METHOD OF PR ODUCING DISCHARGE HEADS AND HANDLE SUPPORTS FOR BARREL PUMPS Filed Jan. 30, 1950 2' Sheets-Sheet 2 INVENTOR. Few/1v. f? SU/VOHOLM F' 3, I BY Patented June 23, 1953 METHOD- F PRODUCING DISCHARGE HEADS AND--HANDLE SUPPORTS FOR BARREL PUMPS Edwin F. Sundholm, Albert City, Iowa Application J nuaryf'so, 1950, serial No. 141,259 r The present invention relates to a new and improved liquid-dispensing apparatus and more particularly to a barrel-pump for removing'lubrieating-fluid from a container such as a 55-gallon drum or the like.

The present invention relates more particularly to the method of. constructing the head,- portion or cap-portion of a liquid-dispensing apparatussuch as a barrel-pump.

An object of the present invention; is to provide a new and. improved method of manufacturing the. head-portion or cap-portion of a barrel-pump or similar; liquid-dispensing apparatus. An additional object of the present invention is:- to provideamethod of constructing the -head-portion of a liquid-dispensing apparatus such as a barrel-pump or the like which requires less cost, labor and time than heretobeforeused. I

, Further objects will be apparent by reference to. the appended specification; claim and drawings. I

For the purpose of illustrating the. invention, there is shown in the accompanying drawings one form thereof which is at present preferred, although it is to beunderstood that the various instrumentalities of which the-invention consists can be variously arranged and organized. and thattli'invention is not limited. to the precise arrangements and organizations of the instrumentalities as herein shown and described.

Referring to the drawings wherein like reference characters indicate like parts:

"Figure I represents a perspective view, partly insection, or the barrel-pump of'the present. invention as employed on a lubricant-container. V Figure 2" represents" a side elevational view, partly in section, of'th'e barrel-portion and capportion. of the'lubricant dispenser of the present invention supported on the headiof a lubricant container. 7

.Figure 3' represents a Vertical cross-sectional 1 Claim; ((31. 29-1564) ilar. to the pump. contemplated by the present invention is disclosed. in Sundhol'm Patent 2,344,005. Such pumps. may be. supplied to re- 1 tailers of lubricating fluid or to large-scale consumers of lubricating. fiuid;.said retailers or conto. dispense the fluid therefrom intermittently in View of the cap-portion of the barrel pump small amounts.

To facilitate the removal of the lubricant from the container, the barrel-pump contemplated by the present inventionImay be employed, which pump generally includes. a cylindrical barrel por: tion with reciprocatingpiston therein'secured to the drum-head at the bung-hole opening, with a riser-pipe extending into the container andiwith handle-means to operate the piston and with. a spout or conduit throughwhich the contentsof the barrel may be discharged.

In Figure. 1 thereis shown a pump. ID of the type contemplated. by the present. invention. This pump. includesa. cylindrical. barrel-portion l l which maybe screw-threaded at its lower end. l2 for engagement with. a bung-hole. adapter I3. Said bung-hole adapter may. be screwthreadedly secured in the bung-hole M in one end [5. of a lubricant container 16. A riser-pipe bottomof the lubricant-container. Appropriate valve means-such as a foot-valve (-not shown),

may be disposed in the lower end of. the riserpipe near the bottom of the; container l6-or at the upper end of the riser-pipe within the adapter. I3, through which lubricant may be drawn into the barrel-member ll.

A. piston I 9 is adapted. to fit slidingl'y fluidetight relationship within the barrel: H and to be reciprocated therewithin by the piston-rod 20; The upper end of. the piston-rod 20. extends out of the barrel. I I through the cap or head 2| and is secured, at its upper end, to the handle 22. The handle 22 may be joined by the link 23 i 7 cured to and extending upwardly and outwardly from the cap or head 2|. By means ofv the handle 22 and link 23, the piston-rod 20 and piston [9 may be reciprocated axially within the barrel It].

The cap or head 2| preferably is shaped and and. in

formed from a piece of sheet-metal into the cuplike body 53 with a flange 54 having screwthreads 33 adapted to receive the barrel ll therein, and having a central hole 29 at the upper end to receive a packing-gland '25 and with an aperture 31 on one side thereof to receive a spout The packing-gland '25 is secured to the cap or head 2l around the piston-rod to provide a sliding seal between the piston-rod 20 and the head 2|. The packing-gland includes a member 26 having a flange 21 and screw-threads 28. The

member 26 is adapted to fit within the aperture 29 in the cup-like body 53 with the flange 21 in contact with the outer surface thereof 7 The body-member 26 may be secured to the cup-like body 53 by brazing or soldering or welding or any other suitable means whereby to provide a fluid-tight seal between the body 53 and the member 29. The piston-rod 29 is adapted to pass through the hole 30 in the bottom of the member 25, and suitable packing-material 3| (such as a neoprene seal or fiber or jute washers or the like) in the member 28 is compressed by the nut 32 (which is engaged in the screw threads 28) around the piston-rod 20 whereby .to provide a fluid-tight yet slidable seal between the packing-gland 25 and the piston-rod 20.

' The cap or head 2| may be screw-threadedly secured to the barrel H as by the threads 33 with a gasket 34 providing a fluid-tight seal between the barrel ll and the flange 54.

A conduit or spout 35, having external screwthreads 36 at the end thereof adapted to" receive a discharge hose or the like (not shown), extends angularly upwardly and outwardly from the cuplike body 53 through the aperture 31 therein. The spout may be brazed or welded or soldered or otherwise secured in a fluid-tight fashion to the body 53.

The supporting-bracket for the handle 22 and the link 23 preferably is stamped or otherwise formed from one piece of sheet-metal into a pair of arms 4! and 42 having flanges 43 and 44, respectively, and-formed, at their juncture,- point, into the cylindrical bearing portion 45 which is adapted to receive the pivot pin 46 to which'the link 23 may be secured. The arms 91 and 92 may be reinforced by' the ridges 41 and 48, respectively, to provide an inexpensive sturdy and light-weight bearing-member or support-bracket for the handle 24.

The flanges 43 and 44 on the arms 4! and 42 according to the'method described herein produces a pump which is lighter in weight and hence easier to handle and less expensive to transport than barrel-pumps heretofore used.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore desired that the present embodiment I be considered in all respects as illustrative and may be projection-welded or spot-welded to the Y cup-like body-member 53 as at 49, 50, 5| and 52.

I have found that a barrel-pump can be manufactured quite inexpensivelywhen the pump-cap V or pump-headof the present invention is used therein. The sheet-steel cup-like body-member 53 may be formed much less expensively than cast-iron or cast-steel body-members heretofore employed and the bracket 24, being a pressedsteel one-piece member secured to the discharge} head 2| by the rapid and inexpensive projectionwelding method is much less expensive to fabrinot restrictive, reference being had to the appended claim rather than to the foregoing description to indicate the scope of the invention. Having thus described my invention, what I claim as new and desire to protect by Letters Patent'is the following:

" The method of producing a discharge head and handle-support for a barrel pump which corn prises pressing a cup from apiece of flat sheet-'- stee1,'cutting screw-threads on the inner surface of the lip of said cup, punching an aperture in r the center of the end wall of said cupanda second aperture in the side of said cup, bending a generally'J-shaped discharge spout from a onepiece tubular pipe, brazing the longer end of said spout in fluid-tight manner to said cup 'at' said second-named aperture with the bore'of said spout in communication with the interior of said cup, brazing a packing-gland tosaid cup at said first-named aperture,bending a one-piece generally V-shaped bifurcated bracket from flat sheet-steel to form a self-container pivot-bear ing at the root of the V and to formcup-engaging flanges at the ends of the V; and projection welding said bracket-flanges to the outer surface of the side of said cup opposite said secondnamed aperture.
