Abstract: A product applicator is secured to the blower tube of a portable air blower and incorporates an adapter nozzle assembly and product storage container. The adapter nozzle assembly is located at a distal end of the blower tube, and includes a substantially hollow tubular housing and a discharge nozzle located inside the housing. The housing has a discharge end and a connecting end adapted for being arranged inline with the discharge airstream supplied by the blower. The product storage container is located proximate the housing, and is designed for storing a product to be discharged through the nozzle. A flow regulator is adapted for selectively adjusting a supply of product from the container to the discharge nozzle.

Abstract: A product applicator is designed for attachment to an outlet discharge tube of an air blower, and includes an adapter nozzle assembly and product storage container. The adapter nozzle assembly is located at a distal end of the blower tube, and includes a substantially hollow elongated housing and a discharge nozzle located inside the housing. The housing has a discharge end and a connecting end adapted for being arranged inline with the discharge airstream supplied by the blower. Suction and supply hoses cooperate to automatically transfer product from the storage container to the discharge nozzle. From the discharge nozzle, the product is broadcast outwardly from the operator to a surrounding area.

Abstract: A protective collar for a boring bit which interfaces with a boring head whereby shear forces developed during a boring operation are transmitted through the collar to the boring head, with minimal shear force being carried by mounting bolts. A collar is connected to a boring bit, wherein a head receptacle formed by the collar seatably receives a boring head with substantially close clearance so that shear forces during boring operations are transmitted from, the boring bit to the boring head through the collar. The preferred collar is fabricated from a pipe section, such as for example steel seamless pipe. In one embodiment, a bit recess is cut for interfacing with a boring bit at the head face connection thereof. A head recess is cut opposite the bit recess for providing an exit for the water spray from the nozzle thereof. In another embodiment, the collar has an inclined face with bores alignable with the bores in the boring head when the head is mounted within a receptacle in the collar.

Abstract: A collared boring bit which interfaces with a boring head whereby shear forces developed during a boring operation are transmitted through the collar to the boring head, with minimal shear force being carried by the bolts. A bit collar is welded to a boring bit, wherein a head receptacle formed collectively of the bit collar and the boring bit seatably receives a boring head with substantially close clearance so that shear forces during boring operations are transmitted from the boring bit to the boring head through the bit collar. The preferred bit collar is fabricated from a pipe section, such as for example steel seamless pipe. A bit recess is cut for interfacing with a boring bit at the head face connection thereof. A head recess is cut opposite the bit recess for providing an exit for the water spray from the nozzle thereof.
