WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake and Co, Patent
Agents, Southampton Buildings, London, "IMPROVEMENTS IN THE MANUFACTURE
OF HAND-RAKES [A communication to him from abroad by Theodor Carlsson,
of Eskilstuna, Sweden]
"
This invention relates to hand-rakes for garden and field use, and to an
improved method of constructing the same.
According to the said invention the rakes are manufactured as follows, that is
to say, I provide a plate of iron or steel out of which the rake is stamped; the
said plate must be of such a size that two rakes can be formed at one and the
same time, the part of the plate stamped out in order to form the teeth of one
rake serving for the teeth of the other rake-After the plate is thus stamped the
teeth are bent into the desired form. Along the back of the rake is provided a
rib or fold which serves to considerably strenghten it. The back of the rake may
also be more or less bent, or quite straight. The shaft or handle socket is conical
in shape and at its top end is provided with two wings so formed, that their lower
sides shall correspond with the back of the rake, to which they are secured by
means of rivets. The teeth of the rake are so bent that the strongest section
thereof is turned in the direction of the strain, a greater solidity being thereby
obtained. The teeth when stamped out are not square with the back of the rake
but at an angle. It will be understood that this angle may be varied according
to the width of the teeth and the interspaces required

HAND RAKES A communication to me from abroad by Theodor Carlsson, of
Eskilstuna, Sweden

This invention relates to hand rakes for garden and field use, and to an
improved mode of constructing the same.
In the accompanying drawing
Figure 1 is a plan of a plate from which the improved rake is stamped.
Figure 2 is an elevation of a rake constructed according to this invention.
Figure 3 is a plan of the same
Figure 4 is a section-on-the line as a Figure 3.
-
According to the present invention I provide a plate of iron or steel of the form
shown in Figure 1 out of which the rake is stamped. The said plate must-be-
of such a size that two rakes can be formed at one and the same time, the part of
the plate stamped out in order to form the teeth of one rake serving for the
teoth of the other rake, that is to say, the teeth f1 belonging to the rake A¹
form the spaces between the teeth f of the rake A. After the plate is thus
stamped the teeth are bent into the desired form as shown in Figure 2.
Along the back of the rake is a rib or fold as shown in Figure 4. This rib
serves to considerably strengthen the rake. The back of the rake may also be
more or less bent as shown in Figure 3, or quite straight.
The shaft or handle socket a is conical in shape and at its top end is provided
with two wings b b which are so formed that their lower sides shall correspond
with the back of the rake, to which they are secured by means of rivets.
The teeth of the rake are bent as shown in Figure 3 so that the strongest
section of the said teeth is turned in the direction of the strain, a greater solidity
being thereby obtained.
The teeth when stamped out are not square with the back of the rake but at an
angle, and this angle may be varied according to the width of the teeth and the
interspaces required.
Having thus fully described the said invention as communicated to me by my
foreign Correspondent and the manner of performing the same I wish it understood
that I claim
First In the manufacture of hand rakes, cutting both the back and teeth
thereof out of one plate in such a manner that two rakes are obtained from the
same, the teeth of one rake being formed of the material stamped from the said
plate in forming the teeth of the other rake.
Second-A rake, the back and teeth of which are formed from the same piece
of metal, substantially as, and for the purpose, set forth.
Third A rake constructed as above described, the back of which is provided
with a rib, substantially as, and for the purpose, specified.
In witness whereof I the said William Robert Lake have hereunto set my
hand and seal this eighth day of August in the year of our Lord One thousand
eight hundred and eighty three.
