CARVING 1 NSTRUMENT Filed Jan. 9, 1930 Patented Sept. 6, 1932 CHRIS S. VAN HORN, OF BLOOMSBURG, PENNSYLVANIA canvine INSTRUMENT Application filed January 9, 1930. Serial No. 419,674.
This invention relates'to improvements in carving instrument, and is more particularly directed toward an instrument for carving wax or similar solid or plastic material. A
As is well known in many arts,it is necessary to cut away the surface of a solid or plastic body to bring it to a' desired external shape. Thus, in the dental art, after a cavity has been out to the desired shape, it is filled withwax and a wax pattern thus prepared. It is necessary to carve this model in order to bring it to the desired form. The present invention is particularly adapted for employment in the dental art, in which small and delicatemodels are being prepared.
According to the present invention, a carving instrument is provided which may be employed either by pushing or pulling for obtaining the desired shaping of the wax model, since by its construction it easily and smoothly follows the tooth form in shaping, cusps, sulci and contours of occlusal,
buccal and lingual aspects. Particularly, the
particular angle or rake of the posterior or anterior cutting edge frees the instrument from liability of digging into the wax model, so that definite shavings may be removed at each cut, the thickness of the shaving being regulated by the angle of presentment to the work and the pressure, etc., as exerted by the operator. It is thus possible to prepare the most delicate and feather-edged margins with a clean and true carving and without danger of fracturing or chipping the wax.
One example of construction of such an instrument is shown by way of example on the accompanying drawing, in which:
Figure 1 is a view of such a carving instrument as a whole.
Fig. 2 is a side elevation of the same on an enlarged scale. 7
Fig. 3 is a corresponding face elevation on the same scale as Fig. 2.
Figs. 4 and 5 are successive sectional views of the same substantially on lines 4:"4: and 55 of Fig. 3.
Figs. 6 and 7 are elevational views in the direction of the arrows 6'and 7 in Fig. 2. 50 In the drawing, the handle 10 of the tool is provided at oneend with any desired shaping instrument 11 for interproximal prepa-- metrical and are designated at 15, 16 in Figs. i
4L and 5, joining one another at a ridge which extends from end 13 to end 14 and lying along an arc and being substantially in a plane.
The upper surfaces are preferably of differing dimensions, the anterior surface 1'? being wider than the posterior surface 18: these two surfaces, however, preferably blend into one another by a transverse curve. It will be noted from Fig. 2 that the goose-neck supports the head at a position in the rear of the line of direction 19 of the stem: and that the posterior upper surface 17 lies substantially in a plane forming an angle A with thisline of direction 19, of about while the angle B of the posterior upper surfaces, near the goose-neck, is slightly greater, being of the order of Also, it will be noted that the central element 20 of the posterior lower surface may be substantially at a right angle with respect to the line of direction 19, S5
while corresponding elements 21 of the posterior lower surface are almost parallel to the line of direction 19.
As will be noted from Fig.6, the head preferably is symmetrical with respect to the stem, and has the anterior cutting edge 22 and the posterior cutting edges 23, the latter being separated from the goose-neck 12 by slight indentations: as is to be seen from Fig. 7, the posterior surface .of the gooseneck blends smoothly into the posterior lower surface of the-head. In the successive sections of Figs. 1 and 5,'it will be noted that the head in these successive planes has a lozenge-shaped cross-section, the, elements of buccally (tongue to cheek) when removing rather broad shavings of wax and in, preparing the corresponding margins and the marginal ridges. V The posterior arcuate cutting edges formed by the junction of the, posterior surfaces 16 and 18 serve more especially, in conjunction with the points 13 and l4 and the immediate contiguous anterior cutting edge, in forming the pulpo-occlusal asp cct of the cusps and tracing out the sulci in both the rec inked mesio-distal and bucco- What lclaini as new and desire to secure by LettersPatent is: a j
l. A carving tool comprising a stem and a head extending transversely at the end of stein, said head having a continuous an i e for employment by pushing said stem and cutting edge adjacent said stem for employment by pulling said stem.
2. A carving tool comprising a stem and a Q he ed, said head extending symmetrically and tr nsversely at the end of the stem and havco? nuous anterior cutting edge extending from one of the head to the other for employment by pushing said stem, and a pair of posterior cutting edges extending from the stem to the respective end of the head for employment by pulling said stem. 3. A carving tool comprising a stem and a head, said stem joining the head by a gooseneck JO mat the head is posteriorly offset f direction of the stem, said from the line or head ei:teiirl'.-.i.g symmetrically on each side of said stem and havin continuous curved, anterior cutting edge substantially lying in a. plane and extending from one end of tl e head to the other, and a pair of posterior cutting edges extending from the goose-neck to the'respective end of the head.
4. Acarving tool comprising a stem and a head, said head having anterior and posterior upper and lower surfaces so'that it is of ap proximately lozenge-shape in cross-section, the anterior upper surface being located approximately at an angle of 35 to the line of direction of the stem, and the posterior upper surface being located substantially at an an- ;ual directions, and by reason of the angle oyed and the offset oosition of the head gle of 40 to the line of direction of said stem,
5. A carving tool as in claim 4, in which cutting edges, said head being of approximately lozengeshape cross-section in successive planes parallel to'the line of direction of the stem in which the ends of the major diagonal of the lozenge represent the cutting edges.
8. Acut-ting tool as in'claim;7,' in which the upper anterior surface is broader than the upper posterior surface. y
9. A cutting tool as in claim 7, n which the two lower surfaces are substantially symi'netrical and joined at an arcuat-eridge'located substantially in a plane.
10. A carvingtoolcomprisinga stem and A a head, said head having curved anterior and posterior bottom surfaces which meet in a ridge extending from end to end of the head, sa" d surf-aces beingsubstantially symmetrical with respect to said'ridge and with respect a ton plan-e am right angle thereto and including the line of direction of said stem, the
anterior bottom surface being at the intersection of said latter plane" of symmetry substantialiy at a right angle to the line of the stemand curving slightly in the direction of the stem toward-its ends, anterior and posterior top surfaces defining respectively an anterior cutting edge with said anterior bottom surface and posterior cutting edges with said posteriorbot-tomsurface, said anterior top surface being substantially a plane.
11, A carving tool as in claim 10, in which the plane of the anterior top surface is located at an angle of approximately 35 to the iine of direction of the stem.
12' A carving tool as in claim 10, in which the stemcomprises an offsetgoose-neck portion'joiningiit with said head, and the exterior surface of the goose neck merges into the posterior lower surfaceof the head, and the posterior cutting edges are cut away adjacent the goose-neck.
In testimony whereof, I aflix my signature.
