Improvements in Pocket Knives.
I WILLIAM BREDE (Engineer) of Paauhau Sugar Mill, Hamakua, Hawaii, Hawaiian
Islands 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 :-
The object of my invention is to combine a whetstone with a pocket knife in such a
way that the stone may be readily removed from the knife and placed in the position
for use.
My invention consists of a knife having at one side of the handle lining a chamber
for receiving a whetstone, the whetstone being attached to the inner surface of one of
the halves of the handle. It also further consists in the combination with the handle
of slides provided with slot bolt holes adapted to engage studs projecting from the
body of the knife.
Reference is to be had to the accompanying drawings, forming a part of this
specification wherein figure 1 is a perspective view of my improved pocket knife
showing one side of the handle removed; figure 2 is a side elevation of the same,
showing one of the slides withdrawn from the end of the handle; figure 3 is an end
elevation of the knife with one half of the handle removed; and figuro 4 is a per-
spective view of one of the slides. Like letters indicate like parts in all the
views.
The handle A is provided with the usual lining a a' and with one fixed cheek
piece b. In place of the opposite check piece of the handle a chambered plate c
of metal or other suitable material is placed against the lining a¹. The rivets at
the ends of the handle are prolonged beyond the chambered plate c having studs d d'
which are provided in opposite sides with rectangular notches e for receiving the
fastening slide.
C
The opposite cheek pieco 6' is provided with a lining a² to which is attached a
whetstone B. The ends of the cheek piece are projected to receive the studs d d'
and they are also mortised to receive slides f¹, said slides being provided
The ends of the
with slots g which are adapted to receive the necks of the studs.
slides project beyond the bolsters and are each provided with a neck i to facilitate
the withdrawal of the slide by the finger nail.
When the check piece is in place on the knife handle, the whetstone B is
contained by the chamber of the plate c, and the slides ff are pushed into the
ends of the cheek piece so as to engage the studs & d' said slides being received in
the notches e of the studs.
When it is desired to remove the whetstone B for use, the slides ff are drawn
out beyond the studs d d¹ as shown in figure 2, when the cheek piece b¹ together
with the whetstone B may be removed and the latter may be used in the ordinary
way.
The withdrawal of the slides f¹ from the handle is prevented by lugs j
projecting from opposite sides thereof, said lugs boing engaged by shoulders in
the bolsters h.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. In a pocket knife, the combination, with the cheek piece b, linings a a¹, the
chambered plate c, the cheek piece 6 having the whetstone B attached to its
inner side, and adapted to enter the chamber of the plate c, and means for
connecting said cheek piece and handle, substantially as shown and described.

page_text: 2. A pocket knife provided with a chambered plate c, notched studs d d', the
apertured cheek piece provided with slotted slides ff, adapted to engage the
studs dd, and the whetstone B attached to the cheek piece and adapted to be
received in the chambered plate c, substantially as shown and describen!.
