DISTBIBUTING DEVICE FOR MOVING FLUIDS AND GASES.

Application led December 12, 1924. SerialfNo. 755,582.

To all whom t may concern:

Be it known that I, GEORGE JAMES MAN- soN, a subject of the King of Grreat Britain, and resident of the town of Hawkesbury, in the Province of Ontario and Dominion of Canada, have invented lcertain new and useful Improvements in Distributing Devices for Moving Fluids and Gases, of which the following is a specification.-

o This invention relates to improvements in distributing devices for moving fluids vor gases and the objects of the invention are to provide for more uniform lateral distribution of agas or fluid current across thewidth of a moving sheet or the like which is to be dried, whereby the moving current`or blast would be uniform in intensity and velocity throughout the width of the material being operated upon. rfhe device is particularly applicable to the extraction of moisture from and the drying of moving sheets, felts or boards of fibrous material suchv as paper, pulp or fibre-board or the like.

Further objects of the invention still are generally to improvenand simplify a device.

of this' character to enable it better to perform the functions required of.' it.

The invention consists essentially of the improved construction hereinafter described in detail in the accompanying specification -and drawings and more particularly pointed out in the claims.v f i Figurel is a plan view of an embodiment o f my invention partly broken away, showing a plurality ofv distributing devices in operative position.,

Figure 2 is a section on'the line 2-2 of Figure l. A

Figure 3 is a cross section to an enlarged scale on the-line 8 3 of Figure 1.

Figure 4 is a section on the line 4--4 of Figure 3. y l

In thedrawings like characters of reference indicate corresponding parts in all the Referring to the drawings, A indicates one, of my .improved distributing members which may be operated either as a blast or suction distributor. It is provided with a gradually convergingl distributing channel 10 conveniently formed with parallel upper fand lower plates 20 and 21 and an inner side plate 22 and an outside plate 23,`the latterl gradually converging towards the `plate 22, as indicated in Figure 4f.4 VThe inner plate .22is formed with a plurality of spaced ports v material to be dried.

11 extending substantially from bottom to top of the channel 10 and opening into a plurality .of cross channels l2, greater in ywidth than the ports themselves and designed to. conduct the gas or fluid `to a common outlet or channel 13 which may be formed more or less in the form of a noazle withy curved edges 15\ and 16 designed to discharge or draw in the gas or fluid`in a,

tangential direction in respect to the moving sheet. The cross channels 12 may be conveniently formed from vthe material` struck out from the ports 11, such material constituting cross partitions 24C by which the crossl channels are formed, the outside `of the cross channels being formed by a suitable plate 25 having La flange 26 by which it may be attachedto the plate 21.

rllhe various plates and channels may be formed of any convenient material, such as sheet iron, or steel, which is suitably shaped and formed in the various channels and cross channels, as indicated, and held together by any convenient fastening means such asspot welding or riveting.

In using the device to dry a Vmoving sheet of pulp or fibre-board B or the likegcarried on suitablecndless conveyors C, I preferably provide a plurality of pairs of distributing devices A1 and A2, Bl and B2, the part A1 and A2 being opposed in direction to each other and located abovethe sheet 'while the pair B1 and B2 are opposed to leach other andlocated below' the sheet. Each of these distributing devices is similar in construction to the deviceI A already described and the devices of each pair are preferably connected Iby a guide or deflectlng plate D which guides theair yor fluid ih its passage from one device to the other and retains it in. contact with the sheet of ling operating the device to extract the moisture froma sheet of libre-board, which for instance may have come from the usual wet Ymachine, the drying air, preferably heated, is introduced through the devices A1 and B1 while the sheet is carried at a suitable-rate on Lthe convey'orqC. The air,passes at al suitable velocity, governed by the speed at which it is desired to have the drying operation take place, from the devices A1 pickup moisture from the sheet to be Ldried and a suitable suction will-be created within v the devices A2 and B'da causing the moisture A s livered from the cross channels and is then combined when discharged. lln combining the direction of the current is changedI to thereby insure the effective combination and' commingling of the various currents passing through the cross channels. It will also be noted that a current of air or gas or fluid is discharged tangentially through the surface of the material lto be dried and may move either with orfagainst the direction of the movement of such material.

llt will be seen that the tapered or gradually converging arrangement of the inlet channel 10 of the device will, taken together with the ports 11 in one side thereof, enable a uniform distribution 'of' the drying current to be made whereby all parts of the sheet to. be operated uponwill be uniformly treated.y

As many changes could be made in the above construction and many apparently widely` different embodiments of my invention within the scope of the claims, constructed without departing from the spirit or scope thereof, 1t is intended that all matter contained in the accompanying vspecification and drawings shall be interpreted inan illustrative and not in a limit in'g sense.l

What I claim as my invention is: f 1. A distributing device for moving fluids or gases comprising a gradually converging channel having a plurality of spaced ports in the side thereof, cross channels communie eatingV with the ports and arranged to discharge or take in together to produce a uniformly distributed flow.

2. The combination with the device as claimed in claim l, ofa nozzle member kthrough which the cross channels discharge.

3. The device as claimedl in claim 1 in -which the distributing device is rectangular in cross section.

I4. A distributing device for the purpose specified comprising a distributing channel, a plurality of cross channels opening into the same, a common channel opening from the cross channel, said common channel having a suitable outlet nozzle.

5. The combination of one .or more devices as claimed in claim 1 of a moving conveyor designed to carry the material to be operated upon by the fluid or gas distributed by said device or devices.

6. -Theherein described means for distributing a moving fluid or gas which comprises means for drawing` successive lateral currents from a gradually convergingcurrent of gasor fluid, means for then combining these-lateral currents, and means for changing the direction thereof, and discharging the same. Q

7. The means as claimed in -claim 6 in whichthe .current is discharged tangentially of the surface to be dried. I l

8. The means as claimed in claim' G in which currents are caused to flow above and below the material to be dried.

9. 'A distributing device for the purpose z specified comprising a distributing channel, a pluralityof lateral channels` communicating with same', designed to discharge together to thereby combine the currents and means for directing the combined currents from the common channel tangentially of the material. to be dried.

l1. A drying apparatus of the character described comprism@ a conveyor, a pairof opposed distributing devices on one side of the conveyor, said devices including means' for. uniformly distributing the current of fluid or gas transversely across the material to be dried and a guide plate extending be- Itween the two devices.

12. A device `as claimed in claim 11 in which one pair of devices is arranged above r the material to be -dried and a second pair is arranged below the material to be dried, whereby both surfaces of the material to be Adried are operated upon simultaneously.

13. A distributing device for moving gases or fluids comprising a graduali con-f verging channel having a plurality o ports therein and cross channels communicating with the ports and being of greater width than the same, and being arranged to discharge together.

14. The herein described methodffof drying a moving sheet of material which comprises passing uniformly distributed currents of air tangentially and simultaneously along both surfaces of the material to be dried.

15. A distributing device of the character described comprising a channel having con- `verging walls', one of said walls havin a plurality of ports therein, and a pluraityl of cross channels communicating. with the ports and having a `common discharge.

' 16.
