Abstract: A hydraulic jack comprises a base having a vertically disposed cylindrical member attached thereto. A cylindrical movable member is mounted on the fixed member and is vertically movable relative thereto. The base is provided with passages therethrough which are connected in communicating relation to a source of fluid under pressure, such as a reservoir and pump. The fixed and movable members define a pair of variable chambers, each of which is connected in communicating relation with one of the passages by a restricted orifice to reduce the flow of fluid to and from the chambers. When one of the chambers is pressurized, the movable member is raised and will support a load engaged thereby. When the other chamber is pressurized, the movable member is lowered. Fluid in the chambers is prevented from returning to the reservoir by valve elements. A valve actuator is operated by fluid pressure and selectively opens each passage to permit the return of fluid to the reservoir.

The mattress sections in the unfolded condition serve as a full mattress, and when in the folded condition constitute part of the sofa.

Abstract: A fireplace insert comprises an inner housing and an outer housing spaced from each other. Thermostatically controlled fans circulate air between the inner and outer housing to cause the air to be efficiently heated before it is distributed into the area or room to be heated. Adjustable vents control the flow of combustion air, and a baffle minimizes the loss of heat through the flue.

Abstract: A combined pump and oil reservoir and oil delivery apparatus directs oil to the internal chambers of a portable sewing machine where oil is distributed by pump pressure, gravity flow, capillary action, wicking, misting and movement of machine components. Oil is pumped into a manifold leading to upper and lower main drive shaft bearings and to the needle driving assembly for subsequent dispersion during rotation and reciprocation of machine parts to fling such oil outwardly within the internal chambers to oil machinery both directly and by misting.

Abstract: A pneumatic system for harvesting combines which is operable for pneumatically transferring clean grain to the grain tank and for pneumatically conveying the tailings to the threshing cylinder. The pneumatic system includes a clean grain collection tube and a tailings collection tube, each of which is provided with an airlock device which permits grain or tailings to be metered into the pneumatic system while preventing air or grain from escaping therefrom.

Abstract: An outdoor article of furniture includes a base and an elongate bed-like support mounted on the base for rotation and limited tilting movement relative to the base. Power means are provided and rotate the support at a rate of two revolutions per hour so that a user lying on the support will obtain an even sun tan on that portion of the user's body exposed to the sun. When the support is in a tilted position, there will be a tendency to cause a user reclining thereon to roll over when the support is moved through a half rotation, which occurs after a 15-minute interval. Thus, the apparatus itself could urge the user to turn over periodically and thereby minimize the occurence of sunburns caused by overexposure of a portion of the user's body to the sun.

Abstract: A compound composite structure is a combination of plastics and other materials forming a structure usable in the fabrication of manufactured products or components. A compound composite structure is composed of a thermoplastic resin material bonded to, by mixture with, a composite reinforcing structure. The composite reinforcing structure consists of fibers imbedded in a thermoplastic resin material. The composite reinforcing structure may be formed by passing extruded plastic resin material through a die which imbeds fibers. The compound composite structure may be formed by mounting a preformed composite reinforcing structure in a molding die and by injecting thermoplastic resin material into the molding die.

Abstract: A flat file having a number of drawers is formed of a shell having a number of shelves therein for locating the various drawers of the flat file. The shelves are located by means of shelf support members formed of corrugated board having portions which are slotted and folded into place so as to locate the shelves.

Abstract: A differential for vehicles comprising a differential carrier directly supported within a housing on the inner ends of a pair of axle shafts. A ring gear is mounted on the carrier; and one of the axle tubes in which the axle shafts are rotatably supported positions the carrier within the housing and takes the ring gear thrust load imparted thereto by a pinion gear on a drive shaft.

Abstract: A tote carrier for printed circuit boards is formed of wire members with each side being formed of a plurality of parallel wire members. The two ends have slidably mounted thereon at least two card holding members which are parallel to each other, which members have slots therein for holding the boards in position. The tote is stackable in two directions for either storage or assembly.

Abstract: A shipping container for relay racks has a platform base with pallet skids beneath. Two end panels are hingedly attached to opposite ends of the platform and extend upwardly. The end panels are attached to the ends of the relay rack by means of toggle bolts. The hinged construction allows the device to be easily folded for return shipping and also provides substantial protection against forklift puncture.

Abstract: A shoulder skinning apparatus includes a skinning device comprised of a housing having a revolvable toothed roller mounted therein and a blade mounted thereon in close proximity to the toothed roller. The skinning device is suspended from a suspension device and power means permits vertical positioning of the skinning device to assure effective removal of the skin from the shoulder area of the hog carcass. The toothed roller and skinning blade are dimensioned whereby when the toothed roller is revolved by power means, the skin from the shoulder area of the hog carcass may be progressively removed in a single pass. A separate control handle controls the positioning and operation of the skinning device by a means of a unique cam arrangement.

Abstract: Apparatus for filling bags and providing completely controlled handling of bags from pickup through their movement to a bag closing station. A pair of elongated forming bars supported for up and down movement and traversing movement between a bag filling hopper and a laterally spaced bag closing station grip, flatten, and assist in forming gusseted bags after filling while the bags are still clamped on a filling spout, and thereafter controllably lower the filled bags to a conveyor and support the bags on the conveyor in traversing movement to a final bag closing station. A pair of gusset arm assemblies supported for lateral shifting movement on opposite sides of a filling spout each include a pair of gusset clamping fingers which are disposed inside of the mouth of a bag during filling. The clamping fingers are actuated in a predetermined sequence to hold and form the gusset pleats of the bag while permitting the bag to be opened over its full width during the filling operation.

Abstract: The weight of items carried by a fork lift truck may be measured by this fork lift scale. This fork lift scale consists of horizontally disposed load sensors connecting a crossbar frame to the crossbars of the fork lift truck. Forks are supported by the crossbar frame. Strain gages are mounted on the load sensors to sense the weight of items carried on the forks. The strain gages are mounted to sense vertical shear or bending in the load sensors. The strain gages are positioned on the load sensors and are electrically interconnected so that types of loading, other than vertical loading due to the weight of items placed on the forks, are rejected and not measured by this fork lift scale.

Abstract: An apparatus for removing the mid-section portion of the skin from the carcass of an animal, such as a hog, includes a revolvable drum mounted on a frame. A flap forming mechanism is mounted on the drum and is operable to form a skin flap and grip the same to hold the skin against the drum during the skinning operation. A skinning blade is mounted on the frame and positioned adjacent the drum to cut the skin from the torso. A skin hold-back mechanism is mounted on the frame and includes an arm having a blade which engages the drum to remove the skin from the drum. This hold-back device engages the drum and dislodges the skin from the toothroll cavity when the mid-section portion of the skin is completely removed from the animal. The frame is mounted on a shock absorbing device which absorbs vertical forces transmitted to the frame during the skinning operation.
