Abstract: Unattached weights, namely: balls, which are confined and obscured in a housing, are lifted by inner ends of pivotably mounted perches in response to an undesirable, rapacious, and weighty bird, or squirrel, alighting upon, or clasping at the outer, extending portions of the perches. The ball-lifting, perch ends are cradles, and the cradles and balls define a relative, rolling friction therebetween which, in cooperation with a mechanical advantage of the extending portion of the perches vis-a-vis the cradles, demonstrate a diminishing resistance as the perches rotate downwardly and dislodge the unwelcome creature.

Abstract: The well-known, compliant sheet of material which is enwrapped about the juncture of structural units, to form a fluid barrier thereat, has its structure-adhering adhesive admixed with an insecticide or termiticide, to additionally form an insect barrier thereat as well. In an alternate embodiment the insecticide or termiticide is sprayed onto the adhesive.

Abstract: The article of apparel disclosed is a pair of full chaps formed of a substantially inelastic material, and having strips of elastomeric fabric interposed between the teeth of the closing zipper and the edges of the chaps material, to facilitate a continuous form-fit of the chaps no matter how the legs of the wearer flex.

Abstract: A slit, spanning a distance across the top of the vane slot in a cylinder for a rolling piston compressor, safely distributes the stress which occurs in the vane slot. The slit opens onto the bore, in the cylinder, which is provided for a rotary shaft and rotary piston, and onto the vane slot.

Abstract: Inlet valves, with inlet cages, in inlet ports in a cylinder head, and outlet valves, with outlet cages, in outlet ports in the cylinder head, comprise mating combinations of elements which exhibit optimum and proper seating together. The bores and the cages have configurations which, upon elements of one of the combinations being substituted for elements of the other combination, will prevent the seatings from occurring. Consequently, only the correct elements, per combination, will join together and nest in the correct bore and, in this way, the seating of an inlet valve in an outlet bore, or vice versa, is avoided.

Abstract: For mounting a machine element having a bore coaxially on a shaft for rotation with the shaft, there are provided a first member having internal threads, and a split sleeve having external threads adapted to be mounted around the shaft and inside the bore. The threads of the split sleeve have apexes at a uniform diameter when unstressed. The first member is threaded on the external threads of the split sleeve. Also, a second member is spaced from the first member by an amount sufficient to allow the first and second members to embrace opposite sides of the machine element. The threads of the first member and the split sleeve are shaped to cause contraction of the sleeve into fast, gripping engagement with the shaft, as the first and second members frictionally clamp the machine element between these first and second members.

Abstract: A body, plastic molded, comprises a plate with an integral, extending hub, having a throughgoing bore in which to nest a coaxial coupler. The hub has an outer periphery which is uniformly fluted, for holding the hub fast to the inner surface of a hub-receiving hole formed in a wall, floor, or ceiling of a structure, while the plate unobtrusively interfaces the planar surface of the structure. Consequently, a coaxial coupler can be emplaced, securely, without need for a supporting junction box, vertical stud, or any such prop, anywhere in a wall, floor or ceiling.

Abstract: In the embodiment shown, the body is formed of cast aluminum, and is devoid of clean-out holes in the upper and bottom ends thereof. Instead, the clean-out holes are formed in the outer, annular wall, through an annular recess formed in the outer wall, To close off the clean-out holes, a steel band is nested in the recess, in circumscription of the body. Further, the steel band has grooves formed therein in which to accommodate piston rings.

Abstract: A strip of sheet metal stock, having a plurality of serially-arranged holes formed therein is provided for fastening of the strip to a top plate of a building structure. The strip, further, has pairs of tabs formed therein which can be pried up from the plane of the strip, and put into vertical dispositions, to receive a rafter or truss between the paired, and vertically-disposed tabs. Holes in the tabs provide for the fastening of the emplaced rafters or trusses to the tabs. The pairs of tabs are uniformly spaced apart from other pairs thereof a distance which obtains between rafters or trusses according to conventional construction codes. An indeterminate supply of the strip can be stored on, and payed out from, a reel.

Abstract: An elongate, steel rod has a terminal end which defines a wedge, and a handle on the opposite end. Adjacent to the terminal end, there is a barrier provided to prevent excessive travel of the wedge under the limb of a locking clip.

Abstract: A plastic, pliantly limber grub, which comprises the body of the lure has a fish hook and a separate rod set therewithin, and terminations of the hook and the rod have tethering, filamentary material commonly coupled thereto. The coupled terminations are disposed a given distance therebetween, whereas the filamentary material has a free length which is greater than said given distance; this provides for a lost-motion effect, between the body of the lure and its rod, on the one hand, and the fish hook on the other, pursuant to a fish strike on the hook.

Abstract: A guide, serving as a platform for a portable, electric circular saw and the saw base plate, presents a trackway in which, slidably, to receive the base plate, and removably mounts a channel element, thereunder, for abuttingly receiving a workpiece, that is a piece of lumber, against the element for cutting by the saw. In one embodiment, the channel element disposes the lumber for cross-cutting. In another embodiment, the channel element disposes the lumber for rip-sawing. The platform is selectively mounted to a support, in inverted attitude, for converting the circular saw to a table saw.

Abstract: The body of a fishing lure has a rod extending therefrom to which is tethered, by fishing line, a fishing hook. The body has an elastomeric band thereabout, and the shank of the hook and the rod-to-hook fishing line are stowed within the band in a set up, ready to snare a fish. With a fish strike at the hook, the hook and line withdraw from the band, rearwardly of the lure body, while the lure body is trolled or reeled forwardly. In turn, the hook reaches the end of its line-tether, and comes to a sudden halt, whereby the fish is deeply hooked.

Abstract: A housing confines therewithin a saturated sponge, the same disposed for moistening the flap of an envelope. Too, the housing has a entry slot for an envelope, and a switch, with an operating sensor or limb which detects the entry of an envelope into the housing, for the purpose of rotating rollers which (a) move the envelope from the entry slot to an exit, and (b) cause the flap to wipe across the sponge and seal against the body of the envelope.

Abstract: A fluid control valve has a valve guard and a valve seat, and the guard has a circular recess formed in a front surface thereof in which to nest the valve seat. In one embodiment, a pair of valve guards are integrally joined together by a plurality of webs which bridge therebetween via the rear surfaces of the guards.

Abstract: A pair of confronting limbs, which have mutually meshing jaws, clasp the open top of a bag therebetween when a grooved bar slides upon the limbs. The limbs have external rails, and the bar has trackways formed therein to receive the rails slidably therein. The limbs are integral with a twice-folded panel which defines a pouring spout for the subject bag of a portion of the panel; this pouring spout portion is set within the bag.

Abstract: A panel having a suspending hook at a lower end thereof slidably receives an optimum-weight comparison chart. The hook is used to support a basket or sling in which a child is held for weighing. A spring-loaded limb overlies the panel, and has a stylus in an end thereof, with a second hook at the opposite end thereof. The second hook is used to suspend the panel from a tree branch, a beam, or such, and the weight of a child causes the panel to descend, against the biasing of the spring-loaded limb. The stylus is depressed to make a hole in the chart for comparison with an optimum trajectory of weight/development of children of like age, and to keep a record of the measured weight, and to track weight gain or loss with successive weighings and stylus hole-punching of the chart.

Abstract: A hollow through-bolt is threaded internally and externally, at one end, to receive therein a reciprocable, end-threaded rod. A pair of fluid-control valves, centrally bored, are mounted on the through-bolt in spaced apart disposition. The other end of the through-bolt has a shoulder formed thereon for seating one of the valves thereagainst, and the other valve central bore is tapped for threaded engagement with the one end of the through-bolt. A sleeve, slidably engaged with the through-bolt, and interposed between the valves, maintains the one valve positioned against the shoulder.

Abstract: A centrally-bored, elongate body slidably receives rope therethrough, and a rope end tethers a ball thereat. At a handle end of the body, a clothesline tightener or foreshortener is used to clasp the handle-confined portion of the rope to prevent its movement through the body, however by withdrawal of the hollow shaft of the clothesline tightener, the rope is unclasped and can freely be drawn out of a pay out end of the handle, to lengthen the ball-tethered portion thereof, or drawn out of the handle end to foreshorten the ball-tethered portion thereof. The clothesline tightener is slidably and snugly held in the central bore of the body at the handle end thereof.
