No. 23377.—28th August, 1907.—NATIONAL CASH REGISTER COMPANY, a corporation organized and existing under
and by virtue of the laws of the State of New Jersey, United
States of America, with factories and general offices at Dayton,
Montgomery, Ohio, United States of America (assignees of
William F. Bockhoff, of Cleveland, Ohio aforesaid). Improvements in manifolding automatic sales-books.

Extract from Specification.—This invention relates to mani-folding automatic sales-books, and has for its main object
to provide an improved construction of duplicating or tripli-cating book in which the original sheet as well as the one or
more copies are adapted to be removed from the book and
folded as desired. Another object is to provide an improved
book of the class described, in which the carbon transferring
material is applied to the sheet so that no separate carbon
sheet is necessary. A further object is to provide a book
in which the separate sheets are fastened to the cover by a
loose stapling, whereby the sheets may be easily detached
from the cover without leaving any stub.

[NOTE.—The above extract from the specification is inserted in place
of the claims.]

No. 23378.—1st November, 1906.—EDWIN GEORGE HARROP,
of 1 Amwell Street, Clerkenwell, London, England, Manufacturing Jeweller. An expanding flexible bracelet.

[NOTE.—This is an application under section 106 of the Act, the date
given being the official date of the application in Great Britain.]

Claim.—An expanding flexible and foldable bracelet,
composed of hollow links of uniform size disposed alternately as middle links with longitudinal slots and as outer
links with cross-pins engaged in said slots, the said links
being normally held in the contracted position by helical
springs of nearly the same diameter as the interior of
the links inserted in the ends of the middle links, these
springs being inserted after the whole bracelet is hard-soldered together by winding spirally through the longitudinal
slot, thus requiring no other opening for their insertion,
substantially as described with reference to the drawings.

No. 23381.—28th August, 1907.—JOSEPH GEORGE COOMBS,
of 99 York Street, Sydney, New South Wales, Australia,
Smith. Improvements in diaphragms or tympan for phonographic and telephonic apparatus.

Claims.—(1.) A diaphragm for phonographic and telephonic
apparatus, consisting of a flat vibratable ring and a domed
rigid central part of extreme thinness. (2.) A diaphragm
for telephonic receivers, consisting of a domed central part
and a vibratable ring surrounding the same slightly dished
to oppose the drag of the magnet. (3.) A diaphragm for
phonographic apparatus, consisting of a vibratable ring and
a central domed portion, both of extreme thinness, and having
an apex on the dome adapted to facilitate attachment of the
stylus and reproducing button. (4.) A diaphragm for phonographic and telephonic apparatus, in which the vibrations are
applied around the inner edge of a vibratable ring which carries
a domed central part of extreme lightness vibrating with said
ring, but in itself incapable of vibration relatively thereto.

No. 23382.—28th August, 1907.—CHARLES WILLIAM SPONSEL, of 36 Pearl Street, Hartford, Connecticut, United
States of America, Engineer. Improvements in typewriters.

Extract from Specification.—In machines of this type, particularly those wherein the printing is done by pressure and
not by impact, it is necessary to adjust the type-carrying
mechanism to and from the platen of the machine in order
that the type may be brought to a uniform printing position,
and it is also necessary that the parts be so constructed as
to be capable of being held rigidly after adjustment. The
different mechanisms employed to operate the printing devices being in almost constant use considerable friction
necessarily takes place, and it is therefore desirable to construct the bearings of the moving parts in such a manner
that as little wear as possible may result. It is also desirable to provide means for connecting the type-actuating
mechanism with the impression levers, whereby easy detachment may be made to allow adjustment. It has also been
found desirable to arrange stops for the impression-levers
or other movable mechanism whereby motion may be arrested
without impact or concussion, thus eliminating the disagreeable element of noise prevalent in machines of other types.

of the claims.]

No. 23383.—28th August, 1907.—WELLINGTON PARKER KIDDER, of 18 Robeson Street, Jamaica Plain, Boston,
Suffolk, Massachusetts, United States of America, Engineer.
Improvements in typewriting machines.

Extract from Specification.—One of the chief obstacles in
the way of complete visibility of the writing in machines of
the front or top-strike type as hitherto constructed resides in
the difficulty of carrying the ribbon clear of the platen to uncover the writing when the same has been pressed thereagainst
by the types. It is the aim of this invention, which will presently be explained in detail, to eliminate the above difficulty and attain other desirable ends by providing a construction wherein the ribbon is normally held away from the printing-point in a relatively taut condition, but that portion thereof adjacent the printing-point is automatically slackened
when the type-bars are progressing towards the platen so as
not to impede their movements, such slack being taken up
and the ribbon carried from the platen during the returning
of the type-bars to their normal positions.

of the claims.]

No. 23384.—28th August, 1907.—WELLINGTON PARKER KIDDER, of 18 Robeson Street, Jamaica Plain, Boston,
Suffolk, Massachusetts, United States of America, Engineer,
and CHARLES WILLIAM SPONSEL, of 36 Pearl Street, Hartford, Connecticut, United States of America, Engineer. Improvements in typewriting machines.

Extract from Specification.—The writing machine to which
the invention is especially adapted comprises a type known
as “Silent Typewriters,” wherein the printing characters
press against the impression surface in contradistinction to
the usual types which effect printing by impact or concussion
of the printing characters. It is essential in this type of
machine that an absolutely rigid impression surface be provided, as any movement of the platen under pressure of the
printing device seriously affects the quality of the work,
and especially is this true where considerable pressure is exerted to produce a large number of copies, as in manifolding.
It is, moreover, desirable that the platen be capable of adjustment toward or from the normal printing plane, which is the
common plane occupied by the front faces of the printing
characters in their extreme projected position. By this invention, which will presently be described, the above, among
other ends, is attained by anchoring a tie-rod in the front
rigid frame-work of the machine, and extending the same
transversely thereof to the rear of the platen behind the
printing-point thereof to provide a rigid abutment therefor,
leaving the rear portion of the machine substantially free
from supporting frame-work. Means operatable from a convenient location are also provided for shortening or lengthening the effective length of this tie-rod, enabling the operator
at will to cause the platen to advance or recede from the
normal printing plane, the amount of movement thereof in
either direction being indicated by a suitable device visible
at all times to the operator.
