BOTTLE-FILLING MACHINE.

Specieation of Letters Patent.

Appueation ined November is, 190s. serial No. 462,449.

To all 'whom t may concern.'

Be it known that I, OREN Cooney, a citizen of the United States, residing at Toronto, Ontario, Canada, have invented certain new and useful Improvements in Bott-le- Filling Machines, of which the following is a specification. Y

My invention relates to a bottle filllng machine and one of its objects is the provision of an improved and efficient apparat-us of this character.`

A further object of the invention is the provision of means for eiiiciently filling bottles arranged -in a plurality of rows.

The novel features of the invention will be described hereinafter where other objects of the invention will appear, and said novel features will be more particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is'an end elevation view of my improved machine with a. tray and guiding devices therefor in section; Fig. 2 is a plan view of the apparatus with the t-ray removed; Fig. 3 is a longitudinal sectional elevation taken on the line 3 3 of Fig. 2 looking inthev direction of the arrows; Figs. 4 and 5 are fragmentary sectional elevations of the pawl and ratchet mechanismV and the locking means taken on the line 4 4 of Fig. 1, looking in t-he direction of the arrows; Fig. 6 is a fragmentary side elevational view showing thc left hand side of the apparatus represented in Fig. 1; and'Figs. 7, 8, 9 and 10 are detail views. 1

1 designates a skeleton frame for support-ing the various parts.

2, 2 designate fixed rails extending longitudinally and receiving the rollers 3, 3', connected to the bottom of the carriage 4 on which vis placed the tray 5, the latter being adapted to-contain a plurality of rows of bottles or other receptacles to be iilled with liquid or other material.

6, 6' designa-te uprights which are connected at their lower ends to the sides of the 'frame work as indicated in Fig. 2. These uprights carry angle irons 7, 8 and 7', 8', spaced apart to form grooves for receiving the guide shoes 9, 9 .which are connected to the respective ends orheads ofthe receptacle or tank 10 which is adapted to contain t-he liquid or other material'with which the bottles are to be filled.

11 designates an opening through which Patented Jan. 30, 1912.

the liquid may be introduced into the tank f 10 by gravity, by pressure or by pumping. If desired, the external port-ion of the material forming the opening 11 may be screwthreaded to receive a cap for closing the tank 10. Such cap may be provided with an eye by which the tank may be lifted into or out of its posit-ion between the uprights 6, 6';

Connected to the lower portion of the tank 10 are a seriesof nozzles 12 corresponding in number to the' number of bottles in each transverse row in the. tray 5. These nozzles are each provided with a valve 13, which valves are connected by links 14 to a universal bar 16 to which is connected at 17 a link 18. To the outer end of this link is pivoted at 19 the lever 20 which in turn is pivoted at 21 to a bracket 22 fixed to the uprightl 6. To the outer end of the lever 20 is pivoted at 23 a push rod or bar 24 which, in this instance, is arranged in vertical position so as to slide up and down in the bearings 26, 26', .which are respectively supported by brackets 25, 25' fastened to the uprightl 6. The lower end of the rod 24 is adapted to be'engaged by the hollowedout portion 27 of the lever 28 which is pivo-.--.d at 29 to the 4plate 30 -mounted 0n the iramework l. It will be seen that the lever 28 is provided with a comparatively long arm 32 to which is connected a handle 31. The other arm of the lever having the recess\27 is comparatively short and it will be noticed in Fig. 6 that the short arm of the lever does not contact with vthe lower end of the rod 24 until the lever 32 is a comparatively short distance from vthe limit of its down stroke. The purpose of this lost motion connection will be explained hereinafter. Fastened to the frame l is a guide plate 33 provided with slots 35, 35 near t-he ends thereof, in which slots are adjustable the respective abutments 34 and 34', so thatl the initial and final positions of the lever 32 and the parts operated thereby may be varied as desired.

To the lower portion of lever 28 as viewed in Fig. 6 is connected a segmental gear 36 which meshes lwith a pinion 37 connected to rotate with a shaft 38. This shaft is mounted in bearings 39 and 40 as indicated in Fig. 1 and extends inwardly as indicated by the dotted lines and to the inner end of the shaft is connected a lever 41 as shown Figs. 3, 4 and 5. To the outer end ofA the lever 41 is pivoted at 42 a pawl 43 to ooperate with the ratchet teeth onthe ratchet bar 44 connected to the under side of the carriagev4. j In this instance this rack bar is connected to substant-ially the central portion of the carriage and extends longi tudlinally thereof, as indicated in Figs. 1 an 3. Y

The pawl 43vis provided with a laterally projecting pin 45 for engaging the flat caml surface 46 which extends laterally from a locking pawl 47. This locking pawl is pivoted at 48 to one of the cross pieces 49 of the framework and is pressed upwardly by l the spring 50, which is fastened tothe cross piece 49 at 51. The outer end of the lockmg pawl 47 is provided with a latch or of the carriage 4 adjacent the ratchetbar 44.

catch 52 to flt in the recesses 53 of a locking rack 54 which is mounted on the under side A latch lever 55 is pivoted at 56 to a j frame or standard 57, which may be fastened to the framework by the vertical plate 58 indicated in Fig. 10.l For this` purpose the longitudinal strip 59 may be incorporated in the framework of the machine.

To the standard 57 is connected a horizontal late 61 provided with a slot 60 for guiding the latch lever 55 and also limiting 'its movement, if desired. Between the plate 61 and alaterally projecting plate'64 connected to the push pawl 43 is a spring 62. The upper end of the latch lever 55 extends through a slot 63 which is indicated in the detail view, Fig. 7. The latch member 55 is provided with a notch 65 a short distance from its upper end and a spring l66, connected at one end at 67 and at the other end to the lever at 68, tends tomove this 4vnotch to the left, as viewed in Fig. 3, so

that when the cam 69 strikes the plate 64 the notch will ride over the outer end of the slot and hold the pawl -43 in depressed position outof engagement with the ratchet teeth 44, thus permitting free return of the carriage 4 to initial position. When the carriage reaches such position the striking device or projection 70- connected to the carriage 4 engages the upper end 71 of the lever 55 to unlock the latching device and .permit movement of the carriage step by step. It will be noticed that the cam 69 is at or near one end of the carriage and that Lmaeae separate compartments `trmed by the partitions 75 in the usual manner and the tray 5'may be-easily' placed on or taken `off the A' 4enga'a'ge therewith or. not, depending upon the height of the rails 2, 2 or the Asize of the rollers 3, 3. Extending under the guide rail 7 8,v 78Y `are retaining members 79, 79 A which, withthe. right angle strips 77 77',

are fastened to the carriage 4 by anyV suit-` able -means, screws 80, being shownl in this instance. It will be seen that the strips 77, 77 form with the retaining members-'7 9, 79,` respectively, guide shoes, ttingover the rails 78, 78 and compelling the carriage to move in a path determined by said rails. The frame work being shown closed at the ends as indicated in Fig. 2, the carriage cannot be removed unless the screws 80, 80 are loosened so that the retaining members 79, 79.may be removed. l may, however, leave the ends ofthe frame work open orl l'provide one endthereof with aremovable i or lnngedclosure so that the carriage maybe withdrawn entirely from the machine while the push pawl and the locking pawl are held out of engagement therewith. The removal of the carriage is desired when a tray of bottlesof larger or smaller diameter are to -be filled, as the length of the ratchet teeth must correspond to the diameter of the bottles in the tray.

To provide for vbottles of different heights I may support the tank 10 at different elevations. This may be done in various ways but l havein this instance shown screws or pins 81, 81 inserted through the angles 7, 8, 7, 8 in' alinement with the shoes 9,9 at the ends of the tank. A series of such openings may be provided so that the tank may be supported at higher or lower levels. As indicated in Fig. 1 if the tank is to be at a higher position than that indicated, the same must be lifted, the screws or pins 81,

81 removed and inserted in the higher open-1 ings 82, 82.

Inorder to reinforce the uprights 6, 6 l have provided a cross piece 86 to the cen- Vter of which at 85 is connectedthe bracing member 84, the inner ends 83, 83 of which contact with the upper ends ofthe angles forming the grooves for the guide shoes at the ends of the tank 10. The outer ends of the cross piece 86 are provided with screw threaded bolts and by means of thumb nuts 87, 87 co-acting therewith the reinforcing 'frame may be fastened in position to the uprights. By loosening the thumb screws the reinforcing frame may be entirely re-V moved and thls is permitted by reason of slotsr88 inthe upper ends 'of theiuprights,

. as indicated in Fig. 6. After the reinforcing'frame is removed the tank 10 may be lifted out of posit-ion after thev spring 89 and the link 18 have been disconnected at 17 from the universal bar 16. A filled tank or one of different size or one having connected thereto a different number of nozzles may be substituted for the one removed and the spring 89 and link 18 again connected to the universal bar. It should be understood that it is desirable to have a different set of nozzles for each particular size ot' bottles if the diameters thereof are different. For instance, if the diametersare comparatively small, a large number of bottles may be placed in the tray and their respective mouths will be spaced apart only short distances and the nozzles musttherefore be spaced 'apart correspondingly and should preferably' be in number the same as the number of bottles of each row.

In some cases it may be desired to vary the throw of the universal bar 16 and I have therefore provided means for adjusting the length of the push rod 24. The lower end of the rod 24 is screw-threaded at 91 as indicated in Fig. 6 and fitting over this screwthreaded end is a cap extension 92, the lower end of which 'is rounded as indicated at 93 to better fitthe recess 27. By turning the extension 92 in one direction or the other, the distance between the lower end 93 and the recess 27 may be varied and set screws 94 may be used to fasten the adjusting member in fixed position relatively7 to the rod 24.

I will now describe the operation of the bottle filling machine. The tank 10 being filled with liquid which is to be introduced into the bottles is placed in proper position at a height depending upon the height of the bottles. The uprights and the reinforcing cross frame combined with the guiding grooves and supporting pins hold the tank and the nozzles connected thereto in fixed position practically free from vibration. The angle irons forming the grooves for the shoes 9, 9', prevent the tank and nozzles from being tilted and the uprights connected by the cross pieces preventv endwise movement of the tank. After the spring 89 which is fixed to the upright 6 at 90 is connected at its other end to the universal bar and the link 18 is also connected thereto, the extension 92 at tlyeflower end of the rod 24 may be adjusted to vary the throw of the universal bar, depending upon the size or kind of bottles used. A carriage provided. wit-h ratchet teeth of a length currespondig to thediameter of the bottles to be filled is placed in the machine and the` guiding and retaining mechanism fastened mplace by means of the screws 80, 80. The tray containing the empty bottles may now be placed upon thecarrage to fit within the corner angle holders 77, A77. Ini-v tially the tray and carriage occupy the position indicated in Fig. 3. Upon movement of the lever 32 away from the stop 34, motionis transmitted through the - gearing 36, 37, and shaft 38 to the lever 41 and push pawl 43, so vas to effect the movement of the carriage and the tray of bottles thereon. When the mouths of the bottles of the first row occupy a position directly beneath the respective nozzles, the latching. project-ion 52 should slip into a` notch 53 to hold the carriage and tray in such position. The initial position of the lever 32 may be varied by shifting the abutment 34 unt-il 80 this operation is obtained. At about the same time or in a short time after this locking of the carriage takes place the recess 27 of the short arm of the lever l28 should engage the lower end of t-he rod 24 so as to v85 transmit motion to the universal lever b'ar 16 against the action of the spring 89. By adjusting the position of the abutment 34. the throw of the lever 32 may be variably limited so that the degree of movement of the valves may be varied. Then the'l universal lever bar 16 is thus actuated, the valves are open and the liquid 'fiows through the same into the bottles and when the latter are filled or partially filled the release of the 95 handle 31 by the operator will permit the spring 89 to automatically close the' valves 13 and cut off the flow of liquid through the nozzles.

Vhen the lever 28 is returned toward ini- 100 tial position the pin 45 on the push pawl 43 will engage with the cam face 73 ofthe plate 46 which extends from the locking pawl 47 and depress the latter out of engagement with the locking rack against the action of the spring 50. 4The locking pawl is held out of such engagement during the remainder of the return of the lever 28 to ini'tial position. The pin 45 will also hold the pawl 47 out of locking position when the 110 operating lever is moved from initial posi-A tion toward final position to move the carriage'one step farther along to bring the next row of bottles under the nozzles and it is not until this is accomplished that the 115 locking projection or latch 52l engages a notch 53. It should be observed that when the locking of the carriage takes place the lever 41 and push pawl 43 are substantiallyv in alinelnent with each other so ,thatvany further rotation of the shaft 38 will not transmit any motion to the carriage but the push pawl 43 will be still held in engagement with the ratchet rack by the spring 62.4 This arrangement is preferred so that at or about the time that the locking takes place and no further movement of the carriage can .be produced, the operating lever may be further actuated to open the valves of the nozzles;

It will therefore be evident that'I have pro- 130 vided apparatus tor movingthe rovvs ot bottles into correct position tor hllng and holding them in such position'vvhile they are bemg' lled. lt will also be apparent that the entire apparatus may be operated at a single point by means ot a single device, or by operating the lever 28 the carriage is -irst moved to correct position, then locked in such position and the valves opened until the bottles are hlled. Upon moving the operating lever in the opposite direction the valves and the parts connected thereto are automatically restored to normal position and the connections between the operating lever and the moving means and locking mechanism are such that the latter also are restored automatically to correct position tor the next operation.

When the last row of bottles have been filled and the operating lever is moved back t to initial position, the Hat plate 64 on the push pavvl will engage the cam 69 and cause the pawl to be depressed until the notch 65V holds it against upward movement. 'lhis will be clear by reference to Figs. 3 and 7. The notch"v 65 is in such position that the pawl is held entirely out of engagementvvith the rack bar so that the carriage may be returned to initial position. When this occurs the 'striking device 70 engages the upper end 71 of the latch lever 55 and restores the push pawl-to normal position ready for the next operation of filling another tray ot bottles.

. Obviously those skilled in the art may make various changes in the details and arrangement of parts without departing from the spirit and scope ofmy invention as defined by the claims and I Wish therefore not to be restricted to the precise yconstruction herein disclosed.

Having thus any described, my inventan what I claim and desire to have protected by LettersPatent of the United States is-.
