Abstract
Abstract The means of this invention comprises a rectangular cage means including spaced apart frame members adapted to receive the cycle frame therein. A plurality of length adjustable support members are secured to the frame members for supporting and positioning the cycle frame relative to the cage means. A hydraulic ram is selectively adjustably secured to the frame members as required and includes a rod portion adapted to engage the cycle frame to deflect or bend the same upon actuation of the ram means. A device is also disclosed for straightening the frame head portion of the cycle frame and for determining if the frame head has been properly vertically aligned and to determine if the frame has the proper rake angle. The method of straightening the cycle frame is also disclosed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
197 words
A means for straightening cycle frames comprising, a cage means including spaced-apart frame members adapted to receive the cycle frame therein, said cage means including vertically disposed side frame members, top frame members secured to and extending between the upper ends of said side frame members, and bottom frame members secured to and extending between the lower ends of said side frame members, length adjustable thrust support members for selective attachment to said, top, side and bottom frame members in force opposing disposition for opposing engagement with the cycle frame to securely lock said cycle frame to said cage means to prevent relative movement between said cycle frame and said cage means, and a power ram means for selective adjustable connection to said frame members and having an extendible rod adapted to engage and deflect portions of said cycle frame upon actuation of said ram means, at least some of said length adjustable thrust support members being positioned on said frame members so as to oppose the deflecting action of said ram means to maintain said cycle frame in position relative to said cage means as said power ram means deflects said portions of said cycle frame.
Claim 2
Dependent Claim
197 words
A means for straightening cycle frames comprising, a cage means including spaced-apart frame members adapted to receive the cycle frame therein, said cage means including vertically disposed side frame members, top frame members secured to and extending between the upper ends of said side frame members, and bottom frame members secured to and extending between the lower ends of said side frame members, length adjustable thrust support members for selective attachment to said, top, side and bottom frame members in force opposing disposition for opposing engagement with the cycle frame to securely lock said cycle frame to said cage means to prevent relative movement between said cycle frame and said cage means, and a power ram means for selective adjustable connection to said frame members and having an extendible rod adapted to engage and deflect portions of said cycle frame upon actuation of said ram means, at least some of said length adjustable thrust support members being positioned on said frame members so as to oppose the deflecting action of said ram means to maintain said cycle frame in position relative to said cage means as said power ram means deflects said portions of said cycle frame.
Claim 3
Dependent Claim
22 words
The means of claim 1 wherein at least some of said length adjustable thrust members are pivotally secured to said frame members.
Claim 4
Dependent Claim
21 words
The means of claim 1 wherein at least some of said frame members are selectively pivotally secured to said cage means.
Claim 5
Dependent Claim
25 words
The means of claim 1 wherein at least some of said frame members are selectively positioned on said cage means relative to the cycle frame.
Claim 6
Dependent Claim
155 words
A means for straightening cycle frames comprising, a cage means including spaced apart frame members adapted to receive the cycle frame therein, length adjustable support members for selective attachment to said frame members for engagement with the cycle frame to support the cycle frame relative to said cage means, and a power ram means for selective adjustable connection to said frame members and having an extendible rod adapted to engage and deflect portions of said cycle frame upon actuation of said ram means, an elongated member for insertion into the frame head of the cycle frame, said elongated member having upper and lower portions positioned above and below the frame head respectively, said power ram having means thereon for selective engagement with the upper and lower portions of said elongated member, at least one of said length adjustable members having means thereon for selective engagement with the upper and lower portions of said elongated member.
Claim 7
Dependent Claim
155 words
A means for straightening cycle frames comprising, a cage means including spaced apart frame members adapted to receive the cycle frame therein, length adjustable support members for selective attachment to said frame members for engagement with the cycle frame to support the cycle frame relative to said cage means, and a power ram means for selective adjustable connection to said frame members and having an extendible rod adapted to engage and deflect portions of said cycle frame upon actuation of said ram means, an elongated member for insertion into the frame head of the cycle frame, said elongated member having upper and lower portions positioned above and below the frame head respectively, said power ram having means thereon for selective engagement with the upper and lower portions of said elongated member, at least one of said length adjustable members having means thereon for selective engagement with the upper and lower portions of said elongated member.
Claim 8
Dependent Claim
43 words
The means of claim 5 wherein a vertical alignment and rake angle gauge is provided for insertion into the frame head, said gauge comprising means indicating the vertical attitude of said frame head and for indicating the rake angle of the frame head.
Claim 9
Dependent Claim
12 words
The means of claim 1 wherein said cage means is wheel supported.
