Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
270 words
An apparatus for integrally removing a track plate and spikes secured to a tie, comprising: (a) three parallel spaced longitudinally extending frame members, each of said frame members having opposed ends; (b) bracket means secured to generally said frame members ends for fixedly aligning said frame members for defining a frame thereby; (c) cylinder and piston means secured to said bracket means extending transversely of said frame and including a tie contacting portion and being adapted for reciprocally displacing said frame; (d) each of said frame members having a pair of spaced apertures and each aperture of a frame member being aligned with an aperture of an adjacent frame member; (e) a pair of arms pivotally secured to said frame and each of said arms having upwardly and downwardly extending portions, each of said arms including a pair of arm members and having one of said frame members disposed between said arm members; (f) pin means pivotally securing said arms to said frame; (g) opposed piston cylinder and piston means pivotally secured to said upwardly extending portion of each of said arms for reciprocally pivoting said arms; and, (h) opposed crowbar means secured to said downwardly extending portion of said arms each of said crowbar means including a tie contacting portion and a track plate contacting portion whereby said track plate contacting portion adapted for being positioned between said track plate and said tie by pivoting of said arms for displacing said track plate and said spikes and whereby said cylinder and piston means upwardly displacing said frame for integrally removing said track plate and said spikes from said frame.
Claim 2
Independent Claim
270 words
An apparatus for integrally removing a track plate and spikes secured to a tie, comprising: (a) three parallel spaced longitudinally extending frame members, each of said frame members having opposed ends; (b) bracket means secured to generally said frame members ends for fixedly aligning said frame members for defining a frame thereby; (c) cylinder and piston means secured to said bracket means extending transversely of said frame and including a tie contacting portion and being adapted for reciprocally displacing said frame; (d) each of said frame members having a pair of spaced apertures and each aperture of a frame member being aligned with an aperture of an adjacent frame member; (e) a pair of arms pivotally secured to said frame and each of said arms having upwardly and downwardly extending portions, each of said arms including a pair of arm members and having one of said frame members disposed between said arm members; (f) pin means pivotally securing said arms to said frame; (g) opposed piston cylinder and piston means pivotally secured to said upwardly extending portion of each of said arms for reciprocally pivoting said arms; and, (h) opposed crowbar means secured to said downwardly extending portion of said arms each of said crowbar means including a tie contacting portion and a track plate contacting portion whereby said track plate contacting portion adapted for being positioned between said track plate and said tie by pivoting of said arms for displacing said track plate and said spikes and whereby said cylinder and piston means upwardly displacing said frame for integrally removing said track plate and said spikes from said frame.
