2 O 15 UNITED STATES PATENT OFFICE. THOMAs w. VARLEY, of PITTSBURGES, PENNSYLVANIA, ASSIGNOR. To WESTINGHouse ELECTRIC AND MANUFACTURING COMPANY, A CORPORATION OF PENNSYLVANIA. ELECTRICAL MEASURING INSTRUMENT. 1,181,2. Specification of Letters Patent, Patented May 2, Application filed March, i91. Serial No. 615,3. To all whom it may concern. 6 illustrates a modification of the armature Be it known that I, THOMAs W. WARLEY, Cup and Winding.

In the drawings, Figure 1 is a front eleva tion, partly in section and partly diagram matic, of a structure designed to be used as a watt hour meter. Fig. 2 is a transverse sectional view along the line A-B of Fig.1. Fig. 3 is a perspective view showing the pole faces on one side of the magnet, other parts being renoved or broken away. Fig. 4 is a diagrammatic view illustrating the connec tions. Fig. 5 is a detail view of the arma ture cup showing one form of winding. Fig. non-magnetic material, that serves to sup port a core 15 of magnetic material 16 is a Screw in the bottom of tube 14 that 85 constitutes a support for a shaft 17 having suitable bearings-only one of which is shown--and carrying the armature cup 18; vertical or longitudinal adjustment of the armature with respect to the field poles be 90 ing effected by means of the screw. Shaft 17 also carries the commutator member 19 to coöperate with brushes, 21, and a pinion 22 to drive any suitable indicating or registering mechanism (not shown). 23 indicates the armature winding carried by armature cup 18, the winding and cup, together, constituting the movable element.

One of the functions of winding. In Fig. 5, the winding is shown the auxiliary potential coils is to produce as extending downward vertically for ap and maintain a difference of magneto no proximately one half of the armature length, tive force between the two faces of each mag then circumferentially to a point diametri net pole. In maintaining this magnetomo cally opposite, then downward vertically the tive force difference the number of turns in length of the remainder of the armature, the auxiliary potential coils on one magnet then circumferentially on the same side of pole may be so proportioned that they more the armature, as before, to a point diamet than overcome the effects of the residual rically opposite, then upward vertically ap magnetism in that pole due to the load coils, proximately one half of the armature and the auxiliary potential coils on the other length, then circumferentially again on the magnet pole may be so proportioned that same side of the armature to a point diamet they assist the residual magnetism. How rically opposite, then vertically upward the ever, the coils that more than overcome the length of the remainder of the armature, residual magnetism may be of such number again circumferentially still on the same of turns as to neutralize the torque due to side of the armature back to the starting the residual magnetism. Thus it will be point, and so on, thus producing a double seen that the auxiliary coils may retard the armature. armature to overcome the torque of the ar In Fig. 6, the winding of the armature is mature due to residual magnetism. While diagonally downward to a point diametri the auxiliary coils are primarily for the pur cally opposite at the other end of the arma pose of maintaining a difference of magneto ture, thence circumferentially on the same motive force and thus actually retard the side of the armature at a point diametrically armature an amount proportional to the opposite and at the same end of the arma torque due to the residual magnetism these ture, thence diagonally upward again on coils may be utilized to give a slight result the same side of the armature to a point ant torque to the armature to overcome in diametrically opposite to the point of be itial friction, this being done by causing the ginning, and thence, still on the same side torques resulting from the use of the sta of the armature to the starting point, and tionary potential coils, on opposite sides of so on until the winding is completed. The the armature to be unbalanced. This result armature winding is thus to set up ant torque is, of course, proportional to the transverse magnetic fields that are reversed square of the potential. Another auxiliary as to polarity near the opposite ends of the resultant torque may also be exerted upon armature. the armature to compensate, either alone or The oneration of the apparatus is as fol in conjunction with the aforesaid means, for lows: If no currents flow in the load wind friction, this torque being caused by adjust ings 11 and 12, the currents in the armature ing the armature longitudinally in order to winding, in conjunction with the undis vary the relative positions of the movable torted lines of force of the constant field, and stationary windings. For instance, the produce substantially equal and opposing lower portion of the armature winding may torques upon opposite ends of the armature, be brought partially into the influence of

4 5 O 5 the upper polar faces of the magnet. This auxiliary torque is substantially proportional to the potential. By causing the auxiliary torque thus produced at a given load to be substantially equal and opposite to the re tardation due to friction plus a retarding torque due to the stationary potential coils, which may be produced, as hereinbefore set forth, by slightly unbalancing the torques exerted upon opposite sides of the armature due to said coil, unusually good results are obtainable and the meter will have a ligh de gree of accuracy with variations of poten...tial. The different windings of potential and load are arranged so as to neither add to nor decrease the total field of the constant mag net, so that the armature cup rotates in a constant field regardless of the shifting ef fects, and in consequence, the retarding torque varies as the speed, the whole instru ment acting as a Watt hour meter. By reason of the fact that the armature is of the two-pole type and the field is also two-pole, there is no tendency for side thrust upon the shaft and bearings, which is an important advantage of the present meter. To adjust for balance and to compensate for initial friction, the upper portion of the two parts of the core 15 may be elliptically shaped, while the lower portion of the two parts of the core may also be in the shape of an ellipse of the same dimensions as the upper one but with its long axis at right an gles to the long axis of the upper one, so that by turning the core, including both parts, any desired adjustment of the upper and lower air gaps relative to each other can be had. This is the equivalent of lon gitudinally adjusting the armature. A plan view of a core as thus constructed is shown in Fig. 7. Although as shown, the load winding is placed on the magnet poles and the main potential winding is on the armature, it should be understood that it may often be desirable to reverse the locations of these Windings, in which case the auxiliary poten tial winding is preferably dispensed with and the requisite amount of potential cur rent is sent through the load winding on the armature by any suitable arrangement of connections, as shown in Fig. 8. It is, obvious that the armature may be divided and one part balanced against the other, making virtually two armatures, al though electrically, when connected in the same circuit, they would constitute but one. I claim as my invention: 1.
