I-IENRY L. HILDBETH, OF SAGINAW, MICHIGAN.
SALT-GRAINER.
SPECIFICATION forming part of Letters Patent No. 720,143, dated February 10, 1903.
Application filed September 18V, 1902. Serial No. 123,834. (No model.)
.To a/ZZ whom, it may concern.:
Beit known that I, HENRY L. HILDRETH, of Saginaw, county of Saginaw, State of Michigan, have invented an Improvement in Salt- Grainers, of which the following is a specification.
My invention has reference to salt-grainers; and it consists of certain improvements set forth in the following specification and shownin the accompanying drawings, which form a part thereof.
The object of my invention is to provide a construction of salt-grainer which shall embody simplicity, cheapness of construction, and durability.
In carrying out my invention I employ a long grainer-tank having an incline at the discharge end and combine therewith side guides on the sides and scraper devices comprising reciprocating chains or'cables, saddles or blocks clamped to the chains or cables at intervals in their length Within the grainer-tank, cross-bars connecting the saddles and having ends beyond .the saddles guided in the guides, and hinged scrapers pivoted or hinged to the saddles.
My invention also comprehends the said improvements further distinguished by the fact that the saddles are split and adjustably clamped upon the chains or cables to permit of proper relative adjustment of the several Scrapers.
My invention also comprehends details of construction which, together with the above features, will be better understood by reference to the drawings, in which- Figure 1 is a plan view of two grainers and the driving mechanism therefor embodying my invention. Fig. 2 is a sectional elevation of one of my improved grainers. Fig. 3 is a sectional elevation of a portion of same on a larger scale. Fig. 4 is across-section of same on line 4 4 of Fig. 2, and Fig. 5 is a perspective view of one of the saddles and the connecting parts. Fig. 6 is a sectional elevation ofthe front portion of a salt-grainer, showing a modification of my invention; and Fig. 7 is a side elevation of the saddles into the cross-rods and scraper in section, showing a modified form of this part of my invention.
A A are grainers, which are of the construction to be described in detail later on. These grainers have driving-shafts B for reciprocating the scrapers. These shafts B are each driven by sprocket wheel and chain gearing C from a counter-shaft D, and this counter-shaft in turn is driven first in one direction and then in another by a power-shaft F through sprocket Wheel and chain gearing E. This power-shaft is secured to a drivingpulley F3 and has also upon it two loose pulleys F F2. Belts G and G are adapted to rotate the pulley F3 in opposite directions and are driven by a drum G2, rotated by the engine G3. The belts G and G are shifted by belt-Shifters f and f', so that either belt may be alternately thrown upon the pulley F3 and in that manner alternately rotate the powershaft Fin opposite directions. `As the transmitting-gearing E and C produce a reduced speed, it is evident that the grainer-driviug shafts are rotated at slow speeds. Any num- .ber of grainers may be operated by the same counter-shaft D, if so desired.
Referring now to the grainers, as more fully shown in Figs. 2 to 5, inclusive, the tanks A' are provided with incline discharge ends A, up which the salt is scraped and discharged bythe Scrapers. The bottom of the tank is provided with steam-pipes H for evaporating the brine contained in the tanks to secure concentration and precipitation of the salt. I represents guides secured upon the sides of the tank near the bottom and incline and preferably consist of two angle-irons bolted to the side frames of the tank. LL are crossbars or tubes having their ends Zguided in the guides I, as shown in Fig. 4. Secured to these cross-bars adjacent to the respective guides are the saddles. These saddles are split vertically and by bolts j are clamped upon the endless chains or cables K, Which are guided about the wheels B2 B3 at the rear of the grainer-tank and driven by wheels B at the front of the tank secured upon the driving-shaft B. The opposite rotation of this shaft reciprocates the saddles and their crossbars in the guides I. Pivoted in the saddles by rods 'm are the grainer-scrapers M, which may be of metal and stiened by T-iron N, secured to the same and extending transversely across the tank. Stops O, extending down from the saddles J, act to limit-the back- IOO ward movement of the scrapers M, but allow them to swing in their backward movement so as to pass freely over the salt. In the forward movement the scrapers M are Vertical, as shown in Fig. 3, and push the salt forward. Thedistance apart of the saddles and their scrapers is proportional tothe distance it is desired they shall travel in their reciprocation, so that the space traversed by one scraper shall be overlapped by the space traversed by the adjacent Scrapers. In this manner the salt is conveyed forward in stages, one scraper after the other moving it forward toward and up the incline.
The two halves J J of the saddles .I are held in position by the rods L and permit any desirable relative adjustment in the length of the chains. The construction is simple andinexpensive. The several saddles being connected by the chains are caused to move simultaneously in the same direction and at the same speed. The special gearing employed enables the movement to be comparatively slow. Itis immaterial whether the reciprocations are caused to take place automatically or by hand manipulation of the shifters f f at proper intervals, as such details are immaterial to my invention.
While the saddles J may be split and adjustably clamped upon the chains or cables, (the latter being continuous,) as shown in Figs. 2 and 5, the saddles may be solid,if desired, and the chains or cables made in sections and suitably attached at their ends to the saddles. This is shown in Fig. 7, in which the chain ends K' are secured to screweyes K3, screwed into the ends of the saddle .I and through the transverse tubular bars L for strength and also to hold the saddle in proper position upon the bars. Any other manner of connecting the chains or cables with the saddles may be used.
In Fig. l I have shown one manner of reciprocating the chains K; butinstead of using a steam-engine and reversing-belt-driving mechanism I may employ a reciprocating engine, preferably hydraulic, as indicated at P in Fig. 6. To the ends of the piston-rod the chains K are connected. Any other suitable manner of imparting a reciprocating motion to the chains may be employed.
The heating steam-pipes H are shown in Figs. 2 to 4 as below the Scrapers, while in Fig. 6 I have shown them above, this latter location being perhaps the most satisfactory and economical from the practical standpoint. It is, however, immaterial to my invention what location is given to these steam-pipes.
While I have shown a chain as the connecting means between the saddles for driving 'them, it is evident that any other suitable means, preferably eXible, may be used instead. For instance, the chain may be substituted by a cable as a well-known mechanical equivalent.
While I prefer the construction shown, I
do not limit myself to the details thereof, as they may be modified without departing from the spirit of the invention.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
