To aZZ whom it may concern.-

Be it known that we, JOHN PHILLIPS, residing at Garrick, Baldwin township, JOHN J'. FLEMING, residing at Fleming Park, and FRANK BROWNING, residing at ,Ooraopolis, in

the county of Allegheny and State of Pennsylvania, citizens ofthe United States,haveinvented certain new and useful'Improvements in Automatic Cross-Over Car-Tips; and we [0 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. This invention relates to a cross-over car tip or dumping apparatus, for the rapid and economical handling of cars at mines, in which the loaded car passing on to the tip or tilting track section of the apparatus is stopped by the horns, the tip being released, dumps the car, the contents thereofbeing discharged between and below thetrack rails, the tip auto matically coming back. to first position. The next loaded car as it comes to the tip, auto- 2 5 matically opens the horns, thereby releasing the empty car, which passes forward off the tip and the horns spring back to the first position to catch the next approaching loaded car. Said movements of cars loaded and empty are caused by gravityeffected by a proper arrangement of tracks and switch.

To bring about the above operations, the invention consists of, andcomprehends a novel construction, arrangement and combination 5 --of parts hereinafter fully described, illustrated andclaimed.

In the accompanying drawings, Figure 1 is a side elevation, partly in section'of the tip in its first position with the car thereon, the 0 dotted lines showing thetip in its second position dumping the car, the horn spreader, howeverfnotbeing shown in dotted lines. Fig. 2 is a top plan view of the tip, showing the parts in the same position they occupy in Fig. 1, the car however, being removed. Fig. 3 is a detailed transverse sectional view,.on line A'B of Fig. 1. Fig. 4. is a side elevation showing brake lever. Fig. 5 is a detail (No model.)

in perspective of the horn mechanism. Fig. 6 is a side elevation of the automatic horn spreader. Fig. 7 is a sectional view of the automatic horn spreader on line OD of Fig. 6. Fig. 8 is a plan view partlyin section of a portion of the tilting track section or tip.

Referring to the accompanying drawings, E represents timbers of the usual type which support the tip. E the 'floor, secured to these timbers, upon which are secured the main stationary track rails F, leadingthe cars from the mine to the tip. The loaded car moving on the stationary track from the mine to the tip, strikes the horn spreader placed on said track at any desirable point, pushing it forward and down, thus passing over it on to the tip. Upon the tip are located horns H for the purpose of stopping the'car at the desired point on the tip preparatory to dumping. The horns H are connected to rock shafts which are journaled in boxes 1 on the movable track section andthese shafts are caused to rock or partially revolve by mechanism hereinafter to be more fully described and designated generally as the horn spreader. I The horn spreader is located wholly on the tilting track section while its actuating mechanism, preferably a depressible tread rail and adjuncts, is located upon the stationary track section, the tread rail mechanismbeing connected to the horn spreader by a chain, so that as the loaded car passes over and depresses the tread rail, the horns will be spread apart by the horn spreader.

The track on the tip isformed of steel angle rails G, upon which the car moves until stopped by the horns The brake handle I, is then pulled back by the operator, releasing the brake bar J, from the bite of the brake shoes a, by which said brake bar is held as will be hereinafter more fully described, which operation causes'the tip to rock forward and down upon the tip shoes K, to the position shown by the dotted lines in Fig. 1. The brake is then applied to hold the car in tilting position, until the contents are all discharged. The brake then being re- 9 5 leased, and the tip being so balanced within itself, returns with the empty car to its first position, the brake locking automatically, to hold the tip for the coming loaded car. The nextloaded car moving by gravity toward tip, operates the horn spreader, causing the horns to roll outwardly and release the empty car.

The grade of the tip is such as to allow the empty car to move forward ofi the tip by gravity, without being pushed by the loaded car, and at the instant the rear wheels of the loaded car clear the tread rail of the horn spreader, the empty car has passed the horns, which right themselves in readiness to catch the approaching loaded car. The empty car passes from the tip across the hinged sliding rails L, to the permanent track M, where by a combination of grades and return spring switch, it is run back to the mine on a track parallel to the stationary track F.

Having thus described the working of the.

detail parts in combination and arrangement, the following is 'a description of the mechanical'details.

Referring to Fig. 2 of drawings, a section of one of the main stationary rails is cut out at any preferable distance from the tip to accommodate the tread rail of the horn spreader, which forms a continuation of one of said rails. The base plate a of the horn spreader, which is slotted to accommodate the movements of the upright pivoted arms I) c, is securely fastened to the floor E. Riveted to the top of said base plate are the angle bars (Z. To the bottom of the base plate a, are riveted the angle clips 0 in which are pivotally secured the arms be. Pivotally secured to the upper ends of the bars I) c is the tread ra'il f, which is designed to register with the angle bars d, to form a section of the stationary rails F. Secured to the up right bar I) at g is the drawing chain it. To the lower end of the bar 0, is attached the slotted counter-weight 11.

It will readily be seen from the above description, that as the loaded car comes from the mine, the tread of the front wheel pushes the tread rail f, forward and down until it registers with the angles d. As the rear wheels of the car pass the tread rail, the counter-weight t, and the retractile spring 25, to be hereinafter described, bring the horn spreader into first position.

The base of the tip proper is a heavy steel platej (see Fig. 2), the purpose of which is to insure foundation of absolute rigidity, to which is attached the track rails, tip shoes, sliding rails, rolling horns, and brake mechanism. Securely riveted to the top of the said base plates are the angle track rails G which are formed of two angles, which are also riveted together. These track rails are only long enough from the horns back to accommodate one car, the idea being to make the tip as short and compact as possible.

The shortening of the tip would not be possible if it were not for our placing the actuating mechanism of the horn spreader on the main track. The top angles'are cut away as shown at 75, to allow the horns H when in their upright position, to engage the tread of the front car wheels, close to the flanges of same. Riveted to the base plate j, are the horn journal boxes Z, in which are pivoted the horn shafts m. Securely welded to these shafts are the horns H. On the ends of said shafts are the collars n secured by keys. On the shafts between the collars and the next journal boxes, as clearly shown in Fig. 5, are spiral springs 0, designed to take up the jar caused by the loaded car striking the horns, the slots being long enough to allow aslight forward movement of the horns. Securely keyed to the shafts m are the crank levers p,

the plate j being slotted to allow the neces sary movement of said cranks. To the lower ends of above cranks are pivotally secured the jaw rods Q, the other ends of said jaw rods being pivotally connected to the T crank r, which is pivotally secured to the base plate j byabolt through the clip 5', which is riveted to the base plate. To the third arm or stem of the T crank r, is attached one'end of the spiral, retractile spring t. The other end of said spring is secured to the angle a, which is riveted to the forward end of the base plate to strengthen same. Attached tothis same stem of the T crank r, but on the opposite side, is the spreading chain It.

From the above description it will be readily seen that as the loaded car coming from the mine pushes the tread rail f of the horn spreader forward and down into alignment with the main track rails, as shown by the dotted lines in Fig. 6, the chain It draws the stem of the T crank 1' toward the horn spreader, thereby drawing the jaw rods Q inwardly, and thus rolling the horn shafts in their journal boxes and spreading the horns H outwardly from in front of the wheels of the empty car. When the empty car has cleared the horns, and the loaded car has passed the tread rail of the horn spreader, the retractile spring t immediately brings the horns back and securely holds them in their upright position to catch the loaded car.

Riveted to the bottom of the base plate j is an angle stiffener 'v. Securely riveted on the top of said base plate j and through the angle '0 are two steel angles which are also riveted together with fillers between, which together form the brake tongue N. Upon the free end of said tongue is placed, as clearly shown, a spiral spring to, resting on a plate 00, riveted to the bottom of said tongue. Depending from a washer placed on top of, said spiral spring, and through the spring and base plate, is an eye bolt y, to which is pivotally hung the brake bar J, said spiral spring being so placed to take up the jar caused by any sudr the tip shoes K as den application of the brake. The construction of tongue N is'also such as to make a compensating spring for the same purpose. The brake appliances for gripping said brake are of the usual character, and are clearly shown in Figs. 1', 2 and 3. Securely bolted to an intermediate timber is the base plate a, which is provided with six auxiliary projecting arms, the lower four of which form two opposite side slots, in-which' work the brake shoes a, between which passes the brake bar J. The inside shoe is designed to take the wear off the base plate. Between the u pper two arms of said base plate pivotally depends the cast fulcrum b, in which is securely inserted the lever 0'. Depending from the outward end of said lever is the cast weight cl which tends to compress the brake lever between the shoes, thereby gripping the brake and locking the tip in any position. To raise the lever c, and release the-brake, we employ a bell-crank 6', drawing rods f, brake lever I, and the guard g as clearly shown in Fig. 4. The brake locks automatically.

Referring to Fig. 2, the adjustable tip bar h, is bolted to the bottom of plate j. The ends of said bar project beyond said plate, and are securely inserted in and bolted to the tip shoes K. Means for moving said bar forward or backward to adjust the tip to handle cars of various weights and wheel bases, are

provided by a series of holes in said plate 3', as clearly shown. Securely bolted to the timbers E, are the shoe bases '5', which are provided with cogs which mesh with recesses in they rock forward in tipping the car. When said tip shoes are at rest, and the tip in its first position, the line of gravity of the tip and loaded car is forward of the point of contact of the tip shoe on the base plate. As the tip rocks forward and down on the tip shoes, thereby dumping the loaded car, the center of gravity moves back of the then point of contact, so that the tip with the empty car rights itself automatically. Y Y

At the forward end of the angle track rails G, said rails are separated and forged to form slots j, in which are securely hinged by means of bolts, the sliding rails L, on which the empty car crosses over the dump hole to the permanent track M. The free ends of said rails are held in gage and alignment with the track by the boxes Z which are provided with friction rollers 'm, on which the said rails slide to accommodate the downward motion of the tip.
