TUBE TESTER Filed April 20. 1926 BY P (Q A ATTORNEY Patented Mar. 31, 1931 PATENT CFFICE PHILIP L. OBRIEN, F LOWELL, MASSACHUSETTS TUBE TESTER V.application led Apr-i120, 1926. Serial No. 108,205.

I-Ieretofore when tubes have been tested for slow leaks, it has been necessary to inflate them to some extent and often the extent has been sufficient to cause a bursting of the tube.

The object of my invention is to provide a device in the form of a net which may be secured so as to prevent burstingand be immersed in a tank along with a tube so that imperfections in the tube may be revealed without danger of bursting the tube.

For a more detailed description of myinvention reference is to be had to the accompanying drawing, forming a part hereof, in which Figure l is a side elevation of an inflated tube provided with my protecting net.

Figure 2-is a view showing the net and rings in an extended form.

Figure 3 shows how one ring is passed A through another, and

Figures 4 and 5 are sectional views showing the relation between the rings, the net and the tubes, Figure 5 being an enlarged section to more clearly reveal the structure.

ings, similar reference characters designate similar parts.

My improved tube tester 1 is adapted to be put about an inflated tube 2, as above set forth, to protect it while being tested.

` This tester consists of two rings 3 and 4: which are somewhat resilient as they are made of metal and they are joined by netting 5, as indicated, one ring being at each edge, as shown in Figure 2. When in use a tube 2 .may be slightly inflated so as to make it so that it can be handled easily and then the tester is placed, as shown in Figure 3, and thereafter one ring, say the ring 3, the ring when the ring 4 is placed at an angle as shown Throughout the various views of the draw- 3 being sufficiently resilient to permit this broad enough to cover all structures that 55.

come within the scope of the annexed claims.

Having thus described my invention, what I claim is:

l. A tire tube tester comprising a pair of rings, a netting secured to said rings, said rings being of such size that, when parallel, one may not be passed through the other, but one ring beingl adapted to be so passed through the other ring by lrelative inclination and bending in order to secure the netting about the tube.

2. A tire tube tester consistin of an endless net formed of cord, flexible rings to which the edges of the net are secured, said rings being of common diameter and adapted to be sprung one through the other to interlock the net into a tubular formation.

3. A tire tube tester comprising a pair of rings, a netting connected to said rings, said rings being of such size that, when parallel, 5 one may not be passed through the other, but one of said rings being 'flexible so that Lit can be passed through the other ring by relative inclinationy and bending in order to secure the netting about the tube. l.

In testimony whereof, I have hereunto set my hand and seal this 6th day of April, 1925.

PHILIP L. OBRIEN.

in Figure 3, is passed through the ring 4 and thereafter the tube 2 is further inflated after which the net, rings and tube may be tested in the usual way while fully protected by the netting 5 whichis secured snug against it by the inflation of the tube while held in the netting. After the tube has been duly tested by a-reverse operation, the netting may 5 put in a tank 6 with water 7 and the tube'
