Abstract
Abstract A mechanism for transmitting the power output of a music box to an ornament supported thereon, wherein the output shaft of the music box rotates an eccentric stub that is engaged within a slide link supported for vertical movement on a pair of guide rods. The ornament is supported by a tappet rod having a lower end secured to either the slide link or the drive stub, so that operation of the music box will impart the desired movement to the ornament.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
173 words
A mechanism for transmitting the power output of a power drive source to an ornament for imparting a desired movement thereto, which mechanism comprises: (a) a drive wheel for rotation by a power output shaft of a power drive source, the drive wheel including an eccentrically disposed drive stub secured thereto; (b) a pair of stationary parallel guide rods; (c) a slide link provided with a longitudinal slot engageable by the drive stub and a pair of spaced holes therethrough at opposite ends of the link, each hole being configured and sized for slidably receiving a guide rod therethrough to support and guide the link during reciprocating movement along the guide rods; (d) a tappet rod for supporting an ornament at one end thereof, with the other end of the tappet rod being rotatably secured to the drive stub; and (e) whereby when the drive wheel is rotated, the slide link is caused to reciprocate along the guide rods and the drive stubs imparts simulataneous reciprocating and pivoting movements to the tappet rod.
Claim 2
Dependent Claim
173 words
A mechanism for transmitting the power output of a power drive source to an ornament for imparting a desired movement thereto, which mechanism comprises: (a) a drive wheel for rotation by a power output shaft of a power drive source, the drive wheel including an eccentrically disposed drive stub secured thereto; (b) a pair of stationary parallel guide rods; (c) a slide link provided with a longitudinal slot engageable by the drive stub and a pair of spaced holes therethrough at opposite ends of the link, each hole being configured and sized for slidably receiving a guide rod therethrough to support and guide the link during reciprocating movement along the guide rods; (d) a tappet rod for supporting an ornament at one end thereof, with the other end of the tappet rod being rotatably secured to the drive stub; and (e) whereby when the drive wheel is rotated, the slide link is caused to reciprocate along the guide rods and the drive stubs imparts simulataneous reciprocating and pivoting movements to the tappet rod.
Claim 3
Dependent Claim
26 words
The mechanism of claim 1 further including a ball joint assembly supporting the tappet rod between the ends thereof for the simultaneous reciprocating and pivoting movements.
Claim 4
Dependent Claim
55 words
The mechanism of claim 2 wherein the ball joint assembly includes a socket, a ball segment disposed within the socket and provided with a central channel configured and sized for slidably receiving the tappet rod therethrough and a bushing for securing the socket and ball segment to an aperture of a casing enclosing the mechanism.
Claim 5
Dependent Claim
21 words
The mechanism of claim 1 wherein the guide rods are provided with spring means for imparting bias to the slide link.
Claim 6
Dependent Claim
13 words
The mechanism of claim 1 wherein the slide link is of integral construction.
Claim 7
Dependent Claim
30 words
The mechanism of claim 1 wherein the slide link includes an elongate member and a U-shaped member, with the elongate member being secured to the legs of the U-shaped member.
Claim 8
Dependent Claim
141 words
A mechanism for transmitting the power output of a power drive source to a pair of ornaments for imparting desired movements thereto, which mechanism comprises: (a) a pair of drive wheels for rotation by a power drive source, each drive wheel including an eccentrically disposed drive stub secured thereto; (b) a pair of stationary guide means; (c) a pair of slide links, each link being engaged by a drive stub and a guide means; (d) a pair of tappet rods, each tappet rod for supporting an ornament thereon, with an end of each tappet rod being rotatably secured to a drive stub; and (e) whereby when the drive wheels are rotated by the power drive source, each slide link is caused to reciprocate along the guide means and each drive stub imparts simultaneous reciprocating and pivoting movements to the tappet rod.
Claim 9
Dependent Claim
141 words
A mechanism for transmitting the power output of a power drive source to a pair of ornaments for imparting desired movements thereto, which mechanism comprises: (a) a pair of drive wheels for rotation by a power drive source, each drive wheel including an eccentrically disposed drive stub secured thereto; (b) a pair of stationary guide means; (c) a pair of slide links, each link being engaged by a drive stub and a guide means; (d) a pair of tappet rods, each tappet rod for supporting an ornament thereon, with an end of each tappet rod being rotatably secured to a drive stub; and (e) whereby when the drive wheels are rotated by the power drive source, each slide link is caused to reciprocate along the guide means and each drive stub imparts simultaneous reciprocating and pivoting movements to the tappet rod.
