Application filed Ap'ril 13, 1922. Sieral No. 552,263.

To all wlwm t may concer-n:

Be it known that I, JAMES CARVILL GOR- MAN, a citizen of the United States. residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements .in Convertible Open Spout and Plunger Force Pumps; and 1 do hereby declare the following to .be a full,

' 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 relates to pumps, and more particularly to a convertible open spout and.

closed type diaphragm' and plunger force pump.

If a contractor or builder in need of a pump first purchases a pump of the lopen type as heretofore ordinarily constructed and known as 'a lift pump, which will raise water to a height of about 25 feet., and

, finds later that the'water must be raised toy a height of'say, 50 feet, it becomes necessary for him to purchase yanother pump of thev closedftype, known as aA force pump, and the cost price of the two separate units is twice or more than twice the icostof a sin le pump. he primary object ol' my. invention is to 4provide'a simple, efficient, inexpensive and reliable pump of the openl or closed type with means for easily and quickly converting a pump of the open type into a pump of the closed type, or vice versa, and which will cost little more than one-half of the cost oftwo pumps-one of lthe openspout and the otherof the closed type-thus en abling the purchaser, for a few dollars in excess of the cost of one pump, to purchase interchangeable parts for convertingr a diaphragm pump of eithervthe open or closedv type into a. plunger force pump., orvice versa, and avoiding the trouble and expense incident to the cost of maintenance of two separate units.

A further object of the invention is to riproduce al pump of the character referred I more particularly describedwith vreference to the accompanying drawings, which. are to be taken as a part of this specification, and then pointed out in the claims at the end of the description.

v,In said drawings, Fig. lj represents a vertical longitudinal sectional viewl of a diaphragm pump of the open spout type adapted for vconversion intoa diaphragm pump ofthe closed type, oral plunger force Puml); f

F ig; 2 represents a vertical, -longitudinal sectional elevation of thepump 'structure and operating parts show-n in Fig. 1 .converted into a plungerv force-pump;

Fig. -3 is a vertical longitudinal sectional elevation of the pumpstructure andoperat- 1 ing parts shown in Fig.l l converted into a diaphragm plunger pump of the closed plunger type;

Fig. 4f is a perspective view of a diaphragm pump of'the form shown in F ig'. 3;

Fig. 5 is a plan View of the pump base and associated parts; the jack and associated parts being removed;

Fig. 6 is a'detail 'avertical sectional view I illustrating the mode of securing the legs of the jackand clamping the edges of t le diaphragm down upon the pump base; and

Fiom 7 \is a fragmentary plan view of I the diaphragm clamping ring.

Referring to said drawings, in whichfthe same reference letters are used to denote corresponding parts in different views, .the letter A denotes the' pump base or casing, which in the form shown has a centrally enlarged portion or water passage and reduced pipe-like-extensions a and a1', on opposite sides thereof, forming diametrically opposite' inlet' and outlet openings, on'e of which, asa,l has' inserted and secured therein a valve controlled closure or coupling member B, which is secured to said extension a by means of fastening bolts 61".' inserted: through apertured lugs or flanges b on said memberv B and registering apertures in lugs.

or flanges a? on the free end'of said extension a, so as to adapte said coupling member to be readily removed and replaced when desired. The inner end of said member B is formed or provided with an inclined seat for the inlet valve C, while the out/er end thereof is' exteriorly s rew-threaded for connection with a hose-pipe. The outlet opening in said base isnormally closed by av cover-plate D, having apertured lugs, or

flanges a? to receive fastening bolts Z1 by which it is secured to said pipe-like extension al, said bolts being inserted through registering apertures in radially projecting `lugs or flanges a? on the free end of said extension al. The pump base or casing A has a central circular opening in its to-p and an upstanding annular portion or flange A1 encircling said opening to permit the passage therethrough of a reciprocating plunger ojperated by driving gearing mounted over said opening as hereinafter described.- Said base is also formed or provided with a plurality j of radially projecting arms E, having offset end-portions e to which are secured the supportlng legs fof a jack F, having mounted thereon suitable bearings in .which is journaled a crank-shaft G, which is geared tova countershaft G1, which carries at one end fast' and loose pulleys over which is passed a belt connecting said pulleys with a power engine or driving means. rllhe legs of the jack are secured to the ol'set portion e of the v lugsE by means of bolts f1 inserted through registering apertures in said lugs and radially projecting lugs or flanges on the lower c endsof the legs of the jack. ln t-he pump 4shown in Fig. l tothe crank-shaft G is detachably Secured at one end a pitman rod l which has on its free end laterally projecting arms 'i to which aresecured by bolts 1 clamping rings -K and K1 between which are secured a diaphragm .L having a central openin registeringv with the openings throng said clamping rings'and also having itsouter edge clamped between the upstandingflange A1 on the pump'b-ase and a vbut preferably a ring of peculiar construction' ashereinafter described. The inner rimofth'e upper clamping ring K forms a valve Seaton which a 'pop 'et-valve. V mayrest; said seat being pre erably rounded, as shown, said valve having a stem u fitted 1n a socket in the pitman rod l so that the valve may rise and fall withincerta-in lim- =its independently of th pitman rod. vrllhe spout-casing or clamping ring, as the' case .may be, is mounted on lfthe pump baseA between the four legs of the j ack'F, or within the circle described by a line -connecting said legs, so that the 'legs of the jack stmtddle the spout-casing or yother clampingf means, land the' plunges operating mechanism -is supported by said jack and the-plunger-rod or pitman arranged directly ,inerme over the center ofl said clamping means and ythe opening in the top of the pump casing with the legs of the jack resting upon radial arms on the pump base exterior to the surfacev on which the outer edge ofthe dia.- phragm rests, so that the diaphragm may be removed without disturbing the plunger operating mechanism. As sho-wn, the radially projecting arms E onV the pump base are so formed that the holes therein for the fastening bolts of the spout-casing or other means for clamping the edge of the diaphragm are about inch lower than the holes which receive the anchor bolts for the jack, sopas to permit of the machining of that part of the pump base upon which'the jack rests without machining the spout-casing or clamping ring; the feet of the legs of the jack being also machined. The de-v scribed construction permits the plunger or diaphragm and superposed clamping means to be removed without removing or changing the position of the jack, so as to throw it out of alinementfby merely removing the four bolts which hold the spout-casing or the clamping ring in place and the two bolts by which the end of the pitman rod is fastened to the crank-shaft. vAnother advantage of this construction isthat the jack y rests on inished metal surfaces, exterior to the support `:for the spout-easing or clamping 7 ring, and if removed it can only go back into plaoe in `its original position, which is not .the case with a spout casingv or clamping -v ring resting on a compressible diaphragm.

lln F igf 2 of the drawings is shown a plunger force pump comprising the pump base, jack and plungeroperating mechanism shown in Fig. l, and a solid plunger P having a pitman-rod P1, pivotally connected at one end with the crank-shaft G, taking the place of the diaphragm and pitman rod and associated parts'of the open spoutpump shown in Fig. 1, and also having a valvecontrolled closure or coupling member R attached to the outlet'opening in the pump b ase and taking the place of the cover-plate D, Fig. 1. Said valve-controlled closure R or coupling member consists of two pipe-like .members R1 and R2, one of which, as R1, is

loo

inserted within the other and secured thereto andto the pump base extension a1 by fastening bolts inserted in registering apertures in radially projecting lugs or flanges on the two coupling'members and said extension al.

The part R1 of the coupling member R 'is formed or provided with an inclined seat fora discharge valve C1 and the free end of the part R2 is threaded for connection witha pipe coupling. The plunger P is slidably fitted within and carried by a Cylindrical member or stu'fing box S fitting snugly within the circular opening -in the top of the pumpy base and having a'laterally project-- ing portion or flange s adapted to rest upon 1,444,8z/a i y 'I the upstanding ilangeZ/1 of saidbase. Said' member S `has secured thereto a gland T, by means of fastening bolts inserted through `radially projecting apertured lugs or ears' t1 thereon and similar apertured lugs or ears s1 on saidcarrier S, for confining and compressing around said plunger suitable packing material inserted in the'space provided therefor between said plunger and the inner wall of said lplunger-carrying member so as' to provide a water tight joint. l

In Fig. 3 of the drawings is shown a dia-- phragm pump 0f the closed type taking the place of the diaphragm and associated parts of Fig. l, in connection with the pump structure shown in Fig. 2 a solid plunger U being secured to a dia hragm, the outer edge of which is clamped between the upstanding flange A1 of the pump base and a clamping ring O, while its inner'edge is clamped between the plunger and a clamping ring O1 by means 'of bolts or screws 04 inserted through holes in said clamping ring and screwed into interiorly threaded sockets in saidplunger; said bolts having nuts on their vfree ends for pressing and holding 4the clamping ring firmly down upon the diaphragm. The plunger U has secured thereto 'a pitman-rod Il which is pivotally connected at one end with the crank-shaft G. The

clamping 'ring O is preferably constructed,

in separable parts o1 and 02, of semi-cylindrical form, each part being formed with diametrically lopposite overlapping end-portions with registering apertures, one arranged aboveor below the other flush with the surface thereof, asshown in Figs. 6 and 7 of the drawings, thereby permitting the two parts of the ring to be secured together by bolts O2, F ig. 6, which serve also to secure the clamping ring O to the pump body or casing. Said bolts O2 pass through holes in the-arms E of the pump base or casing A which, as shown, v'project laterally beyondl said bolts and have offset portions e provided lwith bolt holes'near their free ends to receive the fastening bolts which pass through apertured lugs on the lower ends of the legs of the jack 'for securing'the Ijack to the pump casing, as more clearly shown in Fig. 4.

The clamping" ringconstructedin separable'parts and the pump base with radially projecting-arms having oH-set end portions 1 are secured exterior to the surface'on whichv on which the supportinglegs .of the jack `which carries the driving-shaft and pitmanrod connection with the diaphragm rest and the periphery ofthe' diaphragm or other plunger-carrying means rests, are` not claimed herein, and the right is reserved to claim the same in applicants (1o-pending applications, Serial No. 384,693 led May 27,

1920, and 1921.
