In Great Britain May 12, 1938 f 23 Claims. (6138-22) This invention relates to presses and more specifically to laundry presses.

In general. it is an object of the invention to provide a device of the character described which will efliciently perform the purposes for which it is intended, which is simple and economical of construction, which can be expeditiously, conveniently and safely manipulated, and which can be readily manufactured and assembled.

Another object of the invention is to provide a press which occupies a minimum of space and. which does not have an excessive number of 'parts, and which also is so constructed that the operator may put the work onto the press at a convenient loading position and preferably at the same or substantially the same loading. positlon for a plurality of bucks and to provide such a. press in which one head and buck may be put through a cycle of any number of operations independently, without any other head and buck being operated or while another head and buck stand in pressing engagement; and to provide such a-press in which the total pressing'force e2- erted is automatically changed in proportion to the number of bucks and heads which are in pressing engagement.

Other objects of obvious and will in part appear hereinafter.

The invention accordingly comprises the fee;-

.tures of construction, combination of elements and arrangement or parts which will be exemplifled in the construction herelnafter'set forth and the scope of the application of which will be indicated in the claims. For a fuller understanding of the nature and objects-of the invention, reference should be had to the following detailed description, taken in connection with the accompanying drawings, in which:

Figure 1 is an end view-of ing one form of the invention;

shown in Figs. 5-7;

Fig. 9 is a front view of another form of the invention: and l Fig. 10 is a diagrammatic representation of the machine shown in Fig. 9.

The present invention contemplates a spacesavlng machine and a time-savinq nachine and one wherein each buck has its loading position positioned conveniently with respect to the hands of the operator. For each buck there is a 1 head with which that buck works. One buck and head may be pressing while another buck and head go through one or more entire cycles of loading and pressing. In this way, all parts. of the machine are constantly intuse and thereby 'pressing of various kinds can becarried on without parts of the machine standing idle. The machine may also be run so that the different bucks are alternately loaded and pressed or they I may be both in loading or both in pressing position. In Figs. 9 and 10, a machine is'shown in which the travel of the. bucks isshorizontal, the

bucks belngat all times at about the height of; the operator's hands. In Figs. -1-8a, the heads are somewhat more spaced from each other, al-

though substantially vertically aligned, and

Figs. 5a, 5b and 5c are diagrams of the operation of certain of the elements shown in Fla. 5:

f Fig-6 is a view in section looking toward one I Figs. 8a and 8 are diagrammatic representatherefore one of the bucks must move down from the work-receiving position to its head. There are practical disadvantages, e. g., loss of speed, 'etc., to lower that buck first and then carry it back to its head.

these flgurea the buck is carried along a slanting path downward and backward and before re ching the end. of that path itwould collide wi th'its head, which is to overlie that buck when the latter reaches its pressing position. Means are provided for avoiding this. Such means operate to remove that head from the path of its descending buck in timed relation automatically.

Similarly, the head is removed from the path of its buck Just before the latter starts on its slanting upward path to the work-receiving position. 1 J

In the drawings, l0 denotesa pair of spaced, vertical frames extending between and supported by which is a pair of bucks-l I and I2 and a. pair of respective pressing heads I and It. The materlal .to be pressed is laid on' one of the. bucks while it is forwardly positioned in work-receiv in: position; It is then moved back into contact with its head and the material pressed between i it andthe head. a l 3 A shaft It extends between and is directly supported by the frame l0. At each end of the shaft In the machine shown in there is a. bell crank having a lower arm 22 and an upper arm 24. Buck II has horizontal trunnions 26 at the ends thereof and these are pivotally carried by, a link 29 which is also pivotally connected to arm 24. A guide block 30 is carried by each trunnion and has a sliding motion restricted to a linear path by the guides 32. The latter extend from the neighborhood of the head I4 forwardly and downwardly toward a point which may be designated the work-receiving position. I

Similarly, trunnions 34 at the ends of the lower buck I 2 are pivoted at the ends of respective links 36, the outer ends of which are pivotally attached to the lower arms 22. Guide blocks 38 on the trunnions 34 are slidable along a linear path which leads downward and backward from the work-receiving position and which is defined by the guides 40 attached to the frame Ill. The guides 32 and 40 are at an angle with each other so as to give intersecting paths for the. guide blocks and bucks. The paths may intersect beyond the points where the blocks stop, at the point where the blocks stop, or the blocks may move across and beyond the point of intersection.

Means are provided to rotate the bell crank 20. These may take the form of a, crank 42 pivotally attached 'to the arm 22 and to piston 44 which is slidable in cylinder 46 into which motivating fluid may be introduced, as described below.

There are means for moving head I6 out of the way of buck l2 as the latter is moved downward from the work-receiving position. As shown, the head I6 may be attached to arm 46 of bell crank 59 which is pivoted on frame I6. A spring 52 attached to the frame I0 and arm 54 of the bell crank 59 tends to hold bell crank 56 so that head I6 is outof the path of buck I2. There are other means for fitting head I6 over buck I2 and for pressing it against that buckafter the latter has been brought down from work-receiving position. These may comprise a crank 56 pivotally attached at one end to an arm 58 of the bell crank 50 and attached at its other end to a piston 66 in cylinder 62. The. arm 58 is so positioned with respect to arm 54 and spring 52 that, when fluid pressure is introduced into cylinder 62, the crank 56 forces bell crank 5M0 rotate, bringing the head I6 down into pressing engagement with buck I2 when the latter is in its lower backward position. I

Figs. 3 and 4 show diagrammatically th fluidoperated means and controls therefor for motivating the various parts described above. A main fluid pressure line 64 is connected to a control valve 66 which has a central element 68 rotatable in a valve casing III. A passageway I2 in element 69 may be positioned to connect line 64 to conduit 14, which leads to cylinder 46 and also to a similar device 16, which, when fluid pressure is introduced into it, causes piston I8 to push head l4 down upon buck l I against the action of springs 80 which normally keep head l4 spaced.

from buck II. The pressure in cylinder 46 causes crank 42 to move out of the cylinder, forcing arm 22 upward until buck I2 is in work-receiving position. Just as arm 22 and arm 24 reach the highest point of their travel, arm 22 contacts valve means 82 in the fluid pressure line leading to cylinder 16. By this means, head I4 is not pushed sure is allowed to pass va1ve'82, it enters cylinder 84, forcing tongue 86 against a lower side of guide block so and prevents the buck II from being pushed out of position by the head I4, as the latter presses against buck II.

While the pressure has been causing the parts .to move as described, a, channel 90 in valve element 68 is connected to valve vent 92 with pressure conduit 94 which leads to cylinder 62 through a pressure control device 96. With no pressure in cylinder 62, spring 52 causes bell crank 56 to rotate so as to lift head I6 out of the path of buck I2 so that the latter may move upward due to the force on arm 22. ,As will be seen later, the motion of head I6 out of the path of buck I2 takes place before the latter begins its upward and forward motion.

When it is desired that the upper buck I I shall be brought to work-receiving position and the lower buck l2 be carried back down to pressing position, valve element 68 is rotated counterclockwise, as shown in Figs. 3 and 4, by any suitable means such as handle 96. Valve element 68 first reaches a position such that passageway I2 no longer connects the main pressure line 64 and line I4, but does connect vent 92 and line I4. This causes loss of pressure in cylinders", 84 and 46 whereby, respectively, head I4 is raised from buck II by springs 80, tongue 86 is withdrawn from' rotation of the bell crank 29 is prevented from being. too rapid by having a pressure control device I94 in the portion of line 14 which leads to cylinder 46. In this way, cylinder 46 acts as a dash-pot.

passageway 69 into a position to connect the main, pressure line 64 and line 94 leading to cylinder A further motion of valve element 68 brings To bring the machine back into the. position shown in Fig. 3, the valve 66 is turned back from the position shown in Fig. 4 to the position shown in Fig. 3. This causes the loss of pressure from cylinder 62, the latter being connected to vent 92. Spring 52 then acts to raise head I6, and pressure is admitted to cylinder 46 whereby the entire process for the turning of the main bell crank 29 is begun again. The pressure control element I04 in line 14 delays the setting-up of pressure in cylinder 46 and, hence, the raising of arm 22 by a,

length of time suificient togpermit spring 52 to raise head I6 out of the patHof arm 22.

The machine shown in Figs. 5-7 is similar to that shown in Figs. 1 and 2 except that arms 22 and 24 are separately rotatable about shaft I6 as an axis and means-are provided for bringing either of the bucks into work-receiving position independently of the other buck. Thus, both bucks may be withdrawn and in pressure relation with their specific heads at the same time. Means are provided for assuring that one buck causes link I20 to latter reaches worke'receiving "f v v, s,s es,ras

is held at its pressure position whenever the machine is operated to bring the other buck to the work-receiving position. ,-As showmthese means comprise a toggle mechanism. There is a uide I06 fixed to. each frame ll. Each guide provides a vertical linear path for a guide block I08 to which is connected a push red I II at the I sh'ai't 4 has been so placed, the pressure in line 44 may be caused to enter line 815 through valve II I. A valve "3 in line 815 is only opened" when a 24 reachesits upper position and contacts lower end of which is a plunger 2 which operates in cylinder 4. Attached to the guide block I08 is a shaft ii! on which pivot toggle M8, the latter extending in opposite directions from the shaft H. A link I20 is pivotally cona, 5b and 50.. In Fig. 5a, the diagram represents the device as shown in Fig. 5 with each buck in pressing position, the upper buck being in upper position and the lower buck bein in lower position. Fig. 5b shows what occurs when'shaft H8, at the center of the toggle H8, is moved up-.

means to be described below. Since arm 24 is -ward from the position shown in Fig. 50, by

raised as far as it can go, the raising oi. shalt H0 pivot around its attachment to arm 24 without the latter. being moved. At the same time as shaft III rises, to gle lit pivots clockwise around the free end oi link I20. The other end or toggle H8 moves upward in an arc clockwise around the free end of link I24. This causes link I22 to be raised upward, forcing arm 22 up-until buck l2 on arm; 221s raised to its upper forward work-receiving position. The reverse action brings buck l2 backto the. positionsh0wn'inFigs.5and&% g

Instead of moving buck II to work-receiving position, it may be desired to leaveit in its low er pressingposition and to bring buck ,ll forward and downward to the work-receiving positifpn. To dothis, shaft ii is movedl downward-by means described below. Inthis case, since'bell an lement of M3, whereupon the pressure in line I'll is transmitted further therealong until it reaches cylinder 18 and, operates the head l4 to compress it against buck ll. Simultaneously, the pressure also passes along to chamber 84 which operates tongue 86 to lock buck II in place, as described in connection with the device shown in Fig. 1,

- Either before or after head l4 has been pressed against buck II but, in .any event, after shait H has been brought to its mid-point, the pressure in line 84 may be admitted to line 8" I through valve Bil whereby the pressure is introduced into cylinder 8 l5, moving the piston there,

' in which, in turn, moves the crank ill! the outer end of which is pivotally attached to an arm 5W which is pivoted at Bil and to which is fixed head it. The head it is normally kept by gravity out of the path-of buck l2. The operation of crank 8H pivots arm his to bring head is in line with the lowered buck is. The pressure in line t"? is also transmitted to a cylinder 822 having a piston 823 which presses against the buck l2 in its lower-position and presses it against its head It. The pressure in line 811 .does not reach cylinders 8|! and 822 until arm 22 hasreached its lower pcsition and contacted an element of valve 88 which shuts off those cylinders from line 411 until so operated. v I

when it is "desired to lower the upper buck l l to work-receiving position, valve 8H is operated so to connect linel'li through a passage 825 to vent I21. This causes the tongue 86 to be retracted and causes head 04 to cease to be pressed against buck ll. Then valve am is manipulated so as to crank arm 22 is as far down. as. it can go, the

end of link :22, which is attached to ,arm.22, remains fixed. As. shaft II is lowered, linki22 rotates clockwise about its point .ol support;on arm 22. Toggle H8 rotates clockwise about the ireelymoving endof link I22 and -iiibolit' shaft Ht. 'I'hiscauses the end of toggleiil, which is attached to Him m, to move. arcu'ately downward, pulling arm 24 and bucki l down until the These Iast-described-means may be reversed by raising shaitfiit until buck H is again cause some of the pressure in line 814 to be lost through vent 828. Thereby, the crank H0 retracts shaft H6, causing link I20 and arm 24 to be pushed downward until head It reaches work-receiving position.

when it is desired to leave buck II in pressing position and to bring buck i2 to work-receivin position, line 8111s vented through valve 8! i.

Thereupon, buck I2 is brought out of pressure.

contact with head I 6 and the latter is swung away dut oithe path of buck i2. Next, valve M8 is operated to permit more pressure to pass through line 814 into cylinder 1 l4 whereby push-rod I I0 position (see Fig.

Each buck is in position to receive its pressing head. I The shaft I hasbeen brought to its mid-position by connecting the main fluid pressure line 84 through valvejll, by suitablemanipulation thereof, to line-814 which leads to cylinder H4. ny controlling the amount oi pressure by means of valve IIO, plunger 2 and att H6 atthemid-point oiitsllvbrtical'motion. with the shaft in that positidn, arm 24' is raised andarm 22, as described above,

raises uide block 188 upward, which motion is transmitted to toggle 8, link i22.and arm 22. The latter; in being raised, carries buck 12 with it upward and forward to work-receiving position-the parts then being as shown in Fig. 8. By

reducing the pressure in H4 and introducing pressure again into line 811, the machine may be brought tothe arrangement shown in il'ig'. 8a.

For-purposes of clarity, the valve arrangements have been shown in Figs. 8a and 8 as though they were in two separate valves.- In practice, these may be combinediin a single valve, so arranged that a single continued motion thereofsuccessiveiy causes the machine to assume is various positions.

In r s and 10 there "isshown another form 'of the jnachine in which the pressing headsmay be simultaneously. pressed against their respective bucksbut which may be so operated that, 1: deaired, a single head presses upon asinglebuck only. The heads are substantially fix d,,l aving but a slight straight up and down motion Just sufficient to allow horizontal motion of the bucks without disturbing the garments which lie on the bucks. The simultaneously movable bucks travel on spaced horizontal ways which lead to forward receiving positions quite in front of the head. The bucks may be moved forward together or backward together, or one may be moved forward while the other is being moved backward, or one may be moved backward and forward as much as desired while the other is kept in pressing position, or while the other is kept in forward position.

In Figs. 9 and 10, 9M denote a pair of frame uprights connected by an overhead element 903.

Each upright carries horizontal guide or track elements 904a and 90% which are vertically spaced from each other. Springs 905 support an upper pressing head 9 I 61) from frame element 903. Lower pressing head 9l6a is connected to the upper head by elements extending from each end of each head to the same end of the other head and comprising, for example, a pair of telescoping tubes 901. 'The latter are intersupported by pins 909. When desired, thepins may be removed, leaving the lower head 9l6a resting on its buck 9l2a. The latter is then out of operation while the upper head 9l6b continues to cooperate with its buck 9l2b, In pressing position, each buck is directly beneath its head.

Pneumatic means are provided to cause the various motions of the heads and bucks. A main conduit 9! acts as a source of fluid pressure. A valve 920a controls that pressure in its relation to the lower buck SIM and the corresponding lower head 9l6a. A conduit 922a connects valve 920a. with a cylinder 9240 from which there movably extends a telescoping piston rod 926a which is attached to the frame of the lower buck 912a. A spring 928a, attached to the frame of buck 912a and upright 90l, tends to hold'that buck in pressing position where it remains unless pushed forward by piston rod 926a. Other means, such as weights, etc., may be substituted for the spring. The valve 92041 is connected through conduit 9300 to chamber 932a which may be supported by frame element 903 and in which there is a piston 934a. A piston rod 936 leads from the piston out of chamber 932a and is attached to the upper head 9l6b which, as described above, is connected to lower head 916a by telescoping tubes 901. A re,

turn conduit'938a leads from chamber 932a to valve 920a and is used, as described hereafter, to remove the pressure from chamber 932a. A check valve 940a in this conduit prevents the passage of fluid except in a direction away from chamber 932a: A vent 942a leads from valve 920a to the atmosphere.

A similar valve 920!) and a set of similar conduits (shown on the drawings with sufiix b) control the fluid pressure which operates the upper head 9l6b. The piston rod 9361) leads from the piston 9342) into chamber 932a and is attached to piston 934a. The motion of the piston 934i) is thus communicated directly to the upper head 9l6b through the intermediate elements 934a and heads need be, under some circumstances, so slight that the headsmay be considered substan tially fixed. The forward motion of the bucks is sufficient to expose their work-supporting surfaces so that an operator has no difllculty in properly arranging the material thereon which is to be pressed.

The structure of the valves 920a and 92% will next be described in connection with the operation of the machine. Assume that the lower buck is back in pressing position as shown and that it is desired to move the upper buck back to pressing position. .The handle 94417 of the valve 92% is moved from its neutral position at which it is normally held by means such as springs, not shown,

to the position marked In. In the neutral position "N, there is no connection between pipe 918 and pipe 922!) and a valve element 94Gb covers the vent 942E which would otherwise be connected by passage 9481) to the return conduit 938D from the pressing head cylinder. In the neutral position, however, the fluid pressure supply line EH8 is connected to the conduit 9301) which carries pressure to the chamber 932!) so that both pressing heads are down in pressing position. As the valve handle is moved to the in position, the element 946D moves away from and uncovers vent 9421) so that the latter is connected, by means of passageway 948b,.to the pressing head chamber vent line 93% and, at the same time, the vent 9421) is also connected by that passageway to the line 9221) which supplies pressure to the buck piston. These pressures having been vented, the springs 905 raise the heads 919a and 91Gb and the spring 9282: is free to draw back the buck 9121) along upper tracks 904b to pressing position under its head. When the valve is in in position, the conduit 930i) is shut off. Valves 950a and 9501) are provided in the lines 9301: and 930b, respectively. There is a connecting linkage between valve 920D and 9500. and between 9200. and 950b. The motion of the valve 9201) to in position causes, through the linkage, the valve 950a to close... This prevents the pressure from line 9l8 passing through pipe 930a from beingvented through 9380. and 93812 which open into each other at the connection 952 and hence out through vent 94%.

The handle of valve 920!) is then released and it automatically returns to neutral position whereby pressure is supplied from line 9 I 8 to the chamber 9321), causing the heads to return to pressing position again. The motion back to neutral position also permits valve 950a to be reopened so that pressure is transmitted against piston 934a as well as against 934b.- As the valve returns to neutral position, no pressure is admitted to the buck piston cylinder 924?). In order to insure that head 9|6b does not come out into pressin position until buck M212 is completely back in pressing position, there is a valve 952!) in the pressure line to the cylinder 93!!) which valve is only opened by the contact therewith of a finger 9541) on the buck 9|2b. This finger can only operate the said valve when the buck has reached its pressing position. The lower buck m likewise is provided with a finger 954a cooperating with.

valve 9520.

The foregoing has described the operation of the machine when the upper buck is moved from work-receiving to pressing" position while the lower buck is .in pressing position. That motion would take place inthe same manner if the lower buck had been .in forward position during the same was against its buck.

time. Ei ther'bucl: may be moved in this fashion while the other is either forward or backward.

A simultaneous manipulation of the valved-by a common element for example, causes both bucks to be moved together to pressing position.

When both bucks are in back position with s" head pressing respectively against each, the operation of parts to bringeither buck forward to" work-receiving position while the other buck re mains back in engagement with its head is as fol ator is free to press various smaller parts of another similar garment. The machine described above permits this to be done. Neither the buck nor the operator needs to be idle because the other buck has not finished its pressing in any particular case.

Since certain changes may be made in the above construction and different embodiments of the T invention could be made without departing from lows. vAssume buck 2b is to be brought for.- I

ward to the position shown inwl 'ig. l0. Valve 82th is turned to out position. (1) This motion shuts ofi conduit 98Gb from fluid pressure supply line M8; (2) It operates valve 980a and shuts oil conduit 930a from fluid pressure supply line 9l8. (3) It uncovers the vent 84th which thereby opens into passageway 8b. This vents cylinder 93% through conduit 838D and cylinder 9820;

through conduit 938a which is always connected lift both heads off the bucks. (4) It connects line M8 through conduit 9221) to the upper buck cylinder 92 db whereby pressure entering therein pushes out the piston rod 9281:. Buck Qlfib is thereby pushed forward on upper guide tracks 90th to work-receiving position.

The valve 92% is then allowed to snap back to neutral. Thereupon, (1) element 94th covers vent 962b, permitting pressure to be built up again in the head cylinders if and when it is reintroduced there; (2) pressure is reintroduced from source tit intoconduit 98th as far only as valve 95217; (3) valve 95%. is returned to open position, introducing pressure again into conduit 93% and head cylinder 932a. This causes both heads to lower to pressing position but with only half as much total force as when pressure was in both head cylinders @3211 and ease and when each head By a similar motion of valve tide instead of valve 92%, buck 912a may be brought forward instead of buck tifib or by a simultaneous motion of the valves, both buck may be brought' for wardsimultaneously.

It is intended that both tracks ease and tilt!) should be not far fromeach other and that the front ends of both should be at a position con; venient for loading by an operator Should the lower/tracks be too low for convenient loading,

means may be provided (pistons, linkages, etc.) for raising the lower buck when it reaches the front end of the lower tracks. 01', should the upper tracks be too' high for convenient loading,

, It is often advantageous to have apart of the press in pressing operation fora long period while another part performs successive. shorter p .acts. Thus, one part of a garment may be heavier. and need a longer pressing, or it may need a more.
