HOSE-COUPLING BAND.

SPECIFICATION forming part of Letters Patent No. 366,532, dated July 12, 1887.

Application filed February 2, 1887. Serial No. 226,963. (No model.)

To all whom it may concern/.- metal which will permit the same to be bent Be it known that I, FREDERICK W. TUERK, into form, as presently explained. Jr., of Syracuse, in the county of Onondaga, The blank A has a straight central portion,

in the State of New York, have invented new B, Fig. 2, and curved ends C C, and is proand useful Improvements in Hose-Coupling vided with the ribbed edges a a, Fig. 1, I) 1), 1'5 Bands, of which the following, taken in con- Fig. 2, and with the oppositelyarranged exneetion with the accompanying drawings, is a tensions E E, Fig. 2, and the ends D D, Figs. full, clear, and exact description. 1 and 2.

My invention relates to improvements in The ribs (1, (l, I) b are provided to strengthen bands for hose-couplings, which are clamped the blanks when bent into form, and the over the hose to secure the coupling therein, curved ends C C are provided in order that and the object is. to provide an efficient and when the blank is bentin shape the bend comes simple device which will evenly clamp the on the straight portion B, thereby permitting hose onto the coupling and securely retain the blank to be shaped withoutweakcningthe 1 the same in position; and to this end my inribbed ends C C. i vention consists in a band of metal, either cast The ribs a a on the curved ends C C of the or struck up, formed with its central portion band are made flaring at c from the central straight and its ends curved, so that it may straight portion, B, of the band A, the flaring be readily bent into form without weakening ribs terminating at the top or upper extremity I 20 the ends, and in strengthening the same by 'of the lugs D when the band is formed into providing ribs on the edges of the band, and shape. The object of thus flaring the ribs is extensions oppositcl y located on the respective to impart great strength and stiffness to the ends, and in providing the ends with recessed lugs D with the minimum quantity of metal and countersunk apertures for the passage of at this point, and the desired resultis thereby 2 the clampingbolt. secured, as the curved ends are unaffected by It consists, also, in the detail construction bending the band into shape, whilethe flaring and arrangement of the parts, all as hereinafter ribs serve as a brace or tie against the draw of more fully described, and pointed out in the the clamping-bolt in clamping the band on claims. the hose L to secure the coupling therein.

0 In specifying my invention reference is bad The ribbed ends C C D D form lugs when $0 to the accompanying drawings, in which, like the blank is bent in shape, as best shown in letters indicatingcorresponding partsin allthe Figs. 3 and 4., and one of said lugs, D, has a views, Figurel is a top plan of the blank from recess, g, between the flaring ribbed edges a which my improved band for hose-couplings a, into which the nut of the clamping-bolt (l- 35 is formed. Fig. 2 is an isometric view showis inserted andheld by the flaring ribbed edges ing the under side of the blank and the curved c a, to hold the nut when the bolt is turned to ends provided with the oppositely-arranged clamp the bandontoahose and coupling. The extensions. Fig. 3 is anisometric view of the opposite lug, D, is provided with the counterblank bent up in shape and provided with the sunk hole f for thehead I, Fig. 4,0[' the clam p- JO clamping-screw, illustrating particularly the ing-bolt G. shape of the recess which holds the nut of the The extensions E E, as will be observed, are clamping bolt or screw. Fig. 4 shows the delocated on opposite edges of the ends D D of vice applied to the hose, clamping the coupthe blank, and when the blank is shaped the ling in position. Fig. 5 is a transverse secsaid extensions E E form tongues which lap 5 tion taken on line mm, Fig. 3. Fig. 6 isaside into the opposite bend of the band and form 5 view of a hose and coupling with the band in a continuous circular clamp, which is rendered place thereon. adjustable orcompressible by tightening up A represents the blank from which my llllor unscrewing the clampingbolt G. proved band for hose-couplings is formed,and The object of providing the projecting 50 the same may be struck up or cast of suitable tongues E is to provide means for compress 10o ing the material of the hose L uniformly,and thus evenly clamping the hose to the coupling.

In all of the bands for hose-couplings now used no provision is made for this purpose, and the band clamps the hose L to the coupling and squeezes the material of whiehvthe hose is composed into a fold between the two jaws or lugs of the clamp, thereby straining the hose out of shape and weakening the same without securely holding the couplingin place; and by frequently tightening and loosening the band the end of the hose becomes frayed out and destroyed, rendering it necessary to cut off the end.

The main difficnltyin the use of the old band results from the insecure and uneven clamping of the hose to the coupling. My invention remedies this defect, for the reason that the extensions E E bear against the hose from opposite sides and exert the pressure equally thereon, so as to tighten or compress the material circumferentiall y and evenly clampthe hose to the coupling. Furthermore, the old band for hose coupling is necessarily. weak at the clamp, for the. reason that the clamp-screw compresses the lugs at the point farthest from the circumference of the coupling, and the tendency is to break the lugs oft, while in my improved band the extensions E E pass under the opposite bends of the band A and underneath the lugs D D, thus affording a circumferential hold entirely around the hose, strengthening and stiffening the lugs, so that .the clamp=screw compresses the band evenly without twisting, and thereby weakening the lugs in the operation.

It will be observed that the projecting ribs b I) leave a channel or recess in the under side The blank A is bent in shape on the straight portion 13, and the bolt G is provided and the device is applied to the hose Lover the coupling N, which is provided with the union M, as shown in Figs. 4 and 6, and the band is clamped securely onto the hose with a screw-driver. the nut H being securely held in the recess 9 against the flaring ribbed edges a a, and the band A may be readily removed by loosening the screw-bolt G. The ribbed edges 1) I) serve also to compress the material of the hose against the thread of the coupling N, thus serving to provide a very secure connection of the coupling to the hose.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isl 1. As a new article of manufacture, a hose coupling band formed of metal having oppositely-arranged extensions on its ends interlocking with ribs formed on the inner edges thereof, anda clamp-bolt passing through lugs on the ends of the band to secure the band on 'the hose-coupling, substantially as andfor'the purpose set forth.

2. The combination of the band A, having oppositely-arranged projecting extensions E E, ribs 1) b on innerside adjacent to the extension E, ribs'a on outer side of the band, lugs D D, recess 9, for the nut H,and the bolt G, all substantially as and for the purpose set forth.

3. The east-metal hose-coupling band A, having extensions E E, oppositely arranged on the ends thereof, ribs 11 on the inner side of the band, lugs D D on the ends, andstrengthening-ribs a a, flaring to the top of the lugs,

substantially as and for the purpose set forth.

Intestimony whereof-I have hereunto signed my name, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 31st day of January, 1887.
