Abstract
Abstract A generally rectangular support framework is mounted for movement along a pair of fixed spaced parallel tracks. The framework comprises two interconnected portions each of which is of generally U-shaped configuration and includes a long and a short leg, the long leg of one of said framework portions being detachably connected with the short leg of the other of the framework portions. An elongated trolley support is mounted on said support framework for movement laterally with respect thereto. A trolley means is mounted for movement longitudinally along the trolley support.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
124 words
Trolley crane apparatus for use with a pair of spaced tracks and comprising a generally rectangular support framework, trolley means movably supported by said framework, said framework including two separate detachably connected portions, means for supporting said portions for movement along a pair of associated tracks, each of said portions of the framework being of generally U-shaped configuration and including a short leg and an opposite long leg which is substantially longer than said short leg so that said two separate portions of the framework can be swung into the confines of two spaced tracks while minimizing the lateral clearance required in the tracks to enable the portions of the framework to be swung into and out of operative position relative to the tracks.
Claim 2
Dependent Claim
124 words
Trolley crane apparatus for use with a pair of spaced tracks and comprising a generally rectangular support framework, trolley means movably supported by said framework, said framework including two separate detachably connected portions, means for supporting said portions for movement along a pair of associated tracks, each of said portions of the framework being of generally U-shaped configuration and including a short leg and an opposite long leg which is substantially longer than said short leg so that said two separate portions of the framework can be swung into the confines of two spaced tracks while minimizing the lateral clearance required in the tracks to enable the portions of the framework to be swung into and out of operative position relative to the tracks.
Claim 3
Dependent Claim
20 words
Apparatus as defined in claim 1 including quick connect and disconnect means for detachably interconnecting said portions of the framework.
Claim 4
Dependent Claim
30 words
Apparatus as defined in claim 1 wherein each of said frame portions includes a transverse I-Beam member interconnected at opposite ends thereof with angle members extending longitudinally of the apparatus.
Claim 5
Dependent Claim
33 words
Apparatus as defined in claim 3 wherein each of said detachably connected portions of the framework includes a cross brace member connected between said transverse I-Beam member and one of said angle members.
Claim 6
Dependent Claim
26 words
Apparatus as defined in claim 1 including stop lug means carried by said support framework for limiting movement of the framework with respect to associated tracks.
Claim 7
Dependent Claim
23 words
Apparatus as defined in claim 1 wherein said framework includes laterally extending guide means for guiding movement of the framework along associated tracks.
Claim 8
Dependent Claim
36 words
Apparatus as defined in claim 1 including a trolley support extending longitudinally of the apparatus and being supported by said framework for movement relative thereto, said trolley means being supported for movement along said trolley support.
Claim 9
Dependent Claim
43 words
Apparatus as defined in claim 7 wherein said trolley support includes an I-Beam member, antifriction means carried by said I-Beam and movable along parts of each of said two portions of the framework whereby the trolley support is movable laterally of the framework.
Claim 10
Dependent Claim
29 words
Apparatus as defined in claim 7 including stop means at opposite ends of said trolley support for limiting movement of said trolley means with respect to said trolley support.
Claim 11
Dependent Claim
35 words
Apparatus as defined in claim 7 including trolley lock means on said trolley support for cooperating with said trolley means to lock the trolley means in a predetermined position with respect to said trolley support.
Claim 12
Dependent Claim
18 words
Apparatus as defined in claim 10 wherein said trolley lock means is swingably supported on said trolley support.
Claim 13
Dependent Claim
32 words
Apparatus as defined in claim 7 wherein said trolley means is provided with antifriction means engaging said trolley support for providing free movement of said trolley means longitudinally along said trolley support.
Claim 14
Dependent Claim
90 words
Apparatus as defined in claim 1 wherein each of said detachably connected portions of said support framework is of generally U-shaped configuration, each of said portions having a long leg and a short leg, the long leg of one of said portions being interconnected with the short leg of the other of said portions, a trolley support supported by said framework for movement laterally with respect thereto, said trolley support extending longitudinally of the apparatus, and trolley means supported by said trolley support and movable therealong longitudinally of the apparatus.
