This invention relates to a mounting arrangement (10) for resiliently connecting an exhaust stack (12) to an exhaust pipe (14) and a frame (18) which eliminates the problems of vibration, noise transfer, joint failure, high exhaust temperatures, complexity, and inability to quickly assemble and disassemble. The mounting arrangement (10) has first and second spaced apart elastomeric devices (60,80) for resiliently connecting the exhaust stack (12) to the frame (18), a support bracket (98) and an exhaust pipe (14). The first elastomeric device (60) supports an open end of the exhaust pipe (14) in the exhaust stack (12) and on the frame (18) and the second elastomeric device (80) engages the support bracket (98) and which retains the first elastomeric device (60) in contact with the frame (18). A passage arrangement (74) passes cooling air flow past the first elastomeric device to cool the first elastomeric device (60) and the exhaust stack (12). Thus the problems of vibration, noise transfer, joint failure, high exhaust temperature, complexity and difficulty of assembly and disassembly are eliminated. The mounting arrangement (10) is particularly suited for connecting the exhaust stack (12) to the frame (18) and an overhead guard (116) of a lift truck (20).

Mounting arrangement for an exhaust system

Wheel brake arrangement

A transmission control for a motor vehicle includes a valve and a spool mounted in the valve biased to extend therefrom. A spool actuator member controls extension of the spool from the valve. A spool control member is connected to move in response to movement of an operator control. An adjustable engaging member on the spool control member moves a predetermined distance free of forced engagement with the spool actuator. Subsequently the engaging member engages and moves the spool actuating member.

Transmission control

A reciprocal control member for a transmission is pivotally connected to a rotatable sleeve for selectively placing the transmission in its neutral, forward or reverse modes of operation. A hand lever is connected to the sleeve to rotate it to place the transmission in a selected mode of operation and to simultaneously control the speed thereof. A foot pedal is adapted to be depressed to control the output speed of the transmission by overriding the first input control when the first input control is either in its forward or reverse position of operation. The foot pedal is connected to the sleeve by a pair of pin and slot connections for inducing rotation of the sleeve upon movement of the foot pedal in either direction.

Dual control system for transmissions

A rocker shaft is rotatably mounted and integral with a control valve of a hydrostatic transmission. The valve shaft may be rotated in an arc to either side of a neutral position. A housing is mounted to the control valve with rocker shaft projecting into the housing. A pair of levers are pivotally mounted on the rocker shaft in scissored relationship thereon and an actuating arm is rotatably mounted on the housing to engage camming surfaces defined on first ends of the levers. A drive member or dog is secured to the rocker shaft to engage between second ends of the levers whereby pivotal movments of the actuating arm will transmit pivotal movements of the levers to the rocker shaft to control mechanisms of the control valve. The second ends of the levers are biased towards each other into engagement with the drive member by a coil spring and a stop lug is secured on each of the levers to engage and pivot the other one of the levers in response to pivotal movements of the actuating arm. The stop lug is incorporated as a device to assure positive response of the valve shaft at a high speed reversal of an input shaft secured to the actuating arm.

Control mechanism for hydrostatic transmissions

Hydraulic brake and clutch apparatus includes a master cylinder for applying pressure to a brake past a sequence valve, such pressure also being applied to move another valve against a spring from a position wherein a pump applies fluid pressure to engage a transmission, to a position wherein fluid pressure is dumped from the transmission to provide disengagement thereof.
