MAGNETO GENERATOR.
To all whomz't may concern:
Be it known that we, ADoLPH HARRY RAILIN and ARTHUR ERNEST ANooLn, citizens of the'United Kingdom of Great Britaim and Ireland, and both residents of 67 Queen Victoria Street, London, E. C. 4, England, have invented certain new and useful Improvements in Magneto Generators, of which the following 1s a specification,
such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in hand operated magneto generators suitable for hand lamps, as lighting and analogous purposes and re ers to that type of apparatus in which a hand operated magnetogenerator is employed to furnish current to v the lamp, sparking gear or other device.
The chief object of the invention is to facilitate manufacture, and by the special construction and arrangement of the parts of the apparatus, and at the same time to keep the overall dimensions at a minimum.
The chief feature of the invention is the arrangement of the permanent magnet system and with this a novel method of connecting the operating handle, and, in the case of electric lamps includes an improved method of mounting of the lamp by all of which a most efiicient apparatus of small dimensions is obtained.
In carrying out/our invention the machine is kept asthin as possible so as to be convenient for carrying in the pocket, and to reduce the overall length a special arrangement of the ma etic circuit enables the lamp cap and bul to be sunk into the body of the machine.
Methods of carrying out our invention and details of parts are shown in the accompanying drawings in which- Fig. 1 is a view'of the apparatus as applied to a lamp, with one side removed and a small 'part' in section. This drawing shows the operating handle in closed position.
Fig. 2 shows a similar lamp but on substantlally a vertical section to that shown in i 3 is a broken elevation of one of the meta .side plates. a
Fig. 4 is a transverse section showing the edges of the side plates seated in the recesses of the magnets. I
F i hand e.
Fig. 6 is a transverse section thereof.
Fig. 7 is a perspective view of the free'end of the handle showing the same constructed of sheet metal.
Fig. 8 shows how the invention could be fitted with a spark gap and used for gas 1i hting purposes.
11 Figs. 1 to 7 the magnetic circuit consists-of two flat strips of metal a, a bent to form the poles a'-, a of the magnet between which rotates an ordinary H armature b. The strips are magnetically joined by 'a yoke c of soft iron of sufiicient cross section to permit of it being bored out at 0' and threaded to receive the lamp cap d, the bulb d of the lamp being also sunk in a recess in the yoke. Y
The 0 crating handle e works in connection wit a toothed quadrant f to drive a 5 is an elevation of the operating series of wheels geared to the armature, one
of which is fitted with pawl and ratchet to enable the armature to continue running between the strokes of the handle, the whole of the mechanism being suitably carried by two metal plates g, g which are connected together at one end by the aforesaid iron yoke c and the other, viz: the armature end, by a non-magnetic block is and cross pillars Z, l at suitable positions between the two blocks, all in substantially ordinary clockwork manner. Thus the gearing, including the armature, is mounted between the two plates g, g. The plates are shaped at one end so that their edges 9, 9 (Figs. 3 and 4) are concentric with the armature, and the two permanent magnets are clamped on after the wheels and armature have been erected between lates. This enables all the -fitting work an mechanical testing to be done before it is closed in by the addition of the magnets. At the same time the shaping of the plates concentric with the armature ensures that when the magnets are clamped on they are held in the correct position in relation to the armature so as to maintain'the correct air 'gaps between the armature and the permanent magnets. It will be seen in Fig.4 that the edges of the magnets are recessedto receive the edges g and g of metal plates g, g.
The special detail in the connection of the operating handle or lever e to the toothed quadrant fis that the latter is provided closely in both arms of the U. This 'arrangement is simple to erect and as the spindles are put a fair distance apart, say
from g" to 7}, power is easily transmitted to the toothed quadrant.
The operating handle e preferably made out of sheet metal is bent in 'U shape form to embrace the machine from back to front and is also extended down the side of the machine so that the fingers can operate it easily.
For the purpose of preventing the operating handle nipping any part of the hand as it approaches the outside of the machine, the part on which the fingers press is shaped so that the outer edges stand further away from the machine than the centre. This means that the centre of the lever touches the outside of the magnet first whilst the outer edges are still, say i" away from the magnet. This cross section of the lever extension also gives considerable strength and enables us to make it out of relatively thin and light material.
In Fig. 8 thetop of the apparatus is shown and has fitted to it a sparking device in place of the lamp. This device comprises the terminals or points 1' and s insulated by the block t and with a spark (gap u. A perforated guard may be provi ed as shown by dotted lines. The points could be in a tube or other fitting attached to the apparatus or otherwise conveniently arranged.
What we claim and desire to secure by Letters Patent is:
A hand operated magneto generator, comprising a casing having end walls of plates forming a magnetic circuit, each of said plates being shaped at one end to form magnetic poles, an armature mounted for rotation between such poles, a yoke of soft iron connecting said end walls remote from the armature, said yoke being formed to support the means to be influenced by the current generated, an operating means mounted between said walls above the armature, side walls having their edges seated in receses in the end walls, means for securin 'the end walls together to thereby fix the side walls in place, and driving mechanism between the operating means and armature.
In witness whereof we have hereunto set our hands in resenoe of two witnesses.
