This invention relates to dental devices and particularly to a device for mixing investment material.
The invention contemplates a novel form I of paddle operating within a container in.
such a manner that the investment material is uniform in texture, there being no lumps or air bubbles after treatment thereof.
An object of the invention is to provide a device for the treatment of investment material or any similar material so arranged and constructed that the investment material may be easily removed from the device, and regardless of a hardening of the investmentmaterial within said device.
Other objects include a device which is simple of construction, positive in operation and generally superior in use and service- Figure 1 is an elevation partly in section of the improved dental device;
Fig. 2 is a plan view of the device;
Fig. 3 is a perspective view of a paddle used in practicing the invention, and
Fig. 4 is a cross sectional view on line 44 of, Fig. 1.
Corresponding parts in all the figures are designated by the same reference characters.
Referring with particularity to the drawing, the improved dental device is designated as an entirety by A, of which a is a paddle, b a container adapted to receive said paddle, a a casing for the container 6 and d means for rotating container 0, all of which elements may be utilized in practicing an embodiment of theinvention.
The device includes a base 1 adapted to support a standard or pedestal 2, the pedestal being provided with an arm 3 which is bifurcated at one end as 4 to receive a head 6 of a stem 7. The head 6 and stem? form a particupart of the-paddle a. This head is formed with a peripheral groove 8 within which groove is received the bifurcated end 4, and the head is enlarged at 9 torest on the top surfaceof said arm 3. A lock nut 10 is threaded to thearm 3 for engagement with the head to. hold the same in-a selected posiftionrelative to the-arm, The paddle includes, the member 11, which. is'carried -by the stem 7 and which member is provided with a curved 50 *tongue 12,'eXtending:from'Ta side 13of said member andtspaced from top and bottom ends 14: and '15 of saidamember. Said memberwll ois "likewise slotted at-16 to provide two extensions the ends of which are curved. asshownat '17 and18- and the bottom end is likewise scream-19.: g .The .container. his preferably formed of someflexible. material and iscup shaped, beingprovided. ingthe present instance with a. tapered walland witha-rim flange 20. The
casing c includesra base 21 formed'with an annularrim flange 22,;and with an annular portion.. 23= adapted to surround the conr ta'inerfb. A cap member 24:1is adapted'to secu're the rim flange'20. of said container to-the annu-lus 23 asshown in Fig. 1. This cap is likewise provided with a central. bore .25 .to'v permit passage of the stern? therethrough. The casing 21 is rotatably mount-- ed in I a standard 26', which standard is secured to the base 1. This standard is formed with a central bore, 27 within which is received a stud shaft 28, which stud shaft is secured to the base 21 by a suitable means 29. p
The motor at is conventional in form and the shaft thereof carries a friction member 30 which bears against the inner surface of the rim flange 22 of the base This motor is likewise anchored at 31 to thestandard 26.1.90
A switch 32 controls operation of the motor, a cord 33 leads from said switch to a suitable source of current supply. The operation of the device just described is as follows:
Investment material is usually mixed with water and this investment material is placed within the cup or container b. It is necessary that this investment material should be of fine texture or smooth'and free from all lumps, otherwise a casting made from the investment material would be defective. The switch is turned so thata source of cur- 1 rent is directed to the motor d and the motor shaft upon rotating will rotate the casing a, which in turn will rotate the container or cup Z2 inthe direction of the arrow shown in t Fig. 4. The member 11 of the paddle is held stationary and as the container rotates relative thereto the investment material is 1 smoothed by action of the curved edges of said member'l-l and directed through the slots 16 and 19 and likewise between the edge J 13 and the curved part 12. As the cup or container 6 is flexible in nature it will give 15 slightly during this smoothing operation of the investmenti'naterial. If for any reason theinvestment material should be left Within thecontainer or cup and become hard, such investment material may be readily broken 10 from the cup or container due to its flexible qnature fillClgWlthOllt thenecessityof trying to chisel the investment material therefrom,
i which,of'course, would be'necessary if the 1 container was not-sfiexible,
i It is obviousthat'variouschanges, modifications and variations may be made in practicing theinventioniin departure from the particular showing of the drawingwithout departing from thejtrue spirit of the inven- Having thus disclosed In invention, I claim and desire toise'cure by et'ters Patent:
In a dental device adapted to mixinvest- 'ment material, a'casing, a flexible container .1 35 within said casing and in part spaced therefrom, a stationary paddle adapted to contact substantially withthe entire inner surface of j the flexible container and provided --with slotted tportions. adapted to permit passage .therethrough of investment material within the container when the container is rotated, and means'for rotating the said casing and p container. r i
, In testimony whereof, I have signed my 45 'nameto'this specification.
