Abstract: A cutting tool made of a material having a high red hardness for the continuous machining of metals and having a geometry determined by the change in measurements of a sample of the metal being machined when the sample is externally loaded to failure. The sample is subjected to a tensile load to produce the failure. Elongation and neck down are caused in the failure area according to the ductility of the metal. The effective cutting or rake angle of the cutting tool is established as a function of the elongation and neck down of the sample. The relief angles of the cutting tool geometry are determined to maintain a self-sharpening cutting edge under the abrasive characteristics of the workpiece material and erosion characterisitcs of the cutting tool material for given machining conditions.The effective rake angle of the cutting tool is also established as the minimum angle producing chips of maximum hardness during the machining operation.

Abstract: A tracklaying vehicle comprises first and second laterally spaced tracklaying units which are spaced apart in a travel direction from third and fourth tracklaying units which are spaced laterally from each other. A substructure which is supported on and located in between the tracklaying units includes a carrier shaft extending in the travel direction which provides a journal for rotatably mounting a cross beam which extends between one set of the tracklaying units, for example, the first and second tracklaying units. The other set of tracklaying units, the third and fourth one, are designed as steering units, and they are mounted on individual arms which are pivotally mounted on vertical pivots of the substructure and which are connected to steering devices for pivoting them about the rotatable mountings on each side of the substructure in order to shift the position of the third and fourth tracklaying units.

Abstract: A pendulum brake for cushioning pendulum movements, especially for grab buckets of hydraulically operable earth dredges in which the pendulum brake is arranged at the free end of the shank. A grab bucket holder and a drum are by means of fitting keys non-rotatably connected to a bolt which serves as shaft and is rotatably journaled in bearings at the free end of the shank. The drum cooperates with two clamps provided with brake linings while the clamps embrace the drum and by means of a clamping screw and dish springs exert a pressure upon the drum.

Abstract: A flat metal plate is first formed into a suitable segment of a large generally spherical body. It is then properly positioned on a horizontal cradle and its edges cut vertically as if from infinity, i.e. so that they are all parallel. A cutter then traverses the pre-cut edge to form the proper contour for welding. The pre-cut edge itself forms an accurate fixed reference and cooperates with guides on the face of the curved plate to keep the axis of the milling cutter tool substantially perpendicular to the surface of the plate at the point of milling contact. When all segments are so made and then joined, the resultant generally spherical body will be within substantially closer tolerances.

Abstract: A type drum comprising a shell formed as an open network of rows and columns with type characters being formed at the intersections thereof, the shell being attached at one end by struts to a hub located within the shell and spaced therefrom and a combination of the type drum and structure for releasably mounting the drum onto a support such that the drum may rotate relative to its support.

Abstract: An adjustable type connector menas for a wrought iron railing section having top and bottom rail elements of inverted, generally U-shaped cross-sectional construction includes a pair of plate-like members adapted to be assembled to an end of one of the rail elements in opposed, paralleling relation with one another, with a first of the members disposed within the rail element above and in seated relation with a pair of opposed, inwardly extending right-angle abutment means formed integrally in the sides of the rail element and with the second of the members disposed along the underside of the rail element in engaged, bridging relation with the extremities of the sides of said rail element. The plate members are adapted to be operatively coupled with one another to retain the rail element in compression therebetween through means of a mounting bolt fitting through an aperture in the second of the members to within a suitably tapped aperture in the first of the members.

Abstract: An adjustable bimetal snap disc thermostat is disclosed in which a leaf spring acts at its center to apply a force to a bimetal snap disc to alter the operating temperature thereof. The force of the spring applied to the disc is adjusted by an operating member which simultaneously moves both ends of the spring with respect to its center. The operating member is located on the side of the thermostat switch remote from the disc and is provided with projections which extend around opposite sides of the switch to the spring. With this structural arrangement, small adjustment travels are required for a given adjusting spring and the thermostat is constructed in a compact manner, which is symmetrical about the center axis of the device.

Abstract: A multiple bimetallic snap disc thermostat is disclosed in which two series connected switch mechanisms are respectively operated by two concentric bimetal snap discs having the same diameter. One snap disc is thermally automatic in operation to open and close its associated switch upon reaching its calibration temperatures. The outer disc is a one-shot disc which does not automatically reset and cannot be manually reset after operation. The two discs are mounted in a single, disc retaining cup, and are spaced by a ring positioned between their peripheries. This allows said discs to be formed of the same size and provides easy mounting. A single fixed contact member provides the fixed contact for both switches. The contacts of the switch associated with the automatic disc are capable of repeated operation whereas the contacts of the switch associated with the one-shot disc are not structured for repeated cycling.

Abstract: A single-phase induction motor provides a plurality of serially connected main winding coils and a plurality of corresponding auxiliary winding coils each spaced in quadrature from a corresponding main winding coil. Each auxiliary winding coil is energized by the current induced in a serially connected pick-up coil located within a stator slot containing the quadrature main winding coil in response to the energization of the main winding coil for providing a starting torque to the rotor. Each auxiliary coil contains a first predetermined number of turns wound in a first direction within one stator slot and a second predetermined number of turns wound in a second direction located in an adjacent stator slot for increasing the resistance-to-reactance ratio. Each pick-up coil contains approximately one-half the turns of each auxiliary coil which, in turn, has a substantially lesser number of turns than each main coil.
