Abstract
Abstract An ambulatory worker toy having a wind-up spring motor within a housing which includes a head casing movably mounted on a torso casing from which fixed and movable arm members extend. Two movably mounted leg members are connected to the spring motor via an ambulatory transmission mechanism to periodically raise and shift the leg members to propel the toy sideways in a walking motion. A tool movement transmission mechanism driven by the spring motor moves the movable arm member and a toy broom attached thereto to simulate a sweeping action. Finally, an oscillatory transmission mechanism driven by the spring motor periodically pumps an internal whistle mechanism and moves the head casing in simulation of a whistling worker. The net effect of the various transmission mechanisms is to present a toy which is powered by a single spring motor but which nevertheless simulates a sweeping worker which whistles as it walks.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
171 words
An ambulatory toy, comprising: a chassis; two leg members each having a foot member mounted at the bottom end thereof, the top end of each leg member being movably mounted on said chassis; a power source mounted on said chassis, said power source including a rotatable gear, the axis of said gear being substantially perpendicular to a line connecting said foot members; ambulatory transmission mechanism means operatively connecting said leg members to said power source for periodically moving said leg members vertically and angularly to propel said chassis sideways along a line connecting said foot members, said ambulatory transmission mechanism means including two pegs, each peg being affixed to a corresponding leg member between the top and bottom ends thereof, and two corresponding rotatably mounted elements operatively connected to said gear at different points on the periphery thereof, each rotatably mounted element having an offset hole therein to receive the corresponding peg, the axis of rotation of each rotatably mounted element being substantially perpendicular to a line connecting said foot members.
Claim 2
Dependent Claim
171 words
An ambulatory toy, comprising: a chassis; two leg members each having a foot member mounted at the bottom end thereof, the top end of each leg member being movably mounted on said chassis; a power source mounted on said chassis, said power source including a rotatable gear, the axis of said gear being substantially perpendicular to a line connecting said foot members; ambulatory transmission mechanism means operatively connecting said leg members to said power source for periodically moving said leg members vertically and angularly to propel said chassis sideways along a line connecting said foot members, said ambulatory transmission mechanism means including two pegs, each peg being affixed to a corresponding leg member between the top and bottom ends thereof, and two corresponding rotatably mounted elements operatively connected to said gear at different points on the periphery thereof, each rotatably mounted element having an offset hole therein to receive the corresponding peg, the axis of rotation of each rotatably mounted element being substantially perpendicular to a line connecting said foot members.
Claim 3
Dependent Claim
43 words
The ambulatory toy of claim 1, wherein said chassis has vertically disposed slots therein corresponding to each leg member, and wherein the top end of each leg member is movably mounted on said chassis by pegs movably extending into the vertically disposed slots.
Claim 4
Dependent Claim
54 words
The toy of claim 1, wherein said chassis is mounted in a torso casing having a first arm member movably mounted thereon, and further comprising a toy tool operatively connected to said first arm member and tool movement transmission mechanism means operatively connecting said power source and said toy tool for moving said tool.
Claim 5
Dependent Claim
53 words
The toy of claim 3, wherein said toy tool has a handle with a hole therein and wherein said tool movement transmission mechanism means comprises a rotatably mounted element operatively connected to said power source, said rotatably mounted element having an offset peg projecting therefrom and extending through the hole in said handle.
Claim 6
Dependent Claim
53 words
The toy of claim 5, wherein said toy tool is a toy broom having a plurality of resilient bristles extending therefrom, and further comprising a second arm member fixedly attached to said torso casing and having an opening in the hand end thereof through which the handle of said toy broom movably extends.
Claim 7
Dependent Claim
44 words
The toy of claim 1, further comprising a whistle element mounted on said chassis, a bellows pneumatically connected to said whistle element, and oscillatory transmission mechanism means operatively connecting said power source and said bellows for pumping said bellows to excite said whistle element.
Claim 8
Dependent Claim
26 words
The toy of claim 6, further comprising a pivotably mounted head casing, and wherein said oscillatory transmission mechanism further comprises means for pivoting said head casing.
Claim 9
Dependent Claim
161 words
An ambulatory toy, comprising: a torso having a first arm member movably mounted thereon; a chassis mounted in said torso; two leg members each having a foot member mounted at the bottom end thereof, the top end of each leg member being movably mounted on said chassis; a power source mounted on said chassis; ambulatory transmission mechanism means operatively connecting said leg members to said power source for periodically moving said leg members vertically and angularly to propel said chassis sideways along a line connecting said foot members; a toy tool operatively connected to said first arm member, said toy tool having a handle with a hole therein; and tool movement transmission mechanism means operatively connecting said power source and said toy for moving said tool, said tool movement transmission mechanism means comprising a rotatably mounted element operatively connected to said power source, said rotatably mounted element having an offset peg projecting therefrom and extending through the hole in said handle.
Claim 10
Dependent Claim
161 words
