Abstract: A fuse holder for a cartridge type fuse is formed of a housing having a fuse transfer region and a fuse contact region in the interior space thereof. A fuse carrier is provided, which carrier is captured within the housing. The fuse carrier is movable between the fuse transfer region and the fuse contact region. A fuse is inserted or removed into the fuse carrier through a suitable opening provided within the fuse transfer region. Within the fuse contact region there are provided fuse contact members which engage the conductive ends of the fuse when the carrier moves the fuse into the fuse contact region.

Abstract: A fuse holder assembly for a cartridge type fuse includes an elongated fuse carrier bar having a cylindrical opening in a fuse containment portion for loosely accepting the fuse therein. The fuse contacts include a conductive spring at the inward end of the assembly and a generally U-shaped spring fuse clip member at the outward end. The assembly includes a recess at its inward end to accept an end of the fuse carrier bar and when the carrier bar is inserted in the recess the inward end of the fuse is brought into contact with the spring. The fuse carrier bar is then pivoted to cause the outward end of the fuse to be captured by the fuse clip. To remove a fuse, the fuse carrier bar is pivoted to pull the fuse out of contact with the fuse clip and the fuse carrier bar is then removed by being pulled outward from the assembly. To insure that only the proper size fuse is placed in circuit, a unique spacing is provided between the spring contact and the fuse clip in the location reserved for that size fuse.

Abstract: An electric motor, such as a rare-earth permanent magnet single airgap direct current motor is provided with generally longitudinally extensive heat transfer or cooling means comprising heat receptor elements adjacent but minimally spaced apart from and parallel the armature. These heat transfer elements are then cooled, as by being thermally connected with external heat discharging or dissipating structure to transfer the heat away from the motor. In one embodiment or modification the heat transfer elements project inwardly from a heat conductive end cap provided on its outer surface with heat radiating fins. In another embodiment or modification the heat transfer elements are hollow and a coolant, such as air, is circulated therethrough. The heat receptor elements may be provided with fins to increase their surface area, with the fins preferably facing the armature structure. The receptor elements are also preferably substantially coextensive with the active portion or windings of the armature.

Abstract: A motor operated circular miter chop saw is pivotally mounted on a generally horizontal axle pivot bolt about which it rotates in a vertical plane with the axle pivot bolt being carried by a cast support base structure. Angular orientation of the work piece is provided by an angularly adjustable fence rotatably carried by the cast base support structure with the fence having a generally downwardly open circularly arcuate groove cooperating with a pair of machined steel pins pressed into the cast base support structure. The cast base support structure is also provided with an arcuate slot to provide clearance for the circular saw blade and leaf spring means are provided carried by the cast support base bias the fence rearwardly so that the pins engage against the inward wall of the fence groove.

Abstract: A locking device for a motor mounting pin extending through the shoulders of support structure is formed with a pair of diverging legs one of which includes an opening that receives the pin and the other of which has an adjustable force applying member thereon engageable with one of the shoulders for affixing the pin in the support structure both axially and rotationally.

Abstract: A storage cabinet containing a folding cutting table of the type having hingedly connected table top panels which may be extended to form a flat continuous table surface or folded into a relatively compact, stacked assembly and stored within the cabinet.

Abstract: A thread handling system for a sewing machine is provided with a tensioning device without a check spring, a thread takeup member for pulling thread from the tensioning device and setting stitches, and a thread holder including a pair of elongated members which grasp and meter thread to a needle and looptaker. The tensioning device is disposed with respect to the operating limits of the takeup member to enable thread to be withdrawn from the tensioning device without being pulled from the thread source and with only slight thread tension.

Abstract: A collapsed barrier is placed in the water in the general path of a detected homing torpedo after which the barrier is erected into one or more generally vertical planes to intercept the torpedo. When the torpedo strikes the barrier an explosive charge is detonated to destroy the torpedo.

Abstract: A crosshead for a scotch yoke mechanism is formed from a generally rectangular blank of sheet steel provided with a generally oval, straight sided opening extending generally transversely medially thereof and a pair of generally circular openings centered and spaced apart from each of the oval opening straight sides, the blank being formed, as on a four slide forming machine generally around two generally parallel lines each being generally extensions of the oval opening straight sides to provide top and bottom generally parallel panels defining a closed end guide track having parallel sides and positioning the generally circular openings in the top and bottom panels and in line to be threaded on a generally cylindrical tubular saw bar of a sabre saw, the blank being further formed to tubular configuration of generally rectangular cross-section by two further parallel bends closing the crosshead on a fourth side on the side of the saw bar opposite the guide track opening.

Abstract: A reverse treadling inhibiting device having an electric motor connected to a sewing machine arm shaft through a one-way clutch and inhibiting the reverse treadling of the sewing machine by utilizing the one-way clutch connection to the electric motor to add inertia and resistance to reverse treadling of the sewing machine.

Abstract: A sewing machine is provided with a spring biased platform and bobbin which are movable by the throat plate of the machine into a position wherein the bobbin is disposed to receive the lower limb of a loop of needle thread and to effect an operative connection between the bobbin and drive shaft providing for rotation of the bobbin as required for bobbin winding. An electrical switch operable by the thread of a full bobbin is provided to discontinue rotation of the bobbin drive shaft.

Abstract: An open bottomed sewing machine cover is tapered and slabbed at one end and provided with novel and improved latch means for use with platform beds, bed frames or bottom bed covers that are indented on the bottom at the ends to accept the latches which of comprises latch levers suspended on leaf springs adjacent the bottom edges of the open bottom provided with inward facing paddles at their lower extremities adapted to be pulled outwardly while the case is lowered over the machine to rest on the table top or over the major portion of a similar case cover for stacking and nesting and after the cover is lowered over a machine as the latch lever is released, the paddles move inward into indents provided adjacent the bottom of the machine to extend beneath the machine to support the machine for carrying.

Abstract: A valve operator is connected to a pipeline valve to control the throughput flow therethrough. A plurality of chambers are formed in the housing including control, balancing, bleed and regulator chambers. A poppet valve and an orifice device are disposed in the bleed chamber to be independently shiftable therein to vary the discharge from the orifice device which is shifted responsive to the pressure in the control chamber, while the poppet valve is shifted responsive to the pressure in the regulator chamber. A reset valve is connected in a reset loop connected between the control and balancing chambers to produce a predetermined delay in balancing the pressure gradient therebetween.The regulating chamber is formed in a regulator section of the housing to be detachably connected thereto so that a plurality of regulator sections can be formed each having a different operative pressure range so that the valve operator is selectively usable for example for high, medium and low pressure operation.

Abstract: In a rotary meter having a self contained cartridge including a stationary core member, a rotor and a rotating cylindrical gate, a removable spider member is utilized to accurately position the cartridge within the meter casing prior to final assembly.
