-The material measuring', and delivering mechanismhas several novelifeatures forming lthe subject :of copending application Serial No; 197,809 led :October 22, 1917, and application Serial Number-300,993, filed 28 rotatable .by and coaxially .with 4the vshaft 11, a bearing plate 26.'securedto the stationary element: 57 and having therein a tapered bore 43, formed eccentrically of the shaft I supply tank 6 and arranged fin an annulus formed lintegral and coact withthe upper 11,- andan annular series of seven measuring cylinders 7 secured tothe peripheryaof :p1-'125' 7 and flo from the machine.

jacent stationary cam tracks, and

thetank :,eaopas 29 located in the central recess 58A of the plate 28 are pivoted at corresponding ends to the plate 28 and at their op osite correspending ends to the bottom o the tank 6, by means of pivot pins 45, see Figs. 1, 3 and 6. The eccentricity of the opening 46 in the bottom of the tank 6 relatively to the recess 58 in the plate 26, is such that during simultaneous rotation of the tank 6 c linders 7 and late 28 by virtue of the i s 29, the cylin ers 7 are successively laced into communication with the tank 6 t rou h the opening 46 and recess 58, as indicat in Fig. 3. The plate 28 is also provided with an annular series of seven discharge nozzles 56 which are spaced equidistant apart and from the axis of the shaft 11. When the cylinders 7 are in communication with the tank 6, they are cut olf from communication with the nozzles 56, each cylinder 7 being brought successivel into communication with the tank 6 andy with a nozzle 56 as the cylinders plate 28 are relatively gyr'ated. The nozzles 56 are located above and directly 1n line with the cans 19 which are being transpgrted through the machine by the can hooks 4 The element 57 is prevented from rotating by means of the brackets 27 secured to the side frames 17 as shown in Fig. 3, the element 57 being freely vertically removable Vertically adjustably secured to the brackets 27 are lower and upper .cam tracks 13, 24 which extend in roximity to the measurin cylinders 7. .rlhese cam tracks 13, 24 have ubs 52 which are in line with hubs 54 of the brackets 27. The alined hubs 52 54 are relatively adjustably secured to each other by means of stud bolts l53, nuts 55 and adjustln hand wheels 50. Each measuring cyllnder has therein a reciprocable piston 9 provided with a piston rod 42. The upper end of each piston rod 42 is secured to a late 8 to which a guide 12 is also secured. lie guides 12 are arallel to the piston rods 42 and coact wit ide yways 10 formed inte al with the wa s of the cylinders 7. Eac ide 12 has a roller mounted thereon, w ich coacts with the adjacent cam tracks 13,24. As the cylinders 7 revolve, the rollers 25 coact with the adositively raise and lower the pistons `9 within the cylinders 7.

. Within the tank 6 is located a float 2 which rests u on the liquid within the tank and which as a central inlet pipe the upper ex-` tremity of which forms a cut-olf valve adapted to enter an annular recess in the valve seat 5 to automatically cut olf the supply of lluid when a predeterminedhigh level of fluid is established in the tank 6. This automatic cut-of valve is entirely balanced being sensitive and 'tive in action. The bottom of is provided with a filter or screen ing the machine. Such `automatic closing of the valve 34 is effected by the lever 60 pivoted at its medial portion to the frame 17, and having at one end a slot engaging the pin 37 on the stem of the valve 34 and at its opposite end a pin 38 engageable with the lever During the normal operation of the machine power'is a the clutch 23 is brown in by means of the control lever 61 as shown in Fig. 1, causin the shaft 20l to rotate. Rotation of the sha 2O is transmitted to the gears 18, 16 to the main shaft 11, can conveyor 31 and plate 28. The rotatin gear 16 causes the feed drum 62 and can ischarge plate 68 and ejector 69 to rotate, thereby gently feeding the cans 19 in succession into the path of the moving can hooks 47, around the shaft 11 and from the machine.

The milk or other liquid is supplied to the tank 6 through the Ripe 3 upon opening of the slide valve 34, t e float 2 restin upon the liquid in the tank 6. As the leve of the liquid in the tank 6 rises, the float 2 rises and eventually automatically closes the cutolf valve,upon attainment of a predetermined high level of liqluid in the tank 6. As the li uid level in t etank 6 drops, the cut-oilva ve automaticallyl opens and replenishes the suly'in the tank 6 through the interior of the oat 2. The control of milk admitted to the tank 6 is thus effected automatically and an approximately constant head of fluid is maintained in the tank. l n

As the late 28 is rotated, its motion is transmitte through the parallel links 29 and pins 45 to the tank 6 and cylinders 7,

plied to the pulley 21 and causing the tank and cylinders `to revolve about the axis of the bore 43 and to rate relatively tothe plate 28. The revo ving cylinders 7 advance their corresponding rollers 25 along the inclined cam tracks 13, 24 causing the pistons 9 within the cylinders 7 to rise when the cylinders are m communication with the recess 58, and to move downwardly when the cylinders are in com# munication with the cans 19 through the nozzles 56. As communication is established between the tank 6 and c` linders 7, the corresponding pistons are lifted and fluid is drawn by the suction reduced and by virtue of the head of iluid established` in the tank 6, from within the tank 6`into`r the cylinders 7, filling the cylinders andy measuring definite amounts of the fluid;` As communication is established between lll the cylinders 7 and the corresponding dischar e nozzles 56, the fluid is forced from within the cylinders by the descending pistons and is delivered through the nozzles 56 into the cans 19 below, in the form of solid jets. The formation of the nozzles and the -fact that they are interially unobstructed eliminates excessive a itation of the liquidforced therethrough an consequentl eliminates frothing and splashin'hof the liquid deposited into the cans 19. e successive cans 19 are thus automaticallyy filled or sup lied with definite equal quantities of the iquid. n

The quantities of liquid delivered to successive cans may be readily varied by vertical adjust-ment of the cam tracks 13, 24 such adjustment being effected by means of the hand wheels 50. The adjustment may be made without removing any part of the machine and while the machine is in operation. Such adjustment may be desirable in order to increase the clearance in the cans or when filling cans of diil'erent sizes.

The entire machine may be readily dismantled by swinging the inlet pipe 3 out of the way after disconnection thereof, removing ithe u per cross frame 4. The pistons 9 and eir cooperating plates 8, guides 12 and rollers 25, may bev freely vertically removed when positioned at the medial portion of the cam track 13, without disturbing the position of the upper frame 4 or any other part of the'machine. After the upperv frame 4 has been removed, the float 2, cylinders 7 and tank 6 are freely vertically removable. The cam tracks 13, 24 ma be removed by yreleasing the nuts an hand wheels 50. The frame element 57, hearing plate 26, cut-of plate 28 and conveyor 31 may also be vertically removed in succession, by releasin the set screw 32. The screen 30 and li 29 are held in place by gravity and are also readily removed, thus makin all parts of the machine readily accessib e for cleaning, inspection and renewal of parts.

When opleratin on milk, the fat contained in t e m' is forced into the space between coactingI relative] movable surfaces, thus automatically ubricating such surfaces and providing a packingegllxiich prevents leakage and waste of su ces. All movable parts of the machine are rotatable continuously in the same direction thereby eliminating excessive agitation an splashing of the liquid such as would occur in reversing the movement of rapidly movparts. The machine is operable to fill deliver an average of 150 cans 'per minute without wasting .substance or injurmamma f amg a r ro ra ent o wo has belen Ihoiade.J The elimination of I:iomplicated valves and other parte which are andl no4 attention liable to become inoperative further eliminates necessity of attention. As most of the elements may be entirely finished by turning or boring, the cost o construction is reduced to a minimum.

It should be understood that it is not desired to limit the invention to the exact details herein shown and described for variousmodiiications within the scope of the ap nded claims may occur to persons ski led in the art.
