CHARLES C. MCINTOSH, DECEASED, LATE 0F PORTLAND, OREGON, BY MARGARET MOINTOSH, ADMINISTRATRIX, OE "PORTLAND, OREGON.

C'QNVEYER. MEANS FOR EXHAUST OR COOK BOXES.

To all whom it may concern Be it known that CHARLES C. McINrosH, deceased, late a citizen of the United States, and resident of the city of Portland, Multnomah county, State of Oregon, did invent a certain new and useful Improvement 111 Conveyer Means for Exhaust or Cook Boxes, of which the following is a speclfication.

This invention relates in a general way to the so-called exhaust box or cooker used 1n canneries, through which the cans are run for a definite period, and has partlcularly to do with the means for conveying the cans through the exhaust box One of the objects of this lnvention is to provide simple and positive can-conveyingmeans operating in a horizontal plane.

To this end the improvement comprises a plurality of trackways arranged side by side, cooperative advancing means for each trackway, and other advancmg means connecting the ends of the ad acent trackways for carrying the can'from one trackway to the other, and thus through the exhaust box. A short-cut conveying means is provlded whereby the time required for carrying the cans .through the box is shortened without Fig. 1 is another fragmental view showing a detail of construction concerning a removable rail located at the inlet end of the exhaust box. this rail being shown in broken lines of Fig. 1; Fig. 2 is a vertical section taken on the line 22 of Fig. 1; Fig. 3 is a larger sized detail of a preferred type ofan endless screw used as the conveyor, and

illustrates the mode in whichthe cans are advanced along a trackway; Fig. 4 is a sectional end elevation of the parts shown in Fig. 3, showing in addition the rails of the trackway over which the cans are moved by the conveyor means; Fig. 5 is-a fragmental front elevation of the machine, showing the Specification of Letters Patent.

Application filed March 24, 1914.. Serial No. 827,005.

indicator element and the handle of the means provided for moving the rails of the trackways closer together and farther apart so as to receive cans of difierent sizes; Fig. 6 is a diagrammatic view showing the means employed by me for so supporting the rails of the trackways as to rende them laterally movable; and Fig. 7 is a larger-sized sectional View showing a portion of the screw conveyer running lengthwise of the trackway, one of the transverse screw conveyers connecting the ends of adjacent trackways, and the adjustable guide cooperating with said transverse screw conveyer.

' The device comprises a box or housing, a, mounted on the supporting base legs I). A number of transverse frame members, d, having legs a? and cross beams 03 are mounted on the floor, 0, of the box. The cross beams d support the can conveyer mechanism, while underneath and on the sides are the steam pipes e.

The can-conveying means consist of a plurality of trackways, f, arranged side by side, each having two rails f, f. The can is advanced along the trackway by a screw conveyer g, the thread g of which is preferably made square-face so as to be adapted for engaging the crimped edge at the bottom of the cans h, as illustrated in Figs. 3 and 4.

'The screw conveyors are driven through a motion-transmitting element 2', and the connecting pinion elements j, k.

In order to adapt the trackways f to receive cans of different sizes, the rails of the trackway are so arranged as to be laterally movable. For this purpose I prefer the ar-' rangement more clearly illustrated in Figs.

1, 2 and 6. Z, m are two transversely sliding bars supported in bearings n mounted on the cross beams d Each sliding bar carries the chairs Z, m, of one rail of the trackway. On the bottom of these chairs Z, m are secured angle rails f. and at the top of said chairs are fastened side rails 72".

Each slide bar is provided on its lower edge with a rack portion, as indicated at 12 and m in Fig. 6. Supported on the lower side of the cross beams d of the frame member d are bearings (Z for the two parallel adjusting shafts p, g. Said shafts have pinned on them the pinions p, g, which mesh with said rack portions 12, m On the extreme end of the shafts p, q are the pinions 11 9 (see Figs. 1 and 5) which mesh with each other. Fixed on the end of the shaft 10, outside of the cook box, 1s an adjusting lever 72 the transverse conveyer (1") will lie in the same plane it is necessary to make the transverse screw conveyers of greater dlameter. The transverse screw conveyers are con stantly driven by the motion conveying element 11 by the gears r r See Fig. 1. Bolted on the cross beams of the endframe members are the fixed Zplates 8. See detail Fig. 7. Parallel to the shafts r and on a shaft t are journaled the arms t for adjusting the. transverse guides. The latter carries a number of guide rails t, F, t which are located in varying levels; and the surfaces of these guide rails are so inclined that by the rotation of the arm t about the shaft t they may be arranged to lie in horizontal plane. The means for adjusting the arm 25 are shown in Fig. 1*. An eccentric stop-lug u is rotatably mounted on a pin u inside of the steam box, and the lever t fixed on the shaft 25*," is supported in place by this stop. As the arm 23 has three positions, the stop lug u is made with three differentlylocated flat faces, each arranged to so hold the lever arm t as to' bring either of the three surfaces i t of the guide rails into active position. These guide rails are provided only at that side of the screw conveyers 1" toward which they turn, since the can would have a tendency to run off on such side only.

As designed, the time elapsing between the inlet and outlet of the cans from the box would be about five minutes; but there is also provided means by which this time may be cut down without making any change in the speed of the machine. Said means consist of a short out, by which the travel of the can along'tw adjace'nt trackways is el mlnated. For thispurpose a removable rail section f is provided in one rail 7 (see Figsl 1 This removable rail section has A set screw f, sliding on a bar 7, holds the removable 'rail on its ower end an ear f section in place. When it is desired that the cans traverse all of the trackways, this removable rail section f lis placed in the posit on shown in Fig. 1 and shown in broken outline in Fig. 1; and when it is desired to eliminate the travel of the cans over the first two trackways, the rail section f is removed. In this way when the can has reached the first transverse screw conveyer indicated by A in Fig. 1, the can will be shunted directly over to the middle trackway, and then be carried up and down the trackways.

What is claimed:

1. In a device of thecharacter described,

in combination with conveying means, a

trackway comprising parallel slide-bars movable transversely to the length of the trackway, chairs for one rail of the trackwaycarried by each slide bar, angle rails fastened on the bottom of the chairs and side rails fastened to the top of the chairs, and means for moving the slide bars simultaneously in opposite directions.

2. In a device of the character described, in combination with conveying means, a trackway comprising parallel slide bars movable transversely to the length of the trackway, chairs for one rail of the trackway carried by each slide bar, angle rails fastened on the bottom of the chairs and side railsfastened .to the top of the chairs, rack-portions at the bottom of each slide bar, pinions meshing with said rack portions, and means for simultaneously rotating the pinions.

3. In a device of the character described, the combination of a plurality of parallel conveyers, guide rails at the sides of and separating such conveyers, the guide rail separating adjacent conveyers being made with a removable section located intermediate its ends, and an auxiliary transverse conveyer located at such removable section, whereby, when the latter is removed, the article carried between the guide rails of one conveyer is shunted to the adjacent conveyer.
