Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 241 words
A hitch for connection to a pair of rotary lawn mowers each having a generally vertical plate secured thereto and extending transversely to the towing direction, each said plate including generally horizontal portions positioned in front of such mowers and having swivelable rotatable wheels thereon for supporting such mowers, said hitch comprising a rigid bar elongated transversely to the direction of towing and having first and second ends separated by an intermediate section, said first end and said intermediate section defining an adjustable connecting portion, said bar having generally horizontal and vertical bar surfaces, a first connecting device adjustably connected to said connecting portion of said bar and having a generally horizontal surface overlying said generally horizontal bar surface and a generally vertical surface spaced from and parallel to said generally vertical bar surface, the top edge of one of said flanges on one of said mowers being positioned between said generally vertical surfaces, a second connecting device on said second end of said bar connected with the other of said flanges on the other of said mowers, a plurality of spaced openings through said flanges for receiving pins to adjustably connect said flanges with said connecting devices, wheel means positioned proximate said second end of said bar for supporting same, drawing means connectable to a towing device coupled to said bar, and one of said connecting devices being spaced rearwardly of said bar from the other of said connecting devices.
Claim 2
Dependent Claim 241 words
A hitch for connection to a pair of rotary lawn mowers each having a generally vertical plate secured thereto and extending transversely to the towing direction, each said plate including generally horizontal portions positioned in front of such mowers and having swivelable rotatable wheels thereon for supporting such mowers, said hitch comprising a rigid bar elongated transversely to the direction of towing and having first and second ends separated by an intermediate section, said first end and said intermediate section defining an adjustable connecting portion, said bar having generally horizontal and vertical bar surfaces, a first connecting device adjustably connected to said connecting portion of said bar and having a generally horizontal surface overlying said generally horizontal bar surface and a generally vertical surface spaced from and parallel to said generally vertical bar surface, the top edge of one of said flanges on one of said mowers being positioned between said generally vertical surfaces, a second connecting device on said second end of said bar connected with the other of said flanges on the other of said mowers, a plurality of spaced openings through said flanges for receiving pins to adjustably connect said flanges with said connecting devices, wheel means positioned proximate said second end of said bar for supporting same, drawing means connectable to a towing device coupled to said bar, and one of said connecting devices being spaced rearwardly of said bar from the other of said connecting devices.
Claim 3
Dependent Claim 68 words
The hitch of claim 1 wherein said second end of said bar includes a rearwardly extending rigid support and said second connecting device includes a vertical portion overlapping a portion of said support in spaced relationship thereto to define a downwardly opening space for receiving the upper edge of the other of said flanges to tow the other of said mowers in trailing relationship to said one mower.
Claim 4
Dependent Claim 121 words
A hitch for lawn mowers and the like, said hitch being generally L-shaped in plan view and including a horizontal bar and a rigid frame extending rearwardly from one end of said bar, connections on the other end of said bar and the outer end of said rigid frame, each said connection including a substantially vertical connecting plate elongated generally parallel to said bar for positioning over and behind an upstanding plate on the front of a lawn mower or the like for towing such mower by force transmitted from said connecting plate to the upstanding plate on the mower when said hitch is pulled, and means on said bar intermediate said connections for attaching said hitch to a towing device.
Claim 5
Dependent Claim 121 words
A hitch for lawn mowers and the like, said hitch being generally L-shaped in plan view and including a horizontal bar and a rigid frame extending rearwardly from one end of said bar, connections on the other end of said bar and the outer end of said rigid frame, each said connection including a substantially vertical connecting plate elongated generally parallel to said bar for positioning over and behind an upstanding plate on the front of a lawn mower or the like for towing such mower by force transmitted from said connecting plate to the upstanding plate on the mower when said hitch is pulled, and means on said bar intermediate said connections for attaching said hitch to a towing device.
Claim 6
Dependent Claim 36 words
The hitch of claim 3 wherein said connections include additional surfaces spaced from said connecting plates to define downwardly opening spaces for receiving the upper edge portions of upstanding plates on lawn mowers or the like.
Claim 7
Dependent Claim 48 words
The hitch of claim 3 wherein said bar has a plurality of spaced-apart holes therealong from said other end thereof for adjusting said connection on said other end of said bar toward anD away from said connection on said rigid frame to vary the spacing between said connections.
Claim 8
Dependent Claim 26 words
The hitch of claim 3 wherein said bar comprises an angle iron and said rigid frame includes spaced-apart rearwardly extending angle irons welded to said bar.
Claim 9
Dependent Claim 33 words
