HENRY II. LYNCH, OF SAN FRANCISCO, CALIFORNIA.
DREDGER.
SPECIFICATION forming part of Letters Patent No. 365,140, dated June 21, 1887.
Serial No. 300.166. (Ne model.)
To all whom it may concern.-
Be it known that I, HENRY H. LYNCH, of the city and county of San Francisco, State of California, have invented an Improvementin Drcdgers; and I hereby declare the following to be a full, clear, and exact description of the same.
My invention relates to certain improvements in apparatus for excavating or dredging; auditconsists, mainly, in a novel construction of excavating blades or flanges arranged either spirally or straight, with suitable supporting rings and disks, and a mechanism by which it may be rotated, in connection with a suction-pump,by which the material loosened and excavated by these flanges may be removed as fast as it is excavated.
Referring to the accompanying drawings for a more complete explanation of my invenlion, Figure 1 is a side elevation of my exea vator. Fig. 2 is a longitudinal vertical section. Fig. 3 is an end view. Fig. 4t is atransverse section taken in the plane at right ancavating buckets or openings upon its periph cry, in combination with a suctioirpipe which opens into the drum, and by which the material is removed as fast as it is introduced into the dru m by the buckets. I have found that in many classes of work these buckets cannot supply an amount of material sufficient for the suctioirpipe, and when this is the case agreat quantity of water will be drawn in and a comparatively small amount of solid material. In order to overcome this objection I have discarded the drum entirely, and I employ long curved flanges or diggers A, which are made of boiler-iron or steel riveted or secured to gether,and supported by stronginterior rings, B B, to which they are bolted. In the present case I have shown these digging-flanges attached to the rings,so as to form spirals around the circumference of the structure, and the lower ends are curved inward, as shown more clearly in Fig. 2, and are riveted or be] ted to a circular disk, D, which has a strong central hub, and is bored out to receive the lower end of-the drivingshaft E. The upper end of the excavator has also a central support or head,
F, through which the driving-shaft passes, and the whole is supported upon an inclined ladder or frame which is hinged to ascow or float, so that the lower end maybe raised or depressed to bring the excavator into contact with the earth or material which is to be dug up.
YVithin the structure forn'led by the exeavating-flanges and sup )orting-riugs is a hood, K, which-terms an extension above the suction-pipe,through which the material is drawn as it is excavated. The suction-pipe passes through the upper stationary head or disk, F, before described, and through which the central drivingshaft also passes, and. the hood is placed relatively to the position of the excavator when at work, so that its open side will be presented toward the lower side of the excavator. The material which is loosened up by these spiral excavating-flanges falls into the interior upon the top of and around the hood, and the constant suction through the pipe G (which is produced by the pump connected with its upper end, but not shown in the present case) will withdraw its material as fast as it is supplied. The stationary head or disk F, through which the driving-shalt and the suction-pipe pass,is strongly secured to the lower end of the timbers II, which form the ladder upon which the excavator is carried.
I is a man-hole plate covering an opening through the upper end of the excavator, and through which access may be had to its interior whenever necessary.
In connection with these excavating blades or flanges I employ also cutters or diggers J, which are in the form of curved loops or T- shaped plates of steel bolted to the framework between the excavating-blades and at suitable points, so as to project slightly beyond the edges of the blades or flanges. These T-shaped cutters serve to loosen up very hard or tenacious material and prepare it to be taken in by the excavating-flanges, and they serve also to protect these flanges from injury by stones or excessively hard material which may be encountered in digging.
The edges of the excavatingblades or flanges may be serrated or provided with teeth K,projecting beyond the blades. These teeth are riveted or otherwise secured upon the blades in a substantial manner.
Having thus described my ii'ivention, what ICO - I claim as new,and desire to secure by Letters Patent, is-
1. In an excavator, the shaft, the supports forthe blades or flangesextending circumferentially about said shaft and'at a distance therefrom toform rings, cutting blades or flanges secured at different points on said rings, said blades being arranged spirallyon the rings, whereby the material is cut and directed into the interior of the excavator, and a suction-pipeopening into the interior, substantially as-described.
2. An excavator composed of the supports for the cutting-blades extending circumferentially about the shaft to form rings, the disks or end plates, and the flanges or blades bolted to said supporting-rings and projecting from the sides and around the lower end, so as to presentexcavating-edges, substantially as described.
3. An excavator composed of blades or flanges arranged around a central shaft, and
an end disk and interior supporting-rings to which these flanges are secured, in combination with a disk or head secured to a supporting ladder or frame, a suction-pipe passing through this disk and an interior hood, and a driving-shaft extending through the upper head and secured to the lower disk of the excavator, whereby the latter may be caused to rotate, substantially as herein described.
4. An excavator composed of the flaring blades or flanges, an end disk and interior supporting-rings to which the blades arebolted, a shaft extending through and secured to the disk through which power may be applied to rotate the excavator, in combination with a stationary head at the opposite end with flanges, by which it may be secured to a supporting frame or ladder, and a suction-pipe extending through said head and the hood in the interior of the excavator, substantially as herein described.
. 5. An excavator composed of the flaring or scoop-shaped blades or flanges secured to an end disk, and interior supporting-rings, and having a driving-shaft keyed into the disk, as
shown, in combination with T-shaped cutters or loops bolted to the excavator and'extending outwardly beyond the edges. ofthe diggingu flanges, substantially as herein described.
6.-An excavator composed of supportingrings and straight or spirally-arranged plates supported thereby, projecting from the sides and lower end, and an end disk through which V power is applied, as shown, in combination with serrated edges or teeth, substantially as herein described.
In witness whereof I have hereunto set my hand.
