' 9 Claims. (01. lee-#31) v The present invention; relates to an improved device for uselwith conveyoriisystems of. the type extensively employed in bottling, canning, and siinilar industri'es; The invention is' primarily designed for mfromone station be cansor the? like; traveling lines eachleading to divided into two separate another station:

Granted to me on July Patent N'oi 2,515,8'7 1i covering an automatic dividing device for attaining such objectives. However, the: device disclosed. in: said patent necessarily requires the presenceof an air pressure system in the plant-since the-.1 operatingmechani'sm includes a rot'ary valve and apair of diaphra'g-ms actuated bycompressed-air. a

Most of the larger plants are equipped witha compressed airsystem and-under those circum- I stances; my patented device has b'eensfoun'd to achieve its objects in a most efficient manner.

However, many ofthe smaller plants, are not equipped with a compressedair system, so that installation of my said device: would also entail 1 8, 1950; were Letters I 1 corporation in that type-of conveyor system wherein -it is requisitetha-t asingle' line of bottles,

With particular'reference to Figs. 1 and, 2,

numeral-2B designates a standard. endless conveyor, only the delivery or discharge end of which is portrayed. The conveyor. travels in the'direction indicatedb'y the arrows d, and-may be driven by power appliedto shaft 24, or otherwise, asjis understood. I

, For explanatory purposes, it will be'assumed that conveyor 20, is'part. of a system for conveying bottlesti'n a single line from one station of a bottlingjv plantfto a. division point, where the single line'isi'divided into two separate lines each lead- It is to be understood however, that the inventibn is not restricted to bottle conveyorsys- Fig.2: i's sidefelevationahviewi of Fig. 1', with guidezrailcelement's omitted}, v

. Fig. 6 is a top plan-viewi or the device,with

tems, but that it may be employed with equal'efricien'oy in other analogous conveyor apparatus.

That-is to s'ay',the bottle conveyor system illust-rated in exemplary only, and the invention could beincorporated in any conveyor system wherein itis' desired to divide a single line of articles traveling onone conveyor, into two separate lines each traveling on another conveyor.

Reverting now to Figs. 1 and 2, bottles propelled forwardly in 'upright position" on conveyo'r 20 are indicated by broken lines and designated B;. Said bottles may be: spaced as shown; or oth'erwisa. itv being noted that the instant device is: so designed that its operation is not dependent upon spacing. In other words, the de vice will: operate regardless; of whether the articles on conveyor Zll are evenlyor unevenly spaced; or whether they are in physical contact with-oneancther.

: Overlapping. the discharge end of said con- Fig. 12 is ahead view of saiddeflector plate,

The conveyors 26 and '28 respectively, also have similar guide rails 34 and 36. along theiri marginal edges, the inner rails in both instances:

forming a continuation of guide rails provided On the dividing device, as will appear.

An angularly disposed guide rail SS-connects. one of said guide rails .32 with the outer rail 34, p and a similar rail 40 connects the other rail 32 with outer rail 36.

All of these guide rails are so spaced as to prevent the bottles from tipping as they travel on the conveyors, and during the time they arebeing transferred from the single line conveyor toeither of the conveyors 26 or 28, as is understood. I

Itis noted that the guide rails form noparof the instant invention, any appropriate rail construction of this nature being suitable.

Removably mounted on a standard 42 as shown, or on any other suitable stationary support adjacent the overlapping conveyor end portions, is'the divider unit comprising the present invention. It is generally designated by referencenumeral44. r iv r Included in this device is a substantially'rectangular housing or casing having a bottom wall 46, side walls48, a rear end wall 50, and a forward Wal152. V I

As seen to best advantage in Fig. 9, said forward wall includes converging portions 54 merg ing at their forward ends into a'substantially triangular'body portion 56, 'and at their rear endsin to the side walls 48. V c EXteriorly; each convergingwall portio n;54 is recessed as at 58 to provide a smooth vertical surface or slideway for a purpose to appear.

Secured to each side wall 59, as by countersunk screws 60 or the like, are upper andlower guide rail members62 and 64 respectively. The cross-sectional configuration of these guides, as best'seen in Fig. 10, is preferably semi-circular. As hereinbefore noted, and as portrayed in Fig. 1, the rails 62 and 64 are alined with inner rails 34. and 36, when the divider is properly installed. At theihfor'ward ends, the rail members. 62 and 64 are bevelled offas at 66, so as to merge into the outermost face portions 68 of the converging walls-54. In other words, as the drawings clearly-illustrate, rails 62 and-'64 combine with face portions 6-8 to produce smooth, continuous guides for the ware during the transfer operation as will be seen.

' :Furthenthe forward 'ends'oi said rail membersare cut away or recessed at 10, so as to provide clearance for a pair'of ware deflecting plates which, as will appear, are adapted to be alternately reciprocated horizontally along the SurfacesSB.

With particular reference to Fig. 9, each wall 54 is provided with an elongated horizontal slot '12, through each of which projectsa lug 14, slidable therein. Exteriorly of the housing; a deflector plate 16 is secured by a countersunk VII 4 screw la to one lug, and a deflector plate 80 is similarly secured to the other lug, as shown.

In Figs. 11 and 12, the deflector plate 80 is shown detached. It includes a body portion 82, an integral forwardly projecting upper finger 84, a similar lower finger 8B, and a similar intermediate flnger88. The extremities or said finers are roundedas at- 90, so that as willfappear,

should the bottles of the single line" be" in contact with one another, insertion between the leading unit and the next adjacent unit is facilitated.

The top and bottom edges of plate :80 are recessed at 92 so as to provide tongue portions '94 slidably mounted in longitudinal grooves 96 formed in the exterior face portions 68 of one converging Wall 54.

The plate 16 is similar to plate 80, and appears to best advantage in Fig. 5, where it is seen to includea bodyportion 98,. provided with tongue portions I00 along its top and bottom edges. Similar to those of plate 80, these tongue portions are slidably mounted in longi-; tudinal grooves 9'6 formed in the exterior face portions 68 of the other converging wall, 54.

' Integral with the body portion of plate 16, are a pair of forwardly projecting fingers I02, so spaced relative to the spacing of fingers 84,85 and, that the latter may freely traverse the former, and vice versa, when the-plates 16 and 80 are'recipr'ocated. The extremities, 'of fingers. I02 arealsorounded as atl04. .1 I The means for. alternately reciprocating the deflector plates will now be described, with,.par ticular reference-toFigsGand '7. r I Y Each of the lugs 14. is provided with a vertical threaded apeitd'reiOB-for the reception of a pivot screw. a

irNumeral H6 designatesa second link, the forwardwend. of whichis pivotallyconnected by. a screw 1 [8 to that lug which is secured'to deflector plate 80, and; the rearv end of which is pivotally connected to said rotary di-scby a pivot screw, I20.

, cWith:thisarrangement, it-should be obvious that counterscl'ockwise. rotary motion of disc: H2 will' cause deflector plate 16 to slide forwardly from the position it occupies in Fig. 6, to itsFig. .7 position. I Simultaneously, deflector plate will sliderearwardly from the position it occuples. -;in Fig-6, to its Fig. 'Iposition. r As seen particularly;:in.'Fig.=I8, dis'cVI-2 has a depending. hub portion I24, and is rotatively mounted ona stud l26,"the reduced threaded lowerend' of which'is in engagement. with the bottomwall 46.

Intermittent partial rotatio'n'ofthe disc. H2 .is effected by the alternate energization of a pair of solenoids -I-2 8 and I 30, each of which; is appropriately m'ounted within the casing on abracket secured to the" bottom wall 46, as shown. The solenoids are conventional, and each includes-re. movable armature l32 which is'pulled in when the solenoid is energized, and is free to be moved outwardly when the solenoid is de-energized, as is understood. i Outwardmovements of the armatures are limitedby enlarged headmemb'ers I 34 thereon and a rectangular opening- I36 is provided in' the adjacent side wall 50 to accommodate saidnlemestate-4 ass stant.a ibr id t iiii' t sd leverrpi otally-mo-untedon astudI-dflfas arly he"forward"end of said leverhasan elo-ngated "48- therein;- throughwliich passesl a screw threaded- -ar'ierture nub; engagement-wt provided m disc m,- An intermediatejpor'tion{of lever I38-fhas apivotal 'connection I 52- with a se pi o'tal conn ction l-i l with the pr:seen11 -critter th armature I32 associated witha solenoid 128i Aflrectangular opening I-=56 is rcviuea in' tlie a entside wall- 50 to accommodate these parts; From the foregoing-and an inspection of Figs.

'l-lowever, when arm I92 is in its Fig. 7 position;

rivet 202 is not in contact with said plunger so that the downwardly biasing means incorporated in the micro-switch closes the circuit" which ena ergizes"SOlenOidfI'ZB, as has been explained; a in One of'th'ei principal features ofthe invention is that each successive leading unitof the 'sin'gle 7 line-"of bottleswill swing arm I92 in -adirection opposite to that efiected-by itspredecessor:
