\VILLIAIWI J. PURDY, OF OARBERRY, MANITOBA, CANADA, ASSIGNOR OF TVVO- TI-IIRDS TO JOHN PETERS ANDERSON AND ROBERT HENRY D. S. MON- TAGU, BOTH OF SALE PLACE.

BUCKET-ELEVATOR FOR FL OURING-MILLS.

SPECIFICATION forming part of Letters Patent No. 415,819, dated November 26, 1889.

Application filed July 31, 1889. $en'a1 No. 319,351. (No models) To all whom it may concern.-

Be it known that I, WILLIAM J ETHRO PURDY, of Oarberry, in the county of Norfolk, in the Province of Manitoba, in the Dominion of Canada, have invented a certain new and useful Improvement in Bucket-Elevators for Flouring-Mills; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to To the accompanying drawings.

Figure 1 is a section of a portion of a bucketelevator, showing my cleaner or brush applied thereto. proved elevator on the line as as, Fig. 1. Figs.

3, 4c, and 5 are perspective views of detached portions of the brush to show the construction.

My invention has for its objects to remove the accumulation of flour adhering to the trunk or tube of flour-elevators, and thereby prevent flour from being deteriorated by the accumulation loosening after becoming musty and mixing with the Hour, and also, by removal of such accumulation, to prevent the tube or trunk from becoming rotten, because of the dampness in the adhesive particles of flour.

My invention consists in securing to the elevator-belt, and between the cups or buckets thereon, one or more brushes which will sweep three sides of the trunk and thereby prevent accumulation of flour adhering to the interior.

A is the endless belt, B the cups or buckets, and C the tube or trunk of the elevator as used in flouring-mills.

D is a brush riveted to the belt, and has frictional contact with three sides of the elevator-tube O to sweep off particles of flour, which, owing to the heat and moisture generated in manufacturing or grinding, cling to the sides of the elevator-trunk, and if not removed become musty, rot the trunk, and injure the fiour.

Fig. 2 is a section of my i1n- The brush D is preferably composed of a metallic rectangular frame E, having a central opening J, and provided with a flange 2, which is secured to the belt by rivets or bolts F to hold the brush at right angles to the belt, and to said frame E is secured a U- shaped cover-plate G, corresponding to three sides of frame E and placed one over the other.

H H are flexible plates of rubber, cloth, leather,orother suitable material intervening the frame E and cover G and project from the outside edge on three sides, and between said plates III-I and projecting therefrom is secured a brushing I, of bristles, steel Wire, or other suitable material, by bolts or rivets 6o 3, which pass through and compress together the frame E and cover G to hold the plates H H and brushing I interveningly. The brushing I sweeps the finer particles of flour which have adhered to the tube during the operation of the elevator, and the dislodged material passes through the aperture J in the brush and falls into the bucket or cup below.

I claim as my invention 1. The combination, with the elevator-tube O and endless belt A, having cups orbuckets B, of an open-framed brush D, having one side attached 'to the belt and its bristle or wire ends arranged in frictional contact with three sides of the tube, as set forth.

2. The combination, with the elevator trunk or tube 0 and endless belt A, having buckets or cups B, of a brush D, provided with a central aperture J and secured to the So belt to sweep three sides of the trunk or tube, as set forth.

\VILLIAM J. PURDY.
