FEEDING DEVICE.

Specification of Letters Patent.

Patented June 5, I222.

Application filed September 9, 1920. Serial No. 409,249.

T 0 all whom it may concern:

Be it known that I, WILLIAM L. COUL- TAS, Jr., a citizen of the United States, and resident of Seaford, in the county of Nassau, Long Island, and State of New York, have invented a new and Improved Feeding Device, of which the following is a full, clear, and exact description.

In connection with the distribution of fluid, it is well appreciated that numerous devices have been placed upon the market, which have in mind the provision of a chamher or reservoir, into which the fluid flows, and from which the same is permitted to subsequently escape; the inflow being controlled by means of a float operated valve.

In this construction, the arm carrying the float or other parts of the mechanism are set so that the fluid entering the chamber or reservoir may reach a certain predetermined level, at which time the valve controlled by the float or other structure, closes so as to prevent the entrance of further fluid. The amount of fluid retained within the reservoir is thus incapable of variation, except upon the operation of the valve being re-set for a new level.

My invention now contemplates the pro vision of a receiving and feeding device forfluids, which shall include a chamber or reservoir adapted to receive fluid of the type specified, and in which the level of fluid, i. e., the quantity of fluid which the reservoir or chamber is capable of receiving prior to the valve closing, may be automatically varied according to the needs of the element with which it is associated.

This feeder is particularly applicable for use in connection with the burner for which I applied for patent protection on May 5, 1920, the application bearing Serial Number 379,191; although it is not necessarily limited to this adaption;

Reference is had to the attached sheets of drawings as illustratingone practical embodiment of my invention, and in which Figure 1 is a side View of a complete unit showing my feeder as applied in the connection described in the preceding paragraph.

Figure 2 is an enlarged sectional side view of the" feeder taken along the lines 2-2, in the direction of the arrows, of Figure 3.

Figure 3 is a sectional end view, in the direction of the arrows, taken along the line 33 of Figure 2, and

Figure 4 is an enlarged sectional side view taken along the lines 4-4: of Figure 3.

In Figure 1, I have illustrated, as aforestated, my feeder in applied position, and associated with an apparatus with which it will serve a particular purpose, and for which it is primarily intended; and in this figure the reference numeral 5 indicates a boiler of any desired type--with which a ets 9, as a medium whereby the casing is piv-- otally supported.

The entire device may be supported upon any suitable type of bed plate 10, and conventional hydraulic swivel-couplings 11 of any desired type may be utilized for connecting the conduits 8 with sections of pipe 12, which in turn conveniently connect with a fluid strainer 13 positioned in the chamber 14, and a sealed over-flow 15 forming a part of the chamber 16. The chamber 14 is conveniently connected with a pipe 17, in turn communicating with a source of fluid supply, the chamber 16 being provided with an outlet pipe 18, in turn connecting with the burner 6 or other receiving agent.

A secondary chamber is formed within the casing 7, such secondary chamber being conv'eniently provided by positioning a boxing 19 within the casing 7, and around the inlet conduit 8, such boxing being provided with an outlet opening 20 permitting of communication between the interior of the casing 7 and the boxing. In this connection it is to be noted that the opening 20 terminates in any convenient form of valve seat 21, with which a valve 22 co-operates to control the flow of fluid from the boxing 19 into the interior of the casing 7.

This valve, as well as the mechanism controlling the movement of the same, may be of any desired type, such as has been illus trated most clearly in Figure 2, in which itwill be noted that a bracket 23 is attached to the boxing 19, which bracket serves to pivotally support, as at24, a lever 25 having one of its ends rockingly secured, as at 26, to the stem 27 of the valve 22, its opposite end being firmly secured to a float 28.

Thus it will be understood, assuming that the casing 7 is maintained in the position illustrated in Figure 2, that the fluid will enter the boxing 19 through the pipe 12 and conduit 8, and thence be permitted to pass between the valve 22 and seat 21 of the opening 20, and into the casing 7 to a depth at which the float 28 will serve to seat the valve 22, thus preventing a further inflow of fluid.

To now provide means which will permit of the depth of the fluid maintained within the casing 7 being varied, the casing is conveniently formed with an extended portion 29 which extended portion may conveniently project into the opening 31 forming a part of a support 30, which latter-will thus serve as a guide, a thumb screw or other manually operated member 32 being utilized to maintain the casing in one position it this should be desired.

It will be understood, by this construction that the opening or slot 31 will serve as a stop to limit the movement of the casing. .This construction will of course prevent any accidents due to too rapid feeding of the oil, or will preclude any danger of the flame becoming extinguished due to the oil flowing too slowly, it being understood that the flame is extinguished preferably by any suitable means within the feed line 17. It is also to be understood that any desirable structure may be utilized for permitting of the manual "operation, or serving as a stop for the casing, or that this structure may be entirely dispensed with, should this prove to be desirable.

A diaphragm controlled lever 33, or other suitable automatic operating member may be attached to the boiler 5, and by means of any suitable connecting member, such as a chain 34, the extended portion 29 of the casing 7 may be connected therewith.

Assuming now that the pressure within the boiler is extremely low, and that the flame produced by the burner 6 is accordingly to be intensified, it will be understood in the embodiment illustrated, that the lever 33 will actuate the connecting member 31 to permit the outer end of the casing 7 to move upwardly around the pivot formed by the brackets 9 and conduits 8. Assuming that the level of the fluidwithin the casing 7 is that illustrated in Figure 2, it will be understood that the level of the fluid (remaining horizontal) will move to the inner or rearmost portion of the casing, thus causing the float 28 to drop and permit the en trance of further fluid into the same. This excess fluid together with the amount normally flowing into the burner 6 will pass int-o the burner, thus intensifying the flame and increasing the pressure within the boiler. \Vhen this pressure has reached a predetermined maximum, the lever 33 will again operate to .cause the casing 7 to rock downwardly, thus shifting the fluid within the casing to the level indicated at Figure 2, or even beyond the same, resulting in the float '28 rocking upwardly with respect to the casing 7 and seating the valve 22 firmly to prevent the inflow of further fluid. Thus the supply to the burner through the pipe 18 will be diminished to a point at which the valve 22 will again unseat, at which point the diminished flow will be maintained.

This, as will readily be appreciated, will serve to reduce the flame produced by the burner 6, and thus automatically produce a flame proportionate to the needs of the boiler 5, which flame will be at all times automatically varied acccording to these needs.

As aforestated, my improved type of feeder is applicable to any desired adaption,

the same having merely been illustrated in connection'with the burner and boiler for the purpose of showing one practical adaption of my invention, together with structure according to the necessities of this adaption. Obviously numerous modifications of structure might readily be resorted to without in the least departing from the spirit of my invention, which I claim as v 1. A feeder, including a casing formed with inlet and outlet openings, a float operated valve co-acting with said inlet openings for controlling the flow of fluid into' said casing, means for rockingly supporting one of the ends of said casing, and means for swinging the opposite end of the same to vary the level of the fluid in the casing.

2. A feeder, including a casing formed with inlet and outlet openings, a pair of conduits attached to said casing, brackets for rotatably supporting said conduits, pipes connected to said conduits, said conduits being in turn connected to the inlet and outlet openings of said casing, a float operated valve co-acting with said inlet opening and means for swinging one end of the casing.

3. A feeder, including a casing, means for rockingly supporting on of the ends of said casing, a boxing within said casing, a valve adapted to co-operate with a valve seat forming a part of said boxing, said casing being formed With an outlet opening communicating With the interior of said boxing and being also formed With an intake opening communicating with the interior of said casing, a float connected toand controlling the movement of said valve, and means permitting of a rocking of the outer end of said 038111 4. K feeder including a casing adapted to receive a fluid, means for rockingly supporting one end of said casing, a float controlled valve Within said casing, and means for rocking the opposite end of said casing to vary the level of the fluid therein.

5. A feeding device including a casing formed with inlet and outlet openings and adapted to receive a fluid, means for rockingly supporting one end of said casing, a valve cooperating with one of said openings, a float connected to and controlling the movement of said valve and means for rocking the opposite end of said casing to vary the level of the'fiuid therein.

6. A feeder comprising a casing supported to rock about a horizontal axis and having a chamber therein, said chamber being provided With an inlet orifice and an outlet orifice, a float controlled valve controlling one of said orifices, and means for rocking said casing about its axis to occasion a movement of said valve relatively to the orifice controlled thereby.
