Specification of Letters Patent. Patented Mar. 14:, 1911.
Application filed August 25, 1910. Serial No. 578,828.
To all whom it may concern:
Be it known that we, Josnrrr D. HERN and- IIARRY F. VnrL, citizens of the United States, residing in Shalcr township and Etna, respectively, in the county of Allegheny and .State of Pennsylvania, have inroad freightcars, and its principal object is to provide a longitudii'rally-extensible and contractible car which can be lengthened to its full extent for carrying a load and teleextended.
scoped or contracted to its minimum length when it. is empty, so that a train of such; cars will take up much less room in freight yards than the ordinary cars now in use.
."Lnother object of the invention is the provision of a coal ore or other freight car including telescopically connected sections of novel construction which can be expanded and contracted with great facility.
1 Another object is the provision of a bottom dumping car including truck-supported end sections and a central section supported by the end sections and telescoping with re spect thereto.
With these objects in view and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth withparticularity in the claims appended hereto.
In the accompanying drawings, which verse sections, respectively, on lines 66 and 7-'T, Figs. 4 and 3. Fig. 8 is a detail view of one of the locks for holding the end sec tions in either extendedor telescoped position.
Similar reference characters are employed ,to designate corresponding parts throughout the views.
Referring to the drawings, A designates the centralsection of the car, and B the end sections thereof, the latter being supported on trucks C of usual construction. The sections A and B are telescopically related that the car can be longitudinally lengthened or shortened and the middle section A is supported wholly by the end sections.
The central section A is composed of side truss frames D which carry the side walls 1 of the section A, and between these side walls is an inverted V-shaped bottom 2 sloping oppositely from a transverse center line so as to cooperate withthe end sections of the car to effectively dump the contents through the At the bottom of each truss are bottom. spaced parallel plates 3 forming side beams which are connected to a central transverse erably of inverted U-shaped cross section' and may be formed integral with the sides 1, and these beams 7 form guides into which the side walls of the end sections slide.
Each end sectio'n-B-coinprises side and central sillsor beams .8 and 9 that are connected together by cross beams 10 and 11,
' the latter being connected with the trucks C.
The side sills 8 slide in the guideways formed in the bottom of the truss frames D of the middle-section A, while the interme- On the tral section formed by the beams 8 of the truss frames D, The side sills 8 and intermediate beams 9 of the end sections are provided with longitudinal slots 16 in which engage blocks 17 or equivalent connecting .devices on the ends .of'the side beams 3 of the truss frames D and ends of the central beam 5. The central sectionA is thus supported and slidably connected on the end sections B by the side walls 14 of the latter entering the top beams( of the truss frames D and the sills or beams-8 and 9 sliding in the beams 3 and The bottom 18 of each' end section has two sets of dumping openings l9 and-20 which are-closed by swinging .doors 21 and'22, respectively.
' The-telescoping sections of the car are locked in different positions by any suitable locking devices; In the present instance, a sliding bolt 23 is mounted on the end of each truss frame D, and on the endof the bolt isa' laterally-projecting member 24, Fig. 5,. which is adapted to engage-in either of two.
spaced notches or seats 25 formed in the bottom of the sills 8 of the end sections of the car. The upper end; of each boltis formed with an elliptical yoke 26 in which turns a cam or eccentric 27, the shaft 28 of which is journaled in a bearing 29 on the truss f frame D, as shown in Fig. 8. The eccentric isprovided with a handle 29 .so that the bolt can be operated, the. eccentric being locked by a latch 30 pivoted on the yoke 26.
so as to engage ina notch 31 inthe periph-' ery of the eccentric. 'When, it is desired to telescope or extend the car, the .levers 29 are all-thrown downwardly so as to'depress the bolts 23 and disengage the members-24L thereofl'from the notches 25 in the sills 8. If the 'cars'are to be collapsed, it is merely necessary for the engine to run backwardly so that the front .end section will slip into the central section, and then the central section slide-rearwardly on the rear end sec- -tion.' When the car is totally telescoped, the
locking bolts 23 will be opposite the outer notches 25 so that it will he merely necessary to restore the levers 29 to raised position so as to lock the'bolts.
- The swinging doors 21 for the openings 19 may be opened and closed by any suitable mechanism, the mechanism shown in the present instance, cons1st1ng-ofa hOIlZOl'l tal shaft 33 extending transversely across the end sections. and journaled in the side walls of the latter, there being crank arms 34'arranged on the shaft that are connected by links 35' with the oppositely-swinging doors 21. One end of each shaft has a squared end 36, Fig. 1, for receiving acrank, and on this squared end is a ratchet wheel 37 with which a pawl 38 engages to prevent the shaft from turning and the doors from opening when the car is lo-aded.- To open I the doors 21 to empty the load, it is merely necessary to release the pawl 38' from the ratchet wheel 37 and then the doors will open, under the superimposed load. The
doors 22-;for the openings 20 are hingedly connected to cross bars 39, Fig. 4, that are 3 fastened to the inner ends of the sills 8 of theend frames, and journaled on these bars are shafts 40 .that are provided with arms 4.1 which are connected through links-42 with theswingin'g doors 22.* Each shaft 40, as shown in Fig. 7, has a pinion 43 with which meshes a pinion 44 on a short shaft 45 to which a crank is adapted to be applied for turning the shaft 40 so as to open or close the .doors 22. When the car is telescoped the openings 20 pass underthe floor of the middle section of the car and the doors 22 are preferably opened so as not to interfere with the complete telescoping of the car by. the innermost doors striking the central transverse beam l.
Although the invention has been shown and described as a coal car, it is to be understood that the invention can be embodied in a box; flat or other car.
From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the'methodof operatiorrwill be readily apparent to those skilled in the art to which the invention appertains, and while we have I supported by and telescopically related to the end sections and forming apermanent connectlon between the latter, the sidewalls of the end sections being arranged to slide.
outside the side walls of the middle section and the bottom of the end sections being slidable under the bottom of the middle section.
'2. Arailway freight car com rising trucksupported end, sections, a mid e section-supported by and with which the end sections telescope, and locking devices for holdin the end sections in extended or telescope position, the side walls of the end sections being arranged to slide outside the side walls of the midd e section and the bottom of the end sections being slidable under the bottom of the middle section. 3.
