The present invention relates to pressing machines and more particularly to "a universal control for the pressing iron of such a machine.

Some of the objectsof the present invention are to providc'an improved mechanism for pressing cloth and other material in tailoring establishments, clothing manufacturing and many other industrialplants; to pro- 'vide means for supportinga pressing iron position, for. more effective and efficient operation;'to provide means for automatically handling-the weight of a pressing iron to relieve the operator from the labor of controlling such weight; to provide a support fora pressing iron whereby the range of movement-of such iron is materiallyincreased and variations of the ironing stroke can take place from a minimum to a maxiv mum; to provide an improvedmecha'nism for applyin a constant pressure to goods being pressed; to provide means for anch0ring a pressing iron in one pressing position to carry out a pressing operation while allowing the operator the freedom of both hands to arrange the material being pressed; and to provide other improvements as will herei'nafter appear.

In the accompanying drawings, Fig. 1 represents a perspective of a pressing machine embodying one form of the present invention; Fig. 2 represents a'sectional side elevation of the same; Fig. 3 represents a sectional'detail of a bearing head; Fig. a represents a section on line lilot Fig.3 ;"Fig. 5

represents asectional detail of the head support; and Fig. 6 represents a' detail in side elevation of a modified form of head locking 'means. v i Referrmg tothe drawings, one form of the present invention is shown as applied to a steam pressing machine consisting, as generally con'sldered of aframe'l'O supporting a table or bed 11 and upon which is mounted a buck or pressing board 12. When the.

goods are placedupon thepressingboard 12 and suitably arranged for the pressing operation, a sad iron 13 isjbrought into pressing. contact with thermajterial and: since ity is heated in the usual manner of such irons by a burner receiving its gas supply by way of a pipe 14 and a steam supply by way of a pipe 15, the goods are .not only heated but receive the required moistening effect to prevent scorching. A handle 16' is attached to the iron 13'for manipulating it and, as here shown, is disposed at a' convenient operating angle toward'the operator. p v

For supporting the iron 1'3 so thatit has a movement not only universal in a horizontal plane but also so that it 'cianbe raised or lowered vertically, itis connected by a ball and socket joint l'Zto, a rod 18 which is. sus pended from and rigidly attached to a hanger arm 20'which, in this instance, is of generally rectangular shape and arranged with its edge parallel to the table 11. The support for the arm 20 consists, in the present instance, of a head 21 providedat opposite ends respectively with slots 22 which are vertically disposed to form guide openings for-the arm 20 which traverses the slots 22 in vertical edge relation. that is to say I the arm 20 for strengthening purposes has its sides in a vertical plane. In order that the arm 20 can move'relative to the head 21 easily and with a minimum amount of friction, the lower .portion'of thehead 21 carries a track 23'wlii'ch supports a plurality of. ball bearing rollers 23t0 serve as movable bearings upon which the arm 2O rides. The track 23 is preferably adjustable as shown by the set bolts25, in 7 order that the bearings can be maintained in contactwith the arm 20, or compensate; for wean, The upper portion of the head 21 is likewiseprovided with a track member 26 having bearing rollers 27 held in engagement with the upper edge of the arm 20 to thus not onlyresist any tendency of the arm to deflect upward but also to provide a free easy running bearing. Adjacent one of the slots .22 thereis a projecting bearing lug 28 located above the arm 20 and in position to contact therewith, while atithe opposite end of the head there is a second lug 30: projectingto engage the lower edge of the a'rm 20, these lugs forming abutments to resist any tendenjoy of the arm 20 to distort'vertically p e In order to prevent lateral play of the a'rm 20, angleplates 31 are adjustably'mounted in pairs at opposite ends of the head 21, each pair being spaced to receive the arm 20 between them and fit snugly against tl e sides thereof without frictional engagement.

For the purpose of supporting the head 21 for swinging movement in a horizontal plane, it is provided with a rigid bracket 32 project ing laterally therefrom and terminating in a hub m'e'inb r hich is fixed stud bolts 34 to a vertically disposed post 35. This post 35 forms the axis of rotation for the arm 20 and head 21 and to that end has its upper end journalled in a thrust bearing formed in a cap 36 and its lower end journalled on step bearing formed by a cap 37 fitting over a ball race 38 which is held in interfitting relation by aspring 40, the lower end of which seatsin abase socket 41. The cap 36 is bolted to a boss 42 projecting from a main rock arm 43 to fit about the post 35 while a set screw 130 is threaded through said cap in co-anial relation to the post and engages a plate 131 restingon a ball race 132. 7 On the upper end of the set screw is mounted the usual sponge cup 133, which serves a means for adjust ing the setscrew. A wing nut 134 is adapted to lock the set screw inthedesired adjusted position. A second boss 44 also pro ects from the rock arm 43 to fit about the lower portion of the post 35, the two bosses 42 and 44 serving to transmit motion of the arm 43 to the post 35 while allowing the latter to have free rotary motion. 6 The arm 43 serves as a relatively large bell-crank pivoted at 45 to the table frame, the head operating end of which extends substantially vertically at the rear of the machine and its other end passing substantially horizontally under the table 11. The purpose of the vertical ustment of the post 35 is to permit the iron 13to be adjusted to'eflective pressing position when the usual padding on the board 12 becomes compacted during use. This takeup permits at all times eiiective pressing action without any lost motion.

For actuating the bell-crank 43, its horizon;

tally arranged end is connected by links 46 which straddle a rock lever 47 and are connected thereto by a pin 43 located lntermediate the fulcrum 50 of thelever 47 and its pivoted connection 51 with an actuating rod 52. This last joins atreadle 53 pivoted to a bracket 54 depending from bracing frame 55 of the frame 10. Pivoted to the treadle 53 is a weighted latch 56 arranged to fall just beneath the front edge of the bracing trame 55 when the treadle is depressed in order to lock thehead and sad iron in their pressing position. A dog 57 ispivoted to the latch 56, and in one position is ineffective, in so far as, the latch '56 is concerned, but when manually turned in another position, one end swings between the latch 56 and the treadle 53 and prevents the former from falling to latching position. A foot piece 59 is pivoted 7 look sothat the toggle is broken. the toggle structure to maintain the position locking the: treadle. 53 down, the upper end .boss 58 and the juxtaposed head 61 is a coil spring 62 arranged under compression, and the construction is such that release of the treadle 53 allows the two relatively heavy springs 62 to rock the bell crank 43 in the opposite direction to release the iron pressure. In operation the goods to be pressed are placed upon the buck 12 and the iron 13 is grasped by the handle 16 and brought to the desired position above' the goods. This movement is merely a swinging one because the iron is normally supported above the plane of the goods by the arm 20 and the rock arm- 43 under the influence of the weight balancing springs 62. Since the radius of the arm 20 is variable, due to its sliding connection with the head 21, it will be apparent that the iron can not only be moved about the,

post 35 as an axis but can also'travel in a straight line longitudinally of the buck 12. ith the iron brought to position the treadle 53 is act .ated to press the iron downward upon the goods when it can be automatically.

held by the latch 56 dropping under the front bar of the frame 55. When the iron is so locked exerting pressing pressure upon the goods, the operators hands are free to manipulate and arrange the goods for pressing other portions thereof. By actuating the foot piece 59 the latch 56 is released to permit the iron to be lifted and moved to a new pressing position.

V In the formof the invention of Fig.6, a toggle locking control for the treadle 53-is shown comprising a pair of levers 63 of like size and shape pivoted respectively on opposite ends of fulcrum pin 50' and having one pivotal connection at 64 with a lug 65 prolinks 68 which in turn are pivoted on a pin 7 O passing through a bearing ear 71. Pedal members 72 project from opposite sides of the lever in orderto kickout and release the To assist of one of the levers 63 is provided with a lug 73 to which a spring 74 isattached and is stretched to a fixed part of the machine. WVhere it is desired to maintain the toggle broken so that the head 21 is not mechanically held down, the end of the spring 74 is transferred to a pin 75 on the opposite side of the fulcrum 50 and hence its tension acts to hold the levers 63 and 66 in open position with the treadle 53 free for manual operation. lVith the spring 74: on the pin 7 3, the toggle levers 63 and 66 are thrown to locking po sition whenever the treadle 53 is pressed down and hence the iron 13 can be freely ma- I nipulated by the operator without maintainmg foot pressure upon the treadle. Being thus relieved of physically holding the treadle, the operator is unhampered in handling the iron and arranging the material being pressed. At any moment the toggle lock can be released by a kick upon the member 72.'

It will now be apparent that a complete unitary pressing mechanism has been devised whereby a pressing iron is supported in a manner to relieve the operator of its weight and does not have to be manually lifted in order to reach its pressing position. Also the rangeof movement of the iron is mate rially increased over anything heretofore de-- vised and with the increased range comes a variable radius of movement which provides universal action in a horizontal plane.

lVhile only a single form is shown in which this invention may be embodied, it is to be understood that the invention isnot limited to any specific construction, but might be applied to various forms without departing from the siprit of the'invention or the scope of the appended claims.

Having thus described my invention, I claim: r V
