Abstract

A clock has a movement (1) having a case (2) from which nested concentric drive shafts (3) protrude. A front housing member has a wall (7) formed with an aperture (10). A planar dial (11) rests against the wall (7) and is formed with an aperture (12) in register with the aperture (10). A rear housing member (6) co-operates with a front housing member (7) to form the clock housing and is formed with a forwardly projecting recess (15). The clock movement (2) rests against the base of the recess (15) and is positioned within the recess (15). The base of the recess (15) is formed with an aperture (16) in register with the apertures (10, 12). A nut (18) engages the front face of the dial (11), extends through the aligned apertures (12, 10, 16) and engages the casing of the clock movement (2) thereby holding the dial (11), the wall (7), the base of the recess (15) and the clock movement (2) in position. <IMAGE>

Description

SPECIFICATION A clock This invention relates to clocks.

According to this invention, there is provided a clock comprising a clock movement having a case with protruding nested drive shafts, a front housing member having a wall formed with an aperture, a planar dial which rests against the wall of the front housing member and is formed with an aperture in register with the aperture of the wall, a rear housing member which co-operatesthefront housing memberto form the clock housing and is formed with a forwardly projecting recess, the clock movement resting against the base ofthe recess and being positioned within the recess, the base of the recess being formed with an aperture in registerwith the apertures in said wall and the dial, and a securing device which engages the front face of the dial, extends through the aligned apertures and engages a fixed member ofthe clock movement thereby hol- ding the dial, the wall, the base of the recess and the clock movement in position.

Preferably, the securing device is a nut having a male thread which engages a female thread of a fixed member of the movement; the fixed member of the movement is preferably its case.

An embodiment of thins invention will now be described, by way of example only, with the reference to the accompanying drawings of which: Figure 1 is an exploded view of a clock in accord ancewiththisinvention; and Figure 2 is a section through an assembled clock in accordance with this invention.

Referring now to the figures, the clock has a movement 1 having a casing 2 from which nested concentricshafts 3 protrude. The casing 2 also has at its upper end an upwardly projecting hook4usedfor suspending the clock on awall hookornail.

A clock case is in the form of a front casing member 5 and a rear casing member 6; front casing member has a circularflatwall 7 rearwardly offset from an annular ridge 8. The front casing member5 also includes a skirt 9which extends rearwardlyfrom the ridge 8which is semi-circular in cross section as can be seen in Figure 2. The wall 7 has a central aperture and has resting against it a dial 11 with an aperture 12 in alignment with the aperture 10. The dial 11 may be printed on both sides.

The rear casing member 6 has a rearwall 1 3from which a circular rim 14 extends forwardly and also has a forwardly extending recess 15 at its centre. The recess 15 has an aperture 16 in the middle of its base and in alignmentwith the apertures 10 and 12.

As assembled (see Figure 2), the clock movement 1 isfitted insidethe recess 15 and rests againstthe sur- face of the base of the recess 15 with the aligned concentric shafts 3 protruding through the aligned aperture 16,10 and 12. The base of the recess 15 rests againstthe rearsurface ofthewall 7. The rim 14fits within the rear end of the skirt 9 and its front end rests against the shoulder 17 formed within the skirt 9.

A nut 18, which has a central bore 1through which the shafts 3 pass, extends through the aligned apertures 12,10 and 16 and is screwed into a female thread in the casing 2 thereby clamping the dial 12 againstthewall 7,thewall 7 againstthe base ofthe recess 15 and the base ofthe recess 15 againstthe casing 2.

Hour and minute hand 20 and 21 are mounted on the concentric shafts 3 in the conventional manner.

It will be seen from Figure 2 that hook 4 is located within the upper end of the recess 15 with a certain amount of access around itto enable the hook4to be utilized to suspend the clock from a hook or nail in a wall.
