To all whom it may concern.

Be it known that I, JAMES E. FERGUSON, a citizen of the United States, residing at Dwight, in the county of Livingston and State of Illinois, have invented a new and useful Lubricant-Dispenser, of which the following is a specification.

he present invention relates to improvements in a lubricant dispenser, one object of the invention being the provision of a novel and improved dispensing machine adapted to be used in garages. or elsewhere for use in dispensing heavy oils, such as grease, and other liquid or semi-liquid substances.

Another object of the invention being the provision of a novel mechanism, wherein a main supply has means simultaneously operated to deliver into a dispensing chamber, a predetermined quantity of lubricant, said dispensing chamber being with means for projecting the lubr cant thereupon as dispensed and for simultaneously cutting off communication between the chamber and the main supply tank.

A further object of the present invention, is the provision of a device of this character which may be easily operated without soiling the clothes and hands of the operator and which by the simple manipulation of a crank connected to a single shaft will operate mechanisms for removing a predetermined amount of lubricant from the main supply tank to a dispensing chamber and for removing the same lubricant from such chamber as desired.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the detzfils of construction hereinafter describedand claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

ln the drawings, Figure 1 is a view partly in elevation and partly in section ofthe complete mechanism, the respective pistons of the main tank and the dispensmgchamber being in intermediate position. Fig. 2 1s a top plan view of the complete mechanism.

*ig. 3 the lower ing the dispensing chamber. plan view of the dispensing is an enlarged detail sectional view of portion of the supply tank show- Fig. 4 is a top chamber showfurther provided ing a portion of the tank in section and the feed screw for the plunger of the dispensing chamber in section. Fig. 5 is a section taken on line 5'5 of Fig. 3. Fig. 6 is a section taken on line 66 of Fig. 3.

Referring to the drawings, the numeral 1 designates the cylindrical walls of a main dispensing or supplying chamber or tank, which is provided with the removable disk bottom 2, with the center bearing opening 3 for the feed screw 4, said feed screw 4 is of substantially the same length as the cylindrical portion of the tank and is provided at its upper end with the squared portion 7, while mounted intermediate upon the screw for movement up and down as the screw is rotated, is the disk plunger 5, which is proarms 6, which constitute a: means for engaging the lubricant within the tank to hold the disk against rotating during the longitudinal movement thereof upon the screw. It is also apparent that the disk 5 may be held against rotation by other means as for instance as a spline connected to the periphery thereof in the interior of the tank '1. but it has been found in practice that the radial arms 6 are all that is necessary inasmuch as the lubricant is usually a stiff grease and therefore offers sufiicient resistance to maintain the disk 5 against rotation.

The upper end 7 of the feed screw 4 is adapted to fit Within the squared socket 8 of the short or stub shaft 9,which is rotatably mounted in the removable cover or disk 10 of the tank'l. This cover 10 is adapted to be held in place by means of the arm 11 which is connected to the upper surface of the cover and the hook 12. This renders it necessary to slightly oscillate the cover 10 so as to disengage the arm 11 from the hook 12 when it is desired to remove the cover 10 and fill the tankas will later ap pear. A large bevel gear 13 is carried by the shaft 9 and consequently by the cover 10, while also carried by the cover 10 to one side thereof is the bracket 14, which is provided with the pivoted member 15 which is normally held in encircling relation by means of the thumb screw 16, so that the short section 17 of the shaft may be properly journaled therein with the parts in the position as shown in Figs. 1 and 2, or whereby the member 15 may be thrown backwardly to permit the shaft'17 to be elevated upon its hinge joint 19 so as to place the gear 18 out of mesh with the gear 13 and such position. At this time, the port 30 thus perm't the removal of the cover 10 to has been moved from registration with the have access to the tank 1. port 28 to registration with the ports 27 The other section 20 of the drive shaft is and 26 and the plunger 36 is in its lowerjournaled upon the bracket 14 so that the most position, having expelled the lubricant 0 brackets 14 and 14' constitute a support within the shell 30 through the ports 30', for'the shaft consisting of the sections 17 28 and through the dispensing pipe 29 to and 20. Clutch members 21 and 22 are carany desired place. ried by the shaft sections and the spring There is connected to the upper end of the .23 normally holds the clutch members tofeed screw 34, a sleeve 43, which Is further 75 gether, so: that when the crank 24 is rotated provided with the rectangular bore 44 for counter clockwise, the ear 18 is rotated and the sliding reception of the rectangular stem consequently the fee screw 4, the same 45 of the shaft 46, said shaft 46 being ourbeing movedto the left so that the plunger naled in the support 14' and carrying the 5 6 is moved downwardly and the plunger 36, gear 47 which is in mesh at all times with 80 as will presently appear is moved upwardly. the gear 48 fixed upon the shaft 20. Thus When thecrank 24 is moved in the opposite 1t Wlll be seen that when the crank 24 1s direction, the clutch members 21 and 22 do moved 1n either direction, the gear 48 will not engageand ther f r th screw 4 r transmit motion to the ear 47 and conse- 'i t ti ary wh'l th rew 34 a d its quently rotate the sha t 46, the tubular 85 piston 36 as'will later appear is rotated to m m er 43 and the feed screw 34. move downwardly. 1 \Vhen it is desired to fill the tank 1 with Connected to one side ofthe tank 1 near the lubricant, the thumb screw 16 is operth b tt m th fi th yli dri al mated to release the hihging member 15 so 25 h 25, hi h e titutes the dispensing hat the shaft section 17 carrying the gear 90 member of the present apparatus. There 18 may be swung upwardly and away from is provided in one wall thereof, an inlet the upper end of the tank 1 and out of ent, 26, which i l d i r gistr ti n with gagement with the gear 13. The cover 10 IS the. outlet port 27 of the tank 1 so that then rotated to release the arm 11 from the 30 lubricant within the tank 1 may be fed hook 12, at which time, the cover maybe re- 95 within the dispensing member through the moved. The feed screw 4 is now removed ports 27- and 26, there being disposed to carryingwith it the plunger 6. The plunger aline the member 25, an oscillatory shell 30, 6 18 then removed from the feed screw and which is rovided with the port 30 disposed the feed screw replaced with its lower end to be placed into and out of registration within the socket 3, at which time the lubriog with the

respective ports

After The upper end of the shell 30 is connected the tank has been filled with the lubricant, by means of the screw 31 to the disk 32. the plunger 6 1S placed upon the feed screw This disk 32 is provided with the threaded 4 and the cover 10 is placed in position in 0 opening for the reception of the feed screw the upper end, the arm 11 being rotated to 105 34, whose lower, end is connected by means engage the hook 12. The shaft section 17 is of the yoke 35 to the piston 36. Thus the now lowered so that the gear 18 is placed in disk 32 andthe shell 30. are connected for mesh with the gear 13 and the hinge mem-' movement together and in order to impart ber 15 is locked downwardly by means of 5 movement to the piston 36 as the feed screw the thumb screw 16. Thus the parts are 11 34 is rotated, such disk 32 must be 'mainnow in position for operation. tained in a stationary position. This 'is ac- Assuming that the plunger 6 is at the top complished by means of the spring actuated and therefore the plunger 36 is at the botpawl 38 adapted to seat Within the recess 37 tom of the shell 30, the

ports

Thus bottom through the

The threads upon the feed 1 the shell 30 will be rotated with the feed screws 4 and 34 are so regulated that the screw 34 so as to cause the pin 42 to ride disk 6 moves longitudinally within the tank in the arcuate slot 41 formed in the cover 1 a sufficient distance only to cause a sufii- 36' and finally to engage the spring clip cient quantity of lubricant to be ejected into 43 which holds and receives the pin 42 in the shell 30 to fill the same, while the plun 1 ger 36 is moved from the extreme lower end of the shell to the upper end thereof. As the plunger 36 approaches the disk 32, the pin 42 having been seated within the spring clip 43, and therefore held against rotation, the frictional rotation of the plunger 36 at the under side of the disk 32 and the continued rotation of the screw 34 will cause the disk to be rotated in the opposite direction or until the pin 42 assumes the position as shown in Fig. 4, at which time the spring actuated lock 38 will snap in the recess 37 and thus lock the disk 32 and the shell 30 in such position. The shell during this rotation is moved to cause the port 30 to be placed from registration with the

ports

27 and 26 into registration with the port 28 so that communication is shut off from the tank 1.

When it desired to dispense the lubricant from the member 25 through the pipe 29, the crank 24 is operated clockwise at which time, the clutch members '21 and 22 remain inoperative and therefore the screw 4 is not operated. The shaft 46 then operates the screw 34 to cause the plunger 36 to be moved downwardly. Thus as the plunger 36 is moved downwardly, the lubricant is ejected through the

ports

30 and 28 into the pipe 29. As the plunger 36 approaches the lower end of the member 25, the disk 40 is brought within the recess 39 of the cover 36 and engages the spring actuated lock 38 to release tliesame from its recess 37 so that the continued rotation of the screw 34 will produce sufficient friction upon the threaded portion 33 of the disk 32 to rotate such disk so that the pin 42 is moved from the position as shown in Fig. 4 to engage the spring clip 43, or at the extreme end of the arcuate slot 44. At that time, the shell 30 is rotated so as to place-the port 30' out of registration with the port 28 and into registration with the ports 2'1 and 26.
