_text: stops are in place, so that the carriage may be released and moved towards the left
to the desired point without interruption by the column-stops.
We do not wish to limit ourselves to the employment of pins and holes, as any
known or suitable form of column stops may be employed in lieu thereof, and
without departing from this invention any known or suitable form of release-key
and carriage feeding mechanism may be used in place of the special constructions
which we have elected to show.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
