OIL-PRESS MAT.
SPECIFICATION forming part of Letters Patent No. 276,846, dated May I, 1883.
i Application filed Ocoher 18, 1882. (No inodeLi To all whom it may concern: n Beit known that we, FREDERIC C. MANN,
of East Bridgewater. in the county of Fly` mouth and State ot' Massachusetts, and HEN- nY SCHUMACHER, of Navasota, in the county of Grimes and State of Texas, have invented certain Improvements in Oil-Press Mats, of which thefollowing is a specification.
This invention relates to mats between which cakes ot'ground cotton or other oil-yieldingseed are held while being subjected to the action `of the press which separates the oil from the cakes. The invention has for its object to provide certain improvements in the construction of such mats, whereby `they are made more efficient and durable than those ingcneral use. To these ends our invention consists in the improvements which we will now proceed to describe and claim. i
Of the accompanying drawings, forming a part of this specification, Figure l represents a top view of a mat embodying` our improvements, a part of the upper sheet of leather being removed. Fig. 2 represents an edge view of the same. Fig. 3 represents a transverse section of the Same on line a: m, Fig. 1. Fig. 4 represents a view of a part of one of the leather sheets having a notched edge.
The same letters ot' reference indicate the same parts in all the gures.
In carrying out our invention we provide two rigid rectangular frames, A A, of suitable size, and composed of bars ot' iron strongly scoured together. The space inclosed by each fra-me is covered by a sheet'of wirecloth, B, which is suitably secured to the frame. To the outer side of each sheet of wire-cloth we attach a sheet of leather, C, of such size as to cover the wire-cloth. The leather sheets are secured by detachable fastenings D, so thatV they can be removed for cleansing or renewal, said fastenings being preferably clips or staples of exible meta-l passed through the wirecloth and leather and bent over upon the outer surfaces of the latter. We prefer to interpose sheets of hair-cloth or other textile material, E, between. the Wire and the leather to prevent the Wire from indenting the leather and mutually protect both the leather and wire.
` F F to the lower frame.
`oilcakes between the leaves.
The frames A A are connected by metallic links F F F F', which are pivoted` at their outer ends to a rod or handle, H, and at their inner ends, F3, to ears on the frames, the links F F being pivoted'to the upper and the links The links F Fl have shoulders F4 F4, which abut against corresponding shoulders on the ears F3, and limit swung away from each other. Said shoulders are soformed that the links can only be opened sufficiently' to permit the easy insertion of the The leaves are therefore kept abreast of each other--that is to Say, neither can be moved longitudinally ahead-of the other when the links areopened and the oil-cakes in place. The leaves are therefore obliged to move exactly alike when they are placed in the press-box, and each will exactly coincide with the other and reach tile inner end of the` press-box. This feature is very important, because if the leaves do not go back alike in the press-box the heavy press ure to which they are subjected will press them out sidewise and` Vdistort them, so that they will soon become useless.
The leaves of an oil-press mat have'lbeen before connected by links pivoted to the leaves and to a handle; but the links and the ears on the mats, to which the links are pivoted, have not been provided with shoulders, as ours are, the connection having been such that the leaves can move endwiseindependently ofeacli other, and are therefore liable to be improperly placed in the press-box.
Two oil-cakes inclosed, as usual, iin press cloths or bags may be placed between the frames A A. When pressure is applied the wire sheets, cloth sheets, and leather sheets coinbine to produce continuous channels for the escape of oil from all parts of the outer surfaces ot' the cakes, thereby greatly facilitating the yield of oil. The leather sheets, being somewhat yielding, prevent the powerful pressure employed from seriously injuring the press-cloths in which the cakes are inclosed, and obviate the liability of breaking the press, which exists when the mats are made ot' entirely rigid material. The cloth sheets interposed between the leather and wire make the mats more duralthe extent to which said links can be opened or IOO ble by equally protecting the leather and wire, as above stated, and also contribute to the elasticity of the mat. The rigid metal frames prevent the mat from stretching, so as to exceed thesp'ace allotted to it in the box ot' the press. The detachable connections Yof the leather sheets enable them to be readilyremoved when the mat becomes gumlned and become extended by use, so that they bear at their edges against the sides of the pressboxes in which the mats are placed.
It will be observed Ithat the numerous perforations of the wire-cloth sheets enable the fastenings D D to be passed through any desired parts of said sheets, so that as the leather sheets become laterally extended by constant pressure the points ot' enlargement of the fastenings D D with the wire-cloth may be changed from time to time to keep the leather in a smooth condition Without detrimentto the wirecloth.
We claim- 1. The improved oil-press mat composed ot the rigid frames A A, sheets B B, of wire-cloth, secured tosaid frames, and outer sheets, (l C, of leather, secured to the Wire-clothsheets, and the detachable fastenings D D, passed through the leather and the wire-cloth, the numerous perforations of the leather enabling said fastenings to be passed through different parts of the Wire-cloth without detriment to the leather, as s et forth.
2. The improved oil-press mat composed of the rigid frames AA, sheets B B, of wire-cloth, secured to said frames, sheets E, of textile fabric, laid upon the outer surfaces of the sheets B B, and leather sheets C C, laid upon the outer surfaces of the cloth sheets, and secured in place by detachable fastenings D D, passing through the leather, cloth, and Wire sheets, the fabric sheets E protecting both the Wire-cloth and the leather, while the leather and fabric sheets form a yielding backing, whereby the wire-cloth is prevented from injuring the presscloths, and a somewhat yielding character is imparted to the mat, as set forth.
3. In anoil-press mat, the leather sheets hav- F. C. MANN. HENRY SCHUMAGHER.
