IMPROVEMENT IN STARCHlNG-MACHINES.

Specification forming part of Letters Patent No. 135,171, dated January 21, 1873.

To all whom it may concern:

Be it known that I, LEOPOLD STEENBER- GER, of Philadelphia, Pennsylvania, have invented an Improved Starching-Machine, of which the following is a specification:

The object of my invention is a machine for rapidly and thoroughly rubbing starch into and through the fabric of shirts and other articles of wearing apparel. I accomplish this object in the manner best observed in the perspective view, Figure 1, of the accompanying drawing, by combining an oscillating or vibrating rubber, A, operated rapidly from a power-driven crank-shaft, B, with a rubbingbed, D, rendered vertically adjustable toward and from the rubber by means of a treadle, E, and connecting-rod a, the said treadle also controlling the belt-shifter b, through the medium of the devices hereafter described, so that when the bed is raised by the said treadle, and the shirt or other article brought in contact with the rubber, the latter shall be instantly set in motion, and be similarly stopped when the bed is lowered.

The rubber A is secured to a vibrating arm", 0, pivoted at d to a post, 0, projecting upward from the frame of the machine, the said'arm being connected by a rod, f, to a short crank, g, on the shaft B, which has fast and loose pulleys at one end, into either of which the driving-belt can be passed by the shifter 12, the latter, as best observed in Fig. 5, being connected to a slotted arm, h, hung to a bell-crank lever, I, which is, in turn, connected by a rod, j, to the connecting-rod a, between the operating-treadle and the rubbing-bed D. The latter is adapted to vertical guides on the frame of the machine, and is free from contact with the rubber A, except when raised and held against the same by pressing upon the treadle E; and the said bed has a ledge or flange, k, at the back, as shown in the perspective view, Fig. 2, and a concavity, 1, within which the rounded face m of the rubber works.

In using the machine the operator places a starched shirt or other article upon the rubbing-bed immediately beneath the rubber A, and by pressing upon the treadle simultaneously starts the rubber and raises the bed so as to press the shirt against the same. The rubber vibrates very rapidly, and by the pressure of its rounded lower surface upon the shirt thoroughly rubs the starch into and through the same, the position of the shirt being shifted as it is rubbed until every por tion is reached.

The rounded surface of the rubber fits snugly into the concavity of the rubbing-bed, which retains the starch, and thus much facil itates the operation.

It will be observed, in reference to the perspective view, Fig. 3, that the rubber has a recess, 19, at the back. This is for the passage of the buttons in starching shirts, the latter being turned inside out and then folded longitudinally at the center of the bosom, so that the buttons may lie against the rear flange 7c of the rubbing-bed without being struck by the rubber. In order that the space between the buttons, however, may be properly starched, a yielding stud, s, Fig. 4, is adapted to the recess p of the rubber, and is so arranged that it will ride over the buttons and rub the spaces between the same.

I claim as my invention- 7 1. In a starching-machine, the combination, substantially as described, of an oscillating rubber, A, with a rubbing-bed, D, rendered adjustable toward and from the said rubber.

2. The oscillating rubber A, with its rounded face m and recess 19, in combination with the concavity I) of the rubbing-bed.

3. The combination, substantially as described, of the yielding stud s with the recessed rubber A and rubbing-bed.

4. In a starching-machine, the combination, substantially as .described, of the operatingtreadle E and connecting-rod a of the rubbing-bed with the rod j, bell-crank lever c, slotted arm h, and belt-shifter b, or any equivalent devices, whereby the oscillating rubber may be set in motion simultaneously with the raising of the bed by the treadle, and stopped simultaneously with the lowering of the said bed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

LEOPOLD STERNBERGER.
