13 Claims. e

This invention relates to a `multiple buck, single head'pressing machine.

One chief object of this inventionis to provide a two-station pressing machine wherein at one station garments and the like may be pressed while other garments may be otherwise handled at a second station. l Another chief object of this invention is to provide a press capable of being operated by..a single operator at asingle station.

A further chief object of this inventionvis to provide a press capable of such operationv and nance thereon, said bucks being cyclically mov-al `able from station to stationab'out a horizontal axis, thereby distinguishing from a turret type press wherein the bucks `are always coplanar and rotate about a vertical axis.

` Other objects and features of the invention will be set forth more fullyhereinafter. l The full nature of theinvention will be understood from the accompanying drawings andthe tation of thefbucksl `fronrone station to another.

lig. 2 is a `front elevation of the bucks andfl connections and in aposition midway between theoperating stations.

Fig. 3 is an end view of the bucks asshown in Figa H f e arged "axial sectional view through one end of a buck pivotal support.

lFig. `5 is a similar view through the central pivotal support ofthe multiple buck arrange- Fig. 6 is a diagrammatic elevational View of a power kick-off mechanism for initiating buck In Fig. l, the numeral" I' indicates a frame structure upon which is suitably supported a pressing head II having a flexible steam supply line I2 suitably controlled by valves as at vI3 and I4. The head is adjustably supported at I upon `an arm structure` I6 pivoted on frame IIJ atI'I.

Upon extension Illa frame I 0 is pivoted at I8 a rocker structure I9v connected at `oneend -by link to the head supporting arm I6. The opposite end of the arm I9 mountsroller 2| arranged for cam operation, see cam 28.

The arm I6 is extended and upon the extended `end 22 is secured a tension spring structure 23 which' normaly constrains the head II to elevated position-see dotted lines, Fig. 1. v Apressure cylinder 24 is pivoted at 25 to frame IU. It includes a piston-not shown--mounted on rod 26 which supports at 21 a cam 28 pivoted at I'I. The aforesaid is broadly disclosed in Patents No. 1,888,163; No. 2,053,366 andNo. 2,062,745, so no further detailed description of the same or minor associated parts is believed necessary for an understanding of the present invention.

When there is no pressure in cylinder 24, spring `23 pullsdown upon end 22 rof `arm I6 to raise the `head supporting end upwardly into the dotted lline position, see Fig. 1. When pressure is applied to cylinder `24, the piston therein raises with the rod 26, and tilts"at 25 as required, and in such movement, cam28 pivotsy on II and rotates counterclockwise `and upwardly. In this movement roller 2I with arm I8 is rotated counterclockwise about pivot I8. Since link 20 connected a'rms I9 and I6, the latter, despite the constraint of spring 23, is caused to move downwardly from the dotted line to the full line position carrying with it the head II until the head engages buck 6U, then properly and rigidly positioned for pressing engagement, the pressure applied for pressing being determined by several adjustments.

Pivotally mounted at 29 on frame I0 is an up- ."right or brace member 30 having the seat portion 3| andguide or cam portion 32. The casing, also of frame character, is indicated by numeral 33 and pivotally supported thereby at 34 or any other suitable support is a treadle type lever 35 having the machine exposed, operator-operable, `foot engageable portion 36. The opposite'end of said lever is connected to link 31 pivotally connected at its opposite end to the pivotally connected adjacent ends of oppositely directed links 38 and 38 and as at 40. Link 38 at its opposite end is pivoted at 4I to brace 30. Spring 50 normally constrains lever 35 to elevated position, if

the weight thereof be insufficient. Pivotally supported in frame Ill as at 42 is a Alever 43 pivotally connected at 44 to the other end of link 39. When the treadle 36 is depressed, the link 31 elevates which forces the links 38`39 upwardly into inverted V-relation as shown by dotted lines in Fig. 1. This breaking of the toggle linkage draws brace member 30 rearwardly straightened, when the treadle Yand moves therewith.

and necessarily slightly downwardly, dotted lines to the right of the full lines in Fig. 1 indicating this position. This is the non-supporting and buck clearing position to which reference hereinafter will be had more fully.

A master valve housing structure 45 is carried by frame I 'and a flexible connection 46 connects the cylinder 24 thereto. The pressure supply 41 is controlled as at 48. 'I'he master valve housing includes two valves, the stems of which are indicated by numerals and 52. Frame I0 carries spaced stops 49 and 53 which limit the oscillatory movement of member 43 about pivot 42, which oscillatory movement results from movement of link 39.

Member 43 has a contact head 54 of yielding character or yieldingly mounted and an extension I 43 of member 43 mounts a similar structure 55 in similar manner. Therefore, in the movement of member 43 for pressure control of cylinder 24, these two valves (stems 5I and 52) are alternately operated for pressure and pressure release to permit raising and effect lowering of the head I I.

The stop 53 cooperates with member 43 to insure breaking or collapse of the toggle joint 38-39 when the treadle 36 is depressed and link 31 is 'elevated so that the brace 30 can move rearwardly, constrained thereto by gravity, rather than the toggle bodily moving forwardly while is depressed. Hence, breakage of the toggle joint is assured and the brace is positively tilted rearwardly by treadle depression.

Reference now will be had more especially to Figs. 1 to 3, inclusive, wherein there is illustrated a pair of bucks 60, each supported by neck 6| on cross member structure 62 from which centrally depends arm 63 which mounts roller 64 on pivot 65. A shield 66 is secured to each buck assembly It has a hand grip portion.61 to facilitate initiation of buck movement.

Secured to the opposite sides of the casing 33 and directed inwardly are the elongated bearings 68, see Fig. 2. Rotatably mounted therein is the `shaft 69. Sleeve 1lisee Fig. 5-may be provided or omitted, or replaced by an anti-friction structure of roller type.

Each end of the shaft 69 is longitudinally bored as at 1| and cross-bored as at 12. Each end thereof supports a connection 13 comr municating with the conduit 14. The other end of the bore receives a tube 15 and the extreme end of the bore is enlarged as at 16 to receive a spring 11 bearing on face 18 at one end and on washer 19 at the other end. The latter bears on the packing 89. The extreme outer end of shaft 69 is threaded as at 8| to receive the retainer 82 through which projects tube 15. The outer end of the latter is threaded and is connected to the conduit 83 as by fitting 84. Thus, shaft 69 may rotate without rotation of tube 15 and the connection therebetween is leak-proof.

Referring to Figs. 1 and 2, it will be noted that adjacent the conduit 14 connected to the shaft at each end, there is secured an I-beam member 85 that rotates with the shaft 69. Each end of these 'beams terminates in a bearing 86, sleeved as at 81, see Fig. 4. Similar ends of opposite beams have these bearings 86 aligned and therein is mounted a shaft structure 88-89-see Fig. 4. Tube 88 is utilized to reduce weight and mass. Plugs 89 provide end strength and are bored L-shaped as at 00, the shorter length being transverse to the shaft axis and receiving fitting |09 to which conduit I I0 is connected.

Since all four ends of the two shaft structures 88-89 are identical, further reference will be had only to that illustrated in Fig. 4. In a manner similar to that illustrated in Fig. 5, the coaxial length of bore 90 is enlarged to receive tube 9 I, and is further enlarged as at 92 to receive the spring 93 bearing at one end on face 94 and at its opposite end on washer 95. A closure 96 threaded to shaft 89 retains packing 91 and tube 9| extends through the closure and is connected by tting 98 to tube 14. Thus, shaft structure 88-89 may remain stationary, relatively speaking, as to rotation, yet revolve as now set forth.

Secured to the interior face |00 of each bearing 68-see Fig. 5-are studs |6| which anchor and by means of spacing sleeves |02, the sprocket |03 with central opening |84 and peripheral teeth |05, the sprocket being spaced from the bearing 88 and adjacent the beam 85. Mounted on said sprocket is chain I 06-see Figs. 1 to 3.

Rigid with each shaft 88-89 and on the free end thereof or exteriorly of the beam bearing, is sprocket IUT-see Fig. 4 and Figs. 1 to 3-and the chain |06 meshes therewith. The sprockets |03 and |01 lat each side of the machine are of coplanar alignment.

It will be apparent from the foregoing description and the drawings that when the adjacent hand grip portion 61 of the shield is tilted upwardly when brace 30 is released that the buck 60 immediately adjacent the operator with the garment thereon is moved upwardly and rearwardly in the direction of the arrowsee Fig. 1-and that by reason of the sprockets and chain mounting, the buck 60 will always maintain a position wherein the upper surface of the buck always is positioned upwardly. This is because sprocket |03 at each side of the rotatable structure is stationary and the chain |06 rolls thereon. Necessarily in the l.rotational movement, since the sprockets are of equal pitch and diameter, the shaft structure 88-89 rotate correspondingly in the first mentioned rotation which may be termed revolution so that the bucks always will be upwardly directed, irrespective of their revolved position and as illustrated by the dotted lines in Fig. 1.

In this connection it is to be noted that one of the conduits 84 at one end of the central shaft structure is an intake structure and the opposite one is an exhaust structure, and the respective conduits 14 from the respective intake or exhaust structures lead to the opposite ends of the revolvable shaft structures 88-89. The L-shaped bores 90 communicating with conduit 14, as aforesaid, connect by lines |0 and the extensions |08, shown dotted in Fig. 2, to the interior of the buck structure. One of these connections is of the steam supply type and the other is of the exhaust type. Thus, steam may be applied to each buck and exhausted therefrom. Thus, steam for heating purposes is always supplied as long as the valve |4 is open, it being understood that the line |3a is arranged to communicate with the supply line which may be the right hand conduit 84 in Fig. 2.

By referring to Fig. 1, there will be observed, immediately to the left of the member 30, a dotted line representation thereof and attention also is called to the dotted line representation to the right of the full line representation of the member 30.

When the treadle 36 is depressed, the brace structure 30 beneath the roller 64, carried by the depending arm 63, is retracted to the right hand dotted line position. When this has been effected;

it also is `to be observed `the headstructure can braceportion 30. This rotation is continued and asthe previously left hand positioned buck moves into the position almost that illustrated bythe right hand full line buck in Fig. 1 andthe treadle is released, theroller 644 engages the cam face 32,

because upon release ofthe treadle, themember 3|) `has moved to its eXtreme counterclockwise tilted position-shown dotted in Fig. 1 and to the left in advance `of the full line position-and in that subsequent contact the brace member 30 returns to` the full line position shown in Fig; 1. This maintainsa rigid bracing arrangement for the buck beneath the head structure I or in the pressing position. Thereupon the head structure is lowered, as previously described, and pressing of the `garment on the right hand buck 60 yiseiected.v When this has been accompli'shed, the treadle is actuated for the aforesaid release, as described, and the bucks are again revolved manually.

` If desired, power means may be provided for initially `revolving the bucks and these may be treadle actuated or otherwise. In Fig. 6, there is diagrammatically illustrated such a kick-off mechanism. Shaft 69 supports, preferably centrally, two oppositely directed bracketsor` lugs |20, the same beingxtransverse to the beams. j Eachlug isreduced as at |2| and pivotally supported aty |22a in the recess is a bar |22 which engages a stopextension |23 on lug |20. Member 4|22 is normallyconstrained into stopengagement by spring |24 anchored to angle support Adjacent the normal-lower position assumed by such structure in its rotation,` isv a stationary cylinder |25lwithbleed port |29 and piston |26 4 with the rod |26a extended therefrom as shown. i Piston |26 is normally constrained by spring |21 toward the right. `Pressure inopposition thereto is supplied as at |28 at the appropriate time to `cause rod |26a. to engage bar |22 to initiate clockwise revolutionof the bucks.` In this rotation of shaftli, the approaching bar |22 engages stem |26a and the bar tilts counter-clockwise until it clears said member |2611. When thus clear it returns to original position and is positioned for subsequent piston rod engagement.

that the operator may stand immediately' to `the left of thefoot treadle 36land iron finish thegarment, previously pressed, as to such portions` as limitation l. on production is `that determinable by the headpressing cycleplus the time required "From theforegoing, therefore, it is obvious for Mrevolution ofthe bucks from oneposition to another. r l l lThisinvention also has the advantage that it occupies-appreciablyless floor `space than that of a turret type, multiplebuck press structure, wherein'the turret rotates about a vertical axis and presents the several bucks in succession to one or more pressing stations.

7 The'present invention furthermore has this advantage over theturret type `structure mentioned,` inthat the supplementary ironing can be effected on the garment previously pressed immediately following pressing and vthus the interval that is normally required for moving a particular buckfrom the pressing station to the unloading station in the` turret type device is materially vreduced and'substantially eliminated, it being understood that such turret type devices usually include four 0r more horizontally rotatable bucks per turret. l

The other advantages previously mentioned i l hereinbefore are all effected by this invention.

lIt will be noted, see Figs. 1 and 6, that member |46 is mounted so as to be engaged by brace 3U when in fully retracted and non-supporting position. Member |40 is-see Fig. g-constrained to closed valve position by spring |4 I. The valve is indicated at |42. Thus, operation of piston |26 is automatically controlled by brace movement so that-revolution cannot be automatically initiated or attempted until the buck 'assembly arrangement is freed vfrom the locking brace 36.

Itwill be remembered the `buck assembly arrangement may be manually revolved. Hence, in `case the head jams, whichiwould interfere with buck revolution, means is `provided `to prevent buck `revolution until the head has sufficiently elevated to not `interfere with buckmovement.

One simple form of interlock `includes member |60 pivoted to the frame at |62 and constrainedto brace locking position by spring |63.`

The angular end |64 of member |66 is positioned adjacent brace `3l!.\` |66"is connected by link |65 to the'end of member |6-22. Thus, when member|622 is elevated (rotated clockwise) link |65 rotates member |60 counterclockwise in opposition to spring |63 and retracts the brace lock |64, permitting the brace 3D to move, toits right `hand dotted line positionsee Fig. ;1-which permits buck arrangement revolution.` Any other suitable head associated brace lock may be employed in lieu of the foregoing.

While the invention has been illustrated and described in great detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character.` A
