MOLDING APPARATUS FQR THE MANUFACTURE OF PIPE.
SPECIFICATION formingpart of Letters Patent No. 278,6,63, dated May 29, 1883.
Application filed April 9, 1883, (No model.) I
To all whom it may concern Be it known that we, WILLIAM IRETON and SAMUEL E. WHITELOCK, of the city of amden, county of Camden, State of New Jersey, it
have invented anImprovement', in Molding Apparatus for the Manufacture of Pipe, of which the following is a specification.
Our invention has reference to molding apparatus, but particularly to an improvement on Letters Patent granted to William lrcton, March 13, 1883, and No. 273,738; and it consists of the cam-shapedformer therein shown provided with an adjustable device by which the thickness of the metal pipe tobe cast may be varied without changing the former and, further, in a suitable construction of support for the bottom, of said former, whereby the (mouth of the pipe-mold may be packed ina manner similar to the body of thejpipe, and in details of construction, as fullyset forth in the followingspecification and shownin the accompanyiu g drawings, which form partthereof.
rious diameters without changing the former,
means tosupportthe sand in the flask after the former of the molding apparatus has been,
The object of our invention is to provide a molding apparatusof this kind with means whereby the former may make the mold of vaas a whole, to give different weights of pipe when cast by varying thetthickness of metal;
and,'fnrther, to provide means to pack the sand in the flask to form the enlarged part or mouth of the pipamold, and also to provide removed therefrom and the flask is raised from l and 1).
its support and placed inthe casting-pit. In the drawings, Figure 1 is a sectional elevation of our improved pipe-molding apparatus. Fig. 2 is a cross-section of same on line a0 a2, and Fig. 3 is a cross-section on line y y.
A is the former, which is provided with the straight or spiral cam-groove A, as fully set out in the patent hereinbefore referred to.
The bottom is reduced in diameter, and is'proevident, also, that 'by "arying the diameter of when cast, will be more orless, and if the core the sleeve B the external diameter of the pipe,
is uniform the metal in the pipe must vary.
This is important, as in some class of work set forth in the previous patent referred to, having the hopper I at the top, as well as bearing for the former A. At the bottom itis made somewhat bell-mouthed, and provided with a flange, H, to which is secured the ahnnlar plate G by bolts g or other equivalent means; or the'plate G may be cast with said flask. This flask and plate then rest upon and may be temporarily bolted or clamped to the support F, having recessed aperture f,
preferably provided with beveled centering-- walls e 0.
Supported in the recesses of plate'F is the head 1),,having the annular part D, which is provided with the cam-groove E, which forms a continuous groove with A of the former, the said part D, when rotated, molding the outer surface of the bell-mouthed end of the pipe-flask, its interior fitting snugly against the sleeve 13, and to which it acts as a hearing. The center D of headD projects up into the space 0 of the former A, is preferably madeconical on the top, as at 61 and has grooves d, into which the former-lugs c fit, to the end that when the former is rotated the head will rotate also. An annular space is formed between the central part, D and annular flange part D, into which the bottom of the former fits, as shown, and to preventcloggin'g by sand apertures d are made, through the bottom, through which any sandmay be brushed,
The operatiouis as follows: The head D being placed in the supportF and the flask H secured thereon, the former is put in position and sand is admitted and placedaround the same by hopper I and apertures at the top..
Now, as the former and head are rotated the sand is admitted by groove i and is packed solid, and when completed the former is raisedwhile being rotated, the ring or sleeve smoothing up the interior of the mold. When the former is removed the flask is taken away to receive its core and placed in the castingpit, and the head D remains in the support, ready for another flask.
We do not limit ourselves t( the construction shown, as it maybe modified in various "ways without departing from our invention.
Having now described our invention, What we claim as new, and desire to secure by Letters Patent, is-- 1. In apparatus for molding pipe, 850., a stationary flask, in combination with a rotating former supported against lateral pressure in said flask, adapted during its revolutions to compress the sand within said flask into the requisite shape, and atrotating molding-head to form the mold for the bell-mouthed end of the pipe, substantially as and for the purpose specified.
2. In molding apparatus, a stationary flask, in combination with a cylindrical former supported, in said flask, arranged to rotate within said flask, having its surface made cam shape, and a rotating molding-head to form the mold for the bell-mouthed end of the pipe, substantially as and forthe purpose specified.
3. In amolding apparatus, astationary flask, in combination with a former arranged to rotate within said flask, supported atthe bottom by rotating molding-head arranged to rotate in the bottom of theflask,the said former having a longitudinal cam-groove arranged upon its surface, substantially as and for the purpose specified.
4. In a. molding-apparatus,a stationary flask, in combination with a. former arranged to rotate within said flask, supported atthe bottom by rotating molding-head arranged to rotate in the bottom of the flask,the said former and head ha7ing longitudinal cam grooves arranged upon their surfaces, substantially as and for the purpose specified.
5. In molding apparatus, a stationary flask, in combination with a former supported in hearings in said' flask, arranged to rotate within said flask, having a spirally-arranged cam-groove about its surface, and a rotating molding-head to form the mold for the bellmouthed end of the pipe, substantially as and for the purpose specified.
vsupports for the former, both at top and bottom, in combination with 'a rotating former provided with corresponding bearings, having its surface made cam-shaped, being provided in its upper hearingwith a feed groove or slot to admitsand to the interior of the flask during the operation of packing, and a rotating molding-head to form the mold for the bellmouthed end of the pipe, having a cam-groove therein to compress the sand, substantiallyas and for the purpose specified.
- 8. In apparatus for molding pipe, 850., a stationary flask, incombination with a rotating former supported against lateral pressure in said flask, adapted during its revolutions to compress the sandwithin said flask into the requisite shape, and a removable smoothingband arranged about the bottom of said former, substantially as and for the purpose speci- 9. In apparatus for molding pipe, &c., a stationary flask, in combination with a rotating former supported against lateral pressure in said flask, adapted during its revolutions to compress the sand within said flask into the requisite shape, a rotating molding-head to form the mold for the bell-mouthed end of the pipe, and a removable smoothing-band arranged about the bottom of said former, substantially as and for the purpose specified.
10. In apparatus for molding pipe, &c., astationary flask, in combination with a rotating former supported against lateral pressure in said flask, adapted during its revolutions to compress the sand within said flask into the requisite shape, and a plate, Gr, substantially as and for the purpose specified.
11. In apparatus for molding pipe, 850., astationary flask, in combination with a rotating former supported against lateral pressure in compress the sand within said flask into the requisite shape, a rotating molding-head to form the mold for the bell-mouthed end of the pipe, and a platc, G, substantially as and for the purpose specified.
12. The combination of flask H, former A, having cam-groove A, head D, plate G, and support F, substantially as and for the purpose specified.
13. The combination of flask H, former A, having cam-groove A, having band or sleeve B, head D, plate G, and support F, substantially as and. for the purpose specified.
14.. The combination of flask H, former A, having cam-groove A, and having band B and head D, substantially as and for the purpose specified.
In testimony of which invention we hereunto set our hands.
