Abstract
Abstract A readily portable metal lath slitting machine having a retractable carriage crosswise of its heavier end equipped with lever means for convenience and ease of shifting the carriage between extended and retracted positions. The machine slits one or several layers of lath simultaneously with ease. Extendable work-supporting tables provide ample space for accommodating large sheets of stock material and fold compactly against the machine into a size permitting the machine to be rolled by one man through normal-size doors and into a conventional passenger elevator.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
135 words
A self-contained, compact metal lath cutting machine readily rolled from place-to-place by one man, said machine having a main frame pivotally supported at one end on wheel means, first and second stock-supporting means crosswise of the opposite ends of said main body, said first stock-supporting means being generally horizontal and said second stock-supporting means being inclined downwardly and rearwardly from a level adjacent one upper edge of said main frame to support severed stock in an inclined plane generally below said first stock-supporting means, and a pair of oppositely driven rotary metal cutting disks having their rim edges overlapped and in close running face-to-face fit in a vertical plane passing between said first and second stocksupporting means and effective to sever metallic lath as the same passes between the overlapped edges of said cutter disks.
Claim 2
Dependent Claim
135 words
A self-contained, compact metal lath cutting machine readily rolled from place-to-place by one man, said machine having a main frame pivotally supported at one end on wheel means, first and second stock-supporting means crosswise of the opposite ends of said main body, said first stock-supporting means being generally horizontal and said second stock-supporting means being inclined downwardly and rearwardly from a level adjacent one upper edge of said main frame to support severed stock in an inclined plane generally below said first stock-supporting means, and a pair of oppositely driven rotary metal cutting disks having their rim edges overlapped and in close running face-to-face fit in a vertical plane passing between said first and second stocksupporting means and effective to sever metallic lath as the same passes between the overlapped edges of said cutter disks.
Claim 3
Dependent Claim
80 words
The combination defined in claim 1 characterized in that said cutting disks have thick beveled edges with the high side of the bevel terminating on the adjacent faces of said disks, and said disks having their axes vertically spaced from one another and the blade more remote from said horizontal stock supporting surface being uppermost whereby the beveled edge on the lower side thereof is disposed to deflect slit portions of sheet material downwardly toward said inclined stock supporting surface.
Claim 4
Dependent Claim
45 words
The combination defined in claim 1 characterized in that said cutter disks have thick beveled edges and are mounted on vertically spaced parallel shafts with the beveled edges disposed to deflect freshly slit portions of sheet material apart to prevent hang-up between said slit edges.
Claim 5
Dependent Claim
119 words
A self-contained metal lath cutting machine supported at one end on wheels means and adapted to be rolled from place to place by one man, said machine having a rigid frame supporting driving motor means connected to drive a pair of notched overlapping metal cutter blades all located near the carriage-supported end of said machine, and first and second lath supporting means located to either side of a vertical plane traversing the axis of said cutter blades, said first lath supporting means being horizontal and located generally in the cutting plane of the overlapped edges of said cutter blades and said second lath supporting means being inclined downwardly and rearwardly from the forward portion of said first supporting surface.
Claim 6
Dependent Claim
119 words
A self-contained metal lath cutting machine supported at one end on wheels means and adapted to be rolled from place to place by one man, said machine having a rigid frame supporting driving motor means connected to drive a pair of notched overlapping metal cutter blades all located near the carriage-supported end of said machine, and first and second lath supporting means located to either side of a vertical plane traversing the axis of said cutter blades, said first lath supporting means being horizontal and located generally in the cutting plane of the overlapped edges of said cutter blades and said second lath supporting means being inclined downwardly and rearwardly from the forward portion of said first supporting surface.
Claim 7
Dependent Claim
88 words
A self-contained power-driven lath cutting machine as defineD in claim 4 characterized in that said wheel means has an axis extending crosswise of one end of said main frame and includes means for shifting said wheel means between the retracted and extended positions thereof with the axis thereof so positioned relative to the longitudinal center of gravity of said machine that one man can easily apply a lifting force to the other end of said machine and tilt the same upwardly about the axis of said wheel means.
Claim 8
Dependent Claim
96 words
A slitting machine as defined in claim 4 characterized in the provision of a plurality of collapsible work-supporting table means operatively connected to said main frame and including means permitting said table means to be stored compactly against said main frame when not needed and to be extended to workpiece supporting positions when said machine is in use, said machine when said table means are stored thereagainst being readily movable through conventional office-size doorways and through the conventional size doors of passenger elevators for convenience in moving said machine from floor-to-floor as installation of lathing progresses.
Claim 9
Dependent Claim
70 words
A slitting machine as defined in claim 6 characterized in that said plurality of collapsible table means includes a first and second table means extendable outwardly and forwardly from the forward edge of said machine and spaced apart laterally to either side of an operator''s station closely beside said cutting blades, and third table means extendable outwardly beyond one end of said machine and rearwardly of said second table means.
Claim 10
Dependent Claim
85 words
A slitting machine as defined in claim 4 characterized in that said wheel means includes a pair of wheels carried on lever means pivotally connected to said main frame along a pivot axis parallel to but offset from the axis of said wheels, and the other end of said lever means being manually responsive to pressure applied by an operator to shift said pair of wheels from the retracted to the extended position thereof for rolling movement of said slitting machine to a different location.
Claim 11
Dependent Claim
28 words
A slitting machine as defined in claim 8 characterized in the provision of manually controlled means for releasably locking said pair of wheels in their extended machine-supported position.
Claim 12
Dependent Claim
40 words
A slitting machine as defined in claim 8 characterized in the provision of self-leveling foot engaging means on said lever means operable to remain generally level as said lever means is pivoted by foot pressure between its extreme operating positions.
Claim 13
Dependent Claim
63 words
A slitting machine as defined in claim 10 characterized in that said self-leveling foot engaging means includes means pivotally connecting the same crosswise of said lever means along an axis offset to one side of the center of gravity of said foot engaging means and including means for holding said foot means normally in a convenient position for engagement by the operator''s foot.
Claim 14
Dependent Claim
34 words
A slitting machine as defined in claim 4 characterized in that said motor means is supported on said rigid frame beneath said horizontal lath supporting means and adjacent the axis of said wheel means.
Claim 15
Dependent Claim
25 words
A slitting machine as defined in claim 4 characterized in that said metal cutter blades are located inwardly from the front edge of said machine.
