To all whom it may concern:

Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Bosom-Presses, whereof the following is a specification, reference being had to the accated at a convenient point to be manipucompanying drawings.

My invention relates to a laundry machine I commonly known .as a shirt bosom press,

which is pneumatically operated. In machines of this type, there are employed a I plurality of movable members withpadded surfaces upon which the goods are placed and which are forced 1n succession agalnst a heated stationary member, whereby pressure is exerted to secure the required finish. I

By my invention I secure an easy and uniform control and operation of such a machine by'means of'the application of pneumatic power. air from the pneumatic cylinder for the purpose of drying the padded heads of the movable member and thereby greatly economize in the power necessary to operate these machines, and also simplify their construction and reduce their cost.

.In the accompanying drawings, Figure I, is an elevation of a shirt bosom press conveniently illustrating the application of my invention thereto. Fig. II, is a cross sectional view of the padded head employed in the press.

The device consists of a bed frame or base 1, which supports near its ends apair of posts 2, and 3, whose tops are reduced to form shoulders which are bridged by a yoke 5, secured in place by nuts 6. The yoke 5, supports ahollow steam chest or headlO, constituting the fixed member of the press, and having a circular opening 11, in which is received the neck band of theshirt. The lower face of this head is highly polished and maintained at the required temperature by means of a steam pipe 12, which extends from some suitable source of steam supply, and communicates with its hollow interior.

Pivotally mounted on the post 2, is a swinging turntable 15, having the laterally The said heads are arranged to be alter-- nately swung under the stationary steam I further employ the exhaust chest 10, against which either one so swung is forced by means of the piston rod 25, of the pneumatic cylinder 26, which is bolted or otherwise secured to the bed 1. The operation of the piston 27, of the said cylinder is under the control of a slide vvalve 28, incased within a valve chest 29, which is lated by the feet of the operator by means of a double foot lever 30, which is pivoted at 31,-to a lug formed on the top of said chest. The foot lever 30, comprises the arms 32, and 33, to the latter of which is pivot-ally attached a rod '35, which slides through a stuffing box at the top of the chest and is secured at its lower end to the valve 28; The said valve is maintained in airtight contact with the inner face of, the wall 36, of the chest 29, by means of a spring 37, which is in engagement with the back there of, and maintains it in whatever position it is placed by the foot lever 30. The said chest is in communication with a source of plied and exhausted through a pipe 45,

which extends from its bottom" to the right side of the valve chest 29, and is arranged to exhaust through the recess 46, in the slide valve 28, into a pipe 50, which also extends from the right side of the valve chest in close proximity to the pipe 45. The exhaust pipe 50, communicates witha duct 51, which communicates with branch ducts 52, and 53, extending respectively through the arms 16, and 17, of the turntable 15. These lead to vertical ducts 55, in. the stems 20, which terminate in the chambers 56, of the heads 21. As best seen in Fig. II, the tops of said heads are provided with a plurality of apertures 57, through which the exhaust air finally escapes. The heads are covered with pads 58, of felt or other suitable material secured by means of a textile fabric 59. During the process of pressure ironing, this pad absorbs the moisture previously applied to the shirt bosom, and the air which exhauststhrough the apertures 57, is per-' mitted to pass through the pad and thus eliminates this moisture upon the completion of the ironing of each shirt.

The operation of the device is as follows :The dampened shirt bosom is stretched across the top of one of the heads 21, in a well known manner and the turn- H table 15, is thereupon swung, so that its piston causes the stem 20, to be elevated thus forcing the head 21, against the stationary steam chest 10. The shirt bosom is thus permitted to remain under pressure for a proper interval of time against the heated head. After this period has elapsed, the arm 33, of th foot lever is depressed and the valve 28, is thereby shifted to the position shown in the drawing. The Weight of the piston 27, and the acting stem 20, causes the entrapped air to be forced from the cylinder 26, into the pipe 45, wherefrom it escapes through the recess 46, of valve 28, into the pipe 50,,and through ducts 51, 52, 53, and 55, into the chambers 56, in the heads 21, where it finally asses out through the apertures 57, and padding 58, in a manner and for a purpose hereinbefore explained.

Having thus described my invention, 1 claim I In a bosom press, the combination of uprights and a yoke supporting a heated stationary member; a plurality of padded movable members mounted each upon a stem seated in an arm swinging upon one of said uprights; a pneumatic cylinder having a piston rod capable of engagement with the stem of whichever movable member is in posit-ion to cooperate with the stationary member; a pneumatic valve by means of which compressed air is admitted into said pneumatic cylinder to operate it; and ducts passing through said upright and swinging arms, the pneumatic valve chamber communicatin with one of said ducts, whereb the air ex austed from the pneumatic cy inder is caused to ass through the padded heads of said mova le members.

In testimony whereof, I have hereu to signed m name, at Philadelphia, Pennsylvania,'th1s thirteenth da of Janua 1911.
