The instantinvention yand the `toolgof saidpatent haveseveral features in .common,land` a common principle of structure in general and attention is directed to said patent for features here disclosed and not here claimed- `An object of this invention is to provide ,certain and new arrangements of the several structural elements whereby to facilitate manufacture of parts, their assembly and the practical operation and application of the new tool in a given bore `and its traverse thereof to cleanthe bore and clean out detritus therein.,
A purpose is to provide for the ready interchange of collapsible piston heads of the tool so that the body assembly and its carriage may be quickly adapted to bores of different sizes.
Afurther aim of the invention is to provide a means to quickly and effectively obtain release ffof the tool in instances where it may become jammed ina bore beingncleaned.
` The invention consists in certain advance- `ments in this art as set forth inthe ensuing disclosure and having, with the above, `additional Yobjects and advantages as hereinafter developed,
*tot clear l Iface.
verse spindles 5 in the outer ends of respective, radial, twin-part arms 6 having `pivots `1v on :the body` member 2,.whereby to `allow `the wheels to have a `swing toward or from the `i'nernberl to compensatefor eitherchanges in the bore size. or non-removable obstacles along the bore 'I'he arms (i` arenormally held in perpendicular, radial position to the member 2 by opposed and balanced tension springs 8 and 9 attached to outer portions of the respective arms and to anl chors` lli-I l at opposite sides of the relative arm pivots 1, on the member 2.
To the tail end,`in thiscase of the member 2, there is attached by a swivel I2, a retracting cable or other appropriate means I3 for pulling back the tool in case it cannot be driven forward by a hydraulic head in the bore of a sewer S, for instance, Ito .a desired outlet or manhole.
The parts just set forth `constitute a form of carriage of self-centering function ina bore to be cleanedor de-sanded. V, s
To accomplish the automatic propulsion of the tool by `a hydraulic head in the sewer there is and whose constructions, combinations and sub` combinations and details of means and the man` ner of operation will be made manifest in the following descriptionofjthe herewith illustrative embodiment; it `beingunderstood that modifications, variations and adaptations may be resorted to Within the scope, spirit and principle of the invention asrit is more directly claimedpresently Figure `1 is a longitudinal elevation, partly sectioned, of thetool as inoperative adaptation.
Figure 2 is a transaxial section on line 2-2, Fig. 1. r t y v Figure 3 is a head-end elevation of the tool.
Figure 4 isa cross-section on line `4--4, Fig.` 1, omitting the rear face of the piston.
Figure `5 is astructural detail section across the axis of distended,`hinged piston elements.`
Figure 6 is a sectional detail of the removable, piston hinge axle assembly.
Figure 7 is a view, in longitudinal broken section, of the piston leaf carrying body element or core.
In this embodiment a stiiltubular or other `form of body element 2 is adapted to be auto- Umatically centered in a bore by longitudinally spaced, annular sets of pilot wheels 4 on transprovided a means in theform of a sufficiently collapsible kite or piston which is self-distending to a normal, at disc form. In the instant disclosure there is slidably related to, and mounted on the body member 2, a second body member 25, here called the coref for distinction, having a` stop shoulder 26 limiting axial sliding action inwardly of the core on the member 2 under the tension of suitable springs 21 anchored at 28 to the forward portion of the member 2 and at# tachedalso to the rear face of related, semi-disc `plates 29e-30.
These plates parts 29 and 30 are,at their diai metrical edges, provided with any suitable interhinging structure, asbight straps 3| looped about a common, diametrical axle composed of aligned, radial rods 32 which are preferably-removably screwed at 33 into opposite sides of the core 25.
` The semi-discs 29--30 form the basal supportof `and for a suitable, diametrically split piston packer 34which may be of firm and exible rubfber or a suitable `substitute sheet form and has abutted edges at the axle. The front (down stream) face of the piston packer-34 is armored by iiat, semi-disc covers 35 rigidly secured against the packer "by bolts 36 or other suitable means also securing, in the assembly, the piston parts 2li- 30. l
The springs 21 aresecured, at their forward ends, to anchors 31, on respective piston parts 29-30, at locations inwardly from the outer ends of diametrically opposite links 38 having anchors 39 at their inner ends on the forward end of the carriage body member 2 and being distally attached at 40 to the margins of the piston parts Therefo-re, if the piston gets stuck in a bore if, then, the main'body member 2 is pulled rearwardly by the retracting cable I3 the links 38 will tug on the piston leaves and tend tofrelatively cold Y lapse them at their .hinge so that the head water being used may flow past the rim of the piston parts and wash ahead interfering detritus or sand, or the whole tool can be pulled back by the cable I3 in some instances of use.
If desired that is a set of braces 4I interposed between the :body member 25 and the leaves to 'i coact with the links 38.
" gree, in operation of the tool, at the rim.
The piston device is provided with a central y port I8 forthe free flow of water forwardly to .Y
I the bore space ahead of the tool to wash downstream the detritus inthe,` bore. Y
. They tool may `or may not be providedcat its he-ad end with apull-in `cable P attached to the vcore 25; which may be tubular as shown;r
; It will lbegs'een that an -cnc-itiit,` of this invention, will include a plurality `of pistonsfgof different packer 34 sizes forl use in different size bores, and
any desired size piston may be quickly mounted in -sition limiting stops.
What is claimed is:
yA kite type sewer washer including a tubular, elongate, rear, body member having a pull back device on its rear end, a fore end body member having a stem slidable axially in the said rear member and having a' pulling hitch, ay pair of :semi-discs `forming a piston and folda-bly connected by a pivot device mo-unted diametrically on said fore member and about which the semidiscs fold in one direction as said members axially shift relatively, rigid braces pivoted at their Aouter ends to outer portions of said semi-discs and pivoted at their rear and inner ends to the .rearbcdy and ya set of tensioned springs connected to therea-r member and to said semiediscs to concurrently contract the body members and tov pull the semi-discs into a common, piston forming plane; sai-d membershaving mutual po- -WILLIA1VI D.
