. This invention relates to amalgamators for use in the dental profession,-and aims :toima prove generally the construction oftheamal ,A further object of the invention istto' structed thatthe material held in the measuring portion of the device may be dropped into the rubber container forming'a part of the invention, by the operation of a slide 2 'valve. f y

With the foregoing and other objects in i view which willappear as the description proceedsftheinvention resides in the combination and arrangement of parts and in p 1 It Wlll be seen that due toth1s construc-- tion, the valve 12 also provides a bottom for;

the details of constructionhereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein within the scope of what is claimed, without 30 Referring to the drawing:

Referring to. device includes a hollow body portion 5 formed with internal threads at the lower end thereof, whichthreads cooperate with threads ofthe removable bottom 65, forming a part of the body portion. 7

A circular flange 7 extends inwardly from the inner surface of the hollow body por tion and is disposed adjacent to the upper.

end of the body portion as clearly shown by a support for the rubber container indicated at 8, and which is suspended within the body portion, by the flange'9 restingon the flange 7, the flange 9 being formed integral at the 65 upp er end of the rubber container 8. The body portion is formed with an upprovide a device of this character so condisclosed, maybe made departing from the spirit of the-invention;

The amalgamator shaft is indicated by the reference character 14' and extends through the'housing 15, the inner end -there-' of'resting in an opening as at 16; The inner end of this shaft 14 is formed, with an ofiset 7 portion 17 on which the roller 18 is mounted, the offset portionj'of the shaft being such" as to cause the roller 18 to contact withthe lower tapered end of the container 8 throwaccomplishing the amalgamation thereof.

7 thereby eliminating the necessity of employing a separate form of engine for rotating the shaft.

We claim:

1. An amalgamator including a body portion, a container supported in the body portion, a removable measuring member supported on the upper end of the body portion, a valve disposed between the upper end of the container and measuring memberfor controlhng the passage of material to the container, and means for agitating the container to amalgamate the material contained therein.

I 2. An amalgamator including a body por tion, a. container in the body portion, a cloat the upper end of the body portion and having a funnel-shaped opening, a valve member above the container, said valve member adapted to uncover the bottom of the measuring member to allow material to pass into the container, and said valve member adapted to be clamped into engagement with the container by the measuring member to close the container.

4. An amalgamator including a body portion, a container supported in the body portion, means operating in the body portion for agitating the container, a valve for normally closing the upper end of the container, a measuring member above the valve and container, said valve providing a bottom for the measuring member, said measuring member adapted to normally hold the valve in its active position, and said valve adapted to move to allow material to pass from the measuring member into the container.

5. An amalgamator including a body portion, a container in the body portion, a measuring member for directing material to the container, a slide valve for normally closing the container and held in itsclosing position by the measuring member, and said valve adapted to move to its open position to allow material to pass from the measuring member into the container.

In testimony that we claim the foregoing as our own, wehave hereto affixed our signatures.
