I, JOHN HATTON, of New Street, Old Swinford, Worcestershire, Spade Maker,
do hereby declare the nature of my invention for "IMPROVEMENTS IN THE
CONSTRUCTION OF TILT-HAMMER HELVES AND HANDLE AND OTHER SHAFTS OR
ARMS AND THE LIKE to be as follows:-
"
My Invention relates to improvements in the construction of tilt-hammer helves
such as are made of wood and it is applicable to other purposes such for instance
as the shafts of picks, hammers, adzes and other hand tools, the shafts of carts and
other vehicles and the handles or sides of barrows, trucks and trollies.
The said parts of such articles being made of wood and subjected to continual
vibration when in use are apt to break. The object of my Invention is to provide
means whereby the said parts of such articles can be very materially strengthened
at a small cost without increase in their bulk and with but little increase in
weight.
In carrying my said Invention into practice I cut a longitudinal slit along the
tilt-hammer helve or other article. The said slit is preferably central and may
extend either from end to end thus dividing the article lengthways into two pieces
or it may extend as far from one end towards the other as may be desired. It is
cut in the direction of the greatest strain to which the article will be subjected.
I insert in the said slit a strip of sheet or plate metal of the same thickness as the
slit and of the same width as the article to which it is applied and I affix the strip
and the article together by means of metal bands or by rivets or bolts. For shafts
of hand tools I prefer to use rivets which are flush so as to offer no obstruction to
the hands. I sometimes find it desirable to use more than one strip of metal as
above described and I then cut two or more slits in the article side by side and use
a corresponding number of strips of metal and affix or bind the whole together as
above described for a single strip.

page_text: Improvements in the Construction of Tilt-hammer Helves, and
Handle and other Shafts, or Arms, and the like.
I, JOHN HATTON, of New Street, Old Swinford, Worcestershire, Spade Maker,
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 reference being had to the accompanying drawing and to the letters and
Figures marked thereon, that is to say :-
My Invention relates to improvements in the construction of tilt-hammer helves
such as are made of wood and it is applicable to other purposes such for instance
as the shafts of picks, hammers, adzes and other hand tools, the shafts of carts and
other vehicles and the handles or sides of barrows, trucks and trollies.
The said parts of such articles being made of wood and subjected to continual
vibration when in use are apt to break. The object of my Invention is to provide
means whereby the said parts of such articles can be very materially strengthened
at a small cost without increase in their bulk and with but little increase in
weight.
In carrying my said Invention into practice I cut a longitudinal slit along the
tilt-hammer belve or other article. The said slit is preferably central and may
extend either from end to end thus dividing the article lengthways into two pieces
or it may extend as far from one end towards the other as may be desired. It is
cut in the direction of the greatest strain to which the article will be subjected.
I insert in the said alit a strip of sheet or plate metal of the same thickness as the
slit and of the same width as the article to which it is applied and I affix the strip
and the article together by means of metal bands or by rivets or bolts. For shafts
of hand tools I prefer to use rivets which are flush so as to offer no obstruction to
the hands. I sometimes find it desirable to use more than one strip of metal as
above described and I then cut two or more slits in the article side by side and use
a corresponding number of strips of metal and affix or bind the whole together as
above described for a single strip.
Fig. 1 of the accompanying drawing represents in side elevation a tilt-hammer
helve constructed according to my Invention; Fig. 2 is an end elevation and Fig. 3
is a plan of the same; Fig. 4 represents an elevation, Fig. 5 a plan and Fig. 6 an
end view of one of the pieces of wood forming a side of the same; Fig. 7 is a plan
and Figs. 8 and 9 are a side and an end elevation respectively of the metal plate
for strengthening the same, and Fig. 9* is a plan of a modified form of the tilt-
hammer helve represented by Figs. 1, 2 and 3.
The same letters of reference indicate the same parts in Figs. 1, 2, 3, 4, 5, 6, 7, 8,
9 and 9*.
A is a tilt-hammer helve constructed according to my Invention, a being the
fulcrum, a¹ the end at which the hammer is fixed, and a the end which is operated
upon by the cam. . I cut a slit b along the tilt-hammer helve preferably central
which may extend either from end to end (see Fig. 3) thus dividing the helve
lengthways into two pieces a³, a or it may extend as far from one end towards the

page_text: other as may be desired. The slit b is cut in the direction of the greatest strain to
which the hammer helve is subjected. I insert in the said slit 6 a strip of sheet or
plate metal B, shewn separately at Figs. 7, 8, and 9, of the same thickness as the
slit and of the same width as the tilt-hammer helve A. I affix the strip B and the
sides a³, a, together by means of metal bands C, C and bolts D, D, passing through
holes d, d and I prefer to add the dowels E to give additional strength. I some-
times find it desirable to use more than one strip of metal B, as above described,
and I then cut for instance two slits b, b¹ side by side, see Fig. 9*, or more than two
slits may be used and I use a corresponding number of strips of metal B, B' and
affix or bind the whole together as above described for a single strip.
Fig. 10 represents a pick shaft having a slit cut therein for the insertion of
a metal plate, according to my Invention; Fig. 11 shews the metal plate separately
for the pick shaft illustrated by Fig. 10; Fig. 12 shews the completed pick shaft
and Fig. 13 shews a modified form of the same.
The same letters of reference indicate the same parts in Figs. 10, 11, 12 and 13.
D is the pick shaft having a slit b extending either from one end for a certain
distance towards the other, as shewn by Figs. 10 and 12, or the slit b may extend
the whole length of the shaft, as shewn in Fig. 13. B is the metal plate shewn
separately at Fig. 11 which is inserted in the slit b. The whole may be affixed
together by rivets E or metal bands or other suitable means may be employed.
I construct shafts or handles for hammers and other similar hand tools similarly
as above described with reference to a pick shaft or handle.
Fig. 14 represents a cart shaft constructed according to my Invention. F is the
cart shaft, fi is the free end and f' is the end which is attached to the cart. I cut
a slit b from the end f' towards the free end f¹ in a vertical direction and I insert
a metal strip or plate B and I affix the whole together by rivets E or by metal
bands or other suitable means. Shafts of carriages and other vehicles can be
constructed similarly as above described with reference to a cart shaft.
Fig. 15 represents three views of a pole for carriage, omnibus, coach or other
similar vehicle constructed according to my Invention. G is the carriage or other
pole, g' is the free end thereof and g is the end which is attached to the carriage
or other vehicle. I cut a slit b from the end g² towards the free end gl in a vertical
direction and I insert a metal strip or plate B and I affix the whole together by
rivets E or by metal bands or other suitable means.
Fig. 16 shews four views of a whippletree constructed according to my Inven-
tion. His the whippletree, h, h¹ being the free ends and h² the intermediate point
at which it is attached to the vehicle. The slit b extends from end to end in
a horizontal direction and is filled by a strip or plate B and the whole is affixed
together by means of the rivets E and straps h¹, h³.
Fig. 17 represents three views of a lever for raising the rails on railways
constructed according to my Invention. I is the railway lever, it is the end thereof
to which a rope is often attached when in use and the other end is protected by the
shoe 22 placed under the rail or other article to be raised. I cut a slit b from the
end almost or quite to the end 2 in the direction of the greatest strain to which
the lever will be subjected when in use and I fill such slit by a plate B and I affix
it to the lever by rivets E or by metal bands or straps or other suitable means.
Levers for other purposes can be constructed similarly as above described with
reference to a railway lever.
Fig. 18 represents two views of a handle or part of side-frame of a wheelbarrow
or other similar vehicle constructed according to my Invention. K is the wheel-
barrow handle or part of side-frame, k¹ being the handle end, ² the end near the
wheel and the mortices in which the tongues on the bottom of the wheelbarrow
fit. The wheelbarrow handle or part of side-frame is divided longitudinally in a
vertical direction by a slit b in which fits the plate B the whole being fixed together
by the rivets E or by other suitable means.
Fig. 19 represents in plan and elevation a handle for a trolley or other similar
vehicle constructed according to my Invention. L is the trolley handle, a being

page_text: the handle proper and 12 that end of the same which is attached to the trolley.
I cut a slit 6 from the end as far as is desirable towards the end ¹ and in
it I insert a metal strip or plate B and affix the whole together by means of the
rivets E or by other suitable means.
I have described the pick shafts and similar shafts or bandles, cart shafts
or similar shafts, carriage poles or similar poles, whippletrees or similar articles,
railway levers or similar levers, handles or parts of side-frames of wheelbarrows or
similar vehicles, handles of trolleys or similar handles as being provided with a
single strip or plate of metal only but two or more such strips or plates may be
used as described with reference to the tilt-hammer helve illustrated by Fig. 9*.
Although I have described the various articles as first formed of a single piece of
wood which is afterwards slit partly or wholly through still I do not limit myself
to this mode of manufacture as I sometimes find it more convenient to make such
articles, particularly when slit all along, of two or more separate pieces of wood
shaped and affixed together as herein before described.
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 what
I claim is
Strengthening tilt-hammer helves, pick shafts or similar shafts or handles, cart
shafts or similar shafts, carriage poles or similar poles, whippletrees or similar
articles, railway levers or similar levers, handles or parts of side-frames of wheel-
barrows or similar vehicles, handles of trollies or similar handles, by means of a
metal strip or plate or by means of two or more metal strips or plates inserted in
and filling up a longitudinal slit or division or two or more longitudinal slits
or divisions in such article or articles, the said strip or plate, or strips or plates,
being situated in a plane or planes parallel to the direction of the greatest strain to
which the article or articles will ordinarily be subjected to as hercinbefore described
and illustrated in the accompanying drawing.
