Detailed Description of Preferred Embodiments Figure 1 shows a perspective view of a peeler according to the invention separated from the cover for clarity. The operational features of this embodiment will now be described.

The peeler of Figures 1 to 7, has a housing (11) and a blade support arm (40) rigidly connected thereto and forming an integral part thereof. The motor (19) lies longitudinally within the housing and the housing is designed to accommodate a single battery.

A gearing arrangement is requ.;red to transfer the longitudinal rotational movement of the motor shaft to the reciprocating longitudinal motion of the blade (27). This arrangement is shown in Figure 5. The shaft of the motor is fitted with a drive cog (50) which engages a crown wheel (51) which rotates about an axis transverse to the peeler and motor shaft. This crown wheel also acts as a sma]l flywheel. An eccentric cam (52) is formed on the boss (53) of the crown wheel (51) and engages with a slot (32) formed in the end of a drive arm (29) for driving the blade. This slot is arranged in a transverse orientation so as to impact : . , . . :
', ' ., , , "~: , , , ' ' ' '; ',, ' . ~' ' .~ '.,:
', , ; ' ', ~^ 204272~ -substantially reciprocating motion in the longitudinal direction to the drive arm. To ensure substantially longitudinal direction of motion, the drive arm reciprocates within a guiding channel formed by ridges (55). The arm is connected directly to one end in the blade and forms a slide (129) which reciprocates within the guiding channel.

The distal end (80) of the blade (27) is formed with ears or lobes (~1). These lobes are fitted with respective bushes (82) to allow the blade to slide within but remain captured by a channel (90) formed at the distal end of the support arm (40) of the peeler. The channel is formed by a U-shaped ridge (92) formed around the end of the support arm and having an overhanging lip (91), the lip (91), ridge (92) and arm (40) defining the channel (90) withln which the bushes reciprocate. A hole (93) is ~ormed~ln the ridge at the very end of the arm (40), defining the end of the channel and allowing the end of the blade to extend therethrough. The hole provides easy cleaning of the end of the blade and prevents build up of foreiqn material which may interfere within the operation of the blade if the channel was formed in a blind hole.

''' " 2~2721 :

Alternatively, as shown in Figure 8, the other end of the blade may be connected to a small slide (56) which is able to reciprocate in the longitudinal direction along a small slot formed in the distal end of the blade support arm (40). Ridges (57) may be formed along the slot to guide the slide in its ~ ;;
movement.

It should be realised that the blade may be permanently secured to the drive arm and slide or it may be removably mounted so that it can be reversed or replaced.

The bl~ade may also be sharpened on both sides to allow the peeler to be used from both sides.
Alternatively, the blade could be sharpened differently on each cutting edge for cutting or peeling different items. Serrated blades are advantageous as the teeth cut the skin of the item being peeled by a sawing action as the blade rapidly oscillates.

The support arm has been shaped, as shown in Fi.gure 3 to form a smooth guide surface (28) for yuiding items to be peeled to the blade on both sides of the arm and the blade is double sided to allow peeling from either side.

Alternatively, the guide (28) ~ay be a special -~
slide fitted to the support arm as shown in Figure 8 or it may be a roller fitted to the support arm, preferably, removably fitted as shown in Figure 9.
.:
The peeler housing (11) has four main sections. A
main housing part (12) which includes the blade support arm (40), control switch (20), motor chamber (60) and battery chamber (61). A motor housing (58) in which the motor (19) is fitted and a battery lid (173 for covering the battery ~;
chamber, connect to the main houslng. A cover (118) completes the peeler. ~ ;
: ~ ' '' ' - .
From Figure 2, a contact strip (62) connectin~ the ~- -negative terminal of the battery to the motor via -the control switch (20) can be seen. The end of .; .
the negative contact strip bears against the body --of the motor to complete the electrical circuit -when the peeler is switched on. A positive terminal contact strip (63) is fitted to the motor housing and can be seen in Figure 5. This contact strip is connected directly to the positive ;~
terminal of the motor (19).

embodiment are further illustrated in Figures lo &
1 1 .

In Figure 9, the peeler (10) is shown in the closed or storage position. The peeler has a housing (11) which can be divided into two major sections, the main housing (12) and the auxiliary housing (14).

he main housing (12), forms a handle for holdlng the peeler and accommodates two batteries used to power the motor (19) is shown moxe clearly in Figure 10. The auxiliary housing is pivotably attached to the main housing to allow the auxiliary housing to pivot from a closed position to an open or operational position. The motor (19) although located within the main housing is secured to the auxiliary housing and rotates within the main housing as the auxiliary housing rotates.

' The auxiliary housing (14) has a turret portion (25) within which the drive end o~ the motor (19) is located. The motor i5 secured to the turre-t portion and the lower portion of the turret portion is captured within the main housing for rotation with respect thereto by a ridge and channel arrangement. Rotation of the turret is restricted by stops (26) located on the auxiliary and main -20~272~ ~

housings.

A switch (20) connects the battery contact (21) to the motor contact (22). The other battery contact (23) is connected to the motor by a wiper contact (24) bearing on the frame or casiny of the motor to complete the electrical circuit. Motor contact (22) is fixed with respect to the motor so that as the motor is rotated within the main housing, the switch is unable to cause the arm of the battery contact (21) to contact the motor contact (22) until the auxiliary housing is in the operational position (as shown in Figure lo). This prevents accidental operation of the peeler when it is closed.

,: , : .. ..
The~ auxiliary housing sup~orts the blade (27) and the guide arrangement (28). The blade (27) is ca~rried by a drive arm (29) which is connected to thé housing by supports (30) which are flexible in substantlally one direction only. The drive arm is connected to the motor by an eccentric cam arrangement arranged to move the arm and thus the .blade to and fro along a substantially linear path.

The eccentric cam arrangement comprises a small ~flywheel (37) mounted to the drive end of the motor ~ 2 7 2 ~

- 11 - , shaft. Located on the flywheel is an off-centre spigot or cam (31) which enga~es with a slot in the drive arm to drive the arm and thus the blade along a path which lies substantially in a single plane.
A cover (18) conceals the connection between the motor and the drive arm.

The guide arrangement (28), in the form of a roller (34) and a roller carrier ~35) supported by the auxiliary housing (14), guides the object to be peeled towards the blade. The depth of cut is varied to suit the thickness of the skin of the item to be peeled by firstly, the initial gap between the roller and the blade and secondly, by the flexible nature of the drive arm and the supports (30). Although the supports (30) are substantially flexible in one direction only, i.e.
in the dlrection of oscillation of the blade, they do ~lex slightly in the perpendicular direction allowing the blade to ride up to a position where the depth of cut becomes easy. Thus the depth of cut is automatically adjusted to suit the item being peeled. Alternatively, the depth of cut can be varied by using guides of different heights or spring loaded guides.
