Tb all whom it may concernf Be it known that I, AVERIL P. Armniisolgi,

- a citizensof the United States, residing at Bellevue, in the county' of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Lubricatin Systems, of-which the following. is a 1 sp'eci cation. l

This invention relates to lubricating systems and more especially to centrallyoper- .ated grease lubricating automobiles.

systems for use on One of the principal objects of this inveri tion is to provide a lubricatingsystem which enables all parts of ,an automobile vto be lubricated by the automobile driver directly from his seat. Another object is to provide means for using fluid pressure to efi'ectthe lubrication of the various parts of the auto-' A further object .is; to provide means for regulating the amount of lubrication in relation to the requirements oithe various parts. to be lubricated. Still a further object is to provide a lubricating v system which can be replenished with rapidity and without waste and. which is of simple construction and operationj Further objects and advantages of my, lubricating system will appear fromfthe specification and drawings which form a part of this application.

In the drawings:

Figure l is a general view, partly in seetion, showing one application of my luhri" eating system.

Figure 2 is a top plan view of the greasecontainer used in'Fi'gure 1.

Referring to Figures 1 and'2, my lubricating system consistsof a grease container 1.

Application for i in the piston. Cent-rally of the screwed-on,

cover-6 is secured a guide-rod'7 which acts as 'a guide for the movements of the piston.

-A hiib 8 is cast on the upper part of the piston to give a greater contact between the \60 a piston and the guide-rod. .The latter-has at its lower end a button 9 which may engage a depression 10 provided in the underside of the piston to permit thecomplete extru-' sion of the. lubricant within the container. The purpose of this button is to prevent the piston from leaving the guide-rod and to en'- able the removal of said-piston by means of the cover 6. This cover is applied to the grease container by; means of the hexagonal head 11 cast integrally thereon; a 'sultable gasket 12 is also provided to insure 21. hermetic engagement betweenthe cover and the container. The latter is provided with feet i -or lugsl3, by which it may be securely mounted at any suitable place on the automobile. Y

The lubricant may beintroduced into the container either from the top by removing the cover 6 and the depending piston 2 or gun to the pipe c0nnection 14 which is norao else from the bottom by connecting. a greasemally sealed by the cap 15 and the gasket 16. The lubricating grease is fed to the va- A riious parts of the automobile which are to be lubricated by meansof the numerous outlets 17 provided at 'the bottom of the, grease container. As shown in'Figure 1, the con -nection between said outlets and the parts to be lubricated is efi'ected by means of the unions' 1 8, the feed tubes 19, the pipe fit tings 20, the branch tubes 21 which are connectedto'the parts to be lubricated in any suitable manner, such as by the unions 22. The feed and branch tubes 'are preferably 'made of small and flexible copper tubing,

but if desired, any other suitable material. Y

may be used.

As the lubrication requirements vary for the different parts of an. automobile, I'pro vide, near or at the parts to 'be lubricated to suit the local conditions.

The lubricant is forced {to the various parts by means of air pressure which is ob tained from a high pressure air tank 24 connected to the (grease container by means of the pipe 25 an' is screwed into the boss 27, providedoutw r ly he n a n r, As

thepipe nipple 26 which 'llustreted in.

. the cooks 23 which are opened more or less Figure 1, the air is introduced above the piston through the obliquely drilled hole 28 which reaches near' the top edge, of the grease container. By using the -construc-' tion-just described, it will be seen" that the cover 6 -may be removed without affecting the air pipe connection tothe container.

.Theair sup ly to the latter is established and regulated y means of a. three-way cock grammatically illustrated in Figures 7 to 9 inclusive. In these figures, is the pipe connection to the grease container, 31 is the connection to, the air tank" and '32 is an air vent. The position indicated in igure 7 shows that the air tank and the grease container are directly connected, Figure 8 shows the air sup container vented? tion with theatmosphere. Figure 9 indicates that both the air tank and the grease container are shut ofi'.

The air tank is usually provided with a pressure gauge 33' "and an inlet connection 34 through which air at high pressure is introduced into the tank. The air tank may be located at any suitable 1pl tomobile, but itfis preferab y positioned un-' der the hood. of the automobile and the air pipe 25 is so directed'as to bring the threeway cock 290m to the dash-board of the authe driver. I p v Figure 3, I have shown a modification of my lubricating system in which the piston mechanism has been eliminated and the gen' eral construction greatly simplified. .Instead of filling the grease into the container, theformei is supplied in a collapsible tube 35 which is inserted into an air-chamber 36 and screwed tightly into the cap-member 37 which 'connects by means of the threaded shank-38 to a manifold pipe 39 closed at both ends and provided with the desired number of grease-outlets 40,"identical to those disclosed in Figure 1. The air pressure from the air tank is introduced into the air-chamber. by the pipe 25 and nipple 26 screwed on to the boss 41 rovided on the air chamber. As will 'be rea y understood, I when compressed air is introduced .in the air-chamber, it will compress the collapsible tube and force the lubricant into the manifold until he collapsible tube is emptied. By flattening both ends of the ures 3 and 4, the tube willbe collapsed" su stan'tially flat'in the same plane as the ends and practically all the grease will be forced out. 1 i

The construction shown in Figure 4 differs from that of Figure 3 only 1n that the airchamber has been provided'with two oppositely disposed collapsible grease tubes hich pp y in i idu men f ldp p 39 29 which allows the various connections die-- 1y shut-ofl' and the greasethat is, in communicaace on the automobile so as to be within easy reach of collapsibletube as shown by shading in Fi charge opening of the lubricant The compressed air is introduced in the air chamber through a sin le pipe connection represented by the pipe 25 and the nipple 26. .This arrangement is especially valuable when'it is necessary to lubricate various parts with. different kinds of lubricants, as

often the case in automobile practice.

" Having described the mostessential parts of my lubricating system, the operation thereof will be easily understood andis as follows: To lubricate the various parts of J an automobile, the driver thereof turns the three-way cock in the position shown"in' Figure 7, thus introducing compressed'air in the grease container 1, or the air-chamber 36, and, forcing out the lubricant to the various parts of the machine. After. a short time, judged sufliciently to supply the re quired lubrication, the three-way cock is turned in the position indicated by Figure 8, thus shut-ting ofi the supply of compressed air and-relieving, or venting, the greasecoir tainer. This venting is done for the purpose of preventing any waste of lubricant which would occur were the grease in the container left subject to the expansive force of the compressed air left therein, if the cock were turned directly in the fullshut-ofi position illustrated in Figure9.

In. the above description, mention has been made of the use of my lubricating system tion with automobiles. It is evident that the system can be used as ,well with lubricating oils and in connection with any desired kind of machinery.

As will be understood, as suggested herein, there may be slight changes made, in the construction and arrangement of the details of my invention without departing from the field and scope thereof, and I intend to ina scope of the appended claims.
