Abstract: An earthmoving bucket (10) for use with various types of wheel and track-type earthworking and construction machines is constructed to provide great strength and rigidity while at the same time not being unduly bulky or heavy. The bucket (10) is further characterized by simplified manufacturability and cost advantages. Previous earthmoving buckets, which required considerable strength and durability, were quite heavy and bulky, with respect to bucket size, and required complicated, costly, and time-consuming assembly procedures. The earthmoving bucket (10) of the present invention utilizes a pair of unitary cast lift brackets (52, 54) which incorporates the pin bores (56) for the lift linkage, the rack-back stops (58), and the bucket dump stops (60).

Abstract: The present cooling system (21) provides a limited flow rate to clutches (26, 28) (for example in industrial vehicles) during disengagement and provides additional cooling flow to the clutches (26, 28) during partial engagement and controls the pressure level of the fluid from the source of cooling fluid (42) by operation of a valve mechanism (46) which is responsive to a control mechanism (110). Upon full engagement, the valve mechanism (46) automatically reduces the volume of cooling fluid to the clutches (26, 28) and simultaneously reduces the pressure level of the cooling flow from the source of cooling fluid (42). This cooling system provides the needed volume of cooling fluid during partial engagement of the clutches (26, 28) and also reduces the volume of cooling fluid during disengagement to reduce drag forces while further reducing the volume of cooling fluid during full engagement to conserve horsepower.

Abstract: A method and apparatus is provided for manufacturing a reinforced elastomeric hose. Other reinforced hoses are prepared in individual stations for particular parts of the reinforced hose consequently requiring large amounts of manufacturing floor space. Still other hoses that are made while utilizing small amounts of floor space do not provide a high strength braided reinforcement member. A reinforced hose (10) is produced by continuously braiding a tubular reinforcement member (16) on a mandrel (50), progressively removing the reinforcement member from the mandrel (50), and at approximately the same axial location extruding a liner (26) and cover (28) onto the reinforcement member (16) adjacent the mandrel (50). After leaving the extruders (33, 34), the formed hose (10) is pulled at a linear rate faster than the hose (10) is being produced in order to change the braid angle of the braided reinforcement member (16) to a predetermined smaller braid angle. As the hose (10) leaves the extruders (33, 34), it is pulled through a curing mechanism (30) to cure the hose (10) while the braid angle is at the predetermined angle. Upon release and cooling of the hose, the hose rebounds to an optimum braid angle of approximately 54o 44'. Th braided reinforcement member (16) provides the high strength characteristics while the extruding of the liner (26) and cover (28) at approximately the same axial location near the braiding mandrel (50) minimizes the manufacturing floor spaced and reduce cost.

Abstract: System for monitoring an engine operating parameter, such as oil pressure, which varies in proportion to engine speed, monitors the parameter relative to an upper and lower setpoint. Oil pressure is sensed by a transducer (122) and the sensed pressure is monitored by a pair of comparators (252, 266) which compare the sensed oil pressure with reference voltages corresponding to the upper and lower setpoints. The reference voltages may be selectively altered by a switch (124) in order to change the pressure setpoints. The outputs of the comparators (252, 266) control an annunciator (16) which indicates when the monitored pressure is below either of the setpoints. A circuit (75) is provided to inhibit operation of the annunciator (16) by the comparators (252) monitoring pressure relative to the uper setpoint when the engine's speed is below a predetermined value. The output of the comparator (266) monitoring pressure relative to the lower setpoint controls a service-hour meter (18) to provide an indication of the total elapsed time that the engine is running.

Abstract: A fluid seal device (10) has a plurality of non-contacting fluid seals located at the operative interface (16) between a stationary member (18) and a rotatable member (20) for preventing the leakage of a fluid from a fluid chamber (14). The first of the non-contacting seals (24) is a labyrinth seal (32) located adjacent the fluid chamber (14). The second non-contacting seal (40) is a spiral groove (42) located adjacent and in serial relation to the labyrinth seal (32). A third non-contacting seal (60) is a fluid slinger (62) which is located between the fluid chamber (14) and the labyrinth seal (32) for directing fluid (12) away from the path of operative interface (16). The fluid seal device (10) eliminates friction and increases the life expectancy thereof when used at the operative interface (16) between a stationary member (18) and a rotatable member (20) such as a crankshaft and block of an engine.

Abstract: A heat exchanger (10) having a plurality of longitudinally-extending tubes (16) disposed within a shell (12) includes an elastomeric end plate (18) and means (22) for compressing the elastomeric end plate (18) and expanding the plate in the longitudinal direction and internal vibration-damping baffle plates (28). The elastomeric end plate (18) is mounted under compression in only a direction transverse to the tubes (16) passing through the plate (18). The elastomeric end plate (18) is not restrained in a longitudinal direction with respect to the tubes (16) and as result of the transversely-applied compression force, the end plate (18) is expanded in the longitudinal direction. The vibration energy absorbing baffle plates (28) have a hardness less than that of the tubes (16). The heat exchanger (10) of the present invention is particularly useful for severe-duty cycle, vibration-prone vehicular applications.

Abstract: Les patins de chenille pouvant rouler sur une route utilisés dans des véhicules du type à chenille, tels qu'un tracteur agricole, comprennent chacun au moins une dent élastomère sur laquelle est attachée une plaque d'ancrage en acier. La fixation de la plaque d'ancrage sur un patin de chenille forme normalement des bords d'attache exposés qui sont soumis à des efforts élevés de traction ou à des défaillances pendant le fonctionnement du tracteur. En outre, de la terre et autres matériaux tendent à pénétrer dans les bords attachés, ce qui facilite les défaillances de la fixation. L'assemblage de dents (11) décrit dans la présente invention élimine ces problèmes grâce à une partie comprimée de lèvre (27) d'une dent élastomère (12) entre une nervure (24) solidaire du patin de chenille et chaque côté extérieur (28) d'une plaque d'ancrage (13). En outre, un joint statique (30) est formé entre la partie de lèvre (27) de la dent (12) et la nervure (24).

Abstract: Roadable track shoes employed on track-type vehicles, such as a tractor, include an elastomeric grouser having a steel anchor plate bonded thereto. Bolting of the plate on a track shoe would normally provide bonded edges on the outer edges of the anchor plate. The forced ingress of soil into these bonded edges during tractor operation could induce bond failure. The grouser assembly (11) of this invention overcomes this problem by providing a spacer (21) between a track shoe (10) and an anchor plate (13) to define a separation space(s) between remaining portions of the anchor plate (13) and the track shoe (10). An elastomeric grouser (12) is bonded to the anchor plate (13) and elastomeric material thereof fills the space(s).

Abstract: In the operator's station of many construction vehicles, there is a critical lack of space in which to mount the control levers (12) used to operate the vehicle. The use of mechanical linkages and motion translating devices between the control lever (12) and the actuator has required complicated mechanisms and excessive hardware for the mounting and positioning of the respectively connected components. The mounting apparatus (10) of this invention overcomes these problems by employing a detent mechanism (38) that functions as a rotational positioner between the control lever (12) and an actuating switch (60) assembly as well as an axial positioner used in the mounting of the respective components. The mounting apparatus (10) allows the control lever (12) and the actuating switch (60) to be mounted together for rotation about a single axis (X) to provide a very axially compact mechanism.
