(01. 306-33) My invention relates to a wedge and I declare the following to be a full, clear, concise and eXact description thereof. suf?cient to enable anyone skilled in the art to which it appertains to 5 make and use the same, reference being had to the accompanying drawing in which like reference characters refer to like parts throughout the speci?cation. The object of the invention is to provide a 10 wedge for use more. particularly in securing hammer or axe heads to their respective handles. bottom edge 3 toward the top surface 2. The taper, however, is acute at about midway between the bottom edge 3 and‘ top surface 2, whereby said wings 5, 5 disappear or terminate at said central locations. By thus terminating wings 5, 5 5 below the top surface 2 of portion I said wings 5, 5 will disappear in wood ll of the handle l2 when driven home therein to secure the head Hi to said handle I2. Furthermore, the taper of central portion l 10 from its top surface 2 toward its bottom edge The shock incident to the use of the aforesaid 3 will cause the openings in the grain of the wood tools has caused the wedges heretofore used to work loose and thereby allow the head of the H of handle l2, made by the entrance of said wings 5, 5 into handle l2, to be closed behind 15 hammer or of the axe to separate from its handle and this perhaps at a time when the hammer or axe is being swung to drive home a nail or in the case of the axe to split wood with accompanying fatalities. The present Wedge over20 comes these difficulties as will be seen from the drawing in which ‘ Fig. 1 is a perspective view somewhat enlarged showing the wedge. them as they disappear below the upper surface 15 it‘ of the end of handle l2. This disappearance of the wings 5, 5 into the Wood H of handle ii and the closing of the openings behind them positively locks the wedge l into the grain of said wood ll within the eye or opening I‘! of the tool 20 l8, whereby the shock incident to the use of the tool It will not allow the wedge I to work loose and fall out. Fig. 2 is a perspective view somewhat enlarged , Furthermore, Wings 5, 5 although Spaced are 25 showing the wedge tipped on one side, inclined or tapered laterally towards the respec- 25 Fig. 3 is a perspective view showing the wedge tive sides of portion l as above stated, whereby as it appears from the lower end. to effect inclosing members into which the por Fig. 4 is a plan view showing a pattern before tions of the wood ll of handle it are driven being bent into shape. and. inclosed, ' 30 ‘Fig. 5 is a vertical section taken onv the line This latter iHOIOSIII'B feature and timer has 30 5-—5 of Fig. 1, _ ' Fig. 6 is a plan View looking down on the top of the wedge. Fig. 7 is a plan view looking in the opposite 35 direction from that of Fig.6. Fig. Bis a perspective view of ahammer broken away and showing the wedge applied‘ thereto. Referring more particularly to the invention, the wedge consists of a rectangular portion I that 40 tapers from its top surface 2 towards its bot- , tom edge 3 in cross section. There is formed integral however, on the opposite sides of the rectangular portion l and. at its opposite lateral edges, wings 5, 5 by curving the extended part 45 of rectangular central portion l at its opposite lateral edges 6, 6 and in dilierent directions, around back upon itself to form additional retaining surfaces. However, each of the wings 5 is spaced from the adjacent surface of central por- 50 tion I. . These curved portlons 5, 5 do not lay quite parallel Wlth the contiguous opposite lateral surfaces of portion l but incline or taper at their _ free ends H], In towards said respective surfaces. 05 Moreover. said wines 5. 5 also taper from the the added advantage of effecting a lateral wedge on either side of central portion I. These lateral wedges function as the Wedge is driven into posi tion into that portion of wood ll of . handle I2 within eye ll of tool l8 which causes the free 35 points of wings 5, 5 to be forced outwardly thus effecting lateral Wedges on opposite sides of part ' l in addition to the wed‘gl'ng 0f Said Central Por tion I. As a further means of holding wedge I into 40 position when driven home into that portion of wood ll of handle l2 within eye ll of tool Is, the free edges of wings 5, 5 are notched or formed with barbs 20 which slide easily into wood I l of handle IE but do not allow said wedge l to be 45 pulled out of said handle l2. Having thus described my invention what I claim as new and desire to secure by Letters Pat ent is as follows: 1. In a wedge, a central portion tapered from one end to the other, wings formed on said cen tral portion, said wings terminating midway be tween the upper and 10wer edges or the wedge and disposed on opposite sides thereof, whereby to effect additional retaining members. ' 55 2,078,875 2 2. In a wedge, a central portion tapered from one end to the other, Wings formed on opposite sides of said tapered portion and at opposite ends thereof said wings tapering towards said central portion and said wings terminating midway be tween the upper and lower edges of the Wedge, whereby to effect additional wedging functions. 3. In a wedge having a central portion that tapers in cross section from one end to the other, wing members formed on said central portion, 10 said wing members lying in spaced relation to said central portion and tapering towards the same and said wings terminating midway be tween the upper and lower edges‘ of the Wedge, whereby to form pockets to effect additional 15 Wedging functions. 7 4. In a wedge, a central portion tapered in cross section from one end to the other, wings formed on opposite ends of said central portion, said wings lying in spaced relation to said cen 20 tral portion, barbs formed on said wings, to aid in holding them in predetermined position and said wings terminating midway between the up per and lower edges of the wedge, whereby they disappear when the wedge is assembled. 5. In a wedge, a central portion tapered from one end to the other, wings formed on oppo site sides of said tapered portion, whereby to effect additional wedging surfaces, said wings terminating midway between the upper and lower edges of the wedge, andv notches formed on said Wings to aid in holding them in predetermined 10 position. 6. In a wedge, a central portion tapered in cross section from one end to the other, Wings formed on opposite ends of said central portion, said wings lying in spaced relation to said central 15 portion, barbs formed on said wings, to aid in holding them in predetermined position, and said wings terminating midway between the upper and lower edges of the wedge, whereby they 20 disappear when the Wedge is assembled.
