SPECIFICATION forming part of Letters Patent No. 645,038, dated March 6, 1906; Application sled July 1, 1399. senti No. 722,559. (No model.)

To aZ'Z whom it may concern:

Be it known that 1, TIMOTHY F. LYoNs, of Randolph, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Lasts, of which the following is a specication.

This invention has for its object to provide improved means for securing an inner sole to alast as a part of the lasting operation in such manner as to avoid mutilation of the last and to permit the secure connection of the inner sole to the last and its ready removal therefview of one of the sockets in the last, showing the detachable pin partly turned in position to be disengaged from the locking-tongue of the socket. one of the pins. Fig. 5 represents a perspectiveview of one of the sockets. Fig. 6 represents a sectional view of the same.

The same letters of nreference indicate the same parts in all the figures. A

In the drawings, ct a represent a series of metal sockets inserted in cavities formed for their reception in the bottom of a last.

b b represent pins formed to freely enter and be removed from the sockets a a, the pins being of such length that when inserted in the sockets their outer ends will project considerably from the bottom of the last, said outer ends being formed to readily penetrate an inner sole t' when said inner sole is laid upon the outer ends of the pins and driven toward the bottom of the last by suitable means, such as a hammer j, having a recess j' adapted to receive a pin o, as shown by dotted lines in Fig. 1.

The pins ZJ and sockets a are provided with complemental means for locking the pins in place in the sockets and preventing their accidental withdrawal, said means, as here shown, comprising notches c, formed in the Fig. I representsl two views of pins, and spring-tongues d, formed on or affixed to the sockets and projecting into the same in position to engage the notches c, as shown iu Fig. 1.

The notch c of each pin is formed in' one side only of the pin, so that by turning the pin in the socket the tongue d may be forced out of the notch, as shown in Fig. 3, thus permitting the free withdrawal of the pin from the socket.

Preparatory to lasting, the pins b are insert*- ed in the sockets ct and engaged therewith, as above described, and then the inner sole t' is placed upon one of the pins and driven down upon it and then is driven successively upon the other pins, the inner sole being thus held securely upon the bottom of the last both by the friction of the material of the inner sole upon the pins and by the different inclina tions of the pins in case the same are arranged as shown in Fig. 1. The upper is then lasted and secured to the inner sole in the usual or any suitable manner, after which the pins are turned in their sockets and then removed therefrom and from the inner sole, thus permitting the removal of the last from the upper and inner sole.

When the last is not in use, the pins may be inserted in the sockets, and thus kept in position for use when wanted, there being no liability of accidental displacement of the pins, owing to the fact that they have to be turned with sufficient force to displace the spring-tongues d before they can be withdrawn from the sockets ce. I prefer to slightly Hatten two sides of the penetrating end of each pin in order that it may be more readily grasped andturned.

I do not limit myself to the details of construction here shown, and may use anyother suitable means for detachably securing the pins in the sockets.

It will be seen that the pins and sockets enable the last to be used indefinitely without injury so far as the means for holding the inner sole in place upon the last are concerned, my invention being in this respect a great advantage over the ordinary tacks AWhich are driven through the inner sole and into holes in the iron bottom of the last and IOO into the wooden body thereof, these pins in a short time disintegrating the Wood, so that it can no longer retain the pins.

The pin b may be of smaller diameter at its shank portion, which enters the socket a, than at the portion Which penetrates theinner sole, this form enabling the pin to be readily Withdrawn from the inner sole after being released from the socket.

The projecting portion of the pin may be roughened or corrugated, so that it may be firmly grasped and readily turned.

l. A last having'a series of sockets in its bottom, combined With a series of pins adapted to be detachably inserted in said sockets and formed to penetrate an inner sole,the pins being of suflicient length to project through the inner sole and enable their outer ends to be grasped to Withdraw the pins from the sockets.

2. A last having a series of sockets in its bottom provided With locking members, cornbined with a series of pins adapted to be detachably inserted in said sockets and having sole-penetrating outer ends, and complemental locking members, said pins being of suficient length to project through the inner sole and outside ofv its outer face'.

to be inserted in the sockets and formed to.

project through and outside of the outer face of an inner sole7 each pin having a notch formed to engage one of said tongues, the notch beingformed in one side of the pin,- whereby a rotary movement of the pin causes displacement of the tongue.

5. An inneisole-holding pin having a sole- -penetrating outer portion formed to be grasped and turned, and a locking member adapted to engage a complemental locking member in a last. v

In testimony whereof I have affixed my signature in presence of two Witnesses.
