dQMPRESSION-TOP FOR DYE-VATS.

SPECIFICATION forming part of Letters Patent No. 780,400, dated January 17; 1905.

Application filed August 1, 1904. Serial N- 219,097.

I from pressure during the dyeing or Washing operation.

A further object of the invention is to provide a plate of the character set'forth which can be easily and quickly removed from the 2 machine.

The invention .has for its further object to construct a compression top or closure plate for dyeing machines which shall. be simple in construction, strong, durable, efficient in its 2 5 use, and comparatively inexpensive to manufacture.

To these ends the invention consists of the novel combination, construction, and arrangement of parts hereinafter more specifically 3 described, illustrated in the accompanying drawings, and particularly pointed out in the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings,

I forming a part of this specification, in which- Figure 1 is a top plan view of the plate, and Fig. 2 is a transverse sectional view on line a: w of Fig. 1. 1

Like reference characters denote like parts 4 throughout both views.

Referring to the accompanying drawings, 1 denotes a plate shown circular 1n contour,

but any preferred shape maybe employed,

and which is adapted to close and operate in a dye-vat and rest upon the material to be dyed. The plate 1 is'provided with a series of openings or perforations 2 to permit of the passage of dye liquor therethrough. Se-

perforation 7, through which 'made fast to the truss-irons 5.

cured to the upper face of the plate 1 and arranged near the edge thereof is a peripheral 5 0 angle-iron 3. This angle-iron has one of its arms extending vertically from the upper face of the plate 1 and its other arm extending toward the edge thereof and serves as a reinforcement for said edge. To strengthen the plate 1, I provide a series of radially-extending reinforcing members, preferably in the form of truss-braces, which will now be described. These reinforcing members consist of a number of truss-irons 5 of a length approximately equal to the diameter of the plate 1 and are bent at their middle into V shape,

thus having their Wide portions at the angle.

The ends of the V-shaped irons are bent toward each other to form lugs 6. 5

The plate 1 is provided at its center with a projects a bolt 8, having an enlarged head 9. The trussirons 5 are arranged upon the upper face of the plate 1, with their angular 7 portions so arranged as to form anopening at the center of the plate, so that their arms will extend radially therefrom. The lugs 6 will thus rest against the vertical arm of the peripheral angle-iron 3, to which they are secured by means of bolts or rivets.

The truss-irons 5 when secured to thplate 1 are adapted to abut against each other that is to say, one arm of each iron is adapted to abut against an arm of theadjacent iron. A washer 10 is placed upon the free end of the bolt 8 and the angular portions of the truss-irons 5 and closes the opening formed by the angles of the irons, and the said washer 10 is connected to each of the truss-irons 5 5 through the medium of a bolt 10. These bolts 10 are secured to their respective trussiron through the medium of the holdfast de, vices 10, extending through the bolts 10 and arrangement the plate is reinforced at the center thereof. A nut 11 is screwed upon the free end of said bolt and engages the Washerto securely clamp the angular portions ofthe truss-irons 5 to the plate 1. .To secure the abutting arms of the truss-irons together and By such an 9 to the upper face of the plate 1, angle-irons 12 are provided. These angle-irons 12 are arranged on one side of the abutting radiallyextending arms of the truss-irons 5, preferably opposite one another, and have one of their arms secured to the upper face of the plate 1 by rivets or bolts extending through both the arm of the angle-irons and the plate 1. The angle-irons 12 are further secured to the radial arms of the truss-irons 5 by means of rivets or bolts extending therethrough. Additional holdfast devices are employed, if desired, to assist in securing the abutting arms of the truss-irons together, and these holdfast devices are indicated by the reference character 12.

Yokes, eyes, or other suitable devices 13 are secured at intervals to the upper face of the plate 1, to which lifting-chains 14, connected in turn to a ring 15, are secured in order that the plate may be lifted from the vat when the dyeing or washing operation is completed.

It will thus be evident that when the top plate, as above described, is placed in a dyevat and pressure is applied thereto for compressing the material to be dyed in the dye- Vat the peripheral angle-iron 3 Will effectually prevent the edge of the top plate from bending or buckling, and the body of the plate will be strengthened and prevented from bending or buckling by the truss-irons 5.

In describing my invention I have described a top plate adapted to be used in a dye-vat which is circular in form; but it is to be understood that my top plate may be square, hexagonal, or of any other contour, according to the shape of the dye-vat in which it is intended to be used.

It is thought that the many ad vantages of the improved compression top or closure plate can be readily understood from the forego ing description, taken in connection with the accompanying drawings, and it will, furthermore, be evident that changes, variations, and modifications can be resorted to without departing from the spirit of the invention or sacrificing any of its advantages, and I therefore do not wish to restrict myself to the details of construction hereinbefore described and as shown in the accompanying drawings, but reserve the right to make such changes, variations, and modifications as come properly within the scope of the protection prayed.

Having thus described the invention, what I claim, and desire to secure by Letters Patcut, is
