Specification of Letters-Patent.
Patented Jan. 27, 1920.
Application filed January 20, 1919. Serial No. 271,979.
useful Improvements in Hose-Menders, of
which the following is a specification c ontaining a full, clear, and exact description, references being had to accompanying drawings, forming a part thereof.
My invention relates to certain new and useful improvementsin hose menders and has for its primary object the construction of a mender of two parts, the same belng united together and capable of being .applied to a hose and mending the same w1thout the operation of any special tools, and further a mender which can be cheaply manufactured and easily applied to the hose and if desired, removed therefrom.
In the drawings: y
Figure 1 is side elevation, showing my device as applied to a hose.
Fig. 2vis a longitudinal section of the same.
Fig. 3 is a side view of my improved mender before being applied to the hose.
Fig. 4 is an end view of my invention before being applied.
Fig. 5 is an enlarged fragmental section showing the Amethod of securing the shell and coupling sleeve together.
Referring to the drawings, 6 indicates the two sections which are to be connected in the operation of mending the hose. The'mender comprises a coupling sleeve 7 whlch 1s provided on each end with shoulders 8 and intermediate said shoulders is an integral rib 9, said rib being provided witha peripheral.
11 indicates a cylindrical shell in which the rib 9 of the coupling sleeve 7 .is adapted to snugly iit. This cylindrical shell is made out of sheet metal and is secured to the rib 9 by being upset at certain points throughout itscircumference as at 12 by means of a center punch or any other suitable instrument.
' By means of forcing the shell inward as at 12, a portion of the metal of the shell is forced into or seated in the groove 10 which rmly unites the shell 11 to the rib 9. One end of the shell 11 is provided with a series of rectangular slots 13 and the opposite end 1s provided with a series of slots 14. These slots, as it were, are staggered or offset relative ,to each other. By the formation of the slots 13, a series of tongues 15 are formed and by the formation of the slots 14, a series of tongues 16 are formed, which are llkewise staggered or offset relative to each other,-that isto say, the slots 13 are centrally opposite the tongues 16 and the slots 14 are centrally opposite the tongues 15.
The ends of the tongues 15 and 16, when bent downwardly to clamp the hose members 6, lie in a plane struck through the front parts of the shoulders 8, as illustrated in Fig. 2. Before the mender is applied, these tongues are slightly forced outwardly as illustrated in Fig. 3, so as to permit the' insertion of the hose sections.
In the operation of mending or connect-4 ing a hose, the ends of the coupling sleeve 7 are inserted into the ends of the hose sections and then the tongues 15 and 16 are bent downwardly by any suitable instrument until they firmly engage the exterior surfaces of the hose sections as illustrated in Fig. 2.
The coupling sleeve 7 is preferably cast and as previously stated, the shell 11 is formed of sheet metal. The ri'b 9 not only answers as a means to firmly secure the shell 11 to' the mender, but also acts as an abutment for the ends of the hose sections as A illustrated in Fig. 2.
It will be observed that the rear surfaces of the shoulders 8 are rather abrupt so that when the tongues 15 and 16 are bent downwardly, the hose sections 6 are given a rather abrupt bend as at 17.
A mender constructed according to my improved device is cheaply manufactured and cheap to install and firmly unites the hose sections. If it is desired to remove the mender, this may be accomplished by inserting an instrument in the slots 13 and 14 and bending up the prongs so that they are disengaged from the hose sections.
My improved mender is adapted to mend hose of different ply or thicknesses. It is made for the heaviest hose and by bending beyond the exterior surface oftlre liose and tongues mounted on said rib lnd secured does not form an appreciable obstruction thereto by forcing a portion of the metal on the hose. into said groove.
Having'` fully described my invention; In testimony whereof, I htve signed .my 5 what I claim is: name'to this specification, in presence of two 15 A hosev mender comprising a coupling subscribing Witnesses. sleeve provided on each end with a, shoulder FREDERICK HACHMANN. and intermediate the end shoulders ,with an Witnesses: integrals rib provided with :t peripheral EDWARD E.- LoNGAN,
