Oscillating cut-out tool

Claim 2

An oscillating cut-out tool used for removing a windshield from a vehicle, the tool comprising: a motor having a motor drive shaft; an eccentric attached to said drive shaft; a yoke having a yoke neck and two outwardly extending yoke arms, said eccentric disposed between said yoke arms, said eccentric imparting an oscillating motion on said yoke when said eccentric is rotated by said drive shaft; an oscillating shaft having one end attached to said yoke neck, said yoke imparting an oscillating motion about an axis along the length of the oscillating shaft and through the center thereof; and an "L" shaped oscillating cutting blade with the long leg thereof attached to the periphery of said oscillating shaft such that the axis of rotation of said shaft with attached blade passes through substantially the mid-portion of the short leg of the "L" shaped blade.

Claim 3

The tool as described in claim 1 wherein said eccentric is an eccentric sleeve and a ball bearing having an inner race, an outer race and rolling balls therebetween, said sleeve disposed around said drive shaft and attached thereto, said sleeve also mounted to the inner race of said ball bearing, said yoke arms disposed around the outer race of said ball bearing.

Claim 4

An oscillating cut-out tool used for removing a windshield from a vehicle, the tool comprising: a motor having a motor drive shaft; a rear housing attached to one end of said motor for receiving switch means therein for turning said motor on and off; a front housing attached to the other end of said motor and housing said drive shaft therein; an eccentric sleeve disposed around the end of said motor drive shaft and attached thereto; a ball bearing having an inner race, an outer race, and rolling balls therebetween, the inner race of said ball bearing attached to the outer circumference of said eccentric sleeve; a yoke having a yoke neck and outwardly extending yoke arms, the outer race of said ball bearing disposed between said yoke arms, said ball bearing imparting an oscillating motion on said yoke when said eccentric sleeve and said ball bearing are rotated by said drive shaft; a bushing mounted in said front housing; an oscillating shaft mounted in said bushing and pivoted thereon, one end of said oscillating shaft attached to said yoke neck, said yoke imparting an oscillating motion about an axis along the length of the oscillating shaft and through the center thereof; and an "L" shaped oscillating cutting blade with the long leg thereof attached to the periphery of said oscillating shaft such that the axis of rotation of said shaft with attached blade passes through substantially the mid-portion of the short leg of the "L" shaped blade.

Claim 5

An oscillating cut-out tool used for removing a windshield from a vehicle, the tool comprising: a motor having a motor drive shaft; a rear housing attached to one end of said motor for receiving switch means therein for turning said motor on and off; a front housing attached to the other end of said motor and housing said drive shaft therein; an eccentric sleeve disposed around the end of said motor drive shaft and attached thereto; a ball bearing having an inner race, an outer race, and rolling balls therebetween, the inner race of said ball bearing attached to the outer circumference of said eccentric sleeve; a yoke having a yoke neck and outwardly extending yoke arms, the outer race of said ball bearing disposed between said yoke arms, said ball bearing imparting an oscillating motion on said yoke when said eccentric sleeve and said ball bearing are rotated by said drive shaft; a bushing mounted in said front housing; an oscillating shaft mounted in said bushing and pivoted thereon, one end of said oscillating shaft attached to said yoke neck, said yoke imparting an oscillating motion about an axis along the length of the oscillating shaft and through the center thereof; and an "L" shaped oscillating cutting blade with the long leg thereof attached to the periphery of said oscillating shaft such that the axis of rotation of said shaft with attached blade passes through substantially the mid-portion of the short leg of the "L" shaped blade.

Claim 6

The tool as described in claim 3 further including a cable attached to said front housing and having a handle attached thereto, said handle used for guiding said oscillating cutting blade when the cut-out tool is used for removing a windshield.
