Abstract
Abstract A rotary fork for roasting wieners, marshmallows and the like including a cylindrical barrel adapted to rest upon a suitable support, tubes at the front of the barrel telescopably housing tines, cables connected to the tubes, a gearing system at the rear of the barrel coupled to the cables, and a handle element to operate the gearing system to twist the cables and thereby rotate the tubes without rotating the barrel and without affecting the telescopability of the tines.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
141 words
A rotary roasting fork comprising: an elongated barrel; a front mount carried at the forward extremity of said barrel; a plurality of tubes projecting from and rotatably carried by said front mount; a plurality of tines axially telescopably disposed within and projecting from said plurality of tubes, respectively; a plurality of cables coupled to said tubes and extending rearwardly within said barrel; a rear mount carried at the rearward extremity of said barrel and including openings receiving the rearward extremities of said cables; a handle element rotatable upon the rearward extremity of said barrel; and coupling means on said rearward extremities of said cables and on said haNdle element cooperative to rotate said cables upon rotation of said handle element, and means between said tines and tubes whereby said tines are rotatable and whereby said tines are retractable at all times.
Claim 2
Dependent Claim
141 words
A rotary roasting fork comprising: an elongated barrel; a front mount carried at the forward extremity of said barrel; a plurality of tubes projecting from and rotatably carried by said front mount; a plurality of tines axially telescopably disposed within and projecting from said plurality of tubes, respectively; a plurality of cables coupled to said tubes and extending rearwardly within said barrel; a rear mount carried at the rearward extremity of said barrel and including openings receiving the rearward extremities of said cables; a handle element rotatable upon the rearward extremity of said barrel; and coupling means on said rearward extremities of said cables and on said haNdle element cooperative to rotate said cables upon rotation of said handle element, and means between said tines and tubes whereby said tines are rotatable and whereby said tines are retractable at all times.
Claim 3
Dependent Claim
40 words
A rotary roasting fork according to claim 1 wherein resilient means are disposed between said tines and the inner walls of said tubes to develop slight frictional constraint therebetween tending to prevent said tines from moving loosely within said tubes.
Claim 4
Dependent Claim
41 words
A rotary roasting fork according to claim 1 wherein said coupling means comprise an annular gear element carried by said handle element, and a plurality of gears mounted to said rearward extremities of said cables and meshed with said gear element.
Claim 5
Dependent Claim
42 words
A rotary roasting fork according to claim 1 wherein said plurality of tubes are arranged with their longitudinal axes extending outwardly in divergent relation to the longitudinal axis of said barrel whereby the outer extremities of said tines are generously spaced apart.
