WILLIAM M. BARNES, OF PHILADELPHIA, PENNSYLVANIA.

IRONING-MACHINE.

SPEGIFICATION forming part of Letters Patent No. 679,718, dated August 6, 1901. Application filed February 19, 1901. Serial No. 47,906. (No model.)

To all whom t may concern:

Be it known that I, WILLIAM M. BARNES, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Ironing- Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to ironing-machines, and particularly to that type of machine wherein one ironing-roller is normally out of operative relation with the other ironingroller and is brought into operative relation therewith by foot power and wherein reversal of the direction of rotation of the rolls while they are in operative relation with each other is also accomplished by foot-power. In machines of this type it is customaryV to have two independent foot-treadles, one connected with the roll-moving mechanism and operated by one foot and the other connected with the reversing mechanism and operated by the other foot. The manipulation of two independent foot-treadles is amatter of considerable difficulty and tends to unduly tire the operator.

The object of my invention is to so connect the roll-moving mechanism and the reversing mechanism together that they may be operated successively from the same foot-treadle.

,Figure l is a front view of the machine. Fig. 2 is an end view, and Fig. 3 is a diagram showing different positions of the operatinglevers for throwing into gear the ironingrollers and for reversing.

A B are the ironing-rollers. The roller A is on a shaft a in fixed bearings in the main frame. The roller B is on a shaft b, having its bearing at the end opposite the 'rollers in a box C, through which extends a bolt c, secured to the main frame. The shaft b is thus pivoted at one end, and normally the roller end of the shaft drops down byits own weight, so that the roller B is out of operative position relatively to the roller A.

A' is a gear on shaft a. B is a gear 011 shaft b. The two gears are thrown into engagement by lifting the shaft b into position to bring the roller B into operative relation with roller A. Any movement of rotation imparted' to the shaft a will therefore produce an equal and opposite rotation of the shaft b, and the article to be ironed is fed between Athe oppositely-rotating rollers A and B.

To drive the shaft a., there is provided the driving-pulley D, fast on the shaft d. The shaft d has the pinion D', engaging gear A2 on shaft o..

To lift the shaft b so as to throw gear B into engagement with gear A', I provide a box E, through which the shaft b extends and which is slidable in vertical guides on the main frame. Engaging one end of the box is one end of a rod F, the other end of the rod being in engagement with the short end of a lever G, pivoted between its ends to the shaft g. By depressing the long end of the lever G, which is shaped to form a foottreadle, the shaft b is elevated and the gear B moved into engagement with gear A'.

To reverse the rollers, so that the article to be ironed may be fed back and forth between the rollers, I provide the following mechanism:

M M' are loose pulleys on the shaft d, one on each side of the fast pulley D.

I-I H are driving-belts driven from any convenient source of power in opposite directions. These belts extend through guides 7i h', respectively secured to a rod I. The rod I is secured to an arm J, which is in turn secured to a rod K. The shaft d is made hollow, and the rod K extends through the shaft, the rod also extending through the main frame and being provided with a collar la.

L is a coiled compression-spring surrounding rod K and confined between the main frame and the collar lc. The collar lo is also shown as bearing against a fixed lug It' on the main frame. By this means the rod K is held normally in such position that the belts are held in the positions shown in Fig. 1, wherein one belt H engages the fast pulleyD and the other belt H the loose pulley M,there by causing the ironing-rollers to rotate in the direction to carry forward the article to be ironed between the rollers.

N is a lever pivoted between its ends to the shaft fn. The long end of the lever N s secured to the rod K, while the short end is `secured to the link O. By pulling the link IOO O to the right the rod K is pushed to the left (the spring L being compressed) and the belts shifted so that belt H engages the loose pulley M and belt H' engages the fast pulley D, the rollers thereupon being driven in the opposite direction to feed backward the article to be ironed.

P is a bell-crank lever, the short end being pivoted to the link O, while the long end forms a foot-treadle P. This bell-crank 1ever is pivoted to the long end of lever G a short distance from its end.

When the machine is not being operated for the purpose of ironing, the belt H is in engagement with pulley D, the shaft a, roller A, and gear A are revolving, andthe shaft b has dropped so that gear B is' disengaged with gear A', and the parts F G N O P P are inthe positions shown in full lines in Fig. 3. The first operation is to lift the shaft b. The operator places his foot upon the foot-treadle P. The front part of the foot will thereby rest over the end of lever G. By throwing the weight of his foot on lever G the said lever is depressed, thereby bringing the leverG and rod F into the position shown in dotted lines in Fig. 3 and lifting the shaft b, moving gear B'Ainto engagement with gear A and causing both rollers to rotate. By depressing lever G no movement of the reversing mechanism is eected; but inasmuch as the bellcrank lever P is moved somewhat farther apwayfrom the lower end of leverN the short end of bell-crank lever P will be moved to the left and the foot-treadle P', While being bodily depressed, will be lifted relatively t0 the lever G to about a horizontal position, as illustrated in the diagram, Fig. 3, and as shown in Fig. l.

During the rotation of the rolls, as just described, to feed the article to be ironed for- Ward sufficient pressure is maintained on`the foot-treadle to hold it in about a horizontal position. To reverse the rotation of the rolls, the entire weight of the foot is thrown on the foot-treadle P', thereby moving it downwardly on its pivotal connection With lever G to the position shown in dotted lines, Fig. 3, drawing the link O to the right, moving lever N from the position shown in full lines to the position shown in dotted lines, Fig. 3, thereby moving the belt H into engagement with pulleyD and the belt H into engagement with pulley M', as before described. The rollers now rotate in the opposite direction, and the article to be ironed is fed backward. The rollers may be again reversed, so as to cause the rollers to feed .the article to be ironed forward by releasing the pressure on foot-treadle P and maintainingthe pressure on lever G. The spring L at once acts to shift the belts to their normal position and returns the foot-treadle P to about ahorizontal position. To stop the machine,

the foot is taken olf the treadle and the parts return to their normal position, the shaft b dropping by its own Weight.

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is-
