Patented sept. 4, 190e.

Beit known that I, WILLIAM L. DOLIER, a citizen of the United States, residing at Phila` delphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Im rovements in Driving Mechanism for Centnfugals, of which the following is a s ecication.

Itis the o ject of my invention to provide an electric-motor drive for a centrifugal machine, the motor and centrifugal basket being adapted to gyrate together about a common omt of support; and it is particularly the object of my invention to gain a saving in vertical height or head room in the combined motor and centrifugal apparatus. To

close up Ato the hanger as possible, and the bracket for supporting the motor-field element extends upwardly beyond the hanger and is secured upon an inner spindle.

invention resides, further, in features hereinafter pointed out and claimed.

Reference is to be had to the accompanying drawings, in which- Figure 1 is a general view in elevation of the e ectric motor as applied to a centrifugal Fig. 2 is a vertical view, artly in section and partly in elevation, of tlie hanging device and the electric'motor. Fig. 3 is a side view of the bracket carrying the lower bearing ofthe motor. Fig. 4 is a plan view of the motor, showing the spindle and hollow shaft in section.

its bottom has a At 1 is represented any fixed body, such as a girder or tankffrcm which is hung the combined centrifugal and driving-motor. A b se member 2 is bolted to the under side of the ember 1, and to the base 2 is secured the hanger 3. This hanger 3 is hollow and at perforation forallowing the passage of the non-rotatable spindle 4 therethrough. This perforation is slightly larger in diameter' than the spindle 4 at this point to plermit gyratory movement of the spindle wit out engagementiwith the hanger 3. In thei'lower en of the hanger 3 is a spherical cavitgl lined with a surfaced mass of metal a, 'ch bears the spherical member 5. This member 5 has cut in it a vertical slot b, which embraces an extension c on the interior of the memberf. Member 5 is secured to spindle 4 andin consequence of the extension c said spindle is inca able of rotation. Because of considerable E ay between the slot b and the extension c t e spindle 4 and the member 5 A hanger 3. i To adjust member 6, it may be compressed to a greater portion ofthe shaft 14 is the armature-spider may, however, deflect or gyrate in any direction. Upon spindle 4 is mounted the motor and centrifugal, and it is about the member 5, therefore, that any deflectionof the centrifugal and motor takes place. As resilient means for opposing the deflection of the spindle 4 there is supplied a mass of rubber or like material 6, embracing the indle 4 and filling the upper end of the the resiliency of the or less extent between the washers 7 and 8. The lower washer 8 bears against a flange 9 on the spindle 4, and the upper washer 7 is held in any position desired by means of the washer 10 and set-screw 11.

The spindle 4 extends downwardly through the motor and Lust. beyond the centrifugal basket 1.2, whic revolves within the housing 13. i

14 is a-hollow shaft surrounding the spindle 4 and secured to the centrifugal basket 12 2,.

to drive th`e same. Mounted upon the upper 15, carrying the armature 16. It is t erefore by the armature 16 that the shaft 14 and the centrifugal basket 12 are driven.

The member 17 is secured at its lower extremity byscrew-threads to the shaft 14, and within the member 17 'is maintained a quan- .tity of lubricating-oil, which passes down between the spindle 4 and the linner surface of the shaft 14 and is drawn off at the bottom of the centrifugal. This oil may be introduced through the opening 18, which embraces the hanger 3. The surface 19 of the member l17 is employed for mechanical braking, a brake-strap 20 being drawn against the surface y19 by the lever 21, controlled by the handle 22.

As seen in Fig. 2, the arrangement of the brake-Wheel and lubricator is such that the armature of the motor is brought as close as may be to the hanger 3, thus economizing space and reducing the dimensions of the entire apparatus.

. The motor herein shown is of the mltipolar type, whose field-ring or yoke is shown at 23 and whose poles are shown at' 24. Upon each pole is a shunt-winding 25 and a series winding 26. The field-ring 23 is secured in the bracket 27, extending upwardly and be ond the hanger 3. y The upper extension of the spindle 4 enters #the center of bracket.27 and is keyed to said bracket to prevent any relative motion. '27 is a cen- IOO IVO

tering-screw by means of which the field is properly -adjusted with respect to the armature. From this structure itis apparent that the field-ring 23 is supported by bracket 27 and by means of said bracket 27 maintained always in the same relative position with re-4 um of the bracket 27 carries the field of themotoralso, so that there may be no relative l l motion between the armature and the field.

from the field-ring of the motor an In other words, the motor swings as an entirety withl the centrifugal about the member 5. As a further steadying means for thefield portion of the motor I employ the bracket 28, which is secured at its upper end to the field-ring 23 andcarries at its lower end the bearing 29, through which passes-the shaft 14. This bracket is not indispensable.

The brushes 30 of the motor are sup orted bear y'upon the commutator 31 in the well-known manner;

From the foregoing description it is ap arent that I.v have devised an electrical rive for centrifugals in which the greatest econv om in space or head room has been effected an in which the field and armature of the motor occupy at all times the same relative position with res ect to each other irrespective of the centri gal or its deflection.

A hand-lever 64 is mounted upon the curb 13 and is adapted to communicate with'the electric controller forthe motor.
