[Vol. XV. No. 373 



In the aocompan.'siag engraving is shown the latest pattern of 

 improved portable blacksmith forge, made by the Buffalo Forge 

 ■Company. The disliaguishing features of this forge are, easy 

 Jever and swivel movemeats; steady powerful blast for heavy 

 work, and even, light blast for light work ; no dead centre to 

 ■overcome in starting ; all of which are important factors in the 

 successful working of a forge. The bearings, which are of har- 

 dened steel and of more than ordinary length, deserve comment 

 also. By referring to the illustration, which shows the No. 

 size, it will be seen that the forge has a large fan-case, 14 inches 

 in diameter, which affords a maximum blast with a minimum 

 ^expenditure of power. A point of iuiportance is that the blast 

 ■continues some little time after a stroke is made, sufficient to 

 .allow the operator to work upon the iron quite a while before it 

 ceases. 



This forge is also arranged for belt attachment, for general use 

 in large shops where power is used. When run by belt, a cut-off 

 for the blast is provided, which permits of the fire bemg regulated 

 to any required degree. 



The armature is thoroughly insulated, and can be removed 

 very quickly if necessary. The brushes, being at the top, can 



The A. B. C. Electric Motor. 



One of the latest additions to the long list of small electric 

 motors now in the market is shown in Fig. 1. It is made by 

 the A. B. C. Motor Company of this city, and embodies some 

 •of the ideas of Mr. Brown of that company. 



The A. B. C. motor is designed so as to obtain, with a small 

 ■expenditure of current, a maximum amount of magnetism, and 

 to produce a machine that will do its work at a high rate of 

 efficiency over a wide range of power, and at a moderate and 

 constant speed under all loads. The field-magnets are lami- 

 nated, permitting the use of sheet iron, a form in which soft, 

 pure iron can be obtained of uniform quality. The several 

 laminated sections, as shown in Fig. 2, are bound together, 

 not by means of bolts passing through them in the usual man- 

 ner, but by an arrangement of rods fitting into the notches 

 «hown, which are formed by the die in the outer edges of the 

 plates. By means of this construction any irregularity caused 

 by inexactness in the separate punching of holes is rendered 

 impossible. The field-magnet has but one coil, and conse- 

 quently no yoke is necessary in its construction. The field- 

 magnet is ample in cross-section, and as short as possible, the 

 ■entire space between the limbs being filled by the coil and the 

 armature. This form of construction gives a magnetic circuit 

 ■of very low resistance. 



also be readily inspected; and, the armature being elevated, it 

 is not necessary to place the motor on a special base when re- 

 quired for fan purposes. The mechanical construction of the 



motor throughout has been carefully attended to, and all the 

 details of the motor have been well worked out.

A Hew Method of Treating Disease. 



HOSPITAL REMEDIES. 



What are they ? Tliere is a new departure in 

 tlie treatment of disease. It consists in the 

 collection of the specifics used by noted special- 

 ists ofEiirope and America, and bringing tliem 

 within the reach of all. For instance, the treat- 

 ment pursued by special physicians who treat 

 indigestion, stomach and liver troubles only, 

 was obtained and prepared. The treatment of 

 other physicians celebrated for curing catarrh 

 was procured, and so on till these incomparable 

 cures now include disease of the lungs, kidneys, 

 female weakness, rheumatism and nervous de- 

 bility. 



This new method of " one remedy for one 

 disease " must appeal to the common sense of 

 all sufferers, many of whom have experienced 

 the ill effects, and thoroughly realize the ab- 

 surdity of the claims of Patent Medicines which 

 are guaranteed to cure every ill out of a single 

 bottle, and the use of which, as statistics prove. 

 has I uined more stomachs than alcohol. A cir- 

 cular describing these new remedies is sent free 

 on receipt of stamp to pay postage by Hospital 

 Remedy Company, Toronto, Canada, sole pro- 

 prietors. 



DO you INTEND TO BUILD? 



We offer an Atlas of Sensible Lo^v Cost 

 Iffoiises, a portfolio 11x14 inches, containing 

 liasidsouie illu«ii-atioiit>>9 floor plans, and full 

 descriptions of this popular design, and fifty-four 

 others, ranging in cost from S80b to S7,200. This 

 specimen design is for a cottage with seven rooms, 

 and costing $1,100. It combines beauty and comfort, 

 has two large porches, and is a popular aud practi- 

 cal working design, having been built several times 

 for its estimated cost. 



No matter what styl^? of a house you may intend to 

 build, it will pay you to have this book. 



We will send this Atlas, postpaid, on receipt of
