US Patent:

8376160, Feb 19, 2013
Filed:

Apr 25, 2011
Appl. No.:

13/093464
Inventors:

Charles T. Bomgardner - Burleson TX, US
Ike S. Sowden - Columbus NJ, US
Andrès Paul Montoya Moncayo - North Plainfield NJ, US
International Classification:

B61G 9/20
US Classification:

213 505, 213 61
Abstract:

A key retainer for retaining a draft key in the key slot of a railway car yoke is mounted on the outside of the sill of a railway car. Mounting the key retainer with a retainer key system on the outside of the sill, and aligned with the sill cutout, permits ease of visual inspection of the retainer from outside the railway car, and allows for repair of the key retainer without disassembling the coupler from the yoke, or the yoke from the railway car.

Railcar Shock Absorber With Neutral Position

US Patent:

56428235, Jul 1, 1997
Filed:

Jun 9, 1996
Appl. No.:

8/666920
Inventors:

Harry B. Kalina - Arlington TX
Charles T. Bomgardner - Burleson TX
Richard N. Hodges - Arlington TX
Assignee:

FM Industries, Inc. - Fort Worth TX
International Classification:

B61G 908
US Classification:

213 43
Abstract:

A railcar shock absorber has neutral position in which the piston is spaced between buff and draft ends of the cylinder. An external spring is mounted to the shock absorber. A slider rod has one end mounted to the coupling to move relative to the frame of the railcar. The spring has retainers on each end, and the slider rod passes through the retainers. One of the retainers is stationary relative to the frame. The other retainer floats relative to the frame and will abut a neutral stop of the frame when the spring is in the maximum length position. An engagement member on the slider rod will further compress the spring if a draft shock occurs from the neutral position. If a buff shock occurs from the neutral position, the engagement member moves away from the floating retainer.

US Patent:

47398892, Apr 26, 1988
Filed:

Sep 25, 1986
Appl. No.:

6/912306
Inventors:

Charles T. Bomgardner - Burleson TX
Assignee:

Halliburton Company - Duncan OK
International Classification:

B61G 902
US Classification:

213 43
Abstract:

A cushioning apparatus for a railway car includes a housing having a cylinder bore disposed therein with an end plate closing one end of the cylinder bore. A piston assembly includes a shaft extending through the end plate and a piston disposed on the shaft and slidably received within the cylinder bore. The piston is slidable between an axially innermost position furthest from the end plate and an axially outermost position closest to the end plate. A limit pin has an interference fit within a pin bore of the end plate and extends outward therefrom toward the piston for initially limiting axially outward movement of the piston short of its axially outermost position to thereby limit a length of the cushioning apparatus prior to installation of the cushioning apparatus in a railway car.

US Patent:

50259385, Jun 25, 1991
Filed:

Dec 13, 1989
Appl. No.:

7/450170
Inventors:

Charles T. Bomgardner - Burleson TX
D. Bradley Dumler - Arlington TX
Assignee:

FM Industries, Inc. - Ft. Worth TX
International Classification:

B61G 900
US Classification:

213 43
Abstract:

A rail car cushion apparatus comprises concentric cylinder and housing members mounted at one end to a seat of a cushion apparatus body and at the other end to a cylinder head. The cylinder head includes a flow chamber and flow passages. A sleeve valve chamber is also included in the cylinder head adjacent to the flow chamber. A sleeve valve is provided in the sleeve valve chamber and is slidably mounted to slide along a piston rod telescopically received in the concentric cylinder and housing members. The sleeve valve is confined for limited movement by a sleeve retainer lip provided in the cylinder head. The retainer lip is discontinous to provide space for the sleeve valve to be inserted into the sleeve valve chamber. The sleeve valve retainer lip alternatively may be formed by a flexible retainer member retained in a groove formed in the cylinder head.

US Patent:

57622140, Jun 9, 1998
Filed:

Jan 9, 1997
Appl. No.:

8/780361
Inventors:

Charles T. Bomgardner - Burleson TX
Assignee:

FM Industries, Inc. - Fort Worth TX
International Classification:

B61G 908
US Classification:

213 43
Abstract:

A shock absorber for a railcar locates within a center sill of the railcar. The shock absorber has a housing that moves relative to the center sill. A backstop is welded to the center sill for retaining the piston shaft. The backstop has a top, a bottom and two parallel sides. The height of the backstop from the bottom to the top is substantially less than the center sill. The sides of the backstop are welded to the sidewalls of the center sill in a position which provides an upper clearance between the top of the backstop and the top wall of the center sill and a lower clearance between the bottom of the backstop and the bottom of the center sill.
