MAGNETO-ELECTRIC POCKET LAMP.
Application filed August 26, 1924. Serial No. 734,297.
rIhis invention has for its object a magneto-electric pocket lamp provided with a tubular protectingcasing within which is securely mounted an inducting magnet adapted to be actuated by a driving gear and having iixed therein an inductor, the features oi' novelty in this apparatus consisting therein, that one of the axles or shafts axially arranged to and connected with either end of the inductor serving for the production of the electric current is securely mounted in the closed end oit the `tubular casing, while on the opposite end of the inductor the second centre axle or shaft is bolted to a casing containing the driving gear. In this way a connection between the inductor and the electric lamp is effected by means of a contact pin, the latter' being iixed in an insulating sleeve mounted in the. second of the aforesaid axial shafts and, with one end of the anchor winding, being guided through a bore provided in the last named shaft. Simultaneously with this operation an insulating contact device arranged in the driving gear casing is caused to make connection with the electric lamp of the inner electric circuit, while the outer circuit is led over the protecting casing. Further novel features consist in that the driving gear casing, which comprises several parts, is held together by means of two screw-bolts, ot which one is at the same time clamping a spring having the tendency to raise the bar of a rack from the driving gear casing and make it engage with a pinion of the driving gear. The latter possesses a couplingcomprising two coupling-wheels of which one is spring-controlled and made to engage with the other when the apparatus is actuated. One of the coupling-wheels is furthermore meshing with a gear wheel which by means of intermediate gear'wheels transmits its movement to a toothed wheel mounted with its flanged part in a flange attached to the magnet. Owing to the screwing together of the several parts of the casing containing the driving gear by the aid ot the screw-bolts the said gear is guided by and bearing in the casing and prevented from displacement in an axial direction.

Referring to these drawings, l designates av tubular protecting casing ot which one end is closed while into the other end, the socalled lamp-head 2, the electric lamp 3 is screwed. 4t is a check lever by means of which toothed bar 34 adapted to actuate the driving gear is stopped trom movement when the apparatus is not used. For the manipulation of the bar 534i a knob 5 is screwed into the same. n p
Y The closed end oi the protecting casing l is of a suitable thickness and strengthiin order to receive and securely hold in a cylindrical recess therein an inductor shaft 6 of which one end extends through a bore in the head part ot a magnet l5 which, longitudinally, is of U-shaped section, the other end :iii
of the shaft 6 carrying a disk 12. There is also a central axially disposed shaft 7 mounted at the other end ot' the inductor, this shaft carrying a disk 8 and being hollow and at the right hand end provided with screw-threads,Fig. 3. Leading throughthe hollow shaft 7 is an electric conductor which is disposed within an insulating sleeve 9 and connected with a contact pin 10, saidj conductor also extending through another insulating sleeve 46 fitting into the bore of the sha'tt 7. The disks 12 and 3 are in connection with the'inductorll which seen in cross section has double T-Orm, Fig. 5. TWound around the iron core 11 is the wiring 13 which with the core `forms the inductor.
The U-shaped magnet is rotatably mounted upon the inductor and, by means of a sleeve 13 secured on the shaft 6, journaled thereon. Attached to the open end of the magnet, that is, to the ends of thetwo parallel members of the same, by screws 17, is a guiding flange 16, in such a manner, that the magnet 15 with the said flange is also rotatable on the shat't 7. Between the outer end of the inducting magnet 15l and the protecting casing 1 a small space for play is provided. The guiding iange 16 is formed with a nave which carries a toothed wheel 19 adaptedl to rotate on the shaft 7.
The inductor is connected by bolts with a casing containing the driving gear and con-- sis'ting of the tour parts 20, 21, 22, and 23, Figs. 2 and 3, which are secured to each other and to the protecting casing 1 by the screw-bolts 33 and 37. Ot these parts that denoted by 21 contains an insulating sleeve 24 in the one recess of which a` set-screw 25 is arranged and made to securely hold a rightangle shaped contact plate 26. The screw 25 engages with, that is, it is screwed into a nut situated within a second recess in the sleeve 24, which nut 27, by means of aspring 28 is in electrical connection with the contact pin 10. The contact plate 26 is connected with a contact blade 3() fixed upon and extending into the insulating disk 23, Fig; 4, and thus forms the electrical connection from the inductor 11 to the electric lamp 3. The Contact blade 30 is hereby held fast on the insulating disk 23 by a set-screw 31. One pole of the winding 13 is therefore connected with the one contact of the electric lamp by the members 25, 26, 27 and 30, whereas the other pole of the winding, for instance for an insulating protecting casing, is in electrical connection with the other contact of the electric lamp by means of the parts 11, 3, 7, 21 and the bolt 33, which also secures a contact blade 32 on the insulating disk 23.
The holding fast in position ot the toothed bar 34, as already mentioned, is eected by means ot the checking lever 4 which is pivotally mounted" in the casing 1 and provided position shown in Fig. 14 into that illustrated. in Fig. 15, Eni the position shown in Figs. 13 and 14 the bar 14 is stopped from movenient in the casing. By swinging the checking lever about an angle of 13()O the toothed bar is rendered tree, owing to the recess 4T Abeing brought into the sliding plancof the The driving movement takes place in the ollowing nia-nner. T'lieiniddle portion ot van axle or shaft 14, which forms an integral part with theY toothed wheel 40, is ot square Isection and arries an axially slidably coupling wheel 42 kept in engagement withv the wheel 41 by the spring 43, the wheel 41 being freely and* rotatably mounted upon the right-hand cylindrical portion ot' the shaft 14. The toothed wheel 41 engages with a gear wheel 39, Fig. 11V, which is rigidly connected' with another gear wheel 38, the latter rotating the toothed wheel 19 and with it the magnet. rlhe toothed bar 34, which is capable of upward and dowi'iward movement, engages with thev toothed wheel 40. Upon the projecting end of the said bar a handle 5 is screwed.
W'hen the toot-hed: wheel 40 is turned during the downward' movement ol' the bar 34, the coupling' wheel 42 will' cause the rotation ofthe wheel" 41. lt, however, the wheel 42 vis rotated in the opposite direction, which i's thecase when the toothed bar is moved upwards, the wheel 42 only, rotates, because the bevelled faces of the teeth of the wheels 41 and 42 slide away over each other so tha t the magnet is in no way hindered in its rotation. Part of the coupling wheel is formed as gear wheel. The pinion 39 is cary ried by a sleeve 44 lined in the disk 2l and is connected with the gear wheel 33. Both whe-els 33 and 39' are journaled in and guided by the disk 20. y
rl`he toothed bar 34, which has lined to it a pin extends through a slot provided in the disk 22, is under the control of a spring1 36, Fig. 9, which preferably consists of two or three thin steel blades mounted one upon the other. One end ot this spring is secured to the pin of the toothed bar and the other end' to one ot the screw-bolts 33, with theeii'ect that the toothed bar has the tendency to move upwardly.
When used the apparatus works as tollows: Assuming the toothed bar 34 to be moved downwardly by the handle 5, the toothed wheel is made to rotate and,
through the medium of the aforementioned gear wheels a rotation of the inducting magnet caused, so that inducting `electric currents are produced which bring about the lighting of the lamp. The spring 36 then causes the toothed bar at once to move upwards again into the former position whereupon the bar is pressed down once more byhand in order to impart a new impulse to the rotary movement of the magnet l5. The actuation of the toothed bar is continued as long as the supply of light is desired.
