WILLIAM B. BRACEWELL, OF COTTON, TEXAS.
PLOW ATTACHMENT.
SPECIFICATION forming part of Letters Patent No. 664,527, dated December 25, 1900.
Application filed August 4, 1900. Serial No, 25,902. (No model,)To all whom it imay co;cerm:
Be it known that I, WILLIAM B. BRACE-
WELL, a citizen of the United States, resid-
ing at cotton, in the county of Grimes and
5 State of Texas, have invented a new and use-
ful Plow Attachment, of which the following
is a specification.
The present invention relates to im prove-
inents in plows, the object being to provide
10 an attachment in the form of a shoe that may
be applied to any ordinary plow and which
is adapted to run longitudinally in the fur-
row, loosening the earth in front of the sweep
and forming a bearing-surface, with a result-
15 ing steadiness in the movement of the plow,
and whereby the draft strain is greatly de-
creased.
One of the particular objects is the provi-
sion of novel means for securing the shoe in
20 place, said securing means being adjustable
in order that the attachment may be applied
to different styles of plows and the position
of the shoe on the plow changed as desired to
meet the different kinds of work.
25 In order that the invention may be readily
understood by those skilled in the art, the
preferred form is illustrated in the accompa-
nying drawings and described in the follow-
ing specification, of which the said drawings
30 form a part.
In the drawings, Figure 1 is a perspective
view of an ordinary shovel-plow, showing the
improved attachment placed thereon. Fig.
2 is a perspective view of the same looking
35 in an opposite direction. Fig. 3 is a longitu-
dinal section. Fig. 4 is a detail perspective
of the shoe. Fig. 5 is a detail perspective of
the angle-bracket.
Similar n umerals of reference designate cor-
4o responding parts in the several figures of the
drawings.
In order that the application of the device
may be clearly understood,an ordinary shovel-
plow is illustrated, of which 10 designates the
45 beam; 11, the standard, which comprises a
pair of spaced arms whose upper ends em-
brace the beam, and 12 the shovel-sweep or
moldboard, secured to the lower end of the
standard 11.
50 The improvement comprises a furrow shoe
or slide 13, secured to the lower end of the
plow by means of the angle-bracket 14. Theshoe 13 consists of a metallic bar rectangular
in cross-section and having at one end the
backwardly-extending upturned lip 15, that 55
is slightly curved and forms a notch 16, in
which the point of the plow is secured. This
end of the shoe is broadened slightly and is
pointed, forming a nose which works in ad-
vance of the shovel and loosens the earth and 6o
roots. In order to strengthen the point of
the shoe, a rivet 17 is arranged vertically
through the shoe and lip at their points of in-
tersection, thus obviating any liability of
breaking at this point. . The shoe is also pro- 65
vided with a pair of bolt-holes 18, which pass
vertically through the same and receive bolts
19, by means of which the shoe is secured to
the angular bracket 14. The angular bracket
14 comprises a metallic bar having a longitu- 70
dinal slot 20 and bent to form a pair of arms
21 and 22, which are adapted to conform to
and rest against the back of the standard and
the upper surface of the shoe 13, respectively.
The bolts 19 pass through the slot of the arm 75
22, and nuts 23, arranged upon said bolts, en-
gage the upper surface of the arm, and there-
by clamp the shoe rigidly to the same. A
bolt 24 is arranged to pass through the slot of
the arm 21 and through the standard 11. 8o
Preferably the same bolt that fastens the
shovel is used for clamping the arm to the
standard.
In applying the device the point of the
plow is arranged in the notch 16 and the an- 8J
gle-bracket is adjusted upon the shoe until
the arm 21 rests against the standard. The
nuts 23 are then tightened. By this means
it will be seen that the shoe may be applied
to different sizes and styles of plows. In or- 90
der that the depth of penetration of the plow
may be regulated, the angle of inclination of
the shoe may be readily changed by adjust-
ing the arm 21 upon the standard. This is
done by loosening the nut of the bolt 24, 95
whereupon the slot 20 will allow the arm to
be raised or lowered, as desired.
From the foregoing it is thought that the
construction, operation, and many advan-
tages of the herein-described plow attach- 100
ment will be readily apparent to those skilled
in the art without further description, and it
will be understood that various changes in
the form, proportion, and minor details of
