TOP LIFT ATTACHMENT Filed Aug. 51, 1932 INVENTOR Patented July 2 1935 2,006,401 Tor LIFT ATTACHMENT Fred Maccarone, Brooklyn, N. Y., assignor to Fitz- On Sales Corporation, Worcester, Massaa corporation of Massachusetts Application August 31,
. comprise the employment of a tubular socket extending lengthwise of the wooden heel base, and cooperating post permanently attached to a top lift which enters the socket and is engaged thereby to hold the top lift in predetermined relation to the heel base during the period of normal wear or usage. I
The purpose andobject of theinvention is to simplify and improve constructions of this character whereby the attachment may besimple and inexpensively manufactured, and will eiiectively serve the desired purpose of permitting removal of a worn top lift while at the same time maintaining the top lift in use in predetermined and close-fitting relationship to the supporting heel base.
With these and other objects in view, the various features of the invention consist in certain novel features of construction, combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be obvious tothose skilled in the art from the following description.
In the accompanying drawingillustratingthe preferred form of the invention, Fig. l is an elevation partially in section of one form of the improved attachment; Fig. 2 "is a view of the blank of which the holding post is formed; Figs 3 and 4 are elevations partly in section of the top lift with the post secured thereto and the hold ing spring in place; Fig. 5 is a top plan view of the construction shown in Fig. 3; Figs. 6 and '7 repre.-,
sent an elevation and, section, respectively, of a type of socket conveniently employed with this construction; Fig. 8 is an elevation partly in section of an alternative form of holding-means; Figs. 9 and 10 are an elevation in section and plan, respectively,' of the alternative form of post shown in Fig. 8; and Figs. 11 and 12 are an elevation and plan, respectively, of the socket coopcrating therewith. I
In the construction shown in Figs. lto 7, inclusive, a socket 26'of generally triangular formation is inserted and assembled withina wood heel base 22. Cooperating therewith. is a tubular post 24 of similar cross-section, having holding lugs 25 engaging with and clinching a lift of rubber or leather 28. The tubular post is provided with lengthwise slot 353 through which protrudes a bent spring 32,, as indicated particularly in Fig.
1932,: Serial No- 631,172
4. This spring is designed to'frictionally engage with the wall of thesocket when the post is inserted therein and immovably retain the post in assembledrelation during" wear. 7 I
For the pi1rposelof=yirtually locking the post inassembled relation with the socket and to effectually preclude accidental loosening or dis-- lodgment of the lift, the-socket, as indicated at 34, may be provided with alengthwise slot or groove into which the spring 32 expands when the post is forced completely home within the socket. This. construction not onlyserves to maintain close frictional engagement between the post- :and socket,'but serves to locate the post therewithinin a simple andinexpensive manner Obviously, the shape of the spring may be altered and the holding groove on the socket changed without departing from the spirit of the invention. Actually the formation of a shoulder upon thesocket in any suitable manner with which the spring may engage when the post is completely located, should suflice for the proper maintenance of the post in assembled relation. In the form of the invention shown in Figs. 8 to 12, inclusive, the socket may be'made' of generally circular cross-section, as shown at 40,'which simplifies its application to the wood heel base 42. K
I Cooperating with; the socket is a' circular post 44, having oppositely disposed slots 46 through which aperture the opposite bowed portions of a spring lB'ar'e assembled with the post, which atits outer with respect to the socket and surrounding heel base.
Thisconstruction has the virtue that the socket may be simply made and inserted within the wood heel base, and the cooperating post may be readily inserted and removed from the socket with .Qthe assurance that it is located in a predetermined position with respect to the socket when assembled therewith- What is claimed is:
1. An attachment for nee-1 lifts or] the like comprising a'hollowsocket assembled within a heel base, a cooperating post adapted for insertion within the socket and having a lengthwise opening in the side, a spring projecting from the opening in the post for 'frictionally engaging with the socket to retain the post in assembled relattion, and means for maintaining a predetermined angular relationship between the post and socket. v 7 I tion having oppositely disposed and lengthwise positioning grooves, a, post adapted for insertion within the socket, a. spring assembled with the post and having projecting portions adapted to engagewith the socket at the positioning grooves to locate the post and frictionally hold the same within the socket.
