improvements in Tape Measures.”
We, PERCY TYZACK and ALFRED HOLMES, both of Standard Works, Cavendish.
Street, in the City of Sheffield, Manufacturers, do hereby declare the nature of
our invention to be as follows:-
:-
Our invention of improvements in what are known as tape measures, or measur-
ing tapes which are coiled up within a case or cover, relates more particularly
to the winding axles of such articles.
It is usual to pass the axle of the barrel upon which the tape is wound nearly
through the case, and to screw into its end which is bored and screwthreaded, a
short screw, the head of which is preferably tapered, and formis the neck or bear-
ing for that end of the axle, revolving in a metal cap or washer affixed to the case.
There is a tendency due to varying causes, in this screw to become loose, for
example friction, wear of the parts, and the like, and to remedy this we use the
following means; upon the outside of the axle we have a key or projection and we
enlarge the centre hole of the metal cap which forms the bearing.
We also pre-
pare a metal bush or sleeve to fit upon the axle having a slot to engage with the
key or projection before mentioned, and its outer end enlarged to fit into the
centre hole of the cap and to receive the head of the screw.
It will therefore be seen that it is the bush or sleeve which revolves in the
cap, and that there is no tendency whatever to loosen the screw when the axle
is revolving.
"
The designation "tape measure is intended to include any kind of measure
which is coiled within a case or cover.

Pape Measures.
We, PERCY TYZACK and ALFRED HOLMES, both of Standard Works, Cavendish
Street, in the City of Sheffield, Manufacturers,, do hereby declare the nature of
this invention and in what manner the same has to be performed, to be particu-
larly described and ascertained in and by the following statement:-

Our invention of improvements in what are known as tape measures," or

page_text: measuring tapes which are coiled up within a case or cover, relates more
particularly to the axles upon which the tape is wound.
It is usual in such articles of the ordinary make to pass the barrel or axle
upon which the tape is wound, nearly through the case, and to screw into its
end which is bored and screwthreaded for the purpose, a short screw, the head of
which is preferably tapered to form the bearing neck for that end of the said
axle, and which revolves with the axle in the centre opening of a metal washer
affixed to the case.
There is a tendency (due to various causes such as friction, wear of the parts
and such like) in this screw to become loose, and our invention is chiefly to avoid
this defect with its annoyance.
Our invention is illustrated in the annexed sheet of drawings, like figures of
reference, refer to like parts in all the figures.
Fig. 1, is a plan of a tape measure, with the central screw removed.
Fig. 2, elevation and section of our sleeve.
Fig. 3, section of central part of case, showing the axle and sleeve in section
with the screw in position.
The case is marked 1, the central washer or cap which forms the bearing for
the axle is marked 2, the axle 3, its key 4, and screw hole 5.
Upon the axle 3, where it is reduced in diameter, we form a key or projection 4,
and we enlarge the centre hole of the washer 2, to receive a sleeve or short tube 6,
shown in Fig. 2, and prepared with a slot 7 to pass over and engage with the
key 4, upon the axle 3, so that it will be carried round by the axle.
This sleeve is expanded at its outside end and prepared to receive the coned
head of the screw 8, which can be screwed into the screwthreaded end of the axle
as shown in Fig. 3.
The expanded end of the sleeve fits into the correspondingly shaped centre
opening of the washer 2, which forms the bearing for it.
It will therefore be understood that instead of the screw revolving in a fixed
bearing as before, it is the sleeve 6, which revolves in the washer, and conse-
quently there is no action upon the screw which tends to unscrew or otherwise
loosen it. The usual folded winding up handle is marked 9.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
The improvements in tape measures consisting of a sleeve 6, provided with a
slot or keyway 7, to engage with a key or projection 4, upon the winding axle 3,
and to receive and protect the screw S, substantially as hereinbefore described,
with reference to the drawings.
