Application filed July 12,

To all whom it may concern:

Be it known that I, ALFRED EILERT, a citizen of the German Republic, residing at St. Louis, Missouri, a certain new and useful Improvement in Pressing Machines, of which the following is aspecification, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention: relates to new and useful improvements in pressing or ironing machines, and the objects of the invention are to provide a pressing machine having a plurality of work supporting forms or boards, said boards being of various shapes and sizes for receiving various garments and parts thereof.

ating engagement Further objects of the invention are to provide a pressing machine having a plurality of interchangeable supports or boards which can be easily laced in operating position and can be readily brought into cooperwith the iron which is adapted to receive reciprocating motion. Still further objects of the invention are to generally improve upon and simplify the construction of the pressing machines and provide suitable mechanism for controlling and actuating the same.

With these and other objects in view, my

- invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a top plan view of a pressing machine.

- Figure 2 is a front elevational view ofthe same.

Figure 3 is a vertical cross section taken transversely through the machine.

Ilgures 8 to 10 are plan views of various interchangeable ironing boards.

'Figure 11 is a cross sectional detail view illustrating means for supporting the removable boards in position on the machine.

U. S. A., have invented these boards 20 is provided and pressing pleated material, the fold of 1924. Serial No. 725,546.

Figure 12' is a detail view showing means for maintaining the board supporting memher in operative position.

Referring by numerals to the accompanying drawings, 10 indicates the side frame members connected by a rear frame member 11 and a front cross member 12. The side frames 10- are provided with vertically disposed slots 14 in which are mounted for vertical movement bearing blocks 15 receiv ing trunnions 16 of a revoluble member 17. This revoluble member has a polygonal peripheral surface and is preferably triangular in cross section, thereby providing a series of tables or. work benches 18 and 18 and 18, as shown in Figure 3 which support an ironing board 19, a shoulder lining ironing board 20, and a pleated goods ironing board 2l,respectively. Ironing board 19 is supported on the bench 18 by a removable bracket 19 while board 20 is detachably held in position on the bench 18 by a leg 20* which is non-circular in cross section and fits in a socket 20 secured to bench 18". A series of they are formed of various shapes and sizes in order to enable the operator to select the proper board for ironing shoulder linings and other portions of various garments. Ironing board 21 is also provided with a depending leg 21 which fits in a non-circular member carried by the bench 18 and detachably "supports said board thereon. Boards 21 are used in connection with ironing pleated material, such as skirts. In

the

socket I upper or overlappin pleat leaves a line or mark on the lower p eat and it is necessary to press each pleat separately, after pressing the garment, in order to remove this line or mark. Boards 21 are provided in various widths in order .to permit ironing pleats of various sizes.

To prevent displacement of the board, the legs thereof can be locked in the socket members in any suitable manner, such as by means of a thumb screw 22shown in Figure 11.

' An iron 24 heated in any suitable man-- ner, preferably by gas, supplied by connection'24 is disposed a suitable distance above revoluble member 17 and is adapted to be engaged by one of the ironing boards, which, when member 17 is raised, presses against the lower face of saidiron. This iron 24 is supported by the downwardly curved ends Cal of arms which have their opposite ends secured to a horizontally disposed bar 26 slidably arranged in bearings 27 which are fixed to rear frame member 14. Bar 26 receives reciprocating motion through a crank arm 28 connected to said bar by a link 29 and fixed to a shaft 30 which is operated by motor 31 through suitable reduction gearing 32.

When the machine is in operation, iron 24 is constantly moved back and forth over the garment pressed thereagainst by one of the boards and thus the garment is ironed in an efiicient and economical manner. cross bar 34 is secured at its ends to extensions of side frame rides sliding support for members 35 car- 'ried by arms 25.

Means for raising member 17 into operating or pressing position comprises a oot board or pedal 36 secured to the outer ends of levers 37 which are pivotally mounted at 38 in the side frames 10 and have their inner ends pivotally connected to" the lower ends of links 39,- the upper ends of which are pivotally connected to extensions depending from hearing blocks 15. When pedal 36 is depressed, the inner ends of levers 37 are raised and causes member 17 to move upwardly, whereby one of the ironing boards is pressed against the longitudinally movable iron 24. The degree of pressure with which the ironing board is held against iron 24 can be regulated by increasing or decreasing the pressure applied to the foot board 36. Counter-balance weights 40 are suspended adjacent to each side frame member from one of the ends of cables 41 which extend upwardly and pass over pulleys 42 secure to the side frames and then extend downwardly and have their opposite ends attached to lugs formed on the ends of levers 37, thereby balancing said member 17 and facilitating the movement thereof in a vertical plane.

The various ironing. boards are spaced or raised from their respective tables the usual distance in order to provide suflicient clearance for properly arranging the garment in position on the board. Therefore, it is necessary to space supporting members 17 a suitable distance from the rear frame member 11 in order to provide suitable clearance for said ironing boards when member 17 is rotated to place the proper ironing board in operative position. To prevent the garments from entering this space, and also to exclude dust from passing downwardly, a shelf 44 is arranged rearwardly of member 17 and in a horizontal plane with the upper face or working table thereof. This shelf is pivotally supported at its ends by brackets 43 which extend rearwardly and upwardly from bearing blocks 15 so that when the members 10 and pro-- the various ironing roller 51 carried and other foreign material member 17 is raised, shelf 44 moves with it and is therefore maintained in proper position relative to the respective table of member 17. \Yhen member 17 is rotated so as to position a different ironing board for cooperation with the iron, said shelf is tilted upwardly so as to permit the respective board to traverse the space between member 17 and the rear frame element. in order to provide an automatic opening or tilting of shelf 44, a cam 45, having three depressions arranged in its periphery in .a predetermined relation with the tables of member 17, is provided and cooperates with a roller 46 carried by an arm 47, which latter is pivotally mounted on bracket 43. This arm is connected by a link 48 to a depending arm 44 of shelf 44 whereby, when roller 46 enters one of the depressions on cam 45, arm 47 is moved rearwardly by a spring 49 and causes shelf 44 through its interengagement with link 48 to be rocked upwardly out of the path of movement of one of the ironing boards when the member 17 is rotated. Cam occupies, a fixed relation relative to member 17 and is arranged so as to actuate arm 47 in proper timed relation with the movement of boards so that shelf 44 is lifted and moved out of the way of the respective boards at the appropriate time.

The centering and locking means for member 17 comprise a three-way cam 50 fixed to one of trunnions 16 and having lts periphery engaged by a pressure foot or by a plunger 52. This plunger is slidably mounted in a sleeve 54 and is yieldably forced against said cam by a spring 55 arranged in said sleeve. Sleeve 54 is carried by and fixed to one of the bearing blocks 15 and consequently occupies fixed relation with respect to member 17 and its work tables.

The pressure exerted by the spring pressed plunger against cam 50 is sufficient to prevent accidental rotation of member 17 and also serves as a brake for preventing over rotation of ,said member 17 The disposition of the three pockets or de pressions on cam 50 is such that when one of the pockets is in alignment with roller 51, the respective table occupies proper working position.

The lower ends of slots 14. are preferably provided with pockets 56 in which are disposed comparatively small coiled springs 57 which, when member 17 is restored to its downward position, are adapted to be engaged. by hearing blocks 15 and act as shock absorbers and eliminate jarring of the machine and prevent damage thereto.

A pressing machine constructed according to myyinvention is highly efficient in operation, is particularly well adapted for use in ironing various articles without nework bench cessitating changes or adjustments of the machine and is so arranged that it can be operated and controlled without manipulation by the operator, therebyleaving his hands free for adjusting and operating upon the article to be ironed.
