A J. MATTSON GRAINDooR Filed Feb. 1l 1924 atto: nu:
Patented Jniy i5, 1.924.
JACOB MATTSON, OF DUIIUWJTH,MIIN'NESOTAe GRAIN DOOR.
Application led February T 0 all w iom it may con-cern.:
Be it known that I, JACOB MA'rrsoN, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful improvements in Grain Doors, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to closures for door openings and has special reference to what is commonly known as grain doors forrailway cars.
The principal object of the invention is to provide a simple form of rportable closure for door opening.
Another object is to provide a closure which may be readily fitted to door openings of varying widths, and one readily removed or applied to an opening without the use of crow bars, o-r other heavy tools.
@ther objects and advantages of the invention will appear in the further description thereof.
Referring nowto the accompanying drawing forming part of this application and in which like reference characters indicate like parts:
Figure 1 is a front elevation of the completely assembled door closure as applied to the door opening of a car:
Figure 2 is an inside elevation of the door section: and
Figure 3 is an enlarged horizontal sectional view of one corner of the door section taken on the line 3-3, Figure 1-1 and Figure 4 is an enlarged end elevation of the door section,
My improved form of door preferably comprises an elongated section which is illustrated in the accompanying drawing, such being illustrated as provided with an auxiliary or smaller door through which the initial discharge of the contents of the car may be accomplished so as to free the door.
The section as illustrated at 1, is preferably made up of two thicknesses of lumber Vand reinforced upon the backthereof by the longitudinally attached strips 2 and 3, the latter being adjacent the lower edge of the section and the former spaced downwardly somewhat from the upper edge of the section, and they are so spaced as to overlap the upper and lower edges of the elongated rectangularly shaped opening O formed in the door. Two vertical reinforcing strips or stiles 4 are placed at the ends of the opening 11, 1924:. Serial No. 691,938.
O to overlap saine, they all being securely nailed or fastened to the door section.
The opening() is closed by the removable ,door 5 which fits therewithin and abuts entirely about its edges against the strips 2, 8 and 4f.V This door 5 is provided adjacent keither end with a vertically disposed staple 6 each carrying two hasps 7 and 8, the u per hasps being engaged over suitable stapies 9 laced within the door section 1, while the owe-r hasps are similarly engagedoverlike staples 10 adjacent the lower edge of the door section, and common pins, as indicated at 11, Vmay be used for holding the hasps in position.
In the opening of this auXiliary door it isY readily seen ythat if the lower pins 11 are removed there might be sufficient of the contents of the car run out without removing the upper pins whatever so that it may not be at all times necessary to entirely remove the auxiliary door.
Horizontally elongated slots 12 are formed adjacent each corner of the door section 1 and just above the reinforcing strips 2 and 3 in which are carried eye-bolts 13, they each being provided with a nut 14 upon the inner side of the door; the eye of the bolts extending through the slots to the outer side, of the door. A metallic wearing plate 15 is provided about the inner edges of each of the slots 12 against which the nut bears and these slots are each housed in by a suitable wooden box like structure indicated at 17. This housing is preferably flush with the outer faces of the reinforcing strips on the back of the door, the same being for the purpose of pre-venting any grain, or whatever the contents of the car r-iiay be, from leaking therethrough.
Each eye-bolt 13 carries a small hasp 18 which is designed to be engaged ,over a suitable staple 19 driven into the face of the door frame for such purpose, and the bolts being slidable longitudinally of the slots 12 permit of same being conveniently adjusted to door openings of various widths. To prevent the bolts from becoming Wholly unscrewed from the nuts 14 I prefer to have the inner ends thereof slightly upset, thus providing for ready longitudinal adjustment of the bolts by turning same to more neatly register with the staples 19 regardless of their exact location.
At V2O I have illustrated a plurality of buttons which are pivotally mounted upon the section' 1 and designed tovoverlap the edges of the auxiliary door 5 as an additional means of keeping the door tightly in position, and such may or may not be used as desired.
Furthermore I have illustrated at 21 short lengths of chain loosely uniting the auxiliary door With the door section 1 so as toy prevent their possible separation and thei'auXiliary door becoming lost.
From lthe foregoing it is evident that I have devised an exceedingly simple grain fdoor section and one admirably adapted for the purpose intended. ,I Having thus described my invention,
"what I claim and desire to secure by Lettion, said lower strip overlapping the lower edge of the opening While the uppermost strip also overlaps the upper edge of the opening,l vertically disposed reinforcing strips the ends of which abut against the opposed edges of the horizontal strips and overlapping the ends of the opening, vertically spaced slots at either end of the section spaced slightly above the upper edges of the horizontal strips said slots having fastening bolts therein, box like housings about. the ends of the bolts Which extend through the section upon the reinforced side thereof, the upper edges of the reinforcing strips forming the lower walls of the box like housings and the outer faces of the housings and strips being flush, and a door for said opening Within the section being suspended adjacent the opening.
In testimony whereof I hereunto atix my signature in the presence of two Witnesses.
