,According .to another 'feature of thevinvention,

the bars ror knives -.a rev secured to. .the Zplug' by means i. which interlock u with .c'ircumferentially extending 4 bands that "are formed l hyrwindings} of wire .orsthe like asv distinguished from .prior .,art

According to, thewprior art} bands which are shrunk inuplacewrequire that .part oif t he conical surface .be cut. away so that the bands may be seated. A' band expands onlys'li'ghtly uponiheat I sing, hence'it isnecessary. to out acy-lindricjal surface. intothe conical suriaceoflthegplug for each ".bandiseat andfthis .takes away some of the desirable support for LtheIbars. According tothis invention only. sufficient lengthinithe pluglis cut away for the band itselfl was, the band .is formed in the groove provided,forlitvsothatlthe construction provides almost continuous zfull idepth supportfor the bar.

a n i r' a "22 s.disp d,ar ndtheiiero y "ous A wire or'wire 24 are served aroundthel and [22.

The windingsjmayfbe ap- "p i' "s l a o ,on an 'number i y e "inn bands which' are disposed in the gro'oves.

"' ilt' is desirable that the wire be wound on the band 'under tension' sothat the-wire iayers are "verytight and'taut and form a'strong'rigidiba'nd.

The'outer end'of a wire may be secured to an'adjac'e'nti wire by welding, brazing; solderin Or. .the

like 'a's 'atfilll. It is' a well known fact that. Wire "is one of "the'strongest forms in which metal may ';be prepared and since itis applied under tension therelisproduced a bandthatlis exceptionally strong and exceptionally tight-both characteristios of which area-desirable,to;,-hold; the -igbars ffirmlyrintheir sea-ts.

' braced therein. What it is desired to claim and secure by Letters Patent of the United States is:

In the form of the invention shown in Fig. 4, an inner band 30 is wrapped around in a groove similarly to the band 22 and a thin strip of metal is served around said band 30 in layers 32 with the final end secured in any convenient manner such as mentioned above.

It is desired that the banding fit snugly in the grooves to obviate shifting thereof axially of the body and such material for the wire or strip binding may be employed as will provide the desired strength and rigidity of band.

The knives or bars I2 and M are formed on.

their lower edges with upwardly extending slots 34 providing lips or tongues 36, as shown in Figs. 2 and 4.

In assembling the bars and plug the long bars 12 are inserted in their respective slots so that the bands 20 pass upwardly into the slots 34 on the lower edges of the bars, the said lower edges resting on the bottoms of the slots 8. The bars are moved towards the large end of the plug whereby the lips 36 engage beneath the bands. The lips move the bars towards the bottoms of the slots with more or less of a cam action and hold and prevent radial displacement of the bars relative to their slots.

An end cap 40 fitting over the small end of the plug abutsjthe ends of the bars l2 and'is held in placeby screw means indicated by 42. This is a desired construction inasmuch as it covers up the end of the plug and the end of the bars and protects the end of the wood spacers. However, for the purposes of construction this cap imay be omitted and in its place an ordinary shrink ring may be used.

An end plate 38 is secured to the large end of the plug by any convenient means and may take any form desired.

Filler members 44 of wood are inserted between the bars and the short bars M are inserted in their slots and moved rearwardly for the action of the lips 36. Then blocking members 46 are inserted to prevent cndwise movement of said bars I4. Finally filler members 48 are inserted. .The filler members are driven inwardly from the large end of the plug so that grooves in the sides thereof receive spurs 48' on opposite sides of the bars.

The invention may be embodied in other spe- L cific forms without departing from the essential characteristics thereof. Hence, the present 'embodiments are therefore to be considered in all respects merely as being illustrative and not as being restrictive, the scope'of the invention being indicated by the appended claims rather than by the foregoing description, and all modifications and variations as fall within the meaning and purview and range of equivalency of the appended. claims are therefore intended to be em- I.
