Abstract

Abstract Apparatus for use in the connection between two vehicles for adjustment to different heights to attain desired levels of each vehicle without prewelding. The apparatus includes a device for selectively positioning a trailer hitch at any one of a number of different levels on a tow vehicle so that the hitch can be properly located for connection with a hitch on a trailer to be towed. The device includes a first member having a pair of spaced, grooved sides between which is removably received a second, ribbed member removably received between the grooved sides of the first member. Pin means is used to connect the first and second members together, the sides of the first member extending up and down so that the second member can be received at different heights above the ground.

A trailer hitch comprising: a pintle adapted to be coupled in a generally horizontal position to a first vehicle, an elongated receiver having a generally vertically disposed open end and adapted to be connected to a second vehicle, said receiver and said pintle having cooperating tongue and groove means thereon to permit the pintle to be inserted into the receiver through said open end and removably retained therein at any one of a number of operative locations along the length thereof, and means engageable with the receiver and the pintle for interconnecting the same when the pintle is at any one of said operative locations.
Claim 2
Dependent Claim 105 words
A trailer hitch comprising: a pintle adapted to be coupled in a generally horizontal position to a first vehicle, an elongated receiver having a generally vertically disposed open end and adapted to be connected to a second vehicle, said receiver and said pintle having cooperating tongue and groove means thereon to permit the pintle to be inserted into the receiver through said open end and removably retained therein at any one of a number of operative locations along the length thereof, and means engageable with the receiver and the pintle for interconnecting the same when the pintle is at any one of said operative locations.
Claim 3
Dependent Claim 39 words
A trailer hitch as set forth in claim 1, wherein said receiver has a pair of opposed, spaced generally vertical sides defining the open end, the grooves of said structure extending across substantially the entire widths of said sides.
Claim 4
Dependent Claim 51 words
A trailer hitch as set forth in claim 1, wherein said pintle is disposed transversely of the length of said receiver when the pintle is inserted therein, said cooperating means including structure extending across substantially the entire width of the receiver for restraining the pintle against movement along said receiver length.
Claim 5
Dependent Claim 147 words
Apparatus for interconnecting a pair of vehicles comprising: a first, elongated generally vertically disposed member having a generally vertically disposed open end and means thereon for coupling the same to a first vehicle; a second member adapted to be coupled to a second vehicle, said first member having means defining a plurality of spaced generally horizontal grooves transversely of the length thereof and extending substantially to said open end, the second member being receivable through said open end into said first member and having means defining tongue structure insertable into any one of a number of groups of said grooves when the second member is received in the first member to thereby removably restrain the second member against movement in a direction longitudinally of the first member; and means engageable with the members for interconnecting the same when the second member is received in the first member.
Claim 6
Dependent Claim 147 words
Apparatus for interconnecting a pair of vehicles comprising: a first, elongated generally vertically disposed member having a generally vertically disposed open end and means thereon for coupling the same to a first vehicle; a second member adapted to be coupled to a second vehicle, said first member having means defining a plurality of spaced generally horizontal grooves transversely of the length thereof and extending substantially to said open end, the second member being receivable through said open end into said first member and having means defining tongue structure insertable into any one of a number of groups of said grooves when the second member is received in the first member to thereby removably restrain the second member against movement in a direction longitudinally of the first member; and means engageable with the members for interconnecting the same when the second member is received in the first member.
Claim 7
Dependent Claim 134 words
Apparatus for interconnecting a pair of vehicles comprising: a first, elongated member having a pair of spaced, generally vertical sides and adapted to be coupled to a vehicle to be towed; a second, elongated, generally horizontal member adapted to be coupled to a tow vehicle, said first member having an open, longitudinally extending front defining an entry for the insertion of the second member between the sides of the first member at any one of a number of operative locations along the same; tongue and groove structure on the members for restraining the second member against movement longitudinally of the first member when the second member is between said sides; and means for interconnecting the first and second members when the second member is at any one of said locations within the second member.
Claim 8
Dependent Claim 134 words
Apparatus for interconnecting a pair of vehicles comprising: a first, elongated member having a pair of spaced, generally vertical sides and adapted to be coupled to a vehicle to be towed; a second, elongated, generally horizontal member adapted to be coupled to a tow vehicle, said first member having an open, longitudinally extending front defining an entry for the insertion of the second member between the sides of the first member at any one of a number of operative locations along the same; tongue and groove structure on the members for restraining the second member against movement longitudinally of the first member when the second member is between said sides; and means for interconnecting the first and second members when the second member is at any one of said locations within the second member.
Claim 9
Dependent Claim 174 words
Apparatus for interconnecting a pair of vehicles comprising: a first, elongated member having a pair of spaced sides and adapted to be coupled to a vehicle to be towed; a second, elongated member adapted to be coupled member a two vehicle, said first member having an open, longitudinally extending front defining an entry for the insertion of the second member between the sides of the first member at any one of a number of operative locations along the same, said sides having a plurality of spaced grooves therein, there being a groove on one side aligned with a groove on the other side, said second member having a pair of tongues receivable within any one of the pairs of grooves for restraining the second member against movement longitudinally of the first member when the second member is between said sides; and a pin removably extending through one of the members and into the other member for interconnecting the members when the second member is at any one of said locations along the first member.
Claim 10
Dependent Claim 174 words
Apparatus for interconnecting a pair of vehicles comprising: a first, elongated member having a pair of spaced sides and adapted to be coupled to a vehicle to be towed; a second, elongated member adapted to be coupled member a two vehicle, said first member having an open, longitudinally extending front defining an entry for the insertion of the second member between the sides of the first member at any one of a number of operative locations along the same, said sides having a plurality of spaced grooves therein, there being a groove on one side aligned with a groove on the other side, said second member having a pair of tongues receivable within any one of the pairs of grooves for restraining the second member against movement longitudinally of the first member when the second member is between said sides; and a pin removably extending through one of the members and into the other member for interconnecting the members when the second member is at any one of said locations along the first member.
Claim 11
Dependent Claim 173 words
