Abstract
Abstract A throttle control assembly for lawnmowers and similar power-operated equipment, such assembly consisting essentially of (1) a mounting member permanently affixed to the flexible casing for the throttle control wire and adapted to be secured to the handle of the power equipment, and (2) an elongated cover that may be easily connected to the end of the control wire and then snapped into operative position over the mounting member. When the parts are so coupled, the cover is readily slidable upon the mounting member (which it conceals and protects) to control engine speed but is securely locked against detachment from that mounting member. A speed indicator formed as an integral part of the mounting member projects through an elongated slot in the cover, and indicia upon the cover aligned with the indicator provide clear and accurate representations of throttle settings.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
197 words
A throttle control assembly for lawnmowers and other power-operated equipment, comprising a throttle control wire slidably carried in a flexible tubular casing with its ends projecting beyond the ends of said casing; a mounting member secured to one of said ends of said casing and having an undersurface adapted to be affixed to said equipment; said mounting member having generally parallel sides and a pair of longitudinal ribs projecting laterally from said sides with smooth, elongated, upper surfaces; and an elongated cover having integral top and side walls defining a downwardly-opening cavity for receiving said mounting member; said cover being substantially longer than said mounting member and said side walls thereof providing elongated downwardly-facing bearing surfaces within said cavity for slidably engaging the upper surfaces of said ribs; retention means formed integrally with said side walls of said cover for retaining said cover upon said mounting member; means provided by said cover for securing the same to a portion of said wire projecting from the end of said casing secured to said mounting member; and a knob provided by said cover to facilitate manually sliding said cover longitudinally into selected operating positions relative to said mounting member.
Claim 2
Dependent Claim
197 words
A throttle control assembly for lawnmowers and other power-operated equipment, comprising a throttle control wire slidably carried in a flexible tubular casing with its ends projecting beyond the ends of said casing; a mounting member secured to one of said ends of said casing and having an undersurface adapted to be affixed to said equipment; said mounting member having generally parallel sides and a pair of longitudinal ribs projecting laterally from said sides with smooth, elongated, upper surfaces; and an elongated cover having integral top and side walls defining a downwardly-opening cavity for receiving said mounting member; said cover being substantially longer than said mounting member and said side walls thereof providing elongated downwardly-facing bearing surfaces within said cavity for slidably engaging the upper surfaces of said ribs; retention means formed integrally with said side walls of said cover for retaining said cover upon said mounting member; means provided by said cover for securing the same to a portion of said wire projecting from the end of said casing secured to said mounting member; and a knob provided by said cover to facilitate manually sliding said cover longitudinally into selected operating positions relative to said mounting member.
Claim 3
Dependent Claim
15 words
The assembly of claim 1 in which said knob is integrally formed with said cover.
Claim 4
Dependent Claim
18 words
The assembly of claim 2 in which said knob extends upwardly from the top wall of said cover.
Claim 5
Dependent Claim
32 words
The assembly of claim 1 in which said means for securing said cover to said wire comprises an opening formed in said cover to receive and retain said end of said wire.
Claim 6
Dependent Claim
36 words
The assembly of claim 1 in which said retention means comprises a plurality of integral barbs spaced below said downwardly-facing bearing surfaces of said cover for retaining said ribs between said bearing surfaces and said barbs.
Claim 7
Dependent Claim
25 words
The assembly of claim 1 in which said mounting member is formed of metal and is insert diecast about said one end of said casing.
Claim 8
Dependent Claim
43 words
The assembly of claim 1 in which said top wall of said cover is provided with a longitudinal slit; said mounting member having indicator means projecting upwardly through said slit for indicating the setting of said cover in relation to said mounting member.
Claim 9
Dependent Claim
27 words
The assembly of claim 7 in which said top wall is provided with indicia adjacent said slit for relating the position of said indicator to engine speed.
Claim 10
Dependent Claim
46 words
The assembly of claim 1 in which said cover also includes at least one integrally-formed spring finger extending from said top wall alongside said mounting member; and detent means provided by said mounting member at selected positions along the length thereof for engaging said spring finger.
Claim 11
Dependent Claim
47 words
The assembly of claim 9 in which a pair of said spring fingers extend from said top wall along opposite sides of said mounting member above said ribs; said detent means comprising ridges projecting laterally from opposite sides of said mounting member for engagement with said fingers.
