AGNES S. L. SINCLAIR, OF SAN ANTONIO, TEXAS.

WIND AND BUG SHIELD FOR LAMP-CHIMNEYS.

Specification of Letters Patent.

Patented Nov. 19, 1918.

Application filed October 3, 1917. Serial no. 194.552.

To all 10/2077? it may concern.-

Be it known that I, AGNES S. L. SINCLAIR, a citizen of United States, residing at San Antonio, in the county of Bexar, State of Texas, have invented certain new and useful Improvements in Wind and Bug Shields for Lamp-Chimneys; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a new wind shield for oil burning lamps, and has for an object to provide a shield of this character which may be conveniently applied to the chimney of a lamp and will effectively serve to prevent a current of air from extinguishing the lamp as now frequently occurs.

A further object of the present invention is to provide a lamp shield which is of an exceedingly simple construction and may be manufactured and marketed at a relatively low cost.

With the above and other objects of similar nature in view, the invention consists in the construction, combination and arrangement of parts, set forth in and falling within the scope of the appended claims.

In the drawing Figure 1 is a side elevation of a portion of a lamp and chimney with the invention associated therewith,

Fig. 2 is a vertical section therethrough,

Fig. 3 is a top plan view, and

Fig. 4 is a perspective view of the device removed.

Referring now more particularly to the accompanying drawing, there is shown a portion of a kerosene lamp of conventional type including the burner 5 and the chimney 6.

My improved shield consists of a hollow cylindrical member .7 preferably formed from a blank of sheet metal that is suitably rolled and connected along its meeting edges. Said cylindrical member 7 for a portion of its area is provided with a plurality of perforations 6 while its remaining portion 9 is imperforate as shown. For the upper end 'of the cylinder 7 there is provided a closure cap 10 the same having a downturned circumseribing flange 11 adapted to snugly receive said cylinder end.

The cap 10 is also provided for a portion of its area with perforations 12 while the remaining portion 13 is imperforate, said per forate and said imperforate portions respectively forming continuat-ions of the perforate and imperforate portions of the cylinder 7.

In use the device is applied to the lamp in the manner illustrated in Figs. 1 and 2, the cylindrical member 7 being placed removably over the chimney 6. The member 7 with its cap is positioned upon the chimney as shown in Figs. 1 and 2 where it will be noted that there is a space between the wall of the member 7 and the outer surface of the chimney. The lamp is turned so that the imperforate side of the guard is in the direction of the wind and if any currents of air tend to pass downwardly through the cap, the pull of the wind in its passage across the perforations will serve to relieve the increased internal pressure occasioned and the downward draft would therefore be inwardly through the uppermost perforations and then downwardly and out through the side perforations.

It will of course be understood that while the top member is referred to as a cap, this does not mean that it is removable, the drawing in this regard serving to illustrate one of many ways in which the article may be specifically constructed. In order that the attachment may be fitted to dimensions of various diameter, longitudinal slots 14: are formed extending from the lower edge to near the top and permit of expansion of the lower end of the cylindrical member.

What I claim is:

1. A windshield for lamps, comprising a hollow cylinder closed at its upper end and open at the lower end and having numerous perforations on one side throughout its length, its opposite side being imperforate; said windshield being adapted to be placed on and over the top of a lamp chimney with the imperforate part thereof kept to the windward side of the chimney.

2. A windshield for lamps, comprising a hollow cylinder closed at its upper end and open at the lower end and adapted to be placed on and over the top of a lamp chimney; one side of said cylinder having numerous perforations throughout its length and the opposite side thereof being imperforate; and the half of the closed top adjacent the perforated side of the cylinder being also numerously perforated.

3. A windshield for lamps, comprising a hollow cylinder closed at one end and open at the other end, the open end of the cylinder having radial slots to permit it to be thereof at the side against which the Wind fitted onto different chimneys, one side of is blowing.

said cylinder being numerously perforated In testimony whereof, I afiix my signature and the ogposite aside the}??? bainfig inilperi in the presence of two Witnesses.

forate, an the a jacent a 0 t e c ose top of such cylinder being also numerously AGNES SINCLAIR perforated; said attachment being adapted Witnesses:
