Application filed October 30, 1909. Serial No. 525,582.

To all whom it may concern:

Be it knownthat I, THOMAS J. LEVEY,

a citizen of the United States, residing at lVashing-ton, in the District of Columbia,

make and use the same.

This invention relates to bottle capping machines, and has for its object to produce a machine of this nature which will be'more compact, cheaper to construct, and more efficient in .LCtlOD than those now in use.

1th these'objects in view, the invention consists-in the novel. details of construction and combinations of iarts more fully hereinafter disclosedan particularly pointed out in the claims. Referring to the accompanyingdrawings forming a. part of this specification, in, which like numerals refer to like partisan;

shaft and pulley; as will be readily understood. 5 represents a springfor normally forcing the said key 4 into the hub of the pulley 1, and 6 is a beveled vertically moving rodadapted to take against the inclined end of the key 4 and to move the said key out of engagement with the hub of said pulley 1.

7 is a spring for normally holdin the rod I 6 in engagement with the ke 4, an 8 represents a crank which may e of the-form shown and which is pivoted at 9 and is provided with the foot lever 10, as will be readily, understood. The end-.11 of the crank 8 engages the rod 6, and when the foot lever 10 1S depressed said end 11 will cause said rod 6 to. be likewise depressed and to thereupon permit the spring 5 to move the key 4 into engagement with the hub of the pulley 1 and therebyconnect said pulley with the shaft 2. When the 'foot lever 10 is released a suitable spring 12 restores the parts to their normal position,

as will .be clear from the drawings. The 4 power shaft is further provided with a lug l3 keyed at 14 to the said shaft, and said lug is provided with two jaws 15. between which is pivoted, as at 16, the dog 17 controlled by the spring 18 whichzmay be adjusted by the screw bolt 19, as will be readily understood. The lug 13 is provided with the smaller bifurcated lug 20 between the parts of which is pivoted, as at 21, the trigger 22 againstthe toe 23 ofwhich the' pawl 17 takes. The-trigger 22 is controlled by \the sprin 24, the tension of which may be adjusted by the screw bolt 25. This screw bolt may be "adjusted to and from the pivot 21 by moving the same in the slot, 26, with which the arm. of the trigger 22 is provided, and'by this adjustment the amou'n't'of leverage or power required: to trip the trigger 17 is readily controlled.

Loose on the shaft 2 is a hub 30, provided with a gear 31 meshing; with the vertically moving rack 32 guide by alug 34 on the machine, which lug is preferably madeLin two parts, as indicated, and is provided w th anti-friction rollers 35., This hub- 30 is also 1, provided withan'extended arm 36, the upfper end 37 of which is bent at rightangles, as shown in Fig. 7,-to form a-lug, 38,. having against which a lug 17 on the dog 17 is adapted to abut. The vertically moving rack 32'is connected as at 41 to a rod 42 which extends through the upper part of the machine and has connected at itsother end the cross is secured the capping head 43' in which mechanism.

represents a spring surrounding the rod 42 the tension'of which may be adjusted by .the collar held on the rod 42. This spring normally holds the capping mechanism in a raised position, as shown in Fig. 1; and to provlde for the assembling and ad justment of the parts a door 46 hinged at 47,

is provided in the upper part of the machine. Securely held in theouter end of the cross head 43 is the plunger stem 44 of the bottle I capping mechanism. This stem is screw threaded as at 45 to accommodate the sleeve 46 and has a reduced lower end 47 as shown.

Surrounding this reduced end is the slotted cam sleeve 48, and surrounding said sleeve 48 is the slitted tubular capping member 49.

. Pins 50 passthrough the arts '47, 48 and 49 to hold the same secure y together. The sleeve 48 is provided withthe cammembers 51 and the capping member 49'is provided with the crimping projections 52. The stem 44" is preferably enlarged at 54, and provided with the slot 55 which receives the weighted lever 56 pivoted at 57 to a stem.58

'below.

passing through the lower end of the plum ger stem and screw threaded .at 60 ,tothe tubular stem 61 of the cam head 62. The

stem61 is slotted at 63 to receive the pin 64, passing through the stem 65 of the auxiliary head 66. The head 62 is provided with an opening to receive the-stem 65', as illustrated.

Surrounding the tubular stem 61 and resting on the pin 64 is the sliding .collar 67, and also surrounding said stem ,61 and resting above the collar is the spring 68, while above said stem 61 and surrounding the lower end of the rod or stem .58is the spring 70, all as will be clearly understood from the draw- The auxiliary head66 may be; provided with't-he' projection 7 5, as shown in Figs. 3 and 4, or this projectimi illustrated 'in Fig. 6.

maybe omitted, as

The operation of this machine is as follows :-Power being applied to the loose pulley 1, the same runscontinuously, and

when the operator depresses the lever 10, the

end 11 of the same draws down the rod 6,"-

permitting the dog 4 to be moved by the spring 5 into engagement with the hub of the pulley 1, thereby locking the same to-the shaft 2, a iid causing the same to rotate. The shaft 2 rotates the lug 13 and d0g l7, which in turn by reason of the engagement of the shoulder 17 with the lug 38 causes the arm.

36 and hub 30 to revolve and the gear 31 to I pull down the rack bar 32 and rod 42 against the tension of the spring 44. The downward movement of the rod 42 causes the cross head 43 to move downward being guided in thismotion by the extension 78, taking inthe ways 79 rigid with the machine. The plunger stem 44, and pressure blocks 62 and 66 also movedo w'n with the head 43, and a bottle 80 having been placed on the adjustable stand 81-, the auxiliary head 66 will come in contactwith the top surface 83 of the bottle cap thereupon firmly seating the same on the bottle. As tho plunger continues to descend, the crimping projections-52 will contact with-the upper portion of the flange 84 of the bottle cap, and be forced outwardly against the tension of the slitted spring portions 85. into which the tubular capping member 49 is divided. These crimpmg projections 52 .will accordingly wipe e down along the flange 84 stretching t metal and taking up any slack so to speak that might be formed owing to the metal buckling or bending away from the bottle,

, and after the lower edge of theshoulder on the bottle head has been passed the spring tension of the said parts 85 will cause the said crimping projections .to snap the stretched metal inwardly and under the said shoulder, thereby causing a firm and tight hold between the cap and bottle. In the meantime, the head 62 will have been brought down in contact with the auxiliary head66, the spring 68 and 70 will have been compressed, and the upper edge of the bottle mouth will be forcedinto or will firmly compress the cork .87 of the' cap, and thereupon makea gas tight joint of great eflieiency, as will be clear-from Fig. 4. The projection 75 on the auxiliary head may be employed to depress the metal as illustrated, and theoretically at least, to increase the efiiciency of the seal, but in practice seals of very high efiiciency have been made without this projection. 'The pressure of .the heads on the top.83 of the cap effectually prevents the metal. from buckling in that part of the cap, and therefore,'aids the wiping and stretching action of the crimping projections 52.

In theoperations above described, as the parts descend the weight 73 causes the lever 56 to turn on its pivot and to bring its cam 74 into the position shown in Fig. 4 wherein it rests-on the cut away portion of the stem 44, and locks the parts against rising,

in their lowered positions. As, however,

under their spring tension and thereupon stripping off the cap. As the parts c011- tinue to rise after the capping operation is.

completed. the lug 72 turns the lever 56 in the opposite direction, thereby raising the weight and permitting the spring 68 to restore the parts to the positions shown in Fig. 3, wherein the spring 70 counterbalances the weight 73, and wherein the capping head and crimping projections are ready for another operation. As the shaft continues to revolve during the downward operation of the parts above described, the pressure between the pawl 17 and the toe of the trigger increases by reason of the resistance of the bottle and if these parts not sooner released from this or other causes when the lower surface of the cross head ll, contacts 'with the upper surface freeing the arm 36 and rod 42 from the in fluence of the shaft. The spring 44, after having been compressed serves to raise the capping mechanism into the position shown in Fig. 3, to return the arm 36 and lug 39 to their normal positions, and the spring 18 serves to snap the pawl 17 back into engagement with the trigger 22, thereupon bringing the projection 17 into the prope position to again engage the lug 3).

From the above it will be evident that the parts will 'repeat the above cycleof operations as long the pulley 1 is connected to the shaft 2, but as soon as the rod (3 is permitted to rise under the influence of its spring/1' shaft theoperation of the capping mechanism ceases.

It is evident that changes in the details of construction and in the operation of the parts as described may be made by those skilled in. the art without departing fromthe spirit of my invention, and, therefore, I do not wish to be limited to such features except as may be required by the claims.
