Stephen A. Youngers - Clearwater KS

Assignee:

J. I. Case Company - Racine WI

International Classification:

E02F 506

US Classification:

37 86

Abstract:

A drive train assembly is provided for the digging chain drive sprocket and spoil dispersing auger of a hydrostatically operated trenching machine. The drive assembly is totally enclosed and includes a hydraulic motor, a rotatable drive sprocket-hub subassembly, a planetary gearbox, and a boom lift casting. The planetary gearbox and hydraulic motor are mounted on opposite ends of the boom lift casting, and they are drivingly interconnected by a drive shaft that passes through the casting. The planetary gearbox includes a housing for rotatably mounting the spoil dispersing auger such that the gearbox housing and auger act as a heat sink to dissipate heat generated by the driven gears within the gearbox. The digging chain drive sprocket subassembly is rotatably mounted on the boom lift casting adjacent the planetary gearbox, and it is connected to the gearbox whereby the digging chain drive sprocket and auger are driven in unison by the hydraulic motor.

International Classification:

B60D 100

US Classification:

280494

Abstract:

An articulated joint for an articulated vehicle. Upper and lower pivotal connections, each employing a ball and socket, allow pivoting of two vehicle sections about a vertical axis. The ball of the lower joint is attached to one section while the socket is attached to the other section of the vehicle. The socket and ball of the upper joint are attached to a support member free to move along a shaft in a transverse direction between two stops. The ball of the upper joint is free to move along a vertical shaft joined to the other section of the vehicle. The transverse shaft provides a bearing surface to transmit loads between the two vehicle sections. Seals along the support member prevent entrainment of dirt along the shaft and bearing. The stops are part of the structure attaching the transverse shaft to the vehicle.

International Classification:

E02F 506
E02F 514

US Classification:

37355

Abstract:

A boom assembly including a boom with laterally spaced side walls and adapted to have a digging chain and tooth assembly rotatable thereabout. A boom end idler assembly is arranged between the side walls at the free end of the boom for rotatably supporting the digging chain and tooth assembly. The boom end idler assembly includes a boom end idler rotationally supported by an anti-friction bearing. Axially aligned members pass through aligned apertures in the side walls of the boom and at least partially within the inner race of the bearing for defining the rotational axis of the boom end idler and for clamping the side walls of the boom to each other to minimize clearances between the boom and the boom end idler. Seals are provided to close the clearances proximate the bearing and inhibit foreign debris from contaminating the anti-friction bearing.

International Classification:

E21C 2530
E02F 506

US Classification:

299 82

Abstract:

A universal digging boom assembly is disclosed for attaching either a conventional type digging chain or a rock type digging chain for trenching operations. The boom assembly includes a box-like core section having upper and lower stiffening strips wherein each stiffening strip includes a plurality of embossments along its longitudinal extent. These embossments form mounting portions between the stiffening strips and the core section so that sprocket assemblies or channels may be attached to the boom assembly depending on the type digging chain being used. The digging boom also includes an attachment portion which permits the boom to be mounted on the trencher for both center and offset trenching operations. Other features include the sprocket assemblies and a rock chain channel which provide additional ease in the utilization of the various types of digging chains on the boom assembly.

International Classification:

G05G 1100

US Classification:

74480R

Abstract:

An improved control assembly is disclosed which is particularly suited for embodiment as a so-called mono stick control for a material handling implement. The control assembly includes a lever support member adapted to be pivotally mounted on an associated implement, and which carries a first control lever adapted to pivot with respect to the support member about a first pivot axis. The support member further carries a second control lever which is adapted for pivotal movement about a second axis parallel to and spaced from the first axis. Notably, the second control lever is operatively interconnected with the first control lever such that relatively large angular movement of the second lever results in a relatively lesser angular movement of the first control lever, with the second lever then acting to prevent movement of the first lever back into its neutral position. By this arrangement, a device operatively connected for control with the first lever can be controlled at two rates, thus permitting normal control by manipulation of the first lever, and relatively fine control by manipulation of the second lever.

International Classification:

E02F 381

US Classification:

414723

Abstract:

A coupling assembly for releasably securing an implement to a work vehicle. The coupling system includes top wedges which are engaged in wedge-shaped sockets, and tapered lower hooks that apply a continuous force to a pin or cylindrical rod which operates to tightly engage the wedges in the wedge-shaped sockets, thereby preventing movement and resultant wear between the engaging portions of the coupling assembly and having the capability of handling heavy, high load inducing attachments as well as existing attachments.

International Classification:

E02F 300

US Classification:

4033224

Abstract:

A coupling device is provided for interconnecting an attachment tool to the loader arm of the skid steer. The coupling device includes handles which are pivotable between unlocking and locking positions. The handles control coupling pins which diverge from each other and which move between a retracted position and an extended position to capture the attachment tool on the coupling device.
