ARVEL E. SWAIM, OF KANSAS CITY, MISSOURI.

CONTROLLING DEVICE.

Application filed September 16, 1916.

To all whom it may concern:

Be it known that I, ARVEL E. SWAIM, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Controlling Devices, of which the following is a specification, reference being had to the acco-nn panying drawings.

This invention relates to certain improvements in controlling devices and has relation more particularly to a device of this general character especially designed and adapted for use in connection with steam boilers or the like and is an improvement on my co-pending application Serial No. 91,380 filed April 15, 1916; and it is an object of the invention to provide a novel and improved device of this general character including a yieldably supported container in proper communication with the boiler whereby the water level within the boiler controls the direction of travel of the container together with novel and improved means whereby said container controls the water supply to the boiler Or the heating medium therefor.

The invention also has for an object to provide a device of this general character with novel and improved means whereby a signal is caused to operate upon the container assuming a predetermined position.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my im proved controlling device whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I'will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a diagrammatic view partly in elevation and partly in section illustrating a controlling device constructed in accordance with an embodiment of my invention;

Fig. 2 is an enlarged view partly in section and partly in top plan illustrating the rock arm as herein disclosed together with certain of the parts coacting therew1th;

Specification of Letters Patent.

Patented July 2%, 1917.

Serial No. 120,540.

Fig. 3 is an enlarged fragmentary view partly in section and partly in elevation of the rock lever and certain of the parts coacting therewith;

Fig. 1 is an enlarged fragmentary view partly in section and partly in top plan illustrating the bell lever and its mounting coacting with a supplemental, controlling means as herein embodied;

Fig. 5 is a fragmentary view partly in top plan and partly in section illustrating a base mounting of the vertical main pipe and the means for connecting the delivery pipes thereto; and

Fig. 6 is a vertical sectional view taken through the device as shown in Fig. 1.

As disclosed in the accompanying drawings, B denotes a fragment of a boiler of any conventional construction and positioned eXteriorly of the boiler is the tubular upright 1 having its lower end portion operatively engaged with the upstanding sleeve or barrel 2 carried by the supporting plate 3.

Adjustably secured to the upright 1 through the medium of the set screw 4 or the like, is the collar 5 provided with the diametrically opposed and laterally directed knife edges 6 which serve as a mounting for the rock arm 7 said arm 7 being provided with a supplemental member 7 so that the same may have requisite engagement with the knife edges 6.

One end portion of the arm 7 is provided with an enlarged opening 8 through which is disposed the pin 9 square in cross section and which is carried by and intersects the bifurcated portion 10 of the plug 11 detachably engaged with the upstanding pipe 12 arranged at the axial center of the container C. By employing the knife edges 6 and the square pin 9, it will be perceived that the arm 7 may rock with a minimum of friction and that the arm 7 may also coact with the plug 11 in a similar manner.

In communication with the pipe 12 is the horizontally disposed pipe 1a which is also in communication with the vertically disposed pipe 15 positioned beyond the container O and in alinement with the upright 1.

The container C is also provided at its axial center with the depending pipe 16 in communication with the horizontally disposed pipe 17 which is also in communication with the vertical pipe 15. The upper end of the vertical pipe 15 is in com1nunication, through the medium of the flexible pipe 18, with the upright 1 at a predetermined point above the collar 5 while the lower end of the vertical pipe 15 is in communication, through the medium of the flexible pipe 19, with the upright 1 at a predetermined polnt below the container C.

The upper end of the upright 1 is in communication, through the medium of the p1pe or conduit 20, with the steam dome S of the boiler B while the sleeve 2 hereinbefore referred to is in communication, through the medium of the pipe 21, with the boiler B adjacent the bottom of said boiler.

Adjustably engaged with the end portion of the arm 7 remote from the plug 11 is the poise 22 whereby it will be perceived that the arm 7 may be so balanced as to initially maintain the longitudinal or vertical center of the container C substantially flush with the normal water line within the boiler B,

said water line being indicated in the accom-- panying drawings by dotted lines as at a.

V denotes a valve of any ordinary or preferred type interposed in the water feed pipe P discharging into the boiler B and the stem 23 of said valve V is provided with a rock arm 24 which is engaged with the lower extremity of the rod 25 which extends upwardly and has its upper end portion disposed through the eye 26 in swiveled engagement with the arm 7 as indicated at 27, said rod 25 being held against longitudinal movement independently of the arm 7 through the medium of'the set screw 28 or the like.

It will be at once understood that the connections between the boiler B, the steam dome S and the container G will maintain the same water level in both the boiler B and the container C, and as the water level lowers the cylinder or container C will rise under the influence of the poise 22, whereupon the valve V will be opened to permit a supply of water to be fed within the boiler B.

As the water level rises the increased weight afl'orded by the water within the container C will over-balance the poise 22 and cause said container to lower and close the valve V whereby it will be at once noted that a predetermined water level within the boiler B will be automatically maintained.

If for any reason the water level should become unusually low and a suflicient supply of water could not be supplied, I find it of advantage to employ an audible signal herein disclosed as a conventional steam whistle 29 in communication with either the upper portion of the upright 1 or the conduit 20 leading from the steam dome S and having its operating arm 30 provided with the rod 31 loosely disposed through the eye member 32 in swiveled engagement with the arm 7 as indicated at 33, and at a predeterminedpoint below the arm 7 said rod 31 is provided with the adjustable stop or shoulder 34. By this arrangement it will be per ceived that as the container C rises, the stop or shoulder 34 will be engaged by the eye 'member 32 whereupon the continued rise of thc'container C will result in a downward pull upon the rod 31 with the result that the whistle 29 will be caused to sound.

I'have alsofound in practice that my improved device may be employed with con venience and facility for controlling the delivery of liquid fuel when such type of burners are employed in connection with the boiler, and as herein disclosed, P denotes a pipe leading from a suitable source of fuel supply to a conventional burner (not shown) positioned beneath the boiler B, and interposed in said pipe P is a valve V, the stem 35 of which being provided with the rock.

upright 1. The forward or outer end of the horizontal arm 39 of the bell lever 40 is provided with the elongated slot 45 through which is directed the rod 25,and adjustably secured to the rod 25 above the horizontal arm 39 and through the medium of the set screw 46 or the like, der 47 whereby it will be continued or excessive rise of the container C under the influence is the stop or shoul- 48 of the bell lever 40 from the weight49 aflixed to the rod 37, whereupon the valve V will be adjusted into will be understood that the valve V is reset or opened manually. i

As herein embodied, the weight 49 is provided with an annular flange 50 with which coacts the hookextremity 51 of the vertical arm 48 as is believed to be clearly illustrated in Fig. 1 of the accompanying drawings.

As is particularly illustrated in Figs. 1, 5 and 6, of the drawings, the pipes P. and P are loosely disposed through the outer ends of the cross head 52 suitably secured to the upright 1 adjacent the lower end thereof through the medium of the set screw 53 or the like and that said pipes P and P. are,

held against longitudinal movement independently of the cross head 52 through the medium of the set screw 54 or the like.

l/Vhile the pipe P has been defined as'rcoacting with a liquid burner, it will be understood that if preferred the same may lead from a suitable source ofwater supply and perceived that upon of the poise 22, the

horizontal arm 39 will be depressed or forced downwardly so'as to release the {vertical arm a closed position. It-

be in communication with the boiler B for the same purpose as the pipe P hereinbefore referred to. As this latter arrangement is believed to be self-evident, a detail illustration thereof is deemed unnecessary.

From the foregoing description, it is thought to be obvious that a controlling device constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as hereinafter claimed.

I claim:

1. In combination with a boiler, a container supported for vertical movement, said container being in communication with the boiler above and below the Water line of the boiler, means for balancing the container, a valve, an operative connection between the valve and the container whereby said valve is under control of the movement of the container, a second valve, an operating rod therefor, a bell lever mounted for rocking movement and detachably engaged with the operating rod of the second valve, and means under control of the connection between the container and the first named valve for disengaging the bell lever from the controlling rod of the second valve, said bell lever being provided with an opening through which the operating rod of the second valve is loosely directed.

2. In combination with a boiler, a tubular upright positioned exteriorly thereof and in communication adjacent its top and bottom with the boiler at points below and above the water line of the boiler, an arm connected intermediate its length with the upright for rocking movement, a container, pipes in communication with the container through the top and bottom thereof, a third pipe in communication with the first mentioned pipes, an upright connection between the end portion of the arm and the pipe in communication with the container at the top thereof, flexible conduits in communication with the opposite ends of the third named pipe and with the tubular upright at points above and below the water line of the boiler, and a poise co-acting with the opposite end portion of the arm.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
