Abstract
The clipper is driven by a flexible shaft from a stationary motor supported by a stand clamped to an edge of a grooming table. Because the motor is not incorporated in the clipper casing as characterizes prior art clippers, the casing is lighter, operates at a cooler temperature and can be made more powerful by utilizing a motor of higher rated horsepower and rpm than the smaller type motors incorporated in a clipper casing.
Claims6
An improved clipper to be used in place of a prior art clipper of the type incorporating a motor which is manually moved with the clipper for grooming an animal placed on the surface of a grooming table, said improved clipper comprising, in combination:
- (a) a clamp stand for securement to an edge of said table and having an upwardly extending support bar;
- (b) an electric drive motor having a rated horsepower and rpm substantially greater than that for said motor of said prior art clipper;
- (c) attachment means for securing said drive motor to the upper end portion of said support bar;
- (d) an elongated clipper casing having front and rear ends and dimensioned intermediate its ends to be easily held with one hand;
- (e) a clipper blade assembly holder at the front end of said casing for holding a clipper blade assembly comprised of stationary blade teeth and movable blade teeth;
- (f) an elongated shaft extending axially within and bearingly supported by said casing, the forward end of said shaft terminating short of said holder and including an eccentrically mounted drive disc, and the rear end of said shaft adjustment to the rear end of said casing having flexible shaft coupling means;
- (g) a flexible shaft coupled at one end to said coupling means and at its other end to said drive motor;
- and
- (h) a lever element pivoted intermediate its ends in the forward portion of said casing for oscillating movement about an axis normal to the axis of said shaft, the rear end of said lever element terminating in a cavity receiving said eccentric disc so that rotation of said shaft will result in oscillating movement of said lever element by said disc, the forward end of said lever element terminating in a drive finger receivable in a clipper blade assembly when positioned in said clipper blade assembly holder to oscillate the movable blade teeth of the assembly relative to the stationary blade teeth
- whereby said greater horsepower and rpm of said drive motor assures that the shear oscillation frequency of the movable blade teeth is maintained substantially constant under load, said greater horsepower also permitting a greater amplitude of oscillation to be used compared to the amplitude of oscillation of said prior art clipper and whereby the use of said flexible cable results in less heat being generated in said casing and provides for a lighter and more easily manipulated clipper compared to said prior art clipper.
