IIWPROYBD HANDLE FOR "EDGE-KEYS.
The Schedule referred tain these llhe'lzters- Patent and making part of the same.
To all whom it may concern Be it known that LBwmmn A. WooDBnRRY, of Beverly, in the count-y of Essex and State of Massachusetts,haveinvented anIinprovement in the Handles of Edge-Keys, for iinishingthe Soles of Boots and Shoes, of which the following is afull, clear, and exact description, reference being had to the accompanying drawing making part of -this specification, iu which.- v lFigure l is an elevation of an edge-key, provided with a handle constructed in accordance withmy invention. Figure 2 is a longitudinal vertical section through the center of the same. Edge-keys for finishing and polishing the edge of the soles of boots and shoes require to beheatedeprevious to being used, in consequence of which the handle becomes heated bythe tang, or portion inserted therein, to such a'degree that the hand of the operator is burned and rendered callous by the constant use of the tool; furthermore, the interior of the handle is soon charred, so that the tang becomes loose, and requires to be steadied in place by means of wedges, and, after using theA tool for a short' time, a new haudle becomes necessary.'
To overcome these objections is the' object of my invention, which consists in a handle, provided with `a sleeve, the diameter of aportion of the handle being less than that of the interior of the sleeve, so as to leave an air-space between the two, which prevents the heat-of the tool from being communicated to the hand ot' the operator, as heretofore and My invention also consists in attaching the shank tothe wooden portion of the handle by means of a plate or disk and screws, whereby less heat is transmitted to the handle than heretofore, and a means is provided for readily tightening the shank in the event of its 'becoming loosened by the burning or charring of the end of the handle.
To enable others skilled in the art to understand and use my invention, I will proceed to describe theA manner in which I have carried it out.
In thesaid drawing-ll A represents the shank of the tool, whichfls provided at one end with 'a circular plate or disk, B, which is rmly secured to the end of the handle O by means of screws a.
, The handle Gis formed of hard wood, and is sur rounded for the greater portion of its length by a me tallic sleeve, D, which is slightly. bell-shaped latitsmont-h or lower end.
` The lower halt' of the wooden handle is turned down from b to c, as seen in iig. 2, so as to leave an airspace, d, which prevents the heat'which is communif' cated to the lower portion ofthe handle 0, vfrin the shank A and disk B, when the tool is ready for use, from heilig transmitted to the sleeveD, and conse-- quently all liability of the hand of Athe person using the tool being burnt or injured, as heretofore,gis cnt-irely avoided.
By attaching the shank A to the handle C n the manner above described, I am enabled to dispense with the'long tang or portion which hasheretofore been inserted within the handle, andconsequently, much less heat is communicated thereto than heretofore, while, if the shank becomes'loose in consequence of the extreme end of the handle O'heooniing burnt orcharred, it is merely necessary to'tighten the screws P.
