LASTlNG-WIACHINE.

SPECIFICATION forming part of Letters Patent No. 511,835, dated January 2, 1894.

Application filed December 9, 1890. Serial No. 374,083. (No model.)

To to whom it may concern: two reduced portions or necks E and F to Be it known that I, EDGAR S. COMBs, a citi which the formers O and O are respectively zen of the United States, residing at Rochesadapted to be applied. ter,in the county of Monroe and State of New Upon an inspection of Fig. 4 it will be ob- 55 5 York, have invented certain new and useful served that the formers have at their ends L- Improvements in Lasting-Machines,of which shaped slots G to fit upon and to receive the the following is a specification. necks E and F of the pins or studs D.

This former C which are commonly employed in pairs, both comprises a main bar or body and lateral projaws being of like construction and each jecting bearingfaces which may be formed by mounted upon suitable supporting and actua series of pins H as shown in Figs. 1 and 3,01 ating mechanism, which. however, is not byacurved plate or flange Ilas showninFigs. 8 5 shown, as it forms no part of the present in- 5 and 6.

This ers O and O. The fingers B are adapted to former C will be applied to the outer neck or 90 move lengthwise through the stock or bodyA reduced portion F of the pins or studs D,and so that their inner edges may assumea curved it will be seen upon reference to Figs. 3, 5 and line corresponding to the inner face of. the 6 that when this former is thus applied its last, or a straighter line to conform to the bearing faces will maintain the inner edges outer side of the last,-the fingers being held or ends of the blades or fingers in a slightly 5 in their different adjusted positions by means curved line conforming to the outside of the of the formers O and O which are adapted to shoe or last. When it is desired to last a left bear against the outer ends of the adjustable shoe the former O is applied to the necks E fingers substantially as in my application of the studs D on one jaw, and the former O above referred to. Projecting from the outer applied to the necks F of the studs D of the 10: 5o face of the body of the jaws are two pins or opposite jaw, the result of which is that the studs D D, each of which is provided with fingers of the respective jaws are made to conform to the sides of the last or shoe upon which they are to operate. Now when it is desired to last a right shoe the position of the formers O O is reversed; that is to say, the former C is removed from one jaw and placed upon the reduced necks E of the studs D on the other jaw, while the former O is applied to the outer reduced necks F of the studs formed upon the jaw to which the former O was formerly applied. It will therefore be seen that by simply transposing the formers O and O the machine may be instantly adapted for working either upon rights or lefts, the construction of the formers being such as to insure the bringing of the fingers to the requisite and predetermined lines.

Having thus described my invention,what I claim is- 1. In a lasting machine, the combination of two jaws, each provided with a series of Iongitudinally-adjustable fingers; a removable former or bar applied to one of the jaws and having a bearing face to bring the fingers of said jaws into a position to conform to the inside of the last; and a second removable bar or former applied to the other jaw and having a bearing face to bring the fingers of said jaw into a position to conform to the outside of the last.

2. In a lasting machine, the combination of two jaws each provided with a series of longitudinally-adjustable fingers; and a pair of removable formers applied to said jaws, each of said formers having two bearing faces, whereby they are adapted to be interchangeably used upon the jaws to bring the fingers into position for lasting rights or lefts at will.

3. A lasting machine jaw having a series of longitudinal adjustable fingers or blades and the studsD provided with the necks E and F, in combination with the removable and interchangeable formers G and C.

4. In combination with a stock or body provided with longitudinal adjustable fingers and the studs D having the necks F, the former 0' provided with the lateral projecting stops or projections adapted to bear upon the outer ends of the fingers.

5. In a lasting machine, two jaws each provided with a series of longitudinally adjustable fingers, a fiat faced former O, and a former 0' provided with lateral projections,- said formers O and 0' being adapted to be applied to either of said jaws, all substantially as shown and described.

In witness whereof I hereunto set my hand in the presence of two witnesses.
