624. Mouth Guard.—If you can invent a mouthguard which will be both simple and ornamental and prevent contamination when drinking at public fountains or in partaking of the communion cup in churches, you will confer much favor upon the community and reap large funds for yourself.
625. Parcel Fastener.—A hook and eye capable of instant insertion in the wrapping of paper parcels would be sold by the million.
Section 17. Money in Household Conveniences.
626. The Warning Clock.—A clock which will give notice of its wants when it is nearly run down. A simple device which it should be easy to contrive and quick to sell.
627. A Slot Gas Machine.—One which will operate a certain length of time by the payment of a nickel and automatically close when the money’s worth is consumed. It would be invaluable for small consumers.
628. Revolving Flower Stand.—A clock-work device so that all plants in a cone or pyramid could get their share of a sun-bath.
629. Window Shade Screen.—The inventor would make a fortune who could devise something for windows which would be a shade or screen or both as occasion required.
630. Baby Walker.—A light frame, mounted on four casters, partially supporting the baby and permitting him to propel himself in any direction. Only the four posts need to be made of wood. For the rest, two or three light pieces of cloth are sufficient. It should not cost over fifty cents—better at twenty-five cents. Every mother with a baby would want one at the latter price.
631. Detachable Shower Bath.—Every house should be equipped with a shower-bath, but few have one which can be readily attached to and removed from the supply pipe of the bath room. A cheap article would have an almost universal sale.
632. Carpet Beater.—Every husband would buy a machine that would beat carpets and thus save himself that drudgery or the expense of hiring a man.
