oil will be automatically sliut off at thesource of supply in case of over feeding of the burner, or of an excess leakage of Oll from burner supply pipe, such as wouldresult from broken pipes, ivalves 01"COI1'116Ct1'OI1S.
Another object of'my invention is to provide a device of the character described, which may be readily adjusted to meet the requirements ofthe various sizes and. capac1- ties of such oil burners, as are nowingeneral use for domestic'and industrial'heating.
With the foregoing and other objects in view, which will appearas the descr ption proceeds, my invention resides inthe COIlfl. bination and arrangement of parts, and in the details of construction hereinafter ,described and claimed, it, being understood that changes in-theprecise embodiment of the invention herein disclosed may be made within thescope of what is claimed, without departingfrom the spirit of the inven tion. or I Referring to the drawings: Fig.1 is a top iew of my device, with part removedfor convenience of illustratlon. Fig. ,2 is a side view of my device, with part removed for convenience of illustration. Referring to the drawings in detail. reference characterl designates the ",cup-shaped bottom section of :a valve-body, which is so formed as to constitute the bottom and side walls of a float chamber 13. The top section of valve body iaseshown at 2, forms the top covering of float chamber 13, and is so constituted as to accommodate the assembly of certain valves and connections, and con tains a series of inter-communicating chambers and passage ways necessary to the proper operation of said device. The valve body sections 1 and 2 as shown, are joined at flange 27 by means of screws 25. The intake port 4 and discharge port 5 are tapped for standard iron pipe connections. A vent pipe 7 provides means for the admission of air into float chamber 13, which is necessary to the operation of float-valve 15. The air vent cock 6 provides means for exhausting the air from float chamber 13 when adjusting the device for operation, and when re-' 1926. Serial No. 11 4,511.
adjusting same following an automatic 'shut ofl'-operat1on The float valve 15 being attached'to'float 3 as shown, is thereby raised and lowered in vunisonwith said float, as in the presenceor 'absenceof fluidin float ohamber'13. -'The floatf3 is of the air tight sheet metal type,
constructed of light gauge brass or copper sheet, and 1n general contour conforms r-closely to that of the float chamber 13 which incases it, due allowance being made iii its dimensions to assure freedom from contact with side walls of the latter and to permit ;-raising and lowering of said float. A'center guide pin 24 depending from lower center of floatB, serves 'to securethe position of said float in proper alinement 'withfloatvalve port 12. v I
I install 'jmy'device in the "oil Ifeed pipe intake port 4, and the burner supply pipe at discharge port'5; During normalroperation, the oil enters intake chamber 8. 'at intake port 4, passes up through regulating valve port 9, thence through connecting p'assage-away 10to float valve chamber 11 thence "through float-valve port '12 to float chamber 13 and discharging at discharge port 5.
After such automatic shut off operation as described, I proceed to readjust the control valve for operation as follows: I first open vent cock 6 to permit the escape of air from float chamber 13, then I re-flll said float chamber with oil by opening by-pass valve 17 and when oil appears at vent cock ,6, I close it tightly and then close by-pass valve 17 so that the device is again ready for operation. V
I Having thus described my invention in detail, what I claim is new, and desire to secure by Letters Patent is:
1. In a safety controlvalve, a valve body comprising an intake port and a discharge port, each adapted for standard iron pipe connections, a vent pipe connection providing means for the intake of air, a vent cock connection providing means for the exhaustion of air, a screw-adjusting regulatin valve interposed between said intake ant discharge ports adapted to control the maximum flow of fluid to be permitted, a floatinto said float chamber direct from actuated valve interposed between said regulating valve and discharge port operating to permit the free passage of fluid when the float is raised by the weight of the fluid present in the float chamber incasing it, and to automatically shutoff the flow of fluid entirely when said float is lowered by exhaustion of fluid from said float chamber, as will be effected by a discharge of fluid at a rate in excess of that for which said regulating valve is adjusted, a by-passvalve controlling direct. communication between the intake and discharge ports through said float chamber, providing means for adjusting said float-actuated valve in operating position.
2. In a safety control valve, a valve body comprising an intakeport and a discharge port. each adapted for standard iron pipe connections, a vent pipe connection providing means for the intake of air, a vent cock conncction providing means for the exhaustion of air, a regulating valve interposed between passage of fluid at a rate of flow not exceed- 7 ing that for which said regulating valve is adjusted, and to shut ed the passage of fluid entirely when the rate of flow of fluid at discharge port exceeds that for which said regulating valve is adjusted, a fioat chamber interposed between said float-actuated-valve and said discharge port serving to incase the float member of said float-actuated valve, means for supplying air to said float chamber, and means for exhausting air therefrom as necessary to the operationof said float member, a by-pass valve providing means for adjusting said float-actuated valve in operating position by the admission of fluid the in take port chamber.
In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.
