Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
105 words
A machine for vibrating railroad rail comprising: a. a rail-carried vehicle; b. an elongated shoe adapted to engage the upper surface of the rail; c. vibratory means mounted centrally of the shoe and acting to cause rail vibration in a vertical plane alined with the rail; d. a vertical guideway on the vehicle; e. a slide assembly movable along the guideway; f. spring means in said vertical plane reacting between said assembly and the opposite ends of the shoe and g. means to position the assembly on the guideway so as to load the spring, whereby the shoe is held in engagement with the rail.
Claim 2
Dependent Claim
105 words
A machine for vibrating railroad rail comprising: a. a rail-carried vehicle; b. an elongated shoe adapted to engage the upper surface of the rail; c. vibratory means mounted centrally of the shoe and acting to cause rail vibration in a vertical plane alined with the rail; d. a vertical guideway on the vehicle; e. a slide assembly movable along the guideway; f. spring means in said vertical plane reacting between said assembly and the opposite ends of the shoe and g. means to position the assembly on the guideway so as to load the spring, whereby the shoe is held in engagement with the rail.
Claim 3
Dependent Claim
43 words
The machine defined in claim 1 in which said spring means comprises: a. bow leaf spring means, extending in the direction of the rails and connected, at its midpoint, to said assembly and, at its ends, to the corresponding ends of said shoe.
Claim 4
Dependent Claim
25 words
The machine defined in claim 1; and a. a propulsion engine to drive the vehicle along the track while the vibratory means is in operation.
Claim 5
Dependent Claim
63 words
The machine defined in claim 3, in which said vibratory means comprises: a. a rotary hydraulic motor mounted on the shoe b. a weight eccentrically mounted on a shaft driven by the motor, said weight moving in said vertical, plane; and c. a pump carried by the vehicle, driven by said engine and hydraulically connected with said motor to form a hydrostatic transmission.
