Abstract
The present invention pertains to an electric-mechanical portably held and operated pipe cutting tool with hidden non-exposed blades that cut a various range and makeup of cylindrical pipe using a duality of synchronized perpetually designed blade motions within a drum shaped compartment which comprises these same blades mounted on a squirrel cage frame of which moves independently and opposite of the blades while sharing the same source of mechanical power.

- A planetary inside gear or a cylindrical solid chain of which makes direct contact with and drives said spur gears or sprockets attached to stems on the outside of said squirrel cage frame at the same time penetrating said cage, with said planetary inside gear or said cylindrical solid chain consisting of two flanges bolted to both sides of said planetary inside gear or said cylindrical solid chain to hold said planetary inside gear or cylindrical solid chain on top of spur gears or sprockets floating having said spur gears or sprockets as a support means while at the same time driving the same said spur gears, the same said planetary inside gear or said cylindrical solid chain with flanges bolted to its sides also being bolted to the second beveled planetary gear
- A bevel gear of which drives said first beveled planetary gear attached directly to said cage with the same said bevel gear being attached to a stem and passes through the cutting drum wall and is driven by a gear train
- A gear train arranged as two separate gear trains being driven in opposite directions by the same main motor drive pinion
- A second bevel gear attached to a second stem that passes through the same cutting compartment wall on the opposite side of said cage and drives the second said beveled planetary gear that has a planetary inside gear or cylindrical solid chain bolted concentrically to said second beveled planetary gear
- A second planetary inside gear or cylindrical solid chain with flanges bolted to the outer side portions therewith similar to the first aforementioned planetary inside gear or cylindrical solid chain with flanges that work to keep the second planetary inside gear or cylindrical solid chain supported by spur gears mounted on the cross braces that support said blade housing with said spur gears or sprockets being located on the opposite side of the blade housing and close to the center of the outer edge of cage next to the blade housings with the spur gears or sprockets acting to support said second inside gear while at the same time being driven by the same said planetary inside gear or cylindrical solid chain with flanges mounted on the sides thereof while floating on top of spur gears or sprockets attached to the cross braces supporting the blade housings The second planetary inside gear or cylindrical solid chain act to rotate blade housings on an axis towards pipe to be cut
- An arrangement of spur gear a pad attached to a handle, a brake pad and a brake arrangement to adjust said blades toward pipe and to keep blade locked in this position spring biased toward the pipe to be cut
- A motor that drives a primary pinion mounted on the main motor shaft
- An arrangement of curtains that closes around pipe being cut through turning an exterior knob in order to protect user from flying debris.
A pipe cutting tool comprising:
- An outer housing having an opening therein
- An external trigger and an external trigger release button
- An external handle sitting on top of external saw housing a release button on top of said external handle
- An external knob for a jaw assembly with the jaw assembly being adjusted by said external knob both toward and away from pipe being cut
- An arrangement of one or more circular saw blades or an abrasive circular disk each within its own housing inside of opening of said saw body
- A number of blade housings mounted on a squirrel cage frame housing circular saw blades or abrasive circular disk said blade housings being penetrated through their body on the end portion opposite said blades so that the blade end pivots on an axis towards and away from pipe
- A squirrel cage frame having two tiers
- A drum housing casted as a compartment on the inner side of the outer housing
- A planetary bevel gear bolted directly to said cage on one side with the opposite side consisting of
- An arrangement of individual spur gears or sprockets along the peripheral inner axis attached to stems that pass through said cage frame and also passing through
- Spacers arranged to divide said cage from said blade housings while allowing said blade housings to pivot along their own axis
- A second planetary bevel gear on the opposite side of said cage where the first said planetary bevel gear is bolted thereto where said second planetary bevel gear floats on top of said spur gears or sprockets and second planetary bevel gear is also bolted to
- A planetary inside gear or a cylindrical solid chain of which makes direct contact with and drives said spur gears or sprockets attached to stems on the outside of said squirrel cage frame at the same time penetrating said cage, with said planetary inside gear or said cylindrical solid chain consisting of two flanges bolted to both sides of said planetary inside gear or said cylindrical solid chain to hold said planetary inside gear or cylindrical solid chain on top of spur gears floating having said spur gears or sprockets as a support means while at the same time driving the same said spur gears or sprockets, the same said planetary inside gear or said cylindrical solid chain with flanges bolted to its sides also being bolted to the second beveled planetary gear
- A bevel gear of which drives said first beveled planetary gear attached directly to said cage with the same said bevel gear being attached to a stem and passing through the cutting drum wall also driven by a gear train
- A gear train arranged as two separate gear trains being driven in opposite directions by the same main motor drive pinion
- A second bevel gear attached to a second stem that passes through the same cutting compartment wall on the opposite side of said cage and drives the second said beveled planetary gear that has a planetary inside gear or cylindrical solid chain bolted concentrically to said second beveled planetary gear
- A second planetary inside gear or cylindrical solid chain with flanges bolted to the outer side portions therewith similar to the first aforementioned planetary inside gear or cylindrical solid chain with flanges that work to keep the second planetary inside gear or cylindrical solid chain supported by spur gears or sprockets mounted on the stems that support said blade housing with said spur gears being located on the opposite side of the blade housing and close to the center of the outer edge of cage next to said blade housings with said spur gears or sprockets acting to support said second inside gear or cylindrical solid chain while at the same time being driven by the same said planetary inside gear or cylindrical solid chain with flanges mounted on the sides thereof while floating on top of spur gears or sprockets attached to the cross braces supporting the blade housings The second planetary inside gear or cylindrical solid chain act to rotate blade housings on an axis towards pipe to be cut on the outer side of planetary inside gear or cylindrical solid chain opposite the inner teeth with the outer surface being smooth in the embodiment where a brake section is not used or in the alternate embodiment having teeth when using a brake section and having the capability to adjust the latter being the best mode because of the simplicity and lack of an additional gear train

- two wide spur gears between said supports on the outside of said supports you have,
- two spring boxes attached to the stems of said spur gears through said supports, said spring boxes are biased up toward the top of saw to keep said spur gears suspended above fourth planetary inside gear of which in this embodiment not being best mode but the original configuration brought forth, said inside gear in this embodiment also having a sixth planetary gear bolted to the top surface back to back inside teeth and outside teeth therewith.
A pipe cutting tool comprising:
- A process where you have plural blades that are engaged with a motor and rotates through pinions, gears, chains, the rotating blades being mounted on a cage that is rotated in the opposite direction by the same said motor where the blades are in constant motion on two planes inducing faster cutting and less blade wear.
