In connection with the subject-matter of claim 1, mounting the spirally grooved shaft in at least two bearings in independent cross-bars of a one-piece or integral metal frame 5, attached to the cover of a stirring-receptacle or other suitable support. (7.)

Improvements in machines for inserting fastenings.
Extract from Specification.-This invention has for its object to improve machines for inserting fastenings, the improvements being herein shown as applied to a machine such as described in Letters Patent of the Colony of New Zealand No. 12837, dated 2nd August, 1900, said machine being adapted to drive a novel fastening of our invention. Many features of this invention are, however, applicable to any machine for inserting any kind of fastenings commonly employed to attach the soles of boots and shoes, or to secure together layers of material. One important feature of the invention herein shown and described is an attachment for a machine for uniting layers of material or attaching the soles of shoes, which consists in a device to form a cut or indentation in the stock, into which cut the fastening is inserted, said cut being subsequently closed to conceal the fastening. This device, in the form herein shown, operates intermittingly and forms a series of cuts or indentations in the stock, a separate cut for each fastening. Hitherto, in the manufacture of shoes in which an opening has been formed in the sole for the thread or fastenings by which the sole has been attached, it has been the practice to form a continuous channel in the sole, the lip of leather formed in making this channel being afterwards turned down to close the opening and conceal the fastenings. Forming a continuous cut or channel in the sole in this way, of course, greatly weakens the sole. By forming separate cuts or indentations in the stock and leaving solid leather between the cuts we obviate this weakening of the stock and preserve for the sole the original strength of the stock. There is also much less danger of the cuts opening in the wear of the shoe than when the channel is continuous. It is also the practice in forming continuous channels to make a wide cut from the edge of the stock inwardly. When the edge is trimmed the channel usually extends to or nearly to the edge of the sole, resulting in a considerable weakening of the edge. When separate cuts are made, as herein explained, the edge of the sole is untouched, and will therefore stand up much better. This continuous channel is cut in the outer sole before the shoe comes to the machine employed to unite the sole to the shoe, and also, by a separate operation, the channel-lip is turned back, opening the channel to receive the fastening-material. After the sole has been attached, cement is applied, by hand or by machine, to the channel-lip, and subsequently the channel - lip is turned over by another machine, or by hand, to conceal the fastenings. Prior to this closing of the channel the channel-lip should again be moistened to put it again in temper for the closing operation, although this step is sometimes omitted. An important feature of our invention consists in a device, also constituting an attachment for a machine for uniting layers of material or attaching the soles of shoes, which is adapted to be actuated in connection with the operation of said machine and said cutting-device, to close the cuts or indentations after the insertion of the fastenings. Closing the cuts or indentations immediately after the insertion of the fastenings is of material advantage, because the stock is still damp or "in temper," as it must be when the cuts are closed, and therefore can readily be pressed back into its original condition. The operation is more effective and permanent than it would be if the stock were permitted to dry before the cuts were closed and then dampened again preliminary to the closing operation. Also, closing the cuts immediately after inserting a fastening, and while the stock is still damp, obviates the expense of moistening the soles a second time, as should be done when the lip is closed at a subsequent operation by another machine or by hand. Of course, however, the greatest advantage of combining the mechanism for opening and closing the cut for the fastenings with the machine for inserting the fastenings is the great economy which results from doing away with separate machines and separate operations for opening and closing a channel for the fastenings. We prefer so to organize the machine and its attachments that the cut will be closed after the insertion of each fastening and before the insertion of the next fastening or the formation of the next cut. When the mechanism is so arranged, the cut is formed, the fastening is inserted in it, and the cut is closed, all while the stock is clamped between the presser-foot and the work-support, and so held continuously under pressure throughout these operations, and all before the stock is fed into position to receive the next fastening. The machine to be herein described is also provided, outside the end of the wire guide-way, and beyond the point where the wire is cut in the
