SPECIFICATION forming part or Reissued Letters Patent No. 1 1,549, dated June '23, 1896. Original No. 557,05 9, dated March 24, 1896. Application for reissue filed Mayll, 1896. Serial No. 591,184.

To all whom it may concern/.2

Be it known that I, JAMES M. DODGE, a citizen of the United States,.residing in Philadelphia, Pennsylvania, have invented certain Improvements in Conveyers, (suction,) of which the following is a specification.

My invention is based on the patent granted to me on the 20th day of August, 1895, No. 545,013, for improvements in the process of and apparatus for conveying material.

The object of my present invention is to convey bysuction, the/decrease of pressure within the conveyer causing the atmospheric pressure to exert a propelling influence upon the material.

In the accompanying drawings, Figure 1 is a side view of my improved conveyer. Fig. 2.

is a longitudinal sectional View; and Fig. 3 is a transverse sectional viewon the line 3 3, Fig. 2.

Referring to the accompanying drawings, A is a tubular conveyer, being closed at the top and sides and having a series of openings to at the bottom. These openings are in they present instance narrow slots formed at an angle, so that the air entering the conveyer will not only lift the material, but will aid the suction apparatus to convey it along the trough. The bottom or bed of the conveyer may be made in sections, as in my former patents;

B isa hopper or other receptacle, which has a neck b leading to one end of the conveyer.

A, and this Qhopper may be provided with a valve or other suitable device for regulating the fiow of material to the conveyer. At the opposite end of the conveyer is a suction-fan D of the ordinary construction and so connected to the conveyer and of sucha capacity that it will produce a partial vacuum in the con'veyerA, and the air entering the conveyer through the openings at will have sufiicient force to carry the material along the tube in the direction of the arrow.

ai sthe outlet-passage leading to a suitable receptacle or to another conveying appa ratus, and eis a curved deflector, the portion 6 being solid, while the portion 2 is perforated to allow airto freely enter the suction apparatus. Some of the material will strike the solid portion e of the deflector and willbe acting to reduce the pressure in the conVeyertube below atmospheric pressure, substanv tially as described.

2. The combination ina tubular conveyer having a series of openings. therein and having an inlet and an outlet for the material, suction apparatus communicating with the out let end of the conveyer, the said openings inthe conveyer being inclined toward the outlet end, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
