I claim:
1. An adapter apparatus for use with a conventional bucket having
side walls, back wall and a bottom wall presenting an open end
bucket; comprising an elongated thin support member with spaced end

the bucket; certain ones of said prong members extending rearwardly
from said support member and having portions that lie in abutting
contact with the bottom wall of said bucket; the remaining ones of
said prong members having their rearwardlymost portion secure to
said elongated support member; and means for connecting said
certain ones of said prong members to the bottom wall of a
bucket.
2. An adapter apparatus as set forth in claim 1 wherein said
rearwardly extending portions of said certain ones of said prongs
are bifurcated for contacting the upper and lower surfaces of the
bottom wall.
3. An adapter apparatus for use with the conventional bucket of a
tractor comprising an elongated narrow support member having a
longitudinally extending planar surface for abutting contact to the
edge of the bucket, said support member having a plurality of
prongs extending at right angles outwardly therefrom, said
outwardly extending prongs being elongated members tapering to a
point, certain ones of said prongs having bifurcated portions
extending rearwardly from said support member in a direction
opposite to said outwardly extending direction, and connecting
means on said rearwardly extending bifurcated portions of said
certain ones of said prongs for interconnecting said certain prongs
to the bucket.
Description
BACKGROUND OF THE INVENTION
This invention relates to an adapter apparatus for use with a high
lift bucket and more particularly to an adapter apparatus which
converts the conventional bucket of a high lift or the bucket of
the usual farm tractor to do a specialized job for lifting and
loading loose materials such as barnyard fertilizer or hay.
In the use of high lifts and farm tractors for conventional purpose
work, the design has been such as to emphasize utility and
applicability; however, it has become the practice to use these
devices for as many odd jobs as possible to enhance their
usefulness. In order to provide greater adaptability, manufacturers
of high lifts and farm tractors have designed special use buckets
which require the removal of one bucket and the mounting of the
special purpose bucket. After such special use, it is necessary to
again reverse buckets, which requires time, energy, and the expense
of maintaining at least two buckets and their storage. The changing
of the buckets is not an easy task. One special bucket which
manufacturers have provided is one with long prongs which are
useful in the handling of loose materials such as barnyard
fertilizer. In the case of such loose materials, the conventional
bucket is ineffective to pick up loose materials since the straw
throughout interferes with its effective pick-up by the straight
edges of the bucket. The weight of such loose material is
sufficiently light that an ordinary bucket just pushes it and
cannot effectively pick it up.
SUMMARY OF THE INVENTION
The present invention is directed to an adapter apparatus that is
inexpensive to fabricate yet rapidly converts the conventional
bucket of a farm tractor or high lift to a special purpose bucket.
The adapter comprises a plate member that is conveniently connected
to the conventional bucket, which plate member has a plurality of
spaced prongs which extend outwardly away from the bucket when the
plate member is firmly secured to the edge of the bucket.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is an isometric view of the bucket adapter apparatus of a
preferred embodiment of the invention, with the bucket shown in dot
and dash lines;
FIG. 2 is a cross-sectional view of the bucket adapter apparatus
taken on lines 2--2 of FIG. 1;
FIG. 3 illustrates a modification of the adapter apparatus;
FIG. 4 illustrates a further modification of the adapter
apparatus.
DETAILED DESCRIPTION
Referring now to the drawings, wherein like reference characters
designate like or corresponding parts throughout the several views,
there is shown in FIG. 1 a coventional bucket 10 of a farm tractor
or high lift in phantom lines having a rear wall 11, side walls 12
and a bottom wall 13. Such bucket 10 is of conventional shape and
can be removably mounted to the lever members of a tractor which
manipulates the bucket in its operation.
The adapter apparatus which can be attached to such conventional
bucket includes a flat plate member 15 which extends the full front
end of the bucket and is adapted to abuttingly engage the front
edge of the bucket 10.
Secured to the plate member 15 as by welding are a plurality of
spaced prongs 16. FIG. 1 discloses three prongs 16, although more
or less of these prongs may be used. The rear portion of each prong
16 is bifurcated, providing a slot 17 which facilitates the
attachment and support of the adapter to the bottom wall 13 of the
bucket. The rearward portion of each prong 16 has a bore which is
in alignment with a bore on the bottom wall 13 of the bucket, such
that a threaded bolt or stud 19 extending therethrough facilitates
the securing of these parts together. The forward portion of each
prong 16 tapers to a point 18. Suitably secured to the plate member
15 are a plurality of additional prongs 20, which prongs 20 are
similar in all respects to prongs 16 except that their rearwardly
disposed bifurcated portion extends rearwardly sufficiently to have
their rear edges 21 flush with the rearwardly most edge of the
plate member 15. The forwardmost portion of prongs 20 terminate
into a point 18 as prongs 16. Such prongs 20 may have their
bifurcated portion extend rearwardly sufficiently to engage the
upper and lower surface of bottom wall 13 to provide additional
support to the bucket adapter apparatus.
In the use of the adapter apparatus, assuming the conventional
bucket is mounted on the tractor, an operator slips the bifurcated
prongs onto the bottom wall 13 of the bucket until the plate member
15 abuttingly engages the lip or front edge of the bucket 10. Bolts
19 or other suitable connecting means are used to interconnect the
adapter apparatus with the bucket. The prongs 20 and 16, as an
example, may extend from 10 to 18 inches beyond the plate member 15
outwardly away therefrom.
A modification of the bucket adapter apparatus is to have the
prongs V- or L-shaped in cross section or an angle iron as shown in
FIG. 3 with the one wall portion 33 extending vertically upwardly
and normal to the other wall portion of the prong. Herein the long
prongs 30 and the short prongs 31 can be welded or otherwise
secured to the plate member 32 with the one vertically extending
wall 33 of the end prongs 30 lying in abutting contact with the
side wall 12 of the bucket 10 such that this combination cooperates
to penetrate cleanly into the mass of material being loaded,
cutting the straw which thereby facilitates the loading action. The
advantage of the long prongs 30, 31, 16 and 20 is that they can
triple the load worked over a conventional bucket if such bucket
were able to load the loose material thereon. The prongs 30 have
suitable bores 34 for registering with similar bores on the bottom
wall of a bucket and for receiving a bolt or stud to interconnect
the tractor bucket adapter to the bucket. A further modification is
shown in FIG. 4 wherein the longitudinally extending prongs 35 are
T-shaped in cross section and suitably connected to the plate
member 36. In addition to the plurality of elongated members 35, a
plurality of laterally spaced prongs 37 are similarly suitably
connected to the plate member 36. The elongated prongs 35 have
bores 38 suitably drilled into the rearward portion thereof to
provide means for interconnecting such adapter to the conventional
bucket as depicted in FIG. 1.
Various modifications are contemplated and may obviously be
resorted to by those skilled in the art without departing from the
described invention, as hereinafter defined by the appended
claims.
