UNITED STATES PATENT OFFICE.
LOUIS MAILLARD, OF GALT, CANADA.
DENTAL DRILL.
SPECIFICATION forming part of Letters Patent No. 482,558, dated September 13, 1892.
Application filed March 31, 1892. Serial No. 427,230. (No model.)
To all whom it may concern:
Be it known that I, LOUIS MAILLARD, of the town of Galt, in the county of Waterloo, in the Province of Ontario, Canada, have invented a certain new and useful Improvement in Dentists Burring-Tools, of which the following is a specification.
The object of my invention is to form the cutting-edges of the burring-tool in such a manner that they will each present a clean shaving or cutting edge and have ample clearance, so that the tooth substance will get away freely without interfering with the cutting-edges; and it consists, essentially, in the peculiarconstruction, arrangement, and combinations of parts, hereinafter more particularly described, and then definitely claimed.
In the accompanying drawings, Figure 1 is an enlarged perspective view of my improved dentists burring-tool. Fig. 2 is an enlarged plan of same.
As a rule dentists excavating or cavity burrs are made of different shapes and sizes and shaped to out into the tooth substance Whether by directing the pressure on a line with the axis of rotation or at any angle to this axis; but in the formation of burrs other than mine their cutting-edges are apt to clog and make the operation painful to the patient. By the adoption of my device work may be done more rapidly and will cause much less pain than any other burr with which I am familiar.
On reference to the drawings it will be seen that there are four spiral cutting-edges A. These edges are somewhat of a spiral form, and the clearing-spaces are made so as to give the cutting-edges sort of a hook-shape, enabling them to out freely, like the cuttingedges of a twist-drill. It will be observed that two of the cutting-edges A connect in the center, While the others are cut away and pointed at their lower ends, leaving clearingspaces B, which allow the chips to fall out freely without any danger of them clogging the cutting-edges of the instrument. Between the pointed cutting-edges and the connected ones are other cutting edges 0, running from the points of the pointed cutting-edges to those that are connected. I do not confine myself to any particular number of cuttingedges; but I think that the form shown in the drawings, in which only four cutting-ed ges are employed, will be found preferable.
What I claim as my invention is A burr-drill having a series of hook-shaped cutting-edges, two of which are joinedin the center and another two terminating in points on opposite sides of the first two, and cuttingedges running between the pointed and continued cutting-edges, substantially as described.
Galt, February 13, 1892.
LOUIS MAILLARD. In presence of W. W. LAIDLAW, WM. WALLACE, W. S. TURNBULL.
