JOHN H. KINEALY, 0F FERGUSON, MISSOURI.

PUMP DEVICE.

T 0 all whom it 712 1;2 concern Be it known that I, JOHN H. KI EALY, a citizen of the United States, residing at Ferguson, in the county of St. Louis and the State of Missouri, have invented a new and useful Improvement in Pump Devices, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to that class of pump devices in which the fluid to be pumped is induced to flow into the device because of a vacuum produced therein by the condensation of steam and the fluid to be pumped is made to flow out of and away from the device because of the pressure created therein by the introduction of steam.

My invention relates especially to pump devices used in connection with heating systems for the purpose of withdrawing the air from said systems so as to make it easier for steam to circulate through the various parts of said heating systems, and also to enable the steam to be circulated through said sys tems at a pressure less than that of the at mosphere.

The object of my invention is to provide a device that will comprise no parts that can be easily deranged or that will require any special care or attention, and also to provide a device that may be operated with steam at a low pressure.

My invention is fully shown in the accompanying drawings where similar letters are used to designate similar parts.

Figure 1 is a view showing the device part in elevation and part in section, and connected to the air line of a heating system; Fig. 2 is a sectional view showing a part 01": the valve operating mechanism in elevation; Fig. 3 is a sectional view of Fig. 2 along the line 3-3; and Fig. 4: is a sectional view of Fig. 2 along the line 4-4;.

Referring to the figures, A is a closed tank forming a primary vessel and B is a second tank connected to the tank A by means of the pipe or nipple C.

D is a leg having at its upper end a box E connected at its lower end to the tank B by means of the pipe F.

Specification of Letters Patent.

Application filed September 23, 1912.

Patented June 3, 1913.

Serial No. 721,813.

G is a pipe or nipple connecting the upper part of the box E to the tank B.

The tank B with the box E and the leg D form what may be called a secondary vessel.

The box E is provided with a removable cap or cover E and the tank B is provided with an air valve L. This air valve L is adapted to allow the flow of air or of steam from the tank B when the pressure therein is greater than that of the atmosphere, and to prevent the flow of air into the tank when the pressure therein is less than that of the atmosphere. The valve is not shown in detail because it is of a type whose construction is old and well known.

J is the air pipe by means of which the device is connected to the heating system, and it serves as a suction pipe through which the air drawn from the heating system passes into the primary vessel A. The pipe J is provided with a check valve M which allows the passage of a fluid into the vessel A, but prevents the passage therefrom.

K is a discharge pipe through which any fluid pumped into the primary vessel A is discharged, and it is provided with a check valve N which prevents the passage of any fluid into the vessel A through the pipe K.

H is a steam pipe through which steam is conveyed from any suitable source of supply to the device, and I is a water pipe by means of which water is conveyed from a suitable source of supply to the device.

0 and P are valves by which the flow of water and steam from their respective pipes into the apparatus is controlled. These valves are similar in construction and comprise a body portion having a seat 0 and p in the valve 0 and P, respectively.

0 and 79 are valve pieces adapted to .rot-ate on the seats of the water valve and the steam valve respectively, and z" and i are valve stems attached to the valve pieces of the water valve and the steam valve respectively. The valve stems rotate in and are carried by tubular braces 7' and j of the steam valve and water valve respectively. These braces extend inside of the box E, and that of the water valve is threaded on its inner end and has engaging with the thread ed portion a nut Z which has a beveled portion Z that can be screwed up close to the inner end of the water valve so that the water passing through the valve into the box E is made to enter the box in a spray or finely divided condition.

The seats 0 and p of the water and steam valves respectively, are provided with perforations w and the valve pieces 0 and p are provided with perforations 00 which are adapted to register with the perforations 00 when the valve is opened as is shown in the case of the valve P in Fig' 2, and when the valve is closed the perforations w in the valve piece do not register with the perforations as in the valve seat but are somewhat in the position shown in the case of the water valve 0 in Figs. 2 and 4.

The valve stems i and i have attached to them at their inner ends arms 76 and respectively, which are adapted to engage with the U-trips m and m, respectively mounted on the outer ends of the pin or shaft h.

e is a trip-rod mounted on the pin or shaft h and adapted to oscillate about the center of this pin as an axis and to carry the pin and the U-trips m and m with it.

(Z is an overweight mounted on the trip rod 0.

s are set-screws by which the arms is and is and the U-trips m and m and also the trip-rod e are held in position on the valve stems and j and the pin or shaft it, respectively.

a is a float carried on the rod f which is mounted on the pin or shaft Z) and which has on the end opposite to that to which the float is attached a counterweight c.

g and g are arms, preferably made integral with the arm f, adapted to engage with and move the trip-rod e.

The pins Z) and h are mounted in bearings carried by the supports 1* which are fastened tothe lugs t formed on the sides of the box E.

u is a link by means of which the bucket o is attached to the underside of the float a.

When the float a and the trip-rod e are in the position shown in Fig. 1 the steam valve P is closed and the water valve 0 is open so that water can pass from the water pipe into the box E; and when the float a and the trip-rod e are in the position in Figs. 2 and 3, the steam valve P is open and steam can enter the apparatus, but the water valve 0 is closed. When steam enters the apparatus it passes from the box E through the nipple G into the upper part of the tank B and there acts upon the air and the water in this tank. The pressure of the steam opens the air valve L and makes the air pass out therethrough; and the pressure of the steam exerted upon the surface of the water in the tank B and in the box E forces this water from the secondary vessel through the pipe 0 into the tank A. and when the water has been depressed in this secondary tank until its surface is as indicated by the line 3 -g in Fig. 1 the weight of the water in the bucket 11 will actupon the float (I. and the rod in such a way as to make the trip-rod 6 move from the position shown in Figs. 2 and 3 to that shown in Fig. 1, thus closing the steam valve and opening the water valve. Then water will pass from the pipe I through the valve 0 past the beveled surface Z of the nut Z and enter the box E in a sprayed or finely divided condition, and this water coming in contact with the steam in the box E will condense this steam and create a partial vacuum whereby steam will be drawn through the nipple G- from the upper part of the tank B into the box where it will be condensed. In this way the pressure in the secondary vessel, comprising the tank B the leg 1) and the box E. will be made less than that of the atmosphers and the air valve L will close and the water in the primary vessel will pass through the nipple G into the secondary vessel. The water in the tank B and the leg D will always stand at the same height because of the pipes F and G. As the *ater falls in the primary tank A a partial vacuum will be created above the surface thereof and this will cause air or any other fluid to pass from the pipe J through the check valve M into the tank A. hen the surface of the water has risen in the secondary vessel so that the water comes in contact with the float a the float will be raised and the arm (7 will contact with the trip-rod and raise it to a vertical or neutral position after which a slight upward motion of the float will tip the trip-rod 0 just beyond the vertical and then the overweight (Z will make the rod fall to the right into the position shown in Figs. 2 and 3, and this movement will cause the pin it to turn in its bearings and earry with it the U-trips m and m which will engage with the arms Z: and 7e respectively and thus make the valve pieces 7) and 0 rotate upon their respective seats so that the water valve 0 will be closed and the steam valve P will be opened as indicated in Fig. 2. The steam will. enter the, box E and pass through the pipe or nipple G into the upper part of the tank B and the pressure thereof will force the air and some steam out through the air valve l1 and will depress the water in the secondary tank and make it flow over into the primary tank A. As the water rises in the primary tank A the air that is in this tank will be forced out through the check valve l into the discharge pipe K. As long as the bucket o is submcrgedthe Weight of the float a being counterbalanced by the. counterweight c the steam valve will remain open and the water valve will remain closed, but when the surface of the water has fallen in the secondary vessel to a point such as is indicated by the line yy in Fig. l the weight of that water in the bucket above the surface of the water outside of the bucket will be sufiicient to pull the float down and make the arm 9 act upon the trip-rod a so as to move it toward the left just past the vertical position, and then the overweight 03 will cause the trip rod to fall toward the left to the position shown in Fig. 1 and thus open the water valve 0 and close the steam valve P through the medium of the U-trips m and m acting upon the arms Z1: and 713 respectively. If during the process of forcing the water from the secondary vessel into the primary vessel there is more water forced into the primary vessel than is required to fill it this eXcess of water will be discharged through the check valve N into the discharge pipe K. And if no water be supplied to the pipe I to the device it may still work although somewhat slowly, for in this case the steam in the secondary vessel will be condensed only because of the radiation from the parts there of. But this condensation will be sufficient in some cases to cause the water to be drawn from the primary vessel into the secondary and rise therein to a level sufficient to operate the valve -mechanism. It is, however, preferable to have water supplied to the device through the pipe I, as then the operation is more rapid and certain.
