NATIONAL WATER. M.LIN CLEANING COMPANY, OF NEW YORK, Y., A CORPORA' TION' 0F MAINE.

DEVICE F03 PASSING-CABLES rnnouen WATER-PIPES.

I Be it known that I, HUGH A. GREENAN, a citizen ofthe United States of America, and

' a resident of New York, in the county and State of New York, have invented acertain new'and useful Improvement in Devices for Passing Cables Through Water-Pipes, ofwhich the followin is a specification. This invention re ates to pipe cleaning devices and more particularly to the means for carrying the. cables and ropes to which such pipe'cleaning devices are attached, through the pipes to be cleaned as a preliminary to The'- object of the device is to carry the v rope or cable through the water pipe'bythe use of the pressure of the water passing through the pipe, and thus save time in the preliminary operation.

The device is made highly elastic and made to fit closely in'the pipe to be'cleaned in which it is propelled by the pressure of the water acting on one side of it, while carrying a flexible wire attached to the cable,

or, in the larger sizes used, in'larger pipes,

carrying the cable itself before the cleaning device is introduced into the cable.

The device is economical in construction and simple in operation as will, 'beshown,

refere'nce being had to the specification and.

the drawings in which Figure l is a sideview of the device. Fig

2 is a lon 'tudinal sectional View.

- In the evice shown, acup or bell-shaped; 5, is constructed of rubber or other; flexible material, which will permitpfflth'e body reductionor the increase of the diameter. its rear end so that it may readily be introduced into a pipe of slightly less diameter.

than the bell or, so that when insertedintoa.

larger pipe the fluid pressure..at ;its rear tends to expand it, so; that the diameter'becomes increased. I .1 The bell 5 is attached at its up or or for ward end to a head 6 made of woo .or hollow,

metal in order to lighten the device, and" through the whole runs an axis, made in two parts. The rear part 7 has an eye-8 and is provided with a collar or pin 9. The forward part 10 ofthe axis is threaded and carries a binding nut 11 and a lock nut 12. To, the lock nut'f12' is attached a'spindle 13, which has the shape of a pointed cage, so that its forward end may move clear of the bottcmor sides-of the pipe and avoid obstructions in the pipe. This spindle serves ification of Lett r ,P n Patented Sept. 21, 1909, Application filed February 2a, 1906. Seria1'No.302,431. I I

as'a guide during-the passage of'tl'ie device through a pipe.

In order to give more'solidity to the hell 5 and to prevent it. from becoming inverted, light flat retractilespringsi, are provided and areattached to'thebell by means of bolts 15, and their forward ends are fastened to the head ofthe hell by screws or other suitable means.

While the device is Shown as carrying a wire .16, it maybe coupled direct to a cable orrope carryingya cleaning device, the latter course followed only when the device and the pipe through which it ispassed are of; sufiiciently large diameter.

The whole device is constructed with a view of roducinga light structure, readily moved orw-ard by the water pressure hehind 1t and protected against tearing by the projections caused byjaccretions and deposits inthe pipes to be cleaned.

Thespindle' 13 may beinade of a hollow sheet of metal, or of wood without departin from the in'yention.

at I 'claim as new is:

11. In a. device of the-characterdescribed,

the combination of a flexible cup, a head attached tothe pointed end of said cup and placed in front thereof and retractile' springs attached to the head and cup and adapted to prevent inversion of the latter. I 2. In a device of the characterdescribed, 'the combination of a flexiblemip, a head at:

tachedto the pointed end of said cup and placed in front thereof, retractile s rings at tached to the said head and cup an adapted to prevent inversion .of. the latter, and a pointed guiding device attached to the head.

' 3. In a device of the character described, a

cup, ahead attached in front thereof and, springs attached to the head and adapted to; 'pre'vent inversion of-said cup.

4. Ina device of the character described, a means attached to the head adapted to prcup, a head attached in front thereof, springs vent inversion of said cup. 10 one end of each of which is attached to sald Signed at New York thls 20th day of Feb. head, the other end restin in contact with 1906.
