IRONING Application led September To all whom t may 0071 oem:

Be it known that. I, IVENDELL S. MERICK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ironing Machines, of which the following is a specification.

This invention relates to ironing machines.

It will be explained as applied to an ironing machinehaving a motordriven rotatable pressing cylinder and a hea-ted, nonrotatable pressing shoe. The' cylinder and shoe are relatively movable toward and from each other in assuming pressing and non-pressing positions.

With the' ordinary ironing machine the shoe will not burn the padding on the cylinder as long as the cylinder is in motion. However, if for any cause, the cylinder stops while the heated shoe is in Contact therewith, the padding is very apt to burn, resulting in its destruction and the creation' ot a dangerous tire hazard.

-One of the objects oi this invention is to provide an improved ironing machine. i

Another object is to provide an ironing machine wherein the shoe and cylinder are automatically separated whenever the cylinder ceases to turn or appreciably decreases its rate of rotation.

Another object is to provide an ironing machine wherein the shoe and cylinder, when brought together to pressing position, are automatically held in such condition until the rate of rotation oi. the pressing cylinder decreases.

Other objects atter appear.

Fig. 9 is an enlarged view showing the relation ot the trip and latch in locking position.

The ironing machine has a rotatable pressing cylinder land a curved pressing shoe 2.

, The shoe is rigidly connected at opposite ends to end frames 3 and 4,.respectively. The end frames may be made of suitable material such as pressed steel or cast iron. The shoe may be heated by any suitable means.

Cylinder l is carried on a shaft 5 which is journaled, at opposite ends, in brackets 6 and 7. Brackets 6 and 'T are journaled on and supported by a shaft 8 which extends between and is iournaled to end frames 3 and et. The. cylinder is rotated by a motor 9 through a vertical shaft 10 and worm and gear trains11 and 12. The worm and gear trains and shaft 11 are housed in bracket 6. Motor 9 is carried by a pair of brackets 13 and 14 rigidly bolted to shaft 8 so as to be moved therewith. The motor is journaled to brackets 13 and 14 so that it is rotatably mounted as a whole for a purpose to be hereinafter explained.

Thus when shaft 8 is rocked, as will be hereinafter described cylinder l is moved into and out of pressing position relative to shoe 2 and the motor is also rocked so that the driving gear trains remain in proper engagement.

Shaft 8 has an arm 16 secured thereto at each end. Each arm 16 has a socket 17 pivotally attached to its outer end. Each socket 17 has a rod 18 sliilably passing therethrough. Rods 18' are `threaded at their lower ends and slidably pass through sockets 19. Sockets 19 are respectively pivotally carried on one arm of a. pair ot bell crank levers 20. A. pin 21, passing through each rod 18, and cooperating with the corresponding socket 17, anchors one end of the rods. The threaded end of each rod has an adjusting nut 22 thereon which cooperates with the corresponding socket 19 to regulate the eective length of the respective rod.

Bell crank levers 20 are rigidly secured to a shaft 25 which is journaled in end frames 3 and 4 and have a foot rail 26 pivotally connected thereto. Thus t-he depression of rail 26 oscillates bell crank levers 20 and,

. teeth of the ratchet on lever from .the shoe.

The cylinder 1s held in pressing position when it has been moved thereto.

An arm 27 is rigidlyT secured to shaft 25 so as to move therewith. Arm 27 is pivotally connected to a lbell crank lever 28. One

arm of lever 28 is pivotally connected to` the front of. rail 26 by a link 29. The other arm of lever 26 is provided with-ratchet teeth 30. Ratchet teeth 30 cooperate with a latch 3l secured to journaled in end frames Band 4. Latch 3l is a substantially L shaped arm jour-naled ina disc 33 carriedon shaft 32.

Latch 3l is connected to a link SiJwhich is connected to one arm ot a hell crank lever on a shaft 36. Shaft 36 is journaled in end frames 3 and 4. The other arm ol lever is connected to the frame ot motor E) l-. a link 37.

The operation -ot the machine is as tollows:

Depression of rail 26 moves the cylinder into pressing position previously explained. The "rotation vot motor 9 causes the same to move as a whole in the journals of brackets 13 and 14.' This slight movement or torque of the inotor pulls link 37 and rocks bell crank lever 35. The rocking of bell crank lever 35 moves latch 31 so .thatl it is in a position to engage and hold one of the ratchet teeth ot lever 28 (see Thus when the rail is depressed while the motor is rotating;r the cylinder the 28 are engaged and held hy latch f-ll. While vthe motor is running the cylinder ma)v he released and titi' moved from pressing' position hv theoperator slightly tilting' rail 26. This tilting of the rail rocks lever 2Q and its'teeth are disengaged from latch -l'l.-

As long' as the motor is running` with sufiicient speed to create a pulling' i'orce or torque sufficient to rock and hold latch 3l in locking position the cylinder is held in pressing positionluntil released by the operator. i l A However. should the speed ot the motor decrease, because ot interruption ot the circuit .thereto or troniother causes, to a point where its tendency to rotate or its torque will'not create suiticient. pull to..hold latch 3l in lockingr position the latch rocks hac-k' to the position shown in Fig. 8; lever'28 I' shoe, a .rotatable pressing cylinder,

a shaft 32avliich is` ally and consequently the `cylinder speed tails below a predetermined amount.

'Having' described my invention what l claim as new and ters Patent, is

1. An ironingy machinehaving)- a pressing;l means for moving theycy inder and shoe relatiiel'v nearer together to pressing position and holding the same in such condition` and means for causing the separation ot' shoe and cylinder when the 'cylinder rotation decreases. i

2. An ironingmachine having a pressing shoe. and rotatable cylinder which are moved relatively nearertogether to pressii-r;T posidesire to secure by Lettion, means for rotating4 the cylinder. and f meansfor automatically causipg' the separa' tionI of' cylinder and shoe upon a decrease in the rate ot rotation ot' the cylinder.

An ironing machine having' a pressingr shoe and a rotatable cylinder which are Vadapted to lie Inoved relatively nearer together to pressingr position` manually con- A trolled mechanism tor moving the shoe and cylinder relatively nearer together, a latch for locking the mechanism in a position to hold the cylinder and'shoe together. means for rotating` the cylinder, and means under the control of the first mentioned means and latch land acting automatically to release the allow separation of the cylinde and shoe when the speed thereof decreases.. Ll. An ironing machine having a stationary heated shoe,'a rotatable cylinder adapted to he moved into and out ot' pressing relation to the shoe. a motor orrotatng' the cylinder; means for holdingthe cylinder in pressing' position as long as the motor speed is maintained, and means for causing the cylinder to move to nou-pressing position whenever the. motor speed decreases below a predetermined amount.

5. An ironing` machine having a pivoted rotatable cylinder, a relatively stationary shoe, means forrotating` the cylinder. mannactuated mechanism fo1 41no\'in1tlie cylinder into pressing position theshoe, a latch 'for holding the cylinder pressing;4 position,and a release for the latch controlled by thej rate ot rotation ot the` cylinder.
