GEORGE W. BAULS, OF CINCINNATI, OHIO.

EXCAVATOR AND LOADER APPARATUS.

Specification of Letters Patent.

Application filed June 17, 1913. Serial No. 774,211.

To all whom it may concern Be it known that I, GEORGE W. Burns, a citizen of the United States of America, residing at Cincinnati, in the county of Hamiltonand State of Ohio, have invented moved by the operation of the engine cradle when it is desired to transport the excavating machine.

Another obj vide an improved support for operating the scoop.

Another object of the invention is to so construct the excavating machine that it may be conveniently transported from one place to another.

With these and other objects in view, this invention consists of certain novel combinations, constructions and arrangements of parts as will be hereinafter fully described and claimed.

This invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a side elevation of the excavator with the inclined plane in an extended position. Fig. 2 is a side elevation of the excavator with the inclined plane in a folded position and with the engine removed from its support. Fig. 3 is an enlarged side elevation of a portion of the inclined plane in the position shown in Fig. 2. Fig. 4: is an enlarged fragmentary plan view showing the inclined plane in an extended position. Fig.

portion of the excavator. Fig. 6 is an enlarged sectional view of the lower end po'rtion of the inclined plane with the scoop at the lower end of the inclined plane.

Referring to the accompanying drawing, it will be seen that this invention comprises a frame providedv'ith supporting'wheels "It also comprises an incline plane leading to a tilting platform so that a scoop may be drawn up the inclined plane onto the plato is a longitudinal section through the rear form and tilt the sameto cause the dirt in the scoop to be dumped into a wagon posh. tioned beneath the platform.

When constructing this frame the plat;

. forms 10 and 11 are first built and are then connected with the support for the tilting platform which will be hereinafter described. Each of these platforms 10 and 11,

which I shall call the supporting platforms, comprlses the side beams 13 having theirends connected by the cross-bars Hand connectedintermediate their length bythe bracing bars15 which carry the bearing blocks 16. Trucks 17 are positioned beneath the platforms lOand 11 and are pivotally connected with the platforms bythe king bolts 18 which pass through the bearing blocks 16 into the bearing blocks, 19. Each of these trucks comprises a side bar 20 which are conect of the invention is to pronected attheir ends by the cross-bars 21 and intermediate their lengthsby the primary section of the bracing bars 22 supporting porting the cross-bars 26.

The forward platform 10 carries the rear supporting standards 27 which are connect- 1 ed with the shorter forward supporting standards 28 by the connecting bars 29. These

standards

27 and 28 carry the crossbars 30 upon which the inner end portion3l' v i j of the inclined plane is rigidly secured,-as

shown in Fig. 5*. Longitudinally extending gulding strlps 32 arev secured to the inner end portion 31 of the primary section of the inclined plane converge. to .guide the scoop and cause'it to leave theinclined plane at the proper point.

The rear platform 11 carries the vertical standards 33 and 34:,which standards are braced by the cross-bars .35. 'Additional braces 36 are provided for the standards 33 to prevent the standards 33 from moving out of thevertical position. It should be noted that the standards 34 together with the cross-bars 35 and diagonal braces 36 form a rectangular support which is hinged to the platform 11 by means of the hinges 371 so that the engine cradle may be releasably held in a raised position.

The engine cradle comprises longitudinally extending side bars 38 pivotally connected with the standards-33 by means of the bolts 39 and connected by meansofthe cross-bars 4O positioned at points through- Patented Nov. 10, 1914.

out their length. A fioorin 41 is built upon the frame formed from tie longitudinally extending side-bar's38 and crossbars 40 and carries a bed 42 for the engine indicated in general at 43. Side rails 44 are provided to prevent danger of persons falling from the cradle. The rectangularsupport is held in a raised position by the securing pin 45', which is passed through one of the flooring boards into the upper bracingbar35 oftho hinged rectangular support. F roman inspection of Fig. 5 it will readily be seen that the hinged support holds the cradle in an elevated position when the-excavator is in use, but when thepin' 45- is removed that the cradlemay be lowered to the dotted line position shown so that the engine may be removed if desired.-

The upper platform connects the cross bars and and comprises the longitudi nally extendingside bars 46 which are connected by the'cross bars 47 and flooring. 48 v This flooring- 48' is only provided at the rear ortion of the upper latform; thus leaving an opening in the forward portion in which openingthe -tilting platform, before referred to, is mounted. Diagonal braces 49 lead from the cross-bars 14 of the platform-11' to the rear bracing bar 47 of the upper platform, thus strengthening the frame and forming guides to prevent the cradle from moving transversely. when being'raised or lowered. The upper platform is also braced by the diagonal braces 49 and 49 Standards 50 extendfromthe'upp'er platform and are connected by the shafts 51 upon which the pulley wheels 52 are mounted. These standards 50 are braced by the diagonal bars 53 which bars have their lower endssecured tothe cross-bars 54 and form supports for the inclined'board 55. This board" 55 together with the inclined side boards 56' form a hopper extending about three sides of the opening: in which the tilt-' ing platform is pivotally mounted. The tilt-' ing platform '57 is' pivotally mounted in the there are provided curved prongs 60 extending' above theupper surfaceof the platform to steady the: scoop and prevent the scoop from sliding from the platform.

The=upper portion of the'auxiliarysection of the inclined plane? is hinged to the lower end portion of the primary section and cornprises the flooring 61 which is pivotally connected with the side bars 31 by means of secured to the lower and upper portions of the primary and auxiliary sections of the inclined plane and pivotally connected together, as shown in Figs. 3 and 4. This .flooring 61 is braced by the cross-bars 64 "which bars are connected by the truss-rod Guiding shoes 66 are secured to the lower end portion of the flooring 61 and are provided with downwardly curved points 67 which dig into the ground, as shown in F ig-.= 6, and: prevent the edge of the scoop fromeatchingv as the scoop starts up "the inclined planer This scoop 68 isofthe usual type used in excavating and is provided with the forward and rear yokes 69 and 70 which yokes are pivotally connected with therear andforward end portions of the scoop so that the scoop may be connected withthe' ends-ofthe line 71. This line 71 passes around a. pulley wheel- 72' carried by a stake 73 and after passing. over the pulley wheels52 passes-around the'dru'm 74 of the engine. 1

VVhenthis deviceis to be transported to the place where it is to be used, the engine is removed from-the cradle and the auxiliary section of the inclined plane is folded as shown in Fig. 2. The forward and rear trucks are connected by the coupling shaft 75 at which time the device may be moved to any desired position. When the machine reaches a place where it is to be used, the coupling 75 isremoved and after the cradle has been lowered to the dotted line position shown at Fig.- 5 ,-theengine is then putin place and the cradle raised to the elevated position. The auxiliary section of the inclined plane is then lowered to the position shown in Fig. 1 with the points of the shoes digging into the groundgand the line 71 is then passed overthe pulley wheels 52,- and after one end portion has been passed around the pulley wheel 72 carried by the stake -78 the'ends of the lines are connected with the yokes 69 and 7 0.

The excavator is now ready for operation, and when the engine is started, the scoop will be draggedalong' the ground toward the inclined planer As the scoop passes along the groundit-is tilted sothat the dirt will be scooped up-into the scoop until the auxiliary section of the scoop rests onthe inclined plane; When the forward edges of the scoop strike the guiding shoes 66; the scoop will -be'caused to ride on to the inclined plane, and wilh thentravel on this plane until it reaches the upper plat-form- As soon as the scoop reaches the upper platthe upper platform. Whenthe tilting platform tilts, the hopper built around the opening formed in the upper platform prevents the dirt from being thrown from the scoop upon the upper platform. It will thus be seen that the dirt will not gather upon this upper platform and make it necessary for a workman to climb onto the platform and shovelthe dirt from the platform in the opening into the wagon. As soon as the scoop is emptied, the engine is started to rotate the drum in the opposite direction fromv that in which it rotated when bringing the scoop up the inclined plane, and this will cause the scoop to be carried down the inclined plane to the bottom where it can be again filled with dirt. As soon as the scoop leaves the tilting platform, this platform will return to its normal position, shown in full lines in Fig. 5 c
