RUSSELL B. KINGMAN, ORANGE, NEW JERSEY SWAB.
Application filed November 3, 1925. Serial No. 86,489.
This invention relates, generally, to an instrument in the form of a swab for cleaning tubular or cylindrical structures of various kinds, such e. g. as milk Pasteurizing tubes and the like. i
This invention has for its principal object to provide a novel construction of swab, either of the dry type, or of the fountain type having means for delivering water,
steam or other fluid in connection with and in aid of the cleansing operations adapted to be performed by the swab.
With the general object of this invention in view, the same comprises a novel construction of swab head provided with novel scouring elements made of all-metallic fabric, or composite vegetable fiber and metallic fabric adapted to furnish an eflicient abrasive material calculated to produce a thorough scouring eflect upon the surfaces v to which it is applied.
This invention has for a further object to provide a novel construction and arrangement of dismountable flexible and reversible swab elements, together with, a novel means for operatively coupling said flexible and reversible swab elements with the head of the device.
Other objects of this invention, not at this time more particularly enumerated, will be clearly understood from the. following detailed description of the same.
With the various objects of this invention in view, the same consists, primarily, in the novel construction of swab hereinafter setforth; and, the invention consists, further more, in the novel arrangements and combinations of the various devices and parts, as well as in the details of the construction of the same, all'of which will be hereinafter more fully described; and then finally embodied in the appended claims.
The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the 'iiovel construction of swab made according to this invention, and showing the arrangement of the same when .passed through a tube or the reversing functions of the flexible swab elements, .4 f
the like in one direction: and Figure 2 is a,
the swab when passed through a tubeor the Figure 3 is a side elevation of one form of the swab head and detachable keeper member for coupling'the flexible swab elements therewith.
Figure 4 is an enlarged side elevation of the s'wab head illustrating a covered form thereof, and also showing the. detachable keeper member ready to be applied thereto. Figure 5 is a vertical longitudinal section of a covered form of swab head with the flexible swab'elements operatively coupled therewith; and Figure 6 is a fra mentary cross section,-takenon line 66 in %igure 5.
Figure 7 is a side elevation of a fountain type of swab head, a portion of the covering material being broken away; Figure 8 is a vertical longitudinal section through the same; and Figure 9 is a vertical .sectional view of a modified form of detachable kee er member which. may be employed wit saidfountain type of swab head, if desired. j
Figure 10 is a diagrammatic lan view to illustrate one method of assem ling a plurality of flexible swab elements; and Figure 11 is adiagrammat'ic perspective view of two flexible swab elements, as disposed for superimposition one on the'other. Similar characters of reference are employed in all of the hereinabove described views, to indicate corresponding parts.
Referring now to said drawings, the reference character 12 indicates a swab head in the form of a rigid elongated body, preferably-of cylindrical conformation. Suitably attached to the lower end ofsaid swab head is a handlemember 13 of desired length suitable to the particular conditions of use to which the'swab is to'be put. The outer or free end of said swab body 12 is rovided with an axially aligned internal 7 screw threaded bore 14. The reference character 15 indicates a-keeper member which referably comprisesa relatively short ri corresponding in diameter to the diameterof said swab body 12; said kee r member is provided at itsinner end with a screw threaded shank 16 adapted toscrew into the bore 14 of said swab body-12. In the sim lest form of my novel swab device, the swa body 12 and keeper member 15 may be uncovered as tetlf'eir exterior surfaces, a ndicated by the full l nes in Figure 3; on be other hand,
. vegetable fibre strands For example, jute threads gimped with flat and vegetable ible fabric is preferably provided with me- 36 stood, however,
' elements 17 such as above described, suitable area are provided with central open- 40 ings or perforations 18, and are superim-.
'swab head 12, by
" 16 through the aligned perforations 18, and
for certain classes of work it may be desir able to cover the exterior surfaces of either I or both the swab head 12 and keeper member 15 with a covering of abrasive material, in-
5 dicated by the dotted-lines in said Figure 0 rality of flexible swab elements. These swab elements are made of a metallic abrasive fabric, which is either knitted or woven from metallic wire, preferablyof a noncorroslve metal such as copper, to provide 15 ;a relatively coarse fabric of highly eflicient braslve character. The fabric material may consist of an all metal type,'or it may consist of a composite type suitably combining with metallic strands.
copper wire, may be interwoven or knitted to provide the fabric; or such metal gimped jute threads may be suitably interwoven with either or fiber cross threads. The flextallic material which is calculated to produce. the desired abrasive eflects adapted to provide adequate scouring efiiciency. Where 30 strong abrasive effect is the desideratum, an
all metallic fabric may be used; but if a certain amount'of absorbent eflect is desired, the combined metallic and vegetable fiber fabric may be used. It will be underthat if desired non-metallic fabric swab elements may be employed. A plurality of flexible abrasive fabric $37311)! an o posed one upon the other, preferably in'an irregular manner, as illustrated in Figures 10 and 11. When a desired number of said flexible swab elements have been thus as- 45 'sembled together, the same are laid over the-outer or free end of the swab head 12,
' with'their perforations 18 aligned with the threaded bore 14 of the latter, whereupon ,the keeper member 15 is attached to the passmg its threaded shank thereupon screwing the same into the bore 14 of the swab head 12. The flexible swab elements 17 will thus be firmly gripped or clamped intermediate the end of the swab head 12 and the keeper-member 15, so that the free portlons of the same may initially overhang and envelope the sides of said swab head 12.
In utilizing the swab, in the simple form thereof above described, the same is inserted in one end. of the tubular or cylindrical member, the interior of which is desired to be scoured, (indicated at 19 by dotted lines 66 in' Figures 1 and2), and by means of a both metallic cross threads pushing stroke of the handle member 13, is
advanced or propelled therethrough. When :swab elements 17 are backed. As thus compacted the flexible swab elements will provide a relatively resilient mass calculated to conform to and frictionally en age the interior wall surfaces of the mem er 19, while at the same time the myriad of metallic projections, which the metallic fabric comprising said flexible swab elements provides, will exert a highly efficient abrasive scourmg member 19, which will quickly and easily remove therefrom encrusted or otherwise adhering dirt or soil, whereby the said surfaces are adequately cleaned. As the swab is advanced beyond the-end of the member 19, its motion is reversed by means of a pulling stroke of the handle member 13, whereby the flexible swab elements 4 17 are engaged by the far end of the member-19 and are reversed, (as shown in Figure 2), being thereby folded back to envelop the keeper member 15, and consequently are'supported for scouring eflect by the latter on the retroactive stroke of the swab device thus initiated.
I have found it desirable in some cases to cover the swab head with an abrasive covering. To this end I provide the swab head 12 with an enveloping jacket or cover 20. made of a metallic abrasive fabric, which maybein kind similar to any of the specific forms of fabric utilized for the flexible swab members 17 as above described. This jacket or cover 20 may consist of one or more layers of metallic abrasive fabric disposed to encircle the swab head. 12 and secured thereto ateach end by any practical form of fastening means, such as the staples 21, (see Figures 5 and 8 Thecovering thus provided may be furt er reenforced against other displacement by metallic stitc either or both longitudinal rows 22 an transverse rows 23. This covering or jacket 20 serves to provide several a vantages; first, it provides a more or less resilient abrasive surface in connection with the rigid swab head, which permits the latter to be utilized, with the flexible swab elements detached,
action upon the said surfaces of the creeping or for-the purpose of preliminary cleanlng opface with which the latter elements ma engage to prevent undue pulling strains t ereon, while at the same time providing an added resilient cushionbacking for the flexible swab elements, tending to increase the yieldable pressure of the same against the Interior sides of the member 19 when the device is passed therethrough.
Referring now to Figures 7 to 9 inclusive of the drawings, I have shown therein certain modifications of my novel swab device adapted to furnish the same in a fountain type, whereby steam, water or other fluid may be delivered therethrough during and in aid of the scouring and cleansing effects exerted thereby. In this form my novel swab device comprises a rigid substantially cylindrical swab head 12' which is provided with a tubular handle member 13', the pas-.
sage 24 of which provides a conduit for-conveying a suitable fluid to the swab head 12'.
In this case the tubular handle member 13'..
may be extended throughout the length of the swab head 12', and its outer end maybe internally threaded to receive the shank 16 of the keeper member-15. The body of the swab head 12' is provided with a plurality of radial discharge ducts .25 which respectivel match lateral discharge openings 26 provlded in the walls of said tubular handle member 13, as shown more particularly in Figure 8. In this form of swa provide the swab head 12' with the cover or acket 20, or it ma be omitted as desired. Ihe flexible swab e ements 17 areprovided and separably attached to the free end of the swab head 12 by-means of the kee er member 15 in the manner already a ove de scribed. As will. be understood, when making use of this fountain type of swab device, steam, water or other desired form of fluid ma be introduced through the passage 24, an thence discharged through the lateral discharge openings 26 and ducts 25, to flow through the interstices of the covering or jacket 20, and through the interstices o the enveloping folds of said flexible swab elements 17, as thelatter are passed back and forth through the member 19, thereby adding to the abrasive scouring effects, the cleansing efiects of the supplled fluid. As will be evident from an inspection of Figure 9, the keeper member may also be constructed to provide, if desired, fluid discharge assages in communication with fluid deivery conduit 24 of the handle, member. 13'.
In such case I provide a keeper member body 15' having an externally threaded shank 16' axially imbedded therein so as to project from one end thereof. Said shank 16' is provided with a lon 'tudinal passage 27 to communicate with t econduit 24 of the handle 'member 13'. The bod of the keeper member 15' is provided wit a plurality of radial discharge ducts 28 which respectively match lateral discharge ope 29 provided in the walls of the tubular v ank16'1 By this modified form of keeper member 15 the device I may steam, water or other desired fluid may be discharged from the keeper member as well as from the swab head.
I am aware that some changes may. be made in the arrangements and combinations of the several devices and parts of my novel swab, as well as in the retails 'of the construction thereof, and I therefore reserve the right to such constructions as do not depart from the scope of this invention as set forth in the foregoing specification, and as defined metallic fabric material detachably mounted intermediate said head member and keeper member andretained insuch relation by the latter, the free ends of said flexible swab means being of such length as to be adapted to fold down and about said head member so as to be backed by the same inone operative position but also adapted to be flexed.
away from said head to fold upwardly and about said keeper member so as. to be backed by the latter in another operative position.
