IMPROVEMENT IN FEATHER-RENOVATORS.

Specification forming part of Letters Patent No. 187,630,

dated February 20, 1877; application filed October 12, 1876.

To all whom it may concern:

- this specification.

The nature of our invention consists in the construction and arrangement of a feather-4 renovator, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which our invention appertains to make and use the same, we will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure l is a longitudinal vertical section oi' our feather-renovator. Fig. 2 is a transverse vertical section of the same.

The frame-work of our machine consists of two end pieces, A A, connected at the top, front, and rear edges by means of cross-bars A1 A1. From these cross-bars depend front and rear hinged doors A2 A2, and thetop of the frame is closed by a hinged lid, A3.

The pau in which the feathers are` placed is composed of a double semi-cylindrical shell, B, forming an interior steam-space, d, and attached to end pieces B B', which are connected, by strips O U, with hollow bearings D D, supported in corresponding openings made for that purpose in the end pieces A'A ofthe frame. This construction isolates the steampipe from the woodwork, and thus prevents the possibility of tire by overheating of the pipe.

In the center of the double or hollow pan B is made a longitudinal recess, a, which is covered by a grating, b, as shown. Below this grating, in the recess d, is placed a perforated plpe, G, extending the entire length of the pan and closed at one end. `At the other end is an angular pipe, G2, passing out through one of the hollow bearings, and the outer end of this pipeis to be connected with the Steamboiler by a suitable iiexible pipe. Through the same hollow bearing passes another pipe, G1, also to `be connected, by a iiexible pipe, with the boiler; and this pipe G1 enters the steam-space d of the pan, as seen in Fig. 2. In the pipes G1 and G2, outside of the bearing D, are to besuitable vstop-cocks, for shutting oi' and admitting steam, as required, either to the one or the other pipe. The pan. B, being hung upon the bearings D D,can beswung backward and forward with perfect ease. The feathers arefirst placed in the pan B, a-nd the steam admitted through the pipe G2 into the pipe G, from whenceit, passingout and through the grating b, will permeate the entire mass of feathers, so as to loosen the dirt therein, which dirt, with the condensed steam, passes down through the grating into the recess or chamber a. The steam is then shut off from the pipe GJ and admitted into the pipe G1, to enter the chamberd to heat and dry the feathers.

When thoroughly dry the feathers are emptied by opening the doors A2 and tilting the pan either backward or forward, as desired. The feathers are admitted from the top by opening the lid A3. f

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

ln a feather-renovator, the combination of a stationary frame, provided with hinged side doors A2 AZ and hinged lid A3, the semicircular hollow pan B, suspended from the bearings Dby one or more straps, C, at each end,and the pipes G1 G2, passing through the bearing at one end, and their lower ends entering into the chamber in the pan and into the perforated tube G, respectively, all substantially as and for the purposes herein Set forth.

In testimony that we claim the foregoing we r have hereunto set our hands this 16th day of September, i876.
