Application filed October 23, 1924. Serial No. 745,405.

This invention relates generally to clamping devices, and particularly to a clam ing device which may be associated with exible tubular articles, such as rubber hose, for

the purpose of clamping said rubber hose to such articles as coupling members, ferrules,

' etc. Also, the clamping device disclosed in the present application may be used to clamp radio ground wires to a water pipe or like article.

Briefly stated, my improved clamping delar band will be reduced by such bending operation, whereby the article surrounded by said circular band will be tightly gripped thereby.

members C and D are preferably formedfrom strips of resilient material, which are is a side elevation of one form of.

.In V and VI of the drawings,

of some considerable width, as shown in F g. VI. and said members are provided with strengthening ribs E which extend cir' cumferentially of said members to add rigidity thereto. Formed at an end of the member D is a projecting portion 1, which comprises a pair of legs 2 and 3 formed in+ tegral w1th said member D, said'legs being arranged at an angle to each other so that an approximately V-shaped space is provided between said legs. By referring to F 1g. IV it will be noted that the leg '2 of the pro ecting portion 1'is offset from the wall of the member D. This arrangement results in an abutment 4 being formed, which is'intended for a purpose to behereinafter set forth. It will also be noted from the view mentioned thatthe rib E associated with the member D is extended to a point where a portion D of said rib is assoclated with the leg 2.. The le 3 of the extended portion 1 is also provided with a rib which is designated by thereference character 5. Located'at an end of the member C of the band B is a projecting portion 6, comprls ng a single leg, said leg being rovided with a reinforcing rib 7. Forme integral with the leg 6 is a pair of ears 8, there being one of these ears located at each 7 side marglnal edge of said leg. I 5

Arranged at the end of the member D1 oppos te the end thereof provided with the pro ectlng portion 1 is a pluralit of aper tures 9, and arranged at the end 0 the member C opposite to the end provided with the projecting portion 6 is a hook 1 0. Theend portion of the member C which is provided with the hook 10 is ofl'setfrom thewall of said member C and is reduced in width with relation to said wall of said member 0.15 Also that portion of the member D which 'is; provided with the apertures 9 is channelshaped in'cross section, as shown in Fig. XI, whereby the inner portion of-the hook' 10' will be flush'with theinside' face of theband 100 B when the members D and C are connected together. It is. apparent from the foregoing thatthe diameter of the'band B may be' varied by inserting the book 10 in the various apertures 9, it being plain that theband 1 B would be of much greater diameter when the hook 10 isin an aperture adjacentto the end of the member D'than it would when said hook is in an aperture removed inwardly from the end of said member D.

11 designates a clamping means for securing a wire to the clampln device A, sald clamping means 11 being utihzed when the clamping device is employed to attach a radio ground wire to a grounded artlcle, such as a. water pipe. The clamping means 11 13 produced by cutting a pair of slits 12 and 13 in the member D of'the band B. The material 14 of the member D which is located above the slit 12 and the material 15 which 1s below the slit 13 is bent inwardly, and the material 16 which is located between said slits 12 and 13 is bent outwardly. This provides a space between the bent portions of the member D through which the wire 17 1s passed,and when the band B is drawn tightly about an article, such as a water pi it is lam that these bent portions wil e cause to grl said wire, whereby it will be tlghtly hel and because the band B is made of metallic material an electrical connection will be made between said wire and the article whichis surrounded by said band.

In describing the use of my improved clamping device it will be assumed that it 1s being used to clamp a section of rubber hose to a ferrule. The rubber hose is slipped over the end of the ferrule in the usual manner and the band B of m device is caused to encircle said hose at t e point where 1t encloses said ferrule. If the diameter of the band B is not such that said band fits close to thecircumferential face of the hose, said band may be adjusted by moving the hook 10 into an aperture 9, which will cause said band to have the proper diameter. The projecting portion 6 of the member is, of course, arranged within the approximately V-shaped space between the legs pf the projecting portion 1, as shown in Fig. IV, and said assembled projecting portions are subjected to downward pressure by being hammered or in any other suitable manner, whereby said projecting portions are brought to the osition in w ich they are shown in Fig. This will have the effect of reducing the diameter of the band so that it will tightly grip the article which it sur-' rounds and it w1ll also securely lock the ends of the members C and D together.

After the projectin portions 1 and 6 have been bent as descri ed, the ears 8 associated with the projecting portion 6 will be bent over as shown in Fig. VI, so that they embrace the leg 2 of the portion 1, whereby accidental disconnection of said portions 1s prevented. It will be noted that when the parts are assembled asdescribed. the curved end C of the member C will abut a ainst the abutment 4. This will have the e ect of preventing longitudinal movement of the portions 1 and 6 relative to each other in an inward direction, the interlocked portions preventing longitudinal movement of said portions in an outward direction. When the portions 1 and 6 are interlocked as described, the ribs formed on said portions will rest within each other, as shown in to eac other to provide an approximately 1 V-shaped space therebetween. This form of my device ,is also rovided with a projecting portion 6 simi ar to the projecting portion 6 described, and said pro ecting portion 6 is rovided with integral ears 8*. By

provi ing the band B with a plurality of pro'ecting portions 1" and 1 the diameter of sai band-may be adjusted to fit articles of different sizes, it bein plain that when the portion 6 is inserte into the projecting portion 1 the band will have much greater diameter than if said portion 6' were inserted into the projecting portion 1. The band B is clamped on an article in the same manner 'as is the band illustrated in Fig. IV, the projecting portions 1 and 1 bein bent downwardly to contract said-band an lock the ends thereof together, as shown in Fig. II. After the portions 1 and 1 are bent downwardly as described, the ears 8 are bent to positions where they engage said bent portions to retain said bent portions in the positions to which they have been moved. It is apparent that in addition to the adjustable feature the presence of the pair of projecting portions land 1" will increase the amount of contraction obtained when said rojecting portions are bent downward y In igs. VIII and IX I show another form of my invention in which a single rojecting portion 1 is employed. It wil be noted that the band B is not separable at the projecting portion as is the case with the two forms of my invention already described, but the pair of legs which comprise said projecting portion are formed as unbroken parts of the band. The band shown in Fig. VIII is provided with a hook 10 at one of its ends and a plurality of apertures 9 at its other end, so that said ends of said band may be adjustably connected together, this arrangement being similar to the adjustable feature shown in Fig. IV and already described. The band B is provided with integral ears 8 which are adapted to be bent to retain the projecting portion 1 in its bent position. 1. v Fig. X shows a device comprising a band I B' provided with a projecting portion 1 composed of a leg 2 and a leg 3 arran ed at an angle to each other. Arran ed a jacent to the end-of the band opposite to-the end having tlie'projecting ortion 1 is a plurality of openings, th'ere ing a number of notches at one side marginal edge of said band and a plurality of'enclosed apertures 21 adjacent to the opposite side marthe ends of said band are drawn together,

thus reducing the diameter of said band and causing same to grip tightly the article which it is desired to clamp.

It is apparent that in the use of all of the forms of the device shown and described, the bands may be slipped over the end of the article to be clamped or the ends of said band may be separated from each other "and said band caused to surround the article to be clamped by being moved transversely relative to said article.
