THE BOOK CLAMP.
Herman Dieck translation
The clamp is used to hold several books together which are to be immersed at the same time into the marbling trough. They are of iron entirely, are eccentrical in their movement and make a very quick handling and an easier holding of the books possible.
APPARATUS FOR THROWING ON COLORS.
For the purpose of producing nonpareil marble an equal distribution of color is desirable.
It consists of four small color receptacles and apparatus from which protrude needles equi-distant from each other in the form of a rake.
The throwing of marble-colors at equal distances and in equally large drops on the size is made possible by it in a very certain and easy way and is even a good help to the inexperienced marbler in the production of even and exemplary edges. For the production of comb-marble on a large scale this apparatus is especially profitable as by using it much time is saved.
