摘要： Formed steel channel members mounted horizontally on vertical rods to the back of a drafting reference table. Two channel members are vertically adjustable to allow drawings, layouts and the like of different dimensions to be conveniently located and supported, and a third channel member serves to prevent material from slipping off the back of the table.

摘要： An arm of a tractor-mounted loader is coupled to the top of a loader mast having a bottom end received in a pocket formed at an outboard area of a horizontal base plate of a loader mounting frame connected to one side of the tractor. A quick coupler support bracket is mounted to the base plate inboard of the pocket. Supported by and projecting upwardly from a horizontal fitting mounting plate of the support bracket are respective quick coupler halves forming ends of a first set of hoses that are coupled to the tractor hydraulic system. The first set of hoses extend through a hose passage, provided in a rear wall of a walled structure joined to and cooperating with the base plate so as to form a cavity therebeneath, and through a set of fitting openings provided in the fitting mounting plate. A second set of hoses extend from the rear of the arm and has a second set of quick coupler halves connected to the first set of quick coupler halves.

摘要翻译： 拖拉机装载机的臂结合到装载机桅杆的顶部，该装载机桅杆的顶端容纳在形成在连接到拖拉机一侧的装载机安装框架的水平基板的外侧区域中的凹穴中。 快速联接器支撑托架安装在口袋内的底板上。 从支撑托架的水平安装安装板向上支撑并向上突出的相应的快速联接器半部分形成连接到拖拉机液压系统的第一组软管的端部。 第一组软管延伸通过软管通道，该软管通道设置在与基板接合并与基板配合的壁结构的后壁中，以形成其下方的空腔，并且通过设置在配件安装板中的一组配合开口。 第二组软管从臂的后部延伸并且具有连接到第一组快速耦合器半部的第二组快速耦合器半部。

摘要： Guard structure for the forward portion of a rotary cutter including a front sill with a formed angle section that is permanently attached to the cutter to provide both protection from the rotary blade and structure for hanging chain links across the width of the front opening to restrict material from being thrown from the front of the cutter. In addition, the angle section strengthens the forward portion of the cutter.

摘要： A material handling implement includes side and wall panels composed of an impact resistant structure having low frictional resistance to the sliding movement of material therefrom. The panels are resistant to the organic acids and salts commonly found in manure and incur minimal moisture buildup on their surfaces. The preferred embodiment of the panel includes a plywood sheet encased within and bonded to fiberglass reinforced polyester sheets.

摘要： A hydraulically operated conveying mechanism for a manure spreader composed of a fore-and-aft shiftable floor extension that is supported on a fixed floor of the spreader box and a transverse vertical push-off supported to shift fore-and-aft on the extension. First and second hydraulic cylinders are used to shift the floor extension and push-off respectively and includes a first cylinder and associated rod with the latter being composed of inner and outer concentric tubes closed at their respective ends and with the inner tube opening into the closed end of the cylinder. The outer tube has a port opening into the cylinder. The second double-acting cylinder that operates the push-off has its opposite ends in fluid communication with the inner tube and outer tubes. A shuttle valve within the main cylinder shifts axially to close the port as fluid is introduced to the closed end of the main cylinder and opens the port as the rod approaches its fully extended position.
