To all whom it may concern:
Be it known that 1, JOHN MOGIRR, a citizen of the United States, residing at De Kalb, in the county of Dekalb and State of Illinois, have invented a new and useful Excavator and Loader, of which the following is a s )GCifiCHtlOD.
l he invention relates to an excavating and wagon loading machine.
The object of the present invention is to provide a simple, practical and comparatively inexpensive excavating machine of strong and durable construction and maximum capacity, adapted for excavating eel lars, making cuts and fills in railroad constructions, digging ditches, and the like, and capable of elevating the excavated material and of loading the same on wagons and other vehicles. A further object of the invention is to provide a machine of this character adapted for loading various kinds of materials, and equipped with means adapted to scoop or excavate directly in front of the machine and also at a distance to either side of the same, whereby the machine without changing its position is adapted to excavate a relatively large area. Another object of the invention is to provide a gravity acting unloading device adapted to be dropped into position for engaging the contents of a bucket, and capable through the return movement of the bucket of automatically unloading the same and of discharging the contents of the bucket onto an elevating and loading conveyer.
lVith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, with in the scope of the claims, nay be resorted to without departing from the spirit or sacrilicing any of the advantages of themventi on In the drawings 2 Figure 1 is a side elevation of an excavating and loading machine, constructed in accordance with this invention.

Fig. 2 is a front elevation of the same.
Fig. 3 is a plan view.
rt is a central longitudinal. sectional view.
Like numerals of reference designate corresponding parts in all the figures of the drawings.
' In the accompanying drawings in which is illustrated the preferred embodiment of the invention, the machine comprises in its crmstruction a main frame or supporting framework 1, mounted on front and rear wheels 2 and to enable it to be conveniently transported from one place to another. The main frame or framework is designed to be constructed of any suitable material, and in the accompanying illustration it is composed of horizontal side sills 4: connected by suitable transverse beams 5 and having mounted upon them front and rear uprights 6 and 7, which support the upper ends of oppositely inclined frame pieces or members 8 and 9. The inclined members 9, which are located at opposite sides of the frame, extend upwardly and rearwardly from the front ends of the sills to the upper portions of the rear upright 7, and they also project in advance of the sills, extending downwardly and forwardly, as clearly illustrated in Fig. 1; of the draw ings. The said inclined frame pieces or members 9 are supported between their ends by intermediate vertical posts or uprights 10 and 11, arranged in pairs at opposite sides of the frame and mounted upon the side sills at the ends of the transverse beams 5. The oppositely inclined frame pieces or members 8 have their lower ends mounted.
upon and suitably secured to the inclined frame pieces 9 at a point intermediate of the ends thereof, and they extend upwardly and forwardly from the said inclined frame pieces 9 to the upper ends of the front uprights 6, being preferably connected at their upper terminals by a cross piece 12. The upper ends of the rear uprights 7 are connected by a cross piece 13, and the sides of the frame are also braced by longitudinal side pieces 14, extending from the front upright 6 to the inclined frame members 9. The frame, h r ma b ns r c ed n any other suitable manner to provide a supporting structure of the desired strength to adapt the machine to the character of work for which it may be designed.
The machine is equipped at the back of the main frame with a chute supporting frame 15, consisting of an elevated platform 16 supported at its inner portion by the rear uprights 7 of the main frame and at its outer portion by uprights 17, located a suflicient distance from the main frame to provide a passageway for vehicles. The chute supporting frame is designed in practice to be secured to the main frame by any suitable means, so that it may be removed therefrom when the machine is to be transferred to another place. The platform, which has its inner end supported upon a cross piece 18 of the mainframe, is located at a sufficient elevation to enable a wagon 19, or other vehicle to be run beneath a chute 20 mounted upon the platform and an opening 21 thereof and extending upwardly at an inclination to a point beneath an inclined endless conveyer.
The inclined endless conveyer, which is disposed longitudinally of the machine centrally thereof, extends upwardly and rearwardly from the front terminal portions of the inclined frame piece 9 to a point above the chute, and it comprises an endless belt or apron 22 supported at intervals by transverse slats 23, which are suitably secured at their terminals to sprocket chains 24, located at opposite sides of the conveyer and arranged on upper and lower sprocket wheels 25 and 26. The sprocket wheels are arranged at the ends of upper and lower rolls 27 and 28, preferably mounted on shafts 29 and 30, which are journaled in suitable bearings of the main frame. The upper and lower sprocket wheels are suitably fixed to the shafts 29 and 30, and the lower shaft 30 is preferably carried in adjustable bearings 31, slidably mounted in suitable guides 32 and adapted to be adjusted by screws 33 for maintaining the sprocket chains at the desired tension. The endless belt or apron, which is constructed of suitable flexible material, is looped between the transverse slats to provide flexible pockets 34, adapted to receive material from a central bucket 35. The material, which may be excavated earth, manure, or any other material, which it is desired to load, is discharged onto the lower front portion of the endless conveyer and falls into the pockets 34 and is carried upward by the same to a point above the chute 20. The pockets in passing around the upper roll discharge their contents into the chute and the material is directed by the same into the wagon 19, or other vehicle or receptacle,
The central bucket 35, which may be constructed of any suitable material, is prefi erably of the scraping or excavating type and is composed of a straight flat bottom 36, spaced parallel side walls and a curved rear wall 37', which is preferably formed integral with and constitutes a continuation of the bottom 36. Any other preferred form of bucket may, of course, be employed, and it is equipped'at the back with projecting han dles 38, adapted to enable the bucket to be held in position for causing the same to dig into the ground, or into the material to be loaded. The main frame is equipped at the front with an inclined guide or skid 39, extending upwardly and rearwardly from the ground to a point above the lower portion of the endless conveyor and provided above the same with an opening lO through which the material falls when it is discharged. from the bucket. The conveyer extends substantially across the space between the sides of the frame, and the front terminals of the inclined frame pieces or members 9 are connected by a transverse wall ll, located above the front end of the conveyer and adapted to cooperate with the lower portions of the said frame members or pieces 9 to form a partial hopper forretaiir ing the material on the conveyer until it is carried upward in the pockets 81. The inclined guide or skid may be constructed of any suitable material and in practice it is designed to be removably mounted on the front projecting portion of the main frame and is adapted to be removed therefrom when the machine is to be moved.
The bucket is provided at its front with a pivoted bail 4-2 to which is connected a draft cable 13, wound around and extending from a central horizontally disposed drum 41:4 and adapted to be operated to draw the'bucket from the point where it is filled to the machine and onto the same. The bucket is drawn up the inclined guide or skid until it occupies a position over the opening 40, which is of a width slightly less than the guide or skid, supporting portions for the bucket being arranged at opposite sides of the discharge opening 40. The bucket is returned to the point of excavation by means of a cable 45, secured at one end to the rear portion of the bucket at 16 and extending around a guide pulley 47 and having its other end portion attached to and wound around a horizontal drum 49. The guide pulley or sheave 47 is mounted in a suitable supporting frame 50, which is anchored the proper distance in advance of the machine, the central bucket 35 being adapted to travel back and forth to and from the machine.
The contents of the bucket are removed by means of an unloading device 51, preferably composed of spaced sides 52, pivoted at their inner ends at 53 to the outer side faces of the f o t up g t 6 a d connec d at their outer ends by a transverse rod or portion 54, which is provided with a series of depending curved fingers or tines 55, adapted to extend downwardly into the bucket adjacent to the curved rear wall thereof. In practice the unloading device will be sufliciently heavy to be gravity acting, so that when it is permitted to descend, it will enter the bucket and penetrate the material. The unloading device is connected with the hoisting cable 56 suitably connected at its lower or outer end to the transverse bar or portion of the unloading device and extending upwardly therefrom to a drum 57, adapted to elevate the unloading device and maintain the same in an elevated position until the bucket has been drawn upwardly over the discharge opening 40. As soon as the bucket is in position, the drum is op erated to permit the unloading device to drop by gravity into the bucket, and when the latter is moved downwardly and outwardly by the return cable, its contents are automatically raked from it by the unloading device, which remains in a relatively fixed position.
The central bucket is adapted to excavate and operate on the material to be loaded at points directly in front of the machine, and in order to enable the latter to excavate and otherwise operate at opposite sides of it, the machine is equipped with vertical side drums 58 having cables 59, each of which extends forwardly in a direction longitudinally of the ma chine to a suitable guide pulley and then transversely of the machine across the front thereof to the opposite side of the same, as clearly illustrated in Fig. 2 of the drawings. Each cable 59 is equipped with a side bucket 61, constructed similar to the central bucket and adapted to excavate and carry the excavated earth or other material from a point laterally of the machine to a point directly in front of the same, in order that such material may then be carried to the conveyer by the central bucket in the manner before described. The paths of travel of the central and side buckets intersect, and the pulleys or sheaves 60 are suitably mounted on stakes or posts 62, which are designed to be driven into the ground at the proper point in advance of the vertical side drums, but the side cables may be guided in any other suitable manner, and the transverse portions may be arranged at any angle to the longitudinally disposed portions and they enable the machine to excavate relatively large areas at each side of it. Any suitable means may be employed for returning the side shovels to the points of excavation. The vertical drums are mounted upon shafts 63, journaled in suitable bearings of lateral extensions or wings 64 of the main frame. The lateral extensions or wings are preferably composed of upper and lower horizontal El of:
beams connected at their outer ends by vertical pieces and secured at their inner ends to the sides of the main frame, but they may, of course, be of any other preferred construction and may be braced in any suitable manner to secure the requisite strength.
The machine may be equipped with a suitable engine or motor, but in the accompanying drawings provision is made for operating the machine from an independent source of power.- For this purpose the pulleys 65 and 66 are mounted on a relatively short longitudinal shaft 67, which is journaled in suitable bearings of the main frame at one side of the machine. The pulleys 65 and 66 are adapted to receive a belt 68, as illus trated in dotted lines in Fig. 3 of the drawings, for connecting it to a suitable engine or motor. The pulleys 65 and 66, which are rigid with each other, are loose on the shaft and are designed to be coupled to the same by a suitable clutch 69, having an operating lever 70. As any preferred form of clutch may be employed, a detail description of the several clutches of the machine is deemed unnecessary. The longitudinal shaft 67 is provided at its rear end with a beveled pinion 71, which meshes with a beveled gear wheel 72, mounted on a transverse shaft 7 3, and th latter carries a spur pinion 74, which meshes with alarge spur gear wheel 7 5 keyed or otherwise fixed to a countershaft 76 from which the conveyer and the various drums of the machine receive their motion. The shaft 29 of the upper roll 27 of the conveyer has an extended end portion 77, which is connected by sprocket gearing 78 with the transverse shaft at one end thereof. This gearing transmits motion from the countershaft to the endless conveyer, which operates continuously while the driving pulleys 65 and 66 are clutched to the longitudinal shaft. The shaft 79 of the central horizontal drum 44 is connected by sprocket gearing 80 with the countershaft 7 6, a suitable clutch 81 being provided at the shaft 79 for connecting the sprocket gearing with and disconnecting it from the shaft 79. The operating lever 82 of the clutch 81 extends clownwardly to a point within easy reach of the operator when standing upon the ground at the side of the machine. The clutch 81 is thrown into operation for winding up the draft cable to draw the central bucket into the machine, and it is thrown out of operation to permit the draft cable to unwind freely when the drum 49 of the return cable 45 is rotated to carry the bucket back to the point of excavation or to other material to be loaded. The shaft 48 of the drum 49 is connected by sprocket gearing 83 with the transverse shaft 76. The sprocket gearing 83 is located at the opposite side of the machine from that at which the sprocket gearing 80 located, and it has a suitable clutch,
Si operated by a lever 85, extending to a point within easy reach from the ground.
The shaft 86 of the hoisting drum 5'? of the unloading device is connected with the countershaft 7Gby sprocket gearing S7 having a clutch 88 operated by a lever 89. The shafts 63 of the vertical drums are provided at their upper ends with horizontal beveled gear wheels 90, which mesh with beveled piuions 91. of transverse shafts 92, jour-- naled in suitable bearings at the tops of the laterally extending wings or supports (3t and connected with the countershaft 76 by sprocket gearing 93, located at opposite sides of the machine and provided with clutches 94, which have operating levers 95 adapted to throw the vertical side drums into and out of operation. The central and side buckets may b operated independently or sinmltaneously by means of the several clutches, which are adapted to connect the drums of the various cables with and disconnect them from the continumisly rotating countershaft. By this construction and operation, excavations may be rapidly made and the excavated material may be easily and quickly loaded.
