I MANDREL Filed June 8, 1950 INVENTORS.
I} RENE P. PIPEROUX I JOHN N. BIRMINGHAM Patented Jan. 22, 1952 UNITE D PATE'N T OF F I CE v mingqham, Niltley N'. J., assig'nors to Celanese Corporation of America, New York, N. Y., a
corporatlbn of'Dela-ware Application-June;8;.1950,Serial:N0s166;353:
This invention relates-to mandrel's and, relates. more particularly to a mandrel. adapted to engage and support a tubular memberv such. as. a,.weh.- supporting core.
When materials such as film, r011; paper. flab..- ric and the like are produced and processed in the form of a web,. it isv commonto wind said. materials onto a tubular core to assist in. handling, storing. and. shipping, the, same During. the winding operation,. thetubular corev ismounted on a mandrel. which. acts both. to supportthe tubular core in the winding apparatus. and to transmit thereto. the driving force necessary.. to rotate thev same. To obtain satisfactory results. the mandrel must engage the. tubular. core. firmly so that there will bev no slippage between. the. two during. the winding. operation. In addition,. the mandrel must be constructed so. that the tubular core may be mounted thereon and. removed therefrom quickly and without difficulty. and so. thatv the tubular core will be concentricwith the. axis. of rotation of the mandrel. The, means. employed. to engage the tubular core. should not. damage. either the inside or outside surface of. said core. and should align the. tubular core properly with. respect to. the web of material. being woundj thereon.
It is an important object of this invention, to. provide a mandrel whichv will satisfy the fore going requirements and which will be especially simple in construction and efficient in use. A further object of this invention is the provision of a novel mandrel adapted toengage and sup.- port a tubular core and to transmit thereto the driving force necessary to rotate the same.
Other objects. of this invention, together with certain details of construction and combina tions of parts, will be apparent. from the following detailed description and claims...
According to the present invention, 1711211131 1 drel is formed by mountingoneor more fittings on a shaft; The fittings employed comprise a tubular part having a groove extending circumferentially thereof and a sleeve of fluid-impermeable, elastic material carried by said tubular part in such a manner that the sleeve forms with the groove a passageway sealed from the atmosphere. The fittings are provided with means for introducing fluid under pressure into the passageway whereby, after a tubular core is positioned on the mandrel, the elastic sleeve may be expanded to come into contact with the interior of the tubular core, holding the latter firmly on the mandrel. To remove the tubular core from the mandrel, the fluid is caused to be ex- 5C1afms; (Cl. 2427-72) 2. hausted from the passageway, permitting the elastic. sleeve to contract and resume. its static position. out. of contact with the interior of the tubular core. The tubular core may then be. readily slipped ofi the mandrel.
A. preferred embodiment of this invention. is.
shown in: the accompanying drawing whereinz.
Fig... 1 isaside-elevational view, partly in; sec
tion, of a mandrel having a tubular core. mount-- ed thereon. and
Fig. 2 is a detail view, on an enlarged scale, andpartly in. section. of a. portion. of, the mandrel shown. in. Fig. 1.
Referring nowto the drawing, the reference,
' numeral H designates a tubular core... for suption. to each. other on. the shaft 14 by meansof. Each. of the. fittings comprises asst-screw l1... 7 a. tubular: part [8. provided between its; ends 19 and-.21 with. a. groove 22.. The end [9 is of larger diameter than the end 21,. but. is cutaway at. l3v to form a circumferential seat of the same diameter as the end 21.. impermeable, elastic material, such as rubber is, fitted onto the seat 23 and the end 21 and bridges, the groove 22 to form a passageway 25 sealed. from the atmosphere. An annular disc 26., having a diameter equal to. that of. the. endv I9. and slightly less than that of the tubular core. H. is fastened by means of bolts 2?: to the; end 2l. of tubular part. iii. The sleeve 24. is cemented to the end 2i and the seat 23, whose outer surfaces are roughened to improve the eihcacy of the cemented bond, and the sleeve 24 is held securely in place by means of a wrapping 28 of fine Wire. Communicating with the passageway 25 is a conduit 29 that extends through the end l9 and the seat 23 and is provided at its outer end with a valve 3!, which may be of the type employed in pneumatic tires. The fitting I5 is also provided with a ring 32 fastened to the end [9 with a set screw 33.
In use, a tubular core H is slide over the fittings l5 and I6, the ring 32 acting as a stop to position said tubular core properly on the man- A sleeve. 24 of fiuid.-.
drel l3. A fluid under pressure is then admitted into the passageway 25 of each of the fittings l5 and 16 through the valves 3| and the conduits 29, which fluid causes the sleeve 24 to expand into contact with the interior of the tubular core ll, engaging the same firmly as shown in Fig. 2 of the accompanying drawing. To release the tubular core I I, the fluid under pressure is exhausted from the passageway 25 of each of the fittings l5 and 16 through the conduits 29 and the valves 3 I, permitting the sleeves 24 to contract to the position shown in dotted lines in Fig. 2 of the accompanying drawing, 1. e. out of contact with said tubular core H, which may then be removed readily from the mandrel 13.
Instead of providing each of the fittings I5 and 15 with a valve 3 I, the passageways 25 insaid fittings may be operatively connected by suitable for introducing a fluid under pressure into said grooves whereby the sleeves may be expanded into contact with the tubular member, and stop means fastened to the outer end of one of said fittings to position said tubular member properly on said mandrel.
4. In a mandrel adapted to engage and support a tubular member, a shaft, and a fitting mounted on said shaft and comprising a tubular part having one end thereof of larger diameter than the other and having an annular disc fastened to the other end thereof, said larger end and said disc having a diameter slightly less than the inner diameter of the tubular member whereby the tubular member may be slid readily onto said mandrel, and said larger end having a seat whose diameter equals that of the smaller end, a groove extending circumferentially of the tubular part tubing, so that fluid under pressure may-be admitted to both of said passageways simultaneously through a single valve. While the mandrel I3 shown in the accompanying drawing has two fittings l5 and I6 for engaging the tubular core ll, any desired number of fittings may be employed for this purpose.
It is to be understood that the foregoing detailed description is given merely by way of illustration and that many variations may be made therein without departing from the spirit of our invention.
Having described our invention, what we desire to secure by Letters Patent is:
1. In a mandrel adapted to engage and support a tubular member, a shaft, a fitting mounted on said shaft, a groove extending circumferentially of said fitting, surfaces positioned on each side of said groove and extending circumferentially of said fitting, a sleeve of elastic material fastened to said surfaces and extending across said groove, and a conduit for introducing a fluid under pressure into said groove whereby the sleeve may be expanded into contact with the tubular member.
