June 2,.1931.. WEISSFLQCH I DEVICE FOR FILLING THE CRANK CASESOF IOTOR 'VEHICLES WITH LUBRICATING OIL Filed Dec. 15,1929

Patented June 2, 1931 UNITED STATES PATENT OFFICE KONRAD KARL WEISSFLOGH, F NUREMBERG, GERMANY DEVICE FOR FILLING THE CRANK CASES OF MOTOR VEHICLES WITH LU BRICATING OIL Application filed December 16, 1929, Serial No. 414,524, and in Germany December 7, 1928.

The invention relates to devices for filling the crank cases of motor vehicles with lubricating oil, similar to application Serial No. 257,903 filed by applicant on January 29,

1928. My present invention differs from the former device by the arrangement of a suction pipe, branching off from the filling hose in such a manner, that the lubricant is drawn by means of the pump from an oil tank through the suction pipe and delivered to a container, which is preferably of standardized capacity, and then is supplied by means of the same pump through the filling hose into the lubricant reservoir case of the motor vehicles.

In the accompanying drawings- Fig. 1 is a view in side elevation of the device, Fig. 2 is a section, taken on line A-A of Fig. 1 and Fig. 3 is a detail section of a modification of the branching part between the filling and the suction pipes.

The pump 1 is a rotary pump, the two rotors of which may be driven by a hand crank 2. The pump carries on the top a lubricating container 3 which may be suitably removed and at the bottom a T-shaped branching piece 4 provided with a cock 5. A flexible hose 6, serving as the filling means and a tube piece 7 are connected with the branching piece 4.. The filling hose 6, in front of which a strainer 8 (Fig. 3) is interposed, carries on its free end a mouth piece or nozzle 9, provided with a cook 10 and may be put in a spring clamp 11 of the container 3. The tube piece 7 is detachably connected with a tube 14 by .a screw coupling 13, a strainer 12 (Fig. 3)

being disposed between the

tubes

7 and 14.

A funnel 16 is slidably arranged on the tube 4 14 and may be fixed on the latter by means of a screw 15. The funnel 16 is connected with a sleeve 17, which may slide on the tube 14, the sleeve 17 having longitudinal projections 18, so that channels 18a; (Fig. 2')

4 are formed between the tube 14 and the sleeve.

The operation of the device is as follows:

The tube 14, on which the sliding funnel 16 is loosely arranged, will be introduced into a tank 19 or a storage barrel and then 'bile; The. desired quantity of l'ubricanthaving been discharged to the crank case, which quantity may be indicatedon a scale of the container 3, the cook .10, provided on the the funnel 16 is placed in the bunghole of the tank-or'storage barreland in this position fixed on the tube 14 by the clamp screw 15. Now the cock 5 is turned in such a position, that the pump 1 is connected with the tube 14, While the flexible hose 6 is cut off from the pump 1. On turning the crank 2 in the proper-direction, the pump 1 will charge the'lubricant from the tank 19 through the tube 14 into the container 3. In this way a) the air enters the tank 19 through the channels 18a existing between the sleeve 17 of the funnel 16 and the tube 14. A

When the desired quantity of lubricant is delivered into the container 3, the cock 5 i565 turned in' such a position, that the tube 14 is closed and the filling 'hose 6 is in communication with the pump 1; Now when the crank 2 is turned in the opposite direction, the pump lpresses the lubricant from the container into the filling hose, from which the lubricant will be charged to the reservoir case of an engine, as for instance to the crank case of the motor of an automomouth piece 9 of the filling hose 6 will be closed and thus will prevent the lubricant 8 still contained in the hose from escaping. The lubricant, which may overflow the container 3 or run down on the outside of the device because of leakage of some part, will be received nnel 16 and redel'ivered 8;

to the tank 19.

Instead. ofthe manifold cock 5 (Fig. 1) a non-returnvalve may be disposedtogether wlth an ordinary cock in the branching piece 4.. The branching piece 4 according to Fig. 3 has the same construction as that in 1, only with the difference, that in the T- shaped piece 4 a ball valve 20 isarranged, serv ng as a non-return valve, while the connectlon portion with the filling hose contains an ordinary cook 21. A

The discharge of the lubricant from the tank 19 is effected by the operation of the. pump 1 when the cock 21 is closed. When the container 3 is filled, the cock 21 will be opened and the pump 1 driven by hand but now in the opposite direction. 'After this the lubricant will be delivered into the filling hose 6 from the container 3, the non-return valve 20 being closed during this process.

In both constructions the device may be removed from the tube 1 1 by the screv; nut 13 being removed. It canthenbe carried by hand to the place Where the oil is to be filled into a crankcase.

WVith the invention the usual strainer in the crankcase of a. motor vehickmay be.

omitted, because the lubricant itself Will be strained twice, namely, once by the strainer 12 in the tube 14 and the second time by the strainer 8 in thefilling hose 6;

If it is. nevertheless. desired to, maintain the strainelf at the inlet opening of the crank case, it: is. necessary thatthe. mouth piece of the filling conduction 6 should be brought, into a secure and firm connec iQll Withthe inlet, pipe ot the crank case during the filling of the lubricant, in order-that; the lubricant can. be. pressed; through this. strain er by means of thepump 1-. In this case both strainers themselves. may be. omitted; in the device. Instead; of the container 3 a pipe connection mayalso be connected; With the. pump 1 it for instance the. device should beemployed for filling lubricant'out of 011. tank, barrel or reservoin into. another. The rotary pump can. alsobe replaced by; a. pump of'another. type.

What I claim, is: I

1; A portable liquid; Withdrawing and dispensing device including a liquid; C 11.- tainer, a reversible liquid-pump havringports therein, one of the ports. communicating with the. bottom. of the container, branched conduits connected with the. other portpf thepump, oneof said bnanchesbeing: adaptedfor immersion in. a. body ofliquid. during the filling of the container during. rotation of the pump in. one-direction and 'the other branch being adapted to conduct liquidto a desired point ofadeliveryi during, operation ofthe. pump; in theiopposite direction, and means for connecting the second. mentioned port. of the pump alternately with. the. first and second mentioned. branches 2. A device as claimed in claim 1, characterized in that the. second. mentioned; branch is; provided with avalve adjacent its terminal;

In testimony whereof I have. signed my nameto this specification.
