IMPROVEMENT IN CLAMPS FOR STOPPING LEAKS IN HOSE-PIPE-S.
Specification forming part of Letters Patent No. 42.735, dated May 10,- 1864-.
To aZZ'wwm it may concern.'
Be it known that I, OIIEIs'rIAN RUBsAM, of Newark, in the count-y of Essex and State of New Jersey, have invented a new and Improved Clamp for Stopping Leaks in Hose; andl do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accom panying drawings, forming a part of this 'specilcatiom in Figure l represents a plan or top view ot' greatly dii'ering in size the width of the canyasorother'material has to be increased or decreased according to circumstances, but twp orthree clamps of different sizes will be salcient to meet all contingencies.
To the ends of the canvas or leather A- two strips, B, of metal are Iirmly secured by means of' rivets or in any other desirable manner,` and these pieces oi' metal are provided with lugs a, one of which is provided a with a screwthread to lit to a screw, b, and the other with a hole through which said screw passes freely. If a leak occurs in a hose the screws b are taken out, the clamp is placed on the leak,
and by reinserting the screws itfis drawn up tight, so that no water can find. its way out between the hose and clamp, and for all practical `purposes thc hose is rendered just as good as new.
For the body of the clamp I prefer canvas to leather or other material, because the canvas, onbeing attached to a leak when it becomes wet, shrinks and draws np tighter and tighter to the circumference of the hose, whereas leather, on becoming wet, stretches, and it' not tightened up repeatedly, allows the water to leak out at the ends.
With this clamp a leak in a hose extending twothirds round, or more, can be readily stopped, and the delay caused by the operation of attaching the clamps is so small that the hose can be used almost without interruption. It is only necessary to stop the stream for a few minutes, and it a hose burst while playing on a tire, the fire is not permitted to make great headway while the leak is being ent, as an improved articleot' manufacture- A leak-clampi'or hose-pipes, composed of the canvas or fabric A, with attached metallic strips B and clampingscrews b, made and operating as herein shown and described.
