Abstract
Abstract A universal coupling has two coupling forks; each fork is an integral unit with two fork eyes; an opening in each eye for receiving a bearing sleeve; a crosspiece with pins thereon, each pin to be received in a bearing sleeve; each bearing sleeve has a base; a bore through the crosspiece and extending along the axes of two aligned pins thereof; an aligned bore in the base of each bearing sleeve; a tie rod extends through the bores in the bearing sleeve bases and the crosspiece; a guide sleeve holds the tie rod at the other fork eye from the fork eye having a bearing sleeve installed; a pressure applying piston and cylinder connected between the tie rod and one of the bearing sleeves is operated for moving that bearing sleeve into the fork eye opening.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
193 words
A method of assembling a coupling fork of a universal coupling of the type comprised of two coupling forks, wherein the coupling fork is a single piece unit having two fork eyes, and the coupling includes a crosspiece having four pins, and each pair of crosspiece pins being on a respective axis, and the crosspiece having a bore therein which extends along the axis of a pair of the pins; the method being for mounting a bearing having a bearing sleeve for pivotally supporting a pin of the crosspiece of the coupling, and the pin being mounted in the bearing sleeve in the fork eye; the method comprising: inserting a tie rod in the bore in the crosspiece and extending along the axis of the pair of the pins; supporting the tie rod in a fixed position one fork eye, while passing the tie rod through a bore which passes through the bearing sleeve for the bearing at the other fork eye to align the pin therein; then pressing the bearing sleeve, through which the tie rod passes, into an opening provided therefor in the other fork eye and about the pin therein.
Claim 2
Independent Claim
193 words
A method of assembling a coupling fork of a universal coupling of the type comprised of two coupling forks, wherein the coupling fork is a single piece unit having two fork eyes, and the coupling includes a crosspiece having four pins, and each pair of crosspiece pins being on a respective axis, and the crosspiece having a bore therein which extends along the axis of a pair of the pins; the method being for mounting a bearing having a bearing sleeve for pivotally supporting a pin of the crosspiece of the coupling, and the pin being mounted in the bearing sleeve in the fork eye; the method comprising: inserting a tie rod in the bore in the crosspiece and extending along the axis of the pair of the pins; supporting the tie rod in a fixed position one fork eye, while passing the tie rod through a bore which passes through the bearing sleeve for the bearing at the other fork eye to align the pin therein; then pressing the bearing sleeve, through which the tie rod passes, into an opening provided therefor in the other fork eye and about the pin therein.
Claim 3
Dependent Claim
75 words
The method of assembling a coupling fork of claim 1, further comprising, before inserting the tie rod, centering the crosspiece with the one fork eye by inserting a removable guide sleeve into an opening provided therefor in the one fork eye; the inserting of the tie rod including inserting the tie rod through the one fork eye and the tie rod being supported at the one fork eye by being supported at the guide sleeve.
Claim 4
Dependent Claim
111 words
The method of assembling a coupling fork of claim 2, wherein during the centering of the crosspiece with the one fork eye, initially arranging the crosspiece off center from the axis of rotation of the respective coupling fork and locating the crosspiece slighty nearer to the one fork eye; pressing the bearing sleeve further into the other fork eye by the distance which the crosspiece is off center; securing the bearing sleeve relative to the axis of rotation of the coupling fork; then operating the tie rod for moving the crosspiece and the bearing sleeve together into a central position with respect to the axis of rotation of the coupling fork.
Claim 5
Independent Claim
73 words
The method of assembling a coupling fork of any of claims 1, 2, or 3, wherein prior to inserting the tie rod, forming a bore in the crosspiece and extending along the axis of the pair of pins of the crosspiece, the bore being for receiving the tie rod; forming a bore, alignable with the bore in the crosspiece, in the bearing sleeve, through which bearing sleeve bore the tie rod may pass.
Claim 6
Dependent Claim
83 words
The method of assembling a coupling fork of claim 4, wherein prior to inserting the tie rod, forming a respective opening extending through each fork eye and the openings in the fork eyes being alignable with the bore in the crosspiece, whereby a respective bearing sleeve may be inserted in each fork eye opening; inserting a bearing sleeve in the opening in the other fork eye, with the bore in the bearing sleeve being aligned with the opening in the other fork eye.
Claim 7
Dependent Claim
47 words
The method of assembling a coupling fork of claim 5, wherein the pins have external diameters; the diameters of the bores in the crosspiece and of the bore in the bearing sleeve is in the range of 0.25 to 0.4 times the external diameters of the pins.
