GEORGE SCHLEMMER, F NEW YORK, N. Y.
ooNnUr'r-CLEANING DEVICE.
Specification of Letters Patent.
' Application led J une 19, 1 915. Serial N o. 35,052.
To all whom t may concern Be it known`that I, GEORGE SCHLEMMER, a citizen of the United States, residing at New Y York, in the county of New York and State of New York, have invented certain new and The present invention has to do more particularly with improvements in the cleaning element itself and the same is herein shown to be o'f the bristle or brush type.
i My invention includes a flexible spindle o which isV strung a series of bristle or brush units of a sufficient number to. form a cleaning element of elongated contourso that a relatively extensive length of periphery will be presented to the interiorvof the conduit. Y
A further object of the invention is to provide the cleaning element with one or more imperforate diaphragms the function of which is to form an abutment to the circulating liquid so Aas to cause the latter to advance the cleaning element through the conduit. This feature of my invention involves an improved type of diaphragm -which is preferably flexible and which is so constructed that fiexure of the same will not impair the efficiency of the diaphragm when the same acts to prevent passage of water past the cleaning element.
A. further object of the invention is to provide an improved type of brush unit wherein the bristles are firmly secured in disk or final form.'v by an improved metal mounting which is bent into a bristle anchoring position or shape when the unit is formed.
My invention also involves novel forms of flexible spindles, the construction of which is such that the maximum flexibility is obtained in addition to firm anchorage of they ranged at opposite ends of the cleaning element to effectively guide and to assist in advancing the cleaning element through sharp turns in the conduit.
Other features of novelty will be more Afully described in connection with the accompanying drawings and will be more particularly pointed out in and by the appended claims.
In the drawings- Figure l is a longitudinal sectionalyiew of a form of my invention, with metal sep arating rings between the bristle units.
Patented Mar. 6, 1917.
Fig. 2 is a view in elevation 0f a cleaning element showing the same as it would appear in negotiating a sharp turn in the conduit, the separating rings being alternatelyr y of rubber and metal.
Fig. 3 shows a modified form of my invention,
Fig. 4 shows a further modification, 'Fig 5 is a transverse sectional view showing one of the brush units in elevation,
Fig. 6 is a transverse sectional view illustrating one of the diaphragms in elevation,
Fig. 7 is an edge view of the diaphragm shown in Fig. 6,
Fig. 8 is an enlarged sectional view of one of the brush units during the method of formation thereof,
Fig. 9 is a view similar to Fig. 8 showing the unit completed.
Like characters of reference designate,
corresponding parts throughout the different figures of the drawings.
First referring to the preferred form of my invention, and more particularly to `Figs. 1, 2, 5, 6 and 7, it will be seen that my imvproved flexible spindle'includes a length of flexible wire 1 of sufficient size to afford the required tensile strength and also provide for ,the required flexibility. Sleeved on the wire core l is a flexible tubing 2 which may be of rubber and which. provides for a sufficient diameter in order to lfacilitate the location thereon of the brush units. Eind connecting heads 3, preferably of metal, are bored to fit the wire core land said heads abut against the end of the sleeve 2. Said connecting heads are shown securing the wire core l by entering screws 4 lwhich are threaded into radially disposed threaded bores which intersect the axial boresof said heads.- In the' present construction, the connecting heads are provided with hubs 5 of a diamef ter equal tothe sleeve 2 lso that shoulders 6 are formed to receive the endmostunits, Which -Will presently be described.
I will next describe the particular novel construction of the brush units-before detailing the manner in Which they are assembled upon the flexible spindle.
Referring to Figs. 8 and 9,'a thlmble 1s shown comprising sections 7 and 8 which are initially shaped as shown in Fig.8, the outer margins having va greater diameter than the inner margins. The inner margln 9, of section 7, telescopes or seats in an offset margin 10, of section 8 so that there W1ll `be formed an annular flaring cavity extendling peripherally about said section. Lengths of bristles 11 are secured at their centers in said cavity by a binding cord or W1re 12 so -that the ends of said bristles will project radially from said thimble when the same is completed. I preferably locate the bristles in sufficiently compact form to form a c omplete disk, as shown in Fig. 5. It is also desirable to shellac 'or otherwise treat the bristles so that they will adhere to one another thereby preventingjthe formation of any gaps or spaces in the continuity of the ldisk which might otherwise be caused by circumferential displacement of the bristles. After the parts have been assembled as shown in Fig. 8, the thimble sections -are placed under pressure so that the outer marglns thereof-Will be collapsed toward each other and against' the interposed bristles to clamp the latter in place as shown in Fig. 9. By reason of the clamping pressure of the thimble sections,.and because of the shellac applied tothe bristles, the latter Wll be firmly heldl in place upon the thimble in true disklike formation.
ext referring to my improved abutment diaphragm, and more particularly to Figs. 6 and 7, 13 designates a clamping thimble similar in all respects-to that'described in Connection with Fig. 8,'and between the vinargin of Which is firmly compressed a plurality of sheets 4or disks 14 and 15, onlyl tWo being shown in the present construction. These disks may be composed of sheet rubber or other flexible material which is impermeable to liquid and each sheet is provided with a plurality of radially disposed 'V-shaped slits 16. The slits 16 result in the formation of radially disposed sections -17 which are free to be flexed when under pressure. The disks Maand 15 are disposed in the thimble'13, in staggered relation, as shown in Fig. 7. Thus imperforate sections 17 will be abreast of the slits of the abutting disk so that flexure of the radial sections 17 will not form gaps through which the liquid could pass, the diaphragm remaining' in all positions substantially imperforate to liquid. -i
Now referring to Fig. 1 it will be seen-that the brush 'units are of larger diameter neartween each of the brush units is 'interposed a spacing element and the same are shown in Fig. 1 as consisting of rubber rings 1'8.
No spacing element is shown between those units which inclose the diaphragms as it is desirable to have the diaphragms inclose relation With the brush units, and the diaphragms constitute sufficient spacers.` It
Will be understood that after the' brush units and diaphragms have been strung upon the spindle in close relation With each other and With the endmost unit seated against one of the connecting heads, then the remaining connecting head Will be secured in place.
In Fig. 2 Iehave shown va portion ofa conduit as designated at 19 illustrating themanner in which the brush cleaning element can negotiate a sharp turn. The' cleaning element shown in Fig. 2 is provided With spacing elements comprising alternately arranged rubber spacing rings 18v and metal spacing rings 20. Near the ends of said element I provide coiled Wire spacing elements 21 which are preferably of resilient spring Wire so that When the units are assembled, i
through and through the strands of Wire v core 1, or in' any other suitable manner. A suitable space is provided between these guiding elements and the connecting heads 3 so that as the cleaning element approaches a sharp turn, such guiding element, in advance of the brush, will engage the Wall of the conduit and act to flex the advance end of the brush in accordance With the curvature of the turn in the conduit. 'Furthermore, these guiding or propelling elementsJ are suiiciently large in size to approximately fit the interior of the conduit With a good Working'clearance so that they will arrest the flow of liquid and thereby assist in the propulsion of the cleaning element through the conduit. This will be especially so 'when the advance guiding vele'mentinitially enters a 'turn' in the conduit.
Usually, the conduit Will be of less diameter than the normal or maximum unflexed diameter of the brush Iso that as thelatter passes through the conduit the peripheral portions of the brush units'an'd diaphragms core, a plurality of cleaning units of the conduit with considerable pressure, thereby greatly enhancing cleaning action. In the form shown in Fig.'3, all of the spacing elements are formed of s1mple metal rings 24 and I omit the guiding elements 22. In,the, form shown in Fig. 4, the spindle is formed of a wire core 25 about which is disposed a sleeve composed of a coil of spring wire 26 which will be seated against the hubs 5 of the end pieces 3 in a manner similar to the construction. shown in Fig. 1. The spring sleeve 26 will preferably be placed under' compression when the brush units are assembled thereon and I provide spacing elements 27 composed of simple metal rings. The diaphragms and brush units will be the same in construction in all forms of the invention, but I wish it to be understood that it is not essential that the diaphragms should be composed of flexible material as owing vto my improved construction, they could be formed of metal.
It is believed that the advantages and utility of my invention will be clearly' understood from the foregoing description and while I have herein shown' and described specific forms of my invention, I do not wish to be limited thereto except for such limitations as the claims may import.
I claim: j
