JACOB LINGENFELTER, OF BLOODY RUN, PENNSYLVANIA.

Leners Patent Nb. 11am-adam April 11, 1an.

lNlPllQllEllvlEhlTl IN MILLSTNE EXHAUSTS.

The Schedule referred to in these Letters Patent and making part of the lame.

To all 'whom-it may concer-n: l

Be it known that I, JACOB LINGENFELTER, ef Bloody Run, in the county of Bedford and State of Pennsylvania, have invented a new and valuable Improvement in Millstone Exhaust; and I do` hereby declare that the following is a full, clear, and exact description'of the coi'istruction and operation of thev same, reference being had to the annexed drawing making a part of this specification and tothe letters and figures ef reference marked thereon.

Figure 1 of the drawing is a side view of my improved exhaust-pipe.

Figure 2 is a front View of the same.

My invention is an improvement upon the apparatus for which Letters -Patent of the United States Wee granted to David Baird, December, 1867; an

It consists in the means provided for saving any dust or fine lour which may be drawn up by the eX- hanet, and for carrying oli` the condensed steam and moisture. l

The letter A of the drawing represents the runner.

' C, the exhaust-pipe, provided with the expanded chamber D at its lower end.

E designates the upper expansion leading to the fan; and

F the waste-pipe or conduit which conveys away the condensed steam and moisture.

G represents an elbow or inclined section of the exhaust-pipe, designed to cause the water of condensation to flow back into the funnel a of the wastepipe F.

The object of `expanding the lower end of the exhanstfpipe is to effect a slow draught in this portion,-

thereby giving the line particles of floundust which are drawn upward with the steam sniicient time to enable them to become dampened by itscondensation, thus acquiring snicient weight to cause them to fall.

Thus a great saving is accomplished, and this expansin or chamber D is so well adapted to the object in view that flour-dust is never carried beyond the rst bend in the pipe, andv therefore both the elbow Gr and the pipes and chambers above it are never coated, but always bright and clean. l

rlhe chambers andpipe abovethe elbow G being suitably arranged, all the water of condensation is conveyed back into this portion of theV pipe and runs alen g its inclined bottom into the funnehshaped mouth of the conduit F, whereby it is carried wherever it may be desired. v

By these simple devices the millst-one exhaust is rendered efficient and `economical. Time and labor are saved, as well,` as a great quantity of the finest quality of flour.

What I claim as my iuvention,.and desire to secure by Letters Patent, is-

' l. At the lowei' end of a'umillstone exhaust-pipe,4

the enlarged chamber D, when constructed and arranged to operate in the manner and for the purpose shown and described.

2. In combination with the expanded chamber D, at the lower end of a millstone exhaust-pipe, the inclined elbow G and waste-pipe F, as specified.

In testimony' that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
