IMPROVEMENTS IN ATTACHING NUTS TO SPOKESHAVES AND OTHER ARTICLES
Year: 1885

page_text: I CHARLES MARPLES of 119 Carver Street Sheffield in the County of York
Joiners Tool Manufacturer do hereby declare the nature of my invention for
IMPROVEMENTS IN ATTACHING NUTS TO SPOKESHAVES AND OTHER ARTICLES and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, that is to say:-
My invention of an improved method of attaching or securing the nuts of
screw tang spokeshaves to the stock of the tool, has for its object, to accomplish
the same in a simple and inexpensive manner, the same method may also be used
for attaching or securing similar Nuts to other articles such as scribing Gauges,
Skates, and similar articles.
In Spokeshaves to which my invention is particularly applicable, the nuts to be
secured, are the wing nuts that fit upon the screwed tangs of the blade or cutter,
and used for the purpose of adjusting and regulating the distance of the cutter
from the stock, to accomplish this the nuts must be secured to the stock in such a
manner that they can be turned round upon the screwed tangs of the cutter.
And in order that my invention may be fully understood I annex hereto a sheet
of drawings illustrating the method of its application to a Spokeshave.
Fig. 1 represents a spokeshave to which my invention is applied, part being
shown in section.
Fig. 2 shows the hole in the stock in section.
Fig. 3, plan of hole in the stock.
Fig. 4, the wing nut.
A is the "Stock" of a Spokeshave, B is the Cutter, C is the screwed tang,
D, D, are the Wing Nuts, the upper part of which may be made of any suitable
form, having a collar E, to rest against the stock A, under the collar is a neck F,
terminating with two ears or lugs G, G, which may be solid with, or attached
to the nut in the manner shown.
The top part of the hole H, through which the screwed tang passes, is bored out
to suit the neck F, of the nut, and an annular recess I of larger diameter is formed
to receive the lugs G, G, the remainder of the hole is made to receive the tang C,
and end of the blade or cutter B.-To get the lugs G, into the recess I, through
127

page_text: the smaller opening H, I adopt the simple means of cutting a slot or gate K, in the
side of the hole H, to admit one of the lugs G, and enable it to be passed through
into the recess.
To place the nut in position (which is done before the tangs of the cutter are
placed in the stock) it is necessary to turn it on one side, and insert one of the
lugs G, into the annular recess I, on the side opposite to the slot K, the other lug
may then be passed down the slot and turned round into the recess.
When both nuts are in their places, the screwed tangs of the cutter are inserted
and the nuts screwed upon them.
Although the ears or lugs are brought opposite to the slot K, in every half turn
of the nut, it is impossible for them to be withdrawn or forced out, as the nut
being screwed upon the tang, it cannot be turned sideways, which is the only
position in which the nut can be taken from the stock.
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
1st The method of attaching or securing the nuts of spokeshave tangs to the
stocks, for the purpose specified and substantially as hereinbefore described and
illustrated.
2nd The method of securing the nuts of screws to Skates, Carpenters Scribing
Gauges, and other tools or articles substantially as herein before described and
illustrated.
