A handle for turning the key when locking, or unlocking a door is formed by two
arms which are hinged in slots or grooves formed in the handle of the knife, the
said arms when closed lie. flat and almost flush with the body of the knife, and
when open are at right angles to the same, one on each side of the knife, thus forming
a handle by, which greater force can be used when turning the key.

Combination Penknife, Railway Carriage Key, and Ink Eraser.
I JAMES COOK of 50 Market Street Darwen, in the County of Lancaster
Bookseller, and 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 relates to an improved construction of penknife, or a combined
penknife, railway carriage key, and ink eraser, which knife is so made that in addition
to being applicable as an ordinary penknife it can be used as a railway carriage key;
and its other, and opposite end is made similar to a file, and can be used as an ink,
or pencil eraser.
According to this my invention one end of the haft, or handle of the knife is
enlongated, and being made of metal, and formed in a similar manner to a railway
carriage key, is applicable for locking, or unlocking the doors of railway carriages,
and other similar locks. The opposite end of the haft, or handle is also of metal, and
is serrated, and indented crosswise so as to form a small fine file for use as an ink, or
pencil eraser.
A handle for turning the key when locking, or unlocking is formed by two arms
which are hinged in slots, or grooves formed in the handle of the knife, said arms
when closed lying flush with the body of the knife, and when opened are at right
angles to the same, one on each side of the knife, thus forming convenient, and
powerful handles.
Such being the nature, and object of my said invention the following is a complete
description of same, reference being made to the accompanying drawing forming a.
part of this specification in which :-
Fig. 1. is a side elevation of my improved combined penknife, ink eraser, and key
with the handles for turning the latter closed.

page_text: Fig. 2. is a plan view of Fig. 1, but shewing the handles, for turning the
key, open.
According to this my invention one end of the haft, or handle 1, of the penknife is
enlongated as at 2, and being made of metal, and formed after the manner of a
railway carriage key, is applicable for locking, and unlocking the doors of railway
carriages, and others with similar locks. The opposite end 3 of the haft, or handle 1
is also of metal, and is serrated, and indented, or cut crosswise so as to form a sinall
fine file for use as an ink, or pencil eraser, and other analogous purposes.
A handle for turning the key 2 when locking, or unlocking a door, is formed by
two arms 4. 4 which are hinged at 5. 5. in slots, or grooves 6. 6. formed in the
handle 1 of the knife; the said arms 4. 4 when closed (see Fig. 1.) lie parallel, and
flush, or nearly so with the body 1 of the knife, and when open (see Fig. 2.) are at
right angles to the same, one arm 4 on each side of the knife, thus forming a handle
by means of which greater force can be used when locking, or unlocking.
One or both of the arms 4 form suitable name, or address plates for the owner
of the knife, the handle, or body 1 of which may be of metal, or metal covered with
bone, or horn as ordinary, the blades 7. 7. and other parts of the knife being made
in the usual manner.
A blade spring may be inserted in the slots 6. 6. behind the arms 4. 4. in order
to maintain the latter in the open, or closed position.
Having now particularly described, and ascertained the nature, and object of my
said invention, and in what manner the same is to be employed I declare that what I
claim is :-
A pen, or pocket knife having folding arms such as 4. 4. a railway carriage, and
other key 2 and ink, or pencil eraser such as 3, all in combination as, and for the
purpose herein described, and substantially as illustrated by the accompanying
drawings.
