To all 'LlifLO/IL it may concern:

zlie it known that We, .VVILLIAM F. Booomi, a citizen of the United States,,resident of Bufi'alo, county of Erie, State of New York, and (Jami HAR'rMA- N, a subject of, the Emperor of Germany, and resident of Lancaster, county of Erie, State of New York, have'invented certain new and useful Improvements in Electric Regulators, of which vention may be applied tothe regulation of any circuit. \Vhile it is particularly. useful in the regulation of the voltage applied to a lamp circuit in car lighting systems, it may also be used to regulate the generator field current and in other situations. The various novel features and combinations will more clearly appear from the detailed description given below, taken in connection with the accompanying drawings. which form a part "of this specification.

In the drawings Figure 1 is a front eleva tion of a regulator embodying the improvements in one form, the right halt of the figure being largely in section; Fig, 2 is-an end elevation of the regulator of Fig. l, and F 3 is a diagram illustrating the regulator in series with the lamp circuit of an electrical system of distribution such as an aide driven car lighting system Referring to Figs. 1 and 2, 1 represents a suitable panel or base plate to which is attached two supporting tran' es 'by means of bolts 3. Carricd by and extending between the frames 2 are four rods 4, extending through and supporting tubularglassrods 5. which support and guide the carbon pile 6 composed of a series of carbon resistance disks or members. a

ii supporting rod or frame 7 is situated above the pile 6 and in proximity thereto, so that it Will be ailected by the heat of the pile \i. The rod 7 is provided with slots 8 through which. loosely pass screws 9 into extensions or the frame 2 so that the rod 7 is free .to slide longitudinally of the pile 6 on said extensions, being guided in such movement by the screws 9 in the slots Each end of the rod 7 is forked at 10 and in each forked end is pivoted a lever 11. Each lever 11 is connected respectively to an operating member or head .12 at each end of the pile 6 by means of two links 13 and suitable pivot pins, the links being held in place by means i of double U-shaped straps 14:, secured together'in the center between the two links by means of a volt 15.

The lower-end of each lever 11 carries an antitriction roller 16, adapted to be engaged by they head 17 of a screw adjustably secured in the upper end of a lever 18. The levers 18 are respectively pivoted in the opposite forked endsof a supporting rod or frame 19,

slidably mounted longitudinally of the pile 6 in brackets on the frames? and guided in such movement by screws 20 passing throughsuitable slots in the rod 19 and into the frames 2. The rod 19 is sufiiciently close to the pile *6, so that it expands, due to the heat therefrom. Flat springs 21, secured respectively to the levers '11 by screws 22, have their ends bear against the frames 2 and tend to keep the rollers 16 in engagement with the heads 1'? and. take up backlash.

Pivotally connected respectively to the lower ends of the levers 18' are links 23, the downward motion of said links :23 being limited by arms 23', the other ends 0% the links 23 being both pivotally connected to the stem 24 of a core or plunger operated by an electromagnetic solenoid 2b. The solenoid is provided With a surrounding magnetic structure 2? and graphite rings ing means for the stem 2% and core 25. the magnetic structure 27 being secured to the base plate 1 by screws Thesolenoid structure also includes a dashpot 29 haring a dashing mechanism consisting or a piston 30, iaving'an internal cylinder 31 rigid therewith and through the upper end of which extends a stem 32, rigid With the core The stem 32 has a head stirs lower end which is normally pressed aerinst a seat in the lower end oi? as cylind ber 23 by means of a spring: Tue lower end of the dashpot is provided with an out let closed by a set screw 3st. Two adjustable -18, which in turn actuate the levers ll and iro 'nls enriched to the head tl c n hi i3 c ctl H i i 28, which serve as anti-friction guidsolenoid as the pile expanded if at the same relative movement of the core to 'oper ate the operating members at each end of the pile l3 materially alters the magnetic pull on the core or arr iture :25, whereby, as the core is attracted the magnetic pull is materially increased with material increase in the magnetic turns of the solenoid. Thus as the opposing action of the springs increase due to their becoming stretched, the

magnetic pull correspondingly increases, so,

that with a given voltage applied the apparatus will be maintained in equilibrium with the core in various positions. This makes the apparatus extremely sensitive. By the inter-connecting of the operating parts at each end of the pile, through the rods 7 and 19, all of the working strains are taken by the active parts or the regulator instead of through the base 1. By placing the rods 7 and 19 so that they are affected by the heat of the pile 6 they have a tendency to expand and contract with the pile 6 and thus compensate for the eficct of temperature on the regulator which would cause a greater displacement of the core 25 in the time the rods 7 and 19 did not expand so as to more or less correspondingly separate the pivot points of the lovers 11 and 18. T his compensation is permitted by the slotted and sliding arrangement of the rods 7 and 19. which permits them to move freely longitudinally of the pile 6. This arrangement also permits the pile 6 and operating mechanism to adjust themselves laterally, so that there will be no binding between the plunger 25 and stem 2st and their bearings. "lhus either one or both of the screws having their heads 17 may be adjusted without throwing the core 25 out of alinement, as the pile G and operating mechanism at each end will shift to maintain the core in proper alinement. V

lietcrring to Fig. 3, represents a generator adapted to charge a battery ell and supply lamps or other translating devices l2. The regulator is shown with the carbon pile 6 connected in series between the battery and lamps and the solenoid coil "26 connectcd across the lamp circuit, so that any tendency for the voltage across the lamp circuit to vary, due to variations in voltage across the battery, is corrected by the regu-' i Boreas later, which ac to var the resistance in circuitwith the lamps, so as to maintain the voltage across the lamps substantially constant, as wi l be clear to those skilled in art. It will be obvious thrthmany changes and 'modificationsmay be made and the invention embodied in radically different forms.
