摘要： A snowmobile jack is described herein that raises the rear of the snowmobile off of the ground when it is not in use. Manufacturers suggest that snowmobiles be raised when not in use, so that their tracks do not freeze to the ground. Manufacturers also recommend that snowmobiles be warmed up with their tracks elevated. This cuts down on general wear and tear of the tracks and supporting belts. The jack comprises a vertical lift bar slidable within a sleeve. The bar is raised by a foot pedal lever which acts on the lower end of the bar and is latched in the raised position. The bar carries a transverse rod adjustable in height relative thereto with hooks for engaging the rear bumper of the snowmobile.
摘要翻译：本文描述了一种雪地车千斤顶，其在不使用时将雪地车的后部从地面提升。制造商建议在不使用雪地车时，不要将雪轨冻结在地面上。制造商还建议，雪地摩托车的高架轨迹会升温。这减少了轨道和支撑带的一般磨损和撕裂。千斤顶包括可在套筒内滑动的垂直提升杆。该杆由一个作用在杆下端并被锁定在升高位置的脚踏杠杆升高。该杆带有相对于其高度可调节的横杆，其具有用于接合雪地车的后保险杠的钩。

摘要： The sweeping brush of the machine is composed of two or more parts in order to maintain a constant pressure of the sweeping brush against the ground, to achieve faster clearance of the snow, and to avoid downtime for adjustments. These brush parts are swivellable relative to one another in a vertical plane. The common raising and lowering movement of the individual parts is controlled by a cylinder-piston unit, and the piston acting upon the brush parts is always impinged upon by a pressure opposite to the direction of movement. The individual brush parts may be connected to one another by torsion bars.

摘要： A clearing blade, as an attachment for a garden tractor or the like, is constructed as a double-walled construction thereby forming a box-like spreading funnel (5) between the wall members so that simultaneously with or after clearing snow, salt or other granular material may be spread by the same implement used for the clearing. Due to the rigid box-structure of the blade a sufficient strength is obtained even by materials of lesser strength than expensive, fracture resistant steels. Hence, such materials of lesser strength, e.g., synthetic materials, may be used for manufacturing the present blade by an injection molding or die-casting method.
摘要翻译：作为花园拖拉机等的附件的清理叶片被构造为双壁结构，从而在壁构件之间形成盒状扩散漏斗（5），从而在清除雪，盐或其它物体后同时或之后粒状材料可能被用于清除的相同工具传播。由于刀片的刚性箱体结构，即使是具有比昂贵的抗断裂钢的强度低的材料也能获得足够的强度。因此，这种具有较小强度的材料，例如合成材料，可用于通过注塑或压铸方法制造本发明的刀片。

摘要： An improved snowthrower (2) comprises a housing (4) having a rotatable impeller (6) therein. Impeller (6) is rotationally molded from plastic and is easily replaceable in housing (4). Moreover, impeller (6) includes a plurality of snow impelling blades (60) which are sufficiently rigid to transmit a drive torque from one side wall (63) to the other side wall (62) of impeller (6). Thus, impeller (6) does not require the use of a through shaft. In addition, snowthrower (2) includes a switch (93) for actuating the drive motor (8). Switch bar (96) is movable to cause switch (93) to close. However, lockout member (110) can be positioned in engagement with switch bar (96) to prevent inadvertent or accidental actuation of switch (93). Lockout member (100) is moved to a non-locking position only when a key member (116) is inserted into a control grip (112).
摘要翻译：一种改进的积雪车（2）包括其中具有可旋转叶轮（6）的壳体（4）。叶轮（6）由塑料旋转模制，并且容易在壳体（4）中更换。此外，叶轮（6）包括足够刚性以将驱动扭矩从一个侧壁（63）传递到叶轮（6）的另一侧壁（62）的多个积雪叶片（60）。因此，叶轮（6）不需要使用通轴。此外，积雪车（2）包括用于致动驱动马达（8）的开关（93）。开关杆（96）可移动以使开关（93）关闭。然而，锁定构件（110）可以定位成与开关杆（96）接合，以防止开关（93）的意外或意外致动。只有当键构件（116）插入控制把手（112）中时，锁定构件（100）才能移动到非锁定位置。

摘要： A method of removing snow by utilizing a conveyor unit configured to facilitate depositing of snow into a sewer system. The conveyor unit is fit on or within the manhole sewer openings from which the covers have been removed. The conveyor units comprise powered augers mounted within a snow receiving housing having hoppers from which snow is conveyed into the manhole openings. In a first version, the conveyor housing is directly received over the manhole opening, while in a second version, the hopper is offset from the manhole opening and snow is conveyed into the sewer system via a conduit extending from the hopper and into the manhole opening.

摘要： A variable width tool attachment for use with a vehicle is herein described as generally comprising a complete tool which is split vertically and in the direction of vehicle travel to form two half tools. The two half tools are slidably mounted for mutual relative movement in the direction normal to the direction of vehicle travel, i.e, in the direction of tool width. A hydraulic ram cylinder or the like is operable to move the two half tools to form the desired width.In one form of the invention, a horizontal cutting header is provided with a chain cutter and a chain drive having at least one moveable idler sprocket to take-up and let-out chain in the width direction whenever the width of the tool is varied.

摘要： A portable rotary snow thrower is disclosed. The housing of the snow thrower is baffled to cause the snow to be thrown to one side for a particular direction of rotation of the rotor. The rotor may also be rotated in the opposite direction to throw the snow to the opposite side of the snow thrower through the same opening without repositioning of baffles or other mechanical elements.

摘要： A tracked snowplow particularly suited for use in very deep snow. A frame is carried on a tracked mover. The frame supports a triangular belt which is made up of a number of chains, stretched about rolls, and a large number of shovels which extend perpendicular to the chains. The shovels engage the links of the tracked mover as the shovels move along their lower run. The upper run of the shovels is angled rearwardly, and so as the snow is carried by the upper run, the weight of the snow helps drive the shovels, and the shovels, engaging the tracked mover, help drive it. From the upper run the snow is deposited into two secondary carrying belts which convey it to the sides of the snowplow for throwing out.

摘要： A manually operable mobile snow plough includes a streamlined main body supported upon wheels or runners for movement over the ground or snow. The main body has one or more entrance openings for receiving snow, and at least one blade mounted rotatably within such openings. A snow discharge pipe is rotatably carried by the snow plough body and is provided with a vertically extending discharge slot. A snow guide member is pivotably mounted atop the discharge pipe, and an adjusting lever is included to permit setting of the discharge pipe in any one of a series of selected azimuthal positions.

摘要： A compact, lightweight snow thrower having a power driven impeller rotating about a horizontal, transverse axis to throw snow upwardly and forwardly through a chute which is substantially coextensive in width with the axial length of the impeller. A plurality of laterally spaced upright vanes are disposed in and pivotally connected to the upper end of the chute for the purpose of directing the discharge of snow. A vane adjusting mechanism includes a transverse, laterally shiftable vane adjusting bar which is connected to the vanes through pairs of laterally spaced fingers extending forwardly from the control bar on opposite lateral sides of the vanes. Lateral shifting movement of the bar effects simultaneous lateral tilting of the vanes. The vane adjusting bar includes a pair of rearwardly extending stud parts which extend through slots in the rear wall part of the transverse recess in the rear wall of the discharge chute in which the bar is disposed. The slots and stud parts cooperate to guide the control bar when it is shifted between an intermediate position in which the vanes direct the discharged snow straight ahead and laterally adjusted positions in which the vanes direct the snow discharged through the chute to one lateral side or the other. The recess for the control bar is sufficiently deep so that the control bar is disposed therein and does not interfere with discharge of snow through the chute and a resilient detent is provided to selectively, releasably hold the control bar in its intermediate and laterally adjusted positions.
