Abstract: In a track laying vehicle (10) a track tensioning apparatus wherein a track engaging idler (20) wheel is mounted to a cross member (82) for adjustment to tension the track by a piston (68) and cylinder (62). The cross member (82) is in turn adjustably (106) mounted to opposing sides (26, 27) of the vehicle track frame. Acting in conjunction with the track tensioning apparatus an accumulator (130, 146) is provided and is in fluid communication with the piston (68) and cylinder (62). The accumulator (130, 146) exerts a backpressure upon the fluid so that the idler (20) may recoil in response to excessive tension or shock upon the track.

Abstract: A filled piston (10) has a tube (19) extending axially through the core (13) of filler material. The tube (19) provides the passage (23) through which hydraulic fluid passes to lubricate the bearing surfaces of components associated with the piston (10). This eliminates the problem of the hydraulic fluid eroding the filler material and thus the need for visual inspection of the passage through the piston.

Abstract: It is common practice to provide clamps for various hydraulic hoses that are utilized on vehicles, to keep them from contact with the adjacent frame structures or movable implements. In addition to providing an orderly appearance, damage to the hoses, which would occur through such contact, is eliminated. The clamping arrangements typically are rather unwieldy, requiring numerous components. Also, they are usually attached to various structural members of the vehicle, through some form of manufacturing process which is both costly and time consuming. The present invention provides a clamping arrangement (10, 10') for a plurality of first conduits (12, 12') that includes two essentially identical body portions (16, 16', 18, 18') that have a plurality of sockets (22, 22') defined therein and are engageable with each other about a second conduit (14, 14'). When engaged with each other, each of the body portions (16, 16', 18, 18') become substantially rigid and nonreleasably secure the first conduits (14, 14') to the second conduit (12, 12').

Abstract: In the operation of construction vehicles, it is often desirable to quickly change from one work implement to another for various types of work. In order to accomplish this, adapting brackets or extensive support structure is added to the support arm and operating linkage of the vehicle to mount a specifically design work implement. Such designs have been known to alter the function of the operating linkages to a point where the performance of the work implement is sacrificed both in operational force capabilities and capacity. The coupling apparatus (10) of the subject allows a plurality of work implements (12) to be quickly coupled to and uncoupled from a vehicle. The coupling apparatus (10) does so in a manner that maintains the operating geometry of conventional linkages and thereby maintains the appropriate operational forces needed for manipulation of the work implement (12) with very little reduction in capacity from that of a convention work implement (12).

Abstract: A corner tooth is useful, for example, on construction equipment buckets to protect the sidewalls from abrasive wear which normally results from continued contact with the ground. In order to protect the sidewall, others use elements secured directly to the sidewall or various forms of specialized teeth mounted on the corner. Many of these specialized teeth inhibit the tooth's ability to penetrate the ground. The present corner tooth (10/10") provides the protection for the sidewall (36/38) while still maintaining good strength and penetration. This is due to a single flat member (52) being oriented vertically with respect to the normal working position of the tooth and a single reinforcement rib (54) extending perpendicular to the flat member (52). Furthermore, since the tooth (10/10") is symmetrical about the second plane (50) and the rib (54) is located along the second plane (50) the tooth can be used on either corner. This eliminates the need to manufacture and stock an extra part of a different design. Furthermore, once the part is installed, it remains in the same location for its entire useful life thus eliminating down time to change the tooth from one corner to the other.

Abstract: A countershaft transmission (10) provides three forward speeds and three reverse speeds using an input shaft (12), an output shaft (14), an intermediate shaft (16), five rotating clutch assemblies (92, 94, 130, 136, 142) of the interleaved multiple plate and disc type, and eight gears (102, 110, 126, 122, 138, 144, 146, 132). The first speed clutch assembly (142) is mounted on the intermediate shaft (16), the second and third speed clutch assemblies (130, 136) are mounted on the output shaft (14), the remaining directional clutch assemblies (92, 94) are mounted on the input shaft (12), and the clutch assemblies are generally compactly grouped. Advantageously, no separate idler gear and associated shaft are required.

Abstract: Control valves having a valving element which is movable against an increasing biasing force for controlling fluid flow to and from an actuator are useful in construction vehicles to control a clutch and/or a brake. The increasing biasing force of the springs adds to the operator's fatigue. Some systems use pressure responsive surfaces on the spool to offset the added spring forces but these require a source of pressure that can be varied relative to spool position. The present lever assembly (22) provides an input shaft (78) having a lever (80) secured thereto with a cam surface (84) defined on the lever (80) and a force transmitting mechanism (106) adapted to transmit a variable force to a control spool (44/46) in response to the position of the lever (80). The force transmitting mechanism (106) in combination with a profile (86) on the cam surface (84) effectively reduces the required input force needed to move the spool (44/46) against an increasing biasing force resisting movement of the spool (44/46) thus reducing operator fatigue.

Abstract: A scraper (10) has a bowl (12) and a floor (14) and is constructed to receive an auger (18). Material moving up the cutting edge (16) and pushing against a diverter requires greater force to load the scraper. Apparatus (24) having a substantially smooth inclined surfaces are provided for moving material into the bowl (12) past a compaction zone (52) onto the spiral flight (21) of an auger (18) and also block incoming material from the compaction zone (52) and lodging between the leading edge (23) of the auger (18) and the bowl floor (14).

Abstract: Planetary gear mechanisms are useful in distributor fuel injection pumps to couple a distributor rotor with a drive shaft in order to rotate the distributor rotor at a preselected output angular speed which is proportional to and less than a preselected input angular speed of the drive shaft. Previously disclosed planetary gear coupling arrangements are typically rather bulky and merely provide an angular speed reduction function. In contrast, the subject thrust and planetary gear coupling (10) provides a relatively more compact arrangement for angular speed reduction and also includes a stationary dual-thrust plate (352) which controls axial end play of both the drive shaft (38) and the distributor rotor (348). The coupling (10) further includes a relatively inexpensive and easy to assemble planet gear and carrier assembly (424, 428, 432, 436, 440, 444, 448) which during operation rotatively drives the distributor rotor at the same output angular speed and which can also bear against the dual-thrust plate to act as a running thrust member.

Abstract: An elastomeric belt laying vehicle (10) for transmitting greater tractive effort to the earth as compared to comparably powered wheel vehicles and being operable at high speed on improved road surfaces without inflicting damage thereto. A pair of the wheels (24, 26) are arranged on each lateral side (28, 30) of the vehicle's chassis (12) for support thereof. An inextensible, endless belt (36) is highly tensioned throughout its length, is entrained about each pair of wheels (24, 26) and is frictionally, drivingly coupled to at least one wheel (24) of each pair. The structure of the belt (36), structure of the wheels (24, 26) and cooperating components (46, 48, 82) thereof ensure engagement therebetween, provides long service with minimum maintenance thereof, and supplies the necessary frictional couple to effectively transmit driving torque from the wheels (24) to the belt (36).
