LEO A. BRIGEL, OF CINCINNATI, OHIO,.ASSIGNOR, BY MESNE ASSIGNMENTS,

TO LEO A. BRIGEL, J R., AND EDWARD J. BRIGEL, TRADING UNDER FIRM- NAME OF CINCINNATI PUMP COMPANY, OF CINCINNATI, OHIO.

CHAIN-PU MP.

SPECIFICATION forming part bf Letters Patent No. 700,729, dated May 27, 1902.

Application filed September 17,1898. Serial No. 691,275. (No model.)

To all whmn it may concern.-

Be it known that I, LEO A.'BRIGEL, a citizen of the United States,'residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certainnew and useful Improvements in Chain-Pumps, of which the following is a specification.

My invention relates to certain improvements in chain-pumps, and more particularly to in the tubes and reservoirs used in pumps of this class; and the object of my invention is to simplify and cheapen the construction of such parts, while at the same time making them strong and durable. My invention consists in certain novel features of the construction, combination, and arrangement of the tube and reservoir whereby certain important advantages are attained, and the device is made simpler, cheaper, and

otherwise better adapted and more convenient for use, all as will be hereinafter fully set forth. 7

The novel features of my invention will be carefully defined in the claim.

In order that my improvements may be the better understood,'I have shown in the accompanying drawings a tube and reservoir constructed according to my invention, in which drawings- Figure 1 is a side elevation showing the tube and reservoir attachedthereto, parts of the tube being broken away for lack of space. Fig. 2 is an enlarged transverse section taken through a curb having a curved wall and showing myimproved reservoir in place therein. Fig. 3 is an enlarged section taken axially 5 through the reservoir and tube and showing the means for securing these parts together- Fig. 4: is an enlarged detail bottom view show- 40 ing the form of the bottom plate of the reservoir before it is secured thereto. Fig. 5 is an enlarged transverse section taken through the tube and showing a button in place in the same. Fig. 6 is a sectional view similar to Fig. 2, but showing the arrangement of the improved reservoir in a curb having a straight or flat wall.

As shown in the views, the tube is formed in sections 1 and 2, connected by means of coupling 3 ma well-known way and is provided at its lowerend with a flared or funnelshap'ed'mouth 4, adapted to facilitate the entry of the buttons into the tube and also serving to protect said lower end of the tube from being excessively worn by the chain.

5 indicates the reservoir, made in elongated form from sheet metal, the corners of said reservoir being beveled or flattened, as shown at 6, so as to give it an octagonal form in cross-section. The edges of the metal sheet of which the reservoir is formed are doubleseamed together along the back of the reservoir, as shown at 7 in the drawings.

8 indicates the bottom of the reservoir, also made from sheet metal and having its outer edges flanged, as shown in Fig. 4, said flange being notched at each corner to permit it to be bent and double-seamed" to the lower edges of the reservoir 5, as clearlyshown at 9 in the sectional view, Fig. 3, and said bottom plate S is alsoformed with a central circular opening adapted for the passage of the upper end of the upper section 2 of the tube, around which opening is formed a depending integral flange or lip 10, adapted to fit closely to the sides of the tube. 3

The tube is formed from sheet metal bent to a circular form in cross-section and having its edges preferably united by flanging and double-seaming to produce a rib 11, extend- 8o ing longitudinally down the outside of the tube at one side, which ribll is received in a socket 12, formed within'the flange 10 at one side of the opening in the bottom of the reservoir when the latter is secured to the tube.

On theoutside of the tube diametrically opposite to therib 11 is produced another outwardly-projecting longitudinal rib 13, formed by pressing or bending out the side of the tube from the arc of a true circle, and said rib o 13 is adapted to be received in a socket 14, formed within the flange 10 at the side of the opening in the bottom 8 of the reservoir opposite to the socket 12.

In order to secure the reservoir to the tube, 5 the end of the latter is passed through the opening in the reservoir-bottom, after which a flange 15 is formed on the tube within the reservoir by expanding the inserted end of the tube, so as to prevent the withdrawal of the same from the opening. Solder is also applied around the lower edge of the flange 10, so as to hold the tube and reservoir firmly together. These parts may also be secured together by turning the flange 1O upwardly within the reservoir (instead of downwardly on the outside thereof, as shown in Fig. 3) and double-seaming it with flange 15, in which case I prefer to press the parts together, so that the flange 15 will be fitted into a depression in the bottom formed around the central opening thereof, making said flange flush with the interior exposed surface of the bottom 8 of the reservoir. When so constructed, the solder may be entirely omitted.

A channel 16 is formed within the tube by the bending of the wall of the latter to form the rib 13, and said channel extends longitudinally through the tube and is adapted to allow the water held in the reservoir and in the upper part of the tube to flow past the buttons (indicated at 17 in Fig. 5) down into the cistern after the chain ceases to move, so as to prevent the water from freezing in the tubes and reservoir in cold weather and also from becoming stagnant in warm weather, as will be readily understood. y

In Fig. 2 I have shown the reservoir applied to a curb made from sheet metal and having a curved end wall 18, outside which is arranged a casting 19, having a spout 20, one end 21 of which passes through an opening in the curb and also through an opening 22, cut in the front face of the reservoir 5, as clearly shown in Fig. 1. The opposite sides of the casting 19, which is curved to fit flush on the outside of the curb, are perforated for the passage of the ends 23 of a yoke or stirrup bent from a bar or rod of metal. Said ends are screw-threaded to receive nuts 24: outside the curb, and the central part 25 of the stirrup is arranged to fit in a transverse crease or recess 26, formed inthe back of the reservoir opposite the opening 22, so that when said nuts 24 are screwed home the reservoir will be clamped tightly in place within the curb.

By makingthe reservoir with flattened front face and beveled corners the same is given secure bearing against the inner surface of the curb, since said construction provides two points of engagement between the parts extending the full length of the reservoir at each side of said flattened front surface, and said construction also permits the reservoir to be used in a curb having a fiat end wall,

as shown at 27 in Fig. 6, the flattened front side of the reservoir resting in this case directly against the fiat inner surface of the curb-Wall 27.

28 indicates the casting,formed to fit against the outside of the curb-wall and having a spout 29, one end 30 of which passes through an opening in the curb-wall and also through an opening in the front side of the reservoir, as above set forth. The reservoir in this case is held in place by means of a stirrup like the one above described.

In mounting the reservoir and tube Within the curb the parts are so arranged that both the ribs 1l and 13 on the pump-tube are in the plane in which the strain of the chain moving over its wheels is exerted, so that both of said ribs act to impart strength to the tube to enable it to resist such strain. In this way a considerable economy in the use of metal is effected, since it is rendered possible to use metal of much less gage than would or stopped up, but is kept open and clear from bottom to top by pressure of the buttons sweeping along its entire length. It will also be obvious from the above description that my improved tube and reservoir is capable of some modification without material departure from the scope and spirit of myinvention, and for this reason I do not wish to be understood as limiting myself to the precise form and arrangement of the parts herein set forth.

Having thus described my invention, I claim- A tube havinga longitudinal seam extending along one side and forming an exterior strengthening-rib, and having at its opposite side an outwardly-bent portion forming a longitudinal strengthening-rib outside the tube and also forming inside the tube a longitudinal channel, substantially as set forth.

LEO A. BRIGEL.
