SPRA Y-PUM P.

SPECIFICATION forming part of Letters Patent No. 637,213, dated November 14, 1899.

Application filed February 23, 1899. Serial No. 706,532. (No model.)

To all whom it may concern:

Be it known that I, ISAAC W. NUMAN, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Spray-Pumps; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the figures of reference marked thereon, in which Figure 1 is a side elevation of a pump containing my improvements. Fig. 2 is a vertical longitudinal section. Fig. 3 is a view showing the top or upper end of the inner cylinder or barrel. Fig. 4 is a view showing the top or upper end of the pump proper in vertical section, also showing the stirrup or foot-piece connected thereto. Fig. 5 is a View showing the lower valve, also showing the connecting-flange. Fig. 6 is a View showing portions of the pump-barrels and illustrating the position of the valve leading from the working barrel to the air-chamber. Figs. 7 and 8 are detached views of the spray-nozzles.

The present invention has relation to spraypumps; and it consists in the novel arrangement hereinafter described and particularly pointed out in the claims.

Similar numbers of reference indicate corresponding parts in all the figures of the drawings.

In the accompanying drawings, 1 represents the outer cylinder, which cylinder is located around the working barrel 2, said parts being located and arranged substantially as shown in the drawings.

For the purpose of providing an air-chamber between the cylinder 1 and the barrel 2 the top or upper end of the cylinder 1 is closed by means of the collar or cap 3, which cap or collar is arranged substantially as shown in the drawings. The collar or cap 3 also provides a means for holding the top or upper portion of the barrel 2 in proper relative position. The bottom or lower end of the cylinder 1 is provided with the strengtheningband t and the inlet-apertures 5, said parts being located and arranged substantially as shown in the drawings.

The bottom or lower end of the barrel 2 is held in proper relative position by means of the disk 6, which disk is provided with the cup 7, and into which cup the bottom or lower end of the barrel 2 is seated substantially as illustrated in Fig. 2. a

At the bottom or lower end of the barrel 2 is located the valve 8, which valve is provided at its bottom or lower end with the rubber disk 9; but it will be understood that any other suitable material may be used in the manufacture of said disk 9, as the only object to be accomplished is to provide a perfect working valve.

For the purpose of connecting the disk 9 and the valve together the screw 10 is provided, which screw is passed through the opening 11, as illustrated in Figs. 2 and 5, said screw being provided with a head or eye, so as to prevent the valve 8 from being carried upward during the upward stroke of the plunger 12 except a sufficient distance to allow water to pass the valve during the upward stroke of the plunger.

The delivery-tube 13 is located substan tially as shown in Fig. 2, and, as shown, it extends to within a short distance of the bottom of the air-chamber 14 and is extended upward and beyond the upper end of the barrel 1, and its top or upper end is turned at an angle, so as to provide a means of easily attaching the hose 15.

For the purpose of providing an escape for any water that may find its way above the plunger 12 the drip 15 is provided, which drip is open at its bottom or lower end and, as shown, it is connected to the barrel 2 and the cylinder 1, and the passage 16 being provided between said drip and barrel 2, thereby allowing the water to find its way through the drip 15.

The plunger-rod 17 is constructed in the ordinary manner, and its top or upper end is provided with the ordinary handle 18, which may be of any desired form.

The plunger 17 is held in proper relative position by means of the stopper 19, which stopper is seated into the top or upper end of the barrel 2, by which arrangement the top or upper end of the barrel is properly closed.

Forlhe purpose of providing for the expan sion and contraction of the stopper 19 by reason of its contact with Water and then becoming dried the top or upper end of the barrel 2 is provided with the slit 20, which allows the barrel to expand with the stopper, which stopper is preferably made of wood. For the purpose of closing the barrel 2 at its top or upper end as the stopper contracts the springring 21 is provided and is connected in any convenient and well-known manner to the barrel 2, said spring-ring being so tempered that it will hold the stopper at all times and under all circumstances.

For the purpose of holding the pump proper in an operating position the stirrup or footpiece 22 is provided, which stirrup or footpiece is preferably formed of a single piece of material, its top or upper end being bent over and connected a short distance below the top proper, as illustrated in Figs. 1 and 4, by which arrangement the foot-piece proper is held a short distance away from the pump proper, so that said stirrup or foot-piece can be placed upon the outside of a pail or other vessel into which the pump is to be placed.

For the purpose of providing a means for allowing the water to pass from the barrel 2 into the air-chamber and enter the deliverytube 13 the valve 23 is provided and is located at the bottom or lower portion of the pump proper. The valve 23 consists of a ball and is inclosed in the conical cup 21L, which cup is attached to the barrel 2. For the purpose of properly inelosing the valve 23 and at the same time allowing for the movements of the valve the chamber 24 is provided,which chamber is shown partially broken away in Fig. 6. It will be understood that a cap, such as 25, should cover the chamber 24, which cap is held in place by proper screw-threads and is to be removed only when it is desired to drain the pump.

For the purpose of preventing the ballvalve 23 from becoming accidentally displaced during the time the cap is removed a bar, such as 26, extends across the outer end of the chamber2-l. For the purpose of providinga pump that can be used for different purposes the attached to the nozzle 27.

outer end of the nozzle 27 is provided with the

removable tips

28, 29, and 30, which tips are connected together by means of their disks 31, which disks are formed of such a size that the tips will be held a sufiicient distance apart to allow any one of said tips to be Each tip is pro vided with a different-shaped aperture, by which arrangement said tips may be used for different purposes, such as throwing a solid stream or spraying.

It will be understood that by connecting the different tips together and arranging them as shown the tips not in use will be out of the way and at the same time can be easily connected after the one in use has been detached, it being understood that the screwthreaded portions of the different tips are to be of the same size, so that they will be interchangeable.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination of the cylinder 1, a barrellocated within the cylinder, a plunger located within the barrel and a valve located below the plunger, said barrel provided with a drip at its upper end and a spring-ring located around the barrel and the stopper 19, substantially as and for the purpose specified.

2. The combination of the cylinder 1 and the barrel 2 located within the cylinder and provided with a plunger, the disk 6 provided with the cup 7, the valve 8 located in the bottom or lower end of the barrel the disk 9 and the screw 10 extended through the opening 11 formed in the disk 6, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
