JAMES EDWARD BULLOCK, of Oxford, in the Province of Ontario, in the Dominion
of Canada. "IMPROVEMENTS IN SKIMMER ATTACHMENTS TO PLOWS."
The first part of this Invention relates to a malleable cast or wrought iron frame,
through which a socket is formed to receive the coulter of a plow, and on to which
the frame is adjusted and secured by means of a set screw. The frame being so
constructed as to form a horn-shaped knife at the top or antichoker, preventing the
choking of the stubble or other material under the beam of the plow; the lower
portion of the frame forms a plate, through which there is an oblong hole allowing
the adjustment of a bolt passing through it, by means of which a combined mould
board and share is securely fastened to the frame.
The second part of this Invention relates to the attachment of the combined
mould board and share with the frame, and the combination of the land skimmer
so formed with the coulter of a plow.
Figure 1 is a side elevation of a plow with the land skimmer attached to the
coulter thereof.
Figure 2 is a side elevation of the land skimmer complete.
Figure 3 is a plan of the frame.
Figure 4 is a plan of the combined mould board and share.
Similar letters of reference denote the same parts of the Invention and the means
by which the several parts are combined.
a is the coulter of the plow; b is the socket in the frame c, through which the
coulter a passes, and by means of the frame c is adjusted and secured thereto by
the set screw f; c, the malleable cast or wrought iron frame, which can be raised or
lowered on the coulter a according to the depth the plow is required to run in the
soil; d, the combined steel mould board and share, which is fastened to the frame c
by means of the screw bolt e; e, the screw bolt for the purpose above described;
f, the set screw, by means of which the frame c can be raised or lowered on the
coulter a for the purpose described in reference to c; g, the antichoker, combined

other material from choking the operation of the plow; h, the oblong hole or slot in
the frame c, by means of which the bolt e can be so adjusted as to allow the mould
board d to fit securely to any part of the coulter a.
The advantages to be derived from this Invention are the following:-
1st. Much lighter draft, the plow more easily held and guided, and the work
done in a thorough and husbandry like manner than in the attachment of the
skimmer direct to the beam of the plow and in front of the coulter.
2nd. The improved skimmer attachment can be attached to the coulter without
interfering with the construction of the flow.
3rd. It can be used either with or without a set wheel gauge.
4th. It produces less leverage on the beam of the plow from its close proximity
to the body of the plow, and thereby throwing the strain on it.
5th. Its cheapness of construction and ready adjustment.
