DANIEL GOFF, OF MILLVILLE, NEW JERSEY, ASSIGNOR TO GOFF GRAVITY BOILER FEED COMPANY, A CORPORATION OF NEW JERSEY.

BOILER-FEED.

To all whom it may concern:

Be it known that I, DANIEL Gorr, a citizen of the United States, residing at Millville, county of Camden, State of New Jersey, have invented a new and useful Boiler- Feed, of which the following is a specification. I

My invention relates to a boiler feed, and consists of means for supplying water to boilers and utilizing the steam from the boilers to force the water thereinto.

It further consists of a novel controller which is adapted to be suitably actuated to allow the water to enter tanks or reservoirs and to supply steam from the boilers into said tanks to force the water therefrom into the boiler.

It further consists in providing valves, which are suitably actuated in order to permit the entrance of steam into the tanks for forcing the water therefrom and after the water has been forced therefrom, to permit exhaust of the steam from the tanks.

It further consists in providing a condenser for the exhaust steam.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

of a portion of one of the tanks employed with a portion of the same broken away. Fig. 1 1-. represents an elevation, showing the two valves on one of the tanks. Fig. 15 represents a plan view of one of the tanks employed.

I have found in practice that it is essential to have water properly fed to boilers and in the drawings I have shown a construction of a boiler feed which I have found operates successfully in practice and as showing an embodiment of my invention, but I desire it understood that changes may be made in the construction, the arrangement of the parts may be varied and other instrumentalities may be employed, which will come within the scope of my invention, and I do not therefore desire to be limited in every instance to the exact form as heretofore shown and described, but desire to make such changes as may be necessary.

As previously stated, I desire to supply water to a plurality of tanks or reservoirs, the supply of water being controlled by valves in each tank, so that supply of water will be cut off at the proper time. I also desire to employ the steam from the boiler to force the ater from these tanks into the boilers and I have provided on each of the tanks valves which are suitably actuated by a controller, in order that the steam will be directed or conducted into the tanks, at the proper time, to force the water therefrom and will then be cut off and exhausted from the tanks.

I have provided controller which is supplied with water from the same source as the tanks, the supply of water being properly controlled and I also conduct the steam from the boilers to the controller in order to force the water from the controller suitably directing the steam to actuate the valves of the tanks to permit the steam to enter the said tanks.

In the construction shown in Fig. 1, I have shown four boilers and four tanks, it being understood that the two tanks on one side, that is the right of the figure, are arranged to be supplied with water, while the two tanks on the left of the figure are being supplied with steam to force the water therefrom, although this may not be necessary in every instance and I may employ a single tank or any number, as may be desired.

1 designates a plurality of boilers in the present instance, although one or any other number may be employed and I desire to utilize the steam' from the boilers to force water from a suitable supply into the boilers.

2 designates a supply pipe leading from any suitable source through which water is fed in a suitable condenser or heater 3.

4 designates a pipe leading from the condenser through which the water passes from the condenser, said pipe 4 having a branch leading therefrom, a branch 6 leading therefrom, a branch 7 leading therefrom and a branch 8 leading therefrom, said branches each communicating with a tank or receptacle 9 whereby it will be understood hat water will pass through pipe 4 and through the various branches into the said tanks at the proper time. Leading from each of the tanks is a pipe 10 which communicates with the pipe 11 suitably connected by branches 12 with each of the boilers. Also communicating with the pipe 4 is a. branch or water inlet pipe 13 which carries the water to a suitable controller 14 as will be hereinafter described, it being understood, however, that a pipe 15 is in suitable connection with said controller and is adapted to conductwater therefrom back to the pipe 11 and thence into the boi ers at the proper time. In order to conduct the steam fro-1n the boilers, to force the water from the tanks 9 and controller 14 I provide a branch 16 leading from each of the boilers which branches communicate with a pipe 17, from which leads a pipe 18, which, by means of a pipe 19 communicates with the controller 14 as will be hereinafter described, and which pipe 19 is provided with a branch 20 leading therefrom and connecting with a pipe 21, from which leads branches 22 each of which communicate with the interior of a tank 9, which branches 22 are properly controlled by valve mechanism as will be hereinafter described whereby it will be un derstood that as steam passes through the branches 16 into pipe 17 it will be directed into the pipe 18 and through pipe 19 into the controller and will also pass through the branch 20 into the pipe 21 from thence it will pass through the branches or pipes 22 to properly enter the tanks 9, it being understood that the controller provides for the proper admission of the steam into the tanks 9, in order to force the water therefrom through the branches 10, pipe 11 and branches 12 into the boilers.

The water from the condenser 3 is directed through the pipe 4 and into the pipe 13 which is provided with a suitable check valve 23, see Fig. 6, so positioned as to allow the passage of the water therethrough in the direction indicated by the arrow in Fig. 6 and the water will pass through the pipe which is in suitable connection with the pipe 13 and will be directed into a tank 24 which forms part of the controller and which pivotally mounted to oscillate, as will be hereinafter described, it being noted that the said pipe 25, in the present instance communicates with the interior of the tank 24 through the trunnion 26, see Fig. 12, on one side of the tank 24. The pipe 13 is also provided with a valve 27 which is in suitable connection with the tank 24 in order to be opened and closed by the rocking thereof, as will be hereinafter described, and said valve 27 is open when the tank 24 is in its elevated position, as seen in Figs. 3 and 4, 8 and 9. After a sutlicient quantity of water has been received in the tank 24 the weight of the water therein will overcome the weights 45 which are suitably connected with said tank 24 at which time the lever will turn with its trunnions 26 and 49 that are in suitable communication therewith in the direction indicated by the arrow (6 in Fig. 8. At the same time the valve 27 which is in suitable communication with the tank 24 by means of the lever 82 and link 83 will be closed and thus cuts off a further supply of water to the tank 24. Suitably connected with the tank 24 is an arm 30 which in the present instance serves to support the weights 45 and connected with the arm 30 is a link 28 to which is suitably connected a link 29 the lower end of which is pivotally connected to the cylinder 31 upon one side of its pivot 32*, whereby it will be understood that as the tank 24 lowers, the end of the cylinder 31, with which the link 29 is connected, will be elevated by reason of the elevation of the arm 30 and the opposite end of the cylinder 31 will be lowered in the direction indicated by the arrow 6 in Fig. 8.

32 designates a weight or ball freely movable in the said cylinder 31 and as the cylin der 31 is rocked by the movement of the tank 24, the ball will be caused to move from its position seen in Fig. 8 to that seen in Fig. 10 and thus insure the proper rocking movement of the tank 24. Connected with the cylinder 31 upon the opposite side of its pivotal point 32 is a link 33 which is connected with a lever 34 on one side of its fulcrum the opposite end of said lever 34 having a link 36 connected therewith which is connected with the lever 37, which is pivoted at 46 to a suitable stationary point, while connected to said lever 37 is a valve 38 which controls or is suitably situated in the pipe 19, in order to control the passage of steam from said pipe into the controller and as the position of the cylinder 31 is changed from that seen in Fig. 8, it will be understood that through the medium of the link 33, lever 34, link 36 and lever 37 the valve 38 will be opened and steam from the boilers 1 flowing through pipes 16, 1S and 19 is directed through the valve 38 into the pipe 39 and then through the trunnion 49 and whereby it will be understood that suitable steam pressure is exerted on the water within the tank 24; and casing 40 to force.

water therefrom. As the tank 2st and its adjuncts are located above the boilers, it will be understood in addition to pressure of the steam within the tank and easing, the force of gravity or weight of the water flowing from the tank and easing, overcomes the pressure in the boilers 1 and opens the valve 13, see Fig. 5, which is situated in the pipe 15, which leads from the pipe 25 and communicates with the pipe 11 which is in communication with the branches 12, so that the water will pass through these pipes into the boilers against the back pressure of steam from said boilers, it being understood that the valve 43 in the pipe 15 is closed under normal conditions by steam pressure from the boilers 81 which is exerted in the direction indicated by the arrow 0 in Fig. 6. It will be noted that the branches 12 are each provided with a checkvalve 14: to prevent backward flow of water from said boilers 1 but which permit passage of water into the boilers. When the valve 13 is opened the pressure of the water from the tank 24 and cas ing 40 will serve to hold the valve 23 in the pipe 13 closed so that water cannot pass in that direction but must flow to the boilers. From the above it will be understood that I have directed water from the condenser 3 into the tank 24: in order to lower the same and have conducted steam from the boiler into said tank 241 to force the water therefrom into the boiler 1, it being of course understood that water in the meantime has been fed into the two tanks 9 at the right, as seen in Fig. 1 and I now desire to introduce steam from the boilers into these two tanks 5) in order to exert a pressure therein to force the water therefrom. hen the valve 38 is opened as hereinbefore described, in addi tion to directing the steam from the boilers 1 into the casing 40 and tank 24 it will be understood that some of the steam is directed through pipe 47, which is in communication with the pipe 39 into the branch pipes 418, each of which discharges into a suitable cylinder 50, carried by the tan s 9 in any suitable manner, as will be best understood from Fi s. 1 and 13, and will operate the piston 89 in each of said cylinders to elevate the same. The pist on S9 is con nected with the weighted lever 90 pivoted at 91 to a suitable stationary point, the other side of said lever being connected with a le ver 93 which is in suitable communication with a valve 63 which controls the pipe 22 which it will be understood is in communication with the boilers 1 and is conducting steam therefrom. When the piston 89 is elevated the valve 63 is opened and steam is permitted to enter the two tanks 9 to the right as seen in F 1 and forces the water therefrom through pipes 10 into the pipe 11 and through branches 12 into the boilers 1. Get designates a second valve adjacent the first valve 63 which is in suitable connection with a lever 92, pivotally supported at 9 1 and which is in suitable connection with the weighted lever 90 in such a manner that the said valve 64: is closed when the valve 63 is opened and vice versa.

lVhen the tank 2 1- and casing 40 are emptied of water, as previously described, the weights 15 will act to raise the tank 2 1 and by reason of this the

links

28 and 29 are lowered and also the end of the cylinder 31 in the position seen in Fig. 8 which thus through the medium 01'' the links 33, lever 34, link 36 and lever 37 actuates the valve 38 to close the same thus cutting off the supply of steam which is exerted beneath the piston 89, and the weighted end of the lever 90 always will fall, closing the valve 63, on the two tanks to the right in Fig. 1 and opening the valves 64, immediately upon which the steam in the two tanks can exhaust from the pipe 62 in communication with the valve 6 1 and will be directed into the pipe 57 which is in communication with. the coil 58 in the condenser 3 and will pass through pipe 59 and be directed into the interior ot' the condenser 3, as will be understood from Fig. 2, it being noted that the pipe 59 is provided with the check valve 60 to prevent water in the condenser from entering the coil pipes 53, while the pet cock (31 is provided, which, when opened, will permit the condensed steam in the coil to escape therefrom. Also connected with the cylinder 31 is a link 67 which is connected with a lever 68 pivoted at 69, which is in suitable connection with a link 70 connected with one end of the lever 71 pivoted at 72, said lever being in suitable communication with a valve 55, suitably positioned with respect to the valve 38 and connected in such a i'i'ianner by reason of the pivotal point of the lever 71, that when the cylinder 31 is rocked when one valve is opened the other is closed, whereby it will be understood that as the tank 24 is elevated after having been emptied of water the cylinder 31 is rocked in order to open the valve and the steam from the interior of the tank 24 and easing 4-0 will exhaust through the pipe 39 and valve into the pipe which is controlled by said valve and will be directed into the pipe 57 and thus into the coil 58 as previously described with respect to the exhaust from the two tanks 9, while the steam from the pipes 457 and 4S and the cylinders will likewise exhaust as the pipe 17 is in communieation with the pipe 39. Connected with the lever 71 at 73 is a bar or rod 71, which connected with a two-way valve 75 which controls the pipe 51 which is in communication with the branch pipe leading from the pipe 21, said pipe having branches therefrom, each communicating with a cylinder similar to the cylinders 50, said cylinders 53 being respectively mounted on the tanks 9 at the left of Fig. l and said cylinders each having a piston 89 similar to that already described, the rest of the operating parts being the same as that described with respect to the two tanks at the right of Fig. 1 and it is deemed unnecessary to describe these tanks and operating parts, it being understood that as the lever 71 is operated to open the valve it will at the same time operate the valve 75 to open'the pipe 51 to the pipe 54:, whereupon as steam passes through the pipe 51 and branches 52 to the cylinders of the two tanks to the left in Fig. 1, so that the pistons 89 thereof are properly actuated to open the valves 63 on said tanks and steam from the pipes or branches 22 will pass into these tanks and force the water therefrom through pipes 10 into the pipes 11 and through the branches 12 into the boilers 1 whereby it will be understood that these tanks will be emptied. It will be understood that as soon as the tank 2% is rocked again the lever 71 is 0perated to close the valve 75 so that the steam from the cylinders 53 and pipes 01 and can exhaust, at which time the valves 63 are closed and the valves 64: opened, on the tanks on the left hand of Fig. 1 so that the steam therefrom can exhaust through the pipes (32 and into the coil 58 to the condenser 3. I11 the meantime, water has been permitted to flow into the tanks 9 at the right of Fig. 1, the amount of water in each of the tanks being controlled by a float 66, each of the tanks 9 being supplied with a float and each of which is in suitable communication with a. valve 65, each of the branches 5, 6, 7 and 8, through which water is conducted, being provided with a valve, so that when the float (S6 is elevated to the proper level in a tank 9 the further supply of water is cut off. Immediately that the tank 24 is elevated the valve 27 opened again and water is again permitted to flow into the tank 2% as previously described and lower the same again, the operation of the parts being similar to that already set forth as above. In order to prevent the steam in the tanks 9 from forcing water back through the various branches in the condenser 3, I have provided the branch 8 and check valve 98 in branch 0 and check valve 101 and in the branch 5, check valve 100 which will serve to prevent improper movement of the water. I also provide suitable check valves 96 in the branches 10 to prevent the water from coming from the boilers back into the tanks ter which is fed to the boilers with suitable" boiler compound and I have shown in Fig. at a tank 77 which is adapted to receive the compound. Leading from the steam supply pipe 39 is a pipe 76 which conducts steam from said pipe 39 and discharges the same into the upper portion of the tank 77, a suitable valve 79 being situated in pipe to prevent steam from backing up.

78 designates a pipe leading from the tank 77 and communicating with pipe 15 so that the boiler compound will be discharged into the water as it passes through pipe 15 and is directed into the boilers. In said pipe 78 I provide a valve 81 which can be suitably regulated to supply the requisite amount of boiler compound to the water and I also provide a valve 80 which will prevent water from backing up and being forced into the tank 77 as will be evident. I desire it understood that the parts may be supported in any desired or suitable manner and in the drawings I have shown rollers 102 which support the trunnions 26 and 49 of the tank 24 and its adjuncts, said rollers in the present instance being supported on the frame 103, which supports the controller.

T ie operation is as follows :Assuming the several parts of this device to be in the positions indicated in the drawings, water from asuitable source of supply flows through the pipe 2 and passing through the cock 97 enters the condenser or heater 3 and passes therefrom through the pipe a and is directed thereby to the branch pipe 8 and passing through the check valve 98 enters the tank 9 at the righthand end of the series of tanks 9 seen in Fig. 1, until the float 66 in said tank is raised to close the valve 65. The water in the pipe s also enters the branch pipe 7 and passing through the check valve 99 enters the tank 9, that is, in communication with the branch 7 until the proper height of water is reached. The water in the pipe 4 also enters the branch pipe 13 and passing through the check valve enters the tank 2e and the water from the pipe 4 also enters the branches 5 and (3 and passing through their respective check valves 100 and 101 enters the tanks 9 to the proper height.

IVhen the weight of the water within the tank 24, as fed thereto from the condenser 3, exceeds that of the weights 45 and the ball 32 said tank turns on its trunnions 26 and L9 and in the direction indicated by the arrow a in Fig. 8.

The tank 24 in moving in the direction i11- dicated by the arrow a depresses the arm 82 and link 83, thus closing the valve 27 and shutting off the supply of water from the condenser 3 to the tank 24:.

The downward movei'nentof the tank 24 elevates the arm 80,

links

28 and 29, cans ing the cylinder 81 to move in the direction indicated by arrow Z) in Fig. 8, which open the valve 38 and closes the alve Steam from the boilers passes through the branches 16, pipe 1'? and pipe 18, to the pipe and 21 and through the branches is stopped by the valves (33 until opened. as hereinafter described. Steam is also in the pipe 19 and when the valve 38 is opened as described, the steam passes thence to the pipes 39, 4-1. and 4:2 and discharges into the tank 24, and casing so as to exert a downward pressure on the water within said tank causing it to tlow therefrom through check valve 43 and pipes 15, 1.1 and 12'and check valves 1-4: and dipcharge into the boilers 1. it is to be u1'iderstood that the water as forced through the

pipes

11 and 10 by the controller 1 cannot enter the tanks 9 on account of the check valves 96. Steam from the boilers 1 passing through the open valve 38 also tlows through the pipes 39, 47 and l8 and enters the cylinders 50 thus elevating the piston 89 therein so as to turn the lever 90 on its fulcrum 91 as will be understood from Figs. 1 and 13.

The turning of the lever 90, due to the upward movement of the piston 89. operates the levers J2 and 93 so as to open the valves 63 and close the valves l-t that cooperate with the tanks 5) that are supplied with 'ater through the branch pipes 7 and 8. that is the two tanks 9 to the right in Fig. 1.

Steam from the boilers 1 after passing through the

pipes

16, 18, 20, 21 and 2:2 reaches the valves (33 and since said valves 3 that cooperate with the tanks 9 are supplied with water by the pipes T and S are open, as hereinbetore described, live steam passes through the same and enters their respective tanks 9 so as to exert a dmvnward pressure on the water within said tanks and force the water theretron'i through the valves 96 and pipes 10 to the pipes 11 and 12 and finally through the check valves 44 into the boilers 1.

It is to be understood that steam in branches 22 cannot pass through the valves 63 that cooperate with the tanks 9 as supplied with water through the branches 5 and 6, that is the two tanks to the left in Fig. 1. on account of their being closed when the tank 24L- is in its lowered position.

When the water has been discharged from the tank 2 1 the weights return said tank to its elevated position as seen in Fig. 8, it being understood that in doing this said tank 2 1 turns with its trunnions 26 and 49 on the rollers 102 and in a direction opposite to that indicated by the arrow a. The upward movement of the tank 24; closes the valve 38 and shuts otl the supply of steam to said tank 2% and also to the cylinders 50 that cooperate with the tanks 9 fed with water through the branches 7 and 8.

As soon as the pressure is released in the cylinders 50 the pistons 89 fall or lower carrying with them the end of the lever 90 which actuates the lever 98 to close the valve 63 so that no further steam is permitted to enter the tanks 9 to the right of Fig. 1 and the valve Get, however is opened permitting the exhaust of the steam from these tanks 9 through pipes 62 back into the condenser. In the meantime, the water having been forced from said tanks 9 the float valves 66 therein are lowered in order to open the valves and the ater will again be directed in these tanks to the proper height.

\Vhen the tank has reached its elevated or normal position seen in Fig. 7, it opens the *alve by reason of the lowering of the arm 30 that cooperates with the link 28. link 29, cylinder 31, link (37, lever (38, link and lever '71, connected with said valve as will be understood from Fig". at.

As soon as the valve 55 is opened the steam within the tank 24- escapes therefrom through the pipes 42, 41, and valve and passing through the

pipes

56 and 57 enters the coil 58 as exhaust steam and discharges through the pipe 59 into the condenser 3.

hen the tank 24: is in. its elevated position, in addition to opening the valve 55 it also opens the valve '75 which as hereinbetore described is a. two-way valve. The opening of the valve '75 accomplished through the lever 71 and rod 74, as will be understood from Fig. 7

hen the valve 75 is open the steam from the pipe 21 passes through the pipe 54 to the pipe 51 and to the cvlinders and thus on the underside of the piston 89, which elevates the pistons therein and so opens the valves 63 and the steam from the pipes 22 passes into the tanks 9 at the left in Fig. 1 and forces the water into the boilers 1. When the tank 24 lowers again. the valve 75 is actuated to close the communication with the pipe 54- and open the pipe 51 to exhaust to the atmosphere. This causes the piston 89 to lower and in so doing operates the levers 90. 92 and 93 so as to close the valves 63 and open the valves 64: that cooperate with the tanks 9 as supplied with ater by the branch pipes 7 and 8. lVhen said valves 63 are closed the supply of steam to their receptive tanks 9 is shut ofii while at the same time the opening of the valves 64: permits the steam within said tanks to escape therethrough and flowing through the

pipes

62 and 57 enters the coil of pipe 58 in the condenser 3.

It is apparent from the foregoing description that when the two tanks 9 on the right of the controller 1 1 in Fig. l are filling with water, the two tanks 9 on the left of said controller let are discharging water into the boilers l and vice versa.

The controller ltk is provided with a registering device 105 of any well known description, seen in Figs. 5 and 11, that is adapted to indicate the number of oscillations of the tank 24 in a given time, it being observed that said registering device is operated by the lever 71.
