Abstract
Abstract A capsule holder is disclosed which is particularly adaptable for holding capsules utilized in dentistry where capsules are subject to rapid movement, such as rotational or reciprocating movement, required to triturate alloys or produce amalgamations. Two housings, one having a cavity adaptable for engaging one end of a capsule and also adaptable for rotating upward so that a capsule may be manually inserted into the cavity are attached to a base. The other housing which slidingly engages the base is movable so that the capsule is held between the housings. A latch is utilized to secure the housings against the capsule during the rapid movement or mixing operation.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
70 words
A capsule holder comprising: a base; a first housing defining a cavity for removably receiving one end of said capsule pivotally mounted to said base; a second housing slidingly engaging said base for moving along said base toward said other housing such that said second housing may engage the other end of said capsule; and latching means for compressively holding said housings against a closed capsule disposed between said housings.
Claim 2
Dependent Claim
70 words
A capsule holder comprising: a base; a first housing defining a cavity for removably receiving one end of said capsule pivotally mounted to said base; a second housing slidingly engaging said base for moving along said base toward said other housing such that said second housing may engage the other end of said capsule; and latching means for compressively holding said housings against a closed capsule disposed between said housings.
Claim 3
Dependent Claim
68 words
The capsule holder defined in claim 1 wherein said cavity of said first housing defines a cylindrical cavity and said pivotal mounting is such that said cylindrical cavity may be pivotal from a position approximately parallel to said base to a position where the axis of said cavity forms at least an acute angle with said base to facilitate the manual placement of a capsule in said cavity.
Claim 4
Dependent Claim
13 words
The capsule holder defined in claim 2 wherein said base comprises a plate.
Claim 5
Dependent Claim
22 words
The capsule holder defined in claim 3 wherein said cylindrical cavity contains a resilient pad for engaging one end of a capsule.
Claim 6
Dependent Claim
24 words
The capsule holder defined in claim 4 wherein said second housing contains a resilient pad, adaptable for engaging the other end of a capsule.
Claim 7
Dependent Claim
137 words
In a machine for producing dental amalgam and the like having a first surface adaptable for rotation about a first axis and a second surface nonaxially mounted on said first surface for rotating about a second axis, said second axis being parallel to said first axis and where said second surface is rotated in a direction opposite to said first surface; a capsule holder mounted to said second surface comprising: a first and second housing, for cooperatively engaging a capsule mounted on said second surface, at least one of said housings slidingly engaging said surface for moving along said surface toward said other housing such that a capsule disposed between said housings may be brought in contact with and held between said housings; and latching means for securing said housings against a capsule disposed between said housings.
Claim 8
Dependent Claim
137 words
In a machine for producing dental amalgam and the like having a first surface adaptable for rotation about a first axis and a second surface nonaxially mounted on said first surface for rotating about a second axis, said second axis being parallel to said first axis and where said second surface is rotated in a direction opposite to said first surface; a capsule holder mounted to said second surface comprising: a first and second housing, for cooperatively engaging a capsule mounted on said second surface, at least one of said housings slidingly engaging said surface for moving along said surface toward said other housing such that a capsule disposed between said housings may be brought in contact with and held between said housings; and latching means for securing said housings against a capsule disposed between said housings.
Claim 9
Dependent Claim
151 words
A capsule holder comprising: a base; a pair of sideplates vertically mounted to the upper surface of said base and spaced apart from one another; a first housing defining a cylindrically shaped cavity for removably receiving one end of a capsule and pivotally disposed between said spaced-apart sideplates, such that said housing pivots from a position where said cylindrically shaped cavity is parallel to said base to a position where tHe axis of said cylindrically shaped cavity forms at least an acute angle with the surface of said base; a second housing having a surface for receiving the other end of the capsule and slidingly mounted to said base for moving toward said first housing such that a capsule disposed between said housings and engaging said cavity and said surface is held between said housings; and latching means for compressively holding said housings against a closed capsule disposed between said housings.
Claim 10
Dependent Claim
151 words
A capsule holder comprising: a base; a pair of sideplates vertically mounted to the upper surface of said base and spaced apart from one another; a first housing defining a cylindrically shaped cavity for removably receiving one end of a capsule and pivotally disposed between said spaced-apart sideplates, such that said housing pivots from a position where said cylindrically shaped cavity is parallel to said base to a position where tHe axis of said cylindrically shaped cavity forms at least an acute angle with the surface of said base; a second housing having a surface for receiving the other end of the capsule and slidingly mounted to said base for moving toward said first housing such that a capsule disposed between said housings and engaging said cavity and said surface is held between said housings; and latching means for compressively holding said housings against a closed capsule disposed between said housings.
Claim 11
Dependent Claim
36 words
The capsule holder defined in claim 7 wherein said latching means comprises a generally U-shaped bar coupled at its ends to said second housing for cooperatively engaging and securing said first housing to said second housing.
Claim 12
Dependent Claim
37 words
The capsule holder defined in claim 8 wherein a bar is disposed between said sideplates and is coupled to a pair of ears on said first housing, said pivoting of said first housing being about said bar.
Claim 13
Dependent Claim
52 words
The capsule holder defined in claim 9 wherein said ears on said first housing engage said U-shaped bar comprising said latching means such that said cylindrically shaped cavity is held at an acute angle to said base to facilitate the manual placement of a capsule in said cavity of said first housing.
