The head is provided with a fluid feed slot connecting the head hole with the outside of the head. A resilient cap is assembled onto the stem for reciprocation thereon and comprises a cylindrical hollow body sized to slidably fit over the stem head guide, said cap body having a closed end and an open end.

Abstract: A track chain includes a plurality of track pin bushings as is well known, to seat in recesses defined by a drive sprocket. Each track pin bushing defines a plurality of angled protrusions which act as wear surfaces between the bushing and the sprocket, and also act to force foreign matter from recesses of the sprocket in which bushings are seatable.

Abstract: A wear plate is disclosed herein for use in a railway car center sill to prevent or minimize wearing of the upper bearing surface of each of the horizontal key slots, due to the rubbing action of a draft key. The wear plate includes an elongated wear face which is positioned between the upper bearing surface and key and covers the upper bearing surface. At least one upwardly-extending flange is provided for securing the wear plate to the center sill and for maintaining the wear face in position to protect the upper bearing surface.

Abstract: A resilient element is associated with an overlapping portion of a crawler tractor track shoe so that the adjacent shoe initially contacts the resilient element during back-bend flexure prior to the grouser of this same adjacent shoe contacting the overlap portion of the first shoe. The resilient element, by reducing impact velocity, serves to lessen operating noise and prolong shoe life.

Abstract: Apparatus is provided for reducing the noise generated by the meshing of an endless track and a drive sprocket of a track type vehicle including a pair of annular treads of resilient material. The treads are mounted about the peripheries of a respective one of a pair of cylindrical wall members provided on opposite sides of the sprocket for positioning the treads in radially aligned relationship with a respective one of the inwardly facing rail surfaces provided on a respective one of the double chains of the track. The treads are sized so that, in a free state, their outer peripheries are positioned radially outwardly of the normal position of their respective rail surfaces when the track is fully seated with the sprocket so that the rail surfaces engage and compress the treads before the track comes into full mesh with the sprocket, thereby alleviating any impact therebetween.

Abstract: In a tread for a power-driven ski having a chain with a plurality of spaced propulsion cleats, an outwardly protruding propulsion cleat, constructed with a venting passage and with resiliency to enable it to withstand the dynamic forces associated with its protruding construction, and to vent snow which is continuously becoming trapped between itself and the sprockets, while the cleat swings over and around these sprockets.

Abstract: A rotatable resilient contacting element attachable to track shoes of a crawler type vehicle.

Abstract: A pneumatic or semi-pneumatic unitary tire-wheel comprising a completely enclosed toroidal chamber bonded around a coaxial inner sleeve. A plurality of tie members are integral with and extend between the sidewalls to restrict lateral deformation thereof. Such reinforcing tie members may be hollow to give the appearance of openings between wheel spokes.

Abstract: A soup dispenser is provided with a simplified but accurate volumetric trap valve and reservoir assembly that obviates the need for venting in the dispensing of hot soup and the like with or without a high solids content. The entire unit including the valve, the reservoir and motorized impeller device for maintaining soup in the reservoir in a homogeneous condition is readily disassembled for cleaning and sanitizing.

Abstract: A rail car coupler, with the shaft thereof bearing against a coupler carrier, is vertically adjustable by means of serrated lock plates intermeshing with similarly serrated coupler carrier brackets. A minimum adjustment is therefore made possible equal to the size of a tooth of the serrations. Opposed bearing surfaces of the coupler carrier respectively lie in planes containing a trough between a pair of adjacent teeth of the bracket serrations and containing an apex of one of the teeth of the bracket serrations so as to permit a further relative adjustment of the planes containing the bearing surfaces by an amount equal to at least one-half the size of a tooth of the serrations when the coupler carrier is inverted 180.degree.. Serrations may be provided on opposed surfaces of the bracket to facilitate a half-space adjustment by inverting the brackets.

Abstract: The system includes a plurality of material discharge spouts combined with a blending device for use with a hoppered bin. Each spout opens to the hopper at a location selected to draw material into the hopper from substantially one predetermined portion of a horizontal bin cross sectional plane in a first in -- first out segregation free manner. The blending device combines the material discharge streams formed by the spouts in proportion to the areas of the portions of the horizontal bin cross sectional plane from which they are drawn, respectively, to form a common discharge stream of uniform composition. The principles of the invention are applicable to conversion of existing bins or bin bottoms, or to a bin withdrawal system or process. Also disclosed is a blending unit which includes a mass flow hopper, the blending unit being particularly suited for bin or bin bottom conversion application.

Abstract: A crawler tractor track chain drive assembly including a sprocket and a track chain having pairs of links and a track plate and connectors extending between the links and spaced from the plate. An elastomeric member is disposed in the space between the connectors and the plate and extends to be engaged by the sprocket in the driving of the chain, and thereby attenuate noise in the contact between the sprocket and the chain.

Abstract: An uncoupling lever arrangement for railway cars equipped with standard draft gear cushioning including an uncoupling lever assembly comprising a handle section and a lock lifter section, each including an elongate bar formed from tube stock of quadrilateral transverse cross-sectional configuration. The handle section has a U-shaped handle affixed to one end of its bar at the outboard end of the lever assembly, which handle is mounted in the car body bracket, and the lock lifter section bar has a lock lifter rod member affixed to the inboard end of same that is formed with the usual hook eye formed for conventional application to the coupler lock lifter. The lever assembly bars are of complementary configuration whereby one end of one of the bars is received in the other end of the other bar to support the bars, and thus the lever assembly, in their operative position from the car body bracket and the coupler lock lifter.

Abstract: This disclosure deals with a hydraulic cushioning unit for a railway car, including a gas return. The unit includes a main reservoir which is precharged with a hydraulic oil and an inert gas. At least one reservoir extension is also provided at the upper side of the unit, the extension enabling the unit to be charged with relatively large amounts of oil and gas. The oil volume when the unit is in its neutral position is approximately 76 percent of the total reservoir volume, and the reduction in the gas volume during impact conditions is not more than approximately 40 percent. The unit includes a tube and two separate charging passages for precharging the unit to the desired oil and gas volumes.

Abstract: A track-type vehicle comprises a plurality of articulated track shoes each comprising a pair of downwardly converging sidewalls terminating at a grouser extending the full width thereof. The sidewalls define a V-shaped trough-like configuration and a track link is releasably attached thereto. A pair of parallel lugs are formed on the upper ends of the sidewalls.

Abstract: A fluid dispensing anti-burglar device is disclosed which discharges a fluid, containing a chemical such as tear gas, into an area to be protected when an intruder opens a window or a door or forces open a window or a door to enter a private or unauthorized area with which the device is associated. The anti-burglar device employs a spring biased actuating member for discharging a pressurized container. A mechanical trigger for releasably retaining the actuating member in a cocked position and for releasing the actuating member to dispense the fluid, containing a chemical such as tear gas, is described. In addition, a lock mechanism to place the device in a non-triggerable condition is also shown.
