PIPE CLEANING MACHINE Filed Sept. 26, 1958 INVENTOR.
Robert G. Hum
54 .53 5 Afforneys fid Stan-3s Patent a, A
2,955,307 PIPE CLEANING MACHINE .FiledSept. 26,1958, Ser. No. 763,578 2 Claims. (11. -1043 This invention has to do generally with tools used by plumbers for cleaning and removing obstructions from waste pipes, particularly pipe cleaning tools utilizing an elongated member in the form of acoiled spring of small diameter, known as a plumbers snake, which is advanced through the pipe and rotated, the snake carrying ;a tool of appropriate design at its forward end for engaging and .dislodging or cutting the obstruction in the pipe.
Spring type snakes are ordinarily stored or housed in a drum or container having a conoidal wall through .the axis of which the snake is fed and retracted axially of itself as the container is rotated to cause rotation of the snake. Normally the snake is advanced manually although some tools have power-driven means for advancing the snake. So far as I know, presently used tools which embody power-driven means for advancing the snake are either expensive, cumbersome, heavy, or have a relatively low safety factor, being prone to cause breakage of the snake since either no means or inadequate means is provided for releasing the driving thrust from the snake in the event the snake him an obstruction which suddenly stops its axial movement.
An object of the invention is to provide a novel pipe I cleaning machine adapted to store and house a coil spring type of snake and to simultaneously rotate the snake and feed or retract it at various speeds at the will of and under full control of the operator.
Another object is to provide a pipe cleaning machine of the type indicated embodying a novel snake drive means adapted to impart axi-al movement to the snake which is so constructed that no damage can result to the snake in the event of the sudden stoppage of its axial movement.
A further object is to provide novel power-actuated means for releasably engaging the snake to enable the operator to manipulate the snake by hand or to employ power drive therefor.
Still another object is to provide a pipe cleaning tool which is easy-to operate in that it requires no particular skill, and is of simple, ruggedconstruction.
These and other objects will be apparent from the drawings and the following description. Referring to the drawings:
Fig. 1 is a side elevational view of a pipe cleaning tool embodying the invention;
Fig. 2 is a front elevational view of the tool of Fig. 1.
Fig. 3 is a fragmentary sectional view on line 3-3 of Fig. 2, but on a larger scale;
Fig. 4 is a sectional view on line 4-4 of Fig. 3; and
Fig. 5 is an enlarged sectional view on line 55 of Fig. 3.
More particularly describing the invention, 11 generally designates a frame shown made of tubular stock which is bentto form a pair of ground-engaging base sections 12, a pair of forward,- converging sections 14 which are rearwardly inclined, and a pair of rear sections 15 which are joined at their upper ends by a bridging section 16. A handle 17 is mounted on section 16. The
2,955,307 Patented oct. 11', teen frame supports a pair of journals, designated 20 and .21 respectively which rotatably support .a storage .01 container 22 in which the plum'bers snake is coiled in .a manner well known 'in the art. A portion .of the snake is shown projecting axially from the drum and is designated by the letter S. A motor is mounted upon a bracket 25 supported on a crosspiece 26. The motor is adapted to rotate the drum by .means of a belt .27 passing around the cylindrical portion .28 of the drum and a sheave 29 upon the motor shaft '30.
A shelf bracket 32 extends between the two frame sections 14 and supports the aforementioned journal 21. Also mounted on the bracket 32 is a frame member 34 which is secured by means of capscrews 35. 'Member 34 provides two upwardly extending platelike portions 36 and 37 which are spaced laterally and are generally .parallel. These provide a relatively large space 38 therebetween to accommodate a sheave 40 which is fixedly mounted on a tubular drive shaft 41 journaled in pot tions 36 and 37 of the frame 34. The outer end of the drive tube 41 supports a snake-engaging drive means designated generally by 44. This latter member is .simi: lar. to .a collet type chuck in that it includes a movable collar 45 having a cam face 46 v therein having tapered end faces 4 The member 47 is formed on its inner surface 50 with screw threads formed to mate with the outer surface of the snake S.
The collar 45 is adjustably carried upon a feed drive body 52 which is fixedly secured to the front end of the drive tube 41. Member 52 is counterbored at 53 to receive sleeve 47 and a retainer sleeve 54 therefor. The latter is slotted at its inner end at 54 to receive the cars 47 of sleeve 47. Collar 45 is slotted at 45' to accommodate a screw 56 which threads into member 52, and is used for tightening the device in either engaged or disengaged position.
In order to provide a safe, easily releasable drive connection between the motor 24 and the snake drive means 44, I provide a gear housing 60 having mating sections 61 and 62. Journaled in the housing are two meshing gears, designated 63 and 64 respectively. One of these is keyed to the shaft 30' of the motor and the other is keyed to a stub shaft 66 upon the outer end of which is fixed a sheave 67. A belt 68 is trained around the sheaves 40 and 67.
It will be apparent that the housing is mounted for pivotal movement about the axis of the motor shaft to vary the tightness of the belt 68. In order to control the position of the gear housing 60, I provide a link 70 which is pivotally mounted at the upper end, of the housing at 71 and pivotally mounted at its upper end upon a foot portion 73 of a vertically movable handle 74 which is carried in a guide tube 75.
In the operation of the device, the motor 24 (which should be a reversible electric motor with suitable controls therefor, the controls not having been shown) serves to rotate' drum 28 in which a portion of the snake S is coiled thereby serving to rotate thesnake about its axis on the axis of rotation of the drum 22. With the snake drive means 44 in disengaged position the snake may be advanced or retracted manually. However if the means 44 is moved to snake-engaging position, the snake can thenbe driven axially. If the belt 68 is loose and thus does not serve to rotate the means 44, the latter will act as a stationary nut and the snake, which is rotated by rotation of the drum 22, will thread itself axially either forwardly or rearwardly therethrough, depending upon the direction of rotation. In this connection, the inherent friction of the means 44 plus the Weight of the belt on the sheave 40 is normally suflicient to cause means 44 to remain substantially stationary. In order to advance or retract the snake at a faster rate it is only necessary to and a split sleeve 47 manipulate the handle 74 by pressing down thereupon to means 44. The gearing in the housing 60 ofcour-se serves to reverse the direction of rotation of the means 44 with respect to the drum 22 and snake S, thereby rendering the means 44 efiective to rapidly advance or retract the snake.
While I have shown a preferred form of my invention, I contemplate that various changes and modifications can be made therein without departing from the scope of the invention as indicated by the claims.
I claim:
1. In a pipe cleaning machine, a frame, a drum rotatably mounted on said frame and having an opening on its axis of rotation for axially passing a snake member,
a snake drive means mounted on said frame forwardly of said drum for rotation about the same axis as the 20 drum, a snake member comprising an elongated helically coiled spring adapted to be substantially housed in said drum, said snake member extending from the drumi through the opening therein and through said snake drive means, said snake drive means including a chuck device having jaws adapted releasably to threadedly engage with the snake member, a motor mounted on said frame beneath said drum and said snake drive means and having a shaft, a sheave fixed to the shaft of the motor, a drive belt around said sheave and around a peripheral portion of said drum for driving the drum, and disengageable drive means between said motor shaft and said snake drive means.
2. A pipe cleaning machine as set forth in claim 1 in which the disengageable drive means between said moto'r shaft and said snake drive means includes a sheave on said snake drive means, a gear housing, a pair of meshing gears journalled in the housing for rotation about parallel axes, one of said gears being fixed to the motor shaft, a sheave fixedly secured to the other gear, a belt loosely trained about the sheave on said gear and the sheave of the snake drive means, and means for adjusting the position of said gear case pivotally about the axis of said motor shaft to adjustably tighten said belt.
