This invention relates to improvements in primers for centrifugal pumps.

L ly present improvements are espeeiall deslgned by mefor use in connection 5 my pump attachment for motor vehicles shown in m application for Letters Patent filed Decem r 7, 1923, Serial No. 679,236 and I have illustrated the same as in practice in such apparatus. My improve. 1

1 ahird, to provide an im rov'ed I means of the class descri which requires no attention on the part of the operator'and is not likely to become inoperative or get out of repair when in use.

Objects pertaining to details and econao omies of construction and operation definitel appear from the detailed description to ollow. p I accomplish the objects of my invention by the devices and means described the as following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention ifiacl'early fillustrated in the accompanyin wmgs' orming a 40 part of this applicatfim, in which:

mnm nmnntndn ini m the to 1 re resents a tractor y and 2 the engi1a thereof.

-The intake manifold 8 of the engine is,

shown in conventional form.

The mi: 4 is an intake ban 'dis lhai ge 6. pump is mounted upon the tractor by means of the supportmglframe 7, the frame illustrated 'be mg that own in my above mentioned apphcation.

I provide a float chamber 8.which is connected to the interior of the pump b means to the bottom of the float chamber and'to the pump at a central point. The. top of the float chamber is connected to the in manifold by the conduit 10.

rovided an The float 11'has a stem 13 guided by the guide 14 at the bottom and in the p 15 m the top 16 of the float chamber. passage 150 0 into the chamber and also .to the outsi e thereof. It is provided with

valve seats

17 and 17 for'the valves 18 and 19carried by the stem 13 and adapted to seat alternately, that is, when the suction valve 18 is closed by the raising of the float, the-vent valve 19 is opened and vice versa.

The conduit is connected to this passage by a passage 20 formed in the top 16 and having a valve seat 21 therein for the ball check valve 22. This insures the maximum lift in the primeras the valve seats effectively with each impulse and a steady vacuum is maintained.

With the arts thus arranged, the opera: tion is as oHows: When the engine is started the suction in the intake manifold will draw the air from the'pump and the suction line, of course, that the line is at that time sealed by water, water is carried up. into the and into the float chamber, e oat and closing the valve 18, thus prevent' ing drawn into the engine. e vent valve 19 is opened so that air is drawn from the outside into the engine through the conduit, the main object of this however, being to prevent the valve being hung up by the suctionin the' event that the water should be drawn from the float chamber.

' The check valve 22 is provided to prevent the water bean outlet in its up a backward current pipe in theeventthatthesuctionwrthmthepump should be greater than'that m the intake manifold.

My improved primer is very eflicient and is m automatic in its operation. By the float chamber to the center of the pump the pump may be primed while the automatically e primin operation. For instance, should there be in the suction line or breaks in the suction admitthe pump does not the air is constantly exhausted while the pump is in o ration. This'also avoids the ty for a use of valve in the suction line, the pump primed without the use of such valve. valve 9! is. rovided in the conduit 10 after the pump has been rimed this conduit can be-manually closed, it is found that in practice it is not b 2; do this,
