"UNITED STATES PATENT OFFICE.
S. G. RICE, OF ALBANY, NEW YORK.
SNUFF-SIFTER.
Specification forming part of Letters Patent No. 44,9711, dated November S, 1864.
To all uhom 'it may concern Be it known that I, S. G. RICE, of the city and county of Albany, and State of New York, have invented a new and useful Improvement in Snnft' Disintegrators and Sitters; and [do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a top view of my invention. Fig. 2 is alongitudinal section ot' the same. Fig. 3 is a ltransverse section of the saine.
The same lettersof reference in the several figures indicate corresponding parts.
The main object of-my invention is to sift snuff that has been dampened or moistened by the scentin g-liquid that is used in its manufacture 5 but it may also be usefully employed for sifting anything-for which a sieve is used, more particularly pulverized substances which have from moisture or dampness assumed a lumpy form in their removal from one vessel or receiver into another.
My invention consists in the combination with a screening-sieve of a free breaker in such manner that the breaker vibrates and acts with a sliding or both a sliding and rolling friction upon the screening-surface of the sieve, and in thus operating causes the particles of snuff or other substances to be disintegrated, and also facilitates the passage of the same through the meshes of the screen.
To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings.
A designates an ordinary rectangular sieve or screen. It may be vibrated by hand or by gearing, as deemed preferable.
B is a breaker formed of longitudinal and transverse bars c a, and b b b b. This breaker in its transverse section on its under sidemay be the segment of a circle, so as to roll or rock in a direction. at right angles to that in which it traverses the screen. The length oi the breaker should be much less than that of the screen or sieve box, in order that it may have sufficient traverse on the sieve to produce the desired result. It may also be somewhat So far as the longitudinal traverse is concerned, it is important that the amount of play allowed the breaker should be as great, if not greater, than the distance between each pair of transverse bars. By preserving these proportions the whole surface of the sieve or screen will be acted upon by the several transverse bars during each vibration of the breaker.
By examining the drawingsit will be seen that the breaker is arranged upon the sieve or screening surface and is free of all suspending connections, and therefore,when the sievebox is vibrated or tossed back and forward, it will also receive a similar motion, and, it being shorter than the sieve, will slide with a frictional contact upon the screeningsurface until it is arrested by the ends of the sievebox. It also will have a slight lateral movement as it traverses the sieve longitudinally, and in some instances it may roll back and forth toward the sides of the sieve-box. These actions ot the breaker cause the accumulated particles of snuff or other pulverized substance te be disintegrated and the passage of the same through the screen to be facilitated. Further than this, the breaker causes the scent to be diffused more generally throughout the snuff. And fin-all y, the brea-ker keeps the meshes ot' the screen free and open, its frictional contact and concussive force ef fecting this result.
I have found in practice that the same quantity and a better quality of snuff can be made77 or sifted iu twenty minutes by one person with my improved sieve or screen as could be made in the old way in a whole day and with the attendance of two persons.
I deem it necessary for my protection to say that while I have particularly described one style of breaker, and which I believe the best for the purpose named., I do not limit myself to this particular form, as many equivalent forms of free7 breakers maybe adopted and the same operate on the same general principle set forth.
What I claim as my invention, and desire to secure by Letters Patent, is-
l. The combination of a free breaker with a screen or sieve, substantially as and for the purpose set forth.
2. The constructing of the free breaker of longitudinal and transverse bars in such main ner that in its Vibration over the screeningsurface the whole of such surface shall be treversed, substantially as described.
3. Constructing the free breaker of segment form on its under side in a transverse direction, substantially es and for the purpose set forth.
4. So constructing a. free breaker and using it in a vibmtable sieve or screen that it will traverse the screen longitudinally and laterally and also rock or roll transversely, substantially as set forth.
