To all whom it may concern:

Be it known that LAVALETTE L. LOGAN, deceased, late a citizen f the United States, and resident of Robertsdale, in the county of Huntington and State of Pennsylvania, was the or1g'inal, first, and sole inventor of certain new and useful Improvements in Car-Handling Apparatus, of which the fol lowing is a specification, reference being had therein to the accompanying drawings.

The car-handling and dumping apparatus to which this invention relates includes superposed tracks upon which cars are adapted to travel and mechanism for causing a car to be transferred from one track to the other.

The object of the invention is to provide a car-handling and dumping apparatus hav ing an improved arrangement of tracks, together with means for transferring a car rom one track to another, means for effecting the dumping of the car and means for controlling the transferring and dumping means.

In the adaptation of the apparatus illustrated in the accompanying drawings, forming a part of this specification, said apparatus includes two tracks, a shiftable tracksection normally in working relation with one of said tracks and movable into working relation with the other track, and automatic means for operating said shiftable tracksection, the car being discharged while upon said shiftable track-section. In order to secure simplicity, the tracks in question are mounted in superposed relation or at different levels, the shiftable track-section normally constituting, in effect, a continuation of the upper one, so that a car can pass from said upper track onto the shiftable tracksection and after bein dumped can be transferred by said shi table track-section to the lower track.

This invention is not limited to the exact disclosure made by the drawings above mentioned and the following description, for, as the said LAVALE'I'I'E L. LOGAN is considered a pioneer, material and divers changes may be made in the character and relations of the parts, as well as other features, within the scope of the claims succeeding said description.

Referring to the drawings, Figure 1 is a s1de elevation of an apparatus involving the said invention. Fig. 2 is a plan view of said apparatus.

Like characters refer to like parts throughout the views.

The apparatus in the form thereof illustrated by the accompanying drawings, involves in its construction tracks 5 and 6, which are represented as being in superposed relation or one above the other. Of course when mention is made of said tracks being superposed it is meant that this relation is adopted .near their outer ends, for it is not essential what their relation be at a point remote from that at which the cars are dumped. The upper track is preferably at a slight downward inclination in order to facilitate the gravitation of the filled cars onto a shiftable track-section, as 7. The framework for carrying the tracks 5 and 6 and the shiftable track-section 7 is denoted in a general way by 8, and as itmay be of any suitable character a detailed description of the same is deemed unnecessary except to remark that it is provided along its top with a deck or platform 9, upon which attendants may walk to reach the cars. The shiftable track-section 7 is illustrated as being oscillatory in order that it may be tipped to secure the emptying of a car thereon.

The oscillatory track-section is suitably fastened to a rock-shaft 10, carried by suitable bearings upon the framework 8. Said oscillatory track-section 7 is normally in working relation with the upper track 5, it constituting virtually a continuation of said upper track, as seen by full lines in Fig. 1. The distance between what might be considered the inner or left end of the shiftable or oscillatory track-section and its center of motion is greater than that between the opposite end and said center of motion, and means are provided for positively preventing the depression of the left hand or inner portion of said track-section as a car enters the same, and the means illustrated for this purpose will now be set forth.

Fastened to the outer ends of the side girders constituting a part of the framework 8 is a beam or bracket 11, represented as being approximately angular in cross-section, and the horizontal web of which is in a plane under the free ends of the terminal rails of the upper track, against which terminal rails those of the track-section are adapted to abut, or approximately so when said track-section is in working relation with said upper track. The web of said beam projects outward beyond the free ends of said terminal rails and under those of said track-section when the latter is in the position shown by full lines in Fig. 1. This beam or bracket 11 constitutes a suit-able support for a latch 12, which engages under the inner free end of the shiftable tracksection 7, so as to maintain the latter in its normal position or approximately in line with the upper track 5. This latch 12 is slidable inwardly, so as to be movedv from under the inner free end of the shiftable track-section in order to release the inner free end of said track-section, whereby the left branch of said track-section, which, it will be seen, is of approximately lever form, may drop in order to bring its inner end into working relation with the entering end of the lower track 6, as shown by dotted lines in Fig. 1, so that an empty car from said track-section can pass therefrom and onto the said lower track. As the inner branch of the movable track-section moves downward the inner ends of the rails thereof pass through the notches or apertures in the outer edge of the beam or bracket 11, which notches were uncovered by the latch as it was moved into its ineffective position. This latch, as will hereinafter appear, isautomatically operated.

It will be assumed that a car has been run onto the shiftable track-section 7 and that its contents have been discharged, which operation takes'place at the outer end of said track-section: After the car has been emptied the inner portion of said track-section is caused to automatically drop to bring the inner ends of the rails thereof into coincidence with the entering ends of the rails of the lower track 6, whereby the empty car can pass from the track-section onto said lower track, it being understood, of course, that said track-section at this time is at an inclination, so that the empty car can freely pass onto thesaid lower track. The outer portion of the lower track is first at a descending inclination and then at an ascending inclination, so as to insure the travel of the empty cars onto the inner andslightly downwardly-inclined portion of said lower track.

The outer end of the track-section 7, or that branch thereof to the right of its center of motion, has a stop or bumper 13 for the cars, against which stop or bumper the forward wheels of said car are adapted to strike. This stop may be formed by curving the outer ends of the rails of said tracksection upward. Said rails at the right of the center of motion are united upon their under sides by a plate 14, to the upper side of which is suitably fasteneda weight 15, which slightly overbalances the left branch of the track-section, and the purpose of which is to return said track-section to its normal position after the delivery of an empty car onto the lower track. The right branch of the track-section should be of such a length that when a filled car is upon said track-section the center of gravity of the filled car will be to the outside or right of the center of motion of said track-section, whereby the right branch of the latter will be lowered and the left one elevated, the parts being so proportioned generally that upon such motion the track-section will assume an angle of about thirty degrees to the horizontal, as indicated by dotted lines in Fig. 1, whereby the filled car upon the tracksection will be automatically tilted, so that its contents can pass therefrom and onto a chute or runway 16, located with its entering end in proximity to the shaft 10. The chute 16 serves to receive the material dumped from the car and to convey it to a desired point out of vertical alinement with the point of discharge from the car. It will be understood that when the forward wheels of the filled car strike againstthe stop or bumper 13 the right branch of the track-section is lowered and that the left one is elevated in order to effect automatically the dumping of said car, as will hereinafter be more fully set forth.

A horizontally-disposed rock-shaft 17 is carried by suitable bearings upon the diagonally-disposed parallel struts 18, constituing part of the frame work 8, which struts are united upon their upper sides by suitable ties in order to provide a rigid structure for upholding the inner branch of the track-section when the same is lowered, as previously indicated. The deck or platform 9 at its outer end of course is cut away to permit the free downward-tilting movement of the track-section. Parallel arms 19 depend from the rock shaft 17 and are united near their lower ends by a weight 20, which normally rests against a suitable buffer on the framework 8. The arms 19 and connecting-weight 2O constitute a suitable lever for automatically operating the track-section 7 to bring the same into coincidence with the lower track 6, and the arms 19, constituting a part of the same, have outwardly-disposed angular portions connected by the cross-rod 19, which passes through longitudinal slots in the links 21. The upper ends of these longitudinal]y-slotted links are united with the eye-bolts 22, depending from the under side of the track-section 7 at the left of its axis. By this construction provision is made for a certain amount of lost motion between the lever and shiftable track-section. In other words, the connections between the shiftable track-section and the actuating shifting-lever therefor involve a sliding or loose joint.

At the opposite ends of the rock-shaft 17 are alined crank-arms 23, having pins working in longitudinal slots at the forward ends of the connecting rods 24. The rear ends of these connecting-rods 24 are pivoted to the lower ends of the crank-arms 25, depending from the rock-shaft 26. From the upper side of the rock-shaft 26 crank-arms 27 rise, said crank-arms having elbowshaped forwardly-extending branches 28, the purpose of which will hereinafter appear. At the junction of the bodies of the arms 27 with their branches 28 are pivoted the straps 29, the forward ends of which are suitably united to the sliding latch 12. The crank-arms 25 and 27 and shaft 26 constitute a rocker for transmitting the motion of the counter-weighted lever hereinbefore mentioned to the latch 12, and it will be understood that the connections between said parts involve a sliding or slip joint in order, as in the other case hereinbefore mentioned, to provide for a certain amount of lost motion of one of the parts relative to another.

The purpose of the weight 20 is to lower the left or inner branch of the track-section 7 automatically into registration with the lower track 6 after the contents of a car have been discharged therefrom and after all the wheels of said car have been replaced upon said track-section if such replacing is necessary, said weight being automatically elevated by virtue of its connection with the track-section when the inner branch of the latter is raised by a loaded car, as hereinbefore indicated.

It will be assumed that a filled car has been run from the track 5 onto the track-section 7 and that said track-section has been tipped. After the track-section has reached an angle of thirty degrees to the horizontal, as hereinbefore indicated, the car will be further tipped automatically to such an angle that the contents thereof can freely gravitate onto the chute or runway 16. When said track-section is in its normal position, the lower walls of the longitudinal slots in the links 21 will be in contact with the cross-bar 19', so that the instant that the left branch of said track-section is elevated a corresponding motion follows with respect to the weight 20 through the elevation of the arms 19. The weight will be carried toward the horizontal line, it being understood that the load upon the track-section at the right of the center of motion thereof overbalances said weight 20. The moment of the weight 20, however, when the latter is in its elevation position exceeds that at the right of said center when the car is empty. As soon as the car is emptied, it is swung downward, if necessary, by an attendant, so as to bring its rear wheels onto the track-section, and when this condition is reached the weight 20 can lower, and as it does so it pulls down on the links 21, and hence on the left branch of the track-section 7. As the downward movement of the weight 20 is an accelerated one, it will serve to carry said left branch downward to bring the inner end thereof into correspondence with the outer end of the lower track 6, it being understood that the latch 12 has been thrown to its ineffective position during the initial upward movement of the track-section 7. As just stated, the weight 20 during its descent has a rapid motion, so as to impart, through the intermediate connections, a corresponding motion to the shiftable track-section, whereby when said weight strikes its bumper (at which point the tracksection will be in horizontal. position) said track section will be carried by its momentum into registration with the lower track. The latch 12 is operated from the weighted arms 19 mentioned. As the said weighted arms 19 are moved upward they serve,

through the intermediate crank arms 23, to

draw the connecting-rods forward, whereby through the agency of the straps 29, operatively connected, as hereinbefore set forth, with said rods, the latch 12 is moved from under the inner free end of the track-section. As the latch upon the initial movement of the track-section is thrown to its ineffective position the left branch of said tracksection may be lowered by the falling weight 20 in order to permit the rolling of an empty car from said track-section onto the lower track. As soon as the empty oar passes from the track-section onto said lower track the weight 15, which at this time is in its elevated position or that of its highest efliciency, can lower in order to return the track-section to its initial position, with the inner free end thereof in line with the upper track 5. \Vhen the weight 20 was elevated in the manner hereinbefore described, the arms 19 acted, through the intermediate connections, to draw the connecting-rods 24 to the right to shift the latch 12 into its ineffective position. By virtue of the sliding or loose connection between the crank arms 23 and said rods 24 said weight as it returns to its initial position to efi'ect the automatic operation of the track-section will not thrust the rods 24 rearward or to the left, as in case it did the latch would be put into its eflective position to block the complete return movement of the shiftable track-section 7. Means operative independent of said weight 20 are provided for returning the latch to its normal or effective position. When the weight 20 strikes its buffer the pins atthe free ends of the crank-arms 23 will be at or near the inner ends of the slots in said connectingrods, said pins traversing said slots during the falling of said weight. The free ends of the angular branches 28 as the rods 24 are drawn toward the right under the action of the ascending weighted arms 19 are elevated to a point above the top of the track 5 and in position to be engaged by the treads of the forward wheels of a filled car, it being understood that the said free ends are located back of the junction between the free end of the track 5 and the inner free end of the track-section 7. Of course, the free ends of the branches 28 are maintained in this position until they are engaged by the treads of the forward wheels of a filled car. As soon as said treads strike said free ends the branches 28 will be lowered to their initial positions, whereby the. crank-arms 25 are swung toward the left, the rods 24 moving into corresponding directions, so as to carry the outer ends of the slots in said rods against the pins at the free ends of the crank-arms 23. During the lowering of said branches 28 by the wheels the rods or straps 29 are thrust toward the right, so as to carry the sliding latch 12 under the inner free end of the track-section 7 which latter in the interval had resumed its primary position. By virtue of the loose connection between the track-section 7 and the links 21 the inner branch of said track-section can have a lowering movement without imparting a thrust to the weighted arms 19. During the ascending movement of said inner branch under the action of the weight 15 the links 21 will have an ascending movement relatively to the at this time stationary weighted arms 19, and when the track-section reaches its normal position the lower walls of the slots of said links will strike the cross-bar 19 in order to positively arrest said track-section when it reaches said normal position, it being understood that the weight 15 underbalances the weight 20.

It will be observed that in the form of apparatus illustrated, the center lines of the two superposed tracks, the center line of the pivoted track-section and the center line of the material receiving chute are all located in the same vertical plane. I prefer this particular arrangement of parts for the reason that the construction is then much more simple and compact than it would be with any other arrangement. The framework necessary for supporting the tracks and the chute is a very simple one and the construction has the further advantage that neither the car nor the material within it need be deflected laterally at any time during the operation of the mechanism.
