Beit known that-I, LEWIS L. TA'roM, citizen of the United States, residing at Norwood, in the county of Hamilton and State,
of Ohio,'have invented certain new and use ful Improvements in'Oontrollers', of which I the following is a-full, clear, and exactspeck fication.
controllersfor electric motors.
The" object of my invention is to so con: struct amultiple-voltage controller thatthe (lifl'erent mains may be connected to the armature as desired, that there'may-be a vari; able resistance for the'field circuit, land-if de-- sired-also o'neJfor the armature circuit, and
that these resistances'may both be governed by the controllerwithout requiring the con- Y troller drum to be of an undue length.
In one aspect .my" invention comprises a multiple-voltage controller consisting of a rotatabledrum controlling theconnection of the armature 'to the different mainsof {the system, and a lever movable by the drum for In. a more s ecificcaspect my nvention comprises a mu ti'ple-voltage controller con: sisting of a rotatable drum," contact fingers cooperating"therewithand so arranged that-- as the drum is rotated the armatureisconnected' acrossma'ins' of-ldiffe'rent voltages and aresistance in the armature circuit is varied,
a resistance in the field-circuit, and a star ranged to move said lever as the tated..,
' Other features of my invention will appear from'the description and drawings and will be-specifically set forth int-he claims. Figure lfis 'a plan view' of my controller with the top cover removed. Fig. 2 is, an end View of the fieldresistance and. the lever for varying it, 'Fig. 3 is afront'elevation-ofj the upper part of the controller, with the front-casing removed. Fi LA; is a diagram showing theconnections o a controller embodying my invention. 1
I The controller drum isrepresented by 1 and is mounted on a shaft 2. Thi's drum-1's-rotatable bythe usual handle 3. On the .shaft'2 is a notch plate 4, with the peripheryxof which a V notch There is but a small distance between succes- -mains, buta greater .mature'from one set 8, on the periphery mounted on al'ever 1.0.

siv'e notches ,in' the same set.,ithus causing a comparatively small movement of the :drum' while passing betweendifferentpoints when the armature is connected to the same set of 7 between successive e connections of the arv of mains to another.' p [Also mounted on the shaft 2,is astar wheel controller changes th The lever110 is 11 (listanceand large-horns sets of notches, thus re-;
iquiring a much lar 'er movement when the which ridesa roller 9,
ported inany desired-manner, as from t e controller covenand iss ring-pressed toward y reason of the. en-
s finger-11" passes "between and engages] the sets of contacts 12Iand113 ,and as'it is out the field resistance sections- 14 and 15, which are connected with I the contacts 1 2 The resistances 14 and .15 are varied alternately,
Thus the field resistances moved by the rotation. of the drum, cutsin or i because-the two halves of: finger 11 are ofls'et from each'other, as shown plainly-in Fig, 2. 1 -14 and l5"-are cut in or outin four steps; I
This number of steps may bevaried as de sired by increasing the number of sections in resistances 14 alnd'15and increasing the number of contacts Hand 13 correspondingly;
-,The contact" fingers .16 to 25--inclusive- 1cooperatewith the contacts on drum 1, the con vta'cts 16 and c5 beingconnected'to two terminals ofthe motor armature 31, the contacts 21 to 25 inclusive being connected" to different points on the armature resistance 26 and the'contacts 17 to 20 being connected respectively to the different mains 27- to 30 respectively Between each 'p'air of adj acent majnsthere is a difierent voltage, ar-
multipleevoltage system; The field 3 2 ofthe motor ifsconn'ected between the outside. mains 27 and 3.0 andin series with the resistances '14 andlfi.
the parts are as-shown in'full'lines'in Fi 1': When the controller I is movedif into I ita- ,l t T operative position a}, thewlever-'IOL-ismOYBd into thev position shownin dotted lines in. Fig. 1, and the field resistances 14 and 15' are entirely out out, while the armature 31 is connected acrossthe mains 27 and'28 with the full armature resistance 26in serieswith it. Asthe drum is moved forward to position a the armature resistance is out out step by step, the field resistances during this time remaining unchanged because between positions a and a there is no eccentricity in thestar wheel 8. As the controller is moved,
between positions at and a, the field resist substitutions may be made in the articular ances 14 and 15 are gradually 'cut into thecircuit, thus decreasing the field strength of the motor and increasing its speed. When the controller is moved mto position b the,
pressed on it, and at the-same time the field resistances are-cut out of circuit. As the controller is moved forward to position b, the field resistances are gradually .cut into circuit, thus again weakenmg the motor field. The same'series of operations of simultaneously connecting the motoracross mainsof' a higher voltage and simultaneously cutting out the field resistances and then gradually cutting insaid fieldresistances, again takes place as the-controller is moved-to and through each of the other sets of positions 0 too, d to d 6 to e andf tof These positions are marked in Fig. 1 for both the notch-plate 4' and the star wheel 8, and in Fig. tfor thedrum. I With the controller arranged as shown the armature resistance is not. used savewhen the controller is connected to the lowest voltage,,but fit. is obvious that if desired this ar-. mature resistance may be'use'd at any or every set of positions. The field circuit of the motor isnever broken by the controller.
but is arranged to' be broken when the switch 33 is opened, this switch 33 entirely isconnecting the controller and the motor. In the controller shown the field resistances are cut in and-out completely at each set of positions, but obviously either the cutting in or out maybe only-partial at any set ofpositions if such a construction is desired. -1
Itis obvious'that many modifications and arrangement whleh I'have here s own and described, Without departing from the broad spirit and scope of my invention, and in, the following clanns I aim to cover broadly the new combinations invented by me.
