18 Claims. This inventionreiates to laundry presses and {I particularly to laundry presses wherein portions ofthe work piece or garment which hang from the pressing surface of the work-supporting element are supported in a manner to prevent soiling 'or wrinkling of the. overhanging portions while the portion of the garment on the support is pressed by an upper heated member.
More specifically the invention relates to a laundry press comprising a frame, a heated pressplurality of garment supports hereafter called bucks, means to, move said bucks pivotally from ,a pressing position to a work-receiving position,
and means to apply pressure between the head and the particular buck positioned in pressing relationship thereto, the arrangement being such thatwhile the garment on-the loaded buck under the head is being pressed the second buck is in Work-receiving position.
The invention maybe further summarized as consisting of the construction and combination of parts facilitating the movement of successive bucks into a pressing position whereby the plurality of bucks can'be pivotally moved between a a heated ironing headQthe loading positions of the said bucks being substantially the same and being suitably positioned with respect to the norbuck tothe other.
r The invention further consists in an arrangement of parts facilitating the movement'of the bucks above and beneath each other from a composition.
The invention further consists in novelv control arrangements of the movements of the elements mentioned for the purposes set forth;

l and 2 resting her 4 held in place by bolts Sand 6. The midportion of the cross tie 4 carries a cylinder 1 with upper and lower caps 8 and 9 respectively. Within the cylinder 1 is a piston l0 attached to a rod .ll extending through a coiled spring l2 and through the cylinder lower cap 9 to a steam heated head l3 having a steam connection not shown and a lower work surface H. The cylinder upper cap 8 .is provided with a fluid connection l5 through which fiuid is supplied to actuate-the piston [0 against the spring [2 so as to carry the pressinghead l3 downwardly sufficiently to bring the work surface l4 into pressing engagement with garments supported in a manner now to be described. I 4
Extending crosswise of the frame, adjacent the base plate 3 and mounted in the end frames l and 2 there is ashaft [6 which preferably intersects the extension of the axis of cylinder 1. Adjacent the end plates l and 2 upstanding arms I! and I8 operatively connected to shaft l6 support a table IS on which is mounted a buck 20 having .anupper work supporting surface 2|. In service this work supporting surface 2| may be provided with a pador other elements not shown. The cooperatingsurfaces Id of the heated head I3 and 2| .of the buck 20 shown for example in Fig. l.
Adjacent the inner sides of upstanding arms I! and I8 are double bearing standards 22 and 23 mounted on the base plate 3. The lower bearings of the standards 22 and 23 support the shaft .16 andtheir upper bearings support a parallel shaft 24. Adjacent the inner side of one standard 22 a. pair ofquadrant gears 25 and 26 are attached to the shafts. I6 and 24 respectively. These gear connections cause the shafts l6 and 24 to .rotate in opposite directions when either of .them is actuated. Similar gears, 21v and 28 may be provided adjacent the other standard.
' Upstanding from the upper quadrant gears, 26 and 28 are cylinders 29 and 29 respectively. Within the. cylinders 29 and 29' are pistons'attached to piston rods 3| which support the ends of a table 32. On the table 32 is mounted a buck 33 having a work piece supporting surface 34. The curvature of the work supporting surface 34 is the same as that of the previously mentioned Work supportingsurface 2| ofbuck 20 and is are curved to internest, as r adapted to intermittently cooperate with the work pressing surface M of the heated head I3. Padding or other covering not shown may be provided on the member 34. Attached to the end frames and 2 are cylinders pivotally mounted as at 35 to the frames. In each cylinder there is a piston attached to one end of a piston rod 38 extending through the free end of the cylinder 36 and terminating in a yoke 39 pivoted on pin 40 on the upright I! or l8, on the forward side thereof. To eyes 4| on the rear sides of the uprights H and I8 are attached extension springs 42, the other ends of which are held to the respective end frames by eyes 43. The springs 42 normally hold the arms I1 and I8 inclined to the rearward so that the members M and 2| are 'in cooperative alignment.
The pivotally mounted cylinders 2929' which support the buck 33 are preferably so designed as to permit movement of the buck 33 between a work-receiving position such as is shown in Fig. 1 wherein the piston rods 3| are extended, and a position such as is shown in Fig. 3 wherein the piston rods are retracted so that the buck 33 may pass freely beneath the buck 20 as these two,
work-receiving elements are swung between pressing and work-receiving positions. It will be understood that the work-receiving position of the buck 33 is shown in Fig. 1 as one wherein the piston rods 3| are extended substantially to the same extent as the rods are extended when the buck 39 is in pressing position, as shown in Fig. 4.
To effect the various positionings of the elements thus far described, a source of fluid pressure and means to control its operation at various times and locations will now be described.
Referring particularly to Fig. 1, a fluid supply line 50 as shown with a valve 5| which extends right and left branches 52 and 53 respectively with supply lines 54, 55, 51 and 56 to the pressure control valve 53, buck reciprocating control valve 59, buck swinging control valve 69, and main control valve 6|, respectively. The three way control valves- .58, 59, 69 and 6| have operating levers 62, 6.3, '64, 65 respectively, exhaust lines 66, 61, 68, 69 respectively, and operating lines I5, 10, H and 12, respectively.
The head control valve 58 is held on the frame by bracket 13 so that the valve operating lever 62 is in operative contact with a piston rod 14 on piston 15 in cylinder 16, held in position on a bracket TI attached to the frame. The piston is held in the retracted position by a spring 18 and in the advanced position by fluid pressure,
from line 12 controlled by valve 6|. The lower end of the valve lever 62 carries a pivoted extension 19 adapted to swing freely to the right as shown and to act as a lever extension and. to
cause lever movement to the left when pressure thereon is exerted from the right. The said pressure from the right may be exerted by the tip of a lever 89 pivoted on the frame by pin 8|, the lever being normally held to the right of the position shown in Fig. 1 by the spring 82' hearing the mounting in cylinder 16 serve to retract the rod 83. Under certain operating conditions later to be described, by detaching the flexible tube 19 from cylinder 29 and adjusting the tube to the inlet 85, fluid is supplied for the cylinder 84.
A piston and spring (not shown) mounted in cylinder 84 similar to When the valve lever 62 is swing to the right and the lever 8|! is then actuated to the right the lever extension 19 swings sufficiently to permit the lever to pass therebeyond after which the lever extension 19 drops back into position to receive the thrust from the right previously described.
Referring to control valve 59, supported on bracket 86 on the frame, the lower end of the valve lever 63 carries a pivoted extension 81 adapted to swing freely to the right, as illustrated, and to act as a lever extension and to cause lever movement to the left when pressure thereon is exerted from the right. The said pressure from the right is exerted by the tip of .a lever 89 mounted on the cylinder 29 as the said tip swings in its arc of travel. The said arc of travel carries the said tip beyond contact with the hinged member 81 and on its reversed movement pressure of the said tip swings the lever extension 81, without moving the valve arm, sufliciently to permit the passage of the tip, after which the extension 81 drops back into pressure receiving position.
The valve operating arm 63 of valve 59 is actuated to the right by a rod 96 mounted (with a piston'and spring not shown) in cylinder 9| held by bracket 92 to the frame. The cylinder 9| is supplied by motive fluid from operating pipe 12 controlled by valve 6| and lever 65. The exhaust line 61 from the valve 59 supplies motive fluid to a force plunger 93 (see Fig. 5) in cylinders 94 projecting angularly from the upper ends of cylinders 29-29. The plunger 93 bears against a lever 95 recessed .into the piston rod 3| and hung on pin 96. A spring 9'! bearing on the piston recess wall and on the lever 95 tends to force the latter outwardly against the plunger 93 when the piston rod is at the upperlimit of its travel and against the inner wall of the cylinder when the piston rod is below said limit. At the upper end of the cylinder a recess is provided in registry with the recess in the piston rod and with the cylinder 94 in which is housed the plunger 93. The base of the recess provides a shoulder 98 against which the lever 95 is swung by spring 91 when the upper limit of travel is reached. With the lever 95 resting on shoulder 98, the piston rod 3| is locked against downward movement, while the plunger 93 contacting the lever 95 is positioned to release the lock when actuated by motive fluid supplied by line 61 to cylinder 94.
,An exhaust passage 99 from cylinder 94 is provided for the motive fluid which is released thereto by the travel of the plunger 93 in its releasing operation on lever 95.
Referring to the main control valve (shown in detail in Fig. 6 from an extension 65' of lever 65), an extension spring I99 is hung and anchored to the-frame. Normally the extension 65' bears upon a plate ||l| on the upper end of a piston rod I02 carrying a piston I93 housed in a closed cylinder I04 mounted on the frame. Within the cylinder and normally below the piston is a supply of liquid I94 against which the piston bears in consequence of the pull transmitted from the spring I00. The piston has a small passage I05 thru which the liquid gradually passes into the upper part of the cylinder as the piston under spring pressure gradually descends. This combination acts as a dash pot to co-act with valve 6|. The piston is supplied with a Valve not shown which accommodates the quick return of the piston to the upper end of the cylinder. The piston rod I92 projects downwardly through the closed cylinder to contact the free end of a valve arm I06 of a valve I01 in the motive fluid supply line to valve 60. The anchored end of valve arm I06 is held by a spring I08 anchored-to the frame. The spring I08 is relatively weaker than spring I00. The force of spring I08 and the resistance of the piston against the liquid I04" are coupled against the relatively heavier spring "I with the valve I01 open. Inactivity or lack of manual manipulation of lever 65-65' by the operator over a period of time will allow the spring I00 to exert its full measure of operativeness to close the valve I01 and so cut off motive fluid from the buck swinging control valve and cylinder 36 to prevent any scorching of material between the head and buck members.
A bell crank I09 hung on the frame on a pin IIO has laterally extending arms III and H2. The forward arm III is positioned under the valve operating arm 64 of valve 60 controlling swinging movement of the bucks. The arm III may be shortened by removing bolts III resulting in the operativeness of bell crank I09 under certain conditions later mentioned. The rod 3| in its downward movement previously mentioned carries table 32 downwardly into contact with valve arm 64 to open the valve 60 and swing the bell crank I09, lowering arm III and raising arm 'I I2. Arm H2 is thus positioned to receive the downward thrust of table 32 when it retreats from the pressing position in cooperation with head I4 in a manner later to be described.
Assuming that the mechanism is in the position shown in Fig. 1, that a garment has been pressed on buck 20 and that a garment is positioned on buck 33 for pressing, the operator then manually depresses lever 65 on motive fluid valve 6|. Motive fluid is thus released to cylinders I6 I and 9|. The piston rod 90 associated with cylinder 9| and valve 59 swings the valve arm 63 to release motive fluid from cylinders 2929 through line I0 to line 61 and thence to plunger 93 which results in the release of stop lever 95 from its seat 98 so that the rod 3! descends with table 32 and buck 33. Meanwhile the motive fluid in line I2 supplied to cylinder I6 actuates rod I4 which swings valve arm 62 to release motive fluid from cylinder I through line I5. The operation of the two-way valves 59 and 58 is practically instantaneous with the depression of valve hand lever 65 and upon the release of the latter its return to the exhaust position for cylinders I5 and 9I is assured by action of spring I 00. The exhaust of motive fluid from cylinders I6 and 9| results in return of the rods I4 and 90 to their retreated positions ready for action again upon their respective valves. With the release of motive fluid from cylinder I, spring I2 raises pressing head I3 from contact with buck 20 a distance suflicient to accommodate lateral movement of the buck 20. The further descent of table 32 makes contact with the valve arm 64 and depresses the bell crank arm III, raises the arm H2, and admits motive fluid to the buck swinging cylinder 36.
The pull generated in the cylinder 36 and imparted to the rod 38, shackle 39, uprights I1 and I8 through shaft I6 and segment gears 21 and 28 and cylinders 29-29 swings the bucks 20 and 2I into exchanged positions. As the cylinders 29-29 move backward the member 39 contacts the hinged valve lever extension 81 at a time such that the resultant operation of the valve 59, the admission of motive fluid into cylinders 29 29 and the raising of table 32 act toclear lateral bell crank arm 2 of contact with the table 32. The continued elevation of the table 32 brings the latter in contact with the hinged lever causing the latter to exert pressure from the right against the hinged valve arm extension I9, thus operating the valve 58 which admits motive fluid to line I5 and cylinder I and forces downward the piston I0 and the attached heated head I3 against the buck 33, which is now rigidly held upward .by the action of the lever 95 just seated on the shoulder 98 as before described. While the two pressing members are in engagement a garment isfplaced in position upon the forward buck 20, and then the valve lever 65 is depressed to admit motive fluid from line 56 to line I2.. Again as before described, the piston rods I4 and operate valves 58 and 59 respectively to their exhaust positions permitting the spring I2 again to raise head I3 and exhausting motive fluid from cylinder 29 to operate plunger 93 and so release piston rod 3I for downward movement with table 32. The descent of table 32 against bell crank extension II2 operates the bell crank I09 to swing bell crank arm III against valve arm 64 to an exhaust position which allows the motive fluid to escape through line 68. Then the spring 42 draws the arms II- I8 rearward and, through the quarter gear connections, moves the cylinders 29-49 forward. As the uprights II-I8 move rearward the arms 88 contact the hinged valve lever extension 81 to exert pressure from the right and position the valve 59 for admission of motive fluid from supply line 55 to line I0 and thence to cylinders 29-29 forcing the members 3| upward until the swinging lever looks at the upper limit of travel to hold the buck 33 in the upper loading position. As the upright I8 swings to the rearward in consequence of pull by spring 42, the table I9 contacts the lever 80 resulting in pressure by the latter from the right against the hinged valve arm extension I9 sufficient to set the valve 58 to admit motive fluid into line I5 and cylinder I and so move head I3 against the garment on buck 20. This completes a full cycle of operations by the mechanism.
It is to be noted that the motive fluid lines to the swinging cylinders have the flexibility required to accommodate the movement of such swinging members. In some cases the vertical movement of the buck 33 may be dispensed with. When thismethod of operation is desired the motive supply line I0 is detached from cylinder 2929 and attached to connection 85 of cylinder 84 and the bell crank extension III is removed by removing bolts III which unbalances the bell crank I09 which then settles to rest against bracket 86 on theframe. In, this case the automatic operation of the valve arm 64 is replaced by a manually operated lever 64 shown in dotted outline in Fig. 1 connected to the valve 60 in such amanner as to attain the action required from the position shown. When the arm 64 is used, arm 64 is removed so as not to be interfered with by contact with table 32.
Again considering the mechanism as shown in Fig. 1, with the modifications outlined in the above paragraph, the buck-33 is to be considered as lowered and table 32 in close proximity to cylinders 29-29. With a garment placed on buck 33 in its lowered position the lever 64 is then elevated, after depressing the lever 65, thus admitting motive fluid to the respective valve controller cylinders. The elevation of arm 64,
operating valve 69, admits motive fluid to cylinder 35 which swings buck 33 rearward and buck 28 forward, after the depression of lever 65 admits motive fluid to valve 58, releasing head 13 from buck 29 to allow it to pass. Also depressed lever 85 has operated to shift valve 59 to an exhaust position. As the swinging bucks assume reversed positions, the arms 89 on the cylinders 2929' contact the hinged valve arm extension 8'! and exert pressure from the right sufiicient to operate the valve 59 admitting motive fluid from line .55 through repositioned line 18 and connection 85 to cylinder 84 thereby actuating piston rod 83 against lever extension 89. The lever 80-88 exerts pressure from the right against hinged valve arm extension 19 opening the valve 58 thereby admitting motive fluid to cylinder [2 suificient to bring head l3 all the day down to the buck 33 in proximity to cylinders 2929' for the pressing operation. The operation of rod 83 on lever 89' substitutes for the contact of table 32 in the previously described cycle. With the release of the manual operation of the valve arm 65 the arm is rotated by the spring I99 so that the valve exhausts the motive fluid from cylinders '55, 84 and 9| in which rods 14, 83 and 98 respectively are promptly retracted. With the pressing action on buck 33 completed, first the valve lever 65 and then the auxiliary valve lever 84' are depressed. When the lever 65 is depressed, valves 58 and 59 are moved to exhaust position and head I3 is elevated from buck 33. With the head l3 elevated, the lever 64 is then lowered exhausting the cylinder 38 through line H, whereupon the spring 42 swings the uprights I 'll8 to the rear and cylinders 2929' forwardly. The exhaust thru valve 59 has emptied cylinder 84 by lines and 61 and exit 99. Since the spring 91 and lever 95 are in lowered position the inclined plunger in cylinder 94 occupies a position giving free passage to and from line 91 through exit 99. As the upright ll-| 8 swings to extreme rearward position arm 88 exerts pressure from the right against the hinged valve arm extension 8'! to operate the valve 59 to supply motive fluid to cylinder 84 and so actuate lever 8989'. In this case there are two forces acting on the lever 89-88, the one just outlined and the previously described contact of table l9, both of which effect the downward movement of the head l3 at the suitable time position.
Now referring to the mechanism positioned as in Fig. 1, after a suitable period of inoperation the mechanism shown in detail in Fig. 6, becomes operative as previously described so that the valve it? is closed and motive fluid through valve 9! is admitted to cylinders 9| and and retained there until the operator manipulates the valve 6!. This tends to hold valves 58 and 59 continuously in exhaust positions until the operator actuates valve 6|.
The opening of the exhaust valves 58 and 59 due to inactivity of operator will occur when the bucks are stationary in either of the positions illustrated in Fig. l and Fig. 4.
With the valves 58 and 59 in their exhaust positions, the effect is for valve 59 to release motive fluid so that head [3 rises from its cooperating buck whether it may be 28 or 33, and for valve 59 to release motive fluid to the plunger 93 so that the buck 33 settles to its lowermost oint of travel. With the bucks and connections in the position as shown in Fig. 1, suppose the safety feature becomes active to shut off valve 181 and exhaust valves 58 and 59. Valve 58 releases head I3. Valve 59 releases lever 95 from seat 98 shown in Fig. 5 resulting in the lowering of the buck 33 and table 32 which would ordinarily operate valve 58 to supply motive fluid to the cylinder 36, resulting in an undesirable movement of the bucks to positions shown in Fig. 4, but the provision of valve I01 which has cut oil the motive fluid prevents the movement of the bucks. So all movement remains absent until valve 6! is manipulated.
With the positions of the bucks as shown in Fig. 4 and the valves 58 and 59 open, the steam head I3 is released to an elevated position, buck 33 and table 32 "are released to a-downward position and table 32 contacts member H2 on bell crank I99 which swings member III against valve lever 64 to exhaust cylinder 36. When cylinder 36 is exhausted the spring 42 pulls the bucks back to positions shown in Fig. 1, the table l9 opens valve 58 by pressure on lever 89 and the head I3 is moved against buck 20, after which all motion ceases. The head l3 remains momentarily in contact with buck 29 until the arm 89 swings past the valve arm extension 19 whereupon the air held in cylinder 18 again releases the valve 58 and head I3 is moved upward for safety.
Referring to the supports for the bucks and their tables, it is to be noted that the bucks with their supports respectively constitute inverted, U-shaped yokes having pivots on shafts I8 and 24, positioned to swing one within the other, the inner yoke having extensible and retractable arms, linkages being provided to secure simultaneous swinging of the yokes in opposite directions. The displacement by the buck on the innor yoke to secure the exchange of positions of he bucks between identical forward and rear positions is in a radical direction along the supporting arms of the yoke.
Other variations in the operations of the principal elements by changes in the control locations and connections are contemplated and such as fal1 within the scope of the following claims are a part of the invention.
