I POLE-ERECTING APPARATUS.

Application med umn as, 1907. serial No. 364,957.'

Be it known that I, JOHN M. HUMIsToN, a citizen of the United States of America, and a resident of Berwyn, countyf'rof Cook, and State of Illinois, have invented a new and useful Improvement in Pole-Erecting Apparatus, of which the following is a specification. i

My invention relates to a mechamcal means for excavating holes in the ground for the setting of posts and poles.

The object of the present invention is to provide an efficient and flexible means for' excavating holes for the reception of poles aml. to provide a means for erecting the o es. p Furthermore, the invention has for its ob ject the provision of a mechanical apparatus, the several parts of which will be driven by a prime mover, the power of l which may be conveniently appliedto the locomotion of the equipment, tothe excavation of holes and'to the erection ofpoles.

With this and other objects in view, the present invention consists in thecombination and arrangement of parts as will be hereinafter more fully described, shown in the accompanying drawings and particularly pointedout yin the appended claims, it being understood that changes' in the form, construction, size and minor details may be made within the scope of the claims .without departing from the spirit or sacriicing any of the advantages of the invention.

` Inthe drawings, Figure 1 is a plan of an apparatus constructed and arranged inaccordance withthe present invention;

vFig. 2 is an elevation of the same device;

Fig. 3 is a detail of a portion ofthe auger; Fig. 4 .is a detail of a clutch on the auger;

Fig. 5 is a plan det-ail of the steering` knuckle arrangement; Fig. 6 is a front A elevation vof the steering knuckles and axle, 45

and showing the axle with the bolster carrying the wagon-bed which is suspended therefrom; Fig. modified style of construction of steering knuckles and axle'.

. Like characters of reference designate corresponding parts in all the figures ofthe drawings,

" For convenience` in transportation, thel present apparatus has a wheeled platform or' body 1, hung from rear wheels '2 and frontwheels 3,Ithe front wheels being pro- 7 is a front elevation of a vided with steering knuckles 4 connected to the steering lever 5 which operates both -knuckles simultaneously through the conhoist 13 with a piston and piston -rod 14.-

By an admission of air to this cylinder hoist through the valve 1.5, the piston is moved, drawing rod 14 which in turn .pulls rope 17 through pulleys 12, which rope is attached to a regular rotary air drill 18,

connected through an' automatic val-ve 19 with'the air supply through the hose 20. Thls rotary air drill-has a rotating element and a stationary body; the rotating element 1s coupled to and operates an auger 21 which has a telescoping stem 22, shown in detail in Fig. 4. By means of the dogs 23 of the clutch 24, the inner shell 25 of the auger 21 may be locked at any one of several predetermined points of the outer shell 26.

The appliance may be propelled either by transmitting power from the prime mover to the back wheels 2 through any` suitable one'of the well-known transmission gears, or by bitching draft animals to the frame 1 of the rig. he boom ,may be raised and' lowered` by means of rope .26 working through tackle 27, which, is only shown 1n Fig. 2, being omitted from Fig. 1 for the sake of clearness,

lIn operation the gasolene engine vgenerates power, taking gasolene from the tank 28'through ipe 29 through feed pump 301 through car ureter 31 into the cyl1nder32. The im ulses obtained from the explosions rotate y wheels 33 and ulley 34 which is attached to the same sha t 'as y wheels 33. The cylinder of the engine is cooled by -water drawn from tank 35 through pipe 36 and returned to the tank through p1pe 37 The belt 38 transmits the power through-the com-v bination fly Wheel and pulley 39 to the crank shaft 40 of the air compressor of 'which 41 jis the cylinder, 42 the guide rods, 43 the Specivcation of Letters Patent. i Patented Jan. 9, 1912.

cross-head, 44 the base frame, 45 the piston rod and 46 the connecting' rod. Air is drawn into the cylinder of the air compressor through an 4automatic regulator 47 through the pipe 48 to the cylinder 41. It is ejected after compression through the pipe 49 leading to T 50. From this T all of the compressed air flows through pipe 51 to the air tank 52. The tank pressure bears against a small piston. in the automatic regulator 47, which pressure is resisted by an adjustable spring in such a way that when the tank pressure rises above a certain value the supply of airis automatically stopped and the compressor continues to rotate and have its parts move lwithout compressing any air. From tank 52 -air is led through th`e pipe 53 t0 theT 54 at which point a branch hose 55 takes a supplyy of air to the cylinder of the hoist 13. Beyond 54 is the valve 56. From that point air passes through the hose 20 to the automatic valve 19 in the rotary drill 18. The cylinderof theair vcompressor is cooled by drawing water from the tank 35 through pipe 57 'then-through the water jacket of the cylinder 41, then returned through pipe 58 to the water tank 35.

In operation, the appliance is moved to a convement point close to where the hole is tobe dug. It may be moved either by furnishing its own motive oweror by being drawn by draft" animali; fastened to the frame 1 b a line of suiiicient length so that these dra t animals may be out of the way of the boom and all its gear. The appliance is steered to the proper location by anjoperative turning the iront- Wheels by means of the steering lever'5. JllVhen it isv in the proper position ytheboom is adjusted 'by either a horizontal 'or a vertical motion,v or

' both, until the drill and auger are suspended immediatelyover the point' where it is d'e sired to dig the hole. The 4motive `power 1s in .continuous operation, compressing airat all times except whengoverned by the regulator on the air compressor. -When 'everything-is ready. an operative braces himself jon; the ground and grasps the drill' 'by the handle-'59..and thevalve' 19,- a helper at the same'timefgrasping thev handle 59 which may bev asA much. longer -thanshown on thedrawing as necessary', and steadying the drill bythe main'body with the other hand to assist the operative in holding the stationary elementofthe drill against the thrust caused bythe operation of the auger in the ground..

The operative admits air to the Vdrill which compels the rotation of the rotating element and vcauses the auger 21 to rotate. The auger 2l rotates and carries itself down in the ground until iti is fullnof excavated material,

when the operative. releases valve 19 which automatically closes, shutting olf the air supply, and gives the signal to another operative w o by the manipulation of valve 15 of the cylinder hoist- 13 raises, by means of Jthe rope 17, the drill 18 and auger 21 out of the ground with its load of excavated material. This operative at the hoist then swings the boom 11 slightly to one side, and the operative at the drill shakes the excavated material out of the auger; The operative at the hoist then swings the boom back and by manipulating the hoist valve 15 lowers the auger into te hole `for another operation. This series of actions is repeated until the hole is excavated to a depth where it is necessary to lengthen the stem of the auger to permit the. auger to go deeper and yet -retain for the operatives convenient and etlicient manipulation of the auger and drill.

' The operative then, by moving handle 7 0 in Fig. 4, moves the dogs 23, Fig. 4, so as to disengage'them from the seating holes in the inner shaft 25; then he lengthens the stem of the auger to a suitable point, when he' releases lever so that dogs 23 will engage other holes in the inner shaft 25, maintalning rigidity in the auger stem at a different length. The operative then admits air into .the drill and repeats the operations de- ;scribed hereinbefore until the hole is of the ydesired. ultimate de th. The valve 15 of the air hoist 13 is le t so that the auger is at va sufficient height to clear the ground, and a signal is given, either to the driver of the jdraft animals or to the attendant who ope@rates the clutch connecting the prime mover with therea'r Wheels,` and the entire appliyance is moved to the place Where it is desired jle excavate'thev next hole, and the cycle of operations is repeated.

In case it is desired to erect the pole at the same time, the drill 18 is disengaged gfroln the hook 60 on the rope 17 and the -hookfis fastened into a sling of rop'e about .the pole and' `the pole is raised by means of the cylinder hoist 13, manipulated through the valve 15, until it is at a suflicient height when itv guidedinto the hole by a man stationed at the vproper point 'for that pur,- gpose', the valve l5 being properly.,.manipulated to -allowl .the pole lto be llowered into Sthe'hole. The clutch Qauger stem shown in Fig. 4 may be further explained by noting that 671 is a collar on l operating thel telescoping the outer tube 26 ,l 68 is' alug fastened on Vsaidgcollar; 69 is a rotatable pin passing' through said lug';'70is a llever 7 1 is a collar slidable along the rod 72 and swiveledin thelever 70, and byraising the lever 701upward, as shown on the drawing, the rod 72.`

is raised, pulling the 4spring steel strap 73 away from thetube 26 and at the same time raising the dogs 23 and ydisengaging them from the holesinrthe innerA tube' 25.

With respect-to Figs. 5 and 6,.the` plan and elevation respectivelyjof the front axle, 4 4 are the recessed steering knuckles, hav.-

ing axle recessed between pivots to insure ease of manipulation, rotatable horizontally in the ends ofthe `axle frame 74; 4-4 are vertical pivots of the recessed steering knuckle, placed as close to the plane of the wheel as possibleand arranged with respect to the axle so that a plane through these pivots intersects the bearing surface of said axle, to secure ease and certainty in steering; 4 is the axle attached to the knuckle ata point recessed with respect to the steering lmuckle pivots 5 is a lever rotatable about the shaft 7 5, which is braced to the axle by the brace 76, and transmitting motion through the rod 77 to the connecting rod 6v which transmits motion and 'insures correspondence of motion through the steering A of work exists, I prefer to use the two sepaknuckle lever' 78 to the steering knuckles 4.-4; 79 are steel rods swinging the braced platform 80 from the bolster 81 andvbeing attached to same through the saddles 82 and nutsg83; 84 are clamps fastening the bolster to the axle frame work. Fig. 7 shows another form of construction of this front axle.

I preferto Vemploy the device illustrated and described herein for the purpose o f excavating the pole holes only, allowing another simpler device for raising and 'setting the poles in the holes so dug to follow.

Instead of employingv this more complete schemeof two coperating devices, I sumbit the Ydevice of Fig. 2,'having the hook 60 for detaching the drill and auger from the derrick, thus temporarily converting the hole digger to' be a pole erector. In usingthis single device for both purposes, the economy of operating is reduced in the consideration of the -feature of idle equipment, since during thel erection ofjthe pole the entire excavating apparatus.. remains unproductive;y

some increase of efliciency, however, tends to counterbalance this by reason` of having toy set but the one device to excavate,'and to erect the pole. Where a suficient quantity rateedevices," keeping the device of Fig. 2 continuously operating in excavating and keeping lthe pole erecting device continuouslyoperating'in erection of poles; however,

A anytask of limited extent, it will be found erecting device and use'the device of Fig.- 5

' cavator and erector.
