Abstract: A method of moving and transferring a stack of lumber or the like from a side by side row of stacks wherein the stacks are supported on ground placed chocks positioned at the ends of the stack. The method involves engaging with the tines of a forklift truck a transfer unit provided with a ground engaging support means at its forward end, and lifting the transfer unit with the lift truck tines so that the transfer unit is at least partially maneuverable by movement of the lift truck. The transfer unit is then forwardly and progressively moved under the selected stack by forward movement of the lift truck so that the transfer unit engages the stack and pushes the near chock forwardly and beyond the center of the stack so that the weight of the stack is transferred from the chocks to the transfer unit. The transfer unit supported stack is then withdrawn from the row of stacks by backing the lift truck away from the row.

Each cup member is of a different volume than the other cup members. Removable bottom plate means slidably closes the bottoms of the cup members such that the individual cup members are fillable with a measured material from the top when the bottom plate is in closure relation, and emptied from the bottom when the bottom plate is slidably removed.
Abstract: An improved, more compact microwave equalizer is provided by utilizing a length of coaxial transmission line to which at least a pair of relatively small diameter, flexible, coaxial cable resonant stubs are coupled through film type impedance means. Each coaxial cable stub is disposed adjacent the outer conductor of the transmission line, for compactness, and the length of each stub is minimized by use of high dielectric constant material therein. By shortening the length of each resonant stub and by shunting a capacitor across each resonant stub, the frequencies of the upper and lower band edges of the equalizer's attenuation curve are spread apart, while simultaneously providing the desired operating frequency band. Slots and/or an annular recess provided in the relatively thick outer conductor of the transmission line receive the stubs and the retaining apparatus for the film type impedance means.

Abstract: Pool table croquet game equipment is produced in several components, many of which are the same, for convenience of manufacture, assembly, use, and storage, to play a game on a pool table using pool cues and pool balls in a procedural way very similar to playing lawn croquet. The nine croquet like arches or hoops, through which the pool balls are shot, are equipped at their tops with integral dual direction hollow receivers and at their bottoms with snap on feet, adjustable if necessary for the vertical alignment of the arches or hoops. These nine croquet like arches or hoops are positioned about the pool table top in relative positions similar to the positions of the arches used in playing lawn croquet. To keep them firmly and accurately spaced, they are joined together by using various tubes which are provided in essentially two groups of like lengths. Each tube passes through at least one of the integral dual directional hollow receivers at the tops of the nine croquet like arches or hoops.
Abstract: This float is for commercial fishing trollers and is adjustable so that the same float, after adjustment, may be used with a starboard or port sheer line or a straight line of a multiple line, trolling system. The float element is a relatively long, tall, and thin prism or parallelepiped having desired rigidity and density - the latter to cause it to float high in water. When in use with a fishing, trolling line, it floats with its thin dimension horizontal, thus standing vertical on one of its narrow side surfaces. A bottom plate is connected with the float. In a first embodiment, four holes extend through said plate, with a pair thereof at each end portion thereof, one of each pair toward the center crosswise considered and the others of both pairs toward the same side. An end hook for pivotally mounting an end portion of a rod is detachably connected to a selected hole at each end portion of the float. A center pivot support is mounted on said plate.
Abstract: A blade for a bulldozer. The blade comprises a post of variable, substantially circular cross section varying from a maximum at the top and the bottom uniformly to a minimum at the middle. The post is attachable to a bulldozer. A blade member is pivotally mounted to each side of the post. Each blade member is shaped at its inner end to correspond to the shape of the surface of the post. The blade is adapted to attach to, for example, hydraulic rams to pivot each blade member independently about the post. Thus, upon pivoting, each blade moves around the post while at least maintaining a uniform, small distance from said post.
Abstract: A power driven reciprocating hammer strikes a tool shaft or moil. A split ring of larger diameter than the moil extends about a reduced diameter shank portion of the moil and makes contact with a one-piece bushing, through which the moil extends, when the moil approaches its outward end of travel. The bushing is moved against a body of elastomeric material which is housed within a nose cap. Such material absorbs the remaining energy in the moil and in so doing changes its shape, including by flowing radially outwardly through an axial space provided between the nose cap and the nose end of the housing. Cross pins removably connect axially projecting mounting lug portions of the nose cap to the nose end of the housing.
Abstract: A base supports a chamber having an upper portion that defines an air exit aperture, a middle portion that has a plurality of air entry apertures and a closed, lower portion that forms a soap solution reservoir. An apertured, bubble forming ring is mounted within the chamber for rotation about a horizontal axis and has its lower portion extending into the soap solution reservoir. An air impeller is mounted within the bubble forming ring for rotation about a vertical axis. When the toy is actuated, the apertured bubble forming ring carries films of soap solution from the reservoir into the upward air current emitted by the air impeller to form a multitude of upwardly projected bubbles.
Abstract: A method for manufacturing a self-locking spring nut is disclosed herein. In this method, a spring nut is tapped in its stretched or compressed condition, where a lead or pitch of the spring nut of a helical form is increased or decreased, say 0.5 to 6%. Accordingly, when a bolt is inserted into the spring nut thus prepared, then threads on the bolt undergo a compressive or tensile stress by the spring nut.As a result, the spring nut may be locked on a bolt in any position. This method utilizes an elasticity of the spring nut to be locked on the bolt, rather than interference between the female and the male threads on the nut and bolt, respectively, for instance, interference caused by deforming the configuration of threads or changing a pitch of a male thread relative to that of a female thread. Accordingly, the self-locking nut of the invention may be repeatedly used, without being damaged.

Abstract: A winch mounted to an automobile bumper and having a cable winding drum supported between a main drive housing and an oppositely positioned idler housing. The drive housing connects to the bumper braket by means of a pair of convexly curved mounting lugs which permit limited angular movement of the drive housing with respect to the bumper. The idler housing has a flat mounting surface which fits flush against the bumper bracket surface to prevent such angular movement. Upon distortion or misalignment of the bumper braket, the drum is able to shift angularly with respect to the idler housing, while the other end of the drum maintains a fixed angular relationship with its bearing means in the main drive housing, which is in turn able to shift angularly with respect to the bumper bracket.
Abstract: A slider for use in a slide fastener prevents jamming of a foreign matter within the slider between fastener elements and inner element-guide portions of the slider. The slider has a diverging end and a contracted end, and the diverging end has two openings which are partitioned by an interconnecting web. The two openings lead to two channels which are joined together in the half portion of the slider on the side close to the aforesaid contracted end. The separated fastener elements secured to fastener tapes, respectively, and introduced through the aforesaid channels into the slider are brought into engagement with each other in the aforesaid half portion of the slider. In such a case, a foreign matter, such as a piece of cloth, often jams between the fastener elements and the inner element-guiding portions of the slider.
