Abstract
Abstract A combined integral component enclosure and track roller frame for a track-type vehicle includes an elongated inverted U-shaped housing with a tunnel forming bight portion and a pair of spaced leg portions, a plurality of elongated wall members individually secured to the leg portions of the housing and forming therewith a pair of substantially parallel box beams, and a stiffening cross plate disposed within the housing between the box beams to form a track roller frame having maximum strength and resistance to distortion.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
159 words
A combined integral component Enclosure and track roller frame, for a track-type vehicle supported thereon by a plurality of rollers mounted on the frame, with an endless track chain peripherally engaged with the rollers, and with a recoil mechanism applying tension to the track chain, comprising; an elongated inverted U-shaped housing having a tunnel forming bight portion and a pair of spaced leg portions; elongated roller mounting means including a pair of symmetrically oppositely outwardly facing L-shaped angle members and additional connector wall members individually secured to their respectively adjacent angled members in outwardly extended channular forming relationship therewith for attachment to said leg portions of the housing forming therewith a pair of substantially parallel fully enclosed box beams; and an elongated cross-plate disposed within said housing substantially horizontally between said box beams to form a tunnel-like enclosure which contains and protects such recoil mechanism while also providing a track roller frame having maximum strength and resistance to distortion.
Claim 2
Dependent Claim
159 words
A combined integral component Enclosure and track roller frame, for a track-type vehicle supported thereon by a plurality of rollers mounted on the frame, with an endless track chain peripherally engaged with the rollers, and with a recoil mechanism applying tension to the track chain, comprising; an elongated inverted U-shaped housing having a tunnel forming bight portion and a pair of spaced leg portions; elongated roller mounting means including a pair of symmetrically oppositely outwardly facing L-shaped angle members and additional connector wall members individually secured to their respectively adjacent angled members in outwardly extended channular forming relationship therewith for attachment to said leg portions of the housing forming therewith a pair of substantially parallel fully enclosed box beams; and an elongated cross-plate disposed within said housing substantially horizontally between said box beams to form a tunnel-like enclosure which contains and protects such recoil mechanism while also providing a track roller frame having maximum strength and resistance to distortion.
Claim 3
Dependent Claim
120 words
A combined integral component enclosure and track roller frame, for a track-type vehicle, comprising: an elongated inverted U-shaped housing having a tunnel forming bight portion and a pair of spaced leg portions integrally providing a pair of external side walls; elongated roller mounting means including a pair of top wall members and a pair of symmetrically oppositely outwardly facing L-shaped angle members integrally providing a pair of internal side walls and a pair of bottom wall members secured to said external side walls of the housing for forming therewith a pair of substantially parallel box beams; and stiffener means disposed within said housing between said box beams to form a track roller frame having maximum strength and resistance to distortion.
Claim 4
Dependent Claim
120 words
A combined integral component enclosure and track roller frame, for a track-type vehicle, comprising: an elongated inverted U-shaped housing having a tunnel forming bight portion and a pair of spaced leg portions integrally providing a pair of external side walls; elongated roller mounting means including a pair of top wall members and a pair of symmetrically oppositely outwardly facing L-shaped angle members integrally providing a pair of internal side walls and a pair of bottom wall members secured to said external side walls of the housing for forming therewith a pair of substantially parallel box beams; and stiffener means disposed within said housing between said box beams to form a track roller frame having maximum strength and resistance to distortion.
Claim 5
Dependent Claim
50 words
The combined integral component enclosure and track roller frame of claim 2 wherein said stiffener means is an elongated cross plate spannably formed as a unit with said top wall member of each box beam and which is marginally secured to said external side walls and said internal side walls.
Claim 6
Dependent Claim
112 words
A combined integral component enclosure and track roller frame, for a track-type vehicle, comprising; an elongated inverted U-shaped housing having depending legs individually providing an intermediate portion and a lower surface portion; an elongated cross plate oppositely marginally secured to said intermediate portion of each of said legs in generally horizontally bridging stiffening relation there-between thereby forming with said housing a track recoil mechanism receiving protective enclosure; and a pair of symmetrically disposed oppositely outwardly facing L-shaped angle members secured to said elongated cross plate and said lower surface portion of said legs and forming therewith a pair of substantially parallel elongated box beams for optimum strength and maximum resistance to distortion.
Claim 7
Dependent Claim
112 words
A combined integral component enclosure and track roller frame, for a track-type vehicle, comprising; an elongated inverted U-shaped housing having depending legs individually providing an intermediate portion and a lower surface portion; an elongated cross plate oppositely marginally secured to said intermediate portion of each of said legs in generally horizontally bridging stiffening relation there-between thereby forming with said housing a track recoil mechanism receiving protective enclosure; and a pair of symmetrically disposed oppositely outwardly facing L-shaped angle members secured to said elongated cross plate and said lower surface portion of said legs and forming therewith a pair of substantially parallel elongated box beams for optimum strength and maximum resistance to distortion.
Claim 8
Dependent Claim
106 words
A combined integral component enclosure and track roller frame, for a track-type vehicle, comprising; an elongated inverted U-shaped housing having depending legs individually providing an intermediate portion and a lower surface portion; symmetrically disposed oppositely outwardly facing channel means individually secured to said intermediate and said lower surface portion of each of said legs and forming therewith a pair of substantially parallel elongated box beams; and an elongated cross plate oppositely marginally secured to said box beams in generally horizontal stiffening relation therebetween to form a recoil mechanism receiving protective enclosure while also providing a track roller frame having a substantial section modulus for improved strength.
Claim 9
Dependent Claim
106 words
A combined integral component enclosure and track roller frame, for a track-type vehicle, comprising; an elongated inverted U-shaped housing having depending legs individually providing an intermediate portion and a lower surface portion; symmetrically disposed oppositely outwardly facing channel means individually secured to said intermediate and said lower surface portion of each of said legs and forming therewith a pair of substantially parallel elongated box beams; and an elongated cross plate oppositely marginally secured to said box beams in generally horizontal stiffening relation therebetween to form a recoil mechanism receiving protective enclosure while also providing a track roller frame having a substantial section modulus for improved strength.
