SPECIFICATION forming part of Letters Patent No. 502,142, dated July 25, 1893.
Application filed January 7, 1893- Serial No. 457,538- (N0 model.)
To all whom it may concern:
Be it known that I, PATRICK RYAN, of New York city, in the county and State of New York, have invented a new and useful Improvement in Dumping-Scows, of which the tollowing is a full, clear, and exact descrip- My invention relates to improvements in dumping scows or boats, used for the reception and transportation of material from one place to another point where the load is to be discharged, and has for its objects to provide a strong and capacious device of the character indicated, which will be convenient to load, and that may be quickly adjusted to discharge the load, partly or entirely, by an easy manipulation of mechanism that is a part of the improvement.
To these ends my invention consists in the construction and combination of parts, as is hereinafter described and claimed.
Reference is to be had to the accompanying drawings forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a side View of the device. Fig.
2 is a plan view broken away to expose parts below the deck at the ends, one platform on the main deck being also shown broken away. Fig. 3 is an end view; and Fig. 4 is a transverse sectional view, on the line 44: in Fig.
2, showing parts adjusted to'dump a load from the deck.
The hull A is by preference given the form of a scow, being made fiat on its bottom and having upright parallel sides.
The ends of the deck of the scow are located in the same horizontal plane fora suitable distance, to provide a sealed cover for the bow and stern portions, said decks B being provided of a sufficient height, which may be of greater elevation than the main deck, to afford room for the manipulation of mechanism located near each end of the hull and which will be presently described.
The bottom of the hull A is curved upwardly at each end, so as to join the deck portions B, as indicated in Fig. 1.
The main deck O O of the hull is partly level and partly inclined, the central level portion 0 being extended a proper width on each side of the median line of the hull, and supported near the edges by upright walls D,
mit the deck portions 0' to form angles of about forty-five degrees with the parts they are affixed to at their edges. At each end of the main deck 0, 0, vertical walls E are erected, and extend from the inner terminals of the decks B, so as to close the spaces intervening these decks and the main deck.
At the center of the hull A, alongitudinally-extending stringer F is imposed upon and secured to the level main deck portion 0, this beam being of a proper thickness to serve as a support. for adjacent edge portions of tilting tables G, which will be further described. At spaced intervals throughout the length of the hull, a series of similar stanchions H, is vertically erected, each'having a foot piece a seatedupon and secured to the bottom of the hull A. 'The stanchions H are of such a length as will adapt them to pass through the deck portion 0 and stringer F, and extend a proper height above the latter, and each is provided with a cross bar I) on its upper end, as shown in Figs. 3 and 4.
On each stanchion H below the deck portion B, similar knee-braces c are affixed, which braces bear upon the deck and serve to sustain it, transferring load strain to the stanchions.
Near the outer edges of the deck portion 0, at spaced intervals apart, a series of journal boxes d is secured, for the rotatable support of two similar rock shafts e, which shafts are designed to sustain the tilting tables G, and adapt them to rock from a level width of the platform to afford a support for another part that will be presently described.
At the longitudinal centers of the batten bars h, hub like enlargements are formed which are perforated in alignment, said holes being of equal diameter, and adapted to receive the shaft 2 that is thereto secured by any suitable means. The height of the journal boxes (Z and thickness of the stringer F, are so proportioned that each platform 9 will be located in a horizontal position when the inner ends of the batten bars 7t rest on the stringer, as represented in Fig. 3.
Upon the inner side edges of each of the platforms g a vertical wall g is erected, these walls being stiffened in their connection with the tables by the end walls 9 preferably shaped on their free edges, as shown in Figs. 3 and 4, and are firmly attached by their other edges to the ends of the tables and upright walls thereon. To further strengthen the platforms g, theyare each provided with a row of posts 2', erected at their transverse centers and of a suitable height, and secured thereto at their lower ends. The upper terminal of each postin a row is attached to the upper ends of the similar truss-rods 11' that extend diagonally downward in opposite directions from said post and are secured to the platform g, near its side edges, the truss-rods having each a turn buckle 2' introduced to permit said rods to be adjusted for length, so as to enable an upward draft strain to be applied to the opposite edges of each platform which will counteract the sagging effect of an imposed load.
There is a series of stay rods m furnished. for each table G, of such a length as will permit them to extend from the outer edge of each platform to the top edge of the vertical wall 9' thereon, said rods being each provided with aturn buckle m. When the stay rods m are not in service as braces, their hooked top ends loosely engage staples at the top of the walls g, so as to be removably retained in convenient position for another adjust ment, as will be explained. When the tilting tables G are located with their platforms g in the same horizontal plane, the turnbuckles m afford means to adjust the length of the rods on, so that their similar hooks may each be introduced through an eye-1101c formed in an appropriate end of a cross bar I), so as to removably lock the rods to the upper ends of the stanchions H, and thus throw a part of the load strain imposed on the platforms upon the stanchions, and also aid to prevent the tables G from tilting while such a connection of parts is maintained. A further means for supporting the outer edges of the platforms g, consists in providing each platform with a series of curved braces n bent to form arcs of circles of which the axis of each shaft c is a radial center. One end of each curved brace n is attached to the lower side of a platform g, near the outer edge, the series of braces for each table G passing through properly located perforations in the inclined deck walls 0, and thence inwardly through holes of a proper diameter in the vertical walls D, as shown in Fig. 4., a stufling box n being provided for each curved brace where it passes through the deck, so as to prevent water from entering the hull at these points.
hen the tables G are adjusted to receive a load upon the upper surfaces of the platforms g, the curved braces 42 will be drawn into the position indicated at the right of Fig. 3; and as shown in said figure, a space intervenes the inner ends of the braces and the adjacent sides of the vertical walls D, which space is filled by two lapped Wedges n for each brace and which, when fully inserted, afford a support to the brace ends they engage, adapting the latterto aid in supporting the outer edges of the platforms g.
A series of bracket blocks 0 is arranged along outer edges of the platforms g, having vertical faces that align with said edges, and on the latter a comparatively narrow side board g is hinged so as to be adapted to fold upwardly and have contact with the blocks 0, or lie in a plane co-incident with that of the top face of each platform, as shown in Fig. 4. At each end of the platforms g, a hook is loosely secured to the end walls g and made to interlock removably with a staple on the upwardly folded side board g thereby retaining the inner ends of the side boards in close contact with the bracket-blocks 0, said parts 9 being adjusted as shown in Fig. 4, when a load is to he discl'iarged.
At each end of the scow, mainly below the decks B, a ratchet and lever rigging is located, which is designed to facilitate the tiltingof the tables G, when this is desired. The mechanism for each end of the scow consists essentially of a horizontal shaftp loosely held in bracket boxes 1) affixed upon the end wall E, said shaft having a worm 19 formed on it near each end. Preferably the shaft 19 is made separable at its longitudinal center, and there joined by a pair of coupling heads 13 which are bolted together, thus holding the shaft sections aligned, and are adapted for detachment to permit the independent rotation of the shaft sections. On the projecting ends of the shafts 8, similar worm wheels r are secured, these wheels having a diameter and pitch of teeth which will adapt them to have a meshing engagement with the worms 13 Between the worms and coupling heads on each shaft section 19, a ratchet wheel .9 is secured, and adjacent to each of said wheels a lever to is loosely mounted on the shaft, so as to permit a pawl u on each lever to interlock with the teeth of the ratchet wheel it is opposite, and thus afford means to rotate the connected shaft sections by a manipulation of one or both levers. By preference, a metal trestle frame composed of two legs o and a cross plate 4;, is provided for each end of the scow to support the ends of the longitudinal shafts e, and ends of the transverse shafts p,
IIO
suitable boxes being secured on the legs and cross plates to effect such asupport; the pieces 0, 12, being respectively secured by bolts to the vertical walls E and also to a proper bedplate E near the bottom of the hull.
As shown in Fig. 1, the ratchet wheels 3 are furnished with teeth similar to ordinary cogs in a gear wheel, which will allow the pawls n, which are L-shaped and pivoted to the sides of the levers u, to be rocked on their pivots and engage the ratchet Wheels so as to rotate them in either direction, and thus tilt or raise the tables to a level position. as required.
Another provision for the support of the tilting tables consists of the longitudinally extended wire ropes, or chains to, that are located in the hull of the scow and extend par allel and near to its side walls, said ropes passing through the batten bars h, as shown, the ends of said ropes being secured to the drums of the winches w that are placed on the decks B at proper points to be adapted for efficient service.
When the tilting tables are to be maintained with their platforms g in the same horizontal plane, the winches w are manipulated to draw the ropes w taut, which will serve to raise the tables to the same level, and so retain them until the winches are relaxed, when the weight of the imposed tables will cause the depression of the outer edges of the platforms 9, and also induce the unsupported ropes w to unwrap a portion of their. length from the winch drums; such a result following the proper manipulation of the levers u in a proper direction to tilt the tables, as before explained. The ropes to maybe used with the arch braces 71, or said devices may be employed separately, as may be desired.
It will be seen that when the scowis loaded by imposing dirt or other material on the platforms-g, so as to fill them partly or completely and the scow has been moved to a point of discharge, the load may be dumped from both sides of the scow at the same time, if the shafts 19 have their sections coupled together, and the levers u are vibrated so that the pawls u may rotate the ratchet Wheels they engage, and thus communicate a rocking movement to the tables G, pitching them into the inclined position indicated in Fig. 4.
The provision of the worm gearing hereinbefore described, and manner of connecting the same to the tables Ghafiords means to retain the tables level or inclined until the levers u are manipulated, the connections with the tops of the stanchions being provided to relieve the gearing from strain. Should it be desired to discharge the load from the tables G successively, the shafts p are separated at their centers as before explained, which will permit one table to be rocked without affecting the other table, so that by first discharging the load from one table and then changing the position of the scow so as to bring its other side opposite the dumped load, the contents of the loaded table can then by a manipulation of its independent gearing, be precipitated directly upon the material dumped from the other table.
Having thus fully described my invent on, I claim as new and desire to secure by Letters Patent- 1. In a dumping scow, the combination with a hull having a flat bottom sloped upwardly to meet decks at the ends of the hull, and provided with a main deck sloped oppositely toward the sides of the hull, of tilting tables on the level part of the main deck adapted to tilt toward the sloped portions of said main deck, and a lever, ratchet and worm gear mechanism connected to a rocking shaft on each table for rocking the tables, substantially as described.
2. In a dumping scow, the combination with a hull, two similar tilting tables thereon, and devices adapted to retain the tables level on the hull, of a ratchet, lever and worm gear mechanism at each end of the hull adapted by manipulation to tilt the tables when the retaining devices are released, substantially as described.
3. In a dumping scow, the combination with a hull, two similar tilting tables thereon, and stanchions on the median line of said hull, of two tables, L-shaped in cross section and adapted to rock on the deck of the hull toward or from the stanchions, stay rods adapted to hook fast to the tops of said stanchions, and mechanism for rocking the tables into level or inclined positions, substantially as described;
4. In a dumping scow, the combination, with a hull having a main deck level atits center and oppositely inclined toward the sides of the hull, and two similar tilting tables 011 said main deck, of curved braces working through the inclined portions of the deck and adapted to support the tables in a level position, by the application of wedges at their ends and ratchet, lever and worm gear mechanism for rocking the tablesand adjusting them level or inclined, substantially as described.
5. In a dumping scow, the combination, with a hull having a main deck level at its center, and oppositely inclined from the edges tially as described.
