MOISTURE STRAINING PRESS MAT @riginal- Filed Oct. 1,. 1928 oRNEY Patented Feb. 9, 1932 NETE STATES MOISTURE STRAINING PRESS MAT Original application filed October 1, 1928, Serial No. 309,621.
Divided and this appnceiion mea August 23, 1930. Serial No. 477,437.
This invention relates to dehydrating presses and more especially to press mats for use in machines of the class shoivn iii my application Ser. No. 309,621, iiled Oct. 1928, and of Which this application is a division. Y
A purpose is to provide a simple, practical, substantial and very durable and highly effective strainer mat for such presses.
A further object is to provide a mat of such structural embodiment that it Will readily flex over driving drums and rollers and vet will have a great degree of rigidity on transverse lines so that it Will not sag or treugh When under pressure in the machine.
The invention consists of certain advancements in the art as will be set forth in the ensuing disclosure and having, with the above, additional objects and advantages, and Whose construction, combination and details of means, and the manner of operation will be made manifest in the description of the herewith illustrative embodiment; it being understood that modifications, variations and adaptations may be resorted to Within the scope, principle and spirit of the invention as it is more directly claimed hereinafter. Y
Figure l is a plan of the improved strainer mat.
Figure 2 is a cross-section of the mat.
Figure 3 is a longitudinal section of a fragment of the mat.
A preferred form of the strong, ber selvage ropes 75 and intermedidiate warp cords 76 laid in pairs one over and one under cross-cords or weft 77 overbound on the selvage ropes.
Means are incorporated in the mat Weave to transversely stii'fen the body and consists of small Wire rods 78 lying beside the cords 77 and having their ends wrapped on the ropes 75. Thus if a Wire breaks it is still tied to the selvage ropes.
The selvage of the mat is bound with a rubber impregnation 75a.
This structure affords great flexibility along the mat and also provides a desired stiffness against any sagging of the mat transversely; the transverse rods allowing the selvage and mat to bend over rollers and mat consists of that the line loose fibre Will yet providing a bed which is reinforced from side to side.
This strainer is especially useful in apparatus for expressing moisture from peat or other fibrous vegetable matter which cannot 55"; be `successfully accomplished by ordinary strainer cloth or by Wire screen for the reason pack in the cloth interstices and Will prevent the liquid from passing through the screen. Preferably, the '-'l Warp cord is a rather heavy loose cord twine,
`Which is particularly effective for straining quality of mat because the heavy loose cord, when pressed down, forms a strainer permity ting a ready ioW of the moisture through it 1F25 and preventing the particles of the pressed fibrous material from passing through the mat. The compressed fibrous material peals freely from the mat surface and the soft cord expands to its ordinary size while the belt is traveling its orbit and back to the pressing position; the ready pealing of the matter preventing the clogging of the mat mass and thus permitting this to retain its high strainu ing efficiency. The transverse rigidity of the if mat is preserved by the transverse reinforcement Wires Which sustain the Woven mat body While traversing press bed crevces and also operating to prevent shrinkage and expansion as Well as preventing sagging.
rlhe Woof cord is preferably hard spunhemp or other fiber cord of desired strength and is, as before stated, much larger in diameter than the transverse metal bars so as to prevent the Wir-e from cutting the Warp cords 'I While under pressure.
As shown, the Wires 78 are straight and thus inextensible so that the mat will not expand laterally under pressure, and-addi- M tional, the Wires materially truss or reinforce "d the mat against sagging transversely. The Wire cross parts connect to the selvage ropes by means of helical loo-ps which provide a desired flexibility of the attachement as the mat bends around the usual tumblers in belt press apparatus.k
1What is claimed is:
A cloth press mat for dehydration Which comprises heavy selvage cords and a Warp W, system of cords, a system of straight-Wire,`
transverse reinforcing connecting and twisted along the selvage cords to prevent lateral spread thereof under pressure, and a weft system of cords each of which is of materially greater size than the selvage tie Wires, said Wires lying close to adjacent weft cords and free thereof the selvage twists of the wire being embedded in a. heavy rubber Yselvage strip.
