original No. 1,359,499, dated November 23, 12.320. seriafNo. zsazs, fued riareh si, i919. Animation ror-l reissue filed January 23,
To all whom z't may concern.:
Be it known that I, EDWARD GRUBER, a citizen of the United States, residing at' Lyndhurst, in the county of Cuyahoga and State of Ohio, have invented a certain new anduseful Improvement in Units'for Track Belts, of which-the following is a full, clear, and exact description. vThis invention is an improvement upon the track unit 'or link which is shown and described in the Patent 1,317,896 to E. H. Savage, issued October 7, 1919, the principal object being to increase the strength and durabilit of the link sides of said unit, and to diminish thel chance that the horizontal flanges at the u per edges of said link sides, which serve as aring surfaces orrail tops for the truck wheels shall be so' mutilated and deformed in usethat they cannotsatisfactor-ily serve the purposeforjvhich they are provided,
HThe invention consists in the combination of parts shown in the drawingand hereinafter described, as definitely pointed out in In the drawing, Figure 1 is a plan vi'ew of a track unit 'embodying the invention; Fig. 2 .is a sectional planview; Fig.` 3 is a longitudinal central vertical section, and.- Fig. 4 is a rear end view of said unit; Fig. 5 is a plan'view of a. modified construction;
I i .Fig 6 is a side elevation thereof, and Fig. 7
is a front elevation partly broken away and sectioned. v 4
The link comprises three members, viz: the middle member A and the two side members B and C, all made from metal sheets bent into the `forms shown and secured togeth'er. The middle memberA has the form of a substantially square U', and is soformed. b bending up the sides of the metal plate,' tlihreby producing the flat bottomor shoe portion l2, and the two vertical longitui' dinally extended rails 13.
The two side members B and C are alike except that theysare'ri hts and lefts. .Each has a `vertical longitu inally extended rail 21; andmay nave a horizontal shoe portion 22, of which the rail is an integral part, as shown in Fig. 4; or it may not as shown in Figs. 5. to 7. These rails are so shaped that when the three pieces are laced side by side the rails 13 and 21 will) be in contact near the front end of the unit, and near the 1922.` Serial No. 531,270.
rear endY of the unit; but the parts of the rails between Said contacting front and rear ends are :spaced aI art.V This results .from` the fact Ythatftlie.rails 13 near their rear ends are offsetapart; andthe rails 21Anear their front ends V'a1-je offset toward one another.4
The offset portions are, however, parallel with each other'a-nd withthe rails from which coV4 they are offset. When the rails are placed' i together as stated, the offset front ends of the rails 21 engage with the outer, faces of the front ends of the rails 13 and are connected Awith thm by'tspot welding, rivets and the like. The offset rear ends of the rails 1 3 will likewise engage the inner faces of the rails 21, and these engagin parts are connected together by spot wel ing, rivets or the like. v -v The offset parts of said rails at the front and rear ends of the unit, together with the parts ofthe rails which contactwith and are secured to said offset parts constitutedouble thick ears. These ears at the rear ends of L l the unit are farther apart than those at the front endof the unit; and therefore the ears at the front end of the unit may go between the ears at the rear end of the adjacent unit; and the overlapping ears maybe pivoted togetherv by =any suitable or well known means. Y
The part of one rail: which -is spaced away from the associated rail is formed with a turned over horizontal-fiange 24 along its upper edge which fiange extends over and rests upon a Apart` of 'the companion rail.
VPreferably the flanges 24 are on and parts ofthe rail 21; and preferably also the rails 13 have each a recess 16 cut out of its upper edge into which a flange 24 is fitted, so that the upper surface of the said fiange is flush with the upper edge of the rail 13.
These flanges form strong, well braced, broad surfaces for the track wheels to ride onand they are so constructed and sup- 4ported that there is practically no chance that' they will become deformed by use to `al1 extent such as will render them inefficient for thepurpose vfor which they are provided.
In vthe construction shown a shoe 30 is i provided.- This is a flat metal plate whose side edges are coincident with the side edges of the shoe portions of the members B and C, and these shoe portions of said members f. Figs. io-
as does the middle por- The shoe is secured bolts, rivets rest vupon the shoe tion of the member A. tc these,V parts by'shot Welding, or the like. i
The front' edge of this attached shoe may be turned down to form the 'ground engag ing ribyor grouser 31. y i
In the modified construction shown in to 7 the members B and C have no shoe portions, but are in most other respects substantially like the said members as shown in'Figs. 1 to 4 inclusive. The horizontal flanges 24 are, however, formed on .the upper edges ot' the railsfl; and these flanges rest only on the top of the offset-Web 25 of the rail 21.
i As shown in Figs. 5 to 7, thc shoe 3() is only connected with the middle member Having. described my invention, I claim: 1. A track 'belt unit comprising three metal membersl arranged side by side and connected together, viz, a middle member having along its side edges vertical longitudinally extended side rails, and two side members each having a vertical longitudinally extended rail which is secured to a rail of the middle member, the rails which are so secured together being in contact at vtheir .front and rear ends and being spaced apart between said contacting ends, the upper'V edge of one of said spaced apart rails beingr formed With a horizontal flange which overlies and engages apart of the upper edge of the associated rail.
2. A track belt unit comprising three metal members which are arranged side by side andare connected together, viz, amiddle member having along its sides vertical longitudinally extended rails which at their rear ends are otfset apart, and two-side members each having a vertical longitudinally extended rail which engages and is secured to the inner face of the offset part of a rail of the middle `member,-the rails of said side members atrtheir front end being offset toward one anotherf-said olfsetparts being in engagement with the outer faces of the associated upper edge of one of the rails of each pair of connected rails being formed with a horizontal flange which overlies and engages the upper edge of the associated rail. Y
3. A track belt unit comprising three rails ofthe middle member, they metal members arranged side by side and connected together, viz, a middle member having along its side edges vertical longitudinally extended side rails, and two side members each having a vertical longitudinally extendedrail which is secured to a rail of the middlel member, the rails which are so secured together' being in contact at their front and rear ends and being spaced apart between said contacting ends, the upper edge of one of said spaced apart rails being formed with a horizontal flange which over lies and engages the upper edge ot 'llreassociated rail, and a shoe upon which said three members are secured, which shoe has at its front end an integral dov uwardly bent and transversely extended groundengaging rib.
4l. In a track belt unit, a shoe, a central rail .member having a base secured lto said shoe and upturned sides YForming rails, and side rail members having a base secured to said shoe and upturncd sides forming rails.
5. In a track belt unit, a shoe, a' central rail member having a base secured to said shoe and upturned sides forming rails, and side rail members having a base secured to said shoe and upturned sides secured to the sides ot' said central rail member.
(i. In a track belt unit, a slice, a central rail member having upwardly extending sides secured to said shoe, and side rail members having a. base secured to said shoe and upwardly extending rails provided with bent over llanges.
7. In a track belt unit, a shoe, a central rail member having abase secured to said 4shoe and sides forming rails extending'up- Wardly, and side rail members secured to the sides ot' said central rail member and having rail flanges projecting there ['rom and supported by the sides oit said central rail member. n V i 8. In a track belt unit, a shoe, a central rail member having a basesecured to said shoe and sides extending upward therefrom forming rails the top edges thereof having recesses, and side rail members secured to said shoe having flanges bent over and supported Within the lrecesses in the top edges of the sidesot said central rail member.
