ALPHONZO B. BOWERS, OF SAN FRANCISCO, CALIFORNIA.
DREDGING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 364,571, dated June 7, 1887.
Original application filed December 9, 1876.
To all whom it may concern.-
Be it known that ALPI-IONZO B. BOWERS, of San Francisco, California, civil engineer, have invented certain Improvements in Hydraulic Dredging Apparatus, of which this is a specification.
It is a seventh division of the application filed by meDecember 9, 1876, and renewed April 16, 1879, being portions thereof shown in Figures 3, 6, 7, 8, 9 of the original drawings, and in accompanying Figs. 1, 2, 3, with details of construction more fully set forth in my application filed June 30, 1883, Serial No. 99,678,
of which also, to this extent, this application is a division.
It consists, mainly, in a rotary excavator provided with a telescoping suction-pipe and a telescoping excavator-shaft actuated by a prime motor other than that which actuates the pump or pumps; also, in devices fordisintegrating the spoil after its entrance into the excavator and before reaching the pump or pumps.
Fig. 1 is a plan of this apparatus. Fig. 2 is one form of the lower end of the telescoping section of suction-pipe. Fig. 3 is a longitudinal section through the excavator and lower end of the telescoping section of suction-pipe around which said excavator revolves, with a view of the spikes, cutters, or teeth secured to the interior of the suction-pipe and to the excavator-shaft. V
B B are large pumps for raising and discharging the spoil; As each pump requires I much power to actuate it, they are preferably driven each by its own set of directacting independent engines. O is a suction-pipe connecting the pump or pumps with the excavator.
D is one form of the lower end of the tele- As here shown it is identical with the inner chamber, D, described and claimed in Letters Patent No. 318,859, issued to 'me May 26, 1885, for.
the first division of the original application. 7
E is a rotary excavator, and in the form here shown is substantially the excavator described and claimed in the aforesaid Letters Patent, and is driven by its own independent engines acting directly upon the crankshaft that carries the pinion T.
the excavator-shaft.
(No model.)
To accommodatethelongitudinal movements of the telescoping section of suction-pipe, provision must be made for a like movement of As the shaft that carries the pinion 'I precludes the common device of a square or feathered shaft sliding through its driving-wheel, the excavator-shaft must be provided with a telescoping section; and to retain the full strength of this shaft it must telescope into an enlarged section. As this enlarged section would impede the flow through the suction-pipe, it is preferably placed out side thereof in the fork of said pipe, as shown.
F is a longitudinal section through a portion of the excavator-shaft into which a square section of said shaft with rounded corners telescopes simultaneously with the telescoping of the suctionpipe. The mode of preventing longitudinal movementof this section and the gland for excluding air being'of the ordinary construction, is not here shown.
J J are the serrated or chisel-teethed knives described and claimed in the Letters Patentfor the first division hereinbefore specified. 7
K K are spikes, cutters, or teeth, that may be secured to the interior of the suction-pipe or to the inner chamber, and K K are similar devices that may be secured to the shaft of the excavator for the purpose of disintegrating the spoil.
S .is the telescoping section'of the suctionpipe. It is here shown in combination with the spiral spring a and slide-rods't t, described and claimed'in the third divisional application filed April 29, 1885, Serial No. 163,888.
T is a disengaging-pinion sliding 011 the crankshaft of the engine or engines that actu ate the excavator, and is constructed and handied in the usual manner. This crank-shaft and its engines perform no duty other than that of actuating the excavator, in order that the speed of the latter may be regulated by the throttle-valve or governor without varying the speed of other parts of the machine.
In this seventh division I claim- 1. In combination, a rotary excavator and telescoping driving-shaft.
2. In combination, a rotary excavator with inward delivery through itself, and a telescoping driving-shaft.
3. In combination, a rotary excavator, telcscoping suction-pipe, and telescoping drivingshaft.
4. In combination, a rotary excavator with inward delivery through itself, a telescoping suction-pipe, and a telescoping driving-shaft.
5. In combination, a rotary excavator, telescoping suction-pipe provided with the spiral spring u, and a telescoping driving-shaft.
6. In combination, a rotary excavator with inward delivery through itself, a telescoping suction-pipe provided with the spiral spring a, and a telescoping driving-shaft.
7. In combination, a rotary excavator, atelescoping suction-pipe provided with the sliding guide-rods t 1, and a telescoping drivingshaft.
8. I11 combination, a rotary excavator with inward delivery through itself, a telescoping suction-pipe provided with the sliding guiderods t, and a telescoping driving-shaft.
9. In combination, a rotary excavator, telescoping suction-pipe provided with spring a, guide-rods it, and telescoping driving-shaft.
10. In combination, a rotary excavator wit-h inward delivery through itself, telescoping suction-pipe provided with spring a, rods 1 1, and a telescoping driving-shaft.
11. In combination, a rotary excavator, suction-pipe,pump,and separate prime motors for actuating the excavator and pump.
12. In combination, a rotary excavator with inward delivery through itself, asuction-pipe,
pump, and separate engines for actuating the excavator and pump.
13. In combination, a rotary excavator, telescoping suction-pipe, pump, and separate engines for actuating the excavator and pump.
14-. In combination, a rotary excavator with inward delivery through itself, and a device for disintegrating the spoil after its entrance into the excavator.
15. In combination, a rotary excavator, suction-pipe, and pump, and a device for disintegrating the spoil between the excavator and pump.
16. In combination, a rotary excavator with inward delivery through itself to a suctionpipe, a pump, and a device for disintegrating the spoil after its entrance into the excavator and before reaching the pump.
17. In combination,a rotary exeavator,'driving shaft, suction pipe provided with the spikes, teeth, or cutters K, and a pump for raising and discharging the spoil.
18. In combination, a rotary excavator, a driving-shaft provided with disintegrating devices K, a suction-pipe, and a pump for raising and discharging the spoil.
In witness whereof I hereunto affix my signature in the presence of two witnesses.
