Gimme. (C1. ls -1 04.30)

This invention relates "to plumbers snakes and the like, that is, those flexible shafts, wiresrim hons, bands, etc., that are employed by plumbers or laymen for clearing their kitchen and bath room drains. However, this same device may be used for drilling, tap-ping, boring, etc., by providing the proper tools at the end of the flexible shaft. The device of this invention is so arran ed and constructed that inexperienced persons can easily and quickly-clear drains and the like of obst'ructi'ons by merely working a crank handle. The job can be done without soiling the clothes in that no part of the shake need come into contact with the person using same in that a housing is provided for the snake wherein it is kept in perfect order 'and r'eady at all times to bewiggled through any drain pipe or the like. By providing a wiper device where the flexible shaftenters the device, the shaft wire or cable can be kept clean so as not to carry dirt and odors into its housing.

One of the principal objects of this invention is to present a new and novel ipe opening and/or cleaning device that is easy to operate and dependable to do the job, a device that is small or size, simple and sturdy in construction, and which "is economical to make and manufacture.

Another object is to provide a plumbers snake operating device that is safe to use, that is positive in its operation, and which can he kept a reasonable sanitary condition without any ell-illc ulty whatever.

Still another object :is to provide a boring device thatcan be either hand or-lnacliineoperatile and which rotates afleXib-le or serni-flexible shalt, tape or'wir'e means, or a series of linked elongated members, which efficiently and positively can easily work its Way through any type or kind of tubing, casings, pipes, or bores.

And still another object is to present -''a housed plumbers snake element that is provided with 'a lead brush and/or scraper, but which element when employed alone is effective in scraping the inner surfaces of bores and the like as it is retated and forced therethrough. Y

Other objects, advantages and features of my invention will appear "from the accompanying drawings, the subjoined detailed description, the preamble of these specifications-and the appended claims.

Applicant is about to illustrate and'describe one. of the forms of his invention in order to teach one how to make and use the same, but it .is :to :be understood that, the drawings and description thereof. are not to limit the invention in any 2 sense whatsoever, except as limited by the appended claims.

In the drawings:

Fig. 6 is a sectional view of the device shown in Fig. 5, and taken substantially along line =li6 thereof,

Fig. '7 is an enlarged detailed part, partly in el'evational view and partly in sectional view, which is employed "in both forms of the invent-ion.

The first illustrated form of the invention, shows a wplu-mbers snake feeding device l in a kitchen sink 2 v'vl'rlch has 'a drain pipe 3 and entry box 4 thereto. The device comprises an annular housing wall '5 with an end covering or disc-like wall 6 at one side and a similar wall I at the other side; these end walls consisting of sheet metal having inwardly turned flanges 8 which may be screwed or soldered to the annular wall dwhich they overlap. At the bottom'o'f the housing, there is a pedestal like supporting-member 9 that may be fastened in any suitable manner to the annular wall as by soldering or welding the flange l0 the eof to the bottom :of the annular wall. The member 9 is preferably a suction cup, that is, an inverted rubber cu that can be 'ma'de removably tight to the outer "top surface of the sink when desired. -At the top of the housing, there is a handle H having its legs soldered o'r w'e'lded'to the top o f-the-annuua-r wall so that the device can beeas'ily carried and also held when the crank of the device is being worked.

Concentric 'with'the device is a shaft l2 which has its ends journall-e'd in the wall bearings T3 and I4, and keyed to one end of the shaft is a crank handle 15, and near this end of the shaft, but within the housing, there is keyed thereto a large "bevelled gear Hi, as-sh'own. 'The gear 'l'tis in mesh with a bevelled pinion gear I! which is journalled in the wall bearing I8, but this pinion gear has a stem or coupling element I9 extending therefrom which is integral therewith and which is provided with a chamber or bore 20 at the distal end thereof to receive one end of a flexible snake, shaft or rod 2|. This snake end may be sweated into the chamber with solder, or one or more small set screws may be employed in an obvious manner.

The stem I9 of the pinion gear may alternatively be fixed to the snake as shown in Fig. 4 of the drawings. In this figure, the stem of the pinion gear is indicated by the numeral l9 and the expanded convolutes of the snake are indi-- cated by the numeral 2|. When the snake end is fixed to the stem as shown in this figure, the convolutes 2! may be soldered or welded to the stem I9. In any event, the snake must be firmly fixed to the pinion-gear-stem so that when the gear is rotated, the snake 2| is rotated and thus the snake can easily work or worm its way through bores of most any kind and of most any length.

Within the chamber of the housing I, there is a spirally arranged sheet of metal 22 which is positioned around the shaft IE, but the inner edges of the sheet 22 need not be close to the shaft but may be materially spaced therefrom so as to not interfere with the shafts rotation and also to provide air circulating spaces which are in direct communication with perforations in the sides of the housing for the purpose of allowing the snake to readily dry after being used in a wet drain pipe. The outer edges of the spiral sheet may be soldered or fixed to the inner surfaces of the housing annular wall in any suitable manner. By this construction, a continuous chamber is provided to receive the convolutes of the snake when the snake is not in use, or the portions of the snake which are not in immediate use when. the device is employed for cleaning or opening drains.

The snake is worked through an egress-ingress socket or feeding unit 23, which unit is shown in detail in Fig. 7 of the drawings. The unit has a block 24 provided with an extending fiange 25 which is welded to the housing wall 5, or riveted thereto as shown. The block has a bore 26 which is rifled to conform with the outer surfaces of the snake, which snake in this particular case consists of a large number of convolutes of rounded metal juxtaposed to one another to form a uniform flexible snake which has spring stiffness and which is continuous from end to end thereof. The working end of the snake may have its convolutes expanded and the very end of which may be sharpened, as at 2 I", to provide a good working point to aid the snake making its way through a bore and also for aiding the snake end to cut into obstructions within the bore. It

should now be very obvious, that as the pinion gear rotates the snake, the snake is fed, in a positive manner, forward or vice versa, through the feeder element 24 where the snake is forced to rotate with positive strength by the threadlike inner formation of the block at 26. A lower end of the block 24 is protruded and sized to snugly receive the top end of a flexible duct or pipe 21, which pipe may be a short length of common garden hose. The hose may be held to the protrusion by any suitable clamping means, such as, for instance, the garden hose type of metal clamp indicated at 28. The purpose of this hose is to guide the snake from the outlet or block 24 4 to the top of the drain opening which leads to the clogged pipe or duct.

The form of the invention shown in Figs. 5 and 6 is very much like the first one just explained. This form has a rectangular-box-like housing 30 which is supported by the two legs 3i and 32, each of which is provided with suction-cup-like feet 33. The leg 32 is provided with a leg guide and a finger adjustable screw 34 so that this leg can be shortened or lengthened and thus allow the housing to be tilted for a special use when necessary.

The form shown in Figs. 5 and 6 is otherwise the same as the first form, that is, it has the same crank handle means I5 which works directlyupon gear 35 (somewhat smaller than gear 55) which is in mesh with the pinion gear IT. The pinion gear in turn works the snake 2| which is connected thereto, the distal end of the snake working out of the housing via the feeder block 23. Instead of this form having the spirally arranged single plate within the housing for maintaining the snake in good order, a series of staggered plates 36 and 31 are employed, the top plates being centered in the spaces between the lower plates 3'? and illustrated clearly in Fig. 5. A handle 38 is fixed to the top of the housing for carrying the device from place to place and also for steadying the device when in use. Obviously, any suitable tool or brush element may be fixed to the distal end of the snake for use in performing the work to clear the drain, or to bore and chip in most any tube, pipe, or other inaccessible place.

It is, of course, understood that various changes and modifications may be made in the details of form, style, design and construction of the whole or any part of the specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the limitations clearly expressed in the following claims.
