Patent Office attachments seem a very fa-vorite theme for our inventors to workupon. This arises from the fact thata greater degree of variety can be ob-tained in matters that are merely sub-sidiary than in prime factors. Theworking parts of the locomotive havereached a degree of perfection that hasleft the inventor little room for improve-ment. The selections from last months LOCOMOTI\E. A design for a locomotive having sev-eral novel features has been patented byMr. Emilio M. Canto, Santiago, BLOW-OFF VALVE report show considerable ingenuity, andwe select a few of the most notable forillustration and description. BLOW-OFF VALVE. Mr. H. F. Weinland, Springfield,Ohio, has patented a blow-off valve, ,178. The valve is suitable for useon steam boilers, and comprises a casinghaving an inlet passage and a seatlessoutlet passage, and a piston valve fittingthe outlet passage, adapted to close thepassage by peripheral contact with thewall, and movable into and out of saidoutlet passage at its inner end, the in-ner end being flaring, whereby erosionof the edges of the valve is avoided. Aremovable bushing is fitted in the upperportion of the transverse passage. Alever that may be adjusted to any lengthis adapted to readily opening or closingthe valve. BRAKE SHOE. A variety of brake shoes have beeninvented and patented by Mr. J. F. Mor-rison, Chicago, 832,145-6. The chief
