SPECIFICATION forming part of Letters Patent-.Na 690,625, dated January '7, 1902. Appnaion ned April zo. 190iI sannita. 56,633. (Nomen.)

To @all wir/m, t mctyloozwer:

Beit known that we, JOHN C. STURGEON andv RALPH A. STURGEON, citizens of the United States,residing at the city of Erie,in lthe county of Erie and State of Pennsylvania,have jointly invented certain new and useful Improvement-s in Dumping-Cars; and we do hereby declare the followingto be a full, clear, and exact description of the invention, such as will' forming partof this specification.

This invention relates to dumping-cars, and

mbre particularly to cars provided with-oscili lating ends and center drop-bottom members adaptedto be opened'so as to'dump the central portion of the load and allow the end sec- -tions to dump the remainder-of the load.

Heretofore in the construction of dumpingcars the body of the car has been constructed of two oscillating sections pivote'd approximately near the centers thereof in the frame been made with each end pivoted at their inner ends, so that the outer ends thereof, with the load therein, have to be lifted bodily so as to dump theircontents through an opening in the central part of the car-floor, which in practical operation of cars of this character requires the use of powerful hoisting mechanism of a character which is impracticable t construct as a part of the car. v

The object ofvour invention is the construction of a dumping-car .having an open box or gondola body with a substantially level door therein throughout its entire length, so that it can be used not only to transport dumpable material-such as coal,ores,&c.-but can with equal facility be used to transport any other character of freight usually transported in open box or gondola cars. The body of this car consists substantially of stationary side sections,forx ning the central part thereof, voscillating end sections, the inner ends of ,which are overlapped: by the stationary side sections, forming the central part of the carrbody and also adapted to be lowered below the level of the car-Hoor for dumping the same, a central drop-floor section or sections between the inner ends of the oscillating sections for dumping the central portion of the 'car-body, and mechanism for locking the oscillating ends and the central drop-floor sections of the foar-body in a horizontal position. l

The construotionof this 'improved dumping-car and the mechanism thereof'are here,-

Vinaft'er fully set forth and described, and

villustrated in the accompanying drawings, in fwhichf,

.Figure l is a side View in elevation offa dumping-car embodyingourinvention. Fig. 2 is a top or plan view of the same. Fig. 3 is an .end view in elevation of the same. Fig. L is a transverse section of the car frame rand body on the line 0c in Figs. l, 5, and 6. Fig. 5 is a longitudinal section ofthe central portion thereof on the line y y in Figs. 2, 3, and fl.. Fig. 6 is a longitudinal section of the same portion thereof on the line ,az in Figs. 2 and 4. Fig. 7 is a Yplan view of the under side of the bottom ofthe central portion of the car. Fig.8isalongitudinalsectionofaportion Vof the end of the carand of the mechanism for hoisting the outer end of the oscillating carbody section on the line o o in Figs. 2, 3, and 9. Fig.'9 is an en'dyiew in elevation of said mechanism. Fig. 10 is a side view in elevation of the same.

In the drawings illustrating this invention vthe side frame A of the car wepreferably makel of metal plates cut and pressed into proper shape and provided with braces a, which are both riveted to the side sills B, which are connected by means of transverse sills C Cat the center of the frame, C C at the innerends of lthe oscillating sectionsD of the car-body, C2 C2 at the ends of the car-frame, and at such other points (not shown) as may be deemed necessary. The oscillating end sections D of the car-'body are each approximately about six-ifteenths of the length of the car-body. These sections D are provided with braces d and are of sufficient width, so that the inner IOC ends thereof will move freely up and down between the sidesA A of the car, the central portion of which form the sides of the car-body between the inner ends of the oscillating end sections D D. These sections D D are pivoted in the sides A and sills B ofthe car-frame by means of pivots d', preferably at such point that when loaded the inner ends thereof will when released automatically drop into the positions illustrated by dotted lines in Fig. l and discharge the contents thereof, and when the contents are discharged they will automatically return to their normal positions, in which they are locked by means of suitable mechanism hereinafter described.

In the drawings we have shown pinions E mounted on transverse shafts E and inclosed in cases e, provided with trunnions e', suitable for mounting the same upon a car-frame, as illustrated in Figs. 8, 9, and 10, the upper ends of the racks F being pivoted to the under surfaces of the outer ends of the car-body sections D and operated bymeans ofthe pinion E and the shafts E', extending through the centers ofthe trunnions e and through the sides of the car-hody,where they are provided with ratchets f and dogs j", by means of which mechanism the sections D can be raised and lowered by hand as may be desired.

At each side of the central cross-sills C C are pivoted drop-sections G G, which occupy approximately four-fifteenths of the length of the car-body and nearly the full width thereof and when closed and locked into place form portions of the central part ofthe floor of the car-body. These sections G G', the plate H on the top of the transverse sills C C, the plates H' H on the tons of the transverse sills C' C', and the plates d2, forming the iioors of the oscillating sections D of the car-body, taken together form a complete horizontal licor for the car-bod y. The doors G are pivotedupon transverse rods g, so that the outer ends thereof will when released drop down into the position illustrated in dotted lines in Figs. l and n'. For raising these sections G G up to their normal position links I I are pivoted thereto and pivol'ed together at their lower ends, as illustrated in. Figs. 6 and 7, and a chain t' extends therefrom to a transverse shaft I/, provided with a ratchet-wheel/L" and dog 'i2 on the outside of the frame, the ends of the shaft I being also squared,so that a crank or other suitable actuating mechanism can be applied thereto by, means of which mechanism the sections G G can be restored. to` their normal positions.

For locking the inner ends of the oscillating car-body sections D and the outer ends of the doorsG in their normal positions arms J J' are pivoted bet'ween the sills C C' on transverse rods c c, which arms J J are provided with projections j', which when in their normal positions extend through openings c2 c3 in the sills C' C and under the ends of the oscillating car-body sections D and the sections G. Between the free ends of the arms J and J' there are links K K', which are pivoted upon a transverse rod r,so that when in their normal positions, as illustrated in full lines in Figs. 5 and 6, the arms J and J are held irmlyin place, and thereby the carbody sections D and the sections G are securely locked in a horizontal position; but when the rod It is raised by the levers L L into the position shown in dotted lines in Figs. 5 and 6 the arms J J are moved back, so as to release the sections D and the dropsections G and permit them to move downward. For operating the rod 7c there are levers L L', centrally pivoted on pivots m between vertical plates M, extending between the transverse sills C and C', along the sides of the openings for the sections G, (see Figs. 5 and 7,)'and the side sills B of the car-frame. The outer ends of these levers L L are pivoted to the ends of the rods t, and their inner ends meet and are pivoted to the lower ends of vertically-moving racks N, mounted in slides ln, secured to the sides A of the car-frame. These racks N are operated by means of gearpinions N', which intermesh therewith and are mounted on a transverse shaft n, which extends out through the sides A of the carframe, where it is provided with a ratchetwheel n2 and a dog n3. The end of this shaft is also squared, so as to receive a crank or other actuating mechanism when desired,`so that by means of the rack N and the levers L L the car-body sections D D and the sections G G can be simultaneously locked in a horizontal position .and in like manner released as desired.

It will be observed that this carcan be used for carrying coal, iron ore, or any other material which can be dumped and can with equal facility be used for conveying any kind of freight usually shipped in ordinary opentopped box-cars, as when the end sections D D and the sections G G are locked in a horizontal position the bottom of the car is fiat and suitable to receive any kind of freight therein.

In operation the dog i2 being raised from the ratchet-wheel the operator applies a crank to the end of the shaft n. The dog n3 being then thrown back the shaft n' is rotated and the rack N is moved downward until the levers L L are in the position shown in dotted lines in Fig. 5. This operates, through the links K K', to simultaneously withdraw the projections j 7" on the arms J J' from under the ends of the oscillating sections D D and the sections G G, which allows them to automatically drop into the position illustrated by the dotted lines in Fig. l and dump the load from the car. If, however, the oscillating end sections D D did not operate promptly, cranks applied to the shafts E enable the operator to speedily raise the outer ends of the sections D D, so that they will dump their contents, when they will automatically return to their normal positions, and to return the sections G G to their normal positions it is necessary to Wind the chain up IOO IIC

enable others skilled in the art to which it v appertains to construct and operate the saine.

We do not, however, limit ourselves .to the.

exact construction of our invention herein shown and described, as we are aware that many modifications can be made in the construction and operating mechanism thereof without departing from the spirit of our invention. 1
