IVEGLID FOB, CASTING VENT-PIPE FLASHINGS Specification of Letters Patent.
Patented Mar 4. i 919 Application filed November 4, 1918. Serial No. 260,997.
To all whom it may concern:
Be it known that l, JOHN H. Ross, a citizen oi the United States, residing at Kansas City, in the county of Jackson and State of lt'lissouri. have invented certain new and useful lniprovements in Molds for Casting Vent-Pipe .lilashing 's, of which the follow ing is a specification.
My invention relates to a mold for casting vent pipe fiashings in one piece, and my object is to provide a mold of this character wherein vent pipe flashings may be produced more quickly and econon'lically than heretofore.
' Heretoiore, it has been customary to form the tube and the flat sheet of vent pipe fiaslr ings separately and then solder or otherwise secure them together. Such procedure is expensive as it involves considerable time and labor and the product is not of uniform quality owing to defective or leaky joints being formed between the tubes and the fiat sheets.
' By the use of my mold the product is cast in one piece, preferably of lead, and comes out of the mold ready for use, thereby savv ing the old two-piece product together.
. faces 0 ing the time and expense required in plac- In order hat the inventionmay be fully understood, reference will now be made to the accompanying drawings, in which':'
Figure 1 is a front elevation partly broken away of the mold in locked position.
Fig. 2 is a broken side elevation of the mold in. locked position.
Fig. 3 is a vertical section on line IIL-IH of Fig. 1.
Fig. is a transverse section on line" IV IV of Fig. 1, with some of the parts removed.
l 5 a detail perspective of a core forming part of the mold.
Fig. 6 is a broken detail perspective of a v shaft and eccentrics associated therewith.
ln carrying. out the invention, it employ two main inen'ibers 1 and 2 reinforced by marginal flanges 4 and .5, and short intermediate flanges 3 and 6. respectively. The main nninber is also provided at its inner face with bottom and side flanges 7, which constitu the boundary for three sides of c space between the adjacent me: s l and 2. A. gate 11 at the upper end e main members 1 and 2, connnnnicates with. the space 9, so that the with cars 13 and 14;, respectively, at their lower ends to receive a pivot 16, so that said members 1 and 2 may be opened and closed. The opening movement of the members 18 limited by stops 18, which project from the ears 13 into the path of the lower transverse flange 5 on the main member 2.
22 designates a tubular protuberance extending backwardly and downwardly from the main member-land provided at its rear margin with an internal annular flangefls As disclosed by Fig. 3, said tubular protuberance 22 extends downwardly at an angle of about forty-five degreesfroin the member 1 to give the proporpitch to the tubular portion of the produet'cast in the mold.
26 designates the'tubular core which is adapted to extend throughthe tubular protuberance 22 and have its rear end fit snugly within the annular flange 24, so that the molten metal poured into'the mold can not escape between'said flange 24- and the core 26. The front end of the core 26 is providedwith an external" marginal flange 30, adapted to fit snugly'within an opening 31 in the mainmeinber 24 As disclosed by Fig.
3, the tubular protuberance 22, the core 26 and its flange 30Ftaper downwardly. This construction permitsthe core 26 and its flange 30to engage the flange 24 and the' surrounding wall of the openingBl, respectively, and thus limit the inward movement of the core 26. It also permits the core 26 to be readily released from the tubular por tlon of the casting and gives sufficient taper to said tubular portion to permit it to be readily withdrawn from the tubular space 33., between the interior of the tubular protuberance 22 and the exterior of the core 26.
35 designates a hand lever fixedly-mounted upon a shaft 36rochably-inounted in oppositely-disposed bearings 37 on the core flange 30.- Said shaft 36 is provided at its ends with fixedly-mounted eccentrics 39,carrying laterally extending ecoentricallymounted pins 40 operably-arranged in the slotted portions 41 of lugs 42, fixed to the longitudinal flanges 5 of the main member 2.
45 desi ates a hand crank fixedly-mounted upon a s aft 47 journaled in oppositeZy-dis' posed bearings 48 at the upper portion of the main member 2. The shaft 47 is pro vided at its ends with fixedly-mounted eccentrics 50, having eccentric pins 51 adapted to engage keepers 52' fixed to opposite sides of the main member'l.
53 designates a link pivotally-connected at its ends to the hand crank 45 and a crank 54, which latter is fixed upon a shaft 55 rock- 63 and 64 designate handles at the upper portions of the main members 1 and 2, respectively, whereby the same may be opeued and closed.
In practice, the mold is supported in up right position and the main members 1 and 2 are firmly locked together in closed position by swinging the hand crank 45 downwardly to the positiondisclosed by Fig. 3. As the hand crank 45 is swung downwardly, it, through the intermediacy of the interven ing parts, rocks the eccentric pins 51 and into engagement with the hook- shaped terminals 65 and 66 of thekeepers 52 and 62, respectively, and forces the flanges-7 of the main member 2 tightly against the inner face of the main member 1. The core 26 is then forced inwardly until its rear terminal and flange 30 are firmly seated in the flange 24, and the wall of the surrounding opening 31, respectively, in the main member 2. This is accomplished by raising the lever 35 to the position disclosed by Fig. 3. As the lever 35 moves upwardly, it through the intermediacy of the intervening parts, forces the eccentric pins 40 against the edges 70 of the slots 41, and forces the shaft 36 and the bearings 37 toward the main member '1 and thus firmly seats the core 26, as above described. As the core 26 moves inwardly its flange 31 is guided by the beveled ends 6 of the short flanges 6, so that it will be properly seated. The metal is then poured into the gate 11, where it is divided by the spreader 10, which causes it to flow down at opposite sides of the core26 and fi1l the lower portion of the space 9 before the tubular-space 33 and the upper portion of said space 9 are filled with metal. Thus a good casting free from blow-holes is assuredcient leverage is afforded to readily release the core 26 from. the casting as above described. The main member 2 is then imlocked from the main member 1 by swinging the hand crank 45 upwardly, which, through the intermediacy of the intervening parts, causes the eccentric pins 1 to rock into engagement with the edges 74 of the keepers 52, whereby sufficient leverage is obtained to pry the member 2 away from the member 1 and the casting. This operation also rocks the eccentric pins'60 out of engagement with the keepers 62, so that the lower portion of the member 2 is free t swing open. The handles 63 and 64 are then grasped and the main member 2 is swung 0 en far enough to permit ready removal o the castin from the member 1. From the foregolng description, it is parent that I have produced a mold wherein vent pipe flashings can be quickly cast in one piece, and while I have shown and described:
the preferred form of my invention, I re serve the right to make such changes in the construction, combination, and arrangement of parts as properly fall within the spirit and scope of the claims.
Having thus described my invention, what,
I claim and desire to secure by Letters Patcut, is:
