UNITED STATES PATENT OEEIcEo BENJAMIN O. VANDUZEN, OF WINTON PLACE, OHIO.
SPECIFICATION forming parl: of Letters Patent No. 375,027, dated December 20, 1887.
Application filed April 22, 1884. Serial No. 128,888. (No model.)
To @ZZ whom, it may concern,.-
Be it known that I, BENJAMIN G. VANDUZEN, a resident of Winton Place, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in umps, of which the following is a specificaion.
My improvements are applicable to double acting pumps, and also to single-acting ones.
The various features of my invention and the several advantages arising from their use, conjointly or otherwise,will be apparent from the following description and claims.
In the accompanying drawings,Figure 1 represents a vertical central section of a doubleacting pump illustrating my invention, the pistons and drop or puppet valve, stay-rod of the forcing-cylinder, actuating-rod, upper end of pump-stock, and actuatinglever being shown. Fig. 2 represents a side elevation of the upper portion of the pump shown in Fig. l and looking at that side of the pump which is on the left hand in Fig. l. Fig. 3 represents a side elevation and also a top or plan view of the preferred form of drop or puppet valve of the pump shown in the two preceding figures.
A indicates a pump-stock made of wood. The upper end of this stock carries the actuating-lever B,pivoted to said stock in any desirable manner. In' this stock is a dischargeoutlet, O, usually provided with a dischargespout, C. The discharge-outlet C connects with the discharge-conduit D, located within the stock A, and the conduit D runs lengthwise with the stock. The lower end of the discharge-conduit connects transversely with the pump-cylinder E by means of a transverse or horizontal passage, D', passing through the side of the stock and through the upperor discharge branch, E', of the cylinder into the piston-chamber E2. This cylinder E is provided with a lower or inlet branch, E2, through which is an inlet-passage, F,which latter also extends through the side of the stock and com` municates with the upper end or portion of the inlet-conduit F, located in the stock and running lengthwise therewith. In the stock and between theinlet-conduitFand dischargeconduit D thereof is a partition, G, and the partition entirely separatesthe conduitF from lengthwise nearly to the other end.
the conduit Dand shuts off all communication between said inlet and discharge conduits.
The pumpstock is made of a single piece of wood. This wood is bored from one end The tube thus bored is made use of for the inlet-conduit F and outlet-conduit D by introducinga plug, G, into the open end of this tube and driving this plug to a point in t-he tube between the orifice F and orifice D. This plug forms a partition between the inlet and discharge conduits and prevents their communication, 'eX- cept through the orifices F and D.
The suction-cylinder E preferably has a suction space or chamber, H, in its lower end, and above this is located a diaphragm, I, provided with a raised or sand seat, J, surrounded with sand groove or channel K. |This valveseat is preferably cast iu one piece with the cylinder E. On this raised valve-seat rests a drop or puppet valve, L, preferably of the following construction, viz: A disk or plate, M, is provided with wings or radial arms m,whose exterior ends lie in a circle having a diameter nearly equal to the interior diameter of the cylinder E, so that the ends of the arms shall Iit closely within saidcylinder and yet allow the valve to slide up and down in the said cylinder. The arms m, or their under surface at least, are preferably inclined from the disk M upward as Well as outward.
It is a desirable object to lift out the puppet-valve along with the pistons and the forcing-cylinder. Such an obj ect may be attained by means of a flexible connection, W, connected to the center portion of the bottom of the suction-piston, preferably by an eye, t, and to the center portion of the valve L, preferably by an eye, X. This fiexible connection is sufficiently slack to allow the piston P to make its regular strokes without rendering the flexible connection taut.
The preferred description of fiexible connection W is a chain, as shown.
When the pistons and forcing-cylinder Q are separated and withdrawn from cylinder E, the puppet-valve L is also withdrawn by means of said chain or connection W. Then the said pistons, forcing cylinder, and puppetvalve L are to be reinserted, the chain or connection suspends the said valve L, and by IOO holding this valve over the mouth of cylinder E the valve drops'into said mouth, the inclined vB or equivalent motor.
arms m aiding to guide the said valve'int'o said mouth. After the said valve is within said cylinder E the forcing-piston l? and then the forcing-cylinder are inserted. During the operation of the pump the puppet-valve, ale though permanently connected to the piston l?, is nevertheless, on account of the flexible nature of that connection, free to rise from and fall back on its seat, according as the pressure of water is from above said valve or below it. The under side of plate M is preferably provided with a packing of leather, n, or other suitable material. Y Y
The suction-piston l?, working in suctioncylinder E, is constructed in any suitable manner, but so that it can be readily inserted in the cylinder E withoutdisturbing the packing which said valve carries. The forcing-piston Q is also constructed in any desirable manner.
The pistons l) and Q are suitably connected to the actuating-rod S, the upper end of the latter being connected to the actuating-lever This suction-piston l? and forcing-piston Q are rigidly connected together in any suitable manner. Piston Q works in the forcing-cylinder R. This forcing-cylinder Ris connected to the suction-cylinder in any desirable manner,l whereby the forcing-cylinder may be easily dropped into or lifted out from its connection with the suction-cylinder.
A preferred mode and means of connection consists as follows: The upper end or mouth, e, of the suction-cylinder is flared or inclined upward and outward. An annular fiange or ring, b, having its peripheral surface'inclined Y in a direction parallel to the inclination or flare of the adjacent portion of the mouth e of suction cylinder E, is rigidly connected to forcing-cylinder R. The middle diameter .of this annular fiange b is'preferably about that of the interior diameter ofthe cylinder-mouth e at the middle of the height of the said mouth e. The periphery of the annular flange bis provided with annular groove b,eXtending in the flange b around the cylinder R, and this groove carries a packing, preferably round -in cross-section. Such a mode enables the forcing-cylinder to be readily inserted into or connected with the cylinder E, and also in a manner such as to make the joint between the two cylinders water-tight.
The preferred means for carrying the forcing-cylinder out of the suction-cylinder when the pistons L and R are raised, and also for pushing the forcingcylinder into the suctioncylinder when the two cylinders are to loe connected, and also for holding the forcing-cylinder to place in the suctioneylinder,are as follows: To the upper portion of forcinglcylinder R, preferably to an extension, f, of said cylinder, is connected a rod, T, by means of a pivot rod or bolt, g. The connection between the forcingcylinder R and the rod T is thus a pivotal one. The forcing-cylinder is held to place in or onthe suction-cylinder through the agency of the rod T byany suitable means, the preferred means being as follows: The upper end of the rod T is pivoted by a pivot, 7L, to the lower end of a lever, V. The latter is fulcrumed on a pivot-fulcrum, p, and has a suitable handle, as l. Pivot fulcrum p is screwed into or otherwise secured to the pump-stock. When the forcing-cylinder and pistons and puppet-valve L are to be withdrawn from the cylinder E, the handle, when located, as shown, being` moved to one side. and down,the lever Vis turned,thereby starting the forcing-cylinder R from the mouth of cylinder E. Pivot 7i is now removed, and the upper end of the aetuatingrod separated from lever B, or lever B is separated from the pump-stock, and then rods S and T, forcingcylinder, pistons, and puppet-valve are together drawn up and removed.
In replacing the parts, the puppet-valve, pistons l?, and cylinder R are let down and reinserted in cylinder E, and the actuating-rod again connscted to lever B or the lever B to the pump-stock. The rod T is again connected to lever V by reinserting pivot h, and handle Z is then raised, thereby, through the agency of the toggle-joint T It V, as the latter is straightened, forcing the forcing-cylinder to place in cylinder E. When the toggle-j oint is entirely straightened, it will, by means of the intervening rod T, hold the forcing-cylinder firmly down in place on or in cylinder E. When desired, an air-vessel may be present. A preferred form of such air-vessel to be used in the discharge-conduit of the pump is as follows: D2 indicates a tube closed at top and open at bottom. This tube is provided eXteriorly at or near ea'eh end with three or more spring or elastic parts or pieces, D, preferably located at equal distances apartaround the periphery of said tube. In the drawings four of such springs are disposedaround each end of the tube D2. The preferable form of such springs is shown,.viz: Each spring consists ofa dat piece of metal, at its upper end rigidly united to the tribe D2. The lower portion of the spring is somewhat distant `from the periphery of the air-tube. The ends of the springs when not compressed lie in a circle whose diameter is greater than the diameter of the dischargeconduit. Vhen the air tube or vessel D2 is inserted in the conduit D, the springs D, being compressed, press against the interior surface of said conduit, and by the aid of friction hold the air-tube securely in place in the conduit.
The air-tube may be inserted into the discharge conduit in any desirable manner. When the pump-stoek is made of Awood and bored, as described, the air-tube D2 is first inserted through the inlet conduit F, and thence into dischargeconduit D before plug G is inserted. Then after the air-tube is in position the plug G is driven or passed into place. When desired, when the pump-stockA is of wood, the free ends of the springs Da XOO may be made sharp to stiel; into the wood of the stock; but I prefer to make the ends somewhat curved or bent inward toward the tube, and thus present a rounded su rface against the inner surface of the stock and enable the tube to be, when necessity requires, more easily withdrawn from the stock, Whether the latter be of Wood or metal.
The operation of the aforedescribed pump does not differ essentially from that'of other double-acting force-pumps. The elevation of piston I draws up the liquid through inletconduit F,orifice F', through valve seat J, and said liquid, lifting the puppetvalve L, enters the cylinder E. As the piston l? descends, the puppetvalve closes and the liquid passes through the piston I), past the valve in said piston, and enters the cylinder E above said piston P. As the pump continues to fill with liquid, the descent of forcingpiston Q operates to force a certain quantity of liquid up through the discharge-conduit, While the elevation of piston I? discharges another quantity of liquid through said conduit. The liquid rising through the discharge-conduit is ejected from the spout or equivalent dischargeopening. Thus the liquid issues from the pump in a continual stream, this stream being kept still more even by reason of the presence and action of the air-vessel D2. The cylinder E is suitably connected to the pump-stock. In the present instance anges at the sides of the inlet branch and at the sides of the outlet branch of said cylinder are provided, and through each flange and through the pumpstock is passed a bolt, i, four bolts thus holding the cylinder E to the pumpstock. The
pumpstock and the air-vessel and the puppet valve and its seat and the fiexible connection W, or any one or more of these, may be employed in a single-acting pump or in a doubleacting pump having a forcingcylinder of different description from that herein shown.
I would here mention that while the various features of my invention are preferably employed together, one or more of them may be employed wit-hout the remainder, and one or more of said features may, so far as applicable, be employed in connection with pumps or pumping devices other than those herein particularly specified.
That I claim as new and of my invention, and desire to secure by Letters Patent, is-
l. In a pump, the combination of a suctioncylinder and a removable forcing cylinder and rod T, pivoted to the forcing-cylinder, and togglejoint T h V, substantially as and for the purposes specified. p
2. In a pump, the combination of a suctioncylinder and a removable forcing cylinder provided with extensionf, pivot g, rod T,pivot h, lever V, and pivot p, substantially as and for the purposes specified.
8. In a pump, the combination of the suction-cylinder, puppet-valve, suction piston, flexible connection between said pistou and valve, removable forcing cylinder, forcingpiston, rod T, pivoted to the forcing-cylinder, and toggle-joint, substantially as and for the purposes specified.
