PUMP.

SPECIFICATION forming part of LettersPatent No. 289,288, dated NovemberV 27, 1,883.. l A Application filed March 15,1?83. (No modell.) i

To'aZZ whom. t may concern,.-

Be itknown that I, WILLIAM S. MARsHiiLL, Aof the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Pumps, of which the following is a speciiication. f

The nature and object of my said invention will be fully disclosed by the following detailed,description.

4 Referring tothe accompanying drawings, which are made a part hereof, and on which similar letters ofV reference indicate similar parts, Figure l is a side elevation of a pump embodying my said invention; Fig. 2, a central vertical section of the same; Fig. 3, a section of the working parts similar to a portion of Fig. 2, but on an enlarged scale; Fig. 4, a horizontal sectional view, looking downwardly from the` dotted line e e; Fig. 5, a View as seen when looking downwardly from the dotted line y y; Fig. 6, a top or plan View of the removable portion of the base only, on a still further enlarged scale; Fig. 7, a central vertical section thereof on the dotted line .fc fr, the base-plate with which it engages being shown in dotted lines, Fig.r8, a top or plan view of so much of the base-plate G as shows the hole therein and the notches in its edge; and Fig. `9, a view of the clampwhich holds the air-chamber and parts immediately adjacent thereto, similar to portion of Fig.` 2, but on the scale of Figs. 6, 7, and 8.

In said drawings, the portions marked A B represent the large and small portions, respectively, of the cylinder; O, the inductionpipe; D, the. eduction or discharge pipe, which is also the valve-rod; E, the air-chamber, which also forms the support for the handle and one of the supports for the cylinder; F, a vacuum-chamber, which also forms another support for the cylinder; G, a base for the pump, which rests upon the platform; H, said platform, and I the connecting-rod by which the pump is driven. The cylinder A B is theusual two-size cylinder ordinarily used in this class of pumps. It has the lifting-valve a and the forcing-valve b, which are connected together by the rod It also has the ordinary check-valve a. There is a free passage from the inside of the cylinder part B to the coinbined valve-rod and discharge pipe D, through which the water is regularly forced by the usual and ordinary operation of the pump. The pipe Gis simply an ordinary induction-pipe. The pipe D has attached thereto at the lower end thevalve b, an d through the rod b thevalve a. tube connected to a projecting portion, a2, on the cylinder A. Ity extends up through the plate G to a suitable height to supportthe handle, and has a bracket, F', upon yits top, upon which the handle is mounted. Said bracket also forms a cap for the air-chamber, and eX- tends out and forms a guide, 1'.,'for the rod I. This air-chamber is secured to the plate G by clamps 'g g, as shown most plainly in Fig. 5. As shown in Figs. 2 and 9, one part, g, of this clamp is formed in one piece with the baseplate G, and the other, g, is loose and secured .to the first by bolts, as shown in Figs. 1 and By loosening these bolts the tube E may be moved up or down to'any desired point and there secured by tightening said bolts. This provides for any adjustment that maybe required.

The combined vacuumchamber and cylinder-support F is secured to the cylinder A in much the same manner as is the combined airchamber and support E, and to the base-plate G by being screwed into a suitable cap or boss formed thereon. It communicates with the base of the cylindenA below the checkvalve a, and is constructed perfectly air-tight. The effect is to aid in making the flow of water in the pipe C continuous during the operation of pumping. The plate G is placed upon the platform, and p racticall y forms that p art there of which immediately surrounds the pump. Inorder that the working parts may be removed for repair, &c., without disturbing the whole pump, the central portion, G', of this plate is made removable. Said portion is of sufficient size that when removed a hole will tions g* have been inserted in the notches g3, is

The air-chamber Eis a` IOO turned partly around, and thus, by the aid of said projections andtheoverlapping edges g, interlocks with the plate G in a firm and secure manner, asindicatedby the dotted lines in Fig. 5. The under side of the plate G, with which the projections y" come in contact, may be inclined, in order that there may be a wedging action as the portion G is turned, and the devices thus drawn closely together. The platform H caube any ordinary curbing or platform which is usually employed to cover a Well. The connectingrod I is mounted in bearings t" i?, and serves to connect the valve-rod either to the handle l or to a pitmau from a windmill orsimilar power. It is attached to the combined valve-rod and discharge-pipe D by a swivel-joint, d, and thus said pipe is permitted to turn in any direction without affecting the connecting-rod. The handle I is an ordinary pump-handle. lt is mounted upon a link, e', which is pivoted to the bracket E', and is connected by a pivot, fi, to the rod l.

lt Will be seen by an examination of the drawings that several of the parts of my improved pump each serve two or more purposes, which are usually only accomplished by the use of separate devices. lt can be quickly and easily put in position and as easily taken apart for purposes of readjustment or repair.

Having thus fully described my said in vention, what l claim as new, and desire to secure by Letters Patent, is-

l. The combination, in a pump, of thetwosize cylinder A B, the combined valve-rod and discharge-pipe D, the connectingrod I, and 35 means of operating the saine, said combined valve-rod and discharge-pi pe being connected to said connecting-rod by the swivel-joint d, substantially as set forth.

2. The combination of the cylinder, the combined valve-rod and discharge-pipe D, the connectingrod l, connected to said pipe D by a swivelj oint, and the handle or pitman for driving,` the same, substantially as set forth.

3. The combination ofthe cylinder, the combined valve-rod and discharge-pipe, the connecting-rod I, connected to said rod by asWivel-joint and mounted in slides to insure a vertical movement, and the handle l', connected to said rod and mounted on a link, e', said link being mounted on a pivot-bearing, substantially as set forth.

4. The combination,\vith a pump, of a base, G, having a removable portion, G', and a clamp, g, one part of which is formed in one piece with said base, and the other part is formed independently of the base, substantially as set forth.

In witness whereof l have hereunto set my hand and seal, at Indianapolis, Indiana, this 6o 12th day of March, A. D. 1883.
