PROVISIONAL SPECIFICATION..
Machine for Shaping the Blades of Toy Shovels in Wood.
SYDNEY CHEELD Waterside Chesham, Engineer, WALTER BATES Chesham
Bois, Woodenware Manufacturer, both in the County of Bucks do hereby declare
the nature of this invention to be as follows :--
Our machine consists of a table carrying a cutter spindle in suitable bearings.
By means of a compound lever and claw the shovels can be securely held and
traversed over the cutters.
We sometimes use a clutch handle connected so that the claw may be released
at will.

COMPLETE SPECIFICATION.
Machine for Shaping the Blades of Toy Shovels in Wood.
We SYDNEY CHEELD of Waterside, Chesham, in the County of Buckingham,
Engineer, and WALTER BATES of Chesham Bois, also in the County of
Buckingham, Woodenware 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 relates to a machine for shaping the blades of wooden toy shovels.
The blades of shovels of this kind have hitherto been shaped by means of a spoke-
shave or similar tool operated by hand and our invention is devised for the purpose
of shaping the blades more quickly and at a less cost than when they are shaped
by a hand tool as heretofore."
In the accompanying drawings
•
Figure 1 is a plan and Figure 2 a side elevation of a machine constructed in
accordance with this invention.
The same letters of reference are used to indicate the same parts in the
two views.
G is a table of any ordinary or approved construction carrying a cutter spindle A
supported in bearings on the underside of said table, and rotated at a high velocity
by any suitable means. J is a slotted frame which is secured to the table G by
means of bolts K so as to be capable of lateral adjustment according to the width
of the shovels to be shaped. To the slotted frame J a hand lever C is pivotted
at. C said lever being free to turn on its pivot inwards towards the cutter spindle A,
a stop, not shewn in the drawings, being provided to prevent it from passing
outwards beyond the vertical position shewn in Figure 2. F is a bell crank lever
centred at on the upper end of the band lever C and connected by the link L
to the claw lever B pivotted at B' on the lever C; and E is a spiral or other
spring connected at one end to the claw lever B and at the other to the table G,
and tending to keep the said claw lever and its connections in the position shewn
in Figure 2. To the side of the claw lever B is secured a bar N which rests upon
a guide rail M fixed to the table G whereby the claw lever is caused to travel in a
straight line clear of the cutters as and when it is traversed over the cutter
spindles. Preferably the lower end of the claw lever B is toothed or serrated as
shewn at 6 Figure 1, or otherwise formed or shaped for the purpose of gripping or
biting into the material of the shovel blade and on the back thereof.

page_text: The machine operates in the following manner; the shovel blank is placed in
the machine with its bottom end pressed against the stop D, which may be made
adjustable to suit blades of varying lengths, and with its back upwards and its front
towards the cutter spindle. The lever C is then pulled forward until it presses on
the back of the blank which it then traverses across the cutters at an uniform
height thereabove whereby a groove of uniform depth is cut in the front of the
blank thus forming the shaped blade. The cutters begin their cut just below the
junction of the handle with the blade so that the uncut upper end of the blade
forms the shoulder of the shovel, and the cutters may be so formed that the
commencement of the groove is of a curved shape. It will be understood that by
reason of the pivots and B¹ the claw lever B has a compound motion and that
'the bar N will travel along the guide rail M. When the blade has been traversed
across the cutters the lever C is released, the blade is then drawn off from or
leaves the claw lever B and the spring E returns the parts to their initial position.
Should it be desired to remove the pressure of the claw lever B from the blade at
any time during its traverse across the cutters the free end of the bell crank
lever F is clutched to the lever C and by means of the link L the claw lever B is
raised thus releasing it from the blade.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is: :-
1. A machine for shaping the blades of wooden toy shovels, comprising a fixed
bed or table carrying a rotating cutter spindle, with a claw having a compound
motion for traversing the blade blanks in a straight line across the cutters, arranged
and operating substantially in the manner and for the purposes hereinbefore
described and illustrated in the accompanying drawings.
2. In a machine for shaping the blades of wooden toy shovels wherein the blade
blanks are traversed over the cutters on a rotating cutting spindle, means such as
herein described for holding the blade blanks to and for traversing them across the
cutters, comprising a claw lever pivotted on another lever jointed to a frame
adjustably secured on the machine base or table so that the claw partakes of the
compound motion of the two levers, the guide bar on the claw lever sliding over
a guide rail secured to the machine base or table whereby the claw lever is caused
to travel in a straight line across the cutters said claw lever being spring controlled
and linked to a bell crank lever whereby it can be raised so as to disengage it
from the blade blank when so desired substantially as described and illustrated in
the accompanying drawings.
3. The combination of parts forming our machine for shaping the blades of
wooden toy shovels arranged so as to operate substantially in the manner and for
the purposes described and illustrated in the accompanying drawings.
