DENTAL DRILL. APPLICATION FILED FEB- 20. I9I9- Pateted Nov. 11, 1919.
1111111 IITINII @tto-L ms wirf/meco FRANK F. SCHLUETER, 0F WATERTOWN, YWISCONSIN'.
To all whom t may concern.' 1 n y Be it known that I, FRANK F. SCHLUETER, a citizen of the United States, residing at Watertown, county of Jefferson, and State of Wisconsin, have invented new and useful Improvements in Dental Drills, of which the following is a specification.
My invention relates to improvements in paralleling attachments for dental drills, thisapplication being a companion application, copending with one iiled by me December 24th, 1918, Serial No. 266904, under a like title.
The object of the present invention is to provide means, whereby the gage post or pin may be brought into close proximity with a drill Y or other tool,-to provide means, whereby a drill or grinding wheel may be moved fromv one position toanother while the paralleling post remains iixed, or` an-V chored, in a` previously formed socket within which it merely oscillates about its own axis during the movements of the drill or other tool from one point of operation to another,-to further provide means whereby a tool employed for cutting away the surface of a tooth may be moved in a circle, or 'along a curved line, and its movements so controlled as to cut a cylindrical or other curved surface, all vertical lines of which are par` allel with the axisof the gage pin when anchored in a previously formed socket Y more or less distant from the field of cutting operations,-and to provide more convenient means than thatdescribed Vin said former application for varying the distance between the gage pin and the cutting tool to suit the requirements of the work.
In the drawings c Figure 1 is a side elevation of a dental drill and its holder, with my attachment applied thereto, the holder and drill actuating connections being of that Vtype in which the body of the holder is at right angles to the axis of the drill.
Fig. 2 is a plan view of the same, with dotted lines indicating different positions Vof tool adjustment possible with anchored in a single socket.
Fig. 3V is a cross section, enlarged, on line 3-3 of Fig. 1.
L ike parts are identified bythe same reference characters throughout the several views-` c TheV drill holder A is of a common type of construction, in which the drill B is Sup-v Specfcation of Letters Patent.

ported at right angles to the body of the holden-the driving connections being such as to actuate the drill in this position. Such drills being in'common use, further description thereof is deemed unnecessary, except that l prefer to provide the drill holder with a nose piece or chuck l, having' a neck 2 of reduced size, and adapted to receive a forked clamping member having resilient arms 3 and 1, grooved on their inner faces to receive the neck 2. The extremities of the arms have beveled inner faces, as indicated at 6, whereby they may be pushed into position o f engagement with the neck 2, the arms socketed head l1, in which a slide l2 seats.,
The head 11 is open at the bottom, and the slide 12 may be pushed upwardly into this socket, `against the pressure of a coiled spring 13 seated in the upper end of the socket. A spring actuated latch 11iis securedto the outer surface of the head, and provided with an elbowed portion l5, which passes through an aperture near the lower end of the head, and engages a reduced' portion of the slide. This reduced portion of the slide may be away a portion of the slide which may be circular or cylindrical in form. The elbowed extremity 15 of the spring 11i serves to limit the vertical movements of the slide. 1 At the lower end of the slide, I provide a laterally projecting arm 20, which is' elbowed to provide a vertical post 2l, adapted to enter the socket formed in a tooth or in the root of a tooth, and to serve as an anchor post, and also'as a paralleling gage post to control the position of the drill B, whereby the latter will drill a vertical hole parallel with the socket in which post 21 is anchored, and whereby a cutting tool substituted for the drill B may 'be employed to cut surfaces having vertical lines parallel with the post 21.
The pivot post at 9 isalso parallel with thegage post 21, and occupies a vertical position in normal operations. This post permits the clamping fork 3 4 to swing in coperation with the arm 10, so as to increase or diminish the distance between the formed by merely cuttingdrill and the post 2l., and to allow the drill to be moved bodily in any direction within a plane at right angles to post 2l. That is to say, the drill may be moved freely in any direction, which does not require it to be tilted out of a position parallel with the post 2l.
rl`he arm 20 allows the post 2l to be offset sufliciently from the slide 12 and if desired this post may be brought into close proximity to the drill by turning the slide l2, so that arm 2O projects toward the drill, and by folding the clamping member 3-4E, and the arm l0, one upon the other, to one of thel positions indicated by dotted lines in Fig. 2.
ln this manner, it is possible to anchor the post 2l in a socket as close to the drill B as may be required for any dental operation, it being obvious that the post may be anchored in a tooth cavity, and the cutting tool operated to cut away the outer surface of the same tooth. Slides l2 may be provided, having arms 20 of varying length, whereby theextent to which the post 2l is offset may be varied, as required.
