COMPLETE SPECIFICATION. Lighting Device for use in Shaving

591,515

I, Jack Klaw, a British subject, of 38, Ridge Road, Stroud Green, London, N.8, do hereby declare the nature of this Invention and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement :—

This invention relates to a lighting device for use in shaving, the invention being concerned with a device of the kind comprising a holder for an electric lamp bulb, the holder having means for connecting it to the handle of a safety razor so that a beam of light from the lamp can be concentrated on the face in the locality of the cutting edge of the razor when the latter is used in shaving.

The device according to the invention comprises a stem having at one end a socket extending at right angles to the stem for the reception of an electric lamp bulb, and provided with a spring clip for engagement with the handle of a safety razor which includes a shaving head, the stem being of such length and the clip being so positioned relatively to the lamp bulb socket so that when the clip is engaged with the razor handle, the lamp bulb socket will lie above and overhang the shaving head of the razor.

The lamp bulb can be of low voltage and amperage such as obtain with an ordinary pocket lamp bulb.

The source of electric current may be constituted by an ordinary pocket lamp battery and the battery may be accommodated in the stem if the latter is made hollow, or in a separate container attached to or separate from the stem. In the last mentioned event, the battery will be connected to the lamp bulb socket by means of a flexible electric conductor which, where the stem is hollow, can conveniently pass rough the latter.

As an alternative, current for the lamp bulb may be supplied from the ordinary electric A.C. mains through a suitable step-down transformer. In this case, there will be provided a flexible electric conductor, one end of which is connected or adapted to be connected to the lamp bulb socket, while the other end is provided with a plug or socket for connection to the transformer.

The circuit to the lamp bulb socket may include a switch for controlling the supply of current to the lamp bulb, the switch being located at any convenient point.

The stem and lamp bulb socket can be of any suitable material, rigid or flexible.

Preferably the lamp bulb socket is arranged in a recess accommodating the lamp bulb so that the latter does not project excessively from the holder and is afforded protection by the surrounding material against damage.

In order that the invention may be more readily understood, reference is now made to the accompanying drawings, in which :—

Figure 1 is a perspective view illustrating one embodiment of the device according to the invention as applied to a safety razor and connected to a source of electric current;

Figure 2 is a longitudinal sectional view of the device as applied to the razor, and

Figure 3 is a part-sectional, part-elevational view, giving details of a suitable socket arrangement for the lamp bulb.

As indicated in Figures 1 and 2, the illuminating device consists of a hollow cylindrical stem 1 provided at its upper and with a tapered socket 2 arranged at right-angles to the stem. The stem and socket are of any suitable material, synthetic resin for example, and are shown in the drawings as made in one piece, although it will be understood that they can be made as separate parts suitably joined together.

The opening 3 in the socket 2 is arranged at the wide end thereof and provides accommodation for an electric lamp bulb 4 having an order of voltage and amperage like that obtained with an ordinary electric pocket lamp bulb, the opening being so dimensioned that the bulb projects only partly therefrom so that it is largely protected by the surrounding material.

Current for the lamp bulb 4 is supplied through flexible leads 4 which extend from the bulb, through a bush 6 arranged within the stem 1, and are joined to a suitable source of electric current such as an ordinary pocket lamp battery 7.

The stem 1 is provided with a bifurcated spring clip 8 the arms 9 of which are adapted to be engaged round the handle 10 of a safety razor suchwise that the socket 2 with its lamp bulb 4 will lie above the rear part of the shaving head 11 of the razor and, when illuminated, will shed light on to the face over the cutting edge 12 of the razor blade 13 when the razor is in use.

The arms 9 of the-spring clip 8 have frictional engagement with the razor handle 10, so that by sliding the clip along the handle, the position of the lamp bulb 4 above the shaving head can be adjusted to a nicety.

The spring clip 8 may be secured permanently to the stem 1 of the lighting device or may be slidable along it so as to provide greater range for adjustment of the lamp bulb. In the latter case the part of the clip engaged with the stem 1 may be bifurcated so as to have gripping arms like the arms 9.

Figure 3 indicates to an enlarged scale how the socket 2 may be constructed to take an ordinary pocket lamp bulb (indicated by the broken lines 4) having a screw-threaded metal shank forming one of the contacts, the other contact being provided by a metal projection at the end of the shank. In this case the stem 1 and socket 2 are made separately from each other and are suitably joined together. The socket 2 accommodates a screw-threaded metal ferrule 14 which forms a terminal for one of the current supply leads 5 and into which the shank of the ferrule is perforated to receive a screw 15 which forms a terminal for the other current supply lead, the contact at the end of the shank of the lamp bulb being adapted to engage with the screw when the bulb is screwed fully into the ferrule. The terminal screw is electrically insulated from the ferrule by means of washers 16 of insulating material, and is held in place by means of a nut 17 which also serves to join one of the leads 5 to the screw.

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 :—

1. A lighting device for use with a safety razor, the device comprising a stem having at one end a socket extending at right-angles to the stem for the reception of an electric lamp bulb, and provided with a spring clip for engagement with the handle of a safety razor which includes a shaving head, the stem being of such length and the clip being so positioned relatively to the lamp bulb socket that when the clip is engaged with the razor handle, the socket will lie above and overhang the shaving head of the razor.

2. A device according to Claim 1, wherein the lamp bulb is of low voltage and amperage such as obtain with an ordinary pocket lamp bulb.

3. A device according to Claim 2, wherein the source of current is constituted by an ordinary pocket lamp battery.

4. A device according to Claim 3, wherein the battery is accommodated in the stem which is made hollow for the purpose.

5. A device according to Claim 3, wherein the battery is accommodated in a separate container attached to or separate from the stem.

6. A device according to the last part of Claim 5, wherein the battery is connected to the lamp bulb socket by means of a flexible electric conductor.

7. A device according to Claim 2, wherein current for the lamp bulb is supplied from the ordinary electric A.C. mains through a suitable step-down transformer.

8. A device according to Claim 7, wherein there is provided a flexible electric conductor, one end of which is connected or adapted to be connected to the lamp bulb socket, while the other end is provided with a plug or socket for connection to the transformer.

9. A device according to any of the preceding claims, wherein the opening in the lamp bulb socket is so dimensioned that the bulb projects only partly therefrom.

10. A lighting device for use with a safety razor, the said device having its parts constructed, arranged and adapted to operate as hereinbefore described with reference to the accompanying drawings.
