CLAUDE E. MELTON, citizens of the United States, residing at Scottsbluff, in the'county 5 of Scotts Bluff and State of Nebraska, have invented certain new and useful Improvements in Boiler-Feed Regulators, of which .the following isa specication.

This invention relates to ,al boiler feed regulator andhas-for its object to provide, yin a manner as hereinafter set forth, :means for controlling the operationof a feed pump to regulatethe supply/of water to a steam boiler. Further objects of the invention/are to (provide, in a manner as yhereinafter set forth, a boiler feed regulator, which is simple in its construction` and arrangement, strong, durable, automatic in its action, thoroughly efiicientgand convenient in its use, readily installed, and comparatively inexpensiveto set up.

v lVith the foregoing view, the invention consists of thenovel construction, combination .and` arrangemenu of parts, as hereinafter more .specificallydescribed and illustrated in the accompanying l drawings, wherein is shown an embodiment of the invention, butL it is to be understood that changes, variations and modifications,A

can be resorted to which come'withinthe scope ofthe claim hereunto, appended.

s In the drawings wherein likev reference characters denote corresponding l parts throughout.y the several views 1 Figure l is a side elevation of a boiler feed regulator, in accordance with this invention.

Figure 2 is a top plan view.

Figure 3 is a fragmentary view in cross section.

Figure 4 is a side elevation illustrating the regulator in operative position during the feed to the boiler.

Referring to the drawings in detail, 1 denotes a support provided with a resilient abutment 2, which extends upwardly rtherefrom as well as being arranged at one end thereof. The other end of the support 1 is provided with a vertically disposed stop member 3 of greater height than the abutment 2. The upper face of the Yabutmentv2 is bevelled, as at 4. The support 1, at a point between the abutment 2 and stop 3, is

formed with a vertically disposed yoke 5 and 4other objects in and between the latterv and the stop 3 with un Opening@ v "i .Arranged above the'suppor'tvl is a water receivingtank 7, which is eccentrically pivoted.`v Depending from the bottom ofthe v tank ,near one end thereof, is an arm 8, which extends within the yoke ffnd is pivotally connected thereto, as at 9.Vv 4 l` Leading from a source of water supply, which can be a tankconta'i'ning accumulated .65 condensate from aheatingsy'stem, is a feed pipe 10 provided with a controlling valve 11. Communicating .with the pivoted LA'end ofthe tank 7 is a flexible pipe branch. 12, which is'connectedfto the lowerv end of theY 'Z0 feed pipe 10, by an elbow coiiplingfl. Vhen the valve 11`is opened the waterw'ill be fed to the tank 7. The flexible pipe `branch 12 opens into'the tank 7 at the top thereof.l Communicating with the pivoted l5 end rof the tank 7, near the bottom thereof,

is a fiexible pipe branch 14, `which is connected by an elbow couplingl to a water line` 16, which opens into 'the feedpump, not

. shown'. The flexible pipe branch`f12'consti- 80k tutes an'inletfor the tank 7, and the flexiblem pipe branch 14 provides an outlet lfor lthe Secured to the top 'ofthe' tank 7 ,centrally thereof, through the mediumlof the holdf ast devicesr 17, ri'sfa'longitudinally extendVJ 4ing -rod 18, whichiprojectsffrom thatend of thetalk 7 to1 v which the branch'es`12and 14 are secured. The rod 18 carries a counterweight 19, which isr adapted to engage the stop 3 for limitin'gfthe Vpivoting movement` in one direction ofthe tank'7 and further to normally maintain said tank in position as shown in Figure 1. The counter-weight 19 is connected to the free end of the rod 18 95 by the hold-fast device 20. f Secured to one side of the tank 7, at that end to which is connected the pipe branches 12 and 14, is a vertically disposed bar 21,

which extends above and depends below the tank 7. Hold-fast devices 22 are employed to xedly secure the bar 21 in position.

Leading to the feed pump, not shown, is a normally closed steam line 23 therefor. The

steam line 23 has interposed therein a valve 105 24 having the outer end of its stem 25 provided with a shifting member 26 therefor.

The member 26 isl formed with a pair of oppositely extending arms 27, 28. Pivotally connected to the arm 27, as at 29, is one end of anactuating rod 30 for the member 26. The connection' 29 provides for lost motion. The rod 3() has its other end pivotally connected, 'as at 3l, to the upper end of the bar 21. Pivotally connected, as at 32 t0 the hrm 28 is one end of the actuating rod 33 for the member 26. The connection 32 provides for lost motion. The other end of the actuating rod-33 is pivotally connected, as at 34, to the lower end of the bar 2l.

` 7Vlienl the elements of the device are in the position as shown in Figure l, the steam lijne is 'Closed andthdfedrmp, 'not Vshown, operating.

`It is thought that the many advantages of a boiler feed regulator, in accordance vvith this invention can be readily understood, and although the preferred embodiment of the invention is as shown and described, yet it is to be understood that changes in the details of constructioncan be had which Will fall Wit-hin the scope of the invention as claimed.
