TUBING FOR AIR-PUMPS.
Specification of Letters Patent.
Patented Nov. 12, 1918.
Application filed December 15, 1916. Serial No. 137,074.
To all whom it may concern:
Be it known that I, GEORGE W. KELLOGG, of the city of Rochester, county of Monroe, and State of New York, have invented certain new and useful Improvements in Tubings for Air-Pumps; and I hereby declare the following to be a full. clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.
My present invention has for its object to provide certain improvements in the construction of pumps, particularly air pumps intended to be used for inflating pneumatic tires, the novel features of which will appear more fully in the following specification, and will be pointed out particularly in the claims appended hereto.
In the drawings:
Figure 1 is a front elevation of the joint of the tubing for the cylinders of an air-pump constructed according to my invention, and
Fig. 2 is a cross section of the same.
Similar reference numerals throughout the drawings indicate similar parts.
The tubes 1 for an air-pump constructed in accordance with my invention may be made of any convenient or preferred length or diameter and are closed at their ends by any suitable or convenient means. The cvlinders are preferably constructed from fiat sheet metal plates, which are rolled. or other- -wise formed to cause the edges thereof to meet squarely, or abut each other, thus forming a butt joint as indicated at 2. Certain disadvantages exist in a joint of this character. owing to the ditlicultv which has been experienced in rendering the joint airtight throughout its length, and also providing the necessary strength or rigidity, as it has been fou d in practice that a tube havin a joint of this character is weak along the io nt. and when it is closed by soldering the joint proper. it is also diliicult to maintain the inner surface of the tube free from ob truction. In order to overcome these diiiiculties, I provide a reinforcing strip 3 on the exter or of the tube. formed of a strip of metal which may be thinner or of lighter gage than the sheet from which the tube is formed. The edges of this strip are folded over as indicated at 4, the bending occurring in a direction away from the body of the tube. This doubling or folding over of the metal accomplishes a further result, which is more important than that of merely strengthening the strip, in that it provides a I smooth curved surface lying in close engagement with'the curved wall of the cylinder and forming a longitudinal V-shaped depression 5 for the reception of the solder.
The formation of a joint strip in the form The formation of a joint of this character, in
which the edges of the plate are first butted together and then secured by a longitudinally extending exterior strip, may also be employed in making the pump cylinders of tin plate, the required interior smoothness of the tubes being assured, and the maximum strength obtained at a minimum cost.
An air-pump embodying my invention possesses the advantages of durability and serviceability united with cheapness in the cost of manufacture.
I claim as my invention:
1. An article of manufacture comprising a cylindrical tube formed by bending a metal sheet to abut the edges thereof to form a longitudinally extending joint and a strengthening strip overlying the joint formed with bent over edges and solder applied between said edges of the strip and tube at opposite sides of the joint.
2. An article of manufacture a tube composed of sheet metal bent into cylindrical form to cause the ed es of the sheet to form a butt joint and a strip applied over'the joint having its edges bent over in a direction outwardly from the tube and soldered thereto.
3. An article of manufacture composed of a tube formed by bending into cylindrical form a sheet of tin-plate and a binder applied over the adjacent edges of the latter formed of a strip of tin-plate having its edges bent over in a direction outwardly from the tube and solder applied at the ed es of the strip and adhering to the tin surfacing of the binder and tube.
GEORGE W. KELLOGG.
