Abstract: A receptacle which may be tiered or stacked with other like receptacles and adapted to be nested when empty. Each receptacle in the tier or stack is intended to hold food products that are to be placed in a smoke house for cooking with the weight of each receptacle being supported by the product in the next lower receptacle in the stack and thus serving as a press to compress the product in said lower receptacle until such time as the product shrinks through the cooking process to a predetermined height. When the product is reduced to this predetermined height, each receptacle seats upon and rests upon the next lower receptacle in the stack to prevent further transmission of the product load and thus stops the pressing action at the predetermined height. Each receptacle is of unique design whereby it may be used to accommodate two alternate heights of smoked food product.

Abstract: A container adapted to nest and tier with like containers, with the container having a bottom wall and side walls extending upwardly from the bottom wall and terminating in a top edge extending around the container, and with there being provided tiering means projecting laterally of the ends of the container for tiering the container on the top edge of a like container with at least a portion of the ends of the container being open, and with one container being adapted to be entered into the first container in a tilted position so that the tiering means on the entering container passes through one of the open ends and beneath the overlying upper edge of the receiving container, and then the entering container is moved generally vertically downwardly into nested relation into the receiving container.

Abstract: A portable bag-closing sewing machine is provided with a self-oiling system which includes an oil reservoir connected to the machine and oil-delivery means to direct oil from the reservoir into the inner chambers of the machine where oil is distributed by gravity flow, capillary action and movement of machine components, the oil moving along through the machine components and through a series of channels, troughs, and reservoirs within the housing to distribute oil throughout the machine. During operation, the rotating and reciprocating machine parts fling oil outwardly within the chambers to directly oil machine assemblies and to create a fine mist of oil throughout the chambers so as to further lubricate machine components. Also disclosed is an improved and self-lubricating feed dog assembly and thread chain cutting device.

Abstract: Two longitudinally extending conveyors are connected by a plurality of novel hinge structures for movement between a first position with the two conveyors substantially in line, and a second position with one of the conveyors folded parallel to and on top of the other conveyor. One conveyor called a skate conveyor is referred to as the basic conveyor, while the other shorter conveyor is commonly called a stick conveyor and is herein referred to as the extension conveyor. Each hinge structure comprises a flat coupling hinge leaf generally triangular in shape and having acute apexes respectively one at each end. Each of the hinge structures includes a control link and pivotal connections respectively connected to the basic and extension conveyors, while a control link has a pivotal connection at one end with the hinge leaf near the obtuse apex at one end and is connected to the extension conveyor at its other end.

Abstract: An adjustable gas cylinder control comprising the combination of a single tube defining a single cylinder bore, a single piston slidable in the tube and dividing the tube into a first and a second compartment, a first and a second end plug adapted to sealably fit within the ends of the tube, a single spindle or rod fixedly mounted to the piston and reciprocable in the tube, gas inlet means for charging the sealed first compartment of the tube with gas, and valve means mounted in the piston and spindle for allowing gas flow between the first and second compartments of the tube thereby adjusting the position of the piston in the tube. The tube itself is made of rolled welded sheet metal with its ends having a simple cold formed impression holding the first and second end plugs. Also provided is actuating means including a lever connected to the spindle for actuating the valve means thereby allowing gas flow between the compartments of the tube.

Abstract: A chair tilting control having a bracket connectable to a seat and a bracket connectable to a base, the base bracket being entirely within the seat connector bracket and having a pair of elongated flat spring bars urging the seat connector bracket against the base connector bracket to the no-tilt condition, and a manually operable spring adjustment screw or lever driving a cam follower to increase or decrease the non-tilting action of the spring.

Abstract: A caster assembly has a brake shoe member including a wheel tread contacting shoe, and a foot operable brake applying and release lever, the shoe member being guided horizontally, both longitudinally and laterally adjacent the wheel contacting shoe for positive shoe action in response to operation of the lever.
