Patent for a cotton chopper. Illustration included.

Coal (or other carbonaceous matter, such as biomass) is converted into a product gas that is substantially free from hydrocarbons. The coal is fed into a solar reactor, and solar energy is directed into the reactor onto coal char, creating a gasification front and a pyrolysis front. A gasification zone is produced well above the coal level within the reactor. A pyrolysis zone is produced immediately above the coal level. Steam, injected into the reactor adjacent to the gasification zone, reacts with char to generate product gases. Solar energy supplies the energy for the endothermic steam-char reaction. The hot product gases flow from the gasification zone to the pyrolysis zone to generate hot char. Gases are withdrawn from the pyrolysis zone and reinjected into the region of the reactor adjacent the gasification zone. This eliminates hydrocarbons in the gas by steam reformation on the hot char. The product gas is withdrawn from a region of the reactor between the gasification zone and the pyrolysis zone. The product gas will be free of tar and other hydrocarbons, and thus be suitable for use in many processes.

Patent for improvements in parcel carriers for bicycles in which the parcel carriers can attach/detach easily and is adaptable to different types of bicycle handlebars; includes illustration.

Patent for "a brake which is quickly applicable to any form of wagon and which is attached to the wagon-gear only and has no connection with the body of the wagon, thus allowing the wagon-body to be entirely removed from the bolsters without interfering with the action and operation of the brake mechanism." (Lines 10-17) Includes instructions and illustrations.

Patent for a vehicle attachment that allows the driver to detach the vehicle from the horse, should the horse become difficult to control. Illustrations included.

Patent for timber-jacks which are "particularly adapted for use for persons using cross-cut saws on large pieces of timber."

A method of vitrifying soil at or below a soil surface location. Two or more conductive electrodes are inserted into the soil for heating of the soil mass between them to a temperature above its melting temperature. Materials in the soil, such as buried waste, can thereby be effectively immobilized.

Patent for a type of crate used for shipping eggs. Illustrations included.

Patent for an improved gang-plow and cultivator, including illustrations.

Patent for an improved hydrocarbon burner, including illustrations.

Patent for a tool to cover a portion of barbed wire fence allowing one to cross over or through without harm, composed of three or more telescoping metal tubes.

Patent for the development of a drill bit "specially designed for the purpose of obtaining samples of the formation through which the drill bit is passing" (lines 14-16).

Patent for a bed that is collapsible and portable but still safe and sturdy. Includes instructions and illustrations.

Patent for a new and useful electrical retort.

Patent for a clothes pin. Illustration included.

Patent for a fan actuating mechanism. Attempts to improve upon fans by using a spring to provide maximum speed at minimum cost.

Patent for a churn for separating butter. Includes instructions and illustrations.

Patent for an Advertising Device. This device provides "a series of hinged leaves so mounted that those exposed to view have the experience of being part of a book." (lines 14-17). "A further object is to provide means which will conceal the operating mechanism, and mystify the observer" (lines 23-25), with a "supporting structure and a dummy provided with a movable hand...for turning said movable shaft as the leaves are turned" (lines 3-13).

Patent for a shocker attachment for harvesters. Illustration included.

Patent for a spring wheel. Gebhardt describes the wheel as "an improvement... to provide resilient spokes which are connected to the hub and felly of the wheel in a manner to take up vibration and shocks imparted to the wheel in traveling or passing over obstructions and rough roads (p. 1, lines 8-15)." The patent also adds provisions for easy removal of spokes and a sectional felly and hub.

Patent for improvements in polishing machines for "polishing marble and other similar stones... and giving a smooth surface to any material of like character." Invention provides a "movable abrading member...and comprehends and mechanism whereby said member may be automatically moved back and forth over the surface to be polished."

Patent for a new and improved nut-locking device to securely lock fish plates to rail ends.

Patent for a washing machine. Illustration included.
