- Railroad Cattle-Gate
- Patent for a gate or guard to be positioned on a railroad track to prevent cattle or persons crossing the railroad track from turning up or down the track, and so avoid injury or death to cattle or persons. It is designed to be automatically activated by the passing train, and is of a simple design that is inexpensive to construct.
- Railroad Cattle-guard.
- Patent for an improved cattle-guard to keep livestock from crossing onto a railroad track or into railway property. This protects livestock and decreases railroad liability for loos of property. The invention includes a pivotal gate which runs parallel to the track that will go across the track to block animals if they try to cross the opening.

- Patent for improvements in Railroad-crossings. Noiseless and a more durable crossing, allowing for a more maintainable foundation and less repairing compared to other crossings that vibrate and cause severe shock and damage to the foundation.
- Railroad-Crossing.
- Patent for a railroad crossing that "consists in certain devices organized in a manner to secure automatic alignment of a series of movable rail-sections with the main rails of a track on which a train is traveling in the direction of the crossing, the approach of the train setting in motion the devices by which the rail-sections are controlled, and thus dispensing with an attendant at the crossing to set the contrivance for the safe passage of the train through the crossing" (lines 12-22).
- Railroad-Crossing.
- Patent for a simple and durable railroad-crossing that "consists of a center piece, and two side pieces for clamping the main track rails in place" (lines 12-14). It can be easily set up and connected with the rails.

- Railroad-Crossing Shock-Absorber.
- Patent for railroad crossings to protect the rails from contact with the vehicle wheels and to absorb the jar and vibration from passing vehicles over the crossing.
- Railroad Crossing Signal.
- Patent for a railroad crossing signal. The device is created so that the highway signal can be automatically raised or lowered at the crossing by a passing train.
- Railroad-Crossing Signal
- Patent for signaling devices designed for use along railroads and grade crossings and meant to be automatically operated upon the approach of a train by giving a visible or audible signal at the crossing which will warn travelers of the approach of the train and calcuated to avoid the occurrence of accidents. The signal device includes a track associated train operated circuit closing device for energizing a bell, flashing light, or signal arm or any other equivalence or suitable signal device located at the crossing.
