Combined with a draught pipe is a cone with cllrved volutes, and in its center and underneath it an inverted cone, with spark pockets, and other novel features, the sparks being returned to the fire box, the invention being an improvement on two former patented inventions of the same inventor. A steam condenser has been patented by Mr. John McIntyre, of New York City. It is cylin. drical in form, a central perforated or slotted casing being used in connection with the cooling pipes, with a
more » ... pipes, with a regulating valve to open or close the perforations or slots, in such way that the cooling effect will be more instant and the temperature of the cooling parts more eq ual than in ordinary condensers. A car coupling has been patented by Mr. George W. Giles, of Buffalo, West Va. In con· nection with a suitable drawhead, a weight and pin are joined by a fiexible connection, the weight being adapted to overbalance the pin, and tbe weight being projected into the path of the draw bar, so that the en· tering draw bar will raise the weight, and thus permit the pin to fall by its own gravity into coupled position. A car coupling has been patented by Mr. Wesley E. Roberts, of Hartford, Ky. The coupling link consists of a straight bar, with a wedge shaped pointed lug at each end, a spring 'being fastened to the nnder side, and the coupling being effected by an arm dropping in front of the lug after the link enters the drawhead, the device being simple in construction, and one which can be operated from the side or top of the car. ••• AGRICULTURAL INVENTIONS. A mower has been patented by Messrs. 'James E. Nieth and Charles L. Thomas, of Independ. ence, Iowa. This invention covers a novel construction and combination of various parts of the machine, so .that it will operate with less friction than ordinary mowers, while being simple in construction and not liable to get out of order. A plow has been patented by Mr. Thomas J. Eriom, of Union Church, Miss. It is an im· . proved garden plow, with simple means for adjusting. the J:auge wheel to regulate the depth of workiug, and tt breast bar for pressure by the operator to increase the propel'ing power and to give the plowman a better con· trol of the plow, with other novel features. ••• KISCELLANEOUS INVENTIONS. An attachment for elevator doors has bee n patented by Mr. Edward P. Walker, of Kansas City, Mo. It is an attachment designed to effect by the movement of the elevator car the automatic operation 9f the doors of the shafts, so that the elevator man is zeiJe.\'�of ,this duty. A saw gummer has been patented by Mr. Eli Rogers, of Fulton County. Ind. The invention consists of a cam lever operating a spring arm on which I; pivoted a tool holder, making a device which is Bimple in construct.ion, durable, and effective in opera· tion. A hame has been patented by Mr. John E. James, of Mossy Creek, Ya. It is so made that the shoulder of the horse will not be affected by heavy jars, and the hames may not only be fitted to any length of collar, but the point of draughtmay be shifted, so that the drallght will be brought to the proper point. A tongue support has been patented by Messrs. Charle� W. Yan de Mark and Calvin Moore, of Clyde, Kansas. The construction is such that the tongue may be supported so as to relieve the team of its weight, and the devices for supporting it are simple, inexp . ensive, and not likely to get out of order. A fence post has been patented by Mr. John J. Kimball, of Nal>"rville, Ill. Combined with side strips are rivets, spacing strips arranged between the side strips, clips formed with apertures, and staples arra nged to pass through the apertures, making a cheap, durable, and e1licient post for barbed wire fences.
