JOHN S. PURDY, OF HOUSTON HEIGHTS, TEXAS.
Application filed July 5, 1
To all whom it may concern:
Be it known that I, JOHN S. PURDY a Citi-
zen of the United States, residing at Hous-
ton Heights, in the county of Harris and.
5 State of Texas, have invented certain new
and useful Improvements in Picket-Point-
ers, of which the following is a specification.
This invention relates to new and useful
improvements in a picket pointer.
10 The object of the invention is to provide a
device of the character described whereby
the pickets used in the construction or woven
wire picket fences may be sharpened or bev-
eled at one end uniformly and with ease and
With the above another objects in view,
the invention has particular relation to cer-
tain novel features of construction, opera-
tion and arrangement of parts, an example
20 of which is given in this specification and
illustrated in the accompanying drawings,
Figure 1 is a plan view of the device.
Fig. 2 is a side elevation thereof, and Fig. 3
25 is an end elevation thereof.
Referring now more particularly to the
drawings wherein like numerals of reference
designate similar parts in each of the fig-
ures, the numeral 1 refers to a U-shaped
30 casting forming the frame work of the de-
vice and which is adapted to be secured to
a suitable stationary support. Upon the
side of this frame work, near one end there-
of is secured a blade 2. This blade is se-
35 cured in position and may be adjusted in
accordance with the desired angle of the
point of the picket. The other end of the
frame work has a suitable bearing 4 integral
therewith and passing through. this bearing
40 4 is a bolt 5 which also passes through suit-
able holes in the links 6 and 7. These links
are secured in position by means of said
bolt, one end of which has an integral head
and the other end of which has a nut thread-
45 ed thereon. The other, or upper ends, of the
links 6 and 7 embrace the dog 8, one being
arranged on each side and passing through
said ends of said links and also through an
alined bearing in said dog is a bolt 9, one
50 end of which has an integral head and upon
the other end of which is threaded a nut so
as to hold said links in position relative to
said dog. This dog is arranged to oppose
the blade 2 and is spaced a distance there-
5 from and its top facing the blade is provided

with sharp teeth for a purpose to be herein-
after set forth.
A handle 10.is provided, one end of which
is inserted in the socket 11 of the dog 8 and
by means of. which said dog is manipulated. 60
Secured upon the handle near its free end is
a guide plate 12 which can be adjusted for
different lengths of pickets. One side and
the outer .end of this plate is provided with
upstanding flanges numbered respectively 65
13 and 14.
In operation the pickets are placed side by
side, the outer ends resting upon the plate 12
and against the flange 14. The other ends of
these pickets rest upon the dog 8 and project 70
between the same and the blade 2. The han-
dle 10 and the pickets carried thereby are
then forced downwardly so. as to bring the
ends of the pickets against the sharp edge
of said blade, the dog 8 operating upon its 75
pivotal support and the links 6 and 7 oper-
ating upon the bolt 5 as a pivot. The blade
2 is set at such an angle with reference to
the handle 10 that the corners of the pickets
will be cut, off by said blade, and the blade is 80
of sufficient width to cut off all the corners
of the pickets carried by the plate 12. The
position of the pickets is then reversed, the
other edges being placed toward the handle
10, the operation completed and the other 85
corners of said pickets cut off. . In forcing
the pickets against the blade 2 the cutting
edge enters the side of the picket and follows
the are of. a circle whose radius is very
nearly equal to the distance from the pivot 90
point of the bolt 5 to the cutting edge of the
blade 2.. The point of the picket will be the
intersection of two arcs of two equal circles.
The upper side of the dog facing the
blade 2 is provided with ratchet teeth which 95
engage with said pickets and prevent them
from slipping during the operation of the
The link 7 projects upwardly beyond the
bolt 9 and downwardly beyond the bolt 5, 100
the upwardly projecting end of said link,
together with the flange 13 forming side
braces for the pickets during the operation
of the device, and the lower projecting end
of said link 7 limiting the rearward move- 105
ient of the handle 10 by coming in contact
with the lug 15, projecting outwardly from
the frame work 1. Projecting laterally from
the frame work 1 is a bearing member 16
which has a tapped hole extending there- 1
