A still further object of the invention is tofprovide a device of this character mounted upon a suitable truck provided with means whereby the body of the device may be raised or lowered and whereby the body may be revolved in any direction in relation to the truck.

With the above and other objects in view, which will be more apparent as the description progresses, the invention resides in the novel construction and arrangement of parts hereinafter fully described and claimed.

In the accompanying drawings, there has been illustrated a simple and preferred embodiment of the improvement and in which,

Figure 1 is a side elevation of the device illustrating the same in its tilted position and having its open body communicating with a suitable receiving car. Fig. 2 is a central longitudinal sectional view of the device looking in an opposite direction to Fig. 1, parts being shown in elevation. Fig. 3 is a top plan view of the device.

Fig. 11 is a detail view partly in section of a portion of the truck illustrating its connection with the body of the device. Fig. 12 is a sectional view upon the line 12-12 of Fig. 1. Fig. 13 is a detail perspective view of a portion of the slide and a shovel pivoted thereto. Fig. 14 is a detail of the slide showing the shovel connected thereto, the shovel being shown partly in section.

In the accompanying drawings t-he numeral 1 designates a truck of any desired or particular construction. The truck 1 is pro vided with the usual wheels which are adapted to engage wit-h the rails 2 upon the siding of a railroad track and the truck has its forward end inclined or beveled as indicated by the numeral 3. The horizontal flat top 4 of the truck is provided with a suitable turn table 5 and centrally projecting from this turn table is a pair of spaced ears 6, between which is pivotally connected as at 7, a depending ear 8 provided upon device,V 22. The rear end of the body 9 is iff-2 the body 9 of the machine. The face 4 of the truck is also provided with a circular l track and this track is adapted'for the reception of a pair of spaced sliding members 11. These members 11 are each provided with a tubular portion 12 which normally extends beyond the face of the said truck 1. These tubular members 12 are each provided .with a preferably cylindrical headed member 13, which is provided with a cent-rally threaded opening and which is free to revolve within the said collar. This member 13 has its enlarged face provided with a plurality of openings 14 which are adapted for the reception of any suitable bar whereby the said member may be easily rotated and the threaded bore of this member is adapted for the reception of a threaded rod 15, pivotally connected as at 16 to the bottom of the body member 9. By this arrangement it will be noted that the body 9 may have its rear portion elevated so as to bring the said body to any desired angle in relation to the truck 1 and it will be further noted that by providing the truck with the turn table 5 the body 9 may be rotated to any desired position and may be retained in said position through the medium of suitable threaded elements 17 carried by the members 11 and adapted to contact with the track 10. The body 9 of the device, see Fig. 5, comprises a detachable bottom portion 18 having its longitudinal edge upturned as at 19, to provide supports for the side members 20. It is to be understood that the upturned portions or offsets 19, as well as the lower portions of the side members 2O are each provided with suitable alining openings adapted for the reception of suitable removable securing members 21.

It will be noted that the greatest strain is imparted to the bottom 18 and this portion of the body frequently becomes worn or mutilated and by constructing this element as a detachable member a new bottom may be readily substituted when necessary. The bottom 18 is adapted to extend a suitable distance beyond the sides 20 and the forward extending portion of the said bottom is arranged at a slight inclination so that it may be readily positioned between the rails 2 inv close proximity with the material to be gathered, while the opposite or back portion of the body 9 is of a curved formation, shown at 10 to provide a lin or chute whereby the coal or other material may be guided to a car or other receiving provided upon bothY of its sides with suitable upstanding standards 23, each of an approximately V-shaped formation so as to provide a pair of spaced legs whereby great strength will be imparted to the said standards. These standards 23 have their upper portions or apeXes provided with alining@ openings and these openings are adapted for the reception of a suitable shaft 2t which is received within a suitable bearing 25 provided upon a cylinder or steam chest 2G. This steam chest 26 is provided with suitable inlet and outlet ports 27 and 28 one of which is connected with a suitable boiler or other source of steam supply, which in this instance is not illustrated. The steam chest or cylinder 26 is provided upon its opnosite sides with longitudinally extend'; guide ways or members 29. The guide ways v29 are each adapted for the reception of a suitable slide member 30 and these members 30 are provided .with suitable bearings whereby the projecting ears 31 arranged upon the sides 32 of gathering shovels 33 are connected with the side guides. By reference to Figs. 1 and 2 of the drawings it will be noted that the shovel members 33' are of a curved or arcuate formation and it will be also noted that the slide members 30 are each provided with suitable blocks or members 34 which bear against one side of the ears 3l so as to prevent the rotary movement of the shovels in one direction.

Positioned within the steam cylinder 26 is a suitable piston provided with the usual piston rod and secured to the end of the piston rod as at 35 is a cross beam 3G. be noted that the guides 29 project a suitable distance beyond the front face of the cylinder 26 and the central groove of these projecting portions is provided with longitudinally extending slots 37, Fig. 1.. The cross beam 36 is adapted to extend through these slots and to have its opposite ends provided with grooved wheels 3S. The wheels 3S ride upon the track 39 supported in suitable bearings 40, 41 and 42 carried by the sides of the body. The stationary track 39 has its outer extremity curved upwardly as designated by the numeral 43 and the extremity of this curved portion is bent rearwardly as indicated by the numeral 44. Pivotally mounted upon the bearing 42 is a switch member 45. This switch member is of an approximately V-shaped construction and has its apex normally resting upon the permanent track 39, while its rear upwardly curved surface 49 is retained in spaced relation with the upwardly turned portion of the said track 39. The member 41 has its upper extremity provided with an arcuate slot 4G which is adapted for the reception of a headed member 47 carried by the said switch 45. The supporting member 42 is also provided at its upper portion with an elongated slot 48 and this slot is adapted for the reception of a similar headed portion 49 carA ried by a car or supporting beam for the said switch member. Positioned within this slot and adapted to bear upon the body of the headed member 49 is a helical spring 50 which normally forces the lower portion of the V-shaped switch toward the permanent track 39. The upturned portion 43 of the track 39 is supported by a suitable bail 51 also provided upon the supports 42. By reference to Fig. 3 of the drawings it will be noted that the tracks 39 and the switches 45 are positioned a suitable distance away from the sliding members 30 so as to allow a suflicient space for the gathering members or shovels 33 to work therebetween.

It will be noted by reference to Fig. 6 of the drawing that the forward shovel member has its lower face provided with a plurality of teeth 52 whereby the said shovel will be permitted to dig within the pile of coal or other material to be elevated to the car 22. In operating the device the cylinder 2G is swung downwardly from its pivot 24 and the slides 30 carrying the shovel members 33 are forced rearwardly against the cylinder within the guides 29. Then steam is applied within a cylinder to the rear of the piston carried therein the piston rod will force the guide members forward through the medium of the beam 36 and the grooved wheels 39 will travel upon the projecting portion of the permanent track 39 and from thence will mount the upwardly inclined Surface provided by the switch 45. l/Vhen the sliding members are thus elevated it will be noted that the shovels are also raised and that the steam cylinder will be also upwardly inclined upon its pivots 34. As the wheels 38 reach the extremity of the said switch member 45 the same will be guided downwardly upon the upwardly turned portion 43 of the permanent track 39 and the downwardly extending enlarged portion 47 of the V-shaped switch 45. As the wheels describe this downward motion it will be noted that the forward shovel member 33 will be forced within a pile of material to be gathered within the body of the device and when the wheels reach the horizontal portion of the track 39 the car of the piston within the cylinder is reversed so as to draw the slides 30 rearwardly within the guides and again lowering the slides and cylinder, thus allowing the intermediate shovel members to sweep the material previously gathered by the outermost shovel to the car 22. lt will be noted that the V-shaped switch 45 will readily yield as the wheels 3S engage the same while traveling upon the permanent track 39, and it will be further noted that by this construction a great amount of material. may be elevated to the car 22 in a comparatively short length of time.
