WATER-PRESSURE BLOWING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 495,333, dated April 11, 1893.

Application filed May 11,1892.

To all whom it may concern:

Be it known that I, JULIUS HILLENBRAND, a subject of the Emperor of Germany, residing at Mannheim, in the Empire of Germany, have invented certain new and useful Improvements in Water-Pressure Blowing Apparatus, of which the following is a specification.

It is the object of my invention to provide an air forcing or pumping apparatus for supplying air for furnaces or any other purposes in which the motive power of water or other fluid may be utilized to keep the apparatus in constant motion so long as the pressure of the said fluid is kept up.

In the drawings, Figure 1, is a vertical sectional View of the apparatus. Fig. 2, is a plan. Fig.3, is a detail. view. Figs. 4. and 5, are detail sectional views of the valve, and Fig. 6, a sectional plan view of Fig. 3.

In the drawings are shown two tanks G G having respectively the bells orvertically movable floats G, G. The tank G" has an air inlet pipe S, which is provided with a suction valve S adapted to permit the inflow of a charge of air from the outside when the bell G, is moved vertically and arranged to prevent the escape of any air through the said inlet pipe S when the bell G falls and thus subjects the contained air charge to pressure. The tanks and bells are supplied with liquid up to the level w, r, so as to form a sealed air space X, above the said liquid level and at the top of the bells. The air pipe S, as shown extends above the liquid level and into the air space and from this air space also an air outlet pipe cl, extends which is provided with a valve 1 permitting the outflow of the air when the bell G, descends but preventing back flow when said bell rises. The air forced through the outlet pipe at under pressure from the descending bell flows into the upper air space in the bell G and thus lifts the same and this action can be made sure by increasing the weight of the forcing bell G, by weighting the same at y, dotted lines Fig. 1. The charge of air is now in the air space X of the bell G and the pressure of air from the bell G, having been cut 0% when the saidbell G has reached its highest point as will presently be described, the said bell begins to fall and force out the Serial No. 432,657. (No model.)

charge of air through the pipe d connecting with the air space X, and during this descending action of the bell G the first bell G is lifting and drawing in a fresh charge of air as will be described hereinafter. 5 5

The valve in the bell G for cutting off the pressure from the bell G, consists of a conical valve 6 on the lower end of a rod g, guided in the stationary brackets and pressed normally downward by a spring g bearing on a collar g The valve casing e, on the upper end of the air pipe d, is arranged so that the valve will close by moving upward against its seat it being pressed open or downwardly by the spring mentioned. It is closed when the 6 bell G reaches its highest point by reason of said bell striking the collar 9 thus cutting oif the pressure from the bell G, at the moment the receiving bell reaches its highest point. By this the pressure is kept steady even should the bell G, continue to move after the receiving bell reaches its highest point. Were this valve not used the pressure would be apt to vary if the bell G, continued to fall after the bell G reached its highest point.

The bell G, is raised and lowered as follows. The tank G has a pump cylinder 0, extending upward from its bottom; the piston K, of which is connected with the bell G, by the piston rod is. The piston is raised and with it the bell by a fluid as water introduced below the piston through the pipe r. The supply is controlled bya valve H,which is operated automatically from the rise and fall of the bell to let in and let out the water from the pipe r, and pump cylinder. This valve which may be of any ordinary two way variety has its stern provided with crank arms h, which are connected by the cords h, with the arms 72, which are loose on the shaft'2l' and adjacent to the tipping disk 20 also loose on the shaft 21, the said disk carrying a mercury tube a: Fig. 3, by which arrangement it is only necessary to give the tipping disk apartial movement in either direction to cause the mercury to run from one end of the tube to the other end and thus efi'ect the full movement of the disk with sufticient force to operate the valve to its opposite extreme with certainty and withaquick action. This actionisperformed I00 Gby a cord passing over the pulley f. The

valve H, is shown in Figs. 4 and 6, and as now set it will admit water to the pipe 7, from the supply pipe m, through the oppositely placed ports a leading into the axial port 0" which connects with the pipe r, as shown in Fig. 6. The action may now be followed out and may be stated as follows. The inflow of water under pressure through the pipe 4", raises the piston and bell G, to draw in a charge of air. The first portion of the upward movement of the bellis without effect on the valve controlling disk 20, as the movement of the.

wheel I), under the retracting action of its weight is lostfirst and is without efiect until the pin .2, reaches the end of the slot and tips the tipping disk and mercury tube so as tochange the position of the valve H, cut off the piper from the pipe m and place said pipe in connection with the discharge pipe r Fig. 4. The pressure on the piston K, being now relieved said piston with the bell falls and forces the air charge through the pipe d. As soon as the bell G, begins to fall it begins to turn the Wheel 19, to the left against the action of its weight and when the bell is near the limit of its down ward movement the pin 2',

comes against the opposite end of the slot and tips the disk 20, to turn the valve to let in another supply of water.

I claim as my invention 1. In combination, the two vertically movable bells G, G with their tanks, the cylinder and piston arranged to operate one of said bells, the fluid supply pipe r leading to said cylinder, the valve H, in said pipe, the means for operating the said valve including the weighted wheel I), the cord extending from the wheel I) to the bell G, the arms it loose on the shaftof the wheel, the connections from said arms to the valve stem, the tilting weighted part adapted to be moved by the wheel I) and to operate the arms 71 in the latter part of its movement, the air inlet to the bell G and the air conduit extending from the bell G tothe bell G, substantially as described.

2. In combination, the bells G, G with their tanks, the air inlet to the bell G, the air conduit between the bells, the cylinder and piston to operate the bell G, the supply pipe the valve H, therein, and the means for operating said valve including the weighted wheel b, connected by a cord with the bell G, the tipping gravity device arranged to be operated by said wheel and connections between said tipping device and .the valve stem, substantially as described.

In testimony whereof I have affixed my signature in presence of two witnesses.
