SPECIFICATION `forming part of Letters Patent No. 542,233, dated July 9, 1895.

Application filed January 17, 1895. Serial No. 535,294. (No model.)

chines of that class designed for ironing the bosoms of shirts and in which `an ir'on is caused to traverse a table or board; and it relates more particularly to the construction and arrangement of parts of such a machine.

The principal objects of my invention are,

first, to provide an ironing-machine which shall be comparatively simple, durable, and efficient in action, and, second, to provide an ironing-machine having parts thereof, as well as the actions or operations of said parts, simpliiied, so as to readily permit the introduction or removal of an article to be ironed, and to insure thorough treatment of the article by the iron in action.

My invention consists of an ironing-machine constructed and arranged as hereinafter more fully described, andv pointed out in the claims. Y

The nature, characteristic features, and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, in which- Figure 1 is a side elevational view of an ironing-machine embodying features of my invention. Fig. 2 is a rear elevation thereof. Fig. 3 is an enlarged top plan and central section of one form of a fluid-check embodying features of my invention. Fig. 4 is a top or plan view of the machine. Fig. 5 is a side elevation of a modified form of check for use in an ironingmachine for checking the retrograde movement of parts of the machine and thereby reducing shock or jar on such parts to a minimum. Fig. 6 is an enlarged longitudinal section of one of the friction-rolls of the machine. Fig. 7 is an enlarged side elevation, partly in broken section, showing` in detail the oil-collecting device disposed-between the traveler-iron and its bearings for preventing spread o f oil onto the working-surface of the iron in action. Fig. 8 is an end view of Fig.

6 with the nntp*V removed, and Fig. 9 is a scction on the line an a; of Fig. 7.

Referring to the drawings, a is the main frame ot' the machine. l

b is the frame of the traveler revoluble iron c. VThis frame b is pivoted, as at d, to the main frame a, and the iron c has its hollow interior supplied with air and gas, steam, other or heat through the pipe c.

The main or driving-shaft e, is journaled in the main-frame a, and is provided at one end with tight and loos'epulleys e and e2, and at the other end witha pulley e3. This pulley7 e3 is connected by a belt e4, passing around a `pulley d2, loosely mounted on a shaft CZ, with a pulley c2, secnredvto the shaft c3, of the revoluble iron c. Through this connection the iron `c is rotated, when the shaft e has motion imparted thereto from any suitable source of power. The tension on the belt e4 is regulated by the lever e5, carrying the tension-roll e6 and weight e7, and pivoted, as at es, to the main-frame a, as clearly illustrated in Fig. 1. This tension device compensates for the motion imparted to the iron c and its pulley c2 by the movement of the frame b, and serves to keep the belt e4 taut, no matter what may be the position of the said frame b. The mainshaft e imparts motion to the counter-shaftf through suitable gear-Wheels f andjz. This shaft f is provided with friction-rolls f3, of peculiar construction, which are normally out of engagement with the roller arms or boards f4, but adapted to advance the arms f4, pivotally connected with the frame b of the iron c, when the arms f4 are brought into close contact with the friction-rolls f3, to be hereinafter more fully explained.

The ironing-table g is preferably provided with a foot g', fitting a recess g2, of a forked downwardly-curved arm g4, the fork g? of which arm is pivoted to ashaft 96. The table gis adapted to be vertically raised or lowered in its bed g3 by means of the following mechanism: At the forward and rear ends of the bed g3, and extending through the arm g4, are the adjusting-screws Q7, each ot' which is provided below the iioor of the bed g3 with a pulley g8. These pulleys are united with each other by a belt gg. One or both of the pulleys g8 may be provided with a lever glo, by means of which the screws g'I may be secured farther into or retracted from their position in the plate g4, and thus a corresponding rotary motion given to the respective pulleys g8, through the belt gg, and the screws to raise or lower the table or board g from its seat in the recessed plate g4. A tension-roll gn, depending from a ratchet or otherwise controlled arm Q12, pivoted or secured to the arm g4, serves to take up slack in the belt gg, and the ends of the screws g7 bear against the base of the foot or support g', and thus elevate the table or board g and its support g', to bring the table closer to or farther from the traveler-iron c, to increase or decrease the bearing friction of one onto the other. The arm g4 is provided with upwardly-extending parallel vertical projections Q13, into which the foot or supportg of the table fits to lock the table against lateral movement in its bed g3.

The board g may be raised or lowered through its end pivotal connections with the shaft g6 by means of the rod 7L, pivoted at h to the outer end of the arm g4. This rod his raised or lowered by the arm 71.2, pivoted thereto and connected with a treadle h3, as clearly illustrated in Fig. l of the drawings.

It is obvious that in place of belts and pulleys, as hereinbefore explained and illustrated in the drawings, chains and sprocket- ;vheels, if preferred, may be substituted there- Adjustably secured in slotted bearingsj of each fork g5 of the arm g4, and carried thereby, are rolls j, on which the roller arms or boards f4 rest. The adjustment of the bearings j of the rolls j in said slots is eected by means of the set screws 3'2, as illustrated in Fig. 1. Upon the shaft g6 is secured, by a screw 7c', the collar 7a2, having two arms or lugs 7c3 and kt. Pivoted to one arm 7c3 is a lever h5, carrying at its forward end the neckband-clamp 706, and at the other end 7i;7 it is normally held in a raised position by means of a helical or coiled spring ks. The other arm 704 of said collar 7a2 is pivoted to a lever 7c", the forward end of which carries the yokeclamp 7610, and the rear end is held in an elevated position by means of the coiled or spiral spring 7c, as illustrated in Figs. l. and 4.

To the yoke-clamp end 71:10 of the lever 7d is pivotally secured the upper end of a rod or arm Z, which is pivotally attached at its lower end to a treadle-arm l', and provided at its upper end with the rounded projection Z2, resting normally under the neckband-clamp k6 of the lever 705.

The frame b of the traveling iron is advanced to traverse the ironing-table g against the retracting force of the springs m, mounted in hollow casings m', which are pivotally connected, as at m2, to the frame b of the iron c by means of the rods m3. The casings m' are pivoted, as at m4, at or about their center, to the main frame a, as illustrated in Figs. l and 2, and have a slight oscillatory movement on said pivots or trunnions m4 when the frame b is advanced or retracted. The retracting force of these'springs m on the frame b is checked by means of the following mechanism, of which two modifications are shown.

In Figs. 1, 2, 3, and 4 the mechanism consists of acylinder fn, pivoted, as at n', to brackets n.2, secured to the main frame a, in the manner fully illustrated in Fig. 1. The cylinder 'n has a cap n3, packing-box n, and funnel a5, and these instrumentalities are traversed by a piston n, the rod nl' of which is pivotally connected to the iron frame b, as at ots. The piston-head n may be provided with an oblique orifice or vent ng, for a purpose to be hereinafter fully explained. With reference to Fig. 3, it will be observed that in this check, in which oil or thick liquid is used and the piston-rod 'n.7 is connected directly with the oscillating frame b, the interior wall of said cylinder is riiied-that is to say, provided with spiral channels n10, extending from the top to a point some distance above the bottom of the cylinder n. The oil or heavy fluid escapes, during part of the downward stroke of the plunger or piston n, through the channels n10, and the oil thereby oers a certain resistance to the plunger and its rod during the first part of the return movement of the frame b under the retracting force of the springs m. W'hen, however, the piston or plunger n has traversed the lower endof the channels nl, the oil escapes through the orifice a9 to afford an increased resistance of thc piston and its rod to the frame b at or near the end of its return stroke, thereby appreciably lessening jar or shock on the working parts of the machine.

The vent n is drilled through the piston n obliquely-that is to say, in a line from the center of the piston toward the Wall of the cylinder n-or so that the oil sporting ont of this vent orifice is thrown against the wall of the cylinder obliquely and not upward against the cap, as would be the case if the orifice was vertically arranged.

With reference to Fig. 5, in which a modiication of the check is shown, it will be seen that the piston-rod 'a7 is pivoted at its upper end to an arm o', projecting from a Spanner or buffer o, one end of which Spanner or buffer is loosely pivoted to a shaft d, forming the pivot of the iron frame b, and the upper end o2 of said buer abuts against the iron frame b. The arm o is held upward normally by a coiled or spiral spring o3. In this form of IOO IIO

check the interior wall of the cylindern is preferably not rfled, as a vent in the pistonhead n will afford sufficient opening for the passage of the oil above and below the same in the working of the same within the cylinder ln. It may, however, be here remarked that the cylinder, as illustrated in Figs. l, 2, 4, and may be internally ritled, as illustrated in Fig. 3, if so desired. When the frame b moves forward in its initial stroke against the force of the springs m, the arm o', of the spanner or buffer o, is caused to move therewith, by means of the spring o3, and carry the piston-rod fn? therewith, and hence the piston to the upper end of the cylinder n, and during such movement the cylinder n will oscillate in the bearings n thereof. -The Spanner or buffer will also be moved forward on the shaft d, with its abutting arm 02 projected forward in the path of the frame b. When the iron frame b returns in the direction offits usual position under the influence of the springs m, it strikes against the abutting arm o2, which is thrown back against the force of the spiral or coiled spring o3, and the projecting arm o of the spanner or buffer supported by said spring is depressed gradually, thereby moving the piston ne, bymeans of its rod nl, downward in the cylinder n. lThe iron frame b thus has a gradual check through the buffer, its spring,`and the oil-check and piston The friction-rolls f3 on the shaft fare preferably constructed as illustrated in Fig. 6. The shaft f is provided with a collar' or vboss p, secured by a screw p to the shaft f and rotating therewith. The bossp is provided with a feather or key p2. The friction-surface of the roll is built up of superposed disks or washers p3, of leather, wood, hard rubber, or other suitable material, which disks A are slipped onto the collar or boss p, being provided with a central opening and keyway for that purpose. After a sufficient number of these washers or disks have been slipped onto the boss, they are compressed together to the required extent by screwing down a nut 104 onA other absorbent material c7.

the boss p, in order to provide an efficient or reliable bearing-surface, as practice has fully demonstrated. turning, screws or pinsp extend through the nut into certain of the disks, thereby securely fastening the nut to the disks and preventing any turning separately of the nut from the disks in position. The screws shown in dotted lines in Fig. 6. The bearing- .svurface ofthe disks may be trimmed by a lathe or in any preferred manner. To change .the friction-surface of the rolls-as, for in-` stance, when the same is worn down too closethe nut is taken olf and the old disks removed and new ones readily'substituted.

The device for preventing the transmission or leakage of oil from the bearing c4 to the working-surface of the iron c is illustratedin detail in Figs. 7 and 9 of the drawings. Between the bearing c4 and the end c6 of the revoluble iron c is wrapped felt, linen, or This wrapping is held from moving laterally by grooving the end c6, as illustrated by the dotted lines at cS in Fig. 7, and a rotary motion is prevented by securing on either side of the bearing c4 a plate or lug C10, around which the wrapping c7 is wound. Any oil escaping from the bearing c4 is absorbed by the linen or felt wrapping, and when the same becomes saturated with oil, such may be removed and a new material readily substituted therefor.

The mode of operation of the hereinbeforedescribed ironing-machine is as followsz'4 The tating.

To prevent the nut p4 from or pins p5 are table gin its normal position is depressed and the iron frame b is at its eXtreme right-hand movement, or clear of the table. The neckband and 'yoke-clamps rest on the end of the table nearest the revolubleiron. Thetreadle ZY is now depressed, lifting the clamps k6 and klo from `the-board g. The shirt is then slipped on in its rightr position, the treadle Z released, and the clamps k6 and klo firmly press the neckband and yoke of the shirt to the table under the tension of the vertical coiled or helical springs ks and Zou. The treadle h3 is now depressed, elevating the table g into operative position-that is, in the path of the revoluble iron c. The forked arms g5 of the support g4 of the table g are thereby raised, carrying with them the rollsj, which elevate the roller boards or alims f4 into frictional contact with the rollers f3, which, being secured to the counter-shaftf, are constantly ro- The boards or arms f4 are pushed from right to left by said rollers f3, moving the frame b and the revoluole iron in an outward direction, whereby the iron c will travi erse the bosom of the shirt or other article.

The springs m retract the frame b when the table is lowered through releasing the foot from the treadle h3; The return movement of the frame b is checked by the mechanism, as hereinbefore fully explained, so that it reaches its normal position without jar or shock 0r undue strain upon the several working parts of the machine. When the shirt or other article is to be removed from the board or table, the treadle Z is depressed by the foot,' whereby the clamps k6 and klo will be raised i out of contact with the table or board'g, and

the machine then brought into a condition for a similar ironing operation of an article.

It will be manifestly obvious that, as to details,'modilications may be made in many of the parts constituting features of my invention and still be within the scope of my invention; and hence I do not wish to be understood as limiting myself to the exact details of construction-and arrangement of all the parts as illustrated but,
