This invention relates to the art ofbottle cappers, and particularly to a unitary device capable of being attached toa bottle filling machine.
.5 An important object of this invention is to provide a simple eflicient mechanism that may be .attached to a bottle filling machine in very close proximity to the discharge point of the machine whereby the bottles filled l0 thereby are capped at once uponleaving the bottle filling machine so as to practically eliminate the exposurev to theair or the cooling of the contents after theV filling operation is completed.
lAnether important object .resides in the provision of a capping device thatmay be operated directly fromV the filling machine in timed sequence therewith and that isadapted, through minonchanges, to be yapplied tothe 0 various makes of. filling machines previously built.
Further objects reside in the extreme simplicity of the Ideviceand in theparticular details.' of the cap attaching members, promot- 225 ing long life and low cost of production.
VAThese and other objects .will become apparent the following description of the invention as shown in one particular form by the accompanying drawings, in which F ig. 1l isa fragmentary side elevation of a bottle filling machine with my invention applied thereto;

Fa-0 The. shaft 26 rextends vdowinjvardly and car'- ries a bevel gear 29 near its lowerendiin mesh With thegear 5,0w which is fixed on the trans.- verse Ishaft 3&1. The outerrend -of the fshaft 3l carries acrank Aarm 32150 lWhichfis reeki825 ably attached they connectingrgd '33 yby the cap Screw 3 4- vThis rod $13 hasa compression spring Yslidingly `slipped thereover v.with its llower .end bearnslaearlst the adjusting .nut .36 screwthreadedly carried .on the rod 133. tubei? telescopieally. lits over'the upperend of the rod 433 with ...a slidingfit Iand .ported verticallyL thereon byresting on fthe washer 38 pressing against .the .upperendfof .95 thelspring 35. The travelof the tube x37 yon thema sa is limited by a. riversa xed in the rod and slidingly passingfthrough" slots Mandel in thetubeb-y its ends. f Thespring normally permits the. rivet', 39. t0 rmaillit fm the lower ends of the slots and 41 as indicated in Fig. 1 and 2.
The upper end of the tube 37 is pivotally secured to the outer arm of the lever 42 which is rockably supported by the frame 20. rl`he other end of the lever 42 is bifurcated to pass around the shaft 23 and engage the collar 43 which is screw-threadedly carried on the vertical head shaft 44. This shaft 44 has its upper end rotatably guided by the horizontal member 45 of the frame 20 and extends vertically therebeyond slidingly through the spur gear 46 and on up into operative connection with the cap hopper 47. The hopper 47 is of the usual construction well known Vto thosev versed in the art and its detailed construction is, therefore, not shown. The shaft 44 has a keyway 48 along one side to receive the keyl 49 as carried bythe gear 46, and a gear 50 on the upper end of the shaft 23 is in constant mesh with the gear 46 so that the shaft 44 may be revolved by the gear 46 as the shaft 44'may slide up and down therethrough.
On the lower end of the shaft 44, is mounted a capping head 51 which has a vertical bore 52 therethrough on an axis removed from the center of the head. This bore 52 is of three dierent diameters, having a small diameter at the upper end serving as a guide for the upper end of the plunger rod 53; an increased central diameter to receive freely therein the compression spring 54; and the largest diameter at the bottom into which is fitted a throat ring 55. The internal diameter of the upper part of the ring 55 is less than that of the bore thereabove so that'the top surface of the ring 55 forms a stop against which'the ring 7 5 on the plunger rod '53 may rest as directed 40 by the compression spring 54 pressing thereon from above. The ring has a vsliding fit in the bore 52. The internal diameter of the throat ring 55 is increased toward the bottom to give the inner wall a nine degree slope from lthe axis. A head 56 freely projects from the end of the rod 53 to within the throat ring 55 4and has its under side normally in the plane of the under side lof the throat ring 55. j A cap ring 57 is fitted into' the lower end of the bore 52 to bear against the under side of the throat ring 55 and is there secured by the retaining nut 58 which is screw-threadedly engaged inthe bore 52. This nut 58 is essentially a ring with its inner walls flaring outwardly. The internal diameter of the cap ring 57 immediately below the throat ring 55 exceeds that of the throat ring and is of suflicient size to receive therein a cap 59. The lower portion of the ring 57 has a diameter slightly less than the diameter of the upper portion in order to form an annular shoulder GOtherearound on which the Vcap 59 may rest. This cap ring 57 is cut through from one side the upper portion soy as to permit a cap 59 to be slide horizontally through that opening and onto the shoulder 60. A key 61 on the side of the ring 57 fits into a corresponding keyway found in the bore 52 to prevent rotation of the ring 57 therein.
The lower end of the head 51 has an annular circumferential groove 62 formed therein and an opening is cut through horizontally from this groove 62 to communicate with the side opening in said cap ring 57. From the hopper 47, extends a cap conductor tube 63 with suitable hinge joints therein. The lower end of this tube 63 is curved around and directed toward the opening through the groove 62 and Vthere maintained by means of the yoke arms 64 and 65 slidingly engaging with in the groove 62; and the pin 66 extending 4from the arm 64 into a vertical guide in the bracket 67 which is fixed to the frame 20. The bracket 67 also carries a guide 68 through which the head 51 may reciprocate vertically.
As the bottles 13 are intercepted in their travel with the table 11 one at a time by the finger 15, a bottle 13 is positioned on the carrier 27 against the rib 28. rl`he carrier 27 is constantly rotated in timed sequence through the train of gears 25, 24, 22, and 21 as driven by the filling machine table gear 12. The capping head 51 is also constantly rotated in timed sequence with the carrier 27 through the gears 46 and 50, shaft 23, and gears 22 and 21 by the lgear 12. The vertical Vaxis of the bore 52 through the head 51 concides with the vertical axis of the bottle 13 when positioned on the carrier 27 against the rib 28, the common axis being at a distance from the common center of rotation of both the head 51 and the carrier 27.y
VSince the' crank arm 32 is continually revolved by means of thehorizontal shaft 31 gear driven directly from the shaft 26, the rod 33 is reciprocated vertically to in turn, through the intermediate` members, lower and raise the head 51. The vertical reciprocation of the head 51 is timed so that as soon as the bottle 13 is brought onto the carrier, Ythe head 51 is lowered to perform the capping operation and then raised to clear the bottle bythe time the bottle has been carried around by the carrier 27 to bring the bottle t into Contact with Vthe stop finger 74, from which position the bottle may be removed by hand or by a conveyor (not shown). On the'up stroke of the head 51, a cap 59 discharges from the lower end of the tube or chute 63 through the lside opening into the cap ring 57 to be ready for the following down stroke. The lower end of the chute 63 is positioned at the proper circumferential locationY to have the opening into the cap ring 57 arrive at the proper time during its horizontal rotation to receive a cap therein while the head'l51 is being raised. yShould a cap 59 be in the ring 57 when the opening is presented to the chute end, a cap from the chute cannot enter by reason of the obstructing cap already there present and the head ma continue revolving as before.
aps are fed down the chute 63 from the hopper 47 on edge and the lower end of the chute 63 is curved around to present the caps '59 to the head 51 right side up in a horizontal plane. Normally the cap at the lower end of the chute 63 bears against the bottom of the groove 62 as it revolves therepast.
Referring now more particularly to the application of the cap 59 to the bottle 13, as the head 51 is lowered with a cap 59 resting in the cap ring 57, the nut 58 passes with considerable clearance over the mouth of the bottle and the cap 59 is brought down to contact the mouth. The cap 59, by continued downward travel of the head 51, is immediately contacted from above by the plunger head 56 which serves to steady the cap and maintain it in a horizontal position over the bottle mouth. As the head 51 continues downward, the spring 54 yields to permit the cap 59 to enter withinand be pushed upwardly into the throat ring 55 thereupon, by reason of the tapered wall of the ring 55, the lateral projecting corrugated lip of the cap 59 is pressed vertically downwards to carry the depressions of the lip corrugations around under the bottle mouth lip at which time the head 51 has completed its down travel and starts upwardly.
Now, as the head 51 is withdrawn from over the bottle 13, the spring 54 returns to its normal position forcing the head 56 down to eject the cap 59, now secured onV the bottle, from the throat ring 55, and, since the annular lip of the cap 59 has been turned downwardly, the cap ring 57 is carried on up over and above the cap 59 without the shoulder 60 striking the cap. The initial height of the head 51 above the bottle 13 is adjustable by means of varying the'position of the collar 43 along the shaft 44 in order that bottles of varying heights may be accommodated thereunder. Also, to provide for slight variations in heights of bottles, and to prevent breakage, the rod 33 yieldingly pushes the tube 37 through the spring 35 which is sufciently strong to position the cap 59 on the bottle normally befor-e the rivet 39 reaches the upper end of the slots 40 and 41 to positively force the tube 37 upwardly.
It is to be seen from the foregoing description of the structure and operation of my invention that I have provided a single rotar bottle capper wherein the bottles are cappe one at a time while in motion from the filling machine. By the close proximity of my capper to the filling machine, which is permitted because of its unique construction, I prevent the heretofore loss of carbonio gas from carbonated beverages, the loss of heat from canned goods such as catsup and the like, or the entrance of bacteria from the air, to a degree not attainable where the bottles or. containers must befcar'ried to anindependent'ly-'operated capp'er remove'dfrom the filling machine.
While Ihave here shown anddescribe'd my invention' in the one form as now bestE known tome, it is obvious that' many struc-v tured changes may be made theref'rom'withL out' departingifrom the spiritf of the invention, and I, therefore, do not desire to be limited'to that form nor any more than-may be required by the following claims.
