UNLOADING APPARATUS.
Specification of Letters Patent.
Application filed January 18, 1903. serial'no. 411,463.
To all'whom itma/y concern:
Be it known that we, FREoEnIoK S. SNYDER and ALoNzo F. BURT, citizens of the United I car without handling, and which is so arranged that it may be readily raised or lowered, so that all the material in the boat. or vessel may be removed, and which apparatus may be raised out of the way of the boat or vessel when not in use.
A further object of the invention is to provide means which may be operated continuously, and which may be employed to raisecoal, ashes, sand, or other material and transfer it. from a boat, car or other container, and which is so constructed that the elevating means is properly protected and will not be interfered with while operating the apparatus.
lVith these and other objects in View, the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this specification, and will then be pointed out in the claims at the end of the description.
In the drawings, Figure 1 is a vertical section through a boat showing the apparatus in full lines in position to receive the material and to discharge the same into a car located convenient to the apparatus. Fig. 2 is a vertical longitudinal section of the apparatus. Fig. 3 is a side elevation of the apparatus showing its position while unloading a boat that has a high deck load. Fig. 4 is a detail plan, partly in section, of
. one of the buckets and platform. Fig. 5. is
a side elevation, partly in section, showing a Somewhat different form of apparatus. Fig. 6 is an enlarged side elevation, partly in section, of the unloading apparatus shown in Fig. 5. Fig. 7 is a transverse section of the lower portion of the apparatus. Fig. 8 is a detail perspective view of one of the buckets used in connection with the apparatus of Figs. 5 and 6. Figs. 9 and 10 show how the frame may be made of structural steel; and Fig. 11 shows how two chains may be used.
While the apparatus is shown-as applied to unloading a boat or vessel, and as if the frame was made of sheet metal, it will be understood that the apparatus may be employed for various purposes and in various connections, and that the frame work as well any of the other parts may be made of structural steel or other material suitably braced, so that the same may be light and strong, and that the frame may be of any suitable form to adapt 1t for-the various uses to which it may be put without departing from the character of the invention.
The vessel 10 may represent a canal boat having the usual hatchwayor opening 11 through which material may be elevated, and adapted to be lowered in the hatchway is an elevating apparatus 12.- This apparatus may be variously constructed. As
shown the frame 13, is of metal, and in practice we may make the said frame in a skeleton form by employing steel and suitably bracing the parts together in substantially the same way as is employed in building columns, girders and the like, though the construction of the frame may be varied as desired. The sides 14 of the frame are held apart and suitably braced by bolts 15, and said frame is pivoted to a bar or shaft 16 arranged upon any suitable support as a base 17. The frame may be fixed or it may be adjustable along a shaft to adapt it to be adjusted to various positions, or the entire support may be moved lengthwise of the vessel as will be presently described,
and to permit the apparatus to be placed in terial convenient to the hatchway may be entirely removed; and while only one unloading apparatus is shown two or more may be employed so that the unloading may take place from several hatchways of the vessel at the same time. The pivoting of the frame to the shaft 16 permits the apparatus to be raised or lowered as the material is unloaded, and also permits the apparatus to be raised entirely free of the boat or vessel, which is very desirable, and in fact necessary where the boat is provided with masts. To secure this result, we may provide on the frame 13 of the apparatus an eye bolt or other attaching means 18 at any suitable point, and connected to this bolt is a cable or other flexible connection 19, which passes over a pulley 20, Fig. 1, located upon the frame 21, and said cable passes around a second pulley 22, and from there toa drum 23, which may be operated by means of a motor 24 or otherwise. The said motor 24 may be so arranged that the shaft 16 will serve as the armature shaft, or as a continuation thereof. By this means the apparatus may be raised or lowered when the motor is operated, and if desired may be moved entirely clear of the boat or vessel 10.
The frame 13 has a sprocket wheel 25 secured to the shaft 16, and passing around the sprocket wheel is an endless chain 26, which may be of any suitable form, and said chain also passes around a sprocket wheel 27 secured to a transverse shaft 28 located near the outer portion or lower end of the apparatus, so that when the shaft 16 is rotated, the sprocket wheels will impart movement to the chain in the direction indicated by the arrows. The frame 13 may be of any desired form and length, and is preferably curved, and to the chain 26 issecured a plurality of buckets 29. These buckets may be variously constructed according to the use to which they may be put. For unloading pulpwood, they are preferably flat, and have one edge thereof slightly curved to engage the logs of pulpwood, and projecting from the inner edge thereof are lugs 30 in which is held a shaft 31. This shaft 31-is provided at its ends with rolls 32,
and said rolls have recesses therein, so that the shafts 31 will not roject entirely therethrough, and as said uckets aremoved by the chain 26 the rollers 32 will travel along the track 33 in their upward movement, and along the track 34 on its downward movement. The track 33 comprises an inner member 35 and an outer member 36 projecting inward from each side 14 of the frame of the apparatus, and the track 34 comprises a single member projecting inward from each frame. The buckets 29 are provided near their upper edge with rollers 37, which are held in brackets on said buckets, and projecting from said buckets are bars or brackets 38 on the lower ends of which are rollers 39, which are adapted to engage the lower rail or member of the track 33, so as to properly hold the buckets in their pro er position while carrying the logs of pu pwood upward to be discharged. The member 36 of the track 33 is somewhat extended to guide'the logs as they are discharged, and the sides 14 of the frame of the apparatus are somewhat enlarged, as at 40, so as to form a guide or chute for the pulpwood as the latter is discharged, particularly when the apparatus is used in the position shown in Fig. 3 for a high deck load, and as the pulpwood is discharged it passes to an inclined platform or chute 41, and from there to a car or other container 42, which has its track arranged convenient to the apparatus.
To cause the buckets to move within the frame during the downward movement. thereof, after discharging the material, we provide one or more trips 43. These trips 43 are in the form of bars which project inward from the buckets 29, and as the chain 26 passes around the sprocket 25 it will engage the pin, stop or projection 44, and will tilt the bucket and swing the same with the shaft 31 as a pivot, so as to force its outer end inward, and to cause the roll 37 near the outer surface thereof to ride upon the inner side or face of the track 34. The frame is provided with a supplemental track 45', which serves to guide the rollers '32 and said track has two members 46 and 47 one of which is longer than the other, and both tracks have their ends flared so that the friction rolls 32 will readily pass between the same in,their downward movement. The track 34 is somewhat shorter than the track 33, and as will be seen when the buckets are passing downward after thesam e have been forced inward by means of the bar 43 and pin or projection 44, the said buckets will travel along the inner surface of the track 34 with the rolls 39 and 37 supporting the same. By this means the buckets are moved within the frame on the downward movement so that they will not project'beyond the outer surface thereof, and will thereby be entirely free of any obstructions, and cannot strike or engage any part of the vessel in case the frame of the apparatus should rest against the same.
The buckets in their upward movement as they pass around the sprocket wheel 27 will engage the inner curved end of the member 36 of track 33, and will automatically open or assume their proper relative position, so as to project beyond the frame in position to receive the pulpwood logs. The buckets 29 are provided centrally thereof with an opening or slot 48, and in this opening is adapted to enter a tongue or projection 49 of a platform 50. This platform 50 may be of any suitable form and has inward projecting ends sition so as to extend upward, and when arranged between the lugs 54 and 55 will have a different inclination according to the position-of the apparatus. The arrangement of the platform not only makes the same detachable and readily applied to the apparatus, but the tongue 49 thereof assists in cansing the logs to be always engaged by the buckets.
It'is desirable in many instances to have the lower part of the apparatus frame adjustable to adapt it to move relatively to the other part of the apparatus. F or this purpose the frame of the apparatus comprises two members 57 and 58. These members are pivoted together at 55),and to the member 57 is held a worm or segmental gear 60, the teeth of which is engaged by a worm or screw 61, which is held in lugs 62 on the member 58, and has its stem or shaft provided with a handle 63 by means of which said member 57 may be moved relatively with respect to the member 58. \Vhen thus constructed each track 33 and 34 must'be divided, and at the joint between the members 57 and 58 of the apparatus each member of each track is provided with a spring or other plate 64, which is adapted to close the space between the joints in the tracks, so
- that the rolls of the buckets will readily pass along said tracks.
The support and frameQl may be made of wood or metal of any suitableconstruction, and said frame may have its platform 65 provided wit-h wheels 66 on the under surface thereof, which are'adapted to travel along the rails of a track 67 The rails of the track are held to the ties 6S, and to'the ties is held a third rail 69, along which is adapted to travel one or more wheels 70, each of which is supported by a bracket 71 carried by the platform 65. The wheels may be for the purpose of a guide and are so arranged that the weight of the apparatu will not. tip the supporting frame.
p The operation of the apparatus will be readily understood from the foregoing description when taken in connection with the accompanying drawings. In unloading a vessel of pulpwood or like material, it is only necessary for the logs to be placed upon the platform 50, and by reason of its incline they will naturally position themselves so as to rest against the rail or outer surface platform serving to prevent the log from falling into the open space or opening for the passage of the bucket. As the endless chain :26 is operated by imparting motion to the drive shaft 16 the successive buckets will engage the logs, and will carry them along the outer surface of the frame '13 as shown in Fig. 2, and when they reach the upper. end of the frame they will fall or be discharged on to a platform or chute 41, and from there into the car 42 or other receptacle providedto receive the logs as they are transferred from the boat. In this way it is unnecessary to handle the logs except to place them onv the platform, and the appabuckets and their mode of operation is substantially the same as already described, ex
cept that there are two bars 72 serving as trips instead of one, and the buckets are not shown as being provided with rolls near their outer edge. The frame 73 is shown as supported by a shaft 74 to which it is pivotet relatively movable members. This frame is enlarged at its lower end to form a boot T5, and the lower shaft 76, around which passes the endless chain, is adjustable by having said shaft 76 journaled in movable boxes 77, and these boxes are engaged by screws 78 to force them in one direction, While springs 79 force the boxes inthe opposite direction; This'permits the slack in the endless chain to be taken up, and the boot serves to protect the buckets from injury. The platform shown is substantially the same as in the other figures.
. \Vhile We have shown the frame of the apparatus as of a particular form and made curved so as to adapt it for the particular purpose of unloading boats, and have shown the frame as being solid at the sides and braced by transverse bolts, it is to be understood that the apparatus may be made to unload or transfer, coal, ashes, sand or other material, and that the form of the apparatus may be variedto suit various requirements, as well as to construct the buckets in such a way as to hold and positively carry the material according to the nature thereof, and that the frame may be made much lighter by constructing the same as shown in Figs; 9 and 10. In these figures the frame has the U-shaped bars 80 and L-shape-d bars 81, which are joined together by the plates or bars 82, and on the inside thereof if necessary, so as to provide a light, effective, and
strong frame for the apparatus. 43 of the frame 13, the tongue 49 of said In Fig. 11 the'frame maybe constructedin any suitable way, and instead of having a single endless chain 26, the buckets may and said frame is not divided into be operated by a chain having two members 83 and Sat, which are properly secured to the axles 85 of the buckets, and are adapted to move along the rails or tracks of the frame 14.
From the foregoing it will be seen that a simple, effective and continuously moving carrying means is provided in which the material as pulpwood may be quickly transferred from a boat or other container to a suitable discharge point, that the said device may be longitudinally or vertically adjusted to permit it. to be readily lowered into the boat or to be quickly raised so as to be entirely out of the way ofthe boat when not in use, and that the device is so constructed that the buckets will not beinterfered with by any obstruction, as the said buckets after discharging the material are made to move entirely within the frame, and therefore cannot be injured while the apparatus is being operated.
Having thus described our invention, we claim as new and desire to secure by Letters Patent 1.
