Description

FOR OH A 1 This invention relates to a means for securing a on a coupling with a socket and a sleeve mounded around said said sleeve clamping the socket with its inner wall onto a part of the which is slipped on the tubular portion of the coupling It is intended to provide a securing means which after removal and which can be applied without expensive auxiliary apparatus and in a short so with cost of Clamping of the securing means on the hose with always the same force should be made possible if this clamping force is changed after some the securing means should be adjustable on the desired clamping force present invention consists in device for fixing a on a tubular portion of a coupling member comprising a split socket and a said socket and sleeve bdng made of a relatively weak the outer side of the socket the inner side of the sleeve being conically tapered in conformity with each other for clamping the socket with its inner wall onto the part of the slipped on said tubular portion of the coupling member and a metal ring being claimped around the The outer wall of the socket and the inner wall of the sleeve are preferably provided with cooperating screw The clamping force exerted by the securing means is dependent now on the degree in which the sleeve is screwed the In order to easily clamp the socket on the hose and to divide the clamping force evenly over a surface of the according to the present invention the socket wall may be cut through and ably this cleft is order to provide a cheap securing accordin present socket and the sleeve may be made of synthetic According to the present the sleeve provided with external for coupling chain tongs and thereby the sleeve can be easily screwed on the In order to spare secured hose near the securing sleeve near the o the conical inner with the diameter may be provide ith an annular the end face of that sleeve end being rabl rounded off The present invention will elucidated the following description o of the securing means as indicated in the enclosed Figure 1 is an axial section of this is a axial section of the docket as applied in the securing according to figure figure 3 is section of an embodiment of a as this can applie in the securing means to figure As appears from figure 1 on end of a is slipped o tubula portion of The invented securin meaner according to the embodiment comprises socket which engages the part of the tubular portion 1 of the socket 2 is on inner wall provided with ridges 6 and 7 cooperatin with in tubular portion 1 of the coupling Said socket also be provided on its inner wall annular ribs 8 and 9 as indicated in figure riba as well as said ridges serving to retai the hose against axial A sleeve 4 is applied around the socket 2 and clamps on a ring 5 being clamped around the sleeve 4 in order to radially support said In order to mount the sleeve 4 on the socket 2 and to adjust the clamping force o the sleeve 4 on the socket 2 and fore of socket 2 on the outer side of the socket the inner side of the sleeve conically tapered in conformity with each the largest diameter being near the coupling On the grounds also the outer vail of socket and the inner wall of the are provided with cooperatin screw thread 11 and 12 for this reason the socket and in order to prevent driving which could result in of the cleft is the 10 a as indicated in figure Screwing the sleeve 4 on the socket 2 can be tated if longitudinal strips 13 with screw thread on th socket 2 are alternated by recesses 14 as indicated in figure In order to be able to screw the sleeve onto the socket means 2 b of chain sleeve is provided with teeth 15 near the end of the smallest inner said teeth being arranged around the and extending radially outwards as indicated in figure Wear of the hose 3 resulting from rubbing of hose against the walls of the socket 2 and sleeve can be prevented by of an interna annular ridge 16 by the inner wall of the sleeve near the end the smallest the end face 17 of that sleeve end being rounded off is an important feature o invented securing that the socket 2 and sleeve 4 are made of for instance Synthetic is not only cheaper than but a body like the socket 2 with the screw thread the ridges and the ribs 8 and 9 eventually recesses 14 can be casted synthetic material more easily and This also applies for the sleeve with the screw thread the ridge 16 and the teeth According to the present invention the sleeve 4 of material is radially supported by the metal ring so that also with respect to radial strength of the sleeve there cannot be any objection against synthetic insufficientOCRQuality

Claims

35711/2 : Claima

1. A device for fixing a fire-hose on a tubular portion of a coupl member comprising a split socket and a sleeve , said socket and sleeve being made of a relatively weak non-corrosive material, the outer side of the socket and the inner side of the sleeve being conically tapered in conformity with each other for clamping the socket with its inner wall onto the part of the fire-hose slipped on said tubular portion of the coupling member and a metal ring being clamped around the sleeve.

2. A securing means according to Claim 1, characterized in that the socket has been split along a V-shaped line.

3. A securing means according to Claim 1 or 2 characterized in that the outer wall of the socket and the inner wall of the sleeve are provided with cooperating screw thread.

4. A securing means according to Claim3, characterized in that longitudinal strips with screw thread on the socket are alternated with recesses.

5. A securing means according to any one of the preceding claims, characterized in that the socket and the sleeve are made of synthetic material. f: any A securing means according to/one of tho x>roceding clttiraa, characterised in that the sleeve is provided ,ith external teeth for coupling to chain tongs. ΰ.A securing means according t foKe of the preceding claims* characterised in that the sleeve near the end of the conical inner wall with the smallest diameter is provided with an internal, annula ridge, the end face of that sleeve end being rounded off inwardly. securing means substantially as described in the iption and/or represented in the drawing.
