NOV. 27, T HADE GUIDE FOR PIPE CLEANING DEVICE S Filed July 1'7, 1955 JOHN 57/005 INVENTOR BY g 5% A TTORNE Y Patented Nov. 27, 1934 1 OFFICE GUIDE FOR PIPE CLEANING DEVICES John '1. Shade, Altoona, Pa. Application July 17, 1933, Serial No. 680,861
This invention relates to devices for cleaning drain pipes and has for its primary object improved means for holding the cleaning rod, as well as directing the same when being used to open drain or sewer pipes.
Another object of this invention, is to provid improved means for keeping the cleaning rod from buckling when the same is being pushed into the drain pipe.
A further object of this device, is to provide positive means for obtaining definite stroke lengths when the cleaning rod is being pushed into the pipe or drain that is being opened.
With these and other objects in view, which will become more readily apparent as the nature of the invention is more fully understood, the same consists in the novel construction, combination and arrangement of parts as will be hereinafter pointed out, illustrated, and claimed.
It will be quite readily understood by those skilled in the art to which this invention belongs that the same is susceptible to some structural change or modification without departing from the spirit or scope of the invention, but a preferred and practical embodiment of the invention is shown in the accompanying drawing in which:--
Fig. 1 shows a plan view of my improved pipe cleaning rod guide.
Fig. 2 shows a longitudinal sectional view taken of the device shown in Fig. 1, and shows the cleaning rod pushed through the rod guide at the end of the stroke. This view also illustrates the manner in which I construct the rod guides, such that one guide readily slides within the other.
Fig. 3 shows my pipe cleaning device applied to a pipe and clearly illustrates how the cleaning rod is directed into the pipe in order to prevent the same from buckling or starting in a direction contrary to that intended.
Fig. 4 shows a longitudinal view of the inner guide, with the cleaning rod positioned therein. This view also illustrates the rod clamp used to hold the rod secure in the inner rod guide while the cleaning rod is being pushed into the pipe to be cleaned.
Fig. 4 also illustrates a short length of coiled wire which can be as readily used in this type of guide as a ribbon or a round rod.
Similar reference numerals refer to similar parts throughout the several figures of the drawmg.
In carrying out this invention, I provide an outer guide casing or pipe designated by the numeral 10. The outer end 11 of this casing is suitably bent to direct the cleaning rod 12 into the pipe to be cleaned.
The casing 10 is further provided with a twodiameter fitting 13, the larger diameter or bell mouth of which is internally threaded to receive the threaded end 14 of the casing 10. The smaller diameter of the fitting 13 is not, but acts as a guide for the inner guide pipe 15 as shown in Fig. 2 of thedrawing.
Further attention is now directed toward Fig. 2 which shows the various elements in their respective operative position.
The inner guide pipe 15 is provided with a collar 16 at its inner end while the outer end 17 is provided with a holding handle 18, to which is attached a rod clamp 19, which clamp is made operative through a thumb-screw or similar device 20. The handle also acts as a stop when the inner pipe 15 is pushed into the outer guide pipe 10, as clearly illustrated in Fig. 2 of the drawing.
Attention is further called to Fig. 3, which shows the outer guide casing 10 entering a drain pipe, while the cleaning rod 12 is being pushed through the pipe 22, which is shown being cleaned.
The operation of this improved pipecleaning device may be described as follows:
The end of the cleaning rod 12 is placed in the handle opening, and the rod pushed through the inner casing and also through the outer casing 10. The end 11 of the'outer casing is then placed into the pipe end as shown in Fig. 3, the inner pipe 15 is drawn out of the outer pipe until the collar 16 impinges upon the inner surface of the fitting 13. The thumb-screw 20 is .then rotated and the clamp 19 clamps the rod in the handle 18. The inner tube is then pushed into the outer tube carrying the rod 12 forward into the pipe 22, and this forward motion is continued until the end of the handle 18 strikes the fitting 13, after which the thumb-screw is loosened, permitting the clamp to rise and the pipe 15 is retracted until the collar 16 engages the fitting 13, after which the clamp is again drawn down and the next stroke is then made pushing the rod 12 forward into the pipe to be opened.
Having thus described my invention, what I claim and desire to be secured by Letters Patent 1s:
A device of the character described comprising an elongated casing of reduced diameter at its outer end to provide a shoulder and a guide sleeve, a tube extending slidably through said guide sleeve into the casing and provided at its carried by the handle at the exterior thereof,
a medial portion disposed at substantially right angles to said outer end portion and extending through the slot in said handle, and an inner end portion extending forwardly from said medial portion and disposed in the opening in said tube for clamping engagement with the rod to releasably secure the rod and tube together, and a screw member threaded in the handle for cooperation with the said inner end portion of said leaf member toreleasably force the same-into gripping engagement with the rod.
