Abstract: A hose adapter defines a passageway therethrough and has a first connector portion and a second connector portion with the first connector portion being substantially larger in transverse dimension than the second connector portion. A transition portion is disposed between the first and second connector portions. A vacuum device is operatively associated with one of the first and second connector portions, and a hose is secured to the other connecting portion. In one embodiment, the hose adapter has a vent with an associated closure, which is designed to vary the opening in the vent and thereby alter the amount of suction created by the vacuum device. A plurality of interiorly-mounted, inwardly-projecting ribs are provided in the second connector portion to facilitate retention of a hose therein. A vacuum system employing the adapter is disclosed.

Abstract: A swivelable vacuum hose coupler of a grooming clipper vacuum attachment includes a front attachment member attachable to a suction head of the vacuum attachment, a rear hose attachment member attachable to an end of a vacuum hose, and an annular swivel collar rigidly attached to a rear end portion of the front attachment member and rotatably coupled to a front end portion of the rear attachment member so as to hold the rear end portion of the front attachment member in an abutting relationship with the front end portion of the rear attachment member and the front attachment member in flow communication with the rear attachment member and to form a swivel joint with the rear attachment member such that the front attachment member can rotate at the swivel joint relative to the rear attachment member and thereby allow the rear attachment member to remain in a stationary position relative to the front attachment member.

Abstract: A vacuum attachment mountable on a forward end of a hair grooming clipper includes a conduit body enclosing an internal air flow passage between inlet and outlet ends thereof such that flow of hair cuttings entrained in air can be drawn from front cutting blades of a cutting head mechanism of the clipper via the inlet end through the passage to an external hose coupled to the outlet end, and mounting wings integrally and externally formed on the conduit body and extending from opposite sides thereof such that the conduit body and mounting wings define a replacement cover that can substitute for and replace the original equipment cover removed from the forward end of the casing of the clipper in order to enclose the opening in the forward end of the casing of the clipper.
