110laims. (01. 226-96) This invention relates to improvements in apparatus for filling receptacles with fluid. More particularly it relates to an improved apparatus for filling cans with grease.

It is an object of this invention to provide a rotary apparatus for successively measuring predetermined quantities of grease and for successively ejecting the measured grease into suitable rceptacles.

It is a further object to provide a construction whereby the measuring cylinders are filled at one location and are discharged at a separaterlocation." Still another object is to control the operation 0! filling the measuring cylinders with grease and the ejection of the grease from the cylinders while the cylinders are in motion.

Referring. particularly to the drawings, referdevice. A tubular supporting column 2 extends upwardly from the bed plate I." The supporting column is'divided by a bottom plate .3 and a top plate A to term a reservoir '5 for the fluid-such as grease. The grease is supplied to the reservoir 5 through a conduit i bymeans of a suitable pump 1, under a suitable pressure such-as approximately 4 pounds per square inch. A; cylinder 8 commuq nicates with the pp oi the reservoir porting truck of the side view of valve head .21 is provided at ence numeral l designates the bed plate or suppiston rod which is fixed in position provided with a laterally elongated exhaust port ii for delivery of grease from the reservoir. The piston I0 is weighted sufiiciently to maintain a uniform flow of grease through the exhaust port 15 even though there should be a variation in the pump pressure upon the grease 10 entering the reservoir 5 which might cause uneven flow or grease into the reservoir.

The lubricant is delivered from the reservoir 5 to a measuring and distributing apparatus which is rotatably mounted with respect tothelB tubular support column 2. The measuring apparatus comprises a tubular bracket 20' which is rotatably supported upon anannular flange H which projects outwardly from the supporting column 2. The tubular bracket 20 is pro- 20 vided at its opposite ends with gland nuts 22, the lower one of which revolves upon a thrust roller bearing 23. A stufiing box 24 is provided 1 at top and bottom of the bracket 20. The bracket 20 is driven in rotation in a clockwise 2 direction as viewed in Fig. 3 in a manner to be later described. A plurality of measuring cylinders a to p inclusive are supported radially exteriorly oi the bracket 20. Empty cans X which are to be filled with grease are fed from a table 25 manually or otherwise to a revolving table 26 between spacing fingers 25a.

The measuring cylinders are tioned in a circle just above the pockets ormed by the spacing pins 260.. The measuring cylinders each include a cylindrical body 21 which is connected adjacent its base to the bracket 2!. by means or a tubular'arm 28. Theinterior of each tubular arm 28 communicatcswith one 0! a plurality of openings 28 on the-bracket 20. The cylinder 40 itsbpttom with a hopper 3| having a discharge opening 32. A valve a extends across the cylinder above the hopp r. The valve seat}? is provided with a plurality; such as seven, oi. spaced orifices 34. A valve disposed 3 within the cylinder has a valve head 38 extending across the cylinder, and a valve stem 31 projecting upwardly from the valve head. The valve head is provided with a plurality such as seven openings 38. The valve is adapted to be rotated so as'to successively align and disalign theopenings 38 with'the orifices 34, see Figs. 8, 9, 10 and 11. The capacity of the cylinder is varied by means of an adjustable cover 45.

The grease is ejected from the measuring cylinder by means of a piston 46 having a tubularl'l. The piston 46 is reciprocable I the cylinder as far asring 48 within the cylinder at downwardly in theopening of the passageway 28 with the interior of the cylinder. The ring 48 is perforated to permit passage of grease into the cylinder. The ring 48 prevents the valve 36 from rising in the cylinder and prevents the piston 46 from dropping below the port opening. The valve stem 31 extends non-rotatably through the piston head 46 into the tubular piston rod 41 whereby the piston can be reciprocated longitudinally of the .valve stem and rotation of the,

piston causes rotation of the valve stem. The piston rod carries at its upper end a. vertically facing roll 49 which is adapted to engage a cam 58 for forcing the piston downwardly in the cylinder to eject grease from the cylinder into -a receptacle. The cam ,56 is positioned to be eneject the grease from the cylinders into the cans The valve 36 for opening and closing the bottom of the measuring cylinder is actuated by the following arrangement of parts: The piston rod is provided with laterally extending brackets 51 and 68, see Figs. 12 and '13, which carry laterally facing cam rolls 58 and 66 respectively. The mils 68 and 66 follow the side walls 6| and 62 respectively of an annular camway 63 formed in the cover plate 4. The walls 6| and 62 of the camway are inclined radially inwardly at 64 and 66 respectively and are inclined radially outwardly at 66 and 61 respectively, as clearly shown in Figs. 3 and 6. As the assembly of measuring cylinders rotates in a clockwise direction, as viewed in Fig. 3, the roll 69 in passing from the position of measuring cylinder a to that of measuring cylinder b engages the inclined surface 64 oi the camway' retarding the movement of the roll 68 sufliciently to cause the piston rod 41 to be rotated about its longitudinal axis thereby turning the valve 86 to bring the ports 88 and 84 into alignment to permit discharge of grease from the measuring cylinder. The discharge openings are maintained in alignment from the position of the measuring cylinder b to the position of the measuring cylinder i. during which period the grease ejecting piston 46 is descending within the cylinder.

Upon leaving the position of the measuring cylinder i the roll 66 is caused to ride up the radially outwardly inclined wall 61 of the camway thereby retarding the peripheral movement of the cam roll 66 and causing the piston rod 41 to be rotated about its longitudinal axis, thereby turning the valve 36 sufiiciently to bring theports 88 and 34 at the bottom of the measuring cylinder out of alignment.' The valve 86 is closed in the bottom of the measuring cylinder .and the cylinder is ready to receive a new charge of grease. The cans X are thus filled with greasein predetermined amounts such as one pound. Upon continued rotation of the table 28, the filled cans are engaged by a tapered arm 16 which diverts the cans away from the revolving table 28.

Upon continued rotation of the measuring cylinder assembly the inlet port 26 to each measuring cylinder is brought into alignment with the oblong port I! in the walloi reservoir 5. Pressure is maintained in the reservoir 6 by a grease pump and the weighted piston. The valve 36 being in closed position, the grease is injected into the measuring cylinder under suificient pressure to elevate the piston 46 to its uppermost position thus filling the measuring cylinder with a predetermined amount of grease. Further rotation of the assembly in' a clockwise direction, as viewed in Fig. 3, brings the refilled measuring cylinder to the position indicated at a where a fresh can is positioned beneath the measuring cylinder. 4

The assembly is driven in rotation by means of a motor 86 which actuates a worm shaft gear 8|; see Figs. 1 and 2. A worm, not shown, driven by the worm gear 8| drives a worm gear 82. The worm gear 82 drives a shaft 83 and an operating pinion 84 which meshes with a gear 85 aifixed'to the rotatable table 26.

By the construction described, the measuring cylinders 21 are filled at one place and are discharged at another. A plurality such as seven measuring cylinders are permitted to discharge grease at the same time, and the grease in the cans is allowed to level and not pile up. The valve 36 is .opened and closed and the piston 46 is pressed down while the cylinders 21 are in piston 46 is in either its upperor .lower position, since the valve stem 31 reciprocates in the hollow piston rod 41.

Various changes may be made within the scope of theappended claims in which it is desired to claim all novelty inherent in the invention as broadly as the prior art permits.
