CARRIER.

SPECIFICATION forming part of Letters Patent No. 374,477, dated December 6, 1887.

Application tiled August 25, 1887.` Serial No. 247,864. (No model.)

To all whom, it may concern:

Be it known that I, JOSEPH A. JEFFREY, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Carriers, of which the fo`1- lowing is a specification, reference being had therein to the accompanying drawings.

Figure lis a plan view of my improvement in ahorizontal position. Fig. 2 is a front view in a vertical position. Fig. 3 is a section of Fig. 2 on line 3 3. Figs. 3*l and 4t are detached views enlarged. Figs. 5 and 6 are detached views enlarged, showing a modification of parts of the structure. Fig. 7 is an enlarged section on line a: E, Fig. 3, of so much of the chain as is necessary to illustrate its structure at that point.

Like letters refer to like parts in all the iigures.

The object of my invention is to construct an improved carrier which shall be adapted for the transportation of various articles in horizontal or vertical planes, or planes which are slightly inclined, the construction of parts being such that the direction of travel of the carriers can be changed from a horizontal plane to a vertical plane without undue strain upon any of the parts.

The chain which I propose to use in the carrying out of my invention is preferably composed of separable side bars, A B, C D, of which the vparts B D are inwardprojecting thimbles or sleeves, the opposite ends of the side bars having seats c c to receive a pintle, E, which also passes through the sleeves B D, thus tying the side bar-s together into a chain.

F F are anti-friction rollers mounted on the sleeves.

The pintles are by preference locked in their seats a c, so as to be incapable of movement therein, whereby the Wear is transferred to that part of each pintle which is seated in its adjacent sleeves B D.

One side bar of cach pair of links or of each second, third, or fourth pair, as may be desired, is provided with ears b b, projecting at right angles from the side bar and upon opposite sides thereof.

G is asocket or box, preferably angular in cross section, and provided upon its longer side with outward-projecting ears g g of such v length that the holes g' therein will register with holes b in the ears b of the side bar, to receive bolts or rivets d, whereby these parts may be firmly united to each other, but can be easily separated by taking out either the rivets or the screws, as the case may be. `II H are carrierslats or supporting-slats, having their endsseated in the boxes G G, to which they may be further secured by pins h h, passing through the slats and the sides of the boxes, (one or more sides of each box.)

In Figs. 5 and 6 I have shown a modifica tion adapted to carry articles in vertical planes or planes which are slightly inclined to the Vertical. In Fig. 5 I have omitted the boxes, and have bolted the ends of the carrier-slats directly to the ears bzbwhich in this instance project at right angles from their respective side bars and upon both sides of the bars. Some ofthe advantages arising from my in vention are incident to both constructions. For instance, it will be observed that the connections between the carrier-slats and the side bars of the chains are wholly upon one side of their respective chains, and do not, therefore, in any manner interfere with a proper engage` ment of the sprocket-wheel teeth with the links of the chain; nor do they interfere with a satisfactory running of the anti-friction rollers during their engagement with the sprocketwheels and a supportingtrack, l,which is frequently employed to support the weight of the carrier when traveling on horizontal or inclined lines. Again, the combination of these carrier-slats, the ears, the side bars, and fastening devices, which connect these parts together with greatl firmness and rigidity, prac; tically prevent all sidewise swaying of the chain between its supporting-wheels, and thus insures that the carrier will run with a minimum of friction and wear and tear upon the sprocket-wheel and also upon its supportingtracks. Again, the use of twoV ears to each side bar, projecting upon opposite sides of the `side bar, insures a great uniformity in the working strain upon the articulations of thev links, especially when the carrier is changing its direction of travel. i

The construction shown in Fig. 5 is particularly advantageous, from the fact that the bolt- ICO ing ofthe side bars at tWo points7 b3 b3, to each' end of the carrier-Slat practically insures that the pintles and anti-friction rollers of those bolted links shall be at all tinies kept in the same plane relatively to the slat and the parts of the sprocketwheels which the5T are traverslng7 thus guarding,` against unequal wearo' the articulation or thebearing-surfaces o' tl e rollers and their inelosed sleeves.

Wherever in this specification l have used the words above and below the bars I refer to the fact that the ears b l) project both above land below their respective side bars when the chain is arranged in a horizontal plane; and it will be seen that in both constrnuetions the ears project from the inner and adj acont side bars of the two parallel lines ot' chains, the outer side bars of the chains having no ears projecting` from them.

What I claim isl. Ina carrier, the combination of the outer side bars, the inner side bars provided with oppositely-proiecting ears, the pintles, the anti-friction rollers, and the carrierslats eonnected to the oppositelyprojeeting ears, sub- Stantially as set forth.

2. In a carrier, the combination7 with the carrier-slats, of the chain-linlrshavingthe 0ppositely-projecting ears, and the boxes connected to the ears and having,` the ends of the carrier-slats attached thereto, substantially as set forth.

S. In a carrier, two parallel lines of chains provided upon their adjacent sides with oppositelyprojeeting ears, and the carrier-slats shorter than the distance between the chains and having their ends secured to the ears upon both the upper and lower sides of the chains, substantially as set forth.

et. 'In a carrier7 the combination of the carrier -slats and two parallel lines of endless chains provided upon their inner faces with botes receiving` and supporting the ends of the carrier-slats. sulisl'antially as set forth.

ln testimony whereof I allif :nysignature in presence of two witnesses.

JOSEPH A. JEFFREY.
