Specification of Letters Patent. Patented )hug 29, 191() Application tiled December 26,1907. Serial No. 408,031.
'l'o all whom it lmay concern:
Be it known'that I, FREDERICK Simeone., a citizen of the United States, residing at Chicago, in the county of Cook and State ,of Illinois, have invented certain new and useful Im rovements in Dmnp- Cars, of which thel ollowing is a'specification.
The object/1. of my invention is to provide an improved door operating,mechanism esi pecially adapted .for that type of dump cars having drop doors in the bott-om thereof, and also to provide an improved cover plate at the center of the car adapted to prevent V the contents of the car from enterlng the space behind the hinged edge of the door.
In the drawings-flignre 1 is a cross section of so much of a floor ot' a dump car as is necessary to illustrate my improvements. Fig. 2 is a plan viewuoif the central part of one of the cross beams showing 'my imlet't, thus causing the load ot' the ear to impose a strain on the guide rails which they arc'not calculated to withstand. guide-rails throughout the length of thc car Jnust be constructed in thc same plane, the entent to which the guidc-rails can project downwardly is limited by the form of the `guide rails over the trucks. 4 It is to obviate these,disadvantages, and to rovide an in1- lproved cover plate between tie inner edges 'of the door along the center of my improvements are designed.
In the structure illustrated in the drawings the central longitudinal support or center sill ofthe car consists of two channel irons 2, spaced apart and connected at intervals by plates* 3. cross" beams 8 reinforced at their upper edges by channel irons 4. The cross beams 3 are secured tothe center sill`2 by means of proved cover plate. Fig. 3 is a side view of angle irons. ,Sloping inwardy and upthe center sill showing the supports tor the wardly 'trom the outer lsides o the center sill andlrivoted to the flan es of the channel yirons 2 are supports 6, an extending longitudinally of the center of the car are T-irons door hinges and my improved cover plate, together with themeans of attaching the same to the remainder of the car structure..
My improvement is especially adapted tor use in *that type of cars wherein the dump doors, or hinged floor sections are operated by means of a transversely movable shaft, such as that designated by the numeral l upon the drawing. l, Y,In cars of this type the transversely movable shaft moves upon a guide rail which extends transversely of the car from the outer odge toward the center. The outer part of this rail is usually hori- 'zontal in order that the door may' helirmly supported when the transversely movable shaft is in its outer position. A ca r having a track rail ofvthis general type is illustrated in the patent to Otis No. 823,(3Zlt, July 11),' 1906. The guide-rail slopes downwardly from the side otE the ce r toward the center, thus permittingthe door to drop when the Shaft is moved toward thc center ot' the car. In practice it has beeii found that the guiderail'sometimes meets with injury owing to its exposed position, sloping dmvnn'ardly as. l it does below the tloor of the car. The guide-rails located near the ends oli` the car over the trucks must be constructed to leave about two inches clearance between them ot' these T-irons is secured vbetween the upper ends of the members 6 by means of rivets and the to i of the T-iron 7 is flush with the upper sur ace of the cross beam 3 .und its reinforcing angles 4. The T-iron 7 forms a cover plate projecting over the inner hinged edges ot' the doors S). The T-iro cover plates T are constructed in sections, each section extending between two adjacent cross beams, and the T-irons T are ported by the inclined members (i, but are also secured to the cross beams 3 by means ot angles l0, which are riveted to the T- irons and through the'cross beams 3 and their reinforcing angles The doors 9 are, in the present. instance, in'ovided with pintles 1l which coact withhingc members l2 riveted to the inclined support G. The relation of the inner edges of the doors and the cover plates T is such that: the cover plate extends over the inner edges of the doors both in open and closed position.
Fixedly secured `to the car at the side thereof is a fixed member 14 forming the outer part of the support for the transversely movable shaft 1. 'llheuppersurface of the part let. at thc point 15 1s substantially horizontal in order that the shaft may have no tendency to roll inwardly and as the settling yof the car upon the springs would cause the guide-rails to contact 'with the arch bars unless suieient clearance were As all the the car that Supported by the center sill 2 are.
t. 'lhe downwardly extending web of eachmoved to closed position.
permit the door yto "open after it has been The inner inclined part of` the support for the shaft 1 instead of being formed as a rigid or integral.` part of the car structure takes the form of a pivoted guide-rail 16, which by means of the mechanism hereinafter described may assume eithei` the position shown in dotted lines in Fig. 1, orthat shown in solid lines. The guide-rail 16 is connected near its outer end by a pivot 17 with the inwardly extending part of the support 14, and its outer end projects beyond said pivot and is so formed that 'when the transversely movable shaft l is moved to its outer vposition it contacts with said outwardly extending free end of the guide-rail 16, thus depressing said outer end and raising the inner end from the position shown in dotted lines in Fig. 1 to `that shown lin solid lines. When the guiderail 16 is in its lower position, that ilhistrated in dotted lines in Fig. 1, it is su ported by means of a link 18 pivoted to t e ciossbeam at.19 or to some other fixed part ol the car underfrarne'. y In order to permit the guide-rail 16 to move to its upper position the lower end of the link 18 is connected thereto by means 4 of `a in'v and slot connection. 'In 'the` resentl v1nstance', the slot is formed inixthe ink' 18" andthe pivotlpin' 2O pass'estlirou 'l ecured to tliei'i'nner yenf` 'of'th It 1 will be observedfthat" when the transversely movable v"s hailtg is moved from the position shown in dotted lines in Fig. 1 it will coact with the track 16 Land the inclined guide-railv 25 causing the door to rise to closed position, and that when said shaft 1 f reaches the rigid part 114 of its support it will contact withthe outwardly extending free end of the guiderail 16, thus depress' ing said outer end and raisin the inner end to the position shown in soli lines in Fig.` v1. By means of this construction the guiderail 16 may be so formed that in` the lower position it will come practically down to the arch bars lof the truckframesT there being no danger ofbreakage upon depres sion of the car under itsload, for the reason that in my improved construction. the track rails could yield 4upon their pivots under such pressure. It is1 therefore, ossibIe to secure an increased movement o the door? and a lar er door opening, thus securing" .a more eiectual dumping of the .contents of the car.-v y

operating member movable transversely of the door, and a movable rail adapted to support said operating member.
2. In a car, a door, a hinge therefor, an operating member movable transversely of the door, a movable rail adapted to support said operating member, and means to move said vrail tovvard said door when the latter is moved to closed position..
