AUTOMATIC CANDLE EXTINGUISHER. APPLICATION FILED FEB. 1, 191a.

Patented July 1, 1919.

- mutt/woo James abliowou o APH CD., WkSHlNOTUN D C Tooll whom it may ooncern; I u Be it known that 1,; JAMES BAIRD, a subject of the King of Great Britain, residing at Ardmore, Papakura, New Zealand, have invented certainwnew" and usefulImprovements in Automatic Candle-Extinguishers i and I do declare the following to bea full, clear, and GXELObdGSCI'lPtlOIll of the invention,

snchfas will enable othersa skilled in the art to which it appertains to make and use the" provide an extremely "simple in'exp enfsive, yet a highly efiicient support fonthe a extinguishing cap.

A further object is to provide novel means for limiting the amount which the prong to be described, is permitted to penetrate the candle, whereby possible breakage of the latter is prevented.

A still further object is to provide an improved type of lever upon which the ex tinguishing cap is carried.

With the foregoing general objects in view, the invention resides in the novel features of construction and unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which form a part of this specification and in which Figure 1 is a side elevation of the improved extinguisher applied to a candle;

Fig. 2 is an enlarged vertical section of the device in operative position;

Figs. 3 and 4 are respectively horizontal and vertical sections on the planes indicated by the lines 3-3 and 44 respectively of Fig. 1; and

Fig. 5 is a plan view of the sheet metal blank from which the support is constructed.

In the drawings above briefly described, the numeral 1 designates a support formed of a single T-shaped sheet metal blank as illustrated in Fig. 5, the shank 2 of said blank being bent substantially upon itself along its longitudinal center to form a channel shaped standardi3, the two halves 40f the head of the T extending in parallel re lation from the lower ends of the side flanges 5 of said standard, to form a pair of candle gripping arms. These arms are bulged outsurname cnnnnn-nxrmenrsnnn.

, wardly: between theirvends {LS3 indicated at ing, a closed r1001)? 10 and an a open loop" i A suitable pivot pin" 12 passes, through the a closed loop 10 anduthrongh theside flanges 5 of the standard 3-towpivotally mount the lever 8, whereas a pin 13 extends longltudiinner end received snugly in the open loop 11, said pin being soldered or otherwise secured in place. The outer end of the pin 13 extends beyond the lower end of the lever 8 and is sharpened as shown at 14 to provide a prong adapted to penetrate the candle to hold the lever so as to retain the extinguishing cap 9 in inoperative position until the candle has melted sufficiently to release the prong. When this occurs, however, the cap automatically drops to the position of Fig. 2 and thus extinguishes the flame.

In order to prevent forcing of the pin 13 into the candle to an extent which might break the latter, it becomes highly expedient to provide a suitable stop, and although this stop could be embodied in a number of forms, I prefer to bend the lower end 15 of the lever 8 outwardly a slight distance from the pin 13 so that said end of the lever constitutes a stop for the purpose specified. Furthermore, since the lever is of greater width than the pin 13, it will serve to a large extent to prevent melted wax from accumulating beneath the pin, so that the of said standard, a pivot pin passing preferto bend the lower edges of thearms 4 upwardly to provide reinforcing flanges 16, therefor, said flanges contacting with'the outer side of said arms as shown clearly in Figs. 1, 3 and 4. v

I claim 1. A. candle extinguisher comprising a support formed of a T-shaped sheet metal blank bent substantially upon itself along the center of its shank to form a channel shaped standard, the two halves of the head of the T extending in parallel relation from the lower end of the side flanges of said standard and being bulged outwardly between their ends to form a seat for the candle, means for drawing said halves together to grip thecandle, an angular lever'whose elbow is positionedbetween the side flanges through said flanges and said elbow, a can- 'dle extinguishing cap on the upper end of said lever, and a prong on the lower end thereof to penetrate the candle and hold said 7 lever in position to support said cap free of the candle until said prong is released by meltingof the candle.

2. A candle extinguisher comprising a clamp to surround the candle, a standard rising from said clamp, a lever formed of a bent strip of metal whose two halves are disposed at an angle and joined by an S- shaped portion having an open loop and a closed loop, a pivot pin passing through said closed loop and pivoting said strip to said standard, a candle extinguishing cap on the upper end of said lever, and a pin extending longitudinally of the other end of said lever and secured thereto, the inner end of said pin being received in said open loop and the outer end of said pin being sharpened and extending beyond said strip.

In'testimony whereof I have hereunto set my hand 1n the presence of two subscribing JAMES BAIRD.
