PUMP SIPHON Filed Feb. ll, 1928 Iryveryfor d Burma Jr Patented Jan. 2s, 193e UNITED STATES JOHN BIB/NIE, JR., OF BIB-NIE, MANITOBA, CANADA :PUMP sIrHo'N Application filed February 11, 1928, Serial No. 253,763, and in Canada March 24, 1927.

The invention relates to improvements in pump siphons and an object or the invention is to provide a device whereby a liquid can be readily withdrawn from a container by a siphon action, the device being pro-vided with means for initially creating a vacuum to cause the liquid to flow.

A further object is to construct the appliance so that it can be manufactured at a comparatively small cost and such that it can be easily operated for the work in hand.

With the above more important objects in view, the invention consists essentially in the arrangement and construction of parts here 15, ,inafter more particularly described, reference being had to the accompanying drawing, in which Fig. l is a side view or the device in use.

Fig. 2 is an enlarged detailed longitudinal sectional view through one end ot the device.

F ig. 3 is an enlarged detailed longitudinal sectional view through the other end of the device.

Fig. 4 is a perspective view of the spider.

2rV Fig. 5 is a perspective view or' the plunger.

In the drawing like characters of reference indicate corresponding parts in the several gures.

It is very often desirable to discharge a liquid from a container' by the use of a siphon but at the present time, as rar as I am aware. no convenient method has been employed for initially extracting the air from the hose, pipe or such like used in order to create the `necessary vacuum to cause the liquid to flow,

According to my invention andv as herein disclosed, I employ a pump mechanism associated with the pipe, the pump being manually operated to extractthe air and lift the 4o liquid and then being placed in disuse whilst the liquid flows through the pipe in the usual siphoning manner.

In carryingout the invention, I utilize a piece of hose or other such llexible tubing l and into one end ot it, I insert a sleeve 2 such as a short length ot metal pipe and to this sleeve I attach as by screw threading, a cylinder 3. The lower end ot the cylinder is provided with an open centered screw plug 4 which provides a valve seat which is nor- 50 mally closed by a valve 5 in the nature of a toot valve.

Vithin the cylinder I slidably mount a plunger 6 of any well known type, the plunger being supplied with avalve 7 re- 55 tained by a cage 8. A pump rod 9 extends from the cage upwardly within the cylinder and terminates in aneye l0. The upper end of the rod passes slidably through a spider 11 and a spiral spring 12 surrounds the rod 60.

and engages the spider and the cage. rIhis spring functions to force the plunger downwardly and the spider serves to guide the pper end of the pump rod and prevent lateral shitting thereof. The sleeve 2 serves as 05 a rigid container guarding the upper end oi the plunger rod.

Here I might explain that if the end ot the plunger hose l were secured directly to the end of the cylinder as shown, the upper end of the valve rod might strike the hose when the same was bent and during the nianipulation ot the plunger. Y

Into the other end of the hose l I pass a sleeve 13, such as a length of pipe, this being v bound by say a wire 13, one end ot' the wire being extended to form a hook 18X for a purpose later described. The lower end of the sleeve 13 is adapted to receive aA plug or stopper 14, which is extended to provide a convenient hand grip l5. The plug is provided with a central passage 16 and to one end ot it, I attach a pulling line l? which is herein shown as formed from a short length of chain 18 and a wire 19. The chain is connected to S5 the plug by a pin 20 andthe end of the wire is connected to the eye l0 and passes through the hose. The handle end of the plug is sup plied with a tap or faucet 21 which is shown as screwed into the outer end of the passage 9o 16 and the handle is provided with an eye 22 whereby one can suspend the plug from the hook 13x when desired.

In Figure 1, I have hown the device as in use and in such ligure I have indicated a barrel 23 containing a liquid, some of which it is desired to discharge into the pail 24. In using the device, the plunger carrying end of the hose will be inserted in the liquid in the barrel and having done this, one will then grasp the handle 15 and pull it in order to pull the plunger towards the spider. I-Ie will then release the handle and the spring will ret-urn the plunger to the position shown in Figure 2. This action of alternately pulling and releasing the handle will cause the pumping of the liquid into the hose and when sufficient pumping has been done, the end of the hose carrying the sleeve 13 will be directed to the pail and the liquid will then flow from the barrel to the pail through the hose without further effort on the part of the attendant.

At this time, the handle can be hung on the hook 15. If one desires to discharge the liquid through the tap 21 he simply opens the tap and inserts the plug in the end of the sleeve in the manner shown in Figure 3 and the liquid will discharge through the tap instead of directly through the sleeve 13, it being understood that this will occur after the pumping operation has been carried on.

IVhilst I have entered into a detailed description of the various parts, I wish it to be understood that I do not desire to be limited to the details of structure shown as these could be readily modified without departing from the spirit of the invention as set forth in the appended claims.

; What I claim as my invention is:

1. A pump siphon comprising a length of flexible pipe, a cylinder attached to one end of the pipe, a foot valve at the free end of the cylinder, a reciprocating plunger operating in the cylinder and provided with a valve, aguided stem secured to the plunger, a spring pressing the plunger towards the foot valve, a flexible line connected to the stem and passing through the pipe, a hand grip connected to the pulling line, said hand grip having an outlet passage therein and being adapted to seat in the end of the pipe and a tap carried by the hand grip and controlling the flow through the outlet passage.

2. A pump siphon comprising a length of flexible pipe, a metallic sleeve entered in each end of the pipe, a cylinder carried by one of the sleeves, a foot valve located at the free end of the cylinder, a plunger slidably mounted within the cylinder and provided with a Valve, a stem extending centrally from the plunger and having the upper end thereof terminating in the adjacent sleeve, a spider guiding the upper end of the stem and butting the latter sleeve, a spring mounted on the
