WILLIAM E. MASON, OF CHICAGO, ILLINOIS, AND JOHN F. MASON AND EDWARD H. MASON7 or DES MOINES, IOWA.

lMPRovEMENT. `IN LANTERNS.

Specification forming part of Letters Patent N o. 222,145, dated December 2, 1879; application filed November 23, 1878.

To all whom 'it may concern:

Be it known that We, WILLIAM E. MASON, of Ohicago,`Illinois, and JOHN F. MASON and EDWARD R. MASON, of Des Moines, Iowa, have invented an Improved Lantern, of which the following is a specification.

The object of our invention is to prevent lamps and lanterns from being ai'ected by the pressure of the outside air and wind which frequently interrupt combustion, cause smoke, ickering, extinguishment, and accident.

1t consists in forming, arranging, andcombining breaks or detlectors in the air-passages and chambers used to conduct air and oxygen to the burners Aand combustionchambers of lamps and lanterns in such a manner that the air will move in a zigzag or serpentine line and in a continuons steady 110W, as hereinafter f'ully set forth.

Our drawing is a longitudinal partial section of a lantern, and-illustrates the construction and operation of our complete invention.

a a represent the cylindrical body of a lantern. Itis made of sheet metal, and may vary in size and conguration as desired. It has a Haring flange, b b, at its lower portion, which forms a broad base, upon which the complete lantern may rest. Perforations in this ilange allow air to pass from the outside to the interior when the lantern rests upon a table or other solid surface. y

cis an oil-chamber, fixed in the inside of the body a a in any suitable way. It may be filled through the induction-port and tube d that extends above the top plate of the body a a.

e is the neck of the oil-chamber and vessel c, that supports the burner and incloses the wick that extends from the burner to the oil.

fis a, burner, which may vary in form. g is a perforated diaphragm surrounding the burner. h is the top plate of the body a a. It has a neck, t' t', corresponding with the neck e of the oilchamber, which neck e it incluses in such a manner as to produce an annular airchamber'and conduit leading from below the top plate, h, to the top of the burner and the burning wick 7c. i y

l t are circular rims xed to the under side of theixed plate 7L, and represent a graduated series of wind breaks or deflectors in a vertical i position, to affect the air moving at right an gles thereto.

mm are correspondin g rims xed on top of the oilchamber, to extend upward between the depending rims `l Z in such a manner that each one of the deectors Zand m will act as a break in regulating the How of air that must produce perfect combustion, and a good, safe,

and steady lightis the advantageous result.

n n is an annular chamber surrounding the oil-reservoir c. It has a series of perforations, l 2 3 4, at its lower end, through which air is admitted to be conducted upward toward the burner.

r r represent a series of delectors corresponding with the deectors m and l, xed in a horizontalposition against the inside of the body a. a. s s are corresponding,` deilectors, fixed against the outside of the oil-chamber c. These horizontal breaks r s in the vertical annular conduit n n may be used independently to accomplish, in some degree, the results contemplated by combining them with the vertical breaks m l in the horizontal conduit formed over the top of the oil-chamber c, to thereblsr lengthen the serpentine passage-way that conducts air from Vthe outside of the lantern to the burner, to produce perfect combustion and a safe and steady light by preventing an irregular pressure of the continuous air-current required to feed the flame at the top of the wick 7c, and to keep every portion of the metal below the burner cool.

is an auxiliary vertical tubular conduit passing through the oil-chamber c, to connect with the air-passage surrounding the burner. It-,has breaks y and z, corresponding with the breaks o" and s in the annular conduitn n, and one or more of these tubes as may be used .in

'lieu of the annular conduit, or in combination therewith, to supply the amount of air re quired, and to suit the different forms, sizes, and capacities of the lamps and lanterns that may be made by adapting our invention to all the practical purposes for which lamps and lanterns are require Any suitable and artistic formof lamp or lantern may be thus provided with one or more conduits, that will convey air in a continuous serpentine and steady stream from the outside to the burner, to produce an economical, satisfactory, and safe illuminator that can be advantageously used out of doors in a Wind as well as in a house.

. when the continuous-waved plate is used as a deilector in a vertical position, it forms a seriesof pockets into which the air enters and then passes downward and out of thc pockets before it ascends to feed the dame; and when it is used in a horizontal position it is simply an uneven partition'that divides the air-chamber into tWo series ot' radial passage-Ways, to conduct the air through numerous and distinct conduits from the outside toward the burner inthe center.

Our series of independent and xed defiectors do not divide lthe volume of air admitted into the chambers or passage-Ways, but simply deiiect it abruptly at intervals to resist outside pressure, and to cause a continuons steady flow, as required to produce a uniform and steady light.

We claiml. In a lamp or lantern, a horizontal airpassage having a series of independent and fixed wind breaks or detlectors, m and Z, standing in opposite Ways from opposite sides ofthe top and bottom Walls, substantially as shown and described, to produce a zigzag or serpentine motion of the air, as set forth, for the purpose specified.

2. The annular chamber and conduit an, having the air breaks the opposite walls and defiectors fr s fixed to of said chamber, substantially as shown and described, for the purposes specified. f 3. The tubular conduit having the breaks and detlectors y and z, substantially as shown and described, for the purposes specified.

4. The body a a, having the fixed top h, neck t' fi, and Wind-breaks ll, in combination with the oil-reservoir c, having a tube or neck, e, to support a burner and Wind-breaks m m, substantially as shown and described, for the purposes specified.

5. The combination of the body a a., having top h i i, vertical breaks Z l, horizontal breaks r r and perforations l 2 3 4, With the oil-reservoir c, having top e and breaks s s, substantially as and for the purposes set forth 6. The body a a, having a perforated ange,

b b, a top, h i t', perforations l 2 3 4, vertical breaks Z l, and horizontal breaks r t', the oilreservoir c, having a neck, e, vertical breaks m m, and horizontal breaks s s, when arranged and combined in a lamp or lantern, substantially as shown and described, to operate in the manner set forth.

7. The body a a, having a top, h i t', and vertical breaks L l, the oil-reservoir c, having a top, e, vertical breaks m on, and the conduit x, having breaks y and z, when arranged and combined in a lamp or lantern substantially as shown and described, to operate in the manner set forth.

8. The body u. a, having a top, hi i, and breaks l l and r r, and perforations 1 2 3 4, the oil-vessel c, having top c and breaks m m and s s, and the tube x, having breaks y and z, when arranged and combined in an illuminator, substantially as shown and described, to operate in the manner and for the purposes specified.
