GRAIN-CAR DOOR.

Application filed A ri19. 1906, Serial No. 310.823

. To all whom it may concern:

. grooves 5 extend opened Be it known that we, ANDREW PEIRANO and WILLIAM GREENWOOD, citizens of the United States, residing at WVilson, in the county of Ellsworth and State of Kansas, have invented certain new and useful Improvements in Grain car Doors; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in grain car doors, and it consists in the construction, combination and arrangement of devices, hereinafter described and claimed.

The object of our invention. is to provide a grain car door of improved construction having an inner and an outer section, which may be readily closed and opened, and which when opened may be readily swung and secured under the roof of the car to dispose them out of the way, and which when closed coact with looking and guide rails in the door jambs to firmly secure them in place.

In the accompanying drawings,Figure 1 is an elevation of our improved grain door from the outer side, showing the door closed; Fig. 2 is a transverse sectional view of the same, taken on the plane indicated by the line a@ of Fig. 1, and showing the door in closed position in full lines, and in position ready to be swung up under the roof and disposed out of the way, in dotted lines; and Fig. 3 is a horizontal sec tional view of the same, taken on the plane indicated by the line b-b of Fig. 1. y

In the sides of the doorway are locking and guide rails, each of which comprises a fixed lower section 2 and an upper section 3 pivoted near its upper end, as at 4. The meeting ends of the lower and upper sections of the locking and guide rails are beveled so that they overlap and so that the upper sections are adapted to swing inwardly within the car, but are prevented from moving outwardly beyond the outer side thereof. Each of said sections is provided with an inner guide groove 5 and an outerguide groove 6. The inner guide from the upper ends. of the upper sections to within a suitable distance from the lower ends of the lower sections, The outer guide grooves 6 extendfrom the upper ends of the upper sections to the lower ends of the lower sections. A wear-strip 7 is Specification of Letters Patent.

secured on the door-sill, extends across the bottom of the door-Way and its ends bear against the outer flanges 9 of the locking and guide rails. Said locking and guide rails are provided on their inner sides with outwardly-extending flanges 9, which bear against the inner sides of the car wall at the sides of the door. The said flanges 9 of the lower sections 2 are secured to the wall as by means of screws or other suitable devices, while said flanges of the upper sections 3 f bear against the inner side of the wall when the door is swung downwardly, so as to cause the grooves 5, 6, of the upper sections to register with the corresponding grooves in the lower sections.

The outer door section 10 operates in the outer grooves 6, and is adapted to be lowered to the sill of the door-way, so as to close the lower portion thereof and to lie partly in the grooves 6 of the lower sections 2 and partly in the corresponding grooves in the upper sections The said door section is provided on its outer side with shoe-bars 11, the inner ends of which are pivotally connected thereto as by staples 12, and the outer ends of which are broadened to form heads 13 to bear frictionally against the outer sides of the flanges 8 of the locking and guide bars. Springs 14 are provided to normally press said shoe-bars outwardly to release them from said flanges of the locking and guide bars. Screws 15 are secured to and project outwardly from the door 10 and pass through openings in the shoe-bars. The springs 14 are hereshown as coilsprings placed on said screws and bearing between the door 10 and the inner sides of the shoe-bars. Locking nuts 16 having operating handles 17, whereby they may be readily turned, operate on the said screws 15 and bear against the outer sides of the said shoe-bars. It will be understood that by appropriately turning said nuts, the shoe-bars may be caused to frictionally engage the flanges 8 of the locking and guide rails, so as to lock the outer door section 10, either when raised or lowered. l/Vhen the said door section 10 is raised so as to beheld entirely in the upper sections of the locking and guide rails, and is clear of the lower sections of the locking and guide rails, the inner door 18 will be raised therewith, said inner door section having an arm 19 at'its upper side, which extends over the outer. door 10, and is engaged bythe latter when the outer door section is raised, for this purpose. When both of the said doors 20 g the latter serves to screen the upper and are thus raised clear of the lo wer sections of the locking and guide rails, the door sections may be turned inwardly and turned up into the roof of the car and there supported by a suitable hook, which may be engaged with a keeper-plate 21 that is secured on the outer side of the outer door section 10 at the lower portion thereof. Said keeper {iplate also serves to enable the outer door to be engaged by a bar and pried upwardly thereby to enable the doors to be opened when the car is loaded.

It will be observed by reference to Fig. 2, that while the outer door section 10 goes entirely to the bottom of the doorway, the in ner door section 18 is prevented by the inner guides 5 from being lowered to a corresponding extent, so that while the grain in the car is enabled to press against the lower or outer door section 10, and the inner, upper door 18,

major portion of the door section 10, so that said door section 10 is almost entirely re- I lieved of the stress or pressure of the grain,

hence the outer door section may be first raised to enable the grain to be discharged from the car by its own gravity underthe inner door section 18, and when the grain will no longer flow, the inner door section 18 is then raised, together with the outer door section, to the full extent.

From the foregoing description, taken in connection with the accompanying drawings,

the construction and operation of the invention will be readily understood without requiring a more extended explanation,

Various changes in-the form, proportion and the minor details ofconstruction may be resorted to without departing from the I principle or sacrificing any of the advantages of this invention, as defined by the appended claims.

Having thus described our invention, what we claim as new, and desire'to secure by Letters-Patent, is,--'

1. The combination, in a structure of the class described, of locking and guide rails having guide grooves in their opposing sides and exterior friction faces, a door guided in said grooves, shoe bars on the outer side of said door, pivotally connected thereto at their inner ends and having their outer ends extended over and opposed to the friction faces of the guide rails, screws secured to and projecting outwardly from the door and extending through said shoe bars, springs to move said shoe bars outwardly, and nuts on the screws to force the shoe bars against the friction faces of the guide rails.

2. In a structure of the class described, the combination with looking and guide rails each having a fixed lower member and an upper member pivoted at its upper end, said members having outer and inner guide grooves in their opposite sides, and said inner guide grooves of the lower members terminating at a point between the lower and upper ends thereof, and inner and outer door sections guided respectively in the said'inner and outer grooves, said outer door SQOJGIOH' having means to engage said lower guide rail members and lock said said inner door section when loweredbeing supported by the lower ends of the inner grooves, at a distance above the bottom of the structure and across the joints between the meeting ends of the upper and lower members of the guide rails.

In testimony whereof we have hereunto presence of two subscribing set our hands in witnesses.
