This invention relates to an improved snow shovel and digger, and has for an object to provide a construction whlch may be used for'shoveling' snow or used 1n dig- 6 ging earth, the arrangement being such that the snow or earth is lifted and discharged into a waiting conveyance.

Another ob ect of the invention is to pro vide' an apparatus which will dig into; a

bank through the power of the engine driving the apparatus and then lift the digging member for causing a part of the material to be discharged at a given point.

Another object ofthe invention is to pro- 1 vide a shovel and digger whereinthe shovel may be adjusted longitudinally without preventing its swinging movement as it moves from a digging position to a discharge POSI- tion.

A still further object of the invention is to provide an apparatus which may be used to shovel snow or dig earth or other material, the arrangement being such that the parts may be readily converted so as to be used in either way, and additionally converted to present a torch structure for melting snow or ice.

Figure 13 is a fragmentary rear view of the cutting roller shown in Figure 1 the same disclosing certain features of the in vention.

In constructing an apparatus disclosing 7 the invention, it is aimed, among other things, to provide a strong and very simple structure wherein the parts may be adjusted for causing the shovel to take up snow, ele-' vate the same a certain distance and discharge the snow into a wagon at one side of the apparatus. In addition, it is aimed means for dig:

to prov de means which may be associated with the shovel, whereby the shovelmay readily remove earth and discharge the same in the same manner as it discharges snow. In addition to these two features, an additional attachment may be provided and'associated with the shovel, whereby snow or ice may be melted and allowed. to run away as water instead of bodily removed.

The accompanying drawings show a construction for accomplishing these different .results, wherein "1 indicates a frame of any desired kind formed with suitable platforms, braces and the like and supported by suitable traction wheels 2. The front traction wheels 2' are driven by suitable mechanism through the shaft 3. The shaft 3 is provided with a clutch member 4 'co-acting with a clutch member 5 splined on the shaft 6 which is. rotated by the engine 7. The engine 7 may be of any desired kind, as, for instance, an ordinary internal combustion engine. The engine 7 is supplied with the usual reversing mechanism 8, wherebly shaft6 may be driven in either direction. gear Wheel 9 is loosely mounted on shaft 6 "and carries a clutch member IOco-acting with clutch 5 so that when the clutch 5 is interlocked with the clutch member 10, sprocket wheel 9 will rotate and will drive the sprocket chain 11, which in turn will drive the sprocket wheel 12. The sprocket wheel 12 is rigidly secured to a shaft 13 carrying a pinion 14 mm continually meshing with the bevel gear 15.

Gear 15 isrigidly secured to a drum 16,

which drum is adapted to wind the rope or cable 17. A brake drum 18 'is rigidly connected with the drum 16 and co-acts with- 1 through suitable levers, links and the like to a hand controlled lever 21, whereby the clutch member 5 may be moved into engagement with clutch 4 or clutch so as to rotate the drum 16 or shaft 3 as preferred.

Cable 17 extends over a pulley 22 carried by part of the frame 1. Y From pulley 22 cable 17 extends downwardly and is connected at 23 to a shovel guide 24, said shovel guide being preferably rectangular and pivotally mounted at 25 on part of the frame 1. The shovel 26 is provided with a rectangular section 27 and an excavating section 28 Section 27 is provided with spaced projections or enlargements 29, between any of which a set screw 30 may be forced for locking the shovel 26 in different-adjusted positions in respect to the guide 24. A rest or brace 31 is secured in any desired manner to the frame v1 and acts to preventthe rearward swinging movement of the shovel 26 beyond a certain point and also vpermits pressure to be brought on the shovel to force the shovel into snow, earth or some other substance. In case it should be desired to have the excavating section 28 operate at a higher point than that shown in Figure 1, the screw member 32 is moved in the proper direction for causing the abutment 33 to gradually swing the shovel upwardly. When the device is in operation, the engine 7 is', of course operating and the control lever 21 is shifted to cause clutch 5 to engage clutch 4. This will cause the rotation of the traction wheels and move the apparatus until the excavating section 28 has excavated or been inserted into a supply of snow or other material 34. When, the right amount of snow has been secured, lever 21 is shifted so that clutch 5 will be disengaged from clutch 4 and will be moved almost immediatel over into engagement with clutch 10. Thls will a stop the forward movement of the apparatus and will immediately cause a rotation of drum 16 for winding cable 17. Upon the winding of cable 17, the guide 24 and the shovel 2-6 and associated parts will be immediately swung upwardly to, for instance, the position shown in Figure 5. As the .shovel moves to substantially this position,

the snow or other material will slide under the action of gravity downwardly and be discharged out the inner end of guide 24 so as to be received by the chute 35. This chute, as shown in Figure 2, is provided under either 0 with a tilting blade 36 which acts as a shifting device or switch for causing the snow to be dischar ed out the auxiliary chutes 3'? or 38. Wfi a Wagon or rece tacle of some kind is placed f the chutes 37 01" 38, and as the snow is discharged the wagon or other container will receive the same. In case it is desired to discharge the excavated material at a higher point, the same is caused to passout the, auxiliary chutes 39 or 40. This is done by using the modified structure shown in Figures 5 and 6. This modified structure consists of an end member 41 adapted to be bolted to the guide 24, and a deflecting member 42 which is tremovably positioned in the inner end of the guide 24. The deflecting member 42 is held in place by a hook and e e structure 43, and at one end is supporte by a bracket 44. When discharging out the other auxiliary chute, the plate 45 is shifted to the opposite side.

The deflecting member 42 must, of course, be-

the crank being held in veither of its positions by a suitable pin 48. At the rear of the apparatus, there is rovided a number of cuting disks-49 rigi ly secured to the shaft 50 which is rotatably mounted and which is carried by springs 51, which springs have one end connected with the frame 1 while the opposite end is normally supported by a cable 52 held in a given position by a drum 53. The drum 53 is locked in any desired position by any suitable means, as, for instance, a pawl and ratchet, and is rotated manually by a suitable crank 54. When it is desired to cut the snow or ice or to cut the earth, the. disks 49 are lowered to the' dotted position shown in en the apparatus 'IS in use,

Figure 1 and the apparatus moved over the preferably an excavating head is provided,

as shown in Figures 9 and 10, said head consisting of a number of excavating teeth 56 and a number of stirring blades 57. These are bolted or riveted in place at the forward end: of the excavating section 28 of shovel 26. Where the ground needs to be loosened up,the apparatus is moved 'back wardly so that the blades 57 may be pulled through the earth and loosen the same. After this, has been done, the apparatus is mshovel the melted orproperly burn phalt and move the same again moved forwardly. and the teeth 56 will further loosen up the earth and help guide the same onto the excavating sect1on28, from which it is moved by gravity in a' similar manner to the'way the snow is caused to be moved. In order to prevent an upward swingin of the shovel 26 when the blades 57 are unctioning, a hook 58 is used, said hook fitting over a pin 59. A cable. 60 extends from hook 59 to an operators position near engine 7, whereby the operator may at the proper time raise hook 58 so as to permit the shovel" to be swung upwardly in substantially the position shown in Figure 5. l

Under some circumstances, it might be desired to melt the snow or ice, and when this is the case suitable bars 61 are connected by bolts or otherwise to the excavating section 28 of shovel 26. The bars 61 are adapted to receive the respective hooks 62 which are rigidly secured a burner 63, said burner being supplied w h gasoline or other combustible matter. This burner may be of any desired kind but preferably one that will cover a comparatively large surface and one wherein the flames will be projected downwardly in order to secure the best melting action. I I a It will be noted that the burner may be used not only to melt snow and ice, but ma be used to melt asphalt or other materia and in the case of melting of asphalt the device may be readily used to pick up. b the asto a truck for dis osal.
