v To all whom it may concern:

Be it known that I, ALFRED HANNAEORD,

a citizen ofthe Unid States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Overhead Carriers, of which the following is a specification.

Th's invention relates to an im roved construction of overhead carriers or packing houses. y

The object of the invention is to produce a cheaper, and more com act'construction of trackways, and one whic will not require so much power to be expended in driving the carriage. I accomplish this object by dispensing with the usual twoart hangers customarily employed in suc constructions, and combining the chain carrier or track and the load carrier or track in one structure, land placing the load carrier track directly beneath the chain for driving the load, whereby the pull is directly in line with the load.

The invention further consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described.

In the accompanying drawing, which forms a part of this speciiicationfFigure 1 is a side elevation ofa single section of the improved carrier apparatus. Fig. 2 is a vertical section on line 2-2 of Fig. 1. Fig. 3 is a similar section showing the return carrier for carrying the empty chain back. Fig. 4 is a sectional side elevation of the, chain, and Fig.

5 is a plan view of the chain and its track.

In the accompanying drawing 10 represents an ordinary overhead beam, either one of the beams of the ceiling work, of the packtion of this hanger is such that the chainway track su/ port is in close juxtaposition to the overhea beam, and consequently the chainway track, presently to be described, is in any leverage unnecessarily.

like manner close to the beam, and the strain of the chain upon the bolts that support the hangers from thel beam is not multiplied -by Two parallel trackf'bars 14, 14, are bolted bybolts 15 to the hangers 11, for the'chain to run upon.

s beam or these beams at short,

.'hook.

To the carrier track sup orts 13 is bolted the single bar carrier trac 16, upon which the load is carried. It will be noted that the construction is such that this carrier track bar 16 comes directly under. the center of the 6o lchain so that the pull of the latter upon the load suspended on this track bar is a straight packing house carrier systems, is entirely 6 5 done'away with. This is a matter of very considerable consequence .as the loads consisting of carcasses or parts ofcarcasses, are

often very heavy, and not only is the 'power vrequired of some importance but the Wear and tear and racking strains due to side drafts are still more important, affecting the life or duration of the mechanism. Secured to the chain at suitable intervals-say two linksv apart-are the riding shoes, each consisting of an upper plate 17 and a lower platev 18. The u per late rests and slides upon the paralle tracks 14, andthe lower p ate guards against upward displacement.,

From the lower plate dependsl a dog or engagement iinger 19 to engage the upper part of the rolling meat-hook hanger,l presently to be described. This finger may be rigidly connected to the shoe 18 but I prefer that it shall be pivoted thereto to act ratchet-fashion. The advantage of having the'iinger l pivoted to act ratchet-fashion is that where` from `accident or other cause the driving chain stops if thefmger is ratchet-like in its action the rolling hook hangers can be run on by hand without said iinger offering any obstruction.

` To strengthen and stiiien the structure I apply to the hangers 11,- 'above and parallel with the *trackI 16,'a`strengthening member 20, consisting .ota flat bar or plate bolted with bolts 21, 21", to the hangers 11. produces a very rigid and strong construction, and relatively acheap one. The rolling 7 hook hanger is shown at 22, and carries in a` loop at the upper end the grooved wheel 2 3 which ridesvupon the track 16, and carries at its lower'end immediately below, and in line v with thejwheel, the swiveled meat hook 24.

The looped upper end of this hanger serves as a .point of contact for the driving iinger 19, indirect line with the Wheel and the meat This At Fig. 3 is shown the hanger for thereturn ply ofthe chain. Itis constructed in all tion of that hanger for supporting the load carrying track is emitted, and is of course 5 unnecessary unless it be desired to carry the rolling meat hook hangers back, a thing generally done otherwise is practice.

it will be understood that the pivots of the carrying chain arel all verticall pivots, and therefore adapted to pass around horizontal sprocket wheels. And as the'load, track and rolling meat hook hanger are at all times immediatel'y beneath the chain and engaged by a depending `ringer, as contradistinguished i 5 from the' usual laterally extending engagement means, it is possible with my apparatus tocon''l'uct the carrier system in any direction, turning either-to the right or to the left as the circumstances and .convenience of the situation might demand in the packing house. This has not beenpos'sible with the ordinary averhead carrier systems wherein the carry ing chain and the load carrying track are placed side by side, and the engagement means consists of a laterally extending finger.
