SUGABrCUTTING ATTACHMENT FOR SUGAR-CENTRIFUGALS.

To all whom it may concern:

Be it known that I, Gnoncn Vrvns, a citizen of the United States, residingat Thibodauiz, in the parish of Lafourche and State of- Louisiana, have invented anew and useful Sugar-Cutting Attachment "for Sugar- Centrifugals, of which the following is a specification.-

The present invention relates to improvements in cutting attachments for sugar centrifugals, and the primary object of this invention is the provision of a device adapted to be normally held in the position. to be 'moved vertically within and adjacent to the peripheral walls of a sugar centrifugal, and by means of a .spring actuatedrod to have a cutting tool disposed against the wall, to remove the crusted sugar therefrom during 'the rotation of the centrifugal receptacle.

A further object of this invention is the provision of a cutting device adapted to be attached to a centrifugal supporting frame and be moved vertically into and out of the centrifugal receptacle, the same being a shaft having mounted upon its lower end a cutting or scraping tool which normally exerts a tension to engage the inner peripheral wall of the receptacle in combination with a weight actuated means for moving said cutting or scraping tool or rod vertically up and down within the receptacle.

- A still further object of the invention is the provision of means for looking the cutting or scraping device out of engagement with the wall of the centrifugal receptacle, and yet in such a position to be readily placed in operable relation thereto when desired.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the .drawings-Figure 1 is a vertical central sectional view through a centrifugal and frame, showing the scraping device in operable relation thereto,- the same being shown in dottedlines when operating near the bottom or lower portion of the walls thereof. Fig.2 is an enlarged detail top elevation of the cutting blade and operating being understood that Specification of Letters Patent. Patented Dem 2 6, 1911, Application filed August 12, 1911.

mechanism showing a portion of the receptacle and supporting platform. Fig. 3 is a detailed perspective view of the cutting and scraping blade with a portion of its carrying rod adjacent thereto. Fig. 4. is a cross .section through the main shaft showing. the

mounting of the spring thereupon.

Referring to the drawings, thenumera-l 1 designates: the .main frame, platform 2 adjacent to the mouth of the centrifugal sugar receptacle 1, which is operably connected tothe vertical shaft 3 in the carrying the usual manner, the upperend' thereof being ournaled in the transverse plate or beam 5, 7

to which is connected thesuper-structure 6 of the present invention.

Connected to the rim 7 and also upon one side and the upper side of the platform 2 as clearly shown in Fig. 1 is a loop Sand plate 9, whose outer end, 10 'is provided with a bearing and projects beyond the platform 2 and beyond the peripheral edge of and within the receptacle.

Mounted for vertical and oscillatory 30 movement within the terminal 10 of the plate 9 is a shaft 11, which passes upwardly and through the beam v5 and within the super-structure 6, as clearly shown in Fig. 1, are the rods 12 and 13 and the plates and 35 braces 14 and 15, constituting a frame for properly supporting the shaft 11 and its locking device as will presently appear.

The shaft 11 passes through the outer end .of the arm or plate 15, as clearly shown, and in order to limit the upward movement of said shaft is a sleeve 16 mounted below the plate 15. Connected to theupper end of the shaft 11 at 17 and passing through the pulley sheaves 18 and the super-structure 6, is a flexible cable. 17, whose other end is connected with a cylindricalweight 19 disposed to travel as shown .in full and dotted lines in Fig. 1, which weight is sufficiently heavy to. normally retain the parts in the position shown in full lines .in Fig. 1.

Mounted upon the lower end of the "sluift 11 and normally within the receptacle 1 is the cutting and scraping tool 20, which as clearly shown in detail in Fig. 3, is removably attached to the lower'end of the shaft 11 and is provided with the removable cutting or scraping blade or point- 21, the plate 20 being of a flexible metal so as to normally exert aspring tension upon the cutting point- 21 when ,in engagement with the side-of the receptacle 4;.as shown in dotted lines "Fig. 2.- The plate 20. is provided with curved upper corner 21' so as to deflect the freed or cut sugarfrom the body of the scraper or cutter as the receptacle 4 is rotated during thescraping and cutting action. w -Connected dependingly from the under side of the plate 15 are the two posts or pins .22 and '23, respectively, which provide ameans for supporting the catch 24, so that 7 its engaging end 25 will be normally in the path of the handle 27 connected to the shaft 11, when such handle is turned to inoperative position to cause the cutter or scrapingblade to assume the position as shown in full.

lines in.Fig. 2, the spring 26 mounted upon the lower enact the pin 23 and normally holding the free'end of said-shaft in upward 27 when assuming the position as shown in full lines in Fig. 2, locking the said scraper inthe position as shown in full lin'es so that itwill not contact or engage the Walls of the receptacle during the ordinary centrifugal action thereof. By this means the spring 28 remains at thesame relative position while the movement of the shaft 11 will not changeits position as the terminal 28' will slide within thegroove 11- in the. shaft 11] and therefore permit the vertical adjustment of said shaft, the spring at all times exerting the proper and desired tension. To

assist the spring 28, which might not be sufficiently strong to hold the cutter in proper contact with the walls of the centrifugal, the operator may grasp-the handle 27'and push or pull it to' assist said spring and thus eirert a greater pressure of the cutter upon the walls.

-. connection with the drawings, it is evident that when the device is not in use that it will assume the position as shown in Figs. 1 and 2 in full lines. To operate the device it is simply necessaryto release the handle 27 from the catch 24 so that the spring 28 will oscillate the shaft 11 to bring the-cutting point 21 into engagement with the inner wall of the receptacle 4, the parts heing-then in the position shown in dotted lines in Fig. 1. As the receptacle at is being rotated, and the point 21 is placed in engagement with the wall and held thereto by means of the spring 28, sufficient friction is exerted upon the cutting point 21 of the.

movement upon the shaft d1,assisted manually'when necessary by-the operator, to raise the same and that by the time the scraper has moved from the dotted position' as shown-in Fig. 1 to that in full lines therein, the entire 'wall of the receptacle will have been scraped, the manual assistance given the rise of the scraper during its operation preventingany spiral cutting of the sugar from the centrifugal, thereby. insuring the cleaning of the walls entirely of theincrustations.

It will be seen that by this construction that the wall of the centrifugal receptaclemay be cleaned without the necessity of -stopping the machine and scraping with knives as is the usual custom.
