Abstract
A dust shroud for gas powered circular saws allows for mounting to a circular saw and for use therewith out hindering the use of the saw. The shroud does not interfere with the ability to operate the saw or set the saw on the ground, and effectively collects dust and debris without reducing the depth of cut.
Claims18
A dust shroud for a gas powered circular saw comprising:
- a dust collection chamber configured to receive the blade of a gas powered circular saw through a slot formed therein such that the dust collection chamber extends around both sides of the saw blade;
- a dust collection passage disposed in fluid communication with the chamber and extending away from the chamber so as to extend below the circular saw;
- and
- a vacuum port disposed in fluid communication with the passage such that a vacuum disposed in the vacuum port can extract dust from the dust collection chamber;
- and
- wherein the dust collection passage comprises a first section which is connected to the dust collection chamber and which extends rearwardly from the dust collection chamber beneath the circular saw, a second section which is connected to the first section and which curves so as to extend laterally from the side of the saw, and wherein the vacuum port is connected to the second section at an angle such that the vacuum port faces rearwardly relative to the saw and is laterally offset relative to the dust collection chamber.

A dust shroud for a gas powered circular saw, the dust shroud comprising:
- a generally enclosed dust collection chamber, the dust collection chamber having a continuous slot formed through a front surface and a top surface thereof and an opening which is wider than the slot formed in a lower surface thereof, the opening being continuous with the slot, the dust collection chamber receiving a circular saw blade through the opening and slot formed therethrough so as to generally enclose an edge and sides of a portion of the blade and such that the edge passes through said opening;
- a dust collection passage pneumatically connected to the dust collection chamber and extending rearwardly therefrom beneath the saw, the dust collection passage having a reduced vertical height and an extended horizontal width, the dust collection passage curving laterally so as to extend towards the side of the circular saw;
- and
- a vacuum port pneumatically connected to the dust collection passage and connectable to a vacuum hose so as to draw air from the dust collection chamber, through the air passage, and through the vacuum port.

A dust shroud for a circular saw comprising:
- a circular saw, the saw comprising:
- a circular blade;
- the dust shroud comprising:
- a generally enclosed dust collection chamber, the dust collection chamber having an opening formed in the bottom thereof and a slot formed through the front and top thereof, the slot being connected to the opening, the slot and opening receiving the blade so as to enclose a portion of an edge and sides of the blade;
- an dust collection passage disposed in pneumatic communication with the dust collection chamber, the passage extending rearwardly from the dust collection chamber underneath the saw and curving laterally so as to extend to the side of the saw;
- and
- a vacuum port disposed in pneumatic communication with the air passage, the vacuum port being displaced laterally from the dust collection chamber and extending rearwardly along the side of the saw.
