DUAL MATERIAL DISPENSING ASSEMBLY
This invention relates to a seeding apparatus and in particular to a sub assembly of a seeding apparatus for expeditiously and separately depositing seed and fer-tilizer ~i in the ground at a most precise and advantageous location. `-~
. . .::
This application is related to copending Canadian Patent application 2,069,081 classified in AOlC - 007/06 in the Canadian Patent Office and filed by the same Inventor, Norbert F. Beaujot. This application for a "dual material .~ dispensing assembly" is an improvement on the "seed row assembly" claimed in the previous application and can be substltuted therefor.
As previously pointed out there is an increasing awareness of the need to conserve the dry land soil resource existing in many parts of the country. Cultivators have in many cases ' been adapted to serve as a seeding machine but there has been a lack of depth control and sufficient packing of soil around ;~ the seed. With the advent of minimum or zero tillage for seed bed preparation to minimize the cost of production new implements such as applicants apparatus have been devised.
Problems to overcome were the heavy previous crop résidue and difficult precise penetration of the unworked soil.
Several attempts have been made to overcome the problems of ~proper seed and fer-tilizer deposition under the above adverse conditions. The most closely related attempts known to applicant are described in Canadian Patent 1,239,835 to Halford and United States Patents 3,362,361 to Morrison and 2,981,213 to O'Neil.
~3 In patent "835" there is disclosed a first dispensing means j ~ .
. ., :
2~3~2~
rigidly fixed to an implement frame, a second dispensing means pivotally mounted relative to the frame and an adjustment or biasing means connected between the frame and the second pivotal dispensing means mounting. In contrast applicants device has a first dispensing means pivotally mounted on an elongate body member and a second dispensing ~.,l means fixed to the elongate body member with an adjustable gauge packer wheel fixed to the second dispensing means.
~3 In patent "351l'there is disclosed a first dispensing means fixed to a first tool bar of the frame with a trip release mechanism provided on the shank of the tool. The second ;~ dispensing means includes a floating assembly fixed to a second tool bar with a trench forming wheel in front and a press wheel in the rear with the seed tube vertically - ;
moveable relative to its mounting tool bar. In contrast applicants device has a first dispensing means which is pivotally mounted on an elongate body member which is ~'', pivotally mounted on the frame. A second dispensing means is fixed to the elongate body member and has fixed thereto 20 an adjustable gauge press wheel. ~3 ' " ~
In patent "213" there is disclosed a first dispensing means having a furrow opener disc where depth is con-trolled by a gauge wheel both being mounted on the same pivotal arm. A
second dispensing means is taught that has a pivoting furrow ~: opener with attached seed tube. In contrast applicants first i~ dispensing means has a knife furrow opener pivotally at-tached :~ to an arm or elongate body member that is pivotally attached to the frame. The second dispensing means also has a ~nife furrow opener and is rigidly fixed to the same arm or elonyate body member as the first dispensing means.

~ ,, .. ~ .
~ccording to the present invention there is provided a dualmaterial dispensiny assembly comprising, an elongate body member to be pivotally attached to the frame of a seeding apparatus, a first dispensing means pivotally mounted on the elongate body member, a second dispensing means fixedly mounted on the elongate body member and a gauge packer means adjustably mounted on the elongate body member. A controlled ~ biasing means is pivotally connected between the first ,~i dispensing means and the frame... ~' .
,~ 10 From the above summary it is readily discernible that the " primary object of the instant invention is to provide a dual material dispensing assembly that will deposit two separate materials in the soil or ground in a precise and expeditious }:~ manner.
-~'~ ' , .
It is a further object of this invention to provide seed and -~
fertilizer dispensing means with a high trash clearance.
It is a further object of this invention to provide a ~;
dispensing assembly that does not require vertical movement of the frame for satisfactory operation.
'`~1 .
20 It is yet another object of this invention to provide dual material dispensing that will cause a minimum of soil ~¦ disturbance.
,. 1 , ~' These and other objects of the present invention will become readily apparent as the following detailed description is read in conjunction with the accompanying drawings wherein -like reference numerals will indicate like elements ' throughout the several views.

!~. ~ ~ :
Reference is now made to figure l where there is shown the 10 dual material dispensing assembly as it would appear in ,~
, ,~
operation. The assembly is shown mounted on a standard or typical box main frame 34 of a planting apparatus by "~ " ;~
bolts 33. The "~ " bolts 33 fasten a main frame mounting bracket 31 to the typical box type main frame 34. Pivotally connected at 32 to the main frame mounting bracket 31 is an elongate body member 36. The elongate body member is laterally ;~
supported by an elongate body member mount 37 on one side and an elongate body member brace 35 on an opposite side.
Intermediate the ends of elongate body member 36 is a pivot mount 26 to pivotally mount pivot bracket 21 there-to.
Releasable biasing means are generally but not necessarily in the form of a double acting hydraulic cylinder 27 and are pivotally connected at a first end by a cylinder pivot pin 25 ;
to pivot bracket 21 and at a second end to main frame mounting bracket 31 by a cylinder pivot pin 30. The double acting hydraulic cylinder 27 has two fluid conductors 28 and 29.
Pressure in the fluid conductor 28 supplies trip and packing pressure while pressure in conductor 29 supplies a force to lift the dual material dispensing assembly out of the ground for turning or transport. The hydraulic controls 44 are those illustrated in figure 7 of Canadian application 2,069,081 as ;~

referred to above and do not form a part of this inven-tion.
The pivot bracket 21 carries a first dispensing means knife 18-which is generally bolted to the pivot bracket 21 and with extra apertures is vertically adjustable for changing seed to fertilizer depth proximity. On the forward tip of the knife 18 is found a carbide wear -tip 17. On the rearward edge of the knife 18 is mounted a fertilizer dispensing tube 19 which receives fer-tilizer from a supply via a conduit or hose 22.
,',~ ,' ' .
The operational movement of the seeding apparatus is such that the first or fertilizer dispensing means is first to engage the soil or ground and therefore with its knife 18 cuts a furrow for the deposition of fertilizer. The knife 18 with it wear tip 17 is also first to engage any obstacles as the "f,~ :
apparatus moves forward. When an obstacle is encountered by the knife 18 it generates an overload pressure in the '~ cylinder 27 which is transferred to the hydraulic control 44 which releases the pressure allowing the knife 18 to trip or release and pass over the obstacle. The kni~e 18 and the remainder of the first dispensing means then is brough-t ;i~ forward by the hydraulic cylinder 27 to its normal operating position by a restoration pressure from the hydraulic controls 44. The forward movement of the first dispensing means is limited by a flexible tensile member or tether 16 which is normally in the form of a chain. The hydraulic ~-~
cylinder 27 with hydraulic controls 44 is therefore considered to be a releasable biasing means. `-The elongate body member 36 has welded or otherwise rigidly ;;
attached thereto a second dispensing means to place seed in the soil. The dispensing means has a seed knife mount 14 -. ~ .
2~392~
~;. welded to the elongate body member 36. Mounted on the seed '!
knife mount 14 is a seed knife bolt plate 13 attached thereto by mounting bolts 15. Connected to the seed knife bolt plate 13 is seed tube 12 which carries at its forward edge a seed knife 11 with carbide wear tip 10. Seed from~a supply passes through a conduit or feed line 38 into a seed and air deceleration and air removal chamber 23. This chamber 23 has on its upper surface apertures 24 for the exhausting of a . ~ ;
portion of the air conveying the seed to prevent any damage ~ ;
thereto. The seed tube 12 receives seed from the deceleration chamber 23 to place it into a furrow in the ground made by ~ :
the seed knife 11. On the rear of the seed knife mount 14 is a depth adjustment gauge 9 to indicate the vertical movement of the adjustable packer means. From the seed or ;~
second dispensing means a flexible tensile member or tether 16 normally in the form of a chain extends from a seed knife mount bolt 15 to the first dispensing means knife 18 to limit its movement away from the second dispensing means when it is . .
moved by the hydraulic releasable biasing means 27. Movement of the first dispensing means knife 18 in a rearward direction is firstly limited by limit stop 43. Further rearward movement raises the complete assembly out of the ground as it pivots : : .:
about pivot 32.

A depth adjustmen-t jack outer member 7 is welded or otherwise fixed to the rear of seed knife mount 14 and to elonyate body member 36. A depth adjustment jack inner member 4 is telescopically moved within the jack outer member 7 by . rotatiny a depth adjustment jack screw 5 which reacts wit~ a depth adjustment jack nut 6 welded to jack inner member ~.
The rotation of jack screw 5 is accomplished by rotation ~'~ji,depth adjustment jack handle 8.

packer wheel there is indicated a-t 40 the packed ground level, at 41 the seed location, and at 42 the fertilizer location.

~ Referring now to fiyure 2 which is a plan view of figure 1 .,i, ~ , .
there is shown the exact same dispensing assembly but which `.~ more clearly shows the dimensions of the main frame bracket 31 and how two "~ " bolts 33 clamps the main frame bracket 31 to i~ 10 the main frame 34. The elongate body member mount 37 hidden i5;i','~ in figure 1 is now clearly shown. The elongate body member ,,;
brace 35 is now illustrated to give it its proper dimension.
The seed and air deceleration and air removal chamber 23 is generally made of plastic and receives the seed tube 12. The pattern of the apertures 24 is now illustrated more clearly.
~ All the remaining elements with their location and function .:,;.
should be quite obvious to one skilled in the art. ;
j! , i~1 To more clearly illustrate the lower por-tion of the second or seed dispensing means there is shown in figure 3 a seed ~,; 20 knife bolt plate 13 having fixed thereto a seed tube 12. To the front of the seed tube 12 is fixed a seed knife 11 which i~ prepares a furrow in the ground for the seed as well as strengthen the seed tube, which is rearwardly inclined to more easily pass over obstacles in its path. A carbide wear tip 10 has also been provided to decrease the wear and tear on `~
the knife.
~ " '''~
Now referring to figure 4 there is shown the seed knife mount 14 which is generally welded to the elongate body `~ member 36. The seed knife bolt plate 13 is shown spacedly ~ -30 fixed by mount bolts 15 -to seed knife mount 14 but may be -~ ' ~
;'~ .' :.,:

~, As previously pointed ou-t this is a transverse cross section ~ -~
at one of the seed knife mount bolts 15. The rear of seed ~;
tube 12 abuts the seed knife mount 14 and is fixed to the ~
~ . ~
seed knife bolt plate 13. The seed knife llis shown fixed to the front of seed tube 12 and carries a carbide wear tip 10 at a lowermost portion thereof. On the rear of the seed knife mount 14 is mounted a scale or depth gauge to cooperate with a pointer or indicator on the wheel fork 3 to ~, 10 give the operator of the machine an indication of the depth ~
of placement of the material being dispensed. ~-Various modifications such as size, shape and arrangement of components may be made without departing from the spirit and scope of the invention.
