Patented Sept. 26, 1939 UNITED STATES MEANS AND METHOD OF REMOVING BARBS AND DOWN FROM THESTEMS OF FEATHERS Warren H. Edmister, San Diego, Calif. Application April 6, 1938, Serial No. 200,503

10 Claims.

My invention relates to a means and method of removing barbs and down from the stem of feathers and the objects of my invention are:

First, to provide a means of cutting and tearing all of the barbs and down from the stems of feathers;

Second, to provide such a means that at the same time as it is out and torn will separate the down and barbs from the stem;

Third, to provide a means of this class in which the barbs and down are placed in one receptacle and the stems are left in another receptacle;

Fourth, to provide a means of this class in which all of the barbs and down are taken from the stems of the feathers and segregated by the same means;

Fifth, to provide a novel method of removing barbs and down from the stem of feathers;

Sixth, to provide a novel method of separating the barbs and down from the stems; and

Seventh, to provide a means and method of this class which is very simple and economical of operation and efiicient in its action.

Eighth, to provide a means of this class which is very simple and economical of construction, efficient in its action and which will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter, my invention consists of the certain novel construction, combination, and arrangement of parts and portions and the novel method as will be hereinafter described in detail and particularly set forth in the appended claims, reference being bad to the accompanying drawing and to the characters of reference thereon which form a part of this application in which:

Figure 1 is a longitudinal sectional view of my means of removing barbs and down from the stems of feathers showing some of the parts in elevation to facilitate the illustration; Fig. 2 is a transverse sectional view taken from the line 2-2 of Fig. 1; Fig. 3 is another transverse sectional view taken from the line 33 of Fig. 1; and Fig. 4 is an enlarged sectional view of a fragmentary portion of the lower side of the feather receptacle as shown in Fig. 1 of the drawing and showing certain portions in elevation to facilitate the illustration.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawing:

The sand conducting tube I, air conducting tube 2, feather receptacle 3, screen 4, and bag 5 con stitute the principal parts and portions of my means of removing barbs and down from the stems of feathers and also shows the apparatus used in my method of removing barbs and down from the feathers.

The sand tube I and air tube 2 form the parts of a conventional air sand blast, the sand tube I extending to a hopper or other supply of sand while the tube 2 extends to and connects with air under pressure, either a pressure tank or a pump, as desired.

The extended end of the tube 2 extends into a receptacle 3 substantially at the center of the receptacle at one end at 2a and this portion 2a is slightly belled at the end so as to provide a scattering of the air and sand as it leaves the end 2a. It will be noted that this end extends a slight distance into the receptacle 3 at the center thereof as shown in Fig. l of the drawing. This receptacle 3 is preferably made of metal and is cylindrical in form andclosed at one end at 3ainto which the member 2 extends and is secured thereto. The other end of the receptacle is open and is provided with an enlarged turned portion 3b at the edge. It will be noted that thisreceptacle 3 gradually enlarges and is preferably positioned on an angle to the horizontal as shown in Fig. 1 of the drawing. This receptacle is provided near its lower side with a door member 30 by means of hinge member 301. with a ring member 3e to facilitate the opening and closing of said door. This is for the purpose of admitting feathers to the receptacle and also for removing the stems of the feathers after the barbs and down have been removed therefrom.

Mounted over the open end of the receptacle 3 and extending over the enlarged portion 3b is a screen 4 which is of the proper mesh to the feather stems from passing through but permit the barbs and down and sand to pass therethrough, the sand in its blast carrying the down and barbs through the screen. This screen is secured on the receptacle 3 by means of a band 3 which extends around the receptacle adjacent the enlarged portion 312. This band, however, is positioned on the outside of the open end of a bag 5 which is made of fabric, such as the like, which permits the air to' pass through, but will hold the sand and barbs and down. This bag 5 may be of any suitable size for holding a large amount of the down and barbs and sand and with the open end adapted to fit snugly around the larger open end of the receptacle 3 and secured by the band 3 in position.

The operation of my means and method is as follows:

The feathers to be treated are placed in the reexclude gunny sack or ceptacle 3 through the door 30 or otherwise, then a sand blast is turned onto the feathers which spreads and passes through the feathers tearing and cutting the barbs and down from the stem and carrying them through the screen 4 into the bag 5 and leaving the stems in the receptacle 3. Then the bag is removed and the barbs, down and sand are removed therefrom. Then the door 30 is opened and the stems removed from the receptacle 3. Then more feathers are placed in the receptacle 3 and the bag replaced and the steps repeated as before set forth. The sand is easily removed from the barbs and down by the use of a fan of conventional type.

Though I have shown and described a particular construction, combination, and arrangement of parts and portions and described a certain method, I do not wish to be limited to the particular construction, combination and arrange ment, nor to the particular method, but desire to include in the scope of my invention the construction, combination and arrangement and process substantially as set forth in the appended claims.

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

1. In a means for removing barbs and down from the stems of feathers, the combination with a sand blast, of a feather receptacle into which the nozzle of said sand blast extends at one side, a screen over the opposite side and a forarninous receptacle in communication with said screen.

2. In a means for removing barbs and down from the stems of feathers, the combination with a sand blast, of a feather receptacle into which the nozzle of said sand blast extends at one side, a screen over the opposite side, and a perforate bag positioned over said receptacle at the screen end.

3. In a means for removing barbs and down from the stems of feathers, the combination with a sand blast, of a feather receptacle into which the nozzle of said sand blast extends at one side, a screen over the opposite side, a perforate bag positioned over said receptacle at the screen end, and means for readily securing said bag thereon.

4. In a means for removing barbs and down from the stems of feathers, the combination with a sand blast nozzle, of a bucket-like receptacle with a closed end and open end, the closed end connecting with said nozzle at its middle, said nozzle extending some distance into said receptacle, a screen mounted over the open end thereof and another receptacle in communication with said screen.

5. In a means for removing barbs and down from the stems of feathers, the combination with a sand blast nozzle, of a bucket-like receptacle with a closed end and open end, the closed end connecting with said nozzle at its middle, said nozzle extending some distance into said receptacle, a screen mounted over the open end thereof, a door in one side of said receptacle and another receptacle in communication with said screen.

6. In a means of removing barbs and down from the stems of feathers, the combination with a sand blast nozzle, of a bucket-like receptacle with a closed end and open end, the closed and connecting with said nozzle at its middle, said nozzle extending some distance into said receptacle, a screen mounted over the open end thereof, a door in one side of said receptacle, and a foraminous bag mounted over the open end of said receptacle and said screen.

7. In a means of removing barbs and down from the stems of feathers, the combination with a sand blast nozzle, of a bucket-like receptacle with a closed end and open end, the closed end connecting with said nozzle at its middle, said nozzle extending some distance into said receptacle, a screen mounted over the open end thereof, a door in one side of said receptacle, a foraminous bag mounted over the open end of said receptacle and said screen, and means for readily securing said bag over the open end of said receptacle and screen.
