Abstract
Abstract A detachable hitch for use on an elongated frame including a front portion formed of an angled interconnection of two load bearing members and a rear portion formed of two additional load bearing members in angled relation, the front and rear portions interconnected by overlapping plates attached to the respective portions, with the front portion supporting a towing device and the rear portion interconnected with longitudinal load bearing members of the frame to thus form a structurally sound hitch yet allow detachability of the front portion from the rear portion by the separation of the connection plates.

Claim 1
Independent Claim
596 words
A detachable hitch for use with elongated frames having at least two longitudinal, load bearing, support, main members extending substantially the length of the frame in a common plane and a plurality of cross members not having substantial load bearing capacity arranged transverse to the main members, including: a first set of longitudinal load bearing members including a first longitudinal member having first and second ends and a second longitudinal member having first and second ends with the first and second longitudinal members interconnected in a generally horizontal plane with the first ends of the first and second members connected together in a manner arranged to project forwardly of the frame and with the second ends of the first and second members separated, angled with respect to one another, and arranged to lie adjacent the frontmost cross member of the frame; a towing device fixed to the interconnection of the first ends of the first and second members; a first connection plate connected to the second end of the first member adjacent the bottom; a second connection plate connected to the second end of the second member adjacent the bottom; a second set of longitudinal load bearing members including third longitudinal member having first and second ends and a fourth longitudinal member having first and second ends with the first end of the third member arranged to interconnect with a main frame support member in a manner to cause the second end of the third member to extend forwardly of the frame in the plane of the main members with the second end terminating adjacent the second end of the first member but on the opposite side of the front cross member and with the first end of the fourth member arranged to interconnect to the other main frame support member in a manner to cause the second end of the fourth member to extend forwardly of the frame in the plane of the main members, with the second end of the fourth member terminating adjacent the second end of the second member but on the opposite side of the front cross member from the second member; a third connection plate connected to the second end of the third member adjacent the bottom and arranged to overlie the first connection plate connected to the first member and allow the interconnection of the first member and the third member into a single unitary structural member through the interconnection of the third connection plate and the first connection plate to thus allow the transferring of forces from the first end of the first member to the first end of the third member and thus to the main frame support member without relianCe upon the front or any other cross member; a fourth connection plate connected to the second end of the fourth member adjacent the bottom and arranged to overlie the second connection plate connected to the second member and allow the interconnection of the second member and the fourth member into a single unitary structural member through the interconnection of the second connection plate and the fourth connection plate to thus allow the transferring of forces from the first end of the second member to the first end of the fourth member and thus to the main frame support member without reliance upon the front or any other cross member to form a structurally sound hitch yet allow the detachability of the first and second members from the third and fourth members by separating the first and third connection plates and the second and fourth connection plates.
Claim 2
Dependent Claim
596 words
A detachable hitch for use with elongated frames having at least two longitudinal, load bearing, support, main members extending substantially the length of the frame in a common plane and a plurality of cross members not having substantial load bearing capacity arranged transverse to the main members, including: a first set of longitudinal load bearing members including a first longitudinal member having first and second ends and a second longitudinal member having first and second ends with the first and second longitudinal members interconnected in a generally horizontal plane with the first ends of the first and second members connected together in a manner arranged to project forwardly of the frame and with the second ends of the first and second members separated, angled with respect to one another, and arranged to lie adjacent the frontmost cross member of the frame; a towing device fixed to the interconnection of the first ends of the first and second members; a first connection plate connected to the second end of the first member adjacent the bottom; a second connection plate connected to the second end of the second member adjacent the bottom; a second set of longitudinal load bearing members including third longitudinal member having first and second ends and a fourth longitudinal member having first and second ends with the first end of the third member arranged to interconnect with a main frame support member in a manner to cause the second end of the third member to extend forwardly of the frame in the plane of the main members with the second end terminating adjacent the second end of the first member but on the opposite side of the front cross member and with the first end of the fourth member arranged to interconnect to the other main frame support member in a manner to cause the second end of the fourth member to extend forwardly of the frame in the plane of the main members, with the second end of the fourth member terminating adjacent the second end of the second member but on the opposite side of the front cross member from the second member; a third connection plate connected to the second end of the third member adjacent the bottom and arranged to overlie the first connection plate connected to the first member and allow the interconnection of the first member and the third member into a single unitary structural member through the interconnection of the third connection plate and the first connection plate to thus allow the transferring of forces from the first end of the first member to the first end of the third member and thus to the main frame support member without relianCe upon the front or any other cross member; a fourth connection plate connected to the second end of the fourth member adjacent the bottom and arranged to overlie the second connection plate connected to the second member and allow the interconnection of the second member and the fourth member into a single unitary structural member through the interconnection of the second connection plate and the fourth connection plate to thus allow the transferring of forces from the first end of the second member to the first end of the fourth member and thus to the main frame support member without reliance upon the front or any other cross member to form a structurally sound hitch yet allow the detachability of the first and second members from the third and fourth members by separating the first and third connection plates and the second and fourth connection plates.
Claim 3
Dependent Claim
114 words
The detachable hitch of claim 1, wherein the connection plates define apertures therein, with the apertures defined within the first and third connection plates overlying one another and arranged to receive bolts therethrough and the apertures defined within the first and fourth connection plates overlying one another and arranged to receive bolts therethrough to thereby firmly interconnect the first and the third connection plates and the second and the fourth connection plates to form a structurally sound hitch yet allow the detachability of the first and second members from the third and fourth members by the removal of bolts thus separating the first and third connection plates and the second and fourth connection plates.
Claim 4
Dependent Claim
19 words
The detachable hitch of claim 2, wherein the towing device comprises a socket arranged to receive a towing ball.
Claim 5
Dependent Claim
15 words
The detachable hitch of claim 3, wherein the first and second members comprise channel iron.
Claim 6
Dependent Claim
19 words
The detachable hitch of claim 1, wherein the towing device is a socket arranged to receive a towing ball.
