To all whom z'tmay concerns Be. it knownthat I, TIN (J NTQG- iXN-DER- soN, a citizen of the, United .StatesofAmerica, and resident of-Thief RiverFall'giIienquire moving ahead from. time totiine' during the operation thereof. .7

Generally stated, the object. of my invention is to provide an improved apparatus of this kind having means .for raising the ein cavator or other .heavystructure, 'and'fin- \vhich the further operationof thelifting means,,.after the weight ofztheexcavator. or other structure has. been temporar ly transferred fromits ownrunway's. or othersup porting means to a traveling support, 1 will then shift the excavator or. other structure forward. I

It is also an object toprovidecertain details and features of. construction and I combinationstencling to increase the gen ral shown inFi-g. 1.

efliciency and desirability ofa propelling ap paratus' of this particular; character.

To the foregoing and other useful ends,

my invention consists in matters hereinafter set forth and claimed.

In the accompanyingdrawings Figure 1 is a plan -of an..excavator body provided with a propelling apparatus embodyingthe principles ofmyinvention. Fig. 2 is aside elevation of the structure Fig. 3 is a transverse section on line 3-8 Fig. 4 is an enlargedside elevation of a portion oftsaid-apparatus. ,p o

Fig. 5 is a plan of the device shown in Fig. :4;

As thus illustrated, the excavator body A may be .iof anyvsuitable, known or aprproved character, and is provided with-sup.

porting runners or shoes a, at the four corners thereof, wherebyit is adapted to rest on the ground during the excavating op- 'eration. It will be understood that the eX- cavating apparatus (not shown) can be of any suitable character.

Between the side beams l and 2, at each Side. of the body A, a supporting n me-n is disposed upright and provided Witlr-as'hoe- Z) which rests onthe surface of ground; A smallframe or cage 61S also provided at each side of the excavator body, in position to embrace the inclined upright 3 of the frame B, and isfprovided' with" rollers 4!; 5,6

and 7.to engage thebody frame A, in a manner that will be readily understood. Each frame Chas a small; triangular element X which is pivotedon the axis ,of-the rollers 7 and which is provided'with rollers, w to bear against the front side of theup.'

rollerst and 5 are on the axeszof. the sheaves 11 andlO, respectively, willfbe seen, and support the carrier C on the body, which permits freedomof motion and prevents binding of the relatively movable parts. The ca'ble D has its opposite ends secured at 12'to the-frames or cages C, and then extends upwarduover the sheaves 9, downward around the sheaves 10, upward and over the sheaves, 8, and thenrdownward. and under the sheavesjll', thus forming a powerful lifting apparatus. The said cable extends around, the sheaves 13 andi l f on e the rear endof the. excavator bo'dy A, a ndj the middle portion. of this cable extendsfaround'the pulley E, which latter is connected WithQthe pulley F around. which travels "the cable 7 of the winding idrum G, therother endof this cable fibeing attached to the eXCavator body at .15,"whjer eby the operation-of; said drum in the direction to wind up the cable f causes a, tigl.lt ningc of th able D. and a Q neaaeea to the shoes I) of the supports B, and a continued operation of the cable D exerts a forward pull on' the rear end of the excavator body-frame A, causing it to shift forward on the rollers 6 and 7, in a manner that will be readily understood. Then the bodyframe A is lowered to the ground. I

The means for pulling the frames B forward is as follows: The cable H has its opposite ends attached at h to the bases of the frames B, and said cable travels around the sheaves 16, 17 and 18 on the front end of the body-frame A, the middle portion of this cable being attached at 19 to the shank of the pulley 20, which latter engages the cable I which has one end portion wound on the drum 6 and its other end attached at 21 to the excavator body-frame. With this arrangement, and by operating the drum 2' after the excavator body-frame is lowered to the ground, the cable H will be tightened to pull the frames 1% forward on the ground. During this operation, the frames or cages C slide forward on the sides of the excavator body-frame. After this is done, the lifting apparatus is again ready for operation, so that the body-frame A. can be given another movement forward. Thus the frame A. and the frames B take turns, so to speak, in moving forward, the frame A moving forward while the weight is, on the frames B, and the said frames B being shifted forward when the weight is on the frame A, thus accomplishing the desired movement forward from time to time during the excavating operation.

I do not limit myself to the exact construc tion shown and described.

' What I claim as my invention is:

1. In a propelling apparatus for intermittently shifting a heavy body along the ground, a frame adapted to rest on the ground, a carrier movable up and down on said frame, rollers on said carrier to support said body, sheaves on said carrier, sheaves on said frame, a cable engaging all of said sheaves, means to secure one end of said cable to the front portion of said carrier, so that a pull on said cable will raise said carrier, and means on said body to operate said cable and thereby pull the body forward on said carrier.

2. The said structure, as specified by claim 1, having rollers tov support the carrier on said body, in which means are provided for permitting said carrier to tilt with the body without causing the cable to bind on said frame.

3. The said structure,-as specified in claim 1, having rollersto support the carrier on said body, in which said frame is inclined forward, and in which said cable has the 'upright portions thereof also inclined for ward. v 7

4. The said structure, as specified in claim 1, in which the front end of said carrier has a pivoted element to engage said frame.

5. In a propelling apparatus for intermittently shifting a heavy body along the ground, a frame adapted to rest on the ground, a carrier movable up and down on said frame, rollers on said carrier to support said body, sheaves on said carrier, sheaves on said frame, a cable engaging all of-said sheaves, so that a pull on said cable will raise said carrier, means on said body to operate said cable and thereby pull the body forward on said carrier, and means for permitting said carrier to tilt with the body without causing the cable to bind on said frame.

6. In a propelling apparatus for intermittently shifting a heavy body along the ground, a frame adapted to rest on the ground, a carrier movable up and down on said frame, rollers on said carrier to support said body, sheaves on said carrier, rollers on the axes of said sheaves to support the carrier on said body, sheaves on said frame, a cable engaging all of said sheaves, so that a pull on said cable will raise said carrier, and means on said body to operate said cable and thereby pull the body forward on said carrier, said frame being inclined, forward, and said cable having the upright portions thereof also inclined forward.

.7. In a propelling apparatus for intermittently shifting a heavy body along the ground, a frame adapted to rest on the ground, a carrier movable up and down on said frame, rollers on said carrier to support said body, sheaves on said carrier, sheaves on said frame, a cable engaging all of said sheaves, so that a pull on said cable will raise said carrier, and means on said body to operate said cable and thereby pull the body forward on said carrier, the front end of said carrier having a pivoted element to engage said frame.
