SPECIFICATION forming part Of Letters Patent N0. 595,631, dated December 14, 1897. Application filed May 18, 1897. Serial No. 637,056. (No model.)

To @ZZ whom it may concern:

Be it known thatDANIEL J oB,deceased, late of Warren, in the county of Trumbull and State of Ohio,havinginvented certain newand useful Improvements in Engines orPumps, I, LEWIS S. JOB, administrator of the estate of the said DANIEL JOB, do hereby declare the following to beafull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention contemplates certain new` and useful improvements in pumps or engines.

The primary object of the invention is to simplify the construction of the valve-casing and the arrangement of the valves and ports, so that a continuous outflow may be maintained. This is accomplished by providing a cylinder into which open near each end ports leading from the valve-chamber, which forms the inlet, said valve-chamber being in communication at its end with a dischargechamber. The ports of the valve-chamber are alternately opened and closed. Through each of them the water or other fluid is made to travel in opposite directions, alternating at each end of the cylinder, whereby a continuous outliow is obtained. The improvements are alike applicable to steam-valves. Ordinarily two corresponding casings are connected together and the piston or followers and Valves are operated in unison, steam being admitted. to one casing for effecting the operation of the water-valves, or when steam is applied to the latter the other set of valves, dac., may be employed for producing an airblast.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a side View, the water-valve casing being in section. Fig. 2 is a plan view, both casings being in section. Fig. 3 is a transverse sectional view on line 3 3, Fig. l. Fig. 4 is a similar but enlarged view on line 4. 4, Fig. 2.

Referring to the drawings, .A designates the steam-casing, and B the Water-casing. The construction of both casings and the arrangement of the valves, &c., therein being substantially alike a description of one will sufiice for both. Within the casing is a cylinder a, in which a piston or follower a is capable of being moved back and forth. The rod d2 of this piston is common to both pisvtons and extends through stuiiing-boxes a3 on the inner end plates a4. Within the casing, above the cylinder, are two cylindrical bores or chambers b b', an inlet-pipe b2 opening centrally into the former and an outlet-pipe b3 leading from the center to the latter. Communication between the ends of these bores or chambers b b' is had through ports b4, formed in the end plates of the casing. The boreor chamber b communicates near its ends with the cylinder o/by ports b5 b, through which the Water, steam, or other fluid is made to travel rst downward andvthence upward before passing into the bore or chamber b'.

C C designate two piston-valves mounted on a rod d and designed to slide back and forth in the bore or chamber b, alternately controlling the passages through the ports b5 o6. The rod d is extended from one casing to the other, and both sets of piston-Valves are secured thereon. As shown, however, the rod is disjointed and united byacoupling d', it sometimes being preferred to make the rod adjustable, in which eventthe valve-chamber of one casing is arranged on a line a little below the chamber of the other casing. To this valve-rod (l are adjustably attached two tappets d2 d3, which slide back and forth on a guide-bar d4, secured between the two casings. Toa stationarybracket d5, attached to base-plate d6, is fulcrumed the lower end of the lever E, which latter has two projections e c, which are designed to actuate the tappets d2 d3, respectively. A tappet e2, clamped on the piston-rod, projects into a curved slot e3 in the lever E. The tappet has a forked guide e4, which slides back and forth on the valve-rod d, preventingl the tappet from dropping. A weight e5 is adjustably secured on lever E by a screw e6.

In practice steam is admitted to the casing A to eect the operation of the piston and valves therein, which in turn operate the corresponding parts of the casing B, into which Water is drawn through pipe b2. The description of the operation of the Water-valves will IOO piston, will be caused to travel upwardv through port h6, and being arrested in one direction by valve d' will then pass through port b4 into Water-outlet chamber b'. As the piston starts on its return movement-that is, from left to right-the valve-rod d, having been previously moved so as to throw the valves d d to theleft of their respective ports 5 b5 h6, the vwater now in advance .of said piston, previously drawn down through portb?, iscaused to travel upward therethrough and pass through port b4 tothe water-outletchamber.

Vhile this is occurring the first-deff scribed operation is being 4repeated at ltheff lleft-.hand end-that is, the water is being drawn down through port Gintothecylin-l der ,in rear of the piston or follower. Thus it will be seen that water is introduced into each end of the casing througha single port, through which it has to retravel in its passage to the outlet-pipe.

Vhile certain means have been shown for operating the piston and the valves, it is vvobvious that various forms of mechanism may be employed for that purpose, it being necessary in all instances that the valves be operated in the manner described-that is to'say, simultaneously with the piston or follower changing Athe direction of its travel; nor is it absolutely lessential that the parts 4of one valve-casing be duplicated, although decidedly preferable.

In the construction shown,when the steampiston approaches the end of its ,forward stroke the tappet ezstrikes the end of the slot cand throws over the lever E, causing one of the projections e e to strilre one of the tappe/ts d2 d3 with suiiicient force to lreverse thevalves. Steam and Water are then admitted to the other end of their respective cylinders andthe pistons are moved in reverse direction. The cushioning of the steampiston is effected by the action of the lever reversing the valves just before the piston reaches the end of its stroke. The afdjustability of the weight ,on the lever enables the tappets to be operated so as to work the valves with precision.

What is `claimed is- 1. A pumpor enginecomprising a casing having parallel inletland outlet chambers, a cylinder, and two sets of ports, one set conneeting said inlet-chamber with said cylinder, and the other set connecting said inlet *and outlet chambers, a piston in said cylinder, and valves in said inlet-chamber, for opening and closing said sets of ports, substantially as set forth.

2. A pump or engine comprising a casing having upper inlet and outlet chambers arranged parallel with each other, and having, respectively, centrally-disposed inlet and outletOpeningS, a lower cylinder, ports leading from said inlet-chamber to said cylinder and from said inlet-chamber to said outlet-chamber, a piston movable in said cylinder, vand valves .in .said inlet-chamber -for alternately opening and closing said ports, substantially ,as lset forth.

The combination with the two casings,

.each having upper, parallel inlet and outlet chambers, a lower cylinder parallel with said chambers, and ports leading from said Ainletchamber :to said cylinder, and from said inlet-.chamber to said outlet-chamber, vof the pistons in said cylinder on a common rod, a tappet on said piston-rod, valves lin said inlet-chambers, av rod or rods therefor designed to move said valves in unison, tappets onsaid latter rod or rods, and a lever designed to be engaged by said tappet of said piston-rod and caused to strike said tappets of said valve ,rod or rods, substantially as set forth.

4. The combination with the two casings, each having upper, parallel inlet and outlet chambers@ lower cylinder parallel with said chambers, aud ports leading from said inletchamber to said cylinder, and from said inlet-chamber to said outlet-chamber, the pistons in said cylinder, a rod common to said pistons, and the valves provided with `rods connected together,'of the tappets secured on said rods, a guide therefor, a lever pivoted between said tappets and provided with a slot, a tappet on said piston-rod engaging with said'slot, and `a weight adjustablysecured upon the upper part of said lever, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
