F. w. GREEN 2,029,232


This invention relates to a flusher especially adapted for cleaning foreign matter from the cooling system of an internal combustion engine and has for the primary object the provision of 5 a device of the above stated character which may a be easily and quickly connected in the cooling system and to a pressure water system whereby the water may be caused to circulate through the cooling system in either direction for dislodging and carrying from said system any accumulated material or substance and also is capable of directing air under pressure along with the water through the cooling system when desired.

With these and other objects in view this invention consists in certain novel'features of construction; combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention,

reference is to be had to the following description and accompanying drawing, in which Figure 1 is a fragmentary plan view illustrating a motor vehicle with a flusher adapted thereto and constructed in accordance with my invention.

Figure 2 is a side elevation, partly in section, illustrating the flusher.

Figure 3 is a horizontal sectional view illustrating the control valve of the flusher and the difierent positions occupied thereby. I

, Figure 4 is an end elevation illustrating the water and air connection to the flusher.

Referring in detail to the drawing, the numeral i indicates a fragmentary portion 01 a motor vehicle, the engine being indicated by the character 2 and the radiator by the character 3. To adapt my invention to the engine and radiator, the upper hose connection to the radiator of the engine is removed and connected thereto are flexible hose 4 and 5, the hose 5 being connected to the radiator 3 while the hose 6 is connected to the outlet nipple of the water jacket of the engine.

The flusher consists of a casing 6 having a valve chamber 7 in which operates a valve element 8 between spaced stops 9 and Ill. The valve element is carried by a stem l l which extends outwardly of the casing 6 by way of a neck I2 having a packing nut or gland IS. The outer end of the stem is equipped with a handle l4 whereby a person can conveniently change the position of the valve element 8.

A water inlet nipple l5 communicates with the chamber 1 at one side of the casing 6 and directly opposite to the water inlet I5 is an outlet nipple l6. Nipples I1 and I8 are in communication with the chamber 7 and are located on opposite sides of :the nipple I5 and in close proximity thereto. The nipples i! and I8 are connected to hose fittings 20 by flexible hose 2| and the fittings 20 connect with the hose 5 and 6. A fitting 22 is provided for the nipple l5 for connecting a hose thereto which is in turn connected to a water pressure system. The nipple 5 I6 may have a drain hose 23 connected thereto, as shown in Figure 1. The casing 6 adjacent the nipple I5 is provided with a port 24 communicative with the chamber 1 and receives a valve 25 to which an air hose from an air pres- 10 sure system may be connected. The valve element 8 when in engagement with the stop 9 closes the port 24 and when in either of its positions uncovers the nipple l5. The valve element 8 when in either position uncovers the discharge l5 nipple I6 and when in one positionestablishes communication between the inlet nipple l8 and the nipple l8 and also connects the nipples l6 and I! and when in its other position establishes communication between the nipple l5 and the 20 nipple I! and also connects the nipple l6 and the nipple I 8. The valve element 8 permits the water pressure to be directed either into the top of the radiator or into the water jacket of theengine and when directing water into said water 25 jacket of the engine also air under pressure may be directed along with the water to dislodge foreign matter from the water jacket and the base of the radiator and discharge the same by way of the upper end of the radiator back into the 30 casing and from the latter by way of the discharge nipple l6. i

An extension 26 is formed on the casing 6 and is provided with a screw threaded socket to receive a stud bolt 21 for the purpose of securing 35 a suitable base 28 to the device.

Having described the invention, I claim:

A flusher comprising a casing, oppositely arranged inlet and outlet nipples in communication with the interior of the casing and said inlet ni p 40 ple adapted to be connected to a water pressure system, nipples in communication with said casing and arranged at opposite sides of the outlet nipple and adapted for connection to a device to be flushed, a valve operating in said casing and 45 movable to two positions for directing water alternatingly through the last-named nipples while permitting water from said device to discharge from the casing by way of said discharge nipple, stops in said-casing for limiting the movement of 50 the valve, said casing having a. port adjacent the inlet nipple closed by the valve when in one of its positions and open to the casing and one of said nipples at the side of the outlet nipple when the valve is in the other position,and a fitting 55 connected in said port to enable an air pressure system to be connected to the interior of the casing.
