Specification of Letters Patent;

Patented Oct. 16, 1906.

Application filed August 13. 1904:- Serial No. 220,655-

To all whmn it may concern: 7

Be it known that I, WILLIAM HENRY SHEE- FIELD, a citizen of the United States, and a resident of Hobart, in the county of Delaware and State of New York, have invented a new and Improved Filling Apparatus, of

which the following is a full, clear, and exact and other liquids into a number of bottles or receptacles moved intermittently over a stationary table, the arrangement being such that the waste or loss of the liquid is reduced to a minimum and the receptacles are 3 0011% rately and uniformly filled to the desired height. v t

The invention consists'of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of .the invention is represented in the accompanying draw ings, forming a part of this specification, in

which similar characters of reference indicate corresponding parts in all the views.

'Figure 1 is a side elevation of the improvement. on the line 2 2 of Fig. 1. Fig. 3 is a crosssection of the device for imparting an intermittent traveling motion to the receptacle' pushing device. Fig. 4. is a rear end elevation of the improvement. Fig. 5 is an enlarged crosssection of the improvement on the line 5 5 of Fig. 7. Fig. 6 is a sectional side elevation of the closing-head for the end of one of the supply-tubes, the section being on the line 6 6 of-Fig. 5; and Fig. 7 is an enlarged longitudinal sectional elevation of the improvement on the line 7 7 of Fig. 4.

The bottles or receptacles A to be filled are set in transverse rows on the rear end of a table B, fixed on a suitable frame 0, the rear I end of the said table terminating in a downwardly-extending apron B to facilitate passing the bottles over the apron onto the rear end of the table. forward over the table in the direction of the arrow (1 by the use of a pushing device I Fig. 2 is a cross-section of the same chain E.

The bottles A are pushed j consisting, essentially, of endless sprocketchains D D, passing over sprocket-wheels .D D', journaled on the rear and front ends of the frame C, and the said endless sprocketchains are connected with each other by cross-bars D, spaced apart to embrace two transverse rows of receptacles between adjacent bars D, as plainly indicated in Fig. 1.

The table B is provided with rising sides B formed with outwardly-extending integral flanges B (see Figs. 1 and 2,) on which rest and travel the upper runs of the sprocketchains D D and the outer portions of the cross-bars D employed for pushing the bottles over the table. By the arrangement described the sides B of the table prevent the bottles from scattering transversely, and the bars D prevent the bottles from scattering lengthwise, so that the bottles are at all times in proper alinement to permit their convenient filling and-to facilitate the pushing of the bottles over the table B. As indicated in the drawings, two rows of bottles are filled simultaneously, it being understood that the rear row of bottles is pushed by a bar D and the front row of bottles is pushed upon by the rear row, as will be readily understood by ref erence to Fig. 1.

In order to give the desired intermittent motion to the pushing device, a shaft D ,car rying the front sprocket-wheels D is provided with a sprocket-wheel E, over which passes a sprocket-chain E, also passing over a sprocket-wheel E having its shaft E journaled in suitable bearings on the frame C. A ratchet-wheel E is secured on the shaft E and is engaged by a spring-pressed pawl E fulcrumed on a hand-lever E, loosely fulcrumed on the shaft E so that when the operator swings the hand-lever E upward the pawl E glides over the teeth of the ratchetwheel E, and when the operatorswings the hand lever E downward then the pawl E turns the ratchet-wheel E andwith it the shaft E so that the rotary motion of the latter is transmitted to the shaft D by the sprocket wheels E E and the sprocket- The rotary motion of the shaft D causes a traveling of the sprocket-chains D D and their cross-bars D to push the bottles over the table B in the direction of the arrow 0/, as previously explained.

I The liquid-supply F is preferably in the form of two transversely-extending tubes F and F rigidly connected with each other at or near their middle by a saddle F connected by a coupling F with a flexible tube G,

leading from an overhead tank or other suitable liquid-supply, so that the liquid flows by its own gravity through the tube G and the hollow saddle F into the tubes F and F to keep the same constantly filled with the liquid. The ends of the tubes F and F are at tached to cross-heads F mounted to slide up and down on vertically-disposed guide-rods C, forming part of the main frame 0.

On the under side of each of the liquid-supply tubes F and F is secured a transverse row of filling-tubes H, adapted to pass into the corresponding row of bottles A, the lower ends of the said filling-tubes h reaching within a short distance of the bottoms of the bottles A at the time the liquid-supply F is in a lowermost position. (See Fig. 7.) Now the liquid flowing from a tube F or F by way of a filling-tube H into the corresponding receptacle A does not foam or froth, and consequently proper filling of the receptacle is the result. The 'upper ends of the filling-tubes H are screwed into the tubes F or F said tubes H having suitable wings H for convenient turning of the tubes by the operator to allow of removing a filling-tube whenever it is desired to do so.

The upper terminals of the filling-tubes H within the supply-tubes F and F are norrnally closed by valves I, having valve-stems I extending down through the filling-tubes H to engage the bottoms of the receptacles A at the time the liquid-supply F moves into a lowermost position, so that the valves I are lifted off their seats to open the filling-tubes H to the liquid to allow the latter to flow through the filling-tubes H into the receptacles A to fill the same.

- On each of the filling-tubes H isarranged a tubular air-vent J, mounted to-slide vertically in a bearing K, formed on a drip-pan K, having cross-heads K mounted to slide up and down on the guide-rods O, previously mentioned. On the lower end of each air-vent J screws a seat L, engaged on top by a metallic washer L, against which screws a nut L screwing on the lower threaded end of the tubular air-vent J, and on the said nut L -presses one end of a spring N, coiled on the air-vent J and abutting with its free end on the bearing K. (See Fig. 7.) The seat L is preferably made of rubber and is adapted to be seated on the top of the corresponding receptacle A, so as to close the mouth thereof and direct the air escaping from the receptacle A during the filling operation into the air-vent J and through the same, the air-vent also serving as an overflow in case the supply F is not raised by the operator after the receptacles are filled to the desired height. Now such liquid rising in the air-vent J flows over the upper end thereof and down an inclined flange J into the drip-pan K to accumulate therein.

By screwing the nut L up or down on the air-vent tube J and moving the washer L and the seat L correspondingly with the nut L I amenabled to regulate the distance the lower end of the air-vent tube J is to extend into the receptacle A to fill the latter up to the lower edge of the said vent-tube J. The extent to which the vent-tube J is entered into the receptacle determines the amountof liquid to be filled into the receptacle.

In order to permit the free flow of the liquid down each filling-tube H, the latter is provided above the drip-pan K with a ventaperture H surrounded by a hood or deflector H secured to or forming part of the filling-tube H and serving to deflect any liquid that passes out of the said aperture H down into the drippan K and also any-liquid that passes out of the vent J, and thus prevent spurting of the liquid.

The drip-pan K and the liquid-supply F are moved simultaneously up and down on the guide-rods C, but at a different rate of speed, and for this purpose the following device is provided: -A transverse shaft O is journaled in suitable bearings carried by arms O attached to the guide-rods C between the cross-heads F and K as plainly shown in Fig. 1 of the drawings. On one outer end of the shaft O is secured a handle O (see Fig. 4) under the control of the operator for impart ing a rocking motion to the said shaft O on moving the handle up and down. On the shaft O are secured arms P, connected by pitmen P with pins P secured on brackets F, forming part of the cross-heads F so that when the shaft 0 is turned in one direction by swinging the handle O downward in the direction of the arrow 1) then the arms P and pitmen P impart an upward sliding motion to the liquid-supply F, and when the handle O is swung in the reverse direction of the arrow I) then the liquid-supply F is moved downwardly on the guide-rods C. On the shaft 0 are also secured cams Q, having camgrooves Q, in which are mounted to travel friction-rollers Q (see Figs. 5 and 7,) journaled on brackets Q secured to the crossheads K of the'drip-pan, so that when the shaft O is turned on swinging the hand-lever O downward then the drip-pan K is raised by the action of the said cams Q and the friction-rollers Q journaled in the brackets Q attached to the drip-pan, and when the handle O is swung in the reverse direction of the arrow 1) the drip-pan K is lowered; but by reference to Fig. 7 it will be seen that the upward sliding motion of the drip-pan K is considerably slower than the upward movement of the liquid-supply F, and consequently the seat L remains seated on a bottle A until after the valve I for the corresponding fillingtube H has moved into a closed position, and

thereby shut off. the filling-tube H from the liquid contained in the corresponding tube F or F In a like manner when the drip-pan K and the liquid-supply F move downward the seat L moves in engagement with the bottle A previous to the stem I striking the bottom'of the bottle, so that the bottle A is closed on top at the time the valve I is lifted off its seat and the liquid begins to flow from the corresponding tube F or F into the bottle.

The drip-pan K is provided on its bottom with discharge-spouts K preferably two in number, for delivering the liquid accumulated in the drip-pan K-into two of the bottles A held' in the row immediately in the rear of the rear row of bottles to be filled at the time, as will be readily understood by reference to Figs. 4 and 7, it being understood that the said discharge-spouts K are in vertical alinement with the mouths of the corresponding bottles A. The spouts K are adapted to be closed by valves R, having their stems R attached to a lever R fulcrumed on a bar R fastened to the drip-pan K and moving with the same, and the lever R is adapted to be engaged at its free end by the hollow saddle F so that when the liquidsupply F moves into a lowermost position the said saddle F imparts a swinging-motion to the lever R to lift the valves R off their seats and allow the liquid contained in the drip-pan K at the time to flow down the spouts K into the two corresponding bottles A below. In order to bring these two hottles which receive the liquid from the drippan K into proper alinement with the spouts K and to center the receptacles to the fillingtubes H, I prefer to employ two guide-arms S, one of which is shown in Fig. 7, secured to the drip-pan K and moving with the same and adapted to engage the bottles at their outer sides, so as to push the same close together, and consequently into alinement with the spouts K The lower ends of the guidearms S are preferably provided with longitudinal arms S, as plainly indicated in Fig. 7, to gradually push the two bottles close together previous to the bottles reaching their nal position for receiving the drip liquid.

When the liquid-supply F and the drip-pan K rise, but with the liquid-supply traveling faster than the drip-pan K, then the lever R is released by the saddle F and the valves R by their own weight now close the discharge-spouts K In order to allow periodical cleaning of the tubes F and F each of the latter is provided at each end with a removable cover F, fastened in place by a screw-rod F screwing in a yoke F removably held on the corresponding end of the tube F or F (See Figs. 5 and 6.)

Any liquid that drips onto the table B is pushed forward thereon by the forwardlymoving bottles A and is finally discharged from the table by a discharge-pipe 13*, leading from the bottom of the table to one side of the apparatus, as plainly indicated in Figs. 1 and 2.

The operation is as follows: When the han- 7o rows of bottles to be filled in alinement with two rows of filling-tubes H, depending from the tubes F and F of the liquid-supply F. When the bottles have reached the desired position, then the operator moves the handle O upward to move the liquid-supply F and the drip-pan K simultaneously downward for the seats L to engage the upper ends of the bottles A and for the filling-tubes H and the stems I to pass into the bottles. The valves I are finally opened, as previously explained, so that the liquid can flow from the supply-tubes F and F into the bottles A to fill the same. As soon as the receptacles are filled to the desired height the operator in charge of the machine swings the handle 0 downward, so as to cause an upward movement of the liquid-supply F and the drip-pan K, as previously explained, to cause the valves I to automatically seat themselves, and thereby prevent further outflow of the liquid from the supply-tubes F and F It is understood that when the liquid-supply F moves into its lowermost position, the valves Rare lifted off their seats on the dischargespouts K to allow any liquid that may pass tion to readily flow through the said discharge-spouts into the two receptacles in the foPowing first row of empty receptacles to be fil ed.

Although I have shown the mechanism for imparting an intermittent motion to the pushing device and the mechanism for imparting an up-and-down movement to the liquid-supply F and the drip-pan K as being operated manually, it is evident that the said devices may be actuated automatically in proper succession by power.

Having thus described my invention, I
