Serial No. 847,120.

A table 28 is provided for supporting the articles to be ironed, and is mounted for oscillation beneath the ironing roller 25. As shown this ironing table is of curved form and is carried by a pair of supporting rollers 29, 30. A gear-rack 31 extends along the under face of the ironing table for substantially its entire length, and is en aged by a driving gear 32, preferably coaXia 1y mounted with the supporting rollers 29, 30. The movementof the ironing table is guided by a pivoted arm 33, which as shown, comprises two substantially vertical members connected by a cross-member 171 (Fig. 3) and is rotatably'connected to the inner end of the table by means of a pin 34 passing through the arm 33 and engaging ears 28 (Fig. 7) formed integral with the table.

Provision is made for raising and lowering the ironing table for the purpose of adjusting the pressure employed in ironing and for moving the ironing table into and out of operative position. 'To' accommodate these movements of the ironing table, the supporting rollers 29, 30, and the driving gear 32 are shiftably mounted, being, as shown, carried by a shaft 35, which is journaled in a vertically oscillatable frame 36, most clearly illustrated in Figs. 2 and 5. The frame 36 is pivotally attached to the body of the machine at 37, 38, and one of its pivots, as 37, is preferably in the form of a shaft for communicating power to the shaft 35, to which the driving gear 32 is fixed by a key 35 (Fig. 6). The outer end of the frame 36 is carried by a rod 39, rendered adjustable in length by means of a ball nut 40 having a threaded engagement with the upper end of the rod and entering a socket 42 formed in the frame 36. The ball nut 40 carries a pin 43 extending into a groove of the socket for preventing rotation of the nut, and rotation of the rod in the ball nut is normally revented by means of alock nut 41. The ower end of the rod 39 loosely engages a saddle 44, which, as shown, is carried by a shaft 45 extending transversely of the machine near its base and preferably, also, forms the pivotal support for the guiding arm 33. A spring 46, coiled about the end of the rod 39,-reacts between the saddle 44 and a flange 47 formed on the rod to provide a yielding support for the oscillatable frame 36, and a pair of screwbolts 47* loosely engage the flange 47 and the saddle 44 to limit the movement of the rod 89 in the saddle. Preferably a hand wheel 48 is formed on the rod 39, and the pressure for ironing obtained by means of the spring 46 is readily adjusted by turning i the rod in the ball nut after loosening the lock nut 41.

For raising and lowering the ironing table into and out of engagement with the ironing tool, provision is made for vertically shifting the shaft 45, which, as previously de scribed, supports both the saddle 44 and the guiding arm 33. To this end the shaft 45 is carried by links 49, (Fig. 4), rotatably mounted on a shaft 51 extending across the front of the machine and journaled in the upright frame members 15, 16, and a crank shaft 52 is provided for swinging the links. This shaft is preferably journaled at the front of the machine in lugs 53, 54, formed on the horizontal frame member 18, and carries a hand lever 55, having a spring pawl mechanism 56 of ordinary con; struction and adapted to play over a toothed quadrant 57, which, as shown, is rigidly secured to the frame of the machine at 58 (Fig. 1). The cranks of the shaft 52 are connected to the links 49, 50, at the base of the machine by means of rods 59, 60, and these rods are rendered-adjustable in length for the purpose of securing a correct alinement of the parts by means of turn buckles 61.

The ironing table 28 preferably comprises an anvil 62 (Fig. 6) forming the under portion 'of the table, and an ironing plate 63 having an ironing surface covered with padding 67. Apertured lugs 65, 66, which register when the parts are assembled, are

- formed on the anvil 62 and on the ironing formed on the anvil 62,

plate 63, respectively, for receiving a connecting pin 64. The padding 67 is secured in position by a frame 68 fitting over the margins of the plate and pivotally secured thereto adjacent one of its ends, as shown at 69.

The ironing table 28 is preferably provided with a neckband holder 17 0 for engaging the neck-band of the garment to be ironed, and a cavity 71 is formed in the ironing roller for receiving the neckband holder, the wall of the cavity 71 having, shown, an overhanging lip 72 (Fig. 9), which cooperates with the rim of the holder to shape the neckband of the garment and adjacent portion of the bosom. Preferably the neckband holder 170 is made sectional and is yieldingly expanded within the neckband of the garment to secure it in place for ironing. As shown it comprises a fixed and a movable section, designated and 73, respectively, the former taking the form of a ange cured to and projecting in; ironing plate 63, and the i by rods 74 slidably moui about each of the rods 74, reacts between one of the lugs 75 of the anvil and a stop 78 carried by the rod about which it is coiled, for normally separating the two parts of the holder. A cross-head 79 connects the rods 74 at their forward ends, and is engaged by a cam stud 7 9 carried by the crank arm 80 of a crank shaft 8]. journaled in the anvil 62 to advance the rods 74 and the movable section 73 of the neckband holder. The crank shaft 81 is provided with an operating handle 82, conveniently located at one side of the ironing plate. The flange 70 is notched, as indicated at 83, Fig. 9, to receive the shank of a button .1: placed in the front of the neckband 3 of a garment Z, and a clip 84, having its outer end bifurcated, as indicated at 85, to straddle the shank of the collar button to secure it in place within the notch, is pivotally attached to the ironing plate 63 within the flange 70 at 86.

A clamp is provided for gripping the skirt of the garment Z to stretch it over the ironing board. As shown, this comprises apair of clamping jaws 87, 88, supported in a transverse position at the outer end of the ironing plate 63 by rods 89, 90, each slidably engaging ears 91, 92, projecting laterally from the anvil 62. A spring 93 is coiled about each of the rods 89, 90, and reacts between one of the ears, as 92 of the anvil, and" a stop 94 carried by the rod about which it is. coiled to advance the clamping jaws. One of the jaws, as 88, is slidably mounted on the rods 89 and 90, and is, yieldingly advanced upon the other jaw 87, which is fixed in position upon the rods, by springs 95, 96, each coiled about one of the rods and react- 'ing between the rear face of the movable clamping jaw and a stop 97, 98, carried by the rod. A cam shaft 99, journaled in the anvil 62 and having an operating handle 100 is provided for shifting the movable jaw 88 to open the clamp. As shown this shaft carries at the end of a crank arm99, a cam roller 101 adapted to engage the downwardly-turned end 102 (Fig. 1) of a link 103, having a sliding engagement with the anvil 62 at 103* and pivotally connected to the movable jaw of the clamp at 104.

A clamping member 105 is provided for securing the shoulders of the garment Z against the margins of the ironing plate 63. As shown, this clamping member is pivotally attached to the anvil 62 at 106 and 107 (Fig. 7), and is provided with gripping jaws 108 and 109 for engaging the margins of the ironing plate at either side of the neckbandengaging flange 70. 105 is operated by a crank shaft 110, jourrele in th anvil 62 and provided with The clamping member and yieldingly connected thereto by a spring i 114 reacting against the outer end 116 of the that its movement in the arc of a circle may produce only a rectilinear movement) to a pitman. A pan 62, carried by the anvil 62, shipper arm 147 leading to the belt shipper surrounds the ironing plate 63 to support the skirt and sleeves of the garment.

Power is applied to the machine for driving the ironing roller 25 and oscillating the ironing table 28, preferably through a belt pulley 117 which, as shown, is loosely mount ed on a stub shaft 118 carried by one of the 11 nights, as 15, of the supporting frame. Idle pulleys 129'and 121, for carrying driving belts, not shown, which run in opposite directions, are mounted, one at either side of the driving pulley 117, and one of them, as 120, turns on the huh of that pulley. A belt ship )er 122 ilays over the pulleys to shift the elts and control the operation of the machine.

Power is transmitted from the driving pulley 117 and a gear pinion 119 formed on its hub beyond the pulley 120, to the ironing roller 25 and the ironing table 28, through a speed-reducing train of gears, including a gear 123 and pinions 124, 128, respectively, mounted on the shaft 37, Fig. 5. A gear125, rotatably secured to the frame of the machine at 126 (Fig. 1) transmits power from the pinion 124 on the shaft 37 to a gear 127 mounted on the trunnion 23 of the ironing roller 25, and the pinion 128 turns the driving gear 32 of the ironing table mechanism through a gear 129 mounted on the end of the shaft 35.

Provision is made for angularly adjusting a gear of the train which operatively connects the ironing table mechanism and the ironing roller, in order that the neckband engaging flange of the ironing table and the cavity 71 of the ironing roller may be caused to accurately register to shape the neckband of a garment. As shown, the gear 127 is ad justably mounted on the trunnion 23, a collar 130 being secured in position on the trunnion by means of a key 131 and having ears 132 and 133 which embrace a lug 134 projecting from the face of the gear 127 and adjustably control its angular osition through setscrews 135, 136, each raving a threaded engagement with one of the lugs. A set-screw 137 pierces the hub of the gear 127 to fix it in any ad'usted position.

The elt shipper 122 iseontrolled by mechanism including a treadle 138, mounted in a conveniently accessible position at the front of themachine u n the end of a shaft- 139 journaled in the orizontal frame members 17 and 20. A crank arm 140, Figs. 3 and 4, rises from the treadle shaft 139 at the rear of the machine and is connected by a link 141 to the crank-arm 142 of an upright rock shaft 143 journaled in lugs 144 and 145 projecting from the vertical frame member 15, and a crank-arm 146 (Figs. 1 and 8) formed on the rock shaft 143, is loosely connected (in or er 122. Most conveniently the shipper arm 147 extends through the stub-shaft 118, which is made tubular for that pur ose.

To start the machine t e treadle is depressed by the attendant and a spring is provided for raising the treadle to shift the belts and reverse the direction of movement of the machine whenever the treadle is released by the attendant. Automatic means, acting with suflicient force to raise the treadle in spite of pressure exerted thereon by the attendant, are also provided for'reversing the direction of movement of the machine when the ironing table has reached the limit of its backward travel, and the machine is automatically stopped when the ironing table reaches the limit of its forward travel. To raise the treadle 138 whenever it is released by the attendant, a spring 148 (Figs. 3 and 4) reacts between a crank-arm 149, carried by the treadle shaft 139, and a lug 150 projecting from the horizontal frame member 20. To shift the belts when the ironing table reaches the limit of its movement in each direction, a shi per rod 151, operated b the swinging of tfie table-guiding arm 33, as a sliding engagement with a crank-arm 154, carried by the upright rock shaft 143, and is provided with stops 152 and 153 which ongage the crank arm to turn the rock shaft.

As the position of the ironing table 28 is such, near the end of its rearward travel, shown by dotted lines in Fig. 2, that its weight operates to continue the movement of the machine, the shifting of the driving belts from one extreme position to the other to reverse the direction of movement of the machine, is readily effected by so arranging the stop 152 on the shipper rod 151 that it will engage the crank-arm 154 to impart .a full stroke to the rock shaft 143.

In order that the machine may be brought to rest at the end of the forward stroke of the table without shock to the arts, rovision is made for shifting the driving be ts to their limit of its orward strolie. T he shipper rod 151 is ieldl ly connected by a spring 157 to the ta le-guit mg arm 33, and carries a stop 166 which prevents the rod traveling forward farther than is required to turn the, The stop rock shaft 143 to its mid position.

166'is adapted to engage a fixed part of the machine, as the horizontal frame member 20. A pin 155'carried by the arm 33 moves in a slot 156 formed at the end of the shipper rod 151, and is provided at its outer end with a disk 158 for preventing the lateral displacement of the rod on the pin. The spring 157 reacts between the disk 158 and an adjusting screw 159 carried by a collar 159 mounted on the rod. Y

The forward movement of the ironing table is limited by the engagement of the guiding arm 33 with the table-supporting rollers 29 and 30, and preferably a brake is provided for retarding the movement of the parts when the ironing table approaches the end of its forward travel to avoi shock when these parts come into contact. As shown this brake takes the form of a band 160, Figs. 1 and 5, surrounding a pulley 160 mounted on the shaft 35, and has one end rigidly secured to the oscilla table frame 36 at 161 and the other attached to the lower end of a lever 162 pivotally secured to the frame 36 at 163, and having its longer end rojecting into the path of a stud 1'64 carried by the ironing table. the horizontal frame member 20, is enga ed by the guiding arm 33 when the ironing ta le 28 reaches the limit of its rearward movement.

In using the device the garment to be ironed is secured to the ironing table 63 preferably by means of the clamps already described, and has its neckband y surrounding the neckband holder 170 and its bosom spread upon the face of the ironing board in front of the holder. The machine is then set in motion by depressing the treadle 138, the ironing table traveling backward beneath the ironing roller 25 (the neckband holder 170 intermeshin with the cavity 71 of the roller) until the Til-nit of its backward movement is rezi leased by the attendant. The driving belts are then shifted upon the pulleys 1 17 120 and 121 to cause the ironing table and the ironing roller to travel in the opposite direction, if at the limit of backward movement of the ta ble, by reason of the engagement of the sto 152 with the crank-arm 154 of the rock sha t 143, or if because of the release of the treadle by the attendant before the limit of backward movement of the table is reached, by reason of the turnin of the treadle shaft 139 and rock shaft 143 y the s ring 148. The direction of movement of the ironing table may be reversed at any time during its forward travel by depressing the treadle 138, but if permitted to com v lete its forward stroke, the machine will t en be brought to rest by the engagement of the stop 153 of the ship er rod 151 with the crank-arm 154 of the, elt shipping mechanism. As the driving belts'are thrown to the proper position to A buffer 165, carried by ched, or until the treadle 138 is redrive the machine in one direction when the treadle 138 is depressed and in the opposite direction when the treadle is raised, this treadle may be operated to cause a continued oscillation of the ironing tool over any part of the garment, such a movement comprising a full stroke of the machine in each direction being effected, as shown, by depressin the treadle at the end of each forward stro e'of the ironing table and holding it down until the following rearward stroke has been completed. The work may be smoothed upon the board by the hands of the attendant, as it advances to the ironing tool, and if for any reason the ironing does not progress satisfactorily, the ironing tool and ironing table may be instantly disengaged by shifting the lever 55 to lower the table and the parts permitted to return to the position of starting.

The overhanging lip 72 at the walls of the cavity 71 formed in the ironing roller 25 may be accurately shaped to fit the neckbandengaging flange of the ironing table, and the parts may be adjusted to cause this cavity and the flange to properly register by adjusting the angular position of the ear 127 on the trunnion 23 of the ironing rol er, this being easily effected, as shown, by turning the set- screws 135, 136, of the collar 130. Preferably the gears connecting the ironing roller 25 and the ironing table 28 with the drying pulley 117 are so proportioned that the surface speed of the ironing roller and the ironing table are substantiall the same, For this reason there isno sli ing of the ironing tool over the garment, and a so-called domestic finish is produced. If desired, 'however, these gears may be so related in size that the ironing roller will be driven at a greater or less speed than that at which the table moves, and a sliding of the ironing tool over'tlie arment will be thereby effected and a polis 16d surface produced.
