Abstract: An impact tool such as, for instance, a hammer, having a pre-formed fiberglass handle. The handle includes a handle portion and a head portion, the latter being receivable in a socket in the striking head of the tool, with the head portion comprising a ribbed section and a non-ribbed section, with the ribs extending only lineally on the head portion generally lengthwise of the handle, and disposed in spaced relation circumferentially of the head portion, and with the non-ribbed section disposed adjacent the ribbed section and diverging rearwardly in the direction of the handle portion.

Abstract: Process for bleaching wooden articles by sequentially treating the articles with sodium carbonate, a hydrogen peroxide mist, and weak acid, with intermediate drying operations.

Abstract: An improved precipitation hardening or maraging stainless steel for use in Tubular Sporting Implements, particularly golf shafts containing chromium, molybdenum and nickel, the sum of said chromium, molybdenum and nickel being at least 18% and not exceeding 25%, at least one element selected from the group consisting of aluminum and titanium in a maximum of 1.30%, carbon in a maximum amount of 0.06%, manganese 0.50% maximum, silicon 0.30% maximum, the balance being essentially iron and incidental impurities.

Abstract: Apparatus for cutting vegetation comprising a disc mounted for rotation in a generally horizontal plane, a support member protruding from the disc for receiving a cutting blade, an elongated, rigid plastic cutting blade pivotally mounted on the support member and a counterbalance to the cutting blade on the disc for stabilizing the apparatus; the cutting blade extending radially as the disc rotates, to cut vegetation in its path.

Abstract: A radio frequency antenna comprising a shaft fabricated from dielectric material, and first and second conducting means disposed on the exterior surface of the shaft, the conducting means including linear conductors located on opposite sides of one portion of the shaft and intertwined insulated coils on a second portion of the shaft connected to the respective linear conductors. Tuning members can be connected to the conducting means for selectively changing the resonant frequency of the antenna.

Abstract: A cordless earth tiller has a housing mounted upon wheels and including a handle for guiding and controlling the tiller and tilting the same in a fore-and-aft direction. A power driven crankshaft disposed forwardly of the wheels carries a plurality of arms which depend from crankpins of the crankshaft and are provided at their lower ends with tines. Links are pivotally connected at one end to the arms and at the other end to an axle of the wheels whereby rotation of the crankshaft causes a tilling or cultivating motion of the tines. The tines sequentially impinge upon the ground in a substantially vertical direction and proceed through the ground at a rearward inclination to draw the tiller through the ground in response to rotation of the crankshaft. Modifications comprise the use of harrowing disks as wheels and the substitution of ice chipping tools for the tines, etc.

Abstract: A base station radio antenna comprising a bracket having a first section for attachment to a support structure and a second section for receiving antenna whips, an antenna whip extending upwardly from a central opening in the second section of the bracket, and a plurality of antenna whips inclined relative to the upwardly extending antenna whip and extending generally downwardly from openings in the second section spaced radially from, and equi-angularly around, the central opening.

Abstract: A pendulum type hoe has a stirrup-shaped blade mounted to the fork of a handle for limited articulation. Inturned flanges of the blade engage hourglass shaped openings in the fork arms, the flanges being retained between reinforcing bars which project through the openings and afford strength, wear resistance, and limited resilience to the blade. The fork is made in two separable parts whereby any component of the hoe may be replaced.

Abstract: There is disclosed herein a battery operated power grass shear wherein a fixed blade and a superimposed laterally oscillating movable blade have forwardly projecting, laterally spaced cutting teeth, the planes of said blades being tilted convergently relative to each other in the forward direction, the teeth of the upper and lower blades contacting each other only at the cutting edges thereof during cutting movements, and each tooth of the movable blade beginning its cutting stroke at a different time in each cutting cycle.

Abstract: A pair of grass shears comprising a stationary blade to which a first handle is affixed, a movable blade operatively connected to a second handle, first and second cooperating slots and posts in the respective blades for guiding the movable blade both in the direction of the handles and in a rotational path across the fixed blade as the handles move the blades between open and closed positions.

Abstract: A tubular structure for a tennis or like game racket is formed from modified metal tubular members arranged in a spaced oval relationship forming a racket portion. The modified tubular members include an annular recess and retaining means for retaining individual holding means to maintain the racket cross strings permanently taut and in a spaced relationship.

Abstract: There is disclosed herein a tennis racket comprising a frame member shaped to provide a racket loop, a throat comprising convergent portions at one end of the loop, and a handle. A yoke is provided across the throat to close the loop, said yoke being of laminated construction and having laterally directed grip portions embracing the frame member on either side of the throat. Said yoke is adapted to mount a stringing insert.

Abstract: There is disclosed herein a game racket having a frame formed from a single length of tubular framing shaped into an oval and having parallel extensions for the handle. The extensions are provided with connectors which space the extensions a fixed distance apart and provide interlocking means for securing the extensions to each other. Handgrip means in the form of two complementary sections encase distal end portions of the extensions and the connectors to provide a grip for the racket.
