FLUID SPREADER Ult MAEKENG DEVICE.

Application filed. @ctober 4:, 1921. Serial No. course.

To aZZ whom it may concern:

Be it known that l, REGINALD Euro 01.- nnnnnsnxw, a subject of the King of England, residing at London, England, have invented certain new and useful Improvements in Fluid Spreaders or Markin Devices, of which the following is a speci cation.

llhis invention consists in improvements in or relating to fluid spreaders or markingdevices and refers particularly to spreaders for use with adhesives such as gum or to marking-devices for use with ink or fluids containing pigments.

An object of the invention is to afiord' a construction in which a simple, handy fluid container has spreading means combined with it.

According to the present invention such a device comprises in combination a tubular container having a closed end and perforations in its lateral wall in the region of that end, and a flexible member which is resiliently held against the outer Wall of the container to cover over the orifices therein, which projects beyond the closed end of the container, and which has preferably an irregularly formed or slitted end surface. Alternatively the end surface may be smooth.

Where reference is made herein and the context does not otherwise provide, the term irregularly formed end surface as applied to the flexible member, is to be understood to include any irregular formation or slitting of the end of the tube or the application thereto of arts such as bristles which grill give the e ect of an irregular end surace.

The purpose of the flexible member is normally to serve as a valve to close the oridoes; but when its free edge is drawn in contact over the surface on to which the fluid is to be spread the member is drawn away to uncover the orifices and to allow the fluid to pass down on to the surface over which it is spread by the member itself.

Conveniently, the flexible member is in the form of an elastic tube, sprung over the perforated end of the container; and in a preferred construction the perforated end portion of the container is an inner tubular part which is separate from and fits within an open end of the outer tubular container and is provided With an elastic or. flexible member which serves to close the space be tween the inner and outer tubular parts.

Some preferred forms of the invention will now be described in detail by way of example only with the aid of the accompanylng drawings in which Figure 1 shows mainly a longitudinal sec tron of one form of the device,

gigure 2 shows in perspective the spreader 7 Figure 3 is a similar view to Figure 1 of a modified form of device,-

Figure 4 shows in perspective a modified form of spreader,

Figure 5 is a sectional view of the end of the device with a modified form of spreader.

Figure 6 is a part sectional view showing a further modification in the form of spreader, and Y Figure 7 is a view similar to Figure 6 showing a modified form of the tubular end portion of the spreader.

Like reference numerals indicate like parts in several figures of the drawings.

In the construction shown in Figures 1 and 2 the container may be made of any a convenient material, such for example as metal or vulcanite and comprises primarily an open-ended container tube 1 of any convenient dimensions. One end of the tube is closed by a rubber or other plug 2 andsan end cap 3 and this end can thus, serve as the charging end through which the fluid can be introduced.

lhe other end of the container 1 is tapered by shouldering as shown and within it is inserted a short length of tube a of smaller diameter than the tapered end of the container tube 1 through which it is in sorted. The tube a is closed at its outer end and has perforations 5 in its lateral wall close to the closed end. Over the tube 4 is sprun a short length of rubber tube 6 which W1 1 cover over the orifices 5 and project slightly beyond the closed end of the tube 4c. The rubber tube 6 and the tube 4: can be forced together into the open end of the container tube 1 and thereby close the latter.

The outer circular edge of the rubber tube 6 is preferably slitted by means or radial slits 7 shown clearly in Figure 2. Alternatively, as shown in Figure 4;, the outer circular end of the rubber tube 8 may be formed with serrations 8 and either the slitted or serrated edge serves to aid in the spreading of fluid ever a surface to which the latter is to be applied.

The main container tube preferably provided with an air-inlet orifice near that end of it which is closed by the. plug 2 so as to permit the contained fluid to flow readily towards the opposite end. In the form shown the plug 2 is formed with an axial orifice 9 and the cap 3 isalso formed with an orifice 10. The cap 11 for the front end, which at times is put over the back end, has a central orifice 12 adaptedfor aligning with the orifice 10.

In the modified construction shown in Figure 3 the container-tube 1 is closed at one end with a rubber or other plug 2 which is covered by means of a cap but in this case there are no axial perforations similar to the perforations 9 and 10 of Figure 1. In the wall of the container-tube 1 is an orifice 13 and in the plug 2 is a groove or slot 14 extending to an opening at the inner end of the plug. Normally the slot 14 and orifice 13 are maintained out of register but when it is desired to use the device the plugfi can be rotated by turning the cap 3 (which can be knurled or fluted to give ones fingers good grip) to bring the slot 14 into register with the orifice 13, thus permitting air to enter the-back end of the containertube 1. The other or front end of the container 1 is not reduced in diameter as in the previous example but as before, there is inserted in it a tube 4 having orifices 5 with a rubber or other resilient tube 6 closing the space between the tube 4 and the wall of the container tube 1. In this exam 1e the outer end of the rubber or flexible tulle 6 is smooth, that is to say, it is not slitted or serrated.

In place of the rubber plug 2- a screw plug could be provided of any convenient material or a plain plug may be provided of material other than rubber.

In use it is found that the natural resilience of the rubber or similar tube 6 is sufiicient to close the orifices 5 under normal condltions, but if the projecting edge of the tube 6 is drawn in contact over a surface, one side of the tube will be dragged away from the tube 4 thereby uncovering some of the orifices and allowing contained fluid to flow out from the container through the orifices 5 on to the surface. The free edge of the tube 6 serves to smear the fluid over the surface and it is found that slits such as 7, or serrations such as 8, serve to aid in the even smearing of the fluid over the surface. i

It is' found that for certain fluids, such for example asink, the slits or serrations are unnecessary and a tube having a smooth end such as is shown in Figure 3 is quite i satisfactory.

In the modification illustrated in Figure 5-- nstead of the rubber tube 6 being formed with a slltted, serrated or plain end, it is provided with a plurality of groups of bris tles 15 or like independent bodies of other preferred material, as shown, the ends of which are let into the material of the rubber and are held in place by securing-wires 16. Thus the contents of the container 4 will flow as before to the orifices 5 and will escape therefrom when the bristles are moved over in contact with the surface to be coated, thus slightly drawing the material of the tube 6 away from the orifices. The bristles then serve to apply the fluid to the surface.

This construction is found to have great utility, for example in stencilling, or for application of colouring matter; although it is to be understood that the bristles may be employed when other fluids are to be used.

Figure 6 illustrates a construction of spreader in which the tubular container 1 is formed with an end portion 17 of reduced diameter. This end portion is screw-threaded into the body of the container 1, in order that it may be readily removed therefrom when desired. In this case the lateral apertures 5 are formed in the reduced end portion 17 in the region of the closed extremity of the latter. The tubular elastic member 6 which fits-over the reduced end portion 17 of the container is taper-ended as shown, the bore of the member 6 at its outer extremity being equal to the width of the line which the device is required to make when used as a marker. The extremity of the tapered end is serrated as in the previous examples.

In Figure 7 the construction of the end portion of the container is "exactly the same as in the example illustrated in Figure 6. In this case, however, the tubular elastic member is not taper ended.

The invention includes any flexible memher for covering the outlet orifices of the device provided that the member is such or is so resiliently held as normally to serve as a valve to close the orifices but to be capable of being moved away therefrom when its free edge is dragged over the surface upon which the fluid is to be spread.
