Venetian Blind Laths, Mouldings, or other similar Work..
I JOHN KERSHAW of Brow Mill, Clayton near Bradford in the West Riding of the
County of York, Reed and Heald Manufacturer, do hereby declare the nature of my
invention for IMPROVEMENTS IN MACHINES FOR PLANING REED RIBS, HEALD
SHAFTS, VENETIAN BLIND LATHS, MOULDINGS OR OTHER SIMILAR WORK to be as
follows
I employ an Iron, Wood, or other plane, which may be of the ordinary form of
construction, or constructed specially to suit the arrangement of my machine, and
which may be placed in an inverted or other position suitable for the work to be done:
this plane is balanced on pivots on one arm of a lever and is held in position by a
weight, spring or other contrivance attached to the other arm of the sanie lever, or by
any adjustable mechanical contrivance. I employ adjustable screw or screws and
plates for the purpose of adjusting the plane to suit the thickness or form of the wood
to be planed. The cutting edge of the plane iron may be flat, concave, convex or any
other form suitable to the work to be done. For carrying the wood forward as it is
planed I employ adjustable carrying rollers and guides.

1 JOHN KERSHAW of Brow Mill, Clayton near Bradford in the West Riding of the
County of York, Reed and Heald Manufacturer, 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 improvements in apparatus and means employed in
planeing Reed Ribs, Heald Shafts, Venetian Blind Laths, Mouldings or other similar
work. To accomplish this I employ an Iron, Wood or other plane which may be of
the ordinary form of construction, or constructed specially to suit the arrangement of
my machine, and which may be placed in an inverted or other position suitable for the
work to be done. This plane is balanced on pivots on one arin of a lever and is held
in position by a weight, spring or other contrivance attached to the other arm of the
same lever, or by any adjustable Mechanical Contrivance.
I employ adjustable screw or screws and plates for the purpose of adjusting the
plane to suit the thickness or form of the wood to be planed. The cutting edge of the
plane iron may he flat, concave, convex or any other form suitable to the work to be
done. For carrying the wood forward as it is planed employ adjustable carrying
rollers and guides.
And in order that my invention may be fully understood I describe the
accompanying diagrams as follows:-Figure 1. is a front elevation. Fig. 2
an end elevation, and Fig. 3 a plan of the working parts of the Machine, and
the lettering in each corresponds to that of the others. A is an Iron, Wood or other
plane, either of the ordinary form of construction, or constructed specially to suit the
arrangement of the machine or to meet the requirements of the work to be done, B is
a lever which may be bent in the form shown here or otherwise, and at one end of
which the plane A. is balanced on a pivot, spindle or other suitable arrangement, and
the plane is kept in position for the work it has to accomplish by means of weights or
springs at the opposite end of the lever B. C. represents the line, surface, or bed upon
which the Reed Rib or other work travels, and D and D¹ the carrying and delivery
rollers respectively. E represents the fly wheel of the machine, and F (Fig. 3) the
driving gearing communicating direct from the driving spindle or shaft of the
machine. G and G are the fast and loose pulleys respectively by means of which
power is communicated to the machine, and H is the belt fork lever to be used for
starting and stopping the machine at will. I. 1 are adjustable screws employed for
the purpose of adjusting the plane to suit the thickness or form of the wood to be
planed. In conjunction with these screws I may employ plates or other similar

page_text: contrivance to.suit the character of the work. I also employ in connection with the
carrying and delivery rollers D. D' adjusting screws or springs K.
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 :-
The use or employment of an ordinary or specially constructed plane, or any
number of planes, balanced on pivots or spindles, and kept in position by a lever or
other similar means as herein set forth, and the use or employment of feed and
delivery rollers and the other appliances necessary as hereinbefore described, and that
by this means I can accomplish a greater amount of work than has hitherto been done
by any known machine employed for the purpose.
In witness whereof I, the said John Kershaw have hereunto set my hand.
JOHN KERSHAW.
