Abstract

A gearing arrangement consists of a housing (1) locked over a vertical drive spindle (3) of a food processor, over which, in normal use of the processor, a bowl would be placed. Gear (5), having a vertical spindle (6), engages with gear (4) and has a co- axial frusto-conical bevelled gear (7). Engaging with gear (7) is a correspondingly-angled bevelled gear (8), having an output spindle (9), onto which an attachment, such as a can-opener, cream maker, etc., may be connected. During operation of the food processor, the arrangement enables spindle (9) to be rotated at a substantially lower speed than drive spindle (3), thereby enabling the attachment to be driven at substantially lower speeds than those required in the normal use of the food processor. <IMAGE>

Description

SPECIFICATION A gearing arrangement This invention relates to a gearing arrangement and in particular, though not exclusively, to such an arrangement for a food processor.
Food processors normally include a generally vertical drive spindle, which may be rotated at substantial speeds, over which a bowl may be placed and onto which various attachments may be connected to provide the required processing of food placed in the bowl. There also may be provided an attachment on a lid for the bowl which activates a safety interlock on the processor, so that the motor thereof can be switched on, the attachment thus ensuring that the lid is securely locked into position before any processing may be initiated.
However, this drive spindle arrangement, although suitable for such food processing, mixing, etc, may cause problems if alternative attachments, such as a can opener, cream maker, pasta maker, coffee grinder, etc, were required to be connected thereto and driven thereby, as attachments of this kind are not normally operated by a vertical drive spindle and/or do not normally require such high rotational speeds as those required by the food processor.
It is therefore an object of the present invention to provide a gearing arrangement which substantially alleviates the above-mentioned problems.
According to the invention there is provided a gearing arrangement for conveying the rotational drive from the drive spindle of a food processor to a further spindle disposed with its rotational axis substantially orthogonal to that of said firstmentioned spindle, said gearing arrangement including components arranged to cause said further spindle to rotate at a rate less than the rate of rotation of said first-mentioned spindle.
Further according to the invention there is provided an arrangement, as set forth in the immediately preceding paragraph, including a housing arranged to replace the bowl of said food processor.
The present invention will now be further described by way of example only with reference to the accompanying drawing, the single figure of which shows a sectional view of a preferred embodiment of the invention.
Referring to the figure, a housing, shown generally at 1, includes a base 2 which is locked over a vertical drive spindle 3, provided on a food processor (not shown) and over which, in normal use of the processor, a bowl would be placed. A loosely-fitting input gear 4 is positioned over the drive spindle 3, so that the spindle 3 engages and locates the gear 4 to provide rotation thereof.
An intermediate gear 5, having a vertical spindle 6, engages with gear 4 and has, integrally formed and co-axial therewith, a frusto-conical bevelled gear 7. Engaging with bevelled gear 7 is a correspondingly-angled bevelled gear 8, having an output spindle 9, onto which an attachment, such as a can-opener, cream maker, pasta maker, coffee-grinder, etc, may be connected.
It can therefore be seen from the figure that gear 8 is arranged to provide rotation of output spindle 9 about an axis disposed at approximately 90 to the rotational axis of the drive spindle 3.
A lug 10 may be provided on the housing 1 , so that, when the housing 1 is correctly positioned on a casing of the food processor, the lug 10 can activate a safety interlock, which would otherwise have been activated by a lid of the bowl on the processor, thus allowing the motor of the processor to be switched on, the speed thereof being controlled by user-selective buttons on the processor.
A thumb-wheel 11 may also be provided in conjunction with gear 4 to allow the gearing arrangement to be indexed manually, thus aiding engagement of the gearing arrangement to the processor.
The preferred gearing arrangement in accordance with the invention also allows the output spindle 9 to be rotated at a substantially lower speed than the input spindle, an advantage of this being that the above-mentioned attachments may then be rotationally driven at substantially lower speeds than those required in the normal use of the food processor.
In operation, therefore, rotation of drive spindle 3 causes rotation of input gear 4, which drives intermediate gear 5 and frusto-conical bevelled gear 7, which, in turn, drives bevelled gear 8 and so rotates output spindle 9, thus effectively utilising the vertically-disposed drive spindle 3 of the processor to drive the horizontally-disposed output spindle 9 of the gearing arrangement, to which various suitable attachments may be connected to provide rotation thereof in a substantially vertical plane and at a substantially lower speed than that of the rotating drive spindle 3.
Various alternative gearing arrangements in accordance with the present invention may, of course, be envisaged by persons of ordinary skill in the art.
1. A gearing arrangement for attachment to a drive member of a food processor consisting of means for conveying rotational drive from said drive member to a further member disposed with its axis of rotation substantially orthogonal to that of said drive member, said gearing arrangement also including components arranged to cause said further member to rotate at a rate less than the rate of rotation of said drive member.
2. A gearing arrangement as claimed in Claim 1 and including a housing arranged to replace the bowl of said food processor.
3. A gearing arrangement as claimed in Claim 1 or 2 wherein said drive member comprises a first spindle, the longitudinal axis of which is vertically disposed, and said further member comprises a second spindle, the longitudinal axis of which is horizontally disposed.
