Abstract: A circular knitting machine having a program or pattern drum coaxial and underlying the needle cylinder. The pattern drum is advanced intermittently and selectively by pawls engaging ratchet wheels of different pitch on the drum, with the pawls driven with different strokes though shafts parallel with the cylinder axis and oscillated by followers riding on cams on the needle cylinder, the followers being selectively and independently displaceable by electro-mechanical units to produce intermittent operation of the pattern drum. Cams on the drum act through followers mounted on shafts coaxial with the cylinder axis to oscillate operating arms for controlling radial cams for needle and jack butt manipulation, for controlling an arm with an inclined surface for displacing the cylinder to adjust the length of the loop being knit, and for controlling other instrumentalities of the machine.

Abstract: A furniture angle brace that has a central bracing portion from which a pair of flat flanges extend angularly with two flat rectangular tabs projecting generally perpendicularly from each flange for assembly in a furniture joint to secure a leg and two side members together with the flat flanges flat against the side members and the tabs seated in slightly smaller cylindrical bores in the side members for receiving alignment with the tabs for indenting side edge-to-cylindrical surface seating of the tabs in the bores. The brace is secured to the side members and leg by screws that fix the brace flanges to the side members and by a screw or bolt that draws the central portion of the brace toward the leg and thereby secures the side members to the leg with the tab and bore connections providing proper configuration of the parts and rigidifying the completed joint.

Abstract: Method and means for transferring knit loops from single-hook needles on one cylinder to single-hook needles on the other cylinder of a double cylinder circular knitting machine. In the method and needles are displaced at an inclination outwardly of their cylinders to allow axial sliding of the opposing needles behind the inclined needles and into the loops held on the inclined needles; the inclined needles are then withdrawn to shed the hooks, which are then received on the hooks of the other needles. The means includes radial pins slidably carried in the cylinders for engagement and operation by stationary radial cams located within the cylinders, the pins extending through the cylinders and into engagement with the stems of the needles for radially displacing the needles outwardly to the inclined positions required by the described method.

Abstract: A method and apparatus for rapidly cooking food which includes pressing food directly against a very hot cooking surface with a liquid interface therebetween while the food is submerged in a heated cooking liquid, such as a water-base broth. The cooking surface is preferably formed with a plurality of dispersed dimples which collect and contain the liquid interface at the cooking surface when the food is pressed thereagainst. The apparatus includes two pans located at the extending ends of a connecting conduit with a perforated compression plate for pressing food against the bottom surface of each pan, and a burner is disposed beneath each pan. Controls are provided for alternately lowering the pans to positions immediately above these respective burners and to permit the cooking liquid to flow into the lowered pan, and for automatically energizing and de-energizing the burners when the pans are lowered and raised with respect thereto.

Abstract: An automatic sprinkler head of the type wherein a frangible bulb member is held in a frame between an adjustable retainer and a valve member normally seated in a bore provided in the frame and supplied with a fire extinguishing fluid. The valve member is of unitary construction, and is formed with an annular flat surface portion disposed in facing relation to a corresponding annular flat surface portion formed in the frame about its bore. A resilient ring element is disposed directly between the aforesaid facing surface portions to seal the bore and to provide a yieldable support for the valve member. The valve member has dimensions which permit it to be freely movable within the frame seat, and the ring element is maintained between the valve member and the frame seat by the structural formations thereof.

Abstract: Means for selectively positioning needles in a circular knitting machine wherein a radially movable needle positioning cam is insertable from an inoperative position out of the path of control butts of needles or jacks into fully inserted or partially inserted positions to selectively engage all the butts or only long butts. A needle raising cam is mounted in advance of the needle positioning cam with its advance end pivoted for positioning of the raising cam down out of the path of control butts, in a fully raised position engaging the control butts to raise them clear of the positioning cam during insertion of the positioning cam, or in an intermediate inclined position to raise the control butts for engagement with the positioning cam at an inclination that permits high speed operation. The raising cam is mounted on a shaft that is operated by a mechanism that is driven from a pattern drum mounted on the machine coaxial and underlying the needle cylinder.

Abstract: A lengthwise miter joint and boards for forming it have mating effective V-tongue and -groove portions in their miter faces for positive registered alignment of the joint while it is being permanently fastened as by gluing, nailing, etc. The tongue and groove portions are centered widthwise of their respective miter faces so that the same boards may be selectively assembled either in angular or aligned relation to each other. The effective included angles of the tongue and groove provide registered angular assembly of the joint with a single rectilinear motion of one board perpendicular to the flat sides of that board. The effective V-tongues and -grooves characteristically provide relatively strong shapes to both boards in a joint.
