PETER JONESKU, OF CHICAGO, ILLINOIS.

IRONING AND PRESSING MACHINE.

Specification of Application led August 13 To all whom 'it concern:

- Be it known that I` vPinna JoNnsKU, a subject of King Carl of Roumanie, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and 'useful Improvements in Ironing and Pressing Machines, of which the following is a specification. r

My invention relates to' an improvement in ironing and pressing machines, but more particularly to the mechanism employed for moving the swinging iron into pressing engagement with the buck.

The principal object of my invention com prehends the production of a device of the above character, in which the mechanism above referred to, is actuated to bring the pressure and when so actuated, the mechanism will lock, to keep the pressure on the iron uniform; and which will also automatically return to normal position when the pressure'is released.

tages will become apparent as the nature of my invention becomes better understood from the following description and accompanying drawing, 1n Which Figure 1 is a transverse sectional view showing the parts in normal position, and. illustrating by dotted lines, the position of the parts 1n operative position. Fig. 2 is a horizontal sectional view takenon the line 3 3 of Fig. 1, looking down. Fig. 3 is a, detail of the burner for the buck.

Reference being had to the drawing and the numerals indlcated thereon,-1 indicates the table of the machine, which comprises a and an intermediate leg'.

Mounted longitudinally upon the table there is shown a buck. 6 comprising a hollow body having depending legs 7. A -gas burner 8 is disposed within the buckl 6 and receives fuel through a pipe 9, which is provided with a suitable valve 10.

The movable standard of the machine is indicated at 11. The standard 11 is located intermediate leg 5 and is pivotally connected at its lower end to the said intermediate leg 5, by means of spaced links 12,

13. Pivotally connected to the standard 11,' near its lower end, arethe lower ends of L etterslatent- Patented 0ct. 25, 1911). 1910. serial No. 576,984

per ends of which is mounted a roller 15. livotally mounted on the arms 14, near 16. the inner ends of which are pivotally connected to the front end of a piston rod 17. The piston rod 17 is slidably' mounted in a bracket 18 fixed to the leg 5 and has its inner end provided with a piston head 19 which works in a cylinder 19a lixed tothe under side of the table 1 by meansI of brackets 20.

rearwardly of the leg 5 is a casting 21l which is formed with downwardly extending lugs per ends of links 23.. The lower endsof the links 23 are pivotally connected to the ends ofV a member 24. This member 24: is provided with a longitudinal slot' 24 in which the roller 15 of the operating' 'arms .14 is adapted to travel, as will be hereinafter described.- As shownmost clearly. in Fi 1 the rear ends of the lugs 22 extend be ow the pivot point of the links 23 and wido ened as at 25 to form stops. The front ends of the lugs 22-also extend below the. pivot widened extremities to form stops 26. vIt will thus be seen that the swingm movement of the links 23 is limited by t e stops 25 and 26, that is, when the parts are 1n normal position the' links 23 will engage the stops 26, and when in operative ositi'on they will engage the stops 25. A coi spring A, fastened at one end to the front to normal position, as will be hereinafter described.

perend thereof cut awa .to form aiboss 27 through which, and simi ar bosses 28 formed `on the inner end of a horizontally swini arm 29, is passed a vertical-pinO w has its lower end screweduinto the standard bosses 28 of the arm 29 is a sprin 31the purpose of which is to cushion t e shock operative, or pressing position. The arm29 has adjustably mounted. thereon a member spaced operating arms 14e, between the up- '34, the lower endv of which is rotatably REISSUED Mounted on the under sidevof thetable'lv end of the. member 24 and at itsv other end to a. suitable bracket A fixed to the under side' of the table, serves to return the member 24.,

on the arm 29 when the same is brought -to- 3,2 having at its outerend a T-coupling 33 in which is mounted the adjusting screwv their upper ends, are the outer ends of links 22, to Iwhich are pivotally connected the uppoint of the links 28 and are formed with The standard 11 has a portion at the up- 1 --loo ng ich 11. -Coiled about the pin 30 between the boss 27 of the standard and the lower of the mounted on an iron 35, which may be of any desired type of structure. I

At its front end, the cylinder 19El has connee'ted therewith an air receiving pipe 36, receiving air from a suitable reservoir 37. The pipe is provided with a three-way valve 38, one port of which forming communica- In operation, clothes or the like to be y pressed are placed upon the buck and the foot pedal moved down to operate the valve to allow air from the reservoir to enter the cylinder and force the piston forwardly. When this occurs the operating arms 14 will be caused to swing forwardly, its roller 15 'working along the slot 25 of the member 24 and. as the member 24 cannot move upwardly owing to the links 23 engaging the stops 26, this action of the operating arms 14 will cause the standard to move downwardly. lVhen the roller 15 reaches the rear end of the slot 25, the continued forward movement of the piston rod will cause the links 23, together with the member 24, to swing rearwardly until the links 23 engage the stops 25. This will cause the standard to be moved downwardly the balance of its distance, or until the iron 35 bears -upon 'the clothes on the buck. The desired pressure may be attained by adjustingthe screw 34. As shown in dotted lines in Fig. l, when the links 23 engage the vstops 25 they will be slightly beyond the dead center, thereby causing said links to lock and keep a steady pressure on the iron, As long as air remains in the cylinder 191 the parts will remain in operative position, and the arm 29 may be swung in a horizontal plane to move the iron over the clothes. lVhen it is desired to release the iron from the buck, the valve is turned to close communication between the reservoir and cylinder and to permit air to be discharged through the exhaust pipe 39. When this occurs, the spring A will draw the member 24 forwardly, and as soon as the links 23 pass the dead center, the large springs B act to restore parts to their normal position.

From the foregoing it will be seen that I `providean ironing and pressing machine having only a few operative parts, which will be strong and durable, and which will admirably serve the purpose for which it is intended.

I claim:

In an ironing machine, the combination with a table, of a vertically movable standard, having means to carry the iron, links connecting the standard and the table, a casting secured to the under side of the table, links pivoted at their upper ends to said casting, and a slotted member carried by said links, spaced operating arms pivoted at their lower ends to the lower end of said standard, and a roller journaled between the upper ends of said arms, and

adapted to work in the slot of the aforesaid member, and means for moving the operat ing arms rearwardly to swing the links to a perpendicular position and lower the standard, stops formed on the aforesaid casting, to limit the movement of the links in both directions, certain of said stops being so arranged as to allow the links to swing slightly beyond the dead center when they are moved to perpendicular, to lock the same, and means for returning the parts to normal position.

In testimony whereof I afix my signature in presence of two witnesses.

PETER J ONESKU.
