HINGE!) LAST.

Application filed June 28, 1923. Serial No. 648,369.

To all whom it may concern:

Be it known. that I; FREDERICK l/V. MIL- my, a citizen of the United Statesof Amen particularly to the means 'for retaining the last extended under normal conditions, the object-of the invention being to produce a last of this character in which the spring mechanism is so mounted that it will bear directly uponfthe connecting member be w tween the two parts of the last and cannot become displaced. j

The invention consists 'primarlly in a member connectlng the forep'art of a last to the heel part thereof, and having a lateral socket in one wall thereof intermediate its ends, and in whichone end of aspring is positioned v the opposite end of said spring being disposed inasocket in the forep'art.

The invention further consists incertain novel features of constructionand arrange inent of parts which will be understood readily by reference to the description of the drawings, and to the claims to be hereinafter given. v

For the purposeof illustrating the invention, one preferred form thereof is shown in the drawings, this form having been found to give satisfactory and reliable results,. although it is to be understood that the various instrumentalities of which the invention consistscan be variously arranged and organized and the inventionflis not limited to the precise arrangement and organization of these instrumentalities as herein shown and described, except as required by the scope of the appended claims.

Of the drawings:

Figure 1 represents an elevation of a hinged last embodying the principles of the present invention.

Figure 2 represents a longitudinal vertical section of the same, and

Figure 3 represents a transverse section of the same on line 3, 3 on Fig. 2.

Similar characters indicate like parts throughout the several figures of the drawings.

In the drawings, 10 is the heel part and 11 the fore part of a divided last. The heel part 10isprovided with the usual pin socket and also has another socket 13 extending inwardly from its front face.

In this socket 13 is disposed one end of atubular member 14, tliisinserted end being rigidly secured to the heel part 10 by means ofqthe transversely disposed pins 15.

' The tubular member 1 1 is inclined forwardly and downwardly as indicated in F '2 of-the drawings, and is positioned within a pocket 16 in the rear end of thefore part 11. 7

The forward end of the tubular member 14 has a' pivot pin117"extendingtherethrough and through the fore part 11.

The upper and lower walls-of the pocket 16'are inclined to' each otherand are curved to lit the upper and lower surfaces of the tubularmember 14.

The front wa'll'of the heel part 10 has a projection 18 extending forwardly there from, the front face 1 90f which is concaved and adapted to fit the convexportion at the rear of the forepart 11. x l

The convex face 20arid concaved face 19 a' re concentric to the. axis of the pivot pin 17.

At theppposite ends of the convex port1on 20' are the shoulders 21,22 separated from each other a distance greater than the depth of the projection 18.

TheshOulder 21 is adapted to co'act with the upper face 23 ofthe projection to limit the movementof the fore part 11. about the pivot 17 when thelast' is beingshortened.

lVlien the last is extended as shown. in the drawings, the shoulder 22 is in contact with the lower face 2 1 of the projection 18.

It is desiredto have the space between the shoulder '21 and the face 23 free from obstructionsunder all conditions so that when the fore part is moved about the pivot 17, there will be nothing to hinder the free movement of the fore part 11 about the pivot 17 until the shoulder 21 comes into contact with the face 23.

For this reason, a socket 25 is formed in the fore part 11, extending from the pocket 16, this socket being substantially parallel with the concaved face 19.

When the socket 25 has been bored in the fore part 11 its outer end is closed by the plug 26.

The tubular connecting member 14 has an opening 27 in the wall thereof, in which is Ill) disposed one end of a spring 28, the opposite end of which is positioned in the socket 25.

By locating the spring in this manner, it is out of the way and cannot be displaced, while a heavier spring may be used than is ordinarily employed in lasts of this character.

There is a further advantage in thus 10- cating the spring substantially parallel with the meeting faces 19, 20, for the reason that when the parts 10, 11 are moved relatively to each other, there will be a direct endwise action on the spring 25, without any tendency to distort the same.

It is believed that the operation and many advantages of the invention will be understood readily without further description.

Having thus described my invention, I claim:

1. A last comprising a heel part and a fore part; a straight rigid member one end of which is immovably anchored in the heel part while the opposite end thereof extends into a pocket in the fore part and has a transverse cylindrical hole therethrough; a pin in the fore part extending through and fitting said hole; and a hidden spring in a socket communicating with the upper wall of said pocket with its lower end coacting with said rigid member and adapted to force the under wall of said pocket against said rigid member.

2. A last comprising a heel part and a fore part; a straight rigid member one end of which is immovably anchored in the heel part while the opposite end thereof extends into a pocket, in the fore part and has a transverse cylindrical hole therethrough; a pin in the fore part extending through and fitting said hole; and a hidden spring in a socket communicating with the upper wall of said pocket with its lower end extending partly through said rigid member, said spring being adapted to force the under wall of said pocket against said rigid member.

3. A last comprising a heel part and a fore part; a tubular member rigidly connected to the heel part and extending into a pocket in the fore part and having a lateral opening in the wall thereof, the width of said pocket being the same as the diameter of said rigid member; and an unexposed spring, one end of which extends through said opening and coacts with said member, while its opposite end is disposed in a socket in the fore part extending toward the combthereof, said spring being adapted to force the under wall of said pocket against said tubular member.

4. A last comprising a heel part having a forward projection with a concaved face; a fore part having a convex portion at its rear end conforming to said concaved face, with shoulders at opposite ends separated a distance greater than the depth of said projection and adapted to coact with the upper and lower faces of said projection; a tubular member connecting said parts, said memher being pivoted to one member and extending into a pocket in the other member the width of which is the same as the diameter of said member; and an unexposed spring mounted in said fore part above said member with one end thereof extending through an opening in the wall of said connecting member, said spring being adapted to force the lower shoulder on said fore part against the bottom of said projection.

5. A last comprising a heel part and a fore part, said heel part having a forwardly extending projection provided with a concaved front face and said fore part having rearwardly extending shoulders adapted to coact with upper and lower walls of said projection and a convex face intermediate said shoulders conforming to the concaved face of said projection; a rigid member immovably anchored in said heel part and extending through said projection into a pocket in fore part; an ,unexposed spring in a socket communicating with said pocket with its lower end extending partly through said rigid connecting member, said spring being adapted to force the under wall of said pocket against said rigid member; and a pin in said fore part extending throu h a cylindrical hole in the forward end 0 said connecting member.

Signed by me at 7&6 Old South Bldg, Boston, Mass, this 27th day of June, 1923.

FREDERICK V. MILLAY.
