ROBERT LITEL JACKSON, OF McKINNEY, TEXAS.
PLOW-SCRAPER.
SPECIFICATION forming part of Letters Patent No. 563,378, dated July 7, 1896.
Application fled October 2, 1895, Serial No, 564,424, (No model,)

To all whom it may concern:
Be it known that I, ROBERT LITEL JACKSON,
a citizen of the United States, residing at Mc-
Kinney, in the county of Collin and State of
5 Texas, have invented a new and useful Plow-
Scraper, of which the following is a specifica-
tion.
My invention relates to plow-scraping de-
vices, and has for its object to provide a sim-
io ple, inexpensive, and efficient attachment so
arranged as to be normally held in operative
relation with the moldboard of a plow, where-
by it may be depressed at any time and with-
out checking the movement of the plow to
z5 scrape accumulated soil from the surface
thereof.
Further objects and advantages of this in-
vention will appear in the following descrip-
tion, and the novel features thereof will be
20 particularly pointed out in the appended
claims.
In the drawings, Figure 1 is a side view of
a scraper constructed in accordance with my
invention applied in the operative position
25 to a plow. Fig. 2 is a detail view of the
scraper detached.
Similar numerals of reference indicate cor-
responding parts in both figures of the draw-
ings.
30 The shank 1 of the scraper embodying my
invention consists of a spring-metal bar ter-
minating at its lower end in a blade 2, which
is arranged in contact with the operating-
surface of the moldboard 3 of a plow, the
35 shank being provided, as shown in Fig. 2,
with a normal bend or curve, which causes
the blade to bear firmly and with a uniform
pressure upon the surface of the moldboard.
The guides 4 and 5, which are attached to the
40 standards 6 of the plow, maintain the shank
of the scraper in position, and they are so
arranged with relation to each other as to in-
sure the positive pressure of the blade against
the surface of the moldboard. The shank
45 terminates at its upper end in a lateral pro-
jection or handle 7, which may be grasped
by the operator in order to depress the de-
vice and thereby cause the blade to traverse
the moldboard.
5o Theshank is provided belowthe lowermost
guide with a stop-pin 8, adapted to engage
said guide and check the upward movement
of the scraper, and in the construction illus-

trated the upper edge of the blade of the
scraper conforms or corresponds in configu- 55
ration with the corresponding upper edge of
the moldboard, whereby when the scraper is
elevated, as shown in Fig. 1, the blade thereof
lies snugly against the surface of the upper
end of the moldboard, and is flush at its up- 6o
per edge therewith, to avoid breaking the
surface of the moldboard or offering any ob-
struction to the passage of the soil in travers-
ing the same.
Various changes in the form, proportion, 65
and the minor details of construction may be
resorted to without departing from the spirit
or sacrificing any of the advantages of this in-
vention.
Having described my invention, what I 70
claim is-
1. A scraper for plows having a spring-
metal shank adapted tobe mounted in guides
upon the standard of the plow and terminat-
ing at its lower end in a blade to traverse the 75
surface of the plow, said shank having a nor-
mal bend which forces the blade tightly
against the surface of the plow and maintains
the scraper by friction at any desired adjust-
ment, substantially as specified. 80
2. The combination with a moldboard of a
plow, of fixed guides adapted to be supported
by a plow-standard, a spring-metal shank
having a normal bend mounted to slide in said
guides and provided with a stop-pin to limit 85
its upward movement, said shank terminat-
ing at its lower end in a blade to traverse the
surface of the moldboard and at its upper end
with a handle, the shank being held from ac-
cidental sliding movement by frictional con- 9o
tact with the guides at any desired adjust-
ment, said frictional contact being caused by
the tendency of the shank to assume a posi-
tion different from that in which it is held
by the guides,and the blade being constructed 95
to correspond in contour with the contiguous
end of the moldboard and to lie in close con-
tact with the surface of the same, substan-
tially as specified.
In testimony that I claim the foregoing as ioo
my own I have hereto affixed my signature in
the presence of two witnesses.
ROBERT LITEL JACKSON.
