Abstract
Abstract A mounting frame for resiliently supporting a railway vehicle motor-compressor unit on the vehicle, said mounting frame including a torque tube member to which the motor-compressor unit is mountingly connected for dissipating torque pulsations generated by the reciprocating piston action of the compressor. Advantage may be taken of the tubular structure by employing several of the tubular members in transmitting compressed air from the high pressure outlet of the compressor to the aftercooler which is also carried by the support frame.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
The combination of a motor-compressor unit for a railway vehicle and a support frame for mounting said motor-compressor unit to the underframe of the vehicle, said support frame comprising: a. a pair of fixed parallel, spaced-apart end members for securing said support frame to the underframe of the vehicle; b. a torque member extending from one of said end members to the other with its opposite ends rigidly secured to the end members, respectively, said torque member possessing limited, resilient, angular flexibility about its longitudinal axis; and c. a suspension member rigidly secured at a point intermediate its opposite ends to said torque member intermediate the ends thereof and in transverse relation thereto, d. said motor-compressor unit being resiliently supported by said opposite ends of said suspension member via which vibrations of said motor-compressor unit are transmitted to said torque member and dissipated thereby.
Claim 2
Dependent Claim
144 words
The combination of a motor-compressor unit for a railway vehicle and a support frame for mounting said motor-compressor unit to the underframe of the vehicle, said support frame comprising: a. a pair of fixed parallel, spaced-apart end members for securing said support frame to the underframe of the vehicle; b. a torque member extending from one of said end members to the other with its opposite ends rigidly secured to the end members, respectively, said torque member possessing limited, resilient, angular flexibility about its longitudinal axis; and c. a suspension member rigidly secured at a point intermediate its opposite ends to said torque member intermediate the ends thereof and in transverse relation thereto, d. said motor-compressor unit being resiliently supported by said opposite ends of said suspension member via which vibrations of said motor-compressor unit are transmitted to said torque member and dissipated thereby.
Claim 3
Dependent Claim
23 words
The combination, as set forth in claim 1, wherein said parallel members, said torque member, and said suspension member are of tubular structure.
Claim 4
Dependent Claim
53 words
The combination, as set forth in claim 1, wherein said suspension member is provided with suspension brackets disposed on each of the opposite ends thereof, and said motor-compressor unit is provided with a pair of side brackets disposed on diametrally opposite sides thereof in complementary relation and connectible to said suspension brackets, respectively.
Claim 5
Dependent Claim
44 words
The combination, as set forth in claim 3, wherein said suspension brackets and said side brackets provide a pair of weight support points lying within a plane transverse to and located substantially intermediate the opposite ends of the longitudinal axis of said motor-compressor unit.
Claim 6
Dependent Claim
23 words
The combination, as set forth in claim 3, further characterized by respective resilient elements interposed between said suspension brackets and said side brackets.
Claim 7
Dependent Claim
67 words
The combination, as set forth in claim 3, wherein said motor-compressor unit comprises an air compressor axially aligned with and operably connected to a driving motor therefor, and further characterized by an end bracket secured to said compressor and to one of said end members adjacent said compressor for providing a third weight support point, and a resilient element interposed between said end bracket and said compressor.
Claim 8
Dependent Claim
63 words
The combination, as set forth in claim 6, further characterized by an aftercooler secured to and supported by the other of said end members opposite said one of said end members, said end members also being of tubular construction and said air compressor having a high pressure outlet connected via said torque member and said other of said end members to said aftercooler.
