Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
172 words
A circular saw which comprises: a. a flat metallic saw plate of circular configuration; b. a plurality of flat segment members attached to each face of the saw plate around the entire periphery thereof, each segment member having a plurality of generally buttress-shaped tooth retaining portions located on the outer periphery thereof and extending beyond the periphery of the saw plate, said segment members being in an abutting end-to-end relationship, the segment members on opposite sides of the plate being in a staggered configuration so that the abutting end portions of the members on one side are generally located opposite the central portions of the segment members on the opposite side in a manner in which the tooth retaining portions on each side remain in aligned opposing relationship; c. segment member attachment means to attach the segment members to the saw plate; d. tooth means adapted to fit between the opposed buttress-shaped tooth retaining portions of the segment members; and e. tooth retaining means to lock the sawteeth between the segment members.
Claim 2
Dependent Claim
172 words
A circular saw which comprises: a. a flat metallic saw plate of circular configuration; b. a plurality of flat segment members attached to each face of the saw plate around the entire periphery thereof, each segment member having a plurality of generally buttress-shaped tooth retaining portions located on the outer periphery thereof and extending beyond the periphery of the saw plate, said segment members being in an abutting end-to-end relationship, the segment members on opposite sides of the plate being in a staggered configuration so that the abutting end portions of the members on one side are generally located opposite the central portions of the segment members on the opposite side in a manner in which the tooth retaining portions on each side remain in aligned opposing relationship; c. segment member attachment means to attach the segment members to the saw plate; d. tooth means adapted to fit between the opposed buttress-shaped tooth retaining portions of the segment members; and e. tooth retaining means to lock the sawteeth between the segment members.
Claim 3
Dependent Claim
23 words
The saw of claim 1 in which the end portions of each segment member is truncated along a radius of the saw plate.
Claim 4
Dependent Claim
56 words
The saw of claim 1 in which the segment member attachment means include apertures formed through the saw plate at equiangular positions around a circle lying within and concentric with the periphery of the plate, the number of apertures being at least equal to the number of segment members attached to one face of the plate.
Claim 5
Dependent Claim
29 words
The saw of claim 3 in which the number of apertures within the saw plate is twice the number of segment members attached to one face of the plate.
Claim 6
Dependent Claim
28 words
The saw of claim 4 in which each segment member has two shouldered attachment apertures corresponding in location to the positions of the apertures within the saw plate.
Claim 7
Dependent Claim
50 words
The saw of claim 3 in which the segment attachment means includes a threaded metallic bushing inserted within each attachment aperture in the saw plate and further includes bolts threaded into the bushings from both sides of the assembly so as to lock the opposing segment members to the bushings.
Claim 8
Dependent Claim
21 words
The saw of claim 6 in which the bushings are of softer metal than the corresponding area of the saw plate.
Claim 9
Dependent Claim
48 words
The saw of claim 1 in which the tooth retaining means includes one shouldered aperture and one threaded aperture located in each buttress-shaped tooth retaining portion of the segment members, said apertures being located around circles lying outside of and concentric with the periphery of the saw plate.
Claim 10
Dependent Claim
29 words
The saw of claim 8 in which each tooth means contains two longitudinally displaced apertures located in positions corresponnding to the shouldered apertures in the buttress-shaped tooth retaining portions.
Claim 11
Dependent Claim
37 words
The saw of claim 9 in which the tooth retaining means further comprises two bolts passing in opposite directions through each tooth, each bolt being threaded into one of the opposed buttress-shaped portions of the segment members.
Claim 12
Dependent Claim
24 words
The saw of claim 10 in which each tooth means abuts snugly against the buttress-shaped retaining portions to minimize shear forces on the bolts.
Claim 13
Dependent Claim
22 words
The saw of claim 1 in which the combined segment members, tooth means and tooth retaining means form a structurally integral hoop.
Claim 14
Dependent Claim
18 words
The saw of claim 12 in which the opposing segment members are interconnected by the tooth retaining means.
