The device is provided with hydraulic means for retaining the control lever in at least one of the said extreme operative positions.

Abstract: A vehicle hydraulic system wherein there is provided a primary pump coupled to a steering control valve through which steering of the vehicle is effected. A main priority valve is used to meter the flow of pressurized hydraulic fluid from the primary pump to either the steering control valve or an implement valve which is utilized to effect operation of auxiliary equipment, in accordance with the priority demands of the steering system. An auxiliary ground-drive pump provides a source of pressurized hydraulic fluid at all times the vehicle is in motion and is coupled to the steering control valve to provide a source of pressurized fluid when necessary or circulates the pressurized fluid to sump. The application of the output from the ground-drive pump is controlled by a secondary priority valve coupled to the output from the ground-drive pump to direct the output to the steering control valve or to sump.

Abstract: The disclosed device comprises a pair of hingedly connected pocket formations receiving data cards which are derived by folding and connecting a plurality of initially integral panels, the panels being formed by cutting and scoring a blank of paperboard of relatively light gauge, and thereafter being folded and secured so as to provide the hingedly connected pocket formations in each of which an end panel of the blank forming the data card is confined and is accessible through an open end so as to enable it to be torn loose and to be moved to different positions in the pocket thereby enabling data imprinted thereon to be viewed through window openings in a wall forming panel on which related data may be imprinted.

Abstract: A lightweight device for obtaining improved traction efficiency of rubber tired vehicles without adding ballast weight. The device has resilient traction intensifying means secured to a driving tire, including auxiliary means for utilizing stronger sub-surface soil, providing higher drawbar pull at a higher rate of travel speed; and means for convenient attachment and removal.

Abstract: A wrap around carrier package for returnable beverage bottles is disclosed which is formed by wrapping about an assembly of the bottles which are arranged in double row and transversely paired relation, a cut and scored blank of foldable sheet material, so as to form a tubular configuration, having bottle retention means, and securing the end panels of the blank by interengaging locking and latching elements thereon with cooperating elements on the bottom margin of a center partition forming member which is disposed between the rows of bottles and which has a handle portion at its top margin, the handle portion being rendered accessible by tearing out a substantial portion of the top wall panel of the package so as to release the bottles for removal through the resulting top opening and permit return of the empty bottles, thereby converting the carrier to an open-top basket style carrier.

Abstract: A pallet is disclosed which is particularly adapted for supporting in stacked relation thereon groups of articles so as to facilitate fork lift handling and which is fabricated by cutting, scoring and folding a generally rectangular sheet of foldable material, such as, paperboard, or the like, so as to provide a supporting platform with a center portion depressed, or recessed, and forming an upwardly opening pocket, into which, one or more of the articles may be placed, and having a peripheral sidewall extending below the bottom face of the platform which sidewall is spaced from the perimeter of the platform a sufficient distance to provide clearance for the entry of the fork lift arms when the pocket formation is resting on a surface on which the fork lift is operable.

Abstract: A safety or lock pin operatively engaged in a portion of the vehicle adjacent to the vehicle lift arm and coupled to the vehicle frame. The safety or lock pin is inserted into the portion associated with the vehicle frame so that the lift arm is prevented from lowering past the safety pin. A retaining pin is engageable in a bracket positioned adjacent the opening for the safety pin to retain the safety pin in its operative position. When in an inoperative position the safety pin is carried in a bracket secured to the vehicle frame and having an aperture through which the retainer pin passes to insure that the safety pin does not become lost during vehicle operation. Suitable safety chains couple the retaining pin to the safety pin, and the safety pin to the vehicle frame to insure that neither pin becomes separated or lost.

Abstract: Vehicle traction devices for passenger cars and alike including a flexible belt-like traction mat with transverse corrugations on one side and substantially smooth on the other side. In one embodiment, one end of the mat is secured to anchoring means including a flexible anchoring pad and ground gripping element. In another embodiment, the mat is secured to a bridge having cleats for anchoring the device to the ground.In use, the traction mat is first arranged to form a loop relative to the anchoring means. With its corrugations facing a tire and its smooth side facing the ground, the traction mat will easily be drawn under a spinning wheel until that end of it, which is secured to the anchoring means, becomes choked by the anchoring means. The tractive effort then developed causes the anchoring means to become wedged and thus assuring its fixed position, whereby the traction mat is prevented from being propelled away by the driven wheel.

Abstract: Accelerator/decelerator pedal and systems having a foot-operated pedal assembly to accelerate or decelerate vehicle engine speed and/or output on a temporary basis to override a hand lever set throttle position. The pedal and systems herein disclosed possess a double-acting spring linkage to absorb override movement of the foot pedal during such temporary acceleration or deceleration and to re-establish the original set hand throttle speed upon cessation of the override mode. An anti-feedback device prevents the throttle set position from being altered during acceleration or deceleration of engine speed and/or output.

Abstract: A mixed flow fan assembly including a rotating mounted impeller having a plurality of blades. An orifice member is mounted adjacent the tip of the blades to form an orifice area to receive air drawn in by an impeller in a first direction.
