his invention relates to improvements in or connected pneumatic apparatus or means for conveying from bale breaker (or anyoth'er opener or 'fe-eaer) and treating te'zztil'e fibers for delivery to stack miizings and wherein a series of condensers or such like are used along with a pneumet-ic fiber tonveying arrangement involving the use at ee'nnee'tea pipes.

According to our invention we arrange to interconnect a series of condensers or equivalent apparatus, by pipes or. trunks in such a amet-ha any condenser in the series can be but out "or reinstated and, when a amen-set is cut but, the fiber no longer passes through the cut-oiit condenser. Fur-V ther the arrangement is such tlia't'conn'ect ing pipe'sjof a uniform or standard diameter' can be used. Also the condenser or equivalentapparatus is constructed in manher to suit the end in view and a revolving stripper suifi'ciently seals the delivery outlet from each condenser where the fiber is de-' posited upon the fioor of the mixing room or otherwise placed. p

According t'o our invention we use an arrangeinefit of pipes passing along one side of the combined or grouped condensers and with suitable connections to the condensers the piping being fitted with valves or dampers to allow the Cotton or other fibrous material to go through any condenser or to pass by same to any other condenser where more than one is used, that is, Where more than one additienal mining is provided This allows any condenser through which fiber is iiottto be passed for the time being, to become inective and completely efut out and permits of a uniform diameter of con necting pipe throughout the whole system irrespective of the number of condensers in theconibination. q V V The "washed drawings adequately illustrate our improvements, and, in such drawin s:-

similar to Fig. 1, but with a modified control gear and'other detail features.

Fig. 5 is a plan of Fig. 4.

Figs. 6 and 7 are sideelevation and plan where the fibrous material can only pass into the last condenser 01' a series and the terminating side pipe for the condenser leading to the fans can only convey the dust and dirt, the fiber itself being delivered by the condenser. v

In the drawings, each condenser as a whole is marked A and comprises a. perforated revolving cage (1 With. known suction e g g heet a" and a revolving strip- P g roller 6. These devices are indicated being driven by chains and sprocket Wheels from the driving shafts 0 but this is not material.

e provide two control valves in connection with each condenser A or the like the valves being fitted (Fig. 1 and 2) with movable dampers such as d," e, and the dampers are connected together by a rod f and pivoted levers g, h actuated by hand for example through another rod 2' from a fulcrumed lever y or part fixed in any suitable position inside or outside the cotton mixing bins. One such actuating arrangement is clear fronrFigs. 2 and 3-. A modified form is shown in Figs, 4 and 5 'Wher'e'a bell-crank lever it moved by pendent chains k actuates the rod f. A weight device may be provided to ensure effective closing of the dam ers. i

The damper d of one valve is so constructed and arrangedas to allow the fiber topass onto the perforated revolving cage 2 of the cehaeh'ser'nem which it is delivered into theinixing bin by means of a revolving stripping roller 7), to be later mentioned, or said damper can be set to cause the fiber to pass albng a side pipe 'm and pipe connection m te a second or successive condenser A.

The damper e ef the other valve is so constructed and arrenged and is operated at the same time by the interconnecting gear already described, as to in one case allow for the assageefair through an end opening a in the perforatedrevolviiig cage (2 to the connectin ipe m when fiber is being passed condenser t6 the mixing bins,

or in the other case to shut off the end opening from the perforated revolving cage to the connecting pipe when the said cage in the condenser to which the connecting pipe is attached becomes inactive.

Thus, a passageway for the pneumatic conveying of fiber can be opened up through any linked or combined condenser or any condenser can be cut out at will and the fiber passed along the side pipe m and connecting pipe m to another condenser in the series so that the conveyed fiber does not traverse or pass through the cut-out condenser. In the latter case the damper d is shut to condenser A and the damper c is open in connecting pipe m as indicated by say Figs. 1 and 2.

In connection with the perforated revolving cage or equivalent in the condenser we use a revolving stripping roller 7) and this has arms or wings or extensions arranged on its periphery which carry flexible flaps b the latter contacting with a shaped cover or parts of a casing b in such manner that two of such flexible flaps one on either hand always contact with the cover or casing. Said cover or casing forms the delivery chute and prevents an intake of air and any subsequent interference with the delivery of the fiber to the mixing bin. The perforated revolving cage and the revolving stripping roller each rotate in the same direction, this being the direction of the fiber to and on the perforated revolving cage.

A number of rods, bars, plates or louvres fixed or adjustable may be placed in a vertical or other position and staggered (or otherwise arranged) intermediate of the side pipe and connecting pipe and between the valves of the last condenser of a series to prevent any large bulk of fiber reaching and passing through the exhaust fan to the dust outlet in the event of all the valves of the series of condensers being inadvertently left open to the side and connecting pipe. We show the application of three staggered vertical bars in Figs. 4 and 5 for this purpose, the same being marked k.

We may, as shown by Figs. 6 and 7, omit the valves and dampers of the lastcondenser of a series and join the connecting pipe 1V between. the last two condensers of a series directly onto the perforated revolving cage inlet of the last condenser of a. series, so as to exhaust the air through the end a? of the perforated cage on one side only of the last condenser of a series by means of a connecting pipe m coupled to an end compartment placed over the side opening from the perforated cage, the pipe m leading to the exhaust fan. This would be done to prevent fiber travelling to the fan and choking same and would mean that the .fiber would be delivered by the last condenser and the dust and dirt only would travel on due to the action of the fan. This provision would prevent cotton or fiber going direct to the fan in case an operative left the valve or damper in connecting pipe open accidentally and such an arrangement would entail the constant running of the last cage and stripper.

We declare that what we claim is:

l. Pneumatic apparatus for conveying textile fibers to mixing bins, comprising a plurality of condensersv each having a. perforate cage, a damper in said cage, a single revolvable stripping device co-operating with the cage and revolving in a casing, a two-sided outlet cover to the casing, flexible flapson the revolvable stripping device, the flaps contacting with the two sides of the outlet cover to seal same, feed pipes of uniform sectional area combined with the condensers and disposed at the side thereof, and an arrangement of two valves inconnection with the side pipes, whereby any; condenser can be cut-in or cut-out by manipulation of the two valves so that in one case the fiber is delivered by a particular condenser and in the other case the material continues along the side pipes and is not passed over the condenser cut-out, and a fan to create a suction through the connected structures.

2. A pneumatic apparatus for conveying and for delivering textile fibers where required, comprising a, plurality of conden-.

sers, the condensers having perforated cages, dampers in the cages, each of said condensers having a delivery outlet, two shaped faces to the delivery outlet, a combined stripping device revolving in the same direction as the cages and havingflexible flaps and revolving in a casing forming the delivery outlet, the flexible flaps acting upwards on and stripping the perforated cage and working to the shaped faces to seal the outlet from the condenser, valve structures com prising two valve devices located in the feed pipes of uniform sectional area all in such. manner as to permit any condenser to be cutin or cut-out by manipulation of the two valves so that the material is delivered by a particular condenser or in the other case the material is not passed at all through the condenser cut-out, and means for creating a suction along the pipe at the last condenser.

3. Pneumatic conveying apparatus for textile fibers whereby the fiber is carried and deposited as required, comprising a plurality of condensers each having a perforated cage, a damper in each cage and a delivery stripper consisting of a rotatable device with fiexible flaps rotating in a casing and in the same direction as the cage, shaped covers to the casing, side pipes of uniform sectional area leading to and from each condenser, two valves in the piping for controlling the operation of said side pipes, actuating means for the valves, and a suction device at the end of the side pipes whereby when a condenser is cut-out no material passes into the condenser structure but passes along the side pipe.

4. Pneumatic conveying a paratus for conveying and delivering texti e fibers, such as cotton, to mixing bins, comprising condensers combined together by side pipes of uniform sectional area which interconnect the condensers, each condenser having a perforated cage and a damper, and a stripping device consisting of a revolvable structure With flexible flaps rotating in the same direction as the cage and working to a casing,

mg of the outlet, two valves on the side pipes which close and open ingress to the condensers whereby when a condenser is cutout no material passes through it, and a fan to produce a suction at the last condenser.

In testimony whereof we have signed our names to this specification.
