A Novel Toy.—Many of us can recall trotting, when small, on the foot of some older member of the family who crossing his knee would seat us on his foot and jounce us up and down. A toy (patent No. 1,008,547 granted to Claudius B. Johnson of Fulton, Mo.) simulates this ' action by means of two figures, one representing an elderly person sitting with crossed leg and the figure of a boy on the raised foot, the leg being pivoted and a counterbalancing weight being within the body of the larger figure, so' that the figure of the boy can be trotted up and down for a considerable period.

COMBINED SE CTIONAL TIRE AND WHEEL RIM— Frank M. Henry, 222 Mc-Dougal Street, Brooklyn, New York, N. Y. Some advantages over- other tires. in this invention, are : -L In of puncture it is not necessary to stop” and repair, as puncture of one ball will not injure any other part of tire and one can continue to one's destination or can repair at once in a short time. 2. A tire blow-out while going at high speed has caused the loss of many Jives and the wrecking of machines. This will not be the case if one of these balls blows out, as the rest of the tire will not collapse. 3. Requires no pumping up. 4. There is no necessity of having a tire chain to prevent slipping. 5. Skidding has been brought to a minimum. - 6. Any injured part can be replaced without tools. 7. The small cost of a section of this tire in comparison to a new one of any kind.- 8. If the saving of a life is the only thing to be considered, it would alone be worth many times the cost of any other tire. Life is worth the price of a sectional safety tire. No one knows when one will be running at high speed and a tire “blow-out” which will wreck the machine and perhaps cost owner and friends their lives or broken limbs. 9. The inventor will sell one-half interest in this patent to further its progress and will take out patents in four European countries. A side view of a wheel' with -sections of the tire in position is shown herewith. Note.—Copies of any of these patents will be furnished by the Scientific American for ten cents each.
