Abstract: A method of manufacture of a plurality of brushes having heads of foam plastic, the heads of the plurality being produced simultaneously by stamping and securing around the head end of each brush handle. Various shapes of brush head can be manufactured, and the head end of the handle can be sized and shaped as desired to produce a brush head of desired size and shape.

Abstract: An amusement ride, especially a trailer mounted amusement ride, in which passenger cabs, or compartments, are suspended from a track which has one reach extending longitudinally along the trailer on the outside and another reach inside the trailer following a sinuous path therethrough. The track portion outside the trailer is detachable therefrom for transporting the ride from place to place. The trailer vehicle is also adapted for being coupled to another trailer vehicle in end to end relation to form an elongated ride. The passenger cabs, or compartments, have individual drive motors thereon for propelling the cabs along the track and each motor is battery powered by a battery on the respective cab. Conveniently, battery charging rails are provided inside the trailer so that the batteries are charged while the cabs are moving inside the trailer and the cabs run solely on battery power while outside the trailer.

Abstract: A signal system for an automotive vehicle, especially a system for giving an early signal to a following vehicle and particularly characterized in that an amber light visible from rearwardly of the vehicle is illuminated when the engine is running and the vehicle is not accelerating or braking. When the vehicle is accelerating by depressing the accelerator pedal the amber light changes to green and when the vehicle is braked as by applying the brake pedal, the signal light changes to red. When braking while the turn signal is operated, one red lamp is illuminated continuously while another is illuminated intermittently and alternately with the amber lamps. When the four-way flashers are turned on all the turn signal lamps alternate with the amber lamps. In this manner, clear and distinct signals are provided, especially for a vehicle following the vehicle having the signal system thereon.

Abstract: A heated dryer drum consisting of a peripherally closed cylindrical shell with dryer heads engaging the shell at opposite ends thereof and each comprising a central bearing journal for rotatably supporting the drum. Included inside the drum is at least one tie rod extending between and connected to the dryer heads near the centers thereof. The dryer heads are axially resilient and preloading of the tie rod, or tie rods, preloads the dryer shell. The dryer heads advantageously taper in thickness from a thicker hub portion to a thinner peripheral portion, with the peripheral portion engaging opposite ends of the dryer shell. The tie rod, or tie rods, may be heated during installation so that, upon cooling, a desired preload will be imparted to the dryer shell. Furthermore, spring means can be incorporated in the tie rod, or tie rods, for controlling the preload on the dryer shell.

Abstract: A slotting cutter in which a disc is provided with insert pockets on opposite sides thereof with replaceable cutting inserts of hard wear resistant material mounted in the pockets. The inserts are clamped in the pockets by a wedge which forces the inserts against the rearward and bottom walls of the pockets thereby providing extremely firm support for the inserts. When the disc is viewed in the circumferential direction, the inserts are in overlapping relation and thereby cooperate to cut slots in a work member.

Abstract: A grooving and cut off tool in which a barlike holder is provided with a thin blade secured thereto at one end and projecting outwardly therefrom. The blade has a groove extending longitudinally along the upper edge thereof and a hard wear resistant insert is mounted in the groove near the forward end thereof.A clamp member is provided which is secured to the bar-like holder by a screw and which has a portion also engaging the groove in the blade-like member rearwardly of the insert and with the clamp member having a resilient tongue engaging a notch provided in the top of the insert. The clamp member has an abutment region engaging the rearward end of the insert and the clamp member is adjustable in the fore and aft direction of the blade member to compensate for change in length of the insert when it is ground off at the outer end.

Abstract: An earthworking blade arrangement, such as for a grader or snow plow blade or the like, in which a steel blade is mounted on the lower edge of a moldboard and extends downwardly therefrom while an axially segmented blade is secured to the lower edge of the steel blade and extends downwardly therefrom and is provided with hard wear resistant inserts mounted in the lower edge thereof and which forms the working edge of the blade assembly. Advantageously, the axially segmented member extends a substantial distance upwardly along the back of the steel blade and is bolted thereto.

Abstract: A method and apparatus for removing tread from tires preparatory to retreading of the tires in which a tire is mounted on a support and inflated and rotated on the axis of the tire. The tread is removed from the tire by a cutter disc which has cutting elements mounted thereon in an annular path with the annular path being presented to the periphery of the tire. The cutter disc and tire are moved relatively to cause the annular path of the cutter disc in which the cutting elements are mounted to traverse the tire from side to side and in a single pass across the tire the tread is removed therefrom. The relative movements between the tire and the cutter disc are under the control of a cam so that the proper contour is imparted to the periphery of the tire.
