vIIItONINCt-MACHINEi Specification of Letters Patent. i Patented Aug.. 16, 1910.,

Application led July 13, 19.07. Serial No. 333,535.

To all whom fit may concer-n:

Be it known thatwe, DAN. H. BENJAMIN and JAMES W. GILBERT, citizens of the United States, residing at Lebanon, in the county of Lebanon and State of Pennsylvania, have invented certain new and useful Improvements in lroning-l\lachines, of which the following is a specification, reference being had therein to the accompanying drawing.

Our invention relates to an improved ironing machine, and we declare that the following is a full, clear, concise and exact descripltion thereof, sufficient to enable one skilled in the art to mak-e and use the same, reference being had to the accompanying drawings in which like letters and numerals refer to like parts throughout.

The invention is here shown as applied to "a press constructed for laundry work and includes among its features new mechamcal4 appliances in a new arrangement whereby .we are enabled to app-ly great power in .the work of themachine and at the same time to remove the .upper presser sutiiciently from the lower plate to allow free access for the work. l

In the drawings Figure 1 is a side view of the press; Fig. 2 is a front view of the same, and Fig. 3 is a rear view, broken lines in certain of the figures showing parts removed. Fig. Llis a detail view of a plate which is lowered upon the shirt bosom after it is laid on the felts or other covering of the lower plate; Figs. 5 and 6 are details' of the connections between the upper presser-plate and the operating link connected therewith,

showing the bearing of the latter on the former g'Fig. 7 is a detail view, looking down from above, of gear mechanism for reversing the operation of certain parts.

Referring to the drawings in detail, the machine comprises a frame which is indicated by A, on which are mounted secondary frames to support particular parts and which will be pointed outI later. The frame comprises a lower stationary plate B having a smooth plain 'surface and recessed interiorly, as indicated at C, into which space are passed steam pipes D for the proper heating of the plate. The. frame also comprises rigid arms E "one on each side of the machine, mounted on the framerk and which supports the movable upper plate or presser F which is pivotally supported by the arm F extending from one side thereof and preflceive the same. `also has upright lugs 12 which lie along-side erably integral therewith and journaled in the arms E.

Un the sides of the machine towardthe front and adjacent the bottom is pivotally mounted a yoke G. This yoke is journaled at 1 and has corresponding side members and is suitably strengthened by braces 2 and has a transverse beam 3 at the top at the middle point of which swingably depends link 4e supported on a shaft 5 mounted in the transverse beam 3. As the middle portion of this cross beam 3 is cut out for the support of the link 4C we provide a brace of lugs 9 and through which is passed on each side the pin 13 to journal the yoke and the presser together, the axis of the bolts 13 being coincident with the line on which the knife edge plays in the groove 11. By this construction we retain all the effect. of the bearing but obviate the necessity of feeding the same with oil. A particular feature 'of the bearing which the plate F has on the arms l@ is the fact that the bearings in the arms which receive the shaft 15 in arm F are slightly elongated vertically. rl`his permits the upper presser plate F to be swung on the bearings. The lower presser plate B is :normally provided with felts M for the support| of the goods to be pressed and when the upper member is brought down upon the goods its pressure would not be perfectly parallel with the surface of the lower member if the journals were rigidly held. lt is for that reason that the bearings are slightly elongated vertically, 'as indicated at 16, so that the free movement of the upper member in purely7 vertical direction is permitted by the elongation of the bearings. N

lirthe frame vis mounted ashaft on which is mounted gear-wheel 21, and from the gear wheel to the yoke (5r is a pitman mounted on boss 24 on each side of the wheel 21, each curved outward near the end and terminating in sleeve 25 by which it is mounted on the shaft 26 extending transversely from one portion G- of the yoke to the other. The pitman has an intermediate stud 27 connecting the parts to give rigidity.

I It is to be noted thatthe arm or yoke G swings on center 1 while plate F swings on center 15, the yoke andthe -plate being conf nected by link 4. The centers are so located that the swing of the yoke, while it carries the plate F over into pressing position, also, in its full movement, forces plate 'F into pressing action. That-is to sav the construction and arrangements of these members is such that the upper presser is brought into place and forced into action by one movement or operation of the device,

" la single mechanism performing the two op- "ltaption's which have customarily been done iiil` two distinct operations by several devices or mechanisms. i y

A shaft 30 (Fig. 3) is mounted in the frame on which is lpivotally suppoited a gear frame 31 having a lower depending arm 32 which .is provided with a pin 33 to engage arm 53.- The shaft 30 supports in the gear frame a gear 34 which meshes on-one side with the gear 35 and on the other side with a train of gears 36 and 37. In the normal position of this gearfframe none of these gears is in contact with gear 21, but in one operative position the gear 35 meshes with gear 21 and in the other operative position gear 37 meshes therewith.

The power of the machine is applied through shaft 30'by suitable means, which need not be. particularly shown or described, so that when the gears are in the position shown in Fig. 1, the gear 34 is turned in the direction indicated by the arrow and gear 35 is likewise turned in the direction there shown which turn gear 21 as indicated by the arrow thereonf In reverse position gear 37 is in contact with gear. 21 turning it in opposite direction. Suitable means are provided in connection with the gear frame to maintain itnormally in neutral position, as

' for instance, a spring 38.

Mounted rigidly on the main frame is an arm 40 which carries swinging arm 41 which extends upwardly and terminates in an elbow 42. At the opposite end the arm is provided with an elongated slot 43. On the gear Wheel 21 are mounted studs 44 and 44a one of which, as the wheel is revolved, its

movement being reciprocal through half a turn, contacts with the elbow 42 on one surmounted link connection 52 lcarrying link 53, the lattermember extending to the rear of the machine and being provided with square cut-out 54. Bracket 55 is mounted on the frame and has two intermcshing gear wheels 57I and 58, each of which has an extended ange 59 and 60 notched at G1 and 62. On the link arm 53 is mounted gravity dog- G3 pivoted at 64y whose movement in one direction is stopped by pin G5. Mounted on one end of the dog is a pin 66 adapted to engage in cut-out 62. On the opposite side is a like' dog 67 with lug or pin 68 and likewise stopped by pin (3S) and whose lug or-pin (38V is adapted to register with the cut-out 61 in the flange of gear 5f). The shaft which carries arm 41 on the bracket or arm 40 is provided with a spring 40a which normally keeps the elbow on the upper end of the arm inward to be engaged by one or the other of pins 44 or 44" In the position of the parts shown by full lines in Fig. 1 lever 51 has been thrust from the operator, the notch in link 53 has engagedY stud 33 and shifted the gear frame and put gear 35 into engagement with gear 2l when the gear wheel 21 will start on a 'half turn in thedirection shown by the ar- -stud 44a`on wheel 21 has come to contact with edge 45 on the arm 41 it rocks that arm and turns wheel 58 to the left and 57 to the right which lifts link-arm 53 by reason of pin G6 being in cut-out G2 so as to clear it from the stud 33 mounted on the gear frame which is then free to assume its normal position where none of its gears contact with gear 21, when the machine becomes inoperative. This half revolution of the gear wheel 21 has, by connection of the 'pitman 22, swung the yoke G and raised the upperpresser plate F into the position shown by dotted lines. The next succeeding operation will bring the upper presser plate F down into contact with the lower presser plate B and is accomplished as follows: The operator swings the lever 51 to the other locking position, drawing the arm 53 toward him, which engages the pin 33 in @einem notch 54 so that the complete movement of the link by the operator tilts the gear frame to bring gear 37 4into contact with gear 21 which gives the latter gear a half turn in the opposite direction. This half turn frees stud all of `its contact allowingl wheel 58 to be turned to the right so that its notch engages stud 'or pin 6 8. Stud 44: comes to bear on the elbow 112 and again throws out the upper end of arm 41 which correspondingly turns wheel 58 to the left and lifts link 53 as in the other case. This again disengages the gear frame and allows the gear 37 to escape contact with the gear 21. This operation has brought the upper presser F down into contact with the lower presser and applied pressure to the articleplaced on the lower presser or plate.

lt will thus be seen that the construction we have -provided consists in this feature of an automatic stop at each end of the stroke, either upward to lift the swinging plate F or downward to vperform the operation of pressing, and thev adjustment is such that the gears maintain operative contact to their full efliciency until the full completion of the operation and are then instantly. disconnected.

@n the secondary frame or arms Erare mounted brackets 75 in which is journaled a shaft 76' "which has rearward extending arms 77 with studs 78parallel with the I 4shaft 76. On the studs are journaled arms 79 which carry brass plate 8O which 1s to be lowered upon the shirt bosom when it is laid on the felts or other covering of the` lower plate B. The shaft 7G has mounted thereon a. handle 81 and plate 80 has pro jecting handle or lug 82. When the bosom has been laid on the felts, plate 80 is lowered thereon, it being cut-out at 83 with an aperture for the neck-band of the shirt, the collar having been secured by button 84. The handle 81 is'then presseddownward which swings the arms 77 to the farthest traveling circle thereby drawing the curvedV edge of the cut-out or aperture 83 closely against the front portion of the neck-band which is shown' as 85, the edge of the plate being under the collar and close up to the connecting edge between the collar'and the bosom, and thus straightening and flattening the bosom of the garment. The upper presser member F is then brought down upon the plate with' its interior cut-out corresponding to the cut out in the brass plate,

the edge of the cut-out being somewhat removed from the corresponding edge of the brass plate, the cut-out of the presser being indicated in dotted lines in Fig. fi. the edge of the presser F being near enough to transmit the necessary heat to perfect the pressing operation. After the garment has been pressed the handle 8l is lifted again which shoves the plate forward so that its edge tai will clear the collar and collar button when i the plate is lifted out of its position by lifting the handle 82. y

Instead of employing the brass plate 80, which is applicable to bosoms of a single flap or ply, it may be desired to use a plate of smaller dimensions in ironing shirts with double bosom the plate being of a size to overlie only one portion of the bosom or the other.

We show means for applying heat to the upper plate which is hollow, as indicated within the dotted lines shown in Fig. 1, the recess ext-ending through the center of the arm F, to and through the shaft on which the arm is mounted to the journals, the shaft being provided at each end with a bib for the mounting 4of the steam connection. While we show the device as applicable for the use of steam heat, it will be understood that any other suitable heating means can be applied.

Changes, modifications and variations may be made by one skilled in the art, without departing from the spirit and scope of our invention.
