JESSE W. PIERCE, OF BELTON, TEXAS.
TYPE-WRITING MACHINE.
SPECIFICATION forming part of Letters Patent No. 419,217, dated January 14, 1890.
Application filed July 6, 1888, Serial No, 279,165i (No model,)To call whom it nay conzcermne:
Be it known that I, JESSE W. PIERCE, a
citizen of the United States, residing at Bel-
ton, in the county of Bell and State of Texas,
5 have invented new and useful Improvements
in Type-Writing Machines, of which the fol-
lowing is a specification.
The invention relates to improvements in
type-writers; and it consists in a certain novel
ro construction and combination of devices, fully
set forth hereinafter in connection with the
drawings, and specifically pointed out in the
appended claims.
An object of the invention is to provide
15 means whereby a number of sheets of paper
may be inserted at one time and removed
successively after each page is written, there-
by obviating the necessity of removing the
completed sheet and replacing it by a new
20 one at the end of each page.
A further object of the invention is to pro-
vide improved means for feeding the paper,
whereby the latter is kept flat, so that the
type strikes on a flat surface.
25 A further object of the invention is to pro-
vide improved means for automatically oper-
ating the carriage as the keys are depressed,
whereby more perfect spacing is attained.
A further object of the invention is to pro-
30 vide improved means for operating the type-
bars, whereby the necessary motion thereof
is accomplished by a very slight depression
of the keys, and also by a slight pressure
thereon.
35 A further object is to provide means where-
by the jar and sound caused by the operation
of the type-bars are deadened to render the
machine comparatively noiseless.
These objects are attained in the machine
.o illustrated in the accompanying drawings,
wherein-
Figure 1 is a top plan view. Fig. 2 is a
longitudinal central sectional view, line 1 1,
Fig. 1. Fig. 3 is a side view. Fig. 4 is a front
45 view. Fig. 5 is a transverse section on the
line x x of Fig. 1. Fig. 6 is a detail perspec-
tive view of the spacing-lever. Fig. 7 is a
similar view of the supporting-cylinder for
the operating means for the type-bars. Fig.
50 8 is a transverse sectional view on the line y
y of Fig. 3 to show the spacing mechanism.Fig. 9 is a detail sectional view on the line z
z of Fig. 1 to show the operating mechanism
for the type-bars. Fig. 10 is a detail sec-
tional view to show the adjusting means for 55
the type-bar hangers. Fig. 11 is a detail sec-
tional view of the spacing-pawl. Fig. 12 is a
detail view of one of the type-bars to illus-
trate the manner of arranging the filling.
Fig. 13 is a detail perspective view of one of 60
the detents for the ink-ribbon spools, and
Fig. 14 is a detail perspective of one of the
type-bar hangers.
Referring by letter to the drawings, A des-
ignates the main supporting-frame of the ma- 65
chine, which consists of the base-plate a and
the hollow supporting-arm a', having the an-
nular key-plate a2 and the annular support-
ing-plate a3 arranged on its front end. The
base-plate is provided on its under side with 70
depending standards or pins a', which are
stepped at their lower ends in rubber-lined
sockets b b in the base-board B, whereby the
jar or resonance which is caused in the sup-
porting-flame by the operation thereof is pre- 75
vented from being communicated to the base-
board, and thence to the table or stand on
which the type-writer rests.
C designates the carriage, which is motun ted
in guides or ways c c, arranged above the base- So
plate on suitable supports, whereby the car-
riage is capable of a lateral sliding movement,
and in guides or ways d don the said carriage
is mounted the feed-plate D, having its upper
and lower sides covered with the rubber sheets 85
d'. This feed-plate is capable of a longitudi-
nal sliding movement independent of the
movement of the carriage, and it is controlled
by the feed-roll D', which is mounted trans-
versely under the plate in vertical slots d1 d2 90
in opposite sides of the carriage. The ex-
tremities of the roll beyond the sides of the
carriage are provided with the knobs or han-
dles D2 D2, whereby it may be turned by hand,
and within the carriage the said roll is pro- 95
vided with the spur-wheels D' D', which are
engaged, respectively, by projections d4 d' on
the leaf-springs D' D'. These springs press
upward and normally hold the roller in con-
tact with the under side of the feed-plate, and roo
also hold the roller from rotary movement,
and when one of'the knobs or handles D2 is
