I OIL BURNER CONTROL MECHANISM Filed Feb. 18, 1927 INVENTOR! Patented Apr. 2, 1929.

OIL- BULRNER-CONTROL MECHANISM.
Application filed February 18, 1927. Serial No, 169,163.
gerous results of the failure of fuel delivery to the burner.
In the accompanying drawings the invention is represented diagrammatically in connection with a certain well-known domestic burner system but it is to be understood that the showing is merely illustrative of the principles of the invention which can be applied to many other kinds of system and can be readily modified to suit the conditions in hand.
Fig. 1 is a diagrammatic View, with parts in section, of one form of the invention.
Fig. 2 is a similar View of a second form of the invention.
In the type of apparatus to which the invention is shown as applied, fuel is delivered to a place of combustion, such as the fire pot 1, by way of an oil line 2 connected with a source of supply represented in the present case by a so-called vacuum-operated feed tank 3, the principle and operation of which are wellunderstood in this art and need not be here described. For the purposes of the present invention it is immaterial from what source the apparatus is supplied with fuel. The delivery may be by gravity, or otherwise, under the control of an electric motor 4 which drives or operates the a paratus as a whole. For clearness of illu ration and since such parts form no part of the invention, the various elements driven by the motor, such for example as the oil pump, air blower, etc. are not shown, it being understood that the result of energizing the motor is to cause fuel and air to be projected into the combustion space of the furnace as usual.
It is also customary in apparatus of this kind to provide certain automatic control or safety devices, such for example as a trip bucket 5 and magnetic oil valve 6. The trip bucket may be connected to the arm of a motor switch? and as usual is ada ted to receive such oil as may drain into it from the fire pot, or the like so that in the event of failure of ignition or undue accumulation of oil from any other cause the bucket will trip and open the motor switch, bringing the apparatus to rest. On the other hand the magnetic valve 6 is adapted to close the oil line against further delivery of fuel to thecombustion space whenever the motor or other controlling circuit is broken. The above are mentioned merely by way of illus tration as readily cooperating with the control mechanism of the present invention but, as will be understood, the invention can be applied to control safetdevices other than those mentioned and, i desired, may be so arranged as to effect its controlling function independently of any such devices.
As stated above the invention has particular reference to the objectionable and possibly dangerous results of the failure of fuel delivery to the burner.
Should'the failure occur due to the oversight of the operator in neglecting to re plenish the fuel supply, the moving-parts of the apparatus will, in some cases, continue to function until the falling temperature attracts attention to the failure of combustion, thereby causing considerable inconvenience and waste of electricity,
On the other hand, should the failure be of a temporary nature, as for example due to the clogging of a pipe or the obstruction of a valve, it may possibly be corrected in a sufliciently short time to result in the resumption of fuel .delivery into a combustion space hot enough to cause an explosion; or, without such an explosion, the combustion space may well be flooded with oil before the apparatus can be brought to rest. x
I have therefore inserted in the oil line a fuel operated device responsive to failure of the oil delivery and operative to prevent the resumption of the delivery of fuel until suitable inspection and readjustment have been made.
4 This device may be a float or any other member capable of effecting a control according to the condition of the oil supply and in both figures of the drawings is shown as a float 8 occupying a chamber 9 intt posed in the oil line. The lowering of the fuel level in the float chamber due to failure or undue diminution of the supply results in the operation of a valve 10 (Fig. 1), or some other device which prevents any subsequent delivery of fuel until the mechanism has been re-set.
In Fig. 1 the valve 10 controls the connection of the float chamber with a drain pipe 11 which may be conveniently directed to discharge into the trip bucket 5, above mentioned, so that the residuum of oil in the b 1 rod 13 which, when the float falls, tips the counterbalanced trip bucket arm 14 and stops the motor.
The device in. the present case is re-set b emptying the trip bucket and restoring the float to its elevated position, this being conveniently accomplished in the form shown in Fig. 1 by temporarily closing the valve 15 which is normally held open by spring 16.
While a particular form of the invention is shown and described' for purposes of illustration, it is to be understood that the invention is capable of embodiment in numerous forms without departing from the principles of the invention as herein explained.
Having now described my invention, I claim: l
1. In an oil burner the combination with a fuel supply line leading to a place of' combustion, of a trip-bucket safety mechanism operated by excess fuel in the place of combustion, a float chamber in the fuel line and a'.' fuel operated member therein adapted to effect the operation of said trip-bucket safety mechanism in response to predetermined lowering of the oil level in said cham- 2.'In an oil burner, the combination with a fuel supply line and trip-bucket safety mechanism, of a reservoir in said line adapted to hold a quantity of fuel sufficient to operate said mechanism, a valved outlet for the reservoir and connections therefrom to the trip-bucket mechanism and a fuel opery ated device for opening said outlet in response to lowering of the oil level in said reservoir.
3. In an oil burner the combination with a fuel supply and a delivery line therefrom to the combustion space, an intermediate chamber in said line remote from the supply and forminga part of the delivery line, an outlet from the chamber other than that to the burner communicating with an unrestricted discharge passage, a float in said chamber and a valve for said outlet adapted to open the same upon lowering of the float, said outlet being at least as large as the delivery line and located at a lower level than that tothe burner, whereby the oil delivered to said chamber is automatically and continuously diverted to said passage by the opening of the valve.
In testimony whereof, I have signed this specification.
JOHN GOOD.
