Turpentine Filters.
No. 142,276. Patented August26,1873.
NITED STATES PATENT OFFICE.
FREDERICK Gr. RICHARDSON, OF BROOKLYN, NEVV- YORK.
IMPROVEMENT IN TURPENTINE-FILTERS.
Specification forming part of Letters Patent No. 142,276, dated August 26, 1873; application filed December 17, 1872.
To, all whom it may concern: v
Be it known that I, FREDERICK G. R1011- ARDSON, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Turpentine-Filters, of which the following is a specification:
In the manufacture and purification of turpentine and resin it is essential to filter the same in a melted, and consequently a hot,
condition through wire-cloth filters; and it has been universally experienced in practice that the filters ordinarily in use are, from faults inherent in their construction, fragile and quickly worn out, owing to incapacity to resist the severe usage to which they are necessarily subjected. With the woven-wire fabric heretofore employed for the purpose it is impossible to provide the requisite fineness of mesh or minuteness in the interstices of the filter to sufficiently strain the hot material without using wire wholly inadequate from its fineness to support the wear and tear brought to bear on it. To provide a remedy for the loss thus experienced in the production of marketable turpentine and resin is the object of this invention, which consists in a turpentine-filter, a new article of manufacture, constituted by the combination of a twilled wire-cloth straining-web and a circumferential rim, so applied as to hold the same in position against the weight or pressure of the liquid undergoing filtration, whereby the desired object is effectually secured.
Figure 1 is a plan view of a turpentine filter made according to my invention. Fig. 2 is a vertical transverse sectional view of the same. Fig. 3 is an enlarged view, showing the arrangement of the wires constituting the strainers medium in the filter.
A is the straining-web of the filter, made of any desired circumferential contour and formed of that special variety of wire-cloth which, from the peculiarities of" its structure, is known as twilled wire-cloth. In this the diameter of the wire of which it is composed I is much greater in proportion to the size of mesh or diameter of interstice than is the case with plain wire-cloth. Greater strength and durability to resist the specially-destructive action of the hot material upon the fabric is thus obtained when the straining web is made of this twilled wire fabric-never, before the the date of my invention, used for such purpose and having practically no superiority for any other filtering purpose over the plain wire-cloth preferred for straining cold and comparatively quick-flowing or limpid liquids.
Firmly fixed at its lower edge to the circumference of the web A, is the peripherical rim B, which, holding the said edges, supports and keeps extended the twilled wirecloth web A, while the same is subjected to strain while filtering melted .resin or turpentine, as hereinbefore explained, the increased diameter of the wire, as compared with the size of the mesh, enabling the same to resist with hitherto unusual efficiency the tensile strain exerted by the material while upon and passing through the filter, and affording a wider margin for the injurious effects of a high temperature upon the wire, and that involved in the expansion and contraction of the same by the variations through a wide range of temperature, involved in the practical use of the filter. This last advantage, furthermore, is greatly enhanced by the increased curve given to the wire at each intersection by the twilled character of the fabric, the said greater curves allowing the wire more readily to accommodate itself to the changes in length arising from the variations in temperaturev just set forth.
What I claim as my invention is- As a new article of manufacture, the turpentine-filter constituted by the combination of the twilled wire-cloth web A and the circumferential rim B, substantially as and for the purpose specified.
