TOP LIFT ATTACHMENT Filed Sept. 13, 1932 Wibzeuu' Patented Feb. 20, 1934 1.947.840 TOP LIFT ATTACHMENT James F. Fitzsimmons, Belmont, Mesa, assignor to Fitz-n Sales Corporation, Boston, Mass., a corporation of Massachusetts Application September 13, 1932 Serial No. 632,938

2 Claims. (Cl. 36-36) The present invention relates to attachments for detachably securing a top lift to the heel of a boot or shoe, and is particularly concerned with improved means for rigidly securing the top lift 6 to a holding post or the like adapted for insertion in a cooperating heel base.

With this in view, the various features of the invention consist in certain novel features of construction, combinations and arrangements of 10 parts hereinafter described and. claimed, the advantages of which will be obvious to those skilled in the art from the following description.

In the accompanying drawing illustrating the preferred form of the invention, Fig. 1 represents an elevation partly in section of a heel with holding post secured thereto; Figs. 2 and 3 are views showing the post and cooperating plate in perspective; Fig. 4 is a perspective illustrating the post and plate in assembled relationship; 20 Fig. 5 is an elevation partly in section of the post permanently secured to a top lift of rubber, leather or the like; and Fig. 6 is a perspective illustrating a modified form of construction in which the plate is assembled below the post rather than superimposed thereon.

The present invention relates to that type of construction in which a wooden heel base 10 is provided with a metal socket 12 of generally noncircular formation assembled therein and ex- 80 tending lengthwise thereof. Cooperating with this socket is a demountable post of similar crosssection rigidly and permanently carrying at its outer end a top lift of suitable material.

According to the present invention, means are provided for insuring permanent attachment of the post to the top lift in a simple, relatively inexpensive manner, in such a fashion that not only is the post reinforced against pressure upon the top lift during wear, but in addition accidental 4o loosening or dislodgment of the top lift from the post is effectually prevented. To this end the post is preferably formed with a flat blank and rolled into generally triangular conformation, as indicated at 14. At its lower end the post is provided with offset holding lugs 16, which may be three in number, a single lug projecting from each face of the triangle. Cooperating with the post is a complementary plate 18, having a triangular opening 20, which fits about the post 60 and provided with downturned lugs 22, which are located between the lugs 16 when the plate is assembled with the post, as indicated in Fig. 4.

With this construction a top lift indicated at 30 is permanently secured to the outer end of the post through the clinching of the

lugs

16 and 22 therein, the parts being united into a single indivisible whole, and the plate with its extending lugs effectively reinforcing the grip which the post lugs exert upon the top lift. Furthermore,

in those cases where excessive wear of the top lift before replacement has resulted in wearing away or breaking off of the securing lugs which hold the top lift in position, the employment of the plate provides a means by which a tool may be effectively employed for dislodging the post 63 from the socket. Without the use of the plate, removal of badly worn members with distorted posts may be a matter of considerable difficulty.

In the modified form of construction shown in Fig. 6, the plate is indicated at 32 and is pro- 10 vided with downturned lugs 34 located between the lugs 16 and the post. The two sets of lugs cooperate to effectively clinch the top lift when in assembled relationship. With this construction the wearer of the top lift is warned of the Is necessity for replacement by contact between the metal plate and the pavement or other surface before wear has progressed to such an extent that it interferes with or damages the wood heel base or the covering thereon, which otherwise might so occur.

What is claimed is:

1. An attachment for top lifts or the like comprising a tubular post having offset holding lugs at one end, and a plate surrounding the post and as having similar holding lugs which extend between the lugs of the post when the plate and post are in assembled relation, the two sets of lugs cooperating for the retention of a top lift.

2. An attachment for top lifts or the like com- 9 prising a tubular post of non-circular cross-section having offset holding lugs, a plate having an opening conforming to the cross-section of the post adapted for assembly thereover and having holding lugs which in assembled relation extend 5 between the lugs and the post, the plate resting upon the offset portion of the post, and the two sets of lugs combining to grip and hold a top lift.
