AN IMPROVED COUPLER COVER
This invention relates to an improved coupler cover for preventing contaminants from contacting the outer end sur~ace of a coupler. In particular, the improved coupler cover will prevent foreign contaminants from contacting the end surEace of a female coupler located on the rear of agricultural vehicles.
Description of the Prior Art Currently, most agricultural and some industrial tractors are equipped with one or more pairs of hydraulic hookups, such as female couplers, which are attached to the rear of the vehicle.
These hydraulic couplers are designed to provide attachment means which mate with male couplers attached to an implement's hydraulic hoses. During the process of changing implements, the hydraulic hoses have to be disconnected and connected by the operator. In the process of disconnecting the male coupler from the female coupler, a small amount of oil tends to be trapped between the two ends of the couplers. This oil adheres to the end surface of the female coupler and provides an adhesive means on which dust, dirt or other foreign matter can accumulate. When the operator hooks on another implement, the foreiyn contaminant is forced into the hydraulic lines ancl causes havoc with the associated hydraulic apparatus.
In the past, manufacturers have tried to prevent such contamina-tion by ins-talling covers or boots over the end surface oE the Eemale couplers. Some oE -these boots contained a s:inyle slit through which the male coupler was inserted so as to connec-t to the female coupler. These single s:lit boot~ were partiall~v eEEective in prevent:~ny the in~lux of foreiyn matter into the hoses in the coupled pOSitiOIl rrhe rea~on for thi~ was that the qinyle sl:Lt dicl not have the ability to seal up agains-t the entire circumEerence o:E the male coupler. The opening there-between thus allowed dust or dirt to again come in contact with . '~
/3~
1 -the end surface of the female coupler. A second disadvantage oE
the single slit boots was -that the boots tended to fracture and tear at the ends of the slits after repeated use. r~his physical failure rendered the boots ineffective and necessitated replace-ment.
Other prior art covers have -tried to overcome the physical failure problem by using more than one slit or by using various types of soft, pliable material. Although the cracking problem was less severe t the major contamination problem still remained.
Now an improved coupler cover has been invented which rectifies the deficiencies of the prior art coupler covers~
The general object of this invention is to provide an improved coupler cover which will prevent foreign contaminants from contacting the end surface of a coupler. A more specific object of this invention is to provide an improved coupler cover which will protect the end surface of a female coupler. -Another object of this invention is to provide an improved coupler cover which will not tear or fracture as easily as conventional covers.
Still another object oE this invention is to provide a low cost, easy-to-manufacture coupler cover.

The multiple slits of the first diaphragm are offset in position from -the multiple slits of the second diaphragm.

Detailecl Deseripti,on o~ _he ~nvention Re,Lerriny now -to Flg. 1, -the rear of an agriultural -traetor 10 :is clep,ict.ed havincJ two pairs o e hydxaulic hookups 11 and 12.
Each pair o~ hookups 11 and 12 con-tains means Eor a-ttaehing two hydraulic lines or hoses to it. One oE the llnes will earry oil -to an attached farm implement and the other line will return the 1 oil to a reservoir contained within the body of the tractor 10.
Commonly, the hydraulic hookups 11 and 12 are female couplers which are designed to mate with suitable male couplers attached to one end of the hydraulic hoses. In the process of connecting and disconnecting the hydraulic couplers, a certain quantity of oil tends to become trapped between the female or male couplers.
Such oil ends up adhered to the rear of the tractor 10, whereby it provides a bond for holding dust, dirt or other foreign contam-inants to the tractor 10.
The improved coupler cover 14 (shown in Fig. 2) is designed to prevent these foreign contaminants from infiltrating into the hydraulic lines. The coupler cover 14 includes two diaphragms 16 and 18, respectively, axially aligned adjacent to each other.
Each of the diaphragms 16 and 18 is constru~ted of a flexible, deformable, soft elastomeric material, such as rubber, which is capable of being repeatedly deformed without cracking. Each of the diaphragms 16 and 18, which may be of any desired shape, contain a multiplicity of slits 20 (see Fig. 3~ arranged so as to extend outward from the center 22 of each of -the diaphragms 16 and 18. By multiplicity is meant three or more slits wi,th six slits being a preferred number (see Fig. 7~. Each of -the slits 20 is preferably of equal length and should be arranged so as to be spaced an equal distance apart. In Fig. 3, the three slits in , the ou-ter diaphragm 16 are arranged 120 degrees apart and extend , outward to approximately the perimeter ~ small round hole 26 '~ can be cons-kructed a-t -the outer encl of eaah sl:Lt -to aid in pre-ven-ting tear:Lng of -the elas-tic material. Such cons-truction is, however, a mat-ter of prefererlce and does not eEfect the functional operatl,on Oe the coupler cover 1~.
The second or inner diaphragm 18 is construc-tecl exaatly like the first diaphragm 16 but i5 positioned in such a manner that its sli-ts 20 will be angularly offset in position from the slits ~3~5g3~6 1 20 of the first diaphragm 16. Preferably, the slits 20 of the second diaphragm 18 will lie midway between two neighboring slits 20 on the first diaphragm 16. As shown in the arrangement in Fig. 3, the three slits of the second diaphragm 18 (shown in dotted lines) are 60 degrees offset fro~n the three slits 20 of the first diapl~ragm 16. Other offset angles are feasible provided that the slits of the two diaphragms 16 and 18 are not arranged too close together.
Referring again to Fig. 2, the first and second diaphragms 16 and 18, respectively, are secured to a retainer 30 having a port hole 32. The retainer 30 is fastened to the housing of a vehicle so as to extend around a hydraulic hookup, such as shown in Fig. 1. The port hole 32 permits any trapped oil retained between the end surface of the female coupler and the surface of the second diaphragm 18 to be bled off.
Referring no~ to Fig. 4, an alternative embodiment of the improved coupler cover 14 is shown. This embodiment also employs a first and second diaphragm 34 and 36, respectively, which are designed to be inserted directly into a hydraulic housing 38.
~he housing 38 contains the female coupler 40 positioned a desired distance in from the second diaphram 36.
~ s better seen in Fig. 6, each of diaphragms 34 and 36 (of which only diaphragm 34 is shown) is constructed from a flexible, deformable, soft elastomeric material having a multiplicity of sLits 42. Construc~ed between two neighboring s:Lits on one surface oE each diaphragm 34 and 36 is a suppor-t:ing rib 44. The ribs 44 are pre~erably cons-tructed of the same elastomeric material as are -the diaphragms 34 ancl 36~ It i5 preferable to make the ri.bs 44 part Oe each of the cliaphragms 3~ and 36 such as by molding the elements together into a single member. rrhe purpose of each rib 44 is to assist in deflecting each pie-shaped surface 46 of each of -the diaphragms 34 and 36 back to its original
~ ~ ,r~ 3~t;
1 slits are arranged in a spaced apart configuration and extend in an outward directon Erom the center o~ each diaphragm. The multiple slits of the first diaphragm are offset in position from -the multiple slits of the second diaphragm. Secured to both diaphragms is a retainer which holds both of the diaphragms relative to the end surface of the coupler.
The combination of the two flexible diaphragms together with the offset slits provides a much improved seal for preventing the influx of foreign matter. The multiple slits also allow for a smaller degree of deflection of each diaphragm and therefore they tend to prolong the useful life of the coupler cover.

Each pair o~ hookups 11 and 12 con-tains means Eor a-ttaehing two hydraulic lines or hoses to it. One oE the llnes will earry oil -to an attached farm implement and the other line will return the 1 oil to a reservoir contained within the body of the tractor 10.

Such oil ends up adhered to the rear of the tractor 10, whereby it provides a bond for holding dust, dirt or other foreign contam-inants to the tractor 10.
The improved coupler cover 14 (shown in Fig. 2) is designed to prevent these foreign contaminants from infiltrating into the hydraulic lines. The coupler cover 14 includes two diaphragms 16 and 18, respectively, axially aligned adjacent to each other.
Each of the diaphragms 16 and 18 is constru~ted of a flexible, deformable, soft elastomeric material, such as rubber, which is capable of being repeatedly deformed without cracking. Each of the diaphragms 16 and 18, which may be of any desired shape, contain a multiplicity of slits 20 (see Fig. 3~ arranged so as to extend outward from the center 22 of each of -the diaphragms 16 and 18. By multiplicity is meant three or more slits wi,th six slits being a preferred number (see Fig. 7~. Each of -the slits 20 is preferably of equal length and should be arranged so as to be spaced an equal distance apart. In Fig. 3, the three slits in , the ou-ter diaphragm 16 are arranged 120 degrees apart and extend , outward to approximately the perimeter ~ small round hole 26 '~ can be cons-kructed a-t -the outer encl of eaah sl:Lt -to aid in pre-ven-ting tear:Lng of -the elas-tic material. Such cons-truction is, however, a mat-ter of prefererlce and does not eEfect the functional operatl,on Oe the coupler cover 1~.
The second or inner diaphragm 18 is construc-tecl exaatly like the first diaphragm 16 but i5 positioned in such a manner that its sli-ts 20 will be angularly offset in position from the slits ~3~5g3~6 1 20 of the first diaphragm 16. Preferably, the slits 20 of the second diaphragm 18 will lie midway between two neighboring slits 20 on the first diaphragm 16. As shown in the arrangement in Fig. 3, the three slits of the second diaphragm 18 (shown in dotted lines) are 60 degrees offset fro~n the three slits 20 of the first diapl~ragm 16. Other offset angles are feasible provided that the slits of the two diaphragms 16 and 18 are not arranged too close together.
Referring again to Fig. 2, the first and second diaphragms 16 and 18, respectively, are secured to a retainer 30 having a port hole 32. The retainer 30 is fastened to the housing of a vehicle so as to extend around a hydraulic hookup, such as shown in Fig. 1. The port hole 32 permits any trapped oil retained between the end surface of the female coupler and the surface of the second diaphragm 18 to be bled off.
Referring no~ to Fig. 4, an alternative embodiment of the improved coupler cover 14 is shown. This embodiment also employs a first and second diaphragm 34 and 36, respectively, which are designed to be inserted directly into a hydraulic housing 38.
~he housing 38 contains the female coupler 40 positioned a desired distance in from the second diaphram 36.
~ s better seen in Fig. 6, each of diaphragms 34 and 36 (of which only diaphragm 34 is shown) is constructed from a flexible, deformable, soft elastomeric material having a multiplicity of sLits 42. Construc~ed between two neighboring s:Lits on one surface oE each diaphragm 34 and 36 is a suppor-t:ing rib 44.

1 posit.ion after the male coupler has been removed. The shape of each of the ribs 4~ is not critical, but a shape similar to that shown in Fig. 5 wherein the rib 44 narrows in width as it ap-proaches the center 48 of the diaphragm is advantageous. This configuration provides the extra strength at the periphery 5~ of the diaphragm where it is needed.
The shape of the outer surface ~2 of the diaphrac~m 34 or 36 can be either flat, concave or convex. The concave shape of outer surface 52 is preferred in that it provides less resistance when the operator inserts the male coupler. This concave shape also decreases the amount of travel needed to return the outer surface 52 to its original shape. This feature aids in prolonging the life of the improved coupler cover 14.
Surrounding the periphery 50 of the diaphragm 34 or 36 is a metal rim 54. The metal rim 54 is bonded or otherwise attached to the periphery 50 and is designed to be inserted into a re-ceptacle such as the housing 38, as shown in Fig. 4. ri'he width of the metal rim 54 can be varied so as to adjust the distance between the first diaphragm 34 and the second diaphragm 36. This allows each manufacturer to apply the coupler cover 1~ to his particular housing 38 without encountering hookup problems.
