    Abstract: 11,619. Stewart, C. L. May 18. Exhaust-silencers. -The exhaust gases entering the chamber B pass through the aircooled tubes E and chamber C to the atmosphere through apertures F. When the silencer is used on motor-vehicles, the air entering the opening D has an ejector-like action and lessens the b a c pressure in the cylinders. The action may be increased by prolonging the mouth D or providing a fan. In a modification, the chambers B, C are arranged concentrically. A sliding or rotating sleeve G regulates the action. The tube D may end at the mouth of a larger tube which runs through the chamber C. This second tube may have a bell mouth. The tubes may be relatively adjustable.

    Abstract: 10,958. Stewart, C. E. June 16. Leaf-holders; reading-desks.-Pivoted to brackets 3 on a back piece 2, or desk, having a notch 7, is a rocking trough or angular sectioned support 1. When the book, music, &c. rests on the back flange 1 the front flange keeps it open,but, by depressing the front flange, the back flange rises, and the leaf can be readily turned.

    Abstract: An indirect extrusion process, and apparatus therefor, for producing an extrusion product from a hot metal billet. A press container is mounted to be substantially axially stationary during extrusion of a billet. A hot billet, a die and a pressure disc are located into the axial throughbore of the container so that the billet is sandwiched between the die and pressure disc, with the pressure disc having a maximum outer diameter between opposite radial faces which is slightly less than the diameter of the axial throughbore to define a diametrical clearance between the pressure disc and the press container. A bolster is located adjacent the pressure disc and is axially fixed to substantially prevent axial movement of the pressure disc in a direction toward the bolster during extrusion. The bolster exerts a relatively insigificant axial force against the container. An elongated stem having an axial passage is moved into the throughbore of the container to press the die toward the bolster, causing the billet to be extruded through the die to create an extrusion product which exits the container through the axial passage in the stem, while extrusion of the billet through the diametrical clearance between the pressure disc and the container is substantially avoided.

    Abstract: An apparatus for pre-piercing billets includes a generally cylindrical container for receiving and supporting a generally cylindrical billet, a mandrel bar mounted for axial movement along the axis of the cylinder for penetrating the billet, and a bolster for engaging the billet during penetration of the billet by the mandrel bar, wherein the bolster includes a bolster pin which is axially movable along the axis of the container, the bolster pin having an end which contacts the billet during penetration of the billet by the mandrel bar such that the billet deforms about the end of the bolster pin. A movable support is carried by the mandrel bar toward the billet during advancement of the mandrel bar prior to pre-piercing the billet, the movable support being configured to enter the generally cylindrical container to engage a portion of the container so as to provide additional structural rigidity to the mandrel bar to resist deflection of the mandrel bar during penetration of the billet.

    Abstract: An indirect extrusion press and method of operating the press. The press includes a container with opposite axial ends and an axial cavity for receiving a billet. The container is mounted for aligning the axial cavity with the extrusion axis. A bolster is disposed adjacent one axial end of the container for blocking movement of a billet out of the cavity when a force is applied against the billet from the other axial end of the container. A ram is mounted on the side of the container adjacent the other axial end of the container for movement in the axial direction of the container. The ram has an axial passage therethrough aligned with the extrusion axis. A rotatable turret is mounted on the ram, and a hollow pressing stem is mounted on the turret. The turret is rotatable for placing the hollow pressing stem in a first position aligned with the extrusion axis, and in a second position off of the extrusion axis. When the hollow pressing stem is in the first position it communicates with the axial passage through the ram and can be moved axially, via the ram, to press a die through the cavity to extrude a billet to form an extrusion product which exits the container via the hollow pressing stem and the axial passage in the ram. When the hollow pressing stem is in the second position it permits other tooling to perform operations on the extrusion axis of the press.
