SPECIFICATION forming part of Letters Patent No. 397,700, dated February 12, 1889. Application filed April 23, 1888. Serial No. 271,542. (No model.)

To all whom it may concern:

Be it known that we, \VILLIAM F. (REVERT and JOHN CLAUS, both of the city, county, and State of New York, have invented anew and useful Shirt-Clamping Attachment for Ironing-Machin es; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this speci tication, in which- Figure] isaplan viewof the reci n'ocating ironing-table in an ironirig-machine having our imprm'ementattached thereto, the ironing-rollerbeing shown as partly broken away to disclose the clamping device beneath it. Fig. 2 is a horizontal vertical section on an enlarged scale in line a: a. of Fig. 1, illustrating more fully the construction and operation of our improved clamping device.

The object of our invention is to provide means for fastening the neck portion of the shirt to the end of the reciprtmating ironingtable in a manner to avoid the liability of creasing and rumpling the shirt-bosom after it is stretched over the table; and our invention especially adapted for attachment to an ironing-machine constructed and operated substantially as described in the patent to L. H. Vi atson, dated February 12, 1852-], No. 293,290. In the accompanying drawings, A A represent the frame of theironing-maehin e, and B the hollow ironing and polishing roller, mounted to rotate in suitable journal-boxes fitted upon the frame.

C represents the ironing-table, arranged to travel back and forth under the ironing-roller in any suit-able manner, but; preferably in manner described in the aforesaid Letters Patent No. 293,290, by means of a carriage or The means for imparting the appropriate horizontal and vertical reciprocating more men to the ironing-table under the ironing roller need notherein be described, as they constitute no part of our invention, and are well. known to the art.

The improved clamping device for binding the neck portion of the shirt to the movable ironing-table after the shirt has been prop- 1 erly stretched thereon consists of two arms, 1 G (i, projecting from collars ll ll, fitted upon a rock-shaft, I, mounted parallel with and in front of the end of the ironing-table in bearings K 'h, fixed to the carriage-frame D, so as to be carried thereby with the table in its movements. 'lhesc arms (1 (i, when properly adjusted on the rock-shaftl, are fixed thereto by means of set-screws J' .T. They extend up vertically from the rock-shaft to a height which brings their upper (lUlSttlJOYP the level of the ironing-table, and threaded rods L L are passed thrtmgh simple apertures therein to work freely through the same and to extend horizontally on a level with the edge of the table when the arms (l (tare in a vertical po sition, so that the forward ends of the rods will strike against the edge of the table. When thus adjusted, eat-l? rod ismade fastby means of nuts M l\li,runn lug upon the thread ed body thereof from opposite sides of the arm to close against it. The front ends of these rods bearing against the edges of the ironing-table are plOYltltfti with serrated plates or clamps N N, adapted to take hold of the fabric of the shirt drawn over the edge of the table and prevent it from slipping when confined. thereby against said Mtge. The clamps are held against the front end or edge oi. the table or the interposed fabric with a firm yet elastic pressure by means of a spiral spring, 0, encircling a vertical rod, 0', mounted under the opposite end of the table to play vertically through a perforated plate, tit-ted on the carriage l). The spring resting at its lower end upon said plate operates to force the rod upward, and is compressed by a downward movement of the rod. The upper end i of the rod is pivoted to one end of. a lever, P,

of the first order, pivoted at t to the neck E, the lever being made to extend from the upper end of the rod 0' with a downward inclination, so that its lower longer end may rest upon a block, Q, fitted upon a frame, Q, adapted to slide longitudinally in ways F, fixed upon the track-frame F parallel with the ironing-table just below the level of the base of the carriage D. The lower longer end of the lever P is pi voted both to the free end of a second lever, P, of the third order, extending normally in a horizontal position, and which is pivoted at its opposite end to the base of the carriage D under the front end of the ironingable, and also to a link, P extending therefrom with an upward inclination to the upper end of a short crank-arm, I, projecting upward radially from the rock-shaft l.

The tension of the spring 0 upon. the outer end of the lever P, tending to force it upward, operates to bear down the lever P and to draw the link P downward, and consequently to pull the crank-arm 1" toward the ironingtable, thereby turning the rock-shaft I, so as to cause its arms G G and the clamping-rods L and clamps N to move and press toward and against the edge of the table.

The arms G G are thrown back and the clamps l thereby withdrawn from the edge of the table, as shown in dotted lines in Fig. i, by lifting the free end of the horizontal lever 1 and with it the end of theleverP andof the link P so as to move the crank-arm P of the rock-shaft and cause it to turn and swing back said arms G G.

The uplift of the end of the level-P is produced when it is required to withdraw the clamps by means of a movement of the sliding block Q, upon which said end rests, the block being formed. with an inclined surface, 072, to engage, when the block is moved forward, a large friction wheel or roller, R, journaled upon the lever P. As theinelined portion of the block passes under the wheel it will operate to lift the lever P.

The movement of the block Q under the wheel R maybe produced at will by a crankarm, S, Fig. 1, actuating a rock-shaft, S, mounted transversely under the end of the track-frame F, and which is provided with a radial arm, 8*, connected by a link, S to the block Q, as shown in Fig. 2. The block Q may also be so adjusted that, in the regular movements of the ironing-table C, the frictionwheel R of the level-P will be carried up the inclined face on of the block at the moment when the ironing-table, having completed its movements, returns to its first position, so as to provide for an automatic withdrawal therebyof the clamps from the table at said moment.

It is evident that any known form of spring may be employed as an equivalent for the spiral spring 0 to actuate the end of the lever P and force it upward, and also that various mechanical devices will readily suggest themselves to a skilled mechanic for forcing the lever P upward as an equivalent for the in cline m upon the sliding block Q, this device being illustrated and described in this connection by reason of the fact that it is found in the machine described in the Patent No. 293,290, and to which our invention, as has hereinbefore been stated, is especially applicable.

\\'e claim as our invention 1. The combination, in an ironing-machine, with its iron in g-table', of the movable carrriage supporting the same, the clamping-plates e11- gaging the edge of the table, the transverse rock-shaft mounted upon the carriage and upon which said plates oscillate, a crank-arm projecting upward from the rock-shaft, a horizontal lever pivoted at one end to the can riage below the rock-shaft, a link connecting the free end of said lever with the crank-ar1n, and means, substantially as described, for producing an upward movement of the horizontal lever by the movement of the carriage, substantially in the manner and for the purpose herein set forth.

2. The GO1llbll12thlO1l,ll1 an ironing-machine, with the ironing-table and the carriage upon which the table is mounted, of a pair of movable clamping-plates engaging the edge of the table, a transverse rock-shaft upon the carriage, arms projecting radially from said shaft, transverse rods at the ends of said arms to which the clamping-plates are secured, a crank-arm projecting upward from the rockshaft, a lever pivoted at one end to the carriage below the rock-shaft to rest normally in a horizontal position, a link connecting the end of said lever with the crank-arm, and a horizontal slide provided with an incline formed and located substantially as described with relation to the free end of the lever, whereby, when said incline strikes the lever, the lever shall be swung upward and thereby throw back the clamps from the ironing-table, substantially in the manner and for the purpose herein set forth.

3. In an ironingqnachine, the combination, with the ironing-table, the clamps engaging its edge, the rock-shaft supporting and actuating the same, its crank-arm, the clamp-supporting arms an d rods, and the horizontal lever pivoted at one end and coupled at the other to said crank-arm, of an inclined lever pivoted at its inner end to the free end of the horizontal lever, and a spring actuating the outer end of said lever, whereby the power of the spring is made to close and hold the clamps automatically against the edge of the table, substantially in the manner and for the purpose herein set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
