COMPLETE SPECIFICATION.
Improvements in and connected with Dials for Watches and other
Instruments.
I, MARRION ELBERT SHUTTERLY, of Mount Pleasant, in the County of West-
moreland and State of Pennsylvania, United States of America, Gentleman, 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 to dials for watches & other instruments of that class
having adjustable fastenings, whereby a single dial is adapted to be connected
to the frames of different watch movements.
The object of the invention is to provide the fastenings with a detachable
connection with the dial, so that the fastenings may be replaced when broken or
worn, and fastenings of different sizes substituted when desired.
To this end the present invention consists in the combination and arrangement
of parts, as will be hereinafter more fully described, shown in the accompanying
drawing, and particularly pointed out in the appended claims.
In the drawing—
Figure 1 is a plan view of the reverse side of watch dial constructed in
accordance with the present invention.
Figure 2 is a longitudinal sectional view thereof.
Corresponding parts are designated by like reference characters in each figure
of the drawing.
Referring to the accompanying drawing, 1 designates the copper or base of
the dial having three arcuate slots 2 formed through the base. These slots are
widened upon the outer face of the base so as to provide the opposite inwardly
extending flanges 3. The dial face 4 may be formed of enamel, celluloid, or other
preferred material, cemented to the outer face of the base or copper, whereby
the widened portions of the slots 2 are closed at their outer sides, and grooves are
thereby provided between the slots and the face of the dial.
The dial is adapted to be connected to the frame of the movement of the watch
by means of pins 5. Each of these pins is provided with an enlarged head 6,
adapted to be received within the groove or widened part of the respective slots 2,
with the shank of the pin projecting through the open side of the slot. It will
be understood that the pins are capable of a sliding movement longitudinally of
the slots 2, for the purpose of adjusting the position of the pins to accommodate
the same to the frames of various watch movements, and when the pins have been
properly positioned they are connected to the frame of the movement by dial
foot screws in the usual manner.
To render the pins detachable from the dial which is the essential object of
the present invention, the grooves are provided with enlargements 7, adapted
to receive the heads of the pins and permit of the same being removed there-
through. It is preferable to locate the enlargement for each slot at or near one
end and offset to one side thereof, and connected to the slot by means of a trans-
verse slot S forming a communicating passage from the slot to the enlargement.

page_text: The purpose of locating the enlargement to one side of the slot is to prevent the
heads of the pins from becoming detached from the dial by reason of the latter
being accidentally turned and the enlargements alined with the heads of the pins,
as will be understood. To detach the pins from the dial, it is necessary to
entirely remove the latter from the frame of the movement of the watch, when
the pins may be removed to the respective ends of the slots and removed therefrom
through the offset enlargements.
Changes in the form, proportion, size, and the minor details of construction,
within the scope of the appended claims, may be resorted to without departing from
the spirit, or sacrificing any of the advantages of this invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. A dial provided with grooves or slots having enlargements, and headed
fastening pins having their heads slidably received within the grooves or slots
and adapted to be positioned and removed through the enlargements thereof,
substantially as and for the purpose set forth.
2. A dial having grooves or slots formed therein, each slot or groove being pro-
vided with a transverse branch or passage communicating with an enlargement
of the slot or groove, and headed fastening pins having their heads slidably
received within the slots or grooves and adapted to be positioned and removed
through the enlargements, substantially as shown, and described.
3. A dial having arcuate slots or grooves formed therein, each slot having at
one end an inwardly extending transverse extension or branch forming a passage
communicating with an offset enlargement of the slot or groove, and headed
fastening pins slidably received within the arcuate slots or grooves and adapted
to be positioned and removed through the offset enlargements thereof, substantially
as shown and described.
Dated this 9th day of May 1899.
