Solicitors, at Frankfort-on-the-Main, in the Empire of Germany, for the Inven-
tion of "AN IMPROVED REMONTOIR FOR MANTEL CLOCKS." A communication

of the Commissioners of Patents on the 30th October 1877..
FRANK WIRTH, of the Firm of Wirth and Company, Patent Solicitors, at Frank-
fort-on-the-Main, in the Empire of Germany. "AN IMPROVED REMONTOIR' FOR
MANTEL CLOCKS." [A communication from George Crespel, of Frankfort-on-the-
Main, in the Empire of Germany.]
This Invention relates to a novel winding apparatus or "remontoir" to be applied
to clocks, so as to enable such clocks to be wound up and set from the front or
side independently of keys, and dispensing with unsightly holes in the dial.
In carrying out this Invention the shaft of the striking train, the shaft of the
hands, and the shaft of the running train are provided with smal bevel wheels,
which gear into three other bevel wheels of equal size, mounted on separate axles.
At the other end of these axles are placed three other bevel wheels gearing in their
turn into three bevel wheels mounted on horizontal axles. These latter axles go
right through below the clock to the front, and are each provided with milled
thumb and finger knobs, and by turning these knobs, the striking train, the
running train, or the hands can be respectively wound up or set.
The object of this arrangement is not only to avoid the use of a key, but
principally that the clock can be wound up or set without taking off glass shades
or opening the dial glass. It also dispenses with the necessity of opening the clock
ГР

page_text: to set the hands. The clock is shut up quite dust-tight, thus preventing injurious
matter entering the works.
It must be understood that this Invention is not confined to the use of bevel
wheels as other toothed wheels may be used, or pulleys driven by chains, silk cords,
catgut, or like means.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Frank Wirth in the Great Seal Patent Office on the 29th April

FRANK WIRTH, of the Firm of Wirth and Company, Patent Solicitors, at Frank-
fort-on-the-Main, in the Empire of Germany. "AN IMPROVED REMONTOIR' FOR
MANTEL CLOCKS." A communication from George Crespel, of Frankfort-on-the-
Main, in the Empire of Germany.
This Invention relates to a novel winding apparatus or "remontoir" to be
applied to clocks, so as to enable such clocks to be wound up and set from the
front or side independently of keys, and dispensing with unsightly holes in the
dial.
In carrying out this Invention reference is to be had to the accompanying
Drawings, Figures 1, 2, 3, where it will be seen that is the shaft of the striking
train; c, the shaft of the hands; and b, the shaft of the running train, which are
provided with small bevel wheels d', d², d³, which gear into three other bevel
wheels e', e, es, of equal size mounted on separate axles f¹, f, f³. At the other
end of these axles f,f2, f³, are placed three other bevel wheels k₁, k², k³, gearing in
their turn into three bevel wheels x1, x2, ³, mounted on horizontal axles g¹, g², g³.
These latter axles go right through below the clock to the front, and are each
provided with milled thumb and finger knobs h1, h2, h3, and by turning these knobs
the striking train, the running train, or the hands can be respectively wound up
or set..
The object of this arrangement is not only to avoid the use of a key, but
principally that the clock can be wound up or set without taking off glass shades
or opening the dial glass. It also dispenses with the necessity of opening the clock
to set the hands. The clock is shut up quite dust-tight, thus preventing injurious
matter entering the works.
It must be understood that this Invention is not confined to the use of bevel
wheels, as other toothed wheels may be used, or pulleys driven by chains, silk cord,
catgut, or other like means.
In witness whereof, I, the said Frank Wirth, have hereunto set my hand and
seal, this Twenty-fourth day of April, in the year of our Lord One thousand
eight hundred and seventy-eight.
FRANK WIRTH. (L.S.)
