It has a driving wheel with a central passage, and curved passages radi ating therefrom to and through the periphery of the wheel, to receive and discharge the steam or other driv ing fl uid admitted under pressure through a hollow shaft of the wheel from a supply pipe. An automatic railway gate has been patented by Mr. James K. Patterson, of Crete, Neb. It has main bars pivoted to a side post, and pickets hing ed to the bars, so that as the gate is lifted vertically by the weight of an
more » ... ing train, the pickets will hang down somewhat as a fan closes, and after the train has passed the gate will come down in place main ly by its own gravity. A corn planter has been patented by Mr. John A. Cherry, of Roads, Mo. By this device the .com is clucked by knife blades mounted on a revolving a.xie, which mark the ground at every hill of com deposited, and the weight of the driver is utilized to effect the desired pressure on the runners and wheels for working the marking knives. of Deerbrook, Miss. It is more especially intended for planting cotton seed, and provides means whereby the seed discharged at o';e time can be regulated, the Boil packed upon the seed and the top of the row rounded and the plows adjusted to work at any desired depth or be supported above the grou\ld. ••• IIlSCELLANEOUS INVENTIONS. A revolving sign has been patented by Mr. John F. Bengert, of Brooklyn, N. Y. Tbis inven tion covers a manner of constructing signs in such way that they will be revolved by the wind, and thus attract attention, the construction being simple, and signs so put up not liable to get ou t of order. A lathe chuck has been patented by Mr_ Edward Pement, of Esmond, Dakota Ter. This inven tion:relates to improvements on a recently patented im· provementof the same inventor, and provides a simpli fied construction, intended also to render the chuck mbre effective. A blind slat adjuster has been patented by Mr. Peter Rundqui.t, of New York city. The slats have end recesses, and cranks with side lugs on their stems engage with these recessed ends to tum the slats, while the slats can thereby be readily adjusted to any desired angle. A cabinet for tobacco, cigars, etc_, has been patented by Mr. Charles N. Swift, of New York city. It has a water receptacle and novel construction of capillary conductors, wher�by the air throughout the interior of ' the cabinet may be kept at uniform humidi ty, and the degree of moisture may be readily regulated.
