Wis, assignor to Menomonee Falls,
This invention relates to bottle handling equipment and refers more particularly to a bottle carrying conveyer flight of the type used in bottle washing machines.
In view of the relatively great length of these conveyers, light weight construction is extremely desirable, and it is, therefore, an object of this invention to provide a conveyer flight of the character described which is fabricated entirely from sheet metal to obtain the desired lightness without sacrificing strength.
The conveyer flights with which this invention is especially concerned have bottle neck receiving sockets spaced along the length thereof and retaining means such as a sliding locking'plate operable to engage and hold bottles received in the sockets.
In keeping with the primary objective of this invention which is to insure lightness coupled with strength, it is another object of this invention to provide a novel manner of forming the bottle receiving sockets.
The conveyer flight of this invention follows past practice to the extent that it consists of an elongated tubular structure having superimposed top and bottom walls. These top and bot-.
tom walls have aligned holes for the reception of the bottle necks and carry the socket structures which serve to guide the bottles into position and hold them against excessive tilting. The means for releasably securing the bottles in their sockets is slidable within the tubular structure.
To insure adequate cleaning of the. neck portions of the bottles, it is necessary that the flight be cut away adjacent to the sockets so that water has adequate access to and from the interior of the sockets.
Inasmuch as the entire flight of this invention is fabricated from sheet metal, the ports or openings provided by these cut away portions are preferably in the side walls of the tubular unit. This, unless compensated for, would result in a weakened structure. To offset this possible weakness, it is a further object of the present invention to 50 form the sockets that the superimposed top and bottom walls are reinforced thereby so that the structure as a whole has adequate stiffness and rigidity throughout its entire length notwithstanding its cut away side wall portions.
With the above and other objects in View which will appear as the description proceeds, this invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described, and more particularly defined by the appended claims, it being under-' stood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.
The accompanying drawing illustrates one complete example of the physical embodiment of the invention constructed in accordance with the best mode so far devised for the practical application of the principles thereof, and in which:
Figure l is a View partly in section and partly in side elevation illustrating one end portion of a conveyer flight constructed in accordance with this invention;
Figure 2 is a top plan view thereof;
Figure 3 is a detail cross sectional view taken through Figure 1 on the plane of the line 3-3;
Figure 4 is a top plan view on a reduced scale showing a portion of a conveyer made up of the flights of this invention; and
Figure 5 is a detail cross sectional view taken through Figure l on a plane passing between the bottle receiving sockets of the flight.
Referring now particularly to the accompanying drawing, in which like numerals indicate like parts, the numerals 5 and 6 designate two conveyer chains each having rollers 1 adapted to run on supporting tracks 8, and links 9. Alternate links of the two chains are connected by the flights of this invention designated generally by the numeral l9.
Each flight It! comprises a substantially flat cross bar l2 having its ends welded or otherwise secured to brackets I3 which in turn are suitably secured to the links of the conveyer chains. This flat cross bar is stamped from a single sheet of relatively heavy sheet metal and has a plurality of holes 14 at spaced intervals along the length thereof.
Superimposed upon the flat supporting bar 22 is a complementary cross member It. This member is essentially a channel mounted on the bar [2 with its open side facing down so that its flanges l'i rest on the bar I2. intervals these flanges I! have rivet forming tongues I8 projecting therefrom to pass through slots in the bar l2.
The ends of these tongues l8 are riveted or swedged over as at I9 or spot welded to the' bar E2 to thus securely hold the channel and the bar l2 together and form a rigid flat tubular structure.
The web 20 of the channel has holes 2| in line with the holes Id of the flat bar. The edges of the holes M and 23 are extruded outwardly to form flared necks I l and 2|, respectively to which conical or funnel-like bushings 22 and At spaced.
23 are secured. These bushings coact with each other and the flared necks to provide bottle receiving sockets into which the bottles to be carried may be inserted in inverted positions as shown in Figure 1.
The bottles are held in place in their sockets by a latch plate or slide 24 reciprocable within the hollow flight. This latch plate may be of any suitable design or construction and in the embodiment illustrated consists merely of a bar of relatively heavy sheet stock having keyhole shaped openings 24 formed therein. The large ends of these keyhole shaped openings, upon alignment with the sockets permit insertion of the bottle necks into the sockets or their removal therefrom, while the narrower portions of the keyhole openings are of a size to engage the bottle necks beneath their bulbous enlargements at their mouths. I
In the operation of a machine with which flights of this character are used the latch bar cated from sheet metal, said bod structure having bottle receiving sockets at spaced intervals along the length thereof, each socket comprising a funnel shaped bushing having its small diameter end fitting into a hole in a wall of the body structure, the peripheral edge portions of the holes being extruded outwardly toward the large diameter ends of the bushings, and the small diameter ends of the bushing being flared outwardly over the inner surface of said extruded portions so that the bushings are secured in place While the wall in which the hole is formed is reinforced against bending stresses.
2. A bottle carrying conveyer flight 'for use in bottle washing machines and the like for carrying bottles by their necks comprising: a substantially flat bar having bottle neck receiving openings therein; a, formed sheet metal channel in superimposed relation with said flat bar with its open is shifted from one position to the other by suitable shifting means (not shown) engageable with a pin or boss 25 fixed to the latch plate and extending upwardly therefrom.
It is to be observed that the flanges I! which form the side walls of the tubular flight structure are cut away adjacent to each socket. This is done to asure free access for water and cleaning fluid to the neck portions of the bottles in the sockets to make certain that neck labels will be washed off. However, as will be readily apparent, this interruption of the flanges ll ad- ,acent to the sockets if not compensated for, would result in weakening the flight against 7 bending stresses.
The novel manner in which the bottle sockets :are formed offsets this possible weakening. The outward extrusion of the edges of the holesi4 and 2'! to form the flared necks stiflensthe' web of. the channel and the flat bar l2 and inasmuch as the diameter of these flared necks is large enough to span the space between adjacent sections of. the side wall forming flanges Hit follows that these flared necks coact with the flangeportions to. provide stiffness and rigidity for the entire length of the fligh Reinforcement is further provided by the manher in which the bushings 22 and 23 are attached. like bushings as clearly shown in Figure 3 are The small diameter ends of the funnelflared or rolled out over the inner surfaces of.
the extmdedv flared necks. added rigidity is obtained While In this manner, at thesame time bushings aresecured in place in an exceed ingl'y simplemannen: I, I
In keeping. with the spirit of this invention the rollers 1 are. also formed of sheetmetal. They consist of two identical stamped cup shaped units 7 2B welded together back' to back, the hubs for the wheels, like the rims, being formedby int'egral annular flanges.
. From the foregoing description taken in connection with the accompanying drawing-it will be readily. apparent to. those skilled in the art that this invention not only provides an exceed- .in'gly light andstrong bcttle'carrying flight structure suitable for bottle Washin machines, but.
that it likewise effects substantial economy in cost of manufacturing, flights of this character. What I claim as myinvention' is: g g l. A fiight for bottle carrying conveyers and the like'comprising: ,an elongatied. tubular bodystructure composed of connected pieces fabri- I outwardly;
