PIPE-MOLDING APPARATUS.
SPECIFICATION' forming part of Letters Patent No. 359,269, dated March l5, 1887.
' Application filed January 29, 1886. Serial No.v 190,144. (No model.)
To @ZZ whom t may concern.-
Be it known that we, ANDREW H. MONRAY. and WILLIAM A. STINERUCK, both of Burlington, in the county of Burlington and State of New Jersey, haveinvcnted a new and valuable Improvementin Pipe-Molding Machines; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings,.mak ing a part of this specification, and to the letters and figures of reference marked thereon.
Figure l is an elevation, partly sectional, of a machine for operating the former of a pipe-molding apparatus embodying our inr provenients, the clutch mechanism, with operating-lever for the winding-drum, being removed. Fig. 2 is a perspective of a detail part of the machine. Fig. 3 is a horizontal section of same and part of the main or vertical frame of the machine. Fig. 4 is a transverse section, drawn to an enlarged scale, showing more plainly the clutch and the brake mechanism for the winding-drum; and Fig. 5 is a section on line 1 l, Fig. il.
Our invention has relation t0 molding apparatus for the manufacture of pipe, of the form wherein a former having a pressing-face on its periphery and rotated within the flask is rotated to compress the sand Within the requisite form for receiving the core; and it has for its object to provide power mechanism for rotating the former and for raising it out of and lowering it into thc flask, and suitable guides to keep it in position While it is raised or lowered.
Our invention accordingly consists of the combination, construction, and arrangement of parts, as hereinafter described and claimed.
In the drawings, A represents the upper part of a stationary fiask, and B the former constructed and arranged with a pressing face or faces on its periphery; or it may be otherwise constructed, as desired, as we do not limit our improvements to any particular kind of pipe-molding apparatus.
C indicates the power mechanism, composed, essentially, of an upright frame, D, of any suitable kind, having, if desired, a step or other bearing, d, and an upper bearing, d, so that it can be rotated around or about a circular row of flasks, or serve as a crane.
Upon one side of frame D, near its bottom, is suitably affixed a bracket, L, having at its outer end a bearing, Z, for the former B, and H upon the opposite side of said frame is a dog, Z', with operating-lever Z, for engagement with openings d'Z in the step-bearingcl, to lock the frame or crane D in a fixed position. Within the bearingl, preferably at its bottom, is a circular or other brush or rubber, m, for cleaning the former B as it is raised and lowered from and into the flask A. however, the brush m may be otherwise suitably placed in relation to former B.
Above the bracket L is a vertically-sliding frame, g, adapted to guides h, secured to or forming part of the frame D, (see more plainly Figs. 2 and 3,) and on the outer end of 4frame gis a bearing or support, g2, for the upper end of the former B, and at or near the middle of the frame g is a sheave or pulley, h3. The former B is connected, as shown, or otherwise, as dcsired, t0 a shaft or rod, l); or said `former and shaft may be integral, to rotate together, and be raised or lowered when necessary.
rIhe rod b has an upper bearing in a jib, platform, or bracket, C', and is provided at its upper end with a bevel-wheel, t', which is in gear with another like wheel, fi', upon a counter-shaft, I, suitably mounted in bearings affixed to bracket C', and shaft I in turn is in gear, by means of a bevel-wheel, li, with a like wheel, i4, splined upon a shaft, E, having a friction or other clutch mechanism, K, provided with operatinglever k, suitably pivoted to the frame D. r
The shaft E is the driving-shaft for the Inachine, and has at its upper end a bevel-wheel, e, meshing with a like wheel upon shaft F, from which power is transmitted to shaft E. It has at any suitable point below clutch K a bevel wheel, e', which meshes with a like wheel, h4, upon a counter-shaft, h5, provided with a gear-wheel, 7L, which meshes with a like wheel, hi, upon a shaft ofa winding-drum, II. The drum is more plainly shown in Figs. 4: and 5. It is loose on said shaft, and is provided with any suitable form of spring or other brake-band, 11,8. In the drawings one end of the latter is secured to one extremity of a lever, 7L, and the other to the frame D.
The drum H is preferably formed at one end with an enlarged head, around the outside or Iii desi red,
ICO
rotation of the former B in the mold.
periphery of which the brake-band hs is ap1 plied to brake or stop the drum, as hereinafter described. Vithin said drum-head is arranged a suitable form of clutch having operating mechanism for engaging the drum with its shaft and disengaging the same.
In Figs. 4 and 5 a form of clutch is shown having shoes a a connected by a right-and-left screw, n', provided with a gear wheel, n2, which engages with a rack-bar, n3, sliding in an axial opening in the drum-shaft, at one end ofthe same, and which has a swivelconnection, at, with an operating-lever, a5, suitably pivoted to the frame D, or a fixturethereon. By suitably moving the lever a5 the clutch shoes n n are thrown into engagement with and disengaged from the drum H or its head, to either clutch the drum with its sliaft,so that they will rotate together,or unclutch itfrom its shaft, so that the latter rotates independently of the drum, the brake-shoes n n being secured to and rotating with said shaft.
From the winding-drum H a rope or chain, h1", is conducted over a pulley, l1, having its bearings near the u pper part of frame D, thence under and over pulleys ltl, respectively, journaled in bracket C', then down and around sheave h3 on sliding bracket g, and thence upwardly to and secured on a hook, c, or other lixture on the bracket C, so that when the drum H is by its clutch mechanism thrown into engagement with the shaft E the drum is revolved and winds up the cord ,or chain hw to elevate bracket g and raise the former B from the flask A; and when the clutch mechanism is released from the drum it is free or loose upon its shaft, and the gravity of the bracket g and the former B then acts to unwind the chain or rope hw from the drum to effect an automatic descent of the bracket g and the former B toward flask A, the rate of speed of the descent of former B as it enters the fiask being regulated as desired by manipulating the brake ifS of the drum H.
The operation of the machine as a whole is substantially as follows: When the flask A is ready for the former B, the clutch mechanism for the drum H is released and the former B is free to descend into the iiask. The clutch K is then applied to engage the shaft E with countershatt I, for rotating the former B within the flask. By gradually applying the pressure to the clutch K power is correspondingly applied or communicated t0 the former B,to causeit to rotate evenly at a varying speed in proportion to that of the driving-shaft E.
When the mold in the flask is fully formed, the clutch K is released, and the shaft E is thrown out of gear with the shaft I to stop the The clutch mechanism of the drum H is then applied to cause it to Wind up the rope or chain h1 to raise the former B from the mold. The
bracket g being also raised, it serves to maintain the former in due alignment with the center line of the mold as the ascent is made, and
thereby preserve the configuration or pattern in the mold.
"What we claim is- 1. The combination of the frame D, having the bearing C, sliding bracket g2, bracket L, having bearing Z, rod b, former B, and actuating devices for rotating the rod b and former B and for raising and lowering the bracket g and said former, substantially as set forth.
