US4964224A — Shaft alignment apparatus

Claim 1

Independent Claim 312 words

A shaft alignment apparatus for coaxial alignment of spaced first and second shafts comprising, a clamp means for securement about the first shaft mounting a support rod extending above said clamp means, and a first clamp member secured to the support rod, and the first clamp member securing an alignment rod proximate a first end thereof orthogonally relative to the support rod, and a second clamp member secured to the alignment rod proximate a second end thereof spaced from the first end, and a dial indicator secured to a dial indicator shaft, the dial indicator shaft secured to the second clamp member, orthogonally relative to the alignment rod overlying the second shaft, and wherein the clamp means includes a "W" shaped yoke with a central plate including spaced parallel forward and rear edges with the forward edge mounting a forward plate and the rear edge mounting a rear plate with the forward and rear plates spaced parallel relative to one another and of equal configuration, the forward and rear plates define first and second pairs of legs aligned relative to one another and extending downwardly relative an upper surface of the support plate at an acute angle thereto, and the first and second pairs of legs in each include first and second pairs of ears respectively with each of the first and second pairs of ears extending upwardly therefrom, the first and second pairs of ears including pairs of first and second apertures directed through the respective first and second ears, the first apertures coaxially aligned relative to one another and of a first diameter and the second apertures coaxially aligned relative to one another and of an equal first diameter, and the first and second apertures rotatably mounting a respective first and second pivot cylinder, and the first and second pivot cylinder mounting a chain for securement about the first shaft.

Claim 2

Dependent Claim 312 words

A shaft alignment apparatus for coaxial alignment of spaced first and second shafts comprising, a clamp means for securement about the first shaft mounting a support rod extending above said clamp means, and a first clamp member secured to the support rod, and the first clamp member securing an alignment rod proximate a first end thereof orthogonally relative to the support rod, and a second clamp member secured to the alignment rod proximate a second end thereof spaced from the first end, and a dial indicator secured to a dial indicator shaft, the dial indicator shaft secured to the second clamp member, orthogonally relative to the alignment rod overlying the second shaft, and wherein the clamp means includes a "W" shaped yoke with a central plate including spaced parallel forward and rear edges with the forward edge mounting a forward plate and the rear edge mounting a rear plate with the forward and rear plates spaced parallel relative to one another and of equal configuration, the forward and rear plates define first and second pairs of legs aligned relative to one another and extending downwardly relative an upper surface of the support plate at an acute angle thereto, and the first and second pairs of legs in each include first and second pairs of ears respectively with each of the first and second pairs of ears extending upwardly therefrom, the first and second pairs of ears including pairs of first and second apertures directed through the respective first and second ears, the first apertures coaxially aligned relative to one another and of a first diameter and the second apertures coaxially aligned relative to one another and of an equal first diameter, and the first and second apertures rotatably mounting a respective first and second pivot cylinder, and the first and second pivot cylinder mounting a chain for securement about the first shaft.

Claim 3

Dependent Claim 86 words

A shaft alignment apparatus as set forth in claim 1 wherein the first pivot cylinder includes a threaded bore extending diametrically through the first pivot cylinder, and the threaded bore threadedly receiving a "J" shaped hook, the "J" shaped hook formed with an upwardly turned leg spaced from a shank defined by the hook a fixed distance, wherein the fixed distance is substantially equal to a diameter defined by a chain axle, the chain including a series of links, and each link including spaced chain axles.

Claim 4

Dependent Claim 75 words

A shaft alignment apparatus as set forth in claim 2 wherein the second pivot cylinder includes a smooth bore diametrically directed therethrough for slidingly receiving a threaded shank, the threaded shank integrally secured to a forward terminal end of the chain, and a securement means cooperating with the threaded shank to enable tightening of the chain about the first shaft when the threaded shank is directed through the smooth bore of the second pivot cylinder.

Claim 5

Dependent Claim 75 words

A shaft alignment apparatus as set forth in claim 3 wherein each pivot cylinder includes a main body of a first diameter greater than a diameter defined by the first and second apertures and each pivot cylinder further including coaxially aligned axles of a diameter substantially equal to the diameter defined by the apertures, and each pivot cylinder of a length substantially equal to a spacing defined between the legs of the "W" shaped clamp.

Claim 6

Dependent Claim 172 words

A shaft alignment apparatus as set forth in claim 4 wherein the first clamp and the second clamp are of duplicate configuration, and the first clamp includes a first bore for receiving the support rod therethrough, the first bore aligned with and in communication with a second slot extending orthogonally through a first end of the first clamp, and a fourth bore formed orthogonally relative to the first bore for receiving the alignment rod therethrough and the fourth bore coextensive with and in communication with a first slot orthogonally aligned relative to the second slot, and the first and second slots each receiving a clamping member orthogonally through the first and second slots to squeeze opposed portions of the first clamp spaced on opposed sides of the first and second slots and thereby clamp the respective support rod and alignment rod within the respective first and fourth bores, and the clamping members directed through respective second and third bores to receive the clamping members relative to the respective first and second slots.

Claim 7

Dependent Claim 55 words

A shaft alignment apparatus as set forth in claim 5 wherein the forward plate of the "W" shaped yoke includes a further alignment rod directed orthogonally relative to the forward plate and orthogonally relative to the threaded bore directed through the support plate, wherein the further alignment rod is positioned medially of the forward plate.
