摘要： Method and apparatus for providing inserts, such as lift inserts and step inserts, in cast members. The inserts have breakaway tabs mounted in receiving slots in either a reusable holder or disk-shaped member. The assembled insert and holder are inserted through a collar on the outer jacket of a mold assembly and a locking pin passes through cooperating openings in the holder and collar to retain the lift insert/holder in place during the casting operation. The disk-shaped member is fixed to a jacket of the mold assembly. The breakaway tabs break away from the insert when the cast member is separated from the mold assembly, the breakaway tabs being discarded and the holder (disk-shaped member) being reusable many times for subsequent casting operations. The slots, in one embodiment, have a locking shoulder to lock the tabs in their slots. In another embodiment, a cam surface on the tabs lock the tabs in the slots. In another embodiment, one slot and one tab differ in radial or circumferential length from the other tabs and slots to permit alignment between the slots and tabs in only one position to assure that the tabs are properly mounted in the holder.

摘要： An annular-shaped, expansion type clamping band has laterally overlapping ends, each having a skewed surface, the skewed surfaces slidably engaging one another. The ends are further provided with elongated guide slots for receiving a threaded bolt. A threaded nut threadly engaging the bolt, when tightened, moves the overlapping ends toward a longitudinal central axis of the band whereby the band expands to exert an outward radial force against an interior surface of a gasket to provide a liquid-tight fit between the gasket and an opening having a surface engaging an outer periphery of the gasket. The band may be a one-piece or two-or-three-piece assembly and may be formed of an suitable metallic or plastic material. The threaded member is slidable along the aforesaid guide slots enabling the bolts to be self-centered. The nut and bolt assembly, in one embodiment is designed to require only one tightening tool.

摘要： A placement ring assembly has inside and outside mandrels releasably fastened together to secure and align a pipe connector gasket therebetween. A permanent magnet of a magnet assembly is inserted through co-aligned openings in the mandrels and is magnetically attracted to an inner-core of a casting assembly. When the cast member is set, a mechanical release is rotated to release the magnetic attraction between the permanent magnet and the mold core. One of the mandrels may be provided with shock absorbing knockout pads while the other mandrel has openings aligned with the knockout pads to enable the knockout pads to be struck with a hammer to separate the mandrels. Rubber cushioning members absorb the shock of the impacts, protecting the mandrel from permanent damage. One-piece hole formers may likewise be provided with a magnetic assembly having a mechanic release as well as knock-out pads.

摘要： Method and apparatus for forming cast members. Steps are provided in the cast member by sliding mounting flanges of hollow plastic step inserts into slots provided in the inner mold shell. The cast material is then poured into the mold. Once the cast material has set, the cast member is withdrawn from the mold assembly. The step insert mounting flanges are broken away, leaving hollow step inserts into which manhole steps are force-fittingly mounted. The inserts are provided with integral cover tabs which cover larger slots provided to facilitate insertion of the step inserts, preventing leakage of the cast material into the mold assembly. Integral cover tabs are similarly provided on enforcement ring support members mounted in a similar fashion to insertion slots provided on one of the mold members to cover larger width slot portions to prevent seepage of cast material. Similar seals are provided by cylindrical-shaped inserts for use in wetcast and drycast fabrication methods.

摘要： A resilient compressible gasket having an embedment portion, a pipe engaging portion and a intermediate “radius” portion integral with the embedment and pipe engaging portions. The gasket assumes a “pleated” configuration when in the operative position, the pipe engaging portion extending through the embedment portion, yielding a gasket which compensates for deviation of the pipe from a nominal horizontal alignment without any reduction in the water-tight seal provided by the gasket. The gasket is sized to provide for easy insertion of a corrugated pipe into the pipe engaging portion while providing an excellent water-tight seal when clamped into position about one or more annular recesses and peaks of the corrugated pipe. Another embodiment of the gasket is designed to be secured to a cored or performed opening in a cast member through the use of an expansion-type clamping assembly. The free end of the pipe engaging portion is preferably provided with a radially outwardly directed flange which greatly facilitates alignment of the pipe engaging portion with an annular recess (or an annular peak) of a corrugated pipe.
摘要翻译：一种弹性可压缩垫圈，具有嵌入部分，管接合部分和与嵌入和接合部分成一体的中间“半径”部分。当处于操作位置时，垫圈呈现“褶皱”的结构，管接合部分延伸穿过嵌入部分，产生一个衬垫，其补偿管道与公称水平对准的偏差，而不会由垫圈。垫圈的尺寸设计成能够容易地将波纹管插入到管接合部分中，同时当夹紧在波纹管的一个或多个环形凹部和峰部的位置时提供优异的防水密封。垫圈的另一实施例被设计成通过使用膨胀型夹紧组件固定在铸件中的芯或执行开口。管接合部分的自由端优选地设置有径向向外的凸缘，其极大地便于管接合部分与波纹管的环形凹部（或环形峰）对准。

摘要： A bidirectional gasket providing a water-tight seal between a manhole assembly and a pipe, having a T-shaped anchoring portion for embedment in a manhole opening. An A-shaped pipe engagement portion joined to the anchoring portion by a connecting web facilitates bending of the gasket. The A-shaped portion has "legs" and recesses forming water pockets preventing water from entering between gasket and pipe. The gasket durometer enhances the water tight seal of the legs with increasing water pressure. The pipe engaging portion accommodates a greater outside pipe diameter compared with conventional connectors due to reduced volume, by providing voids within the connector. The gasket accommodates diameter deflection or ovation in rigid and flexible pipe materials. The A-shaped profile provides greater angular deflection and/or pipe misalignment allowance compared with conventional connectors. Tapered projections near the apex wipe the pipe external periphery upon insertion and further contribute to compression of the connector in the nose portion, preventing the projection from flipping over during pipe insertion. The web joining the anchoring and pipe engagement portions has a tapered cross section, increasing in thickness toward the pipe engagement portion, enhancing compression of the web against the pipe. The connecting web and interior periphery of the T-shaped portion have integral projections which eliminate profile thinning and significantly reduce water infiltration. The simplified water pocket recesses ease installation problems and prevent pull-in of the water pocket which results in connector failure.

摘要： A bidirectional gasket providing a water-tight seal between an opening in a manhole assembly and a pipe extending into said opening, comprises a T-shaped anchoring portion for embodiment in a manhole opening. A substantially A-shaped pipe engagement portion is joined to the anchoring portion by a slender connecting web facilitating bending of the gasket. The A-shaped portion has "legs" and recesses which form water pockets preventing water from entering. The durometer of the gasket material enhances the water-tight seal of the legs with increasing water pressure. The pipe engaging portion accommodates a greater outside pipe diameter compared with conventional connectors due to reduced volume, by providing voids within the connector together and a lower durometer of gasket material. The gasket has enhanced ability to accommodate diameter deflection or ovation in rigid and flexible pipe materials. The A-shaped profile allows for greater angular deflection and/or pipe misalignment compared with conventional connectors. The gasket apex has a recess to locate the voids which, in addition to enhancing mechanical softness of the gasket, also provides the ability to increase gasket compression by introducing a liquid filler into the voids. Tapered projections near the apex wipe the external periphery of a pipe upon insertion and also contribute to the compression of the nose portion of the connector. The gasket may be molded or formed from an elongated extrusion joined at its ends to form an annular gasket.
摘要翻译：在井孔组件中的开口和延伸到所述开口中的管道之间提供水密封的双向垫圈包括在人孔开口中用于实施例的T形锚固部分。基本上A形的管接合部分通过细长的连接腹板连接到锚固部分，有助于垫圈的弯曲。 A形部分具有形成防止水进入的水袋的“腿”和凹槽。衬垫材料的硬度可以增加水的压力，增加腿的防水密封。通过在连接器内提供空隙和垫圈材料的较低硬度，管接合部分由于体积减小而容纳与常规连接器相比更大的外管直径。垫片具有增强的刚性和柔性管材料中适应直径偏转或鼓动的能力。与常规连接器相比，A形轮廓允许更大的角度偏转和/或管未对准。垫圈顶点具有凹部以定位空隙，除了增强垫圈的机械柔软性之外，还提供通过将液体填充剂引入空隙中来增加垫片压缩的能力。在顶点附近的锥形突起在插入时擦拭管的外周，并且还有助于连接器的鼻部的压缩。垫圈可以由在其端部处连接的细长挤出件成型或形成以形成环形垫圈。
