HENRY L. DAY, OF MINNEAPOLIS, MINNESOTA.

FLOOR-SWEEP.

Specification of Letters Patent.

PatentedJune 11, 1912.

I Application filed December 7, 1908. Serial No. 466,297.

To all whom it may concern:

Be it known that I, HENRY L. DAY, of Minneapolis, in the county of I-Iennepin, State of Minnesota, have invented certain new and useful Improvements in Floor- Sweeps, of which the following is a specification.

This invention relates to improvements in devices known as floor-sweeps, which are adapted for use in connection with dust collecting systems for collecting grain, mixed with dust, screenings, and other light material, and delivering the same to the main conductor of a dust collecting system.

The device herein described is particularly adapted for use in connection with a dust collecting system such as shown, described and claimed in my applications for patent of even date herewith, numbered 466,294 and 466,295.

In the accompanying drawings, forming part of this specification; Figure 1 is a sectional elevation of a portion of a grain cleaning house, or similar structure, having my improved floor-sweep arranged therein. Fig. 2 is a similar View showing a modified structure. Fig. 3 is a vertical section, and Fig. 4 an end elevation of one of the separators used in connection therewith.

In all of the drawings, 2 represents a pipe or conductor that is connectedwith the main conductor 3 of a dust collecting system. The

pipe 2 may be an extension or continuation of the main conductor, or it may be a separate branch conductor connected to the main conductor, and I may employ a number of the pipes or conductors 2 and connect all of them to the same main conductor.

Floor-sweeps, such as described herein, may be connected to each'of the conductors 2, or other dust separating devices may be connected with said floor-sweeps to the same conductor or to dilferent conductors.

4.14 represent floors or galleries of a suitable grain cleaning house, or other structure, where the device is to be employed.

I prefer to arrange below each floor a separator 5 shown in detail in Figs. 8 and 4: of the drawings. This separator consists of a chamber having, preferably, side walls and with one vertical end wall and onesloping end wall, whereby a pocket 6 is formed in the lower part of the separator, which has an opening at its lower end that is closed by an automatic door or valve 7.

An inclined deflector 8 is preferably arranged near the central part of the separator and above the pocket 6 and suitable valve openings 9, l0 and 11 are preferably provided in the straight end wall and the top wall of the separator. The opening 9 is preferably arranged below the deflector 8.

An inlet conductor 12 is provided at the upper end of the separator. This conductor preferably extends through the floor 4. and is provided with a suitable mouth-piece or inlet 13 having a valve or door 14. The separator is also provided at the top of the inclined wall 5 with the outlet conductor 15 and this is connected directly or indirectly with the conductor 2, .hereinbefore described.

16 represents a suitable fan casing, from which extends a conductor 17 that leads to a dust collector 18. The dust outlet of this dust collector is provided with a pipe 19, which leads to any suitable'receptacle or discharging point for the dust passing through said pipe 19.

Instead of using a separator 5 below each floor, I may, if preferred, employ a single separator, as shown in Fig. 2 of the drawings, and extend the conductor 12 through each of the floors 1 and provide it with an inlet or mouth-piece 13 at each floor.

With the construction shown in Fig. 1,

mixed grain, dust and like material may be swept from each floor into the inlet 13 provided on said floor. The mixed material falls into the separator'5. With the structure shown in Fig. 1, this will be the separator below each floor.

With the structure shown in Fig. 2, the material from all of the floors will fall into the same separator.

In either event, the mixed material entering the separator will be subjected to the upward and transverse air currents and the dust and light material will betaken out by the air current and carried through the conductor 15 into the conductor 2 and thence to the fan and dust collector 18. The grain and heavy material will fall into the pocket 6 and when a suflicient amount has accumulated therein, its Weight will open the door 7 and its material will fall out through a suitable spout or receptacle.

I claim as my invention:

The combination, with a dust collecting system-arranged in a grain-cleaning house or other structure, having a series of floors,

a separating chamber located below each tem in communication with all of the sepafioor connected with said clust collecting sysrating chambers. 10 tem, and a sweep opening above each floor In witness whereof, I have hereunto set through which grain and other material my hand this 30th day of November 1908.

5 may be swept from the floor into said sepa- HENRY L. DAY.
