E CLEANING SNAKE AND OPERATING HANDLE THEREFOR Filed Jan. 20, 1947 Patented Aug. 16, 1949 UNITED STATES i twins 1 BIBE GLE-ANING-SNAKE AND: OPERATING HANDLE THEREFOR Frank-E. Flinn, Miami, Fla. ---"App1i,cati on-Janua ryr20, 1947, Serial Noa72ai l2t5 4 Claims. (01. 15-10430) This invention relates to novel formsof probing rodsor snakes lusedby plumbers, electricians, telegraph and telephone. linemen,.and others for passing'throughpipes or tubes to .clearfthem of obstructions, loosen congested matter therein, or to guide a "flexible wire. or line therethrough.
The use ofJsnakeshas-often been accompanied by extreme di'fficultyrin pushing or pullingthem through the pipe .orftube becauseof excessive friction and poor, grippingmeans. Gripping with the handle woul'dprovidevvery little gripping pressure, causing the hands to' burnQfron friction or slipping over the snake. Whenfgrippin the snake with pliers, the snake would often bend and .become kinkedmaking. it .useless. for the. purpose it was intended.
The object of the present invention is not only to eliminatethe above difiicultiesgbutfurther to provide simultaneouslyrmeans for. indicatingthe distance between various'poi'nts'in the pipe or tube in which the..novel snake is used, by pro-v viding the snake strip with a sei'iesof beads equally spaced at known intervals and having a simple, easily detachable gripping means for cooperation withthebeaded portions of the snake to prevent slipping andreduce'the tendency to bend or kinkthefsnake. I
.A further-object.is toim'ake a novel form of snake and gripping means therefor, which are simple but effective to reduce friction inwthe pipe or-tube, as well asprovide measuring means to indicate the distance toan obstructiom-or the length of. the pipe ortube, and to preventslipping of the gripping means.
A further object is-to providea non-slipping gripping block for a beaded snake having a'slot for said snake anda socket at one end in the bottomof said slot foralbeadto enter and lock the block against slipping along said snake.
A further object is to construct a gripping block for a snake strip having beads formed at intervals thereon, which will readily slip over an unbeaded portion andstoponsaid bead to form anon-slipping ripwhereby'to push said snake axially with little tendency to bend or kink it. Y
Other and morespecific objects-of the present invention willappearin-the following detailed description of oneiorm of device constructed in accordance withthe'invention, having reference to the accompanying drawing-wherein:

Figure '5is an end view oftlie block as seen from above'inFigures 1, 2,-Jo'r'3.
Figures 6 and 7 are sectional views of the block taken on .the'linesii fi er Figure '4 and .of

Figure 9 isa cross-sectional vi'ewof a, preferred form of. snake bodyrportion. M
Referring now to the drawings, the snake 1 has itsbo'dy portion cinch-circular contourpreferably bing g'oblong in crossa's'ection with parallel .side "faces-sand has beads 2 formed thereon at intervals which maybe or apredetermine'dlength, a'daptablei'or insertion in apipe or tube for therpurposfes outlined above,
The gripping block 3 may be made of metal or other suitable material an'tIis :large enough to provide a goddgfipby'haJnd. :It hasa slot "4 extending fromlone fofits narrower sides "5 to approximately itslrniddle. "'Here one-end of'the slot is enlarged resume bead "to freely pass through'this end, the; rest or the slot bein just big enough 'to'allowfan unbeaded portion of the snake strip to slip through it e'dgew'ise. This ens largeduportion of "the jslotisfshownat 6 and extends approkimateiyto theicenter'ofthe block. Withsuch construction, it willbere'adilyseen, as shown inFi gure 8; thatthesnake when passed through a "pipe er "tube" will touch the sides I of said pipeor'tube onlyatthe bead points, thus reducing the friction which anordinary snake strip without thebeads would normally produce. This means aconsiderablereduction ofefiort required to push orpull a snake'ithrough ariy1particular pipe or'tubeq v :In Figure 8, the snake l: is beingpushedthrough the pipe 1 by'rmeansof the block 3, which "has been *slipped onto thestripabove the bead 2', with the enlarged ,:endportion .of the -s10t 6 extending downwardlygand then moved down so that'bead Wenteredsaidenlarged portion and wasstopped by thevupper ,eiidthereof where it na rows tothethi-cknessof th snake strip. .Thus,
the block will not slip off the strip, nor any further along the strip when pushed forwardly.
When the snake is pushed down by means of the gripping block as far as possible, the block is backed off the bead by movin it upwardly along the snake strip and then slipped off the strip. A new hold is established at another bead higher up on the snakestrip in the same manner, and the snake is pushed further into the pipe, etc.
If it were desired to pull the snake out of pipe 1, the block 3 would be reversed so that the enlarged portion 6 would extend upwardly and the block would be slipped onto the strip below one of the beads and then moved upwardly over the bead to provide a non-slip contact therewith in revers direction. The advantages of the assembly of the snake and its operator. are more or less obvious. Since the snake body is oblong in cross-section, and the width of the operator kerf 4 is greater than the thickness of the snake body but less than the width of such body, the two can be assembled only by positioning the operator between successive snake beads and providing relative movement of operator and snake edgewise of the snake to place the snake in the axial zone of the operator. Since the kerf enlargement is limited to the axial zone of the operator and extends from an intermediate point in the zone lengthto an end of the operator, the remainder of the kerf in the axial zone maintains the kerf width condition which prevents rotation of the snake within the operator. Hence,
thus providing a snake completely, serviceable under these conditions.
In this connection, the presence of the bead zones at regular distances and comparatively short distancesa foot, for example-is of definite advantage, due to the fact that the user may employ the operator close to the entrance of the drain on which he is operating, if desired. With the beads spaced a foot apart, the advance is by steps of approximately such length with the operator shifted between steps. Hence, the length of snake exposed between the drain and the operator is comparatively short and thus less likely to bend materially or buckle under turning or pushing pressures. Due to this manner of using 7 the assembly, it is apparent that both snake and any positioning of the operator on the snake I whether in positionrelative to a bead point or between adjacent bead points-so connects the operator andsnake that any movement ofthe operator rotatively will provide 2. corresponding movement of the snake.
The operator must be initially positioned by application to the snake between adjacent beadsa beaded zone cannot enter the kerf through the open side-and then be shifted longitudinally of the snake body to place the bead zone within the operator; body has been moved to the bottom of the kerfthe axial zone of the operator which carries the enlarged portion indicated at '6 which extends from an end of the operator to an intermediate point. When the operator has been moved lengthwise in this zone sufiicient to bring the bead into contact with the bottom of the enlargement 6, the assembly is in such condition that not only can the snake be rotated by rotating the operator, but can be advanced--by.pushing on the trailing end ,of the operator-or be moved backward-by drawinglthe operator in the direction or its leadin end. Hence, the operator can be used, at will, for movement of the snake in. either direction and at the same time enable the rotative movement of the snake to be had whenever the operator is applied.
As is apparent, the assembly is designed for service more particularly under conditions where it can be readily manipulated by hand operation of the operator, although not limited to such conditions since the operator is of such shape and dimensions as will enable the application of a wrench thereto to aid'in providing rotating movement. The operator is fairly small and readily received within the hand or fingers for manipulation in positioning and in service; the snake body cross-section is generally approximately 0.125" in width and 0.0625" in thickness,
this can be done only when the snake operator, while separable, are specifically dimensioned for service in combination, since, in service, the two elements are completely and directly complemental, with both required for the desired efiicient service.
The construction is very simple, the device is easily made, and its operation is quick and positive, eliminating slipping of the gripping means and reducin any tendency to bend or kink the snake. Also, if the beads are formed at equal intervals of a foot, a yard, or any other predetermined distance, a count of the number of beads between points in the pipe or tube will indicate the distance advanced, so that the beads not only serve as a means for reducing the friction between the snake and the pipe or tube, but also provide means for indicating distances in the pipe or tube.
