Patent number: 4451223Abstract: An improved corner finishing tool for applying mastic along a wall joint and having a container that defines a cavity open in two convergent and substantially perpendicular planes, said cavity being bordered by surfaces that converge peripherally of said cavity, said container means comprising a pair of rigid retainer plates joined together by a pair of spring loaded hinges or fasteners and biased to a position of resilient flex. A pair of lever arms pivotally secured to an edge portion of the retainer plates and pivotally joined together at one end are acted upon by leaf springs which engage the lever arms at selected positions relative to the pivotal connection for adjusting the resilient flex between the pair of retainer plates. Mastic material is fed into the cavity through a socket bracket that is mounted to one of the retainer plates to which there is also mounted an alignment wheel.Type: GrantFiled: July 28, 1982Date of Patent: May 29, 1984Assignee: Bliss & Laughlin Industries, Inc.Inventors: Morris F.

Patent number: 4417509Abstract: 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.Type: GrantFiled: August 6, 1981Date of Patent: November 29, 1983Assignee: Bliss & Laughlin Industries IncorporatedInventors: Christopher J. Deibel, Edward W. Massey

Patent number: 4348970Abstract: 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.Type: GrantFiled: April 1, 1980Date of Patent: September 14, 1982Assignee: Bliss & Laughlin Industries, IncorporatedInventors: Robert J. Robinson, David B. Johnson, Verdell H. Schroeder

Patent number: 4315613Abstract: A spindle assembly for a chair or the like includes an outer tube tapered to fit in a chair base, an inner tube having an upper end tapered to fit the chair control, and a bushing near the upper end of the outer tube to guidingly receive the inner tube therein. A screw is provided in the assembly and threadedly engaged with the inner tube, with means to prevent the screw from rotating in the absence of any axial external load on the assembly, whereby rotation of the inner tube with respect to the outer tube will cause a change of overall length of the assembly, to provide a height adjustment for a chair assembly secured thereto. Spring means employed in the assembly resiliently support the seat under a seating load and also accommodate disengagement of a rotational lock to permit swiveling of the seat with respect to the base without any change of overall height.Type: GrantFiled: November 1, 1979Date of Patent: February 16, 1982Assignee: Bliss & LaughlinInventors: Robert H. Godwin, Herbert E. Collignon

Patent number: 4266650Abstract: 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.Type: GrantFiled: November 26, 1979Date of Patent: May 12, 1981Assignee: Bliss & Laughlin Industries IncorporatedInventors: Ravin J. Patel, John Petro

Patent number: 4205413Abstract: A caster assembly is provided with a housing readily mountable into rectangular, square or round tubing and securable therein. A lever operable in a horizontal plane about the swivel axis is pivotable from a first position for free swiveling and rolling of the caster, to a second position for swivel locking in the trailing position, to a third position for swivel and wheel locking. It is readily attached to a centralized control handle on a bed or other object to be supported by the caster.Type: GrantFiled: January 10, 1979Date of Patent: June 3, 1980Assignee: Bliss & Laughlin Industries, Inc.Inventors: Herbert E.
