GREASE nIsPiszNslm Application llled Hay 15, 1922, Serial No. 561,080. ilenewed December 3, 1930.

Our' invention relates to dispensing apparatus for plastic and semi-fluid materials, more particularly to an apparatus fordischarging greases, oils, aste or heavy or Nviscous Huid in measured) quantity.

The present application is a continuation in part our pending applications for Letters Patent Serial No. 453,97 8 filed March 21,

the commodity during such period of operation, by eliminating air pockets in the body of the discharged'commodity, and preventing back leakage'in the feeding mechanism.

The object of the invention 1s to simplify the structure as well as thel means and mode of operation of such apparatus, whereby it will notr only be cheapened in-construetion, but' will be ffno're efficient in use, positive in operation, uniform in action, accurate andv unlikely to get out of repair.' f. l

A further object of the invention is to provide a one man apparatus, wherebya single operator in charge of the discharge nozzle, ata remote point from-the supply reservoir and feeding apparatus, may control such` apparatus, wlthout necessitating a second operator for manipulating the dispensing mechanism. The structure is 'particularly-applicable for feeding lubricant or grease 1n a garage for filling transmission and diferential casings of motor'l vehicles. With the type of apparatus now in common use, one operator is requiredjto 'operate the pump or dispensing means', while a second operator holds the nozzleof the discharge hose or conduit in the supply orilice of the transmission or differential casing, and signals the pump' operator when grease is to besupplied or its supply arrested. The present invention is designed to place the entire operation under control of a single operator who is charge modity. This timer, involves an automativcally driven circuit breaker which will' interrupt the motor circuit with minimum arcing, with means for again setting it in operation from a distant polnt.

' A further object of the invention is to provide adjustable means by which the extent of the periodic operation may be varied to accommodate thel apparatus to feeding commodities lof different consistencies or different character.

A further object of the invention is tp proj vide an improved form of auxiliary pump or booster with means forpreventin any yieldy ing or leakage under influence o back pressure, thereby insuring the delivery of a full measured quantity at each operative period.

A further object of the invention is to provide improved screw feed dispensing means of such character anfd capacity in relation with the discharge capacity of the apparatus, as to effectively prevent the forming of airv pockets and the assurance of the delivery of a continuous and solid stream of dispensed commodity.

With the above primary and other incidental objects in view as Will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents asA hereinafter describedland set forth in the claims.

Like parts are indicated by similar characters of reference throughout the several views.

Referring to the drawings of the preferred embodiment ofthe invention, 1 is the container or reservoir for the material to be dispensed in measured quantity. This reservoir or container rests upon a base 2, within which is contained the ejecting apparatus.

The base or housing; `2.is provided with an ocket or chamber 4,.with which the open ottom of the reservoir or container 1 open registers.' Within the bottom of the chamber or pocket 4 of the base 2, there are formed a plurality of parallel semi-circular grooves or recesses 5, terminating at one side of the chamber 4 in concentric bores or circular passages 6, which form continuations of the grooves 5, in the base or housing 2, and which extend beyond the chamber or receiving pocket 4. Located in each of the semi-circular grooves 5 and extending thenceinto the corresponding bore or passage 6, is a revoluble spiral conveyor 7. There may be any number of these spiral conveyors in the series.

In the drawings, but four have been shown. It is obvious that more or less number of such conveyors ma' be employed. The conveyors 7 extend a su cient distance through the passages or bore 6 to afford ample bearing therein, for one end of the conveyor screw,`while at their o posite ends, they are provided with suitale bearings in the wall of the chamber 4 .and are furthermore linterconnected one with the other, for rotation in unison by intermeshing gear pinions 10.

Asv shown in the drawings, the pitch of the succeeding conveyor screws is reversed, and

y these conveyors are rotated in reverse direcmeter casing being I i -conveyor facilitates the gathering o tion by the intermeshing gear pinions `10, whereb the conveyors simultaneously advance t e plastic or semi-fluid materials uniformly in the same direction, that is to say, toward the bores 6, through which the commodity is discharged from the chamber 4. Inpractice, the rotation of these screws, one toward the other, forms intermediate the conveyors of each pair, a ridge of material, which is uniformly advanced toward the discharge ends ofthe conveyors within the bores 6, as the conveyors are4 rotated. It will be noted in Fig. 4, that the pitch of the conveyor screws is not uniform,. but gradually decreases as it approaches the discharge end of the conveyor screw. This variable itzlh t e commodity'from the distant side of the container or reservoir, advancing it toward the discharge outlet, where it is subject to gradually increasing pressure, as the rate of speed across the chamber 4 decreases.

The trunnion shaft of one of the conveyor screws extends beyond the chamber 4, as indicated at 11, to afford a driving connection for the series of conveyor screws, 7. VThese consion 11, of the initial screw conveyor of the series is provided with a bevel gear pinion 12, meshingwith a like pinion 13 upon a vertically disposed power shaft 14. The -drive shaft or power shaft 14, carries a worm wheel 15, withv which meshes a driving worm upon the armature shaft vof an electric motor 17. Upon the operation of the driving motor 17,

'the spiral conveyors 7 are simultaneously actuated through the iniiuence of the worm 16, meshin `with the Iworm wheel 15 upon the power sha t 14, and interconnectin pinions 12 and 13 to discharge the commo ity from the container or reservoir 1, through the lateral bores 6 of the Ybase 2, into la pressure communicate with this pressure chamber, and

simultaneously discharge thereinto.

To provide for hand manipulationpin the event of an emergency, or for use under abnormal conditions, the upper endlof the power shaft 14 is provided with a bevel pinion 19, meshing with a similar gear upon a transverse. shaft 20, to which maybe connected a detachable hand crank 21, for hand actuation of the apparatus. To permit such operation independent of the motor` 17, the

worm wheel 15 is preferably though notv necessarilyy connected to the=power shaft/14;

by means of a pawl and ratchet connection,"..

shown at 22, whereby the power sha-ft 14 may' be rotated in an advance `or forward dile'ction by means of the hand crank, -independent of the worm wheel 15, during which advance movement, the pawl will ride idly, over the teeth of the ratchet wheel. However, upon operation of the motor and consequent rotation of the `worm wheel 15, the pawl carried by such worm wheel will operatively engage the ratchet wheel which is fixedly secured upon the power shaft to drive the power shaft in unison. Such pawl and ratchet c onnection is shown for illustrative purposes only. it being obviousthat any suitable form of engaging clutch mechanism may be substituted therefor.

Leading from the pressure chamber 18 of the base or housing 2, is a discharge. conduit `comprising preferably a flexible hose 23 of such character as to withstand the high pressure under which the commodity is delivered. There are upon the market at the present time, various forms of metallic flexible hose and metal bound or armored hose, which are suitable for this purpose. Located at the outlet of the pressure chamber 18 to the hose connection 23 is a rotary power driven meter 24, comprising a cylindrical housing 25, having inlet and outlet passages 26 and 27. Mounted eccentrically within the circular housing 25, is a rotor 28, having therein two oppositely disposed overlapping slidlng blades or vanes 29. These vanes are slotted or formed with registering recesses in their inner or overlapping portions to receive springs 30 by which the blades or vanes are forced apart, and against the wall of the housing 25 as the rotor 28 revolves. During the rotation of the rotor, the blades or vanes reciprocate to and fro therethrough, due to the eccentricity of the wall of the housin 25, and the axis of rotation of the rotor. he blades or vanes maintain, lat all times, their bearing contact upon the interior Walls of the cylinder under the influence of the springs 30.'

The rotor 28 is positively driven by means of a bevel gear 31, upon the rotor shaft, which intermeshes with a similar gear 32, upon an extended stem or shaft of one of the spiral conveyors 7, which projects through the pressure chamber 18, and through a suitable stuffing box, 33A, to support on its outer end, the said gear pinion, 32. The rotary meter is thus positively driven in unison with the actuation of the spiral conveyors 7.A The capacity of the spiral conveyors 7 1s very muchl greater than the capacity of the meter, through which the discharged commodity must pass. The result of this preponderance of feeding capacity of the conveyor 1s to maintain a supply of commodit under pressure within the chamber 18. he conveyors feed the commodity to the chamber 1.8 very much faster than the meter, will permlt it to discharge therefrom. The result is that the surplus material is squeezed back, along the spirals of the conveyors 7. but the chamber 18 is always maintained lled to its en" tire capacity. vOneiof the purposes of this oversupply of commodity to the chamber 18,

in quantitles greater than is permitted to escape lthrough the meter, is to insure the avoidance of air pockets and to assure a continuous dischar e of uniform density. Any en# trappe air is permitted to escape rearwardly through the bore 6 with the surplus material, which is squeezed backwardly or overflows the spiral flute of the conveyor. Without some such provision, the feeding of the commodity would be spasmodic and the discharged material would be inclined to splutter due to the expansion of small pockets of vcompressed air as the material leaves the clischarge nozzle. Moreover, there would be no assurance of full measured quantity. The quantity discharged would vary as part of the bulk would be compensated forby such pockets of air.' Moreover, in such case the entrapped or entrained pockets of air would conduce varying density of the material at different points in the discharge.

By providing the vfeeding apparatus and the meter in tandemrelation, but with different capacities whereby the meter is supplied with a quantity of commodity greater than its capacity to measure, a full charge to the meter is insured at each rotation, and the density of the successive charges will be uniform.

In order to prevent back leakage, through the meter, or any slight variation of the blades or vanes of the meter rotor, due to back pressure within the discharge conduit 23, means is provided for advancing theblades or vanes into close operative contact with the .walls of the4 meter casing' 25, during the operative stroke of such blades or vanes. 'l This positive actuating means for the meter'blade operates entirely independent of the spring 30. It consists of notches or grooves 33 formed in the ends of the vanes or blades 29, which engage over-cam beads or flanges 33',

projecting inwardly from the heads of the.

meter casing 25. The construction is such that as the blade 29 approaches its operative position or point of greatest stress, that is to say, as it passes the inlet orifice 2'6-,fthe notch orv oove 33 rides over they flange orl bead 33', which is arranged in such concentri relation with the path of travel of the blade or vane, that it will serve to maintain the blade in operative bearing-relation with the circular wall of the meter casing 25. The ends of the retaining bead or flange 33 are beveled or reduced somewhat in' thickness to afford a camming action and facilitate the engage-f retraction under excessive back., pressure,

throu hout its `operative stroke from the inlet orifice 26 to the outlet orifice 27. It will ,"be obvious that as the ,rotorf 28 advances, the

s ace intermediate the rotor 28 and wall of t e meter casing immediately in the rear of the blade or vane 29 willbe filled with the commodity under pressure of the feeding screws 7. Th1s space will continue to receive such commodity until the blade approaches the outlet orifice 27, at which time the opposite blade 29 is in position to pass the intake orifice 26, and by itsadvance force the charge received within the casing 25, forwardly toward the outlet 27. At each operation this vcharged space is completely filled under uniform pressure. The charge capacity of this space being known, a predetermined quantity of the commodity may be delivered by limiting the operation of the meter to a predetermined number of rotations of the rotor.

In order to regulate the discharge of commodity by limiting the periodic operation of the apparatus to a prescribed number of rotations of the meter, there is provided a timing mechanism or regulator operating in unison with the motor.17, but adapted to open the motor circuit when a predetermined number of revolutions of the meter has been effected. While such regulator might be located in close proximity tot-he meter, as in our prior application referred to, or closely associated with the motor if so desired, it has been in the present instance located on top of the apparatus and is driven from the power shaft 14. vTo this end, the jack shaftv 20, which is mounted in suitable bearings on anextension or shelf 34, projecting from the top frame of the reservoir or container 1, carries a worm 36, meshing with a worm wheel 37, forming the initial element of .theregulator. This worm wheel 37 ismounted for rotation upon a vertically disposed shaft orl stud 438, carried by an oscillatory arm 39, pivoted at 40 on top of the shelf like projection 34, of the frame of the apparatus.-

The oscillatory arm 39, isprovided with lateraly ears to accommodate an arcuate slot 41, through which engages a clamp screw 42.

The adjustability of the swlnging arm 39, which may be engaged in different positionsV by the clamp screw 42, is to accommodate worm the apparatus to commodities of different .65 densities. For instance, if it is desired to deliver at each cycle of' operation, one poundofy a heavy grease, a smaller worm gear may` be required than to deliver one pound of a' light grease. In changing from one char- 65 acter-of commodity to another, a test run segmental wall into one ofthe openings 54,

may be made and accurately weighed to determine whether a longer or shorter cycle l of operation is necessary to. feed the required quantity. The worm gear 37 rotates loosely upon the stud 38, and is provided with an upwardly directed hub portion 43, within the hub 44 of a housing 45stationarily supported upon the apparatus the wall of which forms one terminal of a make and break switch in the motor controlcircuit. The hub 43. of the worm gear 37 is insulated from the housing 45, by an interposed sleeve 46 ofy .insulating material. The wheel 37 isl further preferablyv recessed for a collar 48, of insulating material, such as fiber, upon which the end of the hub 44 abuts. Surrounding the stud 38, immediately above the hub 43 of the worm gear, is a fiber disc or collar 49, operatively engaged with the worm gear 37, by means of a stud. or pin 50, and in turn engaged .with a rotating arm 51, by means of a second stud or pin 52. A disc of fiber or insulating material 53 is located in the bottom of the housing 45, beneath the arm 51. The construction is such that the housing is entirely insulated from the arm 51, or any of its vconnecting parts. The housing 45 is held stationary, by any suitable connection, 45 with'the frame ofthe apparatus, while the arm 51 rotates within such housing, in unison with the worm gear 37, but normally insulated from the housing.

The circular wall of the housing 45 is formed with a series of spaced openings Aor notches 54, affording there between a seriesl 1.00 l

of spaced contact segments which are elect-ricallyA connected into the' control circuit. There-may be only one of these openings or notches, in which event, the regulator arm 51 will make a completerotation at each cycle 135 of operation, or as shown in the drawings, there may be a plurality of notches or recesses 54 affording a series of contact segments with which the motor controlled circuit is successively closed.

The rotatin larm 51 carries a spring actuated contact nger 55, pivotedv at 56 to said arm 51 with -which it is also electrically connected, and .normally actuated into wiping, engagement with the segment formed by the 115 notched wall of the housing 45 bythe spring 57. This finger 55 forms one terminal of a make and break switch the opposite terminall of which may be any'one of the segments of the wall housing 45 is formed by the notches Vor recesses 54. The finger 55 is also provided with a stop stud 58 engaging a projection or stud 59, to limit the throw of the finger, 55 under the iniuence of the spring 57 when such finger passes off ofthe arcuate wall of the housing into one of the notches 54. This A wipe finger 55 by its engagement with the arcuate wall ofthe housing 45, completes the motor circuit and when it passes olf such its sudden advance movement under the in- 4iuence of the spring serves to quickly break rotating arm 51 is held in engagement with the driving gear by means of a tension spring 51, abutting at its lower end upon the arm 51, and at its yupper end seated within an overhanging cap 60. The regulator or timer is preferably covered by a disc 61 of glass or other transparent material held in place by a flanged collar 62. This regulator is included in the motor circuit, by grounding one side of the motor upon the frame of the apparatus, or otherwise connecting it electrically with the rotating arm 51. One side of the current supply circuit is then connected with the motor and the other side with the housing 45, so that a circuit is completed by the wiping contact with the finger 55, with the segmental wall of the housing as the arm 51 is rotated. This connection will be clear from an examination of Fig. 5, wherein the electrical circuits are shown. It is obvious that so long as the wipe finger is in engagement with the segmental wall 'of the housing 45, current will be supplied to the motor and the apparatus will continue in operation. I-Iowever, as 4the wipe finger approaches one of the notches 54, and is actuated by its spring to break the electrical circuit, the motor will be brought to rest. In order to initiate the operation of the apparatus, it is necessary to bridge this open contact between the wipe finger 55, and the housing 45. This in the present instance is effected by means of a push button upon the discharge nozzle of the conduit 23. At the extremity of the conduit there is provided a nozzle 63, preferably having therein a cut-off valve 64. Located on the side of the nozzle 63, adjacent to the cutoff valve is an electrical push button 65, from which conductor wires lead, preferably through the discharge conduit to the apparatus and thence across the gap afforded by Y the wipe finger 55, and the contact wall of the housing 45. This connection is shownv diagrammaticall in Fig. 5, where it is obe vious that by c osing the push button 65,

momentarily, the motor will be actuated to advance ythe wipe finger until it engages "the'segmental wall of the housing- 45whereupon the push button 65 may be released, and

55 `the motor will continue its operation, until the next notch or opening 54 is engaged by the contact nger 55.- v

The purpose of mounting thisl `,control switch 65 upon the discharge nozzle, is toenable the apparatus to be controlled by a single operator. The dicharge conduit 23, may be of any suitable length, and 'whatever its length may be, the operator who holds the .discharge nozzle and therefore observesthe flow4 of the commodity, hasabsolute control of the `starting of the apparatus. The apparatus when once started will continue its operation until the predetermined quantity is delivered. This quantity is preferably predetermined in pound or pint lots. That is to say, thel apparatus is so designed and the gear ratios of the worm drives 36 and 37, so I proportioned that one pound or one pint of commodity will be delivered while the arm 51 rotates to carry its wipe finger 55 from one opening 54 to the next one.

As a matter of safety, the valve 63, uponv provided witha lid 66 having an upstanding f hollow standard 67, provided with a lateral access opening 68, into which the end of the nozzle may be inserted. when not in use. To this end the nozzle is provided with a pin or finger 69, by which it may be operatively engaged in the opening 68, by hanging it therein.

From the above description it w'ill be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without'departing fromthe principle involved or sacrificing any of its advantages. i

While in order to comply with the patent statute the invention has been-described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific details shown, but that the means and construction herein disclosed comprises the preferred form of severalmodes of putting the invention into effect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appendedclaims, v
