sTnAiNING-PLU'G Specification of Letters Patent.
Patented Dec. 24, 1907.
Application filed february 21,-1907. Serial No. 358.623.
'the follmving is a speciiication, reference being had therein to the accompanying drawing.
This invention relates to 'a strainingl plug. l
l i l andparticularly to a forni applicable to a i pipe section used inliquid pumpingby` iii-- sei-tion in an aperture therein.
The invention has for an object to provide s read laterally to reduce the width of said sits to the necessary degree oftncncss for the straining action.
A further object ol' the invention is to provide a forni of straining plug comprising a slits in .the 'head thereof together with a order to retain them in Contact and io prowhich the slits are broken Fig. 13 is a section ol a blank; Fig. 14 is a sectional perspective of the dieand blank swaged thereon, and Fig. 1.5 is a section of a plurality of disk plugs disposed Within a iiiii.
Like numerals refer to like parts in the several views of the drawing..
Referring to Fig. 1, the numeral l designates a cap plug the head of which is provided with a series of parallel straining slits 2 extending entirely across the same and se arated bythe bars 3 each of which is sivage or otherwise spread laterally as at 4; so as to rev duce the width of the slit at the outer face of a plug body having slits separated by inter- I vening bars one lface of each of .vhich is Q the plug thereby securing the necessary tineness lor the straining action with a free clearance space directly at the rear of'this face which will allow sand or other matter g having a tendency to clog the strainer to be forced through the slits under pressure of the lluid, or by the pumping action and not be series of disks each having parallel straining l held between the bars thereby closing the slits and preventing a full llow. strengthening rim surrounding the disk in p' vide tho necessary strength of material for forcing thepliig into the pipe section and prevent any distortion of the slits therein during such action as it is desirable to forni the disks of relatively light bendable material in order to 'facilitate the cutting oi' the slits in the disk and the subsequent su'aging or closing thereof. p
Other and further objects and advantages of the inventioii.\vill be hereinafter' fully set forth and the novel features thereof defined by the ap )ended claims. ,ln the drawings" Figure 1 is a perspective of a cap plug embodying the invention; Fig. 2 is a siin'ilar view of this plug with 'the protecting rim; Fig. i; is a vertical section through Fig. 2; Fig. -1 is a similar view showinga modified forni of ring; Fig. 5 is a perspective of a cap plugliuving the slits thereof extended only partially across the head; Fig. 6 is a cross section on the line .6--G, Fig. 5; Fig. 7 is a vertical section through a further modification; Fig. 8 is a similar view showing a further modification in which the head ofthe cap is next the interiorof the ipe; Fig. 9 is a perspective of a disk plug;
Mig. 10'is a section on the line 10-1(), Fig. 9
Fig. 1 t is a perspective showing a plug slitted in opposite directions; Fig. 12 is a sectional ln Figs. 2 and 3 the forni of plug shown in Fig. 1 is ,')revided with the strengthening rini 5 having an inwardly extending iange 6 against. which the base of the plug,r will seat.
rlil'iis liange provides the necessary rigidity to the plug to pernnt its insertion in an aperture in the pipeunder pressure Without distorting o'rdestroying the proper relation of the slits with each other or the diameter established at the point 4 thereof.
in Fig. -l thc plug shown in Fig. 1 is supplied with a niodilied forni of ring 7 which is provided with the shoulder S to' seat in the pipe aperture.
ln Fig. 5 a cap plug is shown at 9, the
head of which provided with the flange 10 io sent in the .pipe aperture, as shown in F ig. (i, and thc slits 11 are only extended for a portion of the Width of the head,'.while the intervening` bars 12 are each spread upon their outer face, as at 13 to reduce the width of said slits at that point. In Fig.. 7 a similar forni of plug 14 is shown in iivliicli the flange 1t) is omit-ted, and the bars 1 5 suitably spread lto control the diametrof the slits extending betweentlie saine. Y v 'Y ln the modification @Showirin Fig. 8, the spreading action of the barsl. of the-,cap
plug 17 there shown is upon'the inner face,l
and the bars may be formed Withzgrooves'or depressions b v which the spreadingr will be facilitated. ln this forni-thelwidere.ii.clear 'liti ance space of the slits is next the interior `of the pipe 19 so as to facilitate cleaning there-- of when necessary by a Wire brush or swab.`
The modifications shown in Figs. 9 and l() illustrate a disk plug 20 provided with a series of parallel slits 21 and the separating Ybars 22 each 'of which is spread at its face 23 to govern the diameter of the slits as before described.
ln Fig. 11 the plug 24 is provided with two series of slits 25 and 26 disposed at an angle to each other, the faces of the intervening bars 27 on the outer face being spread or swaged to secure the proper dimension of slit.
Fig. 12 illustrates a disk plug 28 through which the slits 29 are punched or broken, the projecting edges 30 thereof being closed by v pressure to determine the proper dimension Stil .and are thus held for insertion in a pipe section. When in such position theslits of the dibsk are preferably disposed in alinement.
It will be observed that in all of the applications of this invention the plug is adapted to be made with slits or slots of a Width greater than that intended for use, and by the spreading of .the intervening bars the slits are reducedI to the proper width for the purpose desired. This is of, particular im-y portance as in the practical man acture of such 'a plug it 1s diflicult to cutfthe slit of the required narrowness and accuracy, and the: invention permits stamping or punching off.;
the slits, and the subsequent finishing action A by the spreading of the bars to reduce the width of the slits to the required narrowness and'fineness at the entrance point of the Inaterial leaving the slits with a widened discharge portion extending in the direction of the iow therethrough, which eHect a much 'more desirable clearance andiniore `uniform :accuracy of slit than can otherwisebe secured. ",With the use of the strengthening rim the disks can be formed of the necessary character and weight of material to facilitate this production by a punching or stamping operation and one or a number of such disks'mayV be held Within said rim and are thus supported or strengthened to permit their insertion into a pipe under pressure. The invention therefore presents a simple `and elhcient means for producing .a 'straining plug having vthe proper diameter to prevent the entrance of extraneous material while effecting a free flow of the liquid therethrough.
Having now described my invention and set forth its merits, what l claim and desire to secureby Letters Patent is z lfA straining plug having a body pro-l vided with slitsv separated by intervening bars one face of yeach of which is spread laterally to form a pointed overhanging edge deilected from the"plane of the side Wall of the bar andapproaching a similar ed e upon a paralllfbar to reduce the width o said slits between/the apices of the opposite edges.
2. AIna Well strainer, a cap plug comprising a plurality of disks each having a body provided with slits separated by intervening bars one face of each of which is spread laterally to form a pointed overhan ing edge deflected from the plane of the si( e wall of the bar and approaching a similar edge upon a parallel bary to reduce the width of said slits Abetween the apices of the opposite edges.
3. A straining plug comprising a plurality of slitted disks in contact with each other, and a strengthening rim surrounding said disks.
4.' A straining plug comprising a plurality of slitted disks disposed with their. slits in alinement, and a strengthening rim surrounding said disks and having an inwardlyY extending flange to engage the face of one thereof.
In testimony whereof, l affix my signature in presence of two witnesses. JOSEPH H. MCEVOY;
