4 Claims.

v renovated and finally delivered to the pillow ticking in a sanitary and iluied condition.

An important object of the invention resides in the provision of means whereby a batch of soiled feathers is induced into a chamber and subjected to an agitating or beating operation to remove dust and dirt, and subsequently treated with live steam, and a deodorant, if desired, and then treated with hot air to dry the batch, and` finally introducing cool air whereby said batch of feathers is reduced to a clean, cool, sanitary and iiuffed condition.

Another object is to provide suction means whereby the feathers are drawn into the cleaning chamber forr treatment as aforesaid, such suction means also serving yto remove foreign matter deposited in said chamber, to induce a iiow of hot air through. the feathers, and thenw a flow of cold air through the same, and finally to deliver said feathers to the ticking normally containing the batch of feathers.

A further object of the invention is to provide means to prevent the clogging of the discharge end of the cleaning chamber with feathers, said means being operable in conjunction with certain beaters lwithin said chamber I and being controlled to become operative only at the screen positioned in said 'discharge end.

rA still further object is the production of a mechanism whereby the feathers entrained with the air currents discharged into the normal ticking of the pillow are restrained from clogging or closing the air ports normally provided for the escape of the air.

Other objects and advantages ofthe inventionv will be apparent as the nature thereof is better set forth, and it will be understood that changes within the scope of the claims may be resorted to without departing from the spirit oi the invention.

Fig. 8 is a. plan view of an annulus associated with said means.

Referring now more in detail to the accompanying drawings wherein like characters of reference denote similar parts throughout the 10 several views, 5 indicates the treating chamber which is defined by a drum 6, the sides thereof carrying a rotatable shaft 'I mounting a plurality of beatersv 8, said shaft being provided with a pulley. 9 adapted to be belted to any suitable 15 source of power.k One end of said drum 6 is provided with an inlet opening I Il to which is connected the branch II leading from the chute I2 the upper portion of said chute being provided with a hopper I3 having a hinged door 20 I4. The other end of saidr drum 6 is provided with a discharge opening I5, closed by a screen I6, piping I1 connecting said opening to the intake end of a fan I8, the discharge end of the latter being coupled to a conduit I9 having 25 its upper end normally open to the atmosphere. As shown in Figs. 1 and 2, said drum 6 may be supported by a cradle to assure a sturdy arrangement, while ther upper portion of said' drum is provided with brackets 2l mounting'a 30 chest 22, containing coiled piping 23 adapted to receive a heating medium, such as steam, from the piping 24, one end of said chest lbeing closed by a hinged shutter 25, Whilst the other end is provided with a screened opening 2B.

Without implying any 'limitation in the use of the machine it is preferred to treat at one time the normal contents of the ticking of a pillow in order that it may be assured that the original contents, in a cleaned condition, 40 will be returned to the ticking after the several operations have been performed. Thus, the ticking may be emptied of its contents into the hopper I3 after the door I4 has been elevated, such contents then gravitating to the bottom of the `chute i2 to a the screened opening 21 through which any foreign matter such as sand or similar heavy particles descend into the receptacle 28 for subsequent removal. i

The feathers are now in a position and condition to -be delivered into the treating chamber 5 of the drum 6 by way of the inlet opening I0, the means employed for transporting the feathers to said chamber being the air currents induced by said suction fan I8. As shown in Fig. l, said branch II and said piping I1 are provided with valves 29 and 30, respectively, and when both valves are opened and the fan started, the air currents draw the batch of feathers into said chamber by way of opening I0, said screen I6 in opening I5 preventing the passage of any feathers to the piping I1 but allowing free passage of the air currents as will be well understood. The rotatable beaters 8 mounted on shaft 1 which are driven as aforesaid, agitate and literally beat the feathers to remove and extract the residual dust and dirt therefrom,

whereupon said fan I8 is stopped and the valves 29 and 30 are closed. In order to thoroughly clean and sterilize the feathers, I propose to admit steam into said chamber 5 by way of pipe 3|, the temperature in said chamber being observed by the thermometer 32, and the built-up pressure therein being registered by the gauge 33 and controlled by the relief-valve 34. It will be understood that during the admission and retention of the steam within said chamber, said beaters 8 are in operation thus agitating the feathers and Yassuring that the steam will penetrate and operate on each individual feather.

After these cleaning and sterilizing operations certain chemicals or deodorants may be introduced into the chamber 5 from a suitable container 35. l

In order to thoroughly dry and fluff the feathers a stream of hot air is next passed through the chamber 5, said hot air being drawn from the steam chest 22 by means of fan I8, the shutter 25 being swung to the position indicated by dotted lines in Fig. l, thus closing the hopper I3 whilst valves 29 and 30 are opened. The air is, of course, 'drawn originally through the screened opening 26 into the chest 22 where it is heated bythe steam coils 23 and from said chest it passes through chute I2 and into the chamber by way of opening I8.

Finally the hinged shutter 25 is swung back to its original position thereby closing said steam chest and shutting off the passage of hot air to said chamber 5. In order to permit the passage of cold air to the chamber 5 the hopper closure I4 is opened so that cool air currents are induced by fan I8 into said chamber 5 by way of chute I2 and opening I6, said cool air currents operating to thoroughly cool the'feathers within said chamber before their delivery tothe original container. The batch of feathers being ready for delivery to the ticking A, screen I6, mounted un slide Isa, (see Figs. 1 and 3), is withdrawn,

and the operating'fan I8 now draws the batch from the chamber 5 and delivers it to the ticking A by way of conduit I9 and piping 36, valves 31 and 38 being interposed in the conduit I9 and piping 36, respectively, which are operated to open and close these elements during the aforesaid manipulations.

It is obvious that when the feathers are initially drawn into the drum 5 by. the air currents induced by the fan I8, said feathers will try to escape through said screen I6 in the outlet I5, thus clogging said screen and shutting off the passage of the induced air currents. In order to remove such accumulations of feathers on said screen I propose toprovide means in the nature of a wiper which comprises an arm 39 having its hub 40 splined to said shaft 1 and being rotatable therewith so that the wiper element 4I will intermittently engage `the surface of said screen I6 and remove the clinging feathers. Manifestly the wiper 4I only engages the screen during a small portion of its rotation and in order to reduce unnecessary wear it is important that the wiper be temporarily removed from its normal contact with the interior surface of the end wall of the drum. To this end said hub 40 is slidably mounted on the key 42, (see Figs. 1 and 4), and normally assumes the position shown in said Fig. 1. However, when the wiper 4I leaves the screen I6 its arm 33 encounters the circular track or rib 43 which slides the hub 40 along said shaft 1 and the wiper is spaced from the side wall of the drum. As the rotating wiper approaches the screen I6 it leaves the track and the spring 44 returns the wiper to its operative position. This is a feature of some importance.

When the feathers are discharged into the ticking A they travel along with the air currents and in order that the operation may be successful it is vital that the air currents escape from the ticking. As the interstices in the fabric comprising the Vticking are notsumcient to release said air currents, it has been proposed to provide openings for the release of the air, and in order to prevent the escape of the feathers, certain screening has been interposed. Here again the efficiency of such anl arrangement is seriously impaired in that the feathers will attach themselves to the screen, clog the same and prevent the escape of the air currents. As will presently appear, I provide screened openings to release the air and also means to prevent clogging of said openings.

The aforesaid means comprises an annulus 45 having a plurality of radially directed arms 46, (see Fig. 8), whose inner ends engage the end of the piping 38, (see Figs. 5 and 6), said annulus being provided with a circumferential flange 41v over which the open end portion of the ticking A may be slipped and tied by the element B. It will be seen that said arms 46, the adjacent internal Walls of the annulus and the sides of the piping 36 unite to denne openings for the escape of the air currents that carry the vfeathers into the ticking. In order to close said openings against the escape of said feathers, I interpose a screening 48 having an open frame 46 to permit the entrance of the piping 36, and also including an outer frame 50 mounting a handle arrangement 5I. f Said screen normally rests on the upper edge of said annulus 45 as shown in Fig. 5, whereupon the ring 52 threadedly engages said annulus 45 to mount the parts inthe positions indicated, the arrangement being such that said screening 48 may be oscillated or completely rotated when assembled as aforesaid. When the feathers enter the ticking A, the air currents will escape through the screened openings between the radial -arms 46 and in order to dislodge any feathers clogging said screen it is only necessary to grasp handle 5I and rotate said screen on the piping 36. lIn view of the provision of brushes 53, suitably carried by said arms 46, the accumulations of feathers will be readily scraped from the screen during its operation as aforesaid. Thus, an arrangement is provided to permit the escape of the transporting air currents and means is adopted to remove the cause of a serious `impairment to this essential arleading to said inlet, a heating chest having one end open to the atmosphere, a shutter interposed between said chest and said chute and adapted to be operated to close said chute at its upper end and place said chest in communication with said treating chamber, and an exhaust fan having its intake end connected to the outlet of said chamber and adapted to draw heated air from said heating chest through said chamber and to draw cool air through said chamber when said shutter is closed.

2. A machine of the class described comprising a treating chamber having an inlet and an outlet for feathers, an exhaust fan connected to said outlet to draw feathers into said chamber, a screen mounted in said outlet, rotatable beaters mounted in said chamber, a shaft supporting said beaters, a rotatable member carried by said shaft and adapted to contact said screen to remove the accumulations of feathers thereon and means carried by one of the side `walls of said chamber and adapted to engage said rotatable member and slide the same along its supporting shaft.

3. A machine of the class described comprising a treating chamber having an inlet for feathers and a screened outlet in one of its walls, means for withdrawing air through said outlet to draw feathers into said chamber, means mounted in 5 said chamber and engageable with said screened outlet to prevent the accumulation or feathers thereon, and means for retracting said screened outlet engaging means from contact with said wall during a portion of its movement. lo

4. A machine of the class described comprising a treating chamber having an inlet for feathers and an outlet in one ci its walls, a screen mounted in said outlet, means for withdrawing air through said screen to draw feathers into said chamber, an arm rotatably mounted in said chamber and having a wiper portion enagealole with said screen to remove feathers acculatcd thereon, and a rib carried by said wali to be engages?. by said arm and to retract said Wiper por tion from contact with said wall during the partial rotation ci said arm.
