COAL-TIPPLE.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed January 18,1907. Serial No. 852,915.

To all whom it may concern:

Be it known that I, JAMns S. Paras, a resident of Monongahela, in the county of Washington and State of Pennsylvania, have invented certain new and useful Improvements in Coal-Tipples, of which the following is a specification.

Coal tipples now in general use are provided each with a holding bar which is pivoted to and depends from the rear end of the tilting platform and cooperates with a holding device on the tipple structure for controlling the upward movement of the platform, being operated either as a brake for causing the platform to move slowly, or for arresting its movement altogether. When the platform is tilted this bar is elevated through the car approach, and it is not infrequent for cars to move toward the platform when the latter is raised, bumping into and breaking the bar, as heretofore no means have been provided for protecting the bar from such a blow. In fact the danger of breaking bars is so great that it is a common practice to have a supply of bars in reserve for each tipple, in readiness to replace those which are broken.

One object of the present invention is to. provide for a cushioned movement or play of the bar in the direction of movement of an approaching car, so that it may not only withstand the blow of a car, but also stop its forward movement.

A further object of the invention is to provide for cushioning the shock incident to the sudden stopping of the car when it reaches its position on the tilting platform. Injury to the tipple, and particularly the operating portion of the mechanism, is thereby avoided. This feature of the invention is preferably embodied in cushioned or yielding bearings in which the tilting platform oscillates, thus cushioning the tilting mechanism in its entirety, This cushioning of the platform also cooperates in a measure with the bar-cushioning mechanism for yieldingly resisting the blow upon the latter of an approaching car.

Still a further object of the invention is to provide improved mechanism for operating the car-holding stops or horns.

In the accompanying drawings, Figure 1 is a side elevation, partially broken away, of a tipple constructed in accordance with the invention. Fig. 2 is a crosssectional view on line 2-2 of Fig. Fig. 3 is a view on a larger scale of the bar holding and cushioning mechanism, and Figs. 4 and 5 are detail views of portions of the latter. Fig. 6 is a detail view of one of the platform bearings. Fig. 7 is a top plan view of the tilting platform, and Fig. 8 is an inverted plan view of the same.

Referring to the drawings, 2 designates the outside longitudinal timbers of the tipple structure, upon which are mounted the bearing slideways 3 in which are slidable bearings 4 for trunnions 5 of the tilting platform 6. The bearings are held normally in the rear ends of the slideways by springs 7, the latter being confined each by a bolt 8 secured to the bearing and extending through one end of slideways 3 where it is provided with nut 8. By this means the tension of the springs may, if desired, be regulated. Connected to platform 6 are the usual cross-over rails 9.

A tongue 10 extends rearward from the center of the platform, and overhangs the tipple approach. Pivoted at 10 to this tongue is the depending curved bar or sword 11, formed on its opposite edges with the alternately arranged stops or holding points 12 which cooperate with a movable holding device. This portion of the apparatus, as here embodied, is in accordance with reissue Letters Patent No. 12,553, granted to me November 6th, 1906.

Bar 11 operates through a casing 14, here shown secured to intermediate timber 2 of the tipple frame. This casing is constructed with two horizontal passages or slideways-one above the other. A slide 15 is movable in the upper guideway, being formed with a passage 15 for bar 11. This slide is reciprocated against the pull of spring 16 for engaging it with first one and then another of bar stops 12 for intermittently and suddenly stopping the ascent of the bar, and thus jolting the tilting platform for the purpose of shaking the coal from the car, all as described in my Letters Patent above referred to. Slide 15 may be conveniently operated by link 17 connecting it to an arm 17 of rock shaft 18, the latter carrying the upright operating lever 18.

In the lowermost slideway of casing 14 is guide 19 having a vertical passage which in shape corresponds to the cross-section of bar 11, and as I prefer to form the bar with side ribs 11, the passage in the guide has corresponding offsets 19. One end of the guide is provided with a depending lug 20, and a heavy spring 21 is confined on tension regulating bolt 21 between this lug and the outer face of casing 14, thus holding the guide normally fixed, but permitting it and the bar to move forward when the latter is bumped by an approaching car. The shock is thus arrested and the bar afforded such a compensating movement as to save it from injury in many cases where otherwise it would be broken. This movement of the guide does not interfere in any way with the operation ,of the bar-holding mechanism.

It is characteristic of the horn-operating mechanism of the present invention that it is all mounted on and movable with the tilting platform. I am aware that this is not broadly new, and claim novelty only for the improved arrangement of operating parts. The horns or car stops 22 each consists of a horizontal body portion having at one end the raised Wheel-engaging pertion 23. The stop is mounted between its ends on a vertical pivot 24, with the end opposite the car-holding end connected by link 25 with the inner end of bar 26, the latter being movable longitudinally of and secured to the under side of the platform (3. A spring 27 is connected to links 25 and normally holds the horns in car stopping position, with a stop 28 limiting the movement imparted by the spring. The forward end of bar 26 is connected to the lower end of vertical lever 29, the latter being fulcrumed between its ends to the extremity of tongue 10, and at its upper end carrying wheel 30. This wheel is adapted to be engaged by the under portion of a car approaching the tilting platform and is rocked forward, thus operating the mechanism which connects with the pivoted horns in such a manner as to turn the latter and release the previously emptied car and permit it to pass on to cross-over rails 9 as the next car passes onto the platform.

The platform with the emptied car may be lowered from tiltedposition by means of a power cylinder 31, having its piston connected by line 32 with the platform.
