Application filed September 16,1912. Serial No. 720,526.

To all whomit may concern Be it known that I, JOHIN S. Goats, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and;

ence marked thereon, which form" a: part of this specification.

My invention relates toa self-loading and unloading barrel truck, my object being" to provide a truck so constructed that barrels or kegs may be readily loaded thereon and asreadily unloaded therefrom, whereby the truck is'adapted for use in cities or other localities where barrels or kegs of goods are delivered at various places from the same" wagon.

' beer at various localities in cities.

My improved truck is constructed with a number of intercor'nin'unicating decks arranged one above another. In unloading the truck, the kegs or barrels are first elevated to the uppermost deck and delivered thereto. This deck is so constructed that it is slightly inclined downwardly from the rear toward the front, and as the kegs or barrels are delivered at the rear of the deck they will roll to the forward end of the same and pass thence to the decknex't below, upon which they travel in the opposite direction, and upon reaching the rear extremity of this deck they pass to the third deck, and so on until the last deck is reached and the keg or barrel has taken the lowermost position thereon. In this way the kegs or barrels are successively delivered until all of the decks are filled. Provision is made whereby the first barrel or keg of the lowermost deck is locked against escapingfrom the deck, hence as the other'kegs or barrels are successively delivered to the truck they gradually fill all the decks. When it is desired to unload, the movement of the elevator is reversed and the cage is utilized for lowering the kegs or barrels as they are successively released from. the lowermost deck:

If desired, trucks or barrels may be unlottdd from deck between the lowermost and t ppermost decks, 21's, for instance, when the load is composed of different sized packas barrels, half-barrels and he s, and the particular size to be delivered is coated on" a deck above the uppermost it will then be convenient to take the barrel directly tro'in an appended; rather than unload all of the barrels below order to alldw the desired barrel to reach the uppermost posit'roaof the lowermost deck.

Having briefly outlined my improved cons'tI-uctidn', I will proceed to describe the same in detail, reference being" made to the aecdm'pa'nying drawing, in which is illustrated an embodiment thereof.

In this drawing: F igure 1 is a side elevation of my improved truck, kegs or barrels indifferent locations being indicated thereon in dotted lines. Fig. 2 is a transverse section taken on theline 22 Fig. 3,

shown on a larger scale. Fig. 3 is a section taken the line 33,' Fig. 2, looking toward the F ig. 4 is a detail view of a device for automatically actuating the elevator cage to throw it to position for automatically delivering a keg or barrel to the uppermost deck. The device is shown on a larger scale in this View than in the general views.- Fig. 5' is a top plan View of the same, or a View looking in the direction of arrow 5, Fig. 4. Fig. 6 is a horizontal section taken on the line 6-6, Fig. 1, looking downwardly, the parts being shown on a larger scale. Fig. 7 is a vertical section taken through the elevator and cutting a edge thereof, the parts being shown on a larger scale. Fig. 8 is a fragmentary view of the operating mechanism of the structure, the same being shown in top plan view.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the running gear of a truck upon which is mounted a body 6 composed of a number of intercommu'ni'cati'ng decks 7, 8, 9 and 10. As illustrated in" the drawing, (see Fig. 2,) each of these decks is of a width equal to twice the length of the barrels or kegs to be carried by the truck whereby it becomes practicable 40 they are sufliciently strong to prevent the -to allow a barrel 16 to of two of the kegs or barrels placed end to end, the width being so regulated as to bring about this result without crowding.

Each compartment of each deck consists of angle iron tracks 12, the space between the inner and outer track members consisting of supporting bars 13 connected by transversely arranged bottom members 14. The tracks 12 are so spaced as to conveniently handle the various sizes of barrel packages. At the forward extremity of the uppermost deck the barrel-supporting members terminate at a suflicient distance in the rear to leave a space 15 of sufficient length pass downwardly to the deck 9 below. In order to prevent the barrel from falling suddenly from an upper deck to a lower deck, the upright frame-work 17 of the structure is provided with a spring-supported platform 18, the said platform being hinged at one extremity as shown at 19 and supported intermediate its extremities by rods 20 whose upper extremities are bifurcated as shown at 21 to straddle bars 22 with 'which they are pivotally connected. The

lower portions of these rods pass through bars 23 as shown at 24, the rods being slidalble therein. The upper portions of the rods are provided with stops 25 which are made fast on the rods and bear against the upper extremities of spiral. springs 26 which surround the rods, the lower extremities of the springs engaging stops 27 which engage the bar 23 and through which the rods also slide freely.- The parts 27 simply form hearings or seats for the lower extremities 'of the spiralsprings. The tension of these springs is so regulated as to yield to the Weight of the barrel while at the same time barrel from falling suddenly from one platform to the other, which might result in injury to the barrel or to the truck structure, or -both, as will be readily understood. As soon as the platform is moved downwardly to the proper position, the barrel rolls toward the opposite end of the lower deck to which it has now been transferred, and the platform under the influence of its springs returns. to its normal position. Substantially the same platform structure is employed at one end of each deck, these springsupported platforms being arranged at the opposite ends of adjacent decks, as will be readily understood from an inspection of the drawing. Hence, there is a platform 18 at the left-hand extremity of the uppermost deck 10, at the right-hand extremity of the next lower deck 9, and at the left-hand extremity of the deck 8, referring to Fig. 1 of the drawing, the said platform being always located at the opposite end of the deck from that where the barrel enters.

The right-hand extremity of the lowermost deck, or the location where the barrels are removed from the truck, is provided with a sort of escapement lever 28 consisting of a straight portion 29 having parts 30 and 31 extending downwardly from its 0 osite extremities. Normally, or While oading the truck, this escapement lever is inclined so-that its rear projection 31 is lowermost and arranged to prevent the barrel 16 from rolling from th truck while its opposite projection 30 is raised to allow the next barrel to engage the first. When, however, it is desired to unload barrels from the rear extremity of the lowermost deck, the escapement lever 28 is manipulated by means of an arm 32 which is secured to the escapement lever at one extremity and engages a sort of quadrant 33 at its opposite extremity whereby the escapement may be locked in any desired positionupon the quadrant. The escapementlever. is fulcrumed on the frame as shown at 34 As" this lever is tilted to raisefits projection 31' 1 and lower its projection 30, the rearmost' barrel of the lowermost deck will be released, while the next barrel forward will be engaged in the rear by the projection 30 of the lever and held against further movement until the removed barrel is taken care of in a manner hereinafter explained. The escapement lever will then be returned to its original position, and the next barrel takes.

the place of the barrel first removed, and in this way the barrels maybe successively removed with great facility.

Should it be desired toiremove a barrel from an upper deck, as from the deck 9, an auxiliary slat-ted platform 35 pivotally mounted on the frame-work as shown at 36 and normally occupyin an upright posi tion, is thrown forwarilly, whereby it is caused to rest upon the rear extremity of thedeck 9 which supports it in such position that the barrel 16 when it reaches the rear extremity of the deck 9 will pass to this platform and thence into position upon the elevator cage as hereinafter explained, whereby it may be lowered without removing the barrels from the lowermost deck. In this event a second escapement lever 37 fiilcrumed on the frame as shown at 38 and provided with downward projections 39 and 40,211: its opposite extremities is employed. A .crank 41 is connected with this lever while a rod 42 leads downwardly from the crank arm to a lever arm 43 pivotally connected-with the fulcrum 3 L of the escapement lever 28. By operating the lever 43 the escapement lever may be controlled in the same manner as the escapement lever 28 heretofore explained.

The manner of elevating the barrels, while loading the truck, as well as employing the same elevator construction for lowering the barrels 1n unloading the truck, Wlll now be described. A vertically arranged elevator frame 44 is mounted on the rear extremity of the body of the truck and extends the entire height of all the decks of the truck. This frame is composed of two U- shaped rear members 45 and two similarly shaped forward members 46. The lower extremities of the four members 45 and 46 are secured to the parallel arms 47 of a U- shaped frame 48 .which is loosely mounted and freely slidable on a transverse shaft 49. The upper extremities of the bars 45 and 46 are secured to a top frame 50 composed of side bars 51 and a transverse member 52 located forward of the U-shaped bars 46 and carrying rollers 53 which engage a transverse track 54 mounted on the stationary framework of the truck. The frame 50 is further provided with forward extensions 55 which carry rollers 56 which engage a track 57 from below, said tracks being transversely arranged and adapted to aid in the support of the elevator; carriage during its transverse movement on the truck from a position directly in the rear of the deck compartments on one side of the truck to a position directly in the rear of the corresponding compartments of the decks on the other side of the truck. During this transverse travel of the elevator carriage on the truck, the U-shaped frame 38 slides freely on the shaft 49.

Mounted on a shaft 58 journaled in the side supports 47 of the frame 48 are sprocket wheels 59 while corresponding sprocket wheels 60 are mounted on stub shafts 61 journaled in side members 51 of the frame 50. Upon these two sets of sprocket wheels are mounted endless chains 62 which run in ways formed by the U-shaped frame bars 45 and 46. Elevator cages 63 are connected with these chains in a manner best illustrated in Fig. 7 of the drawing. Each cage is composed of a bottom 64 and oppositely arranged top bars 65, the top bars and the opposite ends of the bottom of the cage being pivotally connected by means of front, rear and middle rods 66, 67 and 68 respectively. Each cage is suspended from the elevator chains 62 by means of links 69 whose upper extremities are pivotally connected with pins 70, the latter being suitably connected with the said chains. The lower portions of these links are slotted as shown at 71 and the bars of the cage are centrally and pivotally connected therewith by means of rivet pins 72 which pass through perforations formed in the upper extremities of the rod 68, and the slots 71 of the links 69. Depending guide blocks 73 are formed integral with the bars 65 of the cage, the said blocks being centrally located and occupying positions between the side members of the U-shaped bars -15 and -16 during the travel of the chains therewith. By virtue of these guide blocks, the elevator cages are maintained in the upright position while traveling upwardly with the forward runs of the endless chains of the elevator, since the U-shaped bars 46 have their side members arranged in such proximity as to produce this result. The rear flanges of the U- shaped bars 46 are cut away. .at the upper extremities of the bars, as shown, at 74, to allow the guide blocks to change their position, whereby the bottom 64 of the bucket is inclined to allow a barrel 16 to roll automatically from the elevator to the uppermost deck, after which the cages are carried with the chains as they pass over the uppermost sprockets 60, the cages passing thence downwardly in the collapsed position, since the U-shaped frame bars 45 have their front and rear flanges sufficiently spaced to allow the cages to assume the collapsed position by virtue of the ivot'cd connection of their several parts. -s soon, however, as the cages reach the lowermost extremity ofthe elevator, the said cages assume an upright position ready to receive a keg. Whenin this position the bottom of each cage rests upon a sled-like structure 75 composed of two runners 76 pivotally connected with the frame, as shown at 77. These runners are connected by transverse rods 78 and 79. The runners rest upon the surface where the barrels to be loaded are located, so that these barrels may be rolled first upwardly on the outer extremities 80 of the runners and thence to a position upon the bottom of the cage as indicated by dotted lines in Fig 3.

he elevator is operated from a suitable motor (not shown,) carried by the truck, the power bein taken from a main shaft 81 having a clutc connection 82 with a short shaft 88 carrying a beveled gear84 which meshes with either of two gears 85 or 86 carried by a sleeve 87 splined on a shaft 88. The gears 85 and 86 are arranged on opposite sides of the gear 84 whereby, when one gear of the sleeve 87 is in mesh with the gear 84 the shaft 88 rotates in one direction, while when the other gear on the sleeve is in mesh with the ear 84 the shaft rotates in the reverse direction. The sleeve 87, which is longitudinally slidable on the shaft 88, is shifted in one direction or the other by means of a suitable lever 89 having pins 90 which enter a circumferential groove 91 formed in a collar 92 fast on the sleeve. The lever 89 is pivotally connected at its lower extremity as'shown at 93 with the forward extremity of a rod 94, the rear extremity of this rod being exposed as shown at 95 for manipulating purposes. The rear extremity of the shaft 88 is provided with a pinion- 96 which meshes with a gear 97 fast on the shaft '19 upon which the elevator carriage is slidably mounted, as heretofore ex plained. This shaft 49 carries two gears 98 and 99 which are splrined on the shaft and arranged on opposite sides of the U- shaped frame member 48. These gears-98 and 99 are connected in operative relation with gears 100 and 101 mounted on opposite extremities of the shaft 58, by means of. short shafts 102 and 103 and gears carried by the said shafts. The shaft 102 has a gear 104 meshing with the gear 98 and a gear 105 meshing with the gear 100, while the shaft 103 has a gear 106 meshing with the gear 99, and a gear 107 meshing with the gear 101. The gears 98,99,100,101,104, 105, 106 and 107, as well as the shafts 102,103 and 58, constitute a part of the elevator carriage and move transversely therewith, the gears 98 and 99 being splined on the shaft 19.

The opposite sides of the frame at the to above the elevator carriage are provided with pawls 108, which are pivotally mounted, as shown at 109. When the carriage is moved to its limit of movement in either direction, one of these pawls will engage a top frame bar 51 in interlocking relation. Each pawl is provided with a pullcord, or chain, 111, which hangs down within reach of the operator, and the carriage may be released by pulling downwardly on the cord connected with the pawl which is in engagement with the. carriage. The pawls, however, are ar ranged to automatically interlock with the carriage when the latter is moved transversely in either direction to its limit of travel. 4

The elevator cages are successively tilted during the operation of the elevator to allow the barrels to roll from any cage to the uppermost deck,-see Fig. 3,-by means of a trip 110 mounted on the framework and having an arm 112 arranged in the path of one of the bars 65 of the cage, the said arm being arranged to engage the bar forward of its bearing in the slot 71' of the link 69. As the rear flanges of the guide bars 46 are cut away, as shown at 7 1, as heretofore explained, the cage is allowed to tilt in response to its engagement with this trip as the carriage continues its upward movement after the barrel has been delivered to the uppermost deck, and it will move past the trip by virtue of the fact that it is free to collapse, since the depending guide blocks 73 are no lon er traveling between the flanges of the gui e bars 46.

The use of the trip 110 heretofore described is that which occurs during the upward movement of the elevator cages while loading the truck. During the unloading operation, or when the elevator is traveling in the reverse direction, the elevator bar will engage the projecting arm 112 of this trip, but the latter will move by virtue of the fact that a part 113 of the trip is journaled in a bearing 11 1 secured to the under side of a frame plate 115 which is mounted on one of the frame bars 46 of the elevator structure. The part112 of the trip is normally held in a horizontal position, and, consequently, in a position to engage a bar 65 of any cage, by means of a spiral spring 116 which surrounds an eye-bolt 117 above the plate 115. a A nut 118 and a washer 119 being employed to form a stopl for the upper extremity. of the. spring w ile its lower. extremity bears against the upper surface of the plate 115. The eye-bolt passes through an opening formed in the plate 115, and its head 120 is pivotally connected, as shown at 121, with a short crank-arm 122 of the trip. The part 112 of the trip also constitutes a sort ofcrank-arm, whereby, as the cage engages the part 112 the trip will be turned in its bearing and the bolt will be drawn downwardly a short distance, placing the spring 116 under tension. The recoil of this spring will return the trip to its normal position as soon as the bucket has released the part 112. Furthermore, as the cages approach their downward limit of travel during the unloading operation, a hook-shaped trip 123 is detachably connected with an arm 47 of the elevator frame.

; The lower extremity 1241 of this trip is arranged to engage a bar 65 of the cage on its under surface, and forward ofits pivot, and thus serves to tilt the cage whereb the barrels may be automatically removed t erefrom if desired. This detachable trip 123 is not employed during the loading of the truck. A

The motor, (not shown,) which operates the shaft 81, may be run if desired without operating the elevator. In this event a bellcrank lever 125,-see Fig. 8, is employed to disconnect the member 126 of the clutch from the member 127, whereby the power is cut off from the elevator. This bell-crank lever is fulcrumed on the frame at 128, and one of its arms is connected, as shown at 129, with the forward extremity of a rod 130, the rear extremity of the rod being pivotally connected, as shown at 131, with a crank arm 132 fast on a rock-shaft 133, the rock-shaft having rearwardly extending arms 134C for convenience of manipulation.

From the foregoing description, the use and operation of my improved construction will be readily understood.

In loading the truck the barrels are carried successively by means of the cages 63 to a sufficient height to cause one of the bars 65 of any cage to engage the trip 110, the

trip in this event acting on the upper edge of the bar forward of its pivot, whereby the barrels are caused to roll on the uppermost deck, whence they pass successively to the decks below. In this manner all of the decks may be loaded with barrels, as they. will gradually fill, in a manner that will be readily understood. As a barrel passes from one deck to the next deck below, it en gages one of the hinged spring-supported platforms 18 which gradually carries it to the deck below, thus preventin any injury to the construction of the barre s.

Assumin that the decks have a horizontal width equal to the length of two barrels, the deck compartments on one side that are arranged one above another, are first filled, after Which the elevator carriage is moved transversely to a position immediately in the "rear of the other set of deck compartments, and the latter are filled in the manner heretofore explained. It is evident that the truck may have a width equal to that of the length of a single barrel, or two barrels, or even of a greater number of barrels, as may be desired. During the unloading operation, if the barrels are taken successively from the rear extremity of the lowermost deck, the escapement lever 28, which, as illustrated in Fi s. 1 and 3, is in position to form a stop for tile barrels, is shifted to release the barrel farthest in the rear, and in so doing its projection 30 is caused to engage the barrel immediately forward of the rearmost barrel, whereby the forward barrel is held against-movement until the rearmost barrel is removed, after which the escape ment lever is returned to its normal position and the next barrel moves to the rearmost position upon the deck and is removed in the same manner as just explained.

Assuming now that it is desirable to remove one or more barrels from an upper deck, say the deck 9, the platform 35, which normally occupies an upright position, as shown in Figs. 1 and 3, is thrown forwardly to a horizontal position whereby its free extremity rests upon the rear extremity of the deck. This opens the way for a barrel to leave the deck 9 and pass to a cage of the elevator whereby it is lowered, being removed in the same manner as if it had been taken from the lowermost deck. It will be understood that during the unloading opera tion the travel of the elevator is reversed so that the cages are moved downwardly instead of upwardly on the forward run of the endless conveyer.- In this event the trip 123 may be employed to tilt the cage to a position to allow the barrel to 'rol rearwardly from the cage as the latter descends to the proper level. In removing barrels from an upper deck, as the deck 9, the escapement lever 37 is employed in the same manner as the corresponding lever 28, the use of which has already been explained.

When the truck is traveling from place to place, or when the loading or unloading operation is not going on, the sled-like structure 75 is raised to the position shown in Fig. 1, its rearmost rod 78 being connected with a hook 135 which is pivotally connected with the elevator frame as shown at 136.

Attention is called to .the fact that the central upright bar 68 of each cage of the elevator is provided near its lower extremity with a guide-block 137 which passes between the flanges of the upright frame parts 46 and gives the cage stability during its vertical travel. The rear flanges of the frame bars 46 are cut away below their upper extremities, as shown at 138, to allow these blocks to' escape from the frame bars as the cage begins its travel with the chains over the upper sprocket wheels. It will be understood that before the blocks 137 could reach the upper extremities of the flanges of these frame bars, the cage, in traveling with the chains over the upper sprocket wheels, will have moved rearwardly a sufficient distance to make it necessary that the blocks 137 should escape from the spaces bet-ween the flanges of these bars, and the openings 138 are for this purpose. It should be stated, further, that the short or stub shafts 61, upon which the sprocket wheels 60 are mounted, are made necessary by reason of the fact that if a single shaft were em loyed extending from one wheel to the ot or it would prevent the travel of the cages with the portions of the chainswhich are passed over the uppermost sprockets.

In order that the elevator chains may be stopped when any cage is in any desired position in itsupward or downward travel, it is not only necessary to disconnect the elevator-operating mechanism from the power shaft, but suitable brake mechanism will be required in order to prevent the travel of the chains by virtue of the weight of a loaded cage. For this purpose I have applied a drum 139 to the shaft 88, the said drum being employed in connection with a hand brake 140, one extremity of which is connected with the truck as shown at 141,

while its opposite extremity is connected, as shown at 142, with a lever 143-fulcrumed at 1 1 1 on a bracket 146. By pressing downwardlyon the arm 147 of this lever, the brake band may be caused to engage the drum with the necessary friction for holding the elevator in the desired position.

The auxiliary platform 35 may be held in its upright'position,see Fig. 3,when not in use, in any suitable manner. As illus trated in the drawing, I pass a pin 148 through an opening formed in a part of the platform and cause the pin to engage a registering opening in the stationary frame work of the truck. When it is desired to use this platform for the purpose herein explained, the pin 148 may be removed.

By reason of the fact that the U-shaped frame bars 45 have their parallel flanges much farther apart than the corresponding flanges of the bars 46, the cages are caused to assume the collapsed position during their downward travel with the rear runs of the endless chains. By reason of this fact the descending cages do not interfere with the ascending cages, and the two sets of frame bars 45 and attimaybe brought nearer together.

Having thus described. my immtioo,

what I claim is:
