CAN-FILLING MACHINE.

Application filed January 23, 1922.

To all whom t may may conce/rfa:

Be it known that l, Josnrrr C. BRUNO, a citizen ot the United States, residing` at utalo, in the County ot Eric and State ot' New York, have invented certain new and useful improvements in Can-Filling Machines, of which the following is a speci- `tication. y

My invention relates to improvements in can-iilling machines, and more particularly to that type ot machine in which cans are tilled according to weight, each can receiving a. predetermined weight oit material.

One or" the objects ot my invention is the provision of an improvedy candilling inachine which is positive in action and highly sensitive so that when 'the material being lilled into a can or other receptacle reaches the predetermined weight., the iiow ot the materia-l will be mechanically shutsott' without variation in weight in the various cans lle'd.

Another object ot my invention is to provide a can-lling device ot this kind 'from which the discharge ot the material with which cans or other receptacles are to be tilled may loe controlled either by hand or toot manipulation.

A turther object ot my invention is the lprovision ot a machine ot' this kind of comparatively tew parts, and which can he easily cleaned to remove any material adhering to the internal surfaces ot the walls forming the conduits, chambers, or passages through which the material is passed.

`With the simyo-mentioned and other objects in view. the invention consists in the .novelv features ot'con'struction, and in the arrangement and combination ot parts and devices to be hereinafter described and more particularly pointed out in the suhioined claims.

Reference heing now had to the drawings in detail, like numerals reifer to like parts in the several ligures.

rFhe reference numeral 2G designates the main support or trame ot the machine, which comprises a base 27 cast to any desired torr and ot sutlicicnt area to provide a solid 'toundation for all parts ot the machine carried by the upright 2S et said lill) support or frame. The base is formed with an upstanding socket 29 into which the lower end of the upright 28 is seated, and this upright preferably has its lower portion cylindrical, as at 80, and its upper portion square, as at 31.

llVhile I have shown and prefer a solid upright with a` cylindrical lower portion and a non-cylindrical upper portion on account of certain advantages gained thereby, it is to be understood that the upright may be formed hollow and if desired be differently shaped.

Projecting forward from the cylindrical portion of the upright 2S is what l term a scale-supporting bracket 32 and projecting forward from the square or non-cylin drical portion of said upright. is what I term a `valve-supporting racket 33. Each of these brackets comprises two exact counterparts 34, each provided near each end with a transverse depression 35 on its inner surface, the depression in the scale-supporting bracket being semi-circular while .hose in the valve-supporting bracket are V- shaped. The two counterparts or members of the scale-supporting bracket are positioned at opposite sides of the cylindrical portion of the upright 28 with said upright entering both semi-circular depressions at the inner end of the bracket, and passing through the inner extremities ofthe two counterparts or members 34 of said bracket is a clamping bolt 36.

A stud 37 depending from a scale frame 38 is fastened in the outer end of the scale-supporting bracket 32, the two semi-circular depressions at the outer ends of the two members 34 thereof forming a circular opening to receive said stud, and a clamping bolt 39 is passed through the outer extremities of said members and thus clamps the scale frame in said bracket. By sccurely tighteningT the nuts of the clamping bolts 3G and 39, the scale-supporting bracket will be securely fastened to the upright 28 and the scale frame will be firmly clamped in position within said bracket.

The scale frame comprises a longitudinal member 40 and a transverse member 4l midlength thereof, said transverse member extending from opposite sides of the longin tudin al member and having upstanding lugs 42 provided with V-shaped depressions 43 in their upper faces. This scale frame is preferably cast and at the points of said depressions has steel or other hardened inserts 44 into which the pointed inner ends of the depressions extend. As a convenient means of providing hardened bearing points at the inner ends of said depressions, circular openings are bored through the upsta-nding lugs 42 and into these openings steel plugs are inserted, the ends of said plugs being iiush with the outer anl inner surfaces of said lugs. The V-shaped depressions are then machined into the lugs with the pointed lower ends of the depressions formed in said steel plugs. At the outer extremities of the longitudinal member of said scale frame, vertical openings 45 are formed into which supporting rods 46 are fastened by means of set screws 47 which are threaded through the ends of said longitudinal member and bear against said rod. rllhe lower ends of said supporting rods are provided or formed with enlargements 48 which rest upon the base 27 of the support or frame or upon the floor. Thus the scale frame is supported at its ends and eenl trally between its ends.

49 designates the scale beam which has a central transverse member 50 and end mem bers 51, 52, connected with said central transverse member by arms 53. Passing transversely through said central transverse member and fastened therein by a set screw 54 is a fulcrum member 55 having opposite ends provided with downwardly directed V- shaped portions 56 forn'iing knife edges which bear against the hardened plugs or inserts 44 of the upstandiug lugs 42. Each of the end members 5], 52 has a fulcrum member 57 fastened therein, and opposite ends of each of these members is provided with upwardly-directed V-shaped portions 58 forming knife-edge fulcrum points.

59 designates a platform frame which comprises a hub portion (50 and four diagonally-disposed or radial arms Gl extendlng outwardly from said hub portion. The outer end of each of these arms is provided with a vertical opening and through these openings, platform supporting rods G2 depending from a can-supporting platform 63 are passed, said rods 62 being adjustable within said openings and being held in any adjusted position by means of set screws G4.

Extending outwardly from the hub portion of the platform frame and connect ing the diagonally-disposed arms (il in pairs are two bearing members ($5 provided on their under sides with V-shaped depressions 66 extending into steel or other hardened inserts 67, which are similar in form and applied in the same manner as the steel inserts 44 in the scale frame. The upwardly directed V-shaped portions 58 of the fulcrum member 57 serve as fulcrums for said platform frame, the knife edge bearings of said fulerum member being in contact with the pointed inner ends of said Vshaped depressions.

A U-shaped casting- 68 is secured to the under side of the platform frame 59 and may be said to form part thereof. This casting has ears 69 through which bolts 70 are passed that take into the under side of the hub portion G0 of said platform frame. The vertical members of the U-shaped por- Lil uns!

tions provided with notches 71 into which the ends of the fulcruni members 57 extend. the walls of said notches being, however, out of Contact with said fulcrum member so that the platform frame and the supported platform are carried solely by the knife edged portions of the fulcrum member 57.

Threaded into the U-shaped casting 68 is a rod 72 which has a nut 78 applied thereto bearing against the under side of said casting. This rod may be adjusted within the castinO' and retained in any adjusted position by said nut,

74 designates a weight table having a central depending boss 75 into which is threaded a screw stud 7 6 projecting upwardly from a cavity 77 formed in a table support 78 having depending` lugs79.provided on their under sides with V-sliaped depressions 80 extending into steel or other hardened inserts 81 which are also similar in form and applied in the same manner as the steel inserts 44 in the scale frame. A U-shaped casting 82 is secured to the under side of the table support 78 and may be said to form part thereof. rlhis casting has ears 83 through which bolts 84 are passed that take into the under side of the table support. The vertical members of the U-shaped casting 82 are provided at their upper ends with notches 85 into which the ends of the cti-operating fulcrun'i member 57 extend. Like the walls of. the notches 71, the walls of these notches are also out of contactwith said fulcruinmember so that the table support, like the platform support. is carried solely by the knife edge portion ofthe fulcrum member.

Threaded into the U-shaped casting 82 is a rod 86 which has a nut 87 applied thereto, said nut bearing against the-under side of said casting. The rod 86 is therefore ad,- justable within the casting and may be retained in any adjusted position by said nut..

The scale frame 38 is provided at opposite ends and adjacent the vertical openings 45 with comparatively large openings 8S through which the rods 72 and 86 are passed, the lower ends of said rods being bifurcated, as at 89, to receive the ends of a balance lever 90, said ends being pivotally secured within the biturcated ends of said rod and said balance lever being pivotally.

fastened within the lower end of the stud 87 of the scale frame 38, as at 91. The

weight table 74 is easily removable from the` table support 78, as it 1s simply necessary to unscrew the` same from the screw stud 76. This will permit shot 92 or other line balancing material to be placed within the cavity 77 of the table support and thus assure exact balance of the scale beam.

To prevent accidental removal ot' the scale frame from its bearings. angle-shaped retainers 93 are fastenedy to the outer side third bracket 9G which extendsl `rearwardly from the support 2G.- The bracket 96 supports a float-controlled tank 97'having an inlet pipe 98 through which is passed the liquid to be lilled into cans or other containers from said tank, this liquid being supplied from a suitable storage tank (not shown) preferably arranged in a higher plane than the tank 97 so that the liquid will be fed into saidl tank 97 by gravity.

Connectingv the combined valve and niechanism casing with the float-controlled tank 97 is a supply pipe 99 which includes flanged coupling or other suitable litting 100 riveted or otherwise'secured tothe bottom of the wall of the tank 97. as at 101,

and into which said supply pipe is threaded:

Arranged in this supply pipe is a union 102 by means of which the casing 95 can be conveniently disconnected from the tank 97 when it is desiredto clean said casing. The supply pipe 99 is provided with a hand valve 103 whereby the flow of the liquid from the heat-controlled tank may be shut off.

As clearly shown in Figs. 21 and 25, the float-controlled tank 97 has its inlet pipe 98 connected to one of the walls thereof b v atlange fitting 104 which is riveted or otherwise fastened to said wall, and threaded into said fitting from the interior of the tank is a' valve fitting 1.05 which comprises a cylindrical open-ended member 100 ternally threaded along a portion of-its length 'for entrance into the tlange coupling or other {itting 104 and being provided adjacent said e-Xternally-threaded portion with al hexagonal or other wrench--applying enlargement 107 b v means of which the valve fitting may be securely fastened in place. Said cylindrical open-ended nieniber has a aised valve seat 108 at its inner end and the hexagonal enlargement 107 is provided with an inwardly-directed arm 109 having an upstanding` terminal 110 to which a valvecontrolling lever 111 is pivotally secured, said lever having an upwardly and outwardly-curved projection or toe 112 at its pivoted end which bears against a flat valve 113 pivotally secured to the arm 109, as at 114. said valve havinga fiber or other facing 115 adapted to bear against thea'aised valve seat 108. The outer end of said lever is pivotally secured to the lower end of a link 110 having pivotal connection at its upper end with a float 117, said loat being' Lil a hollow box-like member formed of metal and provided centrally with a tube 11S which extends through said box-like niember and projects both upwardly above the upper wall of said member and downwardly below the lower wall thereof, said tube being securely soldered or otherwise secured to said box-like member to render the interior of said member air-tight.

Extending transversely through the lupper projecting end of the tube 11S are small tubes 119 which' are alined and soldered or otherwise fastened at their outer ends in openings formed in said tube 118, as best shown in Fig. 15. The alined tubes 119 are separated at their inner ends and between the same the upper end of the link 116 is adapted to be positioned, said link having a plurality of spaced pivot holes 120, any one of which is adapted to be brought into registration with said small tubes. Through said tubes 119 and the registering pivot hole of said link, a pivot pin 121 is passed, said pin projecting beyond the outer ends of said tubes 119 and having cotter pins 122 passed therethrough to hold the parts in position. The float is therefore adjustable on the link 116, as it is simply necessary, in order to adjust the same, to remove the pivot pin 121 and lower or raise the float, as the case may be, to bring a different pivot hole in the link 116 into registration with the small alined tubes 119. These tubes provide extended bearings for the pivot pin 121 and also maintain the link 116 in outward position. For convenience in adjusting the float on the link I have provided means for retaining the link in vertical position, and for this purpose have riveted to opposite sides of the link, flat springs 123, which normally have their free lower ends curved outwardly, and said free lower ends are provided with pivot holes 124 which register with a pivot hole 125 'in the link 116. The lower end of said link with the springs pressed inwardly against the same are inserted within the bifurcated portion of a coupling or other fitting 126 secured to thc outer end of the valve controlling lever 111, a pivot pin 127 being passed through said fitting and through the springs and link. The springs tend to exert pressure outwardly against the inner surfaces of the bifurcated portion of said fitting and thus retain the link in any position it may be placed` yet allow free action of the lever when the float secured to the upper end of the link rises or lowers. F or convenience in adjusting the float on the link, the upper end of the float-controlled tank 97 is open and thereforel access may be easily had to the pivot by means of which the float is connected to the link. In order to prevent dust and dirt entering the float-controlled chamber, the upper open end thereof is closed with a cover 128.

When starting the machine in operation, the weight of the float will cause it to lower, with the result that the valve'113 will be open. Now, when feeding liquid into the float-controlled chamber, the level thereof will gradually rise until it reaches a height sufficient to support the float, whereupon said float will gradually rise with the rising liquid, and when it reaches a predetermined high level in accordance with the adjustment of the float on the link 116, the flat valve 113 will close against the valve seat` 10S, thereby shutting oit' the flow of liquid into said tank. It is, however, apparent that the liquid is free to flow into the combined valve and mechanism casing 95, except when the hand valve 103 is closed. The discharge of liquid from the combined valve and mechanism casing will be controlled by mechanism to be presently described. Y

Then the level of the liquid within said tank lowers, the fioat will descend and cause the valve-controlling lever 111 to swing on its pivot, with the result that the flat valve 113 will swing into open position, by reason of the pressure of the liquid behind the valve overcoming that of the liquid within the tank, the open position of the valve being indicated by dotted lines in F ig. 21.

The float-controlled tank 97, as stated, is 'i supported by the upright 28, but as the point of attachment of said tank to said upright is at the front of the tank, I provide additional supports 129 at each side, these additional supports being in the form of upright bars secured at their lower ends to upstanding lugs 130 on the base 27 and passing through loops 131 on the bracket 96, said loops having set screws 132 by means of which the float-controlled tank 97 may be secured at any desired point along said additional supports. In this manner the weight of the float-controlled tank and its contents is not solely supported by the upright which would cause a slight bending of Isaid upright and consequently create more or less binding of certain of the movingparts of the machine.

The combined valve` and mechanism casing 95 has a horizontal conduit 133, to one end of which the supply pipe 99 is connected, the other end of said horizontal conduit opening into a vertical conduit 184: projecting a short distance beneath said horizontal conduit, as at 135, and a considerable distance thereabove, as at 136. The upper end of said vertical conduit is closed, while the lower end thereof is open and internally threaded. 'I`he square stud 94, hereinbefore referred to, is preferably arranged at the inlet end of the casing 95, as best shown in Fig. 1l, and at said end the horizontal conduit 133 is substantially spherical in formation with an opening 137 at one side thereof which is internally threaded to receive a shaft bearing lill) llt) 13S forming aart oit a stutling bonv 135. In said shaft bearing,'a rock shaft 140 is ar` ranged tor' rocking movement, said rock shaft extending inwardly into the spherical portion ot said horizontal conduit and outwardly through said stutllng box. Said roch shaft 140 is provided with an annular groove 141 into which the end of a set screw 142 is entered, said set screw being passed through the wall ot' said shatt bearing and permitting rocking movement ot said shatt within its bearing but preifenting lengthwise movement thereof.

Fastened to the inner end ot the rock shaft 14() within said horizontal conduit is one end ot a valve-actuating lever 143 terminating at its other end within the vertical conduit 134 in the 'torni ot a hook 144. Threaded into the lower end of the vertical conduit 184 is a combined nozzle and valveseat 145, the exterior ot which has a polygonal flange 146 formed thereon so that it can be easily removed and replaced with another of smaller or larger' size.y as may be found desirable. The portion oit' said nozzle below said flange is adapted to be shaped to conveniently enter the lilling openings ot the cans to be lilled, depending more or less on the size or' the openingl within the can and in some cases on the Jformation of said opening.

For purposes of illustration 1 have shown a can in dotted lines in Fig. 1, as at 147, but in this instance the lower end of the nozzle terminates above the filling opening ot the can7 as such a position may be found desirable when filling cans with certain kinds ot material.

The interiork diameter of the nozzle at its lowerl end is of a size that it will eed into the cans to be lilled without` any portion ot the liquid coming in contact with the tops ot' the can or other receptacle.

lithin the vertical conduit 134, with which may be included the interior o1 the combined nozzle and valve seat 145, is a shut-ott or `tlow-controlling valve 148 adapted for vertical movement, said valve being shaped to conform to the interior ot the nozzle so that when seated against the inner surface ot the nozzle it will ettectually close the same and prevent feeding ot the liquid therethrough. This valve is provided with a socket 149 at its upper. end into which is loosely litted the lower end or a stud 150, said stud being pivotally secured within said socket by a pivot pin 151 so that the valve will be able to adjust itselt to its seat within said nozzle. The upper end ot said stud is threaded into a loop 152 which has the lower end ot' a rod 153 threaded into its upper end, said vrod extending upwardly into the vertical conduit 184 and having a weight 154 secured thereto. That portion above the horizontal conduit may be termed an air chamber and in this an' chamber the ,weight 154 and rod 153 are positioned.

rl`he inner walls of the loop 152 are rounded, as at 155, and into the opening oit said loop the hook end 144 ot the valve actuating lever 143 is positioned.

Controlling mechanism is arranged between Ythe outer end ot the rock shait 146 a nd the weight table T4 ot' the scale, and ttor the purpose of properly supporting-this controlling mechanism 1 secure a hanger 156 to the shaft-bearing 138, which bearing may be said to t'orm parl o't the combined valve and mechanism casing 95. This hanger comprises a hub 157 which has an axial opening 15S therein and a pair orI spaced lugs 159 extending' upwardly therc'trom; said hub being split trom said opening outwardly to the space between said lues so as to torni a contractable hub and 'tor this purpose a clamping bolt 160 is passed through one of said lugs and threaded into the other. rlhis arrangement permits the hanger 156 to be adjusted lengthwise on the shat't bearing 13S.

Projecting Ytrom said hul.) 154 are two arms 161, 162 arranged in diverging lines. These arms have at their outer or lower ends, laterally-extending bosses 163, 164, respectively.

Secured to the top of the combined valve and mechanism casing is a combined guide and stop member 165, which projects forwardly, and at its front end has a guide boss 166 through which a vertically-movable operating rod 167 is passed, said rod forming part ot 'foot-operating mechanism and having a litter or actuating member 168 adjustable.'thereon. The lower end of said rod passes through a guide bracket 169 secured. to the base 2.7.and at said lower end is threaded into a forked fitting 170 pivotally connected to the inner end of a toot lever 171, said toot lever' being pivotally secured at a point between its ends between upstanding lugs 172 and having a treadle 173 at its outer end. Between the torked litting 170 and the portion ot the guide bracket 169 through which said operating rod 167 passes, a spiral spring 174 is arranged, said spring surrounding said rod and bearing with its upper end against said guide bracket and with its lower end against said fitting to keep the inner end of said toot lever 171 depressed and the operating rod 167 lowered.

The lifter or actuator member 163 com prises a body portion 175 having a vertical opening' through which the operating rod 16T is passed, said body portion being split from said opening to one end of said bodjv portion, and through this split part a clampingbolt 17 6 is passed which serves to tasten the lifter or actuator member' lirmly to aid lit) rod at any point desired. Fastened to said body portion is an upwardly-swinging trip dog 177 having an upwardly-and-outwardly inclined surface 178 and a substantially flat horizontal surface 179 against which one end of a spring 180 bears, which spring is secured to the body portion of said lifter or actuator member, as at 181, and serves to retain said dog in its lowered posi tion.

Fastened to the outer end of the rock shaft 140 is a detent arm 182, from which a hand operating lever 183 extends, said lever extending from said arm at a point adjacent the attachment of said arm to said rock shaft. Said hand operating lever 183 has an outwardly-extending trip stud 184 adjustably secured thereto, and for this purpose said lever is provided with a longitudinal slot 185 in which said stud is movably secured in any approved manner. rI he outer or actuating end of said trip stud is substantially V-shape in cross section, with the edge or point thereof directed toward said detent arm. The spring-retained trip dog 177 is adapted to engage the under side of the trip stud 184 when the operating rod 167 is elevated by the foot iever 171. This trip dog is adapted to elevate the hand operating lever 183 and after elevating the same to a certain angle, namely that shown in full lines in Fig. 3, said trip dog is adapted to pass beyond and above said trip stud.

lVhen releasing the foot lever 171, the spiral spring 174 causes the operating rod 167 to lower, whereupon the upwardlyand outwardly inclined or beveled surface 178 of the trip dog will engage the upper inclined 'tace of the trip stud 184 and be swung on its pivo-t so that it will pass idly over the pointed edge of said trip stud and heneath the same without in any manner effecting the hand operating lever 183,

It is apparent therefore from the foregoing, that the mechanism may be actuated either by hand or by foot, and that the foot operating mechanism causes operation of the niaehine through the medium of the hand operating lever 183; the parts, however. being so arranged that said hand operating lever may be operated without causing movement of the -foot operating mechanism, or any part thereof.

t The combined guide and stop member 165 1s provided with an adjustable stop bolt 186 which is threaded upwardly through the outer end of Said guide and stop member at one side of the `guide boss 166 thereofI and retained in any adjusted position b v means of a jamb nut 187, which is threaded onto said bolt and bears against the under side of said guide and stop member. The head of said bolt 186 is adapted to he engaged hv the hand operating lever 183 and limits the upward movement thereof, and in order that the spring-pressed trip dog 177 will pass upward y beyond the trip stud 184 at the instant that the hand operating lever engages the stop bolt 186, said bolt is adjusted to the exact point allowing such action by moving it along the longitudinal slot 185.

The detent arm 182 is provided at its lower end with an elongated detent shoe 188 having a hardened contact portion 189 on its under side at one end thereof. 190 designates a supporting member formed of sheet metal and having a vertically-disposed portion 191 and a horizontally-disposed portion 192 extending forwardly from the lower edge of said vertically-disposed portion, said vertically-disposed portion having a forwardly-extending stop lng 193 thereon and at opposite ends it is provided with bolt holes 194, 195. Through the bolt hole 194 a bolt 196 is passed, which is threaded into the boss 163, thus securely fastening one end of said supporting member to the hanger 156. A bolt 197 is threaded into the other boss 164 and surrounding it is a spacing sleeve 198, said bolt 197 having an inwardly-facing shoulder 199 which bears against the outer end of Said spacing sleeve. while the inner end thereof bears against the outer face of the vertically-disposed portion 191 of the supporting member 190.

200 designates a detent lever pivotally secured at one end by said bolt 197, said lever being retained in position on the enlarged portion of said bolt between the outer end of said spacing sleeve 198 and the head of said bolt. Said detent lever extends from its pivotal point directly over the horizontally-disposed portion 192 of the supporting member 190 and is held in elevated position by a spring 201 secured with one end to said horizontally-disposed portion and bearing with its other or free end against the under side of said lever.

The detent lever comprises what may be termed a hub portion 202, which is provided with a threaded bore 203 into which one end of a lengthening rod 204 is threaded, said rod having its other end threaded into the outer or main portion 205 of said lever. Bearing against what I have termed the hub portion ot.' the lever is a detent platr 206, which has an upwardly l'nfojecting portion and which is held against said hub portion by a nut 207 threaded onto the lengthening rod 204. said detent plate having a beveled edge 208 and the upwardly projecting portion thereof being adapted to engage the hardened contact portion 189 of the detent shoe 188.

Fastened in a bolt hole 209 in the vertically-disposed portion 191 of the supporting member 190 is a pivot bolt 210, which has a reduced threaded end providing a Shoulder adapted to bear against the outer side of said vertically-disposed portion 191, while a nut is threaded onto said reduced portion and bears aga-inst the inner side of said vertically-disposed portion 191 so as to lirmly secure said bolt in place. Between the head of said bolt and a wasl'ier 211 which surrounds said bolt and bears against the outer side of said vertically-disposed portion 191 is arranged rfor swinging movement a trip lever 212, which is partly in the forni of a bar 213 of rectangular formation and partly in the form of al rod 21a which is threaded into said bar and extends laterally therefrom. The rod portion of said trip lever is in contact with the saddle-like bearing;` member 215 of a vertically-disposed trip rod 216. `Said trip rod is adiustably secured tothe table support .78 of the scale, as at 217 so that it may loe adjusted vertically to assure proper actuation of the trip lever 212.

The trip lever has the pivot holt 210 passed through its rectangular portion near the secured end'of therod 21-1 forming part thereof and it is closer to one end than the other so that the trip lever may be said to have a short arm and a long` arm.

llt is to be noted that the outer end of the detent lever 200 is provided with an adjustable bolt 218, the head of which is provided with a rounded contact portion 219, which bears against the under side of a contact plate or arm 220 extending' forwardly from the short arm of said trip lever. Said bolt is adjustably threaded through the detent lever 200 and has a unt 221 threaded thereon which bears against the under side of said detent lever and retains the bolt at the desired adjustment. The upward movenent of the trip rod 216 is therefore imparted tothe detent lever 200 through the medium ofthe trip lever 212, causing said detent Vlever to be depressed against the action ofthe spring` 201. lllhen, therefore, the detent lever is depressed the pointed upper end of the detent plate 206 will become disengaged from the detent shoe 188, which will permit the shut-off of flow-controlling valve 141-8 to close aga-.inst its seat within the nozzle 1115, due to the fact that the weight 154 within the air chamber of the casingwill act to depress the valve-actnatinglever 143 and cause the rock shaft 1510 to roch; said shaft in turn swinging` the detent arm 182 to the right in l? 1. such action of said arm being assured by reason of the fact that on the hand operatiina` lever 188 a weight 222 is adjust-ably held, said weight being movable toward and from the detent arm and being,` retained in any adjusted position by a set screw 228, or otherwise. The degree of contact or bite which the detent plate 206 takes vagainstthe detent shoe may be roverned toa nicety hy"adjiustiiug` the bolt 218.

By means of the provision made for shortening or lengthening the detent lever, and by reason of the adjustment of the bolt 218 in said lever, a. very sensitive action is secured between the detent arm,and more particularly the shoe thereof, and the detentlever when the trip lever is actuated by the trip rod 216 and assurance is had that every can being' iilled will have the exact weight of all othc.' cans fille-il with the same material.

The hand operatingl lever 188 bears against the adjustable stop bolt 186 when in elevated position, which holt limits the opening' movement of the shut-ofi' or flowcontrollingl ,f'alve 1- i and also limits the 'ange of movement of the detent arm 182 in one direction. lilith a supply of liquid stored in the doa-controlled tank 9'? the liquid is pas-'setL through the combined valve and mechanism casing' 95 of the machine and when the lef'el of the liquid lowers within the 'tank 9i' the valve 118 therein will open and i uit an additional quantity of liquid to l tank from the inlet pipe (L until the proper level within the tanl; is again reached. which causes said valve to be closed by the lioat 11'? and parts between the same and said valve. ln this manner the liquid is maintained at a constant level in the float-controlled tank 9'? and the pressure of the liquid passing` through the coinbined valve and mechanism casing' 95 is constant at all times. lfilhen the shut-oli or flow-controllingl valve 148 is in closed position within the nozzle 115, the flow of the liquid is stopped. lllheu, however, the inachine is not in use the hand valve 108 is closed. 1When the hand valve 108 is opened and the shut-oil' or dow-controlling' lvalve 141-8 is closed, the machine is in condition for operation.

The operation of the device is as follows:

A can or other receptacle to be filled is placed upon the platform 623 of the scale, this platform having' heen previously udj usted vertically to bring the iilling opening;l of the can or receptacle thereon directly underneath and in close proximity to the discharge opening of the nozzle lil-. Assuming' the can to hold a pound of liquid when filled, a one pound weight is placed upon the weight table of the scale. with the shutoilI or flow-controlling valve l-ill closed against its seat within the nozzle the hand oiierating lever 183 is in the position shown in dotted lines in l? 5, the detent arm 182 with its shoe. the detent lever 200. and the trip lever 212 Being' also in the positions shown in dotted lines in said ligure. `When a can or other receptacle placed on the platform of the scale and a proper eountervfieht placed upon the weight table il, the hand operating lever is swung' upwardly by grasping the outer end of the same or by actuating the same through the medium of the foot lever 171. This will cause the detent arm 182 to swing fiom the position shown in dotted lines in Fig. 3 to that shown in full lines so as to bring` the outer end of the shoe thereof in contact with the detent plate 206, thereby retaining said hand operating lever and detent arm in the position shown in full lines in Fig. 3. Due to the detent arm being secured to the rock shaft 140, the valve actuating lever 143 Within the casing 95 will be elevated from the position shown in full lines, thereby elevating the weight 154 and unseating the shut-off or flow-con: trolling valve 148 so that a free escape for the liquid is provided through the nozzle 145. The liquid thereupon enters the can or receptacle placed upon the platform 63 of the scale and the weight thereof gradually depresses said platform and elevates the weight table 7 4 with the counterweight thereon, thereby causing the trip rod 216 to be elevated, which in turn swings the trip lever 212 on its pivot and causes depression of the short arm of said trip lever, the contact plate or arm 220 on said trip lever being at all times in contact with the adjustable bolt 218, therefore causing depression of the detent lever 200 so as to disengage the detent plate 206 thereof from the end of the detent shoe 188 at the lower end of the detent arm 182. This action releases the rock shaft 140 and the weight 154 surmounting the shut-olf or flow-controlling valve 148 and causes said valve and the valve actuating lever 143 connected with said valve 'to be depressed, thereby shutting oli? all liquid from the platform.

In order to position the cans or other receptacles to be filled in proper position underneath the nozzle 145, a can or receptacle guide-device is provided. This is formed of a piece of wire or rod material doubled inidlength upon itself, as at 224,` Fig. (l, to provide two parallel spaced parts 225, which have their outer ends inclined outwardly, as at 220, thus forming a flaring guide. for the cans or receptacles. This guide is placed upon the can-receiving platform 0?, which is provided with a number of openings 22T arranged along one or more marginal portions thereof. A thumb screw Yacts against the parallel parts 225, either directly or through a retainer piece, and is threaded into any one of the openings 227, said thumb screw passing downwardly between said parallel parts and clamping the same in any position. lith the thumb screw passed between the parallel parts and loosened, the guide device is free to be swung into any position, using said .thumb Screw as a pivot or fulcrum point, or it maj.'v

be moved inwardly along a straight line so as to bring the thumb screw closer to the flaring guide portion of the device, or farther from the same, as may be desired.

An arrangement such as described permits adjustment of the guide device laterally or longitudinally, or an adjustment may be effected in which a combination of both lateral and longitudinal movement is included. Moreover, the flaring guide portion of the device may be positioned at any point on the platform, due to the provision made for securing the guide member at different points on the platform. Thus, a receptacle either square, round, or oval of any cross-sectional measurements may be positioned directly under the nozzle 145 of the machine so that said nozzle will fit into or be positioned directly over the lling opening of the receptacle, regardless of the position on the can of said filling opening. After once adjusting the guide to the filling opening of any can, all cans of the same size and shape can be quickly placed upon the platform and guide to position by moving them against the fia-ring members 226 of the guide with absolute assurance that the filling opening will be directly underneath the nozzle and no loss of material result from the operation of the machine.

The detent mechanism may be referred to as holding or latching means, since it holds and latches the shut-olf or flow-controlling valve and associated parts in open positions.

In its broadest sense, certain parts of my improved machine may be said to constitute controlling mechanism, such mechanism including trip mechanism. detent mechanism, and parts between said detent mechanism and the shut-oliii or iiow-controlling valve 148. The term coperating mechanism when disassociated from the word foot is intended to mean all parts between the hand operating lever 183 and the shut-olf or flou'- controlling valve 148 or their equivalent, either with said hand operating lever or with foot operating mechanism, or both with hand and foot operating mechanisms` and the term hand operating mechanism in the claims hereto is intended to mean the hand operating lever 188 and parts connecting said lever with the sluit-oill or How-controlling valve 148.
