llVlPROVEMENT IN ELECTRIC DENTAL PLUGGERS.
Specification forming part of Letters Patent No. 216,055, dated June 3, 1879; application [iled December 20, 1878.
To all whom it may concern.-
Be it known that I, EDWIN L. PAINE, of the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Electric Pluggers for Dental. or Analogous Uses; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to letters of reference marked. thereon, which form a part of this specification.
This invention relates to improvements in electromagnetic dental tools.
My invention relates, specially, to dental pluggers, but is also adapted to various purposes ineidental to operative dentistry; and consists, principally, in improvements in the motor actuating the tool.
The accompanying drawing, making part of this specification, is a sectional view of the several parts in combination.
A and A are bobbins, secured in the framebar B. to the head of bobbin A, and terminates in a hinge-joint, G, the axis of which is in the plane of the heads of the bobbins A A.
The armature D is hinged in the joint 0. The axis of the bobbin A is drilled out, and a spiral spring, E, is inserted, one end of which rests against the armature D, and the other on the end of an adj Listing-screw, F.
The bobbin A is likewise drilled through its axis, through which the tool-barH reciprocates up and down and the stock I is screwed onto the shank of bobbin A. A spiral spring, a, is so secured to the bar H as to insure proper contact of the bar H and armature D.
The bar is prolonged and turned up L is an adjusting-screw, supported by the arm M, which is in its turn secured to the frame-bar B by the binding-post 0. One end of the wire on the bobbin A is fastened to the frame-bar B, and the other to the insulated binding-post c.
The circuit of the coils on the bobbin is broken at c, and restored when the spring tinger-piece d is brought in contact with c.
This arrangement only relates to making the circuit or opening and closing the same, and possesses no novelty thatI claim; but the vibration of the armature l) is accomplished by contact of the adjusting-screw L with the release'spring it. Contact might be direct between the screw L and armature D without the intervention of the spring h but in that case the range of vibration of the armature is extremely limited and the instrument subject to injurious work.
I disclaim electric alarms of any kind; but
That I claim is- The construction of an electric dental plug ger having the release-spring h secured to the top of the armature D, operating upon the hinged joint (J, in combination with adjustingscrew F, to raise or lower the spring E in the axes of an independent bobbin, A, substantially as above set forth.
In testimony that I claim the foregoing as my own I aliix my signature in presence of two witnesses.
EDWIL L. PAINE.
