What is disclosed is method and apparatus for alleviating the problem with cleaning of sluice boxes. The invention is characterized by continuous cleaning of an endless belt onto which the heavy metal concentrate is projected by a conventional sluice boxes, shaker screens and the like, and eliminating the down time of the apparatus for cleaning, as in the prior art. This down time is approximately fifty percent of the time.

Cleaning sluice boxes

An improvement in scrapper type vehicle, for handling junk cars and the like, having a frame mounted on wheels and having a prime mover powering the vehicle, characterized by a pair of beams having their inner ends pivotally attached to the frame at a pair of respective first points for pivotal movement about the first transverse, horizontal axis thereat; a lifting fork pivotally attached to the main beams at their respective outer ends at a pair of respective second points and having lift prongs adapted to load the junk cars onto a transport vehicle; elevating rams connected with the main beams and the frame for elevating the junk cars; and load fork tilting rams attached to the main frame at a pair of respective third points for pivotal movement about a second transverse, horizontal axis thereat. The lift fork tilting rams are attached to the lift fork at a pair of respective fourth points. The respective first and third points are disposed vertically with respect to each other in the same respective directions that the second and fourth points are disposed with respect to each other when the lift fork prongs are neutrally tilted, or substantially horizontal such that the lift fork can be moved from ground level to maximum height with the neutral tilt maintained by only raising the outer ends of the main beams.

Scrapper type vehicle

This specification discloses an off-road vehicle employing an improved hydrostatic drive system including engine driven variable displacement pumps having respective actuating members for varying displacement in two directions equivalent to forward and reverse directions, wheel motors at each wheel representing hydraulic actuating device operable by the fluid from the pump, hydraulic reservoir, serially interconnecting supply and return lines, and an improvement comprising one or more operator control members and a sensitivity control means for controlling the range of movement of the actuating member responsive to movement of the operating control member in a respective direction. Also disclosed is a preferred embodiment in which four wheel hydrostatic drive is employed with an option of converting the hydraulic fluid output that normally goes to one set of wheels such that all of the fluid goes to the other set of wheels for road speed operation. Also disclosed are the details of preferred structural embodiments.

Hydrostatic variable ratio control system

This specification discloses an off-road vehicle that both articulates and oscillates, thereby enabling achieving a highly maneuverable, more nearly level working platform from which attachments can be operated with utmost effectiveness. The vehicle is characterized by front and rear sections, each carried by two wheels and connected at an articulating steering joint with steering rams and steering means; and a mechanism on the front section for leveling the front section. The leveling mechanism includes a front frame member that supplies the main structural support for the front section and is pivotally connected with a front axle, with hydraulic rams disposed on either side of the pivotal connection and connected via control valve with a source of high pressure hydraulic fluid for attaining and holding a predetermined, or substantially level, position. In the preferred embodiments, a lock valve is interposed between the control valve and the hydraulic rams for providing a positive liquid lock to hold a predetermined position. Also disclosed are preferred embodiments.

Off-road vehicle that both oscillates and articulates

An improved method and combination facilitating interchanging attachments on an adaptable off-road vehicle characterized by, in addition to the usual vehicle and its controls, prime mover, power source, drive apparatus, steering apparatus and the like, a first portion of attachment apparatus carried by the vehicle including a plurality of mounting stations on respective front pair of elongate substantially horizontal tracks and front and rear pairs of vertical tracks; the tracks being spaced apart a first predetermined distance; each mounting station having a plurality of apertures that are laterally aligned for even mounting of the attachments; a plurality of attachments, each having respective second portion of attachment apparatus, each second portion including a pair of track engaging clevises laterally spaced apart the first predetermined distance and having a plurality of apertures adapted to align with the apertures at the mounting stations; a plurality of pins for inserting through the aligned apertures in the attachment apparatus and quick-connect fittings carried by the frame and by each attachment for a supplying operating power. Also set forth are preferred embodiments.

Adaptable combination of vehicle and attachments

This specification discloses an off-road type vehicle employing an improved hydrostatic drive system having a variable displacement pump having an actuating member for varying displacement in at least one direction, wheel motors representing actuatable devices operable by fluid from the pump, hydraulic reservoir, serially interconnecting supply and return lines and an improvement comprising an over control compensation that includes high pressure relief valves on the high pressure supply lines; a neutralizing means for moving the actuating member back toward its neutral position responsive to hydraulic pressure released by the relief valves, and a bleed-off means connected with the neutralizing means and adapted to bleed-off high pressure hydraulic fluid to allow restoring operation and a bleed-off return for returning the bleed-off hydraulic fluid to the reservoir. Also disclosed are preferred embodiments in which the actuating member includes a pair of pedals for forward and reverse controls with respective means preventing operation of more than one pedal at a time and pedal travel limit stop, as well as a preferred linkage for operator comfort.
