FUEL FEEDER Aivn CUT-OFF.

To all who 12bitmay concern:

Be it known that I, CURTIS (l. LILLI- enincn, a citizen of the United States, residing at Hutchinson, in the county of Reno and State of Kansas, have invented certain new and useful Improvements in Fuel Feeders and Cut-Oifs; and I do declare the :t'ollowingto be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it uppcltains to make and use the same.

This invention relates to improvements .in liquid :tucl bin'ners, and it has more particular reterence to a means for automatically cutting oil the supply of fuel to the burner in case more fuel is running into the burner than is necessary.

'l'heinincipal object of the invention is to im 'iirove upon Patent #lfl ii-BJQ-l grantedto me on October 16, 1917, for a similar device. I have found from experience that my patented. cut oil mechanism could not be attentively and conveniently used to an. advantage under all circun'istances, especially in connection with heating stoves. In other words, the iatented device can not be effectively installed in small unhandy places. 'lhereiore, as before stated, the present invention is designed to overcome the above mentioned objection. llhat is, it is especia ll y designed to be used. in connection with any conventional type of heating stove, wherein space 1s generally hunted and access to a device oi? this type generally dil'iicult and very unhandy.

Another object of the invention is to provide a device of the above mentioned type which is simple in construction, yet highly cllicient, one which is strong, dm'able, and inexpensive to manufacture.

Other objects and advantages of the invention will be apparent during the course oil? the following description.

of illustration is shown ap'referred embodiment of my invention, the letter S designates a heating stove which includes "a lmrner B, and an annular skirt or base 0, which isdisposed below the burner.

My invention resides in a fuel supply pipe 1 which leads from a suitable "tank to the burner 13. A portion of this pipe is disposed within the base or annular"skirt (i and is provided with a supplemental cut off valve 3, which is normally retained closed by an overbalancing arm .4. This o'verbalancing arm may be of any suitable construction, but I prefer to construct it like the one shown in. my aforesaid patented device. That is, itcousists oi" a cylindrical tubular member This member 5 is socured to the handle oi the valve 3,]which in this instance is a hand wheel 6, by suitable clip 7, which surroimds-it and is soldered or otherwise secured to the wheel 6. This clip, like those in my patented device, is preferably disposed near one end of tubular member as shown, so that it will form in effect a. lever, as obvious.

An overflow pipe 8 extends from the burner B downward and into an overflow receptacle or pan 1). Herein lies the i111- provenient over my aforesaid patented dcviice. That is this pan is of a different design and is so mounted that it may be conveniently emptied, will not be liable to tip over or spill, and is strongly mounted in and it extends entirely beneath. the valve 3,

overflow pipe 8, and the delivery end of the supply pipe 1. Hence, it will be seen that any oil which might leak from any of these parts will be caught in the pan and saved. Pan 9 is provided with a depending leg 10, which in this instance is a narrow metal plate which has its upper end bentover one edge of the pan and secured in any suitable manner. The lower end of the leg bent to form an eye or hearing 11, through which a rod 12 extends, the latter being sup ported by the base C, as shown. This construction permits the pan to swing on a pivot as it fills up. This pan is not designed to be removed.

The short end of the overbalancing arm 4 is provided with a hook 13 on which the loop 14 of the pan 9 is hung. The weight of the empty pan is overbalanced by a metal ball which is placed within the tubular member 5, and when this ball is at one end of the This pan is preferably shallow sary to remove the overflow member opposite to that carrying the hook 1 3, the parts will be in the position shownin Fig. 1. As soon as the weight of pan 10 and its contents becomes sufliciently great to overbalance the member 5, the latter will be moved to a position to close the valve.

The essential difference between the present invention and that of the aforesaid patent is the fact that this device can be placed in a smaller space, and to this end the pan is made more shallow. The location of the pan is another advantage, that is it extends beneath the valve, the overflow pipe and the delivery end of the supply pipe and catches any and all oil which would otherwise be wasted. When in the position shown in Fig.

.1, the pan is substantlally rigid. This prevents it from accidentally tilting and spilling because of the manner in which it is mounted.

This construction also keeps the pan directly beneath the overflow pipe at all times. hen it is desiredto empty the pan, a suitable receptacle is placed beneath it. In my aforesaid patent it is generally necesreceptacle to empty it. This is-a bad feature, in that when the receptacle is lifted off its supporting hook, the overbalancing arm again opens the valve and of course, if there should be any overflow of oil, it would leak on the floor while the receptacle was being emptied. However, this bad feature is eliminated with the present device, as the pan is not designed to be removed.

It is to be understood that the form of my invention herein shown and described is to be taken as a preferred form of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departure from the spirit of the invention or the scope of the subjoined clalms.

Having thus described my invention, I elaim:- 1

1. Thercombination with a burner of a end of said leg having fuel supply pipe connected therewith, a cut off valve in said supply pipe, an overbalancing arm for actuating said valve, an overflow pipe from said burner, a shallow rcceptacle extending beneath valve, overflow pipe and the delivery end of the supply pipe, means for pivotally mounting one edge of said receptacle, and means for supporting the opposite edge thereof 'from said overbalancing arm.

2. The combination with a burner, of a fuel supply pipe connected therewith, a cut off valve in said supply pipe, an overbalancing arm for actuating said valve, an overflow pipe from the burner, a shallow pan extending beneath the valve, overflow pipe and the delivery end of the supply pipe, a depending leg carried by one edge of the pan, the lower end of said leg having a bearing, a rod for pivotally supporting said pan, said rod extending through the bee ring, and means detachably connecting the opposite edge of the pan to the balancing arm, substantially as set :forth.

'3. The combination with a stove, including a burner and a base, of a supply pipe, a portion. of which is disposed within said. base, a cut ofi valve in said supply pipe, an over balancing arm associated with said valve and adapted to hold the valve normally open, an overflow pipe extending from said burner, a shallow pan extending beneath said valve, overflow pipe and the delivery end of the supply pipe, a depending leg connected to one edge of the pan, the lower a bearing, a rod for pivotally supporting said pan, said rod eX- tending through the bearing and being connected to said base and means for detachably connecting the opposite edge of the pan to the balancing arm, substantially as set forth.

In testimony whereof I have hereunto set my hand.
