Shafts for Motor Cars and other Machines.
HAROLD WIBMER CLARK, Daisy Bank, Middleborough Road, Coventry, Engineer,
do hereby declare the nature of this invention to be as follows:-
The clutches consist of feathers F1 F2 F3 fitting loosely in recesses in bearings
of wheels W1 W2 W3 Fig. 1. Feathers F1 F2 F3 are pressed against shaft A by
springs (for example P1 P2 P3) of any suitable shape and any convenient position.
In shaft A are slots S1 S2 S3. When shaft A is slid through bearings into such
a position that the feather F1 F2 F3 in the bearings of one of the wheels enter the
slots S S S in shaft A the wheel is thereby conected with shaft.
Slots S1 S2 S3 are so shaped that when shaft A is slid along, feathers F1 F2 F3
can be drawn in or out of the slots St $2 $3 as required, thereby conecting or
disconecting wheels. Fig. 1, shows portion of three wheels in section, each
of which contains in its bearing two clutches and the shaft with corresponding
slots.
Wheel W is shown connected to shaft by feathers F¹.
Wheels W and W are shown with with clutches released.
Fig. 2, shows feathers F F F contained in recesses in bearings, which feathers
are pressed by springs P1 P2 P3 against a sleeve which is placed upon shaft A.
Should circumstances prevent the sliding of shaft, shaft A shall have upon it a
sleeve L which cannot rotate independently of shaft A, but can be slid along it.
On sleeve L wheels W W W can rotate until sleeve L is slid into such position
that the feathers F1 F2 F3 in the bearings of one of the wheels W1 W2 W3 are
pressed by the springs P1 P2 P3 into the slots $1 $2 $3 in sleeve L, thereby any one
of the wheels W W W may be connected with shaft A.
The shape of the slots S1 S2 S3 in sleeve L is such that when sleeve L is slid
along, feathers F1 F2 F3 can be drawn in or out of slots S S S in sleeve L.
There may be any number of such clutches to each gear wheel or pulley, and
any number of wheels or pulleys containing them on a shaft or sleeve.

page_text: of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
(Fig. 1, drawing with Provisional Specification, is a sectional drawing which
shows a shaft upon which there are three wheels which can rotate independently
of shaft untill connected to same by the clutches two of which are shown con-
tained in each wheel shown in Fig. 1.)
The clutches consist of feathers (FF2 and F3 Fig. 1) which fitt losely in recesses
or slots in the bearings of the wheels (W W W Fig. 1). The feathers (F¹ F³
and F) are pressed against shaft (A Fig. 1) by springs (for example P¹ P
and P³ Fig. 1) which springs may be of any suitable shape and in any con-
venient position.
In shaft (A Fig. 1) are slots (SS2 and S3). When shaft (A Fig. 1) is slid
through the bearings of the wheels into such a position that if either the wheels
or the shaft be caused to rotate the feathers (F, For F3, Fig. 1) in one of the
wheels are pressed into the slots (SS2 or S Fig. 1) any one of the wheels may
thereby be connected with shaft.
The feathers and the slots are so shaped that when shaft is drawn along through
bearings, the shaft (A Fig. 1) will press feathers (F, 12 or F3 Fig. 1) out of
slots (S1, S2 or S3 Fig. 1) thereby releasing clutches.
The wheel (W₁ Fig. 1) is shown connected with shaft, (A, Fig. 1). The
wheels (W and W Fig. 1) are shown with clutches released.
(Fig. 2, drawing with Provisional Specification shows three wheels in section
mounted upon a sleeve which is placed upon shaft should circumstances prevent
the sliding of shaft.)
Sleeve (L Fig. 2) can be slid along upon shaft A but cannot rotate independently
of it. On sleeve (L Fig. 2) wheels (W, W and W) can rotate independently
of shaft untill sleeve be slid into such a position that when either the shaft or
the wheels are caused to rotate, the feathers (F For F3 Fig. 2) in the recesses
or slots in bearings of one of the wheels (WW2 or W³ Fig. 2) are pressed by
the springs (for example P1, P2 or P3 Fig. 2) into the slots (S1, S2 or $3 Fig. 2)
in sleeve (L Fig. 2) thereby any one of the wheels may be connected with shaft.
The feathers (FF2 and Fig. 2) and the slots (S1 S2 S3 Fig. 2) are so shaped
that when sleeve (L Fig. 2) is slid along the sleeve will press the feathers (FT F
or Fig. 2) out of the slots (S' S2 or S Fig. 2) thereby releasing clutches.
There may be any number of such clutches to each gear wheel or pulley, and
any number of wheels or pulleys containing said clutches upon a shaft or sleeve.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
A novel means by which one or more than one loose gear wheel or pulley of any
type may be connected and disconnected with a shaft in the above described
manner.
