To all whom it may concern: p v

Be it known that we, EUGENE l ROBERTS and ANGUs H. GIBSON, citizens of the United States, and residents of Lehi, in the county triugal Machines, of which vthe following is a specification.

Our invention 1s an improvement incen.`

trifugal machines, and consists in certain novel constructions and combinations of parts hereinafter described and claimed.

The object of the invention is to provide a machine of the class".specii'ied, wherein means is provided for thoroughly cleaning the inner surface of the basket, and which and without injury to the basket or the may be swung over the basket, lowered thereinto, and withdrawn and swung away from over the basket aiter the basket is cleaned.

A urther object is-toso arrange the said cleaning means that the incrusted sugar or other material may be cut away gradually,

cleaning means and without possibility of injury to the operator. l

Referring to the drawings forming a part hereof-Figure 1 is a section through a portion oi the casing ofa centrifugal'machine provided with our improvement; Fig. 2 is a view at right angles to Fig. 1; 'Figl 3 is a plan view; Fig. 4 'is a vertical section through the hollow shait; Fig.`5 is a sectionat right angles to Fig. 4; and Fig. 6 is a sectional view of the paddle mounting.

The present embodiment of our invention is supported by a hollow bearing bracket 1, comprising a vertical portion 2, andaphorizontal portion 3, having at the inner end thereof a` vertical sleeve 5. |The vertical portion of the bracket 2 has its lower end reduced as at 6, a shoulder 7 being arranged `betvv'een the reduced portionand the main portion, and the reduced portion is received in abearingB, which is provided with a lbase 9 secured by bolts 10, to the sidect the casing 11. A nut 12 is threaded on to the lower end of the reduced portion of the bracket, for securing the bracket in place. i

A shaft 13 is journaled in the horizontal portion of the bearing, the end of the shaft adjacent to the sleeve 5 being provided with a 'pinion 14, keyed thereto by akey 4, and the other end with a hand wheel `15 for convenience in manipulating the shaft. A

i hollow shaft '16 is slidable in the sleeve 5,

and one side of the shaft is provided with rack teeth'l?, with'which the pinion 14 l meshes of Utah and State of Utah, have made certain new and useful Improvements .in Cen- A. 'rod is is jburnned in the hollow shaft,

the upper end of the rod being reduced as 'i at 19, and passing through an opening in a collar20, which has projectingtherefrom a lever 21. The lower side of the collar'20 rests on 'the top of the hollow shaft, and

a nut 22 is threaded'l on to the lupper end of the rod, to retain the collar in place. A

key 23is provided on the reduced portionV of thevrod, the said key engaging-akeyway vin the'collar as shown'in Fig. 4, to constrain the rod to move with the lever 21.

The lower end of the. rod v18,"is providedM with a key v24, engaging a-keyway inv'a' bearing 25, and the bearing is secured 1n place on the rod by a'n'ut 26. l VThe bearing is provided with oppositelyxextending lat-` 'y

eral arms

27, 27, the said arms 'forming' a continuousv arc tts/shown in Fig. 3. u The arm 27 is enlarged at its end as shown at 28, and is provided with a socket 29, for receiving the end of a .wooden paddle 30',

which is secured in the socket by boltslf.

soi

The outer end of the paddle is beveied'- as i shown'at '32 in Fig. ,6, so that when thearm lis swung into' position with the end of l' the paddle "against vthe inner wall of the basket or` screen 33, the beveled 'end will fit' the inner face ofthe said wall.

The upper end of the sleeve 5 is provided e0 with an annular rib 34, having at opposite sides outwardly projecting pins 35, A cap i I 36 is mounted on the upper end of, the bear ing inclosin-g the rib, and the sidewalls of the cap are slotted as shown at 37 to receive theA pins. vThe cap is also provided with a central opening through which passes the .i

sleeve 16 and rod 18,'and a plurality of coil springs 38,'is arrangedbetween the cap and' the upper iace of the rib. VAn arm 39 ,is

secured to the top40 of the casing, by bolts y 41, and a roller 42 is journaled betweenthe. arms 43ofva fork on the end of the arm, and

engages the sleeve 16` in its raising and low# ering movement, toreduce the friction.- The 165' cap is engaged by a collari44, on the'sleeve 16, `below the bearing 20, and prevents vbreakage or injury to the parts when the bearing is at its Il owest point. The springs yield when the collar 44 engages the cap,

ally checking the descent without jar.

n permitting the cap. to descend, and g1-adn;

Our invention is especially adapted for use in centrifugal. machines used in sugar making, and the operation is as follows: it is desired ugal machine the hollow shaft being elevated, the bracket is swung so that the horizontal portion thereof projects over the casing. The hand wheel is now turned to lower the hollow shaft through the ope ing 45 in the top of the casing, after which the lever 2.1 is turned to bring the paddle into the position shown in F ig. 3 in dotted lines. During the'lowering of the paddle into the casing, the said paddle occupies the position shown in full lines in the said figure. When in the position shown in dotted lines, the beveled end of the paddle engages the incrustation of material on the inner face the screen, and strips oil a portion thereof according to the width of the paddle. The hand wheel is turned slowly with the paddle in this position, gradually lowering the paddle and stripping the incrustation as it is lowered. Just before the paddle reaches the bottom of the screen the collar v44 engages the cap, and the movement is gradually checked. After the sugar is loosened, the lever is operated to swing the paddle into the position shown in Fig. 3, and the hand wheel is rotated to elevate the paddle from the casing, after which the bracket may be swung to the side of the casing entirely out of the way.
