Abstract: Apparatus for forming stator coils, of undulatory type, constituted by multi-lobed turns, for dynamo electric machines comprises a first circumferential series of forming elements located at equal distances from a central axis and equiangularly spaced from each other, and a second circumferential series of forming elements equiangularly located about the central axis and intercalated between the forming elements of the first series. The forming elements of the second series are movable radially relative to the central axis between an outer position, which is spaced from the central axis by a distance greater than the distance of the forming elements of the first series from the central axis, and an inner position which is spaced from the central axis by a distance less than the distance between the forming elements of the first series and the central axis.

Abstract: A tool for applying banding clamps is provided with means for applying a substantially even amount of force across the transverse direction of a strap to hold the strap in a desired position wherein the force applying means comprises a plurality of superposed levers having means for holding the superposed levers in assembled relationship but permitting relative movement between the levers.

Abstract: A power transmission chain for a sprocket drive is constructed of at least two types of toed links, one engaging sprocket teeth with their outside flanks and the other engaging sprocket teeth with their inside flanks. The links are assembled as uniform sets of links of the same type, in a regular or random mixture of sets. To distinguish the types of links, one type has a curved or arcuate back and the other a flat, generally planar back. An improperly located link can be easily detected in the assembly of links.

Abstract: Single and multi-phase, multi-pole arrays of adjacent equivalent current loops are formed in a self-supporting structure as wound. The multi-pole windings are formed by zig-zag winding elements having peaks and troughs. The peaks and troughs of each winding element form alternate halves of adjacent effective or equivalent current loops. When the peaks of one winding element are aligned with the troughs of another, the two elements provide a single phase ring of adjacent coupled current loops equivalent to the conventional separately wound coils. However, the current loops are already in a correctly positioned and oriented array as wound. The filaments of one winding element cross over the filaments of another intermediate the peaks and troughs and current passes in one direction through the first element returning in the opposite direction through the second. Multi-phase windings in a variety of configurations are described.

Abstract: Apparatus for repairing a section of chain having a closed rectangular frame and a hydraulic ram located within the confines of the frame. The frame has a pair of spaced parallel side rails, a front end member connecting one end of the side rails, and a rear end member connecting the other end of the side rails. Each side rail has a U-shaped downwardly opening notch located between the front end member and the rear end member to lie over a chain to be worked on. An anvil is located on a face of the front end member and the front member is removably connected to the side rails so it may be reversed relative to the side rails to locate the anvil within the confines of the frame when connecting chain sections and outside of the confines of the frame when disconnecting chain sections. The ram has a first head which contacts chain connecting pins to disconnect chain sections and a second head which contacts a link to connect chain sections.

Abstract: A non-expansible linkage bracelet has a basic skeletal structure made up of interlocked sets of top and bottom links covered by decorative shells which also are interlocked with the top and bottom links.

Abstract: A tool which loops the end portion of the outermost convolution of a spiral wire binder around the neighboring next-to-the-outermost convolution while the convolutions of the binder extend through the perforations of a stack of paper sheets and the binder is located in a preselected position has a knife which trims the outermost convolution and thereupon bends the end portion of the outermost convolution to a position of parallelism with and proximity to a stationary surface. A looping device which is mounted at the forward end of a rotary reciprocable shaft is thereupon caused to engage the bent end portion in response to forward movement of the shaft and to loop the bent end portion by moving it along the surface and around the neighboring convolution in response to rotation of the shaft.

In addition there is a unique relationship between the cross sectional areas and configurations of the ends and sides of the link shown and described.

Abstract: A tie gun for applying a flexible tie around a roll or bundle, the tie having an apertured head through which the tail of the tie, after looping around the roll or bundle, is threaded, tensioned and locked in position, the gun incorporating an indexing means in the form of a rotary drum which advances successive ties, tail forward, into the path of a push rod driven by a trigger actuated, pneumatically operated piston so that the push rod performs a rearward stroke during the second part of an operating cycle and in so doing indexes the tie feed drum and simultaneously turns the buckle of an advanced tie into a tail receiving position, thus completing loading of the gun in readiness for the next operating cycle during the first part of which the push rod moves forwardly to push the tail around the roll or bundle to be tied back through the pre-oriented buckle ready for tensioning and locking.

Abstract: The invention relates to a method and a machine for cutting off leads of specific length from electric wire and for processing and equipping the ends of the wire leads. The machine comprises an endless conveyor which bears pairs of close-set clamps and a paying-out station for the wire which pays out the latter tangentially to the conveyor. Cams cause the clamps of each pair to pivot by a quarter revolution in reverse direction from one another. A balance rod forms in the wire situated between two clamps, loops of specific length.

Abstract: A machine for the manufacture of chains of the "rope chain" type for the goldsmithery industry, in which each link is taken from a spiral of wire by means of one or more cuts tangential to the internal profile of the winding. The cuts can be simultaneous or consecutive. The cutting unit includes a pair of blades, the cutting plane of which is adjustable with respect to horizontal so that it can be perpendicular to the coil winding to be cut; it also oscillates between two cutting positions in order to obtain separation of the link with two consecutive cuts in correspondence to two intermittent, 180.degree. one-way rotations of the coil. For chain-linking, a calibrated passage with a decreasing section is provided, in which the take-up unit, after having united a link to those already joined, forces the chain to advance, producing closure of the links with partial overlapping of their contoured extremities.

Abstract: Methods and apparatus are disclosed for continuous-line fabrication of helically wound spirals of desired cross-sectional configuration, such as planar surface spirals, for assembly into conveyor belts. In-line wire shaping and handling procedures and apparatus enable consistently reliable production of uniformly shaped spirals at commercial production rates. Round wire from unsupported coils is shaped in line and controlled as directed to a winding mandrel. Orientation of the shaped wire about its central longitudinal axis, winding tension control, presetting a longitudinal camber in the shaped wire, and wire shaping control are used to compensate for changes in mechanical characteristics of the wire or wire diameter, which occur along the length of a coil, without affecting established winding machine parameters such as lead-in angle for the wire or longitudinal location along the mandrel for starting helical winding.

Abstract: An alignment tool is formed by a pair of mutually interacting comb-like members which, in the open position, receive a plurality of pin terminals depending from a connector between the tines and, in the closed position, the tines engage the pin terminals from opposite sides in trapping them and forcing them to a correct aligned position. After mounting of the terminals into respective apertures of a circuit board or the like the tool is released and, because of its relatively thin dimensions, can be readily removed from between mounted and mounting members.

Abstract: An electronic component lead straightening device and method for conditioning, or reconditioning, electronic devices having an elongated body portion of possible different sizes and materials, and a plurality of metal leads extending from opposite edges of the body portion. The leads, for appropriate use of the electronic component in a circuit, such as a printed circuit on a mounting board, requires their disposition at a preferred predetermined angle to the body, and in substantial parallel mutual relationship, one to another.

Abstract: A wire basket for holding the root system of a plant in a ball of earth has a continuous wire strand aligned to form a tubular grid consisting of a plurality of longitudinally oriented bight strands, and a plurality of helical coils of the wire strand laid about the tubular grid, the crossing points of the bights and the coils being welded. The wire basket is made from a continuous wire strand by laying the strand in a series of back and forth bights aligned in the form of a tubular cage open at both ends, helically coiling the wire across the bights to form a continuous helical wrap, and welding the wire at the crossing points. The basket is formed on a collapsible mandrel having a central shaft, a hub member mounted on one end thereof, and a plurality of radial arms pivotally connected at one end to hub member and circumferentially spaced around the shaft, the arms being adapted to be swung toward and away from the shaft, and to be held at regulatable angles relative to the shaft.

Abstract: A cyclical machine forming tool utilizes positionally justified form knives so that, nominally, a selected 80 out of 120 total stripped wire ends of flat ribbon cable may be selectively simultaneously formed, for bent, into a contour such as is useful for soldered attachement to printed circuit cards. Positional justification of wire-forming hammer elements called form knives, nominally 41 in number, across a variable distance, nominally 1.676.+-.0.009 inches, is expediently repetitively accurately accomplished by wedging them apart with interspersed counterposed knife elements, nominally 40 in number, called adjuster knives.

Abstract: An apparatus for treating the surface of a dental inlay for a tooth has a cup enclosure with a restricted opening therein. A hollow stem is slidably received in the cup and releasably held in a chosen position. An inlay holder is at the end of the stem within the cup enclosure and in the path of a stream of grit particles projected from the reservoir through a nozzle extending through the opening into proximity with the inlay holder.

Abstract: A removable cartridge for insertion in a shrink forming machine having a multiplicity of circumferentially arranged radially movable machine jaws. The cartridge fits inside the machine jaws and is insertable and removable as a unit. The cartridge comprises a multiplicity of circumferentially arranged, radially movable cartridge jaws each engaged by a respective machine jaw to move the cartridge jaw inwardly. A die is mounted on the radially inward end of each cartridge jaw. Guidance structure protects against any substantial deviation by the die from a precise radial path of movement. Structure is provided to enable the cartridge jaw to absorb the load, developed during a shrink forming operation, within the limits of the relatively commonplace physical properties of the material of which the cartridge jaw is composed.
