A. B. BOWERS. DREDGING APPARATUS.
Patented Sept. 17, 1889.
UNlTED STATES PATENT OFFICE.
ALPHONZO B, ownns, or SAN FRANCISCO, CALIFORNIA:
DREDGIING APPARATUS.
fiPEGIFIGATION forming part of Letters Patent No. 411,183, dated September 117, 1889.
Original application filed December 9,
1876. Divided and another application filed April 27, 1886. Again divided and this appliesdon filed May 17,1887. Serial No. 238,513- (No model.)
To all} whom it may concern.-
Be t known that I, ALPHONZO B. Bownns, of San Francisco, California, civil engineer, have invented certain Improvements in Dredging l 2 5 ate the excavator. Fig. 2 is a side view show-' Apparatus, of which this, with the accompanying drawings, is a description.
It is a fifth division of the third division filed April 27, 1885, or the, eighth division of an application filed by me December 9,1876, and renewed April 16, 1879, being for portions thereof shown in original figures 7, 10, 18,19, 20, and .21. Y
It consists, mainly, of a non-rotating'excavating implement attached to a suction-pipe,
in combination with a suitable fender projectin g below said implement to enable it to ride over obstructions. A
It also consists, in part, of the combination, with said implement and pipe, of a' rotary fender; also, in the combination, with said implement, pipe, and rotary fender, of an auxiliary rotary'excavator secured to and revolving with said fender.
Figure 1 is a plan of this apparatus, showinghow two endless chains may be used toactuing how said excavator may be driven with a single chain. Fig. 3 is a vertical section 4 through the lower end of the suction-pipe and excavator. Said Figs. 2 and 3 show the suc; tion-pipe atan inclination nearer the vertical than will normally be the case, the proper inclination being such as will bring the peripheral fenders on E below the level'of the cutting-edge d Fig. 4. shows the cutting-edges, chain-wheel, and bearings of the excavator. Fig. 5 shows the mouth of the suction-pipe with its screening-bars, scraper, and the brackets and bearings that support the excavator.
,Fig. 6 is a reproduction of original Fig. 18,
Fig. 7 of original Fig. 22, and Fig. 8 of a portion of the driving-shaft oforiginal Fig. 7 corresponding to shaft F, in Fig. 1.
A is a pump for raising and'discharging spoil.
. B is a gland through which an air-tight con nection is made between the swinging and stationary sections of suction pipen suction-pipe.
carry to the O is an outboard section of suction-pipe. It swings c, the former being an elbow of said pipe, and the latter either an elbow or otherwise, in accordance with the number of pumps used.
c is an eye, to which the hoisting and lowering device may be attached.
in'a vertical plane on trunnions 0 5o D is the outer end, and d the mouth, of the As here shown, this outer end is enlarged, flattened, curved around the excavator, and provided with a screeningdevice, preferably consisting of the bars (1', to admit spoil but exclude material too coarse to pass through the raising and discharging apparatus. It is also provided with a scraper d on the lower side of the suction-pipe.
E is a rotary excavator with outward delivery to the mouth of the suction-pipe; As
.here shown, in Fig. 1 it is provided with six and in Fig. 2 with four opencentered disks e. Thesedisks are secured to arms -e'- radiating from central. hubs keyed to the excavatorshaft. Between the central open-centered disks, Figs. 2 and 4, is a chain-wheel e Between the central and end disks, and secured thereto, are cutting-edges e, which may be identical with the detachable knives S described and claimed in the first divisional patent, No. 318,859; and back of these edges, and secured to the arms e, are scrapers e, that mouth of the suction-pipe the spoil cutby the knives e These knives are for cutting clay and similarly tenacious material, and should be removed with the drivingchain, also, whenthe excavation is in sand or gravel, the radial devices 6 and scraper (it being sulhcient and preferable for such eas ily-disintegrated material. This excavator may be actuated by an endless chain a or in any other suitable manner, and as here shown is placed transversely to the pipe and in front of the mouth thereof, This excavator also serves as a fender for the protection. of the, scraper d.
F is a short shaft between and .in line with the axes of the trunnions cc, on which may be placed chain-wheels f for actuating the endless chains and excavator shown in origim1 Fig. 18,1-eproduced in Fig. 6; or 11 m carry a pinion, as in original Fig. 7, present Fig. 8, to drive the excavator bysu itable shafting and gearing,as indicated in original Fig; 22, present Fig. 7.
G is a gear or other suitable device for act uating the shaft F.
H are guide-sheaves for the endless chain. As here shown,the dredge works with aforward feed in line with the longitudinal axis of the hull- By suitably changing its form and placing the suction-pipe in front instead of in the rearof the excavator the feed would be in the opposite direction.
