SHIRT-IRONING MACHINE.

SPECIFICATION forming part of Letters Patent No. 429,076, dated May 27, 1890.

Application filed March 8, 1889 Serial No. 302,490. (No model.)

To all whom, it may concern.-

Be it known that I, CLARENCE 0. WHITE, of Minneapolis, in the county of Hennepin and State of Minnesota, have invented a certain new and Improved Shirt-Ironing Machine, of which the following is a specification.

This invention relates to improvements in machines that are designed for ironing the bosoms of shirts, and the obj ect- I have in view is to provide an improved machine by means of which the shirt-bosoms may be ironed in one direction only, the pressure of the roll being removed or the roll being entirely raised from the shirt while it is being passed in the opposite direction beneath the roll and the motion of the table being reversed by raising the roll.

Other objects of the invention will appear from the following detailed description, taken in connection with the accompanying drawings, in which Figure 1 is aside elevation of my machine. Fig. 2 is a plan of the same. Fig. 3 is a longitudinal vertical section. Figs. 4C, 5, 6, and 7 are details.

In the drawings, 2 represents the frame of the machine, which may be of any suitable construction. Mounted in bearings on the frame of the machine is a suitable shaft 3, which is provided with a driving-wheel 5, which is preferably a friction-wheel, and with a pinion 7. A track-frame 6 extends lengthwise of the upper part of .the frame of the machine, being pivotally supported upon the shaft 3. One end of this track-frame is provided with a supporting-rod 8, which is preferably threaded and provided with the adj usting hand-wheels 9, which engage a cross-bar on the machine-frame, through which the rod 8 passes. The interiors of the hand-wheels act as nuts upon the rod 8, so that by turning these wheels the rod may be moved up or down, as desired. By this means the forward end of the track-frame may be raised or lowered for the purpose of adjusting the trackframe.

The track-frame 6 is provided upon its upper surface with ways 10, upon which travels a reciprocating table 11. This table is provided upon its under surface with a rack-bar 13, which meshes with the pinion 7 upon the opening.

shaft 3. Supported upon the table 11 is a suitable ironing-board 15. The ironing-board will usually be provided upon its upper surface with a suitable cloth covering 16. A U shaped opening 18 is formed in the end of the ironing-board to receive the neckband of the shirt. A lever 19 is pivoted upon the ironingboard beneath the opening 18 and supports a plate 20, somewhat smaller than the opening 18, but of substantially the shape of said A bar 21 is secured to the plate 20 and extends across the end of the ironingboard. A rod 22 is supported in the table 11, and is provided with a suitable handle 23 and at its opposite end with a short crank-arm 24.

A link 25 connects the crank-arm 24 with the lever 19. By turning the rod 22 into the position shown in Fig. 3 the plate 20 may be raised above the top of the ironing-board and the bar 21 be moved slightly away from the end of the board. By turning the rod so as to move the crank-arm downward the plate 20 may be depressed and brought into the opening 18 and the bar 21 be clamped firmly against the end of the board at each side of the opening 18.

Upon the frame 2 at each side of the trackframe 6 are the standards 26, which support the shaft 27. Arms 28 are secured upon the shaft 27, and they are provided with bearings for the hollow ironing-roll 29. This roll is of ordinary construction and may be heated in the usual way. The shaft of the roll is provided with a pulley 30, having a beltface 31, to which a driving-belt 33 is applied, and with a friction driving-face 32. A friction-pulley 34 is also arranged upon the shaft of roll 29. The pulley 34 is arranged over the face of the wheel 5. One of the arms 28 projects in the rear of the shaft 27 and is provided with a stud 35,'which is arranged in a slot in the arm and made adjustable therein by means of a set-screw 36. A double friction-pulley 37 is mounted on the stud 35. One face of this pulley isin engagement with the face 32 of the wheel 30. The other face of this pulley is adapted to be brought into engagement with the face of the wheel 5. As here shown, the two parts of the pulley 37 are of unequal diameter. The portion of the pulley having the larger diameter is here shown in engagement with the face 32 of the driving-wheel 30. 3y removing the pulley from its stud 35 and reversing it and changing the position of the stud by means of the set-screw 36 the smaller portion of the pulley maybe brought into engagcmentwith the driving-wheel. The wheel 5 will then be driven at a greater speed. Power being applied to the wheel 30, the ironing-roll will be constantly rotated, and when the friction-pulley St is in engagement with the wheel 5 the shaft- 3 will be driven in one direction and the ironing-board will be advanced beneath the roll.

Yhen the pulley 37 is in engagementwitll the wheel 5, the shaft 3 will be driven in the opposite direction and the movement of the table will be reversed. As the ironing-board is advanced, I depress the ironing-roll and apply pressure thereto, so as to hold it down firmly upon the surface of the ironing-board. As soon as the ironing -board has passed wholly or partiallybeneath the roll the pressure is relieved and the roll is raised either so as to entirely remove it from the cloth or so as to leave it in contacttherewith, but causing but slight pressure thereon. The motion of the table upon which the board is supported is then reversed and the board is then carried back beneath the roll, and while so passing the roll does not touch the surface of the shirt upon the board, or if it does touch it it applies but slight pressure thereto. I provide means for raising and lowering the ironing-roll and bringing first one friction-pulley and then the other into engagement with the wheel 5. A lever i0 is secured to the arm 28 and extends toward the lower part of the frame 2. A treadle i1 is pivoted upon the frame 2, and is connected by a rod 42 with the levertt). A spring 43 is connected to the frame 2 and to the lever 40. This spring tends to depress the rear end of the arm 28, and thereby to hold the rear frictionpulley in engagement with the wheel 5 and the ironing-roll in its elevated position. 13y depressing the treadle -11 the arms 28 are turned together with the shaft 27, the rear friction'pulleyis carried away from the wheel 5, the forward friction-pulley is brought into engagement therewith, and the roll is depressed and broughtinto position to act upon a shirt placed upon the ironing-board. \Vhen neither one of the friction-rolls is in engagement with the wheel 5 the shaft 3 and the table will remain stationary. I provide an automatic stop that is operated by the table, and throws the frictiona-olls out of engagement with the wheel 5 when the table has been brought into position for having a shirt removed from or applied to the board.

A bell-crank lever 4:9 is pivoted upon the track-frame (J, and its short arm is arranged to engage the lever 40. A ing is arranged upon the side of the sliding table, and when the table reaches the end of its reversemovement this lug strikes the long arm of the lever 4-9 and throws its short arm against the lever 4:0, thereby moving that lever a sutiieient distance to raise the rear friction-roll from the wheel 5 without bringing the forward frictionroll into engagement therewith. 130th friction-rolls are now out of engagement with the wheel 5, and the shaft remains stationary.

A brake-rod 51 is arranged to move vertically upon bearings 52 and 58, and is provided with a brake-shoe 53, that is adapted to be brought against the face of the wheel 5. A red 5i is pivoted to the frame of the machine, and is connected to the rod 51 by means of a short rod 55. Alink 56 is joined to the rod 5; and to the lever -1t0. The rods 5t and together form a knuckle-joint. \Vhen the rods 54c and 55 are in line with each other, the brake-shoe will be raised against the wheel 5, and this wheel and the shaft 3 will be held stationary. \Vhen the center of the joint is thrown to either side of the center, the rod 51 drops down, so as to bring the brake away from the wheel 5'. Vhen the lever 40 is moved by the bell-crank lever 49, as the table reaches the limit of its receding movement, the knuckle-joint will be straightened out, the brake applied, and the table stopped. The treadle will then be depressed and the parts of the joint broughtinto the position shown by dotted lines in Fig. 3. The table will then begin to advance. \Vhen it is depressed, to reverse the movement of the table, which can be done at any point in its travel, the pressure is removed from the treadle and the spring 43 draws back the lever 4.0.

The operation of the machine willbe readily understood from the foregoing detailed description.

The shirt is placed on the ironing-board, the neckband being turned under the plate 20. This plate is then depressed, turning the neckband into the opening, and bringing the clamp 21 against the shoulders of the shirt clamps them upon the end of the ironingboard. The treadle is then depressed and the table advanced, carrying the ironing board beneath the roll, which is now brought with considerable pressure upon the bosom of the shirt. As soon as the table has passed the shirt-bosom beneath the roll the pressure is removed from the treadle and the ironingroll is slightly raised, either carrying it wholly clear of the cloth or leaving it in con tact therewith, but with only a slight pressurc upon the cloth. As soon as the pressure is removed from the table the knuckle-joint connected with the brake-rod is straightened out, thereby pressing the brake-shoe against the wheel 5 and stopping it. The movement of the lever 40 continues and carries the knuckle-joint by the center, bringing the parts into the position shown by full lines in Fig. 3, thereby removing the brake and bringing the rear friction-roll into engagement with the wheel 5 and reversing the machine. The table recedes, and when it reaches the backward limit of its travel it operates the bell crank lever, which raises the rear friction- IIO roll, leaving both friction-rolls out of engagement with the wheel 5, and applies the brake to that wheel.

Suitable gear-wheels might be substituted for the friction-Wheels without departing from my invention.
