Abstract
Abstract The hitch attachment is adapted for use with a type of hitch apparatus now in general use for connecting the tongue of a stock trailer or the like with the floor of the box of a pickup truck. In this hitch apparatus a hitch ball secured to and projected upwardly from the box floor is received within a ball socket carried at the lower end of a front upright section that forms part of a tongue structure of a gooseneck type. The attachment is of a greater length than the front upright section and is pivoted at one end to the top of the upright section for swinging movement to a first storage position extended rearwardly from the top of the upright section for support on the upper side of the tongue structure and to a second working position projected longitudinally of and downwardly from the upright section. In this second position a hitch ball on the attachment is received in locked engagement within the ball socket on the upright section and a clevis at the lower end of the attachment is connectible with the draw bar of a farm tractor.

Claim 1
Independent Claim
203 words
A hitch attachment for converting the hitch apparatus of a vehicle-trailer combination for connection of the trailer with the draw bar of a farm tractor wherein said trailer includes a frame having a tongue structure with a front upright section and a hitch ball-receiving socket at the lower end of said front section, and said vehicle has a hitch ball receivable in said socket, said hitch attachment comprised of: a. an elongated body member having a hitch ball mounted intermediate the ends thereof and facing one end thereof and a clevis member secured to the opposite end of said body member, and b. means for movably connecting the one end of said body member to the upper portion of said front section to provide for movement of the body member to a first position extended longitudinally of said front section and projected downwardly therefrom and to a second position extended rearwardly from said upper portion for resting engagement on the top side of the tongue structure, c. said hitch ball in the body member, in said first position of the body meMber, being receivable in locking engagement within said hitch ball-receiving socket, and said draw bar receivable within said clevis for connection therewith.
Claim 2
Dependent Claim
203 words
A hitch attachment for converting the hitch apparatus of a vehicle-trailer combination for connection of the trailer with the draw bar of a farm tractor wherein said trailer includes a frame having a tongue structure with a front upright section and a hitch ball-receiving socket at the lower end of said front section, and said vehicle has a hitch ball receivable in said socket, said hitch attachment comprised of: a. an elongated body member having a hitch ball mounted intermediate the ends thereof and facing one end thereof and a clevis member secured to the opposite end of said body member, and b. means for movably connecting the one end of said body member to the upper portion of said front section to provide for movement of the body member to a first position extended longitudinally of said front section and projected downwardly therefrom and to a second position extended rearwardly from said upper portion for resting engagement on the top side of the tongue structure, c. said hitch ball in the body member, in said first position of the body meMber, being receivable in locking engagement within said hitch ball-receiving socket, and said draw bar receivable within said clevis for connection therewith.
Claim 3
Dependent Claim
85 words
The hitch attachment according to claim 1, wherein: a. the distance between the ball member on said body member and the one end of said body member is substantially equal to the length of said front section, and b. the distance between the hitch ball on the body member and the opposite end of the body member is such that when the body member is in the first position and connected with the tractor draw bar the trailer frame is in a substantially horizontal position.
Claim 4
Dependent Claim
57 words
The hitch attachment according to claim 1, wherein: a. said body member is formed of a pair of transversely spaced side members and said body member hitch ball is positioned between said side members whereby on movement of the body member to said first position said side members are located at opposite sides of said front section.
Claim 5
Dependent Claim
199 words
A hitch attachment providing for the connection with the draw bar of a farm tractor of a vehicle trailer having a tongue structure with a forwardly and downwardly inclined section terminating in an upright front section having a hitch ball-receiving socket at the lower end thereof, said attachment including: a. a pair of transversely spaced side members, b. a hitch ball located between and mounted on said members intermediate the ends thereof so as to extend toward one of the ends of said side members, c. a clevis unit located outwardly from and connected to the other ends of said side members, and d. means for movably connecting the one ends of said side members to the top portion of said upright section to provide for movement of said attachment to a first position extended longitudinally of and above said inclined section and to a second position extended longitudinally of said front section so as to constitute a downward extension thereof, e. said hitch ball, in said second position, being receivable in said ball-receiving socket to releaseably lock the attachment against movement relative to said front section and said draw bar being receivable within said clevis for connection therewith.
Claim 6
Dependent Claim
199 words
A hitch attachment providing for the connection with the draw bar of a farm tractor of a vehicle trailer having a tongue structure with a forwardly and downwardly inclined section terminating in an upright front section having a hitch ball-receiving socket at the lower end thereof, said attachment including: a. a pair of transversely spaced side members, b. a hitch ball located between and mounted on said members intermediate the ends thereof so as to extend toward one of the ends of said side members, c. a clevis unit located outwardly from and connected to the other ends of said side members, and d. means for movably connecting the one ends of said side members to the top portion of said upright section to provide for movement of said attachment to a first position extended longitudinally of and above said inclined section and to a second position extended longitudinally of said front section so as to constitute a downward extension thereof, e. said hitch ball, in said second position, being receivable in said ball-receiving socket to releaseably lock the attachment against movement relative to said front section and said draw bar being receivable within said clevis for connection therewith.
Claim 7
Dependent Claim
