iner positions, a weight 55 being provided to insure the prompt performance of this movement.

As heretofore stated, that portion of the platform which is over that portion of the pit or chamber in which the car is placed to be loaded where said car emerges, is hinged, and capable of being raised. This is so that the loaded car may emerge without having the heaped-up portion of its load scraped as as it begins its ascent. After the car has been loaded, this platform portion is raised, by hand or otherwise, and will be held to its raised position by means of the prop or support 2i, as is best shown in Fig, a, so that the car and its load may freely pass. in order that it may be caused to drop down, ready for use, promptly when the car returns for another load, I have provided a means by which the car will auto-- matically throw the prop back as said car reaches its loading position. This means consists of an arm (51 secured to the side of the car in such position that it will come in contact with said prop, and move it back, as will be readily understood. In order that said arm maynot. operate when the car is moving in the other direction, and thus be likely to do damage, 1 have mounted it on a pivot at 62, upon which it will swing when it comes in contact with any obstruction. It is held normally to its extended position by a spring 63.

In order to stop the car at the proper point, I have provided within the pit or m'aer into which the car enters a fricc tion i retarding device in the nature of a brake. This consists of a bar 71 pivotally connected at one-end, as by pivot 72, to the wall of the pit or chamber, and having a spring or other suitable downwardly-forcing device, as 73, by means of which it is forced downwardly with such pressure as may be desired. As the car enters the pit or chamher and approaches its final position, the wheels of said car will come in contact with the bar 71, and be thereby retarded, and the car (the pressing force being predeterminedly arranged) will stop the car at the proper point.

Having thus fully described my said in- .vention, what I claim as new, and desire to secure by Letters Patent, is

1-. The combination, in an elevating and loading mechanism, of a suitable pit orchamber having an opening in its upper wall, a track leading therefrom to a suitable elevation, a car adapted to travel on said track from said pit or chamber to the extremity of said elevation, the upper portion of the track being pivotally mounted at a point midway of the car when the latter is in dumping position and provided with suitable retaining devices for the car. and means for tipping said upper track-section and the car whereby the contents of said car may be discharged, substantiallv as set. forth. if

.2; The combination, in an elevating and loading mechanism, of a pit or chamber adapted to contain a car and provided with an opening in its upper wall. through which the car may be loaded, a track leading from said pit to a suitable elevation, 21 car adapted to travel on said track from said pit or chamber, said pit or chamber being also provided with a portion capable of being raised arranged over thatvside of the pitor chamber from which the car emerges, a sup port for holding saidv raisable portion in its upon one side of the car whereby said support will be pushed from its upright position as the car enters the pit or chamber and the said raisable platform portion thus permitted to descend to place.

3. The combination, in an elevating and loading mechanism, of an inclined track having a pivoted upper section onto which the carrier car may run, a pivotsnpporl for said upper section arranged centrally thereof, guard rails secured to said upper track section beneath which the wheels of the car will pass whereby said car will be held securely in position thereon, means whereby said track section with the car thereon may car thereby be discharged of its load, and means for returning said car and track section to initial position, substantially as set forth. M I

:l. The combination, in an elevating and loading mecl1anism .ot an incl'incd track embodying a tilting portion centrally pivoted, a guard rail secured to said tilting portion. power devices attached to the rear end of the car for propelling said car and tilting the same together with the tilting portion of the track, and means con'iprising said power devices and a weight suspended. directly to the rear end of the tilting track portion for returning the tilting portion of track and car to initial position when the load is discharged, the whole being arranged and operated substantially as shown and described.

In witness whereof, I, have hereunto set my hand and seal at Harmattan, Alberta, Canada, this fourteenth day of August, A. D. one thousand nine hundred and eight.
