Abstract
Abstract A table lamp having a pedestal and globe each with circular cross-sections has 12 vertical slots cut in the upper edge of the pedestal at 30 degree intervals and 3 inwardly projecting lugs on said globe arranged to engage in 3 of said slots with no more than 30 degrees rotation of the globe relative to the pedestal. The stability of the assembly is improved while retaining the simplicity of use of prior devices.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
188 words
A lamp of the type having a flame source and a shield to prevent extinguishing of the source comprising a pedestal having a body portion and a central receptacle portion containing a flame source, a generally horizontal top surface on an upper edge of the body portion of said pedestal, a plurality of radial slots that pass downwardly through said horizontal top surface of said body, each to the same depth, each slot having opposed side walls and a bottom wall contained in said body, shield means mounted on said pedestal having at least three radial inwardly extending lugs mounted on an interior surface of said shield, and each of said lugs having opposed side walls and a bottom wall and being slidably received in a slot so that the bottom wall of the lug rests upon the bottom wall of the receiving slot and the side walls of said lugs extend upwardly beyond the top surface of said body whereby at least two of said lugs are gripped by the side walls of their respective receiving slot when said shield means is moved laterally on said pedestal.
Claim 2
Dependent Claim
188 words
A lamp of the type having a flame source and a shield to prevent extinguishing of the source comprising a pedestal having a body portion and a central receptacle portion containing a flame source, a generally horizontal top surface on an upper edge of the body portion of said pedestal, a plurality of radial slots that pass downwardly through said horizontal top surface of said body, each to the same depth, each slot having opposed side walls and a bottom wall contained in said body, shield means mounted on said pedestal having at least three radial inwardly extending lugs mounted on an interior surface of said shield, and each of said lugs having opposed side walls and a bottom wall and being slidably received in a slot so that the bottom wall of the lug rests upon the bottom wall of the receiving slot and the side walls of said lugs extend upwardly beyond the top surface of said body whereby at least two of said lugs are gripped by the side walls of their respective receiving slot when said shield means is moved laterally on said pedestal.
Claim 3
Dependent Claim
45 words
A device as described in claim 1 wherein said plurality of slots are a multiple of the number of lugs on said shield means, extend radially entirely through the upper edge of the body portion and are at least as deep as they are wide.
Claim 4
Dependent Claim
29 words
A device as described in claim 2 further defined by said plurality of slots being arranged at uniform intervals about the top of the body portion of said pedestal.
Claim 5
Dependent Claim
66 words
A device as described in claim 1 wherein said shield means comprises a globe of light transmitting material, said slots number at least as many as there are lugs on said globe and said slots are at least as deep as said lugs are wide to capture said lugs in the radial slots in said body top surface when said globe is seated on said pedestal.
Claim 6
Dependent Claim
47 words
The invention of claim 1 wherein said lugs are dimensioned to fit said slots in smooth, slidable engagement, as said shield means is operatively installed on said pedestal to prevent rotational and lateral movement of said shield means when said shield means is seated upon said pedestal.
Claim 7
Dependent Claim
65 words
The invention of claim 1 wherein said shield means comprises a globe having at least three inwardly extending lugs and said pedestal has twelve equally spaced vertical slots cut in the body top support surface so that the globe may be seated on said body top support surface and the lugs engaged in said slots by no more than thirty degrees rotation of said globe.
Claim 8
Dependent Claim
34 words
The invention of claim 6 wherein said lugs are positioned on said globe so as to hold the globe away from the upper lip of said pedestal to provide ventilation for said flame source.
Claim 9
Dependent Claim
57 words
The invention of claim 1 further characterized by said pedestal being of circular cross section, said flame source being a liquid fuel disposable fuel cell and burner, and said shield means being a glass globe having at least three lugs, and said pedestal having twelve (12) slots cut therein to selectively receive the lugs of said globe.
Claim 10
Dependent Claim
56 words
The invention of claim 1 further characterized by said pedestal being of circular cross section, said flame source being a liquid fuel refillable fuel cell and burner, said shield means being a glass globe having at least three lugs, and said pedestal having twelve (12) slots, cut therein to selectively receive the lugs of said globe.
Claim 11
Dependent Claim
50 words
The invention of claim 1 further characterized by said pedestal being of circular cross section, said flame source being a candle, said shield means being a glass globe having at least three lugs, and said pedestal having twelve (12) slots cut therein to selectively receive the lugs of said globe.
