To @ZZ whom t mag/concern:

Be it known that we, ALLEN TURNER and FREDERICK E. TURNER, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improvements in Controlling Devices for iVater Supply and Discharge to and from Cylinders, of which the following is a full, clear, and exact description, reference being had to the accompanyingdrawings, forming a part hereof.

Our invention relates to improvements in controlling devices for water-supply cylinders; and it consists in the peculiar combination and arrangement of devices, as will be readily understood from the following specification, taken in connection with the drawings.

Our object is to provide a means used in connection with the hydraulic hoisting` and lowering engine in general use, whereby the elevator-cage is hoisted or lowered to a certain point, the water-supply is cut off, and said elevator-cage is held stationary.

Figure 1 is a side elevation of a hydraulic engine with our invention attached. Fig. 2 is a vertical longitudinal section of the attachment, showing the interior mechanism thereof. Fig. 3 is a View showing the connection between the auxiliary valve of our attachment to which motion is imparted by the operation of a lever in the cage through the medium of a system of cables and sheaves.

The hydraulic cylinder A is connected to the main valve-cylinder B of our attachment by the pipe C. The auxiliary cylinder D is connected to the main valve-cylinder B by means of the slotted casing E. The main piston F is connected to the auxiliary piston G through the medium of a bar or rod H, which is provided with the horizontal slot h, in which rests the cr0ss-head or block I.

The block or cross-head I has pivotally secured to its sides the forward ends ofl thelinks J, the rear ends of the same being pivotally secured to the upright rod K at j. The bar K is pivotally secured near its lower end on the cylindrical rod I in the lower portion of slotted casing E, which connects the main valve and auxiliary cylinder.

The oscillating bar K has pivotally secured to it the front end of a horizontal rod M, which 5o is supported along its length by vertical posts N, through the upper portion of which it travels.

Between the supports N are secured, by means of set-screws at the desired distances, the adjustable collars O, between which are the said supports N, and coiled round the rod M the springs P.

In operation, to automatically arrest the motion of the elevator-cage at any given eX- 6o tremes the adjustable collars O are first secured at the distances desired on the rod M. The action of the piston in the cylinder A causes the movement of the cross-head Q upon the rodlM. Each of the collars O is so located 6 5 upon the rod M that it will be struck by the cross-head Q only when the elevator-cage and thus the piston of the cylinder A are at the respective ends of their desired paths, and, as will be seen from an inspection of Figs. l and 7o 2 of the drawings, if the said parts have reached the said positions the cross-head Q will by striking the collars O force the rod M and thus the piston F back or forward, as the case may be, causing it to assume the position shown in Fig. 2, thus cutting oft the entrance of Water to the cylinder A through the pipes R and C, and the exit of the same therefrom by the pipes C and V, holding the elevator in the desired position. The slot h in 8o the rod II is of such a length as to permit the piston Fto make its full strokewithout causing the ends of the slot to strike the crosshead I, contained therein, when the latter is in its normal position, (shown in full lines in 8 5 Fig. 2,) the said cross-head only striking the ends of the slot when it is pushed either backward or forward by means of the rod K, and it will thus be seen that under normal conditions the piston F may be moved back and 9o forth, regulating the movements of the elevatorcage without in any manner interfering with the movements of the piston of the main cylinder, and vice versa, the movement of the piston of the main cylinder affecting the movements of piston F only when the car has reached one of the ends of its path.

The operation of myinvention is as follows:

The elevator being` at its lowest position and it being desired to ascend, the lover F in the elevatorar is shoved to one side, throwing the sheaves E7 to one side and operating valves F8, (which foi-1n no part of my presentinvention, and therefore need not be described here,) which permit water under pressure to flow through the pipes U to the auxiliary cylnder D, forcing the piston G thereof in the direction of the arrow ,2' in Fig. 2, which, being connected to the main-valve piston F, forces the saine forward until the water from the supply-tank,passinginto the cylin derA, forces the piston therein, which causes the elevator to ascend until again arrested by the operator, as will be readily understood. To descend, the operator throws the cage-lever in the. opposite direction, which causes the water from the duplex valves to pass through the pipe T into the auxiliary cylinder, forcing the auxiliary piston and therefore the main-valve piston in the direction of the arrow y, Fig. 2, until the main-valve piston is beyond the pipe C, allowing the water from the cylinder A to escape through the discharge-pipe Y, the elevator descending with the water, as will be readily understood.

Having thus described our invention, what we claim as new, and desire to secure by .Let-

l. The combination, with a main cylinder having a piston therein, of a valve-cylinder having a piston-valve therein, a slotted rod connected with the said piston-valve, a crosshead sliding within the slot in the said slotted rod, a pivoted bar actuated oy the piston of the inain cylinder, and a link connecting the said cross-head and the said pivoted bar, as described.

i. 'lhe combination, with a main cylinder having a piston therein, of a valve-cylinder having a piston-valve therein, a slotted rod connected with the said piston-valve, a crosshead sliding within the slot in the said slotted rod, a pivoted bar, links pivoted to the cross-head in the slotted bar and to the said pivoted bar, adjustable collars upon the said rod, and a crosshead upon the piston of the inain cylinder, moving between the said collars, as described.

3. The combination, with a main cylinder having a piston therein, of an auxiliary cylinder and a valve-cylinder, a piston in each of the said cylinders, a bar havinga slot therein connected with the said auxiliary and Valve pistons, a cross-head sliding within the slot of the said bar, a pivoted har, links pivoted tothe said cross-head and to the said pivoted bar, a rod pivoted to the said pivoted bar, ad justahle collars upon the said rod, and a cross-head upon the piston of the main cylinder, inovingbetween the said collars, as described.

In testimony whereof we affix our signatures in presence ot' two witnesses.
