WILLIAM I. KING, OF SAN FRANCISCO, CALIFORNIA.
EXCAVATOB.
To all whom it may concern:
Be it known that 1, WILLIAM P. KING, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Excavator, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.
This invention relates to an excavator especially adapted to the digging of cellars where buildings are to be constructed, although it may be used simply for ditch work if so desired.
An object of the invention is to make a portable self-contained machine which may be hooked on to a wagon and pulled from place to place when a given job is finished.
Another object of the invention is to provide a machine which is capable of varied classes of work and which always remains upon the solid ground as the work proceeds.
Another object of the invention is to provide means whereby the material excavated will be discharged into a bin at a suitable height for a wagon to drive under to load, thus reducing the expense of the handling of the material.
Other objects of the invention will appear as the description proceeds.
I am aware that there are many modifications of this invention, but one of the embodiments thereof is shown in the drawings in which the same reference numeral 1s applied to the same portion throughout.
Figure 1 is a side elevation of the complete machine, a portion of the bin being broken away for purposes of illustration, Fig. 2 is a front elevation of the turn table head-gear for driving the excavator buckets, Fig. 3 is a side elevation of the machine looking in the opposite direction from Fig. 1, and with a portion of the storage bin broken away for purposes of illustration, Fig. 4: is a broken view partly in section of the turn table and illustrating the operation of the mechanism which forces the excavator away from the truck, Fig. 5 is an end elevation of the excavator looking at the end of the machine on which the ex cavator chain is mounted, Fig. 6 is a view of the clutch and operating mechanism for operating the turn table in either direction, Fig. 7 is a side elevation partly in section of a portion of the turn table supporting Specification of Letters Patent.

ring and one of the supporting rollers, Fig. 3 is an end elevation of the machine lookmg in the opposite direction from Fig. 5, with a portion broken away for purposes of illustration, Fig. 9 is a view partly in section showing the turn table king bolt, and Fig. 10 is a plan view of the receiving hopper for the secondary conveyer.
The numeral 1 indicates the bed of a low truck having rear wheels 2 and front wheels 3. The front wheels are movable in a well 7 known manner, and the truck may be moved from place to place by means of the tongue 1, said tongue being removed from the truck when it is desired to load a wagon under the Storage hopper.
Supported upon the truck at one end thereof is a turn table 5. This turn table has a downwardly extending flange 6 at its outer edge which rests upon suitable grooved rollers 7, of which there may be such a number as may be necessary to adequately support the turn table. This turn table is rotated by means of a short segment rack 8 engaged by means of a small bevel wheel 9 on a shaft 10.
The turn table supports two vertical posts 12 and 13, which posts are suitably connected at their upper ends by means of a cross bar 14 bolted thereto, and which cross bar has an eye-bolt 15 connected with the guy rod 16, said guy rod being connected to an eye-bolt 17 at the front end of the truck. Pivotally supported on the turn table adjacent the base of the posts 12 and 13 is a boom having side members 18 and 19. These side members are suitably slotted at their upper ends to receive sliding journal boxes 20 and 21.
At the upper end of the boom there are two bracket frames 23 and 24, which frames support a shaft 25 carrying a. grooved roller 26. A cable 27 extends over the grooved roller 26. A cable 27 extends over the grooved roller 26 and is connected with the elevator ladder 28 by means of the V shaped member 29. At the other end of the cable it is passed around a drum 30 having a crank 31 and ratchet wheel 32 for supporting the elevator ladder at any given height.
Passing through the journal boxes 20 and 21 is a shaft 35, which shaft passes through links 33 and 34. connecting the boom and main supports 12 and 13. The shaft 35 has sprocket wheels 36 and 37 on the ends thereof. Suitable. chains 38 and 39 pass over these sprocket wheels and drive the shaft 35, said chains passing over sprocket wheels 40 and 41 on the main supporting mast. The main supporting mast carries a horizontal shaft 13 which supports and rotatesthe sprocket wheels 40 and 41, and it also carries a bevel gear 1 1 in mesh with a bevel gear 15 on a vertical shaft 16, the latter receiving power from a suitable pulley 47 at its lower end.
The pulley 4:7 is driven by means of the belt 18, which belt also passes over a pulley 19 on a shaft 50, the latter shaft being supported on a frame 51 near the middle of the truck. The frame 51 is suitably braced and also supports a shaft 52, which shaft is driven from the shaft by means of a chain 53. Mounted upon the truck is a motor 54: having a belt 55 extending over a pulley 56 on the shaft 50. The shaft 50 also carries a sprocket wheel 57 for driving the chain 58 which passes around the sprocket wheel 59 on the shaft 60 of the secondary conveyer.
Returning now to the excavator ladder 28, it will be seenthat it is provided with chains 61 having a series of buckets 62 thereon. These chains pass under suitable sprocket wheels on the shaft 63 at the bottom of the ladder, and move in the direction indicated by the arrow, Fig. 1, the truck being pulled back to the left, Fig. 1, as the excavator nears the rear wheels 2. In order to be able to move theexcavator ladder away from the turn table and to determine its feed into the bank of material to be operated upon, two pusher bars and 70 are provided, each of said bars having rack teeth at one end and having side plates 71 and 71 at each side of the excavator ladder to hold it in the proper line. These bars the ends of which bear upon the sides of the rail 28 are connected together and are forced outwardly by operating the hand crank 72 on the turn 1 table post 12, said crank being suitably connected with a sprocket wheel 73 around which passes a sprocket chain 74 extending around a sprocket wheel 75.
The sprocket wheel 75 is carried by a shaft 76 on the top of the turn table and it also I has two gears 77 and 77 in mesh with the two pusher rods. The pawl 78 enables the pusher rods to be held in any given adjustment. At the top of the excavator there are two brackets 80 and 80 supporting a hopper 81, into which hopper the excavator buckets throw the material picked up by them.
This hopper has a suitable flexible tube 82 extending therefrom which tube carries the material elevated back into the receiving hopper 83 supported on the post 13. This receiving hopper has a link 84: which supports its front end and enables it to be the conveyer 87 discharges.
At the lower end of the receiving hopper 83 there is a short tube 85 leading into a hopper 86 over the conveyer belt 87. The conveyer belt 87 operates in a chute 88' which'is supported upon posts 89 and 90, the latter post being suitably braced at 91 to Withstand the pull of the sprocket chain 58.
Supported upon the front end of the truck and upon the post is a bin 92, into which 7 This bin has braces'93 and 94: connecting it with the post 90 and truck respectively. The front of the bin is previded with the. usual gate boards 95 and 96 to enable the material to be discharged therefrom into a wagon when neces sary.
In order to enable the to be movedin a circle about the center of the turn table, which turn table is held down by means of the king bolt 97, a chain 98 passes over the sprocket wheel 52 and over the sprocket wheel 99 on the shaft 100.
This shaft 100 is supported upon posts 101, 102 adjacent the side of the turn table, and it carries belt pulleys 103 and 104 over which belts 105 and 106 pass, the latter being a crossed belt to give a reverse direction of movement of the turn table. These two belts pass over pulleys 108 and 109 respectively, which pulleys are carried by a shaft 10 and have clutch. members thereon to be engaged by the clutch collar 111 whenever it is desired to rotate the turn table in either excavator ladder 28.
direction. This shaft 10 has thesmallbevel gear 9 in mesh with the segment rack 8 on the turn table so that it may be driven thereby.
. In operation the apparatus is taken to the most distant portion of the ground to be excavated and the excavator ladder is alsuch a direction as to move away-from the.
excavator ladder which will permit it to incline therefrom at a sharper angle, thus bringing the series of buckets against the ground and enabling it to digout the soil. The materials picked up by thebuckets 62 are dumped into thehopper 81' from which point they fall down the chute 82 into the hopper 86 and are taken from that point to the bin 92 from which they are discharged into suitable wagons. The bin 92 is of course made large enough to store considerable material therein so'that' there need be no delay in the filling of the wagons. The pressure brought upon the soil to be excavated is determined by the raising or lowering of the cable 27 andby regulating the inclination of the ladder 28 with respect to thev means of links 3st, and that while, the exca vator ladder may be moved up and down the angle of the boom is varied only a small amount, because the ends of the links travel along the slots in the .boom. The clutch member 111 is shifted from one position to the other by means of a shifting lever 111 which rests upon a supporting bar 111*, the latter having suitable notches to hold the lever 111 in the engaged or disengaged posi-' tion as desired.
Having thus described my invention What I claim as new and desire to secure by Let- 1turn table, links connecting the boom and ows:
1. In an excavator, a truck, a turn table thereon, a mast and a pivoted boom on said turn table, links connecting the boom and mast for the support of said boom, an endless chain excavator supported by the boom, a vertical shaft axial with the turn table, a pulley at the end of said shaft, and means at the upper end of said shaft and extending along said links to deliver power to the end- Copies of this patent may be obtained for less chain excavator, substantially as described.
2. In an excavator, a truck, a turn table thereon, a mast and a slotted boom pivotally supported upon said turn table, links connecting the upper portions of the mast and boom, journal boxes sli'dable in the slotted boom, a shaft passing through said journal boxes, means extending along said links to drive said shaft, an endless chain excavator supported upon said shaft, and a cable passing over the top of said boom for raising and lowering, the links and endless excavator and changing the position of the boom.
In testimony whereof I have hereunto set my hand this 26 day of March A. D. 1913, in the presence of the tWo subscribed Witnesses.
