Definitions

  • the construction of the angle plate and handle for dentists boring machines is improved according to this invention, in such a manner that the inner parts can be taken out after the handle has been screwed out of the angle plate and of the casing so that these inner parts can be rapidly cleaned after the instrument has been used.
  • the casing is closed at the front part by a removable angle plate, one arm of which is securely fixed to the casing by means of the handle, the other arm of said angle plate carrying a sleeve designed to serve as hearing for the pinion which rotates the drill.
  • Fig. 1 in side elevation, and in Fig. 2 in longitudinal section.
  • Fig. 3 1s a similar view as Fig. 2, the handle and angle plate being removed.
  • One arm of the angle plate I is maintained in the working position through the handle 0 which engages with an opening d of the said arm'of the angle plate I), this arm being thus fixed to the casing.
  • the other arm of the angle plate 6 has a sleeve 6 which serves as journal bearing for the driving wheel 9 of the drill 7".
  • the handle a is screwed out of the casing a and the angle plate removed (Fig. 3) whereupon the inner parts can be taken out easily to be cleaned or repaired.
  • the slide plate h of the casing a, has at its front end an indentation i which engages with notches in the shaft of the drill f.
  • said slide plate which is parallel with the handle 0 has a slot 70 through which an abutment screw Z is screwed.
  • the slide plate It is bent oil at an angle at its rear end, this part at serving as handle for the slide.
  • An improved angle plate and handle for dentists boring machines comprising in combination with the casing, the drill and a pinion for rotating the drill, an angle plate removably mounted upon the casing and having an opening in its lower arm, a sleeve at the upper end of said plate serving as journal bearing for said pinion, and a handle inserted through the opening in the lower arm of said angle plate and screwed guided in the side walls as a journal hearing for the pinion of the drill shaft, and an extension at an angle to the arm having an opening adapted to receive the handle of the dentists boring machine.
