tain new and useful In'uarovements in Coaltion.
Cars, of which the following is a specifica- This invention relates to certain new and useful improvements in coal cars and has particular reference to that type of car employed in the art of mmlng for the haullng of the coal from the mine pit to an elevator shaft or other outletof amine.
A further object of the invention resides in the provision of a pit coal car having the bottom thereof formed of parallel rack bars between which, teeth of a raker frame project for agitating the coal when placed in the car to sift the coal dust and dirt from the coal preparatory to transferring the same to the exterior of the mine.
1th the above and other objects in view, the present invention consists in the novel form, combination and arrangement of parts hereinafter more fully described and shown in the accompanying drawings, wherein like reference characters indicate similar parts through out the several views.
In the drawings,
Figure 1 is a side elevational view of a coal car constructed in accordance with the present invention, the same being partly shown in section to illustrate the raker frame beneath the car,
Fig. 2 is a vertical cross sectionalview taken on line II-II of Fig. 1,
Fig. 3 is a fragmentary end elevational view of the car,
Fig. dis a horizontal sectional view taken on line IV-IV of Fig. 1 showing the rack bottom of the car,
Fig. 5 is la detail sectional view of a portion of the car showing the. wheel bearing and the block for supporting the sliding raker bar frame,
Fig. 6 is a cross sectional view taken on line VI-VI of Fig. 5, and
Fig. 7 is a fragmentary plan view showing the axle bearing for the car and the sliding raker tooth frame.
Referring more in detail to the accompanying drawings, there is illustrated a mine pit car adapted for hauling coal in a mine and embodying a frame structure including side walls 1 that slope at their lower ends in the usual manner to provide substantially a. hopper construction with end walls 2 that are connected to the bottom frame 3 by exterior brace bars 1, one end wall 2 being secured in place by the link arms 5 pivoted as at 6 to the upper edges of the sides 1 to enable said end wall 2 to be moved upwardly by the pivotal movement of the links wheneverrdesired. For
purposes of coupling the cars in series, the
The wheel mounting for the car includes the provision of bearing blocks 9 at opposite sides of the car frame and through which the axles 10 are journaled, while supporting track wheels 11 i are mounted upon the outer ends of the axles 10 and maintained spaced from the blocks 9 by the bearing members 1.2.
As shown in Figs. 2 and 5, the bottom 3 of the car is cut away within the side and end walls thereof and a rack frame inserted therein, said frame being formed of a plurality of spaced longitudinal bars 13, the extreme opposite bars 18 of which rest upon the adjacent side edges of the bottom at the cut away portion thereof, the bottom 3 of the car being supported on the bearing blocks 9. In the loading of coal into the car, dust, dirt and otherforeign matter is placed therein with. the coal and the major portion of such coal dust, etc, will fall between the rack bars 13, and in order to eliminate all of such dirt, a raker frame is slidably positioned beneath the rack frame and is provided with teeth that project upwardly through the rack frame bars for agitating the coal therein. The raker frame is of rectangularformation embodying side bars 14:, transverse end and intermediate bars 15 and end projecting angular handles 16 as shown in Figs. 1 and 3. The inner upper corners of the axle bearing blocks 9 are cut away to provide ledges 17 upon which the side bars of the raker frame are slidably mounted as clearly shown in Figs. 5 and 7, upstanding teeth 18 beingcarried by the transverse bars 15 for projecting upwardly between the longitudinal rack bars 13. The reciprocable movement of the raker frame is limited by the raker teeth 18 engaging the transverse end bars 19 of the rack bar frame as shown in Figs. 1 and 4.
believed that the construction and operation will at once be apparent, it being noted that the reciprocation of the raker frame 14 will move the teeth 18 between the rack bars 13 to remove therefrom coal dust, dirt and other foreign matter so that the lower bed of coal in the car will leave the mine in a substantially clean condition.
While there is herein shown and described the preferred embodiment of the inventiom it 'is nevertheless 'to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as hereinafter claimed.
What is claimed as new is:
1. A coal car comprising a body frame, bearing blocks for supporting the frame, axles journaled in said blocks, track wheels on said axles, a rack bar frame constituting the bottom Wallof the car and supported on said body frame, shoulders formed on said blocks; a raker frame slidably mounted on the shoulders of said bearing blocks and having teeth extending upwardly between the rack bars to be reciprocated therein, and operating handles projecting from one end of the raker frame to effect reciprocation of the raker frame.
2. A coal car comprising a body frame, bearing blocks for supporting the frame, axles journaled in said blocks, track wheels on said axles, the bottom of the body frame being formed of longitudinal rack bars, the opposite inner faces of the bearing blocks being formed with guide shoulders, a raker frame slidably mounted on the shoulders of the bearing blocks and guided thereby, upwardly extending teeth carried by the raker frame projecting between the bars of the frame bottom, and means for reciprocating the raker frame on the shoulders of the blocks.
In testimony whereof I affix my signature.
GEORGE KUSHNER.
