摘要： A heating coil assembly for use in an air blower device has an annular support element, a first end cap, a core having a heating coil spirally wound thereon, a sleeve surrounding the coil and core, and a second end cap. All components have a centrally disposed non-circular bore therein for receiving a heavy gauge non-circular wire retainer, swaged at one end, which extends through the entire assembly and is retained by a press washer at an opposite end. The interior of the sleeve is spaced from the coil forming an axial channel for air flow over the coil. Axial openings in the end caps form air inlets and outlets for the channel. The coil has several leads, at least one of which extends through an axial opening in one of the end caps. The heating coil assembly has a small number of components, which are easily assembled and simultaneously axially and radially positioned and retained relative to each other by the wire retainer.

摘要： A tine holder for holding a plurality of aerator tines has a plurality of substantially vertical, tapered bores. A tapered collar is adapted to be received in each bore with the collar being split so that the collar contracts as the collar is slid into the bore. The upper end of an aerator tine is inserted into each collar before the collar is inserted into the bore such that the contraction of the collar as the collar is thereafter slid into the bore will suffice to tightly grip and hold each tine in the tine holder. A tool is provided for providing enough leverage on the collar to slide the collar over final portions of its movement as the collar slides into the bore during tine installation or to slide the collar over beginning portions of its movement as the collar slides out of the bore during tine removal.

摘要： A triplex trim mower (100) including a vehicle (102) having two front drive wheels (104) and one rear steerable wheel (106). Mounted generally forward of the front wheels (104) are two reel-type cutting units (108a) laterally offset about the longitudinal axis (110) of the vehicle (102). Mounted between the front and rear wheels and substantially centered between the forward cutting units (108a) is a rear reel-type cutting unit (108b). A lateral support frame (137) is incorporated into the main frame of traction vehicle (102). The cutting units (108) are supported by a lateral carrier frame (144) which is slidably engaged to lateral support frame (137) such that carrier frame (144) can move laterally relative to support frame (137). A hydraulic cylinder (158) permits carrier frame (144) to be laterally displaced under operator command. Second and third hydraulic cylinders (131) permit cutting units (108) to be moved between a transport position and an operating position. A single joystick (118) permits the operator to control all aspects of cutting unit position including transport or operating position and lateral offset position.

摘要： A steering and suspension mechanism for use with a vehicle (1) and including a steering gear (14) interconnected to a steering wheel (8) through a series of universal joints (10, 11, 12, 13, 87). An output of the steering gear (14) is connected to a Pitman arm (21) which extends from a point (31) relatively near the axle (34) to a point (22) relatively far from the axle, where the Pitman (21) is pivotably interconnected to a pair of tie rods (25, 26). Extending upwardly from the wheels (6, 7) are a pair of A-frame members (40, 81) which pivotably support end caps (42, 47). A pair of coil springs (45, 46) are retained between the end caps, the faces (50, 51) of the end caps being preserved in a parallel relationship by linkages (56, 61), thus preventing buckling of the coil springs (45, 46).

摘要： A hot air gun or blower of the type usable for blistering paint on a painted surface for easing the removal of paint thereof has a housing with internal brackets supporting and retaining a switch assembly, a circuit board, a motor having an impeller, a motor mount, a shroud surrounding the impeller, and a heating element. The internal brackets supporting these elements are configured so as to provide a number of air passages between the elements and the interior wall of the housing. In addition to drawing air through a rear portion of the gun, air is drawn through an annular opening in the front of the gun between the cover for the heating element and the housing. The air thus passes over the covered heating coil and is preheated before being blown by the impeller directly over the coil for primary heating. At least one wave-like flange is received between spaced interior brackets in the housing for providing a press fit of the components between the two housing halves, thus eliminating the need for mechanical fasteners for mounting the components of the gun.

摘要： An apparatus for selectively transmitting power between a rotating shaft and a belt including an integral brake member. The apparatus includes a pulley affixed to the shaft and which frictionally engages the belt. The pulley includes a pair of sheave halves which are reciprocable axially with respect to each other between belt engaged and disengaged positions. The integral brake member is mounted about the shaft between the sheave halves and affixed against rotation with the shaft. In the disengaged position the belt drops onto the brake member and is brought to a rapid stop.
