JOHN, N. GOULD, OF FREDERICKTOWN, OHIO, ASSIGNOB TO THE F. B. ZIEG MAN UFAC- TURING COMPANY, OF FREDERICKTOWN, OHIO, A CORPORATION OF OHIO.

IRONING Application filed September T 0 all whom it may concern:

Be it known that I, JoHN N. GoULD, a

citizen of the United States, residing at Fredericktown, in the county of Knox and State of Ohio, have invented certain new and useful Improvements in Ironing Machines, of' which the following is a specification.

This invention relates to improvements in ironing machines of .a type employing a stationary shoe and a movable roll or cylinder co-operating with the shoe.

The object of the invention is to provide improved means for controlling the roll whereby it may be throwninto or out of operative relation with the shoe.

A further object of my invention is to provide a machine of this character which will be simple in its construction, economical in manufacture and effective in operation.

Referring to the drawings Fig. 1 is a front elevation of a machine embodying the improvements.

Fig. 2 is a side elevation showing the parts in operative position.

Fig. 3 is a side elevation showing the parts in inoperative position.

Fig. 4 is an enlarged side elevation of some of the parts shown in Figs. 2 and 3.

Referring to the drawings 1 represents the supporting legs for a table 2 upon which the operating parts are carried, the legs beingconnected together by the cross rods 2. Secured to each end of the table is a supporting casting 3 having a forwardly and upwardly projecting arm 4. Pivotally connected with each support 3 is a bracket 5 consisting of a vertically arranged arm 5 a horizontal forwardly-extending arm 5 and a forked extension 5 arranged substantially at the juncture of the two arms and projecting upwardly and rearwardly. The lower end of each arm 5 is pivoted on a pin 6 secured to the support 3. Mounted in the forked extension 5 is a shaft 7 of a roll or cylinder 8 and secured to the arms 5 of the brackets is a feed board or table 8. Also secured to the rear portion of the supports 3 is an upwardly extending hollow shoe 9 having a concave face on its forward side which co-operates with the cylinder 8, provisions being made for heating the shoe of any usual character, not shown in the present case. The cylinder 8 is driven from MACHINE.

12, 1921. Serial No. 499,965.

from the short arms of levers 20 through the medium of springs 21, said levers being pivoted on pins carried by the arms 4. Each of these springs is confined between its corresponding lever and a nut 22 threaded on a rod 23 which extends loosely through the lever and has a stop pin 23 in its lower end. The upper end of the rod has a head 24 upon which the bracket 5 rests. The heads are threaded on the respective rodsso as to be adjustable for the purpose of adjusting the relation of the cylinder and shoe, each head being held in its adjusted position by a jamb-nut 25. The tension of the springs may be adjusted by the nut 22. The lower edge of each bracket arm 5* has an inclined surface 26 at. the point where it .rests upon the head and also has a. stop 27 at the rear end of this inclined surface and a recess 28 at the forward end thereof, one wall 29 of which is extended and inclined downwardly.

The arms of the levers 20'are connected by links 30 with the arms 31 of a pair of bell crank levers which are pivoted upon one of the lower rods 2*. The arms 31 of these bell crank levers are connected together by a rod 32, while the arms 34 of the levers are connected together by the rod 33.

In operation, the roll or cylinder 8 is thrown onto operative relation with the shoe 9 by pressing with the foot upon the rod 32 which throws the parts to the position shown-in Fig. 2, which places the springs 21 under tension, the springs 21 yielding under pressure to accommodate different thicknesses of material fed between the roll and shoe. When the parts are in this position, it will be observed that the points of contact between the brackets 5 and the headsof short arms of the levers in very close proximity to the fulcrum pins 4*, results in practice in causing the levers to act as fixed abutments for the springs to sustain the roll in operative posit-ion against the shoe, the springs only yielding under pressure of the roll to accommodate difierent thicknesses of material. By pressing upon the rod 33, and swinging the arms 31 of the bell crank levers upwardly, the long arms of the levers 20 will be elevated and the short arms thereof depressed thus swinging the spring supports forwardly and downwardly permitting the table and cylinder to rotate forwardly upon the pivot pins 6 by gravity,

thus separating the cylinder and shoe. The

recesses 28 will receive the heads 24 and act to retain the partsin this posit-ion, the ex treme outer end ofthe recess being formed with a stop 29.

Having thus described my invention, I claim 1. In a machine of the character described, a stationarily supported member, a pivoted cylinder movable to and from said member upon the arc of a circle, a feed table so supported as to be movab-lewith said cylinder, a resilient support below said table upon which the table is adapted to rest to support said table and cylinder, and means for swinging said support relatively tosaid table whereby said table and cylinder may be resiliently held in Working position or permitted to swing by gravity to inoperative position, said support being capable of yielding independently of said swinging means.

2. In a machine of the character described, astationary shoe, a pair of pivoted brackets, a cylinder journaled in said brackets, a. feed table supported by said brackets, resilient supports for said brackets for supporting the cylinder and table in working relation with said shoe, and means for moving said supports from supporting position to permit the table and cylinder to swing by gravity away from said shoe.

3. In a machine of the character described, a stationary shoe, a cylinder movable t0 and from said shoe supported at a point removed from said shoe, a pivoted lever, a resilient support for said cylinder carried by one arm of said lever, and devices connected with the other arm of said lever whereby said resilient support may be moved from silient support carried by one arm of said" lever for said table'and cylinder, and means connected with the other arm of said lever for swinging said support to permit said ta I ble and cylinder to move by gravity away from said shoe.

5. In a machine of the character described, a stationary shoe, a pair of pivoted brack-- ets, a cylinder journaled in said brackets,.a table supported by said brackets, a pivoted lever, a resilient support on one arm of said lever, and foot operated devices connected with the other arm of said lever whereby said support may be moved tohold said cylinder and table in' working relation with said shoe or permitted to fall away from said shoe by gravity.

6. In a machine of the character described, a stationary shoe, a pivoted cylinder and feed table, a resilient support for said cylinder and table, a pivoted lever to one arm of which said support is connected, a bell crank lever, a connection between one arm of said bell crank lever and said supporting lever, and foot rests connected .With the respective arms of said bell crank lever for swinging said resilient support to cause it to support said table and cylinder in working relation with said shoe or permit the tab-1e and cylinder to swing away from said shoe by gravity.

7. In a machine of the character described, a stationary shoe, a pivoted bracket, a cylinder journa-led in said bracket, 21- pivoted lever, a rod slidably mounted in said lever in close proximity to the fulcrum point thereof, and a spring yieldably sustaining said rod, said rod forming a support for said bracket with the point of support located in substantial vertical alignment with the fulcrum of said lever when said rod is in suppo-rting'position, and means for rocking said lever.

In testmony whereof, I have hereunto set my hand this. 6th day of September 1921.

JOHN N. GOULD.
