WILLIAM M. MGKENZIE, OF DORCI-IESTER CENTER, MASSACHUSETTS.

SEPARATOR.

Application filed March 29, 1913.

To zZZ whom it may concern:

Be it known that I, WILLIAM M. MCKEN- zin, a citizen of the United States, residing at Dorchester Center, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Separators, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to separators especially adapted to be used for separating screw machine products from chips after the oil has been extracted therefrom; the object being to provide a separator which is so constructed that the finished products can be quickly separated from the shavings without handling the same, thereby overcoming the difiiculties now existing in separating the products from screw machines.

Another object of the invention is to provide a separator in which an air blast is employed for separating the shavings from the articles produced on the screw machine wherein the shavings and articles are placed in a receiving box from which they are forced onto a shaker for distributing the same, which is provided with a reticulated lower end allowing` the air blast to act partly upon the shavings and articles before they are discharged therefrom, whereby the lighter articles will be blown from off of the reticulated shaker and out of the falling mass of articles into another portion of the separator from which they are discharged into a suitable receptacle; the finished articles or products being discharged at another point from the separator.

Another object of the invention is to provide a separator which is provided with means for regulating the air blast in accord ance to the nature of the products being separated; the separator having a sight opening through which the operator can watch the separating action of the air blast upon the products and thereby regulate the same in order to prevent too heavy a blast which would cause the finished products to be blown with the shavings into the receiving compartment.

Another and further object of the invention, is to provide the separator with `a finished product-receiving trough having a bot- A tom formed of wood or other soft material in order to prevent the finished products from being injured by the impact therewith in falling from the shaker.

Specification of Letters Patent.

Patented Jan., 26, 1915.. serial No. 757,636.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

ln the drawings-Figure.1, is a side elevation of my improved separator partly broken away, showing the interior construction of the shaker and product-receiving trough; and Fig. 2, is a top plan of the separator.

Like numerals of reference refer to like parts in the several figures of the drawings.

1n the drawing, 1 indicates a suitable base upon one end of which is mounted a casing 2 having an extended portion 3 forming a compartment for receiving the shavings and like articles of the material placed in the separator, as will be later described. rlhe extension 3 is provided with a reticuiated end 4f and top portion 5 forming an exnaust for the air and the lower end of said extension forms a receptacle which is provided with a suitable discharge opening, not shown, through which the shavings are adapted to pass and be caught by a suitable receptacle, not shown.

The casing 2 is provided with a productreceiving trough 6 having a wooden bottom 7 inclined as shown. said trough being an extension of an air blast Hue 8 and separated therefrom by a reticulated partition 9. as clearly shown, for preventing the finished products from passing into the same over the outlet 10 which is provided with a discharge opening 11 through which the finished products are adapted to be discharged.

Extending into the casing 2 above the flue 8 is a shaker 12 provided with a closed top portion 13 and a reticulated lower end 14 which extends over the receiving trough 6; said shaker being provided with transverse rods 15 mounted upon grooved rollers 16 in order to allow the same to be reciprocated easily in order to distribute the products and shavings over the bottom of the shaker so that when they are discharged from the lower end the air blast will be allowed to have full force upon the same, as will be later described.

The base l is provided with standards 17 at its opposite end supporting a receiving box 18 having a discharge chute 19 extending into the shaker 12. as clearly shown in F ig. 1, through which the shavings and products are adapted to be forced manually but of course, it is understood that various forms of receiving and distributing receptacles could be employed for mechanically discharging the contents into the shaker.

Mounted on the base l between the uprights 17 is a blower 2O provided with a discharge 21 connected to the flue S by a coupling 22 which is provided with a reciproeating valve 23 to which is connected an operating rod 24; the upper end of which has a pivotal connection with an arm 25 fixed on a shaft 26 mounted in suitable depending brackets depending from the boX 18. lThe shaft 26 at one end, is provided with a lever 27 having a hand lever 2S carrying a pin 29 adapted to co-act with a number of openings L 30 of a plate 31 fixed on the side of the box 1S by means of which the lever 27 can be locked in its adjusted position, whereby the adjusted position of the valve can be maintained. It will be seen by this construction, that the air blast can be regulated by operating the valve through the mechanism hereinbefore fully set forth so as to adjust the air pressure according to the kind of products being separated.

The blower 20 is provided with a fan shaft 33 having a drive pulley 34 at one end, which can be driven by a belt extending from a power shaft, not shown, or the same can be driven directly from a motor. However, the manner of driving this shaft forms no part of my invention.

Mounted in suitable bearings, not shown, is a drive shaft which is driven by a twisted belt 36 passing over a pulley 37 carried by the shaft 33 and a pulley 88 carried by the shaft 35, the pulley 37 having a smaller diameter than the pulley 38 in order to reduce the speed of the shaft 35. -The shaft 35 is provided with a pulley 39 carrying a belt 40 which extends transversely and passes over a pulley 41 carried by a counter shaft 42 mounted in suitable bearings 43 and 44 carried respectively by the casing 2 and standard 17. The end of the shaft 42 is provided with a crank 45 carrying a wrist-.

pin 4G on which 1s mounted a pitman-rod 47; the free end of which is pivotally connected to a depending bracket 48 carried by the shaker 12. From the above, it will be seen that through the medium of the counter-shaft and driving connections, the speed of the drive shaft is reduced in order to prevent the shaker from being operated at an excess rate of speed.

The casing 2 is provided with a sight opening 49 in a hinged door 50 above the shaker, and the casing is provided with a light-receiving basket 51 in which an incandescent lamp is adapted to be placed in order to illuminate the inside of the casing so that the operator can inspect the separation so as to adjust the valve to regulate the air blast according to the material being.

separated.

The operation of carrying out the separation with a machine as set forth, is as follows: The products and shavings are placed in the box and the operator forces the same into the shaker, it of course being understood that the fan of the blower is being driven and that the shaker is being reciprocated simultaneously through the medium of the belts and pulleys and as the products are deposited upon the shaker by the reciprocation thereof, they are distributed and by the inclination of the shaker gradually work to the lo'wer end upon the reticulated portion, at which point they are subjected to the air blast which blows the lighter particles or shavings into the receiving chamber; the particles failing to be lifted by the air blast, are then discharged from the shaker where they are subjected to the full blast of air and all of the lighter particles which have not previously been removed are blown to the upper portion of the casing and drop into the shaving-receiving compartment. The heavy particles of value, such as the finished products, drop into the inclined trough 6 upon the cushioned bottom 7 and by gravity, are discharged through the outlet 10 and discharge opening 11 into the suitable receptacles. As the separation is being carried out, the operator can watch the same through the sight opening 49 and regulate the air blast by adjusting the valve.
