ALEXANDER GIRTANNER, OF ST. LOUIS, MISSOURI, ASSIGNOR OF ONE-HALF TO JAMES A. DAVIESS, OF ST. LOUIS, MISSOURI.

ASH-GON'VEYER.

Specification of Letters Patent.

Patented May 12, 1914.

To all whom it may concern Be it known that I, ALEXANDER GIRTAN- mm, a citizen of the United States of America, residing at the city of St. Louis, State of Missourhhme invented a certain new and useful Ash-Conveyer, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an ash conveyer and consists of various novel features and details of construction, all of which are described in the following specification and pointed out in the claims afiixed thereto.

In the accompanying drawings, which illustrate a conveyor made in accordance with my invention, Figure 1 is a side elevation on a reduced scale showing the complete conveyor; Fig. 2 is an enlarged section on the line 22 of Fig. 3; and Fig. 3 is a sectional view showing the point of junction between the inlet and discharge pipes.

Like marks of reference refer to similar parts in the several views of the drawings.

15 represents a furnace from which the ashes are to be conveyed. Adjacent to each of the furnace doors is a hopper 16.

The various hoppers 16 are included in an inlet pipe 20 forming a portion of the conveyer tube. This inlet pipe 20 joins the discharge pipe 21 at an obtuse angle, as is best shown in Fig. 3 of the drawings. These pipes are brought to ether at an angle for the purpose of provi ing an off-set through which a blower nozzle may be introduced into the pipe substantially in line with the discharge pipe 21. In Figs. 2 and 3 of the drawings, the off-set 22 is provided with an opening 23 which is closed by a plate 24 held in position by bolts 25. Passing through an opening 26 in this plate 24 is a steam supply ipe 27 upon the end of which is screwed a Blast nozzle 28. This blast nozzle bears against the plate 24 and is held in position b means of a nut 29 placed around the tube 2; at the: other side of the late. The blast nozzle 28 is slightly tapere and is provided on its interior with spirally arranged ribs 30 in order to give a twisting motion to the jet of steam as it escapes from the nozzle.

Beyond the point of junction of the pi es 20 and 21, I provide an expansion cham or 40, best shown in Fig. 3. This expansion chamber 40 is entirely unobstructed'so as to allow the steam and ashes to become hoppers 16. Steam is now admitted to the nozzle 28 where it passes into the pipe 21. This steam carries along with it the air in the pipe 20 and thus causes a partial vacuum through which medium the ashes are drawn along the pipe 21 to a position in front of the nozzle where they are carried out by force of the steam. The use of the unobstructed expansion chamber 40, together with the spinal'ribs on the blast nozzle and on the expansion chamber causes the ashes and steam to be thoroughly mixed and thus prevents cloggin "of the pipe.

Having fully escribed my invention, what I claim as new and desire to secure by United States Letters-Patent is:

1. In an ash conveyer, the combination with an inlet 'pipe, of a discharge pipe join-' ing said inlet pipe, and a blast nozzle substantially in line with said discharge pipe, said discharge pipe being provided with an unobstructed expansion chamber adjacent to said blast nozzle.

In an ash conveyer, the combination with an inlet pipe, of a discharge pipe joining said inlet pipe, and a blast nozzle substantially in line with said discharge ipe, said discharge pipe being provided wit an unobstructed expansion chamber adjacent to said blast nozzle said expansion chamber being provided with spiral ribs.
