My invention relates toskimmers for use in cleaning boiler water, used in conjunction with settling systems to remove suspended matter fromthe water. u
Thepurpose'of my'invention is to provide a novel form ofinlet that is at once wiell adapted `to meet the needs of service and easy and inexpensive to manufacture.
A further purpose is to have efficient vskimming whatever the water height within the range of water height that may be met in practice having relatively spaced split pipes branch upwardly through the water to the steam space from an eduction main beneath the water. The pipes may extend vertically or at anyangle. j
A further purpose is to have the splits in the pipes progressively Wider toward the top.
A further purpose is to relatively stagger the direction of presentation of the splits. Further purposes will appear in the specification and in the claims.
I have preferred to illustrate my invention by but one main form, with a minor modification, and have selected a form that is efficient in operation and which illustrates particularly Well the principles involved.
This application is a continuation of the subject matter referred to in my applica-` tion No. 254,367, filed September 16, 1918.
Figure 1 is a longitudinal section of one form of boiler with one of my skimmers in position.v v
Figure 2 is a section of Figure 1 to enlarged scale taken upon the line 2-'2 and showing means to settle out dirt removed from the boiler. p
Figure 3 is a brokenelevation of a portion of the skimmer system showing top skinnner pipes.

Figure 6 is abroken elevation ofa por-` tion of the skimmer system modified in minor detail and showing end views of the skimmer pipes.
In the drawings similar numerals indicate like parts. l
Describing in illustrationand not in limitation and referring to the drawings,- I I show in Figures 1 and 2 my skimmers installed in a boiler 15. The eduction main SKIMMER INLET FOR isoInERs.
This application led `March 17,
16 extends longitudinally of the boiler just above the fire tubes 17 and below the water level within the boiler and carrie-s the skiinmer inlet pipes 18.
The skimmer inlet pipes branch from long-sweep Ts 19 of the eduction main and extend upwardly into the steam `space. 20 above the water. They are slit longitudinally along diametrically opposite lines at 21 throughout a verticalheightcovering the range of variation of water level Within the boiler and preferably the sides of the slits are progressively spread toward the upper ends, thus properly functioning what` ever the water level.
The skimmer inlet pipes are conveniently made by sawing sections of pipelongitudivnally to form the slits. The split sections may-be permanently sprung open to desired spread or may be sprung over a wedge 22 as shown in the illustration, this clamped Wedge being held to place by a suitable cotter pin 23.
By splitting and spreading the pipe the outer end of the pipe section remains open except for the spreader bar and retaining pin leaving half the cross-section of the pipe interior on each side of the bar for flow in at the end. This gives sufficient crosssection throughout for uninterrupted flow in each half section of the pipe including the outlet opening at each side of the bar. This provides uniformity and smoothness of movement and the same contour of engaging surfaces (i. e., the interior wall of half the pipe) diflicult otherwise of attainment. It is subject of cour-se to interruption by transverse lines of flow through the slits. At the same time themethod of 1nanutacturc is simple and inexpensive and leaves a terminal at one end which is unslitted and unspread and which can readily be threaded for engagement within or upon suitable fittings.`
The splits of the adjacent pipes are preferably pre-sented 'relatively at right angles to each other to afford a somewhat better diversity of inlet direction. Obviously too the split pipes may be relatively in line as indicated in Figures 1 and 2 or not, according to circumstance and the particular arrangement giving best surface skimming.
It is advantageous to have the Ts 19 long-sweep, in order that there may be minimum chance for collection in` them of dirt skimmed from the boiler', as Well as minimum resistance to the circulation used in automatic skimming, and the arrangement of Figure 6, with other advantages, gives particularly easy sweep at the Ts.
The settling drum 24 is connected on one side through valve 25 by pipe 26 to the eduction main and on the other side by. pipe 27 and valve 28 into the bottom of the boiler. Radiation surfaces 29 are preferabl provided around the pipe 26, around t e settling drum and around the pipe 27, the rapidity of automatic circulation from the skimmer pipes into the eduction main and thence to the settling drum and from the settling drum back to the boiler depending upon relatively low temperature in the vertical portion of the circuit outside of the boiler, and rapidity of settling in the drum increasing with lowness of temperature in the drum.
The drum is periodically blown olf at the blow-oil' pipe 30.
In view of my invention and disclosure, variations and modifications will doubtless become evident to others skilled in the art, to meet individual whim or particular need, and I claim all sucli in so far as they fall within the reasonable spirit and scope of my claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is v 1. An inlet device for a skimmer system which consists of a longitudinally extending collecting conduit and a plurality of spaced upwardl extendin slitted pipes connecting therewitli, having the slits extending parallel to the axes of the pipes and in diifercnt directions in adjoining pipes.
2. An inlet device for a skimmer system which consists of a longitudinally extending collecting conduit, a plurality of upwardly extending pipes connecting therewith, slitted longitudinally of the ipes, the Walls of said splits being separated) to cause the adjoining edges of the slits to diverge and the slits opening in different directions in adjoining pipes.
3. An intake device for a skimmer system comprising a horizontal conduit and a plurality of u wardly extending inlet devices connected tierewith at intervals along the conduit, each having one or more side openings and the openings in adjoining sides facing in diierent directions.
