Thisinventionrelatestoa multiple buck laundry press.

Thisapplication is a division of my co-pending application Serial No. 483,230, filed 'Aprilll 1943, nowatent 1\To.`2,i71, i33,` entitled LaundiyMachine."

Presently available domestic laundry presses are oftenlacking in .fiexibility, i. e. they are incapable of'readily ironing orpressing. all types of wearing-appareLlas wellas flat work. The reason for.. this arises usually from the fact that such presses.. have but.. a single non-interchangeable bnck,.suitable for only certain types of work, and whichcannot readily be used for all types of` work. Furthermore, 4inthe useof such a press,V the, oper.- ator. thereof must sitidly; by while vthe press is operating, and. accordingly her time during pressing operations is wasted; also, the press is idle while the` buckis beingunloadediand reloaded.

My laundrypress comprises a double buck arrangementofsuchflexibility asto be readily able totoperate on.. practically all` types, of, ordinary wearingapparel andfflat` Work, the buck arrange.- mentbeing'such .that while one, garment or piece of ilat work. is being pressedanother, of a different.shapemayvbe loaded on thesecondvbuck. Furthermore, the.. machine occupiesbut a. small amount4 of spacein the-laundry or kitchen,.and requires but asmall amount. of.V power. to operate eiiiciently.

While Various types of, double buck `commercial presseshavebeen proposed and even used commercially` with f a, certain amount, of success. such pressesarenot. suitabley for domesticuse, being too bulky, expensive. and diicult to` use andnot having, the, necessary. exibility necessary in a domestic. press Furthermorait is usually dimcult, if notimpossible,` to, operate these. commercial'machines froma= single station, to` say nothingof a seatedposition.

Itisamong the` objects of my invention to provide aflaundrymachine of theabove nature which is simple, inexpensive `and sturdy` in. construction, and Whichiscapable of carryingoutsubstantially allof the laundry pressing operations with aminimum amount of trouble,A and at the same time `Witlra high .degree of eiciency.

Other, objects .willbein part, apparent, and. in part pointed outV hereinafter.

The invention accordingly consists in the features of construction, combination of elements andrai-rangement of. parts, all as Vwill be exemplied in. the structure. hereinafter described, and the-scope of. the application ofl which will,` be in dicatedlnthe following claims.

Thus,4 whileone buck is beneaththe head,` the `other may be'unl'oadedand reloaded..

IirarneA 22 of the machine base has secured thereto` amotor 30T (Figure 3.). the armaturefshaft 31' of whichr is. connected toa transmission. or gear. box generallyA indicated at 32. The output side ofgearboxis` connected asby ashaft 33 to acam, .the center. of which isaligned; with the axisof ayertical` plunger or,- post, slidablgr, dis.- posedfina suitable bearing 36 (Figure :3). carried byframezz. The bottom of-plunger rotatably carriesaoller 36.whiehLrides on cam'.ldtwhile to the top, of.` this, plunger. isefasteneda .platen 31T which, when-the plunger is infitstlowermostzposi? tion, as shown in this gure, resta-.within `ensuit,-Y

able recess formed in table 24. As shown in Figure 2, plunger plate 31 is disposed centrally beneath the bifurcated top of arm 29 and accordingly is centrally located with respect to the center of mass of buck 25, for example, when this buck is in its operating position as shown in Figure 1 It will now appear that when motor 30 is energized it drives cam 34 through gear box 32 and causes plunger 35 (Figure 3) to rise and fall. Thus as the high spot of cam 34 is driven beneath plunger roller 36, buck 25 is forced upwardly with substantial pressure so as to be forced yagainst head 21, properly to press any article of clothing disposed between the buck and head. By a control system to be described hereinafter, buck 25 is maintained in its uppermost or pressing position for as long a period of time as desired and is thereafter lowered to the position shown in Figure 1 to permit its replacement beneath head 21 by the other buck 26.

Thus, as shown in Figure 8, motor 38 has one side connected to a source 3S and the other side connected through a solenoid coil 39 to a stationary contact 46 of a switch generally indicated at 4|. The movable contact 42 of switch 4| is connected bya line 43 to one .side of a control switch generally indicated at 44, having a movable contact 45 engageable with a stationary contact 46 connected by leads 41 and 48 through a main switch 49 to source 38. This circuit'controls the upward movement of the buck, as will be described.

Contact 46 is also connected by a lead 50 to a stationary contact of a cam controlled switch generally indicated at 52, having a movable contact 53 on an arm 54. Arm 54 is connected by a line 55 to the arm 56 of another control switch generally indicated at Y51. Switch arm 56 is connected to arm 44a of control switch 44 by a link 58 and also carries a movable contact 59 adapted to engage stationary contact 68 when switch 51 isclosed. Stationary contact 60 is connected to source 38 by way of lines 48 and main switch 45. It will be noted that when control switch 51 is open, control switch 44 is closed, the former switch controlling the downward movement of the buck.

Switch 4| also includes an arm 4|a and this arm, together with arm 54 of switch 52 is controlled, i. e. moved to and from its circuit closing positions in any suitable manner by cam 34. When cam 34 .is in its uppermost position, as shown in Figure v8, switch 4| is open, while switch 52 is closed. When cam 34 has rotated 180 from this position, switch 4| is closed, whereas switch 52 is open. In operation, and assuming that plunger 35 and cam 34 are in the down position shown in Figure 3 so as to permit the placing of i buck beneath head 21, switch 44 (Figure 8) is closed. Of course, under these circumstances, cam 34 is 180 from the position shown in Figure 8, so that switch 4| is closed. Thus when switch 44 is closed, the following circuit is completed: source 38, motor 30, solenoid coil 39, contacts 4D and 42, line 43, contacts 45 and 46 of switch 44, lines 41 and 48, and main switch 49 to the other side of source 38. Motor is accordingly energized and cam 34 is rotated as hereinbefore described. When the high spot on cam 34 reaches its uppermost position, as shown in Figure 8, contacts and 42 are separated, thus breaking the circuit to motor 36 and accordingly stopping the cam in this position wherein the buck is pressed with maximum pressure against the head.

After the desired pressing period, link 58, which connects the arms of switches 44 and 51, is moved so as to open switch 44 and close switch 51 When switch 51 is closed, the following circuit is completed: source 38, motor 30, solenoid coil 39, contact 48, line 58, contacts 5| and 53 (which engage shortly after the initial movement of cam 34), line 55, contacts 53 and 60 of switch 51, line 48, main switch 49, to the other side of source 38. This circuit reenergizes motor 30 causing cam 34 to rotate until its high spot reaches its lowermost position when contacts 5| and 53 are opened, thus breaking the circuit to motor 30, accordingly restoring the buck to its original position, as shown in Figure 3. Thus it will appear that with main switch 49 (Figure 8) closed, the up and down movement of the buck is accurately controlled by operating the interlocked switches 44 and 51. Thus the operator of the press does not have to watch it closely in an attempt to determine when the buck is all the way up or all the way down.

inasmuch as presses of this character are limited as to power consumption, it is desirable that the heating element in the head 21 (Figure 3) of the buck be deenergized, while motor 33 is operating, and it is to this end that I have provided solenoid 38 (Figure 6). In this gure, I have shown the heating element 6| of the head connected by a line E52 through main switch 49, to one side of source 33, Y The other side of heating element 6| is connected by a line 63 `to a. stationary contact 64 engageable by a movable contact 65, fastened to an arm 56 connected to the solenoid armature 61. Movable contact 65 is connected by a line 68 to the other side of source 3B. Accordingly it will follow that when motor 30 is energized so also is the coil 39 of the solenoid. Upon energization of this coil, armature 61 is drawn to the left, as viewed in Figure 8, separating contacts 64 and 65, thus breaking the circuit of heater element 6|. When, however, motor 36 is deenergized through the opening of either of switches 4| or 52, the solenoid coil 39 is also deenergized and its plunger 61 moves to the right to close contacts 54 and 65, thus energizing heater element 6|. Thus the heating element is deenergized for but a few seconds during the lowering or raising of the buck, and accordingly its temperature is maintained at a substantially constant value. Preferably the heater element circuit includes a thermostat 69 which prevents the elementfrom over or under heating, and a manually operable switch 6 la, by which the heater circuit can be broken when desired.

Under certain circumstances, it may be desirable to decrease the deenergization period of the heater element, and to that end I have provided the alternate circuit shown in Figure 9. In this circuit, element 6| is connected by a line 16 to one side of source 38, the other side of which is connected by a line 1| to a movable switch arm 12, carrying a movable contact 13 adapted to engage a stationary contact 14 connected by a line 15 through thermostat 66 to the other side of element 6|. Switch arm 12 is normally maintained in a central position, wherein contacts 13 and 14 engage, by suitable springs 16 and 11 or the like. Switch arm 12 is pivoted, as at 18, and includes an extending foot 19 which lies in the path of a post fastened to the buck plunger 35. In this view, the plunger is shown in its lowermost position wherein post 80 underlies foot 19. The post and foot are so spaced that they engage just before cam 34 raises plunger V35 to masse its'uppermost'position, i? e: atfthevtimewhen'the buck "iirst enga'ges'tl'ie headi When Ytheliigli `spoton cam'3lreacl1'es3its uppermost position; where` inthe-buck' is exerting maximumpressureon the head and switch 4+ (Figuren) opens, post `8B rides past' footA 19" permitting contacts 13 and 14 to` elose,` thus closingr the circuit Vtzrheater element'll:

As noted-hereinabove, one 'ofthe primary drawbacksto successful domestic`v laundry presses rer sides4 in the` timeV lost between pressing operations. 'Ifo a certain extent this` has. beenovercome in'commercial presses 'throughs the provision offtandem pressesor double buck and head arrangements, but such presses' are' costly;4 bulky, complicated, space-consuming` machines;` and evenv so cannot easilybeoperated from` a single position; i. e; in. most `casesthe operator mustwalk fromstation to station' in orderto unload and"load the inoperative buck while the'other buck is under its'r pressing head: I` have accordingly provided the tablerl 24' shown ini ligures4 I', 2'anjd 3, which comprisesa center section' ll which is preferably notched as at 82'. Seeured to. frame 22`isa suit-V able bifurcated bracket 83 in which the lower end` of armH 2S is pivotally secured as by a pin 8f which extends through. the. arms of bracket 83. A detachable lockingpin 84h` also extends through the armsiofi bracket'83" and through arm 29 tohold the arrnin the'full" line position shown in Figure 3i To the oppositeA sides of' center sectionY al' of table 24 are respectively'hingedleaves 8o,"andfli6,z and on the forward edges` of' these leavesr are hinged respectively drops 8T an'dj88 Center. section 8,1' oi" the table;` leaves 8,5 and 8B; and drops 8T and 88;` preferably have; a channel18j (see also Figure 1)V formed` thz-lfrein, andv centrally of' this channel is' cut a guider slot 9U which. togetherv with the channel, form a, track or guid'eway for bucks 25, and 2H, Preferably each buck is,provided" with a` pair off guide pins 9i (Figure 3) adapted to extend into guide slot, and thebase ofthe. buck is provided with aisuitahle number. of anti-friction rollers 9,2 to facilitatamovement ofV the` buck along; channelBQ. 'Ihe baseofl each. of: the bucks is preferably kidneytshapem as shown at, 93f (Figure- 2 to facilitate; the` travel otf the buck; around` the curved; portions: off charnnel- 89.

As shown in Figure 2; Ii'preferably-'providev a rotatable stool 94-which islocated centrally'lof the machineand between the-loadingstations:A The height of` the stool is such, re1ative-to-the heightV of; the table,- thatthe operator-skneesY may--comfortably-ex-tendbeneath the table or the drops 8lL and 8l3-V and,l illustratively, the edge of the -stool may be threeor fourinehes from the edgeof thetable-andlthe drops.- Thus; theop-` eratorfmay, without moving` fromftheloeation` of' her working position, manually move` buclesA 25 and 26 into and out of-foperation position: beneath the pressinghead.

While I have disclosed and described a gen erally` U-shaped pathovery which the bucks may be moved into and out of" operative position beneath the head,n I` do not desire" to be*4 limited to apath of buck movement or'travel ofrthis precise configuration.- Thus, it will readily'ap pearthat` the buck guiding devices can be ai ranged in various waysA to guide the bucks-be tween theirH loading andL operating stations in such amanner that the operator of the pressY is neither inconveniencednor" forced:v to rise' from her seated position between the loading f stations inorder to move outl of the way ofthe bucks.'

Preferably center portionlioftable Ztltisprovided with a forward portion 8 la preferablyprovided with tracks or othersuitable' guides Sli-'and 96, which facilitate the movementoftheparticue lar buck as, for example, buck 25 which is in op.- erative position under the head, from under the head and toward the operator for rearrangement of the garment on the-buck; unloading of" the buck, and reloadinglor any other operation which the operator wishes tol perform. Thus the machinemay be operated as either a; double or single buck machine, neithermode,necessitating movement ofJ the4 operatorfrom her seatedposiition on stool 94 It will further appear that when two bucks are being used; what might" be termed an lil-movement may be` advantage.- ously resorted to under variousl circumstances'. For example, with bucks 25f and 216 in the solid line `position shown in Figurez; the' operator'may be`` unload-ing; and* then reloading buck. 2li;` while the garment on buck- 25 is beingjpressed., It may be that she wishes to rearrange the garment' on buck 25 prior to removal thereof to' the dotted line position at her left; Accordinglyi the buck may be dropped in the manner. heretofore der-V scribed, and then rolled forward to the d'otted line` position 25f where the` garment thereon is readily accessible tothe operator forreadjistlment or removal.` Thereafter this buck may be rolled baclr beneath the head-and another` pressiing operation is performed. Thus,` when the'gaz-, mentl on buck` 251 is finished; this buck may be dropped and rrranually'moved` to its loadingtsta, tion on drop' 811i. e. to a position beyond= the. dotted linev position of buck 25".Y 'Thereafter'.on indeed at the same time, bucllzllilmay;` barolled into place, beneath the head, whereupon the pressingeycle may be recommended;

By reason of the. provision ofl channel 88gpider slotA 90, guide pins 9,! and rollers: Qz, the bucks; although` of substantial: Weight, to propicie, strength',A may nevertheless bel readily rolled:intr! and out of operativeipositionr withr respect tofbut, ai single pressing head, a's desired. It; willi thus be seen that: there is but` little time lost. between successive `pressing,operations, and: while one-:gan-I ment is being pressed, another may be loaded on the idle buck.

As noted hereinabove, leaves 85 and 85 are hinged to table center section 8|, and drops 81 and 88 are hinged to the leaves. Also, as arm 29 is pivoted to table 24 by the pin 84, the arm` may readily be swung to an inoperative position by withdrawing pin 84a and swinging the arm about its pivot to the dotted line position shown in Figure 3. The top of arm 29 has a handle 29a (Figures 1 and 2) by which the arm may be pushed backward from its full line position in Figure 3 so as to move head 21 away from the top of the buck to enable the operator to rearrange or replace the article on the buck. Arm 29 may be heldin this retracted position by a suitable chain or latch (not shown) which may be disconnected when the arm is moved to its dotted line position. Also, head 21 is preferably removably attached to the top 28 of arm 29 so that if desired the head may be removed or replaced, as the case may be. Thus it will appear that through the provision of the hinged leaves 85 and 86, hinged drops 81 and 88, and the removable arm 29, these several parts ofthe machine may be folded into the dotted line positions shown in Figures 1 and 3, soV that with the parts so folded away the machine takes up but little room and may readily be rolled into a small corner of the laundry or kitchen, wherever the machine is used, and thus be disposed out of the way, or used as a, utility table, if so desired. Suitable pivoted supports 98, 99, and |0| (Figure l) are provided to hold the leaves and drops in their unfolded position when the machine is in use.

As best shown in Figures 2 and 4, each cf the bucks, as for example buck 25, is provided with a notched plate |02, the notch |02a of which receives a spring-biased detent |03 reciprocably mounted in bracket |04 and biased to the right, as viewed in Figure 4, by a spring |05. Bracket |04 is preferably fastened to arm 29 near the bottom thereof (see Figure 3) in such a position as properly to position buck (Figure 2) beneath the pressing head 21. not have to rely on her judgment in properly positioning the buck beneath the head, but merely rolls it into its approximate position so that the detent |03 and the notch in plate |82 may engage.

It will now appear that having placed one of the two bucks, for example buck 25 (Figure 2) in operative position beneath the head, the operator merely closes switch 44 (Figure 8) which may be located on the machine in any suitable and readily accessible position, whereupon the buck is forced upwardly against head 21 (Figure l) into its pressing position, wherein it is automatically maintained for as long a period as desired, while the other buck 26 is being unloaded and reloaded. When the pressing operation is finished, the operator merely closes switch 51 (Figure 8) at the same time opening switch 44, causing the buck to fall to its lowermost position whereupon it may be removed and the other buck rolled beneath the head.

It is desirable periodically, particularly after the bucks have been in operation over an extended period of time to dry, or at least partially dry the pad on the buck. To this end, and as shown in Figure 8, I have provided a bypassing circuit comprising leads |06 and |01 and a switch |08. Lead |01 is connected to one side of source 38 and one side of switch |08, while lead |06 is connected to the other side of switch |08 and to one side of motor 30. Thus when switch |08 is Thus the operator does closed, motor 30 operates continuously, regardless of the position of the buck switches 44 and 51, thus causing the buck beneath the head to rise and fall steadily until switch |08 is opened. This intermittent engagement of the buck pad with the head suitably removes the excess moisture from the buck pad. As noted in Figure 8, switch |08 is mechanically coupled to switches 44 and 51 by a link |09, and to switch 49 by a link |51. Thus when switch |08 is closed, switch 49 is opened, thus breaking the circuit to heater coil 6|.

In Figures 5, 6 and 7, I have shown a modified form of my double buck laundry press. In

. this form I utilize the buck raising and lowering devices, as described hereinabove. In the Figure 5 form, however, I provide a table generally indicated at ||0 on the sides of which are hinged leaves and I |2, which may be folded down for storage purposes, as hereinbefore described with respect to leaves and 86 (Figure 2). As shown in Figures 6 and 7, base frame 22 is provided with a journal ||3 in which is rotatably disposed a post ||4 which may be held in proper operative position by a nut ||5 threaded on the bottom end of the post. The upper end of post |4 has a head I I6 and between this head and the top of journal ||3 are the hubs ||1 and ||8 of a pair of arms generally indicated at ||9 and |20 (Figure 5). These arms are respectively joined to their hubs by goosenecks I2| (Figure 5) and |22 (Figure 7) so that the arms lie in the same horizontal plane. Hub ||1 of arm ||9 is provided with an operating handle |23 (Figure 6) and as shown in Figure '1, the two arms may be coupled together in relationship by a spring-pressed pin |24 extendable through flanges |25 and |26 formed on the hubs of the upper and lower arms, respectively. Thus when pin |24 extends through these flanges, the arms are held 90 apart and accordingly pivot together about the axis of post I4. When pin |24 is withdrawn, however, the arms may be pivoted separately so that either may be used. Otherwise arms ||9 and |20 are identical, and accordingly arm ||9 only will be described in detail hereinafter.

As shown in Figure 5, arm I9 is provided with an elongated slot |21 which extends from a point adjacent the inner end of the arm to a point |28 adjacent a rectangular opening |29 formed on the outer end of the arm. A continuation |28a of slot |21 is provided adjacent the outer end of the arm, this slot and opening |29 being provided for a purpose to be described.

Bucks 25 and 26 are in general similar to those hereinbefore described, but differ in that, for example, buck 25 (Figure 6) is provided with a pair of cups |30 and |3| in which are respectively disposed the upper ends of guide pins |32 and |33 provided with suitable heads between which and the bottom of pan 25a are disposed springs |34 and |35. Pins |32 and |33 extend respectively through slot |21 and slot extension |28a when buck 25 is in operative position, wherein they are held by heads on the lower end of the pins. Thus the buck may move upwardly a limited but sufficient amount, upon upward movement of vertical plunger or post 35, the vertical plunger or post preferably having a table |36 fastened to the upper end thereof which extends through opening |29 upon upward movement of the plunger. When the plunger is moved down to the position shown in Figure 6, springs |34 and |35 force buck 25 downwardly until it again rests on arm ||9.

As shown in Figure 5, the top 28 of presser head supporting arm 29 overlies opening |29 in arm I|9 so that the presser head will overlie the buck when the buck is in operating position,

Arm |20 movably supports buck 26 which is shown in the full line position, i. e. the loading position in Figure 5, It will now appear that when the machine is operated, arms I I9 and |20 are moved to the position shown. Subsequent to the pressing operation on buck 25 and the reloading of buck 26, buck 25 is dropped, as described above, and may thereafter be moved to the dotted line position for the same purposes as described in connection with the press shown in Figure 2. With the bucks in their full line positions (Figure arms I|9 and |20 may be pivoted counterclockwise until buck 25 has moved 90 from the position shown, where it will overlie table leaf I I I. This movement moves buck 26 into position under the presser head, whereupon the pressing and loading cycle may be recommenced.

To facilitate this back and forth movement of arms I I9 and I 29, each of the arms preferably has attached thereto a pair of rollers |38 which roll along the top of table I|0 as the arms are moved, accordingly supporting the arms and bucks. Here again it will appear that the operator seated on stool 99 may remain so seated during the pressing and loading operations without the necessity of moving to completely operate the machine.

As many possible embodiments may be made f of the above invention, and as many changes might be made in the embodiments above set forth, it is to be understood that all matter hereinbefore set forth or `shown in the accompanying drawing is to be interpreted 'as illustrative and not in a limiting sense.
