AS PIPE COUPLING.

i two was M W MM a plings; and I do hereby declare the follow- 7 KEYED ANT SAMUEL sonwnn, or ivnwYo n; x.-
- GAS-PIPE conrnmd.
Specification of Letters Iatcnt.
Patented Oct. 22,1912;
To all whom it may concern:
Be it known that I, SAMUEL Sonwnn, a citizen of the United States, residing at New York, in the county of New York, State of New York, have invented certain new and useful Improvements in Gas-Pipe Couing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in gas pipe couplings.
The prlncipal ob ect of the invention is to provide a positive means for holding a gas tube in engagement with the nipple of a gas jet or-stove, and thereby eliminate all danger of the tube becoming accidentally detached.
Another object of the invention is to provide-a coupling for the purpose set forth which may be used in connection with the style of nipple now in common use.
A further object of the invention is to provide a coupling of the character described which will permit of the hose being readily attached. to or detached from a nipple.
A still further object of the invention is to provide a coupling of the character de-.
scribed which 1s composed of a minimum number of parts, is therefore simple in construction, and is cheap to manufacture.
With these and other objects in View, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims hereto appended; it bein understood that various changes in the orm, proportion, size and minor details of construction Within the scope of the claims may be resorted to without departing from -the spirit or sacrificing an of the advantages of the invention.
n the drawing: Figure 1 is a top plan view showing my improved coupling associated with a stove nipple, Fig. 2 is a longitudinal sectional view therethrough, Fig. 3 is-a side elevation of the coupling, Fig. 4 is a perspective view of onef'of the clamping elements, and Fig. 5 isa longitudinal sectional view showing the application of the coupling to a gas jet nipple, the nipple being shown in elevation.
is designated as a whole by the reference letter A, and this coupling includes an open ended hose gripping tube 9 which is longitudinally slotted, as at 10, and'is formed With an inwardly extending clamping end 9 adapted for gripping the hose 8, as will be hereinafter explalned. Extending laterally from the opposite end 9? of the tube and arranged diametrically opposite each other are perforated ears 1111. Opposed semicircular clamping elements 12-12 are formed from sheet metal, and projecting centrally from one edge of each element is an car 13 which is pivotally connected to a respective ear 11 of the tube 9 by means of a pin. The outer end of each element 12 is formed with an inwardly extending flange 15. The ends of each element are centrally formed with semi-circular recesses 1616. Disposed on opposite sides of each pair of ears 11 and 18 is a' pair of coil springs 17 17, one end of each spring being fixed to a respective clamping element 12 and the other end fixed to the tube 9 so as to normally urge the clamping elements toward each other.
7 In practice, the hose 8 is fed through the slotted tube 9, and has its free end engaged with the nipple 5.' While the hose is thus being attached to the nipple the operators 'fingers spread the clamping elements 12 against'the tension of the springs 17 so as to position the same around the valve stem 7. As soon the clamping elements are released, the spring 17 will cause the clo ments to move inwardly and the recesses 16 of said elements will conj'ointly receive the opposite ends of said valve stem and thereby retain the coupling A against accidental displacement.
- By referring to Fig. 5
to a gas jet nipple 18 whenever so desired. What is claimed is: 1. In a gas pipe coupling, the combination with a hose gripping element formed from a longitudinally split tube, one end thereof being inwardly curved to frictionally grip the hose, of opposed nipple engaging jaws a will be observedthat the coupling A can be readily attached m its outer end with an inwardly extending mezmo sgectively liavii one and connected to a jaw and he other end to the tube for nor mally urging the jawstowm'd each other.
