Definitions
- This invention relates to mixing tools generally and pertains more particularly to a tool adapted as a dental accessory for mixing dental paste, such as the paste used in the filling of teeth, for making denture casts and the like.
- One object of this invention is to provide a mixing tool or" the character described which can be readily applied to a dental hand drill such as is ordinarily used by dentists.
- a further object of this invention is to provide an improved mixing device constructed in accordance with the preceding paragraph wherein the body is also provided with a relatively large central opening which permits some of the paste being mixed to pass therethrough so that when the mixer is driven at a high rate of speed, it will not create a void in the paste or ial being mixed but will substantially continuously permit some of the material to be presented for mixing by the paddle or body.
- the body 1 is provided with a pair of diametrically opposed tip portions 4 and 5 which are curved at 6 outwardly in opposite directions from the remaining major portion of the body it located therebetween. These tip portions are in the shape of sectors of the circular body 1 and constitute only a minor portion of the entire body.

Appiication November 14, 1955, Serial No. 546,597
1 Claim. (Cl. 32-4ti) This invention relates to mixing tools generally and pertains more particularly to a tool adapted as a dental accessory for mixing dental paste, such as the paste used in the filling of teeth, for making denture casts and the like.
One object of this invention is to provide a mixing tool or" the character described which can be readily applied to a dental hand drill such as is ordinarily used by dentists.
Another object of this invention is to provide an improved mixing tool including a substantially fiat circular body portion or paddle having an elongate stem rigid therewith and projecting radially therefrom for connection with an associated hand drill, the paddle including diametrically opposed sectors curved outwardly of and in opposite directions from the main body portion thereof for adapting the mixing paddle for high speed operation.
A further object of this invention is to provide an improved mixing device constructed in accordance with the preceding paragraph wherein the body is also provided with a relatively large central opening which permits some of the paste being mixed to pass therethrough so that when the mixer is driven at a high rate of speed, it will not create a void in the paste or ial being mixed but will substantially continuously permit some of the material to be presented for mixing by the paddle or body.
A still further object of the invention is to provide a mixing tool for use with dental engines and having simplicity of desi n, economy of construction and eificiency in operation.
The novel features that are considered characteristic of the invention are set forth with particularity in the appended claim. The invention itself, however, both as to its organization and its method of operation, together with additional objects and advantages thereof, will best be understood from the following description or" a specific embodiment when read in connection with the accompanying drawing, wherein like reference characters indicate like parts through the several figures and in which:
Figure 1 is an elevational view with parts broken away showing the improved mixing tool connected with a conventional dentists hand drill and showing the same in operation;
Figure 2 is a sectional view taken substantially along the plane of section line 22 of Fig. 1;
Figure 3 is a perspective view of the improved mixing tool, and
Figure 4 is an end view taken substantially along the plane of section line 44 of Fig. 3.
Referring now more particularly to the drawing, specifically to Figs. 3 and 4, the improved mixing tool will be seen to consist essentially of a circular and generally fiat disc-like body or paddle 1, having formed integrally therewith or rigidly attached thereto a stem member 2, the stem ice projecting radially from the body and in a common plane therewith. The stem 2 is connected to the body 1 at a peripheral point 3 thereon as is clearly shown in Fig. 3.
The body 1 is provided with a pair of diametrically opposed tip portions 4 and 5 which are curved at 6 outwardly in opposite directions from the remaining major portion of the body it located therebetween. These tip portions are in the shape of sectors of the circular body 1 and constitute only a minor portion of the entire body. Thus, the body is substantially S-shaped in cross section as will be most clearly evident from Figs. 2 and 4.
In addition to the two above-mentioned tip portions 4 and 5, the body may be, and preferably is, provided with a relatively large central opening 8 which is concentric therewith and which materially aids adapting the paddle or mixing device for high speed operation.
When in use, the above-described device is intended for utilization in conjunction with a conventional dentists hand drill it) having the usual chuck 9 thereon. The free end of the stem 2 is securely held within the chuck 9 so that the paddle i may be rotated at high speeds.
Thus, for all practical purposes, the paddle 1 may be maintained in a stationary position Within the mixing bowl 12., whereas at the same time the mixing action thereof will be substantially continuous. Of course, during actual operation, the paddle will be moved about in the bowl to more rapidly effect the thorough mixing of the entire contents thereof. It has been found that by utilizing the above mentioned tool, mixing of paste-like material is effected much more efficiently and rapidly than by the conventional practice of mixing the paste by a. hand manipulated spoon, pestle or the like.
Although a certain specific embodiment of the invention has been shown and described, it is obvious that many modifications thereof are possible. The invention, therefore, is not to be restricted except insofar as is necessitated by the prior art and by the spirit of the appended claim.
What I claim is:
A mixing tool comprising a substantially flat, circular paddle, an elongate cylindrical stem rigid with and extending radially from the periphery of said paddle, said paddle having a pair of diametrically opposed, oppositely directed tip portions curved outwardly of the remaining major portion of the paddle, and said paddle having a concentric central opening to permit material being mixed to pass therethrough for substantially continuous presentation to the paddle.
