This invention relates to lubricant and air dispensers especially adapted for servicing automobiles and has for the primary object, the provision of a device of the above stated character whereby the servicing of automobiles with air and lubricant may be greatly facilitated as to time labor and cost and permits the purchaser to view the lubricant as dispensed without leaving m the seat of the automobile anu obviates the employment of measuring containers of the conventional type.

Another object of this invention is the provision of means for dispensing the lubr cant directly to the engine of an automobile by air pressure and in predetermined amounts.

With these and other objects in view this invention consists in certain novel fea- 20 tures of construction, combination and arrangementof 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 drawings, in which Figure 1 is a vertical sectional view illustrating a lubricant and air dispenser constructed in accordance with my invention.

Serial No. 580,428.

Referring in detail to the drawings, the numeral 1 indicates a standard or support having the upper end thereof flared or of substantially cup-shape and on which is removably mounted a tank or reservoir 2 providing between itself and the standard a housing or chamber 3 in which are mounted hose reels 4 of the self-winding type. The hose from the reels are indicated at 5 and extend through apertures (3 and are provided with the usual fitting 7 for connecting the hose to inflating valves of tires. An air supply pipe 8 extends upwardly in the standard 1 from a suitable air supply and is connected to the hose 5 by pipes 9. The air supply pipe 8 is provided with the conventional type of moisture collecting trap 10. Pipes 11 and 12 are connected to the pipes 9 and extend outwardly of the chamher 3 and upwardly at opposite sides of the tank 2 and are provided with control valves 13.

The tank 2 is divided into chambers 14 for containing different grades of lubricant by partitions 15 and the chambers may be conveniently filled with the lubricant through openings 16 closed by removable caps 17 If desired the caps 17 may be pro vided with suitable looking or sealing means to prevent unauthorized tampering with the lubricant contained in said chambers 14.

Seats 18 are formed on the top wall of the tank 2 on which are mounted transparent containers 19 and the upper ends of said. containers are received by seats 20 formed on a cover 21. The containers 19 are in communication with the chambers 14 by pipes 22 that terminate adjacent the bottom wall of the tank and are provided at their upper ends with check valves 24.

The cover 21 is provided with a domeshaped upper wall 25 for the purpose of shedding rain and the like and supports an illuminating means 26.

The air pipe 11 is in communication with each of the chambers 14 whereby the lubricant therein may be placed under pressure for the purpose of forcing lubricant into the containers 19. The containers 19 are each provided with a suitable scale 27 whereby a person may easily determine the amount of lubricant within the container. A diskshaped float 28 is slidably mounted in each of the containers 19 and is preferably coated a suitable color to render the same easily noticeable. The float rides upon the lubricant within the container and by referring to the same and the scale, a person can easily determine the exact amount of lubricant within the container.

Conduits 29 are formed in the tank and their upper ends are in communication with the containers and their lower ends extend outwardly through the sides of the tank and are provided with fittings 30 for securing hose 31 thereto. The tank 2 is also provided with air conduits 32 in communication with the pipe 11 as shown at 33 and their lower ends extended through the side of the tank 1 and provided with fittings 34 to which air hose 35 are connected. The air hose 35 are joined with the lubricant dispensing hose 31 and the hose 31 and 35 are connected to nozzles 36 removably supported by brackets 37. The brackets 37 may be provided with a locking means 33 to prevent unauthorized removal of the nozzles. The brackets 37 are formed integral with attaching rods 39 employed for connecting the cover to the top wall of the tank 2.

The air pipe 12 is in communication with the upper ends of the containers above the floats and is provided with a two-way control valve 40 for the purpose of placing lubricant within the containers either unoer air pressure or under atmospheric pressure. In order to force the lubricant from the tank into the containers it is necessary that the latter be under atmospheric pressure and the valve 40 is positioned accordingly and to force the lubricant in the containers through the hose to the nozzles, air pressure is admitted to said containers by the proper positioning of the control valve 40.

Each of the nozzles includes a cylinder 41 closed at one end by a removable cap 42 and the opposite end formed integral with a discharge neck 43. A lubricant passage 44 is formed in the cylinder 41 and communicates with the interior thereof adjacent the neck 43 and is provided with a check valve 45 while the opposite end terminates in an extension 46 to which the lubricant hose 31 is connected whereby lubricant from one of the containers may pass into the cylinder. An air passage 47 is formed in the cylinder 41 and is of semi-circular shape as shown in Figure 10 with one end terminating into an extension 48 connected to the air hose 35 and the opposite end in communication with a chamber 49 in communication with the interior of the cylinder 41 and provider with a valve seat 50 controlled by a valve 51 normally urged into engagement with the seat by a spring 52. The valve 51 is provided with a stem 53, one end of which extends outwardly through a guide 54 in the cylinder and the opposite end extends through a stuffing gland 55 and pivoted to one end of a linger piece 56. The finger piece 56 extends parallel with the cylinder and a hand grip 57 formed on the cylinder and the other end 0 the finger piece is pivoted to a stem or rod 58 extending through a stuffing gland 59 into the neck 43 and has connected thereto a flexible element 60 which is connected to the stem 61 of an outlet valve 62 mounted in the discharge neck and normally held in a seated position by a spring 63, thus it will be seen that by moving the finger piece 56 toward the handle 57, the and 62 will be unseated and when fin er piece is released, the springs of 'd valves automatically move the latter into closed position.

A piston 64 is slidably mounted in the cylinder 41 and normally urged in one direction or toward the cap 42 by a coiled spring 65 dividing said cylinder into a lubricant chamber 66 and an air chamber 67. The air chamber 67 is provided with an atmospheric port 68 controlled by a valve 69 carried by the stem 53 and which also forms a support for the guide 54. When the valve 51 is in a seated position, the valve 69 is in an unseated position opening the air chamber 67 to the atmosphere and when said valve 51 is in an open position to admit air pressure to the chamber 67 the valve 69 moves into a seated position closing the atmospheric port 68.

The chamber 66 of the cylinder 41 is of a size to contain a predetermined amount of lubricant and when it is desired to dispense this amount of lubricant into the engine of an automobile, the neck 43 is disposed in the oil receiving conduit of the engine and the operator moves the finger piece 56 toward the hand grip 57 permitting air pressure to the chamber 67 which acts upon the piston forcing the lubricant within the chamber 66 into the engine and after the dispensing of the lubricant the finger piece 56 is released cutting oil the air pressure to the chamber 67 and the piston 64 'eturns to From the foregoing description taken in connect-ion with. the accompanying drawings it will be noted that a very simple and practical dispenser has been provided capable t supplying lubricant in desired amounts and also providing an efiicient supcent the handle for unseating port for air supplying means for inflating tires and the like and air pressure thereof is employed for dispensing the lubricant as desired, thus reserving space and also providing a device whereby an automobile may be easily and quickly serviced as to lubricant and air pressure. Further the device permits lubricant to be dispensed therefrom directly into the engine of an automobile without the employment of measuring containers consequently obviating waste or spilling of the lubricant and providing a much cleaner mode of supplying lubricant to automobiles.
