Claims
- 1. In an orbital saw for cutting paper tubes:
- upright frame means;
- a horizontally extending main slide shaft fixed adjacent the top of said frame means;
- an upright saw blade frame including an upper part and a lower part each constructed of substantially square tubing and said parts being laterally off-set a distance substantially the same as the width of a tube;
- means at the lower end of said saw blade frame for releasably maintaining a cam roller stud;
- a pair of re-circulating bearing means mounted on said slide shaft and secured adjacent the top of said saw blade-frame and providing for the saw blade frame to reciprocate and to swing on the slide shaft;
- guide means comprising a pair of spaced apart rods connected to said saw blade frame and extending parallel one another in a direction transverse the axis of said slide shaft;
- a saw blade motor mounting plate;
- bearing means connecting the saw motor mounting plate to said guide means for reciprocating motion along the guide means;
- a saw blade motor mounted on said plate for movement therewith and a saw blade mounted on the motor to be rotated thereby;
- nut means mounted on said saw blade frame;
- control means including first and second relatively movable elements, the first element being fixedly connected to said saw blade motor mounting plate for causing movement of same and the axis of relative motion between the elements being parallel to said rods and equidistant therefrom;
- an adjusting screw mounted in said nut means for movement back and forth therein and being disposed generally co-axial with said axis of relative motion between the elements, one end of the screw being connected to said second element for moving the same;
- means operative to move said first element to a cutting position wherein it is immovable with respect to the second element whereby motion of the adjusting screw causes said first element and said saw blade mounting plate to move relative to said saw blade frame, the cutting position being for use in setting and maintaining the saw blade in condition for engaging and cutting a tube and said means to move being further operative to move said first element and mounting plate to a non-cut position wherein the first element and mounting plate are immovable with respect to the blade saw frame, the non-cut position being for use in setting and maintaining the saw blade in condition whereby the blade cannot engage and cut a tube.
- 2. In an orbital saw for cutting paper tubes:
- upright frame means;
- a horizontally extending main support plate fixedly connected to said frame means;
- cam means fixedly mounted on the top side of said main support plate, the cam means having circular cam channel for receiving follower means and an elongated straight slot extending thru the cam means and being symmetrical and co-axial with a diameter of the cam channel;
- a slot formed in said main support plate and extending co-extensive with the slot in said cam means;
- a horizontally extending adjustable plate disposed underneath said main support plate and extending across said support plate slot;
- a pair of spaced bars fixed to the underside of said main support plate;
- a pair of spaced slide rods connected to said bars and extending generally parallel to said support plate slot and being disposed underneath said adjusting plate;
- bearing means connected between said slide rods and said adjustable plate and providing for linear reciprocating motion of said adjustable plate;
- crank shaft means mounted on said adjustable plate for movement therewith and for rotation about a vertical axis and extending up thru said slots; and
- drive crank means, connected to the top of said shaft for rotation thereby and extending radially from the shaft above and radially beyond said cam means, the drive crank means having a slot extending substantially thruout and the slot being for use in receiving driver means.
- 3. In an orbital saw for cutting paper tubes:
- upright frame means;
- a horizontally extending main support plate fixedly connected to said frame means;
- a horizontally extending adjustable plate disposed underneath said main support plate;
- a pair of spaced bars fixed to the underside of said support plate;
- a pair of spaced slide rods connected to said bars and being disposed underneath said adjustable plate;
- bearing means connected between said slide rods and said adjustable plate and providing for linear reciprocating motion of said adjustable plate;
- an adjusting screw rotatably mounted on said frame means and nut means fixed to said adjustable plate, rotation of the screw causing said reciprocating motion of the adjustable plate;
- a crank shaft housing fixedly connected to the underside of said adjustable plate for movement therewith;
- a crank shaft rotatably mounted in said housing and extending thru said adjustable plate and upwardly thereof;
- a crank shaft gear connected to the bottom of said crank shaft;
- a crank shaft drive gear meshing with said crank shaft gear for driving the same;
- a gear reducer mounted on said adjustable plate for movement therewith and extending downwardly therefrom and connected to said crank shaft drive gear for driving the same, the reducer having an input shaft;
- an assembly means mounted on the underside of said adjustable plate having an outwardly extending control shaft and an outwardly extending output shaft;
- manually operable means to operate said control shaft including an adjusting knob mounted on said frame means, a drive shaft connected between said knob and said control shaft including a pair of universal joints and a spline connection accommodating said linear motion of the adjustable plate; and
- a pair of pulleys, one on said gear reducer input shaft and one on said assembly output shaft and belt means drivingly interconnecting the pulleys.
