(o1. 19o-195) This inventionÍ relates- to` a bar conveyer chain The widthv of the notch in the offset It is sub-= which, while more particularly designed as the stantially equal to the width of the bearing loop I I` of the links, and the over-all width oi the offset is substantially equal to the spacing between the two bar loops I2 of the links. elevating chain» for potato diggers `and the like, will be found useful wherever an open bar con 5 veyer is required. The principal object of the invention is to pro vide a bar conveyer construction which will be economical to manufacture and which can be To' assemble the chain, the offsets of one of the bars I5lis slipped into the bar‘l‘oops il of a pair of links. A second pair of links is then turned up easily and quickly assembled in any desired wardly, as-shown at the right of Fig. 4, with their lengths without the use of tools; Another object of the invention is to provide a hooks t2 engaging each side of the offsetsy and are bar‘conveyer construction whichwillf be self »lock ing when assembled; long wearing; and in which then turned downwardly into alignment with` the first links. This is continued throughout the line of thev links. ‘ signed for simplicity, economy, and efficiency. When the chain is completed the links are self locking. The hooks II cannot unhook since the shoulders on the portion It strike the hooks lf2 of the adjacent link, and similarly the hooks I2' cannot unhook since they strike the shoulders of These will becomey more apparent fromV the follow« the next link. Therefore; after the chain is` once worn or broken parts can be quickly andl easily replaced while in the field. Other objects and advantages reside in- the de tail construction of the invention, which is- de ing description. ` ' ' assembled, it is securely and permanently locked. ` VIn the following detailed description of the in However, should' it be desired to remove a link or vention: reference ishadçto- the accompanying a bar, it can-be clone by turning the link at right angles to the bar and slipping the hooks from the drawing which- forms a part hereof.

' The links may be formed by drop forging or same. may be cast from malleable iron or steel. While a specific form of the improvement has The invention comprises two series of links, such as illustrated in Fig. 3. These links each comprise a main link portion IIJ carrying at one extremity been described and illustrated herein, it is de- : sired to be understood that the same may be varied, within the scope of the appended claims, a single centrally positioned bar loop II, and at its other extremity a pair of similar spaced-apart 40 bar loops I2. At the center portion of the link, between the bar loops I2, is a sprocket notch I3, containing a sprocket bearing face I4. The links are used in conjunction with a series of conveyer bars I5. The bars I5 may have any desired length, depending upon the width re quired for the complete conveyer. The bars are oiTset,v as shown at I6, adjacent each of their extremities and terminate in bear ing ends I'I which are in axial alignment with the main portion of the bar. It is preferred to employ straight, round rods for the bar I5 to form the oiTset I6 by heating the extremities of the bars and deforming them in a punch press, thus insur 55 ing that all of the offsets will be uniform. without departing from the spirit of the inven tion. Having thus described the invention, what is 40 claimed and desired secured by Letters Patent isz 1. A conveyer chain consisting of a series of bifurcated links, the furcations at each side of the bifurcation being turned back upon them selves to form a pair of hooked extremities; a single bar loop at the opposite side of said link in alignment with the bifurcation therein; and an offset bar extending through the hooked ex tremity of one link, thence extending longitudin ally of said chain between the latter hooked ex tremity and the bar loop of an adjacent link, thence extending laterally of said chain through lthe latter bar loop, thence returning longi tudinally of said chain between said latter bar 55 2 2,126,274 loop and the other hooked extremity, thence pass ing through said latter extremity to connect the adjacent links together with said bar separating the hooked extremities from the bar loops thereof. 2. A conveyer chain consisting of a series of bifurcated links, the furcations at each side of the lbifurcation being turned back upon them selves to form a pair of hooked extremities; a single bar loop at the opposite side of said link and said double bar loops engaging said bars at each side of said offset; and shoulders formed on said links to prevent the adjacent links from un hooking, all of said loops having an open side, opening in the direction of the plane of said Ul link, so that when said links are turned to a posi tion substantially at right angles with each other said loops may lbe slid from engagement with said bar and with said shoulders. in alignment with the bifurcation therein; and 5. A link for bar conveyers comprising a rela an offset bar extending through the hooked ex tively ñat body portion; a bar loop extending from the mid-portion of one side of said body tremity of one link, thence extending longi tudinally of said chain between the latter hooked extremity and the bar loop of an adjacent link, thence extending laterally of said chain through the latter bar loop, thence returning longitudi nally of said chain between said latter bar loop and the other hooked extremity, thence passing through said latter extremity to connect the ad jacent links together with said bar separatingv the hooked extremities from the bar loops thereof, the bifurcations in said links extending inwardly therein beyond the position of said bars to form openings through the links for the reception of sprocket teeth. 3. A bar conveyer comprising a series of round parallel bars; an offset formed in each bar ad jacent each extremity thereof; a series of links; a single bar loop on one side of each link; double 30 bar hooks on the other side of each link, said single bar loops being engaged in the offset por tions and said double bar loops engaging said bars at each side of said offset; and shoulders formed on said links to prevent the adjacent links from unhooking, all of said loops having an open side, opening in the direction of the plane of said link there being an opening through each of said links for the reception of sprocket teeth. 4. A bar conveyer comprising a series of paral 4.0 lel bars; an oifset formed in each bar adjacent each extremity thereof; a series of links; a single bar loop on one side of each link; double bar hooks on the other side of each link, said single bar loops being engaged in the offset portions portion; and a pair of bar loops extending from the other side of said body portion, said links being bifurcated between said pair of bar loops to form a sprocket tooth notch in said body portion. 6. A link for Ibar conveyers comprising a rela tively flat body portion; a bar loop extending from the midportion of one side of said body 20 portion; and a pair of bar loops extending from the other side of said body portion, said pair being spaced-apart a distance suilicient to allow an offset bar to pass longitudinally between the pair of bar loops and the ñrst bar loop and on ~ each side of the latter. 7. A bar conveyer comprising: a series of round parallel bars; a rectangular offset formed in each bar adjacent each extremity thereof, said oifset consisting of a short section of said bar forced ‘ to one side of the main section and connected with the main section by short lateral bends; a series of links; a single bar loop on one ex tremity of each link; a pair of spaced-apart bar loops on the other extremity of each link, said single bar loops being engaged in the offset por tions of said bars; and said pair of bar loops engaging the main portions of said bars at each side of said offset so that said bent portions will separate the single bar loops from the pair of 40 bar loops.
