Abstract
Abstract A motion transmitting mechanism having a predetermined delay between input and output motion. Movement of the input is transmitted through a lost motion device, such as a spring, to an input piston. Movement of the input piston causes the displacement of a fluid medium which flows at a controlled rate through a restriction. Movement of the input piston is transmitted to an output piston through a lost motion device. Movement of the output piston causes the displacement of the fluid medium at a controlled rate through the restriction. The output moves simultaneously with the output piston.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
120 words
A motion transmitting mechanism comprising, a movable input member; a movable output member; first fluid displacing means; spring means between said input member and said first fluid displacing means for permitting lost motion therebetween; second fluid displacing means secured to said output member and having restriction means therein; and second spring means for permitting lost motion between said first and second fluid displacing means; said restriction means initially providing a time control for the fluid displaced by said first fluid displacing means and secondly providing a time control for the fluid displaced by said second fluid displacing means and cooperating with said first and second spring means to provide a time delay between movement of said input and output members.
Claim 2
Dependent Claim
120 words
A motion transmitting mechanism comprising, a movable input member; a movable output member; first fluid displacing means; spring means between said input member and said first fluid displacing means for permitting lost motion therebetween; second fluid displacing means secured to said output member and having restriction means therein; and second spring means for permitting lost motion between said first and second fluid displacing means; said restriction means initially providing a time control for the fluid displaced by said first fluid displacing means and secondly providing a time control for the fluid displaced by said second fluid displacing means and cooperating with said first and second spring means to provide a time delay between movement of said input and output members.
Claim 3
Dependent Claim
135 words
A motion transmitting mechanism comprising, a movable input member; a movable output member; first fluid displacing piston means; spring means between said input member and said first fluid displacing piston means for permitting lost motion and for transmitting a force therebetween; second fluid displacing piston means secured to said output member and having restriction means therein; and second spring means for permitting lost motion and for transmitting a force between said first and second fluid displacing means; said restriction means initially providing a time control for the fluid displaced by said first fluid displacing piston means and secondly providing a time control for the fluid displaced by said second fluid displacing piston means and cooperating with said first and second spring means to provide a time delay between movement of said input and output members.
Claim 4
Dependent Claim
135 words
A motion transmitting mechanism comprising, a movable input member; a movable output member; first fluid displacing piston means; spring means between said input member and said first fluid displacing piston means for permitting lost motion and for transmitting a force therebetween; second fluid displacing piston means secured to said output member and having restriction means therein; and second spring means for permitting lost motion and for transmitting a force between said first and second fluid displacing means; said restriction means initially providing a time control for the fluid displaced by said first fluid displacing piston means and secondly providing a time control for the fluid displaced by said second fluid displacing piston means and cooperating with said first and second spring means to provide a time delay between movement of said input and output members.
Claim 5
Dependent Claim
139 words
A motion transmitting mechanism comprising, an input member; an output member; housing means having a bore therein; first piston means slidably disposed in said bore; first spring means operatively connected between said input member and said first piston means for transmitting forces while permitting relative movement therebetween; second piston means secured to said output member and being slidably disposed in said first piston means; second spring means operatively connected between said first and second piston means for transmitting forces therebetween; a fluid filling said bore and said first piston means; and restriction means in said second piston means for initially controlling fluid flow in response to a force transmitted from said input member to said first piston means, and secondly controlling fluid flow in response to a force transmitted from said first piston means to said second piston means.
Claim 6
Dependent Claim
139 words
A motion transmitting mechanism comprising, an input member; an output member; housing means having a bore therein; first piston means slidably disposed in said bore; first spring means operatively connected between said input member and said first piston means for transmitting forces while permitting relative movement therebetween; second piston means secured to said output member and being slidably disposed in said first piston means; second spring means operatively connected between said first and second piston means for transmitting forces therebetween; a fluid filling said bore and said first piston means; and restriction means in said second piston means for initially controlling fluid flow in response to a force transmitted from said input member to said first piston means, and secondly controlling fluid flow in response to a force transmitted from said first piston means to said second piston means.
