MUCILAGE CONTAINER AND SPREADER Filed Dec. 15, 1930 2 Sheets-Sheet 2 Patented May 23, 1933 UNETED STATES LEONARD B. SKOGLUND, 0F FREMONT, NEBRASKA MUCILAGE CONTAINER AND SPREADER Application filed December 15, 1930. Serial No. 502,480.

v This invention relates to an improved mucilage container and spreader and one object of the invention is to provide a device of this character of such construction that a relatively large quantity of mucilage or paste may be stored in the container and fed from the outlet of a nozzle directly upon the surface to which it is to be applied.

Another object of the invention is to so form the container that the mucilage or paste may be stored therein above a flexible diaphragm, and this diaphragm urged upwardly by compressed air stored in the body portion of the container in order to force the mucilage or paste through a flexible hose and through a nozzle by means of which it is to be applied.

Another object of the invention is to permit a supply of paste or mucilage to be easily forced into the container without taking the container apart, thereby allowing the container to be easily charged when a fresh supply of paste is necessary.

Another object of the invention is to permit flow of paste or mucilage through the flexible hose to be shut off when the device is not in use, thereby relieving the hose from unnecessary strain and to also permit passage of the paste or mucilage to be easily controlled when the device is in use.

Another object of the invention is to so locate an actuating lever for the control valve of the nozzle that the lever may be adjusted by pressure of the hand grasping the nozzle, thereby making it unnecessary to use both hands in order to operate the nozzle.

The invention illustrated in the accompanying drawings, wherein:

Fig. 1 is a perspective view showing the improved device in use.

Fig. 2 is an enlarged sectional View taken vertically through the container.

Fig. 3 is an enlarged View showing the nozzle in side elevation.

Fig. 4: is a longitudinal sectional view through the nozzle.

Fig. 5 is a vertical sectional View taken through a portion of the container at rightangles to the view shown in Fig. 2, and

Fig. 6 is an enlarged fragmentary sectional view through the cover and lower end of the outlet valve.

The improved container and spreader consists briefly of a container 1 having a flexible tube 2 leading therefrom, and anozzle 3 at the outer end of the tube which is to be held by the operator as shown in Fig. 1 and by means of which themucilage or paste may be applied to the backing 4 of a photograph or any other surface to which it is desired to have adhesive applied. By referring to Fig. 1, it will be seen that the container is of sufficient size to hold a relatively large quantity of paste or mucilage, but at the same time may be easily lifted by its handle 5 and moved from one placeto another. Therefore, an operator mounting photographs in a photograph shop or gallery will have an ample supply of paste. While the device has been shown in use for applying paste to photographs, it will be understood that it may be used for applying mucilage, glue, or any other adhesive which may be forced through a tube and nozzle and the adhesive applied to any objects desired. j

The body portion or receptacle 6 of the container is preferably formed of strong metal and about its open upper end is provided with an outstanding annular flange 7 upon which rests marginal portions of a diaphragm 8 formed of rubber, leather, thin metal or any other flexible or pliable material suitable for the purpose. The cover 9 has the shape of a dome so that it projects upwardly from the receptacle, and has. a

flat marginal portion or flange 10 which rests upon the marginal portion of the diaphragm. Aligned openings are formed through the flanges 7 and 10 and also through marginal portion of the diaphragm, and through these aligned openings are engaged bolts 11 having nuts at their lower ends which when tightened will draw the cover into tight binding engagement with marginal portion of the diaphragm, and not only hold the diaphragm in place but also provide an air-tight joint between the cover and the receptacle. The handle 5 has its arms formed with hooks 12 at their ends engaged through openings in brackets 13 secured in opposed relation to each other by certain of bolts 11 and this handle is of such size that it may be swung from a lowered position to a raised position so that the container may be easily lifted by this handle and carried from one place to another. There has also been provided a tubular socket or nozzle holder 14 mounted in a vertical position at one side of the receptacle by having one of the bolts 11 passed through a lip 15 at the upper end of the socket or holder, and this socket is intended to receive the barrel of the nozzle in order to support the nozzle in a substantially vertical position close to one side of the receptacle when not in use.

The inner end of the flexible tube 2 is engaged with the outlet neck 16 of a valve 17 which has its inlet neck 18 screwed into a threaded opening 19 formed centrally of the dome and by an inspection of Figs. 2 and 5 it will be readily seen that by adjusting the valve, flow of mucilage or paste through the tube may be controlled. Therefore, the tube may be relieved from unnecessary strain when the device is not in use and also variation in pressure exerted by compressed air upon the diaphragm may also be compensated for by opening and closing of the valve when found necessary. The air is formed into the body or receptacle through a valve 20 engaged in a threaded opening 21 formed in the side wall of the body and since this valve is of the type used in connection with automobile tires, the pressure of the air in the body may be controlled. A safety valve 20' permits excess pressure to escape. This valve may be opened when filling the space between the cover and diaphragm with paste. A tube 22 rises from the cover and at its upper end carries a valve 23 having a threaded opening 24 in its upper end to be closed by a plug 25. By this arrangement the plug may be removed and the nozzle of a force gun which has been filled with paste or mucilage engaged in the opening 24 after which the valve may be opened and the paste or mucilage forced from the gun through the valve and tube 22 into the container. After the entire con tents of the gun has been forced into the container, the valve 23 may be then closed and the gun removed and the plug replaced or the gun again filled and additional paste or niucilage forced into the container if necessary.

The sockets of the cover into which the valve 17 and tube 22 are screwed each has its inner end portion reduced in diameter to form an annular shoulder 44 and the extreme inner end is flared to form a tapered seat 45 for engagement by a hollow shield 46. This shield is closed at its inner end by a head 47 and has a tubular shank the upper portion of which is bent to form a flange 48 adapted to rest upon the shoulder 44 and suspend the shield in the depending unseated position shown in Fig. 6. A. spring 49 confined between the flange 48 and a washer 50 against which the inner end of the valve 17 or tube 22 bears yieldably, resists upward movement of the shield and normally holds the shield in the position shown in Fig. 6 with the openings 51 in its shank uncovcred so that paste may pass through these openings. The shields remain open until their closed inner ends are engaged by the diaphragm. The shields are then closed and their heads 47 prevent portions of the diaphragm being forced into the inner ends of the openings in the cover and damaged. Pressure exerted by paste forced inwardly through the tube 22 is suflicient to depress the shield from its socket.

lVhen the container is initially filled the entire space between the sagging diaphragm and the cover is filled with the paste and air is enforced into the receptacle through the valve 20 until the pressure of the air is sufficient to urge the diaphragm upwardly in order to expel the paste from the container through the tube 2 when the valve 17 is open. Additional air may be forced into the receptacle through the valve 20 if found necessary and air may be allowed to escape from this valve in order to permit a fresh supply of paste to be easily forced through the filling tube into the container.

The nozzle at the outer end of the flexible tube 2 has a handle 26 formed at its outer end. with a head 27 from which extends a barrel 28. A passage 29 is formed longitudinally through the handle as shown in Fig. 4 and communicates with a passage 30 formed longitudinally through the barrel. Therefore, the paste may pass through the handle and barrel. At the forward end of the barrel is provided a tip 31 which is threaded into the barrel and this tip has its bore 32 tapered towards its outer end, thereby forming a valve seat 33 against which is adapted to seat the tapered forward end of a rod or needle valve 34. This rod extends longitudinally through the barrel and the head 27 at the outer end of the handle and passes through a gland 35 which is tightened to compress packing 35 and forms a tight joint at the rear end of the head. A lever 36 which is pivoted upon a pin 37 carried by arms 38 projecting from the handle 26, has its forward end formed with an opening 38 through which the rear end portion of the rod 34 passes and disposed between an abutment collar 39 and nut 40 carried by the rod. The collar 39 may be formed rigid with the valve rod, or stem,

but the nut 40 is threaded upon the stem in order that it may be removed when nec essary and also to permit it to be adjusted and permit the lever to have the necessary swinging movement about its pivot in order to shift the valve stem longitudinally and move its tapered forward end into and out of engagement with the valve seat of the tip 31. A spring e'l disposed between the handle and the lever end engaged about lugs 42 and 43 carried thereby yieldably holds the lever in its normal position shown in Fig. l in which the valve stem or rod is in the seat or closed position and returns the valve to the closed position when pressure upon the lever is relieved.

lVhen this apparatus is in use the space between the diaphragm and the cover is filled with paste or mucilage and air is then forced into the receptacle or body through the val e 20. The valve 17 is opened and paste will be forced through the tube until the tube and the handle and barrel of the nozzle 3 are filled. The operator grasps the nozzle by its handle and by applying pressure to the lever, the valve stem or rod 34 will be shifted rearwardly out of engagement with valve seat 33 and the paste or mucilage will be forced through the bore of the tip 31 onto the backing of a photograph or other surface to which the adhesive is to be applied. If it is found that the pressure of the air in the receptacle or body 6 causes the paste to feed from the nozzle too freely, the valve 17 may be adjusted towards a closed position until the paste flows from the nozzle at the desired rate of speed. hen the supply of paste in the container becomes exhausted, it is merely necessary to remove the plug 25 and apply a filled gun of the grease gun type. lhe valve 23 may then be opened and a fresh supply of paste or mucilage forced through valve and tube 22 into the container. If so desired this filling operation may be performed at determined intervals, thereby preventing work of an operator being interrupted by the supply of paste in the container becoming exhausted.
