It is evident that the several parts composing the improved engine may be arranged in various ways, and that the external form thereof may be greatly changed whilst its principle of operation remains substantially as I have ascertained and described. It is also evident that the working cylinder may be placed horizontally or otherwise, and that it may be made...

The excellence and abundance of the objects of minute art would appear to indicate a high state of refinement ; but their perfection forms, however, an observable contrast to the state of articles of a more ordinary character, and extensive demand. Although much has been done in the improvement of these articles, they do not admit of comparison with the perfect execution and manufacturing skill displayed in those of a more costly description. That improvement...
Page 1448 - It is particularly worthy of notice that the relative diameter of the supply and working cylinder will depend on the expansibility of the acting medium employed ; thus in using atmospheric air or other permanent gases, the difference of the area of the pistons may be nearly as two to one, whilst in using fluids (such as oils, which dilate but slightly), the difference of area should not much exceed one-tenth. I have next to notice that in employing any other medium than atmospheric air, it becomes...

A number of blank cards are placed in the upper part of this machine, and then, by turning the handle, either by hand or steam power, the cards are delivered, one by one, ready for distribution — namely, printed from an adopted form, and numbering from one to 3,000 or more. At the same time each ticket is registered as it leaves the machine. The printing, as well as the numbering, is done with common type, in different colors. Each ticket is further checked by marks or symbols, which,...
Page 1456 - I consider the arm perfect for the dragoon service, particularly when opposed to the western prairie Indians. It is the only weapon with which we can hope ever to subdue these wild and daring tribes, unless we can have at least three regiments of dragoons on the Texas frontier alone. I consider Colt's repeating pistol equal, in every respect, to any other pistol now in use, and very greatly superior in almost every respect. " In 1837 or 1838, Mr. Colt took some of his rifles to Florida. A board of...
