For cutting the index sheets or leaves of books this inventor has devised an apparatus to be easily operated by an inexperienced person, doing the work with great precision and rapidity. The book whose leaves are to be cut is placed on an adjustable platform, when the leaves are laid on a die and beneath a presser foot, and, by stepping on a treadle. a cutter head is moved down to cut the leaves. The platform may be automatically fed lengthwise to bring successive leaves in position to be cut. COPYING BOOK. — Ed win Fowler, Kansas City, Mo. This is a letter press book having a series of sheets forming surfaces receptive of copying ink for press copying, the sheets bearing consecutive numbers or letters in copying ink, which numbers are transferred to letters copied. By this means copied letters may be conveniently designated and found in the copying book. HYDROCARBON BURNER. -— Jacob W. Rees, Cleveland, Ohio. This burner is adapted to burn either oil or gas, producing the gas from oil, and is provided with an asbestos-lined drip pan adapted to be set in the flre box of an ordinary cook stove. burners being supported on standards above the drip pan to bring the flame to the proper position. Oil burned on the drip pan generates gas in a generator supported above the pan when the apparatus is employed as a generator and urner. TYPEWRITER ATTACHMENT —William S. Bigelow, Boston, Mass. This invention provides a simple device by which the key when depressed will be held down, as when upper case or figure printing is to be done, the key being released by a natural and easy movement of the hand and finger, when such printing is finished, to throw the machine into normal position. An independent spring catch is adapted to engage and project above the key to hold it depressed, the key being released by a wiping or drawing movement of the operators finger. PHOTOGRAPHIC SHUTTER RELEASER. —Arthur M. Boos, Boston, Mass. To automatically release the shutter, in time or instantaneous work, enabling the photographer to be away from the camera while the exposure is made, this inventor has provided a device for pressing the shutter-releasmg button, the device being normally held out of contact by a fuse string, the time of burning of which regulates the duration of the exposure. MUSICAL INSTRUMENT. — Lewi s E. Pyle. Elam, Pa. This invention relates to mandolins, gnitars, etc., and provides an instrument designed to be rich in melodious tones, while it is arranged to prevent bending of the neck, and formed to fit properly on the body to facilitate executing the music.
