1 Claim. (Cl. 2550-1) The invention is in the class of motors in tongue 3 extends rearwardly, the forward end of which mechanical movement is maintained by said tongue being finally secured to said diathe discharge of a liquid or Vaporous iluid against phragrn which serves as a spring support for a movable machine element, and is more spesame.

Said vane forms a horizontal keel 'l Said primary and secondary impacts, and the across its interior, said keel normally facing the normal vibratory period of the part being in nozzle 4 and said keel being in the discharge synchronism with the time of fluid travel bepath 0f Said 1102218- tween said impacts; and the invention consists The keel 'l iS OImed 'DY the junction 0f the 15 substantially in the construction, combination, oppositely curved upper deflector 8 and lower and arrangement of the features hereinafter defieetor 9, the upper deector 8 curving forpointed out and recited more particularly in the wardly and upwardly into continuation with the claims. upper vertical iloor section IIJ of the vane 6.

For this reason the total device. fluid pressure against one of said deflectors is Similar characters of reference designate simigreater than the other which causes the vane 6 50 lar parts throughout the different views. to swing in the opposite direction, the fluid then Referring to Fig. 1 the numeral I indicates a being directed by the one deilector to along vertical diaphragm type spring the edges of which the respective floor section I0 or II, and against are clamped to the frame 2, and from the centhe respective dam I3 which reverses the movetral portion of which the normally horizontal ment of said vane and starts the vibration of 65 same on the tongue 3, the spring I yielding and returning accordingly. Said vane is thus moved in the other direction until the other deflector is more exposed to the discharged fluid, which accelerates the movement of the vane in the same direction, said fluid then subsequently striking the respective dam I3, and starting movement of said vane in the direction i-lrst caused by the fluid striking more of the said one deilector, and the cycle of operation is again repeated, and alternately during operation.

On the opposite side of the spring I and jig saw yoke I l' is secured, and extends forwardly therefrom for operating the jig saw I8, through the saw table E9, by which arrangement it will be understood that said yoke is vibrated by the tongue 3 through said spring and that the said jig saw is operated by the action of the fluid discharged against the vane 6 as above described.

n order to influence the spring as to its independent vibratory inclination in adjusting the same to respond to the vibratory period coincident to that of the vane 6 acting under fluid discharged at a given pressure, an adjusting spring 28 is tensioned between the lower end of the saw yoke ll and a point forwardly thereof, the forward end of said adjusting spring being conveniently engaged by the hook bolt 2|, which extends through the forward supporting wall 22 of the saw table I9 to threaded engagement with the nut 23 which is on said bolt and can be adjusted thereon to vary the tension of said 'adjusting spring as desired. In this connection it should be noted that said adjusting spring is tensioned at an angle to the said yoke I'I and tongue 3 by which it will be understood that said adjusting spring is also used to normally inuence the spring I, to normally position the keel l slightly out of alignment with the medial line of the nozzle 4, through the tongue 3, to aid in initially starting the vibration of the vane 6 as above discussed.

The circular magnetic core 24 is rigidly suspended to the lower surface of the saw yoke Il, said core being curved approximately about the center of movement of said frame, the spring I and tongue 3. Said core is surrounded by the coil 25 and spaced therefrom, said coil being correspondingly curved. Said coil is nested in the correspondingly magnetic eld 26 which is mounted on the oor 2'I of the frame 2. It will be seen that the core 24 is oscillated in said coil by said saw yoke when vibrated as above described, and that electrical current is thus set up in said coil which serves to illuminate the ordinary light bulb 28 through the conductors 29 and ground connections 30, by which arrangement it will be understood that light current is thus generated for the operator using the saw I8.

Between the spring I and wall 5 the side walls 3| of the frame 2 form an enclosure for the vane B said spring and wall 5 closing opposite ends of said enclosure and forming therewith a nuid proof compartment which prevents the promiscuous scattering of fluid from said vane, the drain 32 being provided in the floor of said compartment for the escape of such fluid.

Referring to Fig. l the dotted lines 33 and dot-and-dash lines 34, indicate extreme opposite operating positions of the frame I'I, tongue 3 and vane 6.

While the description and drawings illustrate in a general way a certain structure which may be employed in carrying the invention into effect, it is evident that many modifications can be made in the various details without departing from the scope of the appended claim, it being understood that the invention is not restricted to the particular example shown.

The invention claimed is:

A iiuid velocity vibratory motor-operated generator which comprises, in combination, a fluid velocity vibratory motor, including stationary mountings and a vibrating diaphragm both made of magnetic material, a vibrating saw yoke, also made of magnetic material, coupled to and driven by said motor, a vibrating male permanent magnetic pole piece suitably attached to an under side of said saw yoke, and a stationary female opposite pole piece including a stationary coil of wire within a recessed portion, the eld of magnetic force which is produced by said male permanent magnetic pole piece including, in series, said male pole piece, said female pole piece, said stationary mountings, said diaphragm, and said saw yoke.
