Abstract
Abstract This rotary loader and side coupling system for transfer of semitrailers or containers has a vertical pivot post with one or more load handling lobes or turntables each mounted on a horizontal flat lobe on an end of a frame or arm which is hinged to a slip collar on the post and supported and propelled on wheels on a concentric cam track to revolve thereabout and lift and lower on slopes in the cam track to transfer a load on the lobe or turntable. The turntable is fronted with a bumper or face sloped or rounded or disc wheel to engage between pedestals or locators or into openings on a vehicle under the load. The turntable has two depending fingers spaced on opposite sides of the table's pivot for engaging the side of a vehicle or curb to turn the table to align with the vehicle or driveway for transfer. The turntable for trailers has pedestals spaced narrow at the front for reaching under the body rails between the wheels and landing gear and spaced wide along the inner side to support the side of the trailer facing the loader for stability for transferring a semi-trailer between a railway car and a station platform car, driveway or tractor. The lobe or turntable can serve as a coupler or preferably the loader has a coupling disc wheel supported under the lobe at constant coupling height while the turntable and/or lobe are lifted or lowered. Vehicles for coupling with the loader preferably have depressed center platforms or sills between pedestals or low sides and rollers for the coupling disc and/or lobe with or without turntable to enter between. A depressed-center semitrailer is provided to couple with this loader to handle containers. A two-lobed loader is designed especially to handle railway car body sized containers.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
75 words
A rotary loader having a single vertical pivot about which the loader revolves and at least one load arm which rotates about said pivot, means for engaging said arm with a relatively moving vehicle, a turntable mounted opposite said pivot for engaging and supporting a load, and means for aligning said turntable parallel to said vehicle in register for transfer of said load to or from said vehicle when moving past said loader engaged therewith.
Claim 2
Dependent Claim
75 words
A rotary loader having a single vertical pivot about which the loader revolves and at least one load arm which rotates about said pivot, means for engaging said arm with a relatively moving vehicle, a turntable mounted opposite said pivot for engaging and supporting a load, and means for aligning said turntable parallel to said vehicle in register for transfer of said load to or from said vehicle when moving past said loader engaged therewith.
Claim 3
Dependent Claim
56 words
A loader as in claim 1, said means for aligning including two depending members secured to said turntable and spaced apart to engage at points along the vehicle fore and aft of the pivot axis of the turntable to align the turntable parallel over the vehicle for transfer of a load to or from the vehicle.
Claim 4
Dependent Claim
87 words
A loader as in claim 1, said turntable having a front face and ends, the front face being peaked out from substantially the midpoint of said face to the ends to guide the loader to engage or disengage for coupling the ends into a transverse opening according to which side of center said face is hit on the vehicle during an attempt at coupling therewith to couple or deflect the loader away according to the angular position of rotation of the loader when engaged with the vehicle.
Claim 5
Dependent Claim
100 words
A loader as in claim 1, said vehicle being a railway car for at least one semitrailer, said turntable being longer than wide and having a lengthwise short or narrow outer or front pedestal means on top for extending along a portion of the length of a semitrailer and for extending under from either side to the opposite side of the semitrailer between supports of the semitrailer, and inner or rear pedestal means along parallel the semitrailer for supporting the side of the semitrailer facing the loader to provide a stable support for the semitrailer during transfer on the loader.
Claim 6
Dependent Claim
43 words
A loader as in claim 4, said pedestals being of a height and spaced to engage opposite side edges along the bottom of the semitrailer, so said loader can reach under the semitrailer to align the pedestals and lift the trailer from below.
Claim 7
Dependent Claim
34 words
A loader as in claim 1, said turntable having a front bumper peaked out at its middle and sloped back therefrom forming an inside angle of about 140 degrees or less between the slopes.
Claim 8
Dependent Claim
32 words
A loader as in claim 6 and a substantially horizontal disc wheel mounted to extend out slightly from the bumper at the peak to shift the loader if the wheel is engaged.
Claim 9
Dependent Claim
31 words
A loader as in claim 1, said arm being cushioned to extend in on itself when said turntable is engaged for transfer to align across a chord of the transfer are.
Claim 10
Dependent Claim
63 words
A loader as in claim 1, said loader having a coupling arm under said load arm, said means for engaging being a coupling disc supported by said coupling arm under said turntable to roll into a close fitting opening in the vehicle to couple it to rotate to align and transfer a load with relative tangential movement between the loader and said vehicle.
Claim 11
Dependent Claim
32 words
A loader as in claim 9, a coupling support track concentric about said pivot, and wheel means supporting said coupling arm to run on said coupling track at a height for coupling.
Claim 12
Dependent Claim
40 words
A loader as in claim 9 and a vehicle having low sides for said coupling disc to roll against and an opening for said coupling disc to key into to couple the loader to the vehicle for moving transfer therewith.
Claim 13
Dependent Claim
45 words
A loader as in claim 1, said arm being a frame having two members extending substantially radially out from said pivot with a circular said turntable on the outer end of each, each said turntable being for supporting an end of a load for transfer.
Claim 14
Dependent Claim
63 words
A loader as in claim 12, said members having outer ends parallel a line bisecting the angle between the pivot and the turntable pivot axii, said turntables being mounted to telescope in on said arms, means resiliently extending said turntables out on said arms, and alignment means on each said turntable to telescope the turntable to follow a chord through the transfer arc.
Claim 15
Dependent Claim
47 words
A loader as in claim 1 and a vehicle which has a chassis and a demountable body and at least one opening having vertical sides transverse through the body and chassis for said loader to engage in to register, couple, and lift the body from the chassis.
Claim 16
