i v SFEdIFICATION forming part of Letters Patent No. 583,404, dated May 25, 1897.

Everett, in the dounty of Middlesex and State; of Massachusetts, have invented a. new and useful Improvement in Lasting-Machines, of which the following, taken in connection with and described in Grandy,

the accompanying drawings, isa specifica tion.

My invention relates to lasting-machines in which lasting plates or wipers are employed for wiping the upper over the last at the toe and heel, and more particularly to an improved last band or clamp for use in such a machine. l

The object of my invention is to simplify the construction of a' lasting-machine of the type mentioned, and to improve its operation by so arranging the last' band or clamp that it will be carried by thelasting plates or wipers, and thus be quicker and more accurate in operation than those heretofore used.

A further object is the production of a last band or clamp which shall be readily ad j nstable to various sizes and shapes of lasts.

To this end my invention consists of a last band onc'lamp carried by and movable with the lasting-plates also of a lastband or clamp eomposed of sections elasticallyconnected together inorder that it may adjust itself to the end of the last; and it further consists of the details of construction which are hereinafter particularly pointed out and, claimed.

My invention is fully described in the followingspecification and illustrated in the accompanyingdrawings, in which Figure I is a plan of the lasting-head of a lasting-machine with the last band or clamp attached. Fig. 2 is a reverse plan view, partly in section, of the lasting plates or Wipers, showing the relative location of the last band or clamp to the edges of the lasting plates or facing-pad,which mayconven'iently beformed II, which may be 95 wipers; and Fig; 3 is a front edgeview.

For the purpose of illustrating my invention I have shown it as applied to a lastingmachine similar in construction to that shown United States patent to dated January 7, 1896, No. 552,834; but it is obvious that my invention relates generally to all that class or type of lastingmachines wherein lasting plates or wipers are Application filed May 27, 1896. Serial Ila-593,220. (N0 model.)

employed I have selected the toe-lasting devices of this machine for the purpose of illustrating my invention; but I desire to state that it is equally applicable to the heellasting devices.

Intlre drawings the bearing 5, the wormgear 7 the worm 8, the lasting-plates 10, the

- stem 14, the cross-bar 13, links 24, and handmay be the same as parts lever. 19 are or designated by similar reference-numeralsTin the machine of the patent above referred to, the lasting-plates being slightly altered to adapt them to carry the last band or clamp.

4 My last band or {clamp is shown as. com- 6 5.

but it is obvious that posed of threesections, I any 'desired huniberof sections could beisubstituted therefor. These sections may be fprmed of' the block B and the intermediate chain-links A, and I struction to be very satisfactory in use. The

' blocks B may conveniently be square in crosssection and are each connected to the intermediate section A by some suitable. flexible and-preferably extensible articulation orcon- 7 nection, so constructed that the sections 'may have a free relative swinging movement and a limited relative extensible movement. The connection shown has been found to be well adapted for the purpose, and consists of short coiled springs W, which are secured at one of their ends in recesses W in the blocks B,.and at their other ends are .pivotally connected to the intermediate section A by thelpins The section A is chain-links, which arepivotally connected to H? preferably each'other by the pin 1). Instead of forming" the intermediate section of thelinks I may substitute therefora coiled spring'of sufiicien t length o space the distance between th blocks Bflle lends being fitted therehnas-in v The blocksB ar I,
