It is shown by the author's experiments that hydrogen which escapes to the atmosphere through openings in the system may burn spontaneously if it contains dust. Purely thermal reasoning can not account for the combustion. It seems to be rather an electrical ignition. In order to determine whether the cause of the spontaneous ignition was thermo-chemical, thermo-mechanical, or thermo-electrical, the experiments in this paper were performed.

This is the third in a series of investigations of the water pressures on seaplane floats and hulls, and completes the present program. It consisted of determining the water pressures and accelerations on a Curtiss H-16 flying boat during landing and taxiing maneuvers in smooth and rough water.

Patent for improvements on a battery plate and terminal connections. Plate lugs and the terminal for the battery are a solid piece to fit more battery sizes and prevent the lugs from breaking off.

Patent for a method of expelling debris and deposits in a foot valve, including illustrations.

Patent for a wheel and shaft designed for use in drilling oil and gas wells.

Patent for a sash attachment that steadies the movement of the window sash within a window frame and prevent rattling.

Patent for improvements in locomotive driving boxes. Designed to "eliminate the necessity of removing the driving wheels" (lines 13-14) to replace the crown brasses, "eliminate the necessity of removing the driving box" (lines 16-17) to avoid lateral wear, and eliminates the necessity of expensive machine work.

Patent for an adjustable wire stretcher.

Patent for a vehicle wheel with a tire that is improved with a spring cushion.

Patent for an improved pump piston used to pump oil from deep wells. The main improvement in this piston is that it is less susceptible to damage from sand or sediment by keeping sediment out of the piston valve, thus preventing it from accruing any long term damage that may render the piston irreparable. This design is also capable of fixing any wear due to sand or grit without removing the piston from the well.

Patent for new and useful Improvements in Marine Vessels. Relates to marine vessels used for towing timber.

Patent for improvements to stamping-machines used for the purposes of marketing nuts. The device can efficiently perform the laborious act of stamping individual nuts with a trademark. It can be adjusted to stamp nuts of any size, along with other similar objects, without breaking or injuring the nut.

Patent for an improvement in Pump-Plungers. "It has a particular application to pumps of this character for use in oil or water wells where the liquid is mixed with sand" (lines 13-16), including illustrations.

Patent for improvements to vehicle spring wheels to replace pneumatic wheels, "embodying in its use relatively movable members having coil springs interposed therebetween whereby to secure the proper resilience" (lines 13-16) necessitating very few parts, including illustrations.

Patent for a sample taking device used in the process of drilling wells using water and a multi-armed unit that rotates to drill the stem into the ground.

Patent for a railway cattle guard whereby the weight of the animal causes a barrier to emerge, but the barrier will be removed automatically when the weight is removed.

Patent for rules and slugs that are quickly and easily arranged and that lock securely to make a type form, including one illustration.

Patent for the improvement of the pipe wrench for heavy construction. This invention was made to allow workers to use a variety of parts and arrangements depending on the type of pipe they are working with.

Patent for a new and improved peanut roaster with a rotating drum that can sound an alarm after a certain interval of time and can be moved directly over a roasting flame, including illustrations.

Patent for a signaling boiler designed to test food during the cooking process to determine whether food has completed cooking, and to signal via a whistle when said food is determined to have been properly cooked. Additional design details include the provision of a supporting mechanism for potatoes and other vegetables to rest on, as well as a compact form of the overall device.

Patent for an improved plastic roofing tile with sealing, locking, pseudo-dove tail joints.

Patent for an improved tool that is affixed to tire-patch containers. It is used for abrading the surface of a tire to effectively roughen it (without the use of sandpaper) to allow the adhesion of a patch. Includes illustrations.

Patent for an improved process of constructing convertible stock and freight train cars, including illustrations.

Patent for calipers that make it easier to read measurements, by having a strip of measuring tape at the ends that allows users to determine the distance between the arms easier. The measuring tape component is also retractable.
