Specifieation'nf Letters Patent. P t t d p 235E155 Application filed October 8,-1914. Serial uas'esjzz'z.
T auto/ 10m it may (on-corn Be itknownthat I, SAMUEL J. HARRIS, acitizen of the United States, resident of Stoughton, in the county of' Norfol'l't' and ;::State-of ="i\ ass'ach'use tts, have made-a certain" new" and useful Invention in Fri'etion and Metal .1 Plugs for Rubber"Heels,-" &e.; and I declare the followingto be aful'l, clear, and exact=-description of the same, such as will :enable: others skilled in" the art to which it appertainsto make and use the invention, reference-beinghad to the accompanyingdrawings,- and toletters or figuresofre-ferencemarked thereon; which form-a part'of this"- specification Figure l is abottom planwiew'of'a rubber heelhaving my invention applied thereto-(- FigJ-J2 is a top plan view-of :thewv'ear 'lift of the heel having the invention applied thereto; Fig. 3 is-a' section on 'the line-'3-f-3, Fig.-
1. Fig. 4 is a detail bottom plan viewof themetal frame plate" and 'posts, \vith' a canvas plug in engagementwith= one of the posts.
' Fig: 5 isa detail side viewofth'e' same. Fig.
.ZG-isa detail bottom-plan "iew of'a modification-of the metal frame plater The invention-has relation'-*to means for reducing: wear upon" and preventing slip page; of rubber: heels and other treadi'sur faces, having; for its object 'theprovision-"of a friction and" metal plug "therefor, and it consists in the novel construction' 'and"coup bination's of'devices, as hereinafter setforth;
Inthe 'aecomp'a' nyingrd aw-ingsfillustra t ing: the invention as app'li'ed to a; rubberheel the numeral 2 indicates the topor 'we'a'r'lift' of -the heel, which in use formsthe-liottom of'the heel, and 3 the'lift neXt-toit, other lifts being sometimes employed; according -torequirement, these lifts forming-"-when' compressed together and finished, as hereinafter'described, the-rubber heel.
In the nianufa'ct'm'e,after the rubber compound-has been properly'- calender'ed and 45 rou'glit into sheet form, the heel-lifts are cutout'witl-i a die, and are'ready'to be built into-the heel; ln'this construction, a metal frameis providcd'havinga flatbase 4, and projecting from this base hollow posts '5 of' 50 'substantially tubular form but usual'ly of spliteharacter and having separated arms 6, between-whichare intervals 7. The hollow ofthe postextends throughthe base'by a perforati(m'=-8,for the p'assage'of a fastening nail 9,-th'ehead'of which'may be driven home *in the-post against-"the base. Each post is substantially cylindrical, butthe armsfi mavhave some flexibility, sdthat they may "be slightly pressed toward the axis of the post, to provide fora slight ta-pei so toward itslencl portion. Each post i"' dsigned to be encircled'with a packiil or plug offrictionized canvas or other 'siiitable' material, rolled into a spool of suflicient'di ameter and length and having a. hollow ter'to-recei\-'e the frame post, which it is-'designed to hug firmly. Each-frame'iis pro-' vided with a suitable numberof these posts? The top lift or Wear lift 2 of theheel'hav? I"10:
ing'been tapped to provide-holes12' for 'th posts and their plugs, the frame is 'ap pfl thereto, the postsand plugs beingfoi'ce into the holes, which may be made slightly smaller in'diameter than the plug's',-so that the plugs will-be closely enga gedf'by"theta holes. The frame base engages the-inner surface'or that surface of thetop lift which isrdesigned to be joined to the next lift, 3,- of'the' heel, which is cemented and joined to the lift 2, the'ceinent'eoveringvin.thefr ainef' base; Theselifts and the intermediate" frame are placed in -a mold and compressed and vulcanized, so that they provide a-solid' heel, in which the "posts and plugs'havv" I their ends-substantially flush with or a little' below the \vear'sui'faee of thelift 2. In the construction, the-frame-is placed in the rear; portion of-the heel, or near its back, and is". designed to toughei'i. and strengthen the same, serving an important purpose in reventing the heel from running down in use, and' in" guarding against slipping. When theposts and their plugs are forced into theholes of the heel", the pressure is designed to be sufficient to bend the arms-off the post slightly inward, or tow'ard the axisof'the'hollow of'the post, so' that the plug? assumes a slight taper. In thiscase, the arms may be separated 'sufliciently for the introductionof the fastening nail, and after the-latter has been driven home and the p driving punch withdrawn, the arms will as? T sume their inclined relation, more or less," thereby restoring th'e'taper relation and pre-- venting the plug from coming out of its seat 1105 in the lift. The vulcanization ivill cementf and connect the twoheel lifts and secure the." metal frame plate between said lifts, and will at the same time cement thepacking; plugs to the lower lift and form a unitary 119 article; In. Fig. 6 of the drawing a modification is shown wherein the frame plate is extended,
usually' to accord with the heel contour and take the place of the washers commonly employed betai'leen the heel lifts fo'r the fasteningnails. l
What I claim is:
1,- An attachment for rubber heels and "other tread surfaces, comprising metal frame plate provided with a post extension, and a plug pf rubber-coated material surrounding said, post, said frame plate extending across and having bracing engagement with the top of said plug.
2. An attachment for rubber heels and other tread surfaces, comprising a metal frame plate provided with a compressible post extension,-anda compressible plug of rubber-coated material surrounding said post. t
