1~)4~)909 MIRROR AND GUIDE DEVICE FOR A TRACTOR
SUMMARY OF THE INVENTION
This invention relates to a mirror and ~uide attach-ment device for a tractor having a trailing cultivator imple-; ment towed thereby.
When row crops are cultivated with a cultivatorimplement towed by a tractor, the tractor operator is required to constantly turn rearwardly during the cultivating operation to determine if the cultivating shovels and shields are prop-erly disposed with respect to the row crops being cultivated.on hillsides, the tractor tends to drift slightly in a lateral direction which sometimes results in the row crops being cov-.
ered with the soil. Therefore, unless the cultivator tools are properly aligned with respect to the crop rows, not only -~
will certain crop rows be covered with soil during the cultivat-ing operation, but in some instances, the cultivating shovels ;
will be spaced too far from the rows to effectively remove the weed~. It is also tiring for the tractor operator to con-stantly turn rearwardly from his normally forward facing posi-tion in order to view the cultivator tools during the cultivat--...... ~ .
ing operation.
It is therefore a general object of this invention to provide a mirror device which may be readily attached to a -tr~ctor having a cultivating implement connected thereto, to permit the tractor operator to readily and easily observe the . ~
row crops being cultivated while the operator faces in a gen-erally forward direction. It is also an o~ect of this invention to provide the mirror device with a guide assembly which per-mit~ the operator to accurately giide the tractor in a forward direction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
0~ THE INVENTION
Referring now to the drawings and more speciically to Figure 1, it will be ~een that one embodiment of the novel mirror and guide devlce, designated generally by the reference ~:
nuJeral 10, is shown ~ounted in cooperative relat$on on a con- :-30 ventional tractor 11 to which is connected a trailing cultivator ~ -i~plement 12. The tractor 11 is provided with ground engaging -;
.' :
-2-1~4~5~Q9 wheels including a pair of front wheels 13. The cultivator im-plement 12 is of conventional construction and includes a frame including a tool bar which has a plurality of cultivator shovels 14 and rolling shields 15 secured thereto. The cultivator shovels 14 are adapted to c~ultivate the soil between the rows of a conventional row crop such as beans, corn or the like, while the rolling shields 15 are arranged in pairs and the shields of eAch pair are disposed on opposite sides of a crop row to pre-vent the crop row from being covered during the cultivating operation.
The mirror and guide device 10 includes means for mounting the device on the tractor 11 and this means includes an elongate substantially straight channel bracket 16 including a web 17 having flanges 18 secured thereto and projecting there-from. The web of the channel bracket 16 i8 provided with open-ings detachably mount the channel bracket on the body of the tractor.
The channel bracket 16 provides a mounting for a mirror assembly 20 which is comprised of a generally rectangular frame 21, including elongate straight side frame element~ 22 rigidly secured to transverse frame elements 23. It will be noted that these frame elements are of angle construction.
Referring now to Figures 4 and 5, it will be seen that a pair of elongate substantially straight angle brackets - ~ -24 are each rigidly secured to the front s~rface of one of the --side frame elements 22 and project forwardly therefrom. In this respect, one flange of each angle bracket 24 is spaced forwardly from the associated side frame elements 22. A substantially $1at, ~ ~-generally rectangular shaped rear plate 25 is dispo~ed between 30 the angle brackets 24 and the frame elements of the rectangular -frame 21, the rear plate being rigidly secured to the angle bracket~ 24.
16~4'~ 9 A generally rectangular shaped flat mirror 26 is mounted on the rectangular frame 21 by a pair of vertical dam-pening elements 27 and a pair of transverse dampening elements 28. These dampening elements are formed of a yieldable resilient material preferably rubber and each has an elongate inner slot 29 therein and an elongate outer slot 30 therein. It will be ~een that the inner slot 29 of each dampening elements receives a mar-ginal portion of the mirror therein while the outer slot of each dampening element receives a flange of an adjacent frame element thereon.
, ...... ...
The mirror assembly also includes a shield structure 31 which is comprised of a pair of substantially identical triangular side shield plates 32, each including an upper an-gular edge, 33, a lower angular edge 34 and a vertical edge 35.
The shield structure is also comprised of a top shield plate 36 ~,;
which is of generally rectangular configuration, as best seen in Figure 5, and which has a curled or rolled upper edge 37. The side edges 38 of the top plate are rigidly secured to the upper an-gular edges 33 of the side shield plates 32 and the rear edge portion 39 is r~gidly secured to the uppermost trans~erse frame element 23 and projects forwardly therefrom. It will also be noted that the lower angular edges 34 of the side shield plates are rigidly secured to the side frame elements 22 of the rectangular frame 21. The shield structure 31 iot only protects the mirror from flying objects such as stones or the like, but the shield structure also ~erves to minimize glare with respect to the -;
reflective surface of the mirror. In this respect, the inner ~urfaces of the top and side plates of the shield structure may be painted with a flat or non-reflective material to further minimize glare.
~ he mirror asse~bly 20 is connected to the channel bracket 16 by means of an elongate upper brace 40 and a pair of , " ' , , ", " 1". , ~,.", ', . . ;',, 1~4C19~J9 elongate lower braces 41. Referring now to Figure 5, it will be noted that the respective forward ends of the braces are rigidly secured to the lower flange of the channel bracket 16 and the braces project outwardly and rearwardly therefrom. The rear-ward end of the upper brace 40 is connected to the upper end por-tion of the outermost side frame element 22. The rearward ends of the lower braces 41 are each connected to the lower end portion of one of the side frame elements 22. It will be noted as best seen in Figures 2 and 3 that when the channel bracket 16 is mounted on the tractor, the rectangular frame and a mirror 26 will be s disposed in angulated relation and will extend downwardly and rearwardly to facilitate observation of the cultivator tools by the tractor operator.
Means are also provided for protecting the mirror against damage when the tractor is being driven from one location to another and it is not being used in a cultivating operation.
To this end, a substantially flat, generally rectangular shaped cover plate 42 is provided, having a rolled inner edge 43 through which projects a pivotal or hinged pin 44. The hinge pin is connec- ~
20 ted to the frame 21, adjacent the inner side thereof to swingably ~:
mount the cover plate thereon for swinging movement between open ~nd closed positions. When the cover plate 42 is in the closed position, the cover plate covers the rear surface of ~he mirror and will prevent damage thereto. However, when the cover p~ate . -~
42 i8 in the open position, it will be positioned adjacent the innermost side plate of the shield structure, and will in no way . ;.
ob~truct the vi~ion of the tractor operator with respect to the : :;
mirror. ~ -It will be noted that because of the angulated re- :-.
lation of the mirror and supporting frame 21,.the cover plate 42 will normally be. ur~ed to the clo~ed position by the action ~ ~ -of gravity. Means are therefore provided for retaining the cover 104~)9~)9 plate in an open condition. This means includes an elongate flexible member of rope 46 which has one end thereof extending through an opening 45 in the cover plate and has its other end extending upwardly to,a point adjacent the tractor operator.
With this arrangement, the tractor operator may retain the uover plate in an open position and by merely releasing the taut ' ' rope, the cover plate may be allowed to swing to the closed position.
Means are also provided for facilitating guiding of the tractor during the cultivating operation and this means includes a guide assembly~47. The guide assembly 47 is comprised of a mounting sleeve 48 which is regidly secured to the channel bracket 16 and which is provided with a set screw 49. An L-shaped mounting arm 50 includes an elongate vertical portion 51, a horizontal portion 52 and a terminal portion 53 which projects angularly from the vertical portion 51. The terminal portion 53 projects into the mounting sleeve 48 and is secured in a pre- - :
selected angulated relation by the set screw 49. The horizontal , portion 52 of the L-shaped mounting arm 50 has a mounting sleeve ' ', 20 54 mounted thereon and provided with a set screw 55. Thus the l-, mounting sleeve 54 may be adjusted longitudinally as well as ,~
angularly with respect to the horizontal portion 52~ The mounting sleeve 54 also has a stud 66 rigidly affixed thereto and projecting outwardly therefrom.
The guide assembly includes an elongate substantially ,, straight guide rod or element 57 which is provided with a sleeve 58 rigidly affixed thereto, adjacent one end thereof. The sleeve '' 58 is also provided with a set screw 49 and is mounted on the '~
stud 56. With this arrangement, the sleeve may be rotated on the ';
~tud 56 to adjust the angular position of the guide rod 57.
It will al~o ba noted that the guide ascembly is capable of a wide range of ad~ustnent to properly position the guide rod in ~04~)909 a predetermined position to facilitate guiding of the tractor during the cultivating o~eration. In this respect, the guide rod will be positioned so that the sight line of the tractor operator centers the guide rod with respect to a crop row to be cultivated.
This permits the tractor to be properly guided between the rows during the cultivating operation.
During the cultivating operation, the tractor will be driven in a forward direction so that the cultivator shovels of the cultivator implement will cultivate the soil between the rows. The 5hields of a pair of rolling shields will be dis-posed on opposite sides of the rcw being cultivated. The mirror assembly 20 permits the operator to clearly view at least one pair of the rolling shield assembliessas~well~as the adjacent cultivator shovels located on opposite sides thereof.
Thus the tractor operator, by properly positioning the pair of rol-ling shields being observed and adjacent pair of cultivator shovels with respect to a single row will be assurea that effec-tive cultivation is accomplished without danger of covering the -plants with soil or damage of plant roots by the cultivator shovels. Since the mirror assembly is positioned just rearwardly of and at approximately the same level as the right front wheel of the tractor, the op~rator may face forwardly at all times, but will have an excellent, unobstructed view of a pair of rolling shields and cultivator shovels during the cultivating -ope~ation.
By mounting the guide assemblies adjacent but just forwardly of the mirror assembly, the mirror and the guide as-sembly are in an optimum position for observation by the tractor operator. Thus the forward travel of the tractor as well as the precise positioning of the cultivator shields and cultivator shovels are ¢onstantly in the vision of the tractor operator while permitting the operator to comfortably face forwardly 16~4~9~9 at all times.
Thus it will be seen that I have provided a novel mirror and guide device which may be readily mounted on any conventional tractor and which allows the tractor operator to effectively cultivate while facing forwardly at all times.
It will further be noted that I have provided a novel mirror guide device which is not only of simple and inexpen-sive construction, but one which functions in a more effic~ont manner than any ~retofore known comparable device.
_~_
The mirror and guide device 10 includes means for mounting the device on the tractor 11 and this means includes an elongate substantially straight channel bracket 16 including a web 17 having flanges 18 secured thereto and projecting there-from. The web of the channel bracket 16 i8 provided with open-ings detachably mount the channel bracket on the body of the tractor.
The channel bracket 16 provides a mounting for a mirror assembly 20 which is comprised of a generally rectangular frame 21, including elongate straight side frame element~ 22 rigidly secured to transverse frame elements 23. It will be noted that these frame elements are of angle construction.
Referring now to Figures 4 and 5, it will be seen that a pair of elongate substantially straight angle brackets - ~ -24 are each rigidly secured to the front s~rface of one of the --side frame elements 22 and project forwardly therefrom. In this respect, one flange of each angle bracket 24 is spaced forwardly from the associated side frame elements 22. A substantially $1at, ~ ~-generally rectangular shaped rear plate 25 is dispo~ed between 30 the angle brackets 24 and the frame elements of the rectangular -frame 21, the rear plate being rigidly secured to the angle bracket~ 24.
16~4'~ 9 A generally rectangular shaped flat mirror 26 is mounted on the rectangular frame 21 by a pair of vertical dam-pening elements 27 and a pair of transverse dampening elements 28. These dampening elements are formed of a yieldable resilient material preferably rubber and each has an elongate inner slot 29 therein and an elongate outer slot 30 therein. It will be ~een that the inner slot 29 of each dampening elements receives a mar-ginal portion of the mirror therein while the outer slot of each dampening element receives a flange of an adjacent frame element thereon.
, ...... ...
The mirror assembly also includes a shield structure 31 which is comprised of a pair of substantially identical triangular side shield plates 32, each including an upper an-gular edge, 33, a lower angular edge 34 and a vertical edge 35.
The shield structure is also comprised of a top shield plate 36 ~,;
which is of generally rectangular configuration, as best seen in Figure 5, and which has a curled or rolled upper edge 37. The side edges 38 of the top plate are rigidly secured to the upper an-gular edges 33 of the side shield plates 32 and the rear edge portion 39 is r~gidly secured to the uppermost trans~erse frame element 23 and projects forwardly therefrom. It will also be noted that the lower angular edges 34 of the side shield plates are rigidly secured to the side frame elements 22 of the rectangular frame 21. The shield structure 31 iot only protects the mirror from flying objects such as stones or the like, but the shield structure also ~erves to minimize glare with respect to the -;
reflective surface of the mirror. In this respect, the inner ~urfaces of the top and side plates of the shield structure may be painted with a flat or non-reflective material to further minimize glare.
~ he mirror asse~bly 20 is connected to the channel bracket 16 by means of an elongate upper brace 40 and a pair of , " ' , , ", " 1". , ~,.", ', . . ;',, 1~4C19~J9 elongate lower braces 41. Referring now to Figure 5, it will be noted that the respective forward ends of the braces are rigidly secured to the lower flange of the channel bracket 16 and the braces project outwardly and rearwardly therefrom. The rear-ward end of the upper brace 40 is connected to the upper end por-tion of the outermost side frame element 22. The rearward ends of the lower braces 41 are each connected to the lower end portion of one of the side frame elements 22. It will be noted as best seen in Figures 2 and 3 that when the channel bracket 16 is mounted on the tractor, the rectangular frame and a mirror 26 will be s disposed in angulated relation and will extend downwardly and rearwardly to facilitate observation of the cultivator tools by the tractor operator.
Means are also provided for protecting the mirror against damage when the tractor is being driven from one location to another and it is not being used in a cultivating operation.
To this end, a substantially flat, generally rectangular shaped cover plate 42 is provided, having a rolled inner edge 43 through which projects a pivotal or hinged pin 44. The hinge pin is connec- ~
20 ted to the frame 21, adjacent the inner side thereof to swingably ~:
mount the cover plate thereon for swinging movement between open ~nd closed positions. When the cover plate 42 is in the closed position, the cover plate covers the rear surface of ~he mirror and will prevent damage thereto. However, when the cover p~ate . -~
42 i8 in the open position, it will be positioned adjacent the innermost side plate of the shield structure, and will in no way . ;.
ob~truct the vi~ion of the tractor operator with respect to the : :;
mirror. ~ -It will be noted that because of the angulated re- :-.
lation of the mirror and supporting frame 21,.the cover plate 42 will normally be. ur~ed to the clo~ed position by the action ~ ~ -of gravity. Means are therefore provided for retaining the cover 104~)9~)9 plate in an open condition. This means includes an elongate flexible member of rope 46 which has one end thereof extending through an opening 45 in the cover plate and has its other end extending upwardly to,a point adjacent the tractor operator.
With this arrangement, the tractor operator may retain the uover plate in an open position and by merely releasing the taut ' ' rope, the cover plate may be allowed to swing to the closed position.
Means are also provided for facilitating guiding of the tractor during the cultivating operation and this means includes a guide assembly~47. The guide assembly 47 is comprised of a mounting sleeve 48 which is regidly secured to the channel bracket 16 and which is provided with a set screw 49. An L-shaped mounting arm 50 includes an elongate vertical portion 51, a horizontal portion 52 and a terminal portion 53 which projects angularly from the vertical portion 51. The terminal portion 53 projects into the mounting sleeve 48 and is secured in a pre- - :
selected angulated relation by the set screw 49. The horizontal , portion 52 of the L-shaped mounting arm 50 has a mounting sleeve ' ', 20 54 mounted thereon and provided with a set screw 55. Thus the l-, mounting sleeve 54 may be adjusted longitudinally as well as ,~
angularly with respect to the horizontal portion 52~ The mounting sleeve 54 also has a stud 66 rigidly affixed thereto and projecting outwardly therefrom.
The guide assembly includes an elongate substantially ,, straight guide rod or element 57 which is provided with a sleeve 58 rigidly affixed thereto, adjacent one end thereof. The sleeve '' 58 is also provided with a set screw 49 and is mounted on the '~
stud 56. With this arrangement, the sleeve may be rotated on the ';
~tud 56 to adjust the angular position of the guide rod 57.
It will al~o ba noted that the guide ascembly is capable of a wide range of ad~ustnent to properly position the guide rod in ~04~)909 a predetermined position to facilitate guiding of the tractor during the cultivating o~eration. In this respect, the guide rod will be positioned so that the sight line of the tractor operator centers the guide rod with respect to a crop row to be cultivated.
This permits the tractor to be properly guided between the rows during the cultivating operation.
During the cultivating operation, the tractor will be driven in a forward direction so that the cultivator shovels of the cultivator implement will cultivate the soil between the rows. The 5hields of a pair of rolling shields will be dis-posed on opposite sides of the rcw being cultivated. The mirror assembly 20 permits the operator to clearly view at least one pair of the rolling shield assembliessas~well~as the adjacent cultivator shovels located on opposite sides thereof.
Thus the tractor operator, by properly positioning the pair of rol-ling shields being observed and adjacent pair of cultivator shovels with respect to a single row will be assurea that effec-tive cultivation is accomplished without danger of covering the -plants with soil or damage of plant roots by the cultivator shovels. Since the mirror assembly is positioned just rearwardly of and at approximately the same level as the right front wheel of the tractor, the op~rator may face forwardly at all times, but will have an excellent, unobstructed view of a pair of rolling shields and cultivator shovels during the cultivating -ope~ation.
By mounting the guide assemblies adjacent but just forwardly of the mirror assembly, the mirror and the guide as-sembly are in an optimum position for observation by the tractor operator. Thus the forward travel of the tractor as well as the precise positioning of the cultivator shields and cultivator shovels are ¢onstantly in the vision of the tractor operator while permitting the operator to comfortably face forwardly 16~4~9~9 at all times.
Thus it will be seen that I have provided a novel mirror and guide device which may be readily mounted on any conventional tractor and which allows the tractor operator to effectively cultivate while facing forwardly at all times.
It will further be noted that I have provided a novel mirror guide device which is not only of simple and inexpen-sive construction, but one which functions in a more effic~ont manner than any ~retofore known comparable device.
