HOSE-CLAMP.

' Specification of Letters Patent.

' Application filed May 21, 1915. Serial No. 29,510.

which it appertains to make and'use the same.

This invention relates to a new and useful hose clamp, and an object of the invention is to provide a simple, efficient and practical hose clamp involving improved features of construction.

One of the features of construction is the provision of a clamping band having itsadjacent ends terminating in laterally extending loops provided with openings to receive a bolt including a nut for drawing the ends toward each other.

Another feature of the invention is the provision of a tongue, over which the adjacent end of the band lap, said tongue having a lug to be engaged by a part of one of the looped ends to prevent movement of the tongue in one direction, there being lugs upon opposite edges of the tongue overlying the band and extending laterally in engagement with one of the lateral loops, to not only secure the tongue to the band adjacent one of the looped ends and to prevent movement of the tongue in the oppo site direction, but to also constitute means to retain the nut against unscrewing.

Another feature of the invention is to provide the tongue with enlarged openings in both of its ends to prevent creeplng or buckling of the tongue when the band is under strain on the hose. These openings also permit the ends of the tongue to sink into the rubber easily, thereby preventing any possible opening at this point when the band is on the hose.

In practical fields the details of construction may necessitate alterations, falling tional view transversely of the hose clamp on line 3-3 of Fig. 2. Fig. 4 is a detail view of the tongue. Fig. 5 is a detail view of one end of the band.

Referring more especially to the draw ings, 1 designates the hose, and 2 the clamp, WhICh may be constructed of any suitable material of a spring nature. Each end of the band is bent at 3 to form a lateral part 4, which is folded at 5 to form a loop 6 and another part 7, which is at a slight angle to the part 4. Each part 7 is bent at 8 to form a part 9 extending toward and.

terminating adjacent the bend 3. The parts 4 and 7 are provided with registering apertures 10 and 11, to receive the bolt 12, and

the aperture 11 is of sufficient elongated contour, in order to extend partially into the part 9 of the loop, as shown at 13.v A tongue 14 is provided over the opposite ends of which, the end portion 15 of the band overlap, and formed upon the tongue is a lug 16, constructed by indenting the tongue from its under surface. This lug 16 engages the portion 13 of the aperture 11, in order to prevent movement of the tongue in the direction of the arrow at. Extending from the opposite edges of the tongue are lugs 17, which are designed to overlap the end portion of the band behind the part of.

the loop, thereby preventing movement of the tongue in the opposite direction. These lugs 17 are also designed to be extended laterally forming extensions 18, subsequently to the lugs being extended toward each other. The extensions-18 are parallel to each other and engage opposite edge portions of the nut 19 of the bolt 12, thereby preventing displacement of the nut. The opposite ends of the tongue are provided with enlarged openings or apertures 20, in order to permit the ends of the tongue to sink into the rubber easily, thereby preventing creeping or buckling of the tongue when the band is under strain on the hose, and also prevent any possible opening at this point.

The invention having been set forth, what is claimed as new and useful is 1. A hose clampcomprising a clamping band having laterally extending loops at its adjacent ends, each loop having an aperture, a tongue underlapping the adjacent end portions of the band and provided with a lug engaged by a part of one of said loops to prevent movement of the tongue in one direction, a bolt extending through the apertures of said loops and provided with a nut, the opposite edges of the tongue adjacent one of the loops having oppositely disposed ears extending toward each other and overlying the band behind the said one of the loops to prevent movement of the tongue in the opposite direction, said ears having lateral extensions also engaging behind the said one of the loops and engaging opposite edge portions of the nut to prevent displacement and movement of the nut.

2. A hose clamp comprising a clamping band, the adjacent end portions of the band being bent to form laterally extending loops, one side of each loop being bent and extending toward the first bend, the oppo site sides of each loop having registering apertures, the aperture in the side of each loop which is bent toward the first bend being elongated, an elongated tongue underlying the adjacent end portions of the band and having a lug engaged by the edge of one of the elongated apertures which extends partially into the bent part of one side of one of the loops to prevent movement of. the

tongue in. one direction, the opposite edges of the tongue adjacent the said one of the loops having oppositely arranged earsv extendin toward each other and overlapping one en portion of the band behind the said one of the loops to prevent movement of the tongue in the opposite direction, said ears having extensions extendingv laterally and in parallelism behind the said one of the loops, a bolt extending through the apertures of the adjacent loops and having a nut interposed between said extensions, which act to prevent movement and displacement of the nut, the opposite ends of the tongue having enlarged apertures to permit the hose to expand therein to prevent creeping of the clamp on the hose.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
