.To all whom it may cancer-n..-

Be it known that we, ROBERT E. ScoTT and LYMAN OLEIN STEINHQFF, of the town of Simcoe, in the county of'Norfolk, Province of Ontario, Canada, have invented certain new and useful Improvements in Continuous Steam Cookers, of which the following is a specification.

The object of our invention is to devise means for continuously carrying on the cookirg of canned goods in an economical and e cient manner; and it consists, essentially,

of one or more cylindrical steam-retorts, each bar to whic In the drawings like letters of reference mdicate corresponding parts in the different rovided with an internal helical rib and of a ongitudinally-ribb ed cylindrical carrier journaled within the cylinder and adapted by its rotation to move cans along the helical guideway formed b the helical rib, means being provided for ceding and discharging cans, substantially as hereinafter more specifically described, and then definitel claimed.

Figure 1 is an end sectiona elevation of the cooker, showing only one retort. Fig. 2 is a side sectional elevation on a small scale, showin three retorts arranged in series. Fig. 3 is a fade view of the feeder partly broken away. Fig. 4 is an enlarged detail showin the sprin -packing of the cylinder of the eeder and t e valves. Fig. 5 is a plan view showing the means employed for feeding cans to the cookers. v Fig. 6 is a sectional elevation on the line a a in Fig. '5. Fi 7 is a sectional detail showing the alr-vent 0 one of the pockets of the feeder. Fig. 8 is a perspective detail showin part of the helical r1b and the it is connected.

es. The fundamental feature of the cooker is the cylindrical retort A, suitably constructed of sheet metal.

it of T iron or steel secured to bars 4%. Thus the rib may beinserted in the retort andcarried round and round the retort alon the helical guideway formed by the helical rib B, and finally discharged through .the exit I). To force the cans around the helical uidewa with the least possibility of 'amnung, it is esirable that the ribs 0 should cross the rib B substantially at right angles thereto, as indicated in Fig. 2. Steam of course will be admitted to the retorts through any suitable pipe, such as U. 11 order to kee the cans for a sufficient length of time un er the heating influence of the steam, while retaining the capacityfor a large output, it is preferable to arrange two or more'retorts in series one above the other, the outlet of one discharging into the. inlet of the next retort in the series. (See Fig. 2.)

Suitable gearing must of course be procharge.

The feedin apparatus comprises a cylindrical casing T), communicating with the inlet a of the up er retort and provided at its upper side with an inlet-hopper E. Within the casing is journaled a c linder F, rovided with peripheral pockets each a apted to receive a can on its side. Each pocket is provided with a swing-valve H, pivoted at one side of each pocket near the periphery of the cylinder. The opposite side of the pocket is formed on an are constructed from the pivot of the swing-valve, and the end of the valve is preferably rovided with any suitable packing e, where y it may be given from one to the other and so to the final disa steam-tight contact with the curved side of v I I s in e of each swing-valve projects out.

pockets G after'the can has been discharged through the openin a, so as to force the steam out of the poo et, and thus prevent it being carried around and wasted through the inlet-hopper. To give the valves this motion and to open them again to receive the cans from the inlet-hopper, the mechanism shown 3 isprovided. It will be seen that the t ough the end of the casing and has an arm I secured thereto. Of course each spindle must be suitably acked where it comes through the end 0 the casing in order to make a steam-ti ht joint.

cam J is suitably supported on the casing in such a position as to en age each arm I as it is brought around by t e revolution of the cylinder, and thus throw the swing-valves to the ositions indicated at the lower ri ht ban in Fig. 1. Kis another cam secure to the upper part of the casing ofthe feeder and adapted to engage the arms I to cause the valves to'resume the open position toreceive the cans: As the back .of each ocket is oppn to the atmosphere, as already escribed, W

en a swing-valve is moved to shut outthe steam it merely has to overcome the steampressure and does 'not tend to form a vacuum behind itself, nor will it compress the air when moving in the contrary direction.

Any suitable mechanical means may be provided to form a steam-tight joint between the ends ofthe cylinder F and the casin D. The latter is also preferably made in ha ves secured together, as shown. Spring-packing 1' is also preferably provided in the cylinder F between the pockets G to give the cylinder a steam-tight bearing against the periphery of the casing D.

It is preferable to duplicate the valve-operating parts at each side of the feeder-casing. (See Fig. 2.) V

v The discharge is bestseen in Fig. 1. It comprises a segmental cylindrical casing L, within which is journaled a steam-tight cylinder M, provided with peripheral pockets N. The spindle 7c of this cylinder M is preferably provided with adjustable bearings, as shown, in order to take up any wear between the cylinder and the periphery of the casing. A water-pipe lfpreferably communicates with the interior 0 the segmental casing adjacent to thecommunication between the casing and Y the discharge-aperture b of the retort above it. Ordinarily \the water of condensation from the retorts will fill that portion of each pocket which is not filled by the can, and

The endof each arm I is provide with africtional roller t. Av

, machine.

thus the escape of steam will be prevented; but through the pipe I Water may be introduced into the pockets, if necessary, to supply any deficiency of. water of condensation and brin its level above the cylinder M. The spin le 7c of the discharge-cylinder will be geared to the rotary cylinders of the leto'rts, as shown in Fig. 2. On the spindle k, or any of the other s indles of the apparatus, suitable driving-pul eys maybe located.

From the construction described it follows that cans may be introduced into the apparatus without permitting the escape of steam and that the-cans may be conveyed through the apparatus in suflicient quantities to give the machine a lar e output while giving them sufficient time to ecome thoroughly cooked,

and ultimately discharged without permitting escape of steam or other loss than the water of condensation- The arrangement of the gearing shown may be widely varied without departing from the s irit of the invention.

To enab e the apparatus to cope with the output of the can-topping machine usually employed in canneries for sealing the cans,

it is preferable to employ the conveying mechanism shown in Fig. 5. In this figure, O is the endless conveyer, supposed to be bringing cans on their ends from the topping- This conveyer leads between two other endless conveyers P, each of which leads to the hopper E of a cooker.- On a suitable support adjacent to the end of the conveyer O is pivoted an arm R. From this. arm extends a short arm m, connected by the pitmann with a crank 0,-fastened on the end of the spindle p of the end drum or carrying-wheel of the endless conveyer O.

From this constructionit follows that the arm R-is reciprocated'synchronously with the movements of the-conveyer 0. .Thus the cans as brought up by the conveyer are knocked by the arm alternately to the right and left. As the arm is arranged to strike near the top of the can, it tends to throw the can over onto its side into receptacles S, carried by the conveyers I. These receptacles,

I'IO

it will be seen, have somewhat flaring.

months, so that they easily receive a can and tend to straighten'it out into a position exactly transverse to the conveyer.

In order to insure a can falling over onto its side, a

stop T is provided at each side of'the conveyer O, which catches the bottom of the can,

and thus holds it baokwhile the arm is throwing over the top of the can. As the cans may not be exactly centered on the conveyers I, we provide guides r with flaring mouths, one for each conveyer. These catch the cans and center them exactly on the belt, so- 'that each.

dro ped into the hoppers E- he dischar ecylinder M may be arranged above the en less conveyer .O, eitherin. or

can is in exactly the proper position to be to open and close the peripheral opening of said pocket; and means for opening each of said valves to receive a can and for closing it immediately after the discharge of a can, substantially as described.

struck with the pivot of the valve as a cen- 'ter; and means for opening each of said valves to receive a can and for closing it immediately after the discharge of a can, substantially as described.
