JACOB BERN'STEIN, OF OMAHA, NEBRASKA.

SOOT COLLECTOR.

' Application filed May 20,

T 0 all whom it may concern:

Be it known that I, JACOB Bnnnsrnm, a citizen of the United States, and a resident of Omaha, in the county of Douglas and State of Nebraska, have invented a new and useful Improvement in Soot Collectors, of which the following is a full, clear, and exact description.

My invention relates to soot collecting devices, and it consists in the combinations, constructions and arrangements herein described and claimed.

An object of my invention is to provide a soot collector that is adapted for use in drawing soot from the smoke outlet of a heating apparatus and for conducting the soot to a desired place, as for instance, to a bag or other receptacle.

A further object of my invention is to provide a device of the character described that is capable of being moved. readily from place to place for use in turn at widely separated points.

A further object of my invention is to provide a device of the character described that is relatively simple in construction and operation and not likely to get out of order easily.

A further object of my invention is to provide a soot collector that is thoroughly effective for the purpose intended and can be operated at a relatively low cost.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointedout in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which- Figure 1 is a side elevation of the device, portions thereof being broken away and other portions being shown in section.

Figure 2 is an enlarged plan view of the device, portions thereof being broken away and other portions being shown in section,

Figure 3 is a sectional detail of a frugmentary portion of the device, and

Figure 4 is a detail of another fragmentary portion of the device.

In carrying out my invention, I make use of a vehicle which may be of any suitable type of construction and, in the drawings, is indicated generally at 1. Mounted upon the vehicle 1 is a power device 2 of ordinary construction. I prefer to use an internal combustion engine of an ordinary and well known type as the power mechanism in the Specification of Letters Patent.

device. The internal combustion engine is secured by bolts 3 or other fastening means to the body of the vehicle. A fan f: of the blower type is supported by a base that is likewise secured to the vehicle body by suitable fastening means, such as the bolts (3. The fan at is driven by a belt an d pulley connection indicated generally at T with the internal combustion engine 2. An intake or suction conduit 8 communicatively connects at one end with the fan 4 adjacent to the axis of the latt r and is adapted for connection at its other end with a flexible tube 9, A delivery tube 10 leads from the periphery of the fan 4 and branches at 11 to provide two

branch delivery tubes

12 and 13 respectively. The branch delivery tube 12 opens into a soot receiving member 14 through the side wall of the latter adjacent to its upper end, as best seen in Figure 3. The branch tube 13 likewise communicates with a similar soot receiving member 15 through the side wall of the latter adjacent to its upper end.

The

soot receiving members

14 and 15 are substantially identical with one another in essential respects and each has the form of an inverted cone closed at its upper end except for a central opening 16 having a tubular extension 17 depending therefrom. Each soot collecting cone is provided with a discharge orifice 18 at its lower end and a suitable receptacle 19 which may be a bag, is removably secured at 20 at the lower end of each cone to receive the soot passing through the discharge orifice 18. Ar-

ranged to enter the opening 16 to depend.

within each cone is the tubular portion 21 of a header 22 which is enlarged exteriorly of the cone so that the walls thereof are inclined outwardly, as shown. The header 22 is provided with an upper end wall which has a central opening 2%. An upstanding tubular member from the opening 24: is integral with the wall 23. An intake tube 26 is arranged to enter the tubu lar member 25 to depend through the opening 24 into the header 22 to a point slightly below the level of the upper end of the cone. A screen supporting frame 27 has a tubular stem 28 disposed in the upper end of the intake tube 26 and supported by the latter. The screen supporting frame 27 is covered by a screen 28 of suitable mesh and is provided with radially extending brace rods 29. Certain of the brace rods 29 connect with the tubular stem 28, while 'others are stayed by a tie member 30. The stem 28 is fashioned with an inwardly extending lug 31 constituting a bearing for a crank 32. A brush 33 is carried by the crank arm 32 in position to engage the inner wall of the screen 28 when the crank is rotated. The screen 28 may consist of a suitable fabric, preferably a heavy cloth, and be renewed when worn or damaged in service. A return conduit 3 is provided for each head 22 and connects with the latter adjacent to its upper end. The conduits 3% unite at 35 to provide a main return conduit 36 that communicates with the fan i adjacent to the axis of the latter.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. The flexible tube 9 may be formed of sections to provide any suitable length and the end thereof is connected to the smoke outlet of the heating apparatus from which the soot is to be drawn. The fan at is then operated and soot is drawn through the intake conduit 8 and blown therefrom through the delivery tube 10 and, through the

branch delivery tubes

12 and 13 into the

soot receiving cones

14 and 15. It is to be observed that the air with the entrained soot forced along the delivery tube 10 enters each Cone through its side wall at the upper end of the latter and the mingled soot and air will pass in spiral convolutions of decreasing diameter downwardly through the soot receiving cone, thereby creating a partial vacuum at the center of each cone. The soot will be discharged through the discharge orifice S into the receptacles 19. The return tube 36also communicates with the fan 4 adjacent to the axis of the latterrand the operation of the fan will cause a suction on the head 22 which will tend to draw air upwardly from the center of the cone, thereby drawing practically all air from the cone into the branch return tubes 3d, while practically all of the soot passes into the receptacles 1.). In the event any of the finer soot passes up ardly with the air drawn into the tubes it may pass along the latter to the fan f and he forced through the delivery tube 10 again. Any soot entering the tubular intake member 26 will be caught by the screen 23 and may be dislodged therefrom by operating the crank 32 either before or after the screen frame has been removed from the header 22. It will thus be obvious that practically all the soot drawn from the flue is collected. The device may be moved readily from place to place and is ready for operation instantly. The soot receiving cones la and 15 are supported on the vehicle body by suitable fastening means, such as the brackets 37.

I claim: 1. In a device of the character described,
