Abstract
Abstract A miter assembly adapted to produce miter cuts with a power saw, such as a rotary handsaw, and comprising a table having collapsible legs, an elongated base secured onto the table, an aperture through each of the two opposite lateral sides of the base and defining a transverse channel through the latter, a frame pivoted onto the base about an upright axis through the channel, spaced-apart strips to support a saw in projection into the channel and to perform all the angular and inclined miter cuts into the same channel, a locking device to lock the frame for a selected angular miter cut, and a self-adjustable and yieldable clamping device to clamp a piece of work on either side of the elongated base and the underside of the frame.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
218 words
A miter table assembly for a portable power-operated saw comprising a table top, an elongated base secured over said table top and having a channel extending transversely through said base and also opening upwardly thereof, a frame supported on top of said elongated base and pivotable relative thereto about an upright pivot axis, said frame including a pair of spaced-apart supports and a pair of spaced-apart strips attached to said supports, said supports and strips defining a straight slot therebetween registering with said channel, a pair of U-shaped connecting members rigidly interconnecting the ends of said supports and straddling said slot, said U-shaped members resting at their lower ends on said table top in sliding contact therewith, said supports extending laterally from opposite sides of said elongated base, said strips arranged to support And guide a portable power saw with the blade of said saw projecting through said slot and through said transverse channel for operative lengthwise displacement of the saw from one end to the other of said supports and transversely to the channel of said elongated base, said supports each including an arc-shaped portion concentric with said pivot axis, and rotation guiding devices mounted onto said base in juxtaposed position to said arc-shaped portions for guiding said frame for bodily rotation thereof about said pivot axis.
Claim 2
Dependent Claim
218 words
A miter table assembly for a portable power-operated saw comprising a table top, an elongated base secured over said table top and having a channel extending transversely through said base and also opening upwardly thereof, a frame supported on top of said elongated base and pivotable relative thereto about an upright pivot axis, said frame including a pair of spaced-apart supports and a pair of spaced-apart strips attached to said supports, said supports and strips defining a straight slot therebetween registering with said channel, a pair of U-shaped connecting members rigidly interconnecting the ends of said supports and straddling said slot, said U-shaped members resting at their lower ends on said table top in sliding contact therewith, said supports extending laterally from opposite sides of said elongated base, said strips arranged to support And guide a portable power saw with the blade of said saw projecting through said slot and through said transverse channel for operative lengthwise displacement of the saw from one end to the other of said supports and transversely to the channel of said elongated base, said supports each including an arc-shaped portion concentric with said pivot axis, and rotation guiding devices mounted onto said base in juxtaposed position to said arc-shaped portions for guiding said frame for bodily rotation thereof about said pivot axis.
Claim 3
Dependent Claim
25 words
A miter table assembly as defined in claim 1, wherein each of said rotation guiding devices includes a lateral flange engaging the corresponding arc-shaped portion.
Claim 4
Dependent Claim
88 words
A miter table assembly as defined in claim 2, wherein each of said interconnected spaced-apart supports constitutes a substantially semi-annular plate, the inner arc-shaped edge of which forms one of said arc-shaped portions and said rotation guiding devices constitute sector-shaped plates concentrically secured onto said base on opposite sides respectively of said transverse channel and radially inwardly relative to said semi-annular plates and each having the outer arcuated edge thereof forming said lateral flange and arranged to engage over said inner arc-shaped edge of the corresponding semi-annular plate.
Claim 5
Dependent Claim
49 words
A miter table assembly as defined in claim 3, further including a work clamping means including clamping members, a toggle linkage, and a spring means interconnected between said clamping members and said toggle linkage and arranged to allow yieldable engagement of said clamping members with said piece of work.
Claim 6
Dependent Claim
67 words
A miter table assembly as defined in claim 4, further including a locking means constructed and arranged to releasably hold said frame at a selected angle relative to said elongated base, one of semi-annular plates including notches into the outer circumferential edge thereof and said locking means including a spring-biased wedge constructed and arranged to selectively engage into anyone of said notches whereby to hold said frame.
Claim 7
Dependent Claim
99 words
A miter table assembly as defined in claim 4, wherein said clamping members constitute a pair of clamping levers pivoted about a transverse axis and arranged to engage against the underside of said piece of work on opposite sides of said elongated base respectively, said toggle linkage includes a manual lever pivoted to said base about a transverse axis thereof, a push-pull link connected at one end to said manual linkage and at the other end to said spring means, and the latter is connected to said clamping levers and arranged to cause said yieldable engagement of the latter.
