HUGH M. ROSS, OF WOODHAVEN, NEW YORK, ASSIGNOR T0 ADBIANCE MACHINE WORKS, INC., 01 BROOKLYN, NEW YORK,'A CORPORATION OF NEW YORK.-

BOTTLE-SEALING MACHINE.

Application filed September 28,1923. Serial No. 665,260.

My invention relates to bottle sealing machines. The principal object of the invention is to provide in machines of that; kind improved means for shifting the caps orclosures for the bottle or container tooperative position in the machine. In machines of this character heretofore constructed the caps are moved to position in the, machines by a spring pressed pusher which engages the caps with something of a blow, tending to deform caps and prevent uniformly satisfactory sealing of. the containers, especially if the cap is made of relatively thin material. One object of my 1nvention is to obviate this defect.

Other objects of my invention will appear more fully in the following detailed de 'scription and appended claims. I

The accompanying drawings forming a part of this specification illustrate one einbodiment of mechanism containing my invention.

In the drawings, 7

Fig. 1 is a front view of the mechanism.

Fig. 2 is a side view of a portion thereof.

Figs. 3 and 4 are sections taken on line 3-3 of Fig. 2 and showing the apparatus in different positions; and

Fig. 5 is a side view of the cap pusher.

Referring to the drawings, 1 the sealing head 1 is provided with a sealing gate 2 which is fulcrumed for pivotal movement about. the axis of the vertical shaft 3' into open or closed position. The gate 2 is splined to the shaft 3 as shown at 4 so as to rotate with the shaft 3. A coil sprmg 5 surrounding the shaft 3 and connected at opposite ends with said shaft and a relatively fixed part of the machine tends to rotate the shaft 3 in the direction to effect 7 the closing of the gate 2 against the head 1. -The machine comprises a relatively fixed housing 6 provided with a cam slot 7 in which is engaged a roller 8 carried by a collar 9 secured to the shaft 3. As roller 8 rises and falls in the inclined portion of the cam slot 7 during the operation of the.

machine, the shaft 3 rotates to effect the opening or closing of the gate 2. The opening of the gate is effected by the cam action on the roller 8 of the coacting wall of the cam slot 7, which action causes the shaft 3 to be rotated against the torsion of spring 5. To seal. the closure inlet, 10 when the .and out ofthe way of the chute.

fore the cap inlet 10 has been moved to reg:

ister with the closure chute 12, the gate 2 has, of course, been moved to open position When the retaining pawl 13 is elevated a closure enters the inlet 10 and bears against the liquid supply plunger 14. The cap remains in this position until the plunger 14 is elevated after the bottle has been filled after which the closure is thrust by a pusher carried-bythe gate to a position above the bottle and below the cap sealing throat 15. The skirt of the cap is adapted, upon further downward movement of the sealing head,

to be contracted by throat l5 about the rib V at the mouth of the bottle to seal the cap in place on the bottle. The apparatus described inthe foregoing detailed description is not per se new in this invention, For a more detailed description of the construction and operation of such apparatus, attention is directed to United. States patent to Calleson Reissue No. 14,657, dated June 10,1919.- i

The cap pusher herein disclosed so constructed and arranged that instead of striking the cap with a blow it engages the same with but. little impact and further tends to avoid deformation thereof by moving laterally thereof during its engagement therewith. Referring to the drawings, the pusher is movable horizontally in an exten sion 16 in the gate or closure 2, its path of movement being at an angle to the cap inlet 10. The pusher comprisesa forward cap engaging portion 17 and a'rear body portion 18 to which the cap engaging .portion 17 is pivoted for movement about a vertical axis, as shown at 19. A spring 20 bearing against the end wall of the extension 16;.of the gate or closure 2 and against the body. 18 of the pusher tends to move or maintain the ypusher so that the cap engagingv ortion 17 isprojected beyond the gate. he body pertain 1.8 of the pueher is formed to partly enclose the spring 2U.

111611 with thebody portion 18 thereof.

The outergor projecting end of the cap engaging portion of the pusher is provided. with a projection 22 which is arranged to. register with guide shown as in the form of a groove 24 in the bottom wall of the cap inlet 10 when the gate 2 is entirely closed, the groove 24 beingarranged so as to be under those conditions in alinement with the path or movement or" the projection 22; so that the pusher is adaptedlto force the cap inwardly of the head to its position above the bottle or container when the liquid supply plunger 14 is elevated in the sealing head. (See Fig. 4.)

In Fig. 3 I have shown in dotted lines the J position of the partsduring the closing of the gate at the time the pusher first comes into engagement with the sealing head. It will be seen that in this position the projection 22 is to one side of the groove 24. The

projection 22 is accordingly held by the ead from engagementwith the 'cap; andduring the further closing of the gate 2, the sealing head by its engagement with the projection 22 holds the pusher out of engagement with the cap and causes the pusher to be retracted into the housing 16 on the gate 2.' When the gate is entirely closed the' projection 22, having moved laterally towards the groove 24 during the closing of the gate 2, registers with the said groove. The pusher at that time engages the cap, having moved gradually in its lateral movement with respect to the groove 24 into engagement with the cap.

Referring to Figs. 3 and 4'it will be seen that as the cap is moved inwardly by the pusher, the cap engaging end of the pusher moves laterally or horizontally with respect to the cap so thatinstead of exerting all of itspressure'in a thrust directly upon one point of the. cap the pusher applies its pressure to the cap in a combined lateral and forward movement The result of the ahove coaction of the pusher with the cap is to move the latter into position above the bottle cap or seal without'tlieobjectionahie deformation of the cap.

s As the groove 24 is not equally distant.

at every point from the axis of the'shaft 3, it is necessary that the projection 22 on the cap engaging portion 17 of the pusher be capable of yielding laterally with respect to the gate 2 when the gate is-ope-ned. This lateral yielding is permitted by the pivotal mounting of the portion '17 of the pusher with respect'to'the body'of the pusher; so that upon opening ofthe gate the portion 1? v of the pusher can yield; laterally to permit the projection 22 to pass freely along-and" outof the groove 24. The portion 17 of the pusher.

' the desired lateral movement thereof ith out binding against thegate 2 and without obstruct-ion from the portion" 18 I of the 7 It is to be understood that changes and modifications may be made in the device shown and described without departing rom the spirit of my invention andlthe scope of the appended claims.
