ARTHUR CARSON, OF MELBOURNE, VICTORIA, AUSTRALIA, ASSIGNOR OF ONE-HALF TO JOHN Sl-IAW GREEK, OF MELBOURNE, VICTORIA,
SAFETY HiJlJSE-Zi -lULD LAMP.
SPECIFICATION forming part of Letters Patent No. 729,52, dated June 2. 1903. l Application filed June 12, 1902. Serial No. 111,382. (No model.)
To all whom, it may concern:
Be it known that I, ARTHUR CARSON, a subject of the King of Great Britain, residing at No. 454 Collins street, Melbourne, in the State of Victoria, Australia, have invented new and useful Improvements in Safety Household- Lamps, of which the following is a specilication.
The object of this invention is to provide a lamp for household use in which the light will be extinguished on the lamp being overturned, so obviating the present danger in the use of kerosene-lamps. a simple means for extinguishing the light at any time desired. Further, the lamp is constructed so that the light will be extinguished it dropped by a person carrying the lamp.
. In order that the invention may be clear,
I will now describe same with reference to the by e nut 14:. The rod 6 guide 15, and this dish or guide isconnected accompanying sheet of drawings, in which- Figure 1 represents a vertical section taken through a lamp provided with the improvements. Fig. 2 shows an outside view of n1ovable sleeve and its connections. Fig. 3 shows the movable parts in their altered position in relation to the fixed parts.
The invention is illustrated as applied to one form of lamp havinga circular wick; but it willbe understood that the lamp might be made of various designs with straight wick, single ,or double.
1 represents the lamp-reservoir, on which is mounted the wick-carrier or burner 2, that has the channel 3 for the passage of the Wick and the opening 4 for the air-inlet. Within the burner is set a cylinder 5, that is mounted on a rod 6. The cylinder 5 is perforated with holes for the admission of air. A conical sleeve 7 encircles the burner 2, and this is con'nected to the cylinder 5 by means of a screw 8, which passes through plate 9, attached to the saidsleeve. The rod 6 pro ceeds through a tube 10', that is passed throng the reservoir of the lamp and which screws at its base into the frame 11 of the lamp at the base of the reservoir The frame 11 is mounted on tube 12, that is supported by base 130i the lamp. In the drawings the tube is illustrated as being held in position rests upon a dislzz or The invention also provides.
by a link 16 tonne arm-of a lever 17 and is centered on pivot-bearing in the tube 12. The other arnrof the lever 17 is connectedby a link 19 with aweight 20, which normally-rests upon the table supporting the lamp.
Means are provided for holding the rod 6 when the lamp is to be lifted and the light kept banning and which consists of an arm or'lever 2i, articulated to the frame 11 and arranged to bear upon afpin 22, that passes through the frame 11 and tube 10 and butts against the rod 6.
23 represents the lampwick, that is moved in the ordinary way. 1
25 representsthe ordinary support for the lamp-chimney, and 26 an outer casing supported on the base and which serves a par:
pose in the shown. 7 When the invention is applied to a lamp with a flat wick or wicks, the cylinder 5 will be dispensed with and the sleeve 7 will be of a shape to correspond with and fit upon the burner, and said burner will be secured directly to the rod 6.
The modus operandi of the invention is asfoliows: When in ordinary use with the light burning, the parts will be in the relative positions shown in Fig. 1, with the weight 20 particular design oflamp here resting on the table, and the rod 6, with the cylinder 5 and sleeve 7, in the down position. Should the lamp be overturned, the weight 20 will fall and operate the lever 17 to raise the disk 15, and so force up the rod 6 and with it the cylinder 5 and connected sleeve 7, so causing the instant extinction of the light, theparls being now in the relative position shown, Fig. 3. from the table the same effect will be obtained and the light extinguished, if so desired; but
if it is desired to more the lamp without one tingui'shing the light the lever 21 maybe pressed with the thumb in the act of, lifting the lamp, which. will cause thepiu 21 to act on the rod 6to hold the parts in the positions shown on Fig. 1. Should the lamp be dropped accidentally;\the pressure being released from the lever 21 the parts will immediately set to extinguish the light. I
' Having now particularly describedand ascertained the nature of my said invention and By'lifting the lamp in what manner the same is to be perfdrmed,
i declare that what I claim is- 1'. In .a household-lamp, in combination a eentral tube 6 passing through lamp-reservoir and an enlarged tube 12 at the base of same, a rod;- fiipassingthrough the tube 10 and carrying a cylinder 5 within the burner and a sleeve 7 connected therewith outside the burner, a
disk 15 within the tube 12supporting the rod '6, a lever 17 on pivot within the tube and connected on the one side to the disk 15 and the other side to weight 20 and means for holdingthe rod 6 substantially as and for the purposes described.
- 2. In a household-lamp, in combination a central tube G'passing through lamp-reservoir and entering frame 11, an enlarged tube 12, supporting-frame 11- a rod 6 passing through teases the tube 10 and carrying a'ey1inder-5 within the burner and a sleeve 7 having opening 4 and connected with cylinder 5 by cross-bar 9 and pin 8, aldisk 15 within the tube 12 supporting the rod 6, a lever 17 onpivot within the tube and connected on the one side to the disk 15 and the other side to weight 20, a pin 22 passing through frame 11 and tube 10 and a pivoted lever bearing upon said pin substantially as and for the purposes described.
