CONTINUOUS OIL-PRESS.

Specification of Letters Patent.

Application led May 1, 1911.

To all whom it'mwy concern:

Be it known that4 we, FRANK A. BLAIN and CLYVE D. HELM, citizens of the United States, residing at Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Continuous Oil-Presses, of which the following is a specication.

This invention relates to oil presses and more particularly to roller presses which are provided with a continuous feed, and the object is to provide presses for extracting oil from such material as cotton seed, linseed, pea-nuts and other nuts, beans, grains, and to press juices yfrom fruits, and to provide presses which have a continuous feed which is accomplished mechanically and which press the oil or juice from the material by means of endless traveling aprons or chain belts. With such presses the large force of laborers who are usually employed for preparing the material for the presses is dispensed with as well as the danger to such employees and the pressing is done in much less time than is required where the material is prepared manually for the presses. The feeding is continuous and the pressing is continuous. l

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application and specification.

Figure 1 is a side elevation of the press. Fig. 2 is a cross-section taken on the line x of Fig. 1. Fig. 3 is a portion of the lower compression rollers and the gearing for driving the same, shown in a diagrammatic plan view. Fig. 4 is a plan view of a portion of the lower apron or chain belt. Fig. 5 is a vertical cross-section of the traveling aprons or chain belts. Fig. 6 is.a side elevation of a portion of the lower traveling apron.

Similar characters of reference are used to indicate the samerparts throughout the several views.

The improved press is provided with a frame consisting of pedestalsV 1 and lower side bars 2 and upper side bars 3. The upper beams 3 and the lower beams 2 are held in operative relation by the tie bars 4 and 5 with suitable nuts 6 and caps 7.

The beams 2 are held properly spaced by tie rods 8. The beams or bars 2 and 3 are set at an incline, as shown in Fig. 2, so that the oil will not follow the pressed cake out of the machine, but escape downwardly into a pan or receiver 54 whence it may be drawn off through a cock 55. The material to be pressed is carried by chain belts or aprons hereinafter described and the chains can be made to run more or less closely'v together by caps 7 and nuts rand the vchain belts will be made to approach each other more closely toward the delivery end of the machine so that the pressing will be done progressively.

Lower compression rollers 9, 10, and 11 are journaled in fixed bearings 12 attached to beams 2 and these rollers have cogs 13 on each vend thereof which mesh with pinions 14 which are provided with bearings 15 attached to beams 12. A is providedfor the rollers 9, 10, and 11. A power pulley or drive wheel 16 is fixedly mounted on a power shaft 17. A pinion 18 is rigid with wheel 16 and drives a cog wheel 19,. A pinion 20' is rigid with the'cog wheel 19 and the cog wheel 19 and the pinion 20 are rigid with shaft 21. Pinion 2O drives a cog wheel 22 and cog wheel 22 drives a pinion 23 which is rigid therewith. The pinion 23 and cog wheel 22 are loosely mounted on the shaft 24.l Pinion 23 drives a cog wheel 25 which is rigid with shaft 26. The shaft 2 6 drives pinion 14 and pinion 14 drives cog wheels 13 which drive rollers 10 and 11. Cog wheel 13 of roller 10 drives pinion 14 and pinion 14 drives cog wheel 13 and roller 9.

A traveling apron or chain belt 27 is driven by the cog wheels 13 and by a drum 28, the drum 28 being driven by the shaft 17. An idle drum 29 is mounted on a shaft 30 to support the chain belt 27 at the receiving end of the machine. The chain is moved continuously during operation over the rollers 9, 10, and 11. The chain belt 27 is constructed to form a bed for receiving material and holding the same' thereon while the material is being pressed by the rollers. The chain is constructed of bars 32 which are dovetailed into each other and the dovetailed portions are hingedly connected together by rods 31. The outer ends of the bars have upwardly projecting flanges 32 to form sides of the apron to prevent escape of material laterally. Cog teeth 33 positive drive form racks on each side of the chain belt to be engaged by the cog wheels 13 whereby the chain belt is driven. The oil or juice will escape downwardly through the joints of the bars which form the chain belt. A sheet of camels hair cloth 34 may be spread on the chain 27 for better straining of the oil or juice.

Rollers 35, 36, and 37 similar to rollers 9, l0, and l1 are mounted above the rollers 9, 10, and 1l for compressing material which is being carried on chain 27. These rollers are journaled in bearings 38 which are fixed on beams 3. Means are provided for driving these rollers positively. Roller 37 is driven from the shaft 24 by means of spur gear wheels 39 and 40. The rollers 35, 36, and 37 each have cog wheels 41 formed on each end thereof, and pinions 42 mesh with these cog wheels, so that the series of gearing may be driven from shaft 43. The cog wheels 41 drive a chain 45, similar to chain 27. Idle drums 46 are mounted on the beams 3 by bearings 38 for maintaining the position of thc chain 45 during operation. The chain- 45 has racks 47 on the sides thereof to be engaged by the cog wheels 4l. The parts of the chains 27 and 45 adjacent to each other run substantially in the same direction. A sheet of camels hair cloth 50 may be placed under the chain 45.

Means are provided for applying pressure to the rollers and consequently to the chains 27 and 45. A hydraulic cylinder 43 is mounted above the beams 3 for pressing thereon. A piston 49 operates in the cylinder 48. The hydraulic pressure will take effect also on the cap 7 and the consequence is that the beams 2 and the beams 3 are drawn toward each other, and chains 27 and 45 are pressed toward each other.

Material 50 is fed to the chains 27 and 45 through a hopper 51 and chute 52 to the lower chain belt 27. The oil or juice is pressed out of the material during its passage between the chains. The pressed cake 53 is delivered in sheets by the chain belts 27 and 45 and may be gathered in any suitable manner. Additional idle drums 54 may be placed between the compression rollers to support traveling aprons 27 and 45. An agitator 55 may be used in the hopper 5l to aid in distributing stock to the apron 27.

Having fully described our invention, what we claim as new and desire to secure by Letters Patent, is,-
