Applicationnled-June20, 1917. `Serial-No. 175,949.

a To all whom-imag concern; 4 A Be itz-known that I, M'IQHAELB..` GREEN a citizen lof. the,- United States, residing at.

Memphis, in the county of Shelby and `State of Tennessee, have invented new and useful Improvements in Oil-Presses, of which the following is al specification.

This invention relates tooil pressesy and. it.

consists in the, novel features hereinafter, described and claimed.`

y An object of the invention is to provide an improvedystructure overthose shown in my,y earl-ierPatents'No. 11,061,837., issued May 13,y 1913, Aand 1,081,905, issuedDecember-.1-6,

1913, and over the structure shown in my ypend-ingl application Sen No 88,903.

-In the present. structure thepresscomprises top -andbottom blocks connected vtogether by means of ner and provided with -aV plunger or follower adapted -tobel actuated; by liquid, in the usual manner. Columnsare connected at. their ends with the top and bottom blocks and compression bars are provided with guides adapted to move. along jthe sai-d columns.

Some of thesaid bars areprovided atlth'eir upper vsideswith flanges having recesses adapted ato' receivevha-ir mats and vdrain perforations; or openings and plates are slidably mounted with relation to each set of bars. y Lever mechanisms arev 'ofpferaitively'f;` cnnected'with some of the upper plates and also operatively connected withV the lower` pl'ate` wherebyfthefsaid lower plate may be moved in an upward direction at a faster rate of speed than the upper plate in consequence of being subjected to pressure from the plunger. The bars are provided with suitable grooves whereby the oil which is squeezed from the lmaterial located between the sets of bars mav drain and drip upon the upper surface of the plunger.

In the accompanying drawings Figure 1 is an end elevation of the press with parts in section showing the kplunger in its lowest position;

Fig. 2 is a similar view showing the plunger in an elevated position;

Fig. 3 is a fragmentary side elevation of the press viewing the. same at a right angle to the illustration shown in Fig. l;

Fig. 4L is afragmentary horizontal sec-l tional view of the press cut on the line dof Fig. 1.;

bolts in the usualman--4 pass through the saidflan ges and` communicate 1 with the said` recesses.l The said barsare-arranged in sets Fig. 5 is a detailed sectional viewthrough the intermediate portion of a set bars' used: in the press.k

Y The,-presscomprisesa top 'or head block 1 and-a bottom .block Qccnnected together by means of bolts 3Y in the usual manner. plunger 4 is inovably mounted abovethe bottom 'block2 and may be actuated by oil or any suitable liquid under pressure in the usual manner. Columns 5 are secured 'at their ends to the top and bottoni blocks.-

Bars 6 are arranged in sets and the outer bars of each set areprovided at their edges with guides 7 which slidably receive the colf' umns 5. vThe bars G are provided with grooves-8 whereby; the liquid which Vis squeezed from the material placed between the -sets ofbars may drain from thesame. A filler 10 is mounted at the lower surface ofy the top or yhead block 1 and is adaptedtocooperate with the upper set ofbars 6.y

The outer bars G of eachk set areprovided at `their upper sides with flanges 11 havingy recesses 9 adapted to receive hair mats 12. The-flanges are further provided withopen-v ingsy lwhich V,communicate at their inner ends with the recesses 9 and serve Ias-means whereby the foil' or liquid mayV drain from between the sets .of bars. y

Hangers 15 are provided at their upper ends with slots 16 which receive bolts 17 attached to the edges 'of the top or head block 1. The said hangers are attached at. their lower ends to the `outer bars G of theupper set of bars.

Plates L0 areslidablyfmonnted atcthe .ends

of each set of bars G. The said plates are provided with flanges Q1 having slots 9.2 which receive pins 23 carried by the outer bars 6 of each set of bars except the lowest set. The plates 20 except the lowest plates are provided with legs Qd and the legs of the upper plates are attached to the outer bars 6 of the next lower set of bars. T he plates 20 are further provided with openings 25. The legs of the plates Q0 adjacent the ends of the third set of bars 6 from the bottom of the press are provided with extensions 20 which are pivoted to the outer ends of levers 2 fulcrumed at the ends of the outer bars 6 of the lowest set of bars. The inner ends of the levers Q7 are pivoted to the end portions of the lowest plate '20. As illustrated in Figs. 1 and 2, the pivotal connections between the levers 2 7 and the lowest plate 20 and the leg extensions 26 are .sor

placed'between the adjacent sets of bars 6 and the plunger 4 is caused to move in an 1 Yupwardv direction whereby the lower boxes approach the upper boxes successivelyfas the weight or support of the'boxes and meal or Y contents is transferred from the pins 23to a pressure on the lower box` orplunger; This process continues until all of tlieweight of the boxes and contents has been removed from the pins 17 at which time the contin-` uation of the rise ofthe plunger 4 takes up tlieiveiglit of the head block and then puts tension in theY bolts 3. It is during the movement of the plunger 4 before the entire weight is rremoved from tliepins 17 that the chief and important motion of the end plates v-QO'takes place. This pressure causes the oil to ooze from the said' material andthe oil drainsfrom the bars througli'the grooves 8 and the openings 13 and rims down into the upper portion of the plunger 4 inthe'usualV Y manner. As 'the lowest set yof bars 6 of the series of sets is forcedv up closer toward the lnext set above the leg extensions v26 Vcause the levers 27' toswing on their pivotal connection withftlie bars whereby'the lowestplatesrQOai-e moved in an upward direction at afaster rate of speed than the upper plates 20 andV this confines the material between the two lower sets of bars aiide'ffectu- `ally squeezes or presses Vall of the oil outI 0f the same. f

l'From the foregoing descriptionv taken in,

conjunction with the accompanying drawing, it will be seen that van oil press oi simpleand durable structure is provided and that the same may be used econoniically'toV advantage'for squeezing the oil from inaterial, as for instance, cotton seedl and that coplas ot this patent may be obtained for the #said oil isi-'permitted to draiiilfrom the Ybars intothe plunger where it is collected vand maybe reniovedfrom the same at desired intervals.v 1
