Abstract
ABSTRACT
An auxiliary equipment attachment adapter, to be used in pairs, semipermanently attaches to the customary mounting fixtures on a vehicle for commonly available equipment including snow plows. The adapter has open horizontally diverging jaws, upwardly inclined to direct the attachment plate of the equipment to be attached into a retaining slot of the adapter. The equipment is modified by having a retaining bar placed between its attachments plates to engage a latch that holds the attachments plates in their retaining slots.
The rearward portion of the adapter is an I-beam that rigidly encompasses the mounting fixtures of the vehicle and is pinned thereto through the web of the I-beam. This adapter and method provides a safe and easy method for engaging and disengaging attachments by one person from within the cab of any vehicle with no manual positioning of the attachment from outside the vehicle.

frames and mounts leave much to be de~lred in a~ much as they are difficult to ~lign and seicure to the vehicle. The plow~
have a considerable weight and can not be shifted around eiasily.
There have been many proposalqi for permltting the vehicle to be driven up to and en~aging an attachment automatically by having so~e sort of guidance and latcblng syste~ that overcomes horizontal and vertical misalignment as the ~ehicle approache~ attachment or the snow plow frame and coùplin,f~"
mechanism. Such proposals, however, have not found acceptsnce on the market for many reasons. For example, they ~ay requlre the manufacturer to modify the frame portion of the couplin,g mechanism which the manufacturer may not wi~h to do and/or require special coupling fixtures to be placed on the vehicle frame.
THIS INVENTION
The presen~t invention is addresRed to this problem and proposes an adapter couplin~ that may be semipermanently pinned to the standard or customary mounting fixture attached to the vehicle. Thi~ adapter has open, diverging ~a~s thst overcome a considerable amount of misalignment between the ertical and horizontal so that a vehicle ln spproaching an attachment to pick it up can do it so readily without a great deal,of time,b,eing wasted trying to secure an eYact closing sli~nment. The sdapter of this lnvention is usually used as ~
pair. The acqu~rin~ jsw or mouth of the adapter fits the usu~l plate or guide affixed to the fram~ of the attachment , ~:
~f 1~
20~7411 although i~ is necessary to provide on the plate or ~uide a hori~ont~l bar so that the adapter can effect vertlcal alignment.
, In brief compas9 ~ the present invention is an adapter effectin~ ready h~rizont~l and vertical al~gnment and attschment of a snowplow or auxiliary piece of equipment to a _' .,''t~
vehicle, the atta~hment havin~ left and right plates extending rearwardly for attachment to a vehicle and the vehicle ha~ing couplin~s mating with the plates and attaching thereto normally by a means of a horizontal pin. The adapter o~ this invention is deslgned to be interposed between one of the plates and its mating coupling to interconnect the two. With slight modifications in the~ jaw configuration it can be used with most known commercis11y available plows such as the Hyers, Western and Diamolld beside~ the Fisher.
The present adapter comprises;
a. A horizontal cross bar affixed to the plate with which the adapter mate~;
, ~ - b. Two ver~ical sidewalls diverging towards the plate ~ , , ~ ~ to a horizontal opening at the front thereof of st least four ~. ~, .. .
~ and~;preferably at l~east 8iX inches and closin~ at the other "~
end to~ a vertical slot of less than 1.1 inches. The lnner of ~; the two vertical sidewalls is upwardly inclined from front to ;. ~ . j , , ~ :
back at least 2 and preferably 3 inches with the slope thereof being no~greater than 1:1. The upwardly inclined wall ends in a ~horizontal slot matil)~ with the horizontal cross bar attached to the plate. The cross bar on the outer end has a 2~7~
~etainin~ rinp. The outer sidewal} may be slotted to mate with thia retaining ring.
A latch i8 l~ount~d contiguous to the horizontal ~lot in the inner ~ide wall an~ is adapted to en8age and hold the horizontal cro~ bar in the slot.
The adapter has a mounting bar fscing rearedly at the back of the vertic~l slot to rigidly slidingly enga~e one of the couplings of the vehiele and be pinned thereto.
The horizontal cross bars on the plates on the attachment or snowplow frame prefer~bly i9 a single bar running between the two or three plates on the frame.
The latch preferably i~ a pivoting clip that upwardly rotates to the open position and is sprin~ bia~ed to the normally closed position about the horizoDtal cro~s bar.
" .
P~eferably, the latch is operated by a cable pull from the cab of the vehicle. This enables one person to en8a8e or disen~a~e the adapter without leaving the cab of the vehicle ~ -providing a safe and easy method for ei~her operation of the adupter.
Other than the use of the pre~ent adapter, the hookup and operati~n of the attachment are conventional. A hydraulic cylinder is attached to the frame by a chain and hook to per~it the attachloent to be raised or lowered in the normal manner. ~

DESCRIPTION
Ref~rring to Fig. 1 a snowplow 1 has conventional mounting plate-s 2 attached to a frame 3. The plates sre rectangular in horizontal cross-sectlon. In accordance vith this invention a cross bar 4 i9 run through both plates ~ in one of the holes normally used to pin the plates into the mounting couplin~ on the frame of the vehicle.
The vehicle 10 to be attached to the snowplow ha~ mounts 5 for supportin~ a conventional hydraulic cylinder/lift chain (not shown) which is to be attached to the snowplow 1 in the usual manner. Mounts 6 extend from the frame of the vehicle esch of wh1ch consists of two arms spaced apart about one inch that normally would en8age plates 2 and be pinned thereto. As anyone who ha~ worked with snowplows knows, alignin~ the holes . ,~ , , .
in plate 2 with the corresponding pins and holes ln mounts 6 can be a devilish job especially when it is cold and the --fin~ers are numb and temper~ short.
, ~
~ The adapte~rs 7 of this invention are mounted on the ;~ mounts 6 and pinned or bolted thereto. The rearward portions of adapters 7 preferably consist of an I-beam 17, the web of whlch f`it~ between the two ar~s of mount 6 with the top and :
bottom plates fittinb snu~ly over and under mount 6 so that when pinned thereto through the web a rdther ri~id connection is made. ~- -:~ :
~ 5_ 202 ~411 ,~ , Illustrated in Fig. 1 are cable~ 8 extending from the latch mechallism of adapter 7 through the en8ine compsrtment of the vehicle to the cab ~o thst the cable pull~ 0ay be opersted fro~ the cab.
Turning to Figs. 2 and 3 the adapter of this invention will be explained in greater detail. The adapter has two ~ertical sidewalls 15 and 16. The leading edge of the inner sidewall 15 facin~ the snowplow i8 inclined upwardly 8 vertical di~tance of at least two inches st a ~lope no greater than 1:1. Sidewalls 15 and 16 extend rearedly and connect to an I-beam 17. Side wall 15 as illustrated ie offset to accommodate the ~nowplow frame and terminates ln a plate 27 which is attached to I-beam l7 and defines in part a ~lot 35.
I-beam 17 is ~ade to slide over and en8age the conventional mountlng couplin~ 6 on the vehicle. The I-beam ha~ a hole 14 in the web 18 and a spring loaded pin 20 is inserted through it and the corresponding holes in the mounting coupling 6.
Pin 20 is supported on the frame in the usual manner by a bracket 21 and hàs a handle 22 to assist in retracting the pin when attachin~ the adapter. The adapters 7 of this invention once affixed to the frame usually remain there for the wlnter~
Sidewalls 15~ and 16 diverge towards the snowplow preferably to a horizontal width of at least 4 inches which ~ives a ~reat deal of latitude in the horizontal alignment.
The two walls converge towards the rear before I-beam 17 to form a ~vertical slot 35 which receive~ plste 2. Slot 35 has .
` about the same width as the slot in mounts 6, usually sbout 1 inch. The upwardly slanting wall 15 terminates in a slot 25 ~02'~411 ,~
~` that receives cross bar 4. Bar 4 extends 8 llttle blt beyond plate 2 and i8 held therein by a retaining rin8 17 at each~
end. If bar 4 does not protrude too far on the outside of plate 2 then only the inner wall 15 need be inclined to pick up the bar. As illuQtrated, wall 16 is slotted st 23 to receive retaini~g ring 17.
A clip 26 engages and holds bar 4 once lt i8 in place in slot 25. It is sprin~ biased by a spring 29 to be normallg closed and is preferably operated by a cable 19 throu~h cable connector 8 going to the cab of the ~ehicle.
The catch or clip 26 is mounted for upward rotatlon on plate 27 by a pin 28. Sprin~ 24 is also mounted on plate 27.
As shown in Fi8. 3. rod 4 may consi~t of two ends threaded illto a tightenin~ nut 40 which assists in ti~htening securing rod 4 to plates 2.
~
:~ In operation, to detach the snowplow a pipestand 31 (Fig.
1) is dropped to support the snowplow. The operator pu118 the cable release~ 19 to lift up clips 26 and then simply backs -~ the vehicle away. To attach the snowplow all` thst i8 neceesary is to drive up to the snowplow with some reasonable de~ree of :ali~n~ent and to continue forward at a 810w pace to a~llow the :sidewalls l5 and 16 of the adapter 7 to plck up bar ~u~ 4 and to encompass plate 2. Further .forward ~otion of the vehicle causes plate 2 to be ~uided into the vertical slot 35 provided by the sidewall and to lift bar 4 up and into slot 25. Clip 26 will be pushed up and when bar 4 ~9 in place ln slot 25 will auto~atically drop down and hold bar 4. If the "" ~
