METER-MOTOR.

Specification of Letters Patent.

Applicationrled May 29, 1909. Serial No. 499,124: u

To all whom it may concern:

Be it known that I; AXEL R. HOLMN, acitizen of Sweden, residing at Columbus, in the county of Franklin and State of Ohio,

rhave invented a newand useful MeterMotor, of which the following is a specification. The invention relates to a meter motor. The object of the present invention is to improve the construction of meters and mo-l tors, and to provide a simple and eflicient` machine of comparatively inexpensive construction, adapted to use fluid under pressure as a-motive power and also to enable the fluid passing through the machine to be measured.

Another object of the invention is to provide a machine of this character, equipped with meansA for converting reciprocatory motion into rotary motion.

With these andy other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out inthe claim hereto appended; it being understood that vaiiouslchanges in the form, proportion, size and minor details Vof construction, within the scope of the claim, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings Figure ,1. is a central longitudinal sectional view of a meter motor, constructed in accordance with this invention. Fig. 2 is a horizontal sectional view of the same. Fig. 3 is a vertical sectional view on theline. 3-3'of Fig. 2. Fig. 4 is a similarview on the line 4 4 of Fig. 2. Fig. 5 is a vertical sectional view on the line 5-5 of Fig. 2. Fig. 6 is a detail yview of the gear stands, illustrating the arrangement of the exterior gears. Fig. 7 is a transverse sectional view of the gear stand.

Like numerals of reference designate/corresponding parts in all the figures of the drawings.

The meter motor comprises in. its construction a cylinder 1 and a superimposed valve chest 2, provided at opposite sidesl with an inlet 3 and an outlet 4, located in- 'termediate of the ends of the valve chest 'and preferably arranged horizontally. The

inlet 3, which in practice will be connected with a suitable supply of fluid under pressure, communicates with an inlet chamber 5,

extending the entire length of the valve chest at one side thereof and provided with terminal transversely disposed extensions 6 and 7, receiving front and rear admission valves 8 and 9 for controlling the passage of water or other fluid from the inlet chamber 5 to intermediatefront and rear connecting chambers or passages 10 and 11, located in advance and in rear of a central exhaust chamber 12 and communicating with the cylinder 1 at the ends thereof through front Aand rear openings 13 and 14. The intermediate connecting chambers or passages are provided with transversely disposed branches, which are interposed between the extensions 6 and 7 of the inlet chamber and Patented July 11, 1911. 5

the exhaust chamber l`2. The said intermediate chambers or passages are also connected by upright branches 15 and 16 with the front and rear openings 13 and 14 'with the cylinder 1. A Y The front and rear admission valves 8 and 9 are adapted to alternately cover and uncover front and rear ports or openings 17 inlet chamber and formingl seats for the front and rear admission valves 8 and The longitudinal inlet chamber 5, which 1s c located at one side of the valve chest, is sep'- arated from the opposite side by a longitudinal wall or partition, having the transverse portions 19 and 20, which are connected with the ends of the valve chest by terminal longitudinal portions. The partitions 21 and 22 extend from the intermediate longitudinal portion` of the said longitudinal partition to the opposite side of the. valve chest, as clearly shown in Fig. 2 of the drawings. The partitions 21 and 22 separating the intermediate connecting chambers or passages from the central exhaustchamber 1-2 are provided with front and rear exhaust ports or openings 23 and 24, and have annular bosses surrounding the ports or openings 23' and 24 and located within the exhaust chamber 12 to form' seats for front and rear; exhaust valves 25 and 26.` The ports or open-- ings 17 and 18 and 23 and 24, which are formed in the partitions or walls of the chambers of the valve chest, are arranged in alinement, and the front and rear. admission The front and rear admission valves 8 and 9' are fixed to the valve rod by means of set screws 28, piercing hub portions of the said valves 8 and 9 and engaging the shaft, but any other suitable means may be employed for this purpose. The reciprocatory valve rod is provided with spaced threaded portions 29, receiving adjusting nuts 30, located in advance and in rear of the exhaust valves 25 and 26 and adjustably securing the same to the valve rod. When the valve rod is moved rearward to the position illustrated in Fig. 2 of the drawings, the front admission valve closes Qand covers the front admission opening or port 17, and thefront exhaust valve opens the front exhaust port or openiifg 23. Simultaneous with this operation, the rear admission valve 9 is opened and the rear exhaust valve is carried to its seat covering the rear exhaust opening or port 24. As one admission valve and one ex- 'haust valve are closed in each position of the valve rod, each will be subjected to the pressure of the motive fluid entering the valve chest, andin order to maintain the valves in their proper closed position, the admission valves 8 and 9 are constructed of greater area than the exhaust valves, so that they will .be subjected to greater pressure and will operate to hold the exhaust valves in their closed position against the pressure of the motive fluid.

The movement of the valve rod rearward and-the shifting of the valves to the position shown in Fig. 2 of the drawings causes the motive fluid to pass through the rear admission opening or port 18 into the rear intermediate connecting passage or chamber and through the same into the rear end of the cylinder 1 at the back of the piston 31, which will be moved forward, causing the water or other fluid contained in the cylinder to pass out through theV front opening 13 int the front intermediate connecting chamber or i passage and through the front exhaust opening or port 23 into the exhaust chamber 12. The fluid escapes from the exhaust chamber l2 through the outlet 4. In Fig. 1 of the drawings the valves-are shown in the reverse position, the piston being near the limit of its rearward travel, the further rearward movement of the pistonoperating through the medium of the mechanism hereinafter described to shift the valves from the 'position illustrated in Fig. l 'to that shown inKJ Fig. 2. The valve` rod extends through a stuffing box 32,211: the front end of the valve soi chest, and its rear end. operates in a hori- "Jzontal tubular guide 33h projecting rearward from the valve chest and preferably formed integral with thesame. l

1The cylinder is preferably mounted upon 165.1"a plate 34, being provided atthe bottom 'with a suit-able base having horizontal attaching flanges 35, bolted or' otherwise secured to the bed plate. The cylinder is also equipped with front and rear cylinder heads 36 and 37 the front cylinder head being pro- 70' vided with a suitable stufiing box 38 for the piston rod 39. y

The piston rod carries a rack bar 40, located at the outer end of the piston rod and forming a longitudinal extension thereof and provided with upper and,lo wer teeth 41 and laterallyv extending flanges 42. The laterally extending flanges 42 slide in grooves 43 of opposite inwardly extending guides, projecting horizontally from -the inner faces of vertical sides 44 of a gear stand. Thesides 44, which are provided at their lower ends with attaching flanges 45 are bolted to the bed plate, and they are provided with upper and lower alined bearings 46 and 47 for upper and lower horizontal shaft-s 48 and 49, carrying upper and lower inner gears 50 and 51,' which mesh with the upper and lower teeth of the rack bar 40. The upper and lower ,gears 50 and 51 are 90 arranged between the'sides of the gear case,

and they are spaced from one of the sides by integral tubular extensions 52 of the bearings thereof. The upper and lower shafts also carry exterior upper and lower gears 53 and 54, meshing' with an exterior intermediate gear 55 and located at the outer face of one of the sides of the gear stand. The upper and lower shafts are equipped with upperl and lower reversely operable clutches, -consisting of ratchet wheels y56 and 57 and pivoted spring actuated pawlsl 58 and 59. The pawls are mounted on the upper and lower inner gears 50. and

51, which are loose on the upper and lower shafts 48 and 49. The spring actuated pawls and the ratchet wheels alternately operate to rot-ate their respective shafts, and when the slidable rack bar is moved forwardly -or outwardly by the piston, the'upper gear wheel through its clutch mechanism rotates the upper shaft, and rotary motion is imparted to the intermediate outer gear 55', through the medium of the upper exterior gear wheel 53. When the direction of the piston is reversed by the means hereinafter described, and the slidable rack 'A bar is moved inwardly or rearwardly, the lower gear wheel through its awl actuatesV the lower ratchet wheel, an rotates the lower shaft and rot-ary motion is communicated `to the intermediate outer gear, through the lower gear 54, which operates to continue tle rotary motion of the intermediate gear in the same direction in which the intermediate gear is moved by the upper gear 53. The continuous reciprocatory motion of the-piston is vthus rconverted into a continuous rotary motion. The intermediate outer gear is mounted lon a central horicamco zontal shaft 60, journaled in a central bearing 61 of the adjacent side of the gear stand and in a bearing bracket 62, secured to the 4- ygear -stand at susY cppsite sides of the intermediate gear. ny suitable means may be employed for connecting the central transverse shaft 60 with the machine or mecha nism to be driven by the motor.

a Ehe valve rod is actuated to chan e the direction of the piston by means o an upwardly extending actuating arm 63, connected atits 'lower end with the iston rod 39 at the inner end of the rack ar and provided at its upper end with an opening throughwhich the valve rod passs. The, valve rod is equipped 'with front and ear springsfift and 65, located in advance and in the actuating arm tomove the valve rod forwardly and rearwardly toshift the position of the valves. The valve chest is equipped with intermediate and end air domes 68 and 69, located above the exhaust and inlet chambers, and the gear stand supports a guide 7 0 for the front or outer end of the .valve rod. j

When it is desired to use the machine as a meter, a stnoke counting device of any well known construction may be em loyed, and

,by multiplying the number an -the length of the strokes with the area of the piston in inches and dividing by the number of cubic inches 1n a gallon, the quantity of fluid in gallons that has passed through the machinepmay be ascertained.

Having thusfully described my invention,

what I claim as new anddesireto secure by Letters Patent, is

A machine of the class described comprising a cylinder, a iston operating the cyl-- inder, a valve c estprovded at one slde with an inlet opening and at the opposite side with an. outlet or exhaust opening and including a lon 'tudinal partition provided with intermeilate and terminal longitudinal portions and transverse connectmg portions, transverse partitions connecting the intermediate portion of the longitudinal partition withA the wall of the valve chest at opposite sides of the outlet or exhaust opening and forming a centrally arrangedl exhaust chamber at one-side of the valve chest, said longitudinal tion forming a continuous inlet cham r at the opposite side of the valve chestl and the transverse and terminal portions of the longitudinal partition being spaced from the transverse partitions and forming. intermediate chambers or passages and the sald partitions having alined inlet and exhaust openings, and branch passages connecting the intermediate chambers or passages with the ends of the cylinder, a valve rod extending throughA the said openings, exhaust Valves'located within the exhaust chamber and mounted on the valve rod, and admission valves fixed to the valve rod and arranged within the end portions of the en.
