Specification of Letters Patent.
Patented Jan. 1, 1918.
Appli-cation led December 18, 1916. Serial No. 137,584.
T0 all whom 'it may concern Be it known that I, SHniziDaN RisLnY, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State ol Ohio, have invented certain new and useful Improvements in Dental Tools, of which the following is a specification.
This invention relates to dental tools and more particularly to whatI are known as condensing tools used for condensing or compacting fillings. The object of the inveiition is te improve such tools by the provision of a working face so constructed as to take a good hold of the material being worked and compact it without slipping or yielding thereon and which tool is nevertheless capable of being readily cleaned or Jfreed from adhering particles of the filling material.
The invention comprises the condensing tool hereinafter described and claimed.
In the drawings, Figure l illustrates one form of tool embodying the invention; Fig. 2 is an enlarged view of the tool head; Fig. 3 is an end view thereof; Fig. 4iis a cross section on the line 4-l, Fig. 8; Figs. 6 and 7 are views corresponding to Fig. 3 and showing other forms of tool embodying the invention; and Fig. 8 is an elevation of still another form of tool.
The tool shown in the drawing comprises a main body or shank l preferably rougheiied or knurled to give a better finger hold and of any suitable cross sectional shape. Said shank may be the usual long straight shank for purely manual use, Fig. l, or may be provided at its upper end with a. lateral extension 2 having a rounded head 3 for engagement by a mallet or other blow producing instrument, as shown in Fig. 8. v
The other or operating end of the tool has a portion 4 which is curved in any suitable manner to locate the working head 5 in the proper' place and at the proper' angle to most conveniently reach the desired tooth or portion of' the cavity therein, as will be readily understood. The working head of the tool has an end face 6 which is brought into contact with the filling to condense or compact the same. Said face may be a flat CDpes ef this patent in ay be obtained for Yrive cents each, by addressing the as shown in' face in a single plane or may be concave or convex, as desired, and is shown as convex. It is provided with a shallow narrow groove or channel 7 extending around its periphery near its outer edge. The groove may be formed in several ways. For example if' the tool face is round or elliptical, as in Figs. 3 and 5 the groove will be a single continuous groove following closely the line of the edge of the working face. If, however, the tool face is substantially square or rectangular or of any other polygonal form the groove will be formed of a series of channels each parallel to a side edge of the working face, as in Figs. 6 and 7. Either arrangement leaves the central main portion of the working face smooth and uninterrupted.
The construction described is easy to clean because any particles of material which may lodge in the groove can be readily wiped or scraped out by motion of the cleaning cloth or device along the groove. In this respect it is to be clearly distinguished from prior tools having a working surface roughened all over by two series of crossed grooves which quickly become choked and are quite difficult to clean. At the same time my improved tool has a better hold on the filling material during the condensing operation than a. tool having a continuous smooth face free of grooves. Such tools slip on the material and appear to allow it to escape beyond the edges of the working "face, whereas the present tool grips the material and carries it down into the body of the filling and condenses the same. Further adthereby those skilled in vantages will be apparent to the art.
lVhat I claim is l. A condensing tool having a working face provided with a groove parallel with its side edge and extending entirely around the same, the central portion of said face being smooth and uninterrupted. Y
2. A condensing tool having a working face provided with a groove parallel with its side edge, the central portion of said face being smooth and uninterrupted.
In testimony whereof I ailix my signature.
