CLAMP.

Application filed December 29, 1928. Serial No. 329,181,

" I ing the ends of the clamp releasably together.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other ob ects 1n View, which will appear as the description proceeds,

the invention resides in the combination and.

arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is ciaimed, changes the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in elevation a device constructed in accordance with the invention, parts being in section;

Figure 2 is an elevation wherein the device is shown at right angles to the disclosureof Figure 1;

Figure 3 is a plan;

Figure 4 is a perspective View showing the latch.

The device forming the subject matter of this application includes an annular clamp 1, which may be a metal band having some resiliency. The clamp 1 is provided with outstanding arms 2 and 3, the arm 2 having an opening 4, and the arm 3 having an opening 5, the opening at preferably being a little larger in diameter than the opening 5. The clamp 1 is shown as being provided with oppositely disposed inwardly extending ribs 6 which serve to increase the hold of the clamp on the article which is within it--although the ribs 6" may be dispensed with, if desired.

The numeral 7 designates a latch made out of rigid metal, and includinga body 8, in the form of a bar having teeth 9. Atom end, the body 8 is provided with a thickened stem 10 having a transverse foot 11, the foot 11 and the stem 10 being disposed at an acute angle to the body 8. The rear surfaces 12 of the teeth 9 are inclined with respect to the body 8 of the latch 7, but the forward surfaces 14 of the teeth'9 are disposed substantially at rightangles to the body 8. I V

In practical operation, the clamp Which is placed around the object to be gripped, and the body 8 of the latch 7 is thrust through the holes 4 and 5, the footll bearing against the arm 2. When the arms 2 and 3 are moved toward each other, the arm 3 slides over the inclined surfaces 12 of the teeth 9, and, ulti -mately,engages with the surfaces 1 1 of one of the teeth, as shown in Figure 1. The clamp will, thus, be held securely about the object to which it is applied.

In order to loosen the clamp 1, it is necessary merely to tap the free end of the latch 7 outwardly, in the direction'of the arrow A in Figure 1, whereupon the latch will swing with the point of engagement between the foot 11 and the arm 2 as a fulcrum, and disengage the tooth of the latch from the arm 3. Owing to the fact that the stem lO is provided with a transverse foot 11, the latch 7 is prevented from swinging and disengaging the tooth from the arm 3.

1. Having thus-described the invention, what 1s claimed 1s':

1. A device of the class described, comprising a clamp having outstanding arms provided with openings, and a latch bar extended through the openings, the bar having teeth engaging one arm, and bcing'provided with a foot bearing on the other arm, the latch bar being freely rem'ovaole' from the openings.

2. In a device of the class described, a clamp having outstanding arms provided with openings, and a latch her extended through the openings, the latch bar having teeth engaging one arm, and being provided with an angularly. disposed stein having atransverse foot. engaging the other arm.

In testimony that we claim the foregoing as our own, we have hereto affixed our signatures.

BENJAMIN n. SAGENKAHN. HAROLD SEAVERS.
