SPECIFICATION forming part of Letters Patent No. 346,720, dated August 3, 1886.
Application filed November 21, 1885. Serial No. 189,465. (No model.)
.To all whom it may concern,.-
Be it known that I, GHARLEs P. CARLSON residing atMcKeesport, in the county of Allegheny and State of Pennsylvania, a citizen of thev United States, have invented or discovered certain new and useful Improvements in Boat-Pumps, of `which improvements the following is a specification.
In the accompanying drawings, which make part of this specification, Figure 1 is a view in front elevation of my improved boat-pump, a portion of the'front wall being broken away. Fig. 2 is a view in side elevation of the same, the upper portion of the side being broken away. Fig. 3 is a horizontal sectional view, the section being taken on the line x x, Fig. 1. Fig. 4 is a similar view, the sections being taken on the line y. y, Fig. 1. Fig. 5 is a vertical sectional view of the piston. Fig. 6 is aA perspective view ofthe piston-valve. Fig. 7 is a sectional detail view of the lower end of the pump, showing a modification.
The invention lherein relates to certain improvements in that class of pumps known as boatpumps-. e., such as are employed in pumping boats, barges, flats, Ste-and has for its object such a construction'of pump as will render the same more eiiicient in operation, more substantial in construction, and more easily repaired than the pumps now in use, which are generally formed of wood.
To these ends the invention consists in a pump having a rectangular cylinder, removable valve frames or supports, a piston having a vertically-moving check-valve, and other peculiar features of construction, asmore fully hereinafter described and claimed.
The body A, which is rectangular in form, consists of the sheet-metal sides 2, having their vertical edges bent outward, as shown at 3 in Fig. 3, at such an angle to the body of the sheets that when the latter are arranged to gether in rectangular forni these outwardlybent edges 3 will lap one upon the other, as clearly shown in Figs. 3 and 4. The bent edges 3 are held together by the U-shaped platemetal corner-posts 4, which are slipped into the outwardly-bent edges, and the sides of these U -shaped posts are squeezed together by suitable rolls, so as to tightly compress the edges 3 against each other, thus forming a close hermetic joint between these edges.
The head of the pump is formed by a rectangular cast-iron frame, having its corners reen forced by abutments 5, recessed, as indicated by dotted lilies in Fig. 2, for the reception of the upper ends of the corner-posts. On .three sides of the frame are formed upwardly-projecting flanges 6, the remaining side being provided with a downwardlycurving spout, 7, the iianges 6 being also extended along the edges of the spout, as clearly shown. For the purpose ot' reducing the weight of the headframe, and at the same time obtaining the required height of rim above the surface of the spout, asheet-nietal strip, 8, projecting above the flange 6, is firmly riveted thereto. The upper ends of sheet-metal sides, which project a little beyond the ends of the cornerposts 4, are inserted into the head-frame and riveted to the sides thereof, the ends of the corner-posts being inserted within the recesses in the abutments 5.
The base of the pump is formed by rectangular frame 9, closed on its side by a box, 10, having two inwardly-inclined and two vertical sides. In the upper edge of the frame 9 is formed a groove, 11, (see Fig. 7 for the reception ot' the lower end of the body ofthe pump, where it is secured by rivets. The outside joint between the sheet-metal sides and the frame is tightly packed with lead or other suitable material, as shown; or in lieu of forming the groove 11 in the frame, said frame is made suflieiently large to receive the lower end of the pump-body, and within the body is placed a gasket of heavy metal, the gasket, body, and frame all being united by rivets, as shown in Fig. 1.
In the inclined sides ofthebox are formed openings for the reception ofthe valve-boxes 13, which are provided at one end with iianges 14, for the purpose of securing them in place. On the ends within the pump said boxes are provided with lugs 15, to which are attached the check-valves 16, of the usual construction.
To the lower end of the pump-rod 17 is secured the pyramidal case or shell 18, within which is arranged the similarly-shaped leather packing 19, completely lining said shell and projecting beyond the. edges of the shell, as at 20 in Fig. 5, thereby forming not only a seat or cushion for the piston-valve, but also a packing between the edges of the piston and IOO the sides of the body. Through the sides of the shell and leather lining are formed openings 21, for the ow of water from one side of the piston to the other. On the pump-rod is mounted the pyramidally-shaped metal valve 22, having a rectangular opening through its apex for the reception of the correspondinglyshaped lower portion of the pump rod. Across the upper end of the valve are formed transverse arms supporting the sleeve 23,'
which serves to prevent any lateral tipping or displacement ofthe valve during its lip-anddown movement.
pump, about midway of its length, is arranged a band, 24, which serves to brace the cornerposts 4 as against displacement.
I claim herein as my inventionl. In a boat-pump, the body A., consisting of metal sheets having their outer edges ont- Around the body of the wardly bent, in combination with malleable- 2o firon corner-posts slottedfor the reception of the edges of the sheets, and cast-metal head and bottom pieces recessed for the reception of the ends of the sheets and corner-posts, substantially as described. I 2 5 2. A piston for boat-pumps, having in comy bination a metal shell having inclined sides, an elasticli ning therefor extending beyond the edges of the shell, said shell and lining being perforated, as described, and avertically-slid- 3oV ing check-valve, substantially as described.
In testimony whereof 'I have hereunto set my hand.
CHARLES P. CARLSON.
