RECENTLY PATENTED INVENTIONS. Electrical Apparatus. TELEGRAPH - RELAY.- JULIO E. Con DOVER. Panama U. S. of Colombia. The In vention provides an efficient and sensitive con struction for repeating telegraph messages both with and without the use of sounders or other receivers at the intermediate sta tions and allows the use of the apparatus either for repeating purposes or for those of ordinary communication from station to station. The use of springs or like delicate and rather uncertain devices is avoided. Engineering Improvements. ROTARY ENGINE.-FREDERICK S. PICKER ING Olathe Kans. The inventor has devised an improved engine the characteristic fea tures of which are to be found in a cylin der having a central core spaced from the wall of the cylinder to form an annular working-chamber. The piston has a number of piston-heads traveling in this working chamber. A revoluble abutment extends into the annular chamber the abutment having a cut-out portion for the passage of the piston-heads. Peripheral seats for this abut ment are formed by a recess in the inner surface of the cylinder and the recess in the core the core being provided at this recess with a packing forming part of the seat. The peripheral surface of the abutment contacts closely with its seats in the recesses thereby forming a closed working-chamber and a perfect abutment for the back pressure of the steam. The core-packing is subjected to steam pressure for counterbalancing purposes. Springs engage the core-packing and act in conjunction with the steam pressure to insure a constant ex cess of pressure in the direction of the abut ment and constant contact therewith. Machines and Their Accessories. BELT-PLACER.-JORDAN S. MONTGOMERY FELIX G. OWEN and ROBERT R. OWEN JR. of Franklin Ky. The object of the invention Is to provide a simple device especially adapted for the placing of long heavy horizontally-running belts such as a belt for a threshing-machine or the like driven from an engine. The device com
