Specification of Letters Patent Ho. 53, dated October 15, 1836. 

To all whom it may concern : 

Be it known that I, Samuel Clime, of 
Bucks county, Pennsylvania, have invented 
a combined plow, being a machine for plow- 
5 ing in light free soil, for plowing in grain, 
dressing Indian corn, and all other light 
work of similar kind. 

The principle of combination on which 
the due construction of the machine depends 

10 is to place the line of draft, or beam so that 
the resistance to be overcome may bear 
equally on each side of that line. To effect 
this purpose the transverse beam or rest to 
which the several plows are attached is f as- 

15 tened to the beam precisely in the middle of 
the transverse beam, and having the center 
plow immediately under the point of inter- 
section. The other plows are then placed 
equidistant on each side of the beam. This 

20 disposition brings the beam of the plow 
very nearly in the line of equal resistance, 
the middle plow becomes a center of motion, 
or fulcrum in which the whole machine bal- 
ances, and adds greatly to the strength of 

25 the apparatus, and the firmness of its parts. 
The transverse beams cross the beam of the 
plow at an angle of forty five degrees thus 
placing the right hand plow as much before 
the next succeeding one as it is removed at 

30 a right angle on one side and thereby giving 
the greatest possible room, or space with the 
least length of beam. For the same reason 
the length of the sole of the plow should 
not much exceed its extreme breadth. The 

35 proportions used, and found convenient, are 
about ten inches in length by eight in 
breadth, and the turn of the mold board 
should be very little beyond a perpendicular 
from the hinder corner of the share. 

40 The plows consist simply of a mould- 
board, landside, and sheath, or standard. 
The mold board is drawn, flattened out at 
the lower edge so as to supply the place of 
a share, or wing. These should all be of 

45 iron either hammered, and rolled, or cast 
at the pleasure of the maker, and fastened 
into the transverse beam by the standard 
with a shoulder on the under side of the 
beam fitted to an iron collar, or codrill, and 

a screw or nut or strong wedge on the top 50 
of the beam. The standards are made one 
foot in height, and the draft, or depth of 
the plow is given by elevating the forward 
end of the beam about one inch the whole 
length of the beam being five feet. The 55 
hinder end of the beam is fastened in a piece 
of timber crossing it at right angles hori- 
zontally, and meeting a similar piece of tim- 
ber laid parallel with the beam, and both of 
them fastened in the transverse beam so as (50 
to brace the whole framework, and to form 
a rest for the stilts, or handles of the plow. 

The machine is found to work well with 
plows of eight inches in breadth placed at 
the distance of fourteen inches from each 65 
other, thus cutting about ten inches each, 
and using five plows. Two horses are able, 
to work this combined plow quite easily, and 
to pass over as much land in a day as three 
teams of two horses each with a common: 70 
single plow. 

To construct a combined plow, draw a 
right line A, B, for the beam about five feet 
in length. Draw another line C, D, for the 
transverse beam at an angle of forty five de- 75 
grees with the former cutting at A, B, at 
a convenient distance from the hinder end, 
say fifteen inches, and carry C, D, with the 
right end forward to equal distances on each 
side of A, B, making the whole length of 80 
C, D, for five plows, say four feet eight 
inches, for three plows two feet four inches, 
and in proportion to the number, and size 
of the plows intended to be used allowances 
must be made in these measurements for the 85 
ends, and fastenings, the bracing and han- 
dles may be made of any form to please the 
maker, and combining strength with light- 
ness of material. The transverse beam 
should be made of good white oak timber, 90 
not less than four inches deep, and having 
rivets well fastened passing horizontally 
through it at each end, or one inch at each 
side of each standard.
