STARCHlNG-MACHINE.

SPECIFICATION forming part of Reissued LettersPatent No. 11,109, dated September 2, 1890. Original No. 400,184, dated March 26, 1889. Application for reissue filed June 6, 1890-. Serial No. 354,517.

To all whom it may concern:

Be it known that I, THOMAS J. BLAKE, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Starching-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form part of this specification.

This invention has relation to starchingmachines, and especially to thatclass of machines particularly designed and adapted for starching shirts and other large articles of underwear.

The object of my invention is to provide -means'whereby the starch will be forced into and through every part of the fabric, while ample and efficient provision is made for the escape of the air from the folds and cavities while the articles are being pressed.

My invention has. for its further object the.

provision of novel means for automatically removing the surplus starch from eacharticle after it has been thoroughly saturated or impregnated.

My invention consists in the novel con-- struct on, combination, and arrangement of.

parts, as hereinafter described, and specifically claimed.

In the accompanying drawings. Figure 1 is an end view, and Fig. 2 a side elevation, of

my improved starching-machine, and Fig. 3

a detail view of the mat.

A designates a rectangular frame, upon which are supported the working parts of the machine.

B B are standards or brackets supporting above the frame .A the perforated cylinder 0 and the pivotal arms D D, which carry the wiping-roller 0 E designates the starching-table, which consists of a shallow oblong metallic box having a horizontal surface and adapted to contain hot water, which is supplied thereto from a boiler by means of a hose e. This table is mounted on a platform F, to which are journaled rollers or wheels f f, arranged to travel toothed segment H, fitted to said shaft and engaging withthe teeth of the" rack C.

To the upper surface of the table E is secured a web or mat-I, consisting of asheet of rubber having its surface indented so as to form a large numberof cavities to receive and hold the starcl1,'which is fed thereto in any convenient manner.

5 The roll 0 is preferably constructed of brass or copper in the form of a hollow cylinder or shell and is mounted on a shaft 0, having its 'ends supported in the side pieces or brackets B B. The cylinder 0 rotates upon its shaft, while the ends of'the latter rest/upon springs b b and are pressed down by means of rubber blocks (1, to whichare attached adj ustingscrews d d, turning in bearings in the tops of the brackets-B B and provided with handwheels d on theirupper ends. The cylinder 0 is perforated, the holes being preferably arranged in close proximity, so as to allow the air to escape from the fabric when the starchin -table is passing under the cylinder and into the cylinder. When a solid or imperforated cylinder is used, no escape for the air is provided, and its accumulation and retention inside the folds of the fabric greatly interferes with the entrance of the starch and thorough impregnation and saturation of the articles. The starch on the surface, instead of being driven into and through the. fabric, is forced back by the roll onto the table or oif onthe sides or ends. The cylinder C-is so situated that its surface and the surfaceof the mat 1' upon the table are in close pressure contact when the latter is passing under the cylinder. The pressure, however, is not rigid, but is made yielding by the rubber blocks d, whichallow the cylinder to adaptitself to the varying thickness of the goods.

The wiping-roll 0 consists of a cylinder, of

wood or other material, having a cloth cover in several folds 01' layers, and is intended and adapted to be swung down upon the starch-' ing-table in contact with the goods at inter- 5 valsthat is, after the table has passed a suflicient number of times under the perforated roll and the goods have taken up enough starch the wiping-roll takes up the surplus starch from the goods and leaves them in con- IO dition for the next operation.

In the machine under consideration the wiping-roll is brought into play after every fourth movement of the starching-table, and its action is governed by the mechanism to be described.

The arms D D, by which the wipingroll is carried, are attached to a transverse shaft M, journaled in the arms is k, projecting from the edges of the brackets B B. The arm D is formed or provided at'its lower end with a toothed segment k, which engages with a toothed lever 70, pivoted to the side of one of the brackets B B. At its lower end the, lever k is coupled by means of a lateral pin 2 5 or pivot k, passing through a slot k in a swinging bar Z, which is pivoted at Z to one of the sides of the frame A, the several parts being so arranged that any motion imparted to the bar} will be transmitted to the arms 0 D D. Normally the armsDD are in an upright position,as shown in black lines in Fig.

1, the wiping-roll being nearly directly above the perforated cylinder. The shaft M, supporting arms D D, is journaled about on a 3 5 line with the shaft of the roll C, and the arms D D are bent at e to allow the wiping-roll to reach the table. In the position shown the arms are maintained until otherwise required by the tension of a spring N upon the bar Z,

40 which also serves to return the wiping-roll to the position shown after it has done its work.

The movement of the wiping-roll is effected through the medium of an offset or cam m on the face of a toothed wheel m, journaled 5 to the frame A. A transverse main powershaft N carries a pinion N, which engages with the wheel m, and is proportioned so as to make four revolutions to one of the wheel m.

Upon one end. of the shaft N is a crankwheel 0, which is connected by a pitman O with a crank-wheel O on the end of the shaft H, so that the revolution of the wheel 0 will produce an oscillation or reciprocation of the wheel 0 and rectilinear or horizontal recip- 5 5 roeation of the starching-table through the medium of the segment H and rack C.

At every fourth revolution of the shaft N and every single revolution of the wheel m the offset or cam m comes in contact with and swings or moves the bar Z to one side,

thus causing the wiping roll to fall upon or in the way of the starching-table, where it remains during the backward movement of the table from beneath the cylinder C and 6 5 gathers up the starch remaining unused upon the surface of the goods. After the cam an has passed the bar I the latter is thrown back into position and the wiping-roll is raised.

The wiping-roll and shaft are detachable, so that when the former has accumulated a large amount of starch it can be taken out and soaked in warm Water to wash out the starch, a new roll being meanwhile substituted. For the purpose ofallowing the wiping-roll with its shaft to be detached the arms D D are notched, as shown at D to receive the ends of the shaft, which is held in place by removable pins D The main shaft N is provided with suitable clutch mechanism P, whereby it may be thrown into and out of gear with the toothed wheel T in mesh with pinion t on main pulley-shaft s.

S S are fast and loose pulleys which carry a shifting-belt Q, by which the machine may be started and stopped at pleasure.

The clutch P is employed in stopping and starting the machine between starching operations.

Having described my invention, what I claim, anddesire to secure by Letters Patent,

1. In a starching-machine, the combination I of a starch-containing table or carrier upon which the articles to be starched are laid and a presser for forcing the articles against such table, and provided with perforations for the escape of air, substantially as set forth.
