Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
150 words
A wheel support for an overhead crane comprising: (a) a shaft having a wheel carrying curved surface; (b) anti-friction bearings, said shaft being rotatably supported by said bearings; (c) bushings for supporting said bearings; (d) an oil duct extending into said shaft, said oil duct exiting said shaft at said curved surface of said shaft; (e) a wheel having a central bore hole, a portion of the central bore hole of said wheel overlying said curved surface of said shaft where said oil duct exits from said shaft; (f) an oil pressure providing means for supplying oil, under pressure, to said oil duct and to said portion of the central bore hole of said wheel; (g) said bushings being provided with selectively secured positioning means; and (h) selected spacer ring members are provided between said positioning means and said bearings for adjustably positioning said bearings with respect to said bushings.
Claim 2
Dependent Claim
150 words
A wheel support for an overhead crane comprising: (a) a shaft having a wheel carrying curved surface; (b) anti-friction bearings, said shaft being rotatably supported by said bearings; (c) bushings for supporting said bearings; (d) an oil duct extending into said shaft, said oil duct exiting said shaft at said curved surface of said shaft; (e) a wheel having a central bore hole, a portion of the central bore hole of said wheel overlying said curved surface of said shaft where said oil duct exits from said shaft; (f) an oil pressure providing means for supplying oil, under pressure, to said oil duct and to said portion of the central bore hole of said wheel; (g) said bushings being provided with selectively secured positioning means; and (h) selected spacer ring members are provided between said positioning means and said bearings for adjustably positioning said bearings with respect to said bushings.
Claim 3
Dependent Claim
24 words
A wheel support as claimed in claim 1, wherein: (a) said portion of said central bore hole of said wheel is a cylindrical recess.
Claim 4
Dependent Claim
40 words
A wheel support as claimed in claim 1, wherein: (a) a portion of said curved surface of said shaft is provided with a cylindrical recess; and (b) said portion of the central bore of said wheel overlying said cylindrical recess.
Claim 5
Dependent Claim
33 words
A wheel support as claimed in claim 1, wherein: (a) said oil pressure providing means is a pressure providing screw; and (b) said screw being adjustably threaded into one end of said shaft.
Claim 6
Dependent Claim
44 words
A wheel support as claimed in claim 1, wherein: (a) said bushings are provided with annular grooves; (b) said positioning means are spring-type retaining rings received within said grooves; and (c) said spacer ring members are positioned between said retaining rings and said bearings.
Claim 7
Dependent Claim
20 words
A wheel support as claimed in claim 5, wherein: (a) spacer rings are provided between said wheel and said bearings.
Claim 8
Dependent Claim
21 words
A wheel support as claimed in claim 6, wherein: (a) said spacer rings are received within annular grooves of said wheel.
Claim 9
Dependent Claim
35 words
A wheel support as claimed in claim 1, wherein said shaft is provided with a multi-wedge serration at the end of said shaft opposite said wheel, said serration securing a driving gear for said shaft.
Claim 10
Dependent Claim
