Application filed June 11, 1921. Serial No. 478,792.

This invention relates to ironing machines and more particularly to a safety derice for machines of this character.

In ironing machines of the type in whlch B a rotating feeding element or roller cooperates with an ironing element or shoe to feed the material therebetween there is danger that the hands or fingers-of the operator may be fed between the feedingelement and the ironing element thereby 8813101151); 1n uri and crushing these members.

. %lhe object of this invention is to safeguard the operator of an ironing machine by preventing the feeding of the operators fingers or hands between the elements of the machine. Another object of the invention is to provide means accessible from the front of the machine for starting or stopping the machine motor.

Further objects of the invention Wlll appear from the following .specification taken in connection with the drawings, m which,-- Fig. 1 is an end elevation partly in section of an ironing machine having a safety .device constructed in accordance with my invention. r

Fig. 2 isa front elevation of the safety device shown in Fig. 1, and

. .Fig. 3 is a sectional view taken substantially on line 33 of Fig. 2.

Briefly stated the objects of the invention by providing a member such as a rod or bar positioned above the feed roller and between the table and the ironing element, these members'being connected to a switch for controlling the driving motor. The safety device in this instance, therefore, is designed to cut oil the power from the feed roller before the hands or fingers of-the operator can reach the ironing element or are attained in the embodiment illustratedand the feed roller may be utilized and in the embodiment of the invention illustrated these connections comprise a worm 26 carried by the motorshaft and meshing with a worm ear 27 carried by shaft 28, the latter sha being splined to a shaft 29. The shaft 29 is connected through a worm 30 andworm gear 31 to the roller shaft 32.

Thesafety device com rises a rod or bar 33 which extends throughout the length 'of the, roller 23'and is secured at its ends to arms 34 carried by a shaft 35 mounted in the frame members 20. A stop 36 is carried by each of the frame v the backward movement of the arms 34. The shaft 35 has secured thereto an arm 37,

the lower end of which is slotted as shown at 38. A snap'switch 39 is secured to one of the frame-members and -is connected by wires 40 and 41 to the motor 22. .A button or pin42 is carried by the switch 39 and extends into the slotted portion 38 of the arm 37. Any suitab switch may be used and in the embodiment shown the full line position of the button 42 indicates the closed position of the switch. 'When, however, the button is moved to the dotted line position upon the raising of the' bar 33, theswitch will be opened and the motor will be stopped.

From the position of the rod 33 in close proximity to the surface of the feed roller and between the table 21 and the shoe 24. it will be evident that the fingers of an operator would engage and raise this rod before they could pass between the feed roller and the ironing-shoe. The safety device, therefore, effectively prevents the feeding of the operatoris fingers into the-machine.

The rod 33 or arms 34 may be actuated, of course, to start or stop the motor at any time the operator desires and these parts therefore serve the pur ose of control means as well as of a safety evice.

Although one specific embodiment of the invention has been illustrated and described, it will be understood that the invention is capable of modification and that changes in the construction and in the arran ment of the cooperating parts maybe ma e without departing from the spirit or scope of the ilfigention as expressed in the following 0 11118.

members and limits 1e construction of' What I claim is:-

1. In anironing machine, a feeding element, an ironing element, driving means for said feeding element, a safety device positioned in advance of the ironing element and adapted to be engaged and actuated by the fingers of the operator as they rest on and are fed by the feeding element toward the ironing element and control connections between saidsafety device and said driving means, said control connections including an electric switch and positive operative connections between the safety device and switch whereby movement of the device 15 away from the ironing element will open the switch and movement of the device toward the ironing element will close the switch.

2. In an ironing machine, a feed roller, a shoe, a rod above said roller located in advance of the shoe, a motor-operatively connected to drive said feed roll and means in cluding a switch and operative connections between the switch and the rod whereby movement of the rod away from the roller will open the switch and movement of the rod toward the roller will close the switch.

In witness whereof, I have hereunto set my hand this 10th day of June, 1921.
