SPECIFICATION forming part of Letters Patent N o. 768,960, dated August 30, 1904.

Application filed July 9,1903. Serial No. 164,815. (No model.)

To @ZZ whom, it 712/07/ con/067%.'

Be it known that I, FRANK C. H. STRASBUR- GER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bottle-Filling Machines, of which the following` is a specification.

This invention relates to novel improvements on the bottle-filling machine covered by ro United States Letters Patent N o. 7 32,065, dated June 30, 1903; and its objects are primai-ily to compel proper positioning of each bottle in the machine and provide for automatically discharging the bottles after they have been illed.

In the accompanying drawings, Figure lis a central sectional View of a machine embodying the invention, two filling tubes and valves only being' shown to avoid confusion. Fig. zo 2 is a similar view on the line 2 2 of Fig. 1.

Fig. 3 is a detail view of the connection between the actuating-lever and a bottle-rest. Fig. 4; is a top plan View of the bottle-chute, showing two bottle-rests in relative position thereto. Fig. 5 is a side elevation of the bottle-chute, showing' the forward bottle-rest a little in advance of its position in Fig. I and slightly elevated. Figs. 6 and 7 are detail views of the actuating-cam and its guard. Figs. 8 and 9 are sectional views of one of the filling-valves. I

Like numerals of reference indicate corresponding parts in the several gures of the drawings, and referring thereto 12 is a base 3 5 of suitable character, and 13 is a drivingshaft journaled in bearings 14 and carrying the belt-pulleys 15 and a worm 16, meshing with the worm-gear 17 on the vertical driven shaft 18. A plate 19 is fastened on the driven shaft above the base and carries at its periphery a number of arms 20, each of which is bored to receive and guide the stem 21 of a bottle-rest 22. The bottle-rest isprovided with a guard 23, Figs. et, 5, andan extension 24 for apurpose hereinafter described. The bottle-rest is thrust upward by means of a crank-lever which is preferably in the form of an elbow and has its long arm 25 con-- nected bylinks 26, Fig. 3, with the upper part of the stem and its short arm 27 provided 5o with an antifriction-roller 28, arranged to travel around a cam 29, rigid with the base. The actuating-lever is carried by a support 30, which may be connected with the plate 19,

as shown, or made independent thereof.

The machine may be constructed to 'accommodate at one time any number of bottles; but in Figs. 1 and 2 I have shown but two sets of the illing mechanism to avoid Confusion.

It will be understood, of course, that the cam is constructedto move the bottle-rest up- `Ward after the empty bottle has been placed thereon and hold it .up in engagement with and to open the iilling-valve until the bottle has been filled, at which time the cam permits the bottle-rest to descend, so that the illed bottle can be removed. For the purpose of insuring the descent of the bottle-rest with the filled bottle at the proper time I provide a guard 29, Figs. 6, 7, at this part of 70- thecam, which provides a groove or channel in which the roller on the actuating -lever travels. The guard `compels the roller to follow the cam, and thus insures the descent of the bottle-rest at the proper time. The tank 35 is mounted on the upper end of the driven shaft and is provided with a removable cover 36, adapted to be fastened securely in place to conne the pressure therein. A regulating-valve 37 is provided to control the pres- 8O sure in the tank. A feed-pipe 38 is arranged in a stuffing-box 39 in the cover of the tank and discharges at its side into a spout 40, which is carried by oat 41, provided with a sleeve 42 to receive the pipe 38. 8 5

The lower end of the pipe 38 is closed, and it discharges at the side into the spout 40 when alined therewith, so that the beer will pref,- erably be discharged close to the bottom of the tank to avoid producing foam. When the 90 oat is in its lowest position, the spout will be alined with the discharge-opening in the side of the feed-pipe; but as the beer rises in the tank it will carry the float up with it until the spout is out of alinement with said dischargeopening, and thus cut off the supply. The

float thus automatically regulates the supply of beer in the tank, and it can be suitably constructed and set to vary the quantity as desired.

I do not claim herein the valve mechanism, as this forms the subject-matter of a divisional application, Serial No. 197,794, filed March 1Q, 1904. Bricfly,ythe valve mechanism comprises a body 43 with a central bore 45, communicating with the filling-tube 46, which extends through the enlarged bore 55 of the head 50. The liquid-valve 48 is connected to the head by rods 49, and springs 51 on the rods hold the valve normally seated. Then a bottle is forced against the seat 58 on the head, the latter is raised and the valve 48 is unseated to permit the liquid to fiow into the bottle. To equalize the pressure in the bottle and tank, I provide a passage 59 in the body 43, which opens at its lower end in a space inclosed by the gasket 56 between the body and the head and at its upper end in a chamber GO, which contains the spring-pressed valve 61 and communicates with the tube 65. The stem 62 is arranged to be engaged by the head on its initial upward movement to unseat the air-valve, and thus permit equalization of pressure in the bottle and tank before the liquid-valve has been completely opened.

A discharge-chute 69 is supported on a bracket 70 and provided with an arm 71, which projects across and above the path of movement of the bottle-rests when they are in position to discharge the filled bottles, Figs. 1, 4, 5. rI`he inner end of the bottom 7 2 of the chute projects beneath the bottle-rests and is recessed on its upper face at 73 to receive the bottle-rests, so that the bottle may slide from the rest in the same plane onto the bottom 72 of the chute. The bottle-rest carries the bottle against the arm 71, which causes the bottle to slide toward and onto the extension 24 of the rest, whereupon it is engaged by the next bottle-rest and pushed into the chute. In this way the bottles are automatically discharged from the machine and push each other into the chute without requiring any attention on the part of the operator, so that the machine can be run at a comparatively high speed. The chute may be constructed of a size adapted to receive a large number of bottles, or it may communicate with a convcyer for carrying the bottles to the sterilizer or to the labeling-machine. r[he bottle-rest reaches its lowest position when about to discharge the bottle and carries the mouth of the bottle below the filling-tube, so that the bottle can be discharged without tipping; but I prefer that the operator shall properly arrange the empty bottle on thc rest, with the lower end of the filling-tube in the mouth of the bottle to avoid all liability of the fillingtube striking' the wall of the bottle-mouth and breaking it. I therefore construct the cam so that it will raise the bottle-rest slightly after it discharges the bottle, as shown in Fig. 5, and I provide a guard 74 on the arm 71 of the chute. The guard prevents the bottle being arranged on the rest until it has moved upward a little from its lowest discharge position, and when in this position the bottle can only be arranged thereon by tiltingI it in the manner shown in Fig. 1 to cause the filling-tube to enter its mouth. This prevents the operator from carelessly arranging the bottle in the machine, which might result not only in the breaking of the bottles, but also in injuring the filling mechanism and wasting the liquid.

It will of course be understood that for each bottle in the machine there is an independent mechanism for raising the bottle and an independent valve mechanism, and therefore a machine can be constructed to accommodate at one time as many bottles as may be desired. The cam is preferably timed so that the bottle will descend immediately or shortly after it is filled and so that it can be discharged properly into the chute. The construction may be such that the operator can insert two bottles at a time, and as the bottle itself is utilized to open the valve it will be apparent that should the operator fail to arrange the bottle on a rest the valve mechanism would not he operated, and hence none of the liquid would be wasted, and as the bottle is tightly clamped against the head it does not matter particularly how long the valve remains open.

The invention can be embodied in machines which differ more or less in construction from the one illustrated in the drawings and herewith described, and I would therefore have it understood that I reserve the right to make all changes which may be fairly considered to come within the purview of my invention.

I have described the machine as used for filling bottles with beer; but this is only one of the uses of the invention, and it can be used in same manner for filling' bottles with other liquids.

Without limiting myself to the exact construction and arrangement of parts herein shown and described, what I claim, and. desire to secure by Letters Patent, isf*- 1. In a bottle-filling machine, a number of bottle-rests adapted to support the bottles to be filled and each provided with an extension on one side thereof and a guard on the other side, a chute to receive the filled bottles, and an arm projecting across the path of the bottles to sweep each bottle onto the extension of its rest and into position to be pushed into the chute by the guard on the followingI bottle-rest.

2. In a bottle-filling machine, a number of bottle-rests provided with extensions, a chute to receive the filled bottles, the bottom of said chute being projected beneath the path of movement of the bottle-restsl and recessed on IOO its upper face to receive the` bottle-rests so that the bottle may slide therefrom Vinto the chute in the same plane, and means for discharging the bottles from the rests.

3. In a bottle-filling machine, a number of rests for holding the bottles and arranged to travel in a substantially circular orbit from receiving to discharging positions, each of said rests being provided with an extension extending rearwardly according to its direction of travel and adjacent to the it'ollowing rest, means for moving the bottle from its tilling position on the rest onto the extension thereof, and means on the following rest for pushing the bottle oli' of the extension ot' the preceding rest. f

4. In a bottle-filling machine, a number of iilling-tubes, a bottle-restlocated beneath each iilling-tube and traveling' therewith, and means for moving' the bottle-rests vertically, said means operating to carry the lilled bottle down so that it can be removed from thel machine without tilting and thereafter moving the bottle-restup slightly to compel the tilting of an empty bottle to be inserted on the rest with the end of the lling-tube in the mouth of the bottle.

5. In a bottle-lling machine, a number of filling-tubes, a bottle-rest located beneath each lilling-tube and traveling therewith, means for moving the bottle-rests vertically', said means operating' to carry the filled bottle down so that it can be removed from the machine without tilting' and thereafter movingv the bottle-rest up slightly to compel the tilting ot' an empty bottle to be inserted on the rest with the-end of the tube in the mouth thereof, and a guard arranged to prevent the insertion of a bottle on a rest while in its discharge position.
