WILLIAM TIMMS 42 Hume Torrace Yarm Road Darlington Commercial Traveller
do hereby declare the nature of this invention to be as follows:―
This invention relates to an improved Pocket Knife Sharpener and Glass Cutter
Combined. In carrying out the object of this invention I take a strip of any sheet
metal but preferably Steel of convenient width and thickness. I then perforate,
corrugate or serrate this said strip of metal the necessary part of it I then attach or
consolidate by means of a suitable cement to the said strip of metal any abrasive
substance such as Emery, Corrundum, Washita Stone or Arkansas Stone or other sub-
stance used for the purpose of sharpening Knives, the perforated corrugated or
serrated strip of metal forms a core gives great holding power to the cement and
prevents the abrading substance from breaking away when in use and giving great
resisting power. The abrading substance being consolidated on to the strip of metal
or core as herein described and cut or moulded to convenient shape allows of the Knife
being sharpened by rubbing upon it in the ordinary way.
At one end of the said strip or core of metal as herein described I rivet two folding
caps or covers stamped or shaped of sheet metal most suitable these caps or covers
folding inwards or outwards the rivets acting as an hinge when folded inwards they meet
longitudinally at the centre of core or strip of metal with abrading substance attached
thus completely enclosing same and locked or fastened together by means of a suitable
catch prevents any oil or dirt from coming in contact or soiling the clothes when
carried in the pocket and not in use. The said two covers or caps when folded out-
wards form a handle by means of the suitable catch at the ends to lock them in position
and thus holds firm the core or strip of metal with abrading substance attached while
being acted upon when in process of rubbing or sharpening the Knife. I also at the
same end of core or strip of metal to which the folding covers or caps are attached
cut a small slot internally into the metal and insert into this slot a small disc of
hardened Steel with V shaped cutting edge rotating on a pin rivetted into the slot
this disc of Steel when revolved on the surface of glass indents or cuts same thus
combining in the same article a Knife Sharpener and Glass Cutter which can be made
of convenient size to be carried in the waistcoat or other pocket.

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 :-
O
This invention relates to an Improved Pocket Knife Sharpener and Glass Cutter
Combined. In carrying out the objects of this invention I take a strip of any sheet metal a
but preferably steel of convenient width and thickness. I then peforate corrugate or
serrate this said strip of metal the necessary part of it, I then attach or consolidate by
means of a suitable cement to the said strip of metal any abrasive substance such as
Emery, Corundum Washita Stone or Arkansas Stone or other substance used for the
purpose of sharpening Knives the perforated corrugated or serrated strip of metal a
forms a core gives great holding power to the cement and prevents the abrading
substance from breaking away when in use and giving. great resisting power. The

abrading substance being consolidated on to the strip of metal or core as herein
described and cut or moulded to convenient shape allows of the Knife being sharpened
by rubbing on it in the ordinary way. At one end of the strip or core of metal as
herein described. I rivet two folding caps or covers C stamped or shaped of sheet metal
most suitable these caps or covers folding inwards or outwards the rivets acting as a
hinge when folded inwards they meet longitudinally at the centre of the core or strip
of metal with abrading substance attached thus completely enclosing same and locked
together by means of a suitable catch d prevents any oil or dirt from coming in
contact or soiling the clothes when carried in the pocket and not in use.
two covers or caps C when folded outwards form a handle by means of a suitable
catch d at the ends to lock them in position and thus holds firm the core of metal
with abrading substance attached while being acted upon wlien in process of rubbing
or sharpening the Knife. I also at the same end of core or strip of metal to which the
folding covers are attached cut a small slot internally into the metal and insert into
this slot a small disc E of hardened steel with ✓ shaped cutting edge rotating on a
pin rivetted into the slot this disc E of steel when revolved on the surface of glass
indents or cuts same thus combining in the same article a Knife Sharpener and Glass
Cutter made of convenient size to be carried in the waistcoat or other pocket..
.
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 wlíat I claim is
1. A strip of metal a preferably steel of convenient width and thickness this said
strip of inetal being perforated with a series of small holes also serrated or corrugated
this strip of metal forming a core to which any abrading substance such as Emery
Corundum or other abrasive material may be attached and consolidated by means of a
suitable cement on to the said strip of metal the perforations and serration giving
great holding and resisting power to the abrasive material on which the Knife is
rubbed to be sharpened.
2 Inserting at one end of the strip or core of metal a to which the abrasive sub-
substance is attached as described a small disc E of hardened steel with V shaped
cutting edge rotating on a pin rivetted into a slot or insertion at the end which when
revolved, on the surface of glass indents or cuts same thus combining a Glass Cutter
and Knife Sharpener on the same strip or core of metal.
3 Attaching to the strip or core of metal a with abrasive substance consolidated on
same by means of rivets at one end two folding caps or covers c shaped or stamped
of sheet metal and folding inwards and outwards the rivets acting as a pivot or hinge
the said caps or covers when folded inwards completely enclosing the strip or core of
metal with abrasive substance thus preventing oil or other foreign substance from
soiling the pocket when not in use.
When said. covers or caps c are folded outwards they form a handle by means of a
suitable catch d to keep them in position holding or grasping same when in the act of
sharpening Knife.
