.FRANK S. INGOLIDSBY, OF ST. LOUIS, MISSOURI, SSIGNOR TO THE ING-OLDSBY AUTO- '.WHITIC4 CAR COMPANY, OF ST. LOUIS, vMISSOURI,

ernia.

A CORPORATION OF WEST VIR- DUMP-CAR.

Specification of Letters Patent.

Be it known that I, FRANK' S. iIneonnsr, a citizen of theUnited States, .residing at St. Louis, State of Missouri, have invented -a certain new and useful Improvement in Dump-Cars, of which the following is a full, clear, and exact description. reference Y being had to the accompanying drawings.

The object of this inventionisto provide very simple and eilective mechanism for raising the doors of dump cars.

The invention is well adapted for cars of the Ingoldsby type,`wherein there is a longitudinal center member to which are hinged dumping doors which form all or a portion of the load carrying floor of the car and swing downwardly at-Atheir4 outer edges-to discharge the load. Insuch cars it has been customary to support vthe doors by means of hooks pivoted along the side of the car and engaging floor beams on the under sides of the doors, the upper ends of these hooks' being connected with a pivoted operating lever, whichV is thrown in one direction to- ,cause the hooks to engage and in the opposite direction-to release them. I have discovered that this same operating lever may be used to operate a mechanism to raise the doors.' y vSuchan arrangementiis' the s ubject of the present application.

- This invention includes broadly the combination of releasing mechanism, raising mechanism and a common operating member therefor. It includesmoreover the particular embodiment shown in the drawings and hereinf after more fully described, thou h -it is to be understood that numerous m iiicationsA of this embodiment may be'. made Without departing from my invention'. i In the drawings, Figure 1' is a side elevation of substantially half a. car embodying my invention; Fig. 2 is a cross section thereof; Fig. 3 is an end view; figs. 4 and 5 are details, being vertical sections `substantially on the correspondinglynumbered lines of Fig. 1.; Fig. 6 is a detail'ofra slightly modified form of pulleywhich may be employed in the raising mechanism. f y

Referring' to thepartsjby reference nu-l morals, 10 represents the side-of a car which is shown as a plate girder, having ya lower.

" chord 18, an upper chord A,i9 and vertical tion shown in Fig. 1 extending in the direc- Application-filed A11-gust 24, 1907. Serial No. 339,939.

stilieners 17; 11 represents the central longitudinal member, which is shown as ridgeshaped, and 12 the dumping doors hinged to the central longitudinal member, and adapti ed to extend outwardly to the car sides. 13 represents` 'an inclined end oorand 14 a' cross beam orv a member. The car shown is thus divided into four hoppers, and the load is normally supported by the dumping doors and the inclined walls of these hoppers.

It is to be understood that the present invention is not concerned with theinterior of the car, which may be made in hoppers as illustrated, or may be a level bottom car wherein the doors constitute substantially the whole of the bottom, or it may be constructed in other form.

l Pivoted to the sides ofthe car are hooks or levers 20, the .lower ends of which are adapted to engage beneath floor beams 21 on the under sides of the doors. The upper ends of these hooks are connected by a horie zontal bar 22.1which is connected by a link 23 with an operating lever 24. This lever is pivoted at' a lsuitable point, the arrangement shown Vbeing by means of a bracket 25 secured to the end strut 26 of .the girder side.

The pivoting may be made directly to the.y i

car side, or in any other manner desired.

vIt will be seen from the structure described, that, when t-he lever is in the position toward the extreme end of the car, the hooks engage beneath theyloor beams and support the doors. When the lever is thrown forward the books are withdrawn from the floor beams and the doors dropped. This isV the usual arrangementin I-ngoldsby cars. i v

To raise the doors I provide the follo'wing very simple mechanism: Secured tov each door are two or more cables, chains or flexi ble members indicatedl by 30. These flexible members pass upwardly over suitable pulleys 31 and then extend horizontally toward the end of the car. These pulleys 31' are so formed as-to carry also a longitudinal bar 32, which (as shown in Figs. L5) may be in Athe form of a channel-bar, with its flanges facing downwardly. The upper ends These teeth may be made ina solid bar 34 extending withinand secured to the channel U32. Pulleys 57, s`imilar to pulleys 31 are v.provided at close intervals beneath the tooth lbar 34, to effectively support it.

In the vpresent invention, the operating liever'24 extendsbelow its pivot 25 and' to :such extension is pivoted, an operating pawl jfteeth 3 3.l 36 4represents a detent pawl verrtending cross-wise of .the car, and adapted to engage the teeth 33. This detent pawl-is Vshown as being ,pivoted to a'bracket `37 se` curedto the channel beam '16 vwhich .constituteSf-an, extension of .theside-sill. The

v,pa'wl. 361 rests against the outer face of the vertical strut 26.' d d Y Now, with the abovedescribed construction, if the doorshave been dropped to discharge theload, they may be easily elevated by oscillations of the operating lever 24. AThe forward inovement of the upper` end of'that 'lever towardthe center of the car. shoves the bar`v32 toward the -end ofthe car, drawL .ing upwardly on the cables and elevating the door. At the end of the stroke the gain made is secured by the detent pawl 36, the inner end of which is drawn upward `by the operators foot, so lthat the pawl-nose engages the teeth 33 andv prevents backward movement of the longitudinal bar. As the lever ismoved backward, the pawl 35 clicks idly over the teeth 33; then, `on thenext stroke, the door is further elevated, and so on, by successive oscillations until the door lbeams slightly and" brings the doors snugly into position. ,'This same movement releases the-tension on the iexible members which releases the pressure on thel detent pawl 36.

'As soon as the operator removes his .foot

from ,beneath this pawl, the superior weight of its inner end swings this 'end downward whlch raisesv the rear end of the pawl 35 extending above the detent pawl, thus freeing to the doors.

the raising mechanism. The parts thus automatically assume position for the next releasing of the doors, as soon as the'doors have been raised and locked.

If desired, suitable guide pulleys 40 may be provided tor the exiblev members 30 to bend against in passing from the pulleys 31 In the drawings these pulleys are,..shown as mounted in suitable brackets 4l riveted to the lower chord 18 on car side.

' In Figs. 1,-5 I have shown the pulleys 31 as being journaled on bolts' 43 mounted in brackets 44 riveted to the car side. I`his construction may be employed where 1t 1s desirable, to locate the longitudinal bar 32 outside of the stiieners 17 or other members ofthe car. In some forms of car, however, it may be desirable to locate this member closer to the car side, in which case the pulthem and being formed with an eye 50 extending around a bolt 51, connecting the bars ,32. Whether the pulley and longitudinal -member take the form shown in Fig. 4 or Fig. 6 depends on the convenience of construction. In either event space is provided for the cable, and flanges 55 are provided by the pulley for guiding the longitudinal member.
