To o/ZZ whom, it may concern:
Be it known that I, RODNEY H. YALE, of Beat-rice, ,Gage county, Nebraska, have invented certain new and useful Improvements in Piston-Stroke Regulators, of which the following is a specication.
My invention relates to an apparatus for changing and regulating the length of the stroke of any piston-rod, pitrnan, pump-rod, or other similar device for imparting reciprocating motion; and it consists, substantially, in severing the rod at any convenient point between the power end and the workingend of the saine, thus leaving said rodin two divided sections and then interposing between such divided sections a body of liquid contained Within an inclosed stationary or movable casing, Within which casing and body of liquid a piston on the end of one or both of said sections of the rod operates, said casing being also so constructed and so connected with the sections of the rod that by the variation,either automatically or at will, of the hydrostatic or'hydraulic pressure upon the liquid within such casing or the chambers thereof the two sections of the rod may be made to approach each other or recede from each other, to reciprocate in unison and equidistantly or with varying speed and at varying distances from each other, the effect being substantially to increase or decrease the total length of the rod, considered as a Whole, including the two sections of the rod proper and also the interposed body of liquid, and thus correspondingly to increase or decrease the length of the piston-stroke, and therefore the amount of Work done by the machine.`
While my invention is capable of a wide range of uses, I have selected, for the purpose of convenient illustration and as a specially useful and advantageous application of the device, a Windmill as the motive power, it being Well known to all operators of such motors that it is often desirable and necessary, in order to obtain the most effective and economical work, to vchange the length of the stroke in the pump, according to the varying velocity of the wind, a high wind rendering a long stroke desirable, while a short stroke is more suitable in case of a light Wind.
In the accompanying drawings, Figure l is a central vertical section through one form oi' my device on the line I Iof Fig. 2, also showing, partly in section, a wind-actuated device for opening and closing a valve forming part of the apparatus. Fig. 2 is a cross-section on the line II II, Fig. l, looking downward. Fig. 3 is a central vertical section of a moditied form of the device shown in Fig. 4. Fig. 4 is a partially-sectional elevation ot' a windmill-frame and windmill with the form of my device shown in Fig. 3 attached thereto. Fig. is a detail of a part of a telescoping androtating valve-rod shown in Figs. 3 and et. Fig. 6 is a view, looking downward at the line VI VI of Fig. 4E, of a vertically-moving horizontal collar or ring and its connections which operate said valve-rod. Fig. 7 is a detail in perspective of the connections between said valve-rod and the valve shown in Fig'. 3.
Referring Vto Fig, l, l designates the preferred form ot the hydraulic stroke-regulator,
the same consisting of a metallic casing entirely filled with liquid and securely fastened to stationary supports 2 on a Windmill-traine between two divided sections 4C 5 of a pumprod. Said casing is formed to contain two piston chambers or cylinders 6 7, in axial alineinent with each other and opening into each other end to end, and also connected by free passage-ways S 9 lO and fitted with movable pistons ll l2. Said cylinders and said pistons are of dilerent diameters, the intention in the present instance being to represent piston l1 as having double the area of piston l2 and cylinder 7 of double the length of cylinder G. Piston l2 contains a central passage- Way provided with a spring-pressed valve 13, opening outwardly into passage l0, and said piston is rigidlyV connected to the piston-rod 5, which drives the pump I4. The piston l1 is mounted on the piston-rod et, which is connected to the crank l5 of the windmill. The rods are furnished with the usual packingboxes Where they pass through the top and bottom of the casing.
The cylinders 6 7 are provided at top and bottom with inwardly-extending flanges or shoulders I6 I7 1S 19 to form seats for the pistons 1l l2 and limit their movements.
The cylinder 6 and passage 8 are also provided With a connecting-pipe 20, external to the cylinder, extending from a point in the IOO , stationary guides 31.
casing above the highest point reached by piston 11 to an intermediate chamber 21 between cylinders 6 7. Said pipe is fitted with a cock or valve 22, controlled by an eXtending lever 23, Fig. 2.
24 designates a device to be driven by the wind, consisting principally of the disks 25, which are supported by arms 26, hinged to a ring 27, which revolves in and is supported by a concave ring 28, secured to the windmillframe. Saidarms are also hinged by secondary arms 29 to the movable collar 30, which is prevented from swinging laterally by the The movable collar 30 is connected to the cock or valve 22 bya pivoted arm 41, which actuates rod 32 longitudinally, by means of a bell-crank 51, in such a manner as to reduce or close the passage through said cock or valve as the movable collar 30 is carried upward by the disks 25 when revolved by the wind at such a velocity that the centrifugal force throws them outward and upward.
Figs. 3 and 4 showa modified form of the device, in which the casing 33 contains a single cylindrical Achamber 34, filled with liquid and fitted with a single piston 35, mounted on the piston-rod 4, which passes through a stuffing-box'in the top ofthe casing and upward to the windmill-crank 15. The lower or pump section of the piston-rod 5 does not. enter the cylinder in this case, but is rigidly secured in the lower end of the casing. Piston 35 is provided with a central passage-way 36, having a spring-pressed valve 37, opening inward toward the cylinder.
The connecting-pipe 38 opens into the cylinder 34 at two points, one above and the other below the limit of movement of the valve in piston 35, and said pipe is provided with a cock or valve 39, connected by a rotating rod 40 to the device 24, heretofore described in connection with Fig. 1. In this form of the device, however, inasmuch as the casing 33 is not stationary, but moves up and down with the piston-rod 5, the valve-rod 40 is made in two sections, one of which telescopes within the other, as shown in Fig. 5. In this form a connection is provided between the ring or collar 30v and valve-rod 40, consisting of a pivoted arm 4l, universal joint 42, and lever 43, as shown in Fig. 6, whereby a rotary motion is communicated to rod 40 to open or close valve 39. In order to facilitate its upward and downward movements,casing 33 is also provided with a counterweight 44, acting in the usual manner.
In the operation of the forms of the device shown in Figs. 1 and 2v it will .be seen that the upper section 4 of the piston-rod and piston 11 in cylinder 6 are at the lowest points reached in the'stroke of the windmill-crank. Now if the wind-wheel 45 is turned its crank 15 will draw rod 4 upward and also piston 11 until the crank reaches its highest point and piston l1 reaches the limit vof its stroke at flange 16. Every part of the cylinders 6 7 and the passages 8 9 l0 being filled with liqi uid and cock 22 closed it will be seen that when piston 11 moves upward, the casing 1 being fixed in a stationary position, it forces the liquid above it in cylinder 6 to move upward, and this pressure is transmitted bythe `area ol' piston 11 it must move twice as far, Iand if piston 11 moves upward eight inches piston 12 must move upward sixteen inches or to the limit of its stroke at flange 1S. Now the two pistons 11 12 having reached their highest points, with the windmill-crank 15 at its highest point, the crank begins its downward movement and through the rod 4 forces piston 11 to move downward to the position shown in Fig. 1, meanwhile forcing the liquid below it in cylinders 6 and 7 to move and transmit power to piston 12, driving it back in the manner in which it was raised to the position shown in Fig. 1.
It will be seen in the operation just described that while the crank of the windmill and the upper section 4 of the piston-rod moved in a complete upward-and-downward stroke of eight inches the lower section 5 of the rod connected with the pump 14 moved in a complete upward-and-downward stroke of sixteen inches, and it thus appearing how this form of the regulator lengthens the stroke, executing work beyond the normal, Y the vmanner in which the stroke is decreased to the normal length of stroke of the power or below the normal will be more readily understood.
lf when the pistou 11 starts on its upward stroke the cock or valve 22 is opened sufficiently to permit seven-eighths of the liquid in cylinder 6 to pass from the space above the piston to the space below it through connecting-pipe 2O while said piston is moving to its upper limit at flange 16, it will be seen that piston 12 will only be forced to move upward one-eighth as far as it did when valve 22 was closed and that it has only moved two inches while piston 11 moved eight inches, and,conversely,if valve 22 remains open-while piston 11 is moving downward on its return stroke to its original position the surplus liquid between the two pistons passes through pipe 2O and piston 12 is only forced downward two inches to its original position, as in Fig. 1.
The office of the valve 13 in piston 12 is to provide an outlet through the piston for ther surplus liquid between the pistons in case the valve 22 should be closed after piston 12 reaches its upper limit or while it is moving downward. It will thus be understood that IOO I'Io
IZO
by partly opening or closing the cock or valve 22 the length of stroke of the lower section 5 of the piston-rod may be varied from a minimum of two inches to a maximum of sixteen inches, while the upper section 4 of the rod Ais moving regularly at an eight-inch stroke.
The valve 22 is represented in the drawings as operated by the wind-actuated device 24, as hereinbefore described; but it may be operated by any other suitable device or by hand.
In considering the operation of the modi fied form shown in Figs. 3 and 4 it will be borne in mind that the casing 33 is rigidly connected to the lower or working section 5 of the rod and moves with it. Said figures represent the piston-rod 4 and the piston 35 in the cylinder 34 as being at the lowest point reached during the motion of the windmillcrank l5. If that motion con tin nes, rod 4and piston 35 will be drawn upward until the crank reaches its highest point; butinasm uch as cylinder 34 and connecting-pipe 38 are lled with liquid and valve 39 closed the piston 35 does not move in cylinder 34, but carries the casing 33 and all connections, including piston-rod 5, along withit. The crank then begins its descent and through rod 4 presses piston 35 against the bottom of cylinder 34 and carries the casing and connections back to first position.
It will be seen that in the operation just described the crank moved the piston-rod 4 and the piston 35 in the same way and the same distance that they would have been moved were the casing 33 entirely absent and the rod made continuons throughout. If, however, when rod 4 and piston 35 start on their upward stroke the valve 39 is opened sufficiently to permit enough of the liquid above piston 35 to pass around below said piston during its upward stroke to allow it to slide upward in cylinder 34 siX-eighths of the total distance it is carried upward by the crank, it will be seen that though piston 35 and rod 4are carried up eight inches the lower section 5 of the rod is only carried upward two inches. The crank then moves downward and piston 35 is pressed against the liquid, forcing six-eighths of it back through the connecting-pipe 38, and piston 35 is carried down six inches to its original position. As in the case of the other form, a valve 37 in the piston is provided', but in this case opening inwardly to permit the liquid to pass through the piston in case valve 39 in the connectingpipe should be closed before or during the downward stroke. It will thus be seen that by partially or fully opening valve 39 the length oi stroke of piston-rod 5 may be changed or varied from a minimum of two inches to a maximum of eight inches, while piston-rod 4 is moving regularly at an eightinch stroke.
As in the preceding` case, the valve 39 may be operated by the wind device 24 or in any other preferred manner or by hand. Fig.
7 shows in detail a method of transmitting the rotary motion of the valve-rod 40 to the valve 39 by means of the rigid arn147 on rod 40, the lever 4S on the valve-stein, and a cross-rod 49, connected at each end to said arm and lever by universaljoints. The valve-rod 40 is supported in a socket 50, mounted on pipe 31S.
In the operation of either form of the device in connection with a windmill it will be observed that the closing of the valve in the connecting-pipe, so as to prevent passage of liquid from one side of the piston `to the other, lengthens the stroke of the pump-rod and that opening said valve, and thus equalizing the pressure on opposite sides of the piston to a greater or less extent, shortens the stroke. The wind-actuated device 2.4 and its connections with the valves in the ctmnecting-pipes are therefore se adjusted that a high-wind velocity closes the valve partially or wholly and a moderate velocity opens itin like manner. In the first form, as shown in Fig. l, the preferred normal adjustment is fora medium stroke the length of which may be either increased or decreased. In the second form, as in Fig. 2, the normal is for a moderatelylong stroke which by the operation of the valve may be shortened.
Any preferred liquid for lling the casings may be employed in the operation of my device, but l have found some variety of oil to be the most. advantageous.
It is obvious that the dimensions of parts stated and the adjustments indicated herein are only illustrations, and that the same may be varied indeinitely, according to circumstances and the character of the work 'to be done. it is also apparent that in the general application of the device it might be arranged to operate horizontally or in any other desired position as well as vertically.
I claim as my invention and desire to secure by Letters Patentl. in a reciprocating-rod mechanism, the combination with a rod divided into two sections of a stroke-regulator interposed between and connected with said sections, the saine consisting of an inclosed casing containing a piston-chamber into which one section of the rod ex tends, a piston mounted on said section, within the chamber, havinga valved opening, a body of liquid within said chamber, and a valve-controlled passageway for passing said liquid from that part of said chamber being subjected to pressure to that part of said chamber not being subjected to pressure, substantially as set forth.
