Abstract
Abstract A motion converter device capable of converting continuous rotary input motion to cyclic linear motion and capable of accomplishing the reversal thereof from cyclic linear motion to continuous rotary motion including means for substantially smoothly obtaining the conversion. The unit includes a set of gear trains having gears of a selected shape and which gear trains are intermeshed from either a single rotary shaft or a plurality of linked output shafts which interwork to convert the rotary motion of the single shaft to oscillatory or linear motion of the output shafts or will, in the reverse of this procedure, convert a linear input to the plurality of shafts to rotary motion of the single shaft.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
154 words
A motion converting device including: a. a housing defining a gear receiving cavity therein; b. a first shaft member arranged for rotation and extending into said cavity; c. a first pair of gear members arranged on said first shaft within said cavity for rotation with said first shaft, said gear member being arranged for rotation on said shaft; d. at least one second shaft extending into said cavity and being arranged for rotation therein; e. a second pair of gear members arranged on said second shaft within said cavity for rotation with said second shaft, said gear members being arranged for engaging said first pair of gear members; f. said second shaft having a splined driving section and being longitudinally shiftable with respect to one of said second pair of gear members; and, g. said second shaft having a threaded section and the other of said second pair of gear members threadably arranged thereon.
Claim 2
Dependent Claim
154 words
A motion converting device including: a. a housing defining a gear receiving cavity therein; b. a first shaft member arranged for rotation and extending into said cavity; c. a first pair of gear members arranged on said first shaft within said cavity for rotation with said first shaft, said gear member being arranged for rotation on said shaft; d. at least one second shaft extending into said cavity and being arranged for rotation therein; e. a second pair of gear members arranged on said second shaft within said cavity for rotation with said second shaft, said gear members being arranged for engaging said first pair of gear members; f. said second shaft having a splined driving section and being longitudinally shiftable with respect to one of said second pair of gear members; and, g. said second shaft having a threaded section and the other of said second pair of gear members threadably arranged thereon.
Claim 3
Dependent Claim
24 words
The structure set forth in claim 1 and said first pair of gear members including elliptical gears being eccentrically arranged on said first shaft.
Claim 4
Dependent Claim
25 words
The structure set forth in claim 1 and said first pair of said gear members being mounted on said first shaft in 180° opposed relation.
Claim 5
Dependent Claim
54 words
The structure set forth in claim 1 and said splined section of said second shaft including externally formed splines on said shaft, internally formed splines on said engaging gear and ball members arranged in mating relation therebetween to permit relative longitudinal motion between said shaft and said gear while maintaining the rotational motion thereof.
Claim 6
Dependent Claim
56 words
The structure set forth in claim 1 and said threaded section of said second shaft including a ball nut member surrounding the same and connected to said gear arranged therearound to provide longitudinal motion of said second shaft upon rotation of said gear and providing rotation of said gear upon longitudinal motion of said second shaft.
Claim 7
Dependent Claim
25 words
The structure set forth in claim 1 and at least a pair of said second shafts, each such shaft having pairs of second gears thereon.
Claim 8
Dependent Claim
32 words
The structure set forth in claim 6 and said gears on said second shafts including elliptical gears, each of said gears being in constant mesh with said gears on said first shaft.
Claim 9
Dependent Claim
19 words
The structure set forth in claim 1 and means for imparting and receiving linear motion of said second shafts.
Claim 10
Dependent Claim
55 words
The structure set forth in claim 8 and said means for imparting and receiving linear motion of said second shafts including a piston member arranged on said shafts, a cylinder surrounding said piston for actuation therein and fluid control means directing and receiving fluid to and from said cylinder on opposite sides of said piston.
Claim 11
Dependent Claim
47 words
The structure set forth in claim 1 and a plurality of second shafts arcuately spaced about said first shaft and each of said second shafts having pairs of second gear members thereon which second gear members are in constant mesh with said first pair of gear members.
Claim 12
Dependent Claim
24 words
The structure set forth in claim 1 and said first pair of gear members including oval gears being concentrically arranged on said first shaft.
Claim 13
Dependent Claim
24 words
The structure set forth in claim 1 and said first pair of gear members including circular gears being eccentrically arranged on said first shaft.
