BOTTLE FILLING AND cnPPINe MACHINE.

Specification of Letters Patent.

Patented June 8, 1909.

Application filed February 20, 1907. Serial 'No. 358E475.

1T0 alt/whom it mayconcert:

lBe it known T that I, Gnome KIRKEGAA RD, a citizen oi the United States, and a resident of the city'ofNew York, in the county of New York'and State of New York, United Etates of America, have invented certain nc-W and useful Improvements. in Bottle iFilling andGapping Machines, of which the following-isaspecification.

My invention relates to abottle filling and capping machine and its object is to-provide an efficient apparatus for securing bottle stoppers or-caps over the mouths of bottles or ars which have been filled under pressure.

[will describe my invention in the follow- 1ng specification and point out the novel features" thereof in claims.

lleferring to the drawings, Figure lshows insideelevation, partly in section, my improved; bottle capping machine. 2 shows in side elevation, partlyin section, a modified form of on'epart of'the mechanism shown'in l ig. 1. Fig. 3 is-a sectional plan 'view of aclosing device which may *be apthe section erng'takenthrough the'line 33 of Fig. 4. -Fig. 4 is a sectional side elevationshowing :this closing device. Fig. 5 is a side elevation of a bottle capping head which I have invented and which I use in carrying out this intention. Fig. 6 is a sectional side eleva tidn of the structure shown in Fig. 5. Fig. 7 is'a'plan view of the bottle capping head which-isshown in Figs. 5 and 6. This bottle capping head has been made the subject of a separate application [or patent filed by me under date of October 1, 1906, therialv Number, 336,831. Big. 8 is a perspective view of a bottle, cap which I ha'veinventedand which they be used in conjunction with the present invention for capping bottles.

designates a baseor'framework upon which the various parts 'oi' m apparatus are mounted. -1'1--are vertica standardsco'm nected with this framework and'arranged to rnounted'u 3011 these'standards and arranged to'iae hel' thereon at desired heights by nreansofhandscrews 13. At a'point 14 on this supporting-carriage is pivoted hand lever 15. 16 designates a slot in this hand lever. A'pin 17 is arranged to pass through.- the slot 16.

20 designates a spindle'sndably'mounted in the supporting-carriage 12. A connect ing shaft 21 is secured into the upper endwf this spindle and locked thereto by meansof a nut 22. A collar 23 may be'interposed between this nut-and the top of-the spindle. The s indle and the connecting shaft-are suitably guided by the supportingcarriage' at 18 and 19. A compression spring24-be tween the part 19 of the supportingmarriagr'e 12 and the. collar 23 serves the urpose of normally maintaining the spindle and its associated parts in their upper position. The nut 22-striking upon the portion 18 of the supporting-carriage limits the upward movement of these parts. The spindle is hollow and is arranged to carry a compres sion shaft 25 whichis ressed outward from -the spindle by means 01 a compression spring 26. This corn )ressiorrshal't 25 is constructed to'form a shoulder 27 and a plunger 28 which extends below it and which is somewhat I smaller in diameter than the shoulder 27.

3Q designates a forming-head which is 0011-" structed of three

sectors

31, 32 and 33, which? are substantially alike in construction and 85 which are held together by-mcans of. springs 34 and 35l The inner surface of each olt these sectors isprovided with acam groove 36. The construction and operation oft his forming-head are specifically described in my. former application for patent Serial 'Num-f. ber 336,831. 1

56 is an outlet passage from the cylin drical filling chamber which is connected with the discharges ipe 58 through a safety valve 57 of any wel iDOWIl construction.

A spring 29 ma be interposed between the portion 19 of tl ie-sup ortmg-carriage 12 and upper part of the filling chamber casing e lower end of this cylindrical filling chambercasing 50 is constructed to form a somewhat sharp edge as is shown at 59.

60,60 designate a pair of-slides which are horizontally guided in properly constructed slots in the supporting-frame 10. These slides 60 are connected by means'of bellcrank levers 61, 61, which are pivoted at 62, 62 in the sup orting-frame 10, with vertical rods 63, 63 w rich are in turn connected with a treadle 64. These

vertical rods

63, 63

are arranged to be pressed u ward by means of

springs

65, 65 to move t e slides 60, 60 outward.

66,, 66 "designate two packing=blooks of rubber or other suitable material which are mounted upon the

slides

60, 60, and each of these packing-blocks is provided with a semi-circular opening which, together, are .adapted to fit tightly around the neck of a bottle 67. In the modification of my a ratus which I have shown in Fig. 2 t ere is but one of these slides 60 shown with its rod 63 through the bell-crank lever 61.

, ranged to be 72 and a plurality of depending fingers In operatingthis device a bottle 67 is laced upon a portion 68 of the supportingrame 10 which is provided for thispur ose.

The 0 erator then de resses the tread e 64 and t ereby forces t e packing-blocks or

collars

66, 66 in against the neck of the bottle 67. The slip citing-carriage 12 ,is then moved downwar until the lower edge 59 of the cylindrical filling chamber 51 is brought into close contact with the packing-collar 66 and is forced into the latter slightly by means of the spring 29. The sharp edge of the casing'50 will cause the latter to be depressed somewhat into the resilient surface of the ,ackin'g-collars, and the under or tions oi the slides 60 are .constructe as shown to come directly underneath this edge in order to firmly support the packing. lVhen the parts have been thus moved into the desired position they may be held therein The valve 54 may then be turned to open a passage from the supply pipe 53 to the cylindrical filling chamber and the desired fluid will thereby be forced into the bottle 67. The parts above described will term means for retaining pressure about the mouth of the bottle so that the pressure from the su ply pipe 53 will be maintained in the bottle itself. A cap 70 has been placed upon the 7 lower end of the compression shal t 25 and retained in position by the forming-head 30. If desired the compression shaft 25 may be magnetized to assist in retaining the cap in its proper position as the cap itself is generally constructed of magneticm aterial. Now, whenthe lever 15 is moved downward the compression shaft 'with its cap is moved down until the latter is arrested by coming in contact with the mouth of the bottle. A further movement of the lever 15 will cause this cap to be pressed tightly down upon the bottle under the action of spring 26 and the packing material within the cap will thus become forcibly compressed. The forminghead 30 is then moved down past the mouth of the bottle and the cam grooves 36 in the forming-head will cause the fingers or lugs 73, 73 to be pressed in under the rim or head 69 about the mouth of the bottle. The forming-head is constructed as shown of separate'sectors to prevent undue pressure upon the parts from breaking the bottle. During the downward movement of the cap applying head, the space in the filling cham- "ber around the bottle neck becomes more and more restricted, owing to the downward movement of the piston 43 in its cylindrical bore. The fluid in this chamber-is accordingly expelled outward through passage 56 and pipe 58, and when the piston has fully descended to the point where the cap applying operation takes place, almost al the entire body of this fluid is expelled. At this time the bottle neck projects upward into thecavity of the piston 43 and the latter rests upon the flat upper surface of the packing blocks 65. Owing to the special shape of the piston, the amount of fluid which is retained in the bore and spilled during the removal of the bottle, is comparatively slight.

by means of the hand screws 13, 13.

It may be seen that the pressure about the mouth of the bottle is maintained at all times during this operation. Ifdesired an auxiliary valve 42 may be inserted in the passa e 42 in order to increase this ressure slightly during the. operation. If t 10 pres' sure becomes too high for any cause the safety valve 57 will release it. The lever 15' will now be released and the spring 24 will eause the latter and its connected parts to be reeaasco turned to their former position. The supporting-carriage 12 may now be raised tore- ,move the filling chamber from the bottle and the treadle may be released to cause the packing-collars to be moved away from the neck of the bottle.

It is to be understood that the rim or shoulder 43 of the piston 40 Which supports the forming-head upon the spindle 20 may be constructed tohold these parts loosely in order to leave the various sectors o i the form.- ing-head free to move outward against the action of the springs 34 and I have described my invention applied .to a bottle cap of specific construction in order to illustrate my improved apparatus. It may, however, be applied to other l'orms oi bottle caps with very slight modification of the parts.
