FRANK B. ANDERSON, OF CLEVELAND, OHIO, ASSIGNOR TO THE V. D. ANDERSON COM- PANY, F CLEVELAND, OHIO, A CORPORATION OF OHIO.

TEMPERING APPARATUS FOR OIL-BEARING MATERIALS.

Application filed July 26,

This invention pertains to a moisture feeding device for tempering apparatus, and more specifically to means employed to feed the required amount of water to material which is passed into and through a tempering apparatus and therein treated preparatory to its being fed to a suitable expressing apparatus or press wherein it is subjected to an expressing action to remove the oil and moisture content.

In the treatment of certain materials for the purpose of expressing oil or grease therefrom, it is essential that the material con tain moisture, for otherwise the material will not give up the oil as freely as desired and the cake which passes from the apparatus will not be oil free or substantially so.

The apparatus is especially designed to be used in conjunction with the so-called Anderson expeller, as depicted in Letters Patent 829,315, Anderson, dated August 21, 1906, though, of course, its use is not limited to such a type of press.

A simple embodiment of the invention is shown in the accompanying drawings where- 1n Fig. 1 is an end elevation, partly in section, of the combined water feeding mechanism and tempering apparatus;

Fig. 2 a side elevation thereof, the parts broken away so as to more clearly show the construction Fig. 3 a top plan View of the trough from which the water is removed in measured quantities and fed to the tempering device;

Fig. 1 a vertical sectional view thereof, taken on the line IV-IV of Fig. 3;

Fig. 5 a vertical sectional view of the water trough, the measuring wheel and its allied parts, the section being taken on the line VV of Fig. 1; and

Fig. 6 a similar view taken on the line VI-VI of Fig. 5.

In the drawings, 1 indicates so much of a tempering apparatus as is necessary to an understanding of the invention, said apparatus having, as illustrated, the form of a trough provided with an exteriorly located jacket 2 between which and the body of the trough, steam is interposed for the purpose of heating the same. Extending through the trough is a shaft 3, upon which is mounted a series of interconnected collars or sleeves 4 carrying stirring or propeller blades 5 which agitate the material and tend 1922. Serial No. 577,710.

to feed it from the intake end, which is that portion which is illustrated, toward the discharge end and into a press such as is shown in the Anderson patent above referred to, or to any other suitable expressing means.

Secured to the frame of the tempering apparatus is an upwardly extending bracket 6 which forms the support for a water reservoir or chamber indicated generally by the numeral 7 Said reservoir is open at its up per side, and is provided with a longitudinally extending upstanding partition or wall 8, and two transversely extending short walls or dams 9 and 10. There is thus produced within the reservoir by said walls or parti tions just referred to, and the outer walls of the reservoir proper, a main water supply chamber 11, a second chamber 12, into which the measured quantity of water is deposited by the water wheel hereinafter referred to, a discharge chamber 13, which is in communication with the tempering apparatus as herein set forth, and an overflow or outlet chamber 14 for any excess of water. A sup ply pipe 15 (Figs. 1 and 6) opens into the lower portion of the main water supply chamber 11, and the water is maintained in said chamber at a predetermined height by the dam 10, any excess flowing over the dam and down through the short pipe or nipple 16 which terminates in the upper portion of a sight discharge casting 17, from which leads a pipe 18 to the sewer or a reservoir in which the excess water may be collected. The said discharge casting, as will be best seen upon reference to Figs. 2 and 6, is open at one side so that the attendant may see that the prOper amount of water is within the main water supply chamber 11, this being determined by the passage of the water from the lower end of the nipple 16 and the dropping thereof through space into the lower portion of the casting 17 The water in measured quantities is deposited into the chamber or trough 12 in a manner shortly to be described, and passes over the dam 9, which is lower than the longitudinal partition 8, into the discharge chamber 13, through the nipple 19 which is in communication with the lower portion of said chamber 13, said nipple terminating in the upper portion of a sight feed casting 20 (see Fig. 2) which is open at one side so that the operator may, when standing on the floor, readily determine if the proper feed is being effected. A pipe 21 opens from i the lower portion of this sight feed device 20 and conveys the water into the upper portion of the tempering apparatus 1.

Mounted within a bearing 22 formed upon the upper portion of the outer wall of the reservoir 7, is a shaft 23. To the inner end of the shaft there is secured a measuring device for the water, comprising a wheel having a series of pockets or buckets 2% equally spaced about its axis, each bucket having a mouth at the outer end thereof, which, as the wheel is rotated, dips into the water in the main water supply chamber 11, each bucket likewise having an opening, as 26 (see Fig. 5) at the inner portion thereof, the inner wall. of the mouth of each bucket forming a part of a frustro-conical hub extension 27. Secured to the outer face of the wheel is a funnel shaped delivering element 28 having a central cone 29, the base of.

which abuts the outer end of the hub sect-ion 27 so that said elements 27 and 29 form, in effect, a cone, and the openings 26 extending from the pockets likewise communicate with passages formed in the funnel shaped member 28by ribs or partitions 30 extending radially therein, sothat the water which is picked up by each of-the pockets will be discharged when that particular pocket reaches its uppermost position, and will pass therefrom into the measuring chamber 12 and thence over the dam 9 down through the sight feed member 20 and through the pipe 21 to the tempering apparatus.

It is designed to have the water wheel work in timed relation with the paddle niieeha-nism or otherfeeding device located within the tempering apparatus, and to this end the following mechanism may be employed:

Secured to the outer end of the'shaft 28 is a gear 31 'which in turn meshes with a pinion 32 shown as formed upon the outer end of a stub shaft 33, the latter being supported in a bearing 3% formed as a part of the reservoir 7. The shaft 33 has swiveled thereon a rocker element comprising a hub 85, from which there extends upwardly an arm 36 to which is pivoted a pawl 37 adapted to engage the teeth of a ratchet wheel 38 secured to the shaft 33. A downwardly extending lug or extension 39 is formed integral with the hub and a rod or arm a0 is securely fastened therein and extends outwardly and downwardly therefrom. Secured to a bracket ll extending downwardly from the bearing 34, is a gravitating locking"- pawl 42 which engages the ratchet wheel 38 and prevents retrograde movement thereof. Secured to the outer end of the shaft 3 is a crank 43, the pin l i whereof is connected to one end of a pitman t5, the other end of which is secured to a block 46 through. which the rod extends. The

block i6 is adjustably mounted on the rod 40 and may be moved up and down thereon and held in its adjusted position through a clamping screw 17; Thus by moving the block along the rod and securing it in its adjusted position the rocker carrying the actuating pawl 36 will have imparted thereto a greater or less throw with the co sequence that a greater or less number of revolutions will be imparted to the water measuring wheel for each revolution of the shaft 3, so that a greater or less quantity of water will be fed to the tempering apparatus under such conditions. Thus by a simple adjustment of the block 46 with reference to the rod 40, a greater or less amount of water may be accurately fed to the temperin a )pa-ratus, according to the needs of the material passing therethrough.

Preferably a cover 48 will be placed over the water wheel and its allied parts, the same being hinged about a bracket 49 provided with an outward extension 50 upon which the cover may come to rest when it is thrown upwardly and to one side.

It is thought thatthe operation of the device is clear from the above description and therefore a detailed exposition of the operation is not deemed necessary.
