I No. 864, 664.

To all whom it may concern:

Be it known that 1, CHARLES MILD, a citizen of the United States, residing at Mount Vernon, in the county of Knox and State of Ohio, have invented a new and useful Improvement in Cleaners for Steam- Condensers, of which the following isa specification.

My invention relates to improvements in cleaners or steam condensers.

The object of my invention is to provide a cleaner of this character which is adapted to operate on the inner water-cooled surface of a condensing cylinder for removing any deposits which may adhere to the cylinder. The water-cooled surface of the condenser is at all times free from any deposits a'nd the water flowing over the same has a greater condensing action upon the steam within the cylinder.

Another o'oiect of my invention is to provide a more simple, cheap and effective cleaner which is readily adjusted to fit cylinders of different diameters and also provided with means for varying the pressure of the brushes and scrapers on the water-cooled surface.

In the accompanying drawings: Figure 1 is a vertical sectional view of asteam condenser, showing my improved cleaner applied thereto; Fig. 2 is a transverse sectional view taken on the line z:c of Fig. l; and Fig. 11' is an enlarged detail plan view of the brush and scraper.

Referring now to the drawings, 1 represents the condensing cylinder, which, as shown, is composed of an outer vertically disposed cylinder 2 and an inner inclined cylinder 3 forming a steam condensing space 4 between the same. lhe upper and lower ends of the cylinders have connected thereto plates 5 and 6 which close the upper and lower ends of the steam condensing chamber 4. The said condenser is supported upon a base 7 and is provided with a steam supply pipe 8 a short distance above the base. The inner inclined cyl indcr 75 at its upper end is provided with a water supply pipe 9 end deflecting plates 10 and ll for deflecting and spraying the water against or upon the inner face of said cylinder. The water thereupon travels downwardly in :1 thin sheet over the cylinder and keeps the same comparatively cool.

It has been found in condensers of this character that the inner cylinder 33 soon becomes couted with a deposit from the water and the c: udcr does not readily transmit the cooling effect of the water to the inner lace oi the cylinder. In order to prevent this collection or deposit on the inner cylinder, 1 provide a vertically disposed shaft 12 rotatably supported in the center of the inner cylinder 3, the said shaft being supported at its upper end by a transversebar l3 and its lower end by a plate 14 and is held against longi- Specification of Letters .Estsnt.

tudinal movement. The upper end of the shaft extends a distance above the upper end of the cylinder and is provided with a worm gear and meshing vvith the said worm gear 15 is a. Worm 16 which is carried on the shed 17 of a water motor 18. The water motor may be driven through the medium of the water supply to the inner cylinder, thus the said shaft is Caused to continually rotate,

The. shaft 12 at its upper and lower ends and at the center is provided with oppositely arranged radially extending arms 19 and El) which are rigidly secured to the shaft by set-screws 2]. The outer ends of said arms have rigidly mounted therein vertically disposed rods 22 and 23 which extend parallel with the shaft. The said rods have loosely mounted thereon the arms 24 and 24 which are provided on their inner ends with segmental plates 25 having segmental slots 26 through which passes a set-screw 27 which enters the arm 24 and whereby the arms may be adjusted in any position. The outer ends of the arms extend adjacent to the inner face of the cylinder Ll and support the brushes 28 and scrapers '29. The scrapers and brushes bear against the inner surface of thccylinder 3 and keeps it absolutely free of any deposit. The scraper 29, as shown, is of an elongated shoot of metal having a series of transverse slots 30 extending from one edge about three-fourths of the width of tho scraper. Carried by theoutcr ends of the arms 24 are bolts 31 which pass through said slots and securely fasten the scrapers to the arms, the slots allowing for the inward and outward adjustment oi the said scrapers. From the drawings, it will be seen that the scrapers are not made oi a single piece extending the whole length oi the cylinder, but are made in sections and the same slots 30 are used for securing the said sections together for hunting a continuous scraper. The brush 28 is likewise secured to the arm 24" by the bolt 31, but instead of having slots they are provided with openings- 32 through which the bolts 31 pass. These brushes need no adjustment to or fr in the cylinder 3 as the elasticity of the bristles of the brush does not require as fine an adjustment as do" the scrapers.

Having thus fully described my invention, what I claim as new and desire to secure by L tters Patent. is:

A cleaner for steam condensers comprising :1 rotary shaft. radially extending ui'ms curried by the said shaft, vertically disposcdbursrigidly carried by the outer ends of said arms and parallel with the shaft, brush and scraper c ylng members loosely mounted on the sold bars and having segmental slots at ,their inner err/s, passing through said slots for udjuntubl; holding said members. 'oolts passing through the outs ends of said members and brushes and scrapers secured thereto by the bolts.

set-screws 2.v A eleaner for steam condensers, comprising a rotary' respectively, through which they .=zi -1e secured to the said shaft, radially extending arms carried by the shaft, vertically disposed bars carried by the outer ends of the said segmental slots at their inner ends, setscrews passing *through said slots for adjustnbiy holding said members, bolts passing "through the outer ends of said members,

- And brushes end scrapers having openings and slots,

members and by means of which they are secured together. In testimony whereofl i iin'we signed my name to this specification in the present-e of two subscribing witnesses.
