JAMES CALVIN CAYTON, OF TIIORNTON, TEXAS.
SPECIFICATION forming part of Letters Patent No. 447,759, dated MIarch 10, 1891.
Application filed September 5, 1890, Serial No. 363,980. (No model,)
To all whom it may concern:
Be it known that I, JAMES CALVIN CAYTON,
a citizen of the United States, residing at
Thornton, in the county of Limestone and
5 State of Texas, have invented a new and use-
ful Seeder and Planter, of which the follow-
ing is a specification.
This invention relates to seeders and plant-
ers; and it has for its object to construct a
mo machine which shall be simple, durable, and
inexpensive, and which may be quickly and
easily converted from a corn to a cotton
planter, and vice versa.
The invention consists in the improved con-
I5 struction, arrangement, and combination of
parts, which will be hereinafter fully de-
scribed, and particularly pointed out in the
In the drawings hereto annexed, Figure 1
20 is a perspective view of a seed-planter em-
bodying my improvements. Fig. 2 is a plan
view of the same. Fig. 3 is a longitudinal
vertical sectional view showing the machine
arranged for planting cotton. Fig. 4 is a lon-
25 gitudinal sectional view showing the machine
arranged as a corn-planter. Fig. 5 is a trans-
verse sectional view taken on the line 5 5 in
Fig. 3. Fig. 6 is a transverse sectional view
taken on the line 6 6 in Fig. 4. Fig. 7 is a de-
30 tail view showing the adjustable seed-plates.
Like numerals of reference indicate like
parts in all the figures.
The frame of my improved seed-planter is
composed of the side beams 1 1, between the
35 front ends of which is bolted the rear end of
the tongue 2, which is of sufficient width to
properly space the said side beams. The rear
ends of the side beams are spaced by means
of a cross-bar 3. The rear end of the tongue
40 2 is provided at its sides with notches or re-
cesses 4to accommodate the upper ends of the
bifurcated standard 5, the lower end of which
carries the furrow-opener G. The upper ends
of the arms 7 of said standard are pivotally
45 mounted upon a bolt 8, which extends trans-
versely through the beams 1 and through the
rear end of the tongue. Between the arms 7 of
the standardis pivotally mounted a curved or
segmental bar 9, which extends through a ver-
50 tical slot 10 in the tongue, and is provided
with perforations 11 to receive the pin or key
12, by means of which the standard may be
retained at any desired adjustment. It will
be seen that by this device the furrow-opener
may be readily adjusted at any desired eleva- 55
tion and inclination with relation to the sur-
face of the soil.
The under sides of the side beams 1 are pro-
vided with boxes or bearings 13 for the trans-
verse shaft or axle 14, the ends of which carry 60o
the supporting-wheels 15. Said axle is also
provided with a chain-wheel or sprocket-
wheel 16, mounted adjacent to one of the
17 designates the hopper, which is con- 65
structed of sheet metal and is composed of the
sides 18 and the inclined front and rear pieces
19 and 20. The sides 18 are extended down-
wardly to form the lips or flanges 21, which
are attached to the outer sides of the frame- 70
beams 1, upon the upper sides of which the
hopper rests. The front and rear sides of the
hopper are connected by a downwardly-ex-
tending curved metal plate 22, which fits
neatly between the side beams 1, and is pro- 75
vided with a central longitudinal slot 23.
Suitably mounted upon the axle 14 and ex-
tending into the said slot is a circular disk 24,
which is the seed-disk of my improved planter.
Said disk is provided in its periphery with re- 80
cesses or seed-cups 25, in the bottoms of which
screws 26 are mounted. By adjusting said
screws it will be seen that the sizes of the seed-
cups may be accurately regulated to contain
any desired quantity of seed. Theseseed-cups 85
are used only when corn, peas, or other simi-
lar seed is to be planted. When the device
is. to be converted into a cotton-planter, the
screws 26 are raised until they are flushwith
the periphery of the seed-disk. The latter is 90
then provided with outwardly-extending fin-
gers 27, which are screw-threaded at their
inner ends to engage screw-threaded recesses
28, formed for their reception in the seed-
disk. The latter is preferably constructed 95
of cast-iron, so as to be strong and durable.
The plate 22 in the bottom of the hopper is
provided at the front and rear ends of the
slot 23 with gage-plates 28', having slots 29,
by means of which they are adjustable upon oo
