FORCE-PUMP.

SPECIFIATION forming partof Letters Patent No. 372,888, dated November 8, 1887.

, Application niet october 4, 188s. serial No. 215,265. (No modem' To aZZ whom it may concern:

Beit known that I, Rosoon BEAN, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Force-Pumps, of which the following is a specification, reference being had therein to the accompanying'drawings. y'

This invention relates to improvements in force-pumps; and the invention consists, first, in closing the upper end of that part of the barrel which constitutes the cylinder proper by means of a removable head or cap, in a j plunger whichacts below the head, and in con r 5k structing the cylinder with a dischargeopening between the head and the plunger, whereby the water is resisted when drawn up by the plunger, so as to form a force-pump without the use of an inner cylinder and another plunger, or of the usual' enlarged piston, both lwhich serve to form a partial vacuum or water-space at the downward movement of the handle and to displace the water on the reverse movement thereof; and whereby, also, the water is given a place of exit other than through the head.

The invention consists, secondly, in combining the removable head with an attachment, either a rod or tube, which extends to within reach'from the platform and is secured so as to suspend the head and support it.

The invention also consists, thirdly, of a barrel or upper extension of the cylinder proper of suflicient diameter'to permit of the withdrawal of the head and plunger, &c., through itwhen combined with a stock supported by the platform and constructed to receive and strongly hold or bind the barrel.

Y In the accompanying drawings, forming a part of this specification, and on which like reference-letters indicate corresponding features, Figure l represents an elevation of my improved pump, showing the lower portion thereof in section; Fig. 2, a detached plan view of the stock-cover; Fig. 3, a transverse 'sectional View on the line a: of Fig. 4; Fig. 4, a

Vvertical sectional view of the upper end of the barrel and the cover, showing also one section of the stock; Fig. 5, aside elevation of the same parts, and likewise illustrating one section of the stock; and Fig. 6, a transverse sectional view of the two-part stock, showing the line of division between said parts, the view being taken on the line y y of Fig. 4.-

The letter A designates a platform or curb at the mouth of the well, and the letter B a metallic stock of cylindrical form, and preferably constructed in two vertical parts held together by the lugs and bolts C, and fashioned at its lower end to' set firmly upon the platform. Each part has a vertical standard, D, (one only appearing) and both constituting the fulcrurnsupport for the handle. The barrel D is fitted to the cylindrical interior of the stock, and when the two parts are drawn tightly together by the bolts they clamp and strongly secure the barrel. This pump is contemplated to form a deep-Well pump, as well as one for shallow wells, and in case the frictional contact in the former instances should not prove sufficient to sustain the weight, I provide the barrel with a band, E, adapted to be shrunk thereon, and having lugs F, which enter recesses in the parts of the stock, as seen in Figs. 4 and 5.

The letter G indicates the cover, which fits upon the stock and is held in any convenient manner, and has a flange entering and fitting Vthe barrel, as seen in Figs. 3 and 4. This cover has a screwthreaded recess in the under side, and in this recess is screwed the upper end of the attachment H, which supports the removable head I. This attachment may of course be secured in some other way; but it is desirablethat 'it should be Within reach of a person standing on the platform,whereby itrmay be Withdrawn, together with the removable head I, to permit of the withdrawal of the piston and plunger. The attachment is either a rod or a tube, and when the latter it serves also as an airchamber. From a point in proximity with the position of the removable head I downward the barrel becomes a cylinder in function, and by the term cylinder as hereinafter used, such will be the meaning. The removable head is preferably provided With a packing at its periphery, and is made to snugly lit the cylinder, to practically prevent the upward dow of the water as it is lifted or forced by the plunger.

This is the essential function of the head,while incidentally it prevents any gravel or other foreign matter which may fall into the barrel from finding its way to the cylinder. The cyl- 5 inder proper is preferably constructed in sections J K, or more, for the purpose of lengthening it to suit wells more or less deep, and so as to convert a shallow-well pump into a deep-well pump. These sections are held toro gether by means of screw-threaded sleeves L. The letter M indicates the piston-rod,which may be either tubular or solid. When the former, it is sufficient if the hollow portion begins at about the point N,where an opening i5 is formed, and extends thence upward any desired distance. Thus an air-chamber is formed which may be used in conjunction with or separately from the air-chamber, constituted, in some instances, by the attachment H. A hole having a seat is formed in the head I, and a thimble, O, is applied, whereby a passage and a stuffing-box are afforded for the piston-rod. The cylinder, at a convenient point below the head and above the plunger, is provided with a discharge, P, to which connects a discharge-pipe, O', passing up through the platform and terminating in a spout. The lower end of the cylinder has a valve of any approved construction.

The attachment may be held by other means than the cover, and I do not desire to be understood as limiting myself to the means shown alone. The piston-rod is constructed also in sections--as seen, for example, at Q-whereby it may be lengthencd to agree with the cylinder.

It should be noted that the essential function of the head I is to stop the upward escape of the water and to coact with t-he plunger in securing a force-pump devoid of the inner cylinder or enlarged piston, as already hereinbefore explained. Furthermore, the presence of the discharge passage between the head and the plunger is deemed of peculiar virtue in contributing to this end. The removability of the head permits of its being withdrawn, and of the operating mechanism of the pump being also withdrawn from theplatform above and without disturbing the struct- 5c ure generally. It is preferred to support the cylinder by means of a barrel, but it is obvious that it may be supported by rods or otherwise. It should be also observed that the position of the head I is below the freezing-point, so that there is never any accumulation of water as high as the freezing point. The small quantity which may remain in the pipe O' after using the pump runs back into the cylinder below the head. This is of importance in keeping the pump free from ice.

I would here observe and have it understood that the idea of a removable head used in connection with a puiiip-cylinder is not now distinctively new, as the same may be seen in Letters Patent of the United States issued to me January 26, 1886, and numbered 334,732, for improvements in pumps. I would also have it understood that I am aware that pumpcylinders with lateral water-discharge openings are not distinctively novel.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a pump, the combination, with the cylinder constructed to be supported from the platform above it and having a lateral discharge .below the platform and the freezingpoint, and a discharge-pipe leading from said discharge to and above the platform, of a removable head,which cuts off the upward rise of the Water located within the cylinder and. below the freezing-point, and above the said discharge, an attachment connected to the head and extending to a point within reach from the platform,and a piston-rod working through the head,and having a plunger within the cylinder and below the head.

2. In a pump, the combination, with a cylinder supported from the platform above 1t and provided with a lateral discharge located below the platform and the freezing-point and having a pipe which leads to and above the platform, of a removable head, which vcuts off the upward rise of the water located in the cylinder below the freezing-point, and above the lateral discharge, a tubular attachment secured to the head at its lower end and extending within reach of the platform and there secured and closed to form an air-chamber, and a piston-rod having a plunger within the cylinder and below the said discharge.

3. In a pump, the combination, with a cylinder and its support connected to it and extended to and above the platform and there secured, of a removable head located below the freezing-point and constructed to cut off the upward rise of the water, and having a support which extends above and is secured within reach of the platform, whereby the head is held and maybe withdrawn, a pistonrod Working through the head, and having a plunger below the head and a discharge for the water.

4. In a pump, the combination, with a barrel extended above and below the platform and supported by the saine, of a removable head located below the freezing-point and within the cylinder, and a support for said head connected to it and extended above it and secured within reach of the platform.

5. In a pump, the combination, with a divided cylindrical stock and a barrel tted within the stock and clamped and held by it, of a cylinder secured to the lower end of the barrel, a removable head, which cuts off the upward rise of the water and islocated below the platform and forms a division between the cylinder andthe barrel, and an attachment secured to the removable head at its lower end and at its upper end within reach of the platform,

whereby the headmay be withdrawn and the operating mechanism also lifted out through the barrel. v

6. In a pump, the combination, with a ver- 5 tically-divided stock having a cylindrical interior and a barrel having an exterior correspending in shape with the interior of the stock and fitted within and clamped and held by the stock, of acylinder secured to the lower 1c end of the barrel, the barrel being as large interiorly as the interior of A the cylinder, whereby the operating mechanism may be Withdrawn.

In testimony whereof I afx my signature in presence of two witnesses.
