POURlNG-NOZZLE FOR SHEET-METAL CANS.

SPECIFICATION forming part of Letters Patent No. 437,232, dated September 30, 1890.

Application filed April 12, 1890. Serial No. 347,596. (No model.)

To all whom it may concern:

Be it known that I, EDWIN NORTON, a citizen of the United States, residing in May- Wood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Pourin g-Nozzles for Sheet-Metal Cans, of which the following is a specification.

My invention relates to pouring-nozzles for petroleum and other cans.

The object of my invention is to provide a simple, strong, and efficient construction of valve for closing the opening in the pouringnozzle, which may be easily and cheaply manufactured, and which will operate to form a certain and tight closure.

A further object is to provide a combined filling and pouring nozzle.

My invention consists in the novel devices and novel combinations of parts and devices herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, which form a part of this specification, Figure 1 is a side elevation of a device embodying my invention, showing a portion of the can to which it is applied. Fig. 2 is an enlarged central vertical section. Fig. 3 is a modification showing the application of my improved valve to a simple pouring or non-filling nozzle, such as is shown and described in my pending application, Serial No. 343,240, filed March 10, 1890.

In the drawings, A represents the can'or a portion thereof; A, its upper head, to which the nozzle is applied in the ordinary V-shaped cap -groove a, surrounding the opening A through the head.

B is the lower disk of the nozzle, which covers the opening A in the can-head and is soldered in place in the cap-groove a. This cap or nozzle disk B is furnished with a central opening B, through which the can may be refilled and out of which its contents may flow. Surrounding this opening B is a valve seat b, consisting, preferably, of an inverted groove stamped in the rim or edge of the metal surrounding the opening B.

C is a disk furnished with a screw-threaded sleeve at its inner or upper edge. This screwthreaded sleeve-disk C fits flat upon the cap or nozzle disk 13, and the two disks are secured together by folding the flange or edge of one over the other. The flange or fold b, which secures the disks B C together, I prefer to form on the lower disk B, as shown in the drawings. The act of soldering the cap-disk B in place in the can-head will also serve to simultaneously and securely solder the disks B O firmly together. To facilitate the soldering, I fold over the rim of the disks B C a solder annulus or ring E, so that the solder necessary for uniting the nozzle to the can is applied to the nozzle at the time of its manufacture.

D is a disk having a screw-threaded sleeve d, which fits or threads with the screwthreaded sleeve 0 of the disk C to form the removable screw-cap of the nozzle.

F and F are the upper or dome disks of the nozzle, the same being secured together and to the screw-threaded-sleeve disk D by afiange d on one of the two outer disks, which is folded over the other two. This securing flange or fold d is preferably formed or turned on the disk D. The removable screw cap of the nozzle is thus composed of the three disks- D, F, and F.

The disks F F, one or both, preferably both, are furnished with countersinks or pockets f to receive the screw-threaded valve-nut G of the screw-threaded valve-stem G". The disks F F are likewise furnished with countersinks or pockets f to receive the flange h of the pouring-nozzle H. The flange or fold d, which clamps or unites the disks F F together, thus also serves to rigidly secure in place the valve -nut G and the pouringspout H.

The valve consists of two disks K and K, having holes is, through which the valve-stem is inserted, and in the lower of which disks the valve-stem is securely soldered.

K is the packing or bearing surface of the valve, consisting preferably of cork or other suitable material. Where the valve-opening is large, as is ordinarily the casein arefilling and pouring nozzle such as is shown in Figs. 1 and 2, the cork disk or.packing K is preferably made annular or in the form of a ring to save material, and in such case the lower disk K is furnished with an annular offset 01' seat 70 to receive the annular packing. The cork or packing disk is firmly and rigidly secured in place by a flange or fold k turned over the same on the dome-shaped strengthening-disk I". This flange or fold k folding over the edge of the cork and embracing the intermediate valve-disk K, serves to rigidly clamp or secure the disks K K together, as well as to fix the packing-disk K in place. The domeshaped disk K serves to strengthen and brace the valve 011 the valve-stem, so that the valve will be held rigidly in a plane at right angles to the valve-stem and be strengthened so as to prevent the strains to which it is necessarily subjected in closing the valve-opening from breaking or loosening the solder-joint. By this construction, also, it will be observed that the soldenjoint between the valve stem and the lower disk is always exposed to view, so that the workman can by inspection readily see whether this solder-joint is tight, and at the same time there is no possibility of leakage around or through the Valve, as the cork disk K fits snugly against the intermediate valve-plate K and forms a tight joint therewith.

In the modification shown in Fig. 3 my improved valve, with the strengthening domedisk K, is shown as applied to the form of Valve described in my previous pending application before referred to. In Fig. 3 the corresponding parts are designated by similar letters of reference, the diiference being that the screw-threaded-sleeve disks 0 and D are both omitted and the dome-disks F and F thus secured directly instead of indirectly to the cap or valve disk B. In addition to this, of course, the valve in Figs. 1 and 2,being removable, is necessarily an upper 01' pushdown valve, while the valve shown in Fig. 3

- is a lower or pull-up valve.

G2 is the thumb-piece or handle by which the screw-threaded valve-stem is turned.

I claim 1. The combination of a valve-seat disk B with a valve-stem, a valve secured to said stem and consisting of a cork or packing disk, a sheet-metal disk on which said packingdisk is seated, and a strengthening or domeshaped disk having its rim or flange folded over the cork disk and clamping the two metal disks and cork disk together, said two metal disks having holes through which the valvestem is inserted and to the lower or under one of which said valve-stem is soldered, sub stantially as specified.

2. The combination, with a valve and a valve-seat disk B, having a valveopening B and a valve-seat b, of a serew-threaded-sleeve disk C, a screw-threaded cap-disk D, and dome-disks F F, one of said disks B and C being furnished with a flange folded over the other to secure the same together and one of said disks D and F being furnished with a flange folded over the other for securing said disks and the intermediate disk F together, said disks F F having clamped between them a flanged pouring-spout II, substantially as specified.

In a combined refillingand pouring nozzle, the combination of a valve-seat disk 1: having a valve-opening l3 and a valve-seat b, of a screw-t-hreaded-sleeve disk 0, a screwthreaded cap-disk D, and dome-disks F F, one of said disks B and 0 being furnished with a flange folded over the other to secure the same together and one of said disks D and F being furnished with a flange folded over the other for securing said disks and the intermediate disk F together, said disks F F being furnished with a valve-nut G, clamped between them, and a valve-stem and valve carried thereby, said disks F F having also a flanged pouring-spout II clamped between them, substantially as specified.

4. In a combined refilling and pouring nozzle, the combination of a valve-seat disk B,

having a valve-opening l3 and a valve-scat I),

of a serew-threaded-sleeve disk C, a screwthreaded cap-disk D, and dome-disks F F, one of said disks B and 0 being furnished with a flange folded over the other to secure the same together and one of said disks D and F being furnished with the flange folded over the other for securing said disk and the intermediate disk F together, said disks F F being furnished with a valve-nut G, clamped between them, and a valve-stem and valve carried thereby, said valve consisting of a packing-disk K and metal valve-disks K K, said valve-disk K having a flange k folded over said packing-disk K and said valvestem being soldered to the lower or under one of said sheet-metal valve-disks, and a spout, substantially as specified.
