ODORLESS EXCAVATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 231,827, dated August 31, 1880. Application filed June 21, 1879.

.To all whom it may concern:

Be it known that I, ALFRED W. J. MASON, a resident of the city of New Orleans, parish of Orleans, and State of Louisiana, have in vented a certain new and useful Improvement in Odorless Apparatus for .Oleaning Privy- Vaults; and I do hereby declare the following to be a full, clear, and correct description of the same, reference being had to the annexed drawing, making a part of this specification.

This invention relates to odorless apparatus or means for cleaning privy-vaults; and the novelty consists of an air-tight elevator, in combination with a receiving-tank and deodorizer.

The object of this improvement is to do away with the expensive air-pumps now employed in this system, and substitute in lieu thereof a portable air-tight elevator which shall be simple and cheap in construction.

On the drawing, A is intended to represent a privy-vault, B an air-tight elevator, C a receiving-tank, and D a deodorizing-vessel.

The elevator B, like others of its class, has its casing composed of two tubes, to b, the ends of which are connected, as at c 01. I11 these ends are fitted, upon shafts c f, suitable drums, over which operates an endless band, G, the latter provided with a number of elevatingbuckets, as at h.

The lower end of the casing isleft open and provided with a screen, I, and over the same is secured, after each operation, an air-ti ht cap, L, so as to effectually exclude all smell at the said point during the removal or transportation of the same. The dischageopening at the upper end of the casing should also be provided with a detachable cap for a like purpose.

The tank 0 is furnished at one side wit-h a gage, i, to exhibit the quantity of matter therein, and the deodorizer is provided with a removable cover, 70, to admit of a furnace being placed thereupon. The tank 0 is connected for operation with the upper end of the elevator and deodorizer by means of pipes l and on.

To operate the invention, first removethe air-tight cap L from the lower end of the elevator, then sink the said end \Vllll its screen into the privy-vault, nextremove the cap from the upper end of the casing, and make the pipe-connections between the elevator, tank, and (leodorizer. Remove the cover from the latter vessel, and place in lieu of same a furnace with lighted charcoal or other fuel therein. The machine is" then put-into operation by turning the cranks of the elevator in the direction indicated by the arrows.

The gage on the receiving-tank will show when to stop the apparatus, and the fire in the furnace wtll destroy all gases passing into the deodorizer.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The elevator B, composed of tubes (1. b, united at their ends, but having the lower end reticulated, and the endless band G, provided with a series of buckets passing over drums arranged on the shafts cf, substantially as set forth.-

2., In an apparatus of the odorless class, the elevator B, provided with an endless band, Gr, carrying a series of buckets, and having the lower end which enters the vault reticulated and provided with the air-tight cap L, covering the said reticulated portion of the elevator, substantially as described.

3. An odorless excavating apparatus consisting of the elevator B, carrying a plurality of elevating-buckets, and having its lower end reticulated, a connectingpipe, Z, receivingtank 0, with transparent gage, connectingpipe m, and a deodorizer, D, substantially as shown and set forth.

In testimony whereof I have hereunto signed my name.

ALFRED WV. J. MASON.

In presence of FRANK REGEL, HUGH PIERSON.
