LAUNDRY-DISTRIBUTING APPARATUS.

Application filed January 12. 1926. Serial No. 0,752.

The present invention relates to automatic di Vribiitinfr and t'eeding laundry apparatus, particularly tor use in connection with a (lat work ironer. and has for an object to provide silrli :ipiiaratus adapted tribe eniiloved in such relation to the ironing niailiiiie as to greatly add to its etiiciency and cailmcity.

The method hereto tore employed for feeding articles of laundry to an ironer consisted ini manu-,illy placing the articles upon the moving apron ot the, ironer, several operators being usually employed tor this purpose. and who stand in tront ot the machines as it is continuously operating and place the articles in tlat relation iipon the moving apron. This method, however, required that the operator work with great rapidity in order to get as many articles as possible iii place upon the moving apron, and ifirecl'uded very close or precise placement ot the pieces. with the result that they were very otten wrinkled or vfolded as they moved into the iroiier, and much ot the ironing space was not utilized. inasmuch as the articles could not be placed to the best advantage in the time, allowed. lt was therefore impossible to opi-irate the ironer continuously and with full efficiency. v

According to the present invention it is proposed to provide a distributing and feeding apparatus in which the laundry pieces niav tlrst be ted selectively by hand at a speed independent ot' that ot the ironer. and thereupon automatically ted to the ironer in synrlironisni therewith in a uniform and etticient manner. and at such vtull speed ettieiencv as would be impossible with the previoiisrmetliod ot teeding directly to the ironer le: hind.

i 'li propof-ed one adaptation et the invention to provide a series ot machines arranged in cooperative relation with a coniiiion conveyor extending to the ironer, certain machines adapted to hive laundry pieces .ted into them by the operators and stored preparatory to automatic feeding to the iroiier. while other machines previously loaded are being operated to auton'iatically 'i'eed to the ironer. Thus the ir-oiier may be eontiiiaoiislv operated when desired at its tiill speed efficiency.

lt is iiirtlier proposed to provide such machines in direct lino with each other. and which may be selectively operated to feed laundry to a conveyor moving beneath all of such machines, so that the machines need not be .moved into or out of relation with the ironer. hat will remain stationary, and through the common conveyor will he operatively related to the ironer.

lllitli the above and other objects in view, an enihodiiiient et' the invention is shown in the .accompanying drawings, and this einpodiment will be hereinafter more fully described with reference thereto, and the invention will be linally pointed out in the claims.

In the drawings Fig. 1 is an elevation ot one end of a aiiiidry distributing and feeding machine, according to the present embodiment of the invention, and with the parts in position for auton'iatic Yfeeding to the ironer,

Fig. 2 is :in elevation of the other end of the inachiin;

Fig. El is a top plan view thereof;

Fig. l is an elevational view showing a series ot' the machines in relation to the comnion conveyor tor carrying laundry to the ii'oncr, one ot the machines being shown in position tor automatically t'eeding to the ironer. and the other machine being shown in position for having laundry fed thereto by the ol'ie-rator preparatory to being ted to the ironcr, and

Fig. 5 is a side view of the ironer conveyor mounting at one end of the series ot machines.

Similar retercncc characters indicate corresponding parts throughout the several tigiires ot the drawings.

Referring to the drawings, the machine according to the present embodiment ot the invention comprises vertical side frames l() oi substantially rectangular shape and provided centrally with vcrtiral slidcways ll in which apron roll supiliorting slides 12 are engaged for vertical sliding movement. and whcli are provided at their corners with antifriction wheels 1? engaging the side flanges ot the slideways. lliitliin the slides l2 there are joiirnaled the sliatt ends ll ot the lower apron roll l5, the apron 1G being sccui'ed aty one end to this roll and extending therefrom first over an idler roll 17, joiirnaled at its ends in the side trame 10. at one side thereot ana slightly above the common ironer conveyor. hereinafter more fully described. The apron is then carried upwardly and over a feed roller 18 and from this roller in upwardly inclined relation over a feed roller 19, from which latter roller it extends to the upper apron roller Q0, the shaft ends 21 of which are journaled in roller-ed trucks 22 slidably supported upon upwardly inclined tracls secured at their lower ends to bracket portions 24- of the frames and at their upper ends to upwardly inclined eXtension arms Q5 formed integrally upon the rearward upper corners of the frames. The apron 16 is adapted to be wound from one roller upon the other: being wound from the lower roller to the upper roller during the operation of manual feedingV of laundry to the machine, and during which operation the upper roller rests upon the feed roller 19 and is rotated thereby, while the lower roller is raised with respect to the irouer conveyor. ln the operation of automatically feeding to the ironer conveyor, the apron is wound from the upper roller to the lower roller, carrying` the laundry stored upon the apron about the upper roller to the ironer conveyorr` the lower roller being in contact with the ironer conveyor to be rotated thereby, while the upper roller is raised with respect to the fer-d roller 19.

As previously pointed out the series of machines are arranged in line with each other above the common conveyor extendingr to the ironer, and at the forward side of each machine there is provided in spaced relation above such conveyor a platform 26 upon which the operator may stand during the operation of feedinO laundry to the machine. T he ironer Q7 is shown at one end of the series of machines.

The ironer conveyor apron consists of a series of endless tapes 28 extending: at one end about a small roller Q9, disposed above the upper roller 30 carrying the feeding apron 31 of the ironer, and in downwardly inclined relation from the roller 29 about a roller 32 journaled in the side frames of the first machine, the upper traverse of the apron Q8 being held in engagement with the upper side nof the roller 32 by means of an endless apron 33 extending about a roller 34 having its shaft ends 35 journaled in vertical. slots 36 in the side frames 10 directly above the roller and over a small roller 3T journaled above the roller 2f). This apron 3S is adapted to move with the conveyor Q8 be tween the rollers and 29 to retain the laundry pieces in flat relation upon the conveyor until they pass over the roller 29 and into the ironer. The conveyor extends from the roller 32 in horizontal relation beneath the several machines to a roller 38 disposed beyond the last machine of the series and mounted for horizontal compensating;l adjustment movement in a bracket 39.

In passing through the several machines the conveyor engages above and below spaced horizontal rollers 40 and 4.1 jeurnaled in the lower portions of the frame 10 of each of the machines, and which rollers are positively driven, as will presently more fully appear, for the purpose of drivingr the conveyor.

ln the last machine of the series there is provided a tension roller over which the lower traverse of the convey r passes and which roller insures a p sitive engagement of the conveyor with the feed rollers 40 and 4:1. As before pointed out` the lower apron roller 15 of the machine is adapted to be lowered into engagement with the conveyor duringr the automatic feeding` to the ironer, the saine being shown in this position in the left hand machine. Fig. Al, and in which posi tion the said roller rests upon the

rollers

40 and 41 depressing' the convevor beween these rollers. The conveyor pa. es in flatwise relation over the rollers in the raised position of the lower apron roller, as indicate(L in the right hand machine, during the manual operation of feeding clothes into the machine.

For the purpose of taking' up slack in the conveyor when the same is moved into flat position after having been depressed by the lower apron roller, and thereby maintaining a positive engagement with the feed rollers 40 and Llil., the roller 38 is adapted to yield in a horizontal direction, an outward pull beine` maintained thereon to take up any slacli in the conveyor by means of a drum 43 supported .in a suitable bracket 44 and to which one end of a cable 45 is secured, said able passing beneath a roller 47S and over a roller 47 and being provided at its other end with a weight 48 which tends to turn the drum in counter-cloclrwise direftion. The shaft 49 of the drum is provided with a gear 50 meshingr with a raelc 51 mounted for hori- Zontal sliding movement and to the end of which the adjustable roller 3S is rotatabl` secured; thus rotation of the drum 43 through the action of the weight 48 will impart an outward movouunt to the roller 38. while an inward pull by the co veyor upon the roller 38 will lift the weight.

The rollers Il() and Al-l are adapted to be driven directly from the ironer in synchronisin therewith and for this purpose a gear driven bv the iioner, connected by a sproclct chain with a rear 54 mounted in a suitable bearing bracket and havingr a spir f' p al gear u secured upon its shaft which meshes with a spiral gear 5i' secured upon one end of a shaft 58 extending` horizontally in relation to the several mafhines, said shaft beine provided within each of the machines with spiral gears and which mesh with spiral ,gears (it) and 6l carried upon the shafts of the roller 4() and 4-1.

ln order to maintain the laundry upon the apron during the automatic feed ing; of

Lit

the Work to the ironer conveyor as said apron traverses between the

guide rollers

18 and 17, an endless apron 62 is extended between an upper roller ($3 and a lower roller 64. said upper roller having its shaft ends 65 slidably engaged in inclined slots (3G in the side frames so that said roller frictionally bears against the roller 18 and is driven thereby. The aprons between said rollers 1S and 17 are tensioned by means of a roller 67 engaged at the inner side of the apron (r2 and having its shaft ends GS slidably supported in horizontal slots (it) in the sidey frames, and in which slots said shaft is adapted to be adjusted to regulate the tension on said aprons.

At the forward side of the machine, and disposed above the traverse of the apron 10 extending between the rollers 18 and 19, there is provided an adjustable loading and feeding apron extended at its outer end about a relatively large diameter roller 7l having its shaft ends 72 journaled in the side frames 1() and extended at its inner end about a relatively smal] roller 7? disposed directly above the roller 151. said

rollers

72 and 73 being connected together by tapered side plates 74, pivotally mounted at their outer ends upon the shaft 72, and rotatably supporting the roller 73 at their inner ends. rl"he apron 70 is preferably in the form of a plurality of parallel tapes and adjacent and above the roller 73 is engaged by a gravity friction roller 75, having its shaft ends 70 engaged for vertical movement in vertically slotted ears 77 formed upon the side plate 74 and serving to retain the laundry pieces in flatwise relation upon the apron 70 as the same are engaged and fed by the apron 1G into relation about the upper roller 20. The apron 70 is tensioned by means of a roller 78 supported at its ends by lever arms 79 pivotally mounted at 80 upon the side plate 74, said roller having its shaft ends 81 engaged in slotted portions S2 of the side plates whereby the weight of the roller bears downw^.rdly upon the lower traverse of the apron. The driving mechanism for the apron 1G and the apron 70. and which will be presently more fully described, is such that the apron 70 is operated at a slightly slower speed than the apron 1G. providing a retarding tension upon the laundry pieces as they are fed from the apron 70 to the apron 16, which in cooperation with the friction weight roller 75 provides a retarding tension upon the laundry pieces, causing them to stretch slightly as they are fed upon the apron 1G and which insures their disposition in the apron being rolled about the upper roller in a smooth flat relation.

The several machines are adapted to be driven from a single source and for this purpose an electric motor 83 is provided, which through a flexible coupling S4 drives a horizontal shaft 85 extending to the several machines at one side, and provided in relation to each of said machines with a worm drive 80 disposed within a supporting housing 87. and meshing with a worm gear 8S, provided upon its shaft 89 with a sprocket gear connected by a sprocket chain 01 to a sprocket gear'fl'l mounted upon the shaft 72, and adapted to be connected by means of a sliding clutch 9?) to a sprocket gear 94 also mounted upon said shaft 7;). The clutch 93 adapted to be shifted by means of a `bell-crank lever 05, having a forked upper end 00 engaging the clutch and connected at its lower end by a link 0T to a 'toot lever 0S pivotally mounted upon the side frame at 00, this lever being in such relation with respect to the platform 2o, that the operattn' standing thereon may engptgc and disengage thc clutch at will, so that as the foot lever is depressed the machine will operate. and will stop when the lever is raised, it being understood that the machine will be operated in this intermittent manner to permit the operators to selectively arrange the laundry pieces upon the apron 70, aml thereupon cause them to he fed to the apron 16.

The sprocket gear SH is connected by a sprocket chain to a sprocket gear 101 mounted upon the shaft 102 of the apron roller 1). and adapted to be connected to said shaft by means o1 a clutch 10?) disposed upon the shaft r102 at one side of the machine, and adapted to be operated from the other side of the machine by means of an elongated pullod 101 extending through

guide brackets

105 and 106 supported upon the side frames, and connected at its end to a hand lever 107 pivotally supported at 10b upon the bracket. 10o. The projecting end of the shaft 10; is journaled in the hearing bracket 10i). and at the inner side of said bracket there is secured upon said shaft a sprocket gear 110 connected by a sprocket chain 111 to a sprocket gear 112 secured upon the shaft 11? of the roller 18, and through which said roller 1S is adapted to be driven in synchronism with the roller 19.

As the roller 71 is of slightly smaller diameter than the roller l) the speed of travel of the feeding apron 70 is slightly less than that of the apron 1G, the sprocket wheels 9-1 and 101 being ot' equal diameter. During the normal loading operation ot' the machine. the clutch 10?, is connected and the wlmle machine intermittently controlled b) operation of the clutch 0?) through the foot iever 9S. During the feeding operation to the ironer both clutches 93 and 103 are disc-.nmected, the clutch 10?, disconnecting the

rolls

16 and 10 from the gearing, so that they are free to rotate.

During the loading operation the apron 70 and its supportingframe are adapted to ltr() be moved into substantial engaging relation with the roller 19, as shown in full lines in the right hand machine, F ig. 4, while in the feeding operation to the ironer it is adapted to be raised with respect to said roller as shown in full lines in Fig. 1 and in the left hand machine, Fig. 4. For the purpose ot cllecting this raising and lowering movement, a hand lever 114 is secured at one end to a rock-shaft 115 extending transversely across the machine and rotatably supported its ends in standards 105 mounted upon the upper side olf the side frames 10, and adjacent each oi said standards, lever arms 11T are provided upon the shaft. 115. these arins rotatably supporting between their inwardlyv projecting ends a transverse bar 11d. and beine( pivotally connected at their outwardly projecting ends 119 by links 12'.) io the side 'trames 'T4 ot the apron TO. The lever arm 114 is adapted to be moved between two pordtions ol' adjustment, and to be fixed at such positions by means o1' a detent 121 adapted to engage

notches

122 and 123 in an arcuate guide support 124 mounted upon the side traine 1t) at one side of the machine. lily mowing the lever arm 114` between its :wo positions it will be seen that the apron is moved into and out otl relation with thtI roller 19.

Upon the bar 118 there are secured a series oiE supporting arms 125, eonneeted at their inner inojecting ends to a doffer or scraper bar 126 extending transversely across the machine, and adapted during the feeding operation to the ironer to engage the surface Aof the apron 16 rolled upon the upper roller 2O for the purpose of insuring the removal of the laundry pieces therefrom and also adapted, as will presently more fully appear. to operate a automatic switch mechanism for adjusting the position of the roller 2t) during such feeding operation. .it each end ot the bar 118 there are secured up vardly extending arms 12T connected by springs 12S to suitable eyelets 120 secured upon the upper ends ot the standards 116, and adapted to press the (loller plate yieldably into engagement with the apron 16 as shown in Fig'. l.

lnringl' the feed ing operation to the ironcr the apron 1G is rolled from the upper roller upon the lower roller 15, and at. the benning ol' such operation the. upper roller is moved to its uppermost position upon the tracks 23 in spared relation to the roller 19, while the lower roller is lowered into friclional engagement with the rollers 40 and 4l ot' the ironer conveyor 28. 1n order to raise the roller 20 to such position, its supporting trucks 22 are respectively connected at their upper ends to cables 130. extending over guide rollers 131. 131 rotatably7 supported in the upper ends of the bracket portions 25, and connected at their ends to a winding shaft 182 supported at its ends in suitable brackets 133, and provided at one end with a hand wheel 134 by means of which said shaft may be first turned to take up theI slack Vin the cable caused during the loading operation as the apron rolled about. the upper roller 2() has been increased in diameter, and t'urther turned to raise said roller into spaced relation to the roller 19 through further winding of the cable on said shaft. he shaft 132 is thereupon alapted to be secured in such position by means ot a clutch 135 which upon being shi itc-:l connects it to a worm gear 13G, meshing with a worm 13T mounted in a suitable bearing housing 1518, and adapted to be driven through a coupling 139 by an electric motor 140 supported upon a bracket 141 sccured to the side frame 10 at one side. This motor is normally inoperative and the meshing relation o1` the worm 137 with the gear lil is such as to lock the latter, so that when the clutch 135 is engaged the cable winding shaftt 132 held against rotation. The clutch 135 adapted to be shifted by means ot a forked lever 142 connected by a pull rod 143 to a hand lever 144 disposed in accessible relation adjacent the hand wheel 1254.

As the machine is operated to feed the laundry pieces to the ironer conveyor the upper roll and apron gradually decreases in diameter and the lower roll and apron increases in diameter and in order to maintain a substantially constant spaced relation be ineen the surface of the apron upon thc upper roller and the roller 19 and to maintain substantially the same relation to the dotfer bar 126 so that the laundry pieces may be disturbed as little as possible should they stick to the upper roll and have to be removed therel'rom by the doffer bar, the upper roller is adapted as it decreases in diameter to a predetermined extent to be lowered sntliciently to compensate for this decrease tl'irough operation ot' the motor 140, which through the worm 13T and gear 136 reels ofi' the cable 13() and lowers the roller 2t) to such desired position. For the purpose of automatically controlling this action, a rod 145 is secured in depending relation upon the rod 118 and is disposed at its lower end between spaced stop lingers 141i and 147, provided upon a pull rod 145%. pivotally secure(L at one end to a svvitch lever 149, connected to a toggle switch 150 secured upon the arm 11T at one side, this switch being connected by suitable lead wires 151 to the lead end control switch 152 of the motor 140, said switch 132 being mounted upon the bracket 141.

Referring particularly to Fig. 1, the operation of the switch mechanism is as follows As the diameter of the rolled apron upon tit) the upper roller decreases in size, theI doit'er bar 12T follows Vits surface, through the action of the spring 12a. gradually rotatingr the bar 11S in clockwise direction, movingr the rod 1-l5 gradually into engagement with the stop 11G upon the rod 11S. and as this movement continues shitts the rod 14S to the right to a point where the switch lever 149 is thrown into circuit closing relation with a snap action. causing the motor 14() to be started up.y whereupon the trucks 2:2 are lowered upon the tracks Q3 through gravity. Dui-ingr this lowering movement. the dotfer bar 12T is swung downwardly. rotating the bar 11S in countera/Leltwise direction and causing the rod 145 to engage the stop 14T of the rod 14S, and at a proletermined point to throw the swit-rh in the opposite direction to open the circuit and thereby stop the operation ot the motor. This operation repeated at intervals throughout the feeding' of the laundry to the ironer and inaintains a substantially constant spaced relation at the point ot emergence of the laundry pieces from the upper roller.

Duringr the loadingy operation the upper roller is lowered into engagement with the roller 19 through disconnecting;Vv the clutch 135 and reeling oliA the cable 1232() through operation of the hand wheel 131. while the lower roller 15 is raised in spaced relation with respect to rthe ironer conveyor. For this purpose the supporting slides 12 are respectively connected at their upper ends to cables 155 wound about and connected at their upper ends to a winding shatt- 15G journaled at its ends in the upper portions otl the side frames 1t). and provided at one end with a hand wheel 15T adapted through rotation to wind the cable upon .said shaft to lift the lower roll to th:` dotted line position as shown in Fig. Q. the same bein;r held in such position by suitablel pawl and ratchet mechanism 15S.
