EDWIN M. REESE, OF DALLAS, TEXAS.
COMBINED PLOW AND SCRAPER.Specification of Letters Patent. Patented Aug . 26,1913.
Application filed June 3, 1912. Serial No. 701,157.To all whom it may concern:
Be it known that I, EDWIN M. RESE, a
citizen of the United States, residing at
Dallas, in the county of Dallas and State of
5 Texas, have invented certain new and use-
ful Improvements in Combined Plows and
Scrapers, of which the following is a specifi-
cation.
My invention relates to new and useful
10 improvements in plowing and scraping ma-
chinery, and more particularly to combina-
tions of plows and scrapers.
The object of my invention is to provide
a combined plow and scraper, which may be
15 employed to alternately break or loosen a
surface that is being graded or lowered, and
to scrape the loosened material from said
surface.
A further object is to provide a combined
20 plow and scraper, in which the means for
plowing and the means for scraping are
connected in a rigid relation, the construc-
tion being such that the plowing means may
be operative during travel of the machine in
25 one direction, and the scraping means op-
erate during travel in the reverse direction,
a change in the working positions of the
parts being automatically effected when the
direction of .the travel is reversed.
30 The object of the invention is finally to
provide a device of the character described,
that will be simple and durable in construc-
tion and efficient in operation, and one, the
various parts of -which will not be likely to
35 get out of working order.
These objects are accomplished by the
construction illustrated in the accompany-
in drawing, wherein; v
Figure 1 is a plan view of my combined
40 plow and scraper. Fig. 2 is a view of the
same in side elevation, showing the position
assumed by the parts when the machine is
acting as a plow. Fig. 3 is an end view of
the machine, drawn to an enlarged scale.
45 Fig. 4 is a vertical sectional view of that ex-
tremity of the implement, upon which the
working parts are mounted, the section be-
ing taken upon the line a3--x of Fig. 1.
Fig. :-is a fragmentary vertical sectional
50 view of the same portion of the implement,
the section being taken upon the line y-y
of Fig. 1..
In the drawing, similar reference charac-
ters are employed to designate similar parts
55 in all the figures.The numeral 1 denotes a pair of elon-
gated parallel beams, which are rigidly
connected by a. number of transverse bars
2 and by a pair of diagonal intercross-
ing brace members 3. The beams 1 will 60
preferably be of wood, and the members 2
and 3 of steel, the former member being an-
gular in cross-section and the latter round.
The members 1, 2, and 3 together form a
rectangular frame, upon one extremity of 65
which the plowing and scraping means are
supported. At said extremity of the ree-
tangnlar frame, a pair of opposite clamping
brackets 4 are mounted upon the beams 1,
and said brackets rigidly hold the extremi- 70
ties of a cylindrical rod 5, transverse with
the frame. A large rectangular metallic
plate 6 is mounted upon the rod 5, its up-
per and lower edges being parallel to said
plate, and substantially equidistant there- 75
from. The connection between said plate
and the rod 5 is formed by a plurality of
brackets 7, mounted fast upon one side of
the plate, through which brackets the rod
is passed. The plate 6 is adapted to un- 80
dergo a limited angular displacement about
the axis formed by the rod 5, and a descrip-
tion will now be given of certain means em-
ployed to limit such displacement.
Directly above each clamping bracket 4, 85
there is mounted a bracket 8 of inverted V
shape, having its feet equally spaced from
the underlying member 4 upon the corre-
lated beam 1. Upon the apices of the
bracket 8, are mounted fast the extremities 90
of a bar 9, angular in cross-section, and
transverse in relation to the aforesaid rec-
tangula.r frame. The height of the bar 9
above the rod 5 is such that the upper edge
portion of the plate 6 will contact with said 95
bar when the plate assumes a position
slightly removed from the vertical, as shown
in full lines in Fig. 4 of the drawing. Thus
it will be seen that the member 9 acts as a
stop-bar and determines one of the limiting 100
positions of the plate 6. Another stop-bar -
is formed by a member 10, parallel to the
bar 9, having its extremities mounted fast
upon opposite legs of the two brackets 8.
When the pate 6 is in the limiting position 105
determined by its contact with the bar 10,
said. plate forms an angle with the ground
somewhat less than 45 degrees, as is clearly
indicated by dash lines in Fig. 4.
A short distance above its lower edge, the 1101,0171,176.
