Abstract
Abstract In a motion transformer for converting oscillatory to rotary motion, comprising (a) an enclosure including a base plate, a cover plate, and side members, all of which are substantially rigid, (b) a ratchet wheel within the enclosure mounted for both oscillatory and rotary motion, (c) a pair of stops limiting the amplitude of such oscillatory motion, (d) a ratchet pawl coacting with the ratchet wheel and a restraining member preventing retrograde rotation thereof to convert oscillatory motion thereof to uni-directional rotary motion, and (e) a liquid filling the space in said enclosure, a variable volume sealing chamber is bonded to the enclosure so as to hermetically seal the liquid in the enclosure and yet yield to thermal expansion and contraction of said liquid. The side members of the enclosure are preferably configured to fit in closely spaced relation about the ratchet wheel, to minimize the volume of the chamber within the enclosure.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
155 words
In a motion transformer for converting oscillatory motion to rotary motion comprising an enclosure including a base plate, a cover plate, and side members, all of which are substantially rigid, a ratchet wheel within said enclosure mounted both for oscillatory back-and-forth motion substantially on a diameter thereof and for rotary motion substantially about its center, a pair of stops fixedly mounted for limiting the amplitude of the oscillatory motion of the ratchet wheel within the enclosure, a ratchet pawl coacting with said ratchet wheel and a restraining member preventing retrograde rotation thereof to convert oscillatory motion of said ratchet wheel to unidirectional rotary motion, and a liquid filling the interior of said chamber about said ratchet wheel, stops, pawl and restraining member, tHe improvement comprising a variable volume sealing chamber bonded to said enclosure in communication with and hermetically sealing said liquid in the enclosure while yielding to thermal expansion and contraction of said liquid.
Claim 2
Dependent Claim
155 words
In a motion transformer for converting oscillatory motion to rotary motion comprising an enclosure including a base plate, a cover plate, and side members, all of which are substantially rigid, a ratchet wheel within said enclosure mounted both for oscillatory back-and-forth motion substantially on a diameter thereof and for rotary motion substantially about its center, a pair of stops fixedly mounted for limiting the amplitude of the oscillatory motion of the ratchet wheel within the enclosure, a ratchet pawl coacting with said ratchet wheel and a restraining member preventing retrograde rotation thereof to convert oscillatory motion of said ratchet wheel to unidirectional rotary motion, and a liquid filling the interior of said chamber about said ratchet wheel, stops, pawl and restraining member, tHe improvement comprising a variable volume sealing chamber bonded to said enclosure in communication with and hermetically sealing said liquid in the enclosure while yielding to thermal expansion and contraction of said liquid.
Claim 3
Dependent Claim
34 words
A motion transformer according to claim 1 wherein the variable-volume sealing chamber is formed by a yieldable diaphragm bonded to said enclosure and defining an expansion chamber communicating with the interior of said enclosure.
Claim 4
Dependent Claim
32 words
A motion transformer according to claim 1 wherein the variable volume sealing chamber comprises a bellows bonded to said enclosure and defining an expansion chamber communicating with the interior of said enclosure.
Claim 5
Dependent Claim
41 words
A motion transformer according to claim 2 wherein the diaphragm is bonded to the exterior of the cover plate and the expansion chamber defined thereby communicates with the interior of the enclosure through at least one opening in the cover plate.
Claim 6
Dependent Claim
39 words
A motion transformer according to claim 3 wherein the bellows is bonded to the exterior of the cover plate and the interior thereof communicates with the interior of the enclosure through at least one opening in the cover plate.
Claim 7
Dependent Claim
36 words
A motion transformer according to claim 1 wherein the side members of the enclosure are configured to fit in closely spaced relation about the ratchet wheel and thereby to minimize the volume of the enclosure interior.
Claim 8
Dependent Claim
49 words
A motion transformer according to claim 6 wherein the side members are configured to form a substantially cylindrical enclosure chamber only slightly larger in diameter than required to accommodate oscillatory motion of the ratchet wheel and to define at least one substantially tangential channel to receive the ratchet pawl.
Claim 9
Dependent Claim
30 words
A motion transformer according to claim 7 wherein the restraining member is a second pawl and the side members define a second substantially tangential channel to receive said second pawl.
Claim 10
Dependent Claim
32 words
A motion transformer according to claim 6 wherein the side members are formed with channels in which the stops are received and fixed in proper spaced relation relative to the ratchet wheel.
Claim 11
Dependent Claim
28 words
A motion transformer according to claim 6 wherein two substantially identically configured side members are bonded together and to the base and cover plates to form the enclosures.
