SGHRY AND OTTO OESTEBIREICHER, F VIENNA, AUSTRIA-HUNGARY..
RTARY BRUSH.
Specication of Letters Patent.
Patented Jan. 14,1913.
Application led March 27, 1911. Serial No. 617,175.
Yin all whom it may concern.' y Be it lmown that we, FRANZ Sonnnr, engmeer, and O'r'ro Ons'rnRnEIcI-IER, gentleman, subjects of the Emperor of Austria-- Hungary, residing at Vienna, in the Empire of Austria-Hungary, have invented a new and useful Rotary Brush, of which the following is a specification.
Thisinvention relates to apparatus for cleaning'teeth and especially to that type of apparatus in which rotating brushes are used and the object of the invention is to arrange the apparatus in such a. manner that the rotating brush is connected Awith the mechanism for actuating'same and both parts are mounted in a casing which serves as a handle or the apparatus.
A hollow arm extending from and torming continuation of the casing may be 2turned and adjusted thereon as desired.
rlhe uppei' free end of this 'arm is curved and in its interior there is a flexible cable, carrying a 'chuck for the brush to be fixed thereto. ln case the adjusting device is dis- E engaged the bent arm may be adjusted eitherhby hand or automatically by means of the action of the conical gears and crank. We will now describe the invention with reference to the annexed 'Sheet of drawing in whicl1 Figure l is a front View, partly in section and Fig. 2 a sectional side view of the device, at 'right angles to Fig. l. Fig. 3 is'a section along the line 3-*3 of Fig.-1; Fig. 4l
is a detailed plan View of tha'loicking mechanism.
a is a casing serving as a handle for the apparatus. This casing has an extension A with inner threads into which is threaded an inner cylindrical piece sleeve A1 to fit thereon. o is a conical toothed wheel located in the hollow casing in suitable bearings, and provided with a crank hat the outside end of the axle of wheel c. A second conical wheel (i on 'a spindle c is in gear with wheel c. To the spindle e is fastened Vflexible.cable or tubo f which sible driving shaft and carries n its other end for the insertion nded a hollow arm z rota- .i in the casing a for the purloing the cable j and preventing 'ne' from damage or injury. This arm carries disk l having notches J70 onits periphery and is adjustably located in the casing a. A. latch lever m ulcrumed on the casing a may be brought into engagement with the notchesof the disk Z for fixing the latter in the desired position.,
The latch-lever m is rotatably mounted on the pivot2 which pivot is carried in the ring y which 1s clamped about the upper end of the handle a beneath the disk Z in such manner that the shoulder s yis adapted to be brought into engagement with the slots la in the disk Z and hold it against. rotation when `the free end of the latch m, is rotated out from the handle a.
The apparatus works as follows: When the crank is turned, rotary movement is Vtransmitted to the brush L by means of the gears c, d, spindle 'e and flexible cable f, so that the brush may be moved along the teeth with suliicient rapidity. By a suitable adjustment or displacement of the arm 'L' with regard to the casing a either by hand or after rotating the-latch out of engagement with disk l, or by the friction existing bctween spindle c and arm z', the latter is caused to make a slight turn, and the brush may be carried also along the hack side of the teetlnwithout in any way altering the position of the casing a and thereby the i teeth as well as the intersticcs between same may be thoroughly cleaned.
It is evident that the construction of the apparatus can be modified without departing from the scope of this invention, for example the conical gears may be omitted and the crank hc fitted directly upon au extension of spindle e outside the casing o but in this case the advantages ot' any easy handling and reliable function of the apparatus would he lost or at leastdiminished.
The apparatus as described and shown is simple in its construction, and allows cleaning of teeth' and ot the intel-slices between same in a reliable and efficient manner.
The adjustment of the hollow arm is necessary to allow cleaning of all surfaces of the teeth and tho interstices without materially moving the handle, which, as stated, contains the driving mechanism. lt' the hollow arm be not adjustable it would bc necessary for example to rotate the whole device for a halt revolutionl to cause the brush to vpress against the inner side of the tccth. T o actuate the device in a comfortable-and suitable way, it is' necessary to have the crank directednoutwardtor the reason that thc crank driving hand is free to-act. The ad-
