Specification of Letters Patent.

Patented Sept. d, 1919.

Application elec April ao,l 1910. serial No. sisef/ea To all 'whom u may concern Be it known that we, WILLIAM Gr. CRAIG, a resident of Marshalltown, in the county of Marshall and State of Iowa, and AUBREY R. RAMSDELL, of Toledo, in the county of Tama. -and State of "Iowa, both citizens of the United States, have invented a new and which may be Improved Door for Grain-Cars, of which the following is a full, clear, and exact description. y

Our invention relates' to' doors .for grain cars, and it'has for its object to provide doors which are simple inconstruction and manufactured at little 'eX- pense. i v

`Another object ofthe invention is to provide a central hingedpost, and two doors pivoted on horizontal axes, which are adapted to engage aslot in the hinged post and be secured thereto.

Still another object of the invention is to v provide means by which the doors are held in position relatively to the side of lthe car, to prevent grain :from working through the doorway.

Still other objects of the invention will appear inl the following complete description. v In this specification .we will describe the preferred form of our invention, -it being understood that the scopeof the invention is defined inthe appended claims. Reference is to be had to the accompanying drawings forming a part of this speciiication, in lwhich simi-lar characters of reference indicate corresponding parts in all the'views, and in which- Figure l is` a sectional View showing al doorway in the side of a ear, equipped with our improved doors; Fig. 2 is a sectional plan view of the side of the car as equipped withlour doors; Fig. 3 is a transverse sec- 'tionalv view showing a portion of a car in Whichour improvements are installed; Fig. 4'is a sectional view on the line 4 4 of Fig. l Fig. 5 is a sectional viewon the line 5 5 of Fig. 2; and Fig. 6 is a fragmentary view of the plate secured to the bottom of the doorway, having a projection with a ref cess in which the lower terminal of the central post is normally disposed. l

- By-referring to the drawings it will be seen that the car 5 is of the usual type, the,

car vhaving a doorway, at the sides of which there are disposed the usual door jambs 6,

which there is a recess 9. To the inner sides 4of each ofthe door jarnbs 6 are secured two plates 10 and 11, the plates 10 being disposed. against the door jainbs 6 and the plates 11, which are preferably constructed of angle iron, being spaced' from the plate 7 and having pivoted between them doors 12. rThe plates 10 and l1 lare connected together at their upper'terminalsby bolts 13 which project through orifices in the ,door j ambs 6, there beingnuts, which are disposed in recesses inthe said door jambs, by which the bolts 13 are held firmly in place. The plates 10 and l1 are connected at their lower terminals by bolts 14, these bolts14 being disbolts 14 also being disposed through the door jambs 6 and being held in place by nuts 16 which are disposed in recesses 17 in the outer walls 18 of the car. The doors 12 arel rectangular in shape and have lugs 1Q which tit the recesses 11a in the plates 11, the plates 11 limiting thev movement of the doors and preventing them from bulging outwardly, when they are secured to the central post 20.

The central post 2O is bent around a rod 2l secured to the car above the doorway, members 24 of the central post 20, at one side of its bent portion, being disposed substantially parallel to each other, there beingl a slot 22 between the members 2i, for engaging t-he doors 12 when they are closed.v The lower terminal of this central post 20 is adapted to be disposed in the recess 9 in the projection on the plate 7, the bottm of the central post abutting against the plate 7 which prevents it from moving outwardly. ln the members 24 of the'central post 20, at their lower terminals, are orilices 23, which are in alinement and in which is normally disposed a pin 25 which is secured-in place by a key 26, which engages a slot in'the said .posed through orifices 15 in thedoors 12, the

pin. The doors 12 haverecesses 27, in which the pin 25 is disposed when the doors 12 are closed.V The outer member 24 of the central f post 20 has outwardlyextending iianges 28 which aiiord strength to prevent the central post from buckling under pressure of the grain against the doors. Thedoors 12 also have`porioes"23=which register with orifices 30 in the-members 24 of the' central post 20 when the doors arevclosed, a pin .31 beingnormallyl disposed in these orifices 29 and l movement of the doors, a central post se- 30, the pm 3l having a slot in which is disposed a key 32 by which the pin is held in l place. The key 32 is secured lo the outer member 2 4 of the central post 2O by means of a chain 33 and the pin 31 secured to the inner member of the key 32 by means of a similar chain 34. There aretwo additional orifices 35 in the outer member 24 of the central post 20, the center of one of .these orifices being slightly out of alinement with the center of an orifice 36 in one of the doors, the center: ofl the other' orifice 35 rbeing slightly oiit of alinement with the center of an orifice 3T in the other door.

When the central postand the doors are constructed and are mounted as has been de- `"scriloed,it will be readily understood that, vwhen the doors are swung on their pivots away from the central post-20, and the cen-V orifices 30 in the members 34 of the central post 20. The pin 3l is thenintroduced in these orifices 29 and 30 and it is held inplace by the key 32. The door vwill then be found to be held firmly in place in such a manner as will prevent any possible leakage of the grain. To open the door the pin 31 is removed, when it will be aossible to insert a pin or spike in one of tie orifices 35, so that the pin will engage vone of' the doors 12 at its orifice 36,' and, by lifting the pin or spike, the door may be loosened so that it may be readily raised and thrown back. In a similar way the door may be free from the central post. The flanges 28 on the central post will prevent it from buckling, and in a similar manner the flanges 38 on the plates l1 will prevent them from' buckling.

Having thus described our invent-ion, we clann as new and desire to secure by Letters Patent:

' l. In combination with a car having a doorway, two doors, one pivoted at each side of the doorway, lugs on the doors respectively, members at the sides of the doorway, for engaging the lugs and limiting the cured to the doorway, and means for securing the doors to the central post when the lugs are in. engagement with the said niembers.

In combination with a car having a doorway, two doors, one pivoted at each side ofthe doorway on horizontal axes, a central posthinged on a horizontal axis and at right angles to the axes of the doors, and means by which the doors may be secured to the central post. A

3. In combination with a. car having a doorway, two doors with recesses, one pivoted at each side vof the doorway, a central post secured to the car at the doorway, haw ing two members spaced apart, between which edges of the doors may, be disposed, and a bolt secured to the central post, from one of theclnembers to the other, which is normally disposed in the recesses in the doors. e

4. In combination with a car having a doorway, two doors with recesses, one pivoted at each side of the doorway on horizontal axes, a central post pivoted to the car above the doorway, having two'members spaced apart, between which edges of the doors may be disposed, and'a bolt secured to the central post and disposed across the slot. for engaging the recesses in the doors.

5. Inl vcombination with a car having va doorway, two doors with recesses, one pivoted at each side of the doorway on horizontal axes, a central post pivoted to the car above the doorway, having a slot in which edges of the doors maybe disposed, vand a bolt secured, to the cent-ral post. and disposed across the slot, for engaging the recesses in the doors, there being two orifices in the central post and an rorifice in each of the doorways, the centers of the orificesin the central post being out* of alinement with the orifices in the doors respectively.
