Abstract
Abstract An axle adaptor for providing a temporary replacement axle spindle on an axle from which the original spindle has fractured comprises a replacement spindle welded at its inner end to a cup defining an inwardly facing recess for receiving the end of the original axle shaft. A bracing angle member is secured externally to the cup and extends inwardly. A shaft-clamping shackle effectively comprising a U-bolt is provided toward the inner end of the angle member for firmly clamping the adaptor to the existing axle shaft. Radially extending clamping bolts usefully extend through the wall of the cup to provide additional clamping action.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
146 words
An axle adaptor which comprises: an axle spindle having inner and outer ends and formed at said inner end thereof with a larger diameter portion; a cup secured to said axle spindle at said inner end thereof and defining a generally cylindrical recess essentially coaxial with said spindle, facing inwardly for receiving the end of a broken axle shaft on which said adaptor can be secured and having a diameter essentially equal to the diameter of said larger diameter portion of said axle spindle; a bracing member having inner and outer ends and secured at said outer end thereof to said cup externally thereof to extend inwardly therefrom and generally parallel to said axle spindle; and a shackle on said bracing member toward said inner end thereof for securing said adaptor on an axle shaft with said axle spindle essentially coaxial with such an axle shaft.
Claim 2
Dependent Claim
146 words
An axle adaptor which comprises: an axle spindle having inner and outer ends and formed at said inner end thereof with a larger diameter portion; a cup secured to said axle spindle at said inner end thereof and defining a generally cylindrical recess essentially coaxial with said spindle, facing inwardly for receiving the end of a broken axle shaft on which said adaptor can be secured and having a diameter essentially equal to the diameter of said larger diameter portion of said axle spindle; a bracing member having inner and outer ends and secured at said outer end thereof to said cup externally thereof to extend inwardly therefrom and generally parallel to said axle spindle; and a shackle on said bracing member toward said inner end thereof for securing said adaptor on an axle shaft with said axle spindle essentially coaxial with such an axle shaft.
Claim 3
Dependent Claim
139 words
An axle adaptor which comprises: an axle spindle having inner and outer ends; a cup secured to said axle spindle at said inner end thereof and defining a generally cylindrical recess essentially coaxial with said spindle and facing inwardly for receiving the end of a broken axle shaft on which said adaptor can be secured; a bracing member having inner and outer ends and secured at said outer end thereof to said cup externally thereof to extend inwardly therefrom and generally parallel to said axle spindle; a shackle on said bracing member toward said inner end thereof for securing said adaptor on an axle shaft with said axle spindle essentially coaxial with such an axle shaft; and clamping means operatively associated with said cup for releasable engagement with the end of a broken axle shaft received within said cup.
Claim 4
Dependent Claim
139 words
An axle adaptor which comprises: an axle spindle having inner and outer ends; a cup secured to said axle spindle at said inner end thereof and defining a generally cylindrical recess essentially coaxial with said spindle and facing inwardly for receiving the end of a broken axle shaft on which said adaptor can be secured; a bracing member having inner and outer ends and secured at said outer end thereof to said cup externally thereof to extend inwardly therefrom and generally parallel to said axle spindle; a shackle on said bracing member toward said inner end thereof for securing said adaptor on an axle shaft with said axle spindle essentially coaxial with such an axle shaft; and clamping means operatively associated with said cup for releasable engagement with the end of a broken axle shaft received within said cup.
Claim 5
Dependent Claim
44 words
An axle adaptor as claimed in claim 2 and in which said clamping means comprises at least two shaft clamping members extending generally radially through said cup in threaded engagement therewith for tightening onto the end of an axle shaft received within said cup.

An axle adaptor which comprises: an axle spindle having inner and outer ends; a cup secured to said axle spindle at said inner end thereof and defining a recess essentially coaxial with said spindle and facing inwardly for receiving the end of a broken axle shaft on which said adaptor can be secured; a bracing member having inner and outer ends and secured at said outer end thereof to said cup externally thereof to extend inwardly therefrom and generally parallel to said axle spindle; a shackle on said bracing member toward said inner end thereof for securing said adaptor on an axle shaft with said axle spindle essentially coaxial with such an axle shaft; and a spacing member on said bracing member toward said inner end thereof for maintaining said axle spindle essentially coaxial with an axle shaft on which said adaptor is mounted when a spring-retaining shackle is present about such an axle shaft generally terminally thereof.
Claim 7
Dependent Claim
158 words
An axle adaptor which comprises: an axle spindle having inner and outer ends; a cup secured to said axle spindle at said inner end thereof and defining a recess essentially coaxial with said spindle and facing inwardly for receiving the end of a broken axle shaft on which said adaptor can be secured; a bracing member having inner and outer ends and secured at said outer end thereof to said cup externally thereof to extend inwardly therefrom and generally parallel to said axle spindle; a shackle on said bracing member toward said inner end thereof for securing said adaptor on an axle shaft with said axle spindle essentially coaxial with such an axle shaft; and a spacing member on said bracing member toward said inner end thereof for maintaining said axle spindle essentially coaxial with an axle shaft on which said adaptor is mounted when a spring-retaining shackle is present about such an axle shaft generally terminally thereof.
Claim 8
Dependent Claim
129 words
An axle adaptor which comprises: an axle spindle having inner and outer ends; a cup secured to said axle spindle at said inner end thereof and defining a recess essentially coaxial with said spindle and facing inwardly for receiving the end of a broken axle shaft on which said adaptor can be secured; a bracing member comprising an angle member having mutually angularly disposed and elongated first and second flanges, having inner and outer ends and secured at said outer end thereof to said cup externally thereof to extend inwardly therefrom and generally parallel to said axle spindle; and a shackle on said bracing member toward said inner end thereof for securing said adaptor on an axle shaft with said axle spindle essentially coaxial with such an axle shaft.
Claim 9
Dependent Claim
129 words
An axle adaptor which comprises: an axle spindle having inner and outer ends; a cup secured to said axle spindle at said inner end thereof and defining a recess essentially coaxial with said spindle and facing inwardly for receiving the end of a broken axle shaft on which said adaptor can be secured; a bracing member comprising an angle member having mutually angularly disposed and elongated first and second flanges, having inner and outer ends and secured at said outer end thereof to said cup externally thereof to extend inwardly therefrom and generally parallel to said axle spindle; and a shackle on said bracing member toward said inner end thereof for securing said adaptor on an axle shaft with said axle spindle essentially coaxial with such an axle shaft.
Claim 10
Dependent Claim
