DISPENSING GUN FOR 'DECARBONIZING LQUIDSl Fild April so, 192'8 mark Las f' mi2.

This invention .relates tondispensing ap- A' paratus and more particularly to a device 4for injecting a charge of decarbonizing liquid into a cylinder of'an internal combustion 'engine.
-After a period of use the'walls of the combustionchambers of an explosive engine become coated with a carbon deposit'which quantity.
serves to lessenl engine efficiency. One method some times employed to remove they carbon deposit and restore engine eiliciency consists in pouring a liquid decarbonizing solution into the cylinders when the engine is hot. The engine is thenallowed to remain idle for a certain interval, in which the liquid acts upon and loosens the carbon coating. When the engine is again started the loosened carbon is blown or carried out the exhaust line. This deearbonizing liquid is usually sold in small cans or containers-and it is sometimes, difficult to pour the liquid from the can into the combustion chamberand in the proper It is an object of the present invention to provide a dispenser for the liquidwhich may be readilyattached toand used with a regular container in which the liquid'is purchased 'y on the market and which will allow a predetermined amount of liquid to be easily and conveniently injected into-the engine combust-ion chamber. l Another object of the invention is to provide a device with which is associated a pressure pump for forcing the liquid charge into the engine combustionl-chamberjand which -embodies a check-valve to prevent the liquid entering the pumpl cylinder.
A further object of the invention is to provide a device that will dispense only a pre- 'determined charge ,regardless of the number of pump strokes employed or the degree of pressure actin on the liquid.
A further o ject of the invention is to provide a device which will distribute'the liquidto every surface of the combustion chamber.
Other objects and advantages will be apparent from the following specification taken in connection with the accompanying drawing wherein: v
Figure 1 is a vertical sectional view of the 1928. Serial No. 273,946.
Referring to drawing the reference character. 1 indicates a hollow cylindrical body portion providing a measuring chamber 2, and from which projects a boss or reduced portion 3 fordetachable engagement with the screw-threaded neck or spout 4 of the can or container 5. An integral flange 6 in the opening through.the boss forms a seat for the plate or disk valve 7., controlling communication between the container 5 and measuring chamber 2, the tension of the coil sprinfr- 8 interposed between the valve 7 and a xed perforated plate 9 tending to urge the valve toward its seat. The cylindrical ,body portion is also provided with. a lateral projection or boss 10into which is threaded the end ofa pump cylinder 11, having therein a reciprocatory piston 12, preferably Aconsisting of'a leather cu mounted on one end of a stem 13 that extends through the cap or cover 11i-of the pump cylinder and has a handle 15 at its opposite end. The end of the pump cylinder 11 is closed by a plate 16 positioned between the end of the cylinder and a shoulder in the hollow boss 1 0, and having a skirt porvchamber 2.and forms an outlet 'passageway leading through the elbow fitting 21, a pipe or conduitl 22 to aglobular diffuser tip or spray nozzle 23, having a number of small perforations or holes therein.
In use the boss 3 is threaded on the spout PLUG COMPANY, or-
from the measuring chamber. l
4 of the liquid container in place of the customary closure cap. By turning the container upside down to the position shown in Figure 1 the liquid by its own weight opens the valve 7 and passes into and ills the chamber 2 and the outlet passageway leading to the nozzle 23. The smallness of the openings or perforations in the nozzle and the surface tension of the liquid 'prevents the liquid from passing through the-perforations without the .application of pump pressure. At this stage the parts are inverted or turned so that the container is top side up, when the valve 7 will return to its seat. TheA nozzle may then be inserted through the customary spark plug openings and into the combustion chamber of the engine whereupon operation of the pump will force the liquid in the measuring chamber through the nozzle. On the pressure'stroke of the pump the air that had passed the piston on the suction stroke is replaced by air entering theport 26 in the cap 14, 'and is forced past the checkv valve 17 to act on and cause the discharge of liquid through the `standpipe 20. The check valve 17 at all other times remains'c-losed, thereby preventing the entrance of liquid into the pump cylinder where it might tend to cause deterioration of the piston material and destroy its action. It will be apparent that when the level .of the liquidv falls below the open end of the standpipe the air under pressure will escape through the outlet and no longer cause liquid to be discharged. Thus the length of the standpipe determines the amount of thev liquid to be injected, and by substituting various len ths of volume determining tubes or conduits, dierent predeterminedl quantities of liquid may be dispensed according tothe size of .the engine as well as the extent `of the carbon deposit.
Figure 4 shows'a modied typejof check.
valve comprising a ball 30 that'may-be substituted forthesprin pressed plate valve heretofore described. nstead of employing a hand operated pressure pump for forcing out the liquidthe pump may be replaced by suitable nipple with which may be connected a compressed air line.
