Ring viewer

Claim 2

A ring viewer comprising: a housing consisting of two halves permanently sealed together, said housing including a substantially circular track formed integrally between said halves, a lens held in said housing in a position overlying said track, and a finger opening adapted to accommodate the finger of a wearer extending entirely through said housing and being surrounded by said track; an endless strip of film having a number of frames and corresponding perforations thereon moveably held in said track; a reflecting means mounted at an angle in said housing between said opening and said track in alignment with said lens and further openings formed in said housing above and below said film; and means in said housing to allow light to pass into said housing whereby said light will impinge on said reflecting means to pass through said further opening below said film, said further opening above said film and said lens to allow one of said frames on said film to be seen by a viewer.

Claim 3

The ring viewer of claim 1, further including a film advance mechanism mounted in said ring and cooperating with performations formed in said film to advance said film one frame at a time.

Claim 4

The ring viewer of claim 2 wherein said film advance mechanism comprises a single piece of resilient material, including an operating button, a front driving dog, and a rear stop dog to allow said film to be advanced in one direction only upon pressing on said button with sufficient force.

Claim 5

The ring viewer of claim 3 wherein said operating button is capable of being pushed into said ring from its rest position, said rear stop dog is fixed in said housing against movement along said track, and said front driving dog, when pressure is applied against said operating button to push said button into said ring, slides along on enlarged portion in said track, a predetermined distance, to advance said film one frame, and wherein said natural resilience of said advance mechanism will return said operating button and said front driving dog to their rest positions when said pressure is released from said button.

Claim 6

The ring viewer of claims 1, 2, 3, or 4 wherein said reflecting means in said housing is a mirror and said means to allow light to pass into said housing comprises an aperture passing through said housing and in alignment with said mirror.

Claim 7

A ring viewer comprising: two molded housing halves permanently welded together to form a ring housing; a finger opening formed in said housing adapted to accommodate the finger of a wearer; a track formed internally of said housing between said housing halves and surrounding said finger opening; an endless strip of film having a number of frames and corresponding perforations thereon moveably captured in said track; a light aperture formed in said housing, said light aperture extending entirely through one of said housing halves and being closed by a wall in said other housing half; a mirror mounted at a preselected angle in said light aperture to reflect light received from a light source; a lens captured between said housing halves and aligned with said mirror; two film openings formed in said housing in alignment with said lens and said mirror on either side of said track to allow said light reflected by said mirror to pass through a frame of said film to be seen by a viewer on said lens; and a unitary film advance mechanism held in said ring adjacent said film including means to move said film a frame at a time upon application of pressure thereto.

Claim 8

A ring viewer comprising: two molded housing halves permanently welded together to form a ring housing; a finger opening formed in said housing adapted to accommodate the finger of a wearer; a track formed internally of said housing between said housing halves and surrounding said finger opening; an endless strip of film having a number of frames and corresponding perforations thereon moveably captured in said track; a light aperture formed in said housing, said light aperture extending entirely through one of said housing halves and being closed by a wall in said other housing half; a mirror mounted at a preselected angle in said light aperture to reflect light received from a light source; a lens captured between said housing halves and aligned with said mirror; two film openings formed in said housing in alignment with said lens and said mirror on either side of said track to allow said light reflected by said mirror to pass through a frame of said film to be seen by a viewer on said lens; and a unitary film advance mechanism held in said ring adjacent said film including means to move said film a frame at a time upon application of pressure thereto.
