Abstract

Abstract A fork lift type device for attachment to a three point hitch of a tractor and having a hydraulic cylinder connected to the upper point of the hitch for controlling the tilt of the fork lift. A vertical frame forms a base for supporting horizontally extending fork members. A vertically disposed square sleeve is rigidly affixed to the frame and a post member is received in one end of the sleeve. A pin selectively affixes the sleeve and post members together. The top of the post member has an apertured plate extending in one direction, for connection to the hydraulic cylinder, and a clevis structure extends in an opposite direction for allowing connection to a conventional three point hitch upper rod when the post member is turned 180 degrees. The sleeve member is open at each end so as to receive the post member in either end to thereby facilitate the turning of the fork lift structure over and thereby allowing a higher lifting capability to the fork lift.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 173 words
An item transporting device, adapted to be connected to a tractor three point hitch of the type having two parallel draft arms with rearwardly extending ends and a fixed pivotal point above and between the draft arms, comprising: a laterally extending frame; at least one longitudinally extending fork lift member attached to said frame and extending rearwardly therefrom; first means for pivotally connecting the frame to the rearwardly extending ends of the draft arms; a connection member pivotally connected at one end thereof to the fixed pivotal point of the three point hitch; and second means connected to said frame, above said first means, for pivotally connecting the other end of said connection member to said frame, said second means comprising: a sleeve connected to said frame; a post member slidably received in one end of said sleeve; means for releasably fixing the position of said post member with respect to said sleeve; and an apertured forwardly extending plate affixed to one end of said post member pivotally connected to said connection member.
Claim 2
Dependent Claim 173 words
An item transporting device, adapted to be connected to a tractor three point hitch of the type having two parallel draft arms with rearwardly extending ends and a fixed pivotal point above and between the draft arms, comprising: a laterally extending frame; at least one longitudinally extending fork lift member attached to said frame and extending rearwardly therefrom; first means for pivotally connecting the frame to the rearwardly extending ends of the draft arms; a connection member pivotally connected at one end thereof to the fixed pivotal point of the three point hitch; and second means connected to said frame, above said first means, for pivotally connecting the other end of said connection member to said frame, said second means comprising: a sleeve connected to said frame; a post member slidably received in one end of said sleeve; means for releasably fixing the position of said post member with respect to said sleeve; and an apertured forwardly extending plate affixed to one end of said post member pivotally connected to said connection member.
Claim 3
Dependent Claim 40 words
The device as defined in claim 1 wherein a clevis extends on the opposite side of the post member; and said post member has means thereon for selectively allowing 180° repositioning of said post member with respect to said sleeve.
Claim 4
Dependent Claim 24 words
The device as defined in claim 1 including means for permitting the post member to be received in the other end of the sleeve.
Claim 5
Dependent Claim 19 words
