ried away from the machine to a'predetermined desired point. A

'lhe object of the invention is to provide a ,machine of `this class which can be more easily and `cheaply constructed than devices heretofore i'n use, which is very satisfactory and eiicient in operation,'and which is not liable to get out of order.

The invention lconsists'in means for attaining the foregoing objects, comprisin A among others: g Y A device Afor carrying bottles in inverted Y position through the. washing mechanism and then safely reversing theirposition as they. are placed upon a conveyor which'takes them away from the machine; in specific 80 means for positively and accurately feeding the bottles in a step by step motion to the washing Vmechanism,l and for positioning them in that mechanism; in means for safelly landing' a bottle being turned from in-v verted to uprightv position `upon a' carrier mechanism adapted to convey it away from the machine; in `mechanism for rendering Y the latter. mechanism safe so that it does not crushbottles being delivered to it, even 40 should there be an obstruction to its'operation which would, underother conditions, cause a bottle being operated uponto be crushed; means for adjusting themac'hne so as to handle bottles of dilerentsizes with- '45 out changing the principal of the device; a can'ier belt for transporting bottles through the washing mechanisms,

i which .insures each successive group of bot- 'tles carried'rbyit being in the same horizontal'position as they pass under the wash- .xringidevllcegs-ifa novel feeding-mechanism for moving suc groups of bottles onev after the 1922. Serial N'0. 576,196.

, The magma@ jf ai@ drawing illustrating this invention issupportedfrom the Hoor 18 by a framework, including a plurality of

upright standards

20, 2l, 22,23, 24 and 25 connected together longitudinally of the machine by a plurality of suitably arranged

horizontal members

26, 27, 28, 29 and 30, and suitably cross-connected as is necessary by horizontal members, such as 32, 33, 34 and 35. Suit-v ably journalled at the right-liand or front end of themachine, as shown in Figures l yand 2, are two transverse shafts, 36 and 38,

each carrying at its opposite ends a sprocket Wheel-40, adapted to receive and drive the links 42 of parallel sprocket chains, arranged as shown in the drawings, with the main or extended portions of the chains in horizontal position, within a tunnel-like cover 44, rising from the upper longitudinal frame members or table top 46, carried by supports 24 and Each alternate link 42 of these sprocket chains is provided with a horizontally extending bracket 48 in alignment or register with the corresponding bracket on a link on the opposite sprocket chain so that the two chains may be connected together at alternate links by means of bottle carrying bars 50, preferably channel shaped, each detachably secured in place by a bolt 52 passing through the end of the bar 50 and the adjacent bracket 48, and entering a little truck frame 54. These frames are provided with suitable anti-friction devicessuch, for instance, as rollers 56, adapted to travel ou suitable horizontal track rails 60, rigidly supported, between the sprocket wheels by any suitable means-as, or instance, uprights 62, carried by horizontal cross-trame members, such as 33.

Each bar 50 is provided along its length with a plurality of spaced perforations 64,

entering outwardly flaring conical bottle receivlng cups 66,. preferably but not necesa set of these nozzles 72 is mounted at proper intervals along a cleaning liquid, usually water, supply pipe 76, extending transversely of the machine and of the path of travel or the bar carrying 'sprocket chains, and a corresponding set of the air nozzles 74 is mounted in a similar compressed air pipe 78, parallol to pipe 76 and spaced just a sufficient distance therefrom so that when a given bottle carrying bar is moved one step, to be l special positive acting step-by-step motion,

retenes hereafter described, through the machine, it will travel from exact register one set of nozzles 72 to the adjacent set of naazles 74. So far as the principles oi" the machine are concerned, cleaning liquid, nsnaiiy water under pressure, may be suppiieii pipe 76 from any suitable source oi snp: and compressed air may be correspending f supplied to pipe 78.

In the particular case illustrateolin Fi ure 3, cleaning liquidunder pressure n supplied to pipe 7 6 via pipes 80 and 8' an external supply pipe 84, eontroiierL e valve 86; or, it may be Jfurnished by a ret is pump 88 operating through ,an apen c trol valve 90 to draw liquid via pipes and 94 from a drainage tank @t5-located the bottom of the machine and adapted Le ceive the cleaning liquid which passes it from the bottles 70, after it has forced into the bottles from nozzles 72. der the last conditions, a valve 98 bei? tank must be kept closed, instead of be open to1 the sewer or the like, as inns when the source of supply is direct pipe 84. ite-pumping of cleaning l from tank- 96 will only take piace when a cleaning liquid-as, for instance, a chemicai one of considerable value is used and s therefore desirable to obtain ull vaine the chemicals. When plain water i pressure is used, the usual practice wi to open valve 86, close valve 90, 'open i 98 and let the water flow `freely, pimp- 88 neing under these conditions at rest..

As the machine is intendeo to incne, when desired, exterior'cleansing of the bottles as well as interior cleansing, the 82-heretofore referred to-is extend to a horizontal pipe 100 extending througn the cover 44 and over the row o: hotties 7G, which happen to be in register with nozzles 72. ln pipe 100, immediately over the 1 of bottles 70, are a pluralityT oi3 disc nozzle perorations 102, preterabiy but not necessarily enclosed with a guiding hood 164, so arranged that cleaning liquid' deli ed from these nozzles will, as shown in Figeres 3 and 9, forcibly* strike and washtiie entes rior surfaces of the row of bottles which being washed internally by the sprays of Vliquid from the respective nozzles 72. The

nozzles 102 receive the same kind of cleaning liquid under pressure, viz, direct water pressure, or liquid returnfrom tank 96, as is passing through nozzles 72 into the bottles. ln order to blow compressed air into the bottles expeditiously, it is necessary to provide accurate means -for rst registering a given group of bottles on a suitable set of nozzles 72 and then moving them 'into accurate register with the corresponding set of air nozzles 74. ltn'order to insure such movement of the bottle carrying bars 50, a 3

menaces I device has been invented which will now be described. The mechanisms referred to are in duphcate, one at each side ofthe machlne operating on adjacent ends of bars 50. 'As they.

are, exceptfor position, alike, only one will be described. v Horizontally reciprocatable longitudinally of the machine, adjacent to the ends of the bars 50 in

suitablesupports

106 and 108, is a horizontal shaft 110, having pivoted to it, at its left-hand end, as Yshown in the drawings, a connecting rod 112, driven through an eccentric band 114 b an eccentric 116, carried by a transverse S aft 118, extending across the machine and suitably journaled by conventional means, this shaft being constantly driven by any suitable means, as for instance, gear 120, worm 122, belt 124, an

attached parts.

electricmotor 126 receiving electricity in conventional manner from a source not shown. v y

Connecting rod 112 is provided intermediate of its length with alconventional form of yieldingmechanism, specifically a spring 128, interposed between a block 130 on the end of rod 112, proper, and a. cross-head 132, carried by parallel rods 134 from eccentric band 114, the resultjbeing as well understood in theY connecting rod art,1that the rotationof eccentric 116 drives connecting.v rod 112 and attached parts to reciprocate rod 110; butthat, if an obstruction is en countered by 110, spring 128 will permit the reciprocation of cross-head 132 along rod 112 'againstl the action of spring'128, thereby `preventing injury to rod 110 and Rising rom fixed support 106 is astationary vertical pivot 136 on which a lever arml 128V is laterally rockable. Rod 110, which reciprocates through fthe bottom of this support 106 and through the axial line of this pivot 136, has rigidly attached to it beyond this pivot, to the right as shown in the figures, a, fixed cross-head 140, carrying a vertical pivot 142'on which another horizontally rockable arm'144 is journalcd.

v The outer or free swinging end of arm 138 is provided'.with 'an enlargement which loosely encloses arm 144 so that the latter arm can slip through the enclosing means on the end of arm 138. In the particular case here illustrated, this enclosing means A consists simply of two-pins 146, joined by a link 148 which passes over the arm 144 and fits loosely enough thereon so that the arm 144 can slide and between the pins 146;

Arm 144 is providedatftsV swinging end with ahook 150,-"

The outer free swinging endof'arm 144 is `also provided with an angular cam face 156 adapted to engage and operate upon successive bolt ends 52. -ln Figure 6, the forward tip end of the cam is shown engaging a particular bolt end 52a. In this particular case, movement of rod 110 to the right (as viewed in Figure 6) carries the arm 144 to the right from the position of Figure 6 toward that of Figure 2, and the engagement of camv face 156 with bolt end 52a forcibly moves arm 144 and consequently arm 138 downward, as

viewed in Figure 6, to release the particular.

bolt 52, engaged by hook .150 in Figure 6, and move arm 138 out of its path of travel when itsubsequently begins to move to the' left. At the end of this movement of shaft i 110 to .the right, hook 150 engages bolt 52, andas shaft 110 begins'to move to the left,

it pulls bolt 52a and its bottle carrying bar 50 to the left-unobstructed by arm 138. Bolt 52a, and its particular bar 50, can therevfore by a single rotation-of shaft 118 be ico tudinal travel of the bolts 52, ,thereby insur- Y ing engagement-of hook 150 with a bolt 52 whenever the position of thecam 156 will permit it. d Y

In the operation of the mechanism thus far described, Shaft 118 andeccentrlc 116 rotate continuously'to reciprocate rod 110 to thereby in the manner.v described

cause Vthe arms

138 and 144 to engagesuccessive bolt ends 52 -and thereby move the bottle carrying bars 50 in a step by step motion tothe left, 'as viewed' in Figures 1 and 2, first between nozzles V72 and 102` and then over' nozzle 74.

by an operator who stands at the frontend and, from'a suitable source of supply," loads each bar as it comes up to the top of the ad` jacent sprocket wheels 40 by placing a bottle v inv each of the bottle receiving cups 66 carried by that particular bar. VAs the bottles Ymove tofthe left, through the machine beyond nozzles 74, any cleaning liquid within them, which has not beendrlven out by the 'lv compresed airdelivered by nozzles 74,

out vof them through perforation 64 into 'the bottles arel carried 1in a. successivesteppby step motion toA the left until, as the chams pass over left-hand v rocket wheels 'of thenozzles 74, the L Y The bottles are supplied the machine F15.

through the path indicated by successive' positions in Figure 8 onto the delivery conveyor mechanism 160 which carries them through a drying room or compartment 162 where they are heated by anyY suitable meansas for instance, coils 164, before being tinally manually removed from the machine. The particular conveyor mechanism 160 may be of any conventional form driven by any suitable means and its details are therefore not shown in the drawing, except one pulley 166 which conventionally supports it.

The washing and draining operations heretofore described require that the bottles be carried as shown in inverted position, viz: lVith the bottle necks downward; and, sin'iilarly, it isdeSirable-if not absolutely necessarythat the bottles be right-side up in passing through drying chamber 162, and the bottles cannot be allowed to fall freely from the washing conveyor mechanism to the drying conveyor mechanism: first, because there would be great danger of breaking bottles; second, because they would not position themselves in any suitable manner on the drying conveyor. Means are therefore provided for especially guiding and. controlling the bottles as they fall from the washing to the drying conveyor. For this purpose, a plurality of inclined chutes 168 are provided-one in the path -of each bottle which is to be delivered from the bottle washing mechanism. Tn the particular case here illustrated, they are rigidly secured to cross-bars 170 on the frame of the machine, preferably but not necessarily made adjustable with reference to the side frames of the machine, through pin and slot connections 172, so that they may be selectively positioned below the left-hand or delivery end of the bottle washing conveyor mechanism. To insure the passage of bottles down these chutes 168, guard plates 174 are suitably secured at opposite ends of the row of parallel chutes 168.` Any suitable means may-be used for securing these devices in position. The chutes 168 and the guard plates 174 form three sides of a pas.- sage down which thebottles move from the washing conveyor mechanism to the drying conveyor and, for safe handling of the bottles, it is necessary to provide a fourth side which will retain and 'protect the bottles, as they fall through the successive positions of Figure 8 to the conveyor 160 and then get out of the way of the bottles, so that they can be carried by the conveyor to the drying compartment; Tn the particular case here illustrated, this fourth side of the guiding passageway is an upright board or bumper 176, preferably faced with rubber 178 where it engages the bottles, provided with suitable guide cleats 180 forindividual bottles, terminating at their upper ends in an angularly disposed horizontal guide flange 182, extending above thel bumper proper. This bumper is sustained its lower end by a pair of parallel rods 184 pivoted thereto, the opposite ends of said rods being pivoted at 186 on frame members 26. The bumper 176 is supported at its upper edge by similar parallel rods 188 of less length than rods 184,l said rods being rigidly connected at their opposite ends to a shaft 190, journaled in suitable bearing blocks 192 on 11p-right frame members 21. Rigid With shaft 190 is an arm 194 carrying an adjustably positionecl counter-Weight'196, adapted to counter

balance rods

184, 188, and bumper 176, so that these latter parts may be readily moved between dotted and full line positions of Figure 8 as shaft 190 rocks as hereafter described.

Shaft 190 also carries rigid with it a broken lever of conventional form, comprising a short lever arm 198, rigid with the shaft, the same having an angular flange 200 which'overlaps and bears against a second or supplemental lever 202 pivoted to the first lever at 204 so that, assuming lever 198 is rigid, lever 202 can swing in a clock-wise direction, as viewed in Figure 8, away from flange 200; but is prevented by said flange from swinging in the opposite direction about the pivot with reference to the first lever. Suitably attached to supplemental lever 202 at a convenient point, as 206, is one end of a retractile spring 208 whose opposite end is attached-as for instance-li 1 means of bracket 210 to a stationary poin.l on the machine. These parts just described are so` arranged and disposed that this spring will normally hold the bumper 17 6 arid connecting rods 188--184 in their elevated or dotted line position of Figure 8.

Lever 202 is so positioned with reference to shaft 118 that it extends into the path of travel of a cam arm 214, carrying a cam wheel 216 adapted to engage the arm and thus at a predetermined point in the rotation of shaft 118 swing lever mechanism 198-202, and consequently the bumper mechanism mounted moving in unison therewith, from the dotted line to the fullv line position of Figure 8. y This cam mechanism 214-216 is so timed with other parts of the machine controlled by shaft 118, as heretofore described, that the bumper 176 will be in the full line position of Figure 8 just at the instant when a given bottle carrying bar 50 has reached the proper angular position lso that it is ready to have the bottles carried by it fall o' and pass down the chutes 168 to the carrier 160. This cam mechanismis also proportioned so that the tles into proper place in the chutes 168, whereupon it begins to move upward to the dotted line position` of Figure 8, thus leaving the bottles on the carrier 160 to be transrported into the drying chamber.

The bumper 176 does not move any bottle vertically but whena bottle is out of position, as shown in dotted lines. Fig. 8, the bumper in moving from dotted to full line position of that figure shoves the bottle over against chute 16S-thus straightening the bottle up while falling in the chute.

The rods 184 are purposely differentiated in length from the rods 188 so as to insure rapid movement of the lower edge of the` bumper away from tliebottles on the carrier 160 as the bumper moves upward to the position where it. entirely clears them so that the bottles can be carriedunder it by the conveyor 160.

By using the straight bumper 176 extending across the conveyor 160 and by providhand end of the machine, as viewed in Figures 1 and 2.

The lever 198-200 is made in the form of a broken lever so that if in case of accident, bumper 176 in descending from the dotted line to the full line position of Figure 8 strikes an obstruction-as, for instance, a misplaced bottle on conveyor 160, and would thereby be unable to move further without damage, the lever 202 can stillbe moved on pivot 204 by cam mechanism 114--116l to and through .the full line position of Figure 8 and back again into contact with flange 200.

In the complete operation of the machine, the motor-.126 is started, power from any suitable source (not shown) is applied tov conveyor 160, cleaning liquid is ladmitted from one source or the other to pipe 82 compressed` air is admitted from any suitable source to pipe 78. -Thereupon, the operator standing in front ofthe machine places a row of bottles to be cleaned on the ynearest horizontally disposed bottle carrying bar 50 and upon each succeeding bar as it reaches that position. The operation of the machine causes these loaded bars to move in a step by step motion, first to the

liquid discharge nozzles

72 and 102, then to the air discharge nozzles 74s,v and finally to the top of the chutes 168, down which the bottles are discharged to the conveyor 160, they being this movement st ead'iedand guided bythe bumper mechanism '176 which, after performing its function, moves up to the dotted line position of Figure 8 and allows the bottles to pass, first, to the drying chamber 162; and finally to the hands of operators who removethe clean bottles from the machine. p

The'bars 50 are each provided on one side with a horizontally extending flange 218, leaching sufhciently close to the next adjacent bar to aid in'spacing'the bars apart as they travel, loaded with bottles, along the tracks 60.

' spaced members along the conveyer, an arm pivoted to a fixed point beside the-path of travel of the conveyer with apart which can move into the path of the irst of said spaced members on the conveyer to temporarily prevent movement of the conveyer, a member reciprocablebeside the conveyer adjacent to said iirst swinging-arm, a second arm pivoted onv and carried by the reciprocable member having on its swinging end a hook for successively engaging the spaced members on the conveyer, means loosely connecting the two arms so the `second recipromeans andthe reciprocable member for the purposes set forth.

15. In mechanism of the class described, a conveyer to be moved step by step, two spaced members along the conyeycr, an arm piVo-ted to a fixed point beside the path of travel of the conveyerwith a part which can move into the path of the first of said spaced members on the conveyer to temporarily prevent movement of the conveyer, a member reciprocable beside the conveyer adjacent to said rst swinging arm, a second arm pivoted on and carried by the reciprocable member -having on its swinging end a hook for successively'engaging the spaced members on the conveyer, means loosely connecting the two arms so the second reciprocates with reference to the first as they both swing about their pivotal. points, a cam on the second reciprocable member moves the `second swinging,l arm past said second spaced member, the first swin'ging arm is moved laterally of the conveyer clear of the path of travel of the first spaced member thereon, vmeans urging the lswinging arms to engage the spaced members on -the conveyer,. power means continuously reciprocating the reciprocable member, and yielding mechanism between the power means and the reciprocable member for the purposes set forth.

16. In mechanism of the class described, a conveyer to b'e moved step by step, two spaced members along the conveyer, an arm pivoted to a fixed point beside the path of travel of the conveyer with a part which can move into the path of the first of said spaced swinging arm engaging the second spaced Y .member on the conveyer so shaped that as the members on-the conveyer to temporarily preoted on and carried by the reciprocable I spaced member on the conveyer member having on its swinging end a hook for successively engaging the spaced members on the conveyer, means loosely. connectin'g the two arms s0 the second reciprocates with reference to the first as they both swing about their pivotal points, a cam on the second swinging arm engaging the second so shaped that as the reciprocable member lmoves the second swinging arm past said second spaced member, the iirst swinging arm is moved laterally of the conveyer clear of the path ot travel of the first spaced member thereon, a spring between the reciprocable member and the second arm normally urging it toward the spaced members on the conveyer, power means continuously reciprocating the reciprocable member, and yielding mechanism between the power means and the recip- 'rocable member for the purposes set forth.

17. In mechanism of the class described, in combination with a series of members 52 to be-moved an arm 138 pivoted at one end to P a fixed point having at its other end an abutment 154 a'dapted to engage an adjacent one of said members 52, a. reciprocating shaft 110 adjacent thereto, a second arm 144 pivoted to the shaft having at its free end a hook 152 adapted to selectively engage Ione of said members 52to be moved, `a sliding connection between the ends of the two arms, a spring urging the arms to the side of the shaft and a cam on the end of the second swinging arm resisting said spring bv engaging one of said members 52, all the parts being arranged and disposed as shown and described for the purposes setforth.

18. In mechanism of the class described, a horizontally disposed conveyer carrying bottles .in inverted position, another lower horizontally disposed conveyer and means comprising an inclined chute and a reciprocable bumper facing the conveyer guiding bottles safely from the former conveyer to upright position on the second conveyer for the purposes set forth.
