To all w/mm t may concern Be it known that I, FRANS KANKKONEN, a citizen of the United States, residing at Astoria, in the county of Clatsop and State of Oregon, have invented certain new and useful Improvements in Exhaust-Boxes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in cooking or heating apparatus for cans and other containers and more particularly to an apparatus for use in canning factories, this particular appa ratus being well known as an exhaust box and the primary object of the invention is to improve upon the general structure of devices of this character.

A further object of the invention resides in providing an apparatus wherein an improved conveyer mechanism is providedl with improved means for placing containers or cans thereon and removing the same therefrom at predetermined points on the device.

- 'A still further object resides in providing a device which is simple and durable in construction, substantially inexpensive to manufacture and one which will be very etlicient and useful in operation.

lVith these and other objects in view my invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specilication and claims:

In the accompanying drawings forming la part of this application: Figure 1 is a front elevation of the device with parts shown in section. Fig. 2 is one side elevation-thereof. Fig. 3 fis the opposite side elevation ofl the same. Fig. 4 is an enlarged fragmentary elevation of the device with parts in section and parts removed.l Fig. 5 is an enlarged vertical transverse sect-ion through the lower portion of the apparatus showing one set of containers or cans in position to be forced on the conveyer and another set in position to be removed therefrom. Fig. G is a horizontal section through the device. Fig. 7 is a plan view thereof. Fig. 8 is a detail vertical section through the device showing one set of containers in their posii tion as they have just been placed on the conveyer and another set of such containers havingr just been removed therefrom. Fig. 9 is an enlarged vertical section showing the position and operation of the spacer members with respect to the containers or cans, and Fig. 10 is a detail elevation partly in section of the retaining means used in connection with the timer or timing mechanism.

In describing the invention I shall refer to the drawings 'in which similar reference characters designatn corresponding parts throughout the several views and in which- 1 designates a housing or casing formed of any desired material and mounted on a base or supporting frame This casing or housing 1 is entirely inclosed and access may 'be had thereto or rather to the contents thereof through the medium of hinged

doors

2 and 4 mounted on the front thereof. Rotatably mounted in the side walls of this housing adjacent the upper and lower ends thereof are the shafts 5 and 6, respectively, and carried on said shafts adjacent the ends thereof are the sprockets 7 over which are trained the endless chains 8. Connecting the links of the pair of chains 8 at predetermined points in the length thereof are the transverse bars 9 to which are hooked or otherwise pivotally connected adjacent the outer ends thereof, the side plates or brackets 10 carrying the shelf-like supports 11. The one end of each of said shelf like supports 11 has an upstanding flange 12 thereon forming a stop for the contents of said shelf members and these shelf members together with their supports and the endless chains form an endless conveyer operatively mounted within this housing 1. The upper shaft 5 and correspondingly the complete carrier is caused to rotate at intervals through the medium of an approved mechanism herein described. Mounted for rotation in bearings 13 on the top of said housing 1 is a shaft 14, one end of which has a bevel gear 15 mounted thereon. Also mounted on the top of said housing or casing 1 is a bearing casting 1G the axis of which extends in a plane at right angles to the axis of the shaft 1l and rotatably mounted in this bearing 1G is a Shaft 17, the outer end of which has a drive pulley 18 mounted thereon. The inner end of said shaft 17 has a bevel pinion 19 mounted thereon which meshes with the teeth of the bevel gear 15 carried on the one' end of said shaft 14. Thus upon the rotation of said pulley 18 said shaft 14 is caused to rotate and said pulley derives its power from a belt 20 trained thereover and extending from a source of power (not shown).

Mounted on the opposite end of the shaft 14 just beyond the side Wall of the housing 1 is what is known as a Geneva gear 21 which is designed to intermesh with an additional Geneva gear 22, the latter being carried upon the adjacent end of the shaft 5. The gear 22 is similar to one of a pair of such gears as are usually used for the provivsion of an intermittent rotation of a shaft, the same being of star-like design having substantially radial channels or slots 23 therein terminating at their outer ends in the points of the star. The edge of said member 22 between the portions containing the slots or channels 23 therein is designed to form a plurality of concaved portions indicated at 24. The member 21, on the other hand is of disk-like formation the periphery of which is adapted to be received snugly in the concaved portion of said member 22. This member 21 has a portion cut therefrom as indicated at 25, this cut-a-vvay portion beinglconc'aved so as to clearly avoid engagement with portions of the gear 22 at certain points in the rotation of these memn bers. The shaft 14 also has an arm 26'carried thereon which projects considerably beyond the peripheral edge of the gear 21, the outer end thereof having a laterally extending stud 27 thereon which is designed for reception at predetermined times in the slots or channels 23 of said gear 22. It is obvious from this construction that upon the rotation of said shaft 14, the shaft 5 and all parts connected thereby will be rotated at intervals and in this manner the shelf-like supports 11 of lsaid endless conveyer or carrier are brought one at a time to a position whereby cans or containers may be supplied thereto and removed therefrom, as desired.

An improved feeding means is provided for this device and to this en d the side walls of the housing or casing 1 are provided with openings `28 which are arranged in vertical plane just forward of the vertical plane of the front` reach of the vertically operating conveyer or carrier. Mounted on the one side Wall of the housing 1 and projecting therefrom is a pair of brackets or arms 29 the outer ends of which terminate in bearings for the reception of the ends of a rotatable stub shaft 30. This stub shaft 30 carries a sprocket 31 thereon; and rotatablymounted in bearings 32 on the opposite side wall of the housin or casing 1 is an additional shaft 33. ounted on this shaft 33 and arranged in horizontal alinement with the sprocket 31 is an additional sprocket 311 and trained over the alining sprockets 31 and 34 is an endless chain 35 forming the basis of a horizontally operating carrier or conveyer. Formed on certain of the links of this chain 35 are the outstanding ears or arms 36 to which are secured the plate-like members 37. The edges of these plate-like members 37 are adapted for abutment one with the other so that when the chain 35 is in operation, a conveyer is provided having a perfectly flat surface and each of said plate-like members is adapted to receive a can or container in a.

manner to be hereinafter more particularly set forth. 'The end of the device from which the brackets or arms 29 extend forms the entrance end of the device and guide bars 78 are provided in connection with the housing or casing 1 at said end whereby to provide a guiding means for the entrance of containers or cans to the conveyer or carrier feeding the cans or containers to the device.

ln order `to permit the upper reach or stretch of the horizontal conveyer or carrier to remain in a substantially horizontal plane and prevent the sagging thereof under weight ofthe contents of the same, a pair of

longitudinal bars

39 and 40 are provided, the` same being spaced one from the other and adapted to receive the outer edges of the plates on the upper reach of said conveyer. These

bars

39 and 40 are mounted in the frame 2 at the lower portion of the housing or casing 1-and are spaced yone from the other, the bar L10 being disposed nearer the front face of the device. The bar 39 receives on the top face thereof flatly the lower faces of the plate-like members 37 while the upper face of said bar "40 is offset as shown at 40 to receive the outer edges of said plate-like members 37 thereon. Thus, said upper reach of the conveyer or carrier operating horizontally on the device is supported and prevented from sagging below a predetermined horizontal plane. This predetermined horizontal plane is the one at which the shelf-like supports 11 of the vertically operating conveyer are adapted to stop through the operation of the Geneva gears above described. In this manner the cans or containers carried on the feeding or horizontally operating carrier may be readily removed therefrom when placed kon the shelf-like support of the vertically operating carrierythis means for removing said containers or cans being an essential feature of the invention as will be hereinafter more particularly set forth.

As stated above, this device is particularly adapted to be used in connection with canning factories and in the use of the device, cans are applied tothe feeding carrier to be carried to this device for steaming purposes. However, the tops of the cans`or containers are not sealed at the time the same are passed to this device and thus an annular projection will be formed on the upper portion of each can which must be compensated for in the positioning of said can on the feeding carrier. A spacing means is thus provided on my device to space each can one from the other in the setting of the same on the carrier so that each will be in perfectly upright position thereon and ready for distribution to the vertically operating conveyer at the time the operating means is engaged therewith, as will be hereinafter set forth. In carrying out this idea, an angle bar. 41 is removably secured by means of the screws 43 to the front face of the longitudinal bar 40 above referred to. The same is so positioned thereon as to dispose the angle downwardly and permit the outer face of the upper angle portion of said bar to be disposed in a plane slightly above the plane of the upper face of said bar 40. This upper angle of the bar 42 is provided with slots 44 at predetermined points therein through which is extended the threaded Shanks of bolts 45 the latter being engaged with a horizontally arranged plate 46. This plate 46 forms a support for my improved spacing members and through the medium of the slots and bolts as above mentioned, this plate is adjustable on its supporting member.

My improved spacer members are 1n the form of turnstiles indicated as 47, there being a plurality of the same rotatably mount` ed on the upper face of said. bar 46 adjacent the inner edge thereof. These turnstile spacer members comprise sleeves 48 rotatably mounted on studs 49 in spaced relation to one another, each sleeve being provided with four radial arms 50, and one pair of oppositely projecting arms being in a plane above the plane of the other opposiiely projecting arms, such being the arrangement on each turnstile or spacer. These members are so arranged with respect to. one another as to permit the radial arms of one member to escape contact with the radial arms of the adjacent members in the operation of said device. In this manner as the cans or containers are fed to this device throu h the medium of this feeding or horizontaxC-lly operating carrier or conveyer, each can will Contact With an arm of these spacers and cause said spacers to be rotated on their bearings but said arms of the spacers will retain said cans in spaced relation to one another and thus accomplish the result desired.

Arranged at a point adjacent the end at which the shaft 33 is disposed is a bar 5l which forms a stop bar against which the first of each set of containers carried into the device is adapted to contact as the same are carried into the device through the medium of this feeding conveyer. When this first can Which is carried into the device is stopped by contact with said stop barV 51, it will be seen that the complete set or series of cans or containers carried vinto the device will be stopped but the conveyer or carrier will continue in its operation, as the retention of these members on the upper reach of the carrier or conveyer will not hinder the operation of the latter. At this time, other cans which are being fed to the device will be prevented from entering through the entrance opening, this -means being hereinafter and more particularly set forth. The sides of thc housing or casing l are also provided With an additional pair of openings through which extend the reaches of a discharge carrier. This carrier which is indicated as 53 consists of a chain 54 and plate members 55 secured thereto the same being identical to the chain.- and plate-like mem-l bers described in connection with the .first mentioned horizontal and feeding carrier. This chain 54 extends over a sprocket 56 also carried on the shaft 33 and extends also over a sprocket 57 mounted on an additional shaft 58 at the opposite end of the housing or casing. From this constructiony it will -be seen that this conveyer or carrier 53 operates in the same direction as the first-mentioned or feeding carrier, but the outlet thereof is at the end at which the shaft 33 is mounted. This carrier 53 is adapted to leadto a chute or other means whereby the contents thereof may be directed to any desired member (not shown). This carrier is so arranged that the upper reach thereof is substantially inV the same horizontal plane with the upper reach of the rst mentioned horizontal carrier and the vertically operating carrier is also so constructed that Whenv a shelf-like support 11 is arranged in the same horizontal plane with the first mentioned or feeding carrier and adjacent thereto, an additional shelf like support on said vertically operating carrier will be also arranged in the same horizontal plane therewith but immediately adjacent the discharge carrier 53. In this manner it will be seen that at 4the same time the contents of the feeding carrier are discharged to the vertically operating carrier the contents of one shelf of the latter may be discharged onto the discharge carrier last mentioned. The particular means for discharging the contents of the feeding carrier to the vertically operating carrier and the means for removing the contents from the latter to the discharge carrier forms an essential feature of this invention and will be hereinafter more particularly set forth.

The inner face of the bevel gear 15 is provided with a cam slot 59 in Which is mounted a laterally extending stud 60 carried on the upper end of a vertically arranged rod (Si. This rod 6l extends along one side of the housing or casing l, depending to a lll@ point a short distance above the outlet openmg of the device. The extreme lower end of the rod is guided through a guide keeper 62 carried onthe side of the housing 1 and formed on said rod at a point adjacent the lower extremity is a laterally extending T- arm 63. xLoosely connected with the ends ofsaid arm 63 through the medium of a pin and slot connection are the crank arms 64 carried on the one end of a pair of rods 65, the'latt'er bein rotatably mounted 1n the side walls of the lIiousing 1. These rods 65 extending longitudinally of the casing or housing 1 on each side of the vertical reaches of the vertically .o erating carrier have each a -pair of depending arms 66 u adjustably mounted.. thereon, said arms being termed for convenience, feed arms. These arms 66 depend to planes adjacent and just above the horizontal planes of the upper reaches of -said feeding and discharging carriers and secured to the lower ends of said arms are the angle bars 67 which. for convenience may be termed feed bars, inasmuch as tne function thereof is to engage the cans or containers on the respective members and discharge the same to other members adjacent thereto in a manner to be hereinafter more particularly set forth.

In the normal position of the Idevice as shown in Fig. 5 of the drawings, the arms 66 are in .their outward position but upon an actuation of the rod 61 said arms 66 will be disposed inwardly to cause the cans or containers on the feeding or inlet carrier to be discharged onto the adjacent shelflike support of the vertically operating carrier at the same time the cans on a shelf or support vof the vertical carrier are adapted to be discharged therefrom onto the discharge carrier 53. The position of the parts after the discharge of the cans from the respective members may be clearly seen in Fig. 8 of the drawings. The horizontally operated carriers oi' conveyers are disposed immediately adjacent the vertical planes of the reaches of the vertically operating carrier so that but little space is provided between a shelfl or support 11 and the upper reaches of said carriers. the contents of one member may be readily discharged onto the other withlittle or no danger of upsetting the contents, such as the cans or containers. It is desirable, however, to provide a means for preventing any possible upsetting of the cans as'the same are discharged from one shelf of the vertically operated conveyer to the discharge carrier 53 and. to this end2 a longitudinal stop bar 68 is provided. This bar 68 receives' the cans in contact therewith as said cans or containers are discharged from a shelf or carrier of said vertically operated conveyer and thus there is no chance or opportunity U5* of said cans j or containers being `thrown In this mannerl from the discharge `carrier as the same are discharged from the one member to the other. It is also desirable to provide means for preventing the oscillation of the shelf like support on the vertically operated carrier as the cans are forcedy or discharged therefrom. To this end ins or arms 69 are provided on the side walls of the casing or housing 1,'the same projecting inwardly to contact with the vertical side lates l0 of said supporting members on e conveyer. This obviously performs the function desired.

As the feed conveyer on the device operates, the vcans or containers thereon contact, as stated above, one at a time with the spacers or turnsti'le members above described and it is probable that the contact of said cans with said s acer members will move said cans from t eir original positions on the conveyer. In order to prevent said cans or containers being moved to a point beyond the inner edge of said feed conveyer I have provided an improved means forming a stop or the like against which the said cans may contact. Mounted in the forward portion of the frame 2 in a plane just below the plane of the upper reach of' the feed conveyer are the small pintles 70. Mounted for oscillation thereon are the L-shaped levers or the like 71 one arm of each of which projects upwardly and is enlarged as shown at 72, the latter end being adapted for engagement with the lower bar 67 of the feed arms 66 at the front end of the device. The other arm of this lever 71 projects inwardly below the lower reach of the feed carrier and has an angle bar 7 3 engaged therewith, the one angle portion of said bar being adapted to project upwardly through the slight space between the feed carrier and the forward reach or stretch of the `vertically operating carrier or conveyer. In the normal position of the device, as shown in Fig. 5 of the drawings, this lever being engaged by the bar 67 of the arms, 66 will be so disposed as to position this bar 73 between the feed carrier and the forward stretch of said vertical conveyer or carrier, thus forming a stop for cans or containers onthe feedrcar# rier.' This bar 73 forms substantially an upstanding flange on the upper stretch or reach of the feed carrier and the disposition of the cans on said feed carrier out of their original positions will not be such as to dispose the same beyond the inner edge of said carrier or conveyer in view of this particular stop mechanism. However, these levers 71 are such that when the arms 66' are disposed inwardly to dispose the cans or containers from the respective members to the adjacent members the inner ends of said levers will drop downwardly of their own weight. This provides a clear space between the 'feed conveyer and the shelves. of the vertically operating conveyer so that the cans may be discharged from the former to the latter without obstruction. When the arms 66 are disposed to their in itial positions again, however, the same will contact with the enlarged end 72 and oscillating said levers on the shaft 70, will dispose the same to their initial positions as shown 1n Fig. 5. The ositions of these levers 71 when in their owered or inoperative pos1- tions may be clearly seen from Fig. 8 of the drawings.

As stated above, when a predetermined number of cans or containers on the carrier indicated as the feed carrier are received within the housing or casing 1, a stop mechanism is designed to automatically operate, thus preventing any further feeding of cans into the device. i out this idea, a longitudinal rod 74 is mounted for sliding movement through guide keepers 75 on the side walls of the device forming the entrance end thereof. The lower end of this rod 74 has pivotal connection with one arm of a bell crank lever 76, the latter being fulcrumed at the junction of its arms on a stub shaft 77. The opposite arm of said bell crank lever at the free end thereof has pivotal connection with a plate-like member 7 8 which forms one side of the guide means at the entrance end of the device and it will be seen that upon an actuation of said rod 74, said bell crank lever will be actuated also, whereby to dispose said plate member 78 inwardly and thus prevent cans or containers being fed through the guide means. The upper portion of this rod 74 is distorted as shown at 79 to avoid contact with the Geneva gears at the upper end of the device and the eX- treme upper end of said rod has pivotal connection with a lever 80 which is fulcrumed intermediate of its ends as indicated at 81. The opposite end of said fulcrumed lever 80 is distorted and bent arcuately as shown at 82 the same being designed for engagement with the laterally extending stud 27 on the arm 26. Thus as said arm 26 is caused to rotate with the operation of the device the same will contact with said arm 82 and thus actuate this stop mechanism to permit cans or containers n to be fed to the device at intervals.

, In practice, the complete machine is set in operation by the rotating of the main driven shaft 14 of the device and cans or containers are fed to the main housing or casing through the medium of the feeding carrier, the latter passing through the guides at the one end of said housing or casing. At a predetermined point in the rotation of the main driven shaft 14, the stud 27 on the arm 26 will contact with the arcuate end of the arm 82, thereby causing the stop mechanism to be actuated to pre- In carrying f vent the further feeding of the cans or containers to the main`housing or casing. This mechanism is so timed that the same will permit just the roper number, and no more, of cans to be ed within the housing and thus there will be no jamming or crushing of the cans or containers between the stationary and the operating parts of the device when the feeding arms are set in motion. This stop mechanism is caused to operate simultaneously with the actuation of the feed arms which are obviousl caused to operate upon the actuation of t e longitudinal bar or rod 61. This latter bar is drawn upwardly at a predetermined'point in the rotation of the main driven shaft through the medium of the connectionl of said bar with the cam slot in one face of the gear 15. Upon the actuation of the feed arm, the cans or containers on the feeding belt which are held in position within the housing or casing 1, will be discharged from the feeding belt or carrier to a shelf or the like on the elevator as said feeding arms contact with said cans and force the same inwardly. This endless carrier or elevator operates at intervals in view of the Geneva gear connection and is so constructed that one shelf is adapted to aline with the feeding carrier at each interval at whichI the same is stopped. As the operation is continued, the shelf which first receives the cans will finally reach a point on the opposite side of the endless carrier which is in the same plane with the upper reach of the discharge carrier and when so disposed, an actuation of the feed arms will discharge the cans from the last mentioned shelf or support to the discharge carrier of the device, simultaneously with the discharge of the cans or containers from the feeding belt to the shelf or support of the elevator at a point opposite. Each succeive operation of the device is the same and as the steam is passed through the main casing or housing of the device, it will beyseen that the cans and the contents thereof will be thoroughly steamed. It must be here also stated that the shaft which drives the speed and discharge conveyers is driven directly from the main driven shaft so that said feed and discharge conveyers are operated simultaneously with the operation of the main conveyer or elevator of the device. In carrying out this idea a short shaft 79 is rotatably mounted in the bearing 80 on the top of the casing 1 in longitudinal alinement with the shaft 17 which is mounted in the bearing 16. This shaft 79, however, is disposed on the opposite side ofthe shaft 14 from that on which the shaft 17 is disposed and carried on the inner end of 'said shaft is a bevel gear 81 which meshes with the teeth of the bevel gear 15. Carried on the outer end of this short shaft 79 is a pulley 82 over which is trained a driving belt 83 the latter being also trained over an additional pulley 84 carried on the outer end of the shaft 33. Thus it will be seen that as the shaft 14 is rotated, said shaft 33 will also be caused to rotate by the means hereabove described and shown in the drawings.

From the foregoing, it will be seen that I have provided a simple, durable and comparatively inexpensive means for carrying out the objects of my invention and while I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to, within the scope of the appended claims, without departing from the spirit or sacrificing any of the principles of the invention.
