SPECIFICATION forming part of Lettersjlatent No. 513,687, dated January 30, 1894.

Application filed. January 8, 1 8 92 To all whom it may concern.-

Be it known that I, ARTHUR R. SELDEN, a' citizen of the United States, and a resident of the city of Rochester, in the county of 'Monroe and State of New York, have invented certain new and. useful Improvements in Ironing-Machines, of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 is a front elevation of my machine. Fig. 2 is a plan view thereof. Fig. 3 is ahorizontal cross section on the line w-ag of Fig. 1 of the devices for reversing the motion of the roller. Fig. 4-is an end elevation of the ratchet ring of the clutch. Fig. 5 is a side elevation of said ring. Fig. 6is an end elevation of .the whole machine. Fig. 7 is an enlarged top plan view of the treadle of the machine. Fig. 8 is an enlarged front elevation of .said treadle. Fig. 9 is a detailed view of the lever, yoke and segments to operate the clutch.

My invention relates to improvements in ironing machines in which a revolving roller,

preferably padded, is used to support the goods and a smooth heated metallic surface is caused to press the goods against the roller.

The object of my invention is to "simplify the machinery necessary for this purpose and to provide a more effective and durable machine.

My invention consists in the devices and combinations of mechanism hereinafter described and claimed.

A is the frame of my ironing machine which is made of any suitable form or dimensions. I prefer, however, tofmake it of the three parts shown inthe drawings, viz: the main frame piece shown at the upper part of Fig."

1, and the two pairs of legs shown in the fig-. nres. At suitable points on the frame I place journal boxes I) bin which revolves the shaft B which carries on one end the roller 0. Within the frame and between the journal boxes upon this shaft I place a pair of bevel gears, D, D, preferably large. These mesh with the small bevel pinion E which is propelled by the driving pulley F.

Upon the shaft B, and between the two.

bevel gears D D, is a clutch ring G, upon the two faces of which are cut ratchet teeth, substantially as shownin Figsi i and 5, which teeth mesh with similar teeth out on the faces Serial No. 417,373. (No model.)

of the two gear wheels D D, according as the ring G is moved along the shaftB to one side or the other. The ring is splined to the shaft by means of the key g'but is capable, as stated,

of longitudinal motion along the line of the spline. The two large bevel gears D D are loose upon the shaft 13. The driving pulley F revolves continuously in one direction and through the medium of the small bevel pinion E, causes the large bevel gears D D to revolve continuously in opposite directions. These, as above stated, are loose upon the shaft B, but the ring Gbeing splined to the shaft, and capable of longitudinal motion thereon, will communicate motion to the shaft B in one direction or the other according as the teeth of the ring G mesh with the teeth on one or the other of the wheelsD D. In a suitable position on the frame of the machine is pivoted as by the cross shaft h a lever H which has a yoke upon one end. From the ends h h of this yoke, segments of a ring 71 4, preferably pivoted to the yoke extend into a groove f around the ring G. The lever His connected with a treadle as hereinafter described, by means of which motion is imparted through the. vibrating lever H, the ends it h of the yoke and the segments 1' i to the ring G, which brings the clutch into operation so as to produce motion of the roller 0 in one di J' which forms an axis in .a .planeat right angles tothe axis of the roller-C. The rod j is revolubly fixed in the sleeveJ': by means of collars j j or other suitable devices. The sleeve J is pivoted to the frame by a transverse pivot J whose axis crosses the axis of the armj at right angles and is parallel with the axis of the roller 0 or approximately so. Thus'a kind of universal joint is formed in which the' iron may oscillate in a plane to hich thebar or 'arm j is perpendicular, as

the bar or arm j is axially revoluble in the.

sleeve jJ and the iron oscillates to and from the roller about thetransverse pivot J, but

cannot oscillate endwise or otherwise than to and from the roller.

On the bar j at a suitable point is fixed a counter -weight J" to counterbalance the weight of the iron K. The iron K has a pol ished surface, preferably concave, next to the roller and substantially concentric therewith. On the upper side of the iron K is a pair of tracks k k and to a projection a of the frame A are fastened adj ustably stops 70' k to limit the motion of the iron K from the roller 0.

To the extension at of the frame A are pivoted a pair of cams or hell cranks L L. These also are adjustable, preferably at the points of connection with the frame A. These bell cranks bear wheels or rollers ll adapted to roll upon the tracks 7c of the iron K. The cams or hell crank levers L L are also connected by the long arm Z to a treadle M, and, according as the treadle is raised or depressed, the motion of the bell cranks will cause the counter-balanced iron K to approach the roller 0 or to recede from it in a curve or plane passing through the roller. The stops 7c are so adjusted that the outer end of the iron K is allowed to move-farther away from the roller C, than the inner end thereof. See Figs. 1, 2 and 6. Thus the goods to be ironed may he slipped the more easily upon the roller when the iron is raised.

In order that the treadle M may operate equally and"evenly upon the bell cranks L L and may produce an even pressure of the iron K upon the whole length of the roller (1,1 provide an equalizing bar N from each end of which a rod it extends to the long arm Z of the bell crank levers L L. From the middle of the equalizing bar N extends a rod 01/ to the treadle M. This rod is loosely fastened to the equalizing bar so that free oscillation of the equalizing bar is permitted. By these devices I produce an even pressure of the iron K against the roller 0 and also if the goods passing between the roller and the iron are uneven in thickness, the iron K adj ustsitself to the inequalities and conforms its position to inequalities under the same.

The treadle M is provided with an upright O pivoted horizontally to it by the bar 0, passing through the bearings 0 0'. The end of this barb is fastened to a foot piece P by means of the upright portion 1).

Upon the frame of the treadle M are formed two extensions or lugs m m and upon the vertical portion 19, are formed two stops 1) p. The stops 1) and the lugs m limit the motion of the foot piece P which through the bar 0 causes the upright O to oscillate in a plane vertical or nearly so. The upper portion of this upright O is pivoted to the bar h" which is connected to the pivoted lever H. According as one or the other side of the foot piece P is depressed, the lever 0 (when the treadle is depressed) will oscillate from one side to the other, will communicate movement to the lever H, which will,as above described, operate the ring or clutch G and cause motion of revolution,in one direction or the other, to be imparted to the roller 0. The lever M 1s pivoted to the frame of the machine by a 11011- zontal pivot m. The bevel gears D D are so placed on the shaft B that neither of them will be in engagement with the clutch G, 1f the same is located exactly between the two.

In order to guide the ring G to the exact middle point I provide a guide Q wh ch has sides narrowing upwardly and which 1s fixed rigidly to the frame of the device in such a position that when the treadle is allowed to rise, the end of the upright O enters between the flaring sides of the guide Q and in rlsing is guided into such aposition that the clutch G will, through the lever II and the bar 72/, be guided exactly to the center. I make the sides of said guide Q sulficiently wide apart below to receive the end of the upright O at any position which the parts may assume when the treadle M rises, and of such a wldth apart above that the upright O is exactly guided into place. See Fig. l.

Springs as R R, are provided to lift the treadle and move the connected parts out of operation.

Stops s s are fixed upon the tracks 70 7a to limit the motion of the cams or bell cranks L L.
