Upon the engine shaft 9 is fixed a worm 15, which meshes with the gear 16, ori the drum shaft 17 A clutch 18 is provided kfor communicating the` rotation of the gear 16 to the shaft 17. A brake 19, on the shaft 17, having connections with the hand Ilever 20, serves to control the respective cable drums l21 and 22. Pivoted at the respective points 23 and 24 on the frame '1, are the pivotal arms 25 and 26, having pivotal connection at the points 27 and 28, with the shoveling bucket 29. The shovelingbucket 29 is provided with an edged nose-piece 30, riveted to the body of the bucket 29. In the lower part of the rear of the bucket 29 are rollers 31, 31. Fixed to each end of the bucket 29, is a pawl catch 32. Pivoted to each of the arms 25 and 26 at the points 33, 33', are paWls34, 34. Each pawl 34 has an upstanding .arm 35 from which leads a line 36; that which has connection with the side arm 25, passes through a hole at 23, and that which has connection with the arm 26 passes through a hole at 24. Both lines 36, 36 have connection with a suitable controlling and operating device or lever, not here shown. Each of the arms and 26, has a fixed pin 37, upon which 1s journaled a pulley 38. A frame 39 standmg on and fixed to the frame 1,.has a braced part on each side, adjacent one of the arms 25, 26, and has pivoted thereon, a pulley 40. A post 41 projects outward from each s1de of the frame 39, and is positioned to engage the arm 35 of each pawl 34. Fixed to each post 41, is a cable 42, whichpasses down and around the pulley 38, and up and around the idler pulley 40, and down and around the respective cable drums 21 and 22. In order to protect the pivotal ends of the arms 25 and 26, there is provided a'guard shoulder A on each Side of the frame 1.

Referring now to Figs. 6, 7, 8 and 9, there is shown attached to the frame 1a, the various parts of the motor truck, including the engine 2u, the steering wheel 4a, and the driving-wheels 5a and 6", and the engineshaft 9a, upon which are shown two worms 15a and 15b. The worm 15a meshes with the gear 16@l and the worm 15`D meshes with the gears 16". These worm gears 16a and 16b are journaled on the respective shafts 17i1 and 17", and are connected therewith by therespective clutches 18a and 18h. Brakes 19"L and 19b are provided on the respective shafts 17a and 17h. Fixed to the ends of the shaft 17a, are the cable drums 21a and 22, and fixed to the shaft 17b are the cable drums 21b and 22". Suitable connections between a group of levers 43 and the clutches 18a and 18h, and the brakes 19al and 19b are provided, but not here shown. Pivoted at the points 44 and 45 on the frame 1a, are the pivotal arms 46 and 47. To the outer end of each arm 46 and 47 is pivotally mounted an extension link 48, having a pawl catch 49 integral therewith, and positioned for engagement with the hook end 50 of the pawl 51. A tension spring'52 connects the'pawl 51 with the post 53 integral with the pivotal arm. The pawl 51 is 'pivoted on an extension 54, of the pivotal arm, and has an upstanding curved arm 55 adapted for engagement with the cam-block 56, shown in Figs. 6 Aand 9, resting against a 1ug57 on the frame of the machine. A cable 55c connects the arm 55 to each of the arms 46 and'47 through their respective center holes at 44 and v45 with suitable manually operated means, not here shown The cam-block 56, pivoted at 58 can be swung out of the way, to rest upon the top of the 'lug 57. Pivoted .at 5 9 to the outer end of each link-48 is a stop-piece 60, fixed to the shoveling bucket 61. The stoppiece 60 has a finger 62 adapted to contact the tooth 63, upon a partial rotation of the bucket 61. A linger 64 integral with thel stop-piece v60, limits the rotation of the bucket 61 in the opposite direction. The shoveling bucket 61 has a nose-piece 65, extending across the face thereof, and also has a cable guide 66 at each end of the bucket, against whichrests a cable 67; there being one cable for each end of the bucket 61. Each cable is fixed to the nose-piece 65. In the rear of the bucket61, are two rollers 68, 68, which su port'the lower rear end of the bucket 61. gournaled upon each of the arms 46 and 47 is a pulley 69. Pulleys 70 and 71 are journaled on each side of the upright frame-work 72. The cable 67 passes up around the pulley and down around the drum 22h. Attached to the lug 57, is a cable 73, whichA passes down around the l pulley 69 and up around the pulley 71, then down around the cable drum 22a. The cables 67 and 73 with their various pulleys and connections are duplicated on the opposite side of the machine, in connection with the arms 46.

Referring now to Figs. 10 and 11, which illustrate forms of .steering mechanism adapted for use in the motor vehicle, shown in the other figures, referring particularly to Fig. 10, there is shown positioned for pivotal connection, with the fragment of frame 123, .which is similar to the chassis frame shown in the previously mentioned figures, a forked member 124, having journaled therewith a wheel 125. In the upper end of the member 124 is fixed a yoke 126, having connected with each end thereof, rods 127 and 128, which are connected with a yoke 129, fixed to avertical steering shaft 130, passing down through a steering post 131, fixed by the clamp 132 to the frame 123. The upper end of the shaft 130 has fixed thereto, a handle 133, for turning the Ashaft 130 of the steering wheel 125.

Referring now to Fig. 11, upon the fragment of the frame 134. is shown positioned for journaling on said frame, the forked member 135, adapted to hold aA steering wheel such as 125 of Fig. 15. On the pin 1363, the frame 134, is pivoted a lever 136,

having integral therewith a segmental beveled rack 134, meshing with asegment 138 of a beveled gear mounted upon the pulley 139,v which is adapted for pivotal engagement with the frame 134. Fixed tothe `A member 135 is a pulley 140, -whichis 'connected With the pul1ey 139, by the vcable 141 which is fixed at mid points 142, 143,

to the respective pulleys 139 and 140.l

Considering now the construction and operationof the various embodiments of my invention illustrated inthe figures, referring first to the truck power shovelshown in Figs. '1, 2, 3,4 and 5, in operation, the

` and the shaft 17, the motor vehicle is moved forward to force the bucket'29,into the pile of loose material to be transferred.l The vehicle is lthen stopped and the clutch 18 is thrown in to rotate the shaft 17 and cause the drums 2l and 22. to wind up each of the cables 42, 42 simultaneously and raise the pivotal arms 29 ,and 30,l with the loaded bucket 29,- into a position, just below that shown by the dotted lines 26, 29a and 34a, representing the respective side arm 26, bucket 29 and pawl 34 in dumping position. The vehicle is then backed away from the pile of material to be removed, and taken to the site at whichthe material is to be dumped. The drums 21 and 22 are further caused to wind the cables 42, 42, Vraising lines in Fig. l, approaching which position,l the arm 35, of the pawl 34, rubbing on the an extended link to each of the pivotal arms,

the side arms 25 and 26, with the bucket 29, into the position illustrated by the dotted post 41, causes a movement of the pawl 34, to release the same from the pawlcatch 32, permitting the bucket 29, to drop down, seeking a position, having its center of gravity directly below` its pivotal connection 28, viti' the a-rms 25 and 26, thus dumping the oa y Considering the type of truck power shovel shown in Figs. 6, 7, 8 and 9, `using the operator has tliechoice of two' dumping positions for the bucket 61. The material is gathered in the manner explained for the type of truck power shovel shown in Figs.l l

1 to 5' inclusive. -When dumping at the position of the bucket marked 61", the upward movement of the arm 47, approaching' the position 47a, by means ofthe winding 'of the cable 73 on the drum 22", causes the .unlocking of the hook 50 of' thepawl 51,

bythe rubbing'of the arm'55, on the'pivotal cam-block 56, causing the arm 55 to takethe position 552 The finger 64a remains in contact with the link 48a as shown by 'heavy' broken lines. When it is desired to dump at the position 61", the cam-block 56 is previously thrown out of the path of the arm 55 on its pivot 58, to rest in the horizontal position 56", so as to retain the hook 50 in locking engagement with the pawlcatch 49, and maintain the link 48, extended in the position 48". To dump the bucket 61 into the position 61", the cable 67 is drawn ontothe drum 22" by throwingl in the clutch 18", while the engine 2a is running, and by means of the guide 66 and the anchorage of the cable 67, in the nose-piece '65, the bucket 61 is turned into the position 61" and with it the :finger 64, leaves the link 48 to takethenposition64". Thebucket 61 29, shown in Fig. 1, the buckets 61 and 29 must be manually turned to hookthe pawls upon .their respective pawl- catches 49 and 32, ready for the next shovelful.

In order'to' give the operator more freedom in manipulating the various vlevers, I provide a steering device for the truck, having a hand lever such as 133 or 136 of the respective Figs. 1()- and 11, requiring the use of only one hand. In operating the form shown in Fig. 10, any angular movement given to the lever 133 isr communicated through the shaft130, to which it is fixed and the yoke 129, to the connections 127 and 128, to the yoke .126, giving an angular movement to the wheel 125, journaled in the fork 124. In manipulating the form of steering device shown in Fig. 11, any angular movement given to the lever 136, pivoted upon the pin V136", causes a partial rotation of the pulley 139, through the meshing of the segmental beveled racks 137 and 138, and the angular moveinent of the pulley 139 is communicated to the pulley 140, and the fork 135, through the cable 141, fixed tothe pulley 139 at the point 142, and fixed to the pulley 140 at the point 143.

Either of these forms of steering device may be used in connection with the truck construction, including means for operating the shovel shown in the various figures. The lever form of steering device is indicated in Figs. 1 and 2.
