COMPLETE SPECIFICATION.
Improvements in India-rubber Stamp Mounts.
1, ALEXANDER CRAIGHEAD THOMSON of 113 Union Street, Glasgow, Lanark-
shire, Stationer, 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 has for its object to so make rubber-stamps that a number of
mounts can be fitted interchangably into a single handle.
To effect this object the handle is made with a mount or piece having one or
more dovetail or other grooves or equivalent therein into which groove or grooves
or equivalent mounts, having bevelled edges corresponding to the groove or grooves
or equivalent or having a raised piece or part with suitable edges, can be inter-.
changably fitted.
The groove or grooves or equivalent is or are preferably slightly tapered so as to
securely hold the mounts in place.
And in order that my said invention may be properly understood, I have hereunto.
appended an explanatory sheet of drawings, whereon
Fig. 1 is an end view of a handle.
Fig. 2 is a side view of the handle.
Fig. 3 is a side view of the handle as fitted to the mount.
Fig. 4 is an end view of the mount.
Fig. 5 is a side view of the mount.
Referring to the drawings:
-
The wooden handle a is fitted with a brass collar b.
Fitted to the handle, by.
means of the spike c, shown dotted, is a, preferably, oblong metal plate d having
bevelled edges as shown in side view at Fig. 1. The plate d may be tapered
slightly to one end.
The mount e has on its back a inetal plate which has its sides turned up as.
shown at Fig. 4. The plate f is also, preferably, tapered to one end.
The handle can be fitted to the mount at any time by sliding the plate d of the
handle into the groove g formed by the turned up ends of the plate of the mount.

AI

page_text: tight joint is made.
It will be evident that any number of different. mounts having plates on their
backs can be used with the single handle a.
Under a modification the grooved plate ƒ can be fitted to the handle and the
dovetailed plate d to the mount.
The plate can be of cast metal if so desired.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that. what I
-claim is :-
The improved stamp mount.and handle; substantially as herein before. described
with reference to the drawings annexed, or any, mere modification tliereof."
