Improvements in Machinery for Rolling the Backs of Scythes,
Hooks, and the like.
I, WILLIAM HAYDN HAVENHAND of 225 Albert Road Sheffield in the
County of York, Traveller, do hereby declare the nature of my invention to be as
follows:-
This invention has for its object to facilitate the manufacture of the iron or
steel backs, used for strengthening the blades of scythes, reaping hooks and the
like, and it consists briefly in the construction of a machine for rolling the said.
backs to the required taper or bevilled form from the strip of material.
The apparatus or machine consists of a strong frame or bed provided with a
travelling table preferably driven by a rack and pinion connected with driving and
reversing motion similar to that of an ordinary metal planer.
About the centre of the bed I fix a pair of housings or like standards carrying a
pair of adjustable rolls, so arranged that the travelling bed or table passes between
them and takes a bearing upon the lower roll.
The top of the table is provided with screw dogs or equivalent means for holding
and adjusting a rolling bed upon which the strip of metal to be operated upon
is fixed.
This rolling bed is prepared with a longitudinal recess bevilled and tapered to
the required form of the required "back" before it is curved, the width and taper
being regulated by an adjustable strip which forms the back of the recess, and
which fits upon an inclined face, and is secured thereto by screws.
At the largest end of the recess I make a bellmouthed opening for convenience
in placing the strip of metal to be rolled, in position.
The strips are prepared by cutting a bar of iron or steel longitudinally with a
long diagonal cut, producing two tapered strips; these are heated, and are placed
singly in the machine, and subjected to the action of the rolls.
The lower roll supports the table and work exactly under the centre of the upper
roll, which acts upon the strip rolling into the long recess before described and
thereby producing a strip or back of the required form and size.
Deted the 23rd day of August 1890.

COMPLETE SPECIFICATION.
Improvements in Machinery for Rolling the Backs of Scythes,
Hooks, and the like.
I, WILLIAM HAYDN HAVENHAND of 225 Albert Road, Sheffield in the
County of York, Traveller, 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 :-
This invention has for its object, to facilitate the manufacture of the iron or
steel backs used for strengthening the blades of scythes, reaping hooks and the
like, and it consists briefly in the construction of a machine for rolling the said
backs to the required taper or bevilled form, from a strip of the material.
The annexed drawings represent a machine made according to my invention.
Fig. 1. is a front elevation of machine.

page_text: Fig. 3, end view of sliding table and bed.
Fig. 4, are full size representations of the butt and point of a strip for a 40 inch
scythe back.
Fig. 5, similar representations of the butt and point when operated upon by
machine.
In carrying out my invention I construct a machine consisting of a pair of
housings to carry a top and bottom roll, a sliding bed upon a strong metal frame
which passes between the housings, suitable driving gear with reversing motion to
travel the sliding bed to and fro upon the metal frame, and suitable shaping
blocks.
The machine is illustrated in Figs. 1 and 2, in which A and A2 are a pair of roll
housings, and B, is a strong metal bed frame passing between the said housings and
to which they are preferably secured by bolts.
In the housings I fix a top and bottom, roll C, C², the top roll C, is for rolling
the material to shape, the bottom roll C2, is to support the sliding bed D, and thus
to bear the pressure of the top roll; the faces of the bed frame marked E, upon
which the sliding bed D, moves are thus relieved from the working pressure, which
· otherwise would seriously increase the frictional resistance.
The sliding bed D, is provided with a rack fixed underneath it, and is moved in
either direction by a pinion F, upon a shaft G, driven by the gearing H, or any
other arrangement of driving gear; J, is a clutch for reversing the rotary motion
of the pinion shaft G, by means of the bevil wheels K.
The sliding table D is provided with set screws or like means for holding and
adjusting a rolling block L, upon which the strip of metal to be operated upon is
laid, and upon the block L, an adjustable strip M, is fixed, its function being to
form a fillet or mould N, see Fig. 5, upon the strip or back, and to regulate the
groove in which the strip or back is rolled, to various tapers and widths.
The strip before it is rolled to the finished form is cut tapering in one direction
only as seen in Fig. 4, and as it is required to taper both in its width and in its
thickness towards the point, I use the following means to accomplish this result.
I make the rolling block L, with a portion of its upper surface P, set down and
inclined, as seen in Fig. 3, and this inclined portion, inclines or tapers also longi-
tudinally that is from end to end.
The part thus set down below the face Q of the block L, and bounded by the
adjustable strip M, and the face of the roll C, gives the shape or configuration of
the cross section of the rolled strip or back.
When a strip is to be rolled, the sliding bed D is run out to one end of the bed
frame B, so that the widest part of the groove in block L, is just through the roll;
the heated strip is placed in the groove, the butt end being next the roll, and the
machine being started, the sliding bed D, with the strip is drawn under the roll C,
and the strip is compressed by the roll into the groove, forming it accurately to the
desired shape.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same may be performed or carried into practice, I
declare that what I claim is :-
1-The improved machine for rolling the backs of scythes, hooks and the like,
consisting of a sliding bed D, passing between a pair of rolls C and C², and
supported by a bed frame B; a pair of housings A and A2 to carry the said rolls;
and otherwise constructed substantially as hereinbefore described and shown in
Figs. 1 and 2.
2-In a machine for rolling the backs for scythes, hooks and the like, a rolling
block or bed L, having an inclined or bevilled face P, which is also inclined or
bevilled longitudinally; in combination with an adjustable strip M, which can be so
arranged as to form a tapering groove or matrix, in which the back can be pressed

page_text: by a roll C, substantially as hereinbefore described and as shown in Figs. 2 and 3
of the drawings.
