Abstract
A hat stretching device including a spaced apart pair of oppositely facing hat engaging arcuate bands which are interconnected by an adjustment block. One of the arcuate bands and the adjustment block cooperatively define a ratchet mechanism which allows the spacing between the hat engaging bands to be quickly, easily, and repeatable set to a coarsely adjusted size. The other arcuate band and the adjustment block cooperatively define a threaded adjustment mechanism which allows the spacing between the hat engaging bands to be finely adjusted to a precise hat engaging size.
Claims10
A hat stretching device comprising:
- (a) first and second band means for placement in a hat to be stretched, said band means being in spaced relationship with each other;
- (b) a threaded rod extending from said first band means toward said second band means;
- (c) a ratchet bar extending from said second band means toward said first band means and in axial alignment with said threaded rod, said ratchet bar having at least a spaced apart pair of ratchet grooves formed therein;
- (d) adjustment block means having a threaded bore on one end in which said threaded rod is mounted and having a smooth bore in its opposite end in which said ratchet bar is axially movable;
- (e) pawl means on the opposite end of said adjustment block means and having a ratchet bar engaging position wherein said ratchet bar is movable in an axially extending direction relative to said adjustment block means to move a selected one of the ratchet grooves of said ratchet bar into latched engagement with said pawl means, said pawl means being movable into a ratchet bar disengaging position;
- and
- (f) release means associated with said pawl means for manually moving said pawl means between its ratchet bar engaging and disengaging positions.
