pplioation filed June Z. 1902.
Serial No. 109,853. (No model.)
To all whom if Tf1/ay concern,.-
Be it known that I, FRANCIS G. SUsEMIHL, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Gar-Doors, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to the inside door used in box-cars for shipping grain and like commodities and commonly called afgraincar doorg and the object of the invention is to provide a door of this character that will be tight-iitting, durable, capable of being easily operated, and be out of the way when not in use.
To this end the invention consists in certain novel features and details of construction and arrangements of parts, as hereinafter particularly set forth, and rillustrated in the accompanying-drawings, in which- Figure l is a vertical cross-section through the center of a box-car, showing the dooropenings on opposite sides equipped with my improved door, one of the doors being shown in position as in use and the other being shown in its out-oftheway position. Fig. 2 is a side elevation of the car, showing the door in position in the door-opening partly raised at one end. Fig. 3 is a vertical central longitudinal section through the car, showing an inside elevation of the door as in position for closing the door-opening. Fig. 4. is a horizontal section on plane w, Fig. 3, showing a portion of the door intop plan view. Fig. 5 is a detachedperspective view of the door. Figs. 6, 7, and 8 are vertical sections of different modifications of the door, as will be hereinafter more fully described.
In the drawings the invention is shown as applied to a box-car of standard construction provided with the usual door-openings A in the sides, formed between Vertical posts B.
C indicates the car-door considered as a whole. lt is vertically slidable and of a size to close the lower portion of the door-opening upon the inside up to the height of the girth D, to which height the car-body is boarded up on the inside, as usual. The door is composed of a trapezoidal body portion CL, preferably made of wood in the usual manner of constructing such doors, and of lateral extensions or wings b, secured thereto and .preferably made of malleable iron. The upper and lower edges of the body portion, which are parallel to each other, are of such respective length that when the door is in position in the door-opentween the door-posts and the adjacent edges of the body. These gaps are closed on the inside by means'of the extensions or wings Z) on the body, which form complementary parts of the d oor in such manner that it has the' quadrilateral shape and size requisite to overlap the door-posts on the inside and form a tight joint. The wings may be secured to the door-body in any suitable manner, preferably by making the wing wide enough to have a portion d thereof lap over the adjacent end of the door-body andsecuring it thereto, said overlapping portion being preferably on the outside of ,the door. Animportant feature of my invention consists in arranging this overlapping portion of the -wing in such a manner that all or at least the lower portion of the door-body (in the closed position of the door) is not in a vertical plane, but slants outwardly toward its base,which, as will be Well understood, has the advantage of relieving the door immediately from the weight pressing against it when the door is pried up for vu nloading the car. The portion d of the wing, to which the door-body is secured, and the portion cthereof,which forms the marginal verticaljend portions of the door, are connected by the intermediate web portion f, and this portion isin a plane at right angles to these first-mentioned portions and at the same time it is parallel with the ends of the door-body and forms an abutment for the same. Being thus constructed, it will be seen that the door is capable of being tilted to a certain degree within the door-opening without binding and jamming between the doorposts, thus permitting one end of thedoor to be pried up in advance of the other. To facilitate the prying up of the door, a metallic strip g, provided with a vertically-depending iange g', is secured to the lower edge of the door-body. When the door is closed, it rests upon this strip, and as the flange gf extends along the rear edge of the strip there will be formed a recess g2 between the lower edge of ing triangular' open gaps o are formed bethe door-body and the sill for the whole length of the door, in which a crowbar may be inserted at any point to pry up the door. This strip not only protects the lower edge of the door from possible damage by the crowbar and strengthens the door itself, but also by reason of the location of the ange g permits of giving the door the maximum outward slant. The depending edge strip g' supports the door upon a suitable metal sill h, formed with a raised shoulder i to form a tight joint with the edge strip, and raised portionsly' are formed or provided on the sill near the corners to form stops to hold the edge strips in position against the shoulder' t' and prevent any inward displacement of the door. As the principal pressure of the load will be against the lower portion of the door, it might be suficient to make only the lower portion of the door-body slant outwardly. Thus instead of slanting the Whole body, as shown in Figs. l to 5, the vertical cross-section thereof may be as shown in Figs. 6 and 7, in which the upper portion is vertical in the closed positions of the door. The lower portion of the door can thus be slanted more abruptly. Instead of the door lying almost wholly within the space between the door-posts, as in the previously-mentioned constructions, the slant may be increased, so that a considerable portion of the door-body projects into the car, as shown in Fig. 8. The modifications required in the constructions of the wings to admit of the described modilications will be readily understood. It will also be understood that the advantages resulting from the above-described constructions can be equally obtained with a trapezoidal door-body ot reversed forni from the one shown.
The car-door is guided on the inside by vertical guide-rods F, placed adjacent to the door-posts and extending up from the girth D to near the top of the car. As the car is boarded up on the inside only to the height of the girth, there will be pockets left between the frame-timbers above the girth, and the guide-rods F being placed in the pockets thus left adjacent to the door-posts and secured flush with the boarded up portion afford room for engagement with the brackets Gr, which are secured near the upper corners of the door and projecting laterally on the inside of the door-posts engage the guide-rods by means of slotted ends c. At their upper ends the guide-rods are bent inwardly in order to clear the braces H and form restsZ for the support of the car-door when not in use, as shown in Fig. l to the right. In this latter position the car-door is completely suspended out of the Way against the roof of the car by the brackets resting upon the rests Z of the guide-rods and by means of hooks I, pivotally secured to trimmers J and adapted to engage with the bottom edge of the cardoor, as shown. To prevent accidental disengagement, each hook is provided with a locking-bolt K.
When the door is in its closed position, it may be, as is usual, locked against accidental displacement by means of the hook L, secured to the door-posts. These hooks consist of a plate hook-shaped at both ends on opposite sides and provided with a longitudinal slot through which the pivot-pin passes, which secures it to the side of the post in such mauner that either end may be hooked over the edge of the door. Another plate M is Vertically slidingly secured to the post in such relation to the hook that the latter may be locked thereby in its closed position, While the construction of the hook permits the same to be engaged with the door no matter in what position it may be, while at the same time these parts do not form any obstruction in the doorway and are not liable to be damaged.
The operation of the Various parts will be readily understood from the above description, and the construction, which is simple, cheap, and efficient, accomplishes the objects of the invention. When it is considered that grain-car doors soon Wear out, mostly as a result from the operation of opening them in unloading the cars, it will be readily understood that myconstruction,owing to the slanting position of the door which requires but small force to pry it up, greatly lengthens the life of the door.
