Abstract
Abstract A snow broom including a handle carrying a transversely extending base member to which are affixed a plurality of overlapping flexible metal tines. The stiffness of the tines can be adjusted by means of a sliding restraining member which restricts the freedom of flexure of the tines, and which when fully extended converts the broom into a shovel.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
108 words
A snow broom assembly comprising: a. a handle; b. a base member carried at one end of the handle; c. a plurality of closely spaced overlapping parallel resiliently flexible tines extending outwardly from the base member; and d. means for selectively permitting the tines to flex individually in a rake-type action or cause the tines to be maintained in a blade-like array in a shovel-like action, said means being defined by a restraining member carried by the base member and positionable to surround the tines near the base member, said restraining member being movable to the free end of the tines maintain said tines in said blade-like array.
Claim 2
Dependent Claim
108 words
A snow broom assembly comprising: a. a handle; b. a base member carried at one end of the handle; c. a plurality of closely spaced overlapping parallel resiliently flexible tines extending outwardly from the base member; and d. means for selectively permitting the tines to flex individually in a rake-type action or cause the tines to be maintained in a blade-like array in a shovel-like action, said means being defined by a restraining member carried by the base member and positionable to surround the tines near the base member, said restraining member being movable to the free end of the tines maintain said tines in said blade-like array.
Claim 3
Dependent Claim
115 words
A snow broom assembly comprising: a. a handle; b. a base member carried at one end of the handle; c. a plurality of closely spaced overlapping parallel resiliently flexible tines ''''Z'''' shaped in transverse cross section extending outwardly from the base member; and d. means for selectively permitting the tines to flex individually in a rake-type action or cause the tines to be maintained in a blade-like array in a shovel-like action, said means being defined by a restraining member carried by the base member and positionable to surround the tines near the base member, said restraining member being movable to the free end of the tines to maintain said tines in said blade-like array.
Claim 4
Dependent Claim
115 words
A snow broom assembly comprising: a. a handle; b. a base member carried at one end of the handle; c. a plurality of closely spaced overlapping parallel resiliently flexible tines ''''Z'''' shaped in transverse cross section extending outwardly from the base member; and d. means for selectively permitting the tines to flex individually in a rake-type action or cause the tines to be maintained in a blade-like array in a shovel-like action, said means being defined by a restraining member carried by the base member and positionable to surround the tines near the base member, said restraining member being movable to the free end of the tines to maintain said tines in said blade-like array.
Claim 5
Dependent Claim
123 words
A snow broom assembly comprising: a. a handle; b. a base member carried at one end of the handle; c. a plurality of closely spaced overlapping parallel resiliently flexible tines extending outwardly from the base member; d. means for selectively permitting the tines to flex individually in a rAke-type action or cause the tines to be maintained in a blade-like array in a shovel-like action, said means being defined by a restraining member carried by the base member and positionable to surround the tines near the base member, said restraining member being movable to the free end of the tines to maintain said tines in said blade-like array; and e. means carried by said handle for moving said restraining member to said positions.
Claim 6
Dependent Claim
