Improvements in the Construction of Forge and Tilt Hammer
Helves.
I, DANIEL SMITH, Junior, of Raglan Street, Wolverhampton in the County of
Stafford, Mechanical Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in the helves of forge and tilt hammers and
consists in methods of making them considerably stronger, and imparting a greater
degree of elasticity thereby making them more durable.
According to this invention in the case of helves made of wood 1 divide the helve
vertically down its centre into two parts in the direction of its length, and between
these parts I secure a corrugated plate of iron or steel the full length and depth of
the helve. The plate corrugated transversely to its length and the corrugations
extend the whole length of the plate; or such plate may be left plain in those parts
embraced by the hammer head, hurst and tail collar. I have described one plate only
as being used, but two or more may be used if desired.
If desired I may make a helve by 3 or more plates corrugated as described and
distanced apart by wood or other blocking so as to fill up the head, hurst and tail-
collar and enable them to be secured on to such parts.
I am aware that strengthening helves by means of a plate or plates inserted in the
wood is now new but the novelty in this invention consists in corrugating the plate or
plates used so that the helves may be more elastic and stronger and more durable than
in the case where plain wood or wood and iron or steel plates are used.
According to another method of carrying out this invention I make the helve in the
form of a tube the corrugations being formed transversely or thereabouts to its
'length.

COMPLETE SPECIFICATION.
Improvements in the Construction of Forge and Tilt Hammer
Helves.
I, DANIEL SMITH junior of Raglan Street Wolverhampton in the county of Stafford
Mechanical Engineer do hereby declare the nature of this Invention and in what
manner the same is to be performed particularly described and ascertained' in
and by the following statement, reference being had to the accompanying drawings
and the letters of reference marked thereon (that is to say):
:-
This Invention relates to improvements in the helves of Forge and Tilt Hammers
and consists in methods of making them considerably stronger, and imparting a
greater degree of elasticity, thereby making them more durable.
The invention will be readily understood on reference to the Drawings herewith.
Figures 1 to 5 inclusive shew one modification of carrying out this invention and
the remaining methods will be described hereafter.
Figure 1 is a side view of a helve constructed according to one method of this
invention.
Fig. 2 is a sectional plan taken on line xx of fig. 1. The remaining figures will
be described later on.
According to this invention I divide the helve vertically down its centre into two
parts A and B in the direction of its length. Between these parts I place a

page_text: corrugated plate C of iron or steel the full length and depth of the helve as shewn.
The plate is corrugated transversely to its length as shewn, and I prefer to shape the
inner faces of the parts A and B to suit the corrugations of the plate in. that part
embraced by the hurst D as shewn, and the part embraced by the hammer-head
and tail collar may be left plain as shewn if desired. a a etc. are straps of wrot iron
that partially embrace the parts A and B, and bb etc. are bolts passing through these
straps and through the parts A and B and through the corrugated plate for the
purpose of keeping such plate in position. Fig. 3. which is a section taken on line y y
of Fig. 2 shews these straps. Fig. 4 shews the part B of the helve in sectional plan as
shewn by fig. 2. Fig. 5 is a section taken on line 2 of fig. 1. ce are flanges on the
top and bottom of the plate C as shewn on that part projecting beyond the hammer
head. These flanges, which are let into the wood prevent the plate C as it springs
from cutting into the wooden key k in the hammer head. I have described one
corrugated plate only as being used but two or more may be used if desired, and
instead of using the straps a a etc. I may if desired use a plate (or plates) of-
corrugated iron or steel to partly embrace the wood.
If desired I may make a helve of three or more plates corrugated as described and
distanced apart by wood or other blocking, so as to fill up the head hurst and tail
collar and enable them to be screwed on to such parts. According to another method
of carrying out this invention I may make the helve in the form of a tube, the
corrugations being formed transversely or thereabouts to its length.
I am aware that strengthening helves by means of a plate or plates inserted in the
wood is not new, but the novelty in this invention consist in corrugating the plate or
plates used so that the plates may be more elastic, making the helve much stronger
and more durable than is the case when plain wood or wood and iron or steel plates
without corrugation are used, as a flat plate used vertically is so intensely rigid as
speedily to become fractured by the working of the hammer.
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
1. The construction of Forge and Tilt Hammer helves as described and shewn by
figs. 1 to 5 inclusive.
2. The use of one or more corrugated Iron or steel plates in combination with
wood blocking as herein described.
3. The use of Corrugated Iron or steel plates for the purpose of stiffening and
strengthening Forge and Tilt Hammer helves.
4. Bending the plate over as shewn at cc in fig. 5 for the purpose of forming a
larger bearing on the upper and lower edges of the corrugated plate, so as to be less
liable to cut into the wood or other blocking and to secure the parts together.
5. The modification herein described using the corrugated iron or steel side plates
partly embracing the wood parts and secured thereto by the bolts b.
6. The modification herein described forming the helve as a corrugated iron or
steel tube.
