BILLBERG PORTABLE MOTORS — The accompanying cuts, Figs. 1 and 2, represent a Billberg portable motor for driving drill presses, portable reaming machines, etc., where the power is a long distance from the work. The frame of the motor is of wrought iron, to combine the most power with the least weight. The bearings are all self-oiling, of the sleeve type, and can be easily replaced. The motors are first class in construction and have improved armature commutators and self-feeding brushes. The motor is furnished with a switch and rheostat for changing the speed, and also reducing gearing so that the spindle for attaching the connection shaft can be run at 250 and 500 revolutions and eight intermediate speeds. It is fastened upon the box containing the rheostat and is covered with a wooden top with wire cloth which protects it from injury and at the same time allows a free circulation of air.
To one end of the box is attached a reel containing 100 feet of flexible connection, which will allow of the motor being used anywhere within this distance from the connection box. The motor box is mounted on wheels so that it can be rolled when at work and also has wooden batten handles so that it can be carried. These machines are made of two sizes, at present; the 2 h. p. weighing complete 275 lbs—boxed for shipment 350 lbs; the 3 h. p. size weighs complete 375 lbs.—boxed for shipment 500 lbs. Fig. 1 represents one of the motors coupled by a telescope shaft to a Dallett special portable drill. Since the Billberg motors were brought out about two years ago they have become very popular and have given entire satisfaction. Among some of the many concerns using these motors are the Franklin Sugar Refinery, William Sellers & Co., Phila.; Sotter Bros. Pottstown; Edgemoor Iron Works, Edgemoor; De La Vergne Refrigerating Co.; New York Central R. R., and Brooklyn Navy Yard, New York; Norfolk Navy Yard, etc. These special motors, as well as a standard line of motors, generators and dynamos are manufactured by Thos. H. Dallett Sedgeley avenue, Philadelphia |
