W'ILLIAIC MARK MUCHOVJ, 0F EVANSTON, ILLINGIS, ASSIGNOR- TO FLOSSY DENTAL MFG. GL1, OF EVANS-3330M, ILLINOIS, ii. CORPGRJLTIOFLI G1 ILLINGIS.
Application filed August 12, 1921.
To all whom it may concern:
Be it known that I, VVILLIAM MARK lt luorrow, a citizen of the United States, and resident of Evanston, in the county of (look and State of Illinois, have invented certain new and useful Improvements in a Dentists Drill Cleaner, of which the following is a specification.
My invention relates to dentists appliances and particularly to a novel motordriven cleaning device having a peculiar motion and effectively serving to perform the desired functions.
One of the objects of my invention is to provide a device of the character described which is adapted to effectively clean the drills of variousshapes commonly employed by dentists, the result being secured by bringing the drills into contact with the surface of a circular brush mounted for compound movement. The peculiar movement is secured by pivoting the brush in bearings, one of which is concentric and the other eccentric to the axis of rotation. This results in a wobblinp; motion, the periphery of the brush defining a olute curve. Thus the action of the brush on a stationary object, such as a drill, is in two directions. Provision is also made for manually moving the drill about the periphery of the brush in order that all sides of the drill may be brought into contact.
In addition I provide means associated with the brush for reducin the air pressure in the space beneath the brush, whereby the particles removed from the drill are received within a chamber having a reticulated wall covered by fabric through which the air is expelled. the particles being re tained by the fabric. Provision is made for removal and replacement of the fabric as required.
The invention will be more readily understood by reference to the accompanying" drawings. wherein,
Fig. 1 is a side elevation of a device con structed in accordance with my invention;
Fig. 2 is a plan view thereof;
Fig. 3 is a sectional view on the 33 of Fig. 2; I
Fig. 4 is a sectional view on the l4 of Fig. 3;
Fig. 5 is a 5-5 of Fi 3-;
sectional view on the. line DRILL CLEANER.
Serial No. 491,850.
i 6 is a fragmentary sectional view line (S -6 of Fig. 8; and
7 is a fragmentary sectional view on the line 77 of Fig. 2.
In the drawings it will be seen that 1 pro-- vide a frame 10, adapted to support a motor 11, the armature shaft 12 of which projects upwardly and terminates in a member 13, having an ofiset hearing or seat 14L. The member 13 is, in effect. a pitman as the bearing; lei is laterally offset from the center of rotation of the sh aft and serves as a support for a shaft 15. carrying at its upper end a brush 16 of circular form having radial bristles 17. in. order to prevent the entrance of dislodged particles into the bearing 14 I provide ahood or cover 14', the edges of which overhang: the hearing". as best shown in 3. The upper end of the shaft 15 is carried in a bearing" 18, constituted by the concaved lower end of a threaded member 19. The bearing 16 is concentric to the armature shaft and brush.
Fixed to the member 13 is part havino' a horizontal upper wall 20 and side walls 2], fan blades 22 being secured to the wall 20 for a purpose to he later described. Projectingr from the side walls 21 are the horizontal portions 23 of a cup-shaped devicehaving an open top. and reticulated side walls 24. These side walls may consist merely of a screen of small mesh of suilicient stiffness to be self-sustaining under the rotation imparted to the device. Mounted on the inner surface of the wall 24 is a fabric band 25 which may contain a sterilizin a substance.
The parts just described are incased within a cylindrical wall 26. fitted within a suitable recess in the top member of the frame 10. The casing 26 is provided with one or more openings 27 permitting the escape of air from the interior thereof. The top of the casing 26 is closed by a wall 28 having an upstanding annular flange 29, the inner surface 30 of which is curved. terminating at a point close to the periphery of, the bristles switch 33 is indicated but this will be positioned at a suitable point for the most convenient operation.
It will be noted that the driving force applied to the brush is frictional only, this having been found to be ample and to obviate certain difficulties.
The fan blades together with the action of the brush create a peculiar air condition whereby a suction is created past the periphery of the brush and an increased pressure at the periphery of the rotating reticulated wall. Thus any particles removed from the drill are drawn into the space beneath the brush and are projected against the fabric and held thereby. I will not herein attempt to explain the reason for this peculiar action.
In operation the brush being rotated, a drill is placed in the circular space 34, as shown in Figs. 2 and 3, and manually moved angularly around the slot as far as permitted. This resultsin presenting all of the surface of the drill to the action of the brush and the peculiar action of the bristles serves to remove particles both from the longitudinal and circular grooves in the drill. The wobbling action of the brush shaft serves to combine an up-and-down and a rotary motion, and all of the recesses in the drills are thoroughly cleaned. When it is desired to replace the fabric 25 the casing 26 and the parts supported thereby are lifted, thus readily giving access to the interior of the device.
Obviously the device is capable of much modification and I do not wish to be limited except as indicated in the appended claims.
I claim:
1. In a tool cleaning device, the combination of a driving shaft, a driven shaft, a brush supported by the driven shaft, one end of said driven shaft being concentric and the other end eccentric to the driven shaft, and means for supporting a tool in proximity to the periphery of said brush.
2. A cleaning device for dental tools com prising in combination, a driving shaft, a driven shaft forming in effect a continuation of the driving shaft, the connection between the driving and driven shafts being eccentric, the free end of the driven shaft being concentric, a brush supported by the driven shaft, and means for holding a tool in sur-,
face contact with said brush.
3. In a device of the class described, the combination of a shaft adapted to be rotated, a substantially parallel shaft forming a continuation of the first shaft, an eccentric connection between the two shafts, a brush carried by the second shaft the parts being so arranged that the brush is caused to wobble, and means'forming a guide for a dental tool around the periphery of the brush.
4. In a device of the class described, the combination of a circular brush, means for imparting a Wobbling, rotative movement to the brush, a fan'rotatablewith the brush, means I for guiding a tool adjacent to the periphery of the brush, and a fabric wall surrounding said fan, whereby particles dislodged by said brush are withdrawn by said fan and deposited on said fabric walls.
Signed at Chicago, Illinois, this 9th day of August, 1921.
WILLIAM MARK MUCHOW.
