G. N. BAER I CAP FEEDING SLIDE May 18, 1954 Filed June 13, 1951 2 Sheets-Sheet 2 ATTORNEY Patented May 18, 1954 UNITED STATES CAI FEEDING SLIDE Application June 13, 1951, Serial No. 231,399

12 Claims. 1

The present invention relates to a cap feeding slide, and is primarily concerned with the provision of means for facilitating and improving the application of closure caps to receptacles as such receptacles move serially past a capping station. The invention finds its primary utility. in the application of metal foil caps to milk bottles or similar receptacles, and therefore it has been illustrated and will be described in that environment, though it will be readily recognized that it may fnd utility in other relationships.

The primary object of the present is to provide means whereby such caps, delivered successively to a capping station, past which receptacles move in a series upon a conveyor, or the like, may be brought into accurate registry with such receptacles, even though the receptacles may not be accurately aligned as they, approach and pass the capping station. Further objects of the invention will appear as the:

description proceeds.

To the accomplishment of the above and related objects, my invention may be, embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that change may be made inthe specific construction illustrated and described. so long as the scope of the appended claims is not violated.

Fig. l is a perspective view, more or less diagrammatic, of an embodiment, of my invention.

in operative relation to a conveyor upon which milk bottles are moved serially past the device of the present invention;

Fig. 2 is an enlarged front elevation of the feeding device of thepresent invention;

Fig. 3 is a side elevation thereof;

Fig, 4 is a rear elevation thereof; and

Figs. 5 and 6 arerespectively rear and front perspective views of the device of the present invention.

In conventional practice, receptacles to be closed by are carried, in serial arrangement, past a delivery chute through which caps are delivered, in succession to be applied to such receptacles, respectively. In Fig. l, I have shown a rectilinear conveyor it, but it will be readily appreciated that a star wheel or rotary conveyor of any'typemay be substituted therefor. As shown, filled milk bottles I i are carried in succession upon the conveyor it; but, in accordance with conventional practice, the conveyor ii) has a lateral dimension somewhat greater than that of, an individual bottle, so, that thfiabQttlES mayv bearranged mill; bottles or other invention foil caps, or the like,

as shown, upon said conveyor in rather hetero? geneous misalignment, A 1111 it at the mouth of each bottle is adapted to receive a cap it which, as shown, comprises a disc-like body i l with a dependent skirt or flange It. The caps are so proportioned that, when a cap is properly deposited upon the lip l2. of a bottle, its skirt will loosely encircle the bottle lip, and said skirtwill subsequently be shaped to grip the bottle lip firmly to hold the cap in place thereon.

At the cap applying station, 'a slide it leads caps, in single file, to a delivery chute indicated generally by the reference numeral ll. Conventicnally, such chute comprises a body l8 formed to provide a passage iii, so dimensioned as to receive caps i3 successively and hold them in, serial. arrangement. A cover plate it closes the front side of the passage [9; and, in the illustrated embodiment of the invention, that edge of the chute with which the slide it registers is left open as atZ i. Means,.such as'a coiledspring 22, having its lower end anchored to the ohutahas its upper end 23 anchored at 2 1 on the slide It to close that portion of the edge 2-! below the slide it. The lower endor delivery mouth 25 of the passage is is laterally; enlarged to compensate for misalignment of thebottles H with respect to the chute passage I9.

On the rear surfaceof the body 13, a wiper gate 26 is hingedly supported upon a bar 21 supported in brackets 28, 28 at opposite edges or" said body; and a coiled spring 23 resiliently holds said gate in its solid-line position of Fig. 3, for a purpose later to appear.

A retainer member as is supported at the;

delivery end of the chute i'i, said retainer memher being formed with a. passage 3i The upper end of said passage 3% is constantly in registry with the mouth 26 of the passage l9; and said member is formed to provide downwardly-converging lips 32, 32 whose adjacent edges are spaced apart by a distance minutely less than the diameter of a cap skirt it so that,

as a cap moves from the chute it intothe-passage 31-, it'will be caught, upon the lips 32, 32', and

lightly frictionally held in the position illustrated in Figs. 2 to 4.

In this position, the lower portion of the cap projects into the plane of movement of the lips.

i2 of the advancing receptacles.- it so that, if a. bottle lip moves will engagezthe. flange I5 to extract the cap from; the retainer member edge of the cap will fall, under such circum therethrough.

past the chute iii in proper alignment with the-cap so supported, such lip 12;

36. The upper, trailingstances, over the trailing portion of the bottle lip 12; and the wiper 26 will be swung, in a counter-clockwise direction as viewed in Fig. 3, to its dotted-line position in that figure, so that, as the bottle moves past the Capping station, the wiper will tend to press the cap into place on the bottle mouth in a manner well understood in the art.

If, however, such an advancing bottle is not properly aligned with the cap [3, in conventional structures, the cap will not properly fall into place on the bottle lip, and the bottle may pass the capping station without being properly capped.

According to the present invention, a bar 33 is secured to the front surface of the retainer member 36 by screws 34, or the like, and said bar is slidably transversely movable in brackets 35, 35 secured to the forward face of the closure wall 29 of the chute i1. Said brackets are provided with rearwardly-extending toes 36, 36 upon which the retainer member 33 is slidably supported. A cam element 31, having divergent wings 38, 3B, is suitably secured to the forward face of the bar 33; and it will be perceived that said wings 3B, 38 are provided with downward projections 33, 39 intersecting the plane of movement of the bottle lips l2.

Remembering that the cap i3, ready for delivery to a bottle, is supported solely within the retainer member 38, it will now be seen that, if a bottle approaches the capping station upon a line laterally displaced from central register with the cap currently supported in the retainer member 3d, the bottle lip will strike the projection 39 of one or the other of the wings 38. The inclination of said wings with respect to the line of travel of the bottles is such that, as a bottle strikes and moves past one of said projections, the retainer member 36 will be bodily cammed laterally to bring its retained cap into accurate registry with the line of movement of the currently-coactive bottle, whereby, as the bottle passes between the projections 39 of the wing 38, the currently presented cap will be properly deposited upon the bottle lip.

I claim as my invention:
