摘要： A lathe assembly having a guide with a passageway for movement of a piece of bar stock, with a leading end and a trailing end, in a substantially straight path between a feeding position and a working position. A sensor assembly is capable of detecting the position of the trailing end of a piece of bar stock within the guide passageway to thereby allow a user to determine if a piece of bar stock in the guide passageway has a length sufficient to perform the desired operation thereon. Also, a method of using the lathe assembly.

摘要： A device for withdrawing from a bar pusher and thereafter unloading the crop-ends of metal bars in a bar feeding apparatus for a multi-spindle lathe, the device being suitable also for placing a new bar on the bar pusher, is disclosed; the device of the invention is comprised essentially of a pair of movable jaws which by a turning movement close onto the crop-end of a metal bar and lock the crop-end therebetween; the crop-end is the residual part of the lathe machining of the metal bar; thereafter the jaws accomplish a translation movement to detach the crop-end from a bar pusher which formerly caused the bar forwarding in the feeding apparatus of the lathe; the jaws thereafter open slowly dropping the crop-end in a proper unloading zone; finally the jaws close onto a new metal bar to be machined and, by a further translation movement in the direction opposite to the former one, perform the insertion of the new metal bar end into the bar pusher.

摘要： The particular machine described has a series of main collets mounted in an indexable drum, each main collet having an associated reciprocable feed tube carrying at its rear end a one-way feed collet employing wedging elements in the form of spring-loaded balls carried in inclined bores of the feed collet body, the feed tubes and feed collets being indexed with the main collets and with a reel-type bar holder. When the collets are arranged to feed non-round bar stock each feed collet is keyed to its associated main collet to enable non-rotating bar stock to be introduced into a rotating feed collet from the bar holder, to be rotated by the feed collet, and then fed through the main collet without stopping the main collet. An axially movable and retractable stop is provided at the feeding station to ensure that an adequate length of bar stock is gripped by a main collet during subsequent machining. Each feed collet is formed in two parts which are capable of axial movement apart against spring-biassing to accommodate the axial movement of the stop at the feed station. At the station preceding the feed station an attempt is made to move the feed collet there towards its associated main collet which is in its closed condition. If a bar is present then movement of the feed collet will not be permitted, but if movement is allowed due to the absence of a bar this is indicated to the machine operator so that the operator can load a new bar into that feed collet. All of the machine mechanisms associated with feeding bar stock are drived from the principal prime mover of the machine. It is unnecessary to provide an automatic mechanism for feeding the bar-loader.
摘要翻译：所描述的特定机器具有安装在可转位滚筒中的一系列主夹头，每个主夹头具有相关联的可往复运动的进给管，其后端承载单向进给夹头，所述单向进给夹头采用倾斜运载的弹簧加载球形式的楔形元件进给夹头体的孔，进料管和进料夹头用主夹头和带盘式条夹固定。当夹头布置成进给非圆形棒料时，每个进给夹头被键入到其相关联的主夹头，以使非旋转棒料从杆保持器引入到旋转进给筒夹中，由进给夹头旋转，然后通过主夹头进给，而不停止主夹头。在进给站处设置有可轴向移动和可缩回的止动件，以确保在后续加工期间由主夹头夹持足够长度的棒料。每个进给夹头形成为两部分，其能够轴向移动以抵抗弹簧偏压以适应止动件在进给台处的轴向运动。在进料站前的站，试图将进给夹头移动到其关闭状态下的相关联的主夹头。如果存在条，则不允许进给夹头的移动，但是如果由于没有杆而允许移动，则向机器操作者指示，以便操作者可以将新的条装载到该进给夹头中。与进料棒料相关联的所有机器机构都从机器的主要原动机驱动。不需要提供用于进给条形装载机的自动机构。

摘要： A bar feeder includes an elongated rectangular box having an open top. An elongated trough is mounted on the top of the box. A bar push rod is slidably positioned in the trough. Drive means is mounted within the box for moving the push rod along the trough. A feed device feeds elongated cylindrical bars into the trough ahead of the push rod. The push rod forces the bars along the trough into another machine. The drive means is a variable speed, limited torque eddy current clutch.
